  9. GLOBALIZATION, COMMUNICATION, EDUCATION

    Directory of Open Access Journals (Sweden)

    Monica Condruz-Bacescu

    2018-03-01

    Full Text Available The paper focuses on the issues of globalization, communication and education. Globalization has become the fundamental theme of political discourse, through its economic dimension, namely by opening up the economic markets in search of new stability points of contemporary developed capitalism; a phenomenon that has led to the free movement of labor, thus involving the social dimension, the circle being closed with the educational dimension because the individual, regardless of the cultural context in which he/she lives, needs training. The global economy cannot be conceived without international communication, which has become a premise of economic success in recent decades. Such communication on which the economic partnerships and multinational organizations are based presupposes an accurate perception and interpretation of the different cultures other than those in which the economic activity takes place and a permanent negotiation of the symbols and reference systems. Education undoubtedly plays an important role in any attempt to address communication networks in these moments of explosive development, networks that mediate communication between people and can thereby help to bring them closer together. Education must directly follow the transformations and new requirements in order to support future changes and professional training. In this direction, education will have as an educational purpose the development of the consciousness of the links between the different components and participants, regardless of the geographic area in which they operate, and on this basis the building of the partnership. Education needs to efficiently and extensively convey that knowledge and information adapted to the new civilization of globalization that does not overwhelm but contribute to the development of people at individual and community level. It must also trace the transformations of the new world that is constantly moving, and at the same time

    1997-12-01

    Full Text Available In their paper the authors point to the importance of communication in adult education, seeing man as a relational creature. They stress the importance verbal as well as non-verbal communication, which discloses the speaker's attitude to both what is being said and the students. The authors detail the components of non-verbal communication, which the group leaders can use as guide­ lines in their educational work. They define constructive and destructive, content-related and relationship-related types of communication, concluding that communication is at its best when it is relaxed and involves all members of the group as well as the tutor-organiser. Only then can feedback be generated, resulting in a closer connectedness and enhanced quality of the process of education.

The results reveal that this type of communication has gained more ground in academia creating real social communities, and students use it more and more for collaboration in various activities involved in the higher education system, but also for socializing and information.

  17. Teaching good communication/proposal-writing skills: Overcoming one deficit of our educational system

    Science.gov (United States)

    Reif-Lehrer, Liane

    1992-09-01

    Good communication skills require: (1) an understanding of one's audience and the subtle interactions between writer and reader, (2) organizational skills to methodically progress through the necessary stages of a project (e.g., writing a proposal), and (3) certain basic communication (writing/speaking) skills, i.e., a facility with the basic elements of transmitting information clearly. The task of writing a grant proposal in response to a specific set of instructions is used to illustrate the analysis and responses necessary to complete a major written communication project. The concept of focusing on—and writing for—the reader (in this case, the proposal reviewer) is emphasized. Although good communication skills affect life-styles, productivity, and economics in our society, the communication skills of the American pubic are sorely lacking—even among people with high levels of education—because students receive little training in these skills in the United States educational system. However, such skills can be taught to younger students as well as to adults.

    Joels, K. M.

    1978-01-01

    The components of an educational system based on, and perhaps enhanced by, space industrialization communications technology are considered. Satellite technology has introduced a synoptic distribution system for various transmittable educational media. The cost of communications satellite distribution for educational programming has been high. It has, therefore, been proposed to utilize Space Shuttle related technology and Large Space Structures (LSS) to construct a system with a quantum advancement in communication capability and a quantum reduction in user cost. LSS for communications purposes have three basic advantages for both developed and emerging nations, including the ability to distribute signals over wide geographic areas, the reduced cost of satellite communications systems versus installation of land based systems, and the ability of a communication satellite system to create instant educational networks.

  7. Education, Training and Communication: Introduction

    International Nuclear Information System (INIS)

    Coeck, M.

    2007-01-01

    Good communication on nuclear science and its applications is a challenging practice. Nuclear topics are generally perceived as being complex from the technical-scientific point of view, and also from the societal point of view, agreement and acceptance is not straightforward. Moreover, the application fields of ionising radiation are numerous and spread over many areas. The nuclear industry and the nuclear research sector, the medical sector, several branches of the non-nuclear industry and several disciplines in the academic world, all appeal on the phenomenon of the nuclear process of reduction of an excess of inner energy, called radioactivity. Besides these sectors who consciously use radioactivity in one or other application, other branches such as aviation and the fossil fuel industry are faced with artificially raised levels of natural radioactivity. Maintaining a high level in nuclear competencies is crucial in order to guarantee the safe use of current nuclear applications and to ensure the protection of workers, the public and the environment. Next to this, an up-to-date nuclear knowledge is vital in research and development related to the optimisation of current and the development of future technologies. An essential component in ensuring a high level of expertise in the future is a sustainable Education and Training infrastructure. Educational systems provide the initial study to young learners. It is knowledge-based and generally provided by the academic world. Complementary to education is the unceasing maintenance of the level of competencies. Training activities need to be provided to young and not-so-young professionals working with ionizing radiation in all disciplines and at all levels. When it comes to the future development and the realization of new great infrastructures, obviously preservation of knowledge through education and training is a necessary but not sufficient element, and also research itself is subject to support by government

    Although the implementation of picture archiving and communication system (PACS) could increase productivity of radiology departments, this depends on factors such as the PACS competence of radiologic technologists (RTs). The purpose of this study was to investigate the RTs' perceptions of PACS competence and educational issues in Western Australia (WA). A hardcopy questionnaire was distributed to WA RTs for obtaining their perceptions of PACS competence and educational issues. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (t test and analysis of variance) were used to analyze the responses of the multiple choice and five-point scale questions from the returned questionnaires. The questionnaire response rate was 57.7% (173 out of 300). The mean values of all PACS competence questions except questions 2e-g are in the range of 3.9-4.9, i.e., around competent to very competent. Participants indicated they received adequate PACS training (mean 3.8). Statistically significant variables influencing RTs' perceptions of their PACS competence and educational issues including the age (p education received (p system, and received adequate training. However, future PACS education programs should be tailored to different RTs' groups. For example, multiple training modules might be necessary to support the PACS competence development of older RTs and those with lower general computer literacy.

    People are apprehensive that a strong earthquake with a magnitude of nearly 8 may occur in Tokai area. The whole area of Shizuoka Prefecture has been specified as the specially strengthened region for earthquake disaster measures. This report outlines the communication system for emergency with respect to atomic disaster caused by an earthquake. Previously, wireless receiving system is stationed in the whole area to simultaneously inform the related news to the residents and so, communications with them are possible at any time by using the system. Since mobile wireless receiving sets are stationed in all town halls, self defense organizations and all the places of refuge, mutual communications are possible. These communication system can be utilized for either earthquake or nuclear disaster. Further, Shizuoka general information network system has been established as a communication system for anti-disaster organization and a wireless network via a communication satellite, ''super bird'' has been constructed in addition to the ground network. Therefore, the two communication routes became usable at emergency and the systems are available in either of nuclear disaster or earthquake. (M.N.)

    The Urban population of developing countries is predicted to rise from one third in 1990 to over 50% by 2025. In 1950 the world's total urban population was 734 million, of whom 448 million were living in developed countries and remaining 286 were in developing region. The total population on earth is predicted to increase by more than one billion people within the next 15 years, reaching 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100. Looking at the ever increasing urbanization.In 2016, an estimated 54.5 per cent of the world's populations inhabited in urban region. By 2030, urban areas are projected to shelter 60 per cent of people worldwide and one in every three people will live in cities with at least half a million inhabitants.On the basis of these figures and other global trends, it would appear that Africa and Asia will have the highest share of world's urban growth in next 25 years, resulting consideration rise of large number of metropolitan cities and towns. Therefore issues related to urban climate change will be important for socio economic development for urban transformation through environmental sustainability.The information and communication systems plays an important role in achieving the social sustainability through environmental sustainability for urban transformation.

The system is composed of a command center and facility sub-systems. A command center is a mini-computer system to process C/S (Containment and Surveillance) status data. Facility sub-systems consists of OSM (On-site Multiplexer), MU (Monitoring Unit) and C/S sensor. The system uses public telephone network for communication between a command center and facility sub-systems, and it encrypts communication data to prevent falsification and wiretapping by unauthorized persons. This system inherits the design principle of RECOVER system that was tested by IAEA before. We upgraded and expanded its capabilities more than those of RECOVER. The development of this system began in 1983, and it finished in 1987. Performance tests of the system were carried out since 1987. It showed a farely good result with some indications which should need further improvements. The Upgraded RECOVER system provides timely information about the status of C/S systems, which could contribute to the reduction of inspection effort and the improvement of cost performance.

    Rapid and ongoing development in the energy sector has consequences for system control at all levels. In relation to system control and communication the control system is challenged in five important ways: 1) Expectations for security of supply, robustness and vulnerability are becoming more stringent, and the control system plays a big part in meeting these expectations. 2) Services are becoming increasingly based on markets that involve the transmission system operators (TSOs), generators and distribution companies. Timely, accurate and secure communication is essential to the smooth running of the markets. 3) Adding large amounts of renewable energy (RE) to the mix is a challenge for control systems because of the intermittent availability of many RE sources. 4) Increasing the number of active components in the system, such as small CHP plants, micro-CHP and intelligent loads, means that the system control will be much more complex. 5) In the future it is likely that power, heat, gas, transport and communication systems will be tighter coupled and interact much more.

    2017-12-01

    Studies that suggest an increased number of bachelor's prepared nurses (BSNs) at the bedside improves patient safety do not stratify their samples into traditional bachelor's and associates (ADN) to BSN graduates. This qualitative study investigated potential differences in patient safety meaning among BSNs and ADN to BSN graduates. Guided by the theory of Language Convergence/Meaning Divergence, interview data from eight BSN and eight ADN to BSN graduates were analyzed. Findings indicate there are two meaning levels or systems, the local level and the systemic level. At the local level, the meaning of patient safety is focused at the patient's bedside and regulated by the nurse. The systemic level included the notion that health system factors such as policies and staffing are paramount to keeping patients safe. More frequently, ADN to BSN graduates' meaning of patient safety was at the local level, while BSNs' meaning centered at the systemic level.

    Full Text Available The growing demand of bandwidth in this modern internet age has been testing the existing telecommunication infrastructures around the world. With broadband speeds moving towards the region of Gbps and Tbps, many researches have begun on the development of using optical wireless technology as feasible and future methods to the current wireless technology. Unlike the existing radio frequency wireless applications, optical wireless uses electromagnetic spectrums that are unlicensed and free. With that, this project aim to understand and gain better understanding of optical wireless communication system by building an experimental and simulated model. The quality of service and system performance will be investigated and reviewed. This project employs laser diode as the propagation medium and successfully transferred audio signals as far as 15 meters. On its quality of service, results of the project model reveal that the bit error rate increases, signal-to-noise ratio and quality factor decreases as the link distance between the transmitter and receiver increases. OptiSystem was used to build the simulated model and MATLAB was used to assist signal-to-noise ratio calculations. By comparing the simulated and experimental receiver’s power output, the experimental model’s efficiency is at 66.3%. Other than the system’s performance, challenges and factors affecting the system have been investigated and discussed. Such challenges include beam divergence, misalignment and particle absorption.

    Full Text Available This essay assesses the communications and information systems (CIS in support of the civilian and military structures deployed in the European Union led crises management operations and missions. The article emphasizes the specific structure and function of CIS taking in consideration the particularities of EU led missions. The integration of the EU institutional networks and systems with the national systems provided by the EU member states is considered a key element. The analysis-part of this paper starts with the specific EU command and control system for crises management missions based on two autonomous solutions and one relying on NATO capabilities. Further, it continues with the challenges of the classifi ed information exchange at the operational theatre level. The most important contribution of this article is based on the long term vision implementation measures for the CIS structure, roles, functions and services provided and the information management infrastructure. CIS deployment mechanisms are described with references to the practical situation of the CIS deployed in support of crises management operations and missions. Two important defi nitions are provided regarding the CIS for crisis management and their roles in the specific EU operational environment. The system view of the operational CIS is depicted and analysed also, with a focus on the integration aspects of the infrastructure as the information transport layer for the information exchange flow. The last part of the article focuses on the CIS functions for the deployed systems which are detailed alongside with the C2 and Information Exchange Requirements in the EU operational environment. The variety of the theoretical approaches to determine the CIS infrastructure for EU-led civilian and military missions triggers the conclusion that the planning and implementation process is extremely complex especially in the context of the new security environment and requires

    Hart, Nick; Haugli, Hans-C.; Poskett, Peter; Smith, K.

    Inmarsat has been providing near global mobile satellite communications since 1982 and Inmarsat terminals are currently being used in more than 130 countries. The terminals have been reduced in size and cost over the years and new technology has enabled the recent introduction of briefcase sized personal telephony terminals (Inmarsat-M). This trend continues and we are likely to see Inmarsat handheld terminals by the end of the decade. These terminals are called Inmarsat-P and this paper focuses on the various elements required to support a high quality service to handheld terminals. The main system elements are: the handheld terminals; the space segment with the associated orbits; and the gateways to terrestrial networks. It is both likely and desirable that personal handheld satellite communications will be offered by more than one system provider and this competition will ensure strong emphasis on service quality and cost of ownership. The handheld terminals also have to be attractive to a large number of potential users, and this means that the terminals must be small enough to fit in a pocket. Battery lifetime is another important consideration, and this coupled with radiation safety requirements limits the maximum radiated EIRP. The terminal G/T is mainly constrained by the gain of the omnidirectional antenna and the noise figure of the RF front end (including input losses). Inmarsat has examined, with the support of industry, a number of Geosynchronous (GSO), Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) satellite options for the provision of a handheld mobile satellite service. This paper describes the key satellite and orbit parameters and tradeoffs which affect the overall quality of service and the space segment costing. The paper also stresses not only the importance of using and sharing the available mobile frequency band allocations efficiently, but also the key considerations affecting the choice of feeder link bands. The design of the gateways

    Administrators must make well-informed decisions regarding new communications technology to disseminate information to diverse constituencies in the facility and its service area. For example, communicating and using information about rapidly changing regulations is important in today's competitive environment. Administrators are faced with choosing from among such electronic media as satellite programming, telephone systems, cable television, and microwave radio to meet their institutions' needs. Teleconferences and closed-circuit educational programming also offer cost-efficient choices. Consultants can assist the management team in developing an appropriate system, whether sharing in an existing program or private network or installing an independent satellite-receiving dish, or "downlink." The team, including medical personnel, must choose the hardware that the institution can use most effectively in accomplishing its objectives. Studying other facilities' systems, such as St. Joseph Hospital, Providence, RI, with its independent receiving dish, shows the practical applications of the often confusing technology. Administrators should not be put off by "'technology frenzy." About 600 U.S. institutions have receiving stations or access to them; most will have them in the future. Even smaller facilities can become leaders with this cost-effective technology. Administrations must lead in accepting the challenge to improve health care communications.

    Underwater communication has a range of applications including remotely operated vehicle (ROV) and autonomous underwater vehicle (AUV) communication and docking in the offshore industry. Current underwater transmission techniques is primarily utilise sound waves for large distance at lower frequencies and the velocity of sound in water is approximately 1500m/s the resultant communications have problems with multi-path propagation and low bandwidth problems. The use of electromagnetic (EM) techniques underwater has largely been overlooked because of the attenuation due to the conductivity of seawater. However, for short range applications, the higher frequencies and much higher velocity can prove advantageous. This paper will outline a project which will utilise recent investigations that demonstrate EM wave propagation up to the MHz frequency range is possible in seawater.

    Schottenfeld, Faith

    The purpose of this study was to explore the dynamics of the environmental risk communication process. The goal was to look at the totality of the process by examining the different components: entry to communication (what brings people into the process), maintenance of communication (behaviors of participants, pathways to successful risk communication, barriers to successful risk communication, characteristics of the dialogue) and outcomes of risk communication (what has been learned, what moves the process to social action, what else can come of the process). Interviews and critical incidents were used to explore the experiences of risk communicators in four different practice settings: academia, industry/trade groups, community-based organizations and government. Twenty-four people completed critical incident stories and sixteen participated in in-depth interviews. Data were coded and analyzed for themes. Findings illustrated that successful risk communication results from a deliberative, or purposeful process. This process includes a systematic approach to identifying and inviting people to participate, while considering specific motivating factors that affect participation. Risk communication is maintained by creating and nurturing structured forums for dialogue by acknowledging the varying perspectives of the people who participate and the contextual settings of environmental risks. The result of effective dialogue may range from increased knowledge, to transformative learning to social action and policy change. The researcher recommended that a multi-disciplinary team including risk communicators, adult educators and scientists can work most effectively to plan, implement and evaluate a risk communication process.

    Full Text Available The communication system is highly developed in the academic environment and not only involves the communication between the university and the outside world through exchanges of messages, but also the internal one with the employees and students. Online communication has gained increasingly more territory in the academic environment lately, especially thanks to the usage of e-mails and social networks. Therefore, this paper aims at presenting the main tools of the online communication in higher education as well as their importance of creating interaction among the participants in the education process. The conclusions emphasize that this type of communication significantly favors the teaching-learning process, creates real interaction between students and professors and contributes to the fast dissemination and access of information.

    2011-01-01

    Full Text Available The paper considers alternative constructivism as a possibility of theoretical starting point regarding education as a factor of intercultural communication. The introductory part of the paper deals with Kelly’s personal construct theory permeating the arguments in favour of the theoretical research thesis referring to the issue of the extent the pluralism of European culture space interferes with national culture through education. Furthermore, the paper considers the way pedagogy has been searching for more comprehensive self-observation, self-reflection and self-determination on its way to self-change in order to ensure freedom of personal action according to contemporary philosophical discussions. The importance of education as a factor of intercultural communication has been supported by the outcomes of an explorative empirical research, which is an element bonding all the reflections in the text. Finally, the key competences for intercultural communication have been stated in the paper.

  10. An alarm multiplexer communication system

    International Nuclear Information System (INIS)

    Herrera, G.V.

    1986-01-01

    A low cost Alarm Multiplexer Communication System (AMCS) has been developed to perform the security sensor monitoring and control functions and to provide remote relay control capability for integrated security systems. AMCS has a distributed multiplexer/repeater architecture with up to four dual communication loops and dual control computers that guarantee total system operation under any single point failure condition. Each AMCS can control up to 4096 sensors and 2048 remote relays. AMCS reports alarm status information to and is controlled by either one or two Host computers. This allows for independent operation of primary and backup security command centers. AMCS communicates with the Host computers over an asynchronous serial communication link and has a message protocol which allows AMCS to fully recover from lost messages or large blocks of data communication errors. This paper describes the AMCS theory of operation, AMCS fault modes, and AMCS system design methodology. Also, cost and timing information is presented. AMCS is being used and considered for several DOE and DOD facilities

  7. COMMUNICATIVE COMPETENCE AS THE SUBJECT OF EDUCATIONAL RESEARCH

    Directory of Open Access Journals (Sweden)

    Yuliya I. Аleyevskaya

    2016-09-01

    Full Text Available Introduction: the issue of development of the communicative competence is well studied in pedagogical theory and practice. Nevertheless there is no consensus among researchers regarding the interpretation of the notion. This fact determines the relevance of the subject in the context of the reform of the national higher education. The labour market puts forward increasing requirements to graduates’ adaption potential within the system “human – human”. This draws special attention to the problem of communicative co mpetence. Materials and Methods: the authors carried out a sociological research on the communicative component of the competence cluster among master’s degree students who specialise in pedagogical education in order to determine “the importance of weight indicators” of separate competencies. Results: the authors substantiate the necessity of broadening a communicative competence in conditions of transition to a multilevel system of higher education; define its essence and structure taking into account the generic unity of Bachelor’s and Master’s degree programmes. The article presents the informative content of communication components in accordance with the proposed structure of communicative competence, containing motivation-value-based, cognitive, activity-based, reflective and evaluative components. The authors show the potential of communicative competence in the context of the new federal state educational standards (FGOS VO 3+. Further the authors make analysis of the requirements set to graduates upon completion of undergraduate and graduate programmes in “Pedagogical Education”, specify the role of separate competencies in extending graduates’ communicative competence. Discussion and Conclusions: the results of the research presented in the article enable to specify the structure and content of the communicative competence of a university graduate, reflecting the willingness and ability to productive

    2008-11-01

    A conceptual framework for human communication, based on traditional biological ecology, is further developed. The difference between communication at the message and behavioural levels is emphasized. Empirical data are presented from various studies, showing that degree of satisfaction with communication is correlated with how close the outcome is to the memory of function prior to hearing impairment. We found no indication that hearing-impaired subjects overestimated their previous hearing or the hearing of normal-hearing people. Satisfaction was also correlated with the outcome and degree of fulfillment of expectations. It did not correlate with improvement of function. The concept of balance was presented and tested using a semi-quantitative approach. Several projects were presented in which the framework was applied: the hearing impaired as counsellor, choosing sides in unilateral deafness, a monitoring device for the deafblind, interaction between Swedish as a second language and hearing impairment, language development in hearing impaired children. By regarding hearing as a component of a communicative system, the perspective of audiological analysis and rehabilitation is broadened.

    Clinical communication failures are considered the leading cause of medical errors [1]. The complexity of the clinical culture and the significant variance in training and education levels form a challenge to enhancing communication within the clinical team. In order to improve communication, a comprehensive understanding of the overall communication process in health care is required. In an attempt to further understand clinical communication, we conducted a thorough methodology literature review to identify strengths and limitations of previous approaches [2]. Our research proposes a new data collection method to study the clinical communication activities among Intensive Care Unit (ICU) clinical teams with a primary focus on the attending physician. In this paper, we present the first ICU communication instrument, and, we introduce the use of database management system to aid in discovering patterns and associations within our ICU communications data repository.

    2010-10-01

    Telecommunications operators are well versed in deploying 2G and 3G wireless networks. These networks presently support the mobile business user and/or retail consumer wishing to place conventional voice calls and data connections. The electrical power industry has recently commenced transformation of its distribution networks by deploying smart monitoring and control devices throughout their networks. This evolution of the network into a `smart grid' has also motivated the need to deploy wireless technologies that bridge the communication gap between the smart devices and information technology systems. The requirements of these networks differ from traditional wireless networks that communications operators have deployed, which have thus far forced energy companies to consider deploying their own wireless networks. We present our experience in deploying wireless networks to support the smart grid and highlight the key properties of these networks. These characteristics include application awareness, support for large numbers of simultaneous cell connections, high service coverage and prioritized routing of data. We also outline our target blueprint architecture that may be useful to the industry in building wireless and fixed networks to support the smart grid. By observing our experiences, telecommunications operators and equipment manufacturers will be able to augment their current networks and products in a way that accommodates the needs of the emerging industry of smart grids and intelligent electrical networks.

    Full Text Available According to the ethno-cultural diversity, many educational and media basis in Iranian society are needed, in order to make good and healthy communication, in addition to the calm and peaceful interpersonal interaction. Cultural intolerance among diverse ethnics might cause to conflict, opposition, and discrimination and thus some negative affects on the majority beside the ethnic and religious minorities. Therefore, education, especially primary education in the age in which ethical and cultural schemas and assertions are shaped, is really important. This kind of intercultural instruction makes individuals aware of cultural differences and internalizes culture of tolerance. The educational system, which is based on justice and mutual respect, causes also to cultural dynamism and flexibility. Indeed, in this study, we attempt to reflect on the Constitution, as the basis of respect to minority (religious and ethnic; besides two cultural institutions, education and media, as the director in intercultural communication. Considered factors are the good citizenship, effective law system, and recognizing citizen rights.

  19. Most common misconceptions about informational communication technologies in education

    Pešikan Ana Ž.

    2016-01-01

    Full Text Available The aim of this paper is to discuss analytically the use of informational communication technologies (ICT in education so that education system could have greater benefits from its carefully planned use. In this paper we tried to show the specificity of the relations between education and ICT. Many things in that relation are accepted for granted, often without much analyzing. We selected some of typical misconceptions which contribute to erroneous ideas about education and ICT relation resulting in limited opportunities for using up new technologies in education. When analyzing ICT in education there is no room for the question whether to use new technologies in the teaching/ learning process or not, but when, why and how to use them. In order to bring these decisions and use ICT potentials for educational purposes, thorough understanding of the nature of teaching and learning is necessary. Education should not be just a buyer or a prudent user of numerous ICT possibilities but it should carefully and thoughtfully transform the teaching/learning process in order equip future and nowadays citizens with skills necessary for living and working in the environment with significantly changed technology. Much more researching and theoretical work is needed in order to fully understand how ICT really influences the learning process and how to use that influence in order to enhance the quality of education.

    Hwu, Shian U.; Desilva, Kanishka; Sham, Catherine C.

    2010-01-01

    The Communication Systems Simulation Laboratory (CSSL) at the NASA Johnson Space Center is tasked to perform spacecraft and ground network communication system simulations, design validation, and performance verification. The CSSL has developed simulation tools that model spacecraft communication systems and the space and ground environment in which the tools operate. In this paper, a spacecraft communication system with multiple arrays is simulated. Multiple array combined technique is used to increase the radio frequency coverage and data rate performance. The technique is to achieve phase coherence among the phased arrays to combine the signals at the targeting receiver constructively. There are many technical challenges in spacecraft integration with a high transmit power communication system. The array combining technique can improve the communication system data rate and coverage performances without increasing the system transmit power requirements. Example simulation results indicate significant performance improvement can be achieved with phase coherence implementation.

    Transitioning from twenty-five years of space communication system architecting, engineering and development to creating and marketing of commercial communication system hardware and software products is no simple task for small, high-tech system engineering companies whose major source of revenue has been the U.S. Government. Yet, many small businesses are faced with this onerous and perplexing task. The purpose of this talk/paper is to present one small business (LinCom) approach to taking advantage of the systems engineering expertise and knowledge captured in physical neural networks and simulation software by supporting numerous National Aeronautics and Space Administration (NASA) and the Department of Defense (DoD) projects, e.g., Space Shuttle, TDRSS, Space Station, DCSC, Milstar, etc. The innovative ingredients needed for a systems house to transition to a wireless communication system products house that supports personal communication services and networks (PCS and PCN) development in a global economy will be discussed. Efficient methods for using past government sponsored space system research and development to transition to VLSI communication chip set products will be presented along with notions of how synergy between government and industry can be maintained to benefit both parties.

    Information and communication technology (ICT) has brought many changes in medical education and practice in the last couple of decades. Teaching and learning medicine particularly has gone under profound changes due to computer technologies, and medical schools around the world have invested heavily either in new computer technologies or in the process of adapting to this technological revolution. In order to catch up with the rest of the world, developing countries need to research their options in adapting to new computer technologies. This descriptive survey study was designed to assess medical students' computer and Internet skills and their attitude toward ICT. Research findings showed that the mean score of self-perceived computer knowledge for male students in general was greater than for female students. Also, students who had participated in various prior computer workshops, had access to computer, Internet, and e-mail, and frequently checked their e-mail had higher mean of self-perceived knowledge and skill score. Finally, students with positive attitude toward ICT scored their computer knowledge higher than those who had no opinion. The results have confirmed that the medical schools, particularly in developing countries, need to bring fundamental changes such as curriculum modification in order to integrate ICT into medical education, creating essential infrastructure for ICT use in medical education and practice, and structured computer training for faculty and students.

  7. Communication architecture of an early warning system

    Directory of Open Access Journals (Sweden)

    M. Angermann

    2010-11-01

    Full Text Available This article discusses aspects of communication architecture for early warning systems (EWS in general and gives details of the specific communication architecture of an early warning system against tsunamis. While its sensors are the "eyes and ears" of a warning system and enable the system to sense physical effects, its communication links and terminals are its "nerves and mouth" which transport measurements and estimates within the system and eventually warnings towards the affected population. Designing the communication architecture of an EWS against tsunamis is particularly challenging. Its sensors are typically very heterogeneous and spread several thousand kilometers apart. They are often located in remote areas and belong to different organizations. Similarly, the geographic spread of the potentially affected population is wide. Moreover, a failure to deliver a warning has fatal consequences. Yet, the communication infrastructure is likely to be affected by the disaster itself. Based on an analysis of the criticality, vulnerability and availability of communication means, we describe the design and implementation of a communication system that employs both terrestrial and satellite communication links. We believe that many of the issues we encountered during our work in the GITEWS project (German Indonesian Tsunami Early Warning System, Rudloff et al., 2009 on the design and implementation communication architecture are also relevant for other types of warning systems. With this article, we intend to share our insights and lessons learned.

  8. Computational Interpersonal Communication: Communication Studies and Spoken Dialogue Systems

    Directory of Open Access Journals (Sweden)

    David J. Gunkel

    2016-09-01

    Full Text Available With the advent of spoken dialogue systems (SDS, communication can no longer be considered a human-to-human transaction. It now involves machines. These mechanisms are not just a medium through which human messages pass, but now occupy the position of the other in social interactions. But the development of robust and efficient conversational agents is not just an engineering challenge. It also depends on research in human conversational behavior. It is the thesis of this paper that communication studies is best situated to respond to this need. The paper argues: 1 that research in communication can supply the information necessary to respond to and resolve many of the open problems in SDS engineering, and 2 that the development of SDS applications can provide the discipline of communication with unique opportunities to test extant theory and verify experimental results. We call this new area of interdisciplinary collaboration “computational interpersonal communication” (CIC

  10. Phase-Modulated Optical Communication Systems

    CERN Document Server

    Ho, Keang-Po

    2005-01-01

    Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored. As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics: The transmitter and receiver for phase-modulated coherent lightwave systems Method for performance analysis o...

  18. Economics of satellite communications systems

    Science.gov (United States)

    Pritchard, Wilbur L.

    This paper is partly a tutorial, telling systematically how one goes about calculating the total annual costs of a satellite communications system, and partly the expression of some original ideas on the choice of parameters so as to minimize these costs. The calculation of costs can be divided into two broad categories. The first is technical and is concerned with estimating what particular equipment will cost and what will be the annual expense to maintain and operate it. One starts in the estimation of any new system by listing the principal items of equipment, such as satellites, earth stations of various sizes and functions, telemetry and tracking equipment and terrestrial interfaces, and then estimating how much each item will cost. Methods are presented for generating such estimates, based on a knowledge of the gross parameters, such as antenna size, coverage area, transmitter power and information rate. These parameters determine the system performance and it is usually possible, knowing them, to estimate the costs of the equipment rather well. Some formulae based on regression analyses are presented. Methods are then given for estimating closely related expenses, such as maintenance and operation, and then an approximate method is developed for estimating terrestrial interconnection costs. It is pointed out that in specific cases when tariff and geographical information are available, it is usually better to work with specific data, but nonetheless it is often desirable, especially in global system estimating, to approximate these interconnect costs without recourse to individual tariffs. The procedure results in a set of costs for the purchase of equipment and its maintenance, and a schedule of payments. Some payments will be incurred during the manufacture of the satellite and before any systems operation, but many will not be incurred until the system is no longer in use, e.g. incentives. In any case, with the methods presented in the first section, one

  20. Integrating education, training and communication for public involvement in EIA

    International Nuclear Information System (INIS)

    Oprea, Irina; Oprea, Marcel; Guta, Cornelia; Guta, Vasilica

    2003-01-01

    We are going towards a globalized world, this involving the integration of every activity and every person. The public involvement in the development process is evident, taking into account that any objective will affect the people and the negative feedback could influence the result of the investment. Generally the public could be influenced by amplification of negative evaluated consequences, resulting psychosocial effects leading to illness or anxieties. This problem will be resolved by the public access to information provided by experts. A real-time interactive communication system is proposed as an open tool in order to facilitate decision-making by access to rapid and reliable information. The main task of the system is to collect, process, display and exchange the information relative to environmental impact assessment (EIA), to provide assistance, to receive specific opinions, being also proposed for public understanding of the field. The education and training integration will mitigate the barriers, which may inhibit the interaction and communication process. To increase learning will assure specialists-public interaction and a good information flow for knowledge exchange. The paper will outline key approaches in reaching agreement on the people educational process importance. The impact of development will be available to the public revealing the positive consequences, such as increased employment and income. An effective way to avoid negative reactions consists of the extensive consultation to identify the concerns and needs of the public, the access to suggestive and attractive programs for education and training. The system is developed as a modern information module, integrated into complex international management systems. It can be placed everywhere, everybody could access the facilities for education, world experience and training. Providing a real-time response to citizen concerns, the system represents an economic and rapid way to mitigate the

    The purpose of this study was to examine the communication dynamics leading to the adoption of new attitudes and cognitions in health education sessions. We examined the verbal interactions at work in persuasive communication in 16 health education sessions. The study found that the medical expertise of the educator and the initial level of commitment of the participants had a positive effect on adherence to recommendations. However, persuasive communication in health education sessions appears to involve a paradoxical process in which criticism of the message can go hand in hand with the expression of an intention to implement new risk-reducing behaviors.

    2017-01-01

    Full Text Available Railway, subway, airplane, and other transportation systems have drawn an increasing interest on the use of wireless communications for critical and noncritical services to improve performance, reliability, and passengers experience. Smart transportation systems require the use of critical communications for operation and control, and wideband services can be provided using noncritical communications. High speed train (HST is one of the best test cases for the analysis of communication links and specification of the general requirements for train control and supervision, passenger communications, and onboard and infrastructure wireless sensors. In this paper, we analyze in detail critical and noncritical networks mainly using the HST as a test case. First, the different types of links for smart rail transportation are described, specifying the main requirements of the transportation systems, communications, and their applications for different services. Then, we propose a network architecture and requirements of the communication technologies for critical and noncritical data. Finally, an analysis is made for the future technologies, including the fifth-generation (5G communications, millimeter wave (mmWave, terahertz (THz, and satellites for critical and high-capacity communications in transportation.

    International Nuclear Information System (INIS)

    Capel, A.C.; Yan, G.

    1980-01-01

    One of the promises of distributed systems is the ability to design each process function largely independently of the others, and in many cases locate the resulting hardware in close proximity to the application. The communications architecture for such systems should be approached in the same way, using separable communications facilities to meet individual sets of requirements while at the same time reducing the interactions between functions. Where complete physical separation is not feasible and hardware resource sharing is required, the protocols should be designed emphasizing the logical separation of communication paths. This paper discusses the different types of communications for process control applictions and the parameters which need to be characterized in designing separable communications for distributed systems.

    2013-01-01

    In the work of a physician, not only knowledge, and professional skills (technical/hard) are important, but also psychosocial skills (relational/soft). The primary goal of the presented research was evaluation of the level (study of the state) of communication competences of physicians and determination of the factors on which this level depends. An additional goal was analysis of the needs and educational possibilities within the existing models of education in the area of interpersonal communication provided in Medical Universities in Poland. Information about educational curricula available on the websites of 12 Medical Universities in Poland were compared. The self-designed questionnaire and adjective check list were subject to standardization from the aspect of reliability and validity. The study groups included 1) occupationally-active physicians (185 respondents) employed in outpatient departments and hospitals, who were covered by a pre-graduate standard educational programme and not trained in interpersonal communication skills as part of their continuing education; 2) medical students covered by a standard educational programme (246 respondents). The conducted analysis of the educational curricula showed a very narrow scope of problems concerning professional medical communication. The results indicating the general state of respondents' communication competences within all aspects (motivation, skills, knowledge) were relatively low. That clearly indicated an inadequate educational model (students), and lack of post-graduate training in the area of professional medical communication (physicians). The education of students of medicine should cover selected classes within the scope of professional communication competences. These classes should be based on the systemically designed training of skills. The patterning by students of the relations attitudes observed in practising physicians is insufficient. It is necessary to apply a methodical evaluation of

  2. System Design for Nano-Network Communications

    Science.gov (United States)

    ShahMohammadian, Hoda

    The potential applications of nanotechnology in a wide range of areas necessities nano-networking research. Nano-networking is a new type of networking which has emerged by applying nanotechnology to communication theory. Therefore, this dissertation presents a framework for physical layer communications in a nano-network and addresses some of the pressing unsolved challenges in designing a molecular communication system. The contribution of this dissertation is proposing well-justified models for signal propagation, noise sources, optimum receiver design and synchronization in molecular communication channels. The design of any communication system is primarily based on the signal propagation channel and noise models. Using the Brownian motion and advection molecular statistics, separate signal propagation and noise models are presented for diffusion-based and flow-based molecular communication channels. It is shown that the corrupting noise of molecular channels is uncorrelated and non-stationary with a signal dependent magnitude. The next key component of any communication system is the reception and detection process. This dissertation provides a detailed analysis of the effect of the ligand-receptor binding mechanism on the received signal, and develops the first optimal receiver design for molecular communications. The bit error rate performance of the proposed receiver is evaluated and the impact of medium motion on the receiver performance is investigated. Another important feature of any communication system is synchronization. In this dissertation, the first blind synchronization algorithm is presented for the molecular communication channels. The proposed algorithm uses a non-decision directed maximum likelihood criterion for estimating the channel delay. The Cramer-Rao lower bound is also derived and the performance of the proposed synchronization algorithm is evaluated by investigating its mean square error.

    The International Space Station (ISS) Early Communications System (ECOMM) was a Johnson Space Center (JSC) Avionic Systems Division (ASD) in-house developed communication system to provide early communications between the ISS and the Mission Control Center-Houston (MCC-H). This system allows for low rate commands (link rate of 6 kbps) to be transmitted through the Tracking and Data Relay Satellite System (TDRSS) from MCC-H to the ISS using TDRSS's S-band Single Access Forward (SSA/) link service. This system also allows for low rate telemetry (link rate of 20.48 kbps) to be transmitted from ISS to MCC-H through the TDRSS using TDRSS's S-band Single Access Return (SSAR) link service. In addition this system supports a JSC developed Onboard Communications Adapter (OCA) that allows for a two-way data exchange of 128 kbps between MCC-H and the ISS through TDRSS. This OCA data can be digital video/audio (two-way videoconference), and/or file transfers, and/or "white board". The key components of the system, the data formats used by the system to insure compatibility with the future ISS S-Band System, as well as how other vehicles may be able to use this system for their needs are discussed in this paper.

    Full Text Available Using of Marketing Communication for Distance Education Institutions R. Ayhan YILMAZ, Ph.DAnadolu UniversityCommunication Sciences FacultyEskisehir, TURKEY INTRODUCTION Because of increased competition for scarce resources, marketing has become an important activity of many nonprofit organizations. Higher education institutions, as one of these nonprofit organizations, provide us with excellent examples of this trend (Hayes, 1991. The marketing of higher education has received a tremendous amount of emphasis and attention. Distance education (DE has become an accepted form of education and has been gaining widespread popularity in recent years. Marketing concept has been gaining importance in distance education sector throughout the world. The factors responsible for this are self-support policies, increasing competitiveness in the marketplace, rising customer expectations, widening access to education etc (Gupta, 2005. More than 70 countries are offering educational programmes through distance education all over the world today (Sudalaimuthu, Visited 3rd March, 2005, http://www.ignou.ac.in/Theme-1/S.%20Sudalaimuthu.htm Because of flexibility, convenience and opportunity, distance education is becoming so popular, profitable and vital. By 2005, % 90 American universities will offer at least one course online. Currently about 3 million Americans are distance education students (Gonzales, 2002. In this paper, I will discuss the following questions: What is the brief history and changing environment of distance education? Which marketing communication tools are used in DE institutions? What benefits does marketing communications provide to DE institutions? BRIEF HISTORY OF DISTANCE EDUCATION Distance education began as a correspondence course in the 1800's. Between the years of 1950 and 1960, it serviced as video conferencing. From 1950 to 1980, teleconferencing was used. Since 1990 to present day, web-based instruction have been using in distance

    2016-06-01

    Communication skills are essential to medical training and have lasting effects on patient satisfaction and adherence rates. However, relatively little is reported in the literature identifying how communication is taught in the context of residency education. Our goal was to determine current practices in communication curricula across family medicine residency programs. Behavioral scientists and program directors in US family medicine residencies were surveyed via email and professional organization listservs. Questions included whether programs use a standardized communication model, methods used for teaching communication, hours devoted to teaching communication, as well as strengths and areas for improvement in their program. Analysis identified response frequencies and ranges complemented by analysis of narrative comments. A total of 204 programs out of 458 family medicine residency training sites responded (45%), with 48 out of 50 US states represented. The majority of respondents were behavioral scientists. Seventy-five percent of programs identified using a standard communication model; Mauksch's patient-centered observation model (34%) was most often used. Training programs generally dedicated more time to experiential teaching methods (video review, work with simulated patients, role plays, small groups, and direct observation of patient encounters) than to lectures (62% of time and 24% of time, respectively). The amount of time dedicated to communication education varied across programs (average of 25 hours per year). Respondent comments suggest that time dedicated to communication education and having a formal curriculum in place are most valued by educators. This study provides a picture of how communication skills teaching is conducted in US family medicine residency programs. These findings can provide a comparative reference and rationale for residency programs seeking to evaluate their current approaches to communication skills teaching and

    An integrated computer-based communications system uses multiple computers for the high speed transmission, storage, enhancement and display for medical information. Interconnected by a network such as coaxial and fiberoptic cables or microwave stations, the system would provide integrated communications throughout a satellite medical environment. As the availability of proven PACS components becomes a commercial reality, migratory expansion of PACS within the radiology clinical, educational and research areas will be possible. When the PACS is integrated with hospital, radiology and medical school information systems it provides the image component of a total medical information system. Current PACS efforts are on a research basis including the development of prototype systems. This paper provides an overview of implementation strategies. Issues to be discussed include PACS research objectives, typical implementation methods, and a review of interactions between PACS and radiology information systems (RIS) and hospital information systems

    Nonemergent communications between nursing staff and residents often occur randomly throughout the workday at teaching institutions, resulting in inefficiency and interruptions of scheduled resident educational conferences or periods of overnight rest. The aim of this study was to determine whether a quality improvement communication strategy can reduce interruptive notifications during scheduled resident didactic sessions. We conducted a prospective, mixed-methods trial of a communication strategy between nurses and residents in 3 neurology units of an academic institution. We measured content and volume of notifications from nurses to residents during scheduled conferences and overnight and categorized these notifications according to levels of urgency. We implemented an intervention requiring multidisciplinary evening work rounds between the on-call resident and charge nurse and batching of nonemergent communications. Survey data were collected. The total census during the 6-month study period was 728 patients. Of the 704 resident-reported nursing notifications, 50% could be safely deferred until change of shift. After the intervention, there was a 52% decrement of notifications (0.52 vs 0.25 notifications per patient, P communication system reduced interruptive calls during educational conferences and overnight by half. This intervention was perceived as safe and effective and resulted in higher satisfaction among participants.

    The role of the pharmacist as a "communicator" of information and advice between patients, other healthcare practitioners, and the community is recognized as a vital component of the responsibilities of a practicing pharmacist. Pharmacy education is changing to reflect this, although the difficulty is in designing a curriculum that is capable of equipping students with the necessary knowledge and skills, using activities that are effective in promoting communication competency. The objective of this review was to identify published, peer-reviewed articles concerning communication training in pharmacy education programs, and describe which communication skills the structured learning activities aimed to improve and how these learning activities were assessed. A systematic literature search was conducted and the articles found were analyzed and divided into categories based on specific communication skills taught and type of learning activity used. Oral interpersonal communication skills targeted at patients were the most common skill-type described, followed by clinical writing skills. Common teaching methods included simulated and standardized patient interactions and pharmacy practice experience courses. Most educational interventions were assessed by subjective measures. Many interventions were described as fragments, in isolation of other learning activities that took place in a course, which impedes complete analysis of study results. To succeed in communication training, integration between different learning activities and progression within pharmacy educations are important.

    Load controllers available today can measure AC system frequency and react to frequency deviations. A system operator can communicate to frequency sensitive loads by changing the set-points of the system’s dispatchable frequency regulation resources. Explicitly signaling system state by generating...... off-nominal system frequency values is a novel narrowband broadcast communications channel between system operators and frequency sensitive distributed energy resources (FS-DER). The feasibility of the proposed system is evaluated on an existing island power system in Denmark. This study shows...... that within standard frequency quality constraints, 4 distinct symbols are feasible on the island. However, the overarching imperative of system stability prevents the symbols from having arbitrary meanings. Higher frequency values must translate into greater consumption from loads, and vice versa. Within...

    1999-01-01

    Safety Support System (SSS) is a computerized operator support system for nuclear power plants, which is now under development. The concept of SSS covers 1) earlier detection of failure symptom and prediction of its influence to the plant operation, 2) improved transparency and robustness of plant control systems, 3) advanced human-machine interface and communication. The authors have been working on the third concept and proposed a remote mobile communication system called Plant Communication System (PCS). PCS aims to realize convenient communication between main control room and other areas such as plant local areas and site offices, using Personal Handyphone System (PHS) and wireless LAN (Local Area Network). PCS can transmit not only data but also graphic displays and dynamic video displays between the main control room and plant local areas. MPEG4 (Moving Picture Experts Group 4) technology is utilized in video data compression and decompression. The authors have developed the special multiplexing unit that connects PHS Cell Stations (CSs) and exiting coaxial cables. Voice recognition and announcement capability is also realized in the system, which enables verbal retrieval of information in the computer systems in the main control room from local areas.

    Vaudan, Cristina; Sporrong, Sofia Kälvemark

    2013-01-01

    The role of the pharmacist as a “communicator” of information and advice between patients, other healthcare practitioners, and the community is recognized as a vital component of the responsibilities of a practicing pharmacist. Pharmacy education is changing to reflect this, although the difficulty is in designing a curriculum that is capable of equipping students with the necessary knowledge and skills, using activities that are effective in promoting communication competency. The objective of this review was to identify published, peer-reviewed articles concerning communication training in pharmacy education programs, and describe which communication skills the structured learning activities aimed to improve and how these learning activities were assessed. A systematic literature search was conducted and the articles found were analyzed and divided into categories based on specific communication skills taught and type of learning activity used. Oral interpersonal communication skills targeted at patients were the most common skill-type described, followed by clinical writing skills. Common teaching methods included simulated and standardized patient interactions and pharmacy practice experience courses. Most educational interventions were assessed by subjective measures. Many interventions were described as fragments, in isolation of other learning activities that took place in a course, which impedes complete analysis of study results. To succeed in communication training, integration between different learning activities and progression within pharmacy educations are important. PMID:23519011

  16. How to bootstrap a human communication system.

    Science.gov (United States)

    Fay, Nicolas; Arbib, Michael; Garrod, Simon

    2013-01-01

    How might a human communication system be bootstrapped in the absence of conventional language? We argue that motivated signs play an important role (i.e., signs that are linked to meaning by structural resemblance or by natural association). An experimental study is then reported in which participants try to communicate a range of pre-specified items to a partner using repeated non-linguistic vocalization, repeated gesture, or repeated non-linguistic vocalization plus gesture (but without using their existing language system). Gesture proved more effective (measured by communication success) and more efficient (measured by the time taken to communicate) than non-linguistic vocalization across a range of item categories (emotion, object, and action). Combining gesture and vocalization did not improve performance beyond gesture alone. We experimentally demonstrate that gesture is a more effective means of bootstrapping a human communication system. We argue that gesture outperforms non-linguistic vocalization because it lends itself more naturally to the production of motivated signs. © 2013 Cognitive Science Society, Inc.

  18. Rate Adaptive OFDMA Communication Systems

    International Nuclear Information System (INIS)

    Abdelhakim, M.M.M.

    2009-01-01

    Due to the varying nature of the wireless channels, adapting the transmission parameters, such as code rate, modulation order and power, in response to the channel variations provides a significant improvement in the system performance. In the OFDM systems, Per-Frame adaptation (PFA) can be employed where the transmission variables are fixed over a given frame and may change from one frame to the other. Subband (tile) loading offers more degrees of adaptation such that each group of carriers (subband) uses the same transmission parameters and different subbands may use different parameters. Changing the code rate for each tile in the same frame, results in transmitting multiple codewords (MCWs) for a single frame. In this thesis a scheme is proposed for adaptively changing the code rate of coded OFDMA systems via changing the puncturing rate within a single codeword (SCW). In the proposed structure, the data is encoded with the lowest available code rate then it is divided among the different tiles where it is punctured adaptively based on some measure of the channel quality for each tile. The proposed scheme is compared against using multiple codewords (MCWs) where the different code rates for the tiles are obtained using separate encoding processes. For bit interleaved coded modulation architecture two novel interleaving methods are proposed, namely the puncturing dependant interleaver (PDI) and interleaved puncturing (IntP), which provide larger interleaving depth. In the PDI method the coded bits with the same rate over different tiles are grouped for interleaving. In IntP structure the interleaving is performed prior to puncturing. The performance of the adaptive puncturing technique is investigated under constant bit rate constraint and variable bit rate. Two different adaptive modulation and coding (AMC) selection methods are examined for variable bit rate adaptive system. The first is a recursive scheme that operates directly on the SNR whereas the second

  20. PACS: Picture Archiving and Communication Systems

    International Nuclear Information System (INIS)

    Gell, G.; Schneider, G.H.; Becker, M.; Wiltgen, M.

    1988-01-01

    A growing number of medical imaging modalities produces images that are initially calculated and stored as digital information in a computer. For diagnosis, archiving and communication a hardcopy (usually on X-ray film) is produced from these data. It is estimated that in 1995 about 80% of all imaging procedures will generate digital images. This trend leads to the development of systems, where the X-ray film is not only replaced in his function as a radiation detector, but also in his other functions as the medium for image presentation, image communication and image archiving. In short, one wants a completely digital picture archiving and communication system (PACS). The rationale behind PACS efforts is to achieve better functionality and to save costs, mainly by reducing the consumption of expensive X-ray films and the need for storage space for film archives. 7 refs., 2 figs.

    Physician to physician communication is essential for the transfer of ideas, surgical experience, and education. Social networks and online video educational contents have grown exponentially in recent years changing the interaction among physicians. Social media platforms can improve physician-to-physician communication mostly through video education and social networking. There are several online video platforms for orthopedic surgery with educational content on diagnosis, treatment, outcomes, and surgical technique. Social networking instead is mostly centered on sharing of data, discussion of confidential topics, and job seeking. Quality of educational contents and data confidentiality represent the major drawbacks of these platforms. Orthopedic surgeons must be aware that the quality of the videos should be better controlled and regulated to avoid inaccurate information that may have a significant impact especially on trainees that are more prone to use this type of resources. Sharing of data and discussion of confidential topics should be extremely secure according the HIPAA regulations in order to protect patients' confidentiality.

    Philip, Susan; Manias, Elizabeth; Woodward-Kron, Robyn

    2015-09-01

    To understand the intercultural communication experiences and associated communication training needs of overseas qualified nurses in the Australian healthcare system from the unique perspectives of nurse educators teaching in accredited bridging programmes. Overseas qualified nurses are an integral part of the nursing workforce in migration destination countries. Communication training needs are more complex when there are cultural, ethnic and language differences between nurses, other health professionals and patients. A qualitative, exploratory research design using semi-structured interviews. All (nine) organisations involved in conducting the Australian Health Practitioner Regulation Agency approved preregistration bridging programmes for overseas qualified nurses within the state of Victoria, Australia, were involved in the study. Participants were 12 nurse educators employed in these organisations. Thematic analysis was undertaken. Three macro themes emerged about the overseas qualified nurses' intercultural communication: (1) pre-existing barriers and enablers to intercultural communication, for example, nurses' reluctance to engage in communicative strategies that build rapport with patients, (2) transitional behaviours and impact on communication, including maintenance of perceived cultural hierarchies between health professionals and (3) development of communicative competence, including expanding one's repertoire of conversational gambits. The findings point to the domains and causes of communication challenges facing overseas qualified nurses in new healthcare settings as well as strategies that the nurse educators and nurses can adopt. Communication cannot be merely regarded as a skill that can be taught in a didactic programme. Comprehensive understanding is needed about the sociocultural dimensions of these nurses' orientation, which can impact on how they communicate in their new healthcare settings. The findings can act as triggers for discussion

The remote terminal applies a direct sequence spreading code to a data signal at a spreading factor to provide a direct sequence spread spectrum (DSSS) signal. The DSSS signal is transmitted over the communication channel to the base terminal which can be configured to despread the received DSSS signal by a spreading factor matching the spreading factor utilized to spread the data signal. The remote terminal and base terminal can dynamically vary the matching spreading factors to adjust the data rate based on an estimation of operating quality over time between the remote terminal and base terminal such that the amount of data being transmitted is substantially maximized while providing a specified quality of service.

    This paper discusses a planned study to evaluate the commercial attractiveness of high power communication satellites and assesses the attributes of both conventional photovoltaic and reactor power systems. These high power satellites can play a vital role in assuring availability of universally accessible, wide bandwidth communications, for high definition TV, super computer networks and other services. Satellites are ideally suited to provide the wide bandwidths and data rates required and are unique in the ability to provide services directly to the users. As new or relocated markets arise, satellites offer a flexibility that conventional distribution services cannot match, and it is no longer necessary to be near population centers to take advantage of the telecommunication revolution. The geopolitical implications of these substantially enhanced communications capabilities can be significant.

    Achieving English language proficiency, while key to successful adaptation to a new country for internationally educated nurses (IENs), has presented more difficulties for them and for educators than previously recognized. Professional communication within a culturally diverse client population and maintaining collaborative relationships between nurses and other team members were perceived as new challenges for IENs. Learning an additional language is a long-term, multistage process that must also incorporate social and cultural aspects of the local society and the profession. This article provides a descriptive review of current research literature pertaining to English language challenges, with a focus on oral language, experienced by IENs. Educational strategies for teaching technical language skills as well as the socio-pragmatics of professional communication within nursing programs are emphasized. Bridging education programs must not only develop students'academic language proficiency but also their ability to enter the workforce with the kind of communication skills that are increasingly highlighted by employers as essential attributes. The results of this review are intended to facilitate a clearer understanding of the English language and communication challenges experienced by IENs and identify the implications for designing effective educational programs. © The Author(s) 2014.

    Modern communications demands have been steadily growing not only in size, but sophistication. Phone calls over copper wires have evolved into high definition video conferencing over optical fibers, and wireless internet browsing. The technology used to meet these demands is under constant pressure to provide increased capacity, speed, and efficiency, all with reduced size and cost. Various MEMS technologies have shown great promise for meeting these challenges by extending the performance of conventional circuitry and introducing radical new systems approaches. A variety of strategic MEMS structures including various cost-effective free-space optics and high-Q RF components are described, along with related practical implementation issues. These components are rapidly becoming essential for enabling the development of progressive new communications systems technologies including all-optical networks, and low cost multi-system wireless terminals and basestations.

    Full Text Available Technological advances brought applications of innovations to education. Conventional education increasingly flourishes with new technologies accompanied by more learner active environments. In this continuum, there are learners preferring self-learning. Traditional learning materials yield attractive, motivating and technologically enhanced learning materials. The QR (Quick Response Codes are one of these innovations. The aim of this study is to redesign a lesson unit supported with QR Codes and to get the learner views about the redesigned material. For this purpose, the redesigned lesson unit was delivered to 15 learners in Balıkesir University in the academic year of 2013-2014. The learners were asked to study the material. The learners who had smart phones and Internet access were chosen for the study. To provide sectional diversity, three groups were created. The group learners were from Faculty of Education, Faculty of Science and Literature and Faculty of Engineering. After the semi-structured interviews were held, the learners were asked about their pre-knowledge about QR Codes, QR Codes’ contribution to learning, difficulties with using QR Codes about and design issues. Descriptive data analysis was used in the study. The findings were interpreted on the basis of Theory of Diffusion of Innovations and Theory of Uses and Gratifications. After the research, the themes found were awareness of QR Code, types of QR Codes and applications, contributions to learning, and proliferation of QR Codes. Generally, the learners participating in the study reported that they were aware of QR Codes; that they could use the QR Codes; and that using QR Codes in education was useful. They also expressed that such features as visual elements, attractiveness and direct routing had positive impact on learning. In addition, they generally mentioned that they did not have any difficulty using QR Codes; that they liked the design; and that the content should

    The globalization and free trade between countries and nations has created demands for the knowledge and skills in the area of intercultural interaction and transaction. Intercultural Communication Competences (ICC) is one of the capabilities that need to be possessed by workers and professionals who want to have a bigger role in the business and industries in international level. Vocational education institutions are demanded to provide their students with a certain degree of competences in multicultural interaction and communication. This paper aims to address the effectiveness of trainings in a vocational education institution in equipping its students with the intercultural communication skills. Using a sample of students from the ISP Cruiseship and Hotel School Surakarta, Central Java, this study will analyses the differences of ICC between groups of students who have undergone various forms of training in intercultural communication, in order to determine the effectiveness of the training in equipping the students with the necessary intercultural communication skills. The study incorporates a quantitative approach, using survey method. The data will be analyzed using descriptive statistics and analysis of variations between groups. The result shows that the intercultural communication training increase the level of ICC especially in the intercultural confidence dimension.

    This report describes the Orbiter Interface Unit (OIU) and the Early Communication System (ECOMM), which are systems of electronic hardware and software that serve as the primary communication links for the International Space Station (ISS). When a space shuttle is at or near the ISS during assembly and resupply missions, the OIU sends groundor crew-initiated commands from the space shuttle to the ISS and relays telemetry from the ISS to the space shuttle s payload data systems. The shuttle then forwards the telemetry to the ground. In the absence of a space shuttle, the ECOMM handles communications between the ISS and Johnson Space Center via the Tracking and Data Relay Satellite System (TDRSS). Innovative features described in the report include (1) a "smart data-buffering algorithm that helps to preserve synchronization (and thereby minimize loss) of telemetric data between the OIU and the space-shuttle payload data interleaver; (2) an ECOMM antenna-autotracking algorithm that selects whichever of two phased-array antennas gives the best TDRSS signal and electronically steers that antenna to track the TDRSS source; and (3) an ECOMM radiation-latchup controller, which detects an abrupt increase in current indicative of radiation-induced latchup and temporarily turns off power to clear the latchup, restoring power after the charge dissipates.

    To determine the impact of simulations using an alternative method of communication on students' satisfaction, attitudes, confidence, and performance related to interprofessional communication. One hundred sixty-three pharmacy students participated in a required applications-based capstone course. Students were randomly assigned to one of three interprofessional education (IPE) simulations with other health professions students using communication methods such as telephone, e-mail, and video conferencing. Pharmacy students completed a validated survey instrument, Attitude Toward Healthcare Teams Scale (ATHCTS) prior to and after course participation. Significant positive changes occurred for 5 out of 20 items. Written reflection papers and student satisfaction surveys completed after participation showed positive themes and satisfaction. Course instructors evaluated student performance using rubrics for formative feedback. Implementation of IPE simulations using various methods of communication technology is an effective way for pharmacy schools to incorporate IPE into their curriculum.

    The unique partnership between the NASA New Horizons education/communications and public affairs programs tapped into the excitement of visiting an unexplored planet in a new region of the solar system - resulting in unprecedented public participation in and coverage of a planetary mission. With a range of hands-on learning experiences, Web materials and online , the program provided opportunities for students, educators, museums, science centers, the media, Web surfers and other members of the public to ride along on the first mission to Pluto and the Kuiper Belt. The programs leveraged resources, materials and expertise to address a wide range of traditional and nontraditional audiences while providing consistent messages and information on this historic NASA endeavor. The E/C program included a variety of formal lesson plans and learning materials — based on New Horizons science and engineering goals, and aligned with National Research Council's National Science Education Standards — that continue to help students in grades K-12 learn more about science, technology, engineering and mathematics. College students designed and built an actual flight instrument on New Horizons and held internships with the spacecraft integration and test team. New Horizons E/C programs went well beyond the classroom, from a chance for people to send their names to Pluto on board the New Horizons spacecraft before launch, to opportunities for the public to access milestone events and the first-ever close-up views of Pluto in places such as museums, science centers and libraries, TV and the Web — as well as thousands who attended interactive "Plutopalooza" road shows across the country. Teamed with E/C was the public affairs strategy to communicate New Horizons news and messages to media, mission stakeholders, the scientific community and the public. These messages include various aspects of New Horizons, including the progress of the mission and key milestones and achievements

    Fay, Nicolas; Garrod, Simon; Roberts, Leo; Swoboda, Nik

    2010-04-01

    This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants' horizontal, pair-wise interactions led "bottom up" to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community-evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.

  9. The Peace System - As a self-referential communication system

    Directory of Open Access Journals (Sweden)

    Gorm Harste

    2013-11-01

    Full Text Available Peace communication as diplomatic communication is an often neglected phenomenon in social and political theory that concerns problems of international order, justice and peace. Political philosophy seldom embarks on the theme with more than a few comments. Yet, throughout history, diplomacy has a strong record not only for negotiations but also for social learning processes about communication codes. Many codes of respect, trust, expression and listening have a top-down history from aristocratic circles to broader social layers. However, the article argues that communication codes of peace developed in opposition to violence and war exactly when they transgress dividing lines allowing for cross-cultural and even cross-stratified communication. The article’s main point is to describe how such communication codes about peace and diplomacy can be described in recent social theory of communication, and to get some added value in this respect, Niklas Luhmann’s theory of self-referential communication systems has been applied.

    2014-04-01

    Full Text Available At the University of Bergen in Norway, educating students to use computer models and to think systemically about social and economic problems began in the 1970s. The International Masters Program in System Dynamics was established in 1995, and a Ph.D. program began a few years later. Student enrolment doubled in 2010 with the establishment of the European Master Program in System Dynamics. International diversity has been a hallmark of the Bergen program; each year, students come from about 30 different countries and more than 95% of the degrees have been awarded to students from outside of Norway. However, a Bergen systems education is not confined to a classroom in Norway. Projects in developing countries, emerging economies, and developed countries have taken the systems perspective and modeling tools on the road and, increasingly, online. Whatever the delivery mode, the goal is the same: capacity building among international students, planners and managers, and local stakeholders. This paper describes the Bergen program and its impact on systems thinking and modeling throughout the world.

    2012-01-01

    Full Text Available The aim of this paper is to explain the calendar systems and their role in teaching deaf-blind children. Deaf-blind persons belong to a group of multiple disabled persons. This disability should not be observed as a simple composite of visual and hearing impairments, but as a combination of sensory impairments that require special assistance in the development, communication and training for independent living. In our environment, deaf-blind children are being educated in schools for children with visual impairments or in schools for children with hearing impairments (in accordance with the primary impairment. However, deaf-blind children cannot be trained by means of special programs for children with hearing impairment, visual impairment or other programs for students with developmental disabilities without specific attention required by such a combination of sensory impairments. Deaf-blindness must be observed as a multiple impairment that requires special work methods, especially in the field of communication, whose development is severely compromised. Communication skills in deaf-blind people can be developed by using the calendar systems. They are designed in such a manner that they can be easily attainable to children with various sensory impairments. Calendars can be used to encourage and develop communication between adult persons and a deaf-blind child.

    Diener, Ed

    2017-07-01

    The peer review and journal system have shortcomings, and both computers and the Internet have made complementary or alternative systems attractive. In this article, I recommend that we implement a new platform for open communication of psychological science on a dedicated website to complement the current review and journal system, with reader reviews of the articles and with all behavioral scientists being eligible to publish and review articles. The judged merit of articles would be based on the citations and the ratings of the work by the whole scientific community. This online journal will be quicker, more democratic, and more informative than the current system. Although the details of the system should be debated and formulated by a committee of scientists, adding this online journal to the existing publications of a society such as the Association for Psychological Science has few risks and many possible gains. An online journal deserves to be tried and assessed.

    2014-12-01

    Full Text Available Languages based on the theory of timed automata are a well established approach for modelling and analysing real-time systems, with many applications both in industrial and academic context. Model checking for timed automata has been studied extensively during the last two decades; however, even now industrial-grade model checkers are available only for few timed automata dialects (in particular Uppaal timed automata, exhibit limited scalability for systems with large discrete state space, or cannot handle parametrised systems. We explore the use of Horn constraints and off-the-shelf model checkers for analysis of networks of timed automata. The resulting analysis method is fully symbolic and applicable to systems with large or infinite discrete state space, and can be extended to include various language features, for instance Uppaal-style communication/broadcast channels and BIP-style interactions, and systems with infinite parallelism. Experiments demonstrate the feasibility of the method.

    The Superconducting Super Collider Laboratory is a complex of accelerators being built in Ellis County, Texas. The SSCL control system consists of front-end processors and their associated control points remotely distributed from the Central and Regional control rooms. Control messages passing between these locations require timely (deterministic) distribution. A prototype network consisting of point-to-point links utilizing commercial T1 (1.544 Mb/s) communication boards has been implemented. These dedicated communication links will replace networking services traditionally provided for by shared medium networks like Ethernet(IEEE 802.3) and FDDI(IEEE 802.5). A seamless migration will be achieved by using packet encapsulation based on PPP(Point-to-Point Protocol, RFC 1171). All other networking functions including routing and reliable delivery are still being handled by the usual internet services. A distributed control system that currently uses Ethernet for communication is being re-implemented using these point-to-point links. The authors report on throughput measurements, timing constraints and ease of transition of a point-to-point network

    2017-11-14

    Security is increased in quantum communication (QC) systems lacking a true single-photon laser source by encoding a transmitted optical signal with two or more decoy-states. A variable attenuator or amplitude modulator randomly imposes average photon values onto the optical signal based on data input and the predetermined decoy-states. By measuring and comparing photon distributions for a received QC signal, a single-photon transmittance is estimated. Fiber birefringence is compensated by applying polarization modulation. A transmitter can be configured to transmit in conjugate polarization bases whose states of polarization (SOPs) can be represented as equidistant points on a great circle on the Poincare sphere so that the received SOPs are mapped to equidistant points on a great circle and routed to corresponding detectors. Transmitters are implemented in quantum communication cards and can be assembled from micro-optical components, or transmitter components can be fabricated as part of a monolithic or hybrid chip-scale circuit.

  7. Novel Reduced-Feedback Wireless Communication Systems

    KAUST Repository

    Shaqfeh, Mohammad Obaidah

    2011-11-20

    Modern communication systems apply channel-aware adaptive transmission techniques and dynamic resource allocation in order to exploit the peak conditions of the fading wireless links and to enable significant performance gains. However, conveying the channel state information among the users’ mobile terminals into the access points of the network consumes a significant portion of the scarce air-link resources and depletes the battery resources of the mobile terminals rapidly. Despite its evident drawbacks, the channel information feedback cannot be eliminated in modern wireless networks because blind communication technologies cannot support the ever-increasing transmission rates and high quality of experience demands of current ubiquitous services. Developing new transmission technologies with reduced-feedback requirements is sought. Network operators will benefit from releasing the bandwidth resources reserved for the feedback communications and the clients will enjoy the extended battery life of their mobile devices. The main technical challenge is to preserve the prospected transmission rates over the network despite decreasing the channel information feedback significantly. This is a noteworthy research theme especially that there is no mature theory for feedback communication in the existing literature despite the growing number of publications about the topic in the last few years. More research efforts are needed to characterize the trade-off between the achievable rate and the required channel information and to design new reduced-feedback schemes that can be flexibly controlled based on the operator preferences. Such schemes can be then introduced into the standardization bodies for consideration in next generation broadband systems. We have recently contributed to this field and published several journal and conference papers. We are the pioneers to propose a novel reduced-feedback opportunistic scheduling scheme that combines many desired features

    2015-08-01

    Full Text Available The effect of communicating social psychology research findings on ingroup bias in a classroom setting has been investigated. Two hundred and twenty one high school students either read or did not read a brief report about three classical social psychological studies, then completed evaluation scales for the ingroup and the outgroup. Participants’ motivation was manipulated, and the messages were different as regards the congruency between the content and participants’ actual intergroup experience. Results showed that communication exerted a significant effect in reducing ingroup bias for participants in the high motivation/high congruency condition, that is, the communication effect was moderated by the individual’s level of motivation and the content of the arguments proposed in the report. Practical implications of results for education work and stereotype change, limitations of the study, as well as possible directions for future research are discussed.

    2011-12-01

    To explore the relationship between the style of doctor-patient communication and patients' educational background in a Southeast Asian teaching hospital setting using the Roter Interaction Analysis System (RIAS). We analyzed a total of 245 audio-taped consultations involving 30 internal medicine residents with 7-10 patients each in the internal medicine outpatient clinics. The patients were categorized into a group with a high and a group with a low educational level. We ranked the data into 41 RIAS utterances and RIAS-based composite categories in order of observed frequency during consultations. The residents invariantly used a paternalistic style irrespective of patients' educational background. The RIAS utterances and the composite categories show no significant relationship between communication style and patients' educational level. Doctors in a Southeast Asian country use a paternalistic communication style during consultations, regardless of patients' educational background. To approach a more partnership doctor-patient communication, culture and clinical environment concern of Southeast Asian should be further investigated. Copyright © 2011 Elsevier Ireland Ltd.

    We have recently contributed to this field and published several journal and conference papers. We are the pioneers to propose a novel reduced-feedback opportunistic scheduling scheme that combines many desired features including fairness in resources distribution across the active terminals and distributed processing at the MAC layer level. In addition our scheme operates close to the upper capacity limits of achievable transmission rates over wireless links. We have also proposed another hybrid scheme that enables adjusting the feedback load flexibly based on rates requirements. We are currently investigating other novel ideas to design reduced-feedback communication systems.

    1983-09-01

    In postindependence Africa new and more efficient strategies were required to support educational expansion. Political independence was accompanied by an increased demand for education to meet the growing labor force needs of the emerging countries in Africa. It was considered that education, as a means for human resource development, was a viable capital investment necessary to support both social and economic development, yet in many African nations, the educational systems and the traditional teaching methods inherited from colonial rule were not adequate to satisfy the increased demand for trained personnel. In response to the need for educational reforms and expansion, governments of many African countries invested heavily in the development of their education systems. During the 1970s it is estimated that Africa spent between 15-20% of the national budget on education. That high level of expenditure was justified by the increased demand for education. The educational expansion efforts also increased shortages of qualified and competent teachers, shortages of adequate equipment, and physical facilities. New strategies and resources with required to solve these increasing problems. Many African countries began to experiment with the use of mass communication technologies to support their educational reform efforts. There was generally consensus that the mass media, particularly radio and television, had certain qualities that could be exploited either to replace or improve conventional methods of teaching. By the late 1960s at least 16 African countries were using educational broadcasting of 1 form or another. International aid agencies, govermental donor agencies, and private foundations in the industrially advanced countries provided the support base for many African countries in their efforts to use radio and television for educational improvement. Most of these efforts failed to make any significant impact on educational development in Africa. Educational

    1982-01-01

    The design of a secure communication system is described. A product code, formed from two pseudorandom sequences of digital bits, is used to encipher or scramble data prior to transmission. The two pseudorandom sequences are periodically changed at intervals before they have had time to repeat. One of the two sequences is transmitted continuously with the scrambled data for synchronization. In the receiver portion of the system, the incoming signal is compared with one of two locally generated pseudorandom sequences until correspondence between the sequences is obtained. At this time, the two locally generated sequences are formed into a product code which deciphers the data from the incoming signal. Provision is made to ensure synchronization of the transmitting and receiving portions of the system.

    The CNEA 20UD tandem accelerator manufactured by National Electrostatics Corp. is predominately controlled through a hard wired console. In the past, accelerators have used mechanical control rods to control parameters inside the high voltage terminals and dead sections. The 20UD column, has relatively complex equipment within the terminal and dead sections. Because of its complexity and the length of the column (approximately 48 ft. from ground to terminal) it was concluded that a digital communication link would be required to provide the smooth, high resolution control needed for the ion-optic components and to provide a reliable system to monitor the large number of parameters. To further ensure reliability, some basic components such as foil strippers and the terminal matching quadrupole have back-up control via control rods to allow limited operation in the event of a failure of the digital system

    Modern mobile communications satellites, such as INMARSAT 3, EMS, and ARTEMIS, use advanced onboard processing to make efficient use of the available L-band spectrum. In all of these cases, high performance surface acoustic wave (SAW) devices are used. SAW filters can provide high selectivity (100-200 kHz transition widths), combined with flat amplitude and linear phase characteristics; their simple construction and radiation hardness also makes them especially suitable for space applications. An overview of the architectures used in the above systems, describing the technologies employed, and the use of bandwidth switchable SAW filtering (BSSF) is given. The tradeoffs to be considered when specifying a SAW based system are analyzed, using both theoretical and experimental data. Empirical rules for estimating SAW filter performance are given. Achievable performance is illustrated using data from the INMARSAT 3 engineering model (EM) processors.

    2016-12-01

    Full Text Available The ability to communicate, specifically the gift of hearing, is a necessity often taken for granted. A lack of sense of hearing affects the intellectual and emotional development of the human being who suffers from it. It prevents the fluid exchange of knowledge, thoughts and ideas that allow personal growth and development. This article emerges due to an interest in providing assistive technologies that can be considered to improve communication among hearing impaired and normal hearing listeners in the class-room of a higher education level in the Republic of Panama. Information has been compiled from various primary and secondary sources highlighting the communication problem facing this group of disabled people. Information about the situation of hearing impairment, laws, organizations, the reality with the higher education system, and finally, we will talk about Information and Communication Technologies (TICs that will work as technology support in order to improve communication in the classroom in higher education among normal-hearing and deaf people.

  3. Odyssey, an optimized personal communications satellite system

    Science.gov (United States)

    Rusch, Roger J.

    Personal communications places severe demands on service providers and transmission facilities. Customers are not satisfied with the current levels of service and want improvements. Among the characteristics that users seek are: lower service rates, hand held convenience, acceptable time delays, ubiquitous service, high availability, reliability, and high quality. The space industry is developing commercial space systems for providing mobile communications to personal telephones. Provision of land mobile satellite service is fundamentally different from the fixed satellite service provided by geostationary satellites. In fixed service, the earth based antennas can depend on a clear path from user to satellite. Mobile users in a terrestrial environment commonly encounter blockage due to vegetation, terrain or buildings. Consequently, high elevation angles are of premium value. TRW studied the issues and concluded that a Medium Earth Orbit constellation is the best solution for Personal Communications Satellite Service. TRW has developed Odyssey, which uses twelve satellites in medium altitude orbit to provide personal communications satellite service. The Odyssey communications system projects a multibeam antenna pattern to the Earth. The attitude control system orients the satellites to ensure constant coverage of land mass and coastal areas. Pointing can be reprogrammed by ground control to ensure optimized coverage of the desired service areas. The payload architecture features non-processing, "bent pipe" transponders and matrix amplifiers to ensure dynamic power delivery to high demand areas. Circuit capacity is 3000 circuits per satellite. Each satellite weighs 1917 kg (4226 pounds) at launch and the solar arrays provide 3126 Watts of power. Satellites are launched in pairs on Ariane, Atlas, or other vehicles. Each satellite is placed in a circular orbit at an altitude of 10,354 km. There are three orbit planes inclined at 55° to the equatorial plane

    To develop a wireless communication system to meet the stringent requirements for a nuclear hot cell and similar environments, including control of advanced servomanipulators, a microwave signal transmission system development program was established to produce a demonstration prototype for the Consolidated Fuel Reprocessing Program at Oak Ridge National Laboratory (ORNL). Proof-of-principle tests in a partially metal lined enclosure at ORNL successfully demonstrated the feasibility of directed microwave signal transmission techniques for remote systems applications. The potential for much more severe radio-frequency (RF) multipath propagation conditions in fully metal lined cells led to a programmatic decision to conduct additional testing in more typical hot-cell environments at other sites. Again, the test results were excellent. Based on the designs of the earlier systems, an advanced microwave signal transmission system configuration was subsequently developed that, in highly reflective environments, will support both high-performance video channels and high baud-rate digital data links at total gamma dose tolerance levels exceeding 10(exp 7) rads and at elevated ambient temperatures.

    In order to accommodate the increasing number of computerized subsystems aboard today's more fuel efficient aircraft, the Boeing Co. has developed the DATAC (Digital Autonomous Terminal Access Control) bus to minimize the need for point-to-point wiring to interconnect these various systems, thereby reducing total aircraft weight and maintaining an economical flight configuration. The DATAC bus is essentially a local area network providing interconnections for any of the flight management and control systems aboard the aircraft. The task of developing a Bus Monitor Unit was broken down into four subtasks: (1) providing a hardware interface between the DATAC bus and the Z8000-based microcomputer system to be used as the bus monitor; (2) establishing a communication link between the Z8000 system and a CP/M-based computer system; (3) generation of data reduction and display software to output data to the console device; and (4) development of a DATAC Terminal Simulator to facilitate testing of the hardware and software which transfer data between the DATAC's bus and the operator's console in a near real time environment. These tasks are briefly discussed.

    Document available in abstract form only. Full text of publication follows: Andra is responsible for proposing and implementing industrial management solutions for France's radioactive waste. Andra's goal is to ensure that everyone has the opportunity to make up his or her own mind on a subject that generates such heated debate within our society. This duty of communication is enshrined in law and is an integral part of Andra's activities, in the same way as research, industry and risk management. Because the subject of radioactive waste is a complex one and concerns such a variety of audiences, Andra adapts its communication policy so that it is accessible to all, according to individual needs and levels of interest. For the 'non-specialists' (general public, young people, etc.) Andra proposes a system built around education and awareness-raising. Its aim is to make the subject of radioactive waste accessible to and comprehensible to as many as possible. Its educational communication approach is built on 3 pillars: first and foremost information, the keystone of any system of communication, then explanation and finally sharing with the legitimate stakeholders in this pedagogical approach. Providing dependable information Andra offers information that is appropriate to the level of knowledge of its audiences and uses all communication media

    Effective communication is a vital component of patient-centered consultations with favorable treatment outcomes. This study aimed in testing the effectiveness of a personalized, communication training program for dermatologists in their practices. Fifteen dermatologists were offered the educational intervention NO.TE.S. (Non-Technical Skills). Depending on the dermatologists' needs, seven to nine sessions with a 60-min duration were performed, focusing on: patient-centered care, principles of Neurolinguistic Programming, a guide to the medical interview, principles of motivational interviewing and self-care. After the program's completion, participants completed anonymously an 18-item evaluation questionnaire. All 14 participants would suggest NO.TE.S to a colleague. According to the main themes identified, their participation led to (i) re-consideration of the physician-patient relationship, (ii) more conscious application of the patient-centered model, (iii) improvement in communication skills, (iv) awareness of medical interview guides, (v) increase in self-confidence, and (vi) techniques of self-care. Eleven physicians (78.6%) declared improvement in patients' satisfaction, 14 (100%) in their own satisfaction, seven (50%) in adherence to therapeutic plan and seven (50%) in treatment outcomes. The one-to-one coaching is a convenient and well-received personalized means of enhancing clinical communication in dermatologists, leading to more patient-centered medical encounters with better treatment outcomes.

    Full Text Available The article deals with the new situation in the education sector, which is characterized by the peculiarities of modern stage of the educational system’s development and by the necessity to rethink the principles of educational values in the XXI century through the prism of sustainable development’s priorities. Sociological ideas of phenomenology, which do not form social reality things or events of the material world in terms of supporters, have actively been used bu the authors and also the meaning given to these objects and events have been used in the article. Ontological and epistemological factors emergence of a new historical type of society, in our case, the information, have been disclosed from a philosophical position.  According to the authors, the state of postmodern society is primarily determined by culture. It is cultural society, which studies different external influences, including economic life, in the human world. Feature of modern social cognition that sets a new paradigm is as follows: it is carried out through the analysis of which representations had mediated self cognitive attitude to social phenomena, accompanied by the deep mentally communicative nature of social reality and brought changes in the socio-communicative sphere.

  17. Cultural selection drives the evolution of human communication systems.

    Human communication systems evolve culturally, but the evolutionary mechanisms that drive this evolution are not well understood. Against a baseline that communication variants spread in a population following neutral evolutionary dynamics (also known as drift models), we tested the role of two cultural selection models: coordination- and content-biased. We constructed a parametrized mixed probabilistic model of the spread of communicative variants in four 8-person laboratory micro-societies engaged in a simple communication game. We found that selectionist models, working in combination, explain the majority of the empirical data. The best-fitting parameter setting includes an egocentric bias and a content bias, suggesting that participants retained their own previously used communicative variants unless they encountered a superior (content-biased) variant, in which case it was adopted. This novel pattern of results suggests that (i) a theory of the cultural evolution of human communication systems must integrate selectionist models and (ii) human communication systems are functionally adaptive complex systems.

    The right to get a proper education for every citizen had been regulated by the government, but not all citizens have the same opportunity. This is due to the other factors in the nation's infrastructure, Frontier, Outermost, and Disadvantaged (3T) which have not beenaccomodatedto access information and communication technology (ICT), and the ideal learning environment in order to pursue knowledge. This condition could be achieved by reforming higher education. Such reforms include the provision of educational services in the form of a flexible learner-oriented, and to change the curriculum with market based.These changes would include the provision of lecturers, professors, and professional teaching force. Another important effort is to update the quality of higher education with resource utilization. This paper proposes a new education business model to realize the Smart Education (SE), with an orientation on the proven skills and competitive.SE is the higher education system to optimize output (outcome) learning with combine individual learning and collaboration techniques based network system, informal practice learning and formal theory. UtilizingICT resources can improve the quality and access to higher education in supporting activities of higher education.This paper shows that ICT resources can support virtual connected with the use of shared resources, such as resource of information, learning resources, computing resources, and human resources.

    2009-01-01

    Polymer Optical Fibres (POFs) show clear advantages compared to copper and glass fibres. In essence, POFs are inexpensive, space-saving and not susceptible to electromagnetic interference. Thus, the usage of POFs have become a reasonable alternative in short distance data communication. Today, POFs are applied in a wide number of applications due to these specific advantages. These applications include automotive communication systems and in-house-networks. State-of-the-art is to transmit data with only one channel over POF, this limits the bandwidth. To solve this problem, an integrated MUX/DEMUX-element for WDM over POF is designed and developed to use multiple channels. This integration leads to low costs, therefore this component is suitable for mass market applications. The fundamental idea is to separate the chromatic parts of the light in its monochromatic components by means of a grating based on an aspheric mirror. Due to the high NA of the POF the setup has to be designed in a 3D-approach. Therefore this setup cannot be compared with the planar solutions available on market, they would result high losses in the 3rd dimension. To achieve a fast and optimized design an optical simulation program is used. Particular attention has to be paid to the design of the POF as a light source in the simulation program and the optimisation of the grating. The following realization of the demultiplexer is planed to be done with injection molding. This technology offers easy and very economical processing. These advantages make this technology first choice for optical components in the low-cost array.

    Paperback books on scientific topics were a hot commodity in the United States from the 1940s to 1960s providing a vehicle for science communication that transformed science education. Well-known scientists authored them, including Rachel Carson, Theodosius Dobzhansky, George Gamow, Fred Hoyle, Julian Huxley, and Margaret Mead. A short history of 'the paperback revolution' that began in the 1930s is provided before concentrating on one publishing company based in New York City, the New American Library of World Literature (NAL), which produced Signet and Mentor Books. The infrastructure that led to the production and consumption of paperback books is described and an underexplored and not-previously identified genre of educational books on scientific topics, what the author refers to as pulp science, is characterized.

    Semali, Ladislaus M.

    1993-05-01

    Postliteracy programs have been used to produce written materials for newly literate adults, but this narrow view falls short of preventing relapse into illiteracy. Furthermore, the gradual move away from mass educational programs and government financing of education has put postliteracy at greater risk. This study tests levels of retention of literacy among neo-literates in Tanzania who gained a literacy certificate five years ago. Some modest success is noted. The pattern of radio broadcasting, newspaper coverage and library provision in the country is summarized, and the influence of these media on literacy retention assessed. Investment in them is seen as crucial to the maintenance of literacy. However, it is also suggested that the cultural context cannot be overlooked, that the importance of oral communication does not swiftly diminish and that excessive emphasis on functional postliteracy texts does not coincide with the leisure-time interests of neo-literates.

Satellite link performance for data, facsimile, video and packet switching information transmission at bit rates ranging from 6.4 kbit/s to 6.3 Mbit/s have been confirmed, using a small K-band earth station and a demand-assignment time division multiple access system. A low-capacity omni-use C-band terminal experiment has verified a telephone channel transmission performance by spread-spectrum multiple access. Single point to multipoint transmission characteristics of the 64 kbit/s data signals from the computer center were tested, using a receive-only 4 GHz earth terminal. Basic satellite link performance was confirmed under clear-sky conditions. Precise satellite orbit and attitude keeping experiments were carried out to obtain precise satellite antenna pointing accuracy for development of K-band earth stations that do not require satellite tracking equipment. Precise station keeping accuracy of 0.02 degrees was obtained.

    The ATLAS Education & Outreach project has, over the years, developed a strong reputation for supporting innovation. Animated event displays, musical CDs, 3d movies, 3-storey murals, photo books, data sonifications, multi-media art installations, pub slams, masterclasses, documentaries, pop-up books, LEGO® models, and virtual visits are among the many diverse methods being exploited to communicate to the world the goals and accomplishments of the ATLAS Experiment at CERN. This variety of creativity and innovation does not pop out of a vacuum. It requires underlying motivation by the collaboration to communicate with the public; freedom and encouragement to do so in a creative manner; and a support structure for developing, implementing and promoting these activities. The ATLAS Outreach project has built this support structure on a well-defined communication plan, high-quality content, and effective delivery platforms. Most importantly, implementation of the program has been based on the effective engagement of the participating institutes and other key partners, not only to leverage modest human resources and funding, but also to take advantage of the rich imagination and inspiration of a diverse, global human collaboration. We present our current plan, on-going activities, and a few more fun innovations for the future.

  14. Ultrasound Picture Archiving And Communication Systems

    Koestner, Ken; Hottinger, C. F.

    1982-01-01

    The ideal ultrasonic image communication and storage system must be flexible in order to optimize speed and minimize storage requirements. Various ultrasonic imaging modalities are quite different in data volume and speed requirements. Static imaging, for example B-Scanning, involves acquisition of a large amount of data that is averaged or accumulated in a desired manner. The image is then frozen in image memory before transfer and storage. Images are commonly a 512 x 512 point array, each point 6 bits deep. Transfer of such an image over a serial line at 9600 baud would require about three minutes. Faster transfer times are possible; for example, we have developed a parallel image transfer system using direct memory access (DMA) that reduces the time to 16 seconds. Data in this format requires 256K bytes for storage. Data compression can be utilized to reduce these requirements. Real-time imaging has much more stringent requirements for speed and storage. The amount of actual data per frame in real-time imaging is reduced due to physical limitations on ultrasound. For example, 100 scan lines (480 points long, 6 bits deep) can be acquired during a frame at a 30 per second rate. In order to transmit and save this data at a real-time rate requires a transfer rate of 8.6 Megabaud. A real-time archiving system would be complicated by the necessity of specialized hardware to interpolate between scan lines and perform desirable greyscale manipulation on recall. Image archiving for cardiology and radiology would require data transfer at this high rate to preserve temporal (cardiology) and spatial (radiology) information.

    2016-01-01

    Hybrid systems are dynamic systems with interacting discrete computation and continuous physical processes.

    In GPS monitoring system, wireless communications network is necessary to keep base station in contact with mobile stations. Public communications network and personal communications network can't work well all the time. In this article, an economical communications network that can be competent for communication of GPS monitoring system is introduced. Personal communications network is used in this GPS monitoring system. In order to enlarge the coverage area and to expand the capacity of the personal communications network, the concept of cellular radio system is introduced. Because only the non-adjacent cells can use the same frequency channel, handoff of mobile station is extremely important when it goes in another cell. The mobile station of the system will know its own longitude and latitude by receiving data from GPS satellites all the time, so it can change its working frequency channel according to its position. Internet, instead of personal communication cable, is used to connect the base stations. So the communications network has the advantage of public communications network and personal one.

    Optical fibre communications has proved to be one of the key application areas, which created, and ultimately propelled the global growth of the photonics industry over the last twenty years. Consequently the teaching of the principles of optical fibre communications has become integral to many university courses covering photonics technology. However to reinforce the fundamental principles and key technical issues students examine in their lecture courses and to develop their experimental skills, it is critical that the students also obtain hands-on practical experience of photonics components, instruments and systems in an associated teaching laboratory. In recognition of this need OptoSci, in collaboration with university academics, commercially developed a fibre optic communications based educational package (ED-COM). This educator kit enables students to; investigate the characteristics of the individual communications system components (sources, transmitters, fibre, receiver), examine and interpret the overall system performance limitations imposed by attenuation and dispersion, conduct system design and performance analysis. To further enhance the experimental programme examined in the fibre optic communications kit, an extension module to ED-COM has recently been introduced examining one of the most significant performance parameters of digital communications systems, the bit error rate (BER). This add-on module, BER(COM), enables students to generate, evaluate and investigate signal quality trends by examining eye patterns, and explore the bit-rate limitations imposed on communication systems by noise, attenuation and dispersion. This paper will examine the educational objectives, background theory, and typical results for these educator kits, with particular emphasis on BER(COM).

  14. Empathic Communications and Narrative Competence in Contemporary Medical Education

    Directory of Open Access Journals (Sweden)

    Lindsay Holmgren

    2016-12-01

    Full Text Available Lindsay Holmgren’s “Empathic Communications and Narrative Competence in Contemporary Medical Education” reviews the teaching of narrative competency in medical education, arguing that these practices must engage postclassical approaches to narrative studies while attending to the concept of empathy as it is deployed in various disciplines, including narratology, cognitive science, and psychology. With an emphasis on the formation of professional identity in medical practice, Holmgren explores the relationship between professional identity in a multi-ethnic, gender-neutral, demographically and culturally diverse medical education context, and the complex arena of narrative empathy. Hinging her argument on the reciprocal nature of identity that emerges at the intersections of various versions of the self and others, Holmgren’s article aligns the empathy developed by reading fiction with that which develops in the clinical encounter. Finally, the article understands these various, evolving subject positions rhetorically, arguing that the comportments of medical educators in the humanities should be such that their students will want to emulate them.

    Full Text Available Entrepreneurship has been regarded as a new science in the promotion of economic development, which has led to rapid development in entrepreneurship education. The growing number of students enrolled in entrepreneurship programs creates unprecedented challenges on educators. Although multiple teaching and learning activities are adopted in entrepreneurship education, these are mainly carried out using traditional classroom lectures, case studies and group discussions. Nowadays, information & communication technology (ICT is used to enhance the effectiveness of traditional teaching methods and competency training. PowToon is a web-based ICT tool that hat allows teachers and students to quickly and easily create animated presentations. Using quasi-experimental design and qualitative method, this study is to examine whether PowToon is an effective tool for business plan presentation. The study find that the animated presentations attracted more investment than the groups that did not prepare animated videos. It reflects that developed videos which helps entrepreneurial team to better deliver their business ideas to investors in a well-thought out way. In addition, the results of the study show that individuals who generate a business idea did not necessarily significantly influence their investment decisions. Our findings challenge the concept on self-biases evaluations of the economic potential of their own business ideas. Finally, the students were very willing to adopt new ways of delivering their business ideas.

    2009-12-01

    The College of Charleston is developing several new geoscience-based education modules for integration into the Earth System Science Education Alliance (ESSEA). These three new modules provide opportunities for science and pre-service education students to participate in inquiry-based, data-driven experiences. The three new modules will be discussed in this session. Coastal Crisis is a module that analyzes rapidly changing coastlines and uses technology - remotely sensed data and geographic information systems (GIS) to delineate, understand and monitor changes in coastal environments. The beaches near Charleston, SC are undergoing erosion and therefore are used as examples of rapidly changing coastlines. Students will use real data from NASA, NOAA and other federal agencies in the classroom to study coastal change. Through this case study, learners will acquire remotely sensed images and GIS data sets from online sources, utilize those data sets within Google Earth or other visualization programs, and understand what the data is telling them. Analyzing the data will allow learners to contemplate and make predictions on the impact associated with changing environmental conditions, within the context of a coastal setting. To Drill or Not To Drill is a multidisciplinary problem based module to increase students’ knowledge of problems associated with nonrenewable resource extraction. The controversial topic of drilling in the Arctic National Wildlife Refuge (ANWR) examines whether the economic benefit of the oil extracted from ANWR is worth the social cost of the environmental damage that such extraction may inflict. By attempting to answer this question, learners must balance the interests of preservation with the economic need for oil. The learners are exposed to the difficulties associated with a real world problem that requires trade-off between environmental trust and economic well-being. The Citizen Science module challenges students to translate scientific

    Full Text Available The breakthrough in communication technology, especially that of GSM phones, in Nigeria is one of the best things that has happened to the nation in terms of its technological advancement. In Nigeria, GSM means Telecom Explosion. The GSM revolution began in August 2001 and changed the face of Information and Communications Technology in Nigeria. It is much easier to reach anybody that you have his / her number, whether they are in the village or in their closet unless in a place where there is no network of the service provider. As revolutionary as GSM may seem to be, its negative effect on our educational sector is of great concern. The ongoing war against examination malpractice is yet to take its toll on perpetrators as they have devised a new method to continue their game through the cell phone technology. Described as e-cheating, the cell phone technology is providing students a smart way to beat the best effort of stakeholders to stamp out the menace. This paper examines GSM technology, the various ways in which cell phones are employed to cheat and suggestions on how to stop e-cheating through cell phones.

    2017-01-01

    NASA is developing thin-film based, deployable propulsion, power, and communication systems for small spacecraft that could provide a revolutionary new capability allowing small spacecraft exploration of the solar system. By leveraging recent advancements in thin films, photovoltaics, and miniaturized electronics, new mission-level capabilities will be enabled aboard lower-cost small spacecraft instead of their more expensive, traditional counterparts, enabling a new generation of frequent, inexpensive deep space missions. Specifically, thin-film technologies are allowing the development and use of solar sails for propulsion, small, lightweight photovoltaics for power, and omnidirectional antennas for communication. Like their name implies, solar sails 'sail' by reflecting sunlight from a large, lightweight reflective material that resembles the sails of 17th and 18th century ships and modern sloops. Instead of wind, the sail and the ship derive their thrust by reflecting solar photons. Solar sail technology has been discussed in the literature for quite some time, but it is only since 2010 that sails have been proven to work in space. Thin-film photovoltaics are revolutionizing the terrestrial power generation market and have been found to be suitable for medium-term use in the space environment. When mounted on the thin-film substrate, these photovoltaics can be packaged into very small volumes and used to generate significant power for small spacecraft. Finally, embedded antennas are being developed that can be adhered to thin-film substrates to provide lightweight, omnidirectional UHF and X-band coverage, increasing bandwidth or effective communication ranges for small spacecraft. Taken together, they may enable a host of new deep space destinations to be reached by a generation of spacecraft smaller and more capable than ever before.

    2010-11-01

    Full Text Available This paper presents the results of a research aimed at explaining the system of interactions of social actors in Public Communication of Science and Technology (PCST, in the context of a social web defined by the novel systems of communication sustained on informational and communication technologies. The study’s theoretical framework highlights the strategic importance of a Public Communication  which focuses on promoting public appropriation of Science and Technology, going beyond the role of Journalism and Science Communication that informs a qualified public, to one that stablishes a bond with policies and decision making in the area, made with participation of international agencies, governments, producers of science and technology, journalists’ associations, educational institutions, and citizens. The research relies on Explicative Methodology. A revision of pertinent bibliography leads to the conclusion that the system of social interactions mediated by personal, interpersonal and grupal global communications, define the relationships in the communicational exchange of the social actor with regard to public communication of science and technology and policies aimed at its appropriation.

    New services and applications are causing an exponential increase in the internet traffic. In a few years, the current fiber-optic communication system infrastructure will not be able to meet this demand because fiber nonlinearity dramatically limits the information transmission rate. Eigenvalue communication is considered an emerging paradigm in fiber-optic communications that could potentially overcome these limitations. It relies on a mathematical technique called “inverse scattering trans...

  13. Parallel communicating grammar systems with context-free components are Turing complete for any communication model

    Directory of Open Access Journals (Sweden)

    Wilkin Mary Sarah Ruth

    2016-12-01

    Full Text Available Parallel Communicating Grammar Systems (PCGS were introduced as a language-theoretic treatment of concurrent systems. A PCGS extends the concept of a grammar to a structure that consists of several grammars working in parallel, communicating with each other, and so contributing to the generation of strings. PCGS are usually more powerful than a single grammar of the same type; PCGS with context-free components (CF-PCGS in particular were shown to be Turing complete. However, this result only holds when a specific type of communication (which we call broadcast communication, as opposed to one-step communication is used. We expand the original construction that showed Turing completeness so that broadcast communication is eliminated at the expense of introducing a significant number of additional, helper component grammars. We thus show that CF-PCGS with one-step communication are also Turing complete. We introduce in the process several techniques that may be usable in other constructions and may be capable of removing broadcast communication in general.

  15. Technical comparison of several global mobile satellite communications systems

    Science.gov (United States)

    Comparetto, Gary M.

    The era of satellite-based mobile satellite communications (MSC) systems started with the first MARISAT satellite which was launched into a geostationary orbit over the Pacific Ocean in 1976 to provide communications between ships and shore stations. The combination of high cost and unacceptably large equipment has kept the space-based MSC systems from appealing to the wider market of personal mobile communications. The progress made over the last ten years, however, in digital voice processing, satellite technology, and component miniaturization has resulted in the viability of satellite-based mobile satellite communications systems to meet the growing market in personal mobile communications using handsets similar to those currently in use with land-based cellular systems. Three of the more mature LEO/MEO satellite systems are addressed in this paper including GLOBALSTAR, Iridium, and Odyssey. The system architectures of each system are presented along with a description of the satellite and user handset designs and the multiaccess techniques employed. It will be shown that, although a number of similarities exist among the system addressed, each system is unique in a variety of significant design areas. It is concluded that the technical feasibility of satellite-based mobile satellite communications systems seems to be secure. It will be challenging, however, for the vendors to actually develop and deploy these systems in a cost effective, timely, and reliable way that meets a continually evolving set of requirements based upon a rapidly changing technology base.

  16. THE MOVEMENT SYSTEM IN EDUCATION.

    Hoogenboom, Barbara J; Sulavik, Mark

    2017-11-01

    Although many physical therapists have begun to focus on movement and function in clinical practice, a significant number continue to focus on impairments or pathoanatomic models to direct interventions. This paradigm may be driven by the current models used to direct and guide curricula used for physical therapist education. The methods by which students are educated may contribute to a focus on independent systems, rather than viewing the body as a functional whole. Students who enter practice must be able to integrate information across multiple systems that affect a patient or client's movement and function. Such integration must be taught to students and it is the responsibility of those in physical therapist education to embrace and teach the next generation of students this identifying professional paradigm of the movement system. The purpose of this clinical commentary is to describe the current state of the movement system in physical therapy education, suggest strategies for enhancing movement system focus in entry level education, and envision the future of physical therapy education related to the movement system. Contributions by a student author offer depth and perspective to the ideas and suggestions presented. 5.

    2011-03-01

    Gender is increasingly regarded as an important factor in doctor-patient communication education. This review aims to assess if and how gender is addressed by current assessment instruments for communication skills in medical education. In 2009 at Radboud University Nijmegen Medical Centre, an online search was conducted in the bibliographic databases PubMed, PsycINFO and ERIC for references about communication skills assessment instruments designed to be completed by trained faculty staff and used in medical education. The search strategy used the following search terms: 'consultation skills'; 'doctor-patient communication'; 'physician-patient relations'; 'medical education'; 'instruments'; 'measurement', and 'assessment'. Papers published between January 1999 and June 2009 were included. The assessment instruments identified were analysed for gender-specific content. The search yielded 21 communication skills assessment instruments. Only two of the 17 checklists obtained explicitly considered gender as a communication-related issue. Only six of 21 manuals considered gender in any way and none gave specific details to explain which aspects of communication behaviour should be assessed with regard to gender. Very few communication assessment instruments in medical education focus on gender. Nevertheless, interest exists in using gender in communication skills assessment. The criteria for and purpose of assessing gender in communication skills in medical education are yet to be clarified. © Blackwell Publishing Ltd 2011.

  19. Reducing OR Traffic Using Education, Policy Development, and Communication Technology.

    2016-01-01

    A bundled approach to surgical site infection (SSI) prevention strategies includes reducing OR traffic. A nurse-led quality improvement (QI) team sought to reduce OR traffic through education and a process change that included wireless communication technology and policy development. The team measured OR traffic by counting the frequency of door openings per hour in seven surgical suites during 305 surgical procedures conducted during similar 22-week periods before and after the QI project intervention. Door openings decreased significantly (P < 0.05) from an average of 37.8 per hour to 32.8 per hour after the QI project intervention. This suggests that our multifaceted approach reduces OR traffic. The next steps of this project include analyzing automatically captured video to understand OR traffic patterns and expanding education to departments and external personnel frequently present in our surgical suites. Future research evaluating the effectiveness of this OR traffic initiative on SSI incidence is recommended. Copyright © 2016 AORN, Inc. Published by Elsevier Inc. All rights reserved.

  4. Chaotic Secure Communication Systems with an Adaptive State Observer

    Directory of Open Access Journals (Sweden)

    Wei-Der Chang

    2015-01-01

    Full Text Available This paper develops a new digital communication scheme based on using a unified chaotic system and an adaptive state observer. The proposed communication system basically consists of five important elements: signal modulation, chaotic encryption, adaptive state observer, chaotic decryption, and signal demodulation. A sequence of digital signals will be delivered from the transmitter to the receiver through a public channel. It is rather reasonable that if the number of signals delivered on the public channel is fewer, then the security of such communication system is more guaranteed. Therefore, in order to achieve this purpose, a state observer will be designed and its function is to estimate full system states only by using the system output signals. In this way, the signals delivered on the public channel can be reduced mostly. According to these estimated state signals, the original digital sequences are then retrieved completely. Finally, experiment results are provided to verify the applicability of the proposed communication system.

    Effective communication between nurses and patients with dementia promotes the quality of patient care by improving the identification of patient needs and by reducing the miscommunication-related frustration of patients and nurses. This study evaluates the effects of an advanced innovative Internet-based communication education (AIICE) program on nurses' communication knowledge, attitudes, frequency of assessing patient communication capacity, and communication performance in the context of care for patients with dementia. In addition, this study attempts to evaluate the indirect effects of this program on outcomes for patients with dementia, including memory and behavior-related problems and depressive symptoms. A quasi-experimental research design with a one-group repeated measure was conducted. Convenience sampling was used to recruit nurses from long-term care facilities in southern Taiwan. Data were analyzed using general estimating equations to compare changes over time across three points: baseline, fourth-week posttest, and 16th-week posttest. One hundred five nurses completed the AIICE program and the posttest surveys. The findings indicate that nurses' communication knowledge, frequency in assessing patients' communication capacity, and communication performance had improved significantly over the baseline by either the 4th- or 16th-week posttest (p < .01). However, communication attitude showed no significant improvement in the posttest survey (p = .40). Furthermore, the findings indicate that the memory and behavior-related problems and the depressive symptoms of patients had decreased significantly by the 16th-week posttest (p = .05). This study showed that the AIICE program improves nurses' communication knowledge, frequency to assess patients' communication capacity, and communication performance and alleviates the memory and behavior-related problems and depressive symptoms of patients. The continuous communication training of nurses using the

  19. Communication-based positioning systems: past, present and prospects

    International Nuclear Information System (INIS)

    Ma Guanyi; Wan Qingtao; Gan Tong

    2012-01-01

    This paper reviews positioning systems in the context of communication systems. First, the basic positioning technique is described for location based service (LBS) in mobile communication systems. Then the high integrity global positioning system (iGPS) is introduced in terms of aspects of what it is and how the low Earth orbit (LEO) Iridium telecommunication satellites enhance the global positioning system (GPS). Emphasis is on the Chinese Area Positioning System (CAPS) which is mainly based on commercial geostationary (GEO) communication satellites, including decommissioned GEO and inclined geosynchronous communication satellites. Characterized by its low cost, high flexibility, wide-area coverage and ample frequency resources, a distinctive feature of CAPS is that its navigation messages are generated on the ground, then uploaded to and forwarded by the communication satellites. Fundamental principles and key technologies applied in the construction of CAPS are presented in detail from the CAPS validation phase to its experimental system setup. A prospective view of CAPS has concluded it to be a seamless, high accuracy, large capacity navigation and communication system which can be achieved by expanding it world wide and enhancing it with LEO satellites and mobile base stations. Hence, this system is a potential candidate for the next generation of radio navigation after GPS. (invited reviews)

  20. Disability and the education system.

    Science.gov (United States)

    Aron, Laudan; Loprest, Pamela

    2012-01-01

    Education is important for all children, but even more so for children with disabilities, whose social and economic opportunities may be limited. In this article, Laudan Aron and Pamela Loprest assess how well the nation's education system is serving students with disabilities. Aron and Loprest trace the evolution of the special education system in the United States from its origins in the civil rights movement of the mid-twentieth century. They note the dual character of federal legislation, which both guarantees eligible children with disabilities the right to a "free, appropriate public education in the least restrictive setting" and establishes a federal funding program to help meet this goal. They then review the types of services and accommodations these children receive from infancy through young adulthood. The special education system has given children with disabilities much greater access to public education, established an infrastructure for educating them, helped with the earlier identification of disabilities, and promoted greater inclusion of these children alongside their nondisabled peers. Despite these advances, many problems remain, including the over- and underidentification of certain subgroups of students, delays in identifying and serving students, and bureaucratic, regulatory, and financial barriers that complicate the program for everyone involved. More important, the authors show that special education students still lag behind their nondisabled peers in educational achievements, are often held to lower expectations, are less likely to take the full academic curriculum in high school, and are more likely to drop out of school. Only limited evidence is available on the effectiveness of specific special education services or on how to improve student achievement for this important subgroup of students. Improving the system will require better ways of understanding and measuring both ends of the special education continuum, namely, what

    2010-07-01

    Communication skills deficits and stereotyped behaviors are frequently found among people with pervasive developmental disabilities like autism. These communication and behavioral oddities of autism are often considered to be difficult to treat and are challenging. Picture exchange communication system (PECS) is a six-phase picture system based on applied behavior analysis and is specially designed to overcome these communication difficulties in children with autism by encouraging the child to be the communication initiator. The present paper throws light on the process of using PECS along with other traditional behavioral approaches in managing communication deficits and behavioral stereotypies in a seven-year-old male child diagnosed as having childhood autism. The identified target behaviors of repeated head turning, flapping his hands, poor communication skills were assessed using various rating scales including visual analogue scale as per clinician observation and parental reports and managed using PECS as an adjunct to traditional behavioral techniques of contingency management, differential reinforcement, task direction and reprimand. Outcome was assessed using same tools after thirty-two sessions of interventions spread over three months. Significant improvements of around 60% were observed in the target behaviors.

  5. Engineering Ethics Education on the Basis of Continuous Education to Improve Communication Ability

    Science.gov (United States)

    Takahara, Kenji; Kajiwara, Toshinori

    The paper proposes the engineering ethics education method for students on the basis of continuous education to improve communication ability. First, through a debate, the students acquire the fundamental skills required to marshal their arguments, to construct the rebuttals and to summarize the debates. Secondly, the students study the fundamental techniques to make a presentation on technical subjects related to electrical engineering. Following these classes, in the lecture of engineering ethics, the students probe the cause of each accident and consider the better means for avoiding such an accident, each other. In most cases, the students can express right and commonsensical opinions from an ethical standpoint. However, they can hardly make judgments when the situations such as the human relations in the above accidents are set concretely. During the engineering ethics class, the students come to know that human relations behind the case make the ethical matters more complicated. Furthermore, they come to understand that facilitating daily communications with co-workers and/or bosses is very important in order to avoid the accidents. The recognition of the students is just the results of the continuous education through three years. It can be said that the engineering ethics education thus constructed makes the students raise such spontaneous awareness and their ethical qualities as engineers.

    Today's CubeSats mostly operate their communications at UHF- and S-band frequencies. UHF band is presently crowded, thus downlink communications are at lower data rates due to bandwidth limitations and are unreliable due to interference. This research presents an end-to-end robust, innovative, compact, efficient and low cost S-band uplink and X-band downlink CubeSat communication system demonstration between a balloon and a Near Earth Network (NEN) ground system. Since communication systems serve as umbilical cords for space missions, demonstration of this X-band communication system is critical for successfully supporting current and future CubeSat communication needs. This research has three main objectives. The first objective is to design, simulate, and test a CubeSat S- and X-band communication system. Satellite Tool Kit (STK) dynamic link budget calculations and HFSS Simulations and modeling results have been used to trade the merit of various designs for small satellite applications. S- and X-band antennas have been tested in the compact antenna test range at Goddard Space Flight Center (GSFC) to gather radiation pattern data. The second objective is simulate and test a CubeSat compatible X-band communication system at 12.5Mbps including S-band antennas, X-band antennas, Laboratory for Atmospheric and Space Physics (LASP) /GSFC transmitter and an S-band receiver from TRL-5 to TRL-8 by the end of this effort. Different X-band communication system components (antennas, diplexers, etc.) from GSFC, other NASA centers, universities, and private companies have been investigated and traded, and a complete component list for the communication system baseline has been developed by performing analytical and numerical analysis. This objective also includes running simulations and performing trades between different X-band antenna systems to optimize communication system performance. The final objective is to perform an end-to-end X-band CubeSat communication system

    CERN Document Server

    Locci, F

    2014-01-01

    In CERN accelerators control system several components are essential such as: Programmable Logic Controller (PLC), PCI Extensions for Instrumentation (PXI), and other micro-controller families. Together with their weaknesses and their strength points they typically present custom communication protocols and it is therefore difficult to federate them into the control system using a single communication strategy. Furthermore this dependency to the physical device interfaces and protocols makes most of the code not reusable and the replacement of old technology a difficult problem. The purpose of IEPLC ([1]) is to mitigate the communication issues given by this heterogeneity; it proposes a framework to define communication interfaces in a hardware independent manner. In addition it automatically generates all the resources needed on master side (typically represented by a FEC: Front-End Computer) and slave side (typically represented by the controller) to implement a common and generic Ethernet communication.

  6. PACS/information systems interoperability using Enterprise Communication Framework.

    Science.gov (United States)

    alSafadi, Y; Lord, W P; Mankovich, N J

    1998-06-01

    Interoperability among healthcare applications goes beyond connectivity to allow components to exchange structured information and work together in a predictable, coordinated fashion. To facilitate building an interoperability infrastructure, an Enterprise Communication Framework (ECF) was developed by the members of the Andover Working Group for Healthcare Interoperability (AWG-OHI). The ECF consists of four models: 1) Use Case Model, 2) Domain Information Model (DIM), 3) Interaction Model, and 4) Message Model. To realize this framework, a software component called the Enterprise Communicator (EC) is used. In this paper, we will demonstrate the use of the framework in interoperating a picture archiving and communication system (PACS) with a radiology information system (RIS).

  9. CHALLENGES IN DEVELOPING A MANAGEMENT AND COMMUNICATION PLATFORM INSIDE A HIGHER EDUCATIONAL ORGANIZATION

    Directory of Open Access Journals (Sweden)

    MUSCALU EMANOIL

    2015-04-01

    Full Text Available At present, the world is in a phase of economic and social development, with many and varied features of the knowledge society based on science and education. The organization is defined not only by the products and / or services, but also the ability to communicate to its employees and management team. Continuous exchange of messages is the correlation factor that generates knowledge in the society and inside the organization to fulfill its mission and strategies. The purpose of this work is to identify the necessity of developing a platform which should provide the support for the organization and also for the specific activities developed inside the organization. Also, when developing such a system, there are few aspects that should be taken into consideration, according to the organization’s goals. Therefore the development of a platform by a higher educational institution could improve the communication inside the organization, could improve the management’s activity and also can provide access to knowledge for the students. Developing a judicial platform, for students, could provide possible solutions to problems like training and practice, or other problems emphasized by the law experts that recorded for example unreasonable deadlines given by the courts in insolvency and commercial cases in general, by improving internal and external communication and improving the quality of commercial law and not only.

    Chi, Liping

    2013-04-01

    Although the intergenerational transmission of educational attainment has been confirmed by many researchers, its mechanism still remains controversial. Parent-child communication has been regarded as one of the important mediators. The present study primarily aimed to examine the potentially mediating role of parent-child communication in the transmission of educational attainment, based on a sample of 366 Chinese fifth and sixth graders. Parent-child communication was measured against the three levels of the parents' communication ability, the quality of the father-child and mother-child communications, and the relation between the two dyadic communications. The results duplicated the positive effect of parents' educational attainment on children's academic achievement. Moreover, it was found that parents' communication ability alone played a mediating role, and that the three levels of parent-child communication constructed a "mediator chain" between the parents' educational attainment and the children's academic achievement. Finally, the intergenerational transmission of educational attainment in China and the mediating role of the three levels of parent-child communication were discussed. © 2012 The Institute of Psychology, Chinese Academy of Sciences and Blackwell Publishing Asia Pty Ltd.

    The rapid economic growth of Japan since World War II has resulted in Japan becoming a reference point for developing nations and the West. This remarkable growth results from a combination of factors, one of which has been unyielding attention to education in order to cultivate the human talent necessary to provide the productivity for economic growth. The Japanese education system emphasizes quality of instruction and rewards hard work. Some of the principles of the system are outlined together with a summary of the content of the curriculum, the quantity and quality of instruction, and the influence of culture and environment.

  19. Social-communicative effects of the Picture Exchange Communication System (PECS) in autism spectrum disorders.

    2012-01-01

    The Picture Exchange Communication System (PECS) is a common treatment choice for non-verbal children with autism. However, little empirical evidence is available on the usefulness of PECS in treating social-communication impairments in autism. To test the effects of PECS on social-communicative skills in children with autism, concurrently taking into account standardized psychometric data, standardized functional assessment of adaptive behaviour, and information on social-communicative variables coded in an unstructured setting. Eighteen preschool children (mean age = 38.78 months) were assigned to two intervention approaches, i.e. PECS and Conventional Language Therapy (CLT). Both PECS (Phases I-IV) and CLT were delivered three times per week, in 30-min sessions, for 6 months. Outcome measures were the following: Autism Diagnostic Observation Schedule (ADOS) domain scores for Communication and Reciprocal Social Interaction; Language and Personal-Social subscales of the Griffiths' Mental Developmental Scales (GMDS); Communication and Social Abilities domains of the Vineland Adaptive Behavior Scales (VABS); and several social-communicative variables coded in an unstructured setting. Results demonstrated that the two groups did not differ at Time 1 (pre-treatment assessment), whereas at Time 2 (post-test) the PECS group showed a significant improvement with respect to the CLT group on the VABS social domain score and on almost all the social-communicative abilities coded in the unstructured setting (i.e. joint attention, request, initiation, cooperative play, but not eye contact). These findings showed that PECS intervention (Phases I-IV) can improve social-communicative skills in children with autism. This improvement is especially evident in standardized measures of adaptive behaviour and measures derived from the observation of children in an unstructured setting. © 2012 Royal College of Speech and Language Therapists.

    The particular Ku-band carrier, PN despreading, and symbol synchronization strategies, which were selected for implementation in the Ku-band transponder aboard the orbiter, were assessed and evaluated from a systems performance viewpoint, verifying that system specifications were met. A study was performed of the design and implementation of tracking techniques which are suitable for incorporation into the Orbiter Ku-band communication system. Emphasis was placed on maximizing tracking accuracy and communication system flexibility while minimizing cost, weight, and system complexity of Orbiter and ground systems hardware. The payload communication study assessed the design and performance of the forward link and return link bent-pipe relay modes for attached and detached payloads. As part of this study, a design for a forward link bent-pipe was proposed which employs a residual carrier but which is tracked by the existing Costas loop.

    1980-01-01

    There is a considerable interest in seismology from the nonprofessional or amateur standpoint. The operation of a seismic system can be satisfying and educational, especially when you have built and operated the system yourself. A long-period indoor-type sensor and recording system that works extremely well has been developed in the James Madison University Physics Deparment. The system can be built quite economically, and any educational institution that cannot commit themselves to a professional installation need not be without first-hand seismic information. The system design approach has been selected by college students working a project or senior thesis, several elementary and secondary science teachers, as well as the more ambitious tinkerer or hobbyist at home

  5. Perspective: clinical communication education in the United Kingdom: some fresh insights.

    Science.gov (United States)

    Brown, Jo

    2012-08-01

    Clinical communication education is now part of the core curriculum of every medical school in the United Kingdom and the United States. It has emerged over 30 years because of various societal, political, and policy drivers and is supported by an impressive evidence base.For a variety of reasons, however, clinical communication has become separated from other parts of medical education and tends to be positioned in the early years of the curriculum, when students have limited experience of being in the clinical workplace and working with patients. The teachers of clinical communication, whether medical-school-based or clinically based, may not share learning goals for the subject and this may, therefore, provide a disintegrated learning experience for students.Clinical communication teachers need to inject fresh thinking into the teaching and learning of the subject to unite it with clinical practice in the authentic clinical workplace. Engaging with theories of workplace learning, which aim to overcome the theory/practice gap in vocational education, may be the way forward. The author suggests various ways that this might be achieved-for example, by situating clinical communication education throughout the whole undergraduate curriculum, by integrating the topic of clinical communication with other areas of medical education, by developing coteaching and curriculum design partnerships between medical school and clinical workplace, and by developing a greater range of postgraduate education that offers opportunities for professional development in clinical communication for qualified doctors that is complementary with what is taught in undergraduate education.

  8. Impact of a bone conduction communication channel on multichannel communication system effectiveness.

    Blue, Misty; McBride, Maranda; Weatherless, Rachel; Letowski, Tomasz

    2013-04-01

    In this study, the impact of including a bone conduction transducer in a three-channel spatialized communication system was investigated. Several military and security forces situations require concurrent listening to three or more radio channels. In such radio systems, spatial separation between three concurrent radio channels can be achieved by delivering separate signals to the left and right earphone independently and both earphones simultaneously. This method appears to be effective; however, the use of bone conduction as one channel may provide both operational and performance benefits. Three three-channel communication systems were used to collect speech intelligibility data from 18 listeners (System I, three loudspeakers; System 2, stereo headphones; System 3, stereo headphones and a bone conduction vibrator). Each channel presented signals perceived to originate from separate locations. Volunteers listened to three sets of competing sentences and identified a number, color, and object spoken in the target sentence. Each listener participated in three trials (one per system). Each trial consisted of 48 competing sentence sets. Systems 2 and 3 were more intelligible than System I. Systems 2 and 3 were overall equally intelligible; however, the intelligibility of all three channels was significantly more balanced in System 3. Replacing an air conduction transducer with a bone conduction transducer in a multichannel audio device can provide a more effective and balanced simultaneous monitoring auditory environment. These results have important design and implementation implications for spatial auditory communication equipment.

  9. ISSUES AND RECENT TRENDS IN VEHICLE SAFETY COMMUNICATION SYSTEMS

    Directory of Open Access Journals (Sweden)

    Sadayuki TSUGAWA

    2005-01-01

    Full Text Available This paper surveys the research on the applications of inter-vehicle communications, the issues of the deployment and technology, and the current status of inter-vehicle communications projects in Europe, the United States and Japan. The inter-vehicle communications, defined here as communications between on-board ITS computers, improve road traffic safety and efficiency by expanding the horizon of the drivers and on-board sensors. One of the earliest studies on inter-vehicle communications began in Japan in the early 1980s. The inter-vehicle communications play an essential role in automated platooning and cooperative driving systems developed since the 1990's by enabling vehicles to obtain data that would be difficult or impossible to measure with on-board sensors. During these years, interest in applications for inter-vehicle communications increased in the EU, the US and Japan, resulting in many national vehicle safety communications projects such as CarTALK2000 in the EU and VSCC in the US. The technological issues include protocol and communications media. Experiments employ various kinds of protocols and typically use infrared, microwave or millimeter wave media. The situation is ready for standardization. The deployment strategy is another issue. To be feasible, deployment should begin with multiple rather than single services that would work even at a low penetration rate of the communication equipment. In addition, non-technological, legal and institutional issues remained unsolved. Although inter-vehicle communications involve many issues, such applications should be promoted because they will lead to safer and more efficient automobile traffic.

  10. Communication and the electronic health record training: a comparison of three healthcare systems.

    Lynott, Michelle H; Kooienga, Sarah A; Stewart, Valerie T

    2012-01-01

    The electronic health record (EHR) used in the examination room, is becoming the primary method of medical data storage in primary care practice in the USA. One of the challenges in using EHRs is maintaining effective patient-provider communication. Many studies have focused on communication in the examination room. Scant research exists on the best methods in educating nurse practitioners and other primary care providers (clinicians). The purpose of this study was to explore various health record training programmes for clinicians. One researcher participated in and observed three health systems' EHR training programmes for ambulatory care providers in the Pacific Northwest. A focused ethnographic approach was used, emphasising patient-provider communication. Only one system had formalised communication training in their class, the other two systems emphasised only the software and data aspects of the EHR. The fact that clinicians are expected to use EHRs in the examination room necessitates the inclusion of communication training in EHR training programmes and/or as a part of primary care nurse practitioner education programmes.

    The organisation of the Open Days at the end of September was the single biggest effort of the CMS Communications Group this year. We would like to thank all volunteers for their hard work to show our Point 5 facilities and explain science and technology to the general public. During two days more than 5,000 people visited the CMS detector underground and profited from the surface activities, which included an exhibition on CMS, a workshop on superconductivity, and an activity for our younger visitors involving wooden Kapla blocks. The Communications Group took advantage of the preparations to produce new CMS posters that can be reused at other venues. Event display images have been produced not just for this occasion but also for other exhibits, education purposes, publications etc. During the Open Days, Gilles Jobin, 2012 winner of CERN Collide@CERN prize, performed his Quantum show in Point 5, with the light installation of German artist Julius von Bismarck.

    Full Text Available A MES (Manufacturing Execution System is a system that large companies use to measure or control critical production activities. Individual parts of this system can be used as a model for development of tools suitable for small and medium enterprises (SMEs. It can demonstrate how manufacturing systems works and which communication standards are usable. The communication standards enable data acquisition, data processing, storing and their conversion for any production report. Furthermore, interfaces for web clients allow displaying the raw or transformed data as a text or a graphic chart. The development of tools for an access to the data retrieved from MES software is described in this paper.

    Real-time control applications will benefit in the near future from the enhanced performance provided by multi-core processor architectures. Nevertheless real-time communication will continue to be critical in distributed plasma control systems where the plant under control typically is distributed over a wide area. At RFX-mod real-time communication is crucial for hard real-time plasma control, due to the distributed architecture of the system, which consists of several VMEbus stations. The system runs under VxWorks and uses Gigabit Ethernet for sub-millisecond real-time communication. To optimize communication in the system, a set of detailed measurements has been carried out on the target platforms (Motorola MVME5100 and MVME5500) using either the VxWorks User Datagram Protocol (UDP) stack or raw communication based on the data link layer. Measurements have been carried out also under Linux, using its UDP stack or, in alternative, RTnet, an open source hard real-time network protocol stack. RTnet runs under Xenomai or RTAI, two popular real-time extensions based on the Linux kernel. The paper reports on the measurements carried out and compares the results, showing that the performance obtained by using open source code is suitable for sub-millisecond real-time communication in plasma control.
