    Courseware for Observational Research (COR Version 2) is an interactive multimedia program designed to teach the foundation of the scientific method: systematic observation. COR uses digital video with interactive coding to teach basic concepts, such as creating precise operational definitions; using frequency, interval, and duration coding; developing sampling strategies; and analyzing and interpreting data. Through lessons, a case study, and laboratory exercises, it gradually scaffolds students from teacher-directed learning into self-directed learning. The newest addition to COR is a case study in which students work collaboratively, using their own observations to make recommendations about a child's disruptive behavior in an after-school program. Evaluations of the lessons showed that classes using COR received better grades on their field observations than did those using methods that are more traditional. Students' confidence and knowledge increased as they moved through each section of the program.

    Full Text Available Information systems (IS research is found in many diverse communities. This paper explores the human-dimension of human-computer interaction (HCI to present IS-design practice in the light of courseware development. Assumptions are made that online courseware provides the perfect solution for maintaining a knowledgeable, well skilled workforce. However, empirical investigations into the effectiveness of information technology (IT-induced training solutions are scarce. Contemporary research concentrates on information communications technology (ICT training tools without considering their effectiveness. This paper offers a prescriptive IS-design methodology for managing the requirements for efficient and effective courseware development. To develop the methodology, we examined the main instructional design (ID factors that affect the design of IT-induced training programs. We also examined the tension between maintaining a well-skilled workforce and effective instructional systems design (ISD practice by probing the current ID models used by courseware developers since 1990. An empirical research project, which utilized this IS-design methodology investigated the effectiveness of using IT to train government employees in introductory ethics; this was a study that operationalized the interactive effect of cognitive preference and instructional format on training performance outcomes. The data was analysed using Rasch item response theory (IRT that models the discrimination of people’s performance relative to each other’s performance and the test-items’ difficulty relative to each test-item on the same logit scale. The findings revealed that IS training solutions developed using this IS-design methodology can be adapted to provide trainees with their preferred instructional mode and facilitate cost effective eTraining outcomes.

    Science.gov (United States)

    Wolter, Bjorn Hugo Karl

    The purpose of this study was to better understand how an online, multimedia case study method influenced students' motivation, performance, and perceptions of science in collegiate level biology classes. It utilized a mix-methods design including data from pre- and post-test, student surveys, and focus group interviews to answer one primary question, did participation in the affect student performance? Two sub-questions were: (a) did participation affect persistence? and (b) did students believe it to be a good learning experience? One hundred and eight students in 5 classes from 4 campuses in the United States and Puerto Rico participated in this study during spring semester 2009. After receiving instruction on HIV, students took a 6 questions pre-test to measure their initial knowledge of both HIV and lab procedures. Participants then engaged in the Case It! learning environment, where they watched case-studies on HIV, used virtual lab tools, created an online poster of their findings, and role-played as both family members and physicians about their case. A post-test identical to the pre-test was given to students upon completion. Both were then scored using rubrics and analyzed via paired t-Tests and ANOVA. The researcher visited all 4 study sites to conduct both the focus group interviews and student surveys. Student surveys were quantified and descriptive statistics generated. Focus group interviews were video recorded, transcribed, and inductively and deductively coded. Student knowledge increased because of participation, and the majority of students said they found the Case It! project to be both a good learning experience (95%) and one that would help with future classes or careers (87%). Based on student interviews, the Case It! project did have a beneficial impact on students' intentions to persist as science majors. Many students noted that the learning environment created an overall context in which they could apply knowledge from multiple classes

    2012-01-01

    Medical Imaging is a key training component in Biomedical Engineering programs. Medical imaging education is interdisciplinary training, involving physics, mathematics, chemistry, electrical engineering, computer engineering, and applications in biology and medicine. Seeking an efficient teaching method for instructors and an effective learning environment for students has long been a goal for medical imaging education. By the support of NSF grants, we developed the medical imaging teaching software (MITS) and associated dynamic assessment tracking system (DATS). The MITS/DATS system has been applied to junior and senior medical imaging classes through a hybrid teaching model. The results show that student's learning gain improved, particularly in concept understanding and simulation project completion. The results also indicate disparities in subjective perception between junior and senior classes. Three institutions are collaborating to expand the courseware system and plan to apply it to different class settings.

    Barnett, Christopher

    Unit plenary activities are review activities used at the end of an educational unit. This thesis examined the effects of using Inspiration, a concept mapping computer program, as a plenary activity on summative assessment scores, compared the effectiveness of Inspiration to Review Worksheets/Discussion, explored the effects of Inspiration on Understanding, Knowledge and Higher Order Process, examined time on-task behaviours and plenary completion rates, and examined student perception of the effectiveness of Inspiration as a plenary with two classes of Biology 12 students. An action research methodology was applied to collect data from two senior classes. Quantitative data was collected using pre-/post-test results, time on-task behaviour, and assignment completion. Qualitative data was collected to identify student perception of the plenary and student study habits. The findings indicate that Inspiration statistically significantly improved summative scores, Understanding, Knowledge, time on-task behaviours, and plenary completion rates. The Inspiration and Review Worksheet/Discussion plenary activities were not statistically different in improving summative scores.

    1997-11-01

    Although expert problem solvers typically use pictorial representations when solving problems, novices tend to proceed from the given problem statement to a mathematical solution without first developing a visual representation of the problem. For this reason, multimedia may be an effective tool to enhance students' success at solving problems. However, merely presenting a video of motion described in a problem is not necessarily the most effective method as was found in a recent study of students' responses on Web-based homework questions. Rather, multimedia-focused problems, where data relevant to solving the problem is embedded in a video or animation, may be the best use of multimedia in problem solving. Examples of multimedia-enhanced problems and multimedia-focused problems will be demonstrated, and their differences from "traditional" problems will be highlighted. Recommendations on the use of multimedia with problem solving and preliminary data on students' success at solving these problems will be discussed.

Eight chapter were designed - guide and introduction, system tour on nuclear power plant, reactor kinetics theory, application of reactor kinetics, criticality measurement experiment, reactivity measurement, load-following operation transient, reactor operation experiment. At this point, 5 chapters were completed and 3 chapters are under construction with expectation of near-term completion. A html courseware files were operated on PC LINUX and on-line login can be done on the site 'http://cylex.kyunghee.ac.kr'. Each chapter consist of lecture note, lecture slides, self-diagnostic quiz, pass/fail exam and cyber simulator. The second task of this project was to build a cyber lecture and experiment space(CyLEX) to operate a developed courseware on it. 30 seats classroom was completed in the engineering bldg at Kyung Hee University. A advanced space - CyLEX was equipped with computers, electronic board, beam projector, digital camera OHP, etc. Courseware was loaded on the server and opened to public on 24 hour base. Another function of classroom is a capability of lecturer to monitor and command of student computers. Development on system was focused on operation for on-site lecture with intra-net. However, remote on-line class for inter-net can be open to the public under the limitation of transmission speed via internet gateways. 40 figs., 1 tabs. (Author)

    In this paper we present a mechanism to provide Quality of Service (QoS) guarantees to different multimedia applications that share link bandwidth in IP-based differential services domain. In this mechanism weights are associated with each and to individual users according to their priorities. In order to evaluate the performance of our scheme we conducted simulations. The test data used portray different multimedia applications i.e. MPEG-2, IP telephony. The simulation results obtained show the effectiveness of our scheme for multimedia applications by allocating link share to each multimedia application and minimising end-to-end transmission delay 9Y bringing them in line with the recommended standard acceptable transmission delay for multimedia applications. This paper also presents extension to our proposed Relative Bandwidth Sharing (RES) scheme for differential services. We have identified and highlighted the role of border routers and core routers in differential services domain. Exploring features of Internet Protocol IPv6 in our architecture. (author)

    2015-04-01

    The use of simulations has been considered as opportunities for students to enhance their critical thinking (CT), but previous studies were limited because they did not provide in-depth information on the working dynamics of simulation or on the effects of the number of simulation exposures on CT. This study examined the effect of an integrated pediatric nursing simulation used in a nursing practicum on students' CT abilities and identified the effects of differing numbers of simulation exposures on CT in a multi-site environment. The study used a multi-site, pre-test, post-test design. A total of 237 nursing students at three universities enrolled in a pediatric practicum participated in this study from February to December 2013. All three schools used the same simulation courseware, including the same simulation scenarios, evaluation tools, and simulation equipment. The courseware incorporated high-fidelity simulators and standardized patients. Students at school A completed one simulation session, whereas students at schools B and C completed two and three simulation sessions, respectively. Yoon's Critical Thinking Disposition tool (2008) was used to measure students' CT abilities. The gains in students' CT scores varied according to their numbers of exposures to the simulation courseware. With a single exposure, there were no statistically significant gains in CT, whereas three exposures to the courseware produced significant gains in CT. In seven subcategories of critical thinking, three exposures to the simulation courseware produced CT gains in the prudence and intellectual eagerness subcategories, and the overall simulation experience produced CT gains in the prudence, systematicity, healthy skepticism, and intellectual eagerness subcategories. Simulation courseware may produce positive learning outcomes for prudence in nursing education. In addition, the findings from the multi-site comparative study may contribute to greater understanding of how patient

    Demirjian, A; David, B

    1995-01-01

    Health professionals in various fields of Medicine and Dentistry must acquire comprehensive technological knowledge in order to practice their professions. A large portion of that knowledge cannot be found in a textbook. Examples of this type of information are data gleaned from viewing microscopic slides and dissecting cadavers. In order to fully comprehend an area of study in medicine, the student relies on various resources (often physically unrelated, like the x-ray department and the dissection room). This situation makes the teaching and learning processes much more difficult to accomplish, since the instructor and students have to manipulate multiple media and take the courses in various sites. Today's technology allows us to design and create teaching and learning tools that can alleviate these difficulties. Personal computers are now used to capture and display a vast array of information through many different media: text, sound, images, photographs, illustrations, animation and video. This information can be presented to the user with audio-visual interfaces designed to facilitate efficient communication of ideas. It is controlled primarily by the use of the mouse, at one's own pace. This interactive, multi-media approach to teaching and learning is called "Edutainment" (Education and Entertainment). This demonstration will show how these new tools are used to teach and learn about various subjects related to Medicine, particularly in Dermatology and Dentistry. Several courseware applications were developed, addressing various aspects of the field: Cancers of the Skin, Dental Development, the Temporomandibular joint, the Masticatory Muscles etc. These programs provide anthropological data on growth collected through longitudinal research, diagnosis and treatments of pigmented lesions of the skin, thousands of digitized x-rays accessible through a relational database, the latest imaging technology used to diagnose the temporomandibular disorders, high

    2010-01-01

    Digital multimedia such as images and videos are prevalent on today's internet and cause significant social impact, which can be evidenced by the proliferation of social networking sites with user generated contents. Due to the ease of generating and modifying images and videos, it is critical to establish trustworthiness for online multimedia information. In this paper, we propose novel approaches to perform multimedia forensics using compact side information to reconstruct the processing history of a document. We refer to this as FASHION, standing for Forensic hASH for informatION assurance. Based on the Radon transform and scale space theory, the proposed forensic hash is compact and can effectively estimate the parameters of geometric transforms and detect local tampering that an image may have undergone. Forensic hash is designed to answer a broader range of questions regarding the processing history of multimedia data than the simple binary decision from traditional robust image hashing, and also offers more efficient and accurate forensic analysis than multimedia forensic techniques that do not use any side information.

A list of physical/chemical/biological processes related to multimedia-based exposure and risk assessment is first presented as a basis for comparing the overall capabilities of RESRAD, MMSOILS, and MEPAS. Model design, formulation, and function are then examined by applying the models to a series of hypothetical problems. Major components of the models (e.g., atmospheric, surface water, groundwater) are evaluated separately and then studied as part of an integrated system for the assessment of a multimedia release scenario to determine effects due to linking components of the models. Seven modeling scenarios are used in the conduct of this benchmarking study: (1) direct biosphere exposure, (2) direct release to the air, (3) direct release to the vadose zone, (4) direct release to the saturated zone, (5) direct release to surface water, (6) surface water hydrology, and (7) multimedia release. Study results show that the models differ with respect to (1) environmental processes included (i.e., model features) and (2) the mathematical formulation and assumptions related to the implementation of solutions (i.e., parameterization)

  7. Children in Japan and multimedia.

    Science.gov (United States)

    Shimauchi, Y

    1999-01-01

    Many parents in Japan today are very concerned and have daily problems with their children over the following kind of issues concerning video games, multimedia, and similar devices. 1) Is children's enthusiasm for video games actually harming their growth (physically or mentally)? 2) Is there any way that video games can help children in the future? For example, will playing these games help children learn to use computers or develop their power of thought? 3) Will excessive enthusiasm for TV games undermine our basic lifestyle? Is the time they spend studying at home or playing outside actually decreasing? 4) Will the methods of communication brought about by computers, pagers, and cellular phones weaken human relations among children? 5) Will being immersed in a virtual world created by computers result in a diminished sense of reality? The causes of this uneasiness may be traced to parents' own anxieties and concerns about the exceedingly rapid growth of the "information society" of today, together with the fact that their children are directly caught up in the deluge of this information and multimedia society. The development of media has coincided with the growth of today's adults, but children are immersed in a media-filled environment from the day they are born. In Japan, there are now children who can play video games before even learning to write. No one can predict what kind of adults these children will grow to be in the future, and it is fair to say that the most parents and children in Japan are being tossed about on the waves of this information explosion. At this international symposium, we hope to hear the many views that are held around the world concerning children and multimedia.

    1999-08-01

    Multimode database systems are becoming increasingly important as organizations accumulate more multimedia data. There are few solutions that allow the information to be stored and managed efficiently. Relational systems provide features that organization rely on for their alphanumeric data. Unfortunately, these system lack facilities necessary for the handling of multimedia data - things like media integration, composition and presentation, multimedia interface and interactivity, imprecise query support, and multimedia indexing. One solution suggested for storage of multimedia data is the use of object-oriented database management system as a layer on top of the relational system. The layer adds required multimedia functionality to the capabilities provided by the relational system. A prototype solution implemented in Java uses the facilities offered by JDBC to provide connection to a large number of databases. Java Media Framework is used to present the video and audio data. Among the facilities provided are image/video/audio display/playback and extension of SQL to include multimedia operators and functions.

    Science.gov (United States)

    Vanrijssen, Erwin; Widya, Ing; Michiels, Eddie

    This paper looks into communications capabilities that are required by distributed multimedia applications to achieve relation preserving information exchange. These capabilities are derived by analyzing the notion of 'information exchange' and are embodied in communications functionalities. To emphasize the importance of the users' view, a top-down approach is applied. The revised Open Systems Interconnection (OSI) Application Layer Structure (OSI-ALS) is used to model the communications functionalities and to develop an architecture for composition of multimedia teleservices with these functionalities. This work may therefore be considered an exercise to evaluate the suitability of OSI-ALS for composition of multimedia teleservices.

  14. Multimedia and children in Turkey.

    Science.gov (United States)

    Tuncer, A M; Yalçin, S S

    1999-01-01

    Multimedia will be regarded as essential tools for children to create their new world. The effects of television on young children's life have been well studied. Television differs, however, from other media, including the movies, in its pervasive impact on children. Children spend more time watching television than any other activity except sleeping. Overall 31% of children spent at least 4 hours a day watching television during weekday and 71.7% during weekend in Turkey. Television's influence on children is a function of the length of time they spend watching and the cumulative effect of what they see. Television may be a cause as well as a solution for many serious childhood problems. Excessive viewing of television has also been linked to aggressive behavior, violence, childhood obesity. On the other hand, television may act as a socializing agent and as a learning tool if the recommendations of American Academy of Pediatrics is learned by pediatricians, parents and broadcasters. The use of home personal computers in urban residence increased from 3.2% in 1993 to 6.5% by January 1998 in Turkey. Around 20% of computer households reported owing a modem. Internet has been using only for 5 years in Turkey. Nearly 40% of computer households also used CD-ROM equipment. The percentage of schools that have a computer laboratory is only 2.64%. On the other hand, multimedia allows students to move away from a uniform education for everyone to assert individual identity, liberalize education and management. It seems likely that, within the next few years, most of the countries with substantial internet infrastructure will use the internet as the major medium for disseminating information, including information on children. To prepare students for such a world demands that educational systems make the best possible use of all knowledge and technologies currently available.

  15. An Overview of Multimedia Proxy Servers

    Directory of Open Access Journals (Sweden)

    Philip Tse

    2004-08-01

    Full Text Available This paper gives an overview of the functions of the proxy servers in accessing multimedia objects over the Internet. The proxy servers use the cache replacement policies to select the cold objects to be removed from cache to release space. They use the object partitioning methods to divide each multimedia object into cacheable and non-cacheable parts. When the client bandwidth is insufficient to receive the original object, the proxy servers convert multimedia objects into objects of lower resolution in order to adapt to the client characteristics. When multiple proxy servers are present, they may work together in a cooperative manner to further enhance the cache efficiency or in a distributed manner to evenly spread the load. In summary, proxy servers become the centre of management with respect to the delivery of multimedia objects from web servers to clients over the Internet.

    2013-01-01

    Novel processing and searching tools for the management of new multimedia documents have developed. Multimedia Information Retrieval (MMIR) is an organic system made up of Text Retrieval (TR); Visual Retrieval (VR); Video Retrieval (VDR); and Audio Retrieval (AR) systems. So that each type of digital document may be analysed and searched by the elements of language appropriate to its nature, search criteria must be extended. Such an approach is known as the Content Based Information Retrieval (CBIR), and is the core of MMIR. This novel content-based concept of information handling needs to be integrated with more traditional semantics. Multimedia Information Retrieval focuses on the tools of processing and searching applicable to the content-based management of new multimedia documents. Translated from Italian by Giles Smith, the book is divided in to two parts. Part one discusses MMIR and related theories, and puts forward new methodologies; part two reviews various experimental and operating MMIR systems, a...

    Searching useful information from unstructured medical multimedia data has been a difficult problem in information retrieval. This paper reports an effective semantic medical multimedia retrieval approach which can reflect the users' query intent. Firstly, semantic annotations will be given to the multimedia documents in the medical multimedia database. Secondly, the ontology that represented semantic information will be hidden in the head of the multimedia documents. The main innovations of this approach are cross-type retrieval support and semantic information preservation. Experimental results indicate a good precision and efficiency of our approach for medical multimedia retrieval in comparison with some traditional approaches.

    Experience with radioactive fallout, with organic contaminants and with heavy metals has amply demonstrated that cross-media transfers are common and that understanding the transport, cycling, and fate of these contaminants requires a multimedia approach. Nonetheless, pollutants with similar physical and chemical attributes may follow markedly different pathways. The frequency of exceptions to predictions based on simplistic models is also sufficient to show that direct investigation of environmental contamination is essential to confirm validity of models used for conceptualizing a problem or for control. Modeling based on multimedia premises and regulatory controls that encompass multimedia considerations are challenged by a dilemma, however. First, the development of multimedia models or regulatory frameworks represents simplification and generalization. This is true for several reasons: (1) inadequate understanding of physical and environmental factors which control specific cross-media transfer; (2) the absence of specific data on certain multimedia pollutant concentrations; (3) even the most powerful computers do not have sufficient speed and capacity to deal with the known complexities of natural systems. On the other hand, for contaminants such as mercury, it may be necessary to include great detail; the overall distribution in the environment may be less important than the rate of some minor process. With sufficient experience and good judgment of what can be ignored, the simplifications and generalizations can be made. For the present, and for the foreseeable future, however, they absolutely must be accompanied by thorough field validation and monitoring.

  9. University of Saskatchewan Radiology Courseware (USRC): an assessment of its utility for teaching diagnostic imaging in the medical school curriculum.

    Science.gov (United States)

    Burbridge, Brent; Kalra, Neil; Malin, Greg; Trinder, Krista; Pinelle, David

    2015-01-01

    We have found it very challenging to integrate images from our radiology digital imaging repository into the curriculum of our local medical school. Thus, it has been difficult to convey important knowledge related to viewing and interpreting diagnostic radiology images. We sought to determine if we could create a solution for this problem and evaluate whether students exposed to this solution were able to learn imaging concepts pertinent to medical practice. We developed University of Saskatchewan Radiology Courseware (USRC), a novel interactive web application that enables preclinical medical students to acquire image interpretation skills fundamental to clinical practice. This web application reformats content stored in Medical Imaging Resource Center teaching cases for BlackBoard Learn™, a popular learning management system. We have deployed this solution for 2 successive years in a 1st-year basic sciences medical school course at the College of Medicine, University of Saskatchewan. The "courseware" content covers both normal anatomy and common clinical pathologies in five distinct modules. We created two cohorts of learners consisting of an intervention cohort of students who had used USRC for their 1st academic year, whereas the nonintervention cohort was students who had not been exposed to this learning opportunity. To assess the learning experience of the users we designed an online questionnaire and image review quiz delivered to both of the student groups. Comparisons between the groups revealed statistically significant differences in both confidence with image interpretation and the ability to answer knowledge-based questions. Students were satisfied with the overall usability, functions, and capabilities of USRC. USRC is an innovative technology that provides integration between Medical Imaging Resource Center, a teaching solution used in radiology, and a Learning Management System.

    Full Text Available Mobile devices present the opportunity to enhance our fast-growing and globally connected society, improving user-experience through novel approaches for information dissemination through mobile communication. The research community is developing new technologies, services, and applications to enable ubiquitous environments based on mobile technology. This paper tackles several important challenges such as communication cost and device limitations for development of ubiquitous multimedia applications. And we propose a system for news delivery using a set of wireless multimedia applications. For this purpose, we have performed a case study with Apple iPhone's platform, featuring two multimedia application contexts, namely, Web and native applications. The multimedia mobile applications draw on iPhone's assets, enabling context-awareness to distribute news, improving communication efficiency and setting-up viewing optimizations, thus enhancing user-experience. The proposed system is evaluated and validated through a series of real-life experiments on real devices, with online full availability. Moreover, due to the Web application availability, the system is not restrained to Apple's iPhone platform, but can also benefit users with other devices.

    Does an online, multimedia case study influence students' performance, motivation, and perceptions of science in collegiate level biology classes, and if so, how? One hundred and eight students in 5 classes from 4 campuses in the United States and Puerto Rico participated in data collection (performance tests, surveys and focus group interviews). Pre- and post-test results increased after students participated in the learning environment (F(1, 80) = 17.256, p ≤ 0.01, η2 = 0.177). Student confidence in their knowledge also increased. During focus group interviews students reported that the project was a good learning experience (95 %), would help with future classes or careers (87 %), and stimulated student curiosity by demonstrating the application of theoretical knowledge in real-world situations (64 %). The learning environment motivated students by making material relevant, which resulted in better performance. This pedagogical tool is not instructor dependent, and is adaptable.

  17. Multimedia systems overview: the big picture

    1993-01-01

    The golden opportunities represented by multimedia systems have been recognized by many. The risk and cost involved in developing the products and the markets has led to a bonanza of unlikely consortia of strange bedfellows. The premier promoter of personal computing systems, Apple Computer, has joined forces with the dominant supplier of corporate computing, IBM, to form a multimedia technology joint venture called Kaleida. The consumer electronics world's leading promoter of free trade, Sony, has joined forces with the leader of Europe's protectionist companies, Philips, to create a consumer multimedia standard called CD-I. While still paying lip service to CD-I, Sony and Philips now appear to be going their separate ways. The software world's most profitable/fastest growing firm, Microsoft, has entered into alliances with each and every multimedia competitor to create a mish mash of product classes and defacto standards. The battle for Multimedia Standards is being fought on all fronts: on standards committees, in corporate strategic marketing meetings, within industry associations, in computer retail stores, and on the streets. Early attempts to set proprietary defacto standards were fought back, but the proprietary efforts continue with renewed vigor. Standards committees were, as always, slow to define specifications, but the official standards are now known nd being implemented; ... but the proprietary efforts continue with renewed vigor. Ultimately, the buyers will decide -- like it or not. Success by the efforts to establish proprietary defacto standards could prove to be a boon to the highly creative and inventive U.S. firms, but at the cost of higher prices for consumers and slower market growth. Success by the official standards could bring lower prices for consumers and fast market growth, but force the higher-wage/higher-overhead U.S. firms to compete on a level playing field. As is always the case, you can't have your cake and eat it too.

    Full Text Available In the past few years considerable demand for business oriented multimedia information systems has developed. A multimedia information system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full-motion video, and text information. Multimedia information systems play a central role in many business activities. They represent a very special class complex computing systems. This paper surveys a special type of multimedia information systems: multimedia news systems. Multimedia news systems deal with architectures to manage complex multimedia news databases, online presentation and distribution services or the integration of several existing services to meta-services using intelligent news retrieval engines. The leading presentation platform in multimedia news presentation is news networks providing television services and Internet content distribution. The primary focus is on advanced multimedia news systems infrastructure, document standards, application architecture and principles for multimedia news on the Web that suggest long-term trends in this increasingly important area.

    Full Text Available There is a growing gap between the multimedia production and the context centric multimedia services. The main problem is the under-exploitation of the content creation design. The idea is to support dynamic content generation adapted to the user or display profile. Our work is an implementation of a web platform for automatic generation of multimedia presentations based on SMIL (Synchronized Multimedia Integration Language standard. The system is able to produce rich media with dynamic multimedia content retrieved automatically from different content databases matching the semantic context. For this purpose, we extend the standard interpretation of SMIL tags in order to accomplish a semantic translation of multimedia objects in database queries. This permits services to take benefit of production process to create customized content enhanced with real time information fed from databases. The described system has been successfully deployed to create advanced context centric weather forecasts.

    Full Text Available The dramatic increase in both computational power, brought on by the introduction of increasingly powerful chips, and the communications bandwidth, unleashed by the introduction of cable modem and ADSL, lays a solid foundation for the take-off of multimedia applications. Standards always play an important role in multimedia applications due to the need for wide distribution of multimedia contents. Standards have long played pivotal roles in the development of multimedia equipment and contents. MPEG4 and JPEG2000 are two recent multimedia standards under development under the auspice of the International Standards Organization (ISO. These new standards introduce new technology and new features that will become enabling technology for many emerging applications. In this paper, we describe the new trends and new developments that shape these new standards, and illustrate the potential impact of these new standards on multimedia applications.

    International Nuclear Information System (INIS)

    Munoz Garcia, M.

    1995-01-01

    For managing physical safety systems in nuclear power plants sophisticated computer equipment is essential. Standard safety procedure requires systems distributed throughout the plant, especially at security posts: Entrance Door, Access Control Center, Restricted Areas, etc. Besides being highly distributed, computerized physical safety management systems have always been characterized by the need to integrate very different elements. Graphic images have always played a very important role: photographs, fingerprints, signatures, etc. This makes integrated multimedia modules the ideal solution. This presentation describes how safety systems can combine not only still images, but also other multimedia data such as sound and video. It examines methodologies for using this new technology to upgrade high cost computer systems already in operation that can not be replaced. (Author)

    Wu, Chung-Ping; Kuo, C.-C. Jay

    2001-08-01

    Efficient encryption algorithms are essential to multimedia data security, since the data size is large and real-time processing is often required. After discussing limitations of previous work on multimedia encryption, we propose a novel methodology for confidentiality, which turns entropy coders into encryption ciphers by using multiple statistical models. The choice of statistical models and the order in which they are applied are kept secret as the key Two encryption schemes are constructed by applying this methodology to the Huffman coder and the QM coder. It is shown that security is achieved without sacrificing the compression performance and the computational speed. The schemes can be applied to most modern compression systems such as MPEG audio, MPEG video and JPEG/JPEG2000 image compression.

    Full Text Available With this essay, I want to understand why interactive and relational media forms have become so ubiquitous so quickly. Comparing the nexus of cinema and nationalism with the contemporary dyad of digital media and transnationalism (or globalisation, we can ask whether digital multimedia systems have arisen to reflect and impel our contemporary psychic and social conditions. Because multimedia rarely gets ‘locked-off’, its component elements can always be pulled apart, sent back to their databases and then instantaneously rearranged into newly iterated federations. In this respect it is like our unstable contemporary lives, so buffeted with ever-altering values, opportunities, anxieties and obligations all upwelling because of globalisation, migration and multiculturalism.

    2000-01-01

    Full Text Available There is at present a worldwide effort to develop next-generation wireless communication systems. It is envisioned that many of the future wireless systems will incorporate considerable signal-processing intelligence in order to provide advanced services such as multimedia transmission. In general, wireless channels can be very hostile media through which to communicate, due to substantial physical impediments, primarily radio-frequency interference and time-arying nature of the channel. The need of providing universal wireless access at high data-rate (which is the aim of many merging wireless applications presents a major technical challenge, and meeting this challenge necessitates the development of advanced signal processing techniques for multiple-access communications in non-stationary interference-rich environments. In this paper, we present some key advanced signal processing methodologies that have been developed in recent years for interference suppression in wireless networks. We will focus primarily on the problem of jointly suppressing multiple-access interference (MAI and intersymbol interference (ISI, which are the limiting sources of interference for the high data-rate wireless systems being proposed for many emerging application areas, such as wireless multimedia. We first present a signal subspace approach to blind joint suppression of MAI and ISI. We then discuss a powerful iterative technique for joint interference suppression and decoding, so-called Turbo multiuser detection, that is especially useful for wireless multimedia packet communications. We also discuss space-time processing methods that employ multiple antennas for interference rejection and signal enhancement. Finally, we touch briefly on the problems of suppressing narrowband interference and impulsive ambient noise, two other sources of radio-frequency interference present in wireless multimedia networks.

  11. Efficient Access Control in Multimedia Social Networks

    Science.gov (United States)

    Sachan, Amit; Emmanuel, Sabu

    Multimedia social networks (MMSNs) have provided a convenient way to share multimedia contents such as images, videos, blogs, etc. Contents shared by a person can be easily accessed by anybody else over the Internet. However, due to various privacy, security, and legal concerns people often want to selectively share the contents only with their friends, family, colleagues, etc. Access control mechanisms play an important role in this situation. With access control mechanisms one can decide the persons who can access a shared content and who cannot. But continuously growing content uploads and accesses, fine grained access control requirements (e.g. different access control parameters for different parts in a picture), and specific access control requirements for multimedia contents can make the time complexity of access control to be very large. So, it is important to study an efficient access control mechanism suitable for MMSNs. In this chapter we present an efficient bit-vector transform based access control mechanism for MMSNs. The proposed approach is also compatible with other requirements of MMSNs, such as access rights modification, content deletion, etc. Mathematical analysis and experimental results show the effectiveness and efficiency of our proposed approach.

The course presented trends in technological development and the achievements of Taiwanese industries and research institutes from a historical perspective, and overviewed the technology industries and industrial transformation development in Taiwan. The course units adopted multimedia to support class teaching and student learning, and a survey was conducted to collect students’ attitudes and perception toward multimedia-assisted instruction and learning in the course. Research data were collected from 45 male and 9 female students with varied academic and cultural backgrounds. Results showed that multimedia videos help raise students’ awareness of learning issues, improve their understanding of content, and increase the depth of their learning. Almost all students liked the approach of using multimedia to assist teaching and learning, preferring this approach over traditional lecture-based instruction. They also would recommend this course to their peers. This study also found that the degree of students’ engagement caused variance in the students’ perception of multimedia helpfulness in assisting their learning. Finally, this study further proposes suggestions in both design and research on applications of multimedia-enhanced learning in engineering and technology education.

    Coughlan, Jane; Morar, Sonali S

    2008-09-01

    Educational multimedia has been designed to provide surgical trainees with expert operative information outside of the operating theater. The effectiveness of multimedia (e.g., CD-ROMs) for learning has been a common research topic since the 1990s. To date, however, little discussion has taken place on the mechanisms to evaluate the quality of multimedia-driven teaching. This may be because of a lack of research into the development of appropriate tools for evaluating multimedia, especially for surgical education. This paper reports on a small-scale pilot and exploratory study (n = 12) that developed a tool for surgical multimedia evaluation. The validity of the developed tool was established through adaptation of an existing tool, which was reviewed using experts in surgery, usability, and education. The reliability of the developed tool was tested with surgical trainees who used it to assess a multimedia CD-ROM created for teaching basic surgical skills. The findings contribute to an understanding of surgical trainees' experience of using educational multimedia, in terms of characteristics of the learning material for interface design and content and the process of developing evaluation tools, in terms of inclusion of appropriate assessment criteria. The increasing use of multimedia in medical education necessitates the development of standardized tools for determining the quality of teaching and learning. Little research exists into the development of such tools and so the present work stimulates discussion on how to evaluate surgical training.

    1998-01-01

    In an environment of increasing economic constraint, it is necessary for nurse educators to design and implement cost-effective teaching and learning strategies. Computer-based interactive multimedia applications in education have been touted as a cost- and time-effective method of providing a dynamic, information rich, learning environment. Given the profusion of this type of media in the general marketplace, an increasing number of educators are now wishing to develop specific computerized multimedia applications for use in nurse education. Accounts of a number of such developments exist in the literature. However, there is a dearth of literature outlining the processes involved in interactive multimedia production. It would, therefore, appear timely to address issues related to multimedia development. Based on the author's experiences, this article will offer a number of practical suggestions for the development of interactive multimedia applications in nursing education.

    Moore, David E.; Ahmed, Farid

    2003-09-01

    In this paper we address the reliable transmission of security-enabled multimedia data over the internet which is becoming increasingly vulnerable to a variety of cyber-attacks. Due to their real-timeliness aspect, multimedia data in Internet mostly uses User Datagram Protocol(UDP) as the transport media as opposed to the Transport Control Protocol (TCP). UDP is inherently an unreliable transport media that results in certain unacknowledged packet losses. Multimedia applications usually can tolerate some packet losses for its rendering at the receiver side. But, for the security-enhanced multimedia that we are talking about, reliability of reception of most of the packets within a certain tolerance time need to be guaranteed. This is where we come in with a new protocol that ensures packet-level reliability as well as stream-level authentication of multimedia.

    Full Text Available Multimedia technology is restructuring the field of communication in various ways. The prevalent nature of this new media invites flexibility which can make communication curricula accommodate a wide range of competencies including technical competency. I have argued in this paper that multimedia, much like printing, radio, television and film, is mainly the means whereby content is delivered. Central to multimedia are content and effects. Content requires perspective which can then be reproduced in texts and images, while effects involves assessment of the influence of multimedia on society and culture. As such, multimedia needs to be approached from a mass communication perspective which preserves the identity of the field and provides a vital link between theory and practical application.

    Full Text Available The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML page using AJAX (Asynchronous JavaScript and XML, with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: “Table”, “Folder”, and “Tile” functions. PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

    The advance of web-based technology has stimulated innovation in education. This paper discusses the development and evaluation of an online multimedia resource for undergraduate-level behavioral neuroscience education. This resource surveys four major subject areas: language, attention and perception, thinking, and autism. It employs audio and video streaming, online demonstration experiments, computer simulation, and internet links. This online resource has two distinct advantages over a paper textbook. First, a considerable proportion of the content is conveyed using multimedia, thus making the learning experience more vivid and dynamic. Second, its interactive components provide opportunities for students to participate in the various experimental tasks introduced in the text and to compare their own performance with those of others. This hands-on experience not only enables students to gain in-depth procedural knowledge of the tasks but also has positive effects on their motivation. Feedback from three undergraduate classes that used this resource as supplementary material showed that students were highly positive about its pedagogical values. This free resource is available on the web at http://psych.rice.edu/mmtbn/.

    Over the past decade, the US Department of Energy (DOE) and other agencies have faced increasing scrutiny for a wide range of environmental issues related to past and current practices. A number of large-scale applications have been undertaken that required analysis of large numbers of potential environmental issues over a wide range of environmental conditions and contaminants. Several of these applications, referred to here as large-scale applications, have addressed long-term public health risks using a holistic approach for assessing impacts from potential waterborne and airborne transport pathways. Multimedia models such as the Multimedia Environmental Pollutant Assessment System (MEPAS) were designed for use in such applications. MEPAS integrates radioactive and hazardous contaminants impact computations for major exposure routes via air, surface water, ground water, and overland flow transport. A number of large-scale applications of MEPAS have been conducted to assess various endpoints for environmental and human health impacts. These applications are described in terms of lessons learned in the development of an effective approach for large-scale applications

    The computer-based learning methods in medicine have been well established as stand-alone learning systems. Recently, these systems were enriched with the use of telematics technology to provide distance learning capabilities. Stereotactic radiotherapy is more of the most representative advanced radiotherapy techniques. Due to the multidisciplinary character of the technique and the rapid evolution of technology implemented, the demands in training have increased. The potential of interactive multimedia and Internet technologies for the achievement of distance learning capabilities in this domain are investigated. The realization of a computer-based educational program in stereotactic radiotherapy in a multimedia format is a new application in the computer-aided distance learning field. The system is built according to a client and server architecture, based on the Internet infrastructure, and composed of server nodes. The impact of the system may be described in terms of: time and transportation costs saving, flexibility in training (scheduling, rate and subject selection), online communication and interaction with experts, cost effective access to material (delivery or access by a large number of users and revision of the material by avoiding and database development.

    Full Text Available Multimedia communications are communications with several types of media, such as audio, video and data. The current Internet has some levels of capability to support multimedia communications, unfortunately, the QoS (Quality of Service is still challenging. A large number of QoS mechanisms has been proposed; however, the main concern is for low levels, e.g. layer 2 (Data Link or 3 (Transport. In this paper, mechanisms for control the quality of audio and video are proposed. G.723.1 and MPEG-4 are used as the audio and video codec respectively. The proposed algorithm for adaptive quality control of audio communication is based on forward error correction (FEC. In the case of video communication, the proposed algorithm adapts the value of key frame interval, which is an encoding parameter of MPEG-4. We evaluated our proposed algorithms by computer simulation. We have shown that, in most cases, the proposed scheme gained a higher throughput compared to other schemes.

    2013-03-01

    Search and retrieval of huge archives of Multimedia data is a challenging task. A classification step is often used to reduce the number of entries on which to perform the subsequent search. In particular, when new entries of the database are continuously added, a fast classification based on simple threshold evaluation is desirable. In this work we present a CART-based (Classification And Regression Tree [1]) classification framework for audio streams belonging to multimedia databases. The database considered is the Archive of Ethnography and Social History (AESS) [2], which is mainly composed of popular songs and other audio records describing the popular traditions handed down generation by generation, such as traditional fairs, and customs. The peculiarities of this database are that it is continuously updated; the audio recordings are acquired in unconstrained environment; and for the non-expert human user is difficult to create the ground truth labels. In our experiments, half of all the available audio files have been randomly extracted and used as training set. The remaining ones have been used as test set. The classifier has been trained to distinguish among three different classes: speech, music, and song. All the audio files in the dataset have been previously manually labeled into the three classes above defined by domain experts.

    Martinez, Izacar; Grifoll, Jordi; Giralt, Francesc; Rallo, Robert

    2010-01-01

    The prospect of assessing the environmental distribution of chemicals directly from their molecular information was analyzed. Multimedia chemical partitioning of 455 chemicals, expressed in dimensionless compartmental mass ratios, was predicted by SimpleBox 3, a Level III Fugacity model, together with the propagation of reported uncertainty for key physicochemical and transport properties, and degradation rates. Chemicals, some registered in priority lists, were selected according to the availability of experimental property data to minimize the influence of predicted information in model development. Chemicals were emitted in air or water in a fixed geographical scenario representing the Netherlands and characterized by five compartments (air, water, sediments, soil and vegetation). Quantitative structure-fate relationship (QSFR) models to predict mass ratios in different compartments were developed with support vector regression algorithms. A set of molecular descriptors, including the molecular weight and 38 counts of molecular constituents were adopted to characterize the chemical space. Out of the 455 chemicals, 375 were used for training and testing the QSFR models, while 80 were excluded from model development and were used as an external validation set. Training and test chemicals were selected and the domain of applicability (DOA) of the QSFRs established by means of self-organizing maps according to structural similarity. Best results were obtained with QSFR models developed for chemicals belonging to either the class [C] and [C; O], or the class with at least one heteroatom different than oxygen in the structure. These two class-specific models, with respectively 146 and 229 chemicals, showed a predictive squared coefficient of q 2 ≥ 0.90 both for air and water, which respectively dropped to q 2 ∼ 0.70 and 0.40 for outlying chemicals. Prediction errors were of the same order of magnitude as the deviations associated to the uncertainty of the

    2001-10-01

    In this work, our aim is to provide finer priority levels in the design of a general-purpose Web multimedia server with provisions of the CM services. The type of services provided include reading/writing a web page, downloading/uploading an audio/video stream, navigating the Web through browsing, and interactive video teleconferencing. The selected priority encoding levels for such operations follow the order of admin read/write, hot page CM and Web multicasting, CM read, Web read, CM write and Web write. Hot pages are the most requested CM streams (e.g., the newest movies, video clips, and HDTV channels) and Web pages (e.g., portal pages of the commercial Internet search engines). Maintaining a list of these hot Web pages and CM streams in a content addressable buffer enables a server to multicast hot streams with lower latency and higher system throughput. Cold Web pages and CM streams are treated as regular Web and CM requests. Interactive CM operations such as pause (P), resume (R), fast-forward (FF), and rewind (RW) have to be executed without allocation of extra resources. The proposed multimedia server model is a part of the distributed network with load balancing schedulers. The SM is connected to an integrated disk scheduler (IDS), which supervises an allocated disk manager. The IDS follows the same priority handling as the SM, and implements a SCAN disk-scheduling method for an improved disk access and a higher throughput. Different disks are used for the Web and CM services in order to meet the QoS requirements of CM services. The IDS ouput is forwarded to an Integrated Transmission Scheduler (ITS). The ITS creates a priority ordered buffering of the retrieved Web pages and CM data streams that are fed into an auto regressive moving average (ARMA) based traffic shaping circuitry before being transmitted through the network.

  7. Efficient multimedia distribution framework for Internet video

    Yao, Jia; Vass, Jozsef; Huang, Yan; Zhuang, Xinhua

    2000-04-01

    Multimedia distribution over the Internet is becoming increasingly popular. Since the Internet was designed for computer data communication, satisfying the different characteristics and requirements of multimedia streams poses significant challenges. For effective and efficient Internet video streaming, many issues (e.g., multiresolution representation, multicast transmission, error control, synchronization, etc.) must be addressed. In the paper, a novel framework for Internet video streaming is proposed. For video compression, our previously developed three-dimensional significance-linked connected component analysis (3D-SLCCA) codec is applied. 3D-SLCCA provides high coding efficiency, multiresolution video representation, transmission error resilience, and low computational complexity. For audio coding, the GSM standard is used. For error control, retransmission and error concealment are jointly applied. Multiresolution-multicast transmission is implemented by assigning different multicast group addresses to different video layers. Thus each receiver subscribes to the maximum number of layers that both its hardware resource and network capability can handle. By using hierarchically structured multicast tree, each node is responsible for caching packets, collecting NACK packets, and sending repair packets. This not only significantly reduces the latency, but also efficiently solves the 'ACK implosion' problem. As opposed to data transmission, reliable multicast is not required by the network infrastructure. Based on timing constraint and importance of lost packets, each receiver decides whether to ask for retransmission or apply error concealment. Finally synchronization is accomplished by using the timestamp mechanism of RTP. When the network does not support multicasting, proxy servers implemented on workstations can be used to perform similar functionalities.

The basic ideal of JBCC is that the jitter-corrupted multimedia packets are useless to the client and it is a waste of network resources to continue to forward these packets in the networks. JBCC improves the QoS of multimedia stream in Metro Ethernet Network by detecting and discarding packets that accumulated enough jitter so as to maintain a high bandwidth for packets that stay within the multimedia stream's jitter tolerance. Simulation results have shown that the proposed scheme can effectively lower the average received packet jitter than that using traditional congestion control algorithm RED and DropTail. Moreover, the proposed scheme can improve the useful goodput of the received packets when compared to RED and DropTail.

    The U.S. Geological Survey (USGS) is the primary U.S. Government agency for water data collection and dissemination. In this role, the USGS has recently created and deployed a National Water Census Data Portal (NWC-DP) which provides access to streamflow, evapotransporation, precipitation, aquatic biology and other data at the national level. Recognizing the value of these data sets for hydrologic science education, this paper presents an effort to bridge the gap between pencil–and-paper-based hydrology curriculum and the USGS NWC-DP resource. Specifically, we have developed an R package, National Water Census Education (NWCEd), and five associated laboratory exercises that integrate R- and web-services-based access to the NWC-DP data sets. Using custom functions built into the NWCEd, students are able to access unprecedented amounts of hydrologic data from the NWC-DP, which can be applied to current hydrology curriculum and analyzed using NWCEd and a number of other open-source R tools.

    Multimedia is often utilized by teachers to present a learning materials. Learning that delivered by multimedia enables people to understand the information of up to 60% of the learning in general. To applying the creative learning to the classroom, multimedia presentation needs a laboratory as a space that provides multimedia needs. This study aims to reveal the level of student acceptance on the multimedia laboratories, by explaining the direct and indirect effect of internal support and technology infrastructure. Technology Acceptance Model (TAM) is used as the basis of measurement on this research, through the perception of usefulness, ease of use, and the intention, it’s recognized capable of predicting user acceptance about technology. This study used the quantitative method. The data analysis using path analysis that focuses on trimming models, it’s performed to improve the model of path analysis structure by removing exogenous variables that have insignificant path coefficients. The result stated that Internal Support and Technology Infrastructure are well mediated by TAM variables to measure the level of technology acceptance. The implications suggest that TAM can measure the success of multimedia laboratory utilization in Faculty of Engineering UNIMA.

    Full Text Available Cognitive theory of Multimedia learning has been a widely used principle in education. However, with current technological advancements and usage, the teaching and learning trend of children’s have also changed with more dependability towards technology. This research work explores and implement the use of 3D Animation as tool for multimedia learning based on cognitive theory. This new dimension in cognitive learning, will foster the latest multimedia tools and application driven through 3D Animation, Virtual Reality and Augmented Reality. The three principles, that facilitate cognitive theory of multimedia learning using animation, addressed in this research are temporal contiguity principle (screening matching narration with animation simultaneously rather than successively, personalization principle (screening text or dialogs in casual form rather than formal style and finally the multimedia principle (screen animation and audio narration together instead of just narration. The result of this new model would yield a new technique of educating the young children through 3D animation and virtual reality. The adaptation of  cognitive theory through 3D animation as a source of multimedia learning with various key principles produces a reliable paradigm for educational enhancement.

    Muddam, Sandeep Reddy

    The abstract mainly focuses on describing the prototype of the "GIS Multimedia View of Local Politics" of San Diego County. This project puts the local political information on a website which helps school children to learn about the structure of a political body and how it is organized, how the representatives are elected. It also puts up the statistics of the elections previously held. So for this, past and present election statistics have been collected. The shape files of San Diego county, congressional districts, council districts, supervisor districts have been collected. A sample community college districts is also presented. With these shape files we can show the information in an interactive map application which is based on GIS. Poll Watcher: A candidate, political party or political committee may ask someone to go to a polling place or early voting area and observe. This person is known as a poll watcher. The poll watcher observes the election process to see if any violation of the election laws occurs. If a violation occurs, the poll watcher is to refer the violation to the clerk of the election board.

    Mourning the death of a beloved person is one of life's most stressful events. This psychotherapy case study describes a form of psychodynamic psychotherapy that the author developed in working with a patient who suffered from complicated grief after the death of her father from lung cancer. During sessions, the therapist worked with the patient to collect pictures and organize a "strip of life" of her father's most meaningful moments. The patient then wrote a short text associated with each picture. Finally, she chose music to be added to this "slide show" or "psychodynamic montage" as its soundtrack. The resulting multimedia presentation was finally posted on the Internet on a website to which only the patient and her relatives and friends had access via a password. This therapeutic strategy was effective in helping this patient resolve her symptoms of complicated grief. The author suggests that this new approach to psychodynamic psychotherapy may be a cost-effective and well-received tool for use in institutions such as hospices and general hospitals.

    2007-01-01

    Full Text Available With an ever increasing penetration of Internet Protocol (IP technologies, the wireless industry is evolving the mobile core network towards all-IP network. The IP Multimedia Subsystem (IMS is a standardised Next Generation Network (NGN architectural framework defined by the 3rd Generation Partnership Project (3GPP to bridge the gap between circuit-switched and packet-switched networks and consolidate both sides into on single all-IP network for all services. In this paper, we provide an insight into the limitation of the presence service, one of the fundamental building blocks of the IMS. Our prototype-based study is unique of its kind and helps identifying the factors which limit the scalability of the current version of the presence service (3GPP TS 23.141 version 7.2.0 Release 7 [1], which will in turn dramatically limit the performance of advanced IMS services. We argue that the client-server paradigm behind the current IMS architecture does not suite the requirements of the IMS system, which defies the very purpose of its introduction. We finally elaborate on possible avenues for addressing this problem.

    Full Text Available Wireless Ad hoc networks provide a flexible and adaptable infrastructure to transport data over a great variety of environments. Recently, real-time audio and video data transmission has been increased due to the appearance of many multimedia applications. One of the major challenges is to ensure the quality of multimedia streams when they have passed through a wireless ad hoc network. It requires adapting the network architecture to the multimedia QoS requirements. In this paper we propose a new architecture to organize and manage cluster-based ad hoc networks in order to provide multimedia streams. Proposed architecture adapts the network wireless topology in order to improve the quality of audio and video transmissions. In order to achieve this goal, the architecture uses some information such as each node’s capacity and the QoS parameters (bandwidth, delay, jitter, and packet loss. The architecture splits the network into clusters which are specialized in specific multimedia traffic. The real system performance study provided at the end of the paper will demonstrate the feasibility of the proposal.

    2016-06-01

    Education on the subject of groundwater is crucial for sustainability. Nevertheless, international studies with students across different age groups have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Drawing from international research, a multimedia learning program Zwischen Regenwolke und Wasserhahn (between the rain cloud and the tap) was developed, which incorporates specific insights from the fields of conceptual change research, multimedia research, and the model of educational reconstruction. The effectiveness of the learning program was ascertained by means of two studies with Austrian seventh grade pupils as well as teacher-training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge of groundwater were determined in a pre- and post-test. The pupils and students greatly benefitted from working through the learning software independently. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results indicate that theory-guided multimedia learning programs can play an important role in the transfer of research results to classroom settings, especially in science education.

    Full Text Available Multimedia services over mobile device-to-device (D2D networks has recently received considerable attention. In this scenario, each device is equipped with a cellular communication interface, as well as a D2D interface over a shared medium. In this work, we study the performance properties of the mobile D2D communications in the framework of user satisfaction, and develop a fully distributed QoE-aware multimedia communication scheme (QAMCS. Specifically, we translate the opportunistic multimedia communications issue into a stochastic optimization problem, which opens up a new degree of performance to exploit. Moreover, QAMCS is designed for a heterogeneous and dynamic environment, in which user demand, device mobility, and transmission fashion may vary across different devices and applications. Importantly, QAMCS is able to maximize the user satisfaction and only needs each device to implement its own scheme individually in the absence of a central controller.

    Full Text Available In interactive multimedia environments, different digital elements (i. e. video, audio, visuals, text, animations, graphics and glossary can be combined and delivered on the same digital computer screen (TDM 1997: 151, CCED 1987, Brett 1998: 81, Stenton 1998: 11, Mangiafico 1996: 46. This also enables effectively provision and presentation of feedback in pedagogically more efficient ways, which meets not only the requirement of different teaching and learning theories, but also the needs of language learners who vary in their learning-style preferences (Robinson 1991: 156, Peter 1994: 157f.. This study aims to bring out the pedagogical and design principles that might help us to more effectively design and customise feedback in interactive multimedia language learning environments. While so doing, some examples of thought out and customized computerised feedback from an interactive multimedia language learning environment, which were designed and created by the author of this study and were also used for language learning purposes, will be shown.

  11. Secure and Reliable IPTV Multimedia Transmission Using Forward Error Correction

    2012-01-01

    Full Text Available With the wide deployment of Internet Protocol (IP infrastructure and rapid development of digital technologies, Internet Protocol Television (IPTV has emerged as one of the major multimedia access techniques. A general IPTV transmission system employs both encryption and forward error correction (FEC to provide the authorized subscriber with a high-quality perceptual experience. This two-layer processing, however, complicates the system design in terms of computational cost and management cost. In this paper, we propose a novel FEC scheme to ensure the secure and reliable transmission for IPTV multimedia content and services. The proposed secure FEC utilizes the characteristics of FEC including the FEC-encoded redundancies and the limitation of error correction capacity to protect the multimedia packets against the malicious attacks and data transmission errors/losses. Experimental results demonstrate that the proposed scheme obtains similar performance compared with the joint encryption and FEC scheme.

  17. Bandwidth Estimation in Wireless Lans for Multimedia Streaming Services

    Directory of Open Access Journals (Sweden)

    Heung Ki Lee

    2007-01-01

    Full Text Available The popularity of multimedia streaming services via wireless networks presents major challenges in the management of network bandwidth. One challenge is to quickly and precisely estimate the available bandwidth for the decision of streaming rates of layered and scalable multimedia services. Previous studies based on wired networks are too burdensome to be applied to multimedia applications in wireless networks. In this paper, a new method, IdleGap, is suggested to estimate the available bandwidth of a wireless LAN based on the information from a low layer in the protocol stack. We use a network simulation tool, NS-2, to evaluate our new method with various ranges of cross-traffic and observation times. Our simulation results show that IdleGap accurately estimates the available bandwidth for all ranges of cross-traffic (100 Kbps ∼ 1 Mbps with a very short observation time of 10 seconds.

  18. 3D Integration for Wireless Multimedia

    Kimmich, Georg

    The convergence of mobile phone, internet, mapping, gaming and office automation tools with high quality video and still imaging capture capability is becoming a strong market trend for portable devices. High-density video encode and decode, 3D graphics for gaming, increased application-software complexity and ultra-high-bandwidth 4G modem technologies are driving the CPU performance and memory bandwidth requirements close to the PC segment. These portable multimedia devices are battery operated, which requires the deployment of new low-power-optimized silicon process technologies and ultra-low-power design techniques at system, architecture and device level. Mobile devices also need to comply with stringent silicon-area and package-volume constraints. As for all consumer devices, low production cost and fast time-to-volume production is key for success. This chapter shows how 3D architectures can bring a possible breakthrough to meet the conflicting power, performance and area constraints. Multiple 3D die-stacking partitioning strategies are described and analyzed on their potential to improve the overall system power, performance and cost for specific application scenarios. Requirements and maturity of the basic process-technology bricks including through-silicon via (TSV) and die-to-die attachment techniques are reviewed. Finally, we highlight new challenges which will arise with 3D stacking and an outlook on how they may be addressed: Higher power density will require thermal design considerations, new EDA tools will need to be developed to cope with the integration of heterogeneous technologies and to guarantee signal and power integrity across the die stack. The silicon/wafer test strategies have to be adapted to handle high-density IO arrays, ultra-thin wafers and provide built-in self-test of attached memories. New standards and business models have to be developed to allow cost-efficient assembly and testing of devices from different silicon and technology

    Ever emerging applications in handheld multimedia devices such as mobile phones, laptop computers, portable video games and digital cameras requiring increased screen resolutions are driving higher aggregate bitrates between host processor and display(s) enabling services such as mobile video conferencing, video on demand and TV broadcasting. Larger displays and smaller phones require complex mechanical 3D hinge configurations striving to combine maximum functionality with compact building volumes. Conventional galvanic interconnections such as Micro-Coax and FPC carrying parallel digital data between host processor and display module may produce Electromagnetic Interference (EMI) and bandwidth limitations caused by small cable size and tight cable bends. To reduce the number of signals through a hinge, the mobile phone industry, organized in the MIPI (Mobile Industry Processor Interface) alliance, is currently defining an electrical interface transmitting serialized digital data at speeds >1Gbps. This interface allows for electrical or optical interconnects. Above 1Gbps optical links may offer a cost effective alternative because of their flexibility, increased bandwidth and immunity to EMI. This paper describes the development of optical links for handheld communication devices. A cable assembly based on a special Plastic Optical Fiber (POF) selected for its mechanical durability is terminated with a small form factor molded lens assembly which interfaces between an 850nm VCSEL transmitter and a receiving device on the printed circuit board of the display module. A statistical approach based on a Lean Design For Six Sigma (LDFSS) roadmap for new product development tries to find an optimum link definition which will be robust and low cost meeting the power consumption requirements appropriate for battery operated systems.

    Identifying disability early in life confers long-term benefits for children. The Taipei City Child Development Screening tool, second version (Taipei II) provides checklists for 13 child age groups from 4 months to 6 years. However, the usability of a text-based screening tool largely depends on the literacy level and logical reasoning ability of the caregivers, as well as language barriers caused by increasing numbers of immigrants. The objectives of this study were to (1) design and develop a Web-based multimedia version of the current Taipei II developmental screening tool, and (2) investigate the measurement equivalence of this multimedia version to the original paper-based version. To develop the multimedia version of Taipei II, a team of experts created illustrations, translations, and dubbing of the original checklists. The developmental screening test was administered to a total of 390 primary caregivers of children aged between 4 months and 6 years. Psychometric testing revealed excellent agreement between the paper and multimedia versions of Taipei II. Good to excellent reliabilities were demonstrated for all age groups for both the cross-mode similarity (mode intraclass correlation range 0.85-0.96) and the test-retest reliability (r=.93). Regarding the usability, the mean score was 4.80 (SD 0.03), indicating that users were satisfied with their multimedia website experience. The multimedia tool produced essentially equivalent results to the paper-based tool. In addition, it had numerous advantages, such as it can facilitate active participation and promote early screening of target populations.

    Gaudio, Alejandra; De Ponti, Javier

    2002-06-01

    Great technological advances can help us to recover communication areas that might otherwise be lost. Media competition and visual contamination frequently appear in daily communication. A notable anonymity in human relationship has emerged as a consequence of this. Educational establishments receive an overflowing number of students. Schools and students are overwhelmed by this situation. Teachers don't know their students and students usually don't know their own classmates, with all the consequences that this implies. In front of this inadequate structure of educational institutions, technology has improved the possibilities of instant answers and the dialogue between teachers and students; the unilateral exposition pronounced by teachers in front of the anonymous mass finds an alternative in multimedia systems. The present work describes Interactive Multimedia System's utilization for teaching the chromatic circle as a system of color organization. The proposed method intends to devise a theoretical and conceptual frame and its production for multimedia systems oriented to elaborate, represent, store, interact with and access to knowledge Its relevance comes from the potential contribution to build up knowledge systems that value cultural codes and at the same time make creative and motivating interactive experiences. This work concerns the realization and understanding of the chromatic circle, selection of different color systems, logical strategies for playing and studying theory and multimedia. Levels of visualization: theory, practice, developing skills, works and evaluation. Levels to study: teaching chromatic circle, multimedia supports, quality, application and linking screens, help, theory, etc; without losing the interdisciplinary nature of the work, specialist participation, and Multimedia Systems in the steps of its realization.

    Full text: The popularity of computer multimedia, CD ROM and, in particular, the Internet among young people is unparalleled. Therefore, we make use of such tools for communication with this important target group. Following up EEZ's educational programme which achieved results we are proud of, we issued a multimedia sequence informing about nuclear power. Over twelve hundred CD-ROM discs carrying this programme were sold in two years, and in addition, several thousand visitors at exhibitions and in information centres of Czech nuclear power plants had the opportunity to watch the programme. Since the last year, EEZ has been displaying Internet pages presenting basic information about our nuclear power plants at Dukovany and Temelin; topical information is updated weekly (e.g. progress in construction of the Temelin plant, summary information concerning the construction of this plant as submitted to governmental authorities, response and answers to antinuclear activists' criticisms, ... ). The EEZ home page is linked with the home pages of the nuclear power plants themselves. Two new multimedia programmes are to be released by the end of 1998: presentation of the EEZ utility company, and Multimedia Power Encyclopaedia. Both titles will be linked to the Internet, as well as to the company intranet which is accessible to EEZ personnel. The multimedia encyclopaedia is an extension of the textual Power Encyclopaedia, which has been issued within our youth education programme. We are malting efforts for a of our multimedia products to be interlinked and to complement each other suitably. Surveys and statistical data indicate that the EEZ home page on the Internet is the most frequently visited page among the pages of Czech industrial companies. (author)

    The potential of interactive multimedia to improve biobank informed consent has yet to be investigated. The aim of this study was to test the separate effectiveness of interactivity and multimedia at improving participant understanding and confidence in understanding of informed consent compared with a standard, face-to-face (F2F) biobank consent process. A 2 (face-to-face versus multimedia) × 2 (standard versus enhanced interactivity) experimental design was used with 200 patients randomly assigned to receive informed consent. All patients received the same information provided in the biobank's nine-page consent document. Interactivity (F(1,196) = 7.56, P = 0.007, partial η(2) = 0.037) and media (F(1,196) = 4.27, P = 0.04, partial η(2) = 0.021) independently improved participants' understanding of the biobank consent. Interactivity (F(1,196) = 6.793, P = 0.01, partial η(2) = 0.033), but not media (F(1,196) = 0.455, not significant), resulted in increased participant confidence in their understanding of the biobank's consent materials. Patients took more time to complete the multimedia condition (mean = 18.2 min) than the face-to-face condition (mean = 12.6 min). This study demonstrated that interactivity and multimedia each can be effective at promoting an individual's understanding and confidence in their understanding of a biobank consent, albeit with additional time investment. Researchers should not assume that multimedia is inherently interactive, but rather should separate the two constructs when studying electronic consent.

  12. On the Accuracy Potential in Underwater/Multimedia Photogrammetry.

    Science.gov (United States)

    Maas, Hans-Gerd

    2015-07-24

    Underwater applications of photogrammetric measurement techniques usually need to deal with multimedia photogrammetry aspects, which are characterized by the necessity of handling optical rays that are refracted at interfaces between optical media with different refractive indices according to Snell's Law. This so-called multimedia geometry has to be incorporated into geometric models in order to achieve correct measurement results. The paper shows a flexible yet strict geometric model for the handling of refraction effects on the optical path, which can be implemented as a module into photogrammetric standard tools such as spatial resection, spatial intersection, bundle adjustment or epipolar line computation. The module is especially well suited for applications, where an object in water is observed by cameras in air through one or more planar glass interfaces, as it allows for some simplifications here. In the second part of the paper, several aspects, which are relevant for an assessment of the accuracy potential in underwater/multimedia photogrammetry, are discussed. These aspects include network geometry and interface planarity issues as well as effects caused by refractive index variations and dispersion and diffusion under water. All these factors contribute to a rather significant degradation of the geometric accuracy potential in underwater/multimedia photogrammetry. In practical experiments, a degradation of the quality of results by a factor two could be determined under relatively favorable conditions.

    Full Text Available Research on metacognition has consistently demonstrated that learners fail to endorse instructional designs that produce benefits to memory, and often prefer designs that actually impair comprehension. Unlike previous studies in which learners were only exposed to a single multimedia design, the current study used a within–subjects approach to examine whether exposure to both redundant text and non-redundant text multimedia presentations improved learners’ metacognitive judgments about presentation styles that promote better understanding. A redundant text multimedia presentation containing narration paired with verbatim on–screen text (Redundant was contrasted with two non-redundant text multimedia presentations: (1 narration paired with images and minimal text (Complementary or (2 narration paired with minimal text (Sparse. Learners watched presentation pairs of either Redundant + Complementary, or Redundant + Sparse. Results demonstrate that Complementary and Sparse presentations produced highest overall performance on the final comprehension assessment, but the Redundant presentation produced highest perceived understanding and engagement ratings. These findings suggest that learners misperceive the benefits of redundant text, even after direct exposure to a non-redundant, effective presentation.

    The research goal of improving patient adherence was assessed in this randomized controlled trial of the outcomes of a 15-min multimedia educational program when compared to educational literature for rheumatoid arthritis (RA) patients. One hundred eight RA patients from a Midwestern rheumatology outpatient clinic completed the self-reported Medication Adherence Questionnaire (MAQ), the Brief Illness Perception Questionnaire (BIPQ), and Health Assessment Questionnaire (HAQ) at baseline and 1 month after education. A paired samples t-test was use for data analyses to determine if there was a significant difference in the change between the groups at preintervention and 1-month postintervention. There were no significant differences in the scores between the two groups from pretest to posttest. Results from this study showed that medication adherence, illness perception, and disability were not improved by use of multimedia or the literature within 1 month. Findings from this research study showed that a short multimedia educational program is as effective as printed materials to educate patients with RA about their disease and treatment. However, neither multimedia nor literature affects medication adherence, illness perception, or disability as self-reported by patients with RA. ©2013 American Association of Nurse Practitioners.

    Multimedia models are used commonly in the initial phases of the remediation process where technical interest is focused on determining the relative importance of various exposure pathways. This report provides an approach for evaluating and critically reviewing the capabilities of multimedia models. This study focused on three specific models MEPAS Version 3.0, MMSOILS Version 2.2, and PRESTO-EPA-CPG Version 2.0. These models evaluate the transport and fate of contaminants from source to receptor through more than a single pathway. The presence of radioactive and mixed wastes at a site poses special problems. Hence, in this report, restrictions associated with the selection and application of multimedia models for sites contaminated with radioactive and mixed wastes are highlighted. This report begins with a brief introduction to the concept of multimedia modeling, followed by an overview of the three models. The remaining chapters present more technical discussions of the issues associated with each compartment and their direct application to the specific models. In these analyses, the following components are discussed: source term; air transport; ground water transport; overland flow, runoff, and surface water transport; food chain modeling; exposure assessment; dosimetry/risk assessment; uncertainty; default parameters. The report concludes with a description of evolving updates to the model; these descriptions were provided by the model developers

  6. Exploring creative activity: a software environment for multimedia systems

    Science.gov (United States)

    Farrett, Peter W.; Jardine, David A.

    1992-03-01

    This paper examines various issues related to the theory, design, and implementation of a system that supports creative activity for a multimedia environment. The system incorporates artificial intelligence notions to acquire concepts of the problem domain. This paper investigates this environment by considering a model that is a basis for a system, which supports a history of user interaction. A multimedia system that supports creative activity is problematic. It must function as a tool allowing users to experiment dynamically with their own creative reasoning process--a very nebulous task environment. It should also support the acquisition of domain knowledge so that empirical observation can be further evaluated. This paper aims to illustrate that via the reuse of domain-specific knowledge, closely related ideas can be quickly developed. This approach is useful in the following sense: Multimedia navigational systems hardcode referential links with respect to a web or network. Although users can access or control navigation in a nonlinear (static) manner, these referential links are 'frozen' and can not capture their creative actions, which are essential in tutoring or learning applications. This paper describes a multimedia assistant based on the notion of knowledge- links, which allows users to navigate through creative information in a nonlinear (dynamic) fashion. A selection of prototype code based on object-oriented techniques and logic programming partially demonstrates this.

  13. Resource optimization scheme for multimedia-enabled wireless mesh networks.

    Ali, Amjad; Ahmed, Muhammad Ejaz; Piran, Md Jalil; Suh, Doug Young

    2014-08-08

    Wireless mesh networking is a promising technology that can support numerous multimedia applications. Multimedia applications have stringent quality of service (QoS) requirements, i.e., bandwidth, delay, jitter, and packet loss ratio. Enabling such QoS-demanding applications over wireless mesh networks (WMNs) require QoS provisioning routing protocols that lead to the network resource underutilization problem. Moreover, random topology deployment leads to have some unused network resources. Therefore, resource optimization is one of the most critical design issues in multi-hop, multi-radio WMNs enabled with multimedia applications. Resource optimization has been studied extensively in the literature for wireless Ad Hoc and sensor networks, but existing studies have not considered resource underutilization issues caused by QoS provisioning routing and random topology deployment. Finding a QoS-provisioned path in wireless mesh networks is an NP complete problem. In this paper, we propose a novel Integer Linear Programming (ILP) optimization model to reconstruct the optimal connected mesh backbone topology with a minimum number of links and relay nodes which satisfies the given end-to-end QoS demands for multimedia traffic and identification of extra resources, while maintaining redundancy. We further propose a polynomial time heuristic algorithm called Link and Node Removal Considering Residual Capacity and Traffic Demands (LNR-RCTD). Simulation studies prove that our heuristic algorithm provides near-optimal results and saves about 20% of resources from being wasted by QoS provisioning routing and random topology deployment.

    Full Text Available The present day multimedia applications (MMAs are driving the computing industry as every application being developed is using multimedia in one or the other way. Computer architects are building computer systems with powerful processors to handle the MMAs. There have been tremendous changes in the design of the processors to handle different types of MMAs. We see a lot of such application specific processors today in the industry; different architectures have been proposed for processing MMAs such as VLIW, superscalar (general-purpose processor enhanced with a multimedia extension such as MMX, vector architecture, SIMD architectures, and reconfigurable computing devices. Many of the General Purpose Processors (GPPs require coprocessors to handle graphics and sound and usually those processors are either expensive or incompatible. Keeping these and the demands MMAs in mind designers have made changes to GPPs; many GPP Vendors have added instructions to their Instruction Set Architecture (ISA. All these processors use similar techniques to execute multimedia instructions. This survey paper investigates the enhancements made to the GPPS in their general Architecture as well as the ISA.

    Herrlinger, Simone; Höffler, Tim N.; Opfermann, Maria; Leutner, Detlev

    2017-06-01

    Adding pictures to a text is very common in today's education and might be especially beneficial for elementary school children, whose abilities to read and understand pure text have not yet been fully developed. Our study examined whether adding pictures supports learning of a biology text in fourth grade and whether the text modality (spoken or written) plays a role. Results indicate that overall, pictures enhanced learning but that the text should be spoken rather than written. These results are in line with instructional design principles derived from common multimedia learning theories. In addition, for elementary school children, it might be advisable to read texts out to the children. Reading by themselves and looking at pictures might overload children's cognitive capacities and especially their visual channel. In this case, text and pictures would not be integrated into one coherent mental model, and effective learning would not take place.

    The Association of American Medical Colleges' Institute for Improving Medical Education's report entitled 'Effective Use of Educational Technology' called on researchers to study the effectiveness of multimedia design principles. These principles were empirically shown to result in superior learning when used with college students in laboratory studies, but have not been studied with undergraduate medical students as participants. A pre-test/post-test control group design was used, in which the traditional-learning group received a lecture on shock using traditionally designed slides and the modified-design group received the same lecture using slides modified in accord with Mayer's principles of multimedia design. Participants included Year 3 medical students at a private, midwestern medical school progressing through their surgery clerkship during the academic year 2009-2010. The medical school divides students into four groups; each group attends the surgery clerkship during one of the four quarters of the academic year. Students in the second and third quarters served as the modified-design group (n=91) and students in the fourth-quarter clerkship served as the traditional-design group (n=39). Both student cohorts had similar levels of pre-lecture knowledge. Both groups showed significant improvements in retention (pmultimedia design compared with those instructed using the traditional design. Multimedia design principles are easy to implement and result in improved short-term retention among medical students, but empirical research is still needed to determine how these principles affect transfer of learning. Further research on applying the principles of multimedia design to medical education is needed to verify the impact it has on the long-term learning of medical students, as well as its impact on other forms of multimedia instructional programmes used in the education of medical students. © Blackwell Publishing Ltd 2011.

    Hispanic cancer patients are underrepresented in clinical trials; research suggests lack of knowledge and language barriers contribute to low accrual. Multimedia materials offer advantages to Hispanic populations because they have high acceptability, are easy to disseminate, and can be viewed with family. Hispanic cancer patients and caregivers participated in focus groups to aid in developing a Spanish-language multimedia intervention to educate Hispanic cancer patients about clinical trials. We explored the feasibility of delivering the intervention in medical oncology clinics. A total of 35 patients were randomized to either the multimedia intervention group (n = 18) or a control group (n = 17) who were asked to read the National Cancer Institute's Spanish-language clinical trials brochure. Self-reported data on knowledge about and attitudes toward clinical trials, self-efficacy for participating in a clinical trial, intention to participate in a clinical trial if asked, and receptivity to information about a clinical trial were collected at baseline and 10 days later. Delivery of the multimedia presentation in oncology clinics was feasible. The intervention group had more knowledge about clinical trials at follow-up than the control group; scores for intention to participate in a clinical trial by participants in the intervention group increased from 3.8 to 4.0 of a possible 5, but declined in the control group from 4.5 to 4.1. No statistically significant difference was detected between groups in scores for attitudes or self-efficacy for making a decision to participate in a clinical trial. Our sample size was inadequate to identify differences between the informational methods. Although all patients were asked about their willingness to participate in a clinical trial, this decision was hypothetical. In addition, the study was conducted with a sample of Spanish-speaking Hispanic cancer patients at a comprehensive cancer center in Florida. Thus, the results

    Any new fuel in California requires approval by the state agencies overseeing human and environmental health. In order to provide a systematic evaluation of new fuel impacts, California now requires a multimedia risk assessment (MMRA) for fuel approval. The fuel MMRA involves all relevant state agencies including: the California Air Resources Board (CARB), the State Water Resources Control Board (SWRCB), the Office of Environmental Health Hazards Assessment (OEHHA), and the Department of Toxic Substances Control (DTSC) overseen by the California Environmental Protection Agency (CalEPA). The lead agency for MMRAs is the CARB. The original law requiring a multimedia assessment is California Health and Safety Code 43830.8. In addition, the low carbon fuel standard (LCFS), the Global Warming Solutions Act (AB32), and the Verified Diesel Emission Control Strategy (VDECS) have provisions that can require a multimedia assessment. In this presentation, I give an overview of the California multimedia risk assessment (MMRA) for new fuels that has been recently developed and applied to several alternative fuels. The objective of the California MMRA is to assess risk of potential impacts of new fuels to multiple environmental media including: air, water, and soil. Attainment of this objective involves many challenges, including varying levels of uncertainty, relative comparison of incommensurate risk factors, and differing levels of priority assigned to risk factors. The MMRA is based on a strategy of relative risk assessment and flexible accommodation of distinct and diverse fuel formulations. The approach is tiered by design, in order to allow for sequentially more sophisticated investigations as knowledge gaps are identified and re-prioritized by the ongoing research. The assessment also involves peer review in order to provide coupling between risk assessment and stakeholder investment, as well as constructive or confrontational feedback. The multimedia assessment

    2015-01-01

    Full Text Available We have proposed preprocessing techniques for high-efficiency data compression in wireless multimedia sensor networks. To do this, we analyzed the characteristics of multimedia data under the environment of wireless multimedia sensor networks. The proposed preprocessing techniques consider the characteristics of sensed multimedia data to perform the first stage preprocessing by deleting the low priority bits that do not affect the image quality. The second stage preprocessing is also performed for the undeleted high priority bits. By performing these two-stage preprocessing techniques, it is possible to reduce the multimedia data size in large. To show the superiority of our techniques, we simulated the existing multimedia data compression scheme with/without our preprocessing techniques. Our experimental results show that our proposed techniques increase compression ratio while reducing compression operations compared to the existing compression scheme without preprocessing techniques.

    1999-01-01

    Multimedia applications and specifically voice and video conferencing tools are widely used in business communications, and are quickly being discovered by the consumer market as well. At the same time, wireless communication services such as PCS voice and cellular data are becoming very popular, leading to the desire to deploy multimedia applications in the wireless environment. Wireless links, however, exhibit several characteristics which are different from traditional wired networks. These include: dynamically changing bandwidth due to mobile host movement in and out of cell where bandwidth is shared, high rates of packet corruption and subsequent loss, and frequent are lengthy disconnections due to obstacles, fading, and movement between cells. In addition, these effects are short-lived and difficult to reproduce, leading to a lack of adequate testing and analysis for applications used in wireless environments.

    Pisciella, Paolo; Zoric, Josip; Gaivoronski, Alexei A.

    In this paper we analyze quantitatively a business model for the collaborative provision of an advanced mobile data service portfolio composed of three multimedia services: Video on Demand, Internet Protocol Television and User Generated Content. We provide a description of the provision system considering the relation occurring between tecnical aspects and business aspects for each agent providing the basic multimedia service. Such a techno-business analysis is then projected into a mathematical model dealing with the problem of the definition of incentives between the different agents involved in a collaborative service provision. Through the implementation of this model we aim at shaping the behaviour of each of the contributing agents modifying the level of profitability that the Service Portfolio yields to each of them.

    With the technology development of network information, there exists more and more seriously questions to our education. Computer multimedia application breaks the traditional foreign language teaching and brings new challenges and opportunities for the education. Through the multiple media application, the teaching process is full of animation, image, voice, and characters. This can improve the learning initiative and objective with great development of learning efficiency. During the traditional foreign language teaching, people use characters learning. However, through this method, the theory performance is good but the practical application is low. During the long time computer multimedia application in the foreign language teaching, many teachers still have prejudice. Therefore, the method is not obtaining the effect. After all the above, the research has significant meaning for improving the teaching quality of foreign language.

    On the commercial available server, the great workloads on CPU generally limit the performance of Input/Output (I/O) or delay the response time. A Network-Attached Storage Device (NASD) is developed to meet the scalability requirement of mass multimedia storage. The evaluating experiments in this paper indicate that the bottleneck of data transmission is not the capability of CPU, but the network and reading/recording speed of physical storage devices. To improve the performance of multimedia storage system, a scheme of NASD-based multi-port storage area network is presented. In the new system composed of one manager and several NASDs, the manager only assigns the task of data processing to the NASDs. The NASDs can dynamically generate the virtual files and sent them to clients directly. Act as a virtual server, the storage system can provide the multi-port service for the different clients and different requirements.

    The paper presents the use of the concepts and modelling principles of the Open Systems Interconnection (OSI) upper layers structure in the modelling of multimedia teleservices. It puts emphasis on the revised Application Layer Structure (OSI/ALS). OSI/ALS is an object based reference model which intends to coordinate the development of application oriented services and protocols in a consistent and modular way. It enables the rapid deployment and integrated use of these services. The paper emphasizes further on the nesting structure defined in OSI/ALS which allows the design of scalable and user tailorable/controllable teleservices. OSI/ALS consistent teleservices are moreover implementable on communication platforms of different capabilities. An analysis of distributed multimedia architectures which can be found in the literature, confirms the ability of the OSI/ALS framework to model the interworking functionalities of teleservices.

    Jimison, Holly B.; Sher, Paul P.; Appleyard, Richard; LeVernois, Yvonne

    1998-01-01

    Abstract Objective: The goal of the project was to create recommendations and design specifications for a multimedia tool to enhance the informed consent process for clinical trials. The authors focused on the needs of patients with potential cognitive impairment. Design: The authors first performed a needs assessment using focus groups and interviews with health care researchers, institutional review board members, and three groups of patients (who had depression, breast cancer, or schizophrenia). Their feedback was incorporated into the design of a prototype multimedia tool. The design included general modules with information about clinical trials and informed consent as well as trial-specific modules. The authors then used the resulting prototype multimedia tool for informed consent in follow-up focus groups and interviews to obtain feedback on the feasibility and potential effectiveness of using such a tool routinely for clinical trials. Results: The authors showed that it was feasible to adapt a structured multimedia informed consent system to a specific clinical trial and to incorporate techniques to improve the understandability of informed consent content. Patients generally felt the prototype system was useful and could replace the paper document. They felt using the system would be less stressful, because they would have a greater sense of control and could proceed at their own pace. They liked the hierarchic and modular approach to providing information and felt that the use of video made information more understandable. Researchers and institutional review board members also found the system to be valuable in these ways but had concerns about how to review the system for potential biases in presentation and about the legal issues associated with replacing the paper document.

    Science.gov (United States)

    Jensch, Peter F.; Niemann, Heino

    1990-08-01

    ISDN provides the end user with a large number of services and the flexibility to easily modify the services they receive as their communications needs grow and change. It is our goal to use the advantages of the ISDNtechnology for a medical end user by supporting him with integrated image/voice/data information. We focus our developments to medical scenarios where general PACS concepts are not acceptable, currently or in the near future. An image/voice/data management and communications system using ISDN technology has been designed. First applications are developed - to acquire multiple image modalities such as CT, Angio and NI from several hospital departments, - to communicate with a remote image processing group (Computer Science Department), - to complement visual results wIth voice and data yielding integrated multimedia information, and - to distribute integrated multimedia information to medical end users such as surgeons and therapists. The integrated multimedia information is finally available at a specially configured PC-workstation in complete digital form. An interactive replay of this information complies with a video-standard (either NTSC or PAL) and may discard specific media-modality on demand. At any time a video copy of the complete or constituent integrated information can be saved on VHS-cassettes for further distribution. The image processing group currently creates standardized video clips for frequent surgical scenarios. This paper describes the network model for the in-house and remote ISDN communication of integrated multimedia information, traffic, and performance requirements. The flexibility and acceptance of this approach will be addressed by reviewing several surgical cases.

    Cloud computing has innovated the IT industry in recent years, as it can delivery subscription-based services to users in the pay-as-you-go model. Meanwhile, multimedia cloud computing is emerging based on cloud computing to provide a variety of media services on the Internet. However, with the growing popularity of multimedia cloud computing, its large energy consumption cannot only contribute to greenhouse gas emissions, but also result in the rising of cloud users' costs. Therefore, the multimedia cloud providers should try to minimize its energy consumption as much as possible while satisfying the consumers' resource requirements and guaranteeing quality of service (QoS). In this paper, we have proposed a remaining utilization-aware (RUA) algorithm for virtual machine (VM) placement, and a power-aware algorithm (PA) is proposed to find proper hosts to shut down for energy saving. These two algorithms have been combined and applied to cloud data centers for completing the process of VM consolidation. Simulation results have shown that there exists a trade-off between the cloud data center's energy consumption and service-level agreement (SLA) violations. Besides, the RUA algorithm is able to deal with variable workload to prevent hosts from overloading after VM placement and to reduce the SLA violations dramatically.

    Education in reproductive science is operating from an outdated paradigm of teaching and learning. Traditionally, reproductive education follows the pattern where students read a textbook, listen to instructor presentations, re-read the textbook and class notes and then complete a test. This paradigm is inefficient, costly and has not incorporated the potential that technology can offer with respect to increases in student learning. Further, teachers of reproductive science (and all of science for that matter) have little training in the use of documented methods of instructional design and cognitive psychology. Thus, most of us have learned to teach by repeating the approaches our mentors used (both good and bad). The technology now exists to explain complex topics using multimedia presentations in which digital animation and three-dimensional anatomical reconstructions greatly reduce time required for delivery while at the same time improving student understanding. With funding from the Small Business Innovation Research program through the U.S. Department of Education, we have developed and tested a multimedia approach to teaching complex concepts in reproductive physiology. The results of five separate experiments involving 1058 university students and 122 patients in an OB/GYN clinic indicate that students and patients learned as much or more in less time when viewing the multimedia presentations when compared to traditional teaching methodologies. © 2012 Blackwell Verlag GmbH.

    The purpose of this experimental study is to investigate the effects of using content acquisition podcasts (CAPs), an example of instructional technology, to provide vocabulary instruction to adolescents with and without learning disabilities (LD). A total of 279 urban high school students, including 30 with LD in an area related to reading, were randomly assigned to one of four experimental conditions with instruction occurring at individual computer terminals over a 3-week period. Each of the four conditions contained different configurations of multimedia-based instruction and evidence-based vocabulary instruction. Dependent measures of vocabulary knowledge indicated that students with LD who received vocabulary instruction using CAPs through an explicit instructional methodology and the keyword mnemonic strategy significantly outperformed other students with LD who were taught using the same content, but with multimedia instruction that did not adhere to a specific theoretical design framework. Results for general education students mirrored those for students with LD. Students also completed a satisfaction measure following instruction with multimedia and expressed overall agreement that CAPs are useful for learning vocabulary terms. © Hammill Institute on Disabilities 2013.

    Full Text Available Today’s eLearning websites are heavily loaded with multimedia contents, which are often unstructured, unedited, unsynchronized, and lack inter-links among different multimedia components. Hyperlinking different media modality may provide a solution for quick navigation and easy retrieval of pedagogical content in media driven eLearning websites. In addition, finding meta-data information to describe and annotate media content in eLearning platforms is challenging, laborious, prone to errors, and time-consuming task. Thus annotations for multimedia especially of lecture videos became an important part of video learning objects. To address this issue, this paper proposes three major contributions namely, automated video annotation, the 3-Dimensional (3D tag clouds, and the hyper interactive presenter (HIP eLearning platform. Combining existing state-of-the-art SIFT together with tag cloud, a novel approach for automatic lecture video annotation for the HIP is proposed. New video annotations are implemented automatically providing the needed random access in lecture videos within the platform, and a 3D tag cloud is proposed as a new way of user interaction mechanism. A preliminary study of the usefulness of the system has been carried out, and the initial results suggest that 70% of the students opted for using HIP as their preferred eLearning platform at Gjøvik University College (GUC.

    2017-05-01

    Multimedia event detection has been one of the major endeavors in video event analysis. A variety of approaches have been proposed recently to tackle this problem. Among others, using semantic representation has been accredited for its promising performance and desirable ability for human-understandable reasoning. To generate semantic representation, we usually utilize several external image/video archives and apply the concept detectors trained on them to the event videos. Due to the intrinsic difference of these archives, the resulted representation is presumable to have different predicting capabilities for a certain event. Notwithstanding, not much work is available for assessing the efficacy of semantic representation from the source-level. On the other hand, it is plausible to perceive that some concepts are noisy for detecting a specific event. Motivated by these two shortcomings, we propose a bi-level semantic representation analyzing method. Regarding source-level, our method learns weights of semantic representation attained from different multimedia archives. Meanwhile, it restrains the negative influence of noisy or irrelevant concepts in the overall concept-level. In addition, we particularly focus on efficient multimedia event detection with few positive examples, which is highly appreciated in the real-world scenario. We perform extensive experiments on the challenging TRECVID MED 2013 and 2014 datasets with encouraging results that validate the efficacy of our proposed approach.

    One of the challenges for characterizing and modeling realistic multimedia applications is the lack of access to source codes. On-chip performance counters effectively resolve this problem by monitoring run-time behaviors at the instruction-level. This paper presents a novel technique of characterizing and modeling workloads at the instruction level for realistic multimedia applications using hardware performance counters. A variety of instruction counts are collected from some multimedia applications, such as RealPlayer, GSM Vocoder, MPEG encoder/decoder, and speech synthesizer. These instruction counts can be used to form a set of abstract characteristic parameters directly related to a processor`s architectural features. Based on microprocessor architectural constraints and these calculated abstract parameters, the architectural performance bottleneck for a specific application can be estimated. Meanwhile, the bottleneck estimation can provide suggestions about viable architectural/functional improvement for certain workloads. The biggest advantage of this new characterization technique is a better understanding of processor utilization efficiency and architectural bottleneck for each application. This technique also provides predictive insight of future architectural enhancements and their affect on current codes. In this paper the authors also attempt to model architectural effect on processor utilization without memory influence. They derive formulas for calculating CPI{sub 0}, CPI without memory effect, and they quantify utilization of architectural parameters. These equations are architecturally diagnostic and predictive in nature. Results provide promise in code characterization, and empirical/analytical modeling.

    2012-05-01

    To systematically assess the physicians' point of view of multimedia support in preoperative patient education for radical prostatectomy. We evaluated the view of physicians performing multimedia supported preoperative educations within a randomized controlled trial. Therein 8 physicians educated 203 patients for radical prostatectomy. All physicians rated multimedia supported education better than the standard procedure. Main reasons were better comprehensibility, the visual presentation, and greater ease in explaining complex issues. Objective time measurement showed no difference between both educations. The major disadvantage was the impression, that multimedia supported education lasted longer. Moreover, they had the impression that some details could be further improved. Given the choice, every physician would decide for multimedia support. Physicians appreciate multimedia support in preoperative education and contrary to their impression, multimedia support does not prolong patient education. Therefore, patients and physicians likewise profit from multimedia support for education and counseling. The readiness of physicians is a possible obstacle to this improvement, as their view is a key factor for the transition to everyday routine. Therefore, our results could alleviate this possible barrier for establishing multimedia supported education in clinical routine. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The design of a novel non-contact multimedia controller is proposed in this study. Nowadays, multimedia controllers are generally used by patients and nursing assistants in the hospital. Conventional multimedia controllers usually involve in manual operation or other physical movements. However, it is more difficult for the disabled patients to operate the conventional multimedia controller by themselves; they might totally depend on others. Different from other multimedia controllers, the proposed system provides a novel concept of controlling multimedia via visual stimuli, without manual operation. The disabled patients can easily operate the proposed multimedia system by focusing on the control icons of a visual stimulus device, where a commercial tablet is used as the visual stimulus device. Moreover, a wearable and wireless electroencephalogram (EEG) acquisition device is also designed and implemented to easily monitor the user's EEG signals in daily life. Finally, the proposed system has been validated. The experimental result shows that the proposed system can effectively measure and extract the EEG feature related to visual stimuli, and its information transfer rate is also good. Therefore, the proposed non-contact multimedia controller exactly provides a good prototype of novel multimedia controlling scheme. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2014-10-01

    Full Text Available This paper is an academic observation of an Educational Multimedia Content development-training programme funded by the Commonwealth of Learning (COL in Tanzania. This project focused on skills development in script writing and in radio and video programme development, aimed at transforming selected subjects from text to multimedia content. The ultimate objective was to enable better and easy understanding of the lessons, for Open and Distance Learning learners. A group of 25 teachers from the Tanzania’s Institute of Adult Education participated in the training and development of the programmes. In this paper the author shares the new and exciting experiences of teachers on adding such skills to their professional career, as the development of these programmes. Author’s own participation and interviews with peers in the project were employed as methods of data collection. A total number of 13 videos and 12 radio programmes were developed over the span of six months. Five school subjects were covered, namely: English, Mathematics, Biology, History and Geography. Some of the challenges encountered in developing the programmes included: difficulties in developing a video idea from the textbooks; working as a group online in collaboration with the training consultant in another country especially in script development; memorizing words (as actors playing in the productions and saying it on camera; and time constraints (working under pressure. The author recommends to African nations and educators in other parts of the world to access these multimedia-learning programmes online since they are OER, and to use them in their context. The video and radio programmes reflect the Tanzanian context to some extent, but most of the lessons are general for use by any country. The paper concludes that skills development on technological innovations among ODL teachers in both formal and non-formal education system is essential towards attaining EFA goals.

    Full Text Available The fragmentation of the school’s knowledge is configured in a harmful way to the teaching, making it harder to the student, the appropriation of knowledge and the construction of a contextualized vision that would allow them a critical perception of reality. In the trials of overcoming the fragmentation, we observe as possibilities, the usage of strategies faced with the traditional program, the inclusion of History and Biology’s Philosophy (HFB and the insertion of practical and joinable classes. Therefore, some reflexions are presented that emerged from the strategies development to the proposal of practical classes during the internship program, with freshmen groups from the High School in a public school. Strategies were developed to the cellular biology contents and its human aspects. Our challenge was made of the planning starting from the Teaching Strategies, in a perspective of reaching the Biology from the “Constitution of the Biologic Knowledge and from practical activities that emphasize the usage of experiments and construction of models. Although many difficulties may have appeared during the process, the motivation and the envelopment shown by the students confirm the didactic potential of the strategies in the classroom and the modality of the teaching in practical classes
