    Full Text Available Introduction. Articulation is the result of speech organs and it means clean, clear and distinct pronunciation of voices in words. Material and Methods. A prospective study included 24 children between 5 and 15 years of age, of both sexes. All children were monolingual, Serbian being their native language. The quality of articulation was tested with Triage articulation test. Results. Neither omission nor distortion of plosives was observed in any of them, whereas substitution of plosives occurred in 12% of patients. Omission of affricates was not observed in any of the subjects, but substitution and distortion occurred in 29%, and 76% of subjects, respectively. Omission of fricatives was found in 29% subjects, substitution in 52%, and distortion in 82% of subjects. Omission and distortion of nasals was not recorded in any of the subjects, and substitution occurred in 6% of children. Omission of laterals was observed in 6%, substitution in 46% and distortion in 52% of subjects with articulation disorders. Discussion and Conclusion. Articulation disorders were observed not only in children diagnosed with dyslalia but in those with dysphasia and stuttering as well. Children with speech disorders articulate vowels best, then nasals and plosives. Articulation of fricatives and laterals was found to be most severely deviated, including all three disorders, i.e. substitution, omission and distortion. Spasms of speech muscles and vegetative reactions were also observed in this study, but only in children with stuttering.

    Full Text Available Speech and language development is a good indicator of child’s cognitive development. The risk factors influencing development and functioning of prematurely born children are multiple. In addition to articulation disorder, there are motoric, conginitive and social aspects of delayed development. Premature babies are born before they physically ready to leave the womb. However, most babies born after about 26 weeks of gestational age have chances for survival, but they are at a greater risk of medical complications, since the earlier children are born, the less developed their organs are. Aim: To demonstrate basic parameters, establish differences, determine characteristics of disorder of sound articulation in fullterm and preterm children. Methodology: Research was conducted at the Clinics of Child’s Habilitation and Rehabilitation in Novi Sad. The prospective research study was carried out comprising 61 children with mean age of 4 years. The study inclusion criteria were gestational age and birth weight. Regarding these parameters, the children without major neurlologic or system disabilities were included, and they were Serbian speaking. The sample comprised 31 children with GS≥38 weeks and body weight of ≥3000 g, while the preterm group comprised 30 children with GS≤32 weeks and body weight of ≤1500 g. Results of the study indicate to a difference between fullterm children and preterm children with regard to articulation disorders, of which the statistically significant was a sound distortion. The overall sample showed that the substitution with distortion was most frequent disorder, while the interdental sigmatism was the most represented one. Conclusion: The obtained results lead to conclusion that preterm children, being a high-risk group, need to be followed up by age two, and provided timely proffesional help at pre-school age, since numerous adverse factors affect their overall development.

The most common reason for this misdiagnosis is that speech-language pathologists (SLPs are unfamiliar with AAE acquisition and its phonological features. The second is that SLPs administer norm-referenced standardized tests that are culturally biased, which unfairly contributes to these errors. Finally, SLPs often do not realize that AAE speaking children are, in a way, learning a second dialect ¾ Standard American English ¾ in school. Each of these practices delivers inaccurate information about the child, placing the SLPs and their clients at a disadvantage. I will provide recommendations and suggestions for SLPs. My argument is that changes can, and should, be made.

Some children with functional articulation disorders may also have sensory integration dysfunction (SID. We hypothesized that speech therapy would be less efficacious in children with SID than in those without SID. Hence, the purpose of this study was to compare the efficacy of speech therapy in two groups of children with functional articulation disorders: those without and those with SID.Method: A total of 30 young children with functional articulation disorders were divided into two groups, the no-SID group (15 children and the SID group (15 children. The number of pronunciation mistakes was evaluated before and after speech therapy.Results: There were no statistically significant differences in age, sex, sibling order, education of parents, and pretest number of mistakes in pronunciation between the two groups (P > 0.05. The mean and standard deviation in the pre- and posttest number of mistakes in pronunciation were 10.5 ± 3.2 and 3.3 ± 3.3 in the no-SID group, and 10.1 ± 2.9 and 6.9 ± 3.5 in the SID group, respectively.

    Full Text Available Sound expression is the first impression of speech and language. Whatever its origin, false pronunciation is the first sign. In the early school years of developmental speech – if a language disorder appears, it is often followed by the disruption of the phonological – articulation segment.This research aims to establish and compare frequency, type, and every articulate and acoustic characteristics of the disordered sound in both children with Dyslalia, as well as those with SLI.This micro investigation was done using 71 examinees ages 6 to 8. Thirty-five examinees were with Dyslalia and 36 had SLI. Their achievements are underlined using comparative analysis, tested with two relevant tests.Some of the more important conclusions are:Children with Dyslalia mostly showed distorted sounds, while those with SLI mostly substituted the disordered sound. In Dyslalia, fricatives were most affected, but in the case of SLI, all sound groups were disordered usually. In both tested groups, the type of disorder was due to the misplacement of sound formation. All children having articulation disorders while also having sound discrimination have not only phonetic contrasts, but were also being influenced by the rest of the linguistic aspects.

    Genetic factors are an important cause of functional articulation disorder in children. This article reviews some genes and chromosome regions associated with a genetic susceptibility to functional articulation disorders. The forkhead box P2 (FOXP2) gene on chromosome 7 is introduced in details including its structure, expression and (unction. The relationship between the F0XP2 gene and developmental apraxia of speech is discussed. As a transcription factor, FOXP2 gene regulates the expression of many genes. CNTNAP2 as an important target gene of F0XP1 is a key gene influencing language development. Functional articulation disorder may be developed to dyslexia, therefore some candidate regions and genes related to dyslexia, such as3p12-13, 15q11-21, 6p22 and 1 p34-36, are also introduced. ROBO1 gene in 3pl2.3, ZNF280D gene, TCF12 gene, EKN1 gene in 15q21, and KIAA0319 gene in 6p22 have been candidate genes for the study of functional articulation disorder.%遗传因素是造成功能性构音障碍的重要原因.本文综述了最近发现的与功能性构音障碍相关的一些基因和染色体区域.详细介绍了FOXP2基因的结构、表达和功能,以及FOXP2基因在发育性言语失用中的变异.作为重要的转录调控因子,FOXP2基因可以调控很多基因的表达.其中CNTNAP2基因是FOXP2基因的重要靶基因,是影响语言及言语发育的重要基因.功能性构音障碍可能发展为阅读障碍,阅读障碍的候选基因也成为研究功能性构音障碍的重要候选基因.一些与阅读障碍相关的染色体区域3p12-13、15q11-21、6p22及1P34-36被认为可能与功能性构音障碍相关.位于这部分染色体区域的一些基因如ROBO1基因、ZNF280D基因、TCF12基因、EKN1基因、KIAA0319基因等成为研究功能性构音障碍的候选基因.

  2. The psychoacoustics of musical articulation

    Science.gov (United States)

    Spiegelberg, Scott Charles

    This dissertation develops psychoacoustical definitions of notated articulations, the necessary first step in articulation research. This research can be useful to theorists interested in timbre analysis, the psychology of performance, analysis and performance, the psychology of style differentiation, and performance pedagogy. An explanation of wavelet transforms precedes the development of new techniques for analyzing transient sounds. A history of timbre perception research reveals the inadequacies of current sound segmentation models, resulting in the creation of a new model, the Pitch/Amplitude/Centroid Trajectory (PACT) model of sound segmentation. The new analysis techniques and PACT model are used to analyze recordings of performers playing a melodic fragment in a series of notated articulations. Statistical tests showed that the performers generally agreed on the interpretation of five different articulation groups. A cognitive test of articulation similarity, using musicians and non-musicians as participants, revealed a close correlation between similarity judgments and physical attributes, though additional unknown factors are clearly present. A second psychological test explored the perceptual salience of articulation notation, by asking musically-trained participants to match stimuli to the same notations the performers used. The participants also marked verbal descriptors for each articulation, such as short/long, sharp/dull, loud/soft, harsh/gentle, and normal/extreme. These results were matched against the results of Chapters Five and Six, providing an overall interpretation of the psychoacoustics of articulation.

  3. Articulation Points in Complex Networks

    An articulation point in a network is a node whose removal disconnects the network. Those nodes play key roles in ensuring connectivity of many real-world networks, from infrastructure networks to protein interaction networks and terrorist communication networks. Despite their fundamental importance, a general framework of studying articulation points in complex networks is lacking. Here we develop analytical tools to study key issues pertinent to articulation points, e.g. the expected number of them and the network vulnerability against their removal, in an arbitrary complex network. We find that a greedy articulation point removal process provides us a novel perspective on the organizational principles of complex networks. Moreover, this process is associated with two fundamentally different types of percolation transitions with a rich phase diagram. Our results shed light on the design of more resilient infrastructure networks and the effective destruction of terrorist communication networks.

    The students of the Florida A&M/Florida State University College of Engineering continued their design from 1988 to 1989 on a first generation lunar transportation vehicle for use on the surface of the Moon between the years 2010 and 2020. Attention is focused on specific design details on all components of the Lunar Articulated Remote Transportation System (Lunar ARTS). The Lunar ARTS will be a three-cart, six-wheeled articulated vehicle. Its purpose will be the transportation of astronauts and/or materials for excavation purposes at a short distance from the base (37.5 km). The power system includes fuel cells for both the primary system and the back-up system. The vehicle has the option of being operated in a manned or unmanned mode. The unmanned mode includes stereo imaging with signal processing for navigation. For manned missions the display console is a digital readout displayed on the inside of the astronaut's helmet. A microprocessor is also on board the vehicle. Other components of the vehicle include a double wishbone/flexible hemispherical wheel suspension; chassis; a steering system; motors; seat retraints; heat rejection systems; solar flare protection; dust protection; and meteoroid protection. A one-quarter scale dynamic model has been built to study the dynamic behavior of the vehicle. The dynamic model closely captures the mechanical and electrical details of the total design.

    Full Text Available Introduction. Phonetic and phonological system of the healthy members of one linguistic community is fully formed around 8 years of age. The auditory and articulatory habits are established with age and tend to be more difficult to be upgraded and completed later. Material and Methods. The research was done as a cross-sectional study, conducted at the preschool institution “Radosno detinjstvo” and primary school “Branko Radičević” in Novi Sad. It included 66 children of both genders, aged 6 to 8. The quality of articulation was determined according to the Global Articulation Test by working with each child individually. Results. In each individual vowel, plosive, nasal, lateral and fricative, the quality of articulation was statistically significantly better in the first graders compared to the preschool children (p<0.01. In each affricate, except for the sound /ć/, the quality of articulation was statistically significantly better in the first graders than in the preschool children (p<0.01. The quality of articulation of all speech sounds was statistically significantly better in the first graders than in the preschool children (p<0.01. Discussion and Conclusion. The most common disorder of articulation is distortion, while only substitution and substitution associated with distortion are less common. Omission does not occur in children from 6 to 8 years of age. Girls have slightly better quality of articulation. The articulatory disorders are more common in preschool children than in children who are in the first grade of primary school. The most commonly mispronounced sounds belong to the group of affricates and fricatives.

  13. Magnetic resonance in temporomandibular articulations

    International Nuclear Information System (INIS)

    Dysfunction of temporomandibular joint (TMJ) is extremely common, mainly in women. The indication of imaging study of TMJ is the evaluation of its internal derangements, since disc dislocation is treated by different way than other intrinsic mechanical conditions and of the painful myofacial dysfunction, as well where there is no anatomic lesion. The patients, who do not improve with the clinical approach, should be referred to imaging evaluation, in order to rule out mechanical disorder. When the patient is supposed to be operated upon, imaging of the contralateral TMJ is necessary. The presence of a thick and stiff disc perforated with adhesion to the mandibular condyle will change the surgical management. The plain x-ray film is able to demonstrate the bone outlines and joint space but it is not able to show the soft articular tissues. Arthrography is very reliable to demonstrate perforation. However it is an invasive method and demands skilled radiographer radiologist. MRI has shown to be reliable method and it is becoming to be progressively used in routine investigation of TMJ. Nevertheless, MRI still has some limitations concerning to disc perforation. (author). 16 refs, 9 figs

    Conclusions: The word lists in Hindi will be a tool for the Parents, Teachers and Speech Language Therapists to work on different speech sounds for the hearing impaired children with articulation errors. The word lists will also help to improve articulation skills of other children with developmental disorders. However, more number of words lists needs to develop and familiarization need to be done before uses of the developed word lists. [Int J Res Med Sci 2014; 2(4.000: 1580-1585

    2007-04-01

    The existence of equilibrium solutions for a lubricated system consisting of an articulated body sliding over a flat plate is considered. Though this configuration is very common (it corresponds to the popular tilting-pad thrust bearings), the existence problem has only been addressed in extremely simplified cases, such as planar sliders of infinite width. Our results show the existence of at least one equilibrium for a quite general class of (nonplanar) slider shapes. We also extend previous results concerning planar sliders.

    2007-05-01

    Full Text Available We present and describe the development of a framework for assessing or categorizing instructional practices and related conceptions in the context of introductory physics instruction. The purpose of the framework is for articulating practices and conceptions of individual instructors or of curricula. It was developed based on the research literature and interviews with physics faculty and contains ideas with widespread acceptance as well as some outside mainstream rhetoric. We provide an example of how this framework can be applied by using it to categorize aspects of three well-known research-based curricula. The results of this categorization highlight areas that are common in research-based curricular designs and other areas that are less embraced but worthy of consideration.

    Full Text Available This paper deals with the landing motion of an articulated legged robot. Humans use a peculiar crouching motion to land safely which can be characterized by body stiffness and damping. A stiffness controller formulation is used to realize this human behavior for the robot. Using this method, the landing motion is achieved with only the desired body stiffness and damping values, without desired COG(Center of Gravity or joint paths. To achieve soft landing, variable body stiffness and damping values were optimized. PBOT, which has four links with flexible joints was used for validation of the landing controller. A body stiffness and damping controller was used as an outer landing control loop and a fast subsystem controller for flexible joints was used as an inner force control loop. Simulations and experimental results about the landing motion are presented to show the performance of the body stiffness and damping controller.

  7. Kinematical Analysis of an Articulated Mechanism

    CERN Document Server

    Fleischfresser, Luciano

    2015-01-01

    The purpose of this work is twofold: to present mathematical expressions for the kinematics of an articulated mechanism and to perform numerical experiments with the implemented Fortran code. The system of rigid parts is made of two slender bars and a disk. A constant 2 rad/s counterclockwise rotation rate is imposed on the disk triggering the planar motion of the longer bar (link) and the rotation of the shorter one (output). Angular relations, velocities and accelerations are analyzed for a 90-degree turn of the disk. The inversion of the linking bar sense of rotation is well captured by the simulation, and the paper and pencil solutions that may lead to wrong conclusions are explained. Equations are derived from first principles and the Fortran code is placed under version control (currently, v.0.8-beta). This computer project is relevant for those in charge of vector dynamics courses and wishing to expose students to project-based learning activities.

    Full Text Available Getting closer to the articulation segment of SLI is important for diagnosis of children in early school age. Phonologic and articulation status of this population is specific, and acknowledging it, will secure adequate rehabilitation.The theory offers wide analysis of physiology of all speech-language aspects of the developmental period, as well as its pathology. The emphasis is put on the articulation segment in children with SLI.The goal of this study was to establish direct relation between speech-language development delay and the process of sound forming in children with SLI, and in the same time comparing it with the normal speech-language development.In this study a group of 35 children with SLI, and a group of 35 children without this problem were included.The examination was performed with four relevant tests: Global articulation test, Test for examining articulation, Articulation test for analytic estimation of phonologic and articulation disorders and Test for understanding speech.For processing data from empiric frequencies for specific categories in both tested groups, c2 test was used. In the same time, establishing correlation level between groups of different characteristics in examinees, quotient of contingency was included. Since the necessary confirmation of results correlation among different test results scored in both groups, Pearson test of correlation was also used. The results showed some important characteristics of phonologic-articulation disorders. Children suffering from SLI have approximately 20 well pronounced sounds. The biggest problem is pronunciation of sounds from fricative and affricate group, medial position of sound in a word, and the most frequent sound disorder is substitution. Detailed analysis resulted with dominant problem with the place of sound production, except in cases of sound mispronunciation of vowels and nasals.When estimating sound quality in word and sentence order, deviation of

  10. Nasal reconstruction with articulated irradiated rib cartilage

    International Nuclear Information System (INIS)

    Nasal structural reconstruction is a formidable task in cases where there is loss of support to both the nasal dorsum and tip. A multitude of surgical approaches and materials have been used for the correction of the saddle-nose deformity with varying degrees of success. Articulated irradiated rib cartilage inserted through an external rhinoplasty approach was used to reconstruct nasal deformities in 18 patients over a 6-year period. Simultaneous use of a midline forehead flap to reconstruct the overlying soft tissue was required in four cases. Follow-up ranged from 1 to 6 years (mean, 2.8 years). Results were rewarding in most cases with marked improvement in nasal support and airway. Revision and/or replacement secondary to trauma or warping of the graft was required in four cases. None of the patients exhibited infection, extrusion, or noticeable resorption. A description of the surgical technique, review of all the cases, and recommendation for continued use of this graft material are discussed

  11. Vocal tract articulation in zebra finches.

    Directory of Open Access Journals (Sweden)

    Verena R Ohms

    Full Text Available BACKGROUND: Birdsong and human vocal communication are both complex behaviours which show striking similarities mainly thought to be present in the area of development and learning. Recent studies, however, suggest that there are also parallels in vocal production mechanisms. While it has been long thought that vocal tract filtering, as it occurs in human speech, only plays a minor role in birdsong there is an increasing number of studies indicating the presence of sound filtering mechanisms in bird vocalizations as well. METHODOLOGY/PRINCIPAL FINDINGS: Correlating high-speed X-ray cinematographic imaging of singing zebra finches (Taeniopygia guttata to song structures we identified beak gape and the expansion of the oropharyngeal-esophageal cavity (OEC as potential articulators. We subsequently manipulated both structures in an experiment in which we played sound through the vocal tract of dead birds. Comparing acoustic input with acoustic output showed that OEC expansion causes an energy shift towards lower frequencies and an amplitude increase whereas a wide beak gape emphasizes frequencies around 5 kilohertz and above. CONCLUSION: These findings confirm that birds can modulate their song by using vocal tract filtering and demonstrate how OEC and beak gape contribute to this modulation.

    2016-05-01

    It is known that articulating different syllables is linked to different grasp actions, e.g. [ti] is linked to precision grip, and [kɑ] to power grip. The aim of the present study was to test whether articulating or hearing these syllables would result in an increased activity in the representation of hand muscles involved in these two actions in a muscle-specific manner. To this end, we used transcranial magnetic stimulation (TMS) to investigate changes in the excitability of the left primary motor cortex (M1) innervating hand muscles while participants articulated or listened to meaningless syllables, listened to a metronome, or observed a fixation cross. The motor-evoked potentials of two hand muscles associated with either a precision or power grip exhibited significantly greater amplitudes during articulation than in passive listening, metronome, and fixation cross conditions. Moreover, these muscles exhibited similar patterns of excitability during articulation regardless of which syllable was articulated. The increased excitability of the left M1 hand area during articulation, but not during perception of the syllables, might be due to the cortico-cortical interaction between the motor representations of oral organs with the hand area.

  5. VARIATIONAL MONTE-CARLO APPROACH FOR ARTICULATED OBJECT TRACKING

    Directory of Open Access Journals (Sweden)

    Kartik Dwivedi

    2013-12-01

    Full Text Available In this paper, we describe a novel variational Monte Carlo approach for modeling and tracking body parts of articulated objects. An articulated object (human target is represented as a dynamic Markov network of the different constituent parts. The proposed approach combines local information of individual body parts and other spatial constraints influenced by neighboring parts. The movement of the relative parts of the articulated body is modeled with local information of displacements from the Markov network and the global information from other neighboring parts. We explore the effect of certain model parameters (including the number of parts tracked; number of Monte-Carlo cycles, etc. on system accuracy and show that ourvariational Monte Carlo approach achieves better efficiency and effectiveness compared to other methods on a number of real-time video datasets containing single targets.

  8. Conjugated Polymer Actuators for Articulating Neural Probes and Electrode Interfaces

    Science.gov (United States)

    Daneshvar, Eugene Dariush

    This thesis investigated the potential use of polypyrrole (PPy) doped with dodecylbenzenesulfonate (DBS) to controllably articulate (bend or guide) flexible neural probes and electrodes. PPy(DBS) actuation performance was characterized in the ionic mixture and temperature found in the brain. Nearly all the ions in aCSF were exchanged into the PPy---the cations Na +, K+, Mg2+, Ca2+, as well as the anion PO43-; Cl- was not present. Nevertheless, deflections in aCSF were comparable to those in NaDBS and they were monotonic with oxidation level: strain increased upon reduction, with no reversal of motion despite the mixture of ionic charges and valences being exchanged. Actuation depended on temperature. Upon warming, the cyclic voltammograms showed additional peaks and an increase of 70% in the consumed charge. Actuation strain was monotonic under these conditions, demonstrating that conducting polymer actuators can indeed be used for neural interface and neural probe applications. In addition, a novel microelectro-mechanical system (MEMS) was developed to measure previously disregarded residual stress in a bilayer actuator. Residual stresses are a major concern for MEMS devices as that they can dramatically influence their yield and functionality. This device introduced a new technique to measure micro-scaled actuation forces that may be useful for characterization of other MEMS actuators. Finally, a functional movable parylene-based neural electrode prototype was developed. Employing PPy(DBS) actuators, electrode projections were successfully controlled to either remain flat or actuate out-of-plane and into a brain phantom during insertion. An electrode projection 800 microm long and 50 microm wide was able to deflect almost 800 microm away from the probe substrate. Applications that do not require insertion into tissue may also benefit from the electrode projections described here. Implantable neural interface devices are a critical component to a broad class of

  15. Active cells for redundant and configurable articulated structures

    International Nuclear Information System (INIS)

    The proposed research effort explores the development of active cells—simple contractile electro-mechanical units that can be used as the material basis for larger articulable structures. Each cell, which might be considered a ‘muscle unit,’ consists of a contractile Nitinol Shape Memory Alloy (SMA) core with conductive terminals. Large numbers of these cells might be combined and externally powered to change phase, contracting to either articulate with a large strain or increase the stiffness of the ensemble, depending on the cell design. Unlike traditional work in modular robotics, the approach presented here focuses on cells that have a simplistic design and function, are inexpensive to fabricate, and are eventually scalable to sub-millimeter sizes, working toward our vision of articulated and robotic structures that can be custom-fabricated from large numbers of general cell units, similar to biological structures. In this paper, we present the design of the active cells and demonstrate their usage with three articulated structures built with them. (paper)

Language testing showed a delay in the development of morphosyntactic abilities. Speech analysis showed that these four children were capable of producing all the sounds of their mother tongue. One type of distortion error, namely dentalization, was found in 2 children. Phonological process analysis revealed the persistence of processes such as final consonant deletion, unstressed syllable deletion and cluster reduction, which are normal in young children but are suppressed with maturation. Also the substitution process of devoicing was observed in these 4 children. It is not clear how the speech and language problems demonstrated in these 4 children are to be explained. It must be taken into consideration that the Goldenhar syndrome has a variable expression. It is possible that the presence of a mandibular defect, hearing impairment, the type and severity of palatal abnormality and decreased linguistic processing skills influence articulation in an individual child. The voices of 2 children were characterized by the presence of slight roughness, corresponding with a higher jitter percentage. How the occurrence of the hoarse voices is to be explained is not quite clear. Laryngoscopic evaluation of the vocal folds showed no organic or functional voice disorder. Regarding resonance, only the child with a cleft palate showed hypernasality and nasal emission. The ENT specialist and the speech-language pathologist must be aware of these communication disorders in order to start preventive and early 'tailor-made' speech and language intervention as soon as possible.

  20. Computed tomography of the sternum and its articulations

    International Nuclear Information System (INIS)

    The chest wall presents diagnostic difficulties for both the clinician and the radiologist. Because of normal variations in anatomy and ossification, analysis of the sternal region can be particularly confusing. We reviewed the normal computed tomographie (CT) appearance of the sternum in 354 patients. Important normal sternal variants included cortical insharpness along the posterior aspect of the manubrium, lateral surfaces of the body, and at the sternal fibrocartilaginous articulations; soft tissue prominence at the junction of the sternum and costochondral cartilage; and bony sclerosis at the transitions from manubrium to body and from body to xiphoid. In seven patients with clinically significant sternal abnormality, key CT features were abnormal soft tissue mass (7/7), destruction or irregularity of the cortical contour (7/7), and abnormal increased attenuation of bone (1/7). CT should be the radiologic study of choice in patients with suspected abnormality of the sternum and its articulations. (orig.)

  1. Design and Construction of Passively Articulated Ornithopter Wings

    Science.gov (United States)

    Mastro, Alexander Timothy

    Birds, bats, and insects are able to fly efficiently and execute impressive in-flight, landing, and takeoff maneuvers with apparent ease through actuation of their highly articulated wings. This contrasts the approach used to enable the flight of comparatively simple man-made rotary and fixed wing aircraft. The complex aerodynamics underlying flapping-based flight pose an everpresent challenge to scientists hoping to reveal the secrets of animal flight. Despite this, interest in engineering aircraft on the bird and insect scale is higher than ever. Herein, I present my attempt to design and construct bioinspired passively articulated ornithopter wings. Two different hinge-based joint design concepts are investigated across several design iterations. The advantages and disadvantages of each implementation are discussed. Finally, the necessary instrumentation to analyze the performance of the wings is designed and fabricated, followed by testing of the wings.

    Exemplar-based models have achieved great success on localizing the parts of semi-rigid objects. However, their efficacy on highly articulated objects such as humans is yet to be explored. Inspired by hierarchical object representation and recent application of Deep Convolutional Neural Networks (DCNNs) on human pose estimation, we propose a novel formulation that incorporates both hierarchical exemplar-based models and DCNNs in the spatial terms. Specifically, we obtain more expressive spati...

  8. Muscle Articulations: Flexible Jaw Joints Made of Soft Tissues.

    Science.gov (United States)

    Uyeno, T A; Clark, A J

    2015-08-01

    This study surveys animals that use soft tissues rather than rigid links to build jaw joints. Hard biting elements are useful; they are used in piercing or shearing during feeding and interactive behaviors and can directly impact survival and reproduction. The best understood biting systems include biting elements that are mounted on rigid jaw links that form a joint capable of transmitting the bite reaction forces. As such, jaws must incorporate joints that resist compression. Many jaw joints are "sliding joints", in which jaw links come into direct contact and the shape of the sliding contact surfaces dictates possible motions. There are, however, organisms that have biting elements on jaws that are made of flexible muscle and connective tissues. If arranged as a muscular hydrostat, in which multiple orientations of the muscle fibers may co-contract to provide turgid skeletal support, the multifunctional joint not only (a) provides the force to move the biting elements, but also (b) creates repositionable pivots and (c) transmits bite reaction forces. Such flexible joints, termed "muscle articulations", may be important to a number of soft-bodied animals. In this survey, we review the function of previously described muscle articulations: the joints found between inarticulate brachiopods' valves, cephalopods' beaks, the hooks of kalyptorhynch flatworms, and errant polychaetes' jaws. We also review the morphology, physiology, and feeding behaviors of the hagfish as a putative muscle articulation in an effort to understand how this jawless craniate is capable of biting with surprising force, seemingly without the benefit of any obvious method of opposing the force of the dental plate that is used to remove portions of food. Initial analysis suggests that a muscle articulation may be a key feature in coordinating head and body movements to provide the leverage needed for strong "bites". PMID:25912361

    Ding, Meng; Fan, Guoliang

    2016-02-01

    In this paper, we propose an articulated and generalized Gaussian kernel correlation (GKC)-based framework for human pose estimation. We first derive a unified GKC representation that generalizes the previous sum of Gaussians (SoG)-based methods for the similarity measure between a template and an observation both of which are represented by various SoG variants. Then, we develop an articulated GKC (AGKC) by integrating a kinematic skeleton in a multivariate SoG template that supports subject-specific shape modeling and articulated pose estimation for both the full body and the hands. We further propose a sequential (body/hand) pose tracking algorithm by incorporating three regularization terms in the AGKC function, including visibility, intersection penalty, and pose continuity. Our tracking algorithm is simple yet effective and computationally efficient. We evaluate our algorithm on two benchmark depth data sets. The experimental results are promising and competitive when compared with the state-of-the-art algorithms. PMID:26672042

  12. Strategies for treating compensatory articulation in patients with cleft palate.

    2014-03-01

    Patients with cleft palate frequently show compensatory articulation (CA). CA requires a prolonged period of speech intervention. Some scaffolding strategies can be useful for correcting placement and manner of articulation in these cases. The purpose of this paper was to study whether the use of specific strategies of speech pathology can be more effective if applied according to the level of severity of CA. Ninety patients with CA were studied in two groups. One group was treated using strategies specific for their level of severity of articulation, whereas in the other group all strategies were used indistinctively. The degree of severity of CA was compared at the end of the speech intervention. After the speech therapy intervention, the group of patients in which the strategies were used selectively, showed a significantly greater decrease in the severity of CA, as compared with the patients in whom all the strategies were used indistinctively. An assessment of the severity of CA can be useful for selecting the strategies, which can be more effective for correcting the compensatory errors. PMID:24711749

    Can mouth movements shape attitudes? When people articulate different consonants (e.g., B or K) they press the tongue and the lips against various spots in the mouth. This allows for construction of words that feature systematic wanderings of consonantal stricture spots either from the front to the rear (inward; e.g., BENOKA) or from the rear to the front (outward; e.g., KENOBA) of the mouth. These wanderings of muscular strictures resemble the oral kinematics during either deglution (swallowing-like, inward movement) or expectoration (spitting-like, outward movement). Thus, we predicted that the articulation of inward and outward words induces motivational states associated with deglutition and expectoration--namely, approach and avoidance--which was tested in 9 experiments (total N = 822). Inward words were preferred over outward words, being labeled as nonsense words (Experiments 1, 4, 5, 6, and 9), company names (Experiment 2), or person names (Experiments 3, 7, and 8), with control words falling in between (Experiment 5). As a social-behavioral consequence, ostensible chat partners were more often chosen to interact with when having inward compared to outward names (Experiment 7). The effect was found in German-speaking (Experiments 1-5) and English-speaking (Experiment 6) samples, and it occurred even under silent reading (all experiments) and for negatively labeled targets (names of villains; Experiment 8). Showing articulation simulations as being the causal undercurrent, this effect was absent in aphasia patients who lacked covert subvocalizations (Experiment 9). PMID:24841094

The downward hanging...... pipe position will lose stability if the mean flow speed exceeds a certain critical value.

    MIMICRI is a signal-processing algorithm that has been shown to blindly infer and invert memoryless nonlinear functions of unobservable bandlimited signals, such as the mapping from the unobservable positions of the speech articulators to observable speech sounds. We review results of using MIMICRI on toy problems and on human speech data. We note that MIMICRI requires that the user specify two parameters: the dimensionality and pass-band of the unobservable signals. We show how to use cross-validation to help estimate the passband. An unexpected consequence of this work is that it helps separate signals with overlapping frequency bands.

    2000-07-01

    An important but oft overlooked aspect of any robotic system is the synergistic benefit of designing the chassis to have high intrinsic mobility which complements rather than limits, its system capabilities. This novel concept continues to be investigated by the Defence Research Establishment Suffield (DRES) with the Articulated Navigation Testbed (ANT) Unmanned Ground Vehicle (UGV). The ANT demonstrates high mobility through the combination of articulated steering and a hybrid locomotion scheme which utilizes individually powered wheels on the edge of rigid legs; legs which are capable of approximately 450 degrees of rotation. The configuration can be minimally configured as a 4x4 and modularly expanded to 6x6, 8x8, and so on. This enhanced mobility configuration permits pose control and novel maneuvers such as stepping, bridging, crawling, etc. Resultant mobility improvements, particularly in unstructured and off-road environments, will reduce the resolution with which the UGV sensor systems must perceive its surroundings and decreases the computational requirements of the UGV's perception systems1 for successful semi-autonomous or autonomous terrain negotiation. This paper reviews critical vehicle developments leading up to the ANT concept, describes the basis for its configuration and speculates on the impact of the intrinsic mobility concept for UGV effectiveness.

    In the domain of telerobotic operations, the primary challenge facing the operator is to understand the state of the robotic platform. One key aspect of understanding the state is to visualize the physical location and configuration of the platform. As there is a wide variety of mobile robots, the requirements for visualizing their configurations vary diversely across different platforms. There can also be diversity in the mechanical mobility, such as wheeled, tracked, or legged mobility over surfaces. Adaptable 3D articulated robot visualization software can accommodate a wide variety of robotic platforms and environments. The visualization has been used for surface, aerial, space, and water robotic vehicle visualization during field testing. It has been used to enable operations of wheeled and legged surface vehicles, and can be readily adapted to facilitate other mechanical mobility solutions. The 3D visualization can render an articulated 3D model of a robotic platform for any environment. Given the model, the software receives real-time telemetry from the avionics system onboard the vehicle and animates the robot visualization to reflect the telemetered physical state. This is used to track the position and attitude in real time to monitor the progress of the vehicle as it traverses its environment. It is also used to monitor the state of any or all articulated elements of the vehicle, such as arms, legs, or control surfaces. The visualization can also render other sorts of telemetered states visually, such as stress or strains that are measured by the avionics. Such data can be used to color or annotate the virtual vehicle to indicate nominal or off-nominal states during operation. The visualization is also able to render the simulated environment where the vehicle is operating. For surface and aerial vehicles, it can render the terrain under the vehicle as the avionics sends it location information (GPS, odometry, or star tracking), and locate the vehicle

    This is the third article in a three-part series on the history of denture occlusal grinders. The first article reviewed the earliest attempts to "grind in" denture occlusion by hand manipulating simple articulators with special features to those more complex devices powered by hand cranks. The second article explored devices that were motor driven, either those with cast holders to grind the occlusion of processed dentures or those designed to utilize an articulator's condylar or incisal controls for that purpose. This article examines those articulators that have a rotary occlusal grinder as an essential feature. Additionally, this article reviews those grinding devices produced as attachments for popular contemporary articulators. PMID:25754238

  2. A maximum likelihood approach to estimating articulator positions from speech acoustics

    Energy Technology Data Exchange (ETDEWEB)

    Hogden, J.

    1996-09-23

    This proposal presents an algorithm called maximum likelihood continuity mapping (MALCOM) which recovers the positions of the tongue, jaw, lips, and other speech articulators from measurements of the sound-pressure waveform of speech. MALCOM differs from other techniques for recovering articulator positions from speech in three critical respects: it does not require training on measured or modeled articulator positions, it does not rely on any particular model of sound propagation through the vocal tract, and it recovers a mapping from acoustics to articulator positions that is linearly, not topographically, related to the actual mapping from acoustics to articulation. The approach categorizes short-time windows of speech into a finite number of sound types, and assumes the probability of using any articulator position to produce a given sound type can be described by a parameterized probability density function. MALCOM then uses maximum likelihood estimation techniques to: (1) find the most likely smooth articulator path given a speech sample and a set of distribution functions (one distribution function for each sound type), and (2) change the parameters of the distribution functions to better account for the data. Using this technique improves the accuracy of articulator position estimates compared to continuity mapping -- the only other technique that learns the relationship between acoustics and articulation solely from acoustics. The technique has potential application to computer speech recognition, speech synthesis and coding, teaching the hearing impaired to speak, improving foreign language instruction, and teaching dyslexics to read. 34 refs., 7 figs.

  4. Design and operation of the JET articulated boom

    International Nuclear Information System (INIS)

    After tritium introduction, planned for JET about 1991, remote handling maintenance is vital to the continued operation of the machine. An articulated boom has been designed at JET as the sole support device for in-vessel transport of all equipment and servo-manipulators and is part of the JET Remote Handling plan. The boom was manufactured by NEI Thompson of Wolverhampton and AET of Coventry, England, delivered to JET in October 1984 and has been commissioned successfully to its full design performance. The boom has been used during the June 1985 maintenance period as a hands-on lifting device using a hand-held, push-button controller. Dynamic computer modelling of the boom has been carried out to analyse cross-coupling inertial effects arising in the horizontal plane. A/sup 1//5-scale, mechanical model has also been used to control the boom in a master-slave mode

    Bruce, Anne; Sheilds, Laurene; Molzahn, Anita

    2011-03-01

    Despite growing interest in spiritual matters throughout society, definitions and descriptions of spirituality seem incomplete or otherwise unsatisfactory. In this article, the authors consider the possibility that such incompleteness is perhaps necessary and welcomed in addressing spirituality. In particular, they investigate the challenges of using metaphor and metonymic approaches to "languaging" spirituality. By exploring these figures of speech they hope to diversify how nurses articulate deeply personal and perhaps enigmatic human phenomena such as spirituality. Metaphoric language uses everyday structures to help make sense of complex, emotional, and abstract experience. Whereas metaphor creates substitutive relationships between things and provides insights into conceptualizing spirituality, metonymy and metonymic writing establish relationships of contiguity. Whereas metaphor functions to represent and facilitates understanding and feelings about spirituality, metonymy disrupts while opening possibilities of moving beyond binary thinking. Attending to language and its various ontological assumptions opens diverse and potentially more inclusive possibilities. PMID:20841392

    1981-01-01

    The Voyager attitude and articulation control system is designed for a three-axis stabilized spacecraft; it uses a biasable sun sensor and a Canopus Star Tracker (CST) for celestial control, as well as a dry inertial reference unit, comprised of three dual-axis dry gryos, for inertial control. A series of complex maneuvers was required during the first of two Voyager spacecraft encounters with Saturn (November 13, 1980); these maneuvers involved rotating the spacecraft simultaneously about two or three axes while maintaining accurate pointing of the scan platform. Titan and Saturn earth occulation experiments and a ring scattering experiment are described. Target motion compensation and the effects of celestial sensor interference are also considered. Failure of the CST, which required an extensive reevaluation of the star reference and attitude control mode strategy, is discussed. Results analyzed thus far show that the system performed with high accuracy, gathering data deeper into Saturn's atmosphere than on any previous planetary encounter.

  7. Sensory Integration with Articulated Motion on a Humanoid Robot

    2005-01-01

    Full Text Available This paper describes the integration of articulated motion with auditory and visual sensory information that enables a humanoid robot to achieve certain reflex actions that mimic those of people. Reflexes such as reach-and-grasp behavior enables the robot to learn, through experience, its own state and that of the world. A humanoid robot with binaural audio input, stereo vision, and pneumatic arms and hands exhibited tightly coupled sensory-motor behaviors in four different demonstrations. The complexity of successive demonstrations was increased to show that the reflexive sensory-motor behaviors combine to perform increasingly complex tasks. The humanoid robot executed these tasks effectively and established the groundwork for the further development of hardware and software systems, sensory-motor vector-space representations, and coupling with higher-level cognition.

  8. Does silent reading involve articulation? Evidence from tongue twisters.

    Science.gov (United States)

    Haber, L R; Haber, R N

    1982-01-01

    To demonstrate an interfering effect of subvocal articulation on otherwise silent reading, college-student subjects were asked to repeatedly read, either silently or aloud, both tongue-twister sentences and control sentences matched for syntactic complexity, syllable count, and sentential stress pattern. A technique was developed to measure the amount of time needed for each repetition of a sentence whether done silently or aloud. A significant difference in reading time for tongue twisters as compared to their matched controls was found for both silent as well as out-loud reading. A variety of different kinds of articulatory errors occurred in the oral repetitions, and the number of such errors was highly correlated with oral reading time. While errors could not be measured in silent reading, this correlation suggested that comparable articulatory disturbances accounted for the slower time to silently repeat tongue twisters.

    We present two data-driven importance distributions for particle filterbased articulated tracking; one based on background subtraction, another on depth information. In order to keep the algorithms efficient, we represent human poses in terms of spatial joint positions. To ensure constant bone...... lengths, the joint positions are confined to a non-linear representation manifold embedded in a high-dimensional Euclidean space. We define the importance distributions in the embedding space and project them onto the representation manifold. The resulting importance distributions are used in a particle...... filter, where they improve both accuracy and efficiency of the tracker. In fact, they triple the effective number of samples compared to the most commonly used importance distribution at little extra computational cost....

  11. The complete mitochondrial genome of Articulate Brachiopod Terebratal ia transversa

    Energy Technology Data Exchange (ETDEWEB)

    Helfenbein, Kevin G.; Brown, Wesley M.; Boore, Jeffrey L.

    2001-07-01

    We have sequenced the complete mitochondrial DNA (mtDNA) of the articulate brachiopod Terebratalia transversa. The circular genome is 14,291 bp in size, relatively small compared to other published metazoan mtDNAs. The 37 genes commonly found in animal mtDNA are present; the size decrease is due to the truncation of several tRNA, rRNA, and protein genes, to some nucleotide overlaps, and to a paucity of non-coding nucleotides. Although the gene arrangement differs radically from those reported for other metazoans, some gene junctions are shared with two other articulate brachiopods, Laqueus rubellus and Terebratulina retusa. All genes in the T. transversa mtDNA, unlike those in most metazoan mtDNAs reported, are encoded by the same strand. The A+T content (59.1 percent) is low for a metazoan mtDNA, and there is a high propensity for homopolymer runs and a strong base-compositional strand bias. The coding strand is quite G+T-rich, a skew that is shared by the confamilial (laqueid) specie s L. rubellus, but opposite to that found in T. retusa, a cancellothyridid. These compositional skews are strongly reflected in the codon usage patterns and the amino acid compositions of the mitochondrial proteins, with markedly different usage observed between T. retusa and the two laqueids. This observation, plus the similarity of the laqueid non-coding regions to the reverse complement of the non-coding region of the cancellothyridid, suggest that an inversion that resulted in a reversal in the direction of first-strand replication has occurred in one of the two lineages. In addition to the presence of one non-coding region in T. transversa that is comparable to those in the other brachiopod mtDNAs, there are two others with the potential to form secondary structures; one or both of these may be involved in the process of transcript cleavage.

    Full Text Available Context: The precision of an arbitrary face-bow in accurately transferring the orientation of the maxillary cast to the articulator has been questioned because the maxillary cast is mounted in relation to arbitrary measurements and anatomic landmarks that vary among individuals. Aim: This study was intended to evaluate the sagittal inclination of mounted maxillary casts on two semi-adjustable articulator/face-bow systems in comparison to the occlusal cant on lateral cephalograms. Materials and Methods: Maxillary casts were mounted on the Hanau and Girrbach semi-adjustable articulators following face-bow transfer with their respective face-bows. The sagittal inclination of these casts was measured in relation to the fixed horizontal reference plane using physical measurements. Occlusal cant was measured on lateral cephalograms. SPSS software (version 11.0, Chicago, IL, USA was used for statistical analysis. Repeated measures analysis of variance and Tukey′s tests were used to evaluate the results (P < 0.05. Results: Comparison of the occlusal cant on the articulators and cephalogram revealed statistically significant differences. Occlusal plane was steeper on Girrbach Artex articulator in comparison to the Hanau articulator. Conclusion: Within the limitations of this study, it was found that the sagittal inclination of the mounted maxillary cast achieved with Hanau articulator was closer to the cephalometric occlusal cant as compared to that of the Girrbach articulator. Among the two articulators and face-bow systems, the steepness of sagittal inclination was greater on Girrbach semi-adjustable articulator. Different face-bow/articulator systems could result in different orientation of the maxillary cast, resulting in variation in stability, cuspal inclines and cuspal heights.

    A new method based on human-likeness assessment and optimization concept to solve the problem of human-like manipulation planning for articulated robot is proposed in this paper.This method intrinsically formulates the problem as a constrained optimization problem in robot configuration space.The robot configuration space is divided into different subregions by human likeness assessment.A widely used strategy,Rapid Upper Limb Assessment (RULA) in applied ergonomics,is adopted here to evaluate the human likeness of robot configuration.A task compatibility measurement of the robot velocity transmission ratio along a specified direction is used as the target function for the optimization problem.Simple illustrative examples of this method applied to a two Degree of Freedom (DOF) planar robot that resembles the upper limb of a human are presented.Further applications to a humanoid industrial robot SDA10D are also presented.The reasonable planning results for these applications assert the effectiveness of our method.

  18. Concepts first, jargon second improves student articulation of understanding.

    McDonnell, Lisa; Barker, Megan K; Wieman, Carl

    2016-01-01

    In this experiment, students in a large undergraduate biology course were first exposed to the concepts without new technical vocabulary ("jargon") in a pre-class reading assignment. Their learning of the concepts and jargon was compared with that of an equivalent group of students in another section of the same course, whose pre-class reading presented both the jargon and concepts together in the traditional manner. Both groups had the same active-learning classes with the same instructor, and then completed the same post-test. Although the two groups performed the same on the multiple choice questions of the post-test, the group exposed to concepts first and jargon second included 1.5 times and 2.5 times more correct arguments on two free-response questions about the concepts. The correct use of jargon between the two groups was similar, with the exception of one jargon term that the control group used more often. These results suggest that modest instructional changes whereby new concepts are introduced in a concepts-first, jargon-second manner can increase student learning, as demonstrated by their ability to articulate their understanding of new concepts.

    Full Text Available In this assay I have studied the structure of iẕlak which took place in disciplines that interested in Arabic phonetics in some way. The structure of iẕlak, in many field related to phonetics, has been used to express one of the conditions made by the organs during the process of producing speak sounds. But this structure didn’t mentioned in the earliest sources and in some of the latests. On the other hand we have noticed that the explanations of iẕlak term in the earliest works and the latest works of tacwid were different, and also that the new explanation was getting widely accepted. To follow this structure, which it’s all definitions were connected with its root meaning, we reviewed classical dictionaries, works concerned with Arabic language, tacwid works and other sources. The study has pointed out that although iẕlak is an affecting characteristic which influences the sound interactions, it is basically not an articulation subject.

  20. Missile guidance law design using adaptive cerebellar model articulation controller.

    Lin, Chih-Min; Peng, Ya-Fu

    2005-05-01

    An adaptive cerebellar model articulation controller (CMAC) is proposed for command to line-of-sight (CLOS) missile guidance law design. In this design, the three-dimensional (3-D) CLOS guidance problem is formulated as a tracking problem of a time-varying nonlinear system. The adaptive CMAC control system is comprised of a CMAC and a compensation controller. The CMAC control is used to imitate a feedback linearization control law and the compensation controller is utilized to compensate the difference between the feedback linearization control law and the CMAC control. The online adaptive law is derived based on the Lyapunov stability theorem to learn the weights of receptive-field basis functions in CMAC control. In addition, in order to relax the requirement of approximation error bound, an estimation law is derived to estimate the error bound. Then the adaptive CMAC control system is designed to achieve satisfactory tracking performance. Simulation results for different engagement scenarios illustrate the validity of the proposed adaptive CMAC-based guidance law. PMID:15940993

    Dental instrumentation has long provided insight into the mechanism of musculo-skeletal function of the gnathic system. While large population studies associate dental arch displacement (DAD), especially laterally, with symptoms, mandibular condyle displacement (CD) resulting from DAD has not been targeted as possibly etiologic in the production of common muscle contraction headache (CMCH) and temporo-mandibular dysfunction (TMD). The objective was to evaluate the three-dimensional nature of DAD and CD between the seated condylar position (SCP) and the intercuspal position (ICP) and to compare results derived from large deprogrammed asymptomatic and symptomatic populations. A total of 1 192 sets of dental casts collected from asymptomatic and symptomatic populations were articulated in the SCP. The initial occlusal contact, DAD, and condylar displacement were evaluated for frequency, direction, and magnitude of displacement between the SCP and ICP. The data revealed significant displacement between the SCP and ICP of the condyles (displaced most frequently inferior (down) and posterior (distal)) and substantially increased frequency and magnitude of displacement of the dental arches (with posterior premature occlusal contacts, increased overjet, decreased overbite, midline differences, and occlusal classification changes) in symptomatic subjects. These discrepancies were statistically significant and clinically significant. The data support the concept of increased DAD and CD with dysfunction. Transverse condylar displacement, commonly presenting with dental cross bite, may be associated with CMCH and TMD. Displacement of the mandibular condyle may be an etiologic factor in CMCH and dysfunction of the temporo-mandibular joint. PMID:27357324

    With the goal of providing assistive technology for the communication impaired, we proposed electroencephalography (EEG) cortical currents as a new approach for EEG-based brain-computer interface spellers. EEG cortical currents were estimated with a variational Bayesian method that uses functional magnetic resonance imaging (fMRI) data as a hierarchical prior. EEG and fMRI data were recorded from ten healthy participants during covert articulation of Japanese vowels /a/ and /i/, as well as during a no-imagery control task. Applying a sparse logistic regression (SLR) method to classify the three tasks, mean classification accuracy using EEG cortical currents was significantly higher than that using EEG sensor signals and was also comparable to accuracies in previous studies using electrocorticography. SLR weight analysis revealed vertices of EEG cortical currents that were highly contributive to classification for each participant, and the vertices showed discriminative time series signals according to the three tasks. Furthermore, functional connectivity analysis focusing on the highly contributive vertices revealed positive and negative correlations among areas related to speech processing. As the same findings were not observed using EEG sensor signals, our results demonstrate the potential utility of EEG cortical currents not only for engineering purposes such as brain-computer interfaces but also for neuroscientific purposes such as the identification of neural signaling related to language processing.

    2011-01-01

    Given a point cloud, we consider inferring kinematic models of 3D articulated objects such as boxes for the purpose of manipulating them. While previous work has shown how to extract a planar kinematic model (often represented as a linear chain), such planar models do not apply to 3D objects that are composed of segments often linked to the other segments in cyclic configurations. We present an approach for building a model that captures the relation between the input point cloud features and the object segment as well as the relation between the neighboring object segments. We use a conditional random field that allows us to model the dependencies between different segments of the object. We test our approach on inferring the kinematic structure from partial and noisy point cloud data for a wide variety of boxes including cake boxes, pizza boxes, and cardboard cartons of several sizes. The inferred structure enables our robot to successfully close these boxes by manipulating the flaps.

  5. Visibility of speech articulation enhances auditory phonetic convergence.

    Science.gov (United States)

    Dias, James W; Rosenblum, Lawrence D

    2016-01-01

    Talkers automatically imitate aspects of perceived speech, a phenomenon known as phonetic convergence. Talkers have previously been found to converge to auditory and visual speech information. Furthermore, talkers converge more to the speech of a conversational partner who is seen and heard, relative to one who is just heard (Dias & Rosenblum Perception, 40, 1457-1466, 2011). A question raised by this finding is what visual information facilitates the enhancement effect. In the following experiments, we investigated the possible contributions of visible speech articulation to visual enhancement of phonetic convergence within the noninteractive context of a shadowing task. In Experiment 1, we examined the influence of the visibility of a talker on phonetic convergence when shadowing auditory speech either in the clear or in low-level auditory noise. The results suggest that visual speech can compensate for convergence that is reduced by auditory noise masking. Experiment 2 further established the visibility of articulatory mouth movements as being important to the visual enhancement of phonetic convergence. Furthermore, the word frequency and phonological neighborhood density characteristics of the words shadowed were found to significantly predict phonetic convergence in both experiments. Consistent with previous findings (e.g., Goldinger Psychological Review, 105, 251-279, 1998), phonetic convergence was greater when shadowing low-frequency words. Convergence was also found to be greater for low-density words, contrasting with previous predictions of the effect of phonological neighborhood density on auditory phonetic convergence (e.g., Pardo, Jordan, Mallari, Scanlon, & Lewandowski Journal of Memory and Language, 69, 183-195, 2013). Implications of the results for a gestural account of phonetic convergence are discussed. PMID:26358471

  6. Zootherapy in Recife (Pernambuco, Brasil: articulating history and practice

    Full Text Available The use of animals in therapeutic practices has been a reality throughout human history, although it is not yet a well understood phenomenon. The main objective of this study was to describe and analyze the use of medicinal fauna in Recife, Pernambuco State, Brazil. Many aspects were taken into account, such as the identification of the animals used, preparation of the zootherapeutic products, and the articulation between current popular practices and the history of zootherapy in the region. Data were collected through semi-structured, open-ended interviews conducted with folk specialists in three public markets of Recife. For purposes of historical revision, data were also taken from the books written by two naturalists who lived in Pernambuco during the Dutch occupation: Guilherme Piso and Jorge Marcgrave. During the survey in public markets, 18 ethnotaxonomic categories of animals were found to be in current use for the treatment of 12 diseases, according to the popular medicinal diagnosis. In these cases, the prescriptions were characterized by dosage recommendation, association with plant products, and certain cultural rules. Among these 18 ethnocategories, 9 were similar to those used in the 17th century. These were used, during the Dutch occupation, for the preparation of 9 different kinds of medicines, which treated 10 diseases. Nevertheless, in most cases the current popular prescriptions differ from those reported in the colonial period. The results show the strong persistence of zootherapy in the region, since the reported diseases take part in the daily life of poor local people. Further studies on this body of knowledge, beliefs and popular practices may be a helpful tool for medical and pharmaceutical investigations, as well as for a better understanding of the interaction between local people and natural resources and conservation, in a historical perspective.

  7. The cognitive skill of theory articulation: A neglected aspect of science education?

    1992-06-01

    It is argued that scientific literacy requires that students know how to apply scientific theories. However, the process of articulating a theory with respect to a particular phenomenon, fact, or regularity is quite complex. Also, the procedures used to apply a theory are not part of the theory itself, and therefore are not necessarily learned by studying the content of the theory. It follows that the skill of theory articulation has to be taught explicitly. A preliminary analysis of textbooks and tests indicates that this is not currently done. Recent research on science education has not focussed on theory articulation, but Roger C. Schank's theory of explanation provides a starting point.

    Low power Electromagnetic (EM) Wave sensors can measure general properties of human speech articulator motions, as speech is produced. See Holzrichter, Burnett, Ng, and Lea, J.Acoust.Soc.Am. 103 (1) 622 (1998). Experiments have demonstrated extremely accurate pitch measurements (< 1 Hz per pitch cycle) and accurate onset of voiced speech. Recent measurements of pressure-induced tracheal motions enable very good spectra and amplitude estimates of a voiced excitation function. The use of the measured excitation functions and pitch synchronous processing enable the determination of each pitch cycle of an accurate transfer function and, indirectly, of the corresponding articulator motions. In addition, direct measurements have been made of EM wave reflections from articulator interfaces, including jaw, tongue, and palate, simultaneously with acoustic and glottal open/close signals. While several types of EM sensors are suitable for speech articulator measurements, the homodyne sensor has been found to provide good spatial and temporal resolution for several applications.

    Hofmann, Alex; Goebl, Werner

    2014-01-01

    This paper investigates the production and perception of different articulation techniques on the saxophone. In a production experiment, two melodies were recorded that required different effectors to play the tones (tongue-only actions, finger-only actions, combined tongue and finger actions) at three different tempi. A sensor saxophone reed was developed to monitor tongue-reed interactions during performance. In the slow tempo condition, combined tongue-finger actions showed improved timing, compared to the timing of the tongue alone. This observation supports the multiple timer hypothesis where the tongue's timekeeper benefits from a coupling to the timekeeper of the fingers. In the fast tempo condition, finger-only actions were less precise than tongue-only actions and timing precision of combined tongue-finger actions showed the higher timing variability, close to the level of finger-only actions. This suggests that the finger actions have a dominant influence on the overall timing of saxophone performance. In a listening experiment we investigated whether motor expertise in music performance influences the perception of articulation techniques in saxophone performance. Participants with different backgrounds in music making (saxophonists, musicians not playing the saxophone, and non-musicians) attended an AB-X listening test. They had to discriminate between saxophone phrases played with different articulation techniques (legato, portato, staccato). Participants across all three groups discriminated the sound of staccato articulation well from the sound of portato articulation and legato articulation. Errors occurred across all groups of listeners when legato articulation (no tonguing) and portato articulation (soft tonguing) had to be discriminated. Saxophonists' results were superior compared to the results of the other two groups, suggesting that expertise in saxophone playing facilitated the discrimination task. PMID:25076918

    Full Text Available Children with Attention-Deficiency/Hyperactive Disorder (ADHD often have co-existing learning disabilities and developmental weaknesses or delays in some areas including speech (Rief, 2005. Seeing that phonological disorders include articulation errors and other forms of speech disorders, studies pertaining to children with ADHD symptoms who demonstrate signs of phonological disorders in their native Arabic language are lacking. The purpose of this study is to provide a description of Arabic language deficits and to present a theoretical model of potential associations between phonological language deficits and ADHD. Dodd and McCormack’s (1995 four subgroups classification of speech disorder and the phonological disorders pertaining to the Arabic language provided by a Saudi Institute for Speech and Hearing are examined within the theoretical framework. Since intervention may improve articulation and focuses a child’s attention on the sound structure of words, findings in this study are based on the assumption that children with ADHD may acquire phonology for their Arabic language in the same way, and following the same developmental stages as intelligible children. Both quantitative and qualitative analyses have proven that the ADHD group analyzed in this study had indeed failed to acquire most of their Arabic consonants as they should have.Keywords: speech sound disorder, attention-deficiency/hyperactive, developmental disorder, phonological disorder, language disorder/delay, language impairment

    This study determined whether children could learn to replicate four positions of lingual-palatal contact with and without topical anesthesia that eliminated touch-pressure sensations. First-grade boys, nine with good articulation skills and nine with poor articulation skills, were used as subjects. Results suggest that individuals are able to learn nonspeech tasks of tongue positioning by relying on muscle spindles or deep receptors within the tongue, or both, or by relying on lingual touch-pressure or other surface receptors within the tongue, or, by a combination of deep and surface receptors of the tongue. Further, tongue positioning need not be dependent on touch-pressure or superficial tactile mechanisms. Children with relatively severe articulation problems performed more poorly on the tasks of precise tongue placement than children with good articulation skills. And finally, children with relatively severe articulation problems may be able to improve their initially poor performance on tongue placement tasks with specific training on those tasks, implying that this group did receive the intraoral sensory feedback necessary to learn the task, but that more experience was needed for the learning to occur.

    Full Text Available This paper designs an anti-rollover control system to improve articulated off-road vehicle rollover safety. This controller consists two level control which target to two different instability stages: 1 the active swing bridge adjustment control algorithm for the first stage instability; and 2 the active braking control algorithm for the second stage instability. The first level control is based on fuzzy PID control and second is based on switch control, they work together to prevent the articulated wheel loader from rollover accident. Multi-body dynamics model of a ZL50 articulated wheel loader is built by commercial software RecurDyn, and the MBD model and controller model were co-simulated under the same solver in RecurDyn/CoLink. The co-simulation results show that, during the high speed steering rollover process, these two level controller work efficiently to reduce the roll angle and improve the vehicle rollover stability.

    Full Text Available The aim of the present study is to examine acoustic characteristics of Moroccan fricatives in order to find invariant cues that classify fricatives into their place of articulation. Fricative consonants of Moroccan Arabic dialect were elicited from 8 adult speakers (4 male and 4 female in 3 vowel contexts (/i, a, u/. The cues investigated included temporal measurement (duration of fricative consonant and formant information at fricative-vowel transition (F1 and F2 at vowel onset and locus equation. The effects of voicing, speaker’s gender and post-fricative vowel on both formants onset values and locus equations were investigated. The results obtained showed that F1 onset values differentiated voiceless from voiced fricatives. F2 onset values distinguished fricatives in term of place of articulation. The locus equation slope and intercept differentiated voiceless from voiced fricative and distinguished clearly palatal fricatives from the other places of articulation

  8. Development of a Wave Energy -Responsive Self-Actuated Blade Articulation Mechanism for an OWC Turbine

    The Phase I SBIR effort completed the feasibility design, fabrication, and wind tunnel testing of a self-actuated blade articulation mechanism that uses a torsion bar and a lightweight airfoil to affect the articulation of the Wells airfoil. The articulation is affected only by the air stream incident on the airfoil. The self-actuating blade eliminates the complex and costly linkage mechanism that is now needed to perform this function on either a variable pitch Wells-type or Dennis-Auld air turbine. Using the results reported by independent researchers, the projected improvement in the Wells-type turbine efficiency is 20-40%, in addition to an increase in the operating air flow range by 50-100%, therefore enabling a smaller or slower single turbine to be used.

  9. Dynamic of articulated systems with deformable or undeformable structures. Robotic application

    International Nuclear Information System (INIS)

    The rapid developments in robotics, as well as the increasing complexity of the associated mechanical devices, show the interest for a numerical code to handle mechanisms problems. It is necessary to take into account the specific properties of articulated systems. In particular, large displacements have to be considered, while quasi-rigid structures are related through various articulations, which have to be modeled. Deformability also becomes important, as soon as the spead increases. The developments now carried out in the PLEXUS code of the CASTEM Finite Element System, will allow this program to be suitable tool to handle mechanisms problems

  6. The difference practice makes: Evidence, articulation, and affect in HIV prevention.

    Race, Kane

    2014-06-01

    This paper considers the difference that a conception of sex as social practice has made to the relations articulated in HIV social research in Australia. In defining sexual practice as "fluid, embedded in specific social formations, and involving the negotiation of meaning" (Kippax & Stephenson, 2005), social researchers put their own research categories and questions at risk by constructing situations in which the objects of research were given occasions to counter researchers' presumptions through the use of their own categories. Taking this risk produced sharp insights about the evolving dynamics of gay sexuality in this context and produced distinctive, interesting findings. It enabled the articulation of the practice of negotiated safety and later strategies of HIV risk reduction emerging from gay men's practice, for example. I draw on Latour's (2004) concept of articulation to make sense of these innovations and cut through some of the key distinctions that organize HIV research: qualitative/quantitative; social/biomedical; subject/ object; human/nonhuman; interpretations/evidence. Rather than rest on the organizing power of these distinctions, keeping HIV prevention effective, engaging and interesting will require specific attention to the embodied articulation of HIV relations in the present.

    Full Text Available Laparoscopy requires the development of technical skills distinct from those used in open procedures. Several factors extending the learning curve of laparoscopy include ergonomic and technical difficulties, such as the fulcrum effect and limited degrees of freedom. This study aimed to establish the impact of four variables on performance of two simulated laparoscopic tasks. Methods: Six subjects including novice (n=2, intermediate (n=2 and expert surgeons completed two tasks: 1 four running sutures, 2 simple suture followed by surgeon′s knot plus four square knots. Task variables were suturing angle (left/right, needle holder type (standard/articulating and visualisation (2D/3D. Each task with a given set of variables was completed twice in random order. The endpoints included suturing task completion time, average and maximum distance from marks and knot tying task completion time. Results: Suturing task completion time was prolonged by 45-degree right angle suturing, articulating needle holder use and lower skill levels (all P < 0.0001. Accuracy also decreased with articulating needle holder use (both P < 0.0001. 3D vision affected only maximum distance ( P =0.0108. For the knot tying task, completion time was greater with 45-degree right angle suturing ( P =0.0015, articulating needle holder use ( P < 0.0001, 3D vision ( P =0.0014 and novice skill level ( P =0.0003. Participants felt that 3D visualisation offered subjective advantages during training. Conclusions: Results suggest construct validity. A 3D personal head display and articulating needle holder do not immediately improve task completion times or accuracy and may increase the training burden of laparoscopic suturing and knot tying.

    Full Text Available The objective of this study was to describe the process of intensive speech therapy for a 6-year-old child using compensatory articulations while presenting with velopharyngeal insufficiency (VPI and a history of cleft lip and palate. The correction of VPI was temporarily done with a pharyngeal obturator since the child presented with very little movement of the pharyngeal walls during speech, compromising the outcome of a possible pharyngeal flap procedure (pharyngoplasty. The program of intensive speech therapy involved 3 phases, each for duration of 2 weeks incorporating 2 daily sessions of 50 minutes of therapy. A total of 60 sessions of intervention were done with the initial goal of eliminating the use of compensatory articulations. Evaluation before the program indicated the use of co-productions (coarticulations of voiceless plosive and fricative sounds with glottal stops (simultaneous production of 2 places of productions, along with weak intraoral pressure and hypernasality, all compromising speech intelligibility. To address place of articulation, strategies to increase intraoral air pressure were used along with visual, auditory and tactile feedback, emphasizing the therapy target and the air pressure and airflow during plosive and fricative sound productions. After the first two phases of the program, oral place of articulation of the targets were achieved consistently. During the third phase, velopharyngeal closure during speech was systematically addressed using a bulb reduction program with the objective of achieving velopharyngeal closure during speech consistently. After the intensive speech therapy program involving the use of a pharyngeal obturator, we observed absence of hypernasality and compensatory articulation with improved speech intelligibility.

    Borderline personality disorder (BPD) is a severe, difficult-to-treat psychiatric condition that represents a large proportion of treatment-seeking individuals. BPD is characterized by high rates of co-occurrence with depressive and anxiety disorders, and recently articulated conceptualizations of this comorbidity suggest that these disorders may result from common temperamental vulnerabilities and functional maintenance factors. The Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) was developed to address these shared features relevant across frequently co-occurring disorders. The purpose of the present study was to explore the preliminary efficacy of the UP for treatment of BPD with comorbid depressive and/or anxiety disorders in a clinical replication series consisting of five cases. For the majority of cases, the UP resulted in clinically significantly decreases in BPD, anxiety, and depressive symptoms, as well as increases in emotion regulation skills. PMID:25710737

There is also a brief note on contextuality, on the spoken and written norms of language and on the poetic and specialized languages/styles, all as related to word order.The FSP is seen as one type of structuring sentence linearity. As such, the FSP is considered to be an important, more recent parallel to the contemporary varieties of what is here called ordinary structuring (articulation, i.e. types of grammatical subject-predicate structuring (articulation. In contrast to ‘ordinary’ approaches, the FSP structuring is supported by communicatively oriented pragma-psycho-linguistic foundations, i.e. using key terms like situation of communication, addresser intention, addressee response, etc. That is why the next step is to compare the two conceptions (FSP and ordinary structuring. The main result of the comparison is the parallel nature of the two : They share texts to analyze and, to do so, they use different principles and terminologies (see the table of terms in section 8. The successful contemporary development of FSP, as well as its pioneerig steps in the pre-1945 period, have been made mainly by Prague linguists, who, together with a number of interested scholars from abroad, work out its theory trying to make of it a standard component of syntactic research.

  14. Development and evaluation of an articulated registration algorithm for human skeleton registration

    International Nuclear Information System (INIS)

    Accurate registration over multiple scans is necessary to assess treatment response of bone diseases (e.g. metastatic bone lesions). This study aimed to develop and evaluate an articulated registration algorithm for the whole-body skeleton registration in human patients. In articulated registration, whole-body skeletons are registered by auto-segmenting into individual bones using atlas-based segmentation, and then rigidly aligning them. Sixteen patients (weight = 80–117 kg, height = 168–191 cm) with advanced prostate cancer underwent the pre- and mid-treatment PET/CT scans over a course of cancer therapy. Skeletons were extracted from the CT images by thresholding (HU>150). Skeletons were registered using the articulated, rigid, and deformable registration algorithms to account for position and postural variability between scans. The inter-observers agreement in the atlas creation, the agreement between the manually and atlas-based segmented bones, and the registration performances of all three registration algorithms were all assessed using the Dice similarity index—DSIobserved, DSIatlas, and DSIregister. Hausdorff distance (dHausdorff) of the registered skeletons was also used for registration evaluation. Nearly negligible inter-observers variability was found in the bone atlases creation as the DSIobserver was 96 ± 2%. Atlas-based and manual segmented bones were in excellent agreement with DSIatlas of 90 ± 3%. Articulated (DSIregsiter = 75 ± 2%, dHausdorff = 0.37 ± 0.08 cm) and deformable registration algorithms (DSIregister = 77 ± 3%, dHausdorff = 0.34 ± 0.08 cm) considerably outperformed the rigid registration algorithm (DSIregsiter = 59 ± 9%, dHausdorff = 0.69 ± 0.20 cm) in the skeleton registration as the rigid registration algorithm failed to capture the skeleton flexibility in the joints. Despite superior skeleton registration performance, deformable registration algorithm failed to preserve the local rigidity of bones as over

  15. Investigation of radiation exposure of medical staff: Measurements supported by simulations with an articulated hand phantom

    International Nuclear Information System (INIS)

    To evaluate and optimise extremity doses in nuclear medicine, work package 4 of the ORAMED project () focussed on investigating skin doses of nuclear medicine worker hands. In addition to a measurement campaign, selected scenarios were simulated by means of hand wax phantoms. The phantoms were modelled according to the scenario of radiopharmaceutical syringe handling. The wax phantoms in the position of interest were scanned and introduced as lattice (voxel) geometry into the simulation input geometry. In this article the mathematical articulated hand model developed at KIT () is compared to these models. This mathematical hand phantom consists of rigid and flexible elements, allowing for an adaptable anatomy and flexible hand poses. In contrast to the static voxel models obtained by a complex procedure based on CT-scanned images, the articulated hand phantom can be used comparably simply for differing scenarios.

    Full Text Available This paper describes the application of an alternative seating system. The aim of this alternative approach was to determine the comfort of offi ce armchairs equipped with new construction solutions ensuring articulated support of the seat as well as articulated mounting of the gas spring. An offi ce armchair with a different seat support and gas spring was selected. Operational loads were applied to the seat surface. The following parameters were measured and calculated in the course of the performed experiments: contact area, average contact pressure and coeffi cient of seat pressure distribution (SPD. A new discomfort coeffi cient D expressing seat quality was elaborated. Preliminary data suggests that the prototypes provided greater sitting comfort than did the conventional chair. It was demonstrated that the new construction solution of the gas spring support guaranteed the highest comfort of the use of the examined armchairs.

  17. Stress analysis of an articulated boom for in-vessel-handling of fusion reactors

    International Nuclear Information System (INIS)

    Due to the high radioactivity levels, in-vessel maintenance work in the plasma chamber of a tokamak fusion machine can be done only by remote handling equipment, which is introduced into the torus-type plasma chamber by means of an articulated boom. The remote handling units have to be operated without any support provided for at the walls of the plasma chamber. A new articulated boom design is currently developed in the KfK for the NET project. This device is to bear at its tip working loads of up to 3900 kg (max. weight of remote handling equipment 2900 kg, of interchangeable components 1000 kg). In order to allow as precise manipulation as possible, the degree of sogging of the boom tip under its own load or under the working load has to be kept as small as possible. (orig./DG)

    Dental prosthesis is a foreign body in oral cavity and thus necessarily interferes with speech articulation. The purpose of this study was to examine influence of partial denture on speech quality and to show eventual differences in pronunciation of dental sounds c, z, s and postalveolar sounds č, ž and š. We have examined differences in pronunciation between subjects with removable partial dentures, the same group without partial dentures and a control group. The study was performed on 30 su...

    A facial tissue model, articulated by synthetic muscles, provides a tool for observing, analyzing, and predicting soft tissue mobility on the face. A geometric model of facial tissue extracted from CT data improves the skin tissue simulation by using accurate skin tissue depths. This paper suggests that the ability to control the model resolution, muscle placement and activity requires an integrated modeling and animation system.

  20. Standard conforming involute gear metrology using an articulated arm coordinate measuring system

    International Nuclear Information System (INIS)

    Standard conforming involute gear measurements were taken by a manually operating articulated arm system and the respective task-specific measurement uncertainties were estimated. User-friendly templates were developed to provide almost unambiguous and repeatable measurement results. They allow the metrologist to easily detect and gather the single measurement points according to existing guidelines and standards commonly used in gear metrology. The research activities were carried out at the Physikalisch-Technische Bundesanstalt (PTB), Germany in the Department of Coordinate Metrology. Measurements were taken on a robust and highly accurate large gear measurement standard of PTB, in the following called the gear standard. This gear standard materializes a left-hand and a right-hand gear as well as a spur gear. The 1 m outside diameter of the gear standard is similar to the gears used in wind power plants. A commercial articulated arm coordinate measuring system was used for the measurements. A high temperature stability of ±0.2 °C was provided to minimize thermal influences. The results of profile and helix measurements will be presented. This worldwide first investigation, on the basis of a calibrated involute gear standard, gives users of the articulating arm system quantitative information on a task-specific performance of a representative gear measurement.

  1. Integrating conventional and CAD/CAM digital techniques for establishing canine protected articulation: A clinical report.

    Science.gov (United States)

    El Kerdani, Tarek; Nimmo, Arthur

    2016-05-01

    Canine protected articulation is widely accepted for patients requiring extensive oral rehabilitation. Computer-aided design and computer-aided manufacturing (CAD/CAM) restorations have been primarily designed in occlusion at the maximum intercuspal position. Designing a virtual articulator that is capable of accepting excursive occlusal records and duplicating the mandibular movements is a challenge for CAD/CAM technology. Modifying tooth shape using composite resin trial restorations to produce esthetic results and later scanning the modified teeth to create milled crowns is becoming a popular use of the CAD/CAM technology. This report describes a technique that combines conventional and CAD/CAM prosthodontic techniques for milling crowns for canine teeth that are designed to establish or improve canine protected articulation. This technique involves designing and fabricating interim restorations based on diagnostic waxing, scanning the designs intraorally, and storing them in software as pretreatment digital records. The scanned designs are then applied to the digital representation of the prepared teeth to fabricate the definitive restorations. PMID:26774319

    2004-01-01

    This research explored the effects of instructing first-semester nursing students in the use of focused reflection and articulation to promote clinical reasoning. Student volunteers were randomly assigned to four clinical groups. Two groups that received instruction in the use of focused reflection and articulation scored significantly higher on the practice measure of clinical reasoning, accounting for 29 percent of the variance between groups. Once clinical reasoning scores were tabulated, the top six and bottom six scorers on clinical reasoning were interviewed to identify qualitative differences between students with different reasoning levels. Themes from the interviews revealed that those with high clinical reasoning reported a high frequency of use of focused reflection and articulation, engaged in abstract learning, and were more self-regulated in their learning than those who scored low on clinical reasoning. This study provides empirical evidence that using instructional methods that focus learners' attention on the concrete application of theory in the practicum setting helps enhance their reasoning skills.

  3. Integrated neurobiology of bipolar disorder

    Directory of Open Access Journals (Sweden)

    Vladimir eMaletic

    2014-08-01

    Full Text Available From a neurobiological perspective there is no such thing as bipolar disorder. Rather, it is almost certainly the case that many somewhat similar, but subtly different, pathological conditions produce a disease state that we currently diagnose as bipolarity. This heterogeneity—reflected in the lack of synergy between our current diagnostic schema and our rapidly advancing scientific understanding of the condition—limits attempts to articulate an integrated perspective on bipolar disorder. However, despite these challenges, scientific findings in recent years are beginning to offer a provisional unified field theory of the disease. This theory sees bipolar disorder as a suite of related neurodevelopmental conditions with interconnected functional abnormalities that often appear early in life and worsen over time. In addition to accelerated loss of volume in brain areas known to be essential for mood regulation and cognitive function, consistent findings have emerged at a cellular level, providing evidence that bipolar disorder is reliably associated with dysregulation of glial-neuronal interactions. Among these glial elements are microglia—the brain’s primary immune elements, which appear to be overactive in the context of bipolarity. Multiple studies now indicate that inflammation is also increased in the periphery of the body in both the depressive and manic phases of the illness, with at least some return to normality in the euthymic state. These findings are consistent with changes in the HPA axis, which are known to drive inflammatory activation. In summary, the very fact that no single gene, pathway or brain abnormality is likely to ever account for the condition is itself an extremely important first step in better articulating an integrated perspective on both its ontological status and pathogenesis. Whether this perspective will translate into the discovery of innumerable more homogeneous forms of bipolarity is one of the great

  7. Value of acoustic perceptual method for analysis of compensatory articulation errors in postoperative patients with cleft palate

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective To establish an acoustic perceptual method analyzing the compensatory articulation errors in children with operated cleft palate via the formants of Chinese pure vowels. Methods The first three formants which represent vocal transmission character in Chinese pure vowels of 84 subjects with operated cleft palate, were measured by Computerized Speech Signal Processing System (CSSPS). The Chinese vowel graph of postoperative patients with cleft palate was stated by the first formant frequencies (F1) and the second formant frequencies (F2) of the Chinese pure vowels between the two groups. Results Values of F1 and F2 of vowels except [a] in the poor articulation group (Group A) were significantly different from those in the good articulation group (Group B) (P<0.05 or P<0.01). As compared with that in Group B, the vowel graph demonstrated the decreased perceptual distances in Group A. These findings indicated that there might still be the backward movements of tongue, perverted mandibular movements and disharmonious lip movements in addition to the velopharyngeal insufficiency (VPI) in Group A. Conclusion The speech articulation of children with repaired cleft palate should be gained by correcting the aberrant compensatory articulation errors in the condition of velopharyngeal competence. Computerized Speech Signal Processing System (CSSPS), which is regarded as the content of objective quantitative measurement, is a precise, simple, reliable and atroumatic technique for children with cleft palate to analyze pathological compensatory articulation errors.

    1992-05-01

    Full Text Available The paper focuses on issues raised by Conrad’s Heart of Darkness and on ways in which two recent novels, The Expedition to the Baobab Tree (Stockenstrdni and The Whales in Lake Tanganyika (Hagerfors employ the same model of the journey of exploration in order to break down phallo- and eurocentric concepts of language in an attempt to arrive at a new articulation of Africa. In Heart of Darkness Marlow crosses the limits of language in his confrontation with the Other (Kurtz, and Africa, both of which have a female dimension and has to invent a ‘new’ language, post facto, to explain his discovery to the Woman who awaits him at the other end. In the Stockenstrdm text, the narrator and central personage is already female, but she is illiterate; and in order to articulate her body, in which her journey is subsumed, an implied narrator may have to narrate on her behalf, in a language which first has to liberate itself from the processes of bondage and appropriation to which the slave woman has been subjected all her life. In The Whales in Lake Tanganyika an interiext arises from the dialogue of this narrative with H.M. Stanley's historical journal; and this projects the diarist Shaw as the deconstructor of male and European dichotomies. Shedding conventional langitage, linearity and 'reality’, his diary becomes the translation of an inaccessible ‘new’ language which is the only way in which Spivak’s 'subaltern’ can attain speech to articulate the femininity implicit in Africa.

    2014-11-01

    Full Text Available Back ground: The vulnerability of the buffalo to the luxation of the hip articulation previous to and during parturition encouraged the investigation in this species. The literature reviewed did not reveal complete anatomical descriptions of the coxofemoral articulation of buffalo. Hence the study was undertaken. Purpose: to study the different anatomical aspects of the hip joint which are specific to buffaloes. Methods and Results: A total number of fifteen hip joints of buffalo calves procured from the local slaughter house and department of Veterinary Anatomy were studied in the Department of Veterinary Anatomy, College of Veterinary Science, Tirupati irrespective of breed, sex and nutritional status. The gross morphology of joints and relations were studied. The round ligament of buffalo was stronger compared to cattle. A thick fibrous stratum of articular capsule was present. A few arched and semi-circular fibers were seen in the articular capsule but zona orbicularis was absent. The best developed periarticular ligament in the buffalo hip was the iliofemoral ligament. It was a thick cord of connective tissue extending from a nodule below and behind the ischiatic spine and spreaded over the capsula articularis and finally attached to the trochanter major and trochanteric ridge. The pubocapsular ligament was located on the ventral surface of the joint capsule and blended with it. Compared to the most of other quadripeds the periarticular ligaments were well developed in buffalo. The iliofemoral ligament was mostly helpful in preventing the hip from excessive extension and adduction. The relative development of the periarticular ligaments in the biped and quadrupeds were probably in accordance with comparative weight that this articulation must support. Potential implications: An understanding of the basic anatomy of the hip helps in understanding pathology and can greatly assist the surgeon in appropriately diagnosing and treating the

  11. The articulation of Mexico into the dynamics of competition of the North American natural gas market

    International Nuclear Information System (INIS)

    Deregulation is at the origin of the new dynamics of competition in the natural gas industry. The United States and Canada were the pioneer countries to suffer these changes. In fact, their natural gas markets today function in a very similar way: i) the private sector takes a place as large as possible, and ii)competition is developed within the three segments of the gas value, especially at the upstream level (emergence of hubs, spot and financial markets,...). In Mexico, its downstream gas activities (transportation, storage and distribution) were liberalized in 1995 in order to attract private investments and to develop the gas sector that has historically been operated under State control. Gas upstream operations remain reserved by the Constitution to the national oil company Petroleos Mexicanos (PEMEX). This thesis develops an evaluation framework of the articulation of Mexico into the dynamics of competition of the North American natural gas market, based on the structure-conduct-performance paradigm. In the first part, all North American's natural gas industries base conditions are analyzed. We examine in the second part, the deregulation and articulation of the dynamics of competition of the American and Canadian gas industries. Finally, in the third part we analyze the main elements of the articulation of Mexico into the dynamics of competition of United States and Canada's gas industries. Furthermore, we evaluate the impact of three of these elements (the economic growth, the electric power generation sector and eventually opening to private investments of gas upstream activities) on the adjustment of gas supply and demand in Mexico to the year 2020.

    We developed and validated a fully articulated model of the thoracolumbar spine in opensim that includes the individual vertebrae, ribs, and sternum. To ensure trunk muscles in the model accurately represent muscles in vivo, we used a novel approach to adjust muscle cross-sectional area (CSA) and position using computed tomography (CT) scans of the trunk sampled from a community-based cohort. Model predictions of vertebral compressive loading and trunk muscle tension were highly correlated to previous in vivo measures of intradiscal pressure (IDP), vertebral loading from telemeterized implants and trunk muscle myoelectric activity recorded by electromyography (EMG).

    Energy Technology Data Exchange (ETDEWEB)

    Barnes, T; Burnett, G C; Holzrichter, J F

    1999-06-29

    Very low power, short-range microwave ''radar-like'' sensors can measure the motions and vibrations of internal human speech articulators as speech is produced. In these animate (and also in inanimate acoustic systems) microwave sensors can measure vibration information associated with excitation sources and other interfaces. These data, together with the corresponding acoustic data, enable the calculation of system transfer functions. This information appears to be useful for a surprisingly wide range of applications such as speech coding and recognition, speaker or object identification, speech and musical instrument synthesis, noise cancellation, and other applications.

    2012-01-01

    We consider the possible advantages of visualization in supporting musical interpretation. Specifically, we investigate the use of visualizations in making a subjective judgement of a student's performance compared to reference "expert" performance for particular aspects of musical performance-articulation and dynamics. Our assessment criteria for the effectiveness of the feedback are based on the consistency of judgements made by the participants using each modality, that is to say, in determining how well the student musician matches the reference musician, the time taken to evaluate each pair of samples, and subjective opinion of perceived utility of the feedback. For articulation, differences in the mean scores assigned by the participants to the reference versus the student performance were not statistically significant for each modality. This suggests that while the visualization strategy did not offer any advantage over presentation of the samples by audio playback alone, visualization nevertheless provided sufficient information to make similar ratings. For dynamics, four of our six participants categorized the visualizations as helpful. The means of their ratings for the visualization-only and both-together conditions were not statistically different but were statistically different from the audio-only treatment, indicating a dominance of the visualizations when presented together with audio. Moreover, the ratings of dynamics under the visualization-only condition were significantly more consistent than the other conditions.

    Full Text Available Verbal repetition is a fundamental language capacity where listening and speaking are inextricably coupled with each other. We have recently reported that the left inferior frontal gyrus (IFG harbors articulation-based codes, as evidenced by activation during repetition of meaningless speech sounds, i.e., pseudowords. In this study, we aimed at confirming this finding and further investigating the possibility that sound perception as well as articulation is subserved by neural circuits in this region. Using functional near-infrared spectroscopy (fNIRS, we monitored changes of hemoglobin (Hb concentration at IFG bilaterally, while subjects verbally repeated pseudowords and words. The results revealed that the proportion of oxygenated hemoglobin (O2Hb over total Hb was significantly higher at the left IFG during repetition of pseudowords than that of words, replicating the observation by functional MRI and indicating that the region processes articulatory codes for verbal repetition. More importantly for this study, hemodynamic modulations were observed at both IFG during passive listening without repetition to various sounds, including natural environmental sounds, animal vocalizations, and human nonspeech sounds. Furthermore, the O2Hb concentration increased at the left IFG but decreased at the right IFG for both speech and non-speech sounds. These findings suggest that both speech and non-speech sounds may be processed and maintained by a neural mechanism for sensorimotor integration using articulatory codes at the left IFG.

  5. Detecting self-produced speech errors before and after articulation: An ERP investigation

    Full Text Available It has been argued that speech production errors are monitored by the same neural system involved in monitoring other types of action errors. Behavioral evidence has shown that speech errors can be detected and corrected prior to articulation, yet the neural basis for such pre-articulatory speech error monitoring is poorly understood. The current study investigated speech error monitoring using a phoneme-substitution task known to elicit speech errors. Stimulus-locked event-related potential (ERP analyses comparing correct and incorrect utterances were used to assess pre-articulatory error monitoring and response-locked ERP analyses were used to assess post-articulatory monitoring. Our novel finding in the stimulus-locked analysis revealed that words that ultimately led to a speech error were associated with a larger P2 component at midline sites (FCz, Cz, and CPz. This early positivity may reflect the detection of an error in speech formulation, or a predictive mechanism to signal the potential for an upcoming speech error. The data also revealed that general conflict monitoring mechanisms are involved during this task as both correct and incorrect responses elicited an anterior N2 component typically associated with conflict monitoring. The response-locked analyses corroborated previous observations that self-produced speech errors led to a fronto-central ERN. These results demonstrate that speech errors can be detected prior to articulation, and that speech error monitoring relies on a central error monitoring mechanism.

  6. Articulated inspection arm for ITER, a demonstration in the Tore Supra tokamak

    International Nuclear Information System (INIS)

    The aim of this program is to demonstrate for ITER the feasibility of an in-vessel remote handling inspection using a long reach, limited payload carrier (1 to 10 kg) for penetration of the ITER chamber through the openings. This device is dedicated to close inspection of the Plasma Facing Components (PFC). An articulated demonstrator called articulated inspection arm (AIA) has been manufactured. A feasibility study of a full AIA operation in Tore Supra was performed, taking into account ITER reference requirements. A scale one demonstration of the AIA under ITER relevant condition is feasible on Tore Supra and would give significant improvement in research results for ITER remote Handling equipment. The test of the AIA demonstrator behaviour is foreseen in 2005 in real Tokamak conditions. The paper presents the full robot concept, the results of the first test campaign, the AIA new design and its integration on Tore Supra. Several potential uses of the AIA for the in vessel components inspection are being studied such as PFC visual inspection, water loop leak testing, laser ablation for wall detritiation and carbon dust and flakes removal are foreseen as utilities to be placed at the AIA head. These various systems are described in the paper

  7. Hybrid Bounding Volume Hierarchy Tree (HBVHT Algorithm for Collision Detection of Articulated Model Robot

    Full Text Available To reduce time for collision detection among articulated models, the collision detection algorithm of Hybrid Bounding Volume Hierarchy Tree (HBVHT was proposed to accelerate the speed of culling away triangles. The HBVHT was composed of two phases: A broad phase and a narrow phase. The broad phase consisted of Axis-Aligned Bounding Box (AABB and the Bounding Volume (BV was used to build a Multi-Level Hierarchy Tree (MLHT; the narrow phase was made up of the Oriented Bounding Box (OBB hierarchy trees and triangles. Furthermore, according to the characteristic of hierarchical structure of the HBVHT, an improved cost function was given to analyze the performance of the HBVHT. Experiments were performed between two 6-DOF robots under the Open GL environment. Two robots with the same number of triangles moved with the same trajectory for the collision experiments. Experimental results show that the efficiency of HBVHT algorithm is higher than that of the RAPID and the other two HBVHTs with different structure. The results indicate that the HBVHT algorithm can effectively improve the efficiency of collision detection among the articulated model robots.

    Introduction Dynamic MRI analysis of phonation has gathered interest in voice and speech physiology. However, there are limited data addressing the extent to which articulation is dependent on loudness. Material and Methods 12 professional singer subjects of different voice classifications were analysed concerning the vocal tract profiles recorded with dynamic real-time MRI with 25fps in different pitch and loudness conditions. The subjects were asked to sing ascending scales on the vowel /a/ in three loudness conditions (comfortable = mf, very soft = pp, very loud = ff, respectively). Furthermore, fundamental frequency and sound pressure level were analysed from the simultaneously recorded optical audio signal after noise cancellation. Results The data show articulatory differences with respect to changes of both pitch and loudness. Here, lip opening and pharynx width were increased. While the vertical larynx position was rising with pitch it was lower for greater loudness. Especially, the lip opening and pharynx width were more strongly correlated with the sound pressure level than with pitch. Conclusion For the vowel /a/ loudness has an effect on articulation during singing which should be considered when articulatory vocal tract data are interpreted. PMID:27096935

  9. Articulated Palaeozoic fossil with 17 plates greatly expands disparity of early chitons.

    2004-05-20

    Modern chitons (Mollusca: Polyplacophora) possess a highly conserved skeleton of eight shell plates (valves) surrounded by spicules or scales, and fossil evidence suggests that the chiton skeleton has changed little since the first appearance of the class in the Late Cambrian period (about 500 million years before present, Myr bp). However, the Palaeozoic problematic taxon Multiplacophora, in spite of having a more complex skeleton, shares several derived characters with chitons. The enigmatic status of the Multiplacophora is due in part to the fact that its members had an exoskeleton of numerous calcium carbonate valves that usually separated after death. A new articulated specimen from the Carboniferous period (about 335 Myr bp) of Indiana reveals that multiplacophorans had a dorsal protective surface composed of head and tail valves, left and right columns of overlapping valves (five on each side), and a central zone of five smaller valves, all surrounded by an annulus of large spines. Here we describe and name the articulated specimen and present evidence that multiplacophorans were chitons. Thus the highly conserved body plan of living chitons belies the broad disparity of this clade during the Palaeozoic era. PMID:15152250

  10. Depth effect on lightness revisited: The role of articulation, proximity and fields of illumination.

    Radonjić, Ana; Gilchrist, Alan L

    2013-01-01

    The coplanar ratio principle proposes that when the luminance range in an image is larger than the canonical reflectance range of 30:1, the lightness of a target surface depends on the luminance ratio between that target and its adjacent coplanar neighbor (Gilchrist, 1980). This conclusion is based on experiments in which changes in the perceived target depth produced large changes in its perceived lightness without significantly altering the observers' retinal image. Using the same paradigm, we explored how this depth effect on lightness depends on display complexity (articulation), proximity of the target to its highest coplanar luminance and spatial distribution of fields of illumination. Importantly, our experiments allowed us to test differing predictions made by the anchoring theory (Gilchrist et al., 1999), the coplanar ratio principle, as well as other models. We report three main findings, generally consistent with anchoring theory predictions: (1) Articulation can substantially increase the depth effect. (2) Target lightness depends not on the adjacent luminance but on the highest coplanar luminance, irrespective of its position relative to the target. (3) When a plane contains multiple fields of illumination, target lightness depends on the highest luminance in its field of illumination, not on the highest coplanar luminance. PMID:24349701

    2011-01-01

    Full Text Available Background : Standard treatment of chronic infected total knee arthroplasty (TKA is a two-stage revision, the first step being placement of an antibiotic-impregnated cement spacer. Here we describe the results of a new technique (modification of the Goldstien′s technique for intraoperative manufacture of a customized articulating spacer at minimal cost and with relatively good conformity and longevity. Materials and Methods : Thirty-six infected knees underwent this procedure from June 2002 to May 2007. The technique consists of using the freshened femur and tibia interface as molds wrapped in a tin foil for manufacturing the two components of the spacer with antibiotic-impregnated methyl methycrylate cement. We used the spacer and the femoral component of the trial set of a TKA system to mold them to perfect articulation. We also reinforced the spacer with a K-wire scaffold to prevent fracture of the cement mantle in the last 21 cases. Results : All 36 knees showed excellent results in terms of infection control, mobility, and stability. There was significant improvement in the WOMAC and Knee Society Scores (20 and 39 points respectively. There were two fractures of the spacers in the initial 15 cases that did not have K-wire scaffolding but none in the last 21 that had reinforcement. Conclusion : This technique provides a more conforming spacer, with good range of motion and stability. The reinforcement helps in preventing the fracture of the cement mantle and is cost effective.

  12. Desi Films: Articulating Images of South Asian Identity in a Global Communication Environment

    Directory of Open Access Journals (Sweden)

    Rekha Sharma

    2011-01-01

    Full Text Available Although India itself has been an important source of information about the Indian identity for Western audiences, a specialized genre of desi media have also garnered more recognition in recent years. Desi films—movies created by and/or for South Asian immigrants—are capable of reaching large numbers of people regardless of their educational level, economic status, or linguistic proficiency. Most are produced in English or with English subtitles and are easily accessible in most areas, either in theatres, video rental stores, libraries, or via Internet movie sites. This paper examines Indian diasporic films as a vehicle for cultural articulation and debate. First, it provides a theoretical foundation of hegemony and resistance with regard to notions of ethnicity and immigrants’ articulations of identity in interstitial zones. Second, it discusses sources of hegemony from Indian and Western media. Third, it explores the creation of a hybrid identity as reflected in Indian diasporic films, pointing out some of the themes and conventions of this emerging genre.

    Holzrichter, J.F.

    2000-09-15

    Very low power, GHz frequency, ''radar-like'' sensors can measure a variety of motions produced by a human user of machine interface devices. These data can be obtained ''at a distance'' and can measure ''hidden'' structures. Measurements range from acoustic induced 10-micron amplitude vibrations of vocal tract tissues, to few centimeter human speech articulator motions, to meter-class motions of the head, hands, or entire body. These EM sensors measure ''fringe motions' as reflected EM waves are mixed with a local (homodyne) reference wave. These data, when processed using models of the system being measured, provide real time states of interface positions vs. time. An example is speech articulator positions vs. time in the user's body. This information appears to be useful for a surprisingly wide range of applications ranging from speech coding and recognition, speaker or object identification, noise cancellation, hand or head motions for cursor direction, and other applications.

  15. Long-Range Motion Trajectories Extraction of Articulated Human Using Mesh Evolution

    Wu, Yuanyuan; He, Xiaohai; Kang, Byeongkeun; Song, Haiying; Nguyen, Truong Q.

    2016-04-01

    This letter presents a novel approach to extract reliable dense and long-range motion trajectories of articulated human in a video sequence. Compared with existing approaches that emphasize temporal consistency of each tracked point, we also consider the spatial structure of tracked points on the articulated human. We treat points as a set of vertices, and build a triangle mesh to join them in image space. The problem of extracting long-range motion trajectories is changed to the issue of consistency of mesh evolution over time. First, self-occlusion is detected by a novel mesh-based method and an adaptive motion estimation method is proposed to initialize mesh between successive frames. Furthermore, we propose an iterative algorithm to efficiently adjust vertices of mesh for a physically plausible deformation, which can meet the local rigidity of mesh and silhouette constraints. Finally, we compare the proposed method with the state-of-the-art methods on a set of challenging sequences. Evaluations demonstrate that our method achieves favorable performance in terms of both accuracy and integrity of extracted trajectories.

  16. The NET articulated boom: Preliminary investigations and justification for a full scale prototype

    International Nuclear Information System (INIS)

    The articulated boom system is the favourite in-vessel handling system for NET which will be used to maintain or replace in-vessel components during short term interventions. The testbed EDITH is the prototype of this system and is the logical step between the proof of principle of the system, which is already performed by the JET articulated boom, and the operational equipment for NET. EDITH is required to demonstrate that maintenance of plasma facing components can be carried out with the anticipated reliability and time. To achieve this aim EDITH is based on the experience of the JET boom and will be constructed in full scale, supplemented by a full scale mock-up. A further goal of EDITH is to allow the testing of boom components and subassemblies. The results of preliminary investigations for the boom are summarized, the need of the testbed EDITH and a full scale mock-up is discussed and both EDITH and the mock-up are described. (orig.)

  4. A computed torque method based attitude control with optimal force distribution for articulated body mobile robots

    International Nuclear Information System (INIS)

    This paper introduces an attitude control scheme based in optimal force distribution using quadratic programming which minimizes joint energy consumption. This method shares similarities with force distribution for multifingered hands, multiple coordinated manipulators and legged walking robots. In particular, an attitude control scheme was introduced inside the force distribution problem, and successfully implemented for control of the articulated body mobile robot KR-II. This is an actual mobile robot composed of cylindrical segments linked in series by prismatic joints and has a long snake-like appearance. These prismatic joints are force controlled so that each segment's vertical motion can automatically follow the terrain irregularities. An attitude control is necessary because this system acts like a system of wheeled inverted pendulum carts connected in series, being unstable by nature. The validity and effectiveness of the proposed method is verified by computer simulation and experiments with the robot KR-II. (author)

    2014-07-01

    In the creative industries, the length of time between the ideation stage and the making of physical objects is decreasing due to the use of CAD/CAM systems and adicitive manufacturing. Natural anisotropic materials, such as solid wood can also be transformed using CAD/CAM systems, but only with subtractive processes such as machining with CNC routers. Whilst some 3 axis CNC routing machines are affordable to buy and widely available, more flexible 5 axis routing machines still present themselves as a too big investment for small companies. Small refurbished articulated robots can be a cheaper alternative but they require a light end-effector. This paper presents a new lightweight tool changer that converts a small 3kg payload 6 DOF robot into a robot apprentice able to machine wood and similar soft materials.

    2004-10-01

    The present study deals with a right-handed female polyglot suffering from a Foreign Accent Syndrome (FAS) which affects her native language (L1), but not her other languages learnt since the age of 12. She had a small infarct in the left corona radiata as the result of a carotid occlusion. Her L1 was Spanish, but she also had a good command of French, English and Catalan (L2). Aphasia tests did not reveal any other significant alteration in any language. Analyses of pre-morbid and post-morbid voice recordings revealed that FAS affected Spanish dramatically, but no important changes were observed for French. Results were interpreted as showing that different brain areas control articulation of L1 and L2 learnt after a critical period. PMID:15371747

  9. Study on Roll Instability Mechanism and Stability Index of Articulated Steering Vehicles

    2016-01-01

    Full Text Available This study examines the roll instability mechanism and stability index of articulated steering vehicles (ASVs by taking wheel loaders as the research object. A seven-degree-of-freedom nonlinear dynamics model of the ASVs is built on the basis of multibody dynamics. A physical prototype model of an ASV is designed and manufactured to validate the dynamic model. Test results reasonably agree with the simulation results, which indicates that the established dynamic model can reasonably describe ASV movements. Detailed analysis of the rollover stability of the wheel loader is performed with the use of the established dynamic model. Analysis results show that rollover will occur when the roll angular velocity exceeds a critical threshold, which is affected by lateral acceleration and slope angle. On this basis, a dynamic stability index applicable to the ASVs is presented.

This research, which combines field work with a diachronicand synchronic vision and draws on comparative studies of peasanteconomies, seeks to explain the factors that facilitated this articulationin the early 1960’s. Among the factors that influenced thisprocess are the ecological advantages the community enjoyed, itsopenness to change, its relative closeness to large urban centers,the existence of roads and infrastructure, and market advantages interms of prices and the growing consumer demand for fruit.

    Pyoderma gangrenosum (PG), an extra-intestinal manifestation of ulcerative colitis (UC), is extremely rare. Up to now, there is no any data reported the occurrence of PG in joints, especially in China. The management of PG associated with UC is a therapeutic challenge. Our report here showed that a female patient diagnosed as UC complained a pustule in the dorsal side of left wrist, primarily was diagnosed as bone tuberculosis. The pustule progressed rapidly into a severe painful necrolytic cutaneous ulcer with a pale purple irregular destructive ulcer edge, this patient was diagnosed by UC complicated with PG, and skin lesions were cured by UC treatment. Here, we for the first time present a case acquired correct diagnosis and successful treatment of UC associated with PG of articulations carpi. We report this case here in order to provide more information about this disease to more doctors, furthermore, to decrease the rates of misdiagnosis and missed diagnosis. PMID:26770554

    Wiwaxia is a bizarre metazoan that has been interpreted as a primitive mollusc and as a polychaete annelid worm. Extensive material from the Burgess Shale provides a detailed picture of its morphology and ontogeny, but the fossil record outside this lagerstätte is scarce, and complete wiwaxiids are particularly rare. Here we report small articulated specimens of Wiwaxia foliosa sp. nov. from the Xiaoshiba fauna (Cambrian Stage 3, Hongjingshao Formation, Kunming, south China). Although spines are absent, the fossils' sclerites - like those of W. corrugata - are symmetrically arranged in five distinct zones. They form rows across the body, and were individually added and shed throughout growth to retain an approximately symmetrical body shape. Their development pattern suggests a molluscan affinity. The basic body plan of wiwaxiids is fundamentally conserved across two continents through Cambrian Stages 3-5 - revealing morphological stasis in the wake of the Cambrian explosion.

    Shoulder injury is one of the most severe risks that have the potential to impair crewmembers' performance and health in long duration space flight. Overall, 64% of crewmembers experience shoulder pain after extra-vehicular training in a space suit, and 14% of symptomatic crewmembers require surgical repair (Williams & Johnson, 2003). Suboptimal suit fit, in particular at the shoulder region, has been identified as one of the predominant risk factors. However, traditional suit fit assessments and laser scans represent only a single person's data, and thus may not be generalized across wide variations of body shapes and poses. The aim of this work is to develop a software tool based on a statistical analysis of a large dataset of crewmember body shapes. This tool can accurately predict the skin deformation and shape variations for any body size and shoulder pose for a target population, from which the geometry can be exported and evaluated against suit models in commercial CAD software. A preliminary software tool was developed by statistically analyzing 150 body shapes matched with body dimension ranges specified in the Human-Systems Integration Requirements of NASA ("baseline model"). Further, the baseline model was incorporated with shoulder joint articulation ("articulation model"), using additional subjects scanned in a variety of shoulder poses across a pre-specified range of motion. Scan data was cleaned and aligned using body landmarks. The skin deformation patterns were dimensionally reduced and the co-variation with shoulder angles was analyzed. A software tool is currently in development and will be presented in the final proceeding. This tool would allow suit engineers to parametrically generate body shapes in strategically targeted anthropometry dimensions and shoulder poses. This would also enable virtual fit assessments, with which the contact volume and clearance between the suit and body surface can be predictively quantified at reduced time and

    We present processing methods and visualization techniques for accurately characterizing and interpreting kinematical data of flexion-extension motion of the knee joint based on helical axes. We make use of the Lie group of rigid body motions and particularly its Lie algebra for a natural representation of motion sequences. This allows to analyze and compute the finite helical axis (FHA) and instantaneous helical axis (IHA) in a unified way without redundant degrees of freedom or singularities. A polynomial fitting based on Legendre polynomials within the Lie algebra is applied to provide a smooth description of a given discrete knee motion sequence which is essential for obtaining stable instantaneous helical axes for further analysis. Moreover, this allows for an efficient overall similarity comparison across several motion sequences in order to differentiate among several cases. Our approach combines a specifically designed patient-specific three-dimensional visualization basing on the processed helical axes information and incorporating computed tomography (CT) scans for an intuitive interpretation of the axes and their geometrical relation with respect to the knee joint anatomy. In addition, in the context of the study of diseases affecting the musculoskeletal articulation, we propose to integrate the above tools into a multiscale framework for exploring related data sets distributed across multiple spatial scales. We demonstrate the utility of our methods, exemplarily processing a collection of motion sequences acquired from experimental data involving several surgery techniques. Our approach enables an accurate analysis, visualization and comparison of knee joint articulation, contributing to the evaluation and diagnosis in medical applications. PMID:27367532

    1998-01-01

    Correct determination of the occlusal plane is one of the most difficult stages of treatment. After determining the correct occlusal plane its reproduction is possible thanks to the use of articulators. These instruments simulate movements of the jaw in three planes. One of the most optimal articulators is a semi-adjustable type. These instruments are not complicated and give good treatment results. A modern semiadjustable type of articulator is Quick Master. The face-bow which comes together with this instrument is used for recording and transferring the occlusal relation to the articulator. This allows to mount models in an adequate three dimensional position in relation to the temporo-mandibular joint. The use of these instruments leads to many questions and doubts due to difficulties in their use. Therefore the aim of my study was to elaborate a simple method of occlusal recording. I have also compared the treatment results of edentulous patients treated with the use of an articulator and the use of a traditional method. Prosthetic restorations were prepared among 60 patients. The study material was divided into two groups of 30 patients each. In the control group for preparing complete dentures the Gysi method was employed as the most common. In the study group a face-bow and articulator were used. After preparing complete dentures detailed clinical control examinations were carried out and were repeated 24-48 hours after fitting the dentures and also after 3 and 6 months of their use. Working with the face-bow I have employed my own modification of recording the occlusion. The upper wax rim was placed on a slightly warmed bite fork and drawing pins were placed in the recording block to act as a type of key. The lower rim was warmed and brought to occlusal contact a couple of times. Next the face-bow was inserted. The recorded occlusion was transferred and mounted in the articulator. Teeth in both cases were set up similarly to the Gysi method. Lower teeth

    Bipolar disorder is a recurrent chronic disorder characterised by fluctuations in mood state and energy. It affects more than 1% of the world's population irrespective of nationality, ethnic origin, or socioeconomic status. Bipolar disorder is one of the main causes of disability among young people, leading to cognitive and functional impairment and raised mortality, particularly death by suicide. A high prevalence of psychiatric and medical comorbidities is typical in affected individuals. Accurate diagnosis of bipolar disorder is difficult in clinical practice because onset is most commonly a depressive episode and looks similar to unipolar depression. Moreover, there are currently no valid biomarkers for the disorder. Therefore, the role of clinical assessment remains key. Detection of hypomanic periods and longitudinal assessment are crucial to differentiate bipolar disorder from other conditions. Current knowledge of the evolving pharmacological and psychological strategies in bipolar disorder is of utmost importance. PMID:26388529

  2. The nature of psychiatric disorders.

    Kendler, Kenneth S

    2016-02-01

    A foundational question for the discipline of psychiatry is the nature of psychiatric disorders. What kinds of things are they? In this paper, I review and critique three major relevant theories: realism, pragmatism and constructivism. Realism assumes that the content of science is real and independent of human activities. I distinguish two "flavors" of realism: chemistry-based, for which the paradigmatic example is elements of the periodic table, and biology-based, for which the paradigm is species. The latter is a much better fit for psychiatry. Pragmatism articulates a sensible approach to psychiatric disorders just seeking categories that perform well in the world. But it makes no claim about the reality of those disorders. This is problematic, because we have a duty to advocate for our profession and our patients against other physicians who never doubt the reality of the disorders they treat. Constructivism has been associated with anti-psychiatry activists, but we should admit that social forces play a role in the creation of our diagnoses, as they do in many sciences. However, truly socially constructed psychiatric disorders are rare. I then describe powerful arguments against a realist theory of psychiatric disorders. Because so many prior psychiatric diagnoses have been proposed and then abandoned, can we really claim that our current nosologies have it right? Much of our current nosology arose from a series of historical figures and events which could have gone differently. If we re-run the tape of history over and over again, the DSM and ICD would not likely have the same categories on every iteration. Therefore, we should argue more confidently for the reality of broader constructs of psychiatric illness rather than our current diagnostic categories, which remain tentative. Finally, instead of thinking that our disorders are true because they correspond to clear entities in the world, we should consider a coherence theory of truth by which disorders

    Full Text Available ABSTRACT Speech disorders are common manifestations of Parkinson´s disease. Objective To compare speech articulation in patients according to age at onset of the disease. Methods Fifty patients was divided into two groups: Group I consisted of 30 patients with age at onset between 40 and 55 years; Group II consisted of 20 patients with age at onset after 65 years. All patients were evaluated based on the Unified Parkinson’s Disease Rating Scale scores, Hoehn and Yahr scale and speech evaluation by perceptual and acoustical analysis. Results There was no statistically significant difference between the two groups regarding neurological involvement and speech characteristics. Correlation analysis indicated differences in speech articulation in relation to staging and axial scores of rigidity and bradykinesia for middle and late-onset. Conclusions Impairment of speech articulation did not correlate with age at onset of disease, but was positively related with disease duration and higher scores in both groups.

    A complete neurobiological understanding of speech motor control requires determination of the relationship between simultaneously recorded neural activity and the kinematics of the lips, jaw, tongue, and larynx. Many speech articulators are internal to the vocal tract, and therefore simultaneously tracking the kinematics of all articulators is nontrivial—especially in the context of human electrophysiology recordings. Here, we describe a noninvasive, multi-modal imaging system to monitor vocal tract kinematics, demonstrate this system in six speakers during production of nine American English vowels, and provide new analysis of such data. Classification and regression analysis revealed considerable variability in the articulator-to-acoustic relationship across speakers. Non-negative matrix factorization extracted basis sets capturing vocal tract shapes allowing for higher vowel classification accuracy than traditional methods. Statistical speech synthesis generated speech from vocal tract measurements, and we demonstrate perceptual identification. We demonstrate the capacity to predict lip kinematics from ventral sensorimotor cortical activity. These results demonstrate a multi-modal system to non-invasively monitor articulator kinematics during speech production, describe novel analytic methods for relating kinematic data to speech acoustics, and provide the first decoding of speech kinematics from electrocorticography. These advances will be critical for understanding the cortical basis of speech production and the creation of vocal prosthetics. PMID:27019106

    Eating disorders are characterized by aberrant patterns of eating behavior, including such symptoms as extreme restriction of food intake or binge eating, and severe disturbances in the perception of body shape and weight, as well as a drive for thinness and obsessive fears of becoming fat. Eating disorder is an important cause for physical and psychosocial morbidity in young women. Patients with eating disorders have a deficit in the cognitive process and functional abnormalities in the brain system. Recently, brain-imaging techniques have been used to identify specific brain areas that function abnormally in patients with eating disorders. We have discussed the clinical and cognitive aspects of eating disorders and summarized neuroimaging studies of eating disorders. PMID:25681363

  18. Using articulation and inscription as catalysts for reflection: Design principles for reflective inquiry

    Science.gov (United States)

    Loh, Ben Tun-Bin

    2003-07-01

    The demand for students to engage in complex student-driven and information-rich inquiry investigations poses challenges to existing learning environments. Students are not familiar with this style of work, and lack the skills, tools, and expectations it demands, often forging blindly forward in the investigation. If students are to be successful, they need to learn to be reflective inquirers, periodically stepping back from an investigation to evaluate their work. The fundamental goal of my dissertation is to understand how to design learning environments to promote and support reflective inquiry. I have three basic research questions: how to define this mode of work, how to help students learn it, and understanding how it facilitates reflection when enacted in a classroom. I take an exploratory approach in which, through iterative cycles of design, development, and reflection, I develop principles of design for reflective inquiry, instantiate those principles in the design of a software environment, and test that software in the context of classroom work. My work contributes to the understanding of reflective inquiry in three ways: First, I define a task model that describes the kinds of operations (cognitive tasks) that students should engage in as reflective inquirers. These operations are defined in terms of two basic tasks: articulation and inscription, which serve as catalysts for externalizing student thinking as objects of and triggers for reflection. Second, I instantiate the task model in the design of software tools (the Progress Portfolio). And, through proof of concept pilot studies, I examine how the task model and tools helped students with their investigative classroom work. Finally, I take a step back from these implementations and articulate general design principles for reflective inquiry with the goal of informing the design of other reflective inquiry learning environments. There are three design principles: (1) Provide a designated work space

    2007-01-01

    The experiment system of 1000 m deep sea mining system is built up with the similarity theory. Sine mechanism is used to simulate mining ship to generate lateral shock excitation by ocean wave. Simulation and experiment of spherical joint connecting deep sea mining system has been done in band six marine conditions. The results indicate that the moment of spherical joint connecting deep sea mining is smaller than that of the thread connected ones, the lifting pipe of spherical joint is "flexible pipe". The flexural torque of the articulated lifting pipe system in pump and buffer is generally periodic variation with some irregularity, the value is stable on 60 N·S, and it is obviously smaller than that of the fixed lifting pipe system; The total displacement exhibits cyclic variation pattern, and the periodicity of them is longer than that of sea current. The results of experiment and simulation are basically consistent. And the analysis in the paper offers theoretical foundation of 1000 m deep sea mining system in China.

  1. Design and characterization of a multi-articulated robotic bat wing

    International Nuclear Information System (INIS)

    There are many challenges to measuring power input and force output from a flapping vertebrate. Animals can vary a multitude of kinematic parameters simultaneously, and methods for measuring power and force are either not possible in a flying vertebrate or are very time and equipment intensive. To circumvent these challenges, we constructed a robotic, multi-articulated bat wing that allows us to measure power input and force output simultaneously, across a range of kinematic parameters. The robot is modeled after the lesser dog-faced fruit bat, Cynopterus brachyotis, and contains seven joints powered by three servo motors. Collectively, this joint and motor arrangement allows the robot to vary wingbeat frequency, wingbeat amplitude, stroke plane, downstroke ratio, and wing folding. We describe the design, construction, programing, instrumentation, characterization, and analysis of the robot. We show that the kinematics, inputs, and outputs demonstrate good repeatability both within and among trials. Finally, we describe lessons about the structure of living bats learned from trying to mimic their flight in a robotic wing. (paper)

    2015-01-01

    The present approach exploits the biomechanical connection between articulation and ingestion-related mouth movements to introduce a novel psychological principle of brand name design. We constructed brand names for diverse products with consonantal stricture spots either from the front to the rear of the mouth, thus inwards (e.g., BODIKA), or from the rear to the front, thus outwards (e.g., KODIBA). These muscle dynamics resemble the oral kinematics during either ingestion (inwards), which feels positive, or expectoration (outwards), which feels negative. In 7 experiments (total N = 1261), participants liked products with inward names more than products with outward names (Experiment 1), reported higher purchase intentions (Experiment 2), and higher willingness-to-pay (Experiments 3a-3c, 4, 5), with the price gain amounting to 4-13% of the average estimated product value. These effects occurred across English and German language, under silent reading, for both edible and non-edible products, and even in the presence of a much stronger price determinant, namely fair-trade production (Experiment 5).

  3. Development of a long reach articulated manipulator for ITER in vessel inspection under vacuum and temperature

    International Nuclear Information System (INIS)

    This project takes place in the EFDA Remote Handling (RH) activities for the fusion reactor International Thermonuclear Experimental Reactor (ITER). The aim of the R and D program is to demonstrate the feasibility of in-vessel RH intervention by a long reach, limited payload manipulator which penetrates the first wall using the six IVVS penetrations. Potential activities for this device include close inspection of the plasma facing surfaces and leak detection. The work includes the design, manufacture and testing of a demonstrator articulated manipulator called the In-Vessel Penetrator (IVP). The first part of this work concerned the analysis of the requirements and resulted in the development of the conceptual design of the overall manipulator, comprising a 5 module, 11 d.o.f robot based on a parallelogram structure. A scale one mock up of a representative segment was manufactured and tested. In parallel, a feasibility study of the IVP operation was made and provided recommendations to modify the design for intervention under vacuum and temperature. Some technologies were selected and analysed to determine their suitability to the IVP application and items identified for further validation. This paper presents the whole robot concept, the results of the test campaign on the prototype demonstrator and the vacuum and temperature technologies study

  4. Robust intelligent sliding model control using recurrent cerebellar model articulation controller for uncertain nonlinear chaotic systems

    International Nuclear Information System (INIS)

    In this paper, a robust intelligent sliding model control (RISMC) scheme using an adaptive recurrent cerebellar model articulation controller (RCMAC) is developed for a class of uncertain nonlinear chaotic systems. This RISMC system offers a design approach to drive the state trajectory to track a desired trajectory, and it is comprised of an adaptive RCMAC and a robust controller. The adaptive RCMAC is used to mimic an ideal sliding mode control (SMC) due to unknown system dynamics, and a robust controller is designed to recover the residual approximation error for guaranteeing the stable characteristic. Moreover, the Taylor linearization technique is employed to derive the linearized model of the RCMAC. The all adaptation laws of the RISMC system are derived based on the Lyapunov stability analysis and projection algorithm, so that the stability of the system can be guaranteed. Finally, the proposed RISMC system is applied to control a Van der Pol oscillator, a Genesio chaotic system and a Chua's chaotic circuit. The effectiveness of the proposed control scheme is verified by some simulation results with unknown system dynamics and existence of external disturbance. In addition, the advantages of the proposed RISMC are indicated in comparison with a SMC system

In case of the in-vessel maintenance using a flexible manipulator, it is quite essential to develop an autonomous control method for compensating a deflection of manipulator so as to minimize the maintenance time with high precision. For this purpose, a new position control method using a combination of neural network predictor with a rigid inverse kinematics is being developed. The key features of this method are to simplify a kinematics modeling of flexible manipulator, to enable quick position compensation in stead of ordinary large matrix compensation, and to be applicable to a wide variety of manipulator characteristics. A sub-scaled model of flexible manipulator with 4 joints has been fabricated for a benchmark experiments of the autonomous position control. Comparing analytical simulation with experiments using the flexible manipulator, it has been demonstrated that the new position control method gives significant improvement in control performance with high precision in order of a figure. In addition, further optimization can be possible by adding other non-linear predictors such as radial basis function and fuzzy modeling. This paper describes the details of a sub-scaled flexible manipulator and a neural network position control system as well as results of analytical simulation and benchmark experiments. (author)

  6. Little value creation, articulation and propagating forces: A hypothesis for the Mexican manufacturing sector

    Directory of Open Access Journals (Sweden)

    Santiago Roca T

    2015-12-01

    Full Text Available This paper evaluates the impact of Mexican trade and productive integration processes during the last 20 years. It finds evidence that growing per capita income in Mexico is directly related to its “trade opening”, but is inversely related to the growth of its manufacturing export industry. Specifically, for each point of growth in “trade opening” (as a proportion of GDP per capita income grew by 0.22%; while each point of increase in the share of industrial exports reduced income per person by 0.09%. To explain this apparent contradiction between the positive effect of “trade opening” and the negative impact of productive manufacturing specialization, we examined the characteristics of Mexico's industry. Results show that although Mexico's export-led industrialization successfully adapted to the world market and transformed its productive, business, organizational and technological structure, it did not translate into adequate macroeconomic benefits due to the absence of strong value dissemination forces over the rest of the economy. In this sense, poor internal linkages in the maquila industry, its high propensity to import, and its limited value added generation, among other elements, led the Mexican industry to operate as an export enclave. In those circumstances, manufacturing does not generates positive externalities nor articulations, nor strong disseminations that increase and multiplies value in other sectors of industry, thus limiting expansion effects and restraining or even reducing-under some specific circumstances-per capita income growth.

  7. A New Flatness Pattern Recognition Model Based on Cerebellar Model Articulation Controllers Network

    2008-01-01

    In the traditional flatness pattern recognition neural network,the topologic configurations need to be rebuilt with a changing width of cold strip.Furthermore,the large learning assignment,slow convergence,and local minimum in the network are observed.Moreover,going by the structure of the tradtional neural network,according to experience,the model is time-consuming and complex.Thus,a new approach of flatness pattern recognition is proposed based on the CMAC (cerebellar model articulation controllers) neural network.The difference in fuzzy distances between samples and the basic patterns is introduced as the input of the CMAC network.Simultaneously,the adequate learning rate is improved in the error correction algorithm of this neural network.The new approach with advantages,such as high learning speed,good generalization,and easy implementation,is efficient and intelligent.The simulation results show that the speed and accuracy of the flatness pattern recognition model are obviously improved.

  8. Seeing double, thinking twice: the Toronto drag kings and (re-) articulations of masculinity.

    Science.gov (United States)

    Noble, Jean Bobby

    2002-01-01

    Through a close reading of the performances of masculinity by the Toronto drag kings, this chapter argues that drag king shows parody the hyper-masculine star at his most contradictory and dialogic. Given that drag king performances parody both the contradictions of masculinity on stage, and the productive technologies of the star, king performances are essentially both meta-theatrical (performances about performing where lights, music, body language, dance all make the man) and meta-performative (performances which are at once conditioned by the performative reiterations which enable a fiction of identity in the first place). Finally, I explore the rather abstracted question of what cultural work the category of "drag king" does. I argue that it is a term which articulates a series of productive but necessary slippages in and through the contradictory and dialogic practices of identification. The bottom line is this: drag kings are situated in and play with the ironic no man's land between "lesbian," "butch," "transman" and "bio-boy" where the sell evident is neither. PMID:12769283

    2012-01-01

    In this paper we present the first algorithm in the streaming model to characterize completely the biconnectivity properties of undirected networks: articulation points, bridges, and connected and biconnected components. The motivation of our work was the development of a real-time algorithm to monitor the connectivity of the Autonomous Systems (AS) Network, but the solution provided is general enough to be applied to any network. The network structure is represented by a graph, and the algorithm is analyzed in the datastream framework. Here, as in the \\emph{on-line} model, the input graph is revealed one item (i.e., graph edge) after the other, in an on-line fashion; but, if compared to traditional on-line computation, there are stricter requirements for both memory occupation and per item processing time. Our algorithm works by properly updating a forest over the graph nodes. All the graph (bi)connectivity properties are stored in this forest. We prove the correctness of the algorithm, together with its spa...

    Data regarding in vivo performance of titanium nitride (TiN) coated prosthetic femoral heads is scarce, and available studies of older generations of implants demonstrated coating wear in vivo. That is why we conducted a retrieval analysis of 11 femoral heads (articulating in vivo for 1-56 months) with TiN film formed using physical vapor deposition (PVD), to verify if coating failure is a problem in contemporary implants. Retrieved implants were examined using scanning electron microscope, coating roughness was evaluated with a contact profilometer and adhesion was tested using a Rockwell HRC test according to VDI 3824 guideline. Although no gross failure of the TiN coating was observed in our retrievals, all implants had defects typical for PVD coatings, such as pinholes, small titanium droplets and blisters with delaminated coating. In some heads the coating was contaminated with small niobium (Nb) droplets uniformly scattered on the entire surface of the film. Presence of Nb contamination was associated with an increased number and area of other types of defects and poorer coating adhesion. In one component, subjected to multiple dislocations we found severe delamination and cracking of the coating, increased roughness and the presence of third bodies. Our results indicate, that although wear of the coating is lower than seen in older generations of implants, inconsistent quality of the TiN film among different implants indicates the need for strict monitoring of the manufacturing process.

    2014-12-01

    Articulated Arm Coordinate Measuring Machines (AACMMs) have gradually evolved and are increasingly used in mechanical industry. At present, measurement uncertainties relating to the use of these devices are not yet well quantified. The work carried out consists of determining the measurement uncertainties of a mechanical part by an AACMM. The studies aiming to develop a model of measurement uncertainty are based on the Monte Carlo method developed in Supplement 1 of the Guide to Expression of Uncertainty in Measurement [1] but also identifying and characterizing the main sources of uncertainty. A multi-level Monte Carlo approach principle has been developed which allows for characterizing the possible evolution of the AACMM during the measurement and quantifying in a second level the uncertainty on the considered measurand. The first Monte Carlo level is the most complex and is thus divided into three sub-levels, namely characterization on the positioning error of a point, estimation of calibration errors and evaluation of fluctuations of the ‘localization point’. The global method is thus presented and results of the first sub-level are particularly developed. The main sources of uncertainty, including AACMM deformations, are exposed.

    2013-05-01

    Full Text Available The articulated arm coordinate measuring machine (AACMM is a kind of new coordinate measuring device based on non-Cartesian system. The measuring accuracy of the AACMM can be effectively improved by parameter identification. However, some of the structural parameters are coupling (linearly related, so the structural parameters usually cannot be identified correctly. The Jacobian matrix was obtained through differential transformation of the kinematic model of a 6-DOF AACMM. The rank calculation results show that the Jacobian matrix is not full rank, which means some structural parameters are linearly related. Singular value decomposition and the elementary row transform of the Jacobian matrix were carried out to determine the linearly related structural parameters. And two pairs of structural parameters were found to be linearly related, which can’t be identified at the same time. Finally, the linear correlation was applied in the structural parameters identification, and the results show that the linear correlation can make the identification obtain correct structural parameters.

  13. Reframing and Articulating Socio-scientific Classroom Discourses on Genetic Testing from an STS Perspective

    Science.gov (United States)

    Boerwinkel, Dirk Jan; Swierstra, Tsjalling; Waarlo, Arend Jan

    2012-08-01

    In recent decades, Science & Technology Studies (STS) have revealed the dynamic interaction between science and technology and society. Technology development is not an autonomous process and its artifacts are not socially inert. Society and technology shape each other. Technologies often have `soft impacts' in terms of unpredicted side effects on individuals and society. Nevertheless, current societal discourse on technological innovations is still dominated by `hard impacts' such as quantifiable risks for health, safety and the environment. Furthermore, participants in socio-scientific discourses often underestimate their agency in influencing technological innovations, and at the same time overestimate their freedom of choice to use a technology. Past debates on technological innovations have shown how these debates were framed and often caught in fruitless discourse patterns or arguments. Interventionist STS research experiments with solutions to this problem. Assuming that an STS perspective is helpful in reframing and articulating socio-scientific classroom discourses, the case of genetic testing is used to explore this. An important positive `hard impact' of genetic testing is disease prevention. However, this is put into perspective by addressing `soft impacts' such as limited access to certain careers based on genetic risk and changes in the conception of health and the perception of responsibility for one's health. Discussion stoppers such as `playing God' or `We can't stop technological advancement' can be challenged through uncovering underlying assumptions. The use of narratives and future scenarios in classrooms seems fruitful in provoking imagination and engaging students in public debates on technological innovations.

    Batchelor, E S

    1989-01-01

    The arithmetic learning disability literature was reviewed and critiqued. Due to the paucity of research in this area, few conclusions may be inferred. In general, the available research has provided tentative hypotheses about the nature of arithmetic disabilities. A variety of psychosocial variables notwithstanding, childhood arithmetic disability may directly result from cerebral dysfunction, poor motivation, and emotional/behavioral disturbance. However, further research is necessary in order to clarify the effects of maturation on arithmetic skills acquisition. Indeed, one approach to identification of the disorder would consider individual differences in neuropsychological development and performance affecting arithmetic achievement. It was concluded that a more comprehensive approach to investigating and diagnosing childhood arithmetic disability is needed. Reformulations and methods of study were articulated. Six related lines of research were outlined. A diagnostic rating scale was suggested which would account for type and severity of disorder. Diagnostic criteria were recommended based on the degree and definition of disability. Needs for remediation research were briefly explored. PMID:2485827

  1. Contribution to the automatic command in robotics - Application to the command by microprocessors of the articulated systems

    International Nuclear Information System (INIS)

    The first part of the present paper deals with the main methods of changing the coordinates for a general articulated system. After a definition of the coordinates changing, we propose a coordination system designed for easy programming of the movements. Its characteristic is to permit the action anywhere on the manipulated object. The second part deals with the force regulation problem. For this purpose we have developed a general force sensor. The informations delivered by the sensor are used by force regulators which are intended for the automatic assembly of subsystems. In the third part the dynamic problem of the articulated systems is exposed. We present a new method which allows to determine dynamic parameters from appropriate motions of the robot. These parameters are then used to implement the dynamic control. Several applications, using the powerful microprocessor INTEL 8086 and its arithmetic coprocessor 8087, are presented, in order to demonstrate the performances gained. (author)

    Full Text Available Background and Aim: Speech as a motor phenomenon requires repetitive and rapid function of articulatory organs performing extremely fine movements. Practice on motor skills results in facilitation in treatment progress of children with phonological disorders. The purpose of this study was to compare motor skills in 5-year-old children with phonological and phonetic disorders.Methods: Thirty-two children age 5 years, 16 with phonemical speech sound disorders and 16 with difficulty at a phonetic level participated in this study. TOLD Test was performed for linguistic skills investigation among children. Phonetic test, Wepman test, diadochokinesis and oral assessment was used for diagnosis between phonological and phonetic disorders. The children were also evaluated with Oseretsky motor developmental scale .Results: In comparison, mean scores of movement skills between both groups showed significant difference (p=0.006 and children with phonetic disorder got significantly higher scores on all part of this test.Conclusions: The findings of this study support the idea that speech sound disorders are frequently associated with motor problems, and that type of articulation disorder affects the motor performance in a different way. Phonological disorders seem to have more impact on motor performance than phonetic disorders. The results authenticate the need to pay more attention to the motor skills of children with articulation disorders.

  10. Design optimization of an articulated boom for NET in-vessel handling unit

    International Nuclear Information System (INIS)

    In-vessel components of fusion reactors must be remotely replaceable. The necessary handling will be performed from inside the torus by means of work units. A major problem is to carry the work units inside the torus. One concept to solve this problem is to use an in-vessel handling unit based on an articulated boom. It is supported outside the torus and enters the torus through an entry port. Additional supports are not available. Then the work unit (manipulator unit, diverter handling unit or antenna handling unit), attached to the end-frame of the boom, is able to reach any point inside the torus. Therefore the boom consists of eleven links connected by yaw joints. Its stretched (unfolded) length is about 25 m. Due to the scissor type of design, the boom can be folded such that the required area to store it is only 10.25 x 3.2 m. The cross-sections of the links (except those staying outside the torus) are 350 x 1350 mm. In order to allow easy repair and exchange, the drive mechanisms for the joints and the necessary cable are located above the links. The resulting overall dimensions are such that the boom may pass the entry port having an opening of 650 x 1900 mm. The maximum load at the tip of the boom is about 3900 kg. It consists of the maximum payload of 1000 kg (which is the load of a diverter plate plus gripper) and the load of the diverter handling unit of 29000 kg. The design of the boom such that the stresses and strains are within allowed limits turned out to be a difficult task. It led to a boom dead load of about 25000 kg which is 25-times the payload. In this paper the structural mechanics assessment to find an appropriate design is described

    2010-05-01

    Full Text Available In this paper an Articulated Entity Relationship (AER diagram is proposed, which is an extension of EntityRelationship (ER diagram to accommodate the Functional Dependency (FD information as its integral partfor complete automation of normalization. In current relational databases (RDBMS automation ofnormalization by top down approach is possible using ER diagram as an input, provided the FD informationis available independently, meanwhile, through user interaction. Such automation we call partial andconditional automation. To avoid this user interaction, there is a strong need to accommodate FDinformation as an element of ER diagram itself. Moreover, ER diagrams are not designed by taking intoaccount the requirements of normalization. However, for better automation of normalization it must be anintegral part of conceptual design (ER Diagram. The prime motivation behind this paper to design a systemthat need only proposed AER diagram as a sole input and normalize the database up to a given normal formin one go. This would allow more amount of automation than the current approach. Such automation we callas total and unconditional automation, which is better and complete in true sense. As the proposed AERdiagram is designed by taking in to account the normalization process, normalization up to Boyce CoddNormal Form (BCNF becomes an integral part of conceptual design. Additional advantage of AER diagramis that any modifications (addition, deletion or updation of attributes made to the AER diagram willautomatically be reflected in its FD information. Thus description of schema and FD information isguaranteed to be consistent. This cannot be assured in current approach using ER diagrams, as schema andFD information are provided to the system at two different times, separately.

  13. On the sway stability improvement of car-caravan systems by articulated connections

    Science.gov (United States)

    Sorge, Francesco

    2015-09-01

    The present analysis is addressed to some promising connection arrangements between the towing vehicles and the towed trailers, where the two units are linked by four-bar isosceles trapeziums in place of the conventional pintle hitch. Two types of instability, of the divergent type or the oscillating type, may be analysed by the Routh-Hurwitz criterion or by the direct analysis of the characteristic equation. The constant term of this equation vanishes at the divergent instability threshold (zero of a real root), whereas the equation splits into two lower degree algebraic 'sub-equations' when the oscillating instability arises (pair of pure imaginary roots). A large field of geometrical configurations of the four-bar linkage may be quickly tested by numerical search procedures, including those where the sidebars of the linkage converge towards the inside of the drawing car and shift the relative centre of rotation forward, and those converging backward towards the trailer. Maps of the critical velocity as a function of the geometrical or physical parameters may be easily traced. They clearly show the favourable influence of the forward four-bar connection in general and the benefits achievable comparing with the conventional coupling. Actually, it is conceivable to increase the critical speed by optimising the four-bar design depending on the weight distribution on the axles and on the other geometrical and physical properties. Moreover, this type of connection may produce significant corrections to the under-steering or over-steering conduct of the articulated vehicle. The off-tracking and the manoeuvrability along curved paths are also studied, showing the benefits or the drawbacks of the four-bar linkage for the various configurations.

    Full Text Available This paper is divided into three parts. I begin with a short history of the way American psychiatrists have defined mental disorder in general, and paraphilias (sexual perversions in particular, from the 1950s to 2013. I look at how the different editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM have articulated (or in the case of the future DSM-5, will articulate the distinction between health and disease. In the second part I suggest how psychiatrists might want to modify their approach to the definition of mental disorder. In the third part I explain why the paraphilias in particular should be removed from the current psychiatric classification of diseases.

  14. Use of articulated registration for response assessment of individual metastatic bone lesions

    International Nuclear Information System (INIS)

    Accurate skeleton registration is necessary to match corresponding metastatic bone lesions for response assessment over multiple scans. In articulated registration (ART), whole-body skeletons are registered by auto-segmenting individual bones, then rigidly aligning them. Performance and robustness of the ART in lesion matching were evaluated and compared to other commonly used registration techniques. Sixteen prostate cancer patients were treated either with molecular targeted therapy or chemotherapy. Ten out of the 16 patients underwent the double baseline whole-body [F-18]NaF PET/CT scans for test-retest (TRT) evaluation. Twelve of the 16 patients underwent pre- and mid-treatment [F-18]NaF PET/CT scans. Skeletons at different time points were registered using ART, rigid, and deformable (DR) registration algorithms. The corresponding lesions were contoured and identified on successive PET images based on including the voxels with the standardized uptake value over 15. Each algorithm was evaluated for its ability to accurately align corresponding lesions via skeleton registration. A lesion matching score (MS) was measured for each lesion, which quantified the per cent overlap between the lesion's two corresponding contours. Three separate sensitivity studies were conducted to investigate the robustness of ART in matching: sensitivity of lesion matching to various contouring threshold levels, effects of imperfections in the bone auto-segmentation and sensitivity of mis-registration. The performance of ART (MS = 82% for both datasets, p ≪ 0.001) in lesion matching was significantly better than rigid (MSTRT = 53%, MSResponse = 46%) and DR (MSTRT = 46%, MSResponse = 45%) algorithms. Neither varying threshold levels for lesion contouring nor imperfect bone segmentation had significant (p∼0.10) impact on the ART matching performance as the MS remained unchanged. Despite the mis-registration reduced MS for ART, as low as 67% (p ≪ 0.001), the performance

    Lomnitz, L

    1978-01-01

    This article utilizes field data from Mexico City squatter settlements and personal interviews with employers to analyze some aspects of social relations between the informal sector and the formal urban sector, and compares the results with findings of other anthropologists in Mexico and elsewhere to derive a series of theoretical generalizations concerning mechanisms of articulation between the marginal sector and the formal economic and political institutions of the society. The formal sector is postulated to consist of the 3 subsectors of power, capital, and labor, which are in permanent conflict among themselves but all of which enjoy labor security and an assured minimal level of income. The marginal or informal sector lacks employment security, a minimal income level, and bargaining power. It is characterized by a small scale economy utilizing intensive familial labor. The informal sector is marginal to the dominant industrial system of production and the state apparatus, although it fulfills functions in terms of the national economy. 2 types of relationships may be distinguished in the social organization of the marginal sector: reciprocal relations between equals which form a network for the exchange of goods and services, or patron/client relations which are used, for example, in the case of petty entrepreneurs utilizing their relatives and acquaintances to create units of production. The functions of reciprocal relations are affected by social, physical, economic, and psychosocial distance or proximity and may result in exchanges of information, labor assistance, loans, services, or moral support. Patron/client relations may be direct, or the "patron" may be an intermediary. Some reciprocal networks display a pattern of incipient asymmetry leading to formation of true patron/client ties and some petty entrepreneurs or intermediaries manage to develop true patron/client networks; case histories are used to illustrate both phenomena.

    Colling, James David

    1995-01-01

    An experimental study was conducted to investigate the effects of controllable articulating winglets on glide performance and yawing moments of high performance sailplanes. Testing was conducted in the Texas A&M University 7 x 10 foot Low Speed Wind Tunnel using a full-scale model of the outboard 5.6 feet of a 15 meter class high performance sailplane wing. Different wing tip configurations could be easily mounted to the wing model. A winglet was designed in which the cant and toe angles as well as a rudder on the winglet could be adjusted to a range of positions. Cant angles used in the investigation consisted of 5, 25, and 40 degrees measured from the vertical axis. Toe-out angles ranged from 0 to 22.5 degrees. A rudder on the winglet was used to study the effects of changing the camber of the winglet airfoil on wing performance and wing yawing moments. Rudder deflections consisted of-10, 0, and 10 degrees. Test results for a fixed geometry winglet and a standard wing tip are presented to show the general behavior of winglets on sailplane wings, and the effects of boundary-layer turbulators on the winglets are also presented. By tripping the laminar boundary-layer to turbulent before laminar separation occurs, the wing performance was increased at low Reynolds numbers. The effects on the lift and drag, yawing moment, pitching moment, and wing root bending moment of the model are presented. Oil flows were used on the wing model with the fixed geometry winglet and the standard wing tip to visualize flow directions and areas of boundary layer transition. A cant angle of 25 degrees and a toe-out angle of 2.5 degrees provided an optimal increase in wing performance for the cant and toe angles tested. Maximum performance was obtained when the winglet rudder remained in the neutral position of zero degrees. By varying the cant, toe, and rudder angles from their optimized positions, wing performance decreases. Although the winglet rudder proved to be more effective in

    Full Text Available Introduction: According to the definition of the role of the Family Physician (FP presented in the statement of the European Wonca 2002, one of her/his features is the ability of coordination of care, and management of the interface with other specialties. However, there are serious problems of coordination between the levels of assistance, as showed by the discontinuity of care when patients are hospitalized. With the aim of raising awareness and analyze a particular case of interface between the Primary Health Care (PHC and Hospital, and how important is the success of a good collaboration, this case is reported. Description of case: Male, 50 years old, caucasian race, inserted into a nuclear family in the stage VI Duvall’s cycle. A gastric adenocarcinoma by his FP was diagnosed at 49 years old. The patient was referenced to urgent consultation of general surgery. With various surgical complications he had a long internment. A poorly differentiated and infiltrating gastric carcinoma at the stage T3 N1 Mx, with poor prognosis, was confirmed. There was serious lack of interface and gaps in information between the hospital and the PHC. There was a bad care of the patient, with worsening of his condition. At the insistence of the FP, the articulation becomes effective and there was improved in quality of care and of the general condition of the patient. Conclusion: A proper interface and coordination of care contributed to better quality of life and satisfaction of patients, with positive repercussions for their families, to health professionals involved and to the National Health Service. The completion of the FP core competencies will only be possible when his/her proper function will be recognized and known by all the other health professionals.Note: The speciality physician denomination changes according to the country; in Brazil, it receives the name of Medicina de Família e Comunidade.

    Full Text Available Background and Objectives: For mounting the maxillary cast to articulator, minimum three reference points not on single line, decide the plane to which maxillary cast is mounted. Variations exist in condylar guidance when different anterior reference points are used to mount the cast. Type of articulator may have influence on condylar guidance.A clinical study was planned to evaluate the effects of different anterior points of reference and two different articulator systems on condylar guidance. Materials and Methods: Total 15 subjects were selected. Six sets of maxillary casts were obtained. Face bow record was made using orbitale as anterior point of reference and the record was transferred to the Arcon and Non-Arcon articulator. The second and third mounting on Arcon and Non-Arcon articulator were done using Superior and inferior annular groove on incisal pin of articulator. Protrusive interocclusal records were made for all the subjects. Two lateral cephalograms one in maximum intercuspation and the other in protrusion for left and right side were taken. Anatomic condylar guidance of the subject were obtained from radiograph tracing. Arcon and Non-arcon articulator were programmed with Protrusive interocclusal record of the subjects and the condylar guidance was tabulated for right and left side. The procedure was repeated for all three mountings for both the articulators. Results: The orbitale is the best reference point which mounts maxillary cast closer to anatomic position. Inferior annular groove can also be used as anterior point of the reference. The superior annular groove is not recommended anterior point of reference.

  2. On Interlayer Stability and High-Cycle Simulator Performance of Diamond-Like Carbon Layers for Articulating Joint Replacements

    2014-06-01

    Full Text Available Diamond like carbon (DLC coatings have been proven to be an excellent choice for wear reduction in many technical applications. However, for successful adaption to the orthopaedic field, layer performance, stability and adhesion in physiologically relevant setups are crucial and not consistently investigated. In vitro wear testing as well as adequate corrosion tests of interfaces and interlayers are of great importance to verify the long term stability of DLC coated load bearing implants in the human body. DLC coatings were deposited on articulating lumbar spinal disks made of CoCr28Mo6 biomedical implant alloy using a plasma-activated chemical vapor deposition (PACVD process. As an adhesion promoting interlayer, tantalum films were deposited by magnetron sputtering. Wear tests of coated and uncoated implants were performed in physiological solution up to a maximum of 101 million articulation cycles with an amplitude of ±2° and −3/+6° in successive intervals at a preload of 1200 N. The implants were characterized by gravimetry, inductively coupled plasma optical emission spectrometry (ICP-OES and cross section scanning electron microscopy (SEM analysis. It is shown that DLC coated surfaces with uncontaminated tantalum interlayers perform very well and no corrosive or mechanical failure could be observed. This also holds true in tests featuring overload and third-body wear by cortical bone chips present in the bearing pairs. Regarding the interlayer tolerance towards interlayer contamination (oxygen, limits for initiation of potential failure modes were established. It was found that mechanical failure is the most critical aspect and this mode is hypothetically linked to the α-β tantalum phase switch induced by increasing oxygen levels as observed by X-ray diffraction (XRD. It is concluded that DLC coatings are a feasible candidate for near zero wear articulations on implants, potentially even surpassing the performance of ceramic vs

    To determine the content of integrated curricula, clinical concepts and the underlying basic science concepts need to be made explicit. Preconstructed concept maps are recommended for this purpose. They are mainly constructed by experts. However, concept maps constructed by residents are hypothesized to be less complex, to reveal more tacit basic science concepts and these basic science concepts are expected to be used for the organization of the maps. These hypotheses are derived from studies about knowledge development of individuals. However, integrated curricula require a high degree of cooperation between clinicians and basic scientists. This study examined whether there are consistent variations regarding the articulation of integration when groups of experienced clinicians and basic scientists and groups of residents and basic scientists-in-training construct concept maps. Seven groups of three clinicians and basic scientists on experienced level and seven such groups on resident level constructed concept maps illuminating clinical problems. They were guided by instructions that focused them on articulation of integration. The concept maps were analysed by features that described integration. Descriptive statistics showed consistent variations between the two expertise levels. The concept maps of the resident groups exceeded those of the experienced groups in articulated integration. First, they used significantly more links between clinical and basic science concepts. Second, these links connected basic science concepts with a greater variety of clinical concepts than the experienced groups. Third, although residents did not use significantly more basic science concepts, they used them significantly more frequent to organize the clinical concepts. The conclusion was drawn that not all hypotheses could be confirmed and that the resident concept maps were more elaborate than expected. This article discusses the implications for the role that residents and

  4. On the Power of Music: Using 'Cosmos' and 'Anthropos' to Articulate a Holistic Approach to Discussing the Power of Music

    Directory of Open Access Journals (Sweden)

    Brian R. Cates

    2013-05-01

    Full Text Available Music is an experience that is universal to all of mankind, no matter one’s race, gender, culture, or socioeconomic status. Whether it’s beholding one of Mahler’s symphonies in Carnegie Hall or listening to the “No. 1 Top Single” on iTunes using headphones, one truth is evident: music moves. The statement “music moves” inherently possesses an implication of the 'cosmic' and the 'anthropic’ nature of music – a holistic union of both mystery and humanity. This one truth has been the subject of an ongoing 2,000 year-old discussion that attempts to articulate the powerful reaction that results from experiencing music in all forms, beginning with the ancient Greeks of antiquity who possessed a cosmologically-grounded explanation to the power of music. However, as time moved forward, this cosmological, mysterious paradigm of the power of music slowly began to incorporate explainable and tangible anthropological articulations of the power of the music with respect to the human emotions, senses, and thoughts. This incorporation of anthropos reached a climax in the Renaissance era with the ushering in of humanism, which stripped away the mysterious and replaced the cosmologically-grounded explanation of music with the anthropologically-grounded view of naturalism. Since this profound departure from cosmos, society seems to be at a loss in articulating accurate reactions to music. This paper offers two proposals with respect to musical thought, one for society at large and one for the individual. I assert in this paper that society, in general, needs to return to an appreciation of the cosmos, the answerable, and the mysterious in nature, and that the individual needs to commence thinking holistically with respect to music—incorporating both cosmic and anthropic thought. I have reached my conclusions, assertions, and propositions based on this thesis by critically analyzing both primary and secondary resources in the form of the

    Several Indigenous communities around the globe maintain unique conceptions of mental illness and disorder. The Q'eqchi' Maya of southern Belize represent one Indigenous community that has maintained, due to highly "traditional" ways of life and the strong presence of many active localized healers or bush doctors, distinct conceptions of mental disorders as compared to Western psychiatric nosology. The purpose of this ethnographic study was to understand and interpret Q'eqchi' nosological systems of mental disorders involving the factors--spiritual, cultural, social, historical, cosmological, or otherwise--implicated in their articulation and construction. Over a period of 9 months, and with the help of cultural advisors from several Q'eqchi' communities, 94 interviews with five different traditional Q'eqchi' healers were conducted. This paper demonstrates that the mental illnesses recognized by the Q'eqchi' healers involved narrative structures with recognizable variations unfolding over time. What we present in this paper are 17 recognizable illnesses of the mind grouped within one of four broad "narrative genres." Each genre involves a discernible plot structure, casts of characters, themes, motifs, and a recognizable teleology or "directedness." In narrative terms, the healer's diagnostic and therapeutic work can be understood as an ability to discern plot, to understand and interpret a specific case within the board, empirically based structure of Q'eqchi' medical epistemology.

    Prescribing is the most common healthcare intervention, and is both beneficial and risky. An important source of risk in UK general practice is the management of 'repeat prescriptions', which are typically requested from and issued by non-clinically trained reception staff with only intermittent reauthorisation by a clinical prescriber. This paper ethnographically examines the formal and informal work employed by GPs and receptionists to safely conduct repeat prescribing work in primary care using Strauss's (1985, 1988, 1993) concept of 'articulation work' across eight UK general practices. The analytical lens of articulation work provided an investigative framing to contextually map the informal, invisible resources of resilience and strength employed by practice team members in the achievement of repeat prescribing safety, where risk and vulnerability were continually relocated across space and time. In particular, the paper makes visible the micro-level competencies and collaborative practices that were routinely employed by both GPs and receptionists across different socio-cultural contexts, with informal, cross-hierarchical communication usually considered more effective than the formal structures of communication that existed (e.g. protocols). While GPs held formal prescribing authority, this paper also examines the key role of receptionists in both the initiation and safe coordination of the repeat prescribing routine. PMID:26283462

    Total hip arthroplasty for intracapsular femoral neck fractures (FNF) is associated with a greater risk of dislocation. Dual articulation systems in this group of patients may provide better implant stability and a reduced dislocation rate. The aim of our study was to investigate FNF patients treated with dual articulation cups (DAC) and conventional THA and compare their clinical results at four months and one year after surgery. Our study compared femoral neck fracture patients treated with either DAC or conventional THA during two different time periods. Before surgery and during follow-up, the patients answered questions regarding their mobility, pain and usage of walking aids. Additionally at four-month and one-year follow-ups EQ-5D and HOOS questionnaires were applied for those patients qualifying for functional and quality of life analysis. Out of 125 femoral neck fracture patients 58 were treated with DAC and 67 with conventional THA. At four months and one year follow-up the HOOS and EQ-5D results did not differ significantly between DAC and conventional THA. Five hips in the THA group were revised for recurrent dislocation and two had a single dislocation. One year after surgery, the functional result of DAC and conventional THA are comparable but DAC have a lower risk of dislocation. PMID:23397197

  4. ITER articulated inspection arm (AIA): R and D progress on vacuum and temperature technology for remote handling

    International Nuclear Information System (INIS)

    To perform an intervention a short time after plasma shutdown, the operation of the robot will have to be under ITER conditions which means: under high vacuum, pollution avoidance and a temperature ambience around 120 C. The feasibility studies have led to the design of a robot in the shape of a 8.2 meter long articulated arm made up of 5 modules with 11 articulated joints. A single module prototype has been manufactured to be tested. The prototype was set up in a specific vacuum vessel at Tore-Supra facility that can be baked up to 230 C under high-vacuum conditions. The first tests have shown that: -) the efficiency of the actuators at 120 C was the same than in air at room temperature, the speed was slightly lower, -) the monitoring of the temperature of the motor and of the power electronics components showed an increasing of only 40 C during 3 full pitch movements, and -) most of the greases was degassed during the 1 week long baking at 200 C except one which comes from an organic material in a component that has to be identified

  5. Investigating pianists' individuality in the performance of five timbral nuances through patterns of articulation, touch, dynamics and pedalling

    Full Text Available Timbre is an essential expressive feature in piano performance. Concert pianists use a vast palette of timbral nuances to colour their performances at the microstructural level. Although timbre is generally envisioned in the pianistic community as an abstract concept carried through an imaged vocabulary, performers may share some common strategies of timbral expression in piano performance. Yet there may remain further leeway for idiosyncratic processes in the production of piano timbre nuances. In this study, we examined the patterns of timbral expression in performances by four expert pianists. Each pianist performed four short pieces, each with five different timbral intentions (bright, dark, dry, round, and velvety. The performances were recorded with the high-accuracy Bösendorfer CEUS system. Fine-grained performance features of dynamics, touch, articulation and pedalling were extracted. Reduced PCA performance spaces and descriptive performance portraits confirmed that pianists exhibited unique, specific profiles for different timbral intentions, derived from underlying traits of general individuality, while sharing some broad commonalities of dynamics and articulation for each timbral intention. These results confirm that pianists’ abstract notions of timbre correspond to reliable patterns of performance technique. Furthermore, these effects suggest that pianists can express individual styles while complying with specific timbral intentions.

    Full Text Available The comorbidity of bipolar disorder and anxiety disorders is a well known concept. Obsessive-compulsive disorder is the most commonly seen comorbid anxiety disorder in bipolar patients. Some genetic variants, neurotransmitters especially serotonergic systems and second-messenger systems are thought to be responsible for its etiology. Bipolar disorder alters the clinical aspects of obsessive compulsive disorder and is associated with poorer outcome. The determination of comorbidity between bipolar disorder and obsessive compulsive disorder is quite important for appropriate clinical management and treatment.

    Movement disorders can be hypokinetic (e.g., parkinsonism), hyperkinetic, or dystonic in nature and commonly arise from altered function in nuclei of the basal ganglia or their connections. As obvious structural changes are often limited, standard imaging plays less of a role than in other neurologic disorders. However, structural imaging is indicated where clinical presentation is atypical, particularly if the disorder is abrupt in onset or remains strictly unilateral. More recent advances in magnetic resonance imaging (MRI) may allow for differentiation between Parkinson's disease and atypical forms of parkinsonism. Functional imaging can assess regional cerebral blood flow (functional MRI (fMRI), positron emission tomography (PET), or single-photon emission computed tomography (SPECT)), cerebral glucose metabolism (PET), neurochemical and neuroreceptor status (PET and SPECT), and pathologic processes such as inflammation or abnormal protein deposition (PET) (Table 49.1). Cerebral blood flow can be assessed at rest, during the performance of motor or cognitive tasks, or in response to a variety of stimuli. In appropriate situations, the correct imaging modality and/or combination of modalities can be used to detect early disease or even preclinical disease, and to monitor disease progression and the effects of disease-modifying interventions. Various approaches are reviewed here. PMID:27430452

  12. Technique of the modified hammock for the extra-articulate stabilization of the knee in rupture of the cranial cruciate ligament in canine

    Directory of Open Access Journals (Sweden)

    Pedro Pablo Martínez Méndez

    2005-05-01

    Full Text Available The anterior cruciform ligament is the main articulation stabilizer of the canine knee. Its lesion has a degree of uncertainty that unchains a degenerative osteoarthritis and damage to the internal meniscus in most of the cases. The rupture of the anterior cruciform ligament (RACL is one of the most common pathologies in canine’s knee. This pathology is related to the patient conditions such as size, weight, exercise, and diverse biomechanical factors of each animal. RACL is generally accompanied by complications like lesions on the meniscus and ligaments, inflammation and pain. For treatment of RACL they have set up a wide variety of surgical methods, which implies a total approaching of the articulation. The modified hammock method allows a successful resolution of the problem with a minimally invasive approaching and excellent articulation stabilization which allows a quick recovery and adequate.

    The mal-positioning of total hip arthroplasty components can result in edge loading conditions. Purpose of this study was to determine if the wear rate of ceramic-on-ceramic and metal-on-polyethylene increases under edge loading conditions. The literature was reviewed to determine which of the commonly used hip bearings is the most forgiving to implant mal-orientation. Two 28-mm ceramic-on-ceramic articulations were tested in vitro: pure alumina (PAL) ceramic versus the new alumina-toughened zirconia (ATZ). Two 28-mm metal-on-polyethylene articulations were tested in vitro: conventional ultrahigh molecular weight polyethylene (UHMWPE) versus highly crosslinked polyethylene (HXLPE) stabilized with vitamin E. All bearings were tested at standard and at highest possible inclination angles. Hip simulator tests were run for five million cycles based on N = 3 tests per condition. The average wear rate of ATZ-on-ATZ is 0.024 mm(3) /Mcycles at 45° and 0.018 mm(3) /Mcycles at 65°. Wear rate of PAL-on-PAL is between 0.02 and 0.03 mm(3) /Mcycles at 45°, as well as 65°. The wear rate of UHMWPE was 31 ± 1 mm(3) /Mcycles at an inclination angle of 45° and 26 ± 1 mm(3) /Mcycles at 80°. The wear rate of vitamin E stabilized HXLPE was 5.9 ± 0.2 mm(3) /Mcycles at 45° and 5.8 ± 0.2 mm(3) /Mcycles at 80°. Edge loading does not increase the wear rate of ceramic-on-ceramic and metal-on-polyethylene articulations. The newest biomaterials showed markedly lower wear rates compared with their conventional counterparts. ATZ-on-ATZ showed the lowest wear rate of all tested pairings, but the vitamin E stabilized HXLPE seems to be the most forgiving material when it comes to implant mal-orientation. PMID:24652696

    In two experiments, we examined the contribution of articulation-specific features to visual word recognition during the reading of Chinese. In spoken Standard Chinese, a syllable with a full tone can be tone-neutralized through sound weakening and pitch contour change, and there are two types of two-character compound words with respect to their articulation variation. One type requires articulation of a full tone for each constituent character, and the other requires a full- and a neutral-tone articulation for the first and second characters, respectively. Words of these two types with identical first characters were selected and embedded in sentences. Native speakers of Standard Chinese were recruited to read the sentences. In Experiment 1, the individual words of a sentence were presented serially at a fixed pace while event-related potentials were recorded. This resulted in less-negative N100 and anterior N250 amplitudes and in more-negative N400 amplitudes when targets contained a neutral tone. Complete sentences were visible in Experiment 2, and eye movements were recorded while participants read. Analyses of oculomotor activity revealed shorter viewing durations and fewer refixations on-and fewer regressive saccades to-target words when their second syllable was articulated with a neutral rather than a full tone. Together, the results indicate that readers represent articulation-specific word properties, that these representations are routinely activated early during the silent reading of Chinese sentences, and that the representations are also used during later stages of word processing.

    Language disorders are identified when a person has difficulty with expressive language, receptive language, or pragmatic language. Speech disorders are identified when a person's voice, fluency, or articulation call attention to the speaker because his or her speech is sufficiently different from the norm. Speech and language development should be consistent with a child's overall development and can be tracked using typical milestone markers. Differential diagnosis is critical to designing appropriate intervention, which should be tailored to the parents' goals along with the child's clinical and educational needs. Early identification and intervention assist in educational planning and are often associated with better long-term outcomes. Any speech-language therapy plan should be designed with measurable goals and consistent monitoring of progress toward those goals. PMID:18929058

    Full Text Available Myotonia reflects a state of muscle fiber hyperexcitability. Impaired transmembrane conductance of either chloride or sodium ions results in myotonia. Myotonic disorders include the myotonic dystrophies and nondystrophic myotonias. Mutations in the genes encoding chloride (ClC-1 or sodium (SCN4A channels expressed exclusively in skeletal muscle cause nondystrophic myotonias. Genetic defects in the myotonic dystrophies do not involve ion channel or its regulator proteins. Recent research supports a novel RNA-mediated disease mechanism of myotonia in the myotonic dystrophies. Myotonic dystrophy Type 1 is caused by CTG repeat expansion in the 3′ untranslated region in the Dystrophia Myotonica Protein Kinase (DMPK gene. Myotonic dystrophy Type 2 is caused by CCTG repeat expansion in the first intron in Zinc Finger Protein 9 (ZNF9 gene. The expanded repeat is transcribed in RNA and forms discrete inclusions in nucleus in both types of myotonic dystrophies. Mutant RNA sequesters MBNL1, a splice regulator protein and depletes MBNL1 from the nucleoplasm. Loss of MBNL1 results in altered splicing of ClC-1 mRNA. Altered splice products do not encode functional ClC-1 protein. Subsequent loss of chloride conductance in muscle membrane causes myotonia in the myotonic dystrophies. The purpose of this review is to discuss the clinical presentation, recent advances in understanding the disease mechanism with particular emphasis on myotonic dystrophies and potential therapy options in myotonic disorders.

    The purpose of this article is to discuss professional education and training programs offered to teams of operators by the main company in the area of Bacia de Campos (Petrobras), Rio de Janeiro, Brazil. It also discusses the necessary skills to the new functions derived from the implementation of an organizational innovation, the polyvalence, and how such innovation has impacted operators' activity. By using elements of WEA and the device "Meetings on the Work" it was possible to gain a better understanding of both the distance between the dimensions of prescribed work and real work, and the articulation between outsourcing and the proposition of polyvalence, which have stimulated the creation of new functions, namely, the polyvalent operator and the operator-maintainer, this latter being in fact an evolvement of the first.

    This study aims to contribute to an emerging literature that seeks to understand how identity markers on social networking sites (SNSs) shape interpersonal impressions, and particularly the boundaries that SNSs present for articulating unconstrained "hoped-for possible selves." An experiment employing mock-up Facebook profiles was conducted, showing that appearing with friends on a Facebook profile picture as well as increasingly higher number of Facebook friends strengthened perceptions of a profiler's hoped-for level of social connectedness. Excessive numbers of friends, however, weakened perceptions of a profiler's real-level social connectedness, particularly among participants with smaller social networks on Facebook themselves. The discussion focuses on when people come to find that reasonable boundaries of self-generated information on an SNS have been exceeded. PMID:21476838

    Antibiotic spacer designs have proven effective at eradicating infection during a two-stage revision arthroplasty. Temporary reuse of the steam-sterilized femoral component and a new all poly tibia component has been described as an effective articulating antibiotic spacer, but sterility concerns persist. Six explanted cobalt chrome femurs from patients with grossly infected TKA's and six stock femurs inoculated with different bacterial species were confirmed to be bacteria-free after autoclaving under a standard gravity-displacement cycle. The effect of steam sterilization on cobalt chrome fragments contaminated with MRSA biofilm was analyzed microscopically to quantify remaining biofilm. The autoclave significantly reduced the biofilm burden on the cobalt chrome fragments. This study confirmed sterility of the femur after a standard gravity-displacement cycle (132°C, 27 PSIG, 10 minutes). PMID:26282497

    Full Text Available This paper explores two experimental documentary films that present memories of acts of mass violence: The Act of Killing (Denmark, 2012, director Joshua Oppenheimer about the Indonesian anti-Communist purge in the 1960s and Gzim Rewind (Sweden, 2011, director Knutte Wester about the fate of a boy who fled from Kosovo in the 1990s. Using dialogic theory (Bakhtin, 1981; Phillips, 2011, we analyse the voices that are articulated about past violent events in the films. The focus is on how different voices interrelate in the filmic presentation of mass violence, including victims and killers. Primarily, the analysis focuses on The Act of Killing and its reception by an Indonesian audience. The discussion concerns how these kinds of film projects open up very different voices and how this diversity potentially contributes to new understandings of the past, thereby fuelling social and political change.

After applying a novel approach to the AACMM kinematic parameter identification problem, by means of a single calibration gauge object, a one-step calibration method to obtain both intrinsic―laser plane, CCD sensor and camera geometry―and extrinsic parameters related to the AACMM main frame has been developed. This allows the integration of LTS and AACMM mathematical models without the need of additional optimization methods after the prior sensor calibration, usually done in a coordinate measuring machine (CMM before the assembly of the sensor in the arm. The experimental tests results for accuracy and repeatability show the suitable performance of this technique, resulting in a reliable, quick and friendly calibration method for the AACMM final user. The presented method is also valid for sensor integration in robot arms and CMMs.

    2014-08-01

    Full Text Available Stringed instrument bowing is a complex coordinative motor skill acquired though years of intense practice. We apply a novel “freezing” analysis to investigate how movement at different joints contributes to bow transport (movement amplitude, stabilization of bow parameters (angle, velocity during bow movements, and quick reversals of bow direction (acceleration amplitude. Participants were ten advanced or professional cellists (19-32 years, at least 10 years of practice and ten age-matched novice players. Arm and bow movements were recorded using 3D motion capture. To assess how performance depends on articulated use of the right arm, actual data were compared to surrogate data, generated by artificially removing movement at (“freezing” individual joints in measured arm movements. This analysis showed that both elbow and shoulder significantly contribute to bow transport in experts, while only the shoulder contributed to bow transport in novices. Moreover, experts showed more strongly increased variability of bow parameters and reduced acceleration amplitudes at bow reversals for surrogate compared to actual movement data. This indicates that movement across joints was organized to reduce bow variability and achieve quick bow reversals. Corresponding effects were less pronounced or absent in the novices, in particular for the wrist and elbow. Our results demonstrate the importance of articulated use of the right arm and clarify the contribution of different joints in experts’ bowing performance. Moreover, they support theories of motor control and learning that propose exploitation of biomechanical degrees of freedom, in particular of distal joints, as a critical component in skilled motor performance.

The studies of oxytocin interventions in psychiatric disorders yielded potentially promising findings. This paper reviews the role of oxytocin in emotions, behavior and its effects in psychiatric disorders. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2016; 8(2: 102-113

    Arousal Disorders (AD) are motor behaviours arising from NREM sleep. They comprise a spectrum of manifestations of increasing complexity from confusional arousal to sleep terror to sleepwalking. AD usually appear in childhood with a low frequency of episodes and spontaneously disappear before adolescence. The advent of video-polysomnography disclosed the existence of other phenomena alongside AD, in particular nocturnal frontal lobe seizures, requiring a differential diagnosis from AD. History-taking is usually sufficient to establish a correct diagnosis of AD even though viewing the episodes is essential for the clinician to distinguish the different motor events. Videopolysomnographic recording in a sleep laboratory is not always necessary and homemade video-recordings are useful to capture events closest to real life episodes. PMID:22136894

    Full Text Available The study and documentation of occlusal-articulation relationships has a high diagnostic significance in patients with bruxism and bruxomania. The study aims on the basis of registration of occlusal contacts via articulating paper and the T-Scan system to evaluate the advantages and disadvantages of both methods in occlusal diagnosis of patients with bruxism and bruxomania. Material and Methods: 40 patients with bruxism and / or bruxomania (29 women and 11 men aged between 21 and 77 years from October 2010 to February 2014 was conducted computerized occlusal analysis using the systems T-Scan II (in 12 patients, T-Scan III (in 28 patients and the software T-Scan III. All patients were subjected to registration of occlusal relationships in centric occlusion (CO with articulating paper Bausch PROGRESS 100 µ and Bausch® Arti-Fol® 8 µ. Results and Discussion: In 90.0% of patients it is established unevenly distributed, irregular in size and intensity occlusal contacts. Essential factor for preventing the spontaneous bilateral closure with balanced forces is the presence of interceptive contacts and sliding occurring in the first frame of the occlusion time until the maximum intercuspation - MIP. Conclusion: Registration with articulating paper visualizes cumulative picture of the contacts in CO and interceptive contacts without being able to distinguish them in size and time of onset. Computerized occlusal analysis objectively and quantitatively determines interceptive contacts and distinguishes them from contacts in MIP and gives real meaning to the terms "strong" and "light contacts".

    Introduction Speech articulation disorders affect the intelligibility of speech. Studies on therapeutic models show the effectiveness of the communication treatment. Objective To analyze the progress achieved by treatment with the ABAB-Withdrawal and Multiple Probes Model in children with different degrees of phonological disorders. Methods The diagnosis of speech articulation disorder was determined by speech and hearing evaluation and complementary tests. The subjects of this research were eight children, with the average age of 5:5. The children were distributed into four groups according to the degrees of the phonological disorders, based on the percentage of correct consonants, as follows: severe, moderate to severe, mild to moderate, and mild. The phonological treatment applied was the ABAB-Withdrawal and Multiple Probes Model. The development of the therapy by generalization was observed through the comparison between the two analyses: contrastive and distinctive features at the moment of evaluation and reevaluation. Results The following types of generalization were found: to the items not used in the treatment (other words), to another position in the word, within a sound class, to other classes of sounds, and to another syllable structure. Conclusion The different types of generalization studied showed the expansion of production and proper use of therapy-trained targets in other contexts or untrained environments. Therefore, the analysis of the generalizations proved to be an important criterion to measure the therapeutic efficacy. PMID:25992107

    De Luca Picione, Raffaele; Freda, Maria Francesca

    2016-03-01

    The notion of the border is an interesting advancement in research on the processes of meaning making within the cultural psychology. The development of this notion in semiotic key allows to handle with adequate complexity construction, transformation, stability and the breakup of the relationship between person/world/otherness. These semiotic implications have already been widely discussed and exposed by authors such Valsiner (2007, 2014), Neuman (2003, 2008), Simão (Culture & Psychology, 9, 449-459, 2003, Theory & Psychology, 15, 549-574, 2005, 2015), with respect to issues of identity/relatedness, inside/outside, stability/change in the irreversible flow of the time. In this work, after showing some of the basics of such semiotic notion of border, we discuss the processes of construction and transformation of borders through the modal articulation, defined as the contextual positioning that the person assumes with respect to the establishment of a boundary in terms of necessity, obligation, willingness, possibility, permission, ability. This modal subjective positioning acquires considerable interest from the clinical point of view since its degree of plasticity vs that of rigidity is the basis of processes of development or stiffening of relations between person/world/otherness.

  9. What governs the transition to a sustainable hydrogen economy? Articulating the relationship between technologies and political institutions

    International Nuclear Information System (INIS)

    There is a lack of integrated knowledge on the transition to a sustainable energy system. The paper focuses on the relationship between technologies and institutions in the field of hydrogen from the perspective of political theory. The paper unfolds four paradigms of governance: 'Governance by policy networking', Governance by government', 'Governance by corporate business', and 'Governance by challenge', and looks into the major line of argument in support of these paradigms and into their possible bias with respect to hydrogen options. Each of these paradigms reveals an institutional bias in that it articulates specific opportunities for collaboration and competition in order to stimulate the transition to a sustainable hydrogen economy. The paper makes the observation that there is a compelling need to reframe fashionable discourse such as the necessary shift from government to governance or from government to market. Instead, specific questions with respect to the impact of guiding policy frameworks on innovation will highlight that neither 'neutral' nor 'optimal' frameworks for policy making exist, where competing hydrogen options are at stake. The identification of paradigms of governance maybe considered a methodological device for (participator) policy analysis

  10. Application of articulated absolute co-ordinate measuring machine for quality control in manufacturing of ELM control coil

    International Nuclear Information System (INIS)

    Under India-EU collaboration, Institute for Plasma Research had undertaken an engineering feasibility initiative aimed at developing a 1:1 prototype Edge Localized Modes control coils (ELM CC) for Joint European Torus (JET). The ELM coils comprised of winding pack made of CuCrZr conductor encased in Inconel 625 casing. The ELM control coils are designed in saddle coil configuration having toroidal and poloidal curves similar to that of JET vacuum vessel. ELM coil are in-vessels coils forming the primary boundary with torus vacuum which demands stringent requirement for its quality aspects. The dimensional accuracies of winding pack and casing are critical for its encasing and remote assembly inside vacuum vessel. The articulated arm co-ordinate measuring machine (AACMM) has been extensively used for dimensional metrology of ELM CC from winding to its encasing. The inspection methodology and procedures using noncontact technique for ELM CC with AACMM has been developed and established with extensive trials. The winding pack, their formers and final ELM control coils has been systematically investigated for their dimensional accuracies with AACMM. The effectiveness of AACMM based evaluation for quality control in fabrication of 1:1 prototype of ELM CC has been presented in this paper. (author)

    2015-03-01

    Full Text Available This paper presents the implementation of an adaptive supervisory sliding fuzzy cerebellar model articulation controller (FCMAC in the speed sensorless vector control of an induction motor (IM drive system. The proposed adaptive supervisory sliding FCMAC comprised a supervisory controller, integral sliding surface, and an adaptive FCMAC. The integral sliding surface was employed to eliminate steady-state errors and enhance the responsiveness of the system. The adaptive FCMAC incorporated an FCMAC with a compensating controller to perform a desired control action. The proposed controller was derived using the Lyapunov approach, which guarantees learning-error convergence. The implementation of three intelligent control schemes—the adaptive supervisory sliding FCMAC, adaptive sliding FCMAC, and adaptive sliding CMAC—were experimentally investigated under various conditions in a realistic sensorless vector-controlled IM drive system. The root mean square error (RMSE was used as a performance index to evaluate the experimental results of each control scheme. The analysis results indicated that the proposed adaptive supervisory sliding FCMAC substantially improved the system performance compared with the other control schemes.

  12. Dynamic navigation simulation of an articulated multi-link arm for in-vessel inspection tasks in a Tokamak

    International Nuclear Information System (INIS)

    This paper is part of the remote handling (RH) activities towards preparedness for the future fusion machines. The aim of the R and D program performed is to demonstrate the feasibility of the inspection tasks inside the Vacuum Vessel. Due to the toroidal geometry and huge dimensions of the Vacuum Vessel, there is an inevitable need of a precise and fast automated articulated inspection system that can perform the required inspection tasks without damaging the surface and to maintain the machine availability for the maximum time. When considering generic Tokamak relevant conditions, the set of major challenges for the Remote Equipment is to sustain the severe operating conditions: ultra high vacuum, temperature and tritium level. The limited number of machine access ports and the very constrained environment complicate the introduction of a robot into the machine. The Multi Link inspection arm is required to be deployed in the bounded environment inside the Tokamak Vessel. This paper presents the development of software for implementation of autonomous navigation motion control algorithms based design simulations for the inspection Arm for routine inspection tasks, navigation to the targeted coordinates inside the Vessel, clash avoidance and to perform other auxiliary mechanical tasks. The software is also capable to store the joints and frame locations at every interval which can be used for the real time control application. The developed software has the flexibility to work with any number of links and joints. (author)

  13. Differential Control Strategy based on an Equal Slip Rate for an All-wheel Electricdrive Underground Articulated Dumping Truck

    Directory of Open Access Journals (Sweden)

    Jin Chun

    2014-09-01

    Full Text Available A differential control strategy based on equal slip rates is introduced to improve the steering stability of an all-wheelelectric-drive underground articulated dumping truck. Steering kinematic and dynamic models of the truck are derived to describe the movement relationship and force of the driving wheels. In consideration of the difficulty of obtaining the absolute velocity for an all-wheel-drive truck, an acceleration sensor was set on a test truck, and a kalman filter was applied to obtain the actual value for the truck body. Simulation results for an equal-slip control strategy were compared with experimental results for an equal-torque control strategy. In the simulation, the four-wheel slip rate was 0.08 and the steering system of the truck was stable. The results verify that the equal-slip control strategy makes better use of the ground adhesion coefficient, is able to reasonably distribute drive power, notably reduces tire wear, and improves the use of driving power.

  14. High-precision robotic microcontact printing (R-μCP) utilizing a vision guided selectively compliant articulated robotic arm.

    McNulty, Jason D; Klann, Tyler; Sha, Jin; Salick, Max; Knight, Gavin T; Turng, Lih-Sheng; Ashton, Randolph S

    2014-06-01

    Increased realization of the spatial heterogeneity found within in vivo tissue microenvironments has prompted the desire to engineer similar complexities into in vitro culture substrates. Microcontact printing (μCP) is a versatile technique for engineering such complexities onto cell culture substrates because it permits microscale control of the relative positioning of molecules and cells over large surface areas. However, challenges associated with precisely aligning and superimposing multiple μCP steps severely limits the extent of substrate modification that can be achieved using this method. Thus, we investigated the feasibility of using a vision guided selectively compliant articulated robotic arm (SCARA) for μCP applications. SCARAs are routinely used to perform high precision, repetitive tasks in manufacturing, and even low-end models are capable of achieving microscale precision. Here, we present customization of a SCARA to execute robotic-μCP (R-μCP) onto gold-coated microscope coverslips. The system not only possesses the ability to align multiple polydimethylsiloxane (PDMS) stamps but also has the capability to do so even after the substrates have been removed, reacted to graft polymer brushes, and replaced back into the system. Plus, non-biased computerized analysis shows that the system performs such sequential patterning with <10 μm precision and accuracy, which is equivalent to the repeatability specifications of the employed SCARA model. R-μCP should facilitate the engineering of complex in vivo-like complexities onto culture substrates and their integration with microfluidic devices. PMID:24759945

  15. A self-centering active probing technique for kinematic parameter identification and verification of articulated arm coordinate measuring machines

    International Nuclear Information System (INIS)

    A crucial task in the procedure of identifying the parameters of a kinematic model of an articulated arm coordinate measuring machine (AACMM) or robot arm is the process of capturing data. In this paper a capturing data method is analyzed using a self-centering active probe, which drastically reduces the capture time and the required number of positions of the gauge as compared to the usual standard and manufacturer methods. The mathematical models of the self-centering active probe and AACMM are explained, as well as the mathematical model that links the AACMM global reference system to the probe reference system. We present a self-calibration method that will allow us to determine a homogeneous transformation matrix that relates the probe's reference system to the AACMM last reference system from the probing of a single sphere. In addition, a comparison between a self-centering passive probe and self-centering active probe is carried out to show the advantages of the latter in the procedures of kinematic parameter identification and verification of the AACMM

  16. ITER articulated inspection arm (AIA): R and d progress on vacuum and temperature technology for remote handling

    International Nuclear Information System (INIS)

    This paper is part of the remote handling (RH) activities for the future fusion reactor ITER. The aim of the R and D program performed under the European Fusion Development Agreement (EFDA) work program is to demonstrate the feasibility of close inspection tasks such as viewing or leak testing of the Divertor cassettes and the Vacuum Vessel (VV) first wall of ITER. It is assumed that a long reach, limited payload carrier penetrates the ITER chamber through the openings evenly distributed around the machine such as In-Vessel Viewing System (IVVS) access or through upper port plugs. To perform an intervention a short time after plasma shut down, the operation of the robot should be realised under ITER conditioning i.e. under high vacuum and temperature conditions (120 oC). The feasibility analysis drove the design of the so-called articulated inspection arm (AIA) which is a 8.2 m long robot made of five modules with a 11 actuated joints kinematics. A single module prototype was designed in detail and manufactured to be tested under ITER realistic conditions at CEA-Cadarache test facility. As well as demonstrating the potential for the application of an AIA type device in ITER, this program is also dedicated to explore the necessary robotic technologies required to ITER's IVVS deployment system. This paper presents the whole AIA robot concept, the first results of the test campaign on the prototype vacuum and temperature demonstrator module

    Peemans, J P

    1995-01-01

    This work attempts to put certain problems of articulation between rural and urban areas in perspective in relation to the evolution of theories and doctrines of development. A sweeping overview of successive theories of economic development that have gained prominence since World War II is organized in terms of the dominant paradigms: that of "national modernization" from 1950 to 1965, that of "internationalization" from 1965 to 1980, and that of "globalization" beginning around 1980. Within each paradigm, the main tenets and implicit assumptions of the prevailing theories of development are spelled out, and the impact on the daily lives of residents of developing countries of theoretical views on the city and countryside expressed in macroeconomic development strategies are shown. The different paradigms define contemporary conceptualizations of development and are themselves reflections of historic contexts. The historic contexts are determined by the interactions that periodically alter structures of production and social relations within and between countries. The author expresses the view that theories of development have contributed little to the practical solution of problems of underdevelopment over the past half century, but the multidisciplinary response to the controversies they have aroused is an extraordinary indicator of debates on the state of the world.

  18. Design of sealing arrangements for development of leak tight articulated manipulator for waste management and reprocessing plants

    International Nuclear Information System (INIS)

    As a part of development of Remote handling equipment and gadgets, Leak tight Articulated Manipulator (ARTM) has been developed for shielded facilities of Nuclear Recycle Plant. The ARTM is a Master Slave Manipulator having 8 Kg Payload capacity and most suitable for shielded sampling cubicles of Waste Management plants and dilution hot cells of Reprocessing plants. All the motions and forces are transmitted from Master to slave arm through the mechanical linkages, which are housed inside the wall tube. The mechanical linkages and wall tube run across the shielded wall. The applications involving seal tightness of the glove boxes and dilution hot cells intend to use all the accessories including MSMs to be leak tight. During the design of leak tight ARTM, all the potential leak paths through the components of existing ARTM were examined critically and static and dynamic seals were designed based on the geometry and requirement of particular leak path. A leak proof testing set up was fabricated for evaluating the leak rates across the manipulator contemplating the actual operating conditions. The manipulator was subjected to the Friction, Rigidity and Leak tests. The results of the tests are satisfactory and as per the International standards available. The leak rates measured for different manipulators were in the range of 0.05 to 0.1 % of air volume/hr @ 200 mm of water columndifferential negative pressure. (author)

Recent epidemiological studies of anxiety disorders provided evidence of their high frequency in the general population worldwide. Anxiety disorders afflict an estimated 15.7 million people in the United States each year. Anxiety disorders are highly prevalent in adults with females showing higher preponderance of 2:1 as compared to males. Anxiety disorders are a group of mental disorders characterized by various combinations of key features - Irritability, fear, Insomnia, Nervousness, Tachycardia, Inability to concentrate, poor coping skills, Palpitation, Sweating, Agoraphobia and Social Withdrawal. The anxiety disorders, including panic disorder (PD, generalized anxiety disorder (GAD, social anxiety disorder (SAD, and posttraumatic stress disorder (PTSD, are among the disabling medical disorders. The neurobiology of anxiety disorders is not fully understood, but several different biologic abnormalities have been implicated in their etiology. The GABA, NE and 5HT systems play crucial roles in mediating the affective circuitry underlying the highly related clinical disorders of anxiety. Anxiety is a common psychiatric condition characterized by unnecessary aggression, poor quality of life, fear, worry, avoidance, and compulsive rituals that are associated with significant distress.

    The purpose of the present case study was to determine the long-term impact of partial glossectomy (using the keyhole technique) on overall speech intelligibility and articulation in a Dutch-speaking child with Beckwith-Wiedemann syndrome (BWS). Furthermore the present study is meant as a contribution to the further delineation of the phonation, resonance, articulation and language characteristics and oral behaviour in a child with BWS. Detailed information on the speech and language characteristics of children with BWS may lead to better guidance of pediatric management programs. The child's speech was assessed 9 years after partial glossectomy with regard to ENT characteristics, overall intelligibility (perceptual consensus evaluation), articulation (phonetic and phonological errors), voice (videostroboscopy, vocal quality), resonance (perceptual, nasometric assessment), language (expressive and receptive) and oral behaviour. A class III malocclusion, an anterior open bite, diastema, overangulation of lower incisors and an enlarged but normal symmetric shaped tongue were present. The overall speech intelligibility improved from severely impaired (presurgical) to slightly impaired (5 months post-glossectomy) to normal (9 years postoperative). Comparative phonetic inventory showed a remarkable improvement of articulation. Nine years post-glossectomy three types of distortions seemed to predominate: a rhotacism and sigmatism and the substitution of the alveolar /z/. Oral behaviour, vocal characteristics and resonance were normal, but problems with expressive syntactic abilities were present. The long-term impact of partial glossectomy, using the keyhole technique (preserving the vascularity and the nervous input of the remaining intrinsic tongue muscles), on speech intelligibility, articulation, and oral behaviour in this Dutch-speaking child with congenital macroglossia can be regarded as successful. It is not clear how these expressive syntactical problems

    Full Text Available Aim: The purpose of this study was comparative evaluation of sagittal condylar values of arcon and non-arcon articulators with cephalometric readings and to determine the amount of discrepancy in sagittal condylar guidance values between arcon and non-arcon articulators using same protrusive record. Materials and Methods: Twenty subjects in the age group of 19-35 years, free from temporomandibular joint dysfunction, and occlusal disharmony, with healthy dentition participated in the study. Hanau H2 (non-arcon type and Hanau Wide-Vue (arcon type articulators were programmed for sagittal condylar guidance values using the same protrusive record made in polysiloxane bite registration material with edge to edge degree of protrusion. The resultant values for both the articulators on either side were compared with values obtained from tracing of digital lateral cephalogram using Kodak Dental imaging Window software 6.6.3.0-C program. The tabulated data were subjected to statistical analysis, ANOVA (Fishers ′F′ test for group comparison, Tukey′s HSD test for inter-comparison, student′s unpaired ′t′ test for intra-group comparison, and level of significance (P was calculated using the same. Results: The mean sagittal condylar guidance values of the three different groups were found to be very highly significant (P=0.001 and highly significant (P=0.002 on the right and left sides respectively. There was a very highly significant difference (P=0.001 and highly significant difference (P=0.003 between the arcon and non-arcon group on the right and left side respectively. No significant difference was found between the arcon and cephalometric group (P=0.284 right, P=0.853 left and a statistically significant difference was found between the non-arcon and cephalometric group (P=0.049 right, P=0.015 left. On intragroup comparison there was no statistically significant difference in sagittal condylar values on the right and left sides. Conclusion

    Full Text Available Intermittent explosive disorder is an impulse control disorder characterized by the occurrence of discrete episodes of failure to resist aggressive impulses that result in violent assault or destruction of property. Though the prevalence intermittent explosive disorder has been reported to be relatively rare in frontier studies on the field, it is now common opinion that intermittent explosive disorder is far more common than previously thought especially in clinical psychiatry settings. Etiological studies displayed the role of both psychosocial factors like childhood traumas and biological factors like dysfunctional neurotransmitter systems and genetics. In differential diagnosis of the disorder, disorders involving agression as a symptom such as alcohol and drug intoxication, antisocial and borderline personality disorders, personality changes due to general medical conditions and behavioral disorder should be considered. A combination of pharmacological and psychotherapeutic approaches are suggested in the treatment of the disorder. This article briefly reviews the historical background, diagnostic criteria, epidemiology, etiology and treatment of intermittent explosive disorder.

    Full Text Available This article describes a school-based telehealth service delivery model and reports outcomes made by school-age students with speech sound disorders in a rural Ohio school district. Speech therapy using computer-based speech sound intervention materials was provided either by live interactive videoconferencing (telehealth, or conventional side-by-side intervention.  Progress was measured using pre- and post-intervention scores on the Goldman Fristoe Test of Articulation-2 (Goldman & Fristoe, 2002. Students in both service delivery models made significant improvements in speech sound production, with students in the telehealth condition demonstrating greater mastery of their Individual Education Plan (IEP goals.

    Craske, Michelle G; Waters, Allison M

    2005-01-01

    This chapter provides a review of recent empirical developments, current controversies, and areas in need of further research in relation to factors that are common as well as specific to the etiology and maintenance of panic disorder, phobias, and generalized anxiety disorder. The relative contribution of broad risk factors to these disorders is discussed, including temperament, genetics, biological influences, cognition, and familial variables. In addition, the role that specific learning experiences play in relation to each disorder is reviewed. In an overarching hierarchical model, it is proposed that generalized anxiety disorder, and to some extent panic disorder, loads most heavily on broad underlying factors, whereas specific life history contributes most strongly to circumscribed phobias.

  9. Communication disorders in individuals with cleft lip and palate: An overview

    2009-10-01

    Full Text Available The need for an interdisciplinary approach in the comprehensive management of individuals with cleft lip and palate is well recognized. This article provides an introduction to communication disorders in individuals with cleft lip and palate for members of cleft care teams. The speech pathologist is involved in identifying those infants who are at risk for communication disorders and also for initiating early intervention to prevent or mitigate communication disorders caused by the cleft. Even with early cleft repair, some children exhibit ′cleft palate speech′ characterized by atypical consonant productions, abnormal nasal resonance, abnormal nasal airflow, altered laryngeal voice quality, and nasal or facial grimaces. These manifestations are evaluated to identify those that (a are developmental, (b can be corrected through speech therapy alone, and, (c those that may require both surgery and speech therapy. Speech is evaluated perceptually using several types of stimuli. It is important to identify compensatory and obligatory errors in articulation. When velopharyngeal dysfunction is suspected, the assessment should include at least one direct measure such as nasoendoscopy or videofluoroscopy. This provides information about the adequacy of the velopharyngeal valve for speech production, and is useful for planning further management of velopharyngeal dysfunction. The basic principle of speech therapy in cleft lip and palate is to establish the correct placement of the articulators and appropriate air flow. Appropriate feedback is important during therapy for establishing the correct patterns of speech.

  12. Weak responses to auditory feedback perturbation during articulation in persons who stutter: evidence for abnormal auditory-motor transformation.

    Directory of Open Access Journals (Sweden)

    Shanqing Cai

    Full Text Available Previous empirical observations have led researchers to propose that auditory feedback (the auditory perception of self-produced sounds when speaking functions abnormally in the speech motor systems of persons who stutter (PWS. Researchers have theorized that an important neural basis of stuttering is the aberrant integration of auditory information into incipient speech motor commands. Because of the circumstantial support for these hypotheses and the differences and contradictions between them, there is a need for carefully designed experiments that directly examine auditory-motor integration during speech production in PWS. In the current study, we used real-time manipulation of auditory feedback to directly investigate whether the speech motor system of PWS utilizes auditory feedback abnormally during articulation and to characterize potential deficits of this auditory-motor integration. Twenty-one PWS and 18 fluent control participants were recruited. Using a short-latency formant-perturbation system, we examined participants' compensatory responses to unanticipated perturbation of auditory feedback of the first formant frequency during the production of the monophthong [ε]. The PWS showed compensatory responses that were qualitatively similar to the controls' and had close-to-normal latencies (∼150 ms, but the magnitudes of their responses were substantially and significantly smaller than those of the control participants (by 47% on average, p<0.05. Measurements of auditory acuity indicate that the weaker-than-normal compensatory responses in PWS were not attributable to a deficit in low-level auditory processing. These findings are consistent with the hypothesis that stuttering is associated with functional defects in the inverse models responsible for the transformation from the domain of auditory targets and auditory error information into the domain of speech motor commands.

  14. Depression and eating disorders.

    Science.gov (United States)

    Casper, R C

    1998-01-01

    Both depressive disorders and eating disorders are multidimensional and heterogeneous disorders. This paper examines the nature of their relationship by reviewing clinical descriptive, family-genetic, treatment, and biological studies that relate to the issue. The studies confirm the prominence of depressive symptoms and depressive disorders in eating disorders. Other psychiatric syndromes which occur with less frequency, such as anxiety disorders and obsessive-compulsive disorders in anorexia nervosa, or personality disorders, anxiety disorders, and substance abuse in bulimia nervosa, also play an important role in the development and maintenance of eating disorders. Since few studies have controlled for starvation-induced physical, endocrine, or psychological changes which mimic the symptoms considered diagnostic for depression, further research will be needed. The evidence for a shared etiology is not compelling for anorexia nervosa and is at most suggestive for bulimia nervosa. Since in contemporary cases dieting-induced weight loss is the principal trigger, women with self-critical or depressive features will be disproportionately recruited into eating disorders. The model that fits the data best would accommodate a relationship between eating disorders and the full spectrum of depressive disorders from no depression to severe depression, with somewhat higher rates of depression in bulimic anorectic and bulimia nervosa patients than in restricting anorexia nervosa patients, but the model would admit a specific pathophysiology and psychopathology in each eating disorder.

    Managing the violent behaviour of mentally disordered offenders (MDO) is challenging in all jurisdictions. We describe the ethical framework and practical management of MDOs in England and Wales in the context of the move to equivalence of healthcare between hospital and prison. We consider the similarities and differences between prison and hospital management of the violent and challenging behaviours of MDOs. We argue that both types of institution can learn from each other and that equivalence of care should extend to equivalence of criminal proceedings in court and prisons for MDOs. We argue that any adjudication process in prison for MDOs is enhanced by the relevant involvement of mental health professionals and the articulation of the ethical principles underpinning health and criminal justice practices.

  19. "Not all my fault": genetics, stigma, and personal responsibility for women with eating disorders.

    Easter, Michele M

    2012-10-01

    Medical researchers and clinicians increasingly understand and present eating disorders (anorexia and bulimia nervosa) as biologically-based psychiatric disorders, with genetic risk factors established by high heritability estimates in twin studies. But there has been no research on interpretation of genetic involvement by people with eating disorders, who may hold other views. Their interpretations are particularly important given the frequent presumption that biogenetic framing will reduce stigma, and recent findings that it exacerbates stigma for other mental illnesses. To identify implications of genetic framing in eating disorders, I conducted semi-structured interviews with 50 US women with a history of eating disorders (half recovered, half in treatment; interviewed 2008-9 in the USA). Interviews introduced the topic of genetics, but not stigma per se. Analysis followed the general principles of grounded theory to identify perceived implications of genetic involvement; those relevant to stigma are reported here. Most anticipated that genetic reframing would help reduce stigma from personal responsibility (i.e., blame and guilt for eating disorder as ongoing choice). A third articulated ways it could add stigma, including novel forms of stigma related to genetic-essentialist effacing of social factors. Despite welcoming reductions in blame and guilt, half also worried genetic framing could hamper recovery, by encouraging fatalistic self-fulfilling prophecies and genetic excuses. This study is the first to elicit perceptions of genetic involvement by those with eating disorders, and contributes to an emerging literature on perceptions of psychiatric genetics by people with mental illness.

    2015-02-01

    Obsessive-compulsive disorder is a common and often chronic psychiatric illness that significantly interferes with the patient´s functioning and quality of life. The disorder is characterized by excessive intrusive and inappropriate anxiety evoking thoughts as well as time consuming compulsions that cause significant impairment and distress. The symptoms are often accompanied by shame and guilt and the knowledge of the general public and professional community about the disorder is limited. Hence it is frequently misdiagnosed or diagnosed late. There are indications that the disorder is hereditary and that neurobiological processes are involved in its pathophysiology. Several psychological theories about the causes of obsessive-compulsive disorder are supported by empirical evidence. Evidence based treatment is either with serotoninergic medications or cognitive behavioral therapy, particularly a form of behavioral therapy called exposure response prevention. Better treatment options are needed because almost a third of people with obsessive-compulsive disorder respond inadequatly to treatment. In this review article two cases of obsessive-compulsive disorder are presented. The former case is a young man with typical symptoms that respond well to treatment and the latter is a middle aged lady with severe treatment resistant symptoms. She underwent stereotactic implantation of electrodes and received deep brain stimulation, which is an experimental treatment for severe obsessive-compulsive disorder that does not respond to any conventional treatment.

    Insomnia is related to an increased risk of eating disorders, while eating disorders are related to more disrupted sleep. Insomnia is also linked to poorer treatment outcomes for eating disorders. However, over the last decade, studies examining sleep and eating disorders have relied on surveys, with no objective measures of sleep for anorexia nervosa or bulimia nervosa, and only actigraphy data for binge eating disorder. Sleep disturbance is better defined for night eating syndrome, where sleep efficiency is reduced and melatonin release is delayed. Studies that include objectively measured sleep and metabolic parameters combined with psychiatric comorbidity data would help identify under what circumstances eating disorders and sleep disturbance produce an additive effect for symptom severity and for whom poor sleep would increase risk for an eating disorder. Cognitive behavior therapy for insomnia may be a helpful addition to treatment of those with both eating disorder and insomnia. PMID:27553980
