    Until high definition television (ATV) arrives, in the U.S. we must still contend with the National Television Systems Committee (NTSC) video standard (or PAL or SECAM-depending on your country). NTSC, a 40-year old standard designed for transmission of color video camera images over a small bandwidth, is not well suited for the sharp, full-color images that todays computers are capable of producing. PAL and SECAM also suffers from many of NTSC`s problems, but to varying degrees. Video professionals, when working with computer graphic (CG) images, use two monitors: a computer monitor for producing CGs and an NTSC monitor to view how a CG will look on video. More often than not, the NTSC image will differ significantly from the CG image, and outputting it to NTSC as an artist works enables the him or her to see the images as others will see it. Below are thirteen guidelines designed to increase the quality of computer graphics recorded onto video tape. Viewing your work in NTSC and attempting to follow the below tips will enable you to create higher quality videos. No video is perfect, so don`t expect to abide by every guideline every time.

    Brunner, J; Krummenauer, F; Lehr, H A

    2000-04-01

    Study end-points in microcirculation research are usually video-taped images rather than numeric computer print-outs. Analysis of these video-taped images for the quantification of microcirculatory parameters usually requires computer-based image analysis systems. Most software programs for image analysis are custom-made, expensive, and limited in their applicability to selected parameters and study end-points. We demonstrate herein that an inexpensive, commercially available computer software (Adobe Photoshop), run on a Macintosh G3 computer with inbuilt graphic capture board provides versatile, easy to use tools for the quantification of digitized video images. Using images obtained by intravital fluorescence microscopy from the pre- and postischemic muscle microcirculation in the skinfold chamber model in hamsters, Photoshop allows simple and rapid quantification (i) of microvessel diameters, (ii) of the functional capillary density and (iii) of postischemic leakage of FITC-labeled high molecular weight dextran from postcapillary venules. We present evidence of the technical accuracy of the software tools and of a high degree of interobserver reliability. Inexpensive commercially available imaging programs (i.e., Adobe Photoshop) provide versatile tools for image analysis with a wide range of potential applications in microcirculation research.

    1999-03-01

    Since the first experiments on magnetic recording by Valdemar Poulsen in 1898 the use of this technology has grown tremendously and magnetic storage is used in almost every home in the world. A special challenge was the recording of video signals which need a high bandwidth. In the 1950s, television broadcasts had started which created a need for storage in the broadcast world. The first broadcast recorder was the Quadruplex from Ampex in 1956. Later solutions were found for application in the consumer market. Better mechanics, magnetic tapes and recording heads allowed the mass production of a cheap consumer recorder. The size and weight decreased tremendously and portable camcorders are very common. Recording of broadcasts, video rental and home movies are now very popular. The factors which contributed to the maturing of this technology will be reviewed in this paper.

    Full Text Available Introduction: Medical student should be trained in medical ethics and one of the most essential issues in this field is taking informed consents. In this research, we compared the effect of effectiveness of teaching methods on students’ ability in taking informed consent from patients. Methods: This semi-experimental study was carried out on fifty eight subjects from the 4th-year students of Shiraz University of Medical Sciences who attended in medical ethics course before their ‘clinical clerkship’training.Method of sampling was census and students were randomly allocated into two groups of control group (n=28 was trained in traditional lecture-based class and the case groupnamed as A1 (n=22 were taught by video-taped examples of standardized patient.Then A1 group attended in traditional lecture-based classes named as A2. The groups were evaluated in terms the ability of recognition of ethical issues through the scenario based ethical examination before and after each training. Scenarios were related to the topics of informed consent. Data were analyzed by SPSS 14 software using descriptive statistics and anova test. P-value less than 0.05 was considered as significant. Results: The mean scores results of A2, A1 and B group were found to be 7.21, 5.91 and 5.73 out of 8, respectively. Comparison between the groups demonstrated that the ability of taking informed consent was significantly higher in A2 group (p<0.001, followed by A1 group (p<0.05, while was the least in the B group (p=0.875. Conclusion: According to this research, lecture-based teaching is still of great value in teaching medical ethics, but when combined with standardized patient, the outcome will be much better. It should be considered that mixed methods of teaching should be used together for better result.

    2015-10-01

    This study investigated the utility of video blogs in improving EFL students' performance in giving oral presentations and, further, examined the students' perceptions toward video blogging. Thirty-six English-major juniors participated in a semester-long video blog project for which they uploaded their 3-min. virtual presentation clips over 18 weeks. Their virtual presentation clips were rated by three raters using a scale for speaking performance that contained 14 presentation skills. Data sources included presentation clips, reflections, and interviews. The results indicated that the students' overall presentation performance improved significantly. In particular, among the 14 presentation skills projection, intonation, posture, introduction, conclusion, and purpose saw the most substantial improvement. Finally, the qualitative data revealed that learners perceived that the video blog project facilitated learning but increased anxiety.

  18. Objective video presentation QoE predictor for smart adaptive video streaming

    How to deliver videos to consumers over the network for optimal quality-of-experience (QoE) has been the central goal of modern video delivery services. Surprisingly, regardless of the large volume of videos being delivered everyday through various systems attempting to improve visual QoE, the actual QoE of end consumers is not properly assessed, not to say using QoE as the key factor in making critical decisions at the video hosting, network and receiving sites. Real-world video streaming systems typically use bitrate as the main video presentation quality indicator, but using the same bitrate to encode different video content could result in drastically different visual QoE, which is further affected by the display device and viewing condition of each individual consumer who receives the video. To correct this, we have to put QoE back to the driver's seat and redesign the video delivery systems. To achieve this goal, a major challenge is to find an objective video presentation QoE predictor that is accurate, fast, easy-to-use, display device adaptive, and provides meaningful QoE predictions across resolution and content. We propose to use the newly developed SSIMplus index (https://ece.uwaterloo.ca/~z70wang/research/ssimplus/) for this role. We demonstrate that based on SSIMplus, one can develop a smart adaptive video streaming strategy that leads to much smoother visual QoE impossible to achieve using existing adaptive bitrate video streaming approaches. Furthermore, SSIMplus finds many more applications, in live and file-based quality monitoring, in benchmarking video encoders and transcoders, and in guiding network resource allocations.

    1994-01-01

    With NASA placing increased emphasis on transferring technology to outside industry, NASA researchers need to evaluate many aspects of their efforts in this regard. Often it may seem like too much self-promotion to many researchers. However, industry's use of video presentations in sales, advertising, public relations and training should be considered. Today, the most typical presentation at NASA is through the use of vu-graphs (overhead transparencies) which can be effective for text or static presentations. For full blown color and sound presentations, however, the best method is videotape. In fact, it is frequently more convenient due to its portability and the availability of viewing equipment. This talk describes techniques for creating a video presentation through the use of a combined researcher and video professional team.

    The aim of the present study was to investigate the effects of video presentations of natural landscapes on European starlings' (Sturnus vulgaris) stereotypic behaviours (SBs) and other abnormal repetitive behaviours (ARBs) and to evaluate the impact of past experience by comparing wild-caught and hand-reared starlings' reactions. Ten wild-caught and five hand-reared starlings were presented 1-hour videos of landscapes twice a day for five successive days, while a control group of eight wild-caught and four hand-reared starlings was presented a grey screen for the same amount of time. The analysis of the starlings' behaviour revealed that the video presentations of landscapes appeared to have a positive but limited and experience-dependent effect on starlings' SBs and other ARBs compared to the controls. Indeed, whereas video presentations seemed to modulate high rates of SBs and ARBs, they did not appear to be enriching enough to prevent the emergence or the development of SBs and ARBs in an impoverished environment. They even appeared to promote a particular type of SB (somersaulting) that is thought to be linked to escape motivation. The fact that this effect was observed in hand-reared starlings suggests that videos of landscapes could elicit motivation to escape even in birds that never experienced outdoor life. These results highlight the importance of investigating stereotypic behaviour both quantitatively and qualitatively in order to provide crucial clues on animal welfare. PMID:24827457

    A small fragment of Leonid storm video data from the 1999 Leonid Multi-Instrument Aircraft Campaign is analyzed visually at exhaustion to measure the detection efficiency of visual scanning techniques and calibrate the meteor flux at the peak of the storm. The high meteor rate makes it possible to obtain statistically meaningful results over short time intervals. We arrive here at a flux estimate for the peak of the 1999 Leonid storm of 2.8+-0.4km^2/hr (m < +6.5), a factor of two higher than reported elsewhere.

    Chow, Amy Yin Man

    2010-01-01

    Video-taping clinical sessions is a common practice among social workers so that the tapes may be used for clinical supervision and reviewed with the individuals or families involved. They are usually underused for research purposes. This article reports on an innovative research method using such tapes as a basis for clinical data mining to explore the bereavement experience of Chinese people in Hong Kong. Using this data, a rich item pool, containing both negative and positive reactions, was generated to allow the development of a culturally relevant measurement tool of grief reactions. The data also facilitated theory building in the area of grief and bereavement. This study extended the use of video-tapes in clinical sessions for research purposes and helped to collect reliable and timely data in a non-intrusive way. It has also advanced the use of quantitative data in the clinical data-mining approach. The study encouraged collaboration between clinicians and researchers to develop knowledge and skills about their special target group of clients.

    2017-03-01

    We performed simultaneous recordings of electroencephalography (EEG) from multiple students in a classroom, and measured the inter-subject correlation (ISC) of activity evoked by a common video stimulus. The neural reliability, as quantified by ISC, has been linked to engagement and attentional modulation in earlier studies that used high-grade equipment in laboratory settings. Here we reproduce many of the results from these studies using portable low-cost equipment, focusing on the robustness of using ISC for subjects experiencing naturalistic stimuli. The present data shows that stimulus-evoked neural responses, known to be modulated by attention, can be tracked for groups of students with synchronized EEG acquisition. This is a step towards real-time inference of engagement in the classroom.

    Full Text Available Surgical treatment of female stress urinary incontinence (SUI has become very pop- ular after respectable success with minimal invasive surgeries. This is the first report of long term vaginocutaneous fistula (VCF plus inguinal abcess after tension-free vaginal tape (TVT. A 67 year-old woman with vaginal discharge lasting more than 3 years complained with a painful swelling in the left inguinal area for the last three months. She had a medical history of TVT sling procedure for SUI six years ago. She had no history of pelvic surgery, cancer treatment or pelvic irradiation before or after TVT sling. No urethrovaginal or vesicovaginal fistula was found in physical examination and cystocopy. MRI showed a vaginocutenaous fistula and inguinal abcess. This case highlights the need for a high index of suspicion for VCF after TVT.

    The process of digital capture, editing, and archiving video has become an important aspect of documenting arthroscopic surgery. Recording the arthroscopic findings before and after surgery is an essential part of the patient's medical record. The hardware and software has become more reasonable to purchase, but the learning curve to master the software is steep. Digital video is captured at the time of arthroscopy to a hard disk, and written to a CD at the end of the operative procedure. The process of obtaining video of open procedures is more complex. Outside video of the procedure is recorded on digital tape with a digital video camera. The camera must be plugged into a computer to capture the video on the hard disk. Adobe Premiere software is used to edit the video and render the finished video to the hard drive. This finished video is burned onto a CD. We outline the choice of computer hardware and software for the manipulation of digital video. The techniques of backup and archiving the completed projects and files also are outlined. The uses of digital video for education and the formats that can be used in PowerPoint presentations are discussed.

    2015-10-01

    The transobturator tape (TOT) is an effective treatment for stress urinary incontinence (SUI). Erosion of TOT mesh is a recognised complication requiring excision. A retrospective analysis of 228 females undergoing a TOT procedure over 4 years identified 16 patients (7%) that underwent excision of eroded mesh. Mean age of patients requiring excision was 48.8 years and mean weight was 72.7kg. Mean time to re-presentation was 14.5 months. Presenting symptoms included dyspareunia in 9 patients (56.2%), dysuria in 3 (18.7%), persistent incontinence in 3 (18.7%) and groin pain in one patient. Ten patients (62.5%) had a prior urogynecological procedure. After excision of eroded tape-mesh, 7 (43.7%) required a rectus fascial sling and 4 (25%) underwent repeat TOT for recurrence of SUI. Five patients (31.2%) required no further surgery. At present 10 patients (62.5%) report resolution of SUI, 4 (25%) report mild SUI and 2 (12.5%) patients have moderate/severe SUI. Resolution of symptoms occurred in the majority of patients after excision of eroded mesh and an additional anti-incontinence procedure.

    Precursor powders containing different lead-rich phases: (a) Ca2PbO4, (b) Pb-3(Sr,Bi)(3)Ca2CuOy (3321), were prepared by controlling the calcination temperature and atmosphere. Monofilament tapes were fabricated using those two powders. It has been found that both the microstructure and critical...... current depended strongly on the nature of the lead-rich phase. Tapes fabricated using the precursor with the Ca2PbO4 phase (tape T1) had a much lower optimum sintering temperature and a narrower temperature window than tapes fabricated using the precursor with the 3321 phase (tape T2). The critical...... in tape T2. It can be concluded that the control of the lead-rich phases present in the precursors is an effective way to improve the Jc values.

    Bozdag, Ali Dogan

    2008-07-01

    Presentations at scientific congresses and symposiums can be in two different forms: poster or oral presentation. Each method has some advantages and disadvantages. To combine the advantages of oral and poster presentations, a new presentation type was conceived: "video in poster." The top of the portable digital video display (DVD) player is opened 180 degrees to keep the screen and the body of the DVD player in the same plane. The poster is attached to the DVD player and a window is made in the poster to expose the screen of the DVD player so the screen appears as a picture on the poster. Then this video in poster is fixed to the panel. When the DVD player is turned on, the video presentation of the surgical procedure starts. Several posters were presented at different medical congresses in 2007 using the "video in poster" technique, and they received poster awards. The video in poster combines the advantages of both oral and poster presentations.

  17. Optimized static and video EEG rapid serial visual presentation (RSVP) paradigm based on motion surprise computation

    Science.gov (United States)

    Khosla, Deepak; Huber, David J.; Bhattacharyya, Rajan

    2017-05-01

    In this paper, we describe an algorithm and system for optimizing search and detection performance for "items of interest" (IOI) in large-sized images and videos that employ the Rapid Serial Visual Presentation (RSVP) based EEG paradigm and surprise algorithms that incorporate motion processing to determine whether static or video RSVP is used. The system works by first computing a motion surprise map on image sub-regions (chips) of incoming sensor video data and then uses those surprise maps to label the chips as either "static" or "moving". This information tells the system whether to use a static or video RSVP presentation and decoding algorithm in order to optimize EEG based detection of IOI in each chip. Using this method, we are able to demonstrate classification of a series of image regions from video with an azimuth value of 1, indicating perfect classification, over a range of display frequencies and video speeds.

  18. Comparison of relative effectiveness of video with serial visual presentation for target reconnaissance from UASs

    Skirlo, Frank E.; Matthews, Anthony J.; Friedman, Melvin; Mark, Brian L.

    2016-05-01

    Reconnaissance from an unmanned aerial systems (UAS) is often done using video presentation. An alternate method is Serial Visual Presentation (SVP). In SVP, a static image remains in view until replaced by a new image at a rate equivalent to the live video. Mardell et al. have shown, in a forested environment, that a higher fraction of targets (people lost in the forest), are found with SVP than with video presentation. Here Mardell's experiment is repeated for military targets in forested terrain at a fixed altitude. We too find a higher fraction of targets are found using SVP rather than video presentation. Typically it takes five seconds to cover a video field of view and at 30 frames per second. This implies that, for scenes where the target is not moving, 150 video images have nearly identical information (from a reconnaissance point of view) as a single SVP image. This is highly significant since transmission bandwidth is a limiting factor for most UASs. Finding targets in video or in SVP is an arduous task. For that reason we also compare aided target detection performance (Aided SVP) and unaided target detection performance on SVP images.

    To assess different methods of recording angiographic simulations and to determine how such recordings might be used for training and research. Two commercially available high-fidelity angiography simulations, the Mentice Vascular Interventional Simulation Trainer and the Simbionix AngioMentor, were used for data collection. Video and audio records of simulated procedures were created by different methods, including software-based screen capture, video splitters and converters, and external cameras. Recording parameters were varied, and the recordings were transferred to computer workstations for postprocessing and presentation. The information displayed on the simulators' computer screens could be captured by each method. Although screen-capture software provided the highest resolution, workflow considerations favored a hardware-based solution that duplicated the video signal and recorded the data stream(s) at lower resolutions. Additional video and audio recording devices were used to monitor the angiographer's actions during the simulated procedures. The multiple audio and video files were synchronized and composited with personal computers equipped with commercially available video editing software. Depending on the needs of the intended audience, the resulting files could be distributed and displayed at full or reduced resolutions. The capture, editing, presentation, and distribution of synchronized multichannel audio and video recordings holds great promise for angiography training and simulation research. To achieve this potential, technical challenges will need to be met, and content will need to be tailored to suit the needs of trainees and researchers.

    We show that metal nanoparticles can be used to improve the performance of super-resolution fluorescence nanoscopes based on stimulated-emission-depletion (STED). Compared with a standard STED nanoscope, we show theoretically a resolution improvement by more than an order of magnitude, or equivalently, depletion intensity reductions by more than 2 orders of magnitude and an even stronger photostabilization. Moreover, we present experimental evidence that an optimum resolution, limited by the sizes of the particles used, can be reached for the hybrid NPs for a power of the STED beam one order of magnitude smaller than for the bare cores.

    Diverse products either based solely on or incorporating Shape Memory Alloys (SMA) have and are being made in a wide range of industries, and IP is being captured. Why then compared to SE (superelastic) Nitinol, and especially conventional technology, do so few ideas reach production? This presentation delves deeply into this topic in reaching the final assessment that SMA actuators are indeed now a viable practical technology. The presentation begins with an introduction to and description of the fundamental basis of SMA actuator technology. Examples of multiple commercially available geometric forms of SMA actuators are given and the functionalities that they provide are described. This is followed by examples of multiple commercial products incorporating such SMA actuators. Given that there are literally millions of commercial products incorporating conventional actuator technologies, indications are given as to why there are their less than 1000 that utilize SMA. Experience based challenges to the commercial use of SMA actuators are described. Besides having to compete with existing non-SMA technology which is quite mature additional challenges that are unique to SM actuators are indicated these including a wider than expected set of technical engineering problems and challenges and that a broader scope of dynamics is required.

  3. Three-dimensional video presentation of microsurgery by the cross-eyed viewing method using a high-definition video system.

    2011-01-01

    Three-dimensional (3-D) video recording of microsurgery is a more promising tool for presentation and education of microsurgery than conventional two-dimensional video systems, but has not been widely adopted partly because 3-D image processing of previous 3-D video systems is complicated and observers without optical devices cannot visualize the 3-D image. A new technical development for 3-D video presentation of microsurgery is described. Microsurgery is recorded with a microscope equipped with a single high-definition (HD) video camera. This 3-D video system records the right- and left-eye views of the microscope simultaneously as single HD data with the use of a 3-D camera adapter: the right- and left-eye views of the microscope are displayed separately on the right and left sides, respectively. The operation video is then edited with video editing software so that the right-eye view is displayed on the left side and left-eye view is displayed on the right side. Consequently, a 3-D video of microsurgery can be created by viewing the edited video by the cross-eyed stereogram viewing method without optical devices. The 3-D microsurgical video provides a more accurate view, especially with regard to depth, and a better understanding of microsurgical anatomy. Although several issues are yet to be addressed, this 3-D video system is a useful method of recording and presenting microsurgery for 3-D viewing with currently available equipment, without optical devices.

    A method for creating and presenting video-recorded synchronized audiovisual stimuli at a high frame rate-which would be highly useful for psychophysical studies on, for example, just-noticeable differences and gating-is presented. Methods for accomplishing this include recording audio and video separately using an exact synchronization signal, editing the recordings and finding exact synchronization points, and presenting the synchronized audiovisual stimuli with a desired frame rate on a cathode ray tube display using MATLAB and Psychophysics Toolbox 3. The methods from an empirical gating study (Moradi, Lidestam, & Rönnberg, Frontiers in Psychology 4:359, 2013) are presented as an example of the implementation of playback at 120 fps.

    Improved tape guiding and tape dimensional stability are essential for magnetic tape linear recoding formats to take advantage of vastly increased track density and thereby achieve higher storage capacities. Tape guiding is dependent on numerous parameters, such as type of the guides and tape path geometry, quality of virgin tape edge, drive operating parameters (e.g., tape speed and tape tension), mechanical properties of the tape, and tape geometry (e.g., cupping and curvature). The objective of the present study is to evaluate guiding and tribological performance of single-flanged guides with porous air bearings in a linear tape drive. A comparison of guiding performance of the dual flanged stationary guides and single-flanged guides with porous air bearings is performed. The effect of tape path geometry, drive operating conditions (speed and tension) and tape edge quality of factory-slit tapes on tape guiding are evaluated during short-term tests. A lateral force measurement technique is used to measure the force exerted by the tape edge on the guide flange. A technique for the lateral tape motion measurement is used to study the effect of continuous sliding on tape guiding. Wear tests up to 5000 cycles are conducted and coefficient of friction and lateral tape motion are monitored to study the effect of drive operating conditions (speed and tension), edge quality of factory-slit tapes and tape thickness on tape guiding. Optical microscopy, atomic force microscopy and scanning electron microscopy are employed to study and quantify the quality of tape edge.

    We report an adult patient presenting with choreiform movements 4 days after a large intravenous dose of cocaine. These movements were transitory and they normalized a week after admission. We believe this to be the first video case of acute chorea secondary to cocaine--a phenomenon popularly known as "crack dancing. " Cocaine abuse is associated with a wide range of movement disorders, including dystonia and exacerbation of Tourette's syndrome, multifocal tics, opsoclonus-myoclonus, choreiform movements, and stereotyped behavior known as "punding." Transient choreiform movements with a typical duration of 2 to 6 days are recognized by cocaine abusers themselves as crack dancing, but are infrequently reported. We present a video report of a patient with cocaine dependency and choreiform movements that normalized within a week of admission.

    2012-11-01

    Full Text Available The current research sought to explore the effectiveness of using videos presenting speakers’ gestures and facial clues on Iranian EFL learners’ listening comprehension proficiency. It was carried out at Ayandeh English Institute among 60 advanced female learners with the age range of 17-30 through a quasi-experimental research design. The researcher administered a TOEFL test to determine the homogeneity of the participants regarding both their general English language proficiency level and listening comprehension ability. Participants were randomly assigned into two groups. After coming up with the conclusion that the two groups were homogeneous,  during 10 sessions of treatment, they received two different listening comprehension techniques, i.e. audio-visual group watching the video was equipped with the speaker’s gestures and facial clues, while the audio-only group could just listen to speaker’s voice and no additional clue was presented. Meanwhile, the participants were supposed to answer the questions related to each video. At the end of the treatment, both groups participated in the listening comprehension test of the Longman TOEFL test as the post-test. A t-test was used to compare the mean scores of the two groups, the result of which showed that the learners’ mean score in the audio-visual group was significantly higher than the learners’ mean score in the audio-only group. In conclusion, the result of this study suggests that foreign language pedagogy, especially for adult English learners, would benefit from applying videos presenting speakers’ gestures and facial clues.

    Merkle, Philipp; Müller, Karsten; Wiegand, Thomas

    2010-07-01

    An overview of existing and upcoming 3D video coding standards is given. Various different 3D video formats are available, each with individual pros and cons. The 3D video formats can be separated into two classes: video-only formats (such as stereo and multiview video) and depth-enhanced formats (such as video plus depth and multiview video plus depth). Since all these formats exist of at least two video sequences and possibly additional depth data, efficient compression is essential for the success of 3D video applications and technologies. For the video-only formats the H.264 family of coding standards already provides efficient and widely established compression algorithms: H.264/AVC simulcast, H.264/AVC stereo SEI message, and H.264/MVC. For the depth-enhanced formats standardized coding algorithms are currently being developed. New and specially adapted coding approaches are necessary, as the depth or disparity information included in these formats has significantly different characteristics than video and is not displayed directly, but used for rendering. Motivated by evolving market needs, MPEG has started an activity to develop a generic 3D video standard within the 3DVC ad-hoc group. Key features of the standard are efficient and flexible compression of depth-enhanced 3D video representations and decoupling of content creation and display requirements.

    The 3480 tape format is a magnetic tape data storage format developed by IBM. The cartridge contains a single reel. IBM’s 3480 cartridge tape system sought to replace the traditional reels of magnetic tape in the computer center. Because of their speed, reliability, durability and low media cost, these tapes and tape drives are still in high demand. A hallmark of the genre is transferability. Tapes recorded with one tape drive are generally readable on another drive, even if the tape drives were built by different manufacturers.

  15. DV/HDV tape drive synchronization for immediate preview of dual camera recordings

    Wimmer, Peter

    2007-02-01

    Dual DV or HDV camcorder setups are widely used to record stereoscopic video content. However, even when using a remote control to operate the camcorders synchronously, the number of recorded frames per scene is slightly different on the left and right tape. The different lengths make it impossible to play back the recorded content immediately. Up to now, both tapes had to be transferred to a hard disc and edited scene by scene. This paper presents a software-only solution to synchronize a pair of DV or HDV camcorders: Playback is assumed to be out of sync whenever a scene change does not occur at exactly the same time on the left and right tape. In such a case, the first tape is stopped until the scene change occurs on the second tape as well. Once both tapes have reached the scene change, playback on both drives is resumed. Detecting scene changes by means of image analysis is unreliable and CPU intensive. Consequently, we suggest a better method based on the recording date and time embedded in the compressed stream. To test the suggested solution, tape synchronization capabilities have been added to the Stereoscopic Multiplexer, a multiplexing solution for the Microsoft Windows platform.

    The ankle is frequently injured in sporting activities, and therefore it is frequently protected with prophylactic ankle taping. This study aimed first, to compare the mechanical fatigue of two types of prophylactic ankle taping after 30 minutes of intense exercise, one made with elastic tape (ET) and the other with inelastic tape (IT), and second, to investigate the subjects' perception on the tape restriction and comfort. Twenty-seven active women (mean age, 20.6 +/- 4.1 years), without previous ankle injuries volunteered for the study. The participants were tested on three different conditions: with elastic ankle taping, with inelastic taping, and without taping, before and after 30 minutes of intense exercise. The ankle passive ranges of movement (ROMs) were measured before and after exercise, and a subjective scale on taping comfort and restriction was completed by the subjects. Both types of ankle taping showed less ROM restriction after 30 minutes of exercise in inversion (IT = 27% and ET = 21%), and plantarflexion (IT = 8% and ET = 6%). The IT showed more loss of restriction than the ET, with significant differences in inversion (p taping because it produces the same restriction in the ROM as the IT with less taping fatigue, and is perceived as more comfortable and less restrictive by the users.

  19. Preschoolers' Recall of Science Content From Educational Videos Presented With and Without Songs

    Science.gov (United States)

    Schechter, Rachel L.

    This experimental investigation evaluated the impact of educational songs on a child's ability to recall scientific content from an educational television program. Preschoolers' comprehension of the educational content was examined by measuring children's ability to recall the featured science content (the function of a pulley and its parts) and their use of the precise scientific terms presented in the episode. A total of 91 preschoolers were included (3-5 years old). Clusters of children were randomly assigned to a control group or one of three video groups: (a) Dialogue Only, which did not include a song; (b) Dialogue Plus Lyrics, which included a song; or (c) Lyrics Only, which consisted of a song, played twice. Results from interviews suggested that children from all video groups (lyrics and/or dialogue) were able to explain the form and function of a pulley better than the control group. The data suggested that children from the Lyrics Only group understood the science content because of the visual imagery, not through the information provided in the lyrics. In terms of precise vocabulary terms, significantly more children in the Dialogue Only group recalled at least one precise term from the program compared to the Lyrics Only group. Looking at the interview as a whole, the children's responses suggested different levels of scientific understanding. Children would require additional teacher-led instruction to deepen their scientific understanding and to clarify any misconceptions. This paper discusses implications of these findings for teachers using multi-media tools in the science classroom and producers creating new educational programming for television and other platforms.

    Wong, Victoria S S; Stevenson, Matthew; Selwa, Linda

    2013-04-01

    We evaluated videos on the social media website, YouTube, containing references to seizures and epilepsy. Of 100 videos, 28% contained an ictal event, and 25% featured a person with epilepsy recounting his or her personal experience. Videos most commonly fell into categories of Personal Experience/Anecdotal (44%) and Informative/Educational (38%). Fifty-one percent of videos were judged as accurate, and 9% were inaccurate; accuracy was not an applicable attribute in the remainder of the videos. Eighty-five percent of videos were sympathetic towards those with seizures or epilepsy, 9% were neutral, and only 6% were derogatory. Ninety-eight percent of videos were thought to be easily understood by a layperson. The user-generated content on YouTube appears to be more sympathetic and accurate compared to other forms of mass media. We are optimistic that with a shifting ratio towards sympathetic content about epilepsy, the amount of stigma towards epilepsy and seizures will continue to lessen. Copyright © 2013 Elsevier Inc.

Accessed 6 March 2013, 4), reports regarding 'usual' Internet teleconferences or tele-lectures employing a telecommunication system for business use are very rare. Medical teleconferences and tele-lectures on the Internet were held three times between our institutions and other institutions, using the 'HD Com' made by Panasonic (HD Com. http://panasonic.biz/com/visual/ . Accessed 6 March 2013, 5), which is a high-definition telecommunication system for business tele-meeting. All of our medical telecommunications were successfully completed without any troubles. This system allows for all kinds of presentations using personal computers to be made from each station, so that discussions with high-definition surgical video presentation, which has recently been developed, could be effortlessly established despite the distance between institutions. Unlike telecommunication using advanced academic networks, this system can run without any need for specific engineering support, on the usual Internet. Medical telecommunication employing this system is likely to become common among ordinary hospitals in the near future.

    This paper presents an AC loss study of horizontally parallel HTS tapes. We proposed to use three parallel HTS tapes as an example. The AC losses of the middle and end tape of three parallel tapes have been measured using the electrical method and compared to those of an individual tape. The effect of the interaction between tapes on AC losses has been analysed, and compared with finite-element method (FEM) simulations using the 2D H -formulation implemented in COMSOL Multiphysics. By using FEM simulations, the cases of increasing number of parallel tapes have been considered, and the normalised ratio between the total average AC losses per tape and the AC losses of an individual single tape has been calculated for different gap distances. We proposed a new parameter, Ns , a turning point for number of tapes, to divide Stage 1 and Stage 2 for the AC loss study of horizontally parallel tapes. For Stage 1, N Ns , the total average losses per tape decrease with the increasing number of tapes. The analysis demonstrates that horizontally parallel HTS tapes could be potentially used in superconducting devices like HTS transformers, which could retain or even reduce the total average AC losses per tape with large number of parallel tapes.

    Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape. Following this procedure, her UTI completely resolved and she remained asymptomatic for several years. Seven years later she presented with a solid vaginal mass. Pelvic examination followed by transvaginal ultrasonography and magnetic resonance imaging demonstrated a large vaginal calculus located at the lower third of the anterior vaginal wall adjacent to the bladder neck. This video presents the transvaginal excision and removal of the vaginal calculus.

  6. Through the looking glass of a chemistry video game: Evaluating the effects of different MLEs presenting identical content material

    Science.gov (United States)

    Hillman, Dustin S.

    The primary goal of this study is to evaluate the effects of different media-based learning environments (MLEs) that present identical chemistry content material. This is done with four different MLEs that utilize some or all components of a chemistry-based media-based prototype video game. Examination of general chemistry student volunteers purposefully randomized to one of four different MLEs did not provide evidence that the higher the level of interactivity resulted in a more effective MLE for the chemistry content. Data suggested that the cognitive load to play the chemistry-based video game may impaired the chemistry content being presented and recalled by the students while the students watching the movie of the chemistry-based video game were able to recall the chemistry content more efficiently. Further studies in this area need to address the overall cognitive load of the different MLEs to potentially better determine what the most effective MLE may be for this chemistry content.

    In the study entitled "Web usability evaluation with screen reader users: Implementation of the Partial Concurrent Thinking Aloud technique" (Federici et al. 2010), we have proposed a modified protocol of usability evaluation technique for blind users, which integrates the features of the concurrent and the retrospective techniques. This new technique, called partial concurrent thinking aloud (PCTA), while respecting the properties of classic verbal protocols, overcomes the structural interference and the limits of concurrent and retrospective protocols when used with screen reader users. In order to facilitate understanding and acquisition of the PCTA's technique for practitioners and researchers, we have video recorded three different verbal protocols by visualizing five experimental sections. In the first two videos, we have compared a concurrent with a retrospective's verbal protocol of a sighted user, showing the difference of the verbalizations provided by the user in these two conditions. The third video shows the structural interference of the screen reader, during a blind user concurrent thinking aloud. In the last two videos, we show the difference of a blind user behaviour when PCTA or retrospective protocol is adopted. The videos clearly visualize the advantage of the PCTA use in respect of the two other protocols. In conclusion, the visualization of the PCTA technique confirms that this new verbal protocol promotes and guarantees a more user-driven usability assessment with disabled people, by better involving screen reader users, overcoming the structural interference and the limits of the concurrent and retrospective protocols.

    Relative humidity has been recognized as an important environmental factor in many head-tape interface phenomena such as headwear, friction, staining, and tape shed. Accordingly, the relative humidity is usually specified in many applications of tape use, especially when tape recorders are enclosed in hermetically sealed cases. Normally, the relative humidity is believed regulated by humidification of the fill gas to the specification relative humidity. This study demonstrates that the internal relative humidity in a sealed case is completely controlled by the time-dpendence of the hygroscopic properties of the pack of magnetic recording tape. Differences are found in the hygroscopic properties of the same brand of tape, which apparently result from aging, and which may have an effect on the long-term humidity-regulating behavior in a sealed case, and on the occurrence of head-tape interface phenomena from the long-term use of the tape. Results are presented on the basic hygroscopic properties of magnetic tape, its humidity-regulating behavior in a sealed case, and a theoretical commentary on the relative humidity dependence of head-wear by tape, is included.

    In this report we describe a computer vision based pipeline to convert in-vivo reflectance confocal microscopy (RCM) videos collected with a handheld system into large field of view (FOV) mosaics. For many applications such as imaging of hard to access lesions, intraoperative assessment of MOHS margins, or delineation of lesion margins beyond clinical borders, raster scan based mosaicing techniques have clinically significant limitations. In such cases, clinicians often capture RCM videos by freely moving a handheld microscope over the area of interest, but the resulting videos lose large-scale spatial relationships. Videomosaicking is a standard computational imaging technique to register, and stitch together consecutive frames of videos into large FOV high resolution mosaics. However, mosaicing RCM videos collected in-vivo has unique challenges: (i) tissue may deform or warp due to physical contact with the microscope objective lens, (ii) discontinuities or "jumps" between consecutive images and motion blur artifacts may occur, due to manual operation of the microscope, and (iii) optical sectioning and resolution may vary between consecutive images due to scattering and aberrations induced by changes in imaging depth and tissue morphology. We addressed these challenges by adapting or developing new algorithmic methods for videomosaicking, specifically by modeling non-rigid deformations, followed by automatically detecting discontinuities (cut locations) and, finally, applying a data-driven image stitching approach that fully preserves resolution and tissue morphologic detail without imposing arbitrary pre-defined boundaries. We will present example mosaics obtained by clinical imaging of both melanoma and non-melanoma skin cancers. The ability to combine freehand mosaicing for handheld microscopes with preserved cellular resolution will have high impact application in diverse clinical settings, including low-resource healthcare systems.

  14. In vivo multimodality video microscopy of human skin in the vertical plane (Conference Presentation)

    Reflectance confocal microscopy (RCM) and multiphoton microscopy (MPM) are non-invasive methods of acquiring morphological images of the skin in vivo. Most research in this area focuses on instruments that are configured for two-dimensional imaging in a horizontal plane parallel to the skin surface. In contrast, conventional histopathologic evaluation of the skin is based on vertical tissue sections that show microscopic features and their interrelationships according to their depth within the skin. The ability to similarly depict the skin in the vertical plane during in vivo microscopic imaging poses several significant challenges with respect to imaging speed, resolution and extractable information. Aiming to address above challenges, we developed a laser scanning multimodal microscopy system which combines RCM and MPM, and has the ability to do fast xz scanning to achieve high resolution vertical "optical sectioning" of in vivo human skin at video rates. RCM and MPM images are obtained simultaneously and co-registered thereby providing complementary morphological information. To validate the performance of this system vertical section RCM and MPM microscopic images of normal human skin in vivo were obtained at half video rates (15 frames/s). Using our system it is possible to discern the following structures: all layers of the epidermis including the stratum lucidum, the dermal-epidermal junction, and the papillary dermis. Blood flow is also visible as evidenced by blood cell movement within vessels. The effective imaging depth is about 200 micrometers. This system provides a means of interrogating human skin noninvasively at an orientation analogous to conventional histological sectioning.

    2015-12-01

    The recovery of fibre traces via tape lifting, tape scanning and manual isolation is investigated. The recovery efficiency of taping was determined using different tapes, donor textiles, and receptor textiles. It was determined that tape lifts generally recover over 90% of extraneous fibres that had been transferred by direct contact with a donor textile. The recovery via tape scanning was evaluated by the preparation of a set of 15 tapes that contained a number of target fibres on a background of other fibres. The tapes presented varying difficulty and were investigated by trained fibre examiners. The examiners were asked to locate the target fibres and to provide their opinion on the difficulty of the search. As expected, the efficiency decreases for more difficult searches. It was determined that the efficiency of the search was influenced by the microscopic illumination modes used by the examiner. A final experiment investigated the recovery by manual isolation of fibres from non-textile items. It was determined that all fibres from tie cables and knives were recovered, except in those cases where the recipient item contained many fibres. In addition, the examiners correctly sampled each of three fibre populations present on a sample of duct tape. Copyright © 2015 The Chartered Society of Forensic Sciences.

    2015-01-01

    Plantar fasciitis is considered the most common cause of foot pain. Numerous non-surgical treatments have been used to relieve symptoms. Taping is one of the most widespread treatments, with several techniques utilized in clinical practice. To evaluate, based on existing literature, the efficacy of different taping techniques in relieving symptoms and dysfunction caused by plantar fasciitis. PubMed, CINAHL, PEDro, ISIWeb of Science, and Google Scholar databases were searched from inception until December 2012, using a predefined search strategy. Controlled trials of any methodological quality were included, without any language restrictions. The methodological quality of interventional studies was evaluated inter alia by the PEDro score. Five randomized control trials, one cross-over study and two single group repeated measures studies met the inclusion criteria. Two studies were high quality; two were moderate quality and four were of poor methodological quality. All eight studies favored the use of different taping techniques. The most common technique was low dye taping. We found that in the short-term, taping is beneficial in treating plantar fasciitis. The best evidence exists for low dye taping and calcaneal taping. More research is needed to investigate long-term effect and effectiveness of specific taping techniques.

    On February 6, 1992, approximately 35 SRS personnel from DOE, WSRC, and Dames and Moore attended a very informative talk given by Dr. E.L. Albenesius who discussed the operation of the SRS Burial Ground from an historical perspective. Dr. Albenesius, a Du Point retiree, formerly served as research manager of SRL`s Environmental Effects and Solid Waste Management Technology Divisions among other assignments. One notable point Dr. Albenesius made was in answer to a question concerning what was the most important thing that could be done to reduce the hazard to man from buried waste. His response was to remove as much plutonium as practical prior to closure. In order to preserve this valuable information for the record, the program was audiotaped from which a point-by-point chronological transcription, with minor editing, was prepared.

    In this thesis work, a study on flux pinning mechanisms of commercial YBCO tapes is presented. This study has been performed via critical current characterization using transport (via direct I-V curves) and magnetization (via a Vibrating Sample Magnetometer) measurements. The latter ones turned out to be better concerning the comprehension of the pinning landscape of the provided samples, as a wider range of magnetic fields and temperatures is available for those measurements in the setup I used. The comparison of the experimental data with existing theoretical models allowed me to draw a picture of the pinning mechanisms underlying in each sample, and they turned out to be quite different one another. Moreover, for high-performance research tapes, another interesting feature has been found: the counterplay between the self-field critical current and the in-field one. Very well engineered artificial pinning structures limit the self-field critical current density due to the hi...

    Due to the considerable development of the technology of second generation high-temperature superconductors and a significant improvement in their mechanical and transport properties in the last few years it is possible to use HTS tapes in the magnetic levitation systems. The advantages of tapes on a metal substrate as compared with bulk YBCO material primarily in the strength, and the possibility of optimizing the convenience of manufacturing elements of levitation systems. In the present report presents the results of the magnetic levitation force measurements between the stack of HTS tapes containing of tapes and NdFeB permanent magnet in the FC and ZFC regimes. It was found a non- linear dependence of the levitation force from the height of the array of stack in both modes: linear growth at small thickness gives way to flattening and constant at large number of tapes in the stack. Established that the levitation force of stacks comparable to that of bulk samples. The numerical calculations using finite element method showed that without the screening of the applied field the levitation force of the bulk superconductor and the layered superconductor stack with a critical current of tapes increased by the filling factor is exactly the same, and taking into account the screening force slightly different.

    Movie presentation can act as an enrichment technique for nonhuman primates, who also show preferences for certain contents. This study investigated the video preferences and effects of movies on behavioral abnormalities in single-caged Japanese macaques. When movie rewards were provided for subjects' touch responses, the subjects maintained the touch responses during 40 2-hr sessions. Although repeated presentation of 1 stimulus set decreased the subject's touch response, changing the stimulus set led to recovery of this response. The subjects showed clear preferences, consistent across 2 different stimulus sets, for movies showing humans or animation (61.1% of total duration). Subjects consistently played movies both with and without their preferred content. The availability of a variety of contents might be important for attracting subjects' interest. The frequency with which monkeys engaged in abnormal behaviors decreased in the experimental (20.9%) and the postexperimental (25.6%) periods compared with the preexperimental period (33.5%). Movie presentations could keep attracting the interest of single-caged monkeys in their visual environment, ameliorating their behavioral abnormalities for some time. In summary, social experience during infancy might influence Japanese macaques' movie preferences. Copyright © Taylor & Francis Group, LLC

  9. Paper Punch Tape

    CERN Multimedia

    Physicists coded and recorded their programs through series of holes on punch paper tape or on punched cards. It was popular in the 1970s due to its high throughput speed and low cost, paper tape was one of the original data storage methods for computers. Information was encoded in the distinct pattern of holes punched in the paper; the paper itself was oiled to facilitate being run through the reading mechanism and to prevent tears due to brittleness. Though the paper was cheap, it had low storage capacity (only a few dozen kilobytes per roll) and the machinery involved in punching the holes was quite expensive. Higher capacity alternatives, such as magnetic tape, has get developped.

    This experiment examined the effects of exposure to physique-salient (PS) and physique non-salient (PNS) exercise videos and the moderating influence of perceived physique discrepancies, on body image, self-presentational concerns, and exercise motivation. Eighty inactive women (M age=26) exercised to a 30 min instructional exercise video. In the PS condition, the video instructor wore revealing attire that emphasized her thin and toned physique. In the PNS condition, she wore attire that concealed her physique. Participants completed pre- and post-exercise measures of body image, social physique anxiety (SPA) and self-presentational efficacy (SPE) and a post-exercise measure of exercise motivation and perceived discrepancies with the instructor's body. No main or moderated effects emerged for video condition. However, greater perceived negative discrepancies were associated with poorer post-exercise body satisfaction and body evaluations, and higher state SPA. There were no effects on SPE or motivation. Results suggest that exercise videos that elicit perceived negative discrepancies can be detrimental to women's body images.

    The tape casting method has kept its interest over the years due to the wide spectrum of its applications and its economic viability in comparison to other techniques focused on micrometric thin films. Two key parameters for tape casting are the binder relative amount and the Dr. Blade gap. The binder relative amount has a strong influence on the rheological properties for the ceramic YSZ slurry (ethanol, butanone, TEA, PVB, PEG, DEP). The coefficient K and the exponent m of the Cross model are reported to be inside the ranges 152.25-231.12 and 0.00987-0.26646 for PVB binder weight percentage concentrations between 6% and 12%. It is possible to describe the ceramic tape thickness dependence by means of a linear relation depending on the Dr. Blade gap whose linear coefficients (slope) are equal to 0.0350 and 0.2171 for green and sintered tapes respectively, with the YSZ slurry of the present work.

    As medical students become residents, teaching becomes an expected and integral responsibility. Yet, training-for-teaching opportunities are lacking. In 2014, the authors designed a pilot study using rubric-guided, focused, personalized coaching sessions and video-recorded presentations to improve student teaching skills among fourth-year students at Harvard Medical School. In 2014-2015, the authors recruited students from an elective on how to tutor preclinical students for the pilot, which consisted of four phases: a precoaching teaching presentation, a 30- to 45-minute coaching session, a postcoaching teaching presentation, and blinded reviewer ratings. Students' pre- and postcoaching presentations were video recorded. Using a scoring rubric for 15 teaching skills, students rated their pre- and postcoaching videos. Blinded reviewers also rated the pre- and postcoaching presentations using the same rubric with an additional category to gauge their overall impression. Fourteen students completed all four phases of the pilot. Students' ratings demonstrated statistically significant improvement in several teaching skills, including presentation content (P rubric, using coaching in different teaching settings, addressing the interventions' generalizability, training coaches, and performing additional evaluations.

    2008-02-01

    A tape casting procedure for fabricating ceramic magnesium oxide tapes has been developed as a method to produce flat sheets of sintered MgO that are thin and porous. Thickness of single layer tapes is in the range of 200-400 {micro}m with corresponding surface roughness values in the range of 10-20 {micro}m as measured by laser profilometry. Development of the tape casting technique required optimization of pretreatment for the starting magnesium oxide (MgO) powder as well as a detailed study of the casting slurry preparation and subsequent heat treatments for sintering and final tape flattening. Milling time of the ceramic powder, plasticizer, and binder mixture was identified as a primary factor affecting surface morphology of the tapes. In general, longer milling times resulted in green tapes with a noticeably smoother surface. This work demonstrates that meticulous control of the entire tape casting operation is necessary to obtain high-quality MgO tapes.

  20. Equilibrium states and stability of pre-tensioned adhesive tapes

    Full Text Available In the present paper we propose a generalization of the model developed in Afferrante, L.; Carbone, G.; Demelio, G.; Pugno, N. Tribol. Lett. 2013, 52, 439–447 to take into account the effect of the pre-tension in the tape. A detailed analysis of the peeling process shows the existence of two possible detachment regimes: one being stable and the other being unstable, depending on the initial configuration of the tape. In the stability region, as the peeling process advances, the peeling angle reaches a limiting value, which only depends on the geometry, on the elastic modulus of the tape and on the surface energy of adhesion. Vice versa, in the unstable region, depending on the initial conditions of the system, the tape can evolve towards a state of complete detachment or fail before reaching a state of equilibrium with complete adhesion. We find that the presence of pre-tension in the tape does not modify the stability behavior of the system, but significantly affects the pull-off force which can be sustained by the tape before complete detachment. Moreover, above a critical value of the pre-tension, which depends on the surface energy of adhesion, the tape will tend to spontaneously detach from the substrate. In this case, an external force is necessary to avoid spontaneous detachment and make the tape adhering to the substrate.

  4. Carbon Nanotube-Based Synthetic Gecko Tapes

    2008-03-01

    Wall-climbing geckos have unique ability to attach to different surfaces without the use of any viscoelastic glues. On coming in contact with any surface, the micron-size gecko foot-hairs deform, enabling molecular contact over large areas, thus translating weak van der Waals (vdW) interactions into enormous shear forces. We will present our recent results on the development of synthetic gecko tape using aligned carbon nanotubes to mimic the keratin hairs found on gecko feet. The patterned carbon nanotube-based gecko tape can support a shear stress (36 N/cm^2) nearly four times higher than the gecko foot and sticks to a variety of surfaces, including Teflon. Both the micron-size setae (replicated by nanotube bundles) and nanometer-size spatulas (individual nanotubes) are necessary to achieve macroscopic shear adhesion and to translate the weak vdW interactions into high shear forces. The carbon nanotube based tape offers an excellent synthetic option as a dry conductive reversible adhesive in microelectronics, robotics and space applications. The mechanism behind these large shear forces and self-cleaning properties of these carbon nanotube based synthetic gecko tapes will be discussed. This work was performed in collaboration with graduate students Liehui Ge, and Sunny Sethi, and collaborators from RPI; Lijie Ci and Professor Pulickel Ajayan.

  5. Are there Nonverbal Cues to Commitment? An Exploratory Study Using the Zero-Acquaintance Video Presentation Paradigm

    Full Text Available Altruism is difficult to explain evolutionarily if subtle cheaters exist in a population (Trivers, 1971. A pathway to the evolutionary maintenance of cooperation is nonverbal altruist-detection. One adaptive advantage of nonverbal altruist-detection is the formation of trustworthy division of labour partnerships (Frank, 1988. Three studies were designed to test a fundamental assumption behind altruistic partner preference models. In the first experiment perceivers (blind with respect to target altruism level made assessments of video-clips depicting self-reported altruists and self-reported non-altruists. Video-clips were designed with attempts to control for attractiveness, expressiveness, role-playing ability, and verbal content. Overall perceivers rated altruists as more “helpful” than non-altruists. In a second experiment manipulating the payoffs for cooperation, perceivers (blind with respect to payoff condition and altruism level assessed altruists who were helping others as more “concerned” and “attentive” than non-altruists. However perceivers assessed the same altruists as less “concerned” and “attentive” than non-altruists when the payoffs were for self. This finding suggests that perceivers are sensitive to nonverbal indicators of selfishness. Indeed the self-reported non-altruists were more likely than self-reported altruists to retain resources for themselves in an objective measure of cooperative tendencies (i.e. a dictator game. In a third study altruists and non-altruists' facial expressions were analyzed. The smile emerged as a consistent cue to altruism. In addition, altruists exhibited more expressions that are under involuntary control (e.g., orbicularis oculi compared to non-altruists. Findings suggest that likelihood to cooperate is signaled nonverbally and the putative cues may be under involuntary control as predicted by Frank (1988.

  6. Enhancing the low-level tape layer of CERN Tape Archive software

    CERN Document Server

    AUTHOR|(CDS)2160814; Ruse, Laura Cristina; Vasilescu, Laura

    CERN manages the largest scientific data archive in the HEP domain. The archive currently holds over 180 Petabytes, with forecasts of up to 100PB of new data added per year. Considering this numbers, the most cost-effective solution for storage in terms of capacity and maintenance is represented by magnetic tapes. The drawback of this solution is the access time which can raise to several minutes for a series of files. In an environment where very large volumes of physics data are being traded from tape to disk and vice versa, this issue becomes a serious performance bottleneck. This thesis introduces two low-level tape access optimizations: first, adding support for the Recommended Access Order (RAO), a mechanism offered by the tape hardware infrastructure to compute the file order corresponding to the minimum access time. We will present our solution for including RAO in the file retrieval operations in CERN tape archive software in order to benefit from the reduced reading time. The second optimization ...

    Full Text Available Background: Sports participation is considered a meaningful occupation for people of all ages. Multiple disciplines use Kinesio Tape® during treatment (Kinesio Taping® Association International, 2013e for sportsrelated injuries. While the use of Kinesio Tape® is becoming increasingly popular in sports, there is a lack of evidence supporting its effectiveness. The purpose of this study was to address the following question: Is there a perceived sports performance benefit of using Kinesio Tape® compared to non-kinesiology tape or no tape in healthy collegiate athletes? Method: This quantitative pilot study used a convenience sampling method. The participants included eighteen healthy men’s and women’s lacrosse players from a division III university. A crossover design was used and consisted of three trials: Kinesio Tape®, non-kinesiology tape, and no tape. Perceived sports performance was measured using an 8-item, study-specific questionnaire. Results: The results indicated that there were no significant differences between the Kinesio Tape® and no tape trials. There were statistically significant differences found between the non-kinesiology tape and no tape trials. Conclusion: While non-kinesiology tape was the only tape that yielded significant differences, the participants perceived their sports performance to be better when wearing either non-kinesiology tape or KT than when wearing no tape, indicating a possible placebo effect.

    Full Text Available After a nearly four-decade career, Madonna has not stopped with a modernist/postmodernist strategy of shock, which provides the reader or viewer the possibility of different interpretations of her art. While some art theorists condemn her as a ‘total antifeminist’, others praise Madonna’s work and point out her feminist side, through which she represents the ideal of a strong, independent and successful womanconfirming her own power and sexuality. Breaking conventional stereotypes through her videos and concert performances, the ‘Queen of Pop’ constantly demonstrates sexual dominance over both genders. In this paper, based on the contemporary research of Douglas Kellner and other theorists, I will analyze music videos and live performances from the 1990suntil the recent video for the song Bitch, I’m Madonna and consider why Madonna can be interpreted in two ways – as someone who ‘undermines her own feminism’ or as someone who is transparently presented as a feminist in the world of pop culture.

The appointed subject for the very first one of them was Radio and the invited scholar, Eduardo Vicente, professor at the Graduate Course in Audiovisual and at the Postgraduate Program in Audiovisual Media and Processes of the School of Communication and Arts of the University of São Paulo (ECA-USP. Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”. Andrew Dubber (Birmingham City University regarding the challenges posed by a Digital Era argues for a theoretical approach in radio studies which can consider a Media Ecology.

    Over 100 Petabytes of data is stored on several kind of physical support, namely disks and tapes. Data on any physical support or traveling on a data link (network, fibre channel...) can be subject to silent data corruption. A possible improvement is introducing end-to-end data integrity from the filesystem down to the tape layer. For the tape back-end it can be done by using Logical Block Protection, which computes and compares CRC checksum of every single block of data. During my work, I improved on-the-fly CRC calculation for the tape storage system, which was achieved by introducing a multithreaded implementation - a technique applicable to arbitrary CRC algorithm.

    Ruddick, Andrew J.

    1993-01-01

    At the 1991 Conference on Mass Storage Systems and Technologies, ICI Imagedata presented a paper which introduced ICI Optical Data Storage Tape. This paper placed specific emphasis on the media characteristics and initial data was presented which illustrated the archival stability of the media. More exhaustive analysis that was carried out on the chemical stability of the media is covered. Equally important, it also addresses archive management issues associated with, for example, the benefits of reduced rewind requirements to accommodate tape relaxation effects that result from careful tribology control in ICI Optical Tape media. ICI Optical Tape media was designed to meet the most demanding requirements of archival mass storage. It is envisaged that the volumetric data capacity, long term stability and low maintenance characteristics demonstrated will have major benefits in increasing reliability and reducing the costs associated with archival storage of large data volumes.

    Visual forms of instruction are increasingly used as a result of the widespread use of video technologies such as broadcasts, teleconferencing, tapes, videodiscs, and emerging multimedia combinations of computer and digital video technologies. The considerable amount of research that stretches back to early work with film, television, and static visual materials can be of benefit in developing these new forms of instruction. The objective is to present a review of the current research literature regarding the use of dynamic video media in instruction. Research on the following topics was reviewed: general reviews of the effectiveness, acceptance, and costs of several forms of educational television; teaching techniques used effectively with video media; combining visual and verbal information; the effects of motion, animation, and interactivity, the relationship between media perceptions and learning; the effect of various video production techniques on learning; and critical perspectives on learning from media. This review can be used as background material for future research or instructional development efforts concerned with learning from video-based media.

    Callaghan, Michael J; Selfe, James

    2012-04-18

    Patellofemoral pain syndrome refers to the clinical presentation of knee pain related to changes in the patellofemoral joint. Patellofemoral pain syndrome usually has a gradual onset of pain with none of the features associated with other knee diseases or trauma. It is often treated by physiotherapists, who use a variety of techniques including patellar taping. This involves the application of adhesive sports medical tape applied directly to the skin over the patella on the front of the knee. Patients often report an instantaneous improvement in pain and function after the tape is applied, but its longer term effects are uncertain. The objective was to assess the effects, primarily on pain and function, of patellar taping for treating patellofemoral pain syndrome in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, EMBASE, PEDro, SPORTDiscus, AMED, reference lists of articles, trial registers and conference proceedings. All were searched to August 2011. Randomised controlled trials and quasi-randomised controlled trials testing the effects of patellar taping on clinically relevant outcomes, pain and function, in adults with patellofemoral pain syndrome. We excluded studies testing only the immediate effects of tape application. Both review authors independently performed study selection, data extraction and assessment of risk of bias. Trialists were contacted for more information. Data were pooled where possible. Five small heterogeneous randomised controlled trials, all at high risk of performance bias and most at risk of at least one other type of bias, were included. These involved approximately 200 participants with a diagnosis of patellofemoral pain syndrome. All compared taping versus control (no or placebo taping) and all included one or more co-interventions given to both taping and control group participants; this was prescribed exercise in four

    At present, tape media are mainly used for video recording globally. However, in the near future, disc media will come into general use, as they possess many strong points compared with tape media. Thus, we are now researching the development of a high-definition digital video disc recorder with high capacity, high data transfer rate, and low cost. Our target specifications are 15 GB to 18 GB, and over 35 Mbps, using a 120 mm phase change disc and a blue-laser diode. To confirm that it is possible, numerous sample discs were manufactured and experiments were carried out. We succeeded in obtaining good experimental results. In this study, we demonstrate the possibility of realizing a high-definition digital video disc recorder using a 120 mm phase change disc and a blue-laser diode without using a disc cartridge or any extraordinary method that increases the cost.

    2017-04-01

    Cabon fibre composites are used where mechanical performance such as strength, stiffness and impact properties at low density is a critical parameter for engineering applications. Carbon fibre flat tape is one material which is traditionally used to manufacture three-dimensional composites in this area. Modifying the carbon fibre tape to incorporate other functions such as stealth, electromagnetic interference, shielding, de-icing, self-repair, energy storage, allows us to create multi-functional carbon fibre tape. Researchers have been developing such material and the technology for their manufacture in order to produce multifunctional carbon fibre based components more economically and efficiently. This paper presents the manufacturing process of a metallised carbon fibre material for a chopped fibre preforming process that uses electromagnets for preforming instead of traditional suction airflow fibre deposition. In addition, the paper further presents mechanical and magneto-static modelling that is carried out to investigate the bending properties of the material produced and its suitability for creating 3D preforms.

    The forthcoming introduction of helical scan digital data tape recorders with high access bandwidth and large capacity will facilitate the recording and retrieval of a wide variety of multimedia information from different sources, such as computer data and digital audio and video. For the compression of digital audio and video, the MPEG standard has internationally been accepted. Although helical scan tape recorders can store and playback MPEG compressed signals transparently they are not well suited for carrying out special playback modes, in particular fast forward and fast reverse. Only random portions of a original MPEG bitstream are recovered on fast playback. Unfortunately these shreds of information cannot be interpreted by a standard MPEG decoder, due to loss of synchronization and missing reference pictures. In the EC-sponsored RACE project DART (Digital Data Recorder Terminal) the possibilities for recording and fast playback of MPEG video on a helical scan recorder have been investigated. In the approach we present in this paper, we assume that not transcoding is carried out on the incoming bitstream at recording time, nor that any additional information is recorded. To use the shreds of information for the reconstruction of interpretable pictures, a bitstream validator has been developed to achieve conformance to the MPEG-2 syntax during fast playback. The concept has been validated by realizing hardware demonstrators that connect to a prototype helical scan digital data tape recorder.

    1991-01-01

    Very high coercivity metal particle (MP) and metal evaporated (ME) tapes are being used in 8mm video and digital audio tape applications, and more recently in digital data recording applications. In view of the inherent susceptibility of such media to environmental corrosion, a number of recent studies have addressed their long term stability and archivability. These studies have used an accelerated corrosion test based either on elevated temperature-humidity or polluting gas atmospheres known as Battelle tests. A comparison of the Battelle test results performed at different laboratories reveals a large variation from one location to another, presumably due to incorrect replication of the Battelle condition. Furthermore, when the Battelle tests are performed on enclosed cartridges, it is quite possible that diffusion limits the penetration of the extremely low concentration polluting gaseous species to the inner layers of the tapes during the short time of the accelerated test, whereas in real life these diffusion limitations may not apply. To avoid this uncertainty, the corrosion behavior of commercial 8mm MP and ME tapes when cassettes without their external plastic cases were exposed to 50 deg C and 80 percent RH for 7.5 weeks is investigated.

    While Bi-2223 tapes have been the workhorses of the superconductor industry, their poor performance in applied magnetic fields restrict their use to below 30 K. Melt-processing of Ag-clad Yb-123 PIT tapes offers a simple and scalable technique for fabricating long-length HTS conductors capable of being used at 77 K. Under reduced oxygen partial pressure, the peritectic temperature of Yb-123 is below the melting point of Ag, and this facilitates the adaptation of melt-texturing methods for fabricating these tapes. The effect of melt-processing temperature on current density was also explored; a temperature of 965 C yielded optimal critical current values. The critical current density achieved at 4.2 K was 20,000 A/cm{sup 2}, corresponding to a critical current of 52 A. Based on the above results, an optimal processing zone for melt-processing of Ag-clad Yb-123 tapes was determined. These results hold promise for melt-processing of Ag-clad Yb-123 tapes as an alternative to Bi-2223 PIT technology.

    The AC loss measurements of the high temperature superconductor (HTS) cable prototype in the EDIPO test facility motivated detailed investigations of the loss contributions from the tape, strand and cable stages of the HTS fusion conductor design proposed at the Swiss Plasma Center. As an initial step of the task, magnetization tests of soldered stacks of HTS tapes were carried out at temperatures of 5 and 77 {{K}} and magnetic fields up to 12 {{T}} using the vibrating sample magnetometer technique. The influence on the magnetization loss of the number of tapes, width of the tape, field’s orientation and tape’s manufacturer is studied experimentally performing both the major and minor magnetization loops with different ramp rates of the applied magnetic field. In order to validate the test results, a numerical model is developed and presented in this work. From the numerical model we also deduced an analytical approach for the magnetization loss in the stacks of tapes with arbitrary number of tapes in the critical state model. Comparison between the measured and estimated magnetization loss of the cable prototypes is reported as well.

    Full Text Available In this paper, the experimental heat transfer, friction loss and thermal performance data for water flowing through the absorber tube fitted with two different twisted tape configurations in parabolic trough collector (PTC are presented. In the present work, a relative experimental study is carried out to investigate the performance of a PTC influenced by heat transfer through fluidabsorber wall mixing mechanism. The major findings of this experiment show that heat transport enhancement in the nail twisted tape collector perform significantly better than plain twisted tapes and also show that the smallest twisted tape ratio enhances the system performance remarkably maximizing the collector efficiency. The results suggest that the twisted tape and nail twisted tape would be a better option for high thermal energy collection in laminar region of the PTC system.

  11. Tactile stimulation with kinesiology tape alleviates muscle weakness attributable to attenuation of Ia afferents.

    Konishi, Yu

    2013-01-01

    Prolonged vibration stimulation to normal individuals could lead to muscle weakness attributable to attenuation of afferent feedback. This weakness is neurophysiologically similar to that seen in patients with knee injury. Theoretically, increasing input to gamma motor neurons could reverse this weakness. Sensory input to these neurons from skin could indirectly increase Ia afferent feedback. The present study examined the effect of this tactile stimulation in the form of Kinesiology tape on muscle weakness attributable to attenuation of afferent feedback. Randomized, crossover design. All participants were measured their eccentric maximal voluntary contractions under the 2 conditions (taping and non-taping). First, maximal voluntary contraction during eccentric contraction was measured as baseline. For the taping condition, Kinesiology tape was applied around each subject's knee joint during maximal voluntary contraction measurement after vibration. For the non-taping condition, tape was not applied during maximal voluntary contraction measurement after vibration. Mean percentage changes between pre- and post-vibration stimulation were compared between two conditions. Maximal voluntary contraction and average electromyography of taping condition was significantly larger than that of non-taping condition. Our results suggest that tactile stimulation in the form of Kinesiology tape inhibits the decline of both strength and electromyography. Alpha motor neuron activity attenuated by prolonged vibration would thus be partially rescued by tactile stimulation. These results indirectly suggest that stimulation of skin around the knee could counter quadriceps femoris weakness due to attenuated Ia afferent activity. Copyright © 2012 Sports Medicine Australia.

    During recent years scientific research has demonstrated a growing interest in elastic and anaelastics adhesive taping techniques. However, only a few studies investigating the principles behind the effects of taping. At present, the action mechanisms of kinesiology taping remain speculative. To investigate the effects of taping application on the tone of the pectoralis major muscle at rest, in absence of any relevant pathologies. The study involved a prospective, randomised and blinded clinical trial on healthy individuals and a repeated measures study design. Two different taping techniques (facilitatory and inhibitory) were applied over the pectoralis major of 24 healthy volunteers. The outcome measure was passive range of motion of external rotation of the glenohumeral joint. Facilitatory taping significatively enhanced the activity of the underlying muscle. Results showed a negative correlation between facilitatory taping application and the contralateral pectoralis major length, indicating a possible effect on the muscle tone of areas outside the site of direct application. The inhibitory taping application did not produce significant results. effects on ipsilateral and contralateral muscle physiology could be interpreted through the initial hypothesis of taping inducing changes in fascial stiffness. These could be transmitted along the continuing system. Further studies are needed to inform the possible uses of taping in clinical practice. Crown Copyright © 2013. Published by Elsevier Ltd.

  13. Experimental Study on Ferromagnetic Shunt Effects on the Critical Current of BSCCO Tape in Stacked Conductors

    2017-01-01

    Full Text Available In the 200 m high temperature superconducting (HTS cable test facility at Chubu University constructed in 2010, a three-layer structure of the tapes in the cable is employed for obtaining the high current capacity up to 2 kA. Previous study shows that the critical current is affected by the layout of the tapes such as gaps and the current feeding mode. In the stacked tape conductors, the critical current of BSCCO tapes shows strong dependence on the current feeding directions between the tapes. The critical current is improved when the opposite-direction current is applied to them and degraded for the same-direction current feeding mode because of strong magnetic field interaction between them from the transport current in each tape. This paper presents the measurements of the critical currents of a BSCCO tape in the stacked conductors with the ferromagnetic materials. By using the ferromagnetic materials surrounding the tapes, self-field of HTS tapes is affected and their critical currents are improved by more than 10%. Ferromagnetic shunt effects on the critical current of HTS tape are reported through the magnetic field analysis.

  15. Transmission of compressed video

    1990-09-01

    An overview of video coding is presented. The aim is not to give a technical summary of possible coding techniques, but to address subjects related to video compression in general and to the transmission of compressed video in more detail. Bit rate reduction is in general possible by removing redundant information; removing information the eye does not use anyway; and reducing the quality of the video. The codecs which are used for reducing the bit rate, can be divided into two groups: Constant Bit rate Codecs (CBC's), which keep the bit rate constant, but vary the video quality; and Variable Bit rate Codecs (VBC's), which keep the video quality constant by varying the bit rate. VBC's can be in general reach a higher video quality than CBC's using less bandwidth, but need a transmission system that allows the bandwidth of a connection to fluctuate in time. The current and the next generation of the PSTN does not allow this; ATM might. There are several factors which influence the quality of video: the bit error rate of the transmission channel, slip rate, packet loss rate/packet insertion rate, end-to-end delay, phase shift between voice and video, and bit rate. Based on the bit rate of the coded video, the following classification of coded video can be made: High Definition Television (HDTV); Broadcast Quality Television (BQTV); video conferencing; and video telephony. The properties of these classes are given. The video conferencing and video telephony equipment available now and in the next few years can be divided into three categories: conforming to 1984 CCITT standard for video conferencing; conforming to 1988 CCITT standard; and conforming to no standard.

  19. A numerical study on helical vortices induced by a short twisted tape in a circular pipe

    Directory of Open Access Journals (Sweden)

    Wen Liu

    2015-03-01

    Full Text Available Helical vortices, as one kind of secondary flows, are recently observed downstream of the short twisted tape. The behaviors of vortices, which have significant effects on the efficiency of twisted tape, are not well understood. As such, the formation and development of helical vortices induced by the short twisted tape are studied numerically. The results show that two symmetrical stable helical vortices are present downstream of the twisted tape. The values of radial velocities cannot be neglected due to the presence of the vortices. The vortices form in the twisted tape and remain the structure downstream of the twisted tape. Torsion promotes the formation of helical vortices. The intensities of helical vortices decay along the streamwise direction. With the increasing Reynolds numbers, the intensities of helical vortices increase, and the trend is in agreement with the swirl intensities. The intensities of helical vortices decay slowly compared with the intensities of swirling flow.

    Traditionally, hallux valgus operative correction has been accompanied by serial spica taping of the great toe during the postoperative period. We retrospectively reviewed 187 adult patients who underwent proximal first metatarsal osteotomy with a modified McBride procedure in 2008-2009 (n = 83) and 2011-2012 (n = 104). Postoperatively, to maintain the corrected position of the hallux, patients from 2008 through 2009 underwent weekly spica taping, while patients from 2011 through 2012 utilized a toe separator. The hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured using anteroposterior weight-bearing preoperative, 2-week postoperative non-weight-bearing, and 3-month weight-bearing final follow-up radiographs. A mixed-effects linear regression model identified differences between the treatment groups over time, and a t test compared actual radiographic differences at final follow-up. The mixed-effects model revealed no significant difference in the HVA over time when comparing patients taped to those not taped at the preoperative (33 ± 6 vs 33 ± 6), 2-week postoperative (10 ± 7 vs 9 ± 6), and 3-month follow-up (14 ± 6 vs 11 ± 7) visits (P = .08). At final follow-up, the HVA was lower for the group that was not taped, but the difference (2.5 degrees) was below the minimal clinically important difference (MCID) (P = .015, 95% CI 0.5-4.5). For IMA, there was improved maintenance of correction over time in the patients that were not taped compared to those taped at the preoperative (15 ± 3 vs 15 ± 3), 2-week postoperative (2 ± 2 vs 3 ± 3), and 3-month follow-up (5 ± 4 vs 7 ± 4) visits (P = .002). At final follow-up, the IMA was lower for the group that was not taped, but the difference (1.7 degrees) was below the MCID (P = .004, 95% CI 0.7-2.9). We report no radiographic benefit of postoperative taping after hallux valgus correction. The present study challenges the previous dogma of postoperative spica taping as the protocol is cost and

    2014-03-21

    We investigate the generation of the screeching sound commonly heard during tape peeling using synchronised high-speed video and audio acquisition. We determine the peak frequencies in the audio spectrum and, in addition to a peak frequency at the upper end of the audible range (around 20 kHz), we find an unexpected strong sound with a high-frequency far above the audible range, typically around 50 kHz. Using the corresponding video data, the origins of the key frequencies are confirmed as being due to the substructure "fracture" bands, which we herein observe in both high-speed continuous peeling motions and in the slip phases for stick-slip peeling motions.

    1992-01-01

    The success of Thailand's 1985 malaria education cassette tapes project motivated the Highland Development Program to produce tapes in 6 tribal languages on family planning, maternal and child health, nutrition, and disease prevention. Staff produced tapes using a drama or radio magazine format as a series of short features with music and sound effects. Scriptwriters consulted villagers, broadcasting professionals, research workers, and health officials to tailor messages to the various hill tribes. They tried to avoid conflict between traditional and modern concepts and to minimize distrust of government services. The scriptwriters used basically short, grammatically simple sentences, and colloquial Thai to simplify translation. The staff tried to recruit literate, adult, native speakers of the target languages with some experience in health education in their own languages. Obstacles encountered with translation included some languages used an uncommon alphabet or translators did not know their own alphabet. The program backtranslated the scripts to assure the accuracy of the messages and the appropriateness of the words used. Backtranslation revealed deficiencies in the translated messages. Altering the meaning of technical terms tended to be simple mistakes, words with multiple meanings, and exaggeration of problems and/or solutions. Translators also sometimes failed to adapt cultural ideas to those of their tribes. For example, some persons translated all possible misconceptions about a disease yet the tribes did not have all the misconceptions. As of early 1992, recording, pretesting, distribution, and follow up had not yet taken place. The staff should meet with a recording studio to coordinate production including technicians and translators identifying means to communicate. Staff should be aware of signs of poor translation which they may have missed earlier and surfaces during recording. Pretesting should occur among literate and illiterate members of

  8. Digital terrain tapes: user guide

    1980-01-01

    DMATC's digital terrain tapes are a by-product of the agency's efforts to streamline the production of raised-relief maps. In the early 1960's DMATC developed the Digital Graphics Recorder (DGR) system that introduced new digitizing techniques and processing methods into the field of three-dimensional mapping. The DGR system consisted of an automatic digitizing table and a computer system that recorded a grid of terrain elevations from traces of the contour lines on standard topographic maps. A sequence of computer accuracy checks was performed and then the elevations of grid points not intersected by contour lines were interpolated. The DGR system produced computer magnetic tapes which controlled the carving of plaster forms used to mold raised-relief maps. It was realized almost immediately that this relatively simple tool for carving plaster molds had enormous potential for storing, manipulating, and selectively displaying (either graphically or numerically) a vast number of terrain elevations. As the demand for the digital terrain tapes increased, DMATC began developing increasingly advanced digitizing systems and now operates the Digital Topographic Data Collection System (DTDCS). With DTDCS, two types of data elevations as contour lines and points, and stream and ridge lines are sorted, matched, and resorted to obtain a grid of elevation values for every 0.01 inch on each map (approximately 200 feet on the ground). Undefined points on the grid are found by either linear or or planar interpolation.

    We have measured a number of tapes, coils, and magnets produced by commercial vendors and determined their properties as functions of magnetic field and temperature. The tapes were measured at the National High Magnetic Field Laboratory in magnetic fields to 20 tesla and at temperatures of 4.2 K, 27 K, 65 K, and 77 K. For the tapes we report critical currents and current-voltage characteristics. Six inch diameter coils were measured at NRL in zero magnetic field. Critical currents, current-voltage characteristics, and reliability studies are reported for the coils. Larger 10 inch diameter coils, which are to be used in a 200 hp superconducting motor, were also measured and results will be presented. The talk will also review the status of the most recent tests of the superconducting motor.

  11. Stick-slip substructure in rapid tape peeling

    KAUST Repository

    Thoroddsen, Sigurdur T.

    2010-10-15

    The peeling of adhesive tape is known to proceed with a stick-slip mechanism and produces a characteristic ripping sound. The peeling also produces light and when peeled in a vacuum, even X-rays have been observed, whose emissions are correlated with the slip events. Here we present direct imaging of the detachment zone when Scotch tape is peeled off at high speed from a solid surface, revealing a highly regular substructure, during the slip phase. The typical 4-mm-long slip region has a regular substructure of transverse 220 μm wide slip bands, which fracture sideways at speeds over 300 m/s. The fracture tip emits waves into the detached section of the tape at ∼100 m/s, which promotes the sound, so characteristic of this phenomenon.

    2017-07-01

    Non specific lower back pain is a common musculoskeletal disorder in manual labourers due to the strenuous nature of their job. Fear of pain can cause restrictions in trunk movement leading to reduced flexibility. Kinesiology Tape (KT) may be an option for treating low back stiffness. The present study investigated the immediate effect of KT on trunk flexion active range of motion. 34 male participants (mean age ± SD: 42 ± 11), in physically demanding jobs, asymptomatic of pain, with a history of non specific lower back pain were randomly assigned to: 1) KT Intervention (KTI) or 2) KT Placebo (KTP). Trunk flexion data was collected at baseline and immediately following tape application. ANCOVA was used to examine the differences between groups. The KTI group demonstrated a statistically significant gain in Trunk flexion compared with baseline (2.75 cm, P < 0.05). Changes from pre to post treatment for the KTP were not significant (1.57 cm, P = 0.062). No statistically significant differences existed between groups post-treatment (P = 0.218). KTI demonstrates an immediate positive effect on trunk flexion when compared with baseline measurements. However, results suggest that KTI performs no better than a comparable placebo.

    2012-11-01

    Full Text Available As academics we study, research and teach audiovisual media, yet rarely disseminate and mediate through it. Today, developments in production technologies have enabled academic researchers to create videos and mediate audiovisually. In academia it is taken for granted that everyone can write a text. Is it now time to assume that everyone can make a video essay? Using the online journal of academic videos Audiovisual Thinking and the videos published in it as a case study, this article seeks to reflect on the emergence and legacy of academic audiovisual dissemination. Anchoring academic video and audiovisual dissemination of knowledge in two critical traditions, documentary theory and semiotics, we will argue that academic video is in fact already present in a variety of academic disciplines, and that academic audiovisual essays are bringing trends and developments that have long been part of academic discourse to their logical conclusion.

    We propose an easy-to-construct digital video editing system ideal to produce video documentation and still images. A digital video editing system applicable to many video sources in the operating room is described in detail. The proposed system has proved easy to use and permits one to obtain videography quickly and easily. Mixing different streams of video input from all the devices in use in the operating room, the application of filters and effects produces a final, professional end-product. Recording on a DVD provides an inexpensive, portable and easy-to-use medium to store or re-edit or tape at a later time. From stored videography it is easy to extract high-quality, still images useful for teaching, presentations and publications. In conclusion digital videography and still photography can easily be recorded by the proposed system, producing high-quality video recording. The use of firewire ports provides good compatibility with next-generation hardware and software. The high standard of quality makes the proposed system one of the lowest priced products available today.

  5. Effects of low-dye taping on plantar pressure pre and post exercise: an exploratory study.

    LENUS (Irish Health Repository)

    Nolan, Damien

    2009-01-01

    BACKGROUND: Low-Dye taping is used for excessive pronation at the subtalar joint of the foot. Previous research has focused on the tape\\'s immediate effect on plantar pressure. Its effectiveness following exercise has not been investigated. Peak plantar pressure distribution provides an indirect representation of subtalar joint kinematics. The objectives of the study were 1) To determine the effects of Low-Dye taping on peak plantar pressure immediately post-application. 2) To determine whether any initial effects are maintained following exercise. METHODS: 12 asymptomatic subjects participated; each being screened for excessive pronation (navicular drop > 10 mm). Plantar pressure data was recorded, using the F-scan, at four intervals during the testing session: un-taped, baseline-taped, post-exercise session 1, and post-exercise session 2. Each exercise session consisted of a 10-minute walk at a normal pace. The foot was divided into 6 regions during data analysis. Repeated-measures analysis of variance (ANOVA) was used to assess regional pressure variations across the four testing conditions. RESULTS: Reduced lateral forefoot peak plantar pressure was the only significant difference immediately post tape application (p = 0.039). This effect was lost after 10 minutes of exercise (p = 0.036). Each exercise session resulted in significantly higher medial forefoot peak pressure compared to un-taped; (p = 0.015) and (p = 0.014) respectively, and baseline-taped; (p = 0.036) and (p = 0.015) respectively. Medial and lateral rearfoot values had also increased after the second session (p = 0.004), following their non-significant reduction at baseline-taped. A trend towards a medial-to-lateral shift in pressure present in the midfoot immediately following tape application was still present after 20 minutes of exercise. CONCLUSION: Low-Dye tape\\'s initial effect of reduced lateral forefoot peak plantar pressure was lost after a 10-minute walk. However, the tape continued

    Cross-sectional laboratory study. The aim of the present study was to evaluate and compare the mechanical properties of different therapeutic elastic tapes used in sports and clinical practice. Therapeutic tapes have been used since around the 1800s. They are composed of cotton, elastic filaments and adhesive glue that provides an effect of tactile and mechanical stimulation. However, as taping has evolved, manufacturers have implemented new materials and claim that the tensile properties and adhesion of tapes contribute more significantly in the rehabilitation process. Fifty samples of elastic tapes (5 different manufacturers; 10 samples from each manufacturer) were submitted to longitudinal traction until rupture as well as surface adherence assays. Information was recorded on maximum deformation, maximum load, maximum tension and relative stiffness. In tensile testing the bandages brand Kinesio Tex Gold - FP(®) showed higher rates, 3 in 4 properties. During surface adherence tests on the therapeutic elastic tapes the brand Premium Kinesiology 3 NS Tex(®) showed higher rates, 3 in 4 properties analyzed. Tapes from different manufacturers exhibit different characteristics regarding traction and adherence mechanics. Knowledge of these characteristics is fundamental for the optimized use of each tape based on specific therapeutic needs. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This paper presents the concept of using horizontally parallel HTS tapes with AC loss study, and the investigation on possible wireless power transfer (WPT) applications. An example of three parallel HTS tapes was proposed, whose AC loss study was carried out both from experiment using electrical method; and simulation using 2D H-formulation on the FEM platform of COMSOL Multiphysics. The electromagnetic induction around the three parallel tapes was monitored using COMSOL simulation. The electromagnetic induction and AC losses generated by a conventional three turn coil was simulated as well, and then compared to the case of three parallel tapes with the same AC transport current. The analysis demonstrates that HTS parallel tapes could be potentially used into wireless power transfer systems, which could have lower total AC losses than conventional HTS coils.

    For high current superconductors in high magnet fields with currents in the order of 50 kA, single ReBCO coated conductors must be assembled in a cable. The geometry of such a cable is mostly such that combined torsion, axial and transverse loading states are anticipated in the tapes and tape joints. The resulting strain distribution, caused by different thermal contraction and electromagnetic forces, will affect the critical current of the tapes. Tape performance when subjected to torsion, tensile and transverse loading is the key to understanding limitations for the composite cable performance. The individual tape material components can be deformed, not only elastically but also plastically under these loads. A set of experimental setups, as well as a convenient and accurate method of stress-strain state modeling based on the finite element method have been developed. Systematic measurements on single ReBCO tapes are carried out combining axial tension and torsion as well as transverse loading. Then the behavior of a single tape subjected to the various applied loads is simulated in the model. This paper presents the results of experimental tests and detailed FE modeling of the 3D stress-strain state in a single ReBCO tape under different loads, taking into account the temperature dependence and the elastic-plastic properties of the tape materials, starting from the initial tape processing conditions during its manufacture up to magnet operating conditions. Furthermore a comparison of the simulations with experiments is presented with special attention for the critical force, the threshold where the tape performance becomes irreversibly degraded. We verified the influence of tape surface profile non-uniformity and copper stabilizer thickness on the critical force. The FE models appear to describe the tape experiments adequately and can thus be used as a solid basis for optimization of various cabling concepts.

    Video disk technology is one of the central themes of a technology demonstrator workstation being assembled as a man/machine interface for the Space Station Data Management Test Bed at Johnson Space Center. Langley Research Center personnel involved in the conception and implementation of this workstation have assembled a video production facility to allow production of video disk material for this propose. This paper documents the initial familiarization efforts in the field of video production for those personnel and that facility. Although the entire video disk production cycle was not operational for this initial effort, the production of a simulated disk on video tape did acquaint the personnel with the processes involved and with the operation of the hardware. Invaluable experience in storyboarding, script writing, audio and video recording, and audio and video editing was gained in the production process.

  12. Peeling of a tape with large deformations and frictional sliding

    An analytical model of peeling of an elastic tape from a substrate is presented for large deformations and scenarios where sliding occurs in the adhered regions, with this motion resisted by interfacial shear tractions. Two geometries are considered: the first has a detached segment of the tape forming the shape of an inverted letter 'V' between adhered sections (double-sided peeling), and the second has a free end of the tape being pulled (single-sided peeling). The mechanics of peeling is analyzed in terms of the applied force, displacement of the load point and the angle that the peeled tape makes with the substrate. Formulae are provided for the energy released per unit area of peeling that explicitly and separately account for the work done by frictional sliding. Assuming that peeling occurs when the energy released per unit area equals the work of separation for purely normal separation, it is shown that the critical force to propagate peeling can be significantly higher with sliding as compared to pure sticking. Similarly, due to frictional dissipation, the amount of work done by the applied force needed to propagate peeling can be significantly greater than the work of separation. For the single-sided peel test, an effective mixed-mode interface toughness is presented to be used with purely sticking models when sliding is not explicitly modeled: the closed-form result closely mirrors common empirical forms used to predict mixed-mode delamination.

    Ratcliffe, James G.; DeCarvalho, Nelson V.

    2014-01-01

    A modification to a recently developed test specimen designed to investigate migration of a delamination between neighboring ply interfaces in tape laminates is presented. The specimen is a cross-ply laminated beam consisting of 40 plies with a polytetrafluoroethylene insert spanning part way along its length. The insert is located between a lower 0-degree ply (specimen length direction) and a stack of four 90-degree plies (specimen width direction). The modification involved a stacking sequence that promotes stable delamination growth prior to migration, and included a relocation of the insert from the specimen midplane to the interface between plies 14 and 15. Specimens were clamped at both ends onto a rigid baseplate and loaded on their upper surface via a piano hinge assembly, resulting in a predominantly flexural loading condition. Tests were conducted with the load-application point positioned at various locations along a specimen's span. This position affected the sequence of damage events during a test.

    [Purpose] The purpose of this study was to compare the effects of Kinesio taping and spiral taping on menstrual pain and premenstrual syndrome, to investigate the efficacy of the two types of taping as methods for alleviating menstrual pain and premenstrual syndrome. [Subjects and Methods] The subjects of this study were 34 unmarried women. The subjects were randomly divided into a Kinesio taping group, a spiral taping group and a control group. Subjects with a regular menstrual cycle underwent taping a total of six times; twice a week for about three weeks, starting from 14 days before menstruation and continuing until its end. Degrees of menstrual pain and premenstrual syndrome were measured before the application of taping. [Results] The results revealed that Kinesio taping had significant effects on menstrual pain, while spiral taping was effective at alleviating both menstrual pain and premenstrual syndrome. [Conclusion] Both taping methods before menstruation brought significant relief to menstrual pain, which suggests that spiral taping is an effective method of alleviating premenstrual symptoms.

When compared measuring of pre and post pain levels between three groups, there is no significant change in pain level between Kinesio taping and McConnell taping as also compared to sham taping. Conclusion: The study concluded that Kinesio taping, McConnell taping and sham taping shown immediate effect on reducing pain during functional activities such as stair climbing, stair descent and squat lift with greater percentage of pain reduction was found following Kinesiotaping and McConnell taping.

  18. Transfer of adhesive tape between calender rolls

    Johnson, K. L.; Kauzlarich, J. J.

    2004-03-01

    In the calendering process a tape or sheet of deformable material passes through the nip between hard cylindrical rollers. Usually the rolls are driven at the same peripheral speed, but small differences in speed, often referred to as 'creep', can occur if one of the rolls is externally driven and the other is driven by the friction in the contact. In these circumstances it has been observed that a tape that enters the nip adhering to the driven (slower) surface may transfer at exit to the driving (faster) surface but not the other way round. The mechanics of this transfer process is examined theoretically and experimentally in this paper for the case of double sided adhesive tape. It is argued that on emerging from the nip the tape will separate from the surface at which the shear strain in the adhesive is greater and that for transfer to occur the contact load must be sufficient to cause plastic extension of the tape.

    CERN currently manages the largest data archive in the HEP domain; over 180PB of custodial data is archived across 7 enterprise tape libraries containing more than 25,000 tapes and using over 100 tape drives. Archival storage at this scale requires a leading edge monitoring infrastructure that acquires live and lifelong metrics from the hardware in order to assess and proactively identify potential drive and media level issues. In addition, protecting the privacy of sensitive archival data is becoming increasingly important and with it the need for a scalable, compute-efficient and cost-effective solution for data encryption. In this paper, we first describe the implementation of acquiring tape medium and drive related metrics reported by the SCSI interface and its integration with our monitoring system. We then address the incorporation of tape drive real-time encryption with dedicated drive hardware into the CASTOR [1] hierarchical mass storage system.

    The core loss, that is, the power loss, of a soft ferromagnetic material is a function of the flux density, frequency, temperature, excitation type (voltage or current), excitation waveform (sine, square, etc.) and lamination or tape thickness. In previously published papers we have reported on the specific core loss and dynamic B-H loop results for several polycrystalline, nanocrystalline, and amorphous soft magnetic materials. In this previous research we investigated the effect of flux density, frequency, temperature, and excitation waveform for voltage excitation on the specific core loss and dynamic B-H loop. In this paper, we will report on an experimental study to investigate the effect of tape thicknesses of 1, 1/2, 1/4, and 1/8-mil Permalloy type magnetic materials on the specific core loss. The test cores were fabricated by winding the thin tapes on ceramic bobbin cores. The specific core loss tests were conducted at room temperature and over the frequency range of 10 kHz to 750 kHz using sine wave voltage excitation. The results of this experimental investigation will be presented primarily in graphical form to show the effect of tape thickness, frequency, and magnetic flux density on the specific core loss. Also, the experimental results when applied to power transformer design will be briefly discussed.

    Results from a demonstration project aimed at cutting red tape in federal grants for basic research at universities are "very encouraging" so far, according to Don I. Phillips, executive director of the Government-University-Industry Research Roundtable. The roundtable is coordinating the experimental effort, with the participation of five major federal agencies as well as the Florida state university system and the University of Miami (a private institution in Coral Gables, Fla.).Under the project, special conditions apply to grants from the participating agencies to individual researchers at the participating universities: Investigators do not have to ask the agency's permission for changes in budget allocations, purchases of permanent equipment, or foreign travel. Grant money can be spent up to a year after the grant ends without a special request. Under this plan, researchers, with agency approval, can also ask to have their entire research program covered as a single administrative entity, rather than as several individual projects.

    Interactive video and television viewers should have the power to control their viewing position. To make this a reality, we introduce the concept of Immersive Video, which employs computer vision and computer graphics technologies to provide remote users a sense of complete immersion when viewing an event. Immersive Video uses multiple videos of an event, captured from different perspectives, to generate a full 3D digital video of that event. That is accomplished by assimilating important information from each video stream into a comprehensive, dynamic, 3D model of the environment. Using this 3D digital video, interactive viewers can then move around the remote environment and observe the events taking place from any desired perspective. Our Immersive Video System currently provides interactive viewing and `walkthrus' of staged karate demonstrations, basketball games, dance performances, and typical campus scenes. In its full realization, Immersive Video will be a paradigm shift in visual communication which will revolutionize television and video media, and become an integral part of future telepresence and virtual reality systems.

    Video carving has become an essential tool in digital forensics. Video carving enables recovery of deleted video files from hard disks. Processing data to extract videos is a computationally intensive task. In this paper we present two methods to accelerate video carving: a method to accelerate fragment extraction, and a method to accelerate combining of these fragments into video segments. Simulation results show that complexity of video fragment extraction can be reduced by as much as 75% with minimal impact on the videos recovered.

    Netzelmann, U.

    1990-08-01

    The room-temperature ferromagnetic resonance (FMR) spectra of γ-Fe2O3, CrO2, and barium ferrite particulate magnetic recording tapes have been measured at microwave frequencies of 9.35 and 35 GHz for various orientations of the static and high-frequency magnetic fields with respect to the tape. For CrO2 tapes, the influence of the width of the angular distribution of the particle orientations on the FMR spectra has been studied from the nearly isotropic case up to the highly oriented case. Hysteretic behavior for a CrO2 tape as well as the effect of tape calendering for a γ-Fe2O3 tape has been observed by FMR. Experimental results are found to be in reasonable agreement with results of theoretical calculations based on a model of an ellipsoidal single-domain particle with both shape and magnetocrystalline anisotropy. Magnetostatic interaction inside the magnetic film has been introduced by expressing the total magnetostatic energy as a combination of a part dependent on particle shape and a part dependent on the shape of the tape. As a result of a comparison of experimental data with calculated data from the model, the magnetocrystalline easy axis of the CrO2 particles is found to be parallel with the particle axis.

    Full text: Superconducting Bi-2223 silver sheathed tapes show a critical current density large enough for power transmission line applications where the magnetic fields involved are small. Unfortunately, the performance of these tapes at 77 K in large fields is quite poor and a better understanding of magnetization data might help to elucidate the reasons for the limitation of the tape`s current carrying capacity. We have investigated by means of magnetic moment measurements on monofilamentary Bi-2223 tapes, using a Quantum Design SQUID magnetometer, the correlation between intergranular critical current density J{sub c}{sup J} which is flowing over the entire tape, and the intragranular critical current density J{sub c}{sup G} which is flowing inside grains. The experimental data reveal that J{sub c}{sup G} depends strongly on the magnetic history of grains and the value of J{sub c}{sup G}. The anomalous peak seen in magnetization loops of tapes correlates well with the peak seen in the critical current density measured electrically in a decreasing magnetic field. The position of the anomalous peak does not shift further to higher fields when the applied field exceeds the field of full grain penetration. By separating the silver cladding from the superconductor we found that, opposite to common believe, the current does not flow mainly near the superconductor-silver interface but is more homogeneously distributed throughout the filament

Methods: This study was a two-period, two-treatment crossover trial using simulated pediatric patients in the prehospital setting. Each participant was presented with two emergent scenarios; participants were randomized to which case they encountered first, and to which case used the National Park Service (NPS emergency medical services (EMS length-based pediatric emergency resuscitation tape. In the control (without tape case, providers used standard methods to determine medication dosing (e.g. asking parents to estimate the patient’s weight; in the intervention (with tape case, they used the NPS EMS length-based pediatric emergency resuscitation tape. Each scenario required dosing two medications (Case 1 [febrile seizure] required midazolam and acetaminophen; Case 2 [anaphylactic reaction] required epinephrine and diphenhydramine. Twenty NPS EMS providers, trained at the Parkmedic/Advanced Emergency Medical Technician level, served as study participants. Results: The only medication errors that occurred were in the control (no tape group (without tape: 5 vs. with tape: 0, p=0.024. Time to determination of medication dose was significantly shorter in the intervention (with tape group than the control (without tape group, for three of the four medications used. In case 1, time to both midazolam and acetaminophen was significantly faster in the intervention (with tape group (midazolam: 8.3 vs. 28.9 seconds, p=0.005; acetaminophen: 28.6 seconds vs. 50.6 seconds, p=0.036.

    Kinesio-Taping(®) (K-Tape) is used in sports traumatology with the aim of reducing pain and improving blood and lymph circulation. The main objective of the present study was to assess the efficacy of K-Tape on early postoperative pain after anterior cruciate ligament (ACL) reconstruction. The study hypothesis was that K-Tape significantly decreases pain. A prospective non-randomized comparative study was conducted in 2013-2014 and included all patients who underwent primary ACL reconstruction by hamstring graft. Analgesia was standardized. Two groups, "K-Tape" and "controls", were formed according to the days on which the study physiotherapist was present. The K-Tape compression/decompression assembly was applied immediately postoperatively and maintained for 3days. Patients filled out online questionnaires. The main assessment criterion was mean postoperative pain (D0-D3) on a 0-to-10 scale. Secondary criteria were analgesia intake on the three WHO levels, awakening during the night of D0 due to pain, signs of postoperative discomfort, and patient satisfaction. Sixty patients (30 per group) were included, 57 of whom could be assessed: 28 K-Tape, 29 controls; 44 male, 13 female; mean age, 30.9±8.9 years. At inclusion, the two groups were comparable. There was no significant difference in mean (D0-D3) knee pain intensity: 3.8±2.2 for K-Tape, and 3.9±2 for controls (P=0.93). Analysis of variance (ANOVA) found no significant intergroup difference in evolution of pain (P=0.34). There were no other significant differences on the other assessment criteria. K-Tape showed no efficacy on early postoperative pain following ACL reconstruction. III; prospective non-randomized comparative study. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Obwohl mit dem TVT-O, TVT-Secur, TVT-Exact und TVT-Abbrevo in den vergangenen Jahren neue Produkte mit dem gleichen Band entwickelt wurden, ist das klassische, retropubische TVT weiterhin als Goldstandard für die operative Behandlung der weiblichen Belastungsinkontinenz anzusehen. Bei der Wahl des geeigneten Medizinproduktes gilt es, das individuelle Nutzen-Risiko-Verhältnis der Patientin unter Berücksichtigung der persönlichen Erfahrung des Operateurs sorgfältig gegeneinander abzuwägen.

    Microtiter plate (MTP) sealing tapes are commonly applied in bioprocess development and high throughput screening in order to maintain sterile conditions and avoid liquid evaporation. However, only a few of the commercially available sealing tapes are adequately characterized to guarantee both minimal evaporation and sufficient oxygen supply for aerobic cultivation. Therefore, 12 commercially available sealing tapes are analyzed concerning their water vapor and oxygen permeability. The water vapor permeability is assessed by gravimetrically quantifying the liquid loss due to evaporation. Thereby, the sealing tapes are revealed significant differences. Highly permeable sealing tapes are resulted in liquid loss of up to 25% of the initial filling volume after 8 h at 37°C and 45% ambient humidity. Additionally, the tremendous impact of evaporative cooling on the liquid temperature is detected discovering deviations of up to 3.8°C from the set temperature. The oxygen permeability is assessed by measuring the oxygen transfer rate (OTR). Three out of the 12 tested sealing tapes are impermeable to oxygen while the remaining sealing tapes are ensured sufficient oxygen supply. As a result, all examined sealing tapes are inadequate with respect to either water or oxygen permeation. Based on these novel experimental results, prospective improvements of MTP sealing tapes are presented using a model approach. Copyright © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2009-01-01

    Adhesive tapes, the adhesive resins of which can be cured (and thereby rigidized) by exposure to ultraviolet and/or visible light, are being developed as repair patch materials. The tapes, including their resin components, consist entirely of solid, low-outgassing, nonhazardous or minimally hazardous materials. They can be used in air or in vacuum and can be cured rapidly, even at temperatures as low as -20 C. Although these tapes were originally intended for use in repairing structures in outer space, they can also be used on Earth for quickly repairing a wide variety of structures. They can be expected to be especially useful in situations in which it is necessary to rigidize tapes after wrapping them around or pressing them onto the parts to be repaired.

A piezoelectric device has both capacitance and resistance properties in which by applying an electric field from a waveform will exert a mechanical stress that can be monitored for a response. . The typical waveform applied is a sinusoidal waveform of a defined voltage for a defined period. The defined voltage is driven from 0 volts to the positive defined volts then back to 0 and driven to negative defined volts then back to 0. . Example. Vmax set to 10V and period set to 10 ms. . Voltage will start at zero, go to 10 volts, return to zero, go to ]10 volts and return to zero during 10 ms. . Applying this electrical field to a DUT, the capacitance response and resistance response can be observed. CNT tape is easier to manufacture and cheaper than micromachining silicon or other ceramic piezoelectric used in gyroscopes and accelerometers CNT tape properties can be modified during manufacture for specific application CNT tape has enhanced mechanical and thermal properties in addition to unique electrical

  15. Does 'Kinesio tape' alter thoracolumbar fascia movement during lumbar flexion? An observational laboratory study.

    Tu, Shihfan Jack; Woledge, Roger C; Morrissey, Dylan

    2016-10-01

    Changes in thoracolumbar fascial thickness, structure and shear strain are associated with lower back pain (LBP). Therapeutic taping techniques such as Kinesio-Taping (KT) are increasingly used to treat LBP, albeit with variable effects and unclear mechanisms. However, evidence for quantifying how treatment effects in vivo fascia properties is inadequate. We therefore aimed to explore taping mechanisms using an in vivo ultrasound measurement. Thoracolumbar ultrasound videos of known orientations and positions were taken from 12 asymptomatic participants (8 males and 4 females, aged 22.9 ± 3.59) while performing velocity-guided lumbar flexion with and without KT applied. An automated algorithm using cross-correlation to track contiguous tissue layers across sequential frames in the sagittal plane, was developed and applied to two movements of each subject in each taping condition. Differences of inter-tissue movements and paracutaneous translation at tissue boundaries were compared. Significant reduction in the mean movement of subcutaneous tissue during lumbar flexion before and after taping was found. There was no difference in other observed tissue layers. Tissue paracutaneous translations at three boundaries were significantly reduced during lumbar flexion when KT was applied (skin-subcutaneous: 0.25 mm, p < 0.01; subcutaneous-perimuscular tissue: 0.5 mm, p = 0.02; and perimuscular-muscle: 0.46, p = 0.05). No overall reduction in lumbar flexion was found (p = 0.10). KT reduced subcutaneous inter-tissue movement and paracutaneous translation in the superficial thoracolumbar fascia during lumbar flexion, and the relationship of such difference to symptomatic change merits exploration. Combining ultrasound data with muscle activation information may be useful to reveal potential mechanisms of therapeutic taping in patients with LBP. Copyright © 2016 Elsevier Ltd.

    The present study aimed to investigate the effects of Kinesio Taping on the trajectory of the forelimb and the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses. 19 horses and ponies of different breeds (body weight: 496±117 kg), gender (8 mares, 10 geldings and 3 stallions) and ages (14.9±6.9 years old) were analysed without Kinesio Tape ("no tape"), with Kinesio Tape (muscle facilitation application on both muscles of both sides, "with tape") and immediately after Kinesio Taping ("post tape") through kinematic motion analysis and surface electromyography on a treadmill at the walk (speed: 1.5±0.1 m/s) and trot (speed: 3.1±0.3 m/s). The results of the surface electromyography (maximum muscle activity at the walk and trot) and the kinematic motion analysis (maximum stride length and maximum height of the forelimbs flight arc at the walk and trot) showed that there were no significant differences between "no tape", "with tape" and "post tape". To sum up, Kinesio Taping on the M. brachiocephalicus and the M. extensor carpi radialis does not affect (in a positive or negative manner) the trajectory of the forelimb or the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses.

  18. Fabrication of Polyimide-Matrix/Carbon and Boron-Fiber Tape

    The term HYCARB denotes a hybrid composite of polyimide matrices reinforced with carbon and boron fibers. HYCARB and an improved process for fabricating dry HYCARB tapes have been invented in a continuing effort to develop lightweight, strong composite materials for aerospace vehicles. Like other composite tapes in this line of development, HYCARB tapes are intended to be used to build up laminated structures having possibly complex shapes by means of automated tow placement (ATP) - a process in which a computer-controlled multiaxis machine lays down prepreg tape or tows. The special significance of the present process for making dry HYCARB for ATP is that it contributes to the reduction of the overall cost of manufacturing boron-reinforced composite-material structures while making it possible to realize increased compression strengths. The present process for making HYCARB tapes incorporates a "wet to dry" process developed previously at Langley Research Center. In the "wet to dry" process, a flattened bundle of carbon fiber tows, pulled along a continuous production line between pairs of rollers, is impregnated with a solution of a poly(amide acid) in N-methyl-2-pyrrolidinone (NMP), then most of the NMP is removed by evaporation in hot air. In the present case, the polyamide acid is, more specifically, that of LaRC. IAX (or equivalent) thermoplastic polyimide, and the fibers are, more specifically, Manganite IM7 (or equivalent) polyacrylonitrile- based carbon filaments that have a diameter of 5.2 m and are supplied in 12,000-filament tows. The present process stands in contrast to a prior process in which HYCARB tape was made by pressing boron fibers into the face of a wet carbon-fiber/ poly(amide acid) prepreg tape . that is, a prepreg tape from which the NMP solvent had not been removed. In the present process, one or more layer(s) of side-by-side boron fibers are pressed between dry prepreg tapes that have been prepared by the aforementioned gwet to dry h

    Kinesio taping (KT) is a method of elastic bandaging that produces a biomechanical effect on the organism. This study aims to evaluate its use in dysphonic patients tratment, as integrated part of speech therapy. Randomized controlled MATERIALS AND METHODS: Fifteen dysphonic patients were given the option to complement the speech therapy treatment with KT (DG1). 15 dysphonic patients suffering from similar conditions (DG2) who underwent traditional speech therapy were the control group. After treatment, both DG1 and DG2 obtained a statistically significant improvement for jitter and noise-to-harmonic ratio (P >0.05) and showed an improvement in Voice Handicap Index (VHI) total (VHIt), VHI functional (VHIf), VHI emotional (VHIe), and VHI physical (VHIp). However, the improvement was statistically significant for VHIt (P =0.0102), VHIe (P =0.0349), and VHIp (P =0.0366) in DG1, and only in VHIt (P =0.0466) in DG2. In DG1, P had a lower value than in DG2 for VHIt, VHIe, and VHIp. In DG2, there were a few patients who after therapy had a VHIt higher than before therapy, whereas this did not occur in DG1. As expected, this study confirms the benefits of speech therapy. Although KT is not a substitute for speech therapy, our preliminary results and patients' favorable response to KT encouraged us to continue with our studies on a larger scale. Further studies are required to better define the role of KT in speech therapy and evaluate its real effect over its placebo effect. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    We present the case of a 46-year-old woman who developed severe pain described as 'tearing' and 'searing' in the left side of the mid-trapezius region near the thoracic 8 vertebra (T8). The patient had undergone surgery for T8 fracture which had resulted from metastasis (secondary breast cancer). A community nurse referred the patient for physiotherapy assessment and treatment for her musculoskeletal pain and related symptoms that had affected her mobility and functional activities. The patient was treated with soft tissue therapy with the addition of kinesiology taping on follow-up visits. Kinesiology tape was applied over her left side trapezius region and left shoulder. The patient reported significant reductions in pain severity and felt greater control and stability over her left shoulder region, which resulted in better function and overall quality of life measures. She did not report any adverse effects. 2016 BMJ Publishing Group Ltd.

    For some applications, short unit lengths of HTS wires should be spliced if longer lengths are necessary and short unit lengths of HTS wires should be utilize by applying the splice technology to reduce the total wire cost in the application. The splice technology has been developed for DI-BSCCO Type HT-CA tapes by Sumitomo Electric and spliced tapes were tested in Russian Cable Institute. The test program included: measurements of splice's resistance, critical current anisotropy, thermo cycling tolerance, mechanical properties, overload tests and magnetization measurements. In the paper the results of tests are presented and discussed. The test results demonstrated that splices can be used for cable production if twisting and bending limitations are taken into account.

    Full Text Available The present study investigated the effect of taping and the semi-rigid ankle brace on ankle joint position sense. Sixteen healthy women (20.8 ± 2.3 years old actively placed the ankle in a target position. The experimental conditions were: 1 wearing no orthosis device, 2 using semi-rigid brace, and 3 wearing ankle taping. Absolute error (AE and variable error (VE were calculated to obtain the joint position sense. We found an interaction effect between condition and target angle at 15o of plantar flexion for the variable VE, which showed smaller errors during the use of taping and semi-rigid brace. In conclusion, the use of ankle joint orthoses, whether taping or semi-rigid brace, decrease the variability of the position sense at 15o of plantar flexion, potentially decreasing ankle sprains occurrence.

    High edge definition of a scale grating is the basic prerequisite for high measurement accuracy of optical encoders. This paper presents a novel fabrication method of steel tape gratings using graphene oxide nanoparticles as anti-reflective grating strips. Roll-to-roll nanoimprint lithography is adopted to manufacture the steel tape with hydrophobic and hydrophilic pattern arrays. Self-assembly technology is employed to obtain anti-reflective grating strips by depositing the graphene oxide nanoparticles on hydrophobic regions. A thin SiO2 coating is deposited on the grating to protect the grating strips. Experimental results confirm that the proposed fabrication process enables a higher edge definition in making steel-tape gratings, and the new steel tape gratings offer better performance than conventional gratings.

    2016-05-01

    [Purpose] Many assumptions have been made about taping and several studies have considered tape application methods; however, the true effect of taping on muscle strength remains unclear. Most previous studies compared application techniques using Kinesio tape (KT), but studies that compared muscle strength using non-elastic tape (NT) are limited. Moreover, no studies have applied KT and NT in the same way to assess grip strength in normal subjects. The purpose of this study was to evaluate the immediate effect of application of two tapes with different elastic properties on maximal grip strength in healthy adults. [Subjects and Methods] Twenty healthy adults were divided into two groups (KT and NT). Maximal grip strength was measured with a dynamometer. Forearm extensor muscles of the dominant hand were then taped and subjects were immediately asked to perform hand grip movement with maximum strength in the same standardized manner. [Results] In the KT group, maximal grip strength was significantly increased compared to the initial value; however, in the NT group, there was no significant difference in maximal grip strength. [Conclusion] This study suggests that only Kinesio tape can increase maximal grip strength immediately after application on the extensor region of the forearm.

Analysis--Proportions of correct scores were compared using chi-square, and relative risk was calculated to measure the strength of the association. 75 participants were included in Phase I. In Phase II, 46 participants participated in a parallel cohort design: 20 used GCS reference cards and 26 did not use the cards. Before observing the instructional video, only 14.7% score all of the scenarios correctly, where as after viewing the video, 64.0% scored the scenarios results were observed after viewing the video for those who used the GCS cards (p = 0.001; RR = 2.0; 95% CI = 1.29 to 3.10) than for those not using the cards (p < 0.0001; RR = 10.0; 95% CI = 2.60 to 38.50). Post-video viewing scores were better than those observed before the video presentation. Ongoing evaluations include analysis of long-term skill retention and scoring accuracy in the clinical environment.

    Background Patellar taping is widely used clinically to treat patients with patellofemoral pain syndrome (PFPS). Although patellar taping has been demonstrated to reduce patellofemoral pain in patients with PFPS, the kinematic source for this pain reduction has not been identified. Objective The purpose of this study was to quantify the changes in the 6-degrees-of-freedom patellofemoral kinematics due to taping in patients with PFPS. Design A within-subject design and a sample of convenience were used. Participants Fourteen volunteers (19 knees) who were diagnosed with patellofemoral pain that was present for a year or longer were included. Each knee had to meet at least 1 of the following inclusion criteria: Q-angle of ≥15 degrees, a positive apprehension test, patellar lateral hypermobility (≥10 mm), or a positive “J sign.” Methods Each knee underwent 2 randomly ordered testing conditions (untaped and taped). A full fast-phase contrast (PC) magnetic resonance image set was acquired for each condition while the participants volitionally extended and flexed their knee. Three-dimensional displacements and rotations were calculated through integration of the fast-PC velocity data. Statistical comparisons between baseline patellofemoral kinematics and the change in kinematics due to taping were performed using a 2-tailed paired Student t test. Correlations between baseline patellofemoral kinematics and the change in kinematics due to taping also were quantified. Results Patellar taping resulted in a significant patellofemoral inferior shift. The strongest correlation existed between the change in lateral-medial displacement with taping and baseline (r=−.60). Conclusions The inferior shift in patellar displacement with taping partially explains the previously documented decrease in pain due to increases in contact area. The lack of alteration in 5 of the 6 kinematic variables with taping may have been due to the fact that post-taping kinematic alterations are

    [Purpose] The purpose of the present study was to examine the effects of kinesiology taping therapy on degenerative knee arthritis patients' pain, function, and joint range of motion. [Subjects] To conduct the experiment in the present study, 30 patients with degenerative knee arthritis were divided into a control group (the conservative treatment group) of 15 patients, who received conservative physical therapy, and an experimental group (the kinesiology taping group) of 15 patients, who received kinesiology taping therapy. [Methods] All patients received treatment three times per week for four weeks. The kinesiology taping group had elastic tapes applied to the hamstring muscles, anterior tibialis, quadriceps femoris, and gastrocnemius. The range of motion was measured using joint goniometers, pain was measured using visual analog scales, and functional evaluation was conducted using the Korean Western Ontario and McMaster Universities Osteoarthritis Index. [Results] In intragroup comparisons of the kinesiology taping group and the conservative treatment group, the visual analog scale and Korean Western Ontario and McMaster Universities Osteoarthritis Index scores significantly decreased, and the range of motion increased more than significantly. In intergroup comparisons, the kinesiology taping group showed significantly lower visual analog scale and Korean Western Ontario and McMaster Universities Osteoarthritis Index scores and significantly larger ranges of motion than the conservative treatment group. [Conclusion] Kinesiology taping therapy is considered to be an effective nonsurgical intervention method for pain relief, daily living activities, and range of motion of degenerative knee arthritis patients.

    2010-02-01

    It has been increasingly recognized that some people develop problem video game use, defined here as excessive use of video games resulting in various negative psychosocial and/or physical consequences. The main objectives of the present study were to identify individuals with problem video game use and compare them with those without problem video game use on several variables. An international, anonymous online survey was conducted, using a questionnaire with provisional criteria for problem video game use, which the authors have developed. These criteria reflect the crucial features of problem video game use: preoccupation with and loss of control over playing video games and multiple adverse consequences of this activity. A total of 1945 survey participants completed the survey. Respondents who were identified as problem video game users (n = 156, 8.0%) differed significantly from others (n = 1789) on variables that provided independent, preliminary validation of the provisional criteria for problem video game use. They played longer than planned and with greater frequency, and more often played even though they did not want to and despite believing that they should not do it. Problem video game users were more likely to play certain online role-playing games, found it easier to meet people online, had fewer friends in real life, and more often reported excessive caffeine consumption. People with problem video game use can be identified by means of a questionnaire and on the basis of the present provisional criteria, which require further validation. These findings have implications for recognition of problem video game users among individuals, especially adolescents, who present to mental health services. Mental health professionals need to acknowledge the public health significance of the multiple negative consequences of problem video game use.

    Although most cases of malignant mesothelioma of the pleura are caused by one or more readily recognized sources of exposure to asbestos, cases of the disease with more occult exposure occur, especially since asbestos has been used in over 3,000 products. Dental lining tape contained asbestos from the 1930s until at least the 1970s and was used in the lost wax method of casting crowns, bridges, and other metal dental prosthetic devices. We report six cases of pathology-verified malignant mesothelioma, mostly among dentists, following exposure to airborne dust from asbestos dental tape, which resulted in asbestos tort litigation. According to evidence available at present, chrysotile asbestos was the type of asbestos used in dental tape in the past in the United States, and the described cases followed relatively brief and intermittent exposure to this type of asbestos. These cases underscore the need for comprehensive exposure histories to determine exposure scenarios. Am. J. Ind. Med. 60:437-442, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Due to the fundamental role of gripping in most upper limb activities, grip strength promotion is a chief goal in the treatment of patients with upper limb musculoskeletal disorders. Kinesio taping is a novel and effective therapeutic technique believed to facilitate muscle contraction through stimulating mechanoreceptors and increasing the sensory feedback around the taped region. The present study aimed to identify the best region (flexor, extensor and flexor/extensor regions) and time (immediate, 0.5, 1, 1.5, and 2 hours) of forearm Kinesio taping to obtain the maximum improvement in grip strength. In this longitudinal study, 40 healthy men and women (the mean age of 22.3 ± 2.19 years) were selected among students of Shahid Beheshti University of Medical Sciences, Tehran, Iran by simple, nonrandom sampling method. A dynamometer was used to measure grip strength immediately and every 30 minutes during the two hours after I-shaped application of tape (with 50% stretch) to the flexor, extensor, and flexor/extensor forearm muscles. Grip strength was significantly increased in various muscle groups for males (P = 0.002) and females (P = 0.000) of the forearm and at different intervals for males (P = 0.000) and females (P = 0.000). Moreover, in both men and women, tape application to the extensor region provided greater grip strength compared to taping of the flexor and flexor/extensor regions (P = 0.000 for both). Furthermore, the maximum increase in grip strength were 0.5 (10.8% increase, P = 0.001) and 1.5 h (23.9% increase, P = 0.000) after taping in males and females, respectively. Taping the extensor region of forearm is recommended to achieve higher grip strength. Although grip strength increased at a slower pace in females than males, the final values were higher in women.

    The elastic therapeutic taping has been considered a promising resource for disabled children. To systematically review the evidence of the effects of elastic therapeutic taping on motor function in children with motor impairments. Three independent evaluators conducted searches in electronic databases (MEDLINE/PubMed, Scopus, LILACS, BIREME/BVS, Science Direct, SciELO, and PEDro). Clinical studies design, published until 2016, involving elastic therapeutic taping and children aged 0-12 years with motor impairments were included. The variables considered were the methodological aspects (study design, participants, outcome measurements, and experimental conditions); results presented in the studies, and also the methodological quality of studies. Final selection was composed by 12 manuscripts (five randomized controlled trials), published in the last 10 years. Among them, cerebral palsy (CP) was the most recurrent disorder (n = 7), followed by congenital muscular torticollis (n = 2) and brachial plexus palsy (n = 2). Positive results were associated with taping application: improvement in the upper limb function, gross motor skills, postural control, muscular balance, and performance in the dynamics functional and daily activities. Lower quality of the studies, clinical and population heterogeneity existed across studies. The elastic therapeutic taping has been shown to be a promising adjunct resource to the conventional rehabilitation in children with motor impairments. However, high methodological studies about its efficacy in this population are already scarce. Implications for Rehabilitation Elastic therapeutic taping has been shown to be a promising adjunct resource to the conventional rehabilitation in disabled children. Clinical trials have indicated improvement in the postural control and functional activities with both, upper and lower limbs, and increase in the functional independency resulting from the taping use.

    This paper presents a method to increase fixing stiffness of mobile machine by using filament tapes. Mobile machine moves on a large workpiece for cutting, drilling, welding, and cleaning, etc., so for those works. The vacuum pads are generally used for attaching or detaching objects frequently. Of course, if the object is a metal body, the magnetic force can be used. The vacuum pads have an advantage that it can be used regardless of the magnetic property of the object, but it has a disadvantage that the fixing stiffness is not strong because the material is rubber. That’s why it is difficult to maintain the accurate position of the mobile machine as it could be shaken when being moved or fixed. Thus, this study proposed a method to increase the horizontal fixing stiffness of the mobile machine by using filament tapes to the side of the vacuum pads which compensate the shortcoming of the vacuum pads. Filament tapes are made by inserting special material filaments which have high rigidity into an existing tape to increase tensile strength. In the configuration of the proposed method, the vacuum pad forms the vertical fixing stiffness by suction force, and the filament tape forms the horizontal fixing stiffness by adhesive force. In order to verify the effectiveness of the proposed method, the experimental equipment to measure the fixing stiffness was fabricated, and the comparison experiment was carried out. First, the horizontal fixing stiffness of the vacuum pads and the filament tape was measured respectively as a baseline data, and then the same measurement of the combination of them was performed for the comparison. In addition, another experiment for comparison between Gecko films and filament tape was performed. The results showed that the horizontal fixing stiffness was significantly increased when the filament tape was used together with the vacuum pads, and the Gecko film was not as much effective as the filament tape in terms of the strength of the

    Full Text Available We present a user-based method that detects regions of interest within a video in order to provide video skims and video summaries. Previous research in video retrieval has focused on content-based techniques, such as pattern recognition algorithms that attempt to understand the low-level features of a video. We are proposing a pulse modeling method, which makes sense of a web video by analyzing users' Replay interactions with the video player. In particular, we have modeled the user information seeking behavior as a time series and the semantic regions as a discrete pulse of fixed width. Then, we have calculated the correlation coefficient between the dynamically detected pulses at the local maximums of the user activity signal and the pulse of reference. We have found that users' Replay activity significantly matches the important segments in information-rich and visually complex videos, such as lecture, how-to, and documentary. The proposed signal processing of user activity is complementary to previous work in content-based video retrieval and provides an additional user-based dimension for modeling the semantics of a social video on the web.

    Wounds closed by adhesive tapes have less inflammatory reaction, a lower rate of wound infection, greater tensile strength and better cosmetic results than sutured or stapled wounds. Special backing tapes, such as Steri-Strip, have been reported to have satisfactory results in closing laparotomy wounds. However, they are more expensive than paper tape. Sterile paper tape had adequate adhesive and supporting strength in the closure of abdominal wounds. The wounds closed with paper tape healed well and had satisfactory cosmetic results. Paper tape is a nonexpensive and convenient alternative to close abdominal wounds.

    Skin surface tape-stripping is an extensively used technique to examine the distribution profile, penetration and safety of various active compounds. It is also a widely accepted method to probe skin barrier properties and more specifically, those of the stratum corneum (SC). The amount of SC removed by tape-stripping is generally determined either gravimetrically or by extraction and measurement of SC proteins. A novel infra-red densitometry (IRD) technique has recently been introduced to measure SC protein content. In the present study, IRD was investigated as an alternative method to measure the mass of SC removed by tape-stripping. Tape-stripping experiments were conducted on human volunteers. The weight of the stratum corneum removed was assessed by the gravimetric approach and by IRD. Transepidermal water loss (TEWL) was also measured before and after each tape-strip. A linear correlation coefficient was obtained for the data from the gravimetric and IRD measurements (r(2)=0.65; n=240). IRD is therefore proposed as a rapid, non-destructive alternative to the gravimetric approach to estimate the amount of SC removed by tape-stripping in vivo. Copyright © 2012 Elsevier B.V.

    To review the effects achieved by the kinesio tape in patients with stroke in scientific studies published on date and to discuss these findings may be of interest to neurology. An exhaustive search in the main scientific databases using keywords such as kinesio tape, kinesiotaping, musculoskeletal tape, taping medical concept was carried out. Citations of selected articles and scientific papers published on the website of the Spanish Association of Neuromuscular Bandage were analyzed. Experimental, quasi-experimental, clinical trials and case studies published were used, without limit date, with therapeutical treatment purpose provide important results. Eight articles have met the inclusion criteria. There are eight studies that examine the effect on kinesio tape on lower limb, gait and balance in this kind of therapy, even upper limb and swallowing problems that these patients could present. The kinesio tape in neurological patients can be a complementary technique that empirically provides benefits. However, better methodological quality studies demonstrating the effects attributed to him are still needed.

    With ever-increasing volumes of video data, automatic extraction of salient object regions became even more significant for visual analytic solutions. This surge has also opened up opportunities for taking advantage of collective cues encapsulated in multiple videos in a cooperative manner. However, it also brings up major challenges, such as handling of drastic appearance, motion pattern, and pose variations, of foreground objects as well as indiscriminate backgrounds. Here, we present a cosegmentation framework to discover and segment out common object regions across multiple frames and multiple videos in a joint fashion. We incorporate three types of cues, i.e., intraframe saliency, interframe consistency, and across-video similarity into an energy optimization framework that does not make restrictive assumptions on foreground appearance and motion model, and does not require objects to be visible in all frames. We also introduce a spatio-temporal scale-invariant feature transform (SIFT) flow descriptor to integrate across-video correspondence from the conventional SIFT-flow into interframe motion flow from optical flow. This novel spatio-temporal SIFT flow generates reliable estimations of common foregrounds over the entire video data set. Experimental results show that our method outperforms the state-of-the-art on a new extensive data set (ViCoSeg).

    During the coming years, digital data storage technologies will continue an aggressive growth to satisfy the user's need for higher storage capacities, higher data transfer rates and long-term archival media properties. Digital optical tape is a promising technology to satisfy these user's needs. As any emerging data storage technology, the industry faces many technological and standardization challenges. The technological challenges are great, but feasible to overcome. Although it is too early to consider formal industry standards, the optical tape industry has decided to work together by initiating prestandardization efforts that may lead in the future to formal voluntary industry standards. This paper will discuss current industry optical tape drive developments and the types of standards that will be required for the technology. The status of current industry prestandardization efforts will also be discussed.

    Hybrid porphyrin tapes 3 and 4, consisting of a mixture of 3,5-di-tert-butylphenyl-substituted donor-type Zn(II)-porphyrins and pentafluorophenyl-substituted acceptor-type Zn(II)-porphyrins, were prepared by a synthetic route involving cross-condensation reaction of a Ni(II)-porphyrinyldipyrromethane and pentafluorophenyldipyrromethane with pentafluorobenzaldehyde followed by appropriate demetalation, remetalation, and oxidative ring-closure reaction. The Ni(II)-substituted porphyrin tapes 5 (Ni-Zn-Ni) and 6 (Ni-H(2)-Ni) were also prepared through similar routes. The hybrid porphyrin tapes 3 and 4 are more soluble and more stable than normal porphyrin tapes 1 and 2 consisting of only donor-type Zn(II)-porphyrins. The solid-state and crystal packing structures of 3, 4, and 5 were elucidated by single-crystal X-ray diffraction analysis. Singly meso-meso-linked hybrid porphyrin arrays 12 and 14 exhibit redox potentials that roughly correspond to each constituent porphyrin segments, while the redox potentials of the hybrid porphyrin tapes 3 and 4 are positively shifted as a whole. The two-photon absorption (TPA) values of 1-6 were measured by using a wavelength-scanning open aperture Z-scan method and found to be 1900, 21,000, 2200, 27,000, 24,000, and 26,000 GM, respectively. These results illustrate an important effect of elongation of π-electron conjugation for the enhancement of TPA values. The hybrid porphyrin tapes show slightly larger TPA values than the parent ones. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    temperature was investigated through the use of an environmental chamber. Extensive use was made of surface specific analytical techniques such as XPS, AFM, AES and SEM to study the physical and chemical changes that occur at the head/tape interface. Results showed that cycling improved the signal performance of all the tapes tested. The data cartridge drive belt had an effect on the chemical properties of the tape surface on which it was in contact. Also binder degradation occurred for each tape and appeared to be greater at higher humidity. Lubricant was generally seen to migrate to the tape surface with cycling. Any surface changes likely to affect signal output occurred at the head surface rather than the tape. Many of the recent improvements in the capacity of data cartridge systems have been achieved through the use of narrower tracks, higher linear densities and continuous servo tracking with multi-channel heads. These changes have produced new tribological problems at the head/tape interface. It is cr...

    [Purpose] The aim of this study was to evaluate the overlap effect of the PNF following the application of Kinesio taping and the McConnell taping, and also the impact of the taping application method on the balance and walking speed of the patients with stroke. [Subjects and Methods] Thirty-six patients who were diagnosed with hemiplegia due to stroke were selected as subjects of this study. They were randomly and evenly divided into experiment group 1 (Kinesio taping group), experiment group 2 (McConnell taping group), and the control group; each group had 12 patients. [Results] The Berg balance scale (BBS) was used to evaluate balance, and the ability in this study. A 10 m walking test (10MWT) was performed to measure the walking speed. Experiment group 1 showed a statistically significant improvement in balance and walking speed compared to experiment group 2, and the control group in week 4 and week 8. [Conclusion] Application of Kinesio taping had a more beneficial effect on the balance and walking speed than joint-fixation taping of the patients with stroke.

  11. Placement suitability criteria of composite tape for mould surface in automated tape placement

    2015-10-01

    Full Text Available Automated tape placement is an important automated process used for fabrication of large composite structures in aeronautical industry. The carbon fiber composite parts realized with this process tend to replace the aluminum parts produced by high-speed machining. It is difficult to determine the appropriate width of the composite tape in automated tape placement. Wrinkling will appear in the tape if it does not suit for the mould surface. Thus, this paper deals with establishing placement suitability criteria of the composite tape for the mould surface. With the assumptions for ideal mapping and by applying some principles and theorems of differential geometry, the centerline trajectory of the composite tape is identified to follow the geodesic. The placement suitability of the composite tape is examined on three different types of non-developable mould surfaces and four criteria are derived. The developed criteria have been used to test the deposition process over several mould surfaces and the appropriate width for each mould surface is obtained by referring to these criteria.

    [Purpose] Elastic therapeutic tape has been widely used for rehabilitation and treatment of sports injuries. Tapes with different elastic properties serve different treatment purposes with inappropriate tension reducing tape effectiveness. Many tapes are available in the market, but studies on tape properties are limited. The aim of this study was to examine the material properties of elastic therapeutic tape. [Subjects and Methods] Brands of elastic therapeutic tape included KinesioTex®, ATex, Mueller, 3M, and ThaiTape. The Material Testing System Insight® 1 Electromechanical Testing Systems was used to apply a tensile force on elastic therapeutic tape. Ten specimens of each brand were tested. Stress, load, and Young’s modulus at 25%, 50%, 75%, 100%, and maximum point were collected. One-way analysis of variance with post hoc testing was used to analyze tape parameters. [Results] Maximum elongation and Young’s modulus at all percentages were significantly different between brands. There were no differences in maximum load and maximum stress. [Conclusion] Mechanical properties are different for commercial elastic therapeutic tapes. Physiotherapists and other clinicians should be aware of mechanical tape properties to correctly apply kinesio tape. PMID:27190472

    Kinesio taping consists of the attachment of a thin elastic tape over specific muscles, the thickness of which is similar to that of the epidermis. The aim of the present study was to compare the effect of Kinesio taping and placebo taping on muscle torque, muscle activity and jumping performance soccer players. Thirty athletes were randomly allocated to two groups (Group A: Kinesio taping and Group B: placebo taping). The participants were instructed to perform the Hop test's and were submitted to an isokinetic evaluation of the knee extensors as well as an electromyographic evaluation of the retus femoris muscle of the dominant lower limb. Next, Kinesio taping was performed for the activation of the rectus femoris muscle in Group A and placebo taping was performed in Group B. The participants were reevaluated 30 minutes after taping and 24 hours after the first evaluation using the same tests. Intra-group and inter-group comparisons were made considering the three evaluation times. No statistically significant differences were found between groups at any evaluation time regarding the Hop test's, root mean square of the electromyographic signal or peak torque of the knee extensors of the dominant lower limb (p>0.05). Kinesio taping for the activation of the rectus femoris muscle has no effect on peak muscle torque, muscle activity or jumping performance among soccer players.

    Full Text Available An important task in content based video indexing is to extract text information from videos. The challenges involved in text extraction and recognition are variation of illumination on each video frame with text, the text present on the complex background and different font size of the text. Using various image processing algorithms like morphological operations, blob detection and histogram of oriented gradients the character recognition of video subtitles is implemented. Segmentation, feature extraction and classification are the major steps of character recognition. Several experimental results are shown to demonstrate the performance of the proposed algorithm

    Full Text Available Ankle Instability is characterized by recurrent giving way and often develops after repeated lateral ankle sprains. Kinesiotape is more elastic than traditional athletic tape and is becoming increasingly popular. It is reported to decrease pain, improve muscle function, circulation and proprioception, however, research examining the effects of Kinesiotape in ankle instability is limited. The objective of this study was to determine if applying Kinesiotape to unstable ankle may improve performance in the Star Excursion Balance Test (SEBT, which has been shown to be a sensitive and reliable measure for quantifying dynamic balance. Thirty subjects with first degree ankle sprain were participated in this study. SEBT was used to test the subject dynamic balance under three conditions; without taping, with white athletic tape and with kinesiotape. One way repeated measure ANOVA using Greenhouse-Geisser corrections were conducted to evaluate differences in SEBT for the three conditions. Pairwise comparison of the outcome measures in the three occasions (without taping, with athletic taping, and with kinesio taping revealed statistically significant differences of all outcomes between occasion 1 (without taping and occasion 2 (with athletic taping favoring the athletic taping (p < 0.05. Also, a statistically significant difference between occasion 1 (without taping and occasion 3 (with kinesio taping were found (p < 0.05 favoring kinesio taping. Moreover, pairwise comparison of the ankle stability outcomes using athletic taping versus kinesio taping indicated a statistically significant difference (p < 0.05 in favor of kinesio taping measures. Conclusion: kinesiotape has superior effect than athletic tape in patients with first degree ankle sprain and can be used safely for improving ankle joint stability.

    To compare effects of kinesio taping with sham taping at the end of 3 consecutive taping periods in knee osteoarthritis. 41 patients diagnosed with knee osteoarthritis according to American College of Rheumatology were randomized to receive either KT or sham taping. Baseline evaluations included a visual analog scale (VAS) for activity and nocturnal pain, Lequesne index for functional assessment and Nottingham Health Profile (NHP) for the quality of life. Taping was applied every four days, three times, and all of the assessments were repeated at the end of the treatment period. In both groups VAS for activity pain, VAS for nocturnal pain, Lequesne index score, NHP score decreased significantly. NHP energy scores were different significantly between the groups in favor of sham taping at the end of the 12-day period. Our findings indicate inconclusive evidence of a beneficial effect of kinesio taping over sham taping in knee osteoarthritis. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Abstract Background: Hallux valgus, an increased angle of lateral deviation in the big toe, can cause pain and difficulties in balancing and walking. This study aimed to investigate the effects of balance taping using elastic therapeutic tape on moderate hallux valgus. Methods: When she walked with shoes, she complained of pain over the medial eminence of the hallux metatarsophalangeal (MTP) joint. Balance taping using kinesiology tape was applied for 3 months (average, 16hours/d) to both big toes of a 26-year-old woman with moderate hallux valgus. Results: On the right side, the hallux valgus angle (HVA) decreased from 21° to 14° and the intermetatarsal angle (IMA) decreased from 15° to 14.5°. On the left side, the HVA decreased from 22° to 11° and the IMA decreased from 15° to 12°. Furthermore, the patient was able to walk long distances in shoes without pain in the medial eminence of the hallux metatarsophalangeal joint. Conclusion: This study suggested that repeated balance taping with kinesiology tape could be used as a complementary treatment method for moderate hallux valgus. PMID:27861365

    Full Text Available Digital games make up a significant but little known chapter in the history of the moving image in Australia and New Zealand.  Beginning in the early 1980s, the Australasian software industry developed a remarkable record of content creation. The ``Play It Again'' project is conducting research into the largely unknown histories of 1980s game development in Australia and New Zealand, ensuring that local titles make it into national collections and are documented and preserved, enabling the public to once again play these games. Microcomputers from the 1980s made extensive use of compact audio cassettes to distribute software as an inexpensive alternative to the floppy disk technology available at the time. Media from this era are at risk of degradation and are rapidly approaching the end of their lifespan. As hardware platforms and peripheral devices become obsolete, access to the data for future scholars and other interested parties becomes more difficult. In this article, we present a case study, wherein we investigate the issues involved in making digital copies with a view to the long term preservation of these software artefacts. A video game title stored on standard compact cassette for Commodore's popular VIC-20 machine, ``Dinky Kong'' by Mark Sibley was recorded using both inexpensive amateur and professional playback equipment. The audio files obtained were processed using freely available software, alongside a customised decoder written in MATLAB and Perl. The resulting image files were found to be playable using an emulator. More importantly, the integrity of the data itself was verified, by making use of error detection features inbuilt to the Commodore tape format, which is described in detail. Issues influencing the quality of the recovered image files such as the bit rate of the digital recording are discussed. The phenomenon of audio dropout on magnetic tape is shown be of some concern, however there exist signal processing

    Full Text Available Abstract Background Shoulder problems are a common complaint of the musculoskeletal system. Physical therapists treat these patients with different modalities such as exercise, massage, and shoulder taping. Although different techniques have been described, the effectiveness of taping has not yet been established. The aim of this study is to assess the effectiveness and cost-effectiveness of usual physical therapy care in combination with a particular tape technique for subacromial impingement syndrome of the shoulder compared to usual physical therapy care without this tape technique in a primary healthcare setting. Methods and design An economic evaluation alongside a randomized controlled trial will be conducted. A sample of 140 patients between 18 and 65 years of age with a diagnosis of subacromial impingement syndrome (SAIS as assessed by physical therapists will be recruited. Eligible patients will be randomized to either the intervention group (usual care in combination with the particular tape technique or the control group (usual care without this tape technique. In both groups, usual care will consist of individualized physical therapy care. The primary outcomes will be shoulder-specific function (the Simple Shoulder Test and pain severity (11-point numerical rating scale. The economic evaluation will be performed using a societal perspective. All relevant costs will be registered using cost diaries. Utilities (Quality Adjusted Life Years will be measured using the EuroQol. The data will be collected at baseline, and 4, 12, and 26 weeks follow-up.

    2018-02-13

    An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

  18. Numerical models of delamination behavior in 2G HTS tapes under transverse tension and peel

    Science.gov (United States)

    Duan, Yujie; Ta, Wurui; Gao, Yuanwen

    2018-02-01

    In extreme operating environments, delamination in 2G HTS tapes occurs within and/or near the superconductor layer from high transverse tensile stresses caused by fabrication, Lorentz forces and thermal mismatch, etc. Generally, transverse opening and peeling off are the main delamination modes, and are always studied in anvil and peel tests, respectively. Numerical models of these modes for 2G HTS tape are presented wherein the mixed-mode traction-separation law at the interface of the silver and superconductor layers is considered. Plastic deformations of copper, silver, and Hastelloy® in the HTS tape are taken into account. The results obtained from the transverse opening model show that the maximum average tensile stress is smaller than the delamination tensile strength because delamination is asynchronous in the tape. When a crack appears in the tape, only a small stress ( ≤ 1 MPa) is required to expand the crack to other stress free areas through peeling. Using the peeling model, the dependency of the peel strength on peeling angle is investigated under constant fracture toughness. Peel strength decreases with the peeling angle until the minimum value is reached at 150°, and thereafter increases slightly. Other results indicate that peel strength depends strongly on delamination strength, fracture toughness, and thickness of copper layer. The fracture toughness of the delamination interface, which is difficult to obtain by experiment, can be extracted using the present model.

    Kinesio taping is a therapeutic method used by physiotherapists during musculoskeletal and neuromuscular disorders. Efficacy of the kinesio taping implementation on sport performance is inconsistent. The purpose of this study was to determine the effects of kinesio taping on 30 second-repeated jump power, wingate anaerobic power and wingate anaerobic capacity results. Thirty one healthy male athletes volunteered to participate in this study. The subjects were randomly assigned to one of two groups: a kinesio taping group (16 subjects; X age: 21.87±2.02 years) and a without kinesio taping group (15 subjects; X age: 21.66±1.67 years). The Kinesio taping group was taped with a Y-shaped kinesio tape at the quadriceps muscles according to the Kenzo Kase's Kinesio taping manual. A dependent t-test was used to compare the anaerobic power and capacity measurements before and after the kinesio taping application. No significant differences were found for absolute wingate anaerobic power, relative wingate anaerobic power, absolute wingate anaerobic capacity, relative wingate anaerobic capacity and 30 second-repeated jump power outputs after the kinesio taping application (P>0.05).

    2017-03-01

    To explore the effects of kinesiology taping (KT) and athletic taping (AT) on ankle proprioception when tested in functional, full weight-bearing stance. Cross-sectional study. Twenty-four healthy university students participated. Proprioception was measured using the Active Movement Extent Discrimination Apparatus (AMEDA). The three testing conditions: no-taping, KT, AT, and foot tested were randomly assigned. Perceived comfort, support and proprioceptive performance under two taping conditions were recorded. Proprioceptive discrimination scores with 95% CIs for no-taping, KT and AT were 0.81 (0.79-0.84), 0.81 (0.79-0.83), and 0.79 (0.77-0.81). Repeated measures ANOVA showed neither any significant difference associated with taping compared with no-taping (p=0.30), nor any difference between KT and AT (p=0.19). The group was then divided, according to their no-taping scores, into two sub-groups: with scores below the no-taping mean (n=13), and above the mean (n=11). ANOVA revealed a significant interaction (p=0.008) indicating that above-average no-taping performers proprioception scores were worse when taped, whereas below-average performers improved. For both KT and AT, only ratings of perceived comfort when taped were significantly associated with actual proprioceptive performance (both r>0.44, p≤0.03). Other perception ratings (support and performance) were significantly inter-correlated (both r>0.42, p0.31). Taping of the foot and ankle may amplify sensory input in a way that enhances proprioception of poor performers but produces an input overload that impairs proprioception in those who originally performed well when no-taping. Screening of ankle proprioception may identify those who would benefit most from taping. Copyright © 2016 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

    Comparisons of polyvinyl chloride electrical tape typically rely upon evaluating class characteristics such as physical dimensions, surface texture, and chemical composition. Given the various techniques that are available for this purpose, a comprehensive study has been undertaken to establish an optimal analytical scheme for electrical tape comparisons. Of equal importance is the development of a quantitative means for sample discrimination. In this study, 67 rolls of black electrical tape representing 34 different nominal brands were analyzed via scanning electron microscopy and energy dispersive spectroscopy. Differences in surface roughness, calendering marks, and filler particle size were readily apparent, including between some rolls of the same nominal brand. The relative amounts of magnesium, aluminum, silicon, sulfur, lead, chlorine, antimony, calcium, titanium, and zinc varied greatly between brands and, in some cases, could be linked to the year of manufacture. For the first time, quantitative differentiation of electrical tapes was achieved through multivariate statistical techniques, with 36 classes identified within the sample population. A single-blind study was also completed where questioned tape samples were correctly associated with known exemplars. Finally, two case studies are presented where tape recovered from an improvised explosive device is compared with tape recovered from a suspect.

    There is unequal access to health care in Australia, particularly for the one-third of the population living in remote and rural areas. Video consultations delivered via the Internet present an opportunity to provide medical services to those who are underserviced, but this is not currently routine practice in Australia. There are advantages and shortcomings to using video consultations for diagnosis, and general practitioners (GPs) have varying opinions regarding their efficacy. The aim of this Internet-based study was to explore the attitudes of Australian GPs toward video consultation by using a range of patient scenarios presenting different clinical problems. Overall, 102 GPs were invited to view 6 video vignettes featuring patients presenting with acute and chronic illnesses. For each vignette, they were asked to offer a differential diagnosis and to complete a survey based on the theory of planned behavior documenting their views on the value of a video consultation. A total of 47 GPs participated in the study. The participants were younger than Australian GPs based on national data, and more likely to be working in a larger practice. Most participants (72%-100%) agreed on the differential diagnosis in all video scenarios. Approximately one-third of the study participants were positive about video consultations, one-third were ambivalent, and one-third were against them. In all, 91% opposed conducting a video consultation for the patient with symptoms of an acute myocardial infarction. Inability to examine the patient was most frequently cited as the reason for not conducting a video consultation. Australian GPs who were favorably inclined toward video consultations were more likely to work in larger practices, and were more established GPs, especially in rural areas. The survey results also suggest that the deployment of video technology will need to focus on follow-up consultations. Patients with minor self-limiting illnesses and those with medical

    Cryostats and dewar vessels, in particular those used for liquid helium applications, are usually equipped with multi-layer insulation (MLI). Thereby, multiple foils are wrapped around the respective vessels, tubing and components. As standard, different foils are bonded edge to edge using adhesive tapes either based on aluminized non-metallic films or on aluminum foil. There are a number of standard test procedures for adhesive tapes near ambient temperatures (e.g. AFERA 5012/ISO 29863) allowing a standardized characterization of tapes in terms of holding force and long-term reliability. Unfortunately this does not hold true for adhesive tapes to be used at cryogenic temperatures. In this respect, a test rig comprised of a spring-based traction mechanism has been developed by the authors. Combined with a liquid helium dewar, the fabricated test set-up allows a precise and reproducible application of an adjustable tensile load at 4.2 K and measurements of the respective holding time. In the following, the overall set-up including its significant features is described and first experimental results with aluminum tapes are presented.

    [Purpose] Hemiplegia occurs when posturing with a dominant flexor tone is present in the upper limbs, thus preventing increased abnormal tone. We attempted to improve the side effects of this condition using elbow re-positioning with non-elastic tape; this method is used to modulate abnormal muscle tone in chronic hemiplegic stroke patients. [Subjects and Methods] Fourteen post-stroke patients were included in this study. Non-elastic tape was applied to the elbow joint in a spiral manner. Before and after the tape was applied, the degree of spasticity (hypertonia) was measured in the elbow flexor muscles using the Modified Ashworth Scale (MAS). Global synkinesis (GS) intensity using electromyography (EMG) was measured in the biceps brachii and triceps brachii during voluntary isometric elbow contractions of the contralateral upper limbs. [Results] Application of non-elastic tape at the elbow joint significantly changed the GS intensity, but no significant changes were found when compared with the MAS. [Conclusion] This study demonstrates that non-elastic tape can be used to decrease abnormal elbow flexor tone. The findings may be used to influence the choice of intervention regarding muscle tone and spastic elbow flexion.

    The low-Dye technique serves to limit hindfoot pronation and medial arch collapse. Few studies exist that investigate the effects on medial arch deformation from a biomechanical perspective. Kinematic data was collected using a Motion Analysis System. Foot function of 21 healthy adults was assessed during the stance phase of gait. Subjects were evaluated prior to and immediately following the low-Dye tape application, as well as at 48 h. Foot deformation was assessed during the stance phase of gait using the calcaneus, navicular and 1st metatarsal head markers to calculate the medial longitudinal arch angle (MLA) and the dynamic arch height index (dAHI). Paired t-tests were used to assess low-Dye tape effectiveness. There was a significant 19.3% reduction in MLA immediately after application of the tape. However only 4.01% reduction remained in deformation after 48 h. The MLA deformation findings were consistent with the AHI change, showing a significant change in the arch deformation between Pre and Post0 low-Dye taping. The effects were short-lived. There are measurable changes to medial arch height and amount of arch height deformation during gait following low-Dye taping. Although changes were present immediately after application, results were diminished 48 h after application. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Babić, E.; Kušević, I.; Marinaro, D.; Xue Dou, Shi

    Systematic analysis of the transport critical current densities Jc at 77 K for 235U-oxide (UO22H2O) doped Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3Ox tapes (Bi2223) irradiated with thermal neutrons is presented. Within the explored range of U-oxide concentrations (c £ 2 wt%) and neutron fluences (f £ 6 × 1019 n/m2), the pinning of vortices in irradiated tapes increases approximately linearly with fission track density (proportional to cf), as evidenced by progressively weaker magnetic field dependence of Jc on increasing cf. Accordingly, the crossover field B* at which the pinning force density Fp reaches its maximum value Fpmax = JcB* and the irreversibility field Birr(Fp 0) increase approximately linearly with cf. Therefore, Jc-B and Fp-B variations for all tapes with vortex pinning dominated by fission tracks show universal scaling behaviour with the scaling parameter B* (proportional to cf). Taking into account the adverse effects of c and f on Jc of our tapes, we estimate a maximum B* and Birr that can be reached in 235U-oxide doped Bi2223 tapes at 77 K.

    Full Text Available This paper presents about the transmission of Digital Video Broadcasting system with streaming video resolution 640x480 on different IQ rate and modulation. In the video transmission, distortion often occurs, so the received video has bad quality. Key frames selection algorithm is flexibel on a change of video, but on these methods, the temporal information of a video sequence is omitted. To minimize distortion between the original video and received video, we aimed at adding methodology using sequential distortion minimization algorithm. Its aim was to create a new video, better than original video without significant loss of content between the original video and received video, fixed sequentially. The reliability of video transmission was observed based on a constellation diagram, with the best result on IQ rate 2 Mhz and modulation 8 QAM. The best video transmission was also investigated using SEDIM (Sequential Distortion Minimization Method and without SEDIM. The experimental result showed that the PSNR (Peak Signal to Noise Ratio average of video transmission using SEDIM was an increase from 19,855 dB to 48,386 dB and SSIM (Structural Similarity average increase 10,49%. The experimental results and comparison of proposed method obtained a good performance. USRP board was used as RF front-end on 2,2 GHz.

      Deficits in balance have been identified as a possible risk factor for knee injuries in athletes. Despite a lack of evidence for its effectiveness, kinesiology tape (KT) is widely used to prevent knee injuries.   To investigate the influence of KT at the knee joint on balance ability in healthy men after eccentric exercise.   Crossover study.   University laboratory.   Twelve young men with no history of lower limb injury volunteered for the study (age = 23.3 ± 2.6 years). All participants were students enrolled in a sports science program.   Participants performed the balance test with and without KT at the knee joint on 2 separate days.   The ability to maintain balance was assessed during a single-legged-stance test using a computerized balance-stability test system. The test was performed before and after 30 minutes of downhill walking on a treadmill.   Eccentric exercise resulted in a deterioration of balance ability, which was attenuated by the use of KT. Further analyses revealed that the effectiveness of KT depended on the participant's balance status, with the preventive effect being greater in participants presenting with poorer baseline balance ability.   Applied to the knee joint, KT counteracted the exercise-related deterioration of balance ability observed when no tape was used. Participants presenting with below-average balance ability received more benefit from KT. By preventing exercise-related impairment of balance ability, KT might help to reduce the risk of sport-associated knee injuries.

    Controversy and concern surround the video game playing fascination of children. Scientific reports have explored the negative effects of video games on youth, with a growing number recognizing the actual physical implications of this activity. We offer another reason to discourage children's focus on video games: knuckle pads. A 13-year-old black boy presented with an asymptomatic, slightly hyperpigmented plaque over his right second distal interphalangeal joint. A punch biopsy specimen confirmed knuckle pad as the diagnosis, and a traumatic etiology from video game playing was suspected. Knuckle pads can be painful, cosmetically unappealing, and refractory to treatment. They can now be recognized as yet another potential adverse consequence of chronic video game playing.

    A foundation for distributed source coding was established in the classic papers of Slepian-Wolf (SW) [1] and Wyner-Ziv (WZ) [2]. This has provided a starting point for work on Distributed Video Coding (DVC), which exploits the source statistics at the decoder side offering shifting processing...... steps, conventionally performed at the video encoder side, to the decoder side. Emerging applications such as wireless visual sensor networks and wireless video surveillance all require lightweight video encoding with high coding efficiency and error-resilience.

    Full Text Available The highly efficient and robust stitching of aerial video captured by unmanned aerial vehicles (UAVs is a challenging problem in the field of robot vision. Existing commercial image stitching systems have seen success with offline stitching tasks, but they cannot guarantee high-speed performance when dealing with online aerial video sequences. In this paper, we present a novel system which has an unique ability to stitch high-frame rate aerial video at a speed of 150 frames per second (FPS. In addition, rather than using a high-speed vision platform such as FPGA or CUDA, our system is running on a normal personal computer. To achieve this, after the careful comparison of the existing invariant features, we choose the FAST corner and binary descriptor for efficient feature extraction and representation, and present a spatial and temporal coherent filter to fuse the UAV motion information into the feature matching. The proposed filter can remove the majority of feature correspondence outliers and significantly increase the speed of robust feature matching by up to 20 times. To achieve a balance between robustness and efficiency, a dynamic key frame-based stitching framework is used to reduce the accumulation errors. Extensive experiments on challenging UAV datasets demonstrate that our approach can break through the speed limitation and generate an accurate stitching image for aerial video stitching tasks.

    The Nutrition Communication Project has overseen production of a training video interpersonal communication for health workers involved in growth monitoring and promotion (GMP) programs in Latin America entitled Comuniquemonos, Ya] Producers used the following questions as their guidelines: Who is the audience?, Why is the training needed?, and What are the objectives and advantages of using video? Communication specialists, anthropologists, educators, and nutritionists worked together to write the script. Then video camera specialists taped the video in Bolivia and Guatemala. A facilitator's guide complete with an outline of an entire workshop comes with the video. The guide encourages trainees to participate in various situations. Trainees are able to compare their interpersonal skills with those of the health workers on the video. Further they can determine cause and effect. The video has 2 scenes to demonstrate poor and good communication skills using the same health worker in both situations. Other scenes highlight 6 communication skills: developing a warm environment, asking questions, sharing results, listening, observing, and doing demonstration. All types of health workers ranging from physicians to community health workers as well as health workers from various countries (Guatemala, Honduras, Bolivia, and Ecuador) approve of the video. Some trainers have used the video without using the guide and comment that it began a debate on communication 's role in GMP efforts.

  3. Use of Kinesio-Taping in the Management of Hallux Rigidus: A Case Report

    2017-03-01

    Full Text Available Hallux rigidus is a progressive degenerative disease of the first metatarsophalangeal joint. It is characterized by pain, limitation of the metatarsophalangeal joint motion, mainly dorsiflexion, progressive osteophyte formation and functional impairment. Although there have been many studies concerning non-operative management of hallux rigidus, no research has yet examined the effects of kinesio-taping in hallux rigidus. We present a 57-year-old woman with pain and stiffness around the big toe while walking, and functional insufficiency. The patient received kinesio-taping combined with therapeutic exercise. Pain intensity, range of motion (ROM, functional status were used as the outcome measures. According to the results, kinesio-taping may help reduce pain, increase the range of motion and functional levels in patients with hallux rigidus.

    Solvent lamination for alumina green tapes is readily accomplished using a mixture of ethanol, toluene and poly(propylene glycol). After lamination, the PPG is clearly present as a discrete film at the interface between the laminated tapes. This condition, however, does not generate delamination during firing. Systematic sets of experiments are undertaken to determine the role of PPG in the lamination process and, specifically, the mechanism by which it is redistributed during subsequent processing. PPG slowly diffuses through the organic binder film at room temperature. The PPG diffusion rapidly increases as temperature is increased to 80 C. The key to the efficiency of adhesives during green-tape lamination is mutual solubility of the nonvolatile component of the glue and the base polymeric binder.

    Pediatric cerebral palsy is a non-progressive neurological disorder. It is one of the most common causes of disability among children. Numerous physical therapy techniques are currently used for treatment, and kinesio taping is one of them. The main objective of this study was to review the outcomes of using kinesio taping in published scientific studies conducted in pediatric patients with cerebral palsy and determine their methodological quality. The main scientific databases and the studies published in the official site of the Asociación Española de Vendaje Neuromuscular (Spanish Association for Neuromuscular Taping) were reviewed. Nine studies were included, which provided important outcomes. These studies show the effectiveness of recovering upper limb and motor function and solving dysphagia, which could be present in these patients, although scientific evidence may expand due to improvements in methodology.

    This study was to investigate the effects of prophylactic Kinesio taping and athletic taping on the functional performance of the lower extremities in healthy collegiate players with tapes applied to the dominant leg. The study design was a prospective, randomized, clinical trial with comparison of groups. The 32 healthy collegiate players who participated in this study were randomly assigned to 2 groups, an athletic taping group and a Kinesio taping group. Active range of motion of ankle joint, ankle plantar-flexor strength, endurance, vertical jump performance, and dynamic balance were used to measure the player's functional performance of the lower extremities. These tests were conducted 2 times at 4-hour intervals before and after different tapes were applied. The repeated measures analysis of variance was used to examine the interaction in functional performance between the groups before and after the tapes applied. The results found less limitation of range of motion in active ankle dorsiflexion and significant improvement in dynamic balance in the Kinesio taping group (F = 5.150, P = 0.031, F = 18.766, P taping group. The prophylactic Kinesio taping could enhance dynamic balance and result in less restriction of range of motion of ankle dorsiflexion in healthy collegiate players.

    2014-01-01

    Initial patient perceptions of rhinoplasty results are complicated by early postoperative edema, ecchymosis, and distortion. Anecdotal evidence suggests that taping the nose immediately upon splint removal aids with the patient's psychological adjustment to his or her new appearance. The authors attempt to assess the overall impact of taping after splint removal on patient well-being while providing statistical validation regarding the utility of this intervention. The authors evaluated the reaction of 24 postoperative rhinoplasty patients on the day of splint removal by photographing them and noting their verbal responses. Those patients who were obviously happy received no taping and were dismissed from the study. The remainder of the patients received flesh-colored tape (3M, St Paul, Minnesota) and their subsequent reactions were noted and photographed. Of 24 consecutive patients, 16 received tape. Fifteen of those taped initially displayed a flat affect (group A), while 1 was clearly unhappy (group B). The remaining 8 patients were obviously happy (group C) and were excluded from taping. Thirteen (86%) of those in group A displayed immediate subjective improvement after taping (χ(2) = 12.8; P tape immediately upon splint removal after rhinoplasty improves initial patient perceptions. Taping can provide a simple and risk-free intervention for patients who do not express immediate satisfaction.

    It has been reported that there is high rate of Achilles tendon injury among kendo athletes. For protection and support the area, kendo athletes habitually use taping during practice or games. To investigate the effect of various taping techniques on injury prevention and functional performance in kendo athletes. Case-control study. Laboratory. Fifteen University Kendo Team athletes with at least 2 years kendo experience. Athletes completed 5 stepping backwards and striking cycles under four taping conditions: No taping; Athletic taping of ankle joint (AT-Ankle); Athletic taping of Achilles tendon (AT-Achilles); and Kinesio-Tex taping of Achilles tendon (KT-Achilles). Jump distance, lower limb angular motion, left foot-ground contact time, Achilles tendon force (ATF), and soleus and medial gastrocnemius muscle activities. Lowest peak ATF was found in AT-Achilles during heel-down phase, statistically significantly different from KT-Achilles peak force. Significant decline of soleus muscle EMG amplitude was also found when compared to No taping, during heel-down phase and other conditions during pushing phase. Conversely, KT-Achilles showed significant decrease in foot-ground contact time compared with No taping and greater ankle range of motion than in AT-Ankle. To protect the Achilles tendon, AT-Achilles taping is recommended since it tends to decrease ATF. Conversely, to enhance athletes' performance, we recommend KT-Achilles taping to speed up kendo striking motion. However, the Achilles tendon must withstand greatest forces concurrently. This finding implies that AT-Achilles taping can protect the injured Achilles tendon and KT-Achilles taping can enhance performance on the kendo striking motion.

    Taping techniques that aim to protect and reduce stress on an injured tissue during rehabilitation are common in sport. Called deloading tape, the mechanism of action is hypothesized to involve effects ranging from direct mechanical deloading of the underlying soft tissues to psychological effects on confidence. There is no evidence that deloading tape has direct mechanical effects. This study used an elastographic technique (supersonic shear imaging) to test the hypothesis that deloading tape applied to the skin over the rectus femoris would reduce stress within the taped area of this muscle. Thirteen healthy volunteers participated in this experiment. Muscle shear elastic modulus was compared between three treatments (no tape, deloading tape, and sham tape) in four conditions: three conditions without muscle contraction at different rectus femoris muscle-tendon unit lengths (moderately stretched, highly stretched, and shortened) and during submaximal isometric leg extension. Although there was no effect of treatment when the muscle was shortened (P = 0.99), the shear elastic modulus was significantly affected by treatment for the three other conditions (all P elastic modulus was significantly less during application of deloading tape than that during both the no tape and sham tape conditions (all P ≤ 0.001; e.g., vs no tape: moderately stretched, 8.4 ± 2.7 vs 6.7 ± 1.7 kPa; highly stretched, 25.2 ± 8.2 vs 14.4 ± 4.3 kPa; submaximal contraction, 21.3 ± 4.8 vs 14.2 ± 4.3 kPa). Through the use of elastography, this is the first study to support the hypothesis that deloading tape reduces stress in the underlying muscle region, thereby providing a biomechanical explanation for the effect observed during rehabilitation in clinical practice (reduce pain, restore function, and aid recovery). Further investigations are necessary to confirm these results in injured tissues.

    Full Text Available Midurethral placement of tension-free vaginal tapes with a transvaginal route for stress urinary incontinence achieves higher and better long-term success rates than the transobturator route. Bladder perforations are reported more in transvaginal tape (TVT but incidences of vaginal erosions, extrusion, and groin pain are exceedingly more in TOT groups. There is no clear evidence that transobturator tape (TOT is associated with less post-operative voiding problems than TVT. Major complications such as bowel injuries and significant vascular injuries with TVT are rare. TVT has been found to be superior to TOT and preferable in technically demanding conditions such as prior anti-incontinence operation failures, obese women, and very elevated and scarred lateral cul-de sac. TVT is always preferred in severe grades of stress urinary incontinence and with patients of intrinsic sphincter deficiency (ISD with little or no urethral mobility.

    Prophylactic ankle taping (PAT) is commonly used in sport. Prophylactic ankle taping may restrict ankle motion, which would affect the kinetic chain and alter gait. The purpose of this study was to examine the effects of PAT on lower extremity (LE) kinematics and running economy during treadmill running. Twelve recreational runners (9 women, 3 men; M ± SD age = 31.33 ± 8.04 years, height = 1.67 ± 0.81 m, mass = 61.84 ± 9.38 kg) completed two 20-minute running sessions (PAT and no tape: control [CON]) at a self-selected pace. Before each run, reflective markers were placed along the right side of the body. Sagittal plane kinematic data (60 Hz) were captured 4 times, and expired gases were measured for 2-minute after each video capture during both trials. Stride frequency, stride length, LE kinematic variables at initial contact and end contact (EC) were calculated. Cardiorespiratory variables and heart rate were also measured. Running economy was normalized to oxygen uptake per unit body mass per kilometer (milliliter per kilogram per kilometer) as running speeds varied. At EC, the PAT hip angle significantly decreased (p = 0.01) by 3.82°, whereas CON decreased by 0.85°. The range of motion tended to decrease over the 20-minute run (p = 0.08). Heart rate significantly increased over time (6.7%) but was not different between conditions. Prophylactic ankle taping did not significantly affect the physiological measures associated with the metabolic cost of treadmill running or the other kinematic variables. These findings suggest that the hip angle continued to decrease during the PAT condition at push-off in recreational runners without impacting the metabolic cost of transport.

    Full Text Available The aim of this paper is to present video quality prediction models for objective non-intrusive, prediction of H.264 encoded video for all content types combining parameters both in the physical and application layer over Universal Mobile Telecommunication Systems (UMTS networks. In order to characterize the Quality of Service (QoS level, a learning model based on Adaptive Neural Fuzzy Inference System (ANFIS and a second model based on non-linear regression analysis is proposed to predict the video quality in terms of the Mean Opinion Score (MOS. The objective of the paper is two-fold. First, to find the impact of QoS parameters on end-to-end video quality for H.264 encoded video. Second, to develop learning models based on ANFIS and non-linear regression analysis to predict video quality over UMTS networks by considering the impact of radio link loss models. The loss models considered are 2-state Markov models. Both the models are trained with a combination of physical and application layer parameters and validated with unseen dataset. Preliminary results show that good prediction accuracy was obtained from both the models. The work should help in the development of a reference-free video prediction model and QoS control methods for video over UMTS networks.

    Laser assisted tape winding (LATW) has become more and more popular way of producing new thermoplastic products such as ultra-deep sea water riser, gas tanks, structural parts for aerospace applications. Predicting the temperature in LATW has been a source of great interest since the temperature at nip-point plays a key role for mechanical interface performance. Modeling the LATW process includes several challenges such as the interaction of optics and heat transfer. In the current study, numerical modeling of the optical behavior of laser radiation on circular surfaces is investigated based on a ray tracing and non-specular reflection model. The non-specular reflection is implemented considering the anisotropic reflective behavior of the fiber-reinforced thermoplastic tape using a bidirectional reflectance distribution function (BRDF). The proposed model in the present paper includes a three-dimensional circular geometry, in which the effects of reflection from different ranges of the circular surface as well as effect of process parameters on temperature distribution are studied. The heat transfer model is constructed using a fully implicit method. The effect of process parameters on the nip-point temperature is examined. Furthermore, several laser distributions including Gaussian and linear are examined which has not been considered in literature up to now.

    Objectives. To conduct a systematic review comparing the effects of Kinesio taping with McConnell taping as a method of conservative management of patients with patellofemoral pain syndrome (PFPS). Methods. MEDLINE, PUBMED, EMBASE, AMED, and the Cochrane Central Register of Control Trials electronic databases were searched through July 2014. Controlled studies evaluating the effects of Kinesio or McConnell taping in PFPS patients were retrieved. Results. Ninety-one articles were selected from the articles that were retrieved from the databases, and 11 articles were included in the analysis. The methods, evaluations, and results of the articles were collected, and the outcomes of patellar tapings were analyzed. Kinesio taping can reduce pain and increase the muscular flexibility of PFPS patients, and McConnell taping also had effect in pain relief and patellar alignment. Meta-analysis showed small effect in pain reduction and motor function improvement and moderate effect in muscle activity change among PFPS patients using Kinesio taping. Conclusions. Kinesio taping technique used for muscles can relieve pain but cannot change patellar alignment, unlike McConnell taping. Both patellar tapings are used differently for PFPS patients and substantially improve muscle activity, motor function, and quality of life.

    To investigate the effects of the kinesio tape application to the tibialis anterior on rehabilitation outcomes of the stroke patients. Twenty patients with stroke were allocated into two groups: the first group of ten patients was assigned to receive kinesio tape in addition to the conventional rehabilitation program while a second group of 10 patients was assigned to receive a conventional rehabilitation program only. The clinical variables and health-related quality of life (HRQoL) were evaluated at baseline and at the end of the forth week. The present study showed that kinesio tape application to the tibialis anterior has significant effects on motor recovery of the lower extremity, spasticity, ambulation capacity, HRQoL and gait compared to the control group and baseline. The results of this study suggest that kinesio tape can be used as an ankle training method. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. Color spaces in digital video

    Energy Technology Data Exchange (ETDEWEB)

    Gaunt, R.

    1997-05-01

    Whether it`s photography, computer graphics, publishing, or video; each medium has a defined color space, or gamut, which defines the extent that a given set of RGB colors can be mixed. When converting from one medium to another, an image must go through some form of conversion which maps colors into the destination color space. The conversion process isn`t always straight forward, easy, or reversible. In video, two common analog composite color spaces are Y`tjv (used in PAL) and Y`IQ (used in NTSC). These two color spaces have been around since the beginning of color television, and are primarily used in video transmission. Another analog scheme used in broadcast studios is Y`, R`-Y`, B`-Y` (used in Betacam and Mll) which is a component format. Y`, R`-Y`,B`-Y` maintains the color information of RGB but in less space. From this, the digital component video specification, ITU-Rec. 601-4 (formerly CCIR Rec. 601) was based. The color space for Rec. 601 is symbolized as Y`CbCr. Digital video formats such as DV, Dl, Digital-S, etc., use Rec. 601 to define their color gamut. Digital composite video (for D2 tape) is digitized analog Y`UV and is seeing decreased use. Because so much information is contained in video, segments of any significant length usually require some form of data compression. All of the above mentioned analog video formats are a means of reducing the bandwidth of RGB video. Video bulk storage devices, such as digital disk recorders, usually store frames in Y`CbCr format, even if no other compression method is used. Computer graphics and computer animations originate in RGB format because RGB must be used to calculate lighting and shadows. But storage of long animations in RGB format is usually cost prohibitive and a 30 frame-per-second data rate of uncompressed RGB is beyond most computers. By taking advantage of certain aspects of the human visual system, true color 24-bit RGB video images can be compressed with minimal loss of visual information

    Adhesive tape is commonly used in crimes and is often the subject of forensic evaluation. DNA analysis of adhesive tape can provide DNA profiles of suspects. The object of this study was to evaluate the applicability of DNA analysis on adhesive tape samples in forensic casework. We retrospectively reviewed all cases involving adhesive tape or similar items received by our institute for DNA analysis during the past 11 years. From 100 forensic cases reviewed, 150 adhesive tape samples were examined. A total of 98 DNA profiles were obtained from these samples. Sixty-two of the profiles provided feasible case-relevant information. In conclusion, DNA profiling of adhesive tape samples can be useful in a variety of forensic cases. © 2012 American Academy of Forensic Sciences.

    in reversible computing theory are about multitape machines with two or more tapes, but it is non-obvious what these results imply for reversible complexity theory. Here, we study how the time complexity of multitape RTMs behaves under reductions to one and two tapes. For deterministic Turing machines......Studies of reversible Turing machines (RTMs) often differ in their use of static resources such as the number of tapes, symbols and internal states. However, the interplay between such resources and computational complexity is not well-established for RTMs. In particular, many foundational results......, it is known that the reduction from k tapes to 1 tape in general leads to a quadratic increase in time. For k to 2 tapes, a celebrated result shows that the time overhead can be reduced to a logarithmic factor. We show that identical results hold for multitape RTMs. This establishes that the structure...

    Context: Athletic taping skills are highly valued clinical competencies in the athletic therapy and training profession. The Technical Skill Assessment Instrument (TSAI) has been content validated and tested for intrarater reliability. Objective: To test the reliability of the TSAI using a more robust measure of reliability, generalizability theory, and to hypothetically and mathematically project the optimal number of raters and scenarios to reliably measure athletic taping skills in the future. Setting: Mount Royal University. Design: Observational study. Patients or Other Participants: A total of 29 university students (8 men, 21 women; age = 20.79 ± 1.59 years) from the Athletic Therapy Program at Mount Royal University. Intervention(s): Participants were allowed 10 minutes per scenario to complete prophylactic taping for a standardized patient presenting with (1) a 4-week-old second-degree ankle sprain and (2) a thumb that had been hyperextended. Two raters judged student performance using the TSAI. Main Outcome Measure(s): Generalizability coefficients were calculated using variance scores for raters, participants, and scenarios. A decision study was calculated to project the optimal number of raters and scenarios to achieve acceptable levels of reliability. Generalizability coefficients were interpreted the same as other reliability coefficients, with 0 indicating no reliability and 1.0 indicating perfect reliability. Results: The result of our study design (2 raters, 1 standardized patient, 2 scenarios) was a generalizability coefficient of 0.67. Decision study projects indicated that 4 scenarios were necessary to reliably measure athletic taping skills. Conclusions: We found moderate reliability coefficients. Researchers should include more scenarios to reliably measure athletic taping skills. They should also focus on the development of evidence-based practice guidelines and standards of athletic taping and should test those standards using a

    Video games are widely practiced. Questions about their potential health risks arise, including the risk of addiction. If there is at present no official diagnosis of video games addiction, the DSM-5 proposes temporary criteria based on pathological gambling. Video game addiction affects a minority of at risk individuals. The proposed treatments are essentially psychotherapeutic. Video games practices can be non problematic and they may also have potential beneficial effects on individuals. It is therefore recommended, when assessing video games practices, to take into account the positive and negative impacts of their use.

    Objective: The aim of the study was to investigate the effects of shoulder and scapular region rigid taping and kinesio taping on scapular dyskinesis and pectoralis minor shortness in overhead athletes. Method: This study included 72 overhead athletes. The athletes were randomly divided into four groups: kinesio taping (shoulder and scapular region) was applied to Kinesio Taping Group (KB), rigid taping (shoulder and scapular region) was applied to Rigid Taping Group (RB), placebo kinesio taping was applied to Placebo Taping Group (PB). Control group received no tape. Demographic data of overhead athletes, anthropometric characteristics, pain severity and injury background were evaluated before taping. Pectoralis minor shortness (Pectoralis Minor Index) and scapular dyskinesis (Scapular Dyskinesis Test) were evaluated before taping, immediately after (30-minutes) taping and after 48 hours of use within 12-24 hours. Control group was evaluated at the same periods. Results: Before taping; demographic, anthropometric and sports-related characteristics were similar in groups and there was no statistically difference (p>0.05). It was determined that Pectoralis Minor Index (PMI) and scapular dyskinesis improved immediately after taping and after 48 hours of use in KB and RB (ptaping for PMI among groups (p>0.05). Conclusion: Kinesio taping and rigid taping seems to have positive effects on scapular dyskinesis and pectoralis minor shortness in overhead athletes. Future studies on larger sample size are needed to verify the differences of the effects of these taping techniques between placebo or controls.

    Postoperative pain and severe side effects of opioid analgesics present a clinical challenge after cardio-thoracic surgery. In this study, the impact of Kinesio® taping on postoperative morbidity after median sternotomy was observed. Thirty-nine patients (mean age 66 ± 9 years, CI: 63.28; 68.98) who underwent median sternotomy between 09/2014 and 11/2014 participated in this prospective randomized controlled trial. Patients were assigned into a treatment on a non-treatment group. Patients in the treatment group were taped after leaving the intensive care unit. We assessed, pain, consumption of pain medication, the subjective estimation of patients' ability to breathe, radiologic and microbial abnormalities as well as adverse effects resulting from the tape use daily until discharge. To determine the patients' satisfaction a discharge questionnaire was offered after completion of data. Patients who were treated with tape report significantly less pain (2.14 ± 0.5, CI: 1.1; 3.13) than patients from the control group (4.16 ± 0.6, CI: 2.92; 5.41, p = 0.01). The need for opioid pain medication, as assessed by total analgesic consumption per patient, was significantly less in the treatment group (1.2 ml ± 0.4 ml, CI: 0.40 ml; 2.01 ml) versus (3.1 ml ± 0.5 ml, CI: 2.0 ml; 4.2 ml, p = 0.01). The subjective estimation of patients' ability to breathe was significantly better (p Kinesio® tape group compared to the control group. Taped patients had a mean hospitalization of 10 ± 1 day (CI: 8.74 days; 11.78 days) untapped patients stayed for 11 ± 1 days (CI: 9.17 days; 11.83 days). Adverse effects from the tape treatment were not observed. Kinesio® taping after median sternotomy is a low-risk, non-pharmacologic, cost effective, and promising method for improving patients' breathing conditions, reducing postoperative pain, pain medication consumption, and thus, potential adverse effects of analgesics.

    To observe postural characteristics of female dressage riders, through application of three-dimensional motion analysis and to assess the effects of athletic taping on postural asymmetry during sitting trot. Randomised cross-over. Data collection took place at Myerscough Agricultural College in an indoor riding area. Ten healthy female experienced dressage riders participated. Movement kinematics of the trunk and pelvis, pre and post taping intervention. Riders presented pre-intervention with asymmetric movement characteristics through dynamic observation of trunk and pelvic postures during sitting trot. There was a significant increase (p ≤ 0.05) in the range (°) of trunk lateral-flexion following tape intervention applied over the thoracic spine. This study supports the quantification of dynamic postural characteristics of dressage athletes by three-dimensional motion analysis. Asymmetrical postures occur within dressage riders when performing sitting trot. The application of tape to 'align' asymmetry altered riders' postures. Taping over the thoracic region resulted in a compensatory increase in motion through the lumbar region. Clinicians should approach the application of postural taping with an awareness of the restrictive mechanisms of tape. Findings may help clinicians determine whether technique/type of tape applied is suitable for achieving marginal gains in the alignment of posture in competitive dressage athletes.

    Background information The present study aimed to investigate the effects of Kinesio Taping on the trajectory of the forelimb and the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses. 19 horses and ponies of different breeds (body weight: 496±117 kg), gender (8 mares, 10 geldings and 3 stallions) and ages (14.9±6.9 years old) were analysed without Kinesio Tape (“no tape”), with Kinesio Tape (muscle facilitation application on both muscles of both sides, “with tape”) and immediately after Kinesio Taping (“post tape”) through kinematic motion analysis and surface electromyography on a treadmill at the walk (speed: 1.5±0.1 m/s) and trot (speed: 3.1±0.3 m/s). Results The results of the surface electromyography (maximum muscle activity at the walk and trot) and the kinematic motion analysis (maximum stride length and maximum height of the forelimbs flight arc at the walk and trot) showed that there were no significant differences between "no tape", "with tape" and "post tape". Conclusion To sum up, Kinesio Taping on the M. brachiocephalicus and the M. extensor carpi radialis does not affect (in a positive or negative manner) the trajectory of the forelimb or the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses.

    The mesoscopic stress and strain states of Bi2223/Ag/Ag-alloy superconducting composite tapes have been studied both analytically and experimentally under bending deformation. The tapes used in the present study were supplied as the standard samples for the VAMAS round-robin program (classified as VAM1 and VAM3). Detailed tape bending analysis was completed based on a damage-free initial state, and the calculated decrease of critical current, Ic, due to Bi2223 filament fracture was compared to the experimental Ic decrease. The calculated Ic was much lower than that obtained in the experiments for both tapes. Metallography indicated the presence of delamination in as-received as well as bend-tested tapes. The analysis was therefore modified to include delamination and it was completed for the case where delamination occupied the full width of the tape mid-plane. The calculated Ic with delamination was higher than the experimental results for both tapes. Delamination occupying partial width of the mid-plane explained this difference. Finally, the width ratio where delamination exists was calculated by comparing the analytical results with delamination and experimental results. This ratio increased with increasing curvature of the tape.

    The purpose of this study was to compare the effect of elastic tape (Kinesio tape) to placebo tape or static stretching on delayed onset muscle soreness. Fifty-one untrained female healthy volunteers were randomly assigned into three groups (n = 17/group), elastic tape, placebo tape and stretching group. Muscle soreness was induced by 4 sets of 25 maximal isokinetic (60°.s -1 ) eccentric contractions of dominant quadriceps on an isokinetic dynamometer. Compared with placebo tape, the elastic tape participants had less muscle soreness at 72 h post-exercise (p = 0.01). The elastic tape also increased isometric strength at 72 h post-exercise compared with the placebo (p = 0.03) and stretching group (p = 0.02). However, there was little effect between groups for changes in thigh circumference, jumping, pressure pain threshold, rate of perceived exertion, creatine kinase activity and joint motion. Elastic taping increased muscle strength recovery and reduced muscle soreness after intensive exercise.

    The article presents a numerical analysis of turbulent periodic flow and heat transfer characteristics in a five-start spiral corrugated tube combined with five-channel twisted tape. Influences of the five-channel twisted tape with tape width ratio, w/D=0.10, 0.20, 0.30, 0.40 and 0.44 at constant the twisted length ratio, y/D=2.0 were described. The results were reported in term of flow structure, temperature distribution, TKE field, local Nusselt number distribution on the wall, Nusselt number ratio, friction factor ratio and thermal enhancement factor. The five-start spiral corrugated tube combined with five-channel twisted tape showed a main swirl flow and secondary swirl flow along the tube due to the induction of the spiral groove while the smooth circular tube appeared the straight only and the five-start spiral corrugated tube with the five-channel twisted tape at w/D=0.44 appeared the main swirl flow only. The swirl flow help to increase fluid mixing and increase in heat transfer rate over the smooth circular tube. The increase in the w/D lead to the rise of Nusselt number and friction factor. The result showed that the optimum thermal enhancement factor of about 1.16was found at the five-start spiral corrugated tube without the five-channel twisted tape and at w/D=0.44.

    Full Text Available As the public education system in Northern Ontario continues to take a downward spiral, a plethora of secondary school students are being placed in an alternative educational environment. Juxtaposing the two educational settings reveals very similar methods and characteristics of educating our youth as opposed to using a truly alternative approach to education. This video reviews the relationship between public education and alternative education in a remote Northern Ontario setting. It is my belief that the traditional methods of teaching are not appropriate in educating at risk students in alternative schools. Paper and pencil worksheets do not motivate these students to learn and succeed. Alternative education should emphasize experiential learning, a just in time curriculum based on every unique individual and the students true passion for everyday life. Cameron Culbert was born on February 3rd, 1977 in North Bay, Ontario. His teenage years were split between attending public school and his willed curriculum on the ski hill. Culbert spent 10 years (1996-2002 & 2006-2010 competing for Canada as an alpine ski racer. His passion for teaching and coaching began as an athlete and has now transferred into the classroom and the community. As a graduate of Nipissing University (BA, BEd, MEd. Camerons research interests are alternative education, physical education and technology in the classroom. Currently Cameron is an active educator and coach in Northern Ontario.

  11. Multiview video codec based on KTA techniques

    2011-03-01

    Multi-view video coding (MVC) is a video coding standard developed by MPEG and VCEG for multi-view video. It showed average PSNR gain of 1.5dB compared with view-independent coding by H.264/AVC. However, because resolutions of multi-view video are getting higher for more realistic 3D effect, high performance video codec is needed. MVC adopted hierarchical B-picture structure and inter-view prediction as core techniques. The hierarchical B-picture structure removes the temporal redundancy, and the inter-view prediction reduces the inter-view redundancy by compensated prediction from the reconstructed neighboring views. Nevertheless, MVC has inherent limitation in coding efficiency, because it is based on H.264/AVC. To overcome the limit, an enhanced video codec for multi-view video based on Key Technology Area (KTA) is proposed. KTA is a high efficiency video codec by Video Coding Expert Group (VCEG), and it was carried out for coding efficiency beyond H.264/AVC. The KTA software showed better coding gain than H.264/AVC by using additional coding techniques. The techniques and the inter-view prediction are implemented into the proposed codec, which showed high coding gain compared with the view-independent coding result by KTA. The results presents that the inter-view prediction can achieve higher efficiency in a multi-view video codec based on a high performance video codec such as HEVC.

    2017-10-01

    Continuous welding techniques like thermoplastic tape placement with in situ consolidation offer several advantages over traditional manufacturing processes like autoclave consolidation, thermoforming, etc. However, still there is a need to solve several important processing issues before it becomes a viable economic process. Intensive process analysis and optimization has been carried out in the past through experimental investigation, model definition and simulation development. Today process simulation is capable to predict resulting consolidation quality. Effects of material imperfections or process parameter variations are well known. But using this knowledge to control the process based on online process monitoring and according adaption of the process parameters is still challenging. Solving inverse problems and using methods for automated code generation allowing fast implementation of algorithms on targets are required. The paper explains the placement technique in general. Process-material-property-relationships and typical material imperfections are described. Furthermore, online monitoring techniques and how to use them for a model based process control system are presented.

  4. Are violent video games harmful?

    Science.gov (United States)

    Porter, Guy; Starcevic, Vladan

    2007-10-01

    The aim of this paper is to revisit the controversial issue of the association of violent video games and aggressive behaviour. Several lines of evidence suggest that there is a link between exposure to violent video games and aggressive behaviour. However, methodological shortcomings of research conducted so far make several interpretations of this relationship possible. Thus, aggressive behaviour may be a consequence of playing violent video games, an expression of hostile traits that existed before exposure to these games, and/or it may be a result of several possible combinations of these and other factors. Mental health professionals need to be aware of these potentially negative effects of violent video games when assessing patients who present with aggression. There is a need for prospective, long-term studies similar to those evaluating the effects of television and film violence on children and adolescents.

    Peru developed its first use of video for training and education in rural areas over a decade ago. On completion of the project in 1986, over 400,000 peasants had attended video courses lasting from 5-20 days. The courses included rural health, family planning, reforestation, agriculture, animal husbandry, housing, nutrition, and water sanitation. There were 125 course packages made and 1,260 video programs from 10-18 minutes in length. There were 780 additional video programs created on human resource development, socioeconomic diagnostics and culture. 160 specialists were trained to produce audiovisual materials and run the programs. Also, 70 trainers from other countries were trained. The results showed many used the training in practical applications. To promote rural development 2 things are needed , capital and physical inputs, such as equipment, fertilizers, pesticides, etc. The video project provided peasants an additional input that would help them manage the financial and physical inputs more efficiently. Video was used because many farmers are illiterate or speak a language different from the official one. Printed guides that contained many illustrations and few words served as memory aids and group discussions reinforced practical learning. By seeing, hearing, and doing, the training was effective. There were 46% women which made fertility and family planning subjects more easily communicated. The production of teaching modules included field investigations, academic research, field recording, tape editing, and experimental application in the field. An agreement with the peasants was initiated before a course began to help insure full participation and to also make sure resources were available to use the knowledge gained. The courses were limited to 30 and the cost per participant was $34 per course.

    This paper presents the measurement and simulation of Alternating Current (AC) losses on the Stabilizer-free and Copper Stabilizer High Temperature Superconducting (HTS) Tapes: SuperPower SF12100 and SCS12050. The AC loss measurement utilised electrical method to obtain overall losses with AC transport currents. The 2D H-formulation by COMSOL Multiphysics has been used to simulate the real geometry and multi-layer HTS tapes. Ferromagnetic AC losses of substrate have been assumed to be ignored as the substrates of SF12100 and SCS12050 are non-magnetic. Hysteresis AC losses in the superconducting layer, and eddy-current AC losses in copper stabilizer, silver overlayer and substrate were concerned in this investigation. The measured AC losses were compared to the AC losses from simulation, with 3 cases of different AC frequency 10, 100, and 1000 Hz. The eddy-current AC losses of copper stabilizer at frequency 1000 Hz were determined from both experiment and simulation. The estimation of AC losses with frequency at 10,000 Hz was also carried out using simulation method. Finally, the frequency dependence of AC losses from Stabilizer-free Tape and Copper Stabilizer Tape were compared and analysed.

    Full Text Available Scoliosis is a lateral curvature of the spine. It is the most common deformity of the immature spine. The essential goal of treatment is to allow patients with scoliosis to avoid cardiopulmonary and neurological problems, and to improve the patient's appearance and future quality of life. Kinesio Taping is a method used for treatment of various musculo-skeletal conditions. The effects of Kinesio Taping is to relieve pain or abnormal feeling on the skin and fascia, supports the muscle in movement, removes congestion of lymphatic fluid or hemorrhages under the skin, and corrects misalignment of the muscle, fascia, and joint. Forty adolescent females complain from scoliosis their ages ranged from 11 to 17 years old, and their BMI was from 15 to 25 kg/m². They were divided randomly into two groups. Group A received therapeutic exercises for scoliosis, while group B received therapeutic exercise in addition to kinesio taping. X ray plain used for measuring of Cobb’s angle and present pain intensity (Ppi for pain assessment before and after treatment. There was a significant reduction of Cobb's angle and pain intensity at post treatment at both groups (p<0.05. There were significant reduction p<0.0001 in Ppi and this significant reduction in favor of group B. There was no significant differences between both groups in Cobb’s angle. Exercises for scoliosis and exercises augmented by kinesio taping had a significant effects on reduction of both Cobb’s angle and pain intensity.

  13. Effects of Kinesio taping on scapular kinematics of overhead athletes following muscle fatigue.

    Zanca, Gisele Garcia; Grüninger, Bruno; Mattiello, Stela Márcia

    2016-08-01

    Scapular kinematics alterations have been found following muscle fatigue. Considering the importance of the lower trapezius in coordinated scapular movement, this study aimed to investigate the effects of elastic taping (Kinesio taping, KT) for muscle facilitation on scapular kinematics of healthy overhead athletes following muscle fatigue. Twenty-eight athletes were evaluated in a crossover, single-blind, randomized design, in three sessions: control (no taping), KT (KT with tension) and sham (KT without tension). Scapular tridimensional kinematics and EMG of clavicular and acromial portions of upper trapezius, lower trapezius and serratus anterior were evaluated during arm elevation and lowering, before and after a fatigue protocol involving repetitive throwing. Median power frequency decline of serratus anterior was significantly lower in KT session compared to sham, possibly indicating lower muscle fatigue. However, the effects of muscle fatigue on scapular kinematics were not altered by taping conditions. Although significant changes were found in scapular kinematics following muscle fatigue, they were small and not considered relevant. It was concluded that healthy overhead athletes seem to present an adaptive mechanism that avoids the disruption of scapular movement pattern following muscle fatigue. Therefore, these athletes do not benefit from the use of KT to assist scapular movement under the conditions tested. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This paper deals with the electrical characteristics of no-insulation coil wound with surface-processed HTS tape. The bypassing current path through turn-to-turn contacts within a coil is formed in the no-insulation coil, and this bypassing current path determines two characteristics: 1) self-protection and 2) charge-discharge delay. The amplitude of bypassing current is determined by contact resistance between the turn-to-turn contacts of the no-insulation coil. The surface roughness of the HTS tape is one of the parameters to change the contact resistance. The HTS tapes were processed to roughen by bead blast and abrasive paper, and the no-insulation coil is fabricated using processed HTS tape. We have studied the charge-discharge delay and self-protecting characteristic of each no-insulation coil by 1) sudden discharge tests and 2) overcurrent tests. The FEM simulations of contact resistance of no-insulation coil were carried out. The contact surface resistance of a case processed by abrasive paper has almost three times larger than that of reference no-insulation coil, and a case processed by bead blast presents almost same contact surface resistance with reference no-insulation coil.

    2011-06-01

    The development of PIT fabrication process of iron pnictide superconducting wires and tapes has been reviewed. Silver was found to be the best sheath material, since no reaction layer was observed between the silver sheath and the superconducting core. The grain connectivity of iron pnictide wires and tapes has been markedly improved by employing Ag or Pb as dopants. At present, critical current densities in excess of 3750 A /cm 2 (I c = 37.5 A) at 4.2 K have been achieved in Ag-sheathed SrKFeAs wires prepared with the above techniques, which is the highest value obtained in iron-based wires and tapes so far. Moreover, Ag-sheathed Sm-1111 superconducting tapes were successfully prepared by PIT method at temperatures as low as ̃ 900 °C, instead of commonly used temperatures of ̃ 1200 °C. These results demonstrate the feasibility of producing superconducting pnictide composite wires, even grain boundary properties require much more attention. © 2010 IEEE.

    Taping is commonly used in the management of several musculoskeletal conditions, including patellofemoral pain syndrome (PFPS). Specific guidelines for taping are unknown. To investigate the efficacy of knee taping in the management of PFPS. Our hypothesis was that tension taping and exercise would be superior to placebo taping and exercise as well as to exercise or taping alone. The PubMed/MEDLINE, Cochrane, Rehabilitation and Sports Medicine Source, and CINAHL databases were reviewed for English-language randomized controlled trials (RCTs) evaluating the efficacy of various taping techniques that were published between 1995 and April 2015. Keywords utilized included taping, McConnell, kinesio-taping, kinesiotaping, patellofemoral pain, and knee. Studies included consisted of RCTs (level 1 or 2) with participants of all ages who had anterior knee or patellofemoral pain symptoms and had received nonsurgical management using any taping technique. Systematic review. Level 2. A checklist method was used to determine selection, performance, detection, and attrition bias for each article. A quality of evidence grading was then referenced using the validated PEDro database for RCTs. Three difference comparison groups were compared: tension taping and exercise versus placebo taping and exercise (group 1), placebo taping and exercise versus exercise alone (group 2), and tension taping and exercise versus taping alone (group 3). Five RCTs with 235 total patients with multiple intervention arms were included. Taping strategies included McConnell and Kinesiotaping. Visual analog scale (VAS) scores indicated improvement in all 3 comparison groups (group 1: 91 patients, 39% of total, mean VAS improvement 44.9 [tension taping + exercise] vs 66 [placebo taping + exercise]; group 2: 56 patients, 24% of total, mean VAS improvement 66 [placebo taping + exercise] vs 47.6 [exercise alone]; and group 3: 112 patients, 48% of total, mean VAS improvement 44.9 [tension taping + exercise

    Full Text Available With the development of heterogeneous networks and video coding standards, multiresolution video applications over networks become important. It is critical to ensure the service quality of the network for time-sensitive video services. Worldwide Interoperability for Microwave Access (WIMAX is a good candidate for delivering video signals because through WIMAX the delivery quality based on the quality-of-service (QoS setting can be guaranteed. The selection of suitable QoS parameters is, however, not trivial for service users. Instead, what a video service user really concerns with is the video quality of presentation (QoP which includes the video resolution, the fidelity, and the frame rate. In this paper, we present a quality control mechanism in multiresolution video coding structures over WIMAX networks and also investigate the relationship between QoP and QoS in end-to-end connections. Consequently, the video presentation quality can be simply mapped to the network requirements by a mapping table, and then the end-to-end QoS is achieved. We performed experiments with multiresolution MPEG coding over WIMAX networks. In addition to the QoP parameters, the video characteristics, such as, the picture activity and the video mobility, also affect the QoS significantly.

    2011-03-01

    In this paper, we present a large database of over 50,000 user-labeled videos collected from YouTube. We develop a compact representation called "tiny videos" that achieves high video compression rates while retaining the overall visual appearance of the video as it varies over time. We show that frame sampling using affinity propagation-an exemplar-based clustering algorithm-achieves the best trade-off between compression and video recall. We use this large collection of user-labeled videos in conjunction with simple data mining techniques to perform related video retrieval, as well as classification of images and video frames. The classification results achieved by tiny videos are compared with the tiny images framework [24] for a variety of recognition tasks. The tiny images data set consists of 80 million images collected from the Internet. These are the largest labeled research data sets of videos and images available to date. We show that tiny videos are better suited for classifying scenery and sports activities, while tiny images perform better at recognizing objects. Furthermore, we demonstrate that combining the tiny images and tiny videos data sets improves classification precision in a wider range of categories.

    Controlled laboratory study. To examine the effect of 2 adhesive tape conditions compared to a no-tape condition on muscle activity of the fibularis longus during a sudden inversion perturbation in male athletes (soccer, team handball, basketball). Ankle sprains are common in sports, and the fibularis muscles play a role in providing functional stability of the ankle. Prophylactic ankle taping with nonelastic sports tape has been used to restrict ankle inversion. Kinesio Tape, an elastic sports tape, has not been studied for that purpose. Fifty-one male premier-league athletes were tested for functional stability of both ankles with the Star Excursion Balance Test. Based on the results, those with the 15 highest and those with the 15 lowest stability scores were selected for further testing. Muscle activity of the fibularis longus was recorded with surface electromyography during a sudden inversion perturbation. Each participant was tested under 3 conditions: ankle taped with nonelastic white sports tape, ankle taped with Kinesio Tape, and no ankle taping. Differences in mean muscle activity were evaluated with a 3-way mixed-model analysis of variance (ANOVA) for the 3 conditions, across four 500-millisecond time frames, and between the 2 groups of stable versus unstable participants. Differences in peak muscle activity and in the time to peak muscle activity were evaluated with a 2-way mixed-model ANOVA. Significantly greater mean muscle activity was found when ankles were taped with nonelastic tape compared to no tape, while Kinesio Tape had no significant effect on mean or maximum muscle activity compared to the no-tape condition. Neither stability level nor taping condition had a significant effect on the amount of time from perturbation to maximum activity of the fibularis longus muscle. Nonelastic sports tape may enhance dynamic muscle support of the ankle. The efficacy of Kinesio Tape in preventing ankle sprains via the same mechanism is unlikely, as it had

    We address the problem of temporally aligning semantically similar videos, for example two videos of cars on different tracks. We present an alignment method that establishes frame-to-frame correspondences such that the two cars are seen from a similar viewpoint (e.g. facing right), while also being temporally smooth and visually pleasing. Unlike previous works, we do not assume that the videos show the same scripted sequence of events. We compare against three alternative methods, including ...

  3. The evolution of the tape measure protein: units, duplications and losses

    2011-10-01

    Full Text Available Abstract Background A large family of viruses that infect bacteria, called phages, is characterized by long tails used to inject DNA into their victims' cells. The tape measure protein got its name because the length of the corresponding gene is proportional to the length of the phage's tail: a fact shown by actually copying or splicing out parts of DNA in exemplar species. A natural question is whether there exist units for these tape measures, and if different tape measures have different units and lengths. Such units would allow us to retrace the evolution of tape measure proteins using their duplication/loss history. The vast number of sequenced phages genomes allows us to attack this problem with a comparative genomics approach. Results Here we describe a subset of phages whose tape measure proteins contain variable numbers of an 11 amino acids sequence repeat, aligned with sequence similarity, structural properties, and simple arithmetics. This subset provides a unique opportunity for the combinatorial study of phage evolution, without the added uncertainties of multiple alignments, which are trivial in this case, or of protein functions, that are well established. We give a heuristic that reconstructs the duplication history of these sequences, using divergent strains to discriminate between mutations that occurred before and after speciation, or lineage divergence. The heuristic is based on an efficient algorithm that gives an exhaustive enumeration of all possible parsimonious reconstructions of the duplication/speciation history of a single nucleotide. Finally, we present a method that allows, when possible, to discriminate between duplication and loss events. Conclusions Establishing the evolutionary history of viruses is difficult, in part due to extensive recombinations and gene transfers, and high mutation rates that often erase detectable similarity between homologous genes. In this paper, we introduce new tools to address this

    Data about the use of tension-free vaginal tape (TVT) in the management of recurrent urodynamic stress incontinence (RUSI) after previous failed midurethral sling procedure (MUSP) are limited. Assessment of the efficacy and the indications of the TVT procedure in the management of patients with RUSI after failed previous MUSP. Thirty-one patients with RUSI after previous failed MUSP were prospectively enrolled at a single tertiary academic center. Preoperatively and postoperatively, patients were assessed with physical examination, urinalysis, urine culture, bladder diary for 2-3 d, Q-tip test, uroflow, filling and voiding cystometry, urethral profilometry, and 1-h pad test. Mean follow-up was at 18.6 mo (range: 12-28 mo). Overall, the objective cure rate based on the pad test findings was 74%, the improvement rate was 6.5%, and the failure rate was 19.5%. The objective cure rate based on cough stress test during filling cystometry was 77.4%, and the subjective cure rate based on patients' answers was 71%. The study could have some limitations. The relatively small number of patients enrolled could affect the findings of study to some degree. Additionally, because urethral pressure profiles show a significant degree of directional dependence when side-hole microtip transducers are used, as in the present study, the orientation of the transducer could affect the values measured. The TVT procedure as a second operation could provide an overall cure rate of 74% with a low complication rate in female patients with RUSI after previous failed midurethral tape procedures.

    2017-06-01

    This paper focuses on debris mitigation in a laser driven tape drive x-ray source. A smart design is being used to minimise the effect of shockwave reflection from the target's back and a continuous rough pumping is utilised to obtain an efficient purging of big lumpy debris particles out of the interaction chamber. The effect of low pressure (3-6 mbar) nitrogen buffer gas is studied together with a moderate magnetic field (0.14 Tesla) on both debris spall and hot ions trajectory. The target material for this work is a 15 μm VHS video tape composed of Mylar as carrier film with Fe2O3 and CrO2 powder. The experiments were conducted using a long pulsed 800ps, 50 Hz Nd: YAG laser. The results obtained appeared to be promising in reducing the damaging effect of large debris particles (between 50 and 140 microns) as well as small particles (~ 5 microns) that deteriorates the efficiency of delicate optics.

    2013-09-01

    Full Text Available Objectives: To analyze the short and long term results of tapes of different materials used to treat stress urinary incontinence (SUI. A secondary objective was to evaluate the ability to adjust the tape after implantation. Materials and methods: Retrospective chart review of 355 patients with SUI operated between March 2003 and October 2011. Eight different types of transobturator tapes were used: Gynecare TVT-O®, Monarc®, SAFYRE®, Contasure KIM®, I-Stop®, DynaMesh®, Aris® Bandellete and Swing-band®. Results and complications were recorded. Results: The mean age at operation was 61 years. Correction of SUI was achieved in 87.88% of cases. The best results were obtained with Contasure KIM® (98.26 % continence. The tape was well tolerated and was elastic enough to be able to be adjusted 48-72 hours after implantation without deformation. Slings with macropores and over lock stiches on the superior and inferior borders presented the lower rates of postoperative urinary retention, pain, perior postoperative bleeding and urinary tract infections. Conclusions: Transobturator tension free tapes require a short operation time and have a low complication rate. The possibility of adjustment in the early postoperative period increases the success rate and reduces complications. Knotless meshes with macropores and over lock stiches appear to be better balanced, are quite resistant to stretching and deformation when readjusted after implantation and present a low infection rate.

    Structural tapes provide comparable toughness as structural adhesives at orders of magnitude lower stresses. This is potentially useful to minimize the effects of differences in thermal expansion in the joining of mixed materials. The strength properties are modelled using the cohesive zone model....... Thus, a cohesive zone represents the tape, i.e. stresses in the tape are transmitted to the substrates through tractions determined by the separations of the surfaces of substrates. This simplification allows for structural analysis of large complex structures. The relation between the traction...

    Book, Michael L.; Bryan, Thomas C.; Howard, Richard T.; Dabney, Richard W.

    1992-01-01

    The Automated Rendezvous and Docking system (ARAD) is composed of two parts. The first part is the sensor which consists of a video camera ringed with two wavelengths of laser diode. The second part is a standard Remote Manipulator System (RMS) target used on the Orbiter that has been modified with three circular pieces of retro-reflective tape covered by optical filters which correspond to one of the wavelengths of laser diode. The sensor is on the chase vehicle and the target is on the target vehicle. The ARAD system works by pulsing one wavelength laser diodes and taking a picture. Then the second wavelength laser diodes are pulsed and a second picture is taken. One picture is subtracted from the other and the resultant picture is thresholded. All adjacent pixels above threshold are blobbed together (X and Y centroids calculated). All blob centroids are checked to recognize the target out of noise. Then the three target spots are windowed and tracked. The three target spot centroids are used to evaluate the roll, yaw, pitch, range, azimuth, and elevation. From that a guidance routine can guide the chase vehicle to dock with the target vehicle with the correct orientation.

    Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character recognition (OCR) technology was enhanced with image transformations for extraction of text from video frames to support indexing and search. The images and text on video frames is analyzed to divide lecture videos into topical segments. The ICS video player integrates indexing, search, and captioning in video playback providing instant access to the content of interest. This video framework has been used by more than 70 courses in a variety of STEM disciplines and assessed by more than 4000 students. Results presented from the surveys demonstrate the value of the videos as a learning resource and the role played by videos in a students learning process. Survey results also establish the value of indexing and search features in a video platform for education. This paper reports on the development and evaluation of ICS videos framework and over 5 years of usage experience in several STEM courses.

    2015-01-01

    Full Text Available This paper presents a comparison study on thermal performance conic cut twist tape inserts in laminar flow of nanofluids through a constant heat fluxed tube. Three tape configurations, namely, quadrant cut twisted tape (QCT, parabolic half cut twisted tape (PCT, and triangular cut twisted (VCT of twist ratio y = 2.93 and cut depth de = 0.5 cm were used with 1% and 2% volume concentration of SiO2/water and TiO2/water nanofluids. Typical twist tape with twist ratio of y = 2.93 was used for comparison. The results show that the heat transfer was enhanced by increasing of Reynolds number and nanoparticles concentration of nanofluid. The results have also revealed that the use of twist tape enhanced the heat transfer coefficient significantly and maximum heat transfer enhancement was achieved by the presence of triangular cut twist tape insert with 2% volume concentration of SiO2 nanofluid. Over the range investigated, the maximum thermal performance factor of 5.13 is found with the simultaneous use of the SiO2 nanofluid at 2% volume concentration VCT at Reynolds number of 220. Furthermore, new empirical correlations for Nusselt number, friction factor, and thermal performance factor are developed and reported.

    Multifactorial, repeated-measures, within-subjects design. To investigate the immediate effects of scapular taping on surface electromyographic (EMG) signal amplitude of shoulder girdle muscles during upper extremity elevation in individuals with suspected shoulder impingement syndrome. Individuals with shoulder impingement syndrome may present with increased activity of the upper trapezius and inhibition of other shoulder muscles active during upper extremity elevation. Scapular taping is theorized to normalize shoulder girdle function during scapular upward rotation by decreasing upper trapezius activity and increasing the activity of the lower trapezius and other muscles. assessed for each muscle. Upper trapezius activity was significantly lower with tape during shelf task elevation (P = .002), especially above 90 degrees (Pshoulder abduction in the scapular plane, the main effect for upper trapezius showed a significant decrease of EMG signal amplitude (P = .047) for tape versus no tape, but no significant interactions were found among components of this activity, or for other muscles. Scapular taping decreased upper trapezius and increased lower trapezius activity in people with suspected shoulder impingement during a functional overhead-reaching task, and decreased upper trapezius activity during shoulder abduction in the scapular plane. Taping did not affect the other muscles under the loads tested, but it is possible that the activity of these muscles was not deficient at the time of testing.

  12. Making Sense of Video Analytics: Lessons Learned from Clickstream Interactions, Attitudes, and Learning Outcome in a Video-Assisted Course

    Directory of Open Access Journals (Sweden)

    Michail N. Giannakos

    2015-02-01

    Full Text Available Online video lectures have been considered an instructional media for various pedagogic approaches, such as the flipped classroom and open online courses. In comparison to other instructional media, online video affords the opportunity for recording student clickstream patterns within a video lecture. Video analytics within lecture videos may provide insights into student learning performance and inform the improvement of video-assisted teaching tactics. Nevertheless, video analytics are not accessible to learning stakeholders, such as researchers and educators, mainly because online video platforms do not broadly share the interactions of the users with their systems. For this purpose, we have designed an open-access video analytics system for use in a video-assisted course. In this paper, we present a longitudinal study, which provides valuable insights through the lens of the collected video analytics. In particular, we found that there is a relationship between video navigation (repeated views and the level of cognition/thinking required for a specific video segment. Our results indicated that learning performance progress was slightly improved and stabilized after the third week of the video-assisted course. We also found that attitudes regarding easiness, usability, usefulness, and acceptance of this type of course remained at the same levels throughout the course. Finally, we triangulate analytics from diverse sources, discuss them, and provide the lessons learned for further development and refinement of video-assisted courses and practices.

  13. Remote sensing of pressure inside deformable microchannels using light scattering in Scotch tape

    CERN Document Server

    Kim, Kyungduk; Koh, Joonyoung; Shin, Jung H; Lee, Wonhee; Park, Yongkeun

    2015-01-01

    We present a simple but effective method to measure the pressure inside a deformable micro-channel using laser scattering in a translucent Scotch tape. Our idea exploits the fact that the speckle pattern generated by a turbid layer is sensitive to the changes in an optical wavefront of an impinging beam. A change in the internal pressure of a channel deforms the elastic channel, which can be detected by measuring speckle patterns of a coherent laser that has passed through the channel and the Scotch tape. We demonstrate that internal pressure can be remotely sensed with the resolution below 0.1 kPa within a pressure range of 3 kPa after calibration. With its high sensitivity, reproducibility, and easy applicability, the present method will find direct and diverse applications.

    The goal of this research is to provide durable and long-term water management solutions using exterior insulating sheathing as part of the water management system. It is possible to tape or seal the joints in insulating sheathing to create a drainage plane and even an air control layer. There exists the material durability component of the tape as well as the system durability component being the taped insulating sheathing as the drainage plane. This measure guideline provides best practice and product recommendations from the interviewed contractors and homebuilders who collectively have a vast amount of experience. Three significant issues were discussed with the group, which are required to make taped insulating sheathing a simple, long-term, and durable drainage plane: horizontal joints should be limited or eliminated wherever possible; where a horizontal joint exists use superior materials; and frequent installation inspection and regular trade training are required to maintain proper installation.

    The phase assemblage and particle sizes of precursor powders have been optimized in a sequence for fabricating Ag/BSCCO-2223 composite tapes. Firstly, an optimal calcination temperature was determined based on the experimental results. Then, the precursors calcined at the optimal temperature were ball-milled for different dwell times to obtain varied particle sizes. The effects of both the phase assemblages and particle sizes of the precursor powder on the phase formation, microstructure and transport J{sub c} of Bi-2223/Ag tapes have been investigated. The results show that the precursor phase assemblage has a large impact on the reaction routes, microstructure, and J{sub c} property. Meanwhile, a fine powder is beneficial for the grain growth, alignment, and J{sub c} enhancement in fully reacted tapes. The best J{sub c} was achieved in the tape made from the powder after optimizing the phase assemblage and particle size.

    JSDTImport is a computer program for translating native Shuttle Data Tape (SDT) files from American Standard Code for Information Interchange (ASCII) format into databases in other formats. JSDTImport solves the problem of organizing the SDT content, affording flexibility to enable users to choose how to store the information in a database to better support client and server applications. JSDTImport can be dynamically configured by use of a simple Extensible Markup Language (XML) file. JSDTImport uses this XML file to define how each record and field will be parsed, its layout and definition, and how the resulting database will be structured. JSDTImport also includes a client application programming interface (API) layer that provides abstraction for the data-querying process. The API enables a user to specify the search criteria to apply in gathering all the data relevant to a query. The API can be used to organize the SDT content and translate into a native XML database. The XML format is structured into efficient sections, enabling excellent query performance by use of the XPath query language. Optionally, the content can be translated into a Structured Query Language (SQL) database for fast, reliable SQL queries on standard database server computers.

    Jones, D. H.; Coates, G. D.; Kirby, R. H.

    1983-01-01

    A study was designed to evaluate the effectiveness of a video tape detailing the various aspects of instrument scanning by experienced pilots on performance by pilots and copilots undergoing flight training in a Boeing 737 flight simulator. The performance ratings by instructor pilots (IP's) and self-reported instrument scan behavior by trainees were compared with those of a control group. The results indicated that the training tape had little or no effect on performance by trainees in the experimental group. Feedback from the IP's and trainees suggested that a feedback strategy providing each trainee's individual instrument scan behavior might be more beneficial in flight training than the general instructional strategy of the oculometer training tape. Flight training personnel and trainees' reports of performance decrements on or around the third day of flight simulator training were investigated. The IP's performance ratings of 27 pilot and copilot trainees failed to reveal a systematic performance decrement; however, feedback from the trainees revealed that their own attribution of performance decrements was associated with the order in which their training occurred within a session. Further research was suggested.

    In cases of firearm related fatalities a systematic investigation at the scene of death is indispensable to differentiate between self-inflicted and homicidal gunshot injuries. A common method to preserve gunshot residues (GSR) is their collection using adhesive tapes. However, the biological material gathered at the same time by the tapes would be of special interest if backspatter, ejected from the entrance wound against the direction of fire, could be detected. In the present study we examined the success rate of co-analysis of RNA and DNA recovered from biological traces sampled with adhesive tapes. The material originated from eight cases of fatal gunshots, taken from the hands of suspects or victims, examined 5 to 19 years ago for GSR. For all types of adhesive tapes tested, quantity and quality of the co-extracted nucleic acids was insufficient for successful DNA profiling, but was sufficient for the detection of blood-specific micro RNA (miRNA). In summary, sampling trace evidence from the hands of persons involved in fatal gunshots with adhesive tapes has a long-term detrimental effect on biological traces.

    Chronic ankle instability presents a high incidence and prevalence in basketbal players. It's important to develop strategies to reduce the functional and mechanical limitations resulting from this condition. To compare the effect of Mulligan ́s fibular repositioning taping with a placebo taping immediatly after application and after a running test (Yo-Yo IRT). 16 adult basketball players (10 male, 6 female) with chronic ankle instability and mean age 21.50 ± 2.76 years old. Assessment of static postural control (15 seconds of unipedal stance test with eyes closed in a force platform), functional performance (figure 8 hop test and lateral hop test) and neuromuscular control (peroneus longus latency time in sudden inversion) in two conditions: Mulligan and Placebo. No significant effect was found for the intervantion factor in both hop tests (p>0.170), but there was a significant effect for the time factor (ptaping and Placebo taping in postural control and functional performance in basketball players with chronic ankle instability. However, Mulligan's taping appears to reduce peroneus longus latency time after a running when compared with a placebo taping.

    The main purpose of this project is to implement a Digital Image and Communications (DICOM) compliant online tape library system over the Internet. Once finished, the system will be used to store medical exams generated from U.S. ARMY Mobile ARMY Surgical Hospital (MASH) in Tuzla, Bosnia. A modified UC Davis implementation of DICOM storage class is used for this project. DICOM storage class user and provider are implemented as the system's interface to the Internet. The DICOM software provides flexible configuration options such as types of modalities and trusted remote DICOM hosts. Metadata is extracted from each exam and indexed in a relational database for query and retrieve purposes. The medical images are stored inside the Wolfcreek-9360 tape library system from StorageTek Corporation. The tape library system has nearline access to more than 1000 tapes. Each tape has a capacity of 800 megabytes making the total nearline tape access of around 1 terabyte. The tape library uses the Application Storage Manager (ASM) which provides cost-effective file management, storage, archival, and retrieval services. ASM automatically and transparently copies files from expensive magnetic disk to less expensive nearline tape library, and restores the files back when they are needed. The ASM also provides a crash recovery tool, which enable an entire file system restore in a short time. A graphical user interface (GUI) function is used to view the contents of the storage systems. This GUI also allows user to retrieve the stored exams and send the exams to anywhere on the Internet using DICOM protocols. With the integration of different components of the system, we have implemented a high capacity online tape library storage system that is flexible and easy to use. Using tape as an alternative storage media as opposed to the magnetic disk has the great potential of cost savings in terms of dollars per megabyte of storage. As this system matures, the Hospital Information Systems

    Chronic ankle instability is characterized by repetitive lateral ankle sprains. Prophylactic ankle taping is a common intervention used to reduce the risk of ankle sprains. However, little research has been conducted to evaluate the effect ankle taping has on gait kinematics. To investigate the effect of taping on ankle and knee kinematics during walking and jogging in participants with chronic ankle instability. Controlled laboratory study. Motion analysis laboratory. A total of 15 individuals (8 men, 7 women; age = 26.9 ± 6.8 years, height = 171.7 ± 6.3 cm, mass = 73.5 ± 10.7 kg) with self-reported chronic ankle instability volunteered. They had an average of 5.3 ± 3.1 incidences of ankle sprain. Participants walked and jogged in shoes on a treadmill while untaped and taped. The tape technique was a traditional preventive taping procedure. Conditions were randomized. Frontal-plane and sagittal-plane ankle and sagittal-plane knee kinematics were recorded throughout the entire gait cycle. Group means and 90% confidence intervals were calculated, plotted, and inspected for percentages of the gait cycle in which the confidence intervals did not overlap. During walking, participants were less plantar flexed from 64% to 69% of the gait cycle (mean difference = 5.73° ± 0.54°) and less inverted from 51% to 61% (mean difference = 4.34° ± 0.65°) and 76% to 81% (mean difference = 5.55° ± 0.54°) of the gait cycle when taped. During jogging, participants were less dorsiflexed from 12% to 21% (mean difference = 4.91° ± 0.18°) and less inverted from 47% to 58% (mean difference = 6.52° ± 0.12°) of the gait cycle when taped. No sagittal-plane knee kinematic differences were found. In those with chronic ankle instability, taping resulted in a more neutral ankle position during walking and jogging in shoes on a treadmill. This change in foot positioning and the mechanical properties of the tape may explain the protective aspect of taping in preventing lateral

    2010-04-01

    Recent studies indicate that playing action video games improves performance on a number of attention-based tasks. However, it remains unclear whether action video game experience primarily affects endogenous or exogenous forms of spatial orienting. To examine this issue, action video game players and non-action video game players performed an attentional capture task. The results show that action video game players responded quicker than non-action video game players, both when a target appeared in isolation and when a salient, task-irrelevant distractor was present in the display. Action video game players additionally showed a smaller capture effect than did non-action video game players. When coupled with the findings of previous studies, the collective evidence indicates that extensive experience with action video games may enhance players' top-down attentional control, which, in turn, can modulate the negative effects of bottom-up attentional capture.

  18. Robust Shot Boundary Detection from Video Using Dynamic Texture

    2014-03-01

    Full Text Available Video boundary detection belongs to a basis subject in computer vision. It is more important to video analysis and video understanding. The existing video boundary detection methods always are effective to certain types of video data. These methods have relatively low generalization ability. We present a novel shot boundary detection algorithm based on video dynamic texture. Firstly, the two adjacent frames are read from a given video. We normalize the two frames to get the same size frame. Secondly, we divide these frames into some sub-domain on the same standard. The following thing is to calculate the average gradient direction of sub-domain and form dynamic texture. Finally, the dynamic texture of adjacent frames is compared. We have done some experiments in different types of video data. These experimental results show that our method has high generalization ability. To different type of videos, our algorithm can achieve higher average precision and average recall relative to some algorithms.

  12. Flow structure and heat transfer in a square duct fitted with dual/quadruple twisted-tapes: Influence of tape configuration

    Energy Technology Data Exchange (ETDEWEB)

    2015-08-15

    Numerical predictions reported of thermohydraulic characteristics of square ducts equipped with dual and quadruple twisted tapes (DTs and QTs) with different configurations. The studied cases include (1) dual co-tapes (Co-DTs), (2) dual counter-tapes (C-DTs), (3) diagonal dual counter-tapes (C-DDTs), (4) diagonal dual co-tapes (Co-DDTs), (5) quadruple co-tapes (Co-QTs), (6) quadruple counter tapes (CC-QTs) and (7) quadruple counter-tapes (PC-QTs). The results of these cases are compared with those of a smooth duct (a duct without tape insert) and also the one with a single tape (ST). The prediction involves using the RNG k-ε turbulent model under constant wall heat flux condition in the turbulent flow regime for the Reynolds number ranging from 6000 to 14000. The prediction indicates that thermohydraulic characteristics in ducts with twisted tape are strongly dependent on number and configuration of tapes. However, the influence of tape number is more significant than that of tape configuration. Heat transfer and friction increase as tape number increases. QTs offer superior heat transfer to DTs but their thermal performance factors are lower. For the tape inserts determined, DTs with diagonal configuration (Co-DDTs and C-DDTs) is the best design as the tapes offer the best thermal performance. The highest thermal performance factors given by Co-DTs, Co-DDTs, C-DTs, C-DDTs, Co-QTs, PC-QTs and CC-QTs, are around 1.21, 1.35, 1.25, 1.38, 1.08, 1.18, and 1.22, respectively.

    To determine whether therapeutic taping, which includes elastic (Kinesio tape) and non-elastic (Leukotape) taping, is superior to control taping in improving pain and functions for patients with knee arthritis. To understand whether both elastic and non-elastic taping are beneficial. We searched the PubMed and Scopus databases from their earliest record to 31 May 2017 for randomized controlled and cross-over studies that used taping to treat knee osteoarthritis. We extracted the mean differences and SD between baseline and posttreatment for selected outcomes measured in the experimental and control groups for subsequent meta-analyses. In total, 11 studies were included in the review. Of which, five Leukotaping and five Kinesio taping studies involving 379 participants were used in the meta-analysis. PEDro scores of the Leukotaping and Kinesio taping studies were 4.2 and 7.8, respectively. Overall, therapeutic taping exhibited significantly greater pain reduction than control taping with a significant weighted mean difference of 12.8 mm on a 0- to 100-mm visual analogue scale. Compared to control taping, Leukotaping produced a significant weighted mean difference of 11.6 mm regarding pain with a large effect size of 0.89 and I(2) = 0%, while Kinesio taping produced a non-significant weighted mean difference of 12.1 mm and I(2) = 93%. Leukotaping also exhibited a large and significant standard mean difference of 0.82, while Kinesio taping exhibited a non-significant standard mean difference of 1.34 regarding climbing stairs and stepping. Therapeutic taping seemed to be superior to control taping in pain control for knee osteoarthritis. Non-elastic taping, but not elastic taping, provides benefits in pain reduction and functional performance.

    The video coding and distribution approach presented in this paper has two key characteristics that make it ideal for integration of video communication services over common broadband digital networks. The modular multi-resolution nature of the coding scheme provides the necessary flexibility to accommodate future advances in video technology as well as robust distribution over various network environments. This paper will present an efficient and scalable coding scheme for video communications. The scheme is capable of encoding and decoding video signals in a hierarchical, multilayer fashion to provide video at differing quality grades. Subsequently, the utilization of this approach to enable efficient bandwidth sharing and robust distribution of video signals in multipoint communications is presented. Coding and distribution architectures are discussed which include multi-party communications in a multi-window fashion within ATM environments. Furthermore, under the limited capabilities typical of wideband/broadband access networks, this architecture accommodates important video-based service applications such as Interactive Distance Learning.

    [Purpose] The purpose of this research was to evaluate the change in muscle function induced by a Kinesio Tape application with no or moderate tension, to the dominant and non-dominant arms. [Subjects and Methods] This research was a quantitative study, in which 75 women participated. The subjects, aged 18-30 years, were divided into 3 groups, Kinesio, Kinesio without Tension, and Control, and they were assessed before the taping intervention and after 30 minutes, 24 hours, and 48 hours of taping. [Results] The Kinesio group subjects demonstrated an increase in handgrip strength after 30 minutes, 24 hours, and 48 hours of tape application compared to control. A statistically significant increase in strength was observed in the Kinesio group comparison to the Control after 24 hours and 48 hours for the right hand, and after 48 hours for the left hand. Improvement in the Kinesio group compared to the Kinesio without Tension was observed only after 24 hours of taping application, and only in the right hand. [Conclusion] The Kinesio Taping method augmented the handgrip strength of healthy women, and the increase in grip strength was maintained for 48 hours after its application; the dominant hand demonstrated the greatest strength values.

    Full Text Available Background : Kinesio Taping (KT is widely used, however the effects of KT on muscle activation and force are contradictory. Objective : To evaluate the effects of KT on knee extension force in soccer players. Method: This is a clinical trial study design. Thirty-four subjects performed two maximal isometric voluntary contractions of the lower limbs pre, immediately post, and 24 hours after tape application on the lower limbs. Both lower limbs were taped, using K-Tape and 3M Micropore tape randomly on the right and left thighs of the participants. Isometric knee extension force was measured for dominant side using a strain gauge. The following variables were assessed: peak force, time to peak force, rate of force development until peak force, time to peak rate of force development, and 200 ms pulse. Results : There were no statistically significant differences in the variables assessed between KT and Micropore conditions (F=0.645, p=0.666 or among testing sessions (pre, post, and 24h after (F=0.528, p=0.868, and there was no statistical significance (F=0.271, p=0.986 for interaction between tape conditions and testing session. Conclusion: KT did not affect the force-related measures assessed immediately and 24 hours after the KT application compared with Micropore application, during maximal isometric voluntary knee extension.

    HSM systems such as the CERN’s Advanced STORage manager (CASTOR) [1] are responsible for storing Petabytes of data which is first cached on disk and then persistently stored on tape media. The contents of these tapes are regularly repacked from older, lower-density media to new-generation, higher-density media in order to free up physical space and ensure long term data integrity and availability. With the evolution of price decay and higher capacity of disk (and flash memory) based storage, our future vision for tape usage is to move away from serving on demand, random, per-file access to non-disk cached files, and to move towards loosely coupled, efficient bulk data transfers where large-volume data sets are stored and retrieved in aggregations, fully exploiting the stream-based nature of tape media. Mechanisms for grouped migration policies and priorities have been implemented, and an innovative tape format optimized for data aggregations is being developed. This new tape format will also allow for incre...

    Little is known about the effects of Kinesio taping and therapeutic exercise on correcting forward head posture. To compare Kinesio taping versus therapeutic exercise for forward head posture on static posture, dynamic mobility and functional outcomes. Sixty subjects (31 women, 29 men) with forward head postures participated in this study. They were randomly assigned to either one of the three groups: (1) exercise group (n = 20), (2) taping group (n = 20), and (3) control groups (n = 20). The horizontal forward displacement (HFD) between ear lobe and acromion process, upper cervical and lower cervical angle (UCA, LCA), active range of motion (AROM) of cervical spine, and neck disability index (NDI) were measured before and after a 5-week intervention, and a 2-week follow-up. Data were analyzed by means of a mixed design repeated-measures ANOVA. Both taping and exercise groups showed significant improvements in HFD compared with the control group at post-treatment and follow-up. Compared with the control group, the exercise group exhibited significant improvements in the LCA and the side bending AROM at post-treatment. Both Kinesio taping and therapeutic exercise improve forward head posture after intervention and a 2-week follow-up. The effectiveness of therapeutic exercise is better than taping.

    Video provides a rich source of data for geophysical analysis, often supplying detailed information about the environment when other instruments may not. This is especially true of deep-sea environments, where direct visual observations cannot be made. As computer vision techniques improve and volumes of video data increase, automated video analysis is emerging as a practical alternative to labor-intensive manual analysis. Automated techniques can be much more sensitive to video quality than their manual counterparts, so performing quality assessment before doing full analysis is critical to producing valid results.Ocean Networks Canada (ONC), an initiative of the University of Victoria, operates cabled ocean observatories that supply continuous power and Internet connectivity to a broad suite of subsea instruments from the coast to the deep sea, including video and still cameras. This network of ocean observatories has produced almost 20,000 hours of video (about 38 hours are recorded each day) and an additional 8,000 hours of logs from remotely operated vehicle (ROV) dives. We begin by surveying some ways in which deep-sea video poses challenges for automated analysis, including: 1. Non-uniform lighting: Single, directional, light sources produce uneven luminance distributions and shadows; remotely operated lighting equipment are also susceptible to technical failures. 2. Particulate noise: Turbidity and marine snow are often present in underwater video; particles in the water column can have sharper focus and higher contrast than the objects of interest due to their proximity to the light source and can also influence the camera's autofocus and auto white-balance routines. 3. Color distortion (low contrast): The rate of absorption of light in water varies by wavelength, and is higher overall than in air, altering apparent colors and lowering the contrast of objects at a distance.We also describe measures under development at ONC for detecting and mitigating

    Hallux valgus, an increased angle of lateral deviation in the big toe, can cause pain and difficulties in balancing and walking. This study aimed to investigate the effects of balance taping using elastic therapeutic tape on moderate hallux valgus. When she walked with shoes, she complained of pain over the medial eminence of the hallux metatarsophalangeal (MTP) joint. Balance taping using kinesiology tape was applied for 3 months (average, 16hours/d) to both big toes of a 26-year-old woman with moderate hallux valgus. On the right side, the hallux valgus angle (HVA) decreased from 21° to 14° and the intermetatarsal angle (IMA) decreased from 15° to 14.5°. On the left side, the HVA decreased from 22° to 11° and the IMA decreased from 15° to 12°. Furthermore, the patient was able to walk long distances in shoes without pain in the medial eminence of the hallux metatarsophalangeal joint. This study suggested that repeated balance taping with kinesiology tape could be used as a complementary treatment method for moderate hallux valgus.

    To verify effects of kinesio taping (KT) in shoulder subacromial impingement syndrome (SIS) when compared to sham taping applied in the same way with KT. Patients were randomized as group 1 (n = 21) KT group and group 2 (n = 20) sham-taping group. Taping was applied every three days, three times during the study period. We assessed all the patients at baseline, at the end of the taping period (12th day), and at one-month post-intervention. We assessed pain on the 100 mm visual analog scale (VAS). Shoulder range of motion (ROM), Constant Scores, and Nottingham Health Profile (NHP) scores were evaluated. Of the 41 participants, 13 were males (32%) and 28 were females (68%). The mean age was 45 ± 15 years (range 20-65 years). We documented a significant decrease in VAS for nocturnal pain, and Constant Score in both groups. The KT group showed additional significant change in NHP pain and physical activity scores. KT and sham taping generated similar results regarding pain and Constant Scores.

    The Broselow Pediatric Emergency Tape (Armstrong Medical Industries, Inc., Lincolnshire, IL) (BT) is a well-established length-based tool for estimation of body weight for children during resuscitation. In view of pandemic childhood obesity, the BT may no longer accurately estimate weight. We therefore studied the BT in children from Ontario in a large recent patient cohort. Actual height and weight were obtained from an urban and a rural setting. Children were prospectively recruited between April 2007 and July 2008 from the emergency department and outpatient clinics at the London Health Science Centre. Rural children from junior kindergarten to grade 4 were also recruited in the spring of 2008 from the Avon Maitland District School Board. Data for preschool children were obtained from three daycare centres and the electronic medical record from the Maitland Valley Medical Centre. The predicted weight from the BT was compared to the actual weight using Spearman rank correlation; agreement and percent error (PE) were also calculated. A total of 6,361 children (46.2% female) were included in the study. The median age was 3.9 years (interquartile range [IQR] 1.56-7.67 years), weight was 17.2 kg (IQR 11.6-25.4 kg), and height was 103.5 cm (IQR 82-124.4 cm). Although the BT weight estimate correlated with the actual weight (r  =  0.95577, p < 0.0001), the BT underestimated the actual weight by 1.62 kg (7.1% ± 16.9% SD, 95% CI -26.0-40.2). The BT had an ≥ 10% PE 43.7% of the time. Although the BT remains an effective method for estimating pediatric weight, it was not accurate and tended to underestimate the weight of Ontario children. Until more accurate measurement tools for emergency departments are developed, physicians should be aware of this discrepancy.

    2014-01-01

    The detailed mechanical design of a novel deployable support structure that positions and tensions a membrane optic for space imagining applications is presented. This is a complex three-dimensional deployment using freely deploying rollable composite tape spring booms that become load bearing structural members at full deployment. The deployment tests successfully demonstrate a new architecture based on rolled and freely deployed composite tape spring members that achieve simultaneous deployment without mechanical synchronization. Proper design of the flexible component mounting interface and constraint systems, which were critical in achieving a functioning unit, are described. These flexible composite components have much potential for advancing the state of the art in deployable structures, but have yet to be widely adopted. This paper demonstrates the feasibility and advantages of implementing flexible composite components, including the design details on how to integrate with required traditional mechanisms.

    Abnormalities of one pelvic floor compartment are usually associated with anomalies in the other compartments. Therapies which specifically address one clinical problem may potentially adversely affect other pelvic floor activities. A new comprehensive holistic scoring system defining global pelvic function is presented. A novel scoring system with a software program is presented expressing faecal, urinary and gynaecological functions as a geometric polygon based on symptom-specific questionnaires [the three axial pelvic evaluation (TAPE) score] where differences in overall geometric area vary from normal. After validation in healthy volunteers, its clinical performance was tested on patients with obstructed defaecation, genital prolapse and urinary/faecal incontinence treated by the stapled transanal rectal resection (STARR) procedure, colpo-hysterectomy and sacral nerve modulation, respectively. The TAPE score was correlated with the Pelvic Floor Impact Questionnaire 7 quality of life score. There was good inter-observer variation and internal consistency between two observers recording the TAPE score in normal volunteers. In the STARR patients, constipation improved but the TAPE score was unchanged because of deterioration in other pelvic floor functions leading to an unchanged overall postoperative recorded quality of life. Conversely, incontinent patients treated with sacral nerve stimulation improved their function showing concomitant improvements in TAPE scores and quality of life indices. Similar correlative improvements were noted in patients undergoing hysterectomy for genital prolapse. The TAPE score defines the impact of symptom-specific treatments on the pelvic floor and may provide an opportunity for comparison of clinical data between units and in clinical trials of specific medical and surgical pelvic floor management.

    2007-12-01

    Gerald Frederick Tape, a distinguished science statesman and administrator, died on November 20, 2005. Jerry, as he was known to all, took on many diverse and important responsibilities throughout his life and dealt with them with quiet authority and grace. This was the hallmark of his life. The Board of Trustees of Associated Universities, Inc., which he served for many years, expressed this in its condolences, writing "Jerry personified integrity, thoroughness and dedication. His sensitivity for the views of others, his sincerity, his personal commitment, his calm approach and his unfailing good humor were all greatly admired and respected." Jerry was born in Ann Arbor, Michigan on May 29, 1915 but grew up in Milan, a nearby country farm community, and in Ypsilanti where his father was Principal of Michigan State Normal College, which later became Eastern Michigan University (EMU). It was there that he first became interested in physics. It was there also that he met and courted Josephine Waffen, who later would become his wife for more than sixty-six years and fill their lives with three loving sons, Walter, James, and Thomas. Upon graduation from EMU, Jerry was awarded a scholarship that took him to the University of Michigan where he earned a Ph.D. in Physics, researching the decay modes of the radioisotopes of iodine. In the Fall of 1939, during the waning days of the Great Depression, he was offered an Instructorship in the Physics Department of Cornell University, a promising start for a fruitful academic career. He brought his bride Jo to Ithaca and joined the cyclotron group under Robert Bacher and Willy Higginbotham while devising a laboratory course in nuclear techniques for graduate students. Bacher and Higginbotham soon left Cornell to join a new wartime laboratory at the Massachusetts Institute of Technology (MIT) and many other colleagues were "drafted" for war work. Bacher persuaded Jerry to join him at the MIT Radiation Laboratory in February

    2016-06-01

    Video games are played by a majority of adolescents, yet little is known about whether and how video games are associated with smoking behavior and attitudes. This systematic review examines research on the relationship between video games and smoking. We searched MEDLINE, psycINFO, and Web of Science through August 20, 2014. Twenty-four studies met inclusion criteria. Studies were synthesized qualitatively in four domains: the prevalence and incidence of smoking imagery in video games (n = 6), video game playing and smoking behavior (n = 11), video game addiction and tobacco addiction (n = 5) and genre-specific game playing and smoking behavior (n = 3). Tobacco content was present in a subset of video games. The literature is inconclusive as to whether exposure to video games as a single construct is associated with smoking behavior. Four of five studies found an association between video game addiction and smoking. For genre-specific game playing, studies suggest that the type of game played affected association with smoking behavior. Research on how playing video games influences adolescents' perceptions of smoking and smoking behaviors is still in its nascence. Further research is needed to understand how adolescents respond to viewing and manipulating tobacco imagery, and whether engaging in game smoking translates into changes in real-world attitudes or behavior. Smoking imagery in video games may contribute to normalizing adolescent smoking. A large body of research has shown that smoking imagery in a variety of media types contributes to adolescent smoking uptake and the normalization of smoking behavior, and almost 90% of adolescents play video games, yet there has never been a published systematic review of the literature on this important topic. This is the first systematic review to examine the research on tobacco and video games.We found that tobacco imagery is indeed present in video games, the relationship between video game playing and smoking

    Joint position sense (JPS) is a key neuromuscular factor for developing and maintaining control of muscles around a joint. It is important when performing specialized tasks, especially at the shoulder. No researchers have studied how Kinesio Tape (KT) application affects JPS. To investigate the effects of KT application and no tape on shoulder JPS at increasing shoulder elevations in athletes. Cross-sectional study. University laboratory. A total of 27 healthy athletes who did not participate in overhead sports (age = 20.44 ± 1.05 years, height = 175.02 ± 11.67 cm, mass = 70.74 ± 9.65 kg) with no previous pathologic shoulder conditions volunteered for the study. All participants were from 1 university. Shoulder JPS was assessed at increasing elevations with and without KT application. Participants attempted to actively replicate 3 target positions with and without the KT and without visual guidance. We examined absolute and variable repositioning errors at increasing shoulder-elevation levels with and without KT application. Data revealed an interaction between tape and position for absolute error (F2,52 = 4.07, P = .02); simple effects revealed an increase in error, with KT demonstrating a 2.65° increase in error at 90° of elevation compared with no tape (t26 = 2.65, P = .01). The effect size was medium (ω(2) = .135). Variable error showed no interaction of tape and position (F2,52 = .709, P = .50). Further analysis of simple effects was not needed. However, we still calculated the effect size and observed small effect sizes for tape (ω(2) = .002), position (ω(2) = .072), and tape by position (ω(2) = .027). At 90° of elevation, shoulder JPS was impaired by the application of KT.

    This report describes the results of accelerated aging experiments (weathering) conducted on prototype tamper tapes bonded to a variety of surface materials. The prototype tamper tapes were based on the patented Confirm{reg_sign} tamper-indicating technology developed and produced by 3M Company. Tamper tapes bonded to surfaces using pressure sensitive adhesive (PSA) and four rapid-set adhesives were evaluated. The configurations of the PSA-bonded tamper tapes were 1.27-cm-wide Confirm{reg_sign} 1700 windows with vinyl underlay and 2.54-cm-wide Confirm{reg_sign} 1700 windows with vinyl and polyester underlays. The configurations of the rapid-set adhesive-bonded tamper tapes were 2.54-cm-wide Confirm{reg_sign} (1700, 1500 with and without primer, and 1300) windows with vinyl underlay. Surfaces used for bonding included aluminum, steel, stainless steel, Kevlar{reg_sign}, brass, copper, fiberglass/resin with and without gel coat, polyurethane-painted steel, acrylonitrile:butadiene:styrene plastic, polyester fiberglass board, Lexan polycarbonate, and cedar wood. Weathering conditions included a QUV cabinet (ultraviolet light at 60{degrees}C, condensing humidity at 40{degrees}C), a thermal cycling cabinet (-18{degrees}C to 46{degrees}C), a Weather-O-Meter (Xenon lamp), and exposure outdoors in Daytona Beach, Florida. Environmental aging exposures lasted from 7 weeks to 5 months. After exposure, the tamper tapes were visually examined and tested for transfer resistance. Tamper tapes were also exposed to a variety of chemical liquids (including organic solvents, acids, bases, and oxidizing liquids) to determine chemical resistance and to sand to determine abrasion resistance.

    Diminished Reality is a new fascinating technology that removes real-world content from live video streams. This sensational live video manipulation actually removes real objects and generates a coherent video stream in real-time. Viewers cannot detect modified content. Existing approaches are restricted to moving objects and static or almost static cameras and do not allow real-time manipulation of video content. Jan Herling presents a new and innovative approach for real-time object removal with arbitrary camera movements.

    Paper discusses strengthening efficiency of relatively new kind of SRP composite based on high strength steel wires. They are made of ultra-high strength steel primarily used in cords of car tires. Through advanced treatment, the mechanical properties of SRP steel are similar to other high carbon cold drawn steels used in construction industry. Strength significantly exceed 2000 MPa, there is no perfect plasticity at yield stress level. Almost linear stress-strain relationship makes SRP steel mechanical properties similar to carbon fibers. Also flexibility and weight ratio of the composite overlay is slightly worse than CFRP strip. Despite these advantages SRP is not as popular as other composites reinforced with fibers of high strength. This is due to the small number of studies of SRP behavior and applicability. Paper shows selected results of the laboratory test of beams strengthened with use of SRP and CFRP externally bonded overlays. Attention has been focused primarily on the phenomenon of cracking. Comparison include the cracking moment, crack width and spacing, coverage of crack zone. Despite the somewhat lower rigidity of SRP tapes, they have a much better adhesion to concrete, so that the crack width is comparable in almost the whole load range. The paper also includes an assessment of the common methods of checking the condition of cracking in relation to the tested SRP strengthening. The paper presents actual calculation procedures to determine the crack spacing and crack width. The discussed formulas are verified with results of provided laboratory tests.

    We prospectively compared the efficacy and safety of tension-free vaginal tape and transobturator vaginal tape inside-out for female stress urinary incontinence. A total of 120 women with stress urinary incontinence were alternately assigned to the tension-free vaginal tape group (60) or the transobturator vaginal tape inside-out group (60). Preoperative evaluation included urodynamic study and a Korean version of the incontinence quality of life questionnaire. One year after operation the surgical result, patient satisfaction, incontinence quality of life questionnaire, long-term complications and uroflowmetry were evaluated in the 2 groups. Patient characteristics were comparable in the 2 groups. Mean +/- SD operative time was significantly shorter in the transobturator vaginal tape inside-out vs the tension-free vaginal tape group (11 +/- 1.4 vs 15 +/- 1.8 minutes). In the transobturator vaginal tape inside-out and the tension-free vaginal tape groups the rates of cure (86.8% and 86.8%), improvement (6.6% and 8.2%) and failure (6.6% and 5.0%, respectively) were similar. Incontinence quality of life questionnaire parameters 1 year after surgery were improved significantly in each group and there was no difference between the 2 groups (p 0.05, respectively). There was no long-term complication in either group. Preoperative urge incontinence resolved in 80% of the tension-free vaginal tape group and in 100% of the transobturator vaginal tape inside-out group. De novo urgency developed in 4 patients (6.6%) in the transobturator vaginal tape inside-out group. The tension-free vaginal tape and transobturator vaginal tape inside-out procedures were minimally invasive and similar in operation related morbidity. Transobturator vaginal tape inside-out appeared to be as effective and safe as tension-free vaginal tape for the surgical treatment of stress urinary incontinence in women at 1-year followup.

    Kinesiology tape (KinTape) is a therapeutic tape without much understanding of its mechanism. KinTape claims to increase cutaneous stimulation, which facilitates motor unit firing, and consequently improves functional performance; however these, benefits could be due to placebo effects. This study investigated the true effects of KinTape by a deceptive, randomized, and controlled trial. Thirty healthy participants performed isokinetic testing of three taping conditions: true facilitative KinTape, sham KinTape, and no KinTape. The participants were blindfolded during the evaluation. Under the pretense of applying adhesive muscle sensors, KinTape was applied to their quadriceps in the first two conditions. Normalized peak torque, normalized total work, and time to peak torque were measured at two angular speeds (60°/s and 180°/s) and analyzed with one-way repeated measures ANOVA. Participants were successfully deceived and they were ignorant about KinTape. No significant differences were found between normalized peak torque, normalized total work, and time to peak torque at 60°/s or 180°/s (p = 0.31-0.99) between three taping conditions. The results showed that KinTape did not facilitate muscle performance in generating higher peak torque, yielding a greater total work, or inducing an earlier onset of peak torque. These findings suggest that previously reported muscle facilitatory effects using KinTape may be attributed to placebo effects. Copyright © 2014 Elsevier Ltd. All rights reserved.

    An experiment was designed to determine if Kinesio™ taping the anterior and lateral portion of the ankle would enhance ankle proprioception compared to the untaped ankle. 30 subjects, 15 men, 15 women, ages 18-30 participated in this study. Exclusion criteria: Ankle injury Kinesio™ tape to the anterior/lateral portion of the ankle. Constant error and absolute error were determined from the difference between the target angle and the trial angle produced by the subject. The treatment group (Kinesio™ taped subjects) showed no change in constant and absolute error for ankle RJPS in plantar flexion and 20° of plantar flexion with inversion when compared to the untaped results using the same motions. The application of Kinesio™ tape does not appear to enhance proprioception (in terms of RJPS) in healthy individuals as determined by our measures of RJPS at the ankle in the motions of plantar flexion and 20° of plantar flexion with inversion.

    Randomly restoring files from tapes degrades the read performance primarily due to frequent tape mounts. The high latency and time-consuming tape mount and dismount is a major issue when accessing massive amounts of data from tape storage. BNL’s mass storage system currently holds more than 80 PB of data on tapes, managed by HPSS. To restore files from HPSS, we make use of a scheduler software, called ERADAT. This scheduler system was originally based on code from Oak Ridge National Lab, developed in the early 2000s. After some major modifications and enhancements, ERADAT now provides advanced HPSS resource management, priority queuing, resource sharing, web-browser visibility of real-time staging activities and advanced real-time statistics and graphs. ERADAT is also integrated with ACSLS and HPSS for near real-time mount statistics and resource control in HPSS. ERADAT is also the interface between HPSS and other applications such as the locally developed Data Carousel, providing fair resource-sharing policies and related capabilities. ERADAT has demonstrated great performance at BNL.

  19. Transparent layered YAG ceramics with structured Yb doping produced via tape casting

    The flexibility of the ceramic production process, in particular in terms of shaping and spatial control of distribution of active ions, is one of the strong points in favor of transparent ceramics. In high power lasers in particular, where thermal management is a critical issue, the finely controlled design of spatial distribution of the doping ions within the laser gain media can reduce undesired thermally induced effects and large temperature gradients, and thus enhance the efficiency and laser beam quality especially under increased thermal load. In the present work transparent structured YAG ceramics with Yb doping were produced by tape casting followed by thermal compression of assembled tapes and sintered under high vacuum. The thermal compression of variously doped tape cast layers is a very promising method because it allows a high precision and good control over dopant distribution in the sintered material. After sintering, the distribution of Yb across the layers was characterized by SEM-EDX and the thickness of Yb diffusion zones between the layers with different Yb content was measured. Optical homogeneity was assessed by means of optical transmittance mapping of the samples and by 2D scanning of laser output. The effect of structured dopant distribution on laser performance was measured in quasi-CW and CW regime with different duty factors. Slope efficiency values higher than 50% were measured both in quasi-CW and in CW lasing conditions. The results are in good agreement with previously calculated predictions, confirming the beneficial effect of structured doping on laser performances and enlightening the impact of the residual scattering losses. Compared to other processing methods, such as the pressing of granulated powders, tape casting followed by thermal compression leads to straight and narrow interfaces between layers with different composition and allows to build structures composed of extremely thin layers with defined dopant content.

    Highlights: • Due to manufacturing deviations, the cooling channels are made by double side drilling. • Twisted tapes with two different thicknesses are necessary for a better cooling performance. • The manufacturing of cooling channels and twisted tapes was demonstrated to be feasible. • The water critical heat flux safety margin is higher than 1.5 for the total channel length. • Geometry optimization shown better cooling performance and higher CHF safety margins. - Abstract: The ITER HNB residual ion dump is exposed to a heat load about 17 MW on the dump panels with a peak power density of 7 MW/m{sup 2}. Water flows through cooling channels, 2 m long and 14 mm diameter, realized by double side deep drilling. Unavoidable manufacturing deviations could generate a discontinuity at the channel length center. It is necessary to verify the influence of issues such as cavitation, fluid stagnation, low boiling margins, among others, in the cooling performance. Assuming worst case conditions, analytical and CFD methods showed a subcooled boiling operation with high safety margins to the water critical heat flux. Additionally, by analysing several thermo-hydraulic parameters, the twisted tape cross sections were optimized. Per cooling channel, two twisted tapes are inserted from the sides of the panels, thus, a study of a separation gap between them at the channel length center presented an optimal distance. This paper demonstrates that common machining techniques and drilling tolerances allow the manufacturing of panels able to withstand safely the required beam operation heat loads, even under worst case operation scenarios.
