The common power supplies have the disadvantages of circuit complexity and bulkiness. A novel control system of higholtage accelerating stabilized power supply for EBW was designed. Its main circuit is based on pulse-width modulation (PWM) buckboost converter topology. Compared with common EBW power supplies, this new power supply requires a much lower voltage grade transformer because of the converter's effect for rising voltage, so its volume is smaller and the circuit is simpler. The sys- tem main circuit characteristics and its working process were analyzed. The system circuit's small-signal mathematical model was created, and lag-lead correction compensation control was em- ployed in the system to achieve static and dynamic performance requirements. The results displayed that this unit had the characteristics of fast response, high reliability, high control precision and anti-interference capability.

    Schaum, Kathleen D

    2015-01-01

    Wound care professionals should consider all this attention to the key word documentation as your 2015 "heads-up." You should conduct a self-audit and request an external audit of your own documentation against all the regulations, LCDs, Policy Articles, newsletters, and educational programs that CMS and your MACs are providing. You should also embrace the questioning and assistance, pertaining to your documentation, which you may receive from your coders and billers. These coding and billing professionals should be your "best friends" to help you improve your clinical documentation as soon as possible. You cannot afford to be one of the professionals who are requested to repay for services you actually provided just because you did not take the time to document your excellent wound care work.

  18. Attitude and key word signing usage in support staff.

    Support staff may diverge in their use of augmentative and alternative communication (AAC) and key word signing (KWS). AAC use is determined by multiple personal and environmental factors. In this study, the relation between KWS attitudes and usage was examined in support staff. Twelve adults with an intellectual disability who use KWS were each filmed during a dyadic interaction with two professionals from their service: one had received first-hand (1HT) and the other second-hand KWS training (2HT). Each communication partner participated with only one client. The professionals' sign usage was coded, and their attitude towards KWS was measured using a survey and single-category Implicit Association Test (IAT). 1HT produced more signed utterances and distinct signs than 2HT, and this increase had a positive, linear relation to IAT scores. Explicit attitude did not correlate with KWS usage, but did significantly correlate with the discrepancy between intention and KWS usage. The train-the-trainer system may not reach its full potential as 2HT knew fewer distinct signs and consequently produced fewer signed utterances than 1HT. In contrast to implicit attitude, no relation was found between explicit attitude and KWS usage. Though the survey may provide valuable information, it may not fully capture the complex influences that shape AAC usage. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The word control key is one of the applications of talker recognition. Chinese differs from English or Japanese, and the four Chinese tones are important characteristics,In this paper, the four Chinese tones are analysed and nine parameters are introduced. They are (1) the pitch period (2) the two parameters of the time length of talker pronounciation, (3) the pitch pattern gradinet (in 5 sections) and (4) the sum of spectral distances. Many Chinese words consist of one syllable, lt's combinationrules consist of single vowels, diphthongs or trinphtiogs.The spectrum of the vowel uses FFT in the medium frame.This method uses a group of input signals that consists of three input signal, and decides the logic “pass” or “out” .The experimental recognition ratio is over 90% for the reference talker, 7.2% for the other talker with the reference input word,and 0% for the other talker with random input words.

    Full Text Available Abstract: The present study was conducted to investigate the effects of teaching within-text key word synonyms, opposites and related words on students’ performance on reading comprehension of TOEFL among Iranian EFL learners. To carry out the research, 60 Iranian EFL learners, who participated in a TOEFL preparation course, were selected as the participants of the study. Afterward they were randomly assigned into experimental and comparison groups. The experimental group was given a treatment including within-text key word synonyms, opposites and their translations, while the comparison group was given a placebo. To collect the required data, two instruments (a pre-test, and a post-test were administered to both groups during the experimentation. Subsequently, students’ scores were collected through the administration of different tests and the results were statistically analyzed. The results of these analyses revealed that the experimental group outperformed the comparison group and thus, it was concluded that teaching within-text key word synonyms, opposites and related words can improve the reading comprehension ability and general proficiency of EFL language learners.

    2007-01-01

    DNA cryptography is a new field which has emerged with progress in the research of DNA computing. In our study, a symmetric-key cryptosystem was designed by applying a modern DNA biotechnology, microarray, into cryptographic technologies. This is referred to as DNA symmetric-key cryptosystem (DNASC). In DNASC,both encryption and decryption keys are formed by DNA probes, while its ciphertext is embedded in a specially designed DNA chip (microarray). The security of this system is mainly rooted in difficult biology processes and problems, rather than conventional computing technology, thus it is unaffected by changes from the attack of the coming quantum computer. The encryption process is a fabrication of a specially designed DNA chip and the decryption process is the DNA hybridization.In DNASC, billions of DNA probes are hybridized and identified at the same time,thus the decryption process is conducted in a massive, parallel way. The great potential in vast parallelism computation and the extraordinary information density of DNA are displayed in DNASC to some degree.

    The aim of this study was to examine the effect of Key Word Sign (KWS) intervention on the acquisition and generalization of manual signing among three children with Autism Spectrum Disorder (ASD), and to measure any changes in their production of spoken words and gestures following intervention. A multiple baseline single-case experimental design was used to measure changes for each of the three children. All three children began using signs following the introduction of the KWS intervention, and generalized their use of some signs across activities. The introduction of the intervention was associated with either neutral, or statistically significantly positive, changes in the children's production of spoken words and natural gestures. The results provide preliminary evidence for the effectiveness of KWS for preschool children with ASD, which parents, therapists, and educators can use to inform clinical practice.

  13. Key word placing in Web page body text to increase visibility to search engines

    Directory of Open Access Journals (Sweden)

    W. T. Kritzinger

    2007-11-01

    Full Text Available The growth of the World Wide Web has spawned a wide variety of new information sources, which has also left users with the daunting task of determining which sources are valid. Many users rely on the Web as an information source because of the low cost of information retrieval. It is also claimed that the Web has evolved into a powerful business tool. Examples include highly popular business services such as Amazon.com and Kalahari.net. It is estimated that around 80% of users utilize search engines to locate information on the Internet. This, by implication, places emphasis on the underlying importance of Web pages being listed on search engines indices. Empirical evidence that the placement of key words in certain areas of the body text will have an influence on the Web sites' visibility to search engines could not be found in the literature. The result of two experiments indicated that key words should be concentrated towards the top, and diluted towards the bottom of a Web page to increase visibility. However, care should be taken in terms of key word density, to prevent search engine algorithms from raising the spam alarm.

    With the development of multi-core processors, virtualization, distributed storage, broadband Internet and automatic management, a new type of computing mode named cloud computing is produced. It distributes computation task on the resource pool which consists of massive computers, so the application systems can obtain the computing power, the storage space and software service according to its demand. It can concentrate all the computing resources and manage them automatically by the software without intervene. This makes application offers not to annoy for tedious details and more absorbed in his business. It will be advantageous to innovation and reduce cost. It's the ultimate goal of cloud computing to provide calculation, services and applications as a public facility for the public, So that people can use the computer resources just like using water, electricity, gas and telephone. Currently, the understanding of cloud computing is developing and changing constantly, cloud computing still has no unanimous definition. This paper describes three main service forms of cloud computing: SAAS, PAAS, IAAS, compared the definition of cloud computing which is given by Google, Amazon, IBM and other companies, summarized the basic characteristics of cloud computing, and emphasized on the key technologies such as data storage, data management, virtualization and programming model.

  15. Assessing language skills in adult key word signers with intellectual disabilities: Insights from sign linguistics.

    Science.gov (United States)

    Grove, Nicola; Woll, Bencie

    2017-03-01

    Manual signing is one of the most widely used approaches to support the communication and language skills of children and adults who have intellectual or developmental disabilities, and problems with communication in spoken language. A recent series of papers reporting findings from this population raises critical issues for professionals in the assessment of multimodal language skills of key word signers. Approaches to assessment will differ depending on whether key word signing (KWS) is viewed as discrete from, or related to, natural sign languages. Two available assessments from these different perspectives are compared. Procedures appropriate to the assessment of sign language production are recommended as a valuable addition to the clinician's toolkit. Sign and speech need to be viewed as multimodal, complementary communicative endeavours, rather than as polarities. Whilst narrative has been shown to be a fruitful context for eliciting language samples, assessments for adult users should be designed to suit the strengths, needs and values of adult signers with intellectual disabilities, using materials that are compatible with their life course stage rather than those designed for young children.

    Meuris, Kristien; Maes, Bea; Zink, Inge

    2015-08-01

    The goal of this study was to evaluate a key word signing (KWS) program in which adults with mild to severe intellectual disability (ID) were taught manual signs through their support staff. Our hypothesis was that spontaneous manual sign production of participants would increase significantly after 12 months of implementation of the KWS program. A KWS immersion program was implemented in a facility for adults with ID. First, 8 support workers received 8 hr of training. These KWS ambassadors then taught 2 manual signs per week to their colleagues, who modeled the use of the signs throughout the day in natural interactions with their clients. KWS use in 15 adults with ID and 15 of their support staff was evaluated before the start of the program and at a 12-month follow-up using a narrative task and during spontaneous conversation. Manual sign production of support workers and adults with ID had increased significantly 12 months after the start of the program. The adults with ID were able to express significantly more communicative functions in their narrative language after the intervention and when using KWS. The KWS program was successful and can be applied in similar clinical settings.

    Even though use of aided augmentative and alternative communication (AAC) by staff has been extensively researched, few studies relate to unaided AAC strategies such as key word signing (KWS). We explored the KWS views of two groups: direct support staff in group residential homes and teachers from special education secondary schools. We examined transcripts from individual semi-structured interviews with five direct support staff and five teachers using thematic analysis. Participants discussed consistency of KWS use and reasons for implementing KWS. Compared to direct support staff, teachers described more use of KWS throughout the day with more individuals with intellectual disability. Teachers discussed use of KWS to facilitate students' present and future interactions, while direct support staff primarily discussed immediate effects. Participants experienced KWS implementation as a learning process and aimed to turn the use of manual signs into a routine habit. This required considerable self-monitoring, and the effort that this continuous self-feedback required, combined with environmental factors, could hinder KWS implementation. These preliminary findings suggest that preservice KWS training and on-site KWS assistance may need to be enhanced.

    Visual search has been a long-standing problem in applications such as location recognition and product search. Much research has been done on image representation, matching, indexing, and retrieval. Key component technologies for visual search have been developed, and numerous real-world applications are emerging. To ensure application interoperability, the Moving Picture Experts Group (MPEG) has begun standardizing visuaJ search technologies and is developing the compact descriptors for visua) search (CDVS) standard. MPEG seeks to develop a collaborative platform for evaluating existing visual search technologies. Peking University has participated in this standardization since the 94th MPEG meeting, and significant progress has been made with the various proposals. A test model (TM) has been selected to determine the basic pipeline and key components of visual search. However, the first-version TM has high computational complexity and imperfect retrieval and matching. Core experiments have therefore been set up to improve TM. In this article, we summarize key technologies for visual search and report the progress of MPEG CDVS. We discuss Peking University' s efforts in CDVS and also discuss unresolved issues.

    Full Text Available Abstract Background Over the past ten years the promotion of recovery has become a stated aim of mental health policies within a number of English speaking countries, including Scotland. Implementation of a recovery approach involves a significant reorientation of mental health services and practices, which often poses significant challenges for reformers. This article examines how four key technologies of recovery have assisted in the move towards the creation of a recovery-oriented mental health system in Scotland. Methods Drawing on documentary analysis and a series of interviews we examine the construction and implementation of four key recovery 'technologies' as they have been put to use in Scotland: recovery narratives, the Scottish Recovery Indicator (SRI, Wellness Recovery Action Planning (WRAP and peer support. Results Our findings illuminate how each of these technologies works to instantiate, exemplify and disseminate a 'recovery orientation' at different sites within the mental health system in order to bring about a 'recovery oriented' mental health system. They also enable us to identify some of the factors that facilitate or hinder the effectiveness of those technologies in bringing about a change in how mental health services are delivered in Scotland. These finding provide a basis for some general reflections on the utility of 'recovery technologies' to implement a shift towards recovery in mental health services in Scotland and elsewhere. Conclusions Our analysis of this process within the Scottish context will be valuable for policy makers and service coordinators wishing to implement recovery values within their own national mental health systems.

    Many active magnetic shielding designs have been proposed in order to reduce the radiation exposure received by astronauts on long duration, deep space missions. While these designs are promising, they pose significant engineering challenges. This work presents a survey of the major systems required for such unconfined magnetic field design, allowing the identification of key technologies for future development. Basic mass calculations are developed for each system and are used to determine the resulting galactic cosmic radiation exposure for a generic solenoid design, using a range of magnetic field strength and thickness values, allowing some of the basic characteristics of such a design to be observed. This study focuses on a solenoid shaped, active magnetic shield design; however, many of the principles discussed are applicable regardless of the exact design configuration, particularly the key technologies cited.

    2011-01-01

    Full Text Available With the popularity of online shopping it is increasingly becoming important for manufacturers and service providers to ask customers to review their product and associated service. Typically the number of customer reviews that a product receives grows rapidly and can be in hundreds or even thousands. This makes it difficult for a potential customer to decide whether to buy the product or not. It is also difficult for the manufacturer of the product to keep track and manage customer opinions. Opinion mining is an emerging field that classifies a user opinion into positive and negative reviews. In this paper it is proposed to develop a methodology using word score based on Singular Value Decomposition by modeling a custom corpus for a given topic in which opinion mining has to be performed. Bayes Net and decision tree induction algorithms are used to classify the opinions.

    Aiming at the characteristics of modularity and reconfigurable in open architecture computer numerical control (CNC) system, the open architecture CNC system, Harbin Institute of Technology computer numerical control (HITCNC), is researched and manufactured based on the interface standards. The system's external interfaces are coincident with the corresponding international standards, and the internal interfaces follow the open modular architecture controller (OMAC) agreement.In the research and manufacturing process, object-oriented technology is used to ensure thc openness of the HITCNC, and static programming is applied in the CNC system according to the idea of modularization disassembly. The HITCNC also actualizes real-time and unreal-time modules adopting real-time dynamical linked library (RTDLL) and component object model (COM). Finite state machine (FSM) is adopted to do dynamically modeling of HITCNC. The complete separation between the software and the hardware is achieved in the HITCNC by applying the SoftSERCANS technique.The application of the above key techniques decreases the programming workload greatly, and uses software programs replacing hardware functions, which offers plenty technique ensures for the openness of HITCNC. Finally, based on the HITCNC, a three-dimensional milling system is established.On the system, series experiments are done to validate the expandability and interchangeability of HITCNC. The results of the experiments show that the established open architecture CNC system HITCNC is correct and feasible, and has good openness.

    The evolution of computer networks has experienced several major steps, and research focus of each step has been kept changing and evolving, from ARPANET to OSI/RM, then HSN (high speed network) and HPN (high performance network). During the evolution, computer networks represented by Internet have made great progress and gained unprecedented success. However, with the appearance and intensification of tussle, along with the three difficult problems (service customizing, resource control and user management) of modern network, it is found that traditional Internet and its architecture no longer meet the requirements of next generation network. Therefore, it is the next generation network that current Internet must evolve to. With the mindset of achieving valuable guidance for research on next generation network, this paper firstly analyzes some dilemmas facing current Internet and its architecture, and then surveys some recent influential research work and progresses in computer networks and related areas, including new generation network architecture, network resource control technologies, network management and security, distributed computing and middleware,wireless/mobile network, new generation network services and applications, and foundational theories on network modeling.Finally, this paper concludes that within the research on next generation network, more attention should be paid to the high availability network and corresponding architecture, key theories and supporting technologies.

  6. Key factors affecting the deployment of electricity generation technologies in energy technology scenarios

    Energy Technology Data Exchange (ETDEWEB)

    2009-12-15

    This report presents the findings of a survey of key factors affecting the deployment of electricity generation technologies in selected energy scenarios. The assumptions and results of scenarios, and the different models used in their construction, are compared. Particular attention is given to technology assumptions, such as investment cost or capacity factors, and their impact on technology deployment. We conclude that the deployment of available technologies, i.e. their market shares, can only be explained from a holistic perspective, and that there are strong interactions between driving forces and competing technology options within a certain scenario. Already the design of a scenario analysis has important impacts on the deployment of technologies: the choice of the set of available technologies, the modeling approach and the definition of the storylines determine the outcome. Furthermore, the quantification of these storylines into input parameters and cost assumptions drives technology deployment, even though differences across the scenarios in cost assumptions are not observed to account for many of the observed differences in electricity technology deployment. The deployment can only be understood after a consideration of the interplay of technology options and the scale of technology deployment, which is determined by economic growth, end-use efficiency, and electrification. Some input parameters are of particular importance for certain technologies: CO{sub 2} prices, fuel prices and the availability of carbon capture and storage appear to be crucial for the deployment of fossil-fueled power plants; maximum construction rates and safety concerns determine the market share of nuclear power; the availability of suitable sites represents the most important factor for electricity generation from hydro and wind power plants; and technology breakthroughs are needed for solar photovoltaics to become cost-competitive. Finally, this analysis concludes with a

    2003-12-01

    Nippon Telephone and Telegram Corporation (NTT) continues to develop the modular mesh-type deployable antenna. Antenna diameter can be changed from 5 m to about 20 m by changing the number of modules used with surface accuracy better than 2.4 mm RMS (including all error factors) with sufficient deployment reliability. Key technologies are the antenna's structural design, the deployment mechanism, the design tool, the analysis tool, and modularized testing/evaluation methods. This paper describes our beam steering mechanism. Tests show that it yields a beam pointing accuracy of better than 0.1°. Based on the S-band modular mesh antenna reflector, the surface accuracy degradation factors that must be considered in designing the new antenna are partially identified. The influence of modular connection errors on surface accuracy is quantitatively estimated. Our analysis tool SPADE is extended to include the addition of joint gaps. The addition of gaps allows non-linear vibration characteristics due to gapping in deployment hinges to be calculated. We intend to design a new type of mesh antenna reflector. Our new goal is an antenna for Ku or Ka band satellite communication. For this mission, the surface shape must be 5 times more accurate than is required for an S-band antenna.

    Religion, State and Civil Religion: Assumption and Practice of Confucian Religion in the Course of Nation-state Construction CAN Chun-song Abstract: In late Qing Dynasty and the early years of the Republic of China, Kang You-wei made a proposal to set Confucian religion as state religion. After analyzing carefully Kang's related texts, however, it can be shown that Kang had unique understandings of "religion" and "state religion". Kang defined Confucianism as religion in the sense of cultivation, and emphasized that the function of Confucianism was moral education. Kang's understanding of "state religion" aims to conserve Chinese traditional cultures and customs, shape the identity of nation-state, and enhance the state's cohesion. In this sense, Kang's definition of "national religion" is similar to to Bellah's "civil religion".

    In modern discussions among health professionals there is a strange lack of discussions of power. This is most notably true for the discussions about proper physician-patient relations and the discussions about trust. This article explores some of the consequences of this absence. It is argued that the absence of the issue of power hampers a serious and open moral discussion of important institutional forms in the health care system. It is also argued that some of the proposals for how to organize physician-patient interaction are rather unrealistic, mainly because the issue of power is neglected. Finally, the article develops some ideas about how power ought to be approached in modem health care.

    Reason, Rationality and Reasonableness: An Essay Inspired by Chen Jia-ying's Dianoesis Abstract: The theme of Chen Jia-ying's Dianoesis should be understood as "on the reasoning for reasoning" rather than simply "on reasoning". In order to understand "the reasoning for reasoning", it may be better to review the history of Western philosophy, in which the focus of attention has been moved from"reason" through "rationality" to "reasonableness". Moreover, interpreting "reason" not only as rationality but also as reasonableness may help us overcome the dilemma between reason-dogmatism and reason-nihilism. The idea of "reasonableness" that has been discussed by various contemporary Western philosophers is very similar to the idea of "li xing" that was proposed by Chinese philosopher Liang Shu-ming on the basis of his comparison between Chinese and Western cultures. For the sake of developing our tradition of li xing or reasonableness, however, we should not ignore some serious weaknesses in this tradition while cherishing its valuable elements.

    In view of the significant difficulties of propagation, planting and simple product in Dendrobium catenatum(D. officinale)industry development, a series of research were carried out. Genome study showed that D. catenatum is a specie of diploid with 38 chromosomes and 28 910 protein-coding genes. It was identified that specific genes accumulated in different organs at the transcriptome level. We got an insight into the gene regulation mechanism of the loss of the endospermous seed, the wide ecological adaptability and the synthesis of polysaccharides, which provided a theoretical basis for genetic engineering breeding and development and utilization of active pharmaceutical ingredients. The rapid propagation system was established for applying to industrialized production by overcoming breeding problems on seed setting and sprouting, which laid a foundation for artificial cultivation of D. catenatum. And in order to give a clear explanation of genetic variation of important economic traits, we built up the breeding system. Since special varieties of D. catenatum were bred, it helped solve the problem of trait segregation of seedling progeny and support the improvement of D. catenatum industry. The regulation of dynamic variation of target compounds, together with the mechanism of nutrient uptake, was revealed. The breakthrough of key technologies including culture substrates, light regulation and precisely collection was carried out. Several cultivation modes like facility cultivation, original ecological cultivation, cliff epiphytic cultivation, stereoscopic cultivation and potting cultivation were set up. Above all, the goal of cultivating D. catenatum as well as producing good D. catenatum will be achieved. Copyright© by the Chinese Pharmaceutical Association.

    The evaluation of language and communication skills in adults who use augmentative and alternative communication (AAC) in general and key word signing (KWS) in particular, can be an elaborate task. Besides being time-consuming and not very similar to natural communication, standard language tests often do not take AAC or KWS into account. Therefore, we developed a narrative task specifically for adults with intellectual disability (ID) who use KWS. The task was evaluated in a group of 40 adult KWS users. Outcome measures on the narrative task correlated significantly with measures of standard language and communication tests for verbal language, but not for use of manual signs. All narrative measures, for both verbal language and manual signing, correlated highly with similar measures from a conversation sample. The developed narrative task proved useful and valid to evaluate the language and communication skills of adults with ID taking into account both their verbal language and manual sign use.

    In services for adults with intellectual disabilities, various staff members may have different key word signing (KWS) skills and conversational style. Little is known about how these clients use KWS with different staff members. Therefore, we observed staff-client conversations and examined how clients' KWS usage was shaped by staff members' KWS usage and conversational style. Three 10-min dyadic conversations between an adult with moderate or severe intellectual disabilities (N = 15) and three familiar staff members were filmed and transcribed. The KWS usage and conversational responsivity in the transcriptions was analyzed at group (using generalized estimating equations), subgroup, and individual levels. Clients appeared to produce significantly more KWS as partners imitated more signs and as partners were more responsive. There was a negative interaction between these two factors. Subgroup analyses showed that spontaneity of clients' KWS usage was a continuum. Findings suggest that staff can encourage clients' KWS usage by imitating manual signs but that clients' response efficiency should also be taken into account.

    2015-07-01

    Full Text Available This paper examines the phenomenon of linguistic borrowings in general and the use of anglicisms in particular, in the contexts of globalization and the progress made in different domains, especially in the Information Technology domain. Borrowing is the phenomenon which undertakes the word transmission process from one language into another among the connected communities. The language that lends is the donor or the borrower language, and the language that borrows is known as the receptor or the borrowing language. Anglicisms are the English-loan words that are present in many European languages. The phenomenon of globalisation is the main topic of several contradictory and polarization discussions and undoubtedly globalisation is necessary and it is a fact in today’s world but the question is: what will be the long-term language consequences? There might be two situations: the consequences may be positive, such as ease of communication and perception, language economics and also negative: not understanding anglicisms resulting in disturbed communication, rejection of anglicisms, loss of semantic diversity of your own language, less and less possibilities of expressing yourself in your own language. We can mention that responsible for the impact of English is the prestige associated with this language. This language is generally held in highest regard by the younger generation of Romanians, who are easily influenced by the television, radio, movies, and other media that are supplied by British and American entertainment, which are considered to be trendy and cool. Each of those resources has influenced the Romanian population on numerous levels, creating new words and phrases in the Romanian language. In order to illustrate and discuss the pertinent or, on the contrary, the unjustified use of English-loan words in the field of Information Technology, the study will focus on a selection of articles published in the electronic Romanian issues

    This article introduces the fabrication technology processes of the capacitive pressure sensor based on the low temperature co-fired ceramic (LTCC) material. Filling the cavity with different materials as a sacrificial layer is mainly discussed, and two different materials are chosen in the fabrication. It is found that the cavity filled with polyimide expands largely during sintering, while carbon ESL49000 material filled is more preferable to keep the cavity flat. Finally, the structure leaving without an air evacuation channel is designed and tested in a built-up pressure environment, the frequency measured decreases approximately linearly with the pressure applied, which proves the design leaving no air evacuation channel advisable.

    The world population will continue to face biological threats, whether they are naturally occurring or intentional events. The speed with which diseases can emerge and spread presents serious challenges, because the impact on public health, the economy, and development can be huge. The U.S. government recognizes that global public health can also have an impact on national security. This global perspective manifests itself in U.S. policy documents that clearly articulate the importance of biosurveillance in providing early warning, detection, and situational awareness of infectious disease threats in order to mount a rapid response and save lives. In this commentary, we suggest that early recognition of infectious disease threats, whether naturally occurring or man-made, requires a globally distributed array of interoperable hardware and software fielded in sufficient numbers to create a network of linked collection nodes. We argue that achievement of this end state will require a degree of cooperation that does not exist at this time-either across the U.S. federal government or among our global partners. Successful fielding of a family of interoperable technologies will require interagency research, development, and purchase ("acquisition") of biosurveillance systems through cooperative ventures that likely will involve our strategic allies and public-private partnerships. To this end, we propose leveraging an existing federal interagency group to integrate the acquisition of technologies to enable global biosurveillance.

  19. Magnetic bearings: A key technology for advanced rocket engines?

    Girault, J. PH.

    1992-01-01

    For several years, active magnetic bearings (AMB) have demonstrated their capabilities in many fields, from industrial compressors to control wheel suspension for spacecraft. Despite this broad area, no significant advance has been observed in rocket propulsion turbomachinery, where size, efficiency, and cost are crucial design criteria. To this respect, Societe Europeenne de Propulsion (SEP) had funded for several years significant efforts to delineate the advantages and drawbacks of AMB applied to rocket propulsion systems. Objectives of this work, relative technological basis, and improvements are described and illustrated by advanced turbopump layouts. Profiting from the advantages of compact design in cryogenic environments, the designs show considerable improvements in engine life, performances, and reliability. However, these conclusions should still be tempered by high recurrent costs, mainly due to the space-rated electronics. Development work focused on this point and evolution of electronics show the possibility to decrease production costs by an order of magnitude.

  1. Radioisotope Power: A Key Technology for Deep Space Explorations

    Science.gov (United States)

    Schmidt, George R.; Sutliff, Thomas J.; Duddzinski, Leonard

    2009-01-01

    A Radioisotope Power System (RPS) generates power by converting the heat released from the nuclear decay of radioactive isotopes, such as Plutonium-238 (Pu-238), into electricity. First used in space by the U.S. in 1961, these devices have enabled some of the most challenging and exciting space missions in history, including the Pioneer and Voyager probes to the outer solar system; the Apollo lunar surface experiments; the Viking landers; the Ulysses polar orbital mission about the Sun; the Galileo mission to Jupiter; the Cassini mission orbiting Saturn; and the recently launched New Horizons mission to Pluto. Radioisotopes have also served as a versatile heat source for moderating equipment thermal environments on these and many other missions, including the Mars exploration rovers, Spirit and Opportunity. The key advantage of RPS is its ability to operate continuously, independent of orientation and distance relative to the Sun. Radioisotope systems are long-lived, rugged, compact, highly reliable, and relatively insensitive to radiation and other environmental effects. As such, they are ideally suited for missions involving long-lived, autonomous operations in the extreme conditions of space and other planetary bodies. This paper reviews the history of RPS for the U.S. space program. It also describes current development of a new Stirling cycle-based generator that will greatly expand the application of nuclear-powered missions in the future.

    Full Text Available Abstract Background Health Technology Reassessment (HTR is a structured, evidence-based assessment of the clinical, social, ethical and economic effects of a technology currently used in the health care system, to inform optimal use of that technology in comparison to its alternatives. Little is known about current international HTR practices. The objective of this research was to summarize experience-based information gathered from international experts on the development, initiation and implementation of a HTR program. Methods A mixed methods approach, using a survey and in-depth interviews, was adopted. The survey covered 8 concepts: prioritization/identification of potentially obsolete technologies; program development; implementation; mitigation; program championing; stakeholder engagement; monitoring; and reinvestment. Members of Health Technology Assessment International (HTAi and the International Network of Agencies for Health Technology Assessment (INAHTA formed the sampling frame. Participation was solicited via email and the survey was administered online using SurveyMonkey. Survey results were analyzed using descriptive statistics. To gather more in-depth knowledge, semi-structured interviews were conducted among organizations with active HTR programs. Interview questions were developed using the same 8 concepts. The hour-long interviews were recorded, transcribed and analyzed using constant comparative analysis. Results Ninety-five individuals responded to the survey: 49 were not discussing HTR, 21 were beginning to discuss HTR, nine were imminently developing a program, and 16 participants had programs and were completing reassessments. The survey results revealed that methods vary widely and that although HTR is a powerful tool, it is currently not being used to its full potential. Of the 16 with active programs, nine agreed to participate in follow-up interviews. Interview participants identified early and extensive stakeholder

Commentators often point to new medical technology as the key driver for burgeoning expenditures. This paper critically appraises this conjecture, based on an analysis of the existing literature, with the aim of offering a more detailed and considered analysis of this relationship. Several databases were searched to identify relevant literature. Various categories of studies (eg, multivariate and cost-effectiveness analyses were included to cover different perspectives, methodological approaches, and issues regarding the link between medical technology and costs. Selected articles were reviewed and relevant information was extracted into a standardized template and analyzed for key cross-cutting themes, ie, impact of technology on costs, factors influencing this relationship, and methodological challenges in measuring such linkages. A total of 86 studies were reviewed. The analysis suggests that the relationship between medical technology and spending is complex and often conflicting. Findings were frequently contingent on varying factors, such as the availability of other interventions, patient population, and the methodological approach employed. Moreover, the impact of technology on costs differed across technologies, in that some (eg, cancer drugs, invasive medical devices had significant financial implications, while others were cost-neutral or cost-saving. In light of these issues, we argue that decision-makers and other commentators should extend their focus beyond costs solely to include consideration of whether medical technology results in

    Although the two first metabolic needs are based on simple molecule (i.e. oxygen and water), the third metabolic needs considered a tremendously large number and diversity of molecules: food. Today, physical chemical technologies do not allow to synthetize all the spectrum of molecules and biological processes have to be considered. Moreover, the raw material products by plants or by microorganisms are generally not directly edible or palatable and would need either transformation, assembly and/or storage. In other words the challenges of the food cannot be reduced to the plant production but need to include as well the complete chain, from the production conditions and the biomass quality up to the final edible products and its acceptance. In other words all the steps have to be considered and characterize. Today these challenges requires a high level of plants characterization. This round table part 4 would allow the participants to present some of their results and express some domain of activities. Re4serach for collaboration will be identified.

    In this project we have developed a language model based on Artificial Neural Networks (ANNs) for use in conjunction with automatic textual search or speech recognition systems. The model can be trained on large corpora of text to produce probability estimates that would improve the ability of systems to identify words in a sentence given partial contextual information. The model uses a gradient-descent learning procedure to develop a metric of similarity among terms in a corpus, based on context. Using lexical categories based on this metric, a network can then be trained to do serial word probability estimation. Such a metric can also be used to improve the performance of topic-based search by allowing retrieval of information that is related to desired topics even if no obvious set of key words unites all the retrieved items.

    2017-09-01

    The aim of the present study was to examine the relationship between the use of key word signing (KWS) by support staff and by adults with intellectual disabilities (clients) who had experience with using KWS. Specifically, we explored whether these clients were more inclined to use KWS when support staff used KWS or imitated signs. One-to-one conversations between 24 clients and their support staff were filmed and transcribed. Partner turns were coded for communication mode (spoken or signed) and KWS response type (i.e., imitation, repetition, or new), while client turns were coded for communication mode and novelty (novel or non-novel). Using Cramer's V, strength of association was measured between each partner and subsequent client turn. Results indicated a moderate to strong association between partners' and clients' communication mode. In addition, partner turns containing newly introduced signs were associated with non-novel signed client turns, whereas sign imitations and repetitions by partners were more often followed by novel than non-novel signed client turns. These findings suggest that a balanced KWS input that includes new signed lexical items and sign imitations/repetitions may help to facilitate clients' KWS production and maintenance. This study was exploratory, and further research is needed to validate these results.

    1994-04-01

    The state-of-the-art of hydrogen storage technology is reviewed, including gaseous, liquid, hydride, surface adsorbed media, glass microsphere, chemical reaction, and liquid chemical technologies. The review of each technology includes a discussion of advantages, disadvantages, likelihood of success, and key research and development activities. A preferred technological path for the development of effective near-term hydrogen storage includes both cur-rent DOT qualified and advanced compressed storage for down-sized highly efficient but moderate range vehicles, and liquid storage for fleet vehicle applications. Adsorbate media are also suitable for fleet applications but not for intermittent uses. Volume-optimized transition metal hydride beds are also viable for short range applications. Long-term development of coated nanoparticulate or metal matrix high conductivity magnesium alloy, is recommended. In addition, a room temperature adsorbate medium should be developed to avoid cryogenic storage requirements. Chemical storage and oxidative schemes present serious obstacles which must be addressed for these technologies to have a future role.

Mechanism performances are analyzed in terms of the first and the second order influence coefficient matrix firstly. So the sizes of mechanism, which are better for all the performance indices of both kinematics and dynamics, can be confirmed and the restriction due to considering only the first order influence coefficient matrix in the past is broken through. Therefore, the theory basis for designing the mechanism size of novel engraving machine with better performances is provided. In addition, method for tool path planning and control technology for engraving force is also studied in the paper. The proposed algorithm for tool path planning on curved surface can be applied to arbitrary spacial curved surface in theory, control technology for engraving force based on fuzzy neural network(FNN has well adaptability to the changing environment. Research on teleoperation for parallel engraving machine based on B/S architecture resolves the key problems such as control mode, sharing mechanism for multiuser, real-time control for engraving job and real-time transmission for video information. Simulation results further show the feasibility and validity of the proposed methods.

    We present the key technologies and capabilities that will enable a future, large-aperture ultravioletopticalinfrared (UVOIR) space observatory. These include starlight suppression systems, vibration isolation and control systems, lightweight mirror segments, detector systems, and mirror coatings. These capabilities will provide major advances over current and near-future observatories for sensitivity, angular resolution, and starlight suppression. The goals adopted in our study for the starlight suppression system are 10-10 contrast with an inner working angle of 20 milliarcsec and broad bandpass. We estimate that a vibration and isolation control system that achieves a total system vibration isolation of 140 dB for a vibration-isolated mass of 5000 kg is required to achieve the high wavefront error stability needed for exoplanet coronagraphy. Technology challenges for lightweight mirror segments include diffraction-limited optical quality and high wavefront error stability as well as low cost, low mass, and rapid fabrication. Key challenges for the detector systems include visible-blind, high quantum efficiency UV arrays, photon counting visible and NIR arrays for coronagraphic spectroscopy and starlight wavefront sensing and control, and detectors with deep full wells with low persistence and radiation tolerance to enable transit imaging and spectroscopy at all wavelengths. Finally, mirror coatings with high reflectivity ( 90), high uniformity ( 1) and low polarization ( 1) that are scalable to large diameter mirror substrates will be essential for ensuring that both high throughput UV observations and high contrast observations can be performed by the same observatory.

    By means of a system of ecological criteria it can be demonstrated, that alternative solutions for a certain technical task often create different levels of ecological stress. The solution to be favoured for ecological reasons shows partly higher but also partly lower costs than the presently introduced solution. Ecologically optimized technologies may lead to a resubstitution of consumption of resources and environmental stress by capital and labour and consequently to an utilisation of presently unused production capacities. The earlier an adaption is introduced, the lower will be the required expense.

    The results of a study on the key technology of using shell sand, a kind of sea sand, as backfill for sea reclamation are described briefly. Laboratory tests show that the physical and mechanical properties of shell sand are as good as normal quartz sand. Based on the chemical test and durability test of shell sand it could be concluded that the influence of corrosion of shell sand by acid rain and sea water might be ignored in the evaluation of the safety and durability of the engineering project. The results of field improvement tests show that the bearing capacity of shell sand backfill foundation is more than 200 kPa after vibroflotation improvement or dynamic compaction improvement. The shell sand is a good backfill material for sea reclamation.

    Full Text Available Application of thematic classification of actual vocabulary as a whole to the formation of loan words allows to see the uniqueness of seperate groups of the vocabulary. English loan words prevail relating to the sphere of economy, science and technology, loan words from Arabic dominate from the religious vocabulary. Application of field approach to the analysis of actual religious Arabisms revealed both nuclear and peripheral components of the field. At the core of the field there are such Arabisms as Allah and Islam, which can be characterized as key words. However, in unifying the features of these words vary at a number of parameters. The word Allah has zero derivation productivity and at lexicographical description (as opposed to functioning in the language of the media is free of connotations. Arabism, Islam, by contrast, has a high derivation productivity and derived words can express evaluation. Lexicographic description of the Arabism Islam is also quite diverse stylistically and in contents. The core of the field “Muslim religion” also includes a number of words fixed in most modern dictionaries of foreign words. At the periphery of the field there are Arabisms that do not have high levels of frequency, but at the same time as an indicator of dominant Arabisms of religious content among topical Arabisms.

    The advance of the Internet and new technologies over the last decade has transformed the retailing panorama. More and more channels are emerging, causing consumers to change their habits and shopping behavior. An omnichannel strategy is a form of retailing that, by enabling real interaction, allows customers to shop across channels anywhere and at any time, thereby providing them with a unique, complete, and seamless shopping experience that breaks down the barriers between channels. This paper aims to identify the factors that influence omnichannel consumers' behavior through their acceptance of and intention to use new technologies during the shopping process. To this end, an original model was developed to explain omnichannel shopping behavior based on the variables used in the UTAUT2 model and two additional factors: personal innovativeness and perceived security. The model was tested with a sample of 628 Spanish customers of the store Zara who had used at least two channels during their most recent shopping journey. The results indicate that the key determinants of purchase intention in an omnichannel context are, in order of importance: personal innovativeness, effort expectancy, and performance expectancy. The theoretical and managerial implications are discussed. PMID:27516749

    Full Text Available The concept of Future Networks is based on the premise that current infrastructures require enhanced control, service customization, self-organization and self-management capabilities to meet the new needs in a connected society, especially of mobile users. In order to provide a high-performance mobile system, three main fields must be improved: radio, network, and operation and management. In particular, operation and management capabilities are intended to enable business agility and operational sustainability, where the addition of new services does not imply an excessive increase in capital or operational expenditures. In this context, a set of key-enabled technologies have emerged in order to aid in this field. Concepts such as Software Defined Network (SDN, Network Function Virtualization (NFV and Self-Organized Networks (SON are pushing traditional systems towards the next 5G network generation.This paper presents an overview of the current status of these promising technologies and ongoing works to fulfill the operational and management requirements of mobile infrastructures. This work also details the use cases and the challenges, taking into account not only SDN, NFV, cloud computing and SON but also other paradigms.

    In recent years, the increasing development of cloud computing technologies laid critical foundation for efficiently solving complicated geographic issues. However, it is still difficult to realize the cooperative operation of massive heterogeneous geographical models. Traditional cloud architecture is apt to provide centralized solution to end users, while all the required resources are often offered by large enterprises or special agencies. Thus, it's a closed framework from the perspective of resource utilization. Solving comprehensive geographic issues requires integrating multifarious heterogeneous geographical models and data. In this case, an open computing platform is in need, with which the model owners can package and deploy their models into cloud conveniently, while model users can search, access and utilize those models with cloud facility. Based on this concept, the open cloud service strategies for the sharing of heterogeneous geographic analysis models is studied in this article. The key technology: unified cloud interface strategy, sharing platform based on cloud service, and computing platform based on cloud service are discussed in detail, and related experiments are conducted for further verification.

    A worldwide growing interest in fast and secure data communications pushes technology development along two lines. While fast communications can be realized using laser communications in fiber and free-space, inherently secure communications can be achieved using quantum key distribution (QKD). By combining both technologies in a single device, many synergies can be exploited, therefore reducing size, weight and power of future systems. In recent experiments we demonstrated quantum communications over large distances as well as between an aircraft and a ground station which proved the feasibility of QKD between moving partners. Satellites thus may be used as trusted nodes in combination with QKD receiver stations on ground, thereby enabling fast and secure communications on a global scale. We discuss the previous experiment with emphasis on necessary developments to be done and corresponding ongoing research work of German Aerospace Center (DLR) and Ludwig Maximilians University Munich (LMU). DLR is performing research on satellite and ground terminals for the high-rate laser communication component, which are enabling technologies for the QKD link. We describe the concept and hardware of three generations of OSIRIS (Optical High Speed Infrared Link System) laser communication terminals for low Earth orbiting satellites. The first type applies laser beam pointing solely based on classical satellite control, the second uses an optical feedback to the satellite bus and the third, currently being in design phase, comprises of a special coarse pointing assembly to control beam direction independent of satellite orientation. Ongoing work also targets optical terminals for CubeSats. A further increase of beam pointing accuracy can be achieved with a fine pointing assembly. Two ground stations will be available for future testing, an advanced stationary ground station and a transportable ground station. In parallel the LMU QKD source size will be reduced by more than an

    The scramjet, which is the propulsion of hypersonic vehicle, has become the focus in many military developed countries. The ground tests play an important role in the research of scramjet. There is defect of test medium contamination (the thermochemical characteristic of the ground test medium is different from that of the flight medium) in existing ground test facilities for scramjet combustor experiment. To solve the problem of test medium contamination, the first clean air heated facility of China for scramjet combustor experiment is designed. The key technology of designing the clean air heated facility is summarized. By using bypass duct, combustor model is protected from high temperature. To reduce the switching time between main duct and bypass duct, solenoid valve and water-cooled system were used. Having centrosymmetric structure, the heat radiating area of the facility and heat loss of the facility are much lower than others. Clean air heated facility is adopted to conduct experiment, which is the first experiment of China in clean air inflow, research on hydrogen-fueled and ethylene-fueled ignition and combustion for scramjet combustor at different equivalence ratio. Successful ignition and sustained combustion of hydrogen has been achieved. Successful ethylene ignition and sustained main stream combustion is achieved with normal fuel injection and taking hydrogen as pilot flame. Experiment result shows that the wall pressure of combustor model rises when the equivalence ratio of hydrogen rises. As the wall pressure of combustor model rises, the pressure disturbance influences the shock train in the upstream.

    2012-04-01

    Proofreading (i.e., reading text for the purpose of detecting and correcting typographical errors) is viewed as a component of the activity of revising text and thus is a necessary (albeit not sufficient) procedural step for enhancing the quality of a written product. The purpose of the present research was to test competing accounts of word-error detection which predict factors that may influence reading and proofreading differently. Word errors, which change a word into another word (e.g., from --> form), were selected for examination because they are unlikely to be detected by automatic spell-checking functions. Consequently, their detection still rests mostly in the hands of the human proofreader. Findings highlighted the weaknesses of existing accounts of proofreading and identified factors, such as length and frequency of the error in the English language relative to frequency of the correct word, which might play a key role in detection of word errors.

    This study investigated the use of a word processor for enhancing the academic outcomes of three students with writing disabilities in a junior high school. A single-subject ABAB design was used to compare academic output produced during class time with and without a computer equipped with a word processor. The number of spelling errors, the number of reading errors, and the number of words used per text were counted, and the overall structure and organization of text were examined across all in-class materials. The data demonstrated a clear difference between handwritten and computer phases. In traditional paper-and-pencil phases, students produced outcomes that had more spelling mistakes, more reading errors, and lower overall quality of organization and structure in comparison with the phases in which a computer equipped with a word processor was used. The results did not indicate any noticeable difference in the number of words per text. Implications and future research directions are discussed.

    Full Text Available The Yuanba Gasfield is a large gas field discovered by Sinopec in the Sichuan Basin in recent years, and another main exploration area for natural gas reserves and production increase after the Puguang Gasfield. The ultra-deep sour gas reservoir in the Yuanba Gasfield is characterized by complicated geologic structure, deep reservoirs and complex drilled formation, especially in the continental deep strata which are highly abrasive with low ROP (rate of penetration and long drilling period. After many years of drilling practice and technical research, the following six key drilling and completion technologies for this type reservoir are established by introducing new tools and technologies, developing specialized drill bits and optimizing drilling design. They are: casing program optimization technology for ROP increasing and safe well completion; gas drilling technology for shallow continental strata and high-efficiency drilling technology for deep high-abrasion continental strata; drilling fluid support technologies of gas–liquid conversion, ultra-deep highly-deviated wells and horizontal-well lubrication and drag reduction, hole stability control and sour gas contamination prevention; well cementing technologies for gas medium, deep-well long cementing intervals and ultra-high pressure small space; horizontal-well trajectory control technologies for measuring instrument, downhole motor optimization and bottom hole assembly design; and liner completion modes and completion string optimization technologies suitable for this gas reservoir. Field application shows that these key technologies are contributive to ROP increase and efficiency improvement of 7000 m deep horizontal wells and to significant operational cycle shortening.

    How often a given word is used, relative to other words, can convey information about the word's linguistic utility. Using Google word data for 3 languages over the 209-year period 1800-2008, we found by analyzing word use an anomalous recent change in the birth and death rates of words, which indicates a shift towards increased levels of competition between words as a result of new standardization technology. We demonstrate unexpected analogies between the growth dynamics of word use and the growth dynamics of economic institutions. Our results support the intriguing concept that a language's lexicon is a generic arena for competition which evolves according to selection laws that are related to social, technological, and political trends. Specifically, the aggregate properties of language show pronounced differences during periods of world conflict, e.g. World War II.

    2015-10-01

    Full Text Available The case-study aims to examine the effectiveness of training of morphological structure on the spelling of compounds by a spelling-disabled primary school student. The experimental design of the intervention was based on the word-pair paradigm and included a pre-test, a training program and a post-test (n= 50 pairs. The Training Program aimed to offer systematic, targeted and step-by-step instruction of morphological decomposition of words to the student and delivered via the Smart Notebook educational software. The intervention had a substantial impact in enhancing the spelling of compounds by the individual. Especially, instructional gains were statistically significant, and generalized substantially to untrained but analogous words and pseudowords in terms of structure and common stems. These findings are particularly important for the development of alternative approaches to the educational interventions of individuals with spelling difficulties and developmental dyslexia, and are consistent with the experimental literature.

    Science.gov (United States)

    O'Connor, Thomas F; Yu, Lawrence X; Lee, Sau L

    2016-07-25

    Issues in product quality have produced recalls and caused drug shortages in United States (U.S.) in the past few years. These quality issues were often due to outdated manufacturing technologies and equipment as well as lack of an effective quality management system. To ensure consistent supply of safe, effective and high-quality drug products available to the patients, the U.S. Food and Drug Administration (FDA) supports modernizing pharmaceutical manufacturing for improvements in product quality. Specifically, five new initiatives are proposed here to achieve this goal. They include: (i) advancing regulatory science for pharmaceutical manufacturing; (ii) establishing a public-private institute for pharmaceutical manufacturing innovation; (iii) creating incentives for investment in the technological upgrade of manufacturing processes and facilities; (iv) leveraging external expertise for regulatory quality assessment of emerging technologies; and (v) promoting the international harmonization of approaches for expediting the global adoption of emerging technologies.

    2016-10-01

    Full Text Available The dolomite reservoirs of the Lower Cambrian Longwangmiao Fm in the Gaoshiti–Moxi area, Sichuan Basin, are deeply buried (generally 4400–4900 m, with high heterogeneity, making reservoir prediction difficult. In this regard, key seismic exploration technologies were developed through researches. Firstly, through in-depth analysis on the existing geologic, drilling, seismic data and available research findings, basic surface and subsurface structures and geologic conditions within the study area were clarified. Secondly, digital seismic data acquisition technologies with wide azimuth, wide frequency band and minor bins were adopted to ensure even distribution of coverage of target formations through optimization of the 3D seismic geometry. In this way, high-accuracy 3D seismic data can be acquired through shallow, middle and deep formations. Thirdly, well-control seismic data processing technologies were applied to enhance the signal-to-noise ratio (SNR of seismic data for deep formations. Fourthly, a seismic response model was established specifically for the Longwangmiao Fm reservoir. Quantitative prediction of the reservoir was performed through pre-stack geo-statistics. In this way, plan distribution of reservoir thicknesses was mapped. Fifthly, core tests and logging data analysis were conducted to determine gas-sensitive elastic parameters, which were then used in pre-stack hydrocarbon detection to eliminate the multiple solutions in seismic data interpretation. It is concluded that application of the above-mentioned key technologies effectively promote the discovery of largescale marine carbonate gas reservoirs of the Longwangmiao Fm.

    Wagner, G. A.; Kadereit, A.

    Geoarchaeology is a growing discipline in archaeological science. It aims at the natural environment as context of past human societies and at the interaction between both, the environment and man as part of a joint ecosystem. This topic is also of considerable concern of present societies. Like other historic sciences, geoarchaeology requires accurate chronologies. Since one deals in geoarchaeology predominantly with sediments and rocks, luminescence methods play a key role. This is demonstrated in two case studies from Phlious in southern Greece and Nasca in southern Peru. The results show clearly climatically triggered social developments and feedbacks to the environment.

    Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made.

    Full Text Available The four diversion tunnels at Jinping II hydropower station represent the deepest underground project yet conducted in China, with an overburden depth of 1500–2000 m and a maximum depth of 2525 m. The tunnel structure was subjected to a maximum external water pressure of 10.22 MPa and the maximum single-point groundwater inflow of 7.3 m3/s. The success of the project construction was related to numerous challenging issues such as the stability of the rock mass surrounding the deep tunnels, strong rockburst prevention and control, and the treatment of high-pressure, large-volume groundwater infiltration. During the construction period, a series of new technologies was developed for the purpose of risk control in the deep tunnel project. Nondestructive sampling and in-situ measurement technologies were employed to fully characterize the formation and development of excavation damaged zones (EDZs, and to evaluate the mechanical behaviors of deep rocks. The time effect of marble fracture propagation, the brittle–ductile–plastic transition of marble, and the temporal development of rock mass fracture and damage induced by high geostress were characterized. The safe construction of deep tunnels was achieved under a high risk of strong rockburst using active measures, a support system comprised of lining, grouting, and external water pressure reduction techniques that addressed the coupled effect of high geostress, high external water pressure, and a comprehensive early-warning system. A complete set of technologies for the treatment of high-pressure and large-volume groundwater infiltration was developed. Monitoring results indicated that the Jinping II hydropower station has been generally stable since it was put into operation in 2014.

    Full Text Available Mega-sport events such as Olympic Games or Football World Cup are always presented as providing the hosting nation and/or city with huge benefits. Supporters of such events quote economic, social and cultural impacts for the region as well as contributions to scientific and technological progress and innovation. obviously, they need to politically justify the impressive and growing financial investment required by organizing Olympic Games or World Cup. The article aims at looking at a quite abundant academic literature with the objectives of defining the various potential impacts and the methods used for their assessment. It concludes that there is no universal and scientifically valid model for evaluating the benefits of mega-sport events and that organizers should be very cautious when arguing in favor of deciding to host such events.

    Yacht has become a fashionable way for entertainment. However, to obtain the precise location of a yacht docked at a port has become one of the concerns of a yacht manager. To deal with this issue, we adopt a positioning method based on the principle of binocular parallax and background difference in this paper. Binocular parallax uses cameras to get multi-dimensional perspective of the yacht based on geometric principle of imaging. In order to simplify the yacht localization problem, we install LED light indicator as the key point on a yacht. And let it flash at a certain frequency during day time and night time. After getting the distance between the LED and the cameras, locating the yacht is easy. Compared with other traditional positioning methods, this method is simpler and easier to implement. In this paper, we study the yacht positioning method using the LED indicator. Simulation experiment is done for a yacht model in the distance of 3 meters. The experimental result shows that our method is feasible and easy to implement with a small 15% positioning error.

    Prediction has become more and more difficult in mineral exploration, especially in the mature exploration environment such as Tongling copper district. For enhancing predictive discovery of hidden ore deposits in such mature environment, the key strategies which should be adopted include the innovation of the exploration models, application of the advanced exploration techniques and integration of multiple sets of information. The innovation of the exploration models should incorporate the new metallogenic concepts that are based on the geodynamic anatomization. The advanced techniques applied in the mature exploration environment should aim at the speciality and complexity of the geological setting and working environments. The information synthesis is to integrate multiple sets of data for giving a more credible and visual prospectivity map by using the geographic imformation system(GIS) and several mathematical methods, such as weight of evidence and fuzzy logic, which can extract useful information from every set of data as much as possible. Guided by these strategies, a predictive exploration in Fenghuangshan ore field of Tongling copper district was implemented, and a hidden ore deposit was discovered.

    The United States ranking among the world in science, technology, engineering, and mathematics (STEM) education is decreasing. To counteract this problem NASA has made it part of its mission to promote STEM education among the nation s youth. Mockups can serve as a great tool when promoting STEM education in America. The Orion Cockpit Working Group has created a new program called Students Shaping America s Next Space Craft (SSANS) to outfit the Medium Fidelity Orion Mockup. SSANS will challenge the students to come up with unique designs to represent the flight design hardware. There are two main types of project packages created by SSANS, those for high school students and those for university students. The high school projects will challenge wood shop, metal shop and pre-engineering classes. The university projects are created mainly for senior design projects and will require the students to perform finite element analysis. These projects will also challenge the undergraduate students in material selection and safety requirements. The SSANS program will help NASA in its mission to promote STEM education, and will help to shape our nations youth into the next generation of STEM leaders.

    Year 2000 will be remembered as an epoch making period between two Koreas. Korean nuclear industries became activated with the KEDO LWR main contracts entering into force in February, 2000. Respective design, manufacturing and construction activities are mobilized in accordance with the total project schedule of about 100 months. What started out as the nuclear power plant design standardization project in the early '80s, is now being implemented as repeat construction of KSNPs at Yonggwang and Ulchin sites as well as at Kumho site in the DPRK. However, the KEDO construction schedule and the past nuclear inconsistency issues are closely linked due to the nonproliferation concerns. In practice, the IAEA must come to the conclusion that the correctness and completeness must be fulfilled before delivery of the first key component for the KEDO LWR unit 1. While the IAEA verification process tends to focus on the nuclear materials accountancy control, longer term objective between two Koreas is bound to take the form of confidence building. It is necessary to analyse the nuclear research and production facilities in order to make proper evaluation of a nation's nuclear capabilities. Close assessment on development status of graphite moderated reactors and their operation history, spent fuel reprocessing facilities, and HEU production capabilities would be essential. In addition, illicit trafficking possibilities should be addressed. Chapter 1 describes the graphite moderated reactors in general; Chapter 2 describes various reprocessing processes and their detection capabilities; Chapter 3 contains possible uranium enrichment processes with their detection capabilities, and Chapter 4 summarizes the international treaties in illicit trafficking control with the IAEA database.

    This program was organized to focus on materials development issues critical to the acceleration of solid-state lighting, and was split into three major thrust areas: (1) study of dislocation density reduction for GaN grown on sapphire using 'cantilever epitaxy', and the impact of dislocation density on the performance of state-of-the-art high-power LEDs; (2) the evaluation of in situ techniques for monitoring gas phase chemistry and the properties of GaN-based layers during metal-organic vapor phase epitaxy (MOCVD), and (3) feasibility for using semiconductor nanoparticles ('quantum dots') for the down-conversion of blue or ultraviolet light to generate white light. The program included a partnership between Lumileds Lighting (epitaxy and device fabrication for high power LEDs) and Sandia National Laboratories (cantilever epitaxy, gas phase chemistry, and quantum dot synthesis). Key findings included: (1) cantilever epitaxy can provide dislocation density reduction comparable to that of more complicated approaches, but all in one epitaxial growth step; however, further improvements are required to realize significant gains in LED performance at high drive currents, (2) in situ tools can provide detailed knowledge about gas phase chemistry, and can be used to monitor and control epitaxial layer composition and temperature to provide improved yields (e.g., a fivefold increase in color targeting is demonstrated for 540nm LEDs), and (3) quantum efficiency for quantum dots is improved and maintained up to 70% in epoxy thin films, but further work is necessary to increase densification (absorption) and robustness before practical application to LEDs.

    Abney, Morgan B.; Perry, Jay L.

    2016-01-01

    Over the last 55 years, NASA has evolved life support for crewed space exploration vehicles from simple resupply during Project Mercury to the complex and highly integrated system of systems aboard the International Space Station. As NASA targets exploration destinations farther from low Earth orbit and mission durations of 500 to 1000 days, life support systems must evolve to meet new requirements. In addition to having more robust, reliable, and maintainable hardware, limiting resupply becomes critical for managing mission logistics and cost. Supplying a crew with the basics of food, water, and oxygen become more challenging as the destination ventures further from Earth. Aboard ISS the Atmosphere Revitalization Subsystem (ARS) supplies the crew's oxygen demand by electrolyzing water. This approach makes water a primary logistics commodity that must be managed carefully. Chemical reduction of metabolic carbon dioxide (CO2) provides a method of recycling oxygen thereby reducing the net ARS water demand and therefore minimizing logistics needs. Multiple methods have been proposed to achieve this recovery and have been reported in the literature. However, depending on the architecture and the technology approach, "oxygen recovery" can be defined in various ways. This discontinuity makes it difficult to compare technologies directly. In an effort to clarify community discussions of Oxygen Recovery, we propose specific definitions and describe the methodology used to arrive at those definitions. Additionally, we discuss key performance parameters for Oxygen Recovery technology development including challenges with comparisons to state-of-the-art.

    Children tend to infer that when a speaker uses a new label, the label refers to an unlabeled object rather than one they already know the label for. Does this inference reflect a default assumption that words are mutually exclusive? Or does it instead reflect the result of a pragmatic reasoning...... process about what the speaker intended? In two studies, we distinguish between these possibilities. Preschoolers watched as a speaker pointed toward (Study 1) or looked at (Study 2) a familiar object while requesting the referent for a new word (e.g. 'Can you give me the blicket?'). In both studies......, despite the speaker's unambiguous behavioral cue indicating an intent to refer to a familiar object, children inferred that the novel label referred to an unfamiliar object. These results suggest that children expect words to be mutually exclusive even when a speaker provides some kinds of pragmatic...

    2001-01-01

    With the rapid development of Internet electr onic commerce has been n oticed increasingly. However, the problem of its security makes people not dare into this advanced field. The subjects involving in electronic commerce activiti es need to prevent the other subjects from denying their activities. Some securi ty organizations of government also need to get the encrypted key through legal means in order to track, intercept and capture criminal information. Thus the en crypted key escrow technology must be adopted and it must be of security. For th e sake of security the key will be divided into several blocks which are stored in different reliable agents. The key can not be restored unless all agents w ork together. For designing an effective and safe key escrow, the discrete logar ithm is applied for solving key escrow .The security of this algorithm completel y depends on the difficulty to solve discrete logarithm ,therefore, this algorit hm is secure and simple when a big prime number is adopted.Moreover, adding thi s technology in SET will benefit the legal agency to monitor illegal activitie s.%电子商务随着Internet的迅速发展,日益受到人们的关注。但其安全问题经常令人不敢涉足其中。一方面参加商务活动的主体需防止另一方抵赖活动,另一方面政府安全机构为跟踪截获犯罪嫌疑人员的通信,都需要通过合法渠道获得电子商务中商务活动的主体进行数据通讯时的加密密钥。此时需采用密钥托管技术,而且密钥托管必须是安全的。为了安全起见,密钥被分成几块,分别存在几位可信赖的委托人处进行托管,任何一位委托人都不能单独恢复密钥。只有几位委托人在一起才能回复密钥。为了有效安全的进行密钥托管,采用了离散对数解决密钥托管。鉴于本算法的安全性依赖与求离散对数的困难性,所以当选用很大的安全素数时,此算法既简单又安全。

  10. Word Domain Disambiguation via Word Sense Disambiguation

    Energy Technology Data Exchange (ETDEWEB)

    Sanfilippo, Antonio P.; Tratz, Stephen C.; Gregory, Michelle L.

    2006-06-04

    Word subject domains have been widely used to improve the perform-ance of word sense disambiguation al-gorithms. However, comparatively little effort has been devoted so far to the disambiguation of word subject do-mains. The few existing approaches have focused on the development of al-gorithms specific to word domain dis-ambiguation. In this paper we explore an alternative approach where word domain disambiguation is achieved via word sense disambiguation. Our study shows that this approach yields very strong results, suggesting that word domain disambiguation can be ad-dressed in terms of word sense disam-biguation with no need for special purpose algorithms.

    acquisition therefore presents us with the opportunity to examine how children respond to the task of word learning when the input language offers less clear cues to syllabic structure than usually seen. To investigate the sound structure in Danish children’s lexical development, we need a model of syllable...... structure; and as the theoretical basis for our analyses related to sonority we present Basbøll’s Sonority Syllable Model for phonotactics, which is based upon a non-circular version of a sonority hierarchy. We investigate spontaneous child language output in a longitudinal corpus with two children aged 9......Syllables play an important role in children’s early language acquisition, and children appear to rely on clear syllabic structures as a key to word acquisition (Vihman 1996; Oller 2000). However, not all languages present children with equally clear cues to syllabic structure, and since...

  7. Word recognition using ideal word patterns

    Science.gov (United States)

    Zhao, Sheila X.; Srihari, Sargur N.

    1994-03-01

    The word shape analysis approach to text recognition is motivated by discoveries in psychological studies of the human reading process. It attempts to describe and compare the shape of the word as a whole object without trying to segment and recognize the individual characters, so it bypasses the errors committed in character segmentation and classification. However, the large number of classes and large variation and distortion expected in all patterns belonging to the same class make it difficult for conventional, accurate, pattern recognition approaches. A word shape analysis approach using ideal word patterns to overcome the difficulty and improve recognition performance is described in this paper. A special word pattern which characterizes a word class is extracted from different sample patterns of the word class and stored in memory. Recognition of a new word pattern is achieved by comparing it with the special pattern of each word class called ideal word pattern. The process of generating the ideal word pattern of each word class is proposed. The algorithm was tested on a set of machine printed gray scale word images which included a wide range of print types and qualities.

  11. From Word Alignment to Word Senses, via Multilingual Wordnets

    Directory of Open Access Journals (Sweden)

    Dan Tufis

    2006-05-01

    Full Text Available Most of the successful commercial applications in language processing (text and/or speech dispense with any explicit concern on semantics, with the usual motivations stemming from the computational high costs required for dealing with semantics, in case of large volumes of data. With recent advances in corpus linguistics and statistical-based methods in NLP, revealing useful semantic features of linguistic data is becoming cheaper and cheaper and the accuracy of this process is steadily improving. Lately, there seems to be a growing acceptance of the idea that multilingual lexical ontologisms might be the key towards aligning different views on the semantic atomic units to be used in characterizing the general meaning of various and multilingual documents. Depending on the granularity at which semantic distinctions are necessary, the accuracy of the basic semantic processing (such as word sense disambiguation can be very high with relatively low complexity computing. The paper substantiates this statement by presenting a statistical/based system for word alignment and word sense disambiguation in parallel corpora. We describe a word alignment platform which ensures text pre-processing (tokenization, POS-tagging, lemmatization, chunking, sentence and word alignment as required by an accurate word sense disambiguation.

  16. Research to practice in addiction treatment: key terms and a field-driven model of technology transfer.

    Science.gov (United States)

    2011-09-01

    The transfer of new technologies (e.g., evidence-based practices) into substance abuse treatment organizations often occurs long after they have been developed and shown to be effective. Transfer is slowed, in part, due to a lack of clear understanding about all that is needed to achieve full implementation of these technologies. Such misunderstanding is exacerbated by inconsistent terminology and overlapping models of an innovation, including its development and validation, dissemination to the public, and implementation or use in the field. For this reason, a workgroup of the Addiction Technology Transfer Center (ATTC) Network developed a field-driven conceptual model of the innovation process that more precisely defines relevant terms and concepts and integrates them into a comprehensive taxonomy. The proposed definitions and conceptual framework will allow for improved understanding and consensus regarding the distinct meaning and conceptual relationships between dimensions of the technology transfer process and accelerate the use of evidence-based practices.

    Different nations have different social cultures, and the social culture of every nation is developing with the devel-opment of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in con-ceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.

  14. When is a word a word?

    Science.gov (United States)

    Vihman, M M; McCune, L

    1994-10-01

    Although adult-based words co-occur in the period of transition to speech with a variety of non-word vocalizations, little attention has been given to the formidable problem of identifying these earliest words. This paper specifies explicit, maximally 'inclusive' identification procedures, with criteria based on both phonetic and contextual parameters. A formal system for evaluating phonetic match is suggested, as well as a set of child-derived functional categories reflecting use in context. Analysis of word use across two samples of 10 children each, followed from 0;9 to 1;4, provides evidence to suggest that context-bound words can be 'trained' by focusing on eliciting language, but that the timing of context-flexible word use remains independent of such training.

  3. The CubeSat Infrared Atmospheric Sounder (CIRAS): Demonstrating key technologies for a future constellation to improve temporal sampling

    Science.gov (United States)

    Pagano, T. S.

    2016-12-01

    Hyperspectral infrared sounding of the atmosphere has become a vital element in the observational system for weather forecast prediction at National Weather Prediction (NWP) centers worldwide. The NASA Atmospheric Infrared Sounder (AIRS) instrument was the pathfinder for the hyperspectral infrared observations and was designed to provide accurate atmospheric temperature and water vapor profile information in support of weather prediction. AIRS was launched in 2002 and continues to operate well. The Cross-track Infrared Sounder (CrIS) on the Suomi NPP satellite was launched in 2011 to continue the AIRS measurement record. CrIS also continues to operate well and additional sensors are planned for launch promising to continue the hyperspectral infrared measurements in support of NWP into the late 2030's. The high cost of IR sounders makes it costly to launch them into multiple orbits to improve temporal sampling, or into GEO, although EUMETSAT is planning a GEO IR Sounder to launch in the early 2020's. JPL NASA is offering an alternate hyperspectral IR sounder architecture for the future involving CubeSats. The latest technology in large format focal plane assemblies, wide field optics and active cryocoolers enables a reduction in size, mass and cost of the legacy sounders and offer new configurations. Lessons learned from AIRS and CrIS indicate that temperature and water vapor sounding in the lower troposphere can be achieved with only the MWIR portion of the spectrum. The CubeSat Infrared Atmospheric Sounder (CIRAS) employs only an MWIR spectrometer to achieve lower tropospheric temperature and water vapor profiles, but with comparable spatial, spectral and radiometric sensitivity in this band as AIRS and CrIS. CIRAS operates from 4.08-5.13 µm with 625 channels and spectral resolution of 1.2-2.0 cm-1. CIRAS employs an immersion grating spectrometer making the optics incredibly compact, and HOT-BIRD detectors enabling good uniformity and operability over the large

  4. ICEHTMC 2015特别供稿专栏%Key Considerations for the Introduction of a Healthcare Technology Management Program in Remote Locations

    Institute of Scientific and Technical Information of China (English)

    J B Robson

    2016-01-01

    Establishment of a healthcare technology management program in remote locations requires the same consideration as programs in mainstream healthcare facilities but with an added emphasis on clarity of process, ownership of responsibility, management of resources and communication of roles. The author shares the experiences of clinical engineering personnel from the South Australian Biomedical Engineering Service (SA BME) based in Adelaide who are often required to travel thousands of kilometers by road to provide onsite assistance at over 100 rural and city sites. Effective remote service delivery requires a reliance on site based healthcare workers and local contractors to help manage the clinical engineering issues and risks associated with owning or using healthcare technology with an added role for SA BME staff to manage, foster and regulate this assistance. This paper outlines the policy document published throughout South Australia by the state government’s health department, directing all stakeholders involved in the use and ownership of healthcare technology on their role in the Management of Healthcare Technology. With an emphasis on assuring this technology is safe, effective, available and compliant this policy directive is an example of an essential foundation document that should exist wherever clinical engineering services are applied including sites where no clinical engineering personnel are based. This paper outlines the key elements of this directive, how it was developed and how it is used to achieve clarity of process and ownership of roles. Of essential importance when establishing a healthcare technology management program is its nexus with relevant industry, country and global philosophies. In Australia fundamental technology management principles are collated through Standards Australia the nation's peak non-government Standards organization charged by the Commonwealth Government to meet Australia's need for contemporary, internationally

    The magnitude of the impact of search engine marketing on trademark law has started contested issues involving infringement of search engine company~s using key words to search advertising trade- marks. Advertisers buy words or phrases including trademarks from search engine companies for the users to search and sometimes bounces out the ads of their own products and services, which causes the protec- tion of trademark rights and the trade mark infringement of search engine companies. Most American courts hold that buying trade-marks as key words search purpose in fact forms the use of commercial usage of the trademarks. And this was going on without the knowledge of the consumers. When the consumers search these key words trade marks, they will misunderstand it as authorized by the trademark owner or think that search results have vital interest relationships with the trademark owners. But till now, the courts haven~t judged this behavior as trademarks confusion.%互联网搜索引擎业务的发展对商标法产生了巨大的冲击,其中带来的一个热点问题就是搜索引擎公司涉嫌关键词检索广告商标侵权。广告发布者从搜索引擎商那里购买包括商标名称在内的词语供网络用户检索,并弹出自己产品或者服务的广告,这就引发了商标权的保护问题及搜索引擎商的商标侵权责任问题。大多数美国法院认为购买商标作为检索的关键词构成商标的商业使用,这种行为也是在消费者不知情的情况下进行的,消费者在网络上检索这些商标关键词时,有可能认为是获得了商标权人的授权或者是搜索的结果与商标权人有利害关系。尽管如此,美国法院迄今为止还没有判决此种行为构成商标混淆。

  12. Internationalization, education and technological innovation: three key factors to improve the quality of the environment and public health

    Directory of Open Access Journals (Sweden)

    Giordano Urbini

    2015-01-01

    Full Text Available The environment and the health of mankind are subject to strong pressures from pollutants. The ambition of a better quality of life is often frustrated by the increase in emissions as a result of the increasing consumption of resources and energy to satisfy the growth of the world’s population and its expectations for socioeconomic development. At times, problems take on a planetary dimension, the best known example being greenhouse gas emission, with the resulting effects of climate change. Pollution highlights our failure to provide adequate education, which is essential if we are to become fully aware of problems and actively seek sustainable solutions. To this end, it is essential to set up an extended environmental and health education program in all communities that will accompany younger generations from the beginning of their education in order to make them conscious players in protecting the environment and their own health. The size of the problems requires that a joint effort be made at an international level in the political realm and in the scientific-cultural realm in order to share experiences and sensitivity and to seek joint solutions. It is necessary to assign an increasingly important role to scientific and technological innovation which, in the last century, from Marconi to Einstein to Fleming, to the most recent innovations in the fields of genomics and microchips, has allowed humanity to achieve a rate of growth of wellbeing never previously seen in its thousands of years of history. This innovation must rationally be entrusted with our expectations to provide a practical solution to the problems of pollution that threaten our everyday lives and the survival of the planet. This text discusses the types of progress most eagerly awaited in the fields of water supply, wastewater treatment, atmospheric pollution and waste disposal.

    Measures to improve the quality and sustainability of healthcare practice and provision have become a policy concern. In addition, the involvement of stakeholders in health policy decision-making has been advocated, as complex questions arise around the structure of funding arrangements in a context of limited resources. Using a case study of assisted reproductive technologies (ART), deliberative engagements with a range of stakeholder groups were held on the topic of how best to structure the distribution of Australian public funding in this domain. Deliberative engagements were carried out with groups of ART consumers, clinicians and community members. The forums were informed by a systematic review of ART treatment safety and effectiveness (focusing, in particular, on maternal age and number of treatment cycles), as well as by international policy comparisons, and ethical and cost analyses. Forum discussions were transcribed and subject to thematic analysis. Each forum demonstrated stakeholders' capacity to understand concepts of choice under resource scarcity and disinvestment, and to countenance options for ART funding not always aligned with their interests. Deliberations in each engagement identified concerns around 'equity' and 'patient responsibility', culminating in a broad preference for (potential) ART subsidy restrictions to be based upon individual factors rather than maternal age or number of treatment cycles. Community participants were open to restrictions based upon measures of body mass index (BMI) and smoking status, while consumers and clinicians saw support to improve these factors as part of an ART treatment program, as distinct from a funding criterion. All groups advocated continued patient co-payments, with measures in place to provide treatment access to those unable to pay (namely, equity of access). Deliberations yielded qualitative, socially-negotiated evidence required to inform ethical, accountable policy decisions in the specific

    This study is the first in a series designed to develop and norm new theoretically motivated sentence tests for children. The purpose was to examine the independent contributions of word frequency (i.e., how often words occur in language) and lexical density (the number of similar sounding words or "neighbors" to a target word) to the perception of key words in the new sentence set. Twenty-four children with normal hearing aged 5 to 12 yrs served as participants; they were divided into four equal age-matched groups. The stimuli consisted of 100 semantically neutral sentences that were 5 to 7 words in length. Each sentence contained 3 key words that were controlled for word frequency and lexical density. Words with few neighbors come from sparse neighborhoods, whereas words with many neighbors come from dense neighborhoods. The key words within a sentence belonged to one of the four lexical categories: (1) high-frequency sparse, (2) low-frequency dense, (3) high-frequency dense, and (4) low-frequency sparse. Participants were administered the sentence list and the 300 key words in isolation at 65 dB SPL. Each participant group was tested in spectrally matched noise at one of the four signal-to-noise ratios (SNRs -2, 0, 2, and 4 dB). The percent of words correctly identified was calculated as a function of SNR, key word context (sentences vs. words), and key word lexical category. SNR had a significant effect on the recognition of key words in sentences and in isolation; performance improved at higher SNRs. There were significant main effects of word frequency and lexical density as well as a significant interaction between the two lexical factors. In isolation, high-frequency words were recognized more accurately than low-frequency words. In both word and sentence contexts, sparse words yielded greater accuracy than dense words, irrespective of word frequency. There was a modest but significant negative correlation between lexical density and the recognition of

    2014-06-01

    Full Text Available The article presents the properties of exogenous word-formation system taking into account the existence of two word-formation systems in modern German. On the basis of foreign research which reveal modern trends in German word-formation connected with the internationalization and the development of new European Latin language. The author defines key features of exogenous word-formation, i.e. foreign origin of wordformation units, unmotivated units, unmotivated interchange in base and affixes as well as limited distribution rules in combination with German word-formation. The article analyzes various approaches to word-division, as well as motivated and unmotivated interchange of consonants in bases and in affixes. Unmotivated interchange showcases a special status of the exogenous word-formation within German. Another item covered by the article is the issue of confix. The article has opinions of researchers about correctness of its separation and a list of its features. The author presents his definition of confix: a confix is a bound exogenous word-formation unit with a certain lexical and semantic meaning and joining other units directly or indirectly (through linking morpheme -o-, which is able to make a base. Moreover, some confixes are able to participate at word-combination and have unlimited distribution. So far, confix showcases the integration of exogenous word-formation and traditional German word-formation. The research proves the special status of exogenous word-formation in German. Its results can be used as a base for further analysis of co-existing word-formation systems in German and determination of their characteristic features.

  1. Acquired prosopagnosia without word recognition deficits.

    2015-01-01

    It has long been suggested that face recognition relies on specialized mechanisms that are not involved in visual recognition of other object categories, including those that require expert, fine-grained discrimination at the exemplar level such as written words. But according to the recently proposed many-to-many theory of object recognition (MTMT), visual recognition of faces and words are carried out by common mechanisms [Behrmann, M., & Plaut, D. C. ( 2013 ). Distributed circuits, not circumscribed centers, mediate visual recognition. Trends in Cognitive Sciences, 17, 210-219]. MTMT acknowledges that face and word recognition are lateralized, but posits that the mechanisms that predominantly carry out face recognition still contribute to word recognition and vice versa. MTMT makes a key prediction, namely that acquired prosopagnosics should exhibit some measure of word recognition deficits. We tested this prediction by assessing written word recognition in five acquired prosopagnosic patients. Four patients had lesions limited to the right hemisphere while one had bilateral lesions with more pronounced lesions in the right hemisphere. The patients completed a total of seven word recognition tasks: two lexical decision tasks and five reading aloud tasks totalling more than 1200 trials. The performances of the four older patients (3 female, age range 50-64 years) were compared to those of 12 older controls (8 female, age range 56-66 years), while the performances of the younger prosopagnosic (male, 31 years) were compared to those of 14 younger controls (9 female, age range 20-33 years). We analysed all results at the single-patient level using Crawford's t-test. Across seven tasks, four prosopagnosics performed as quickly and accurately as controls. Our results demonstrate that acquired prosopagnosia can exist without word recognition deficits. These findings are inconsistent with a key prediction of MTMT. They instead support the hypothesis that face

  9. On the word ponentino

    Directory of Open Access Journals (Sweden)

    Alvaro Alonso

    2009-06-01

    Full Text Available This work studies a very specific use of the word ponentino: It is used as a synonym of ‘Spaniard’ or, in a slightly more general context, as a word to refer to ‘people from the Western Mediterranean’, where Western Mediterranean stands for the Mediterranean sea stretching to the west of Sicily. Therefore, such a use of the word splits the interior sea into two halves, which do neither correspond with the old division between the Western Empire and the Byzantine Empire nor the clash between the Christian world and the Ottoman Empire. We propose an Italian origin for this particular use of the word.

  5. Word-identification priming for ignored and attended words

    Science.gov (United States)

    Stone, M.; Ladd, S. L.; Vaidya, C. J.; Gabrieli, J. D.

    1998-01-01

    Three experiments examined contributions of study phase awareness of word identity to subsequent word-identification priming by manipulating visual attention to words at study. In Experiment 1, word-identification priming was reduced for ignored relative to attended words, even though ignored words were identified sufficiently to produce negative priming in the study phase. Word-identification priming was also reduced after color naming relative to emotional valence rating (Experiment 2) or word reading (Experiment 3), even though an effect of emotional valence upon color naming (Experiment 2) indicated that words were identified at study. Thus, word-identification priming was reduced even when word identification occurred at study. Word-identification priming may depend on awareness of word identity at the time of study.

  16. Word generalization by a dog (Canis familiaris: is shape important?

    Directory of Open Access Journals (Sweden)

    Emile van der Zee

    Full Text Available We investigated the presence of a key feature of human word comprehension in a five year old Border Collie: the generalization of a word referring to an object to other objects of the same shape, also known as shape bias. Our first experiment confirmed a solid history of word learning in the dog, thus making it possible for certain object features to have become central in his word comprehension. Using an experimental paradigm originally employed to establish shape bias in children and human adults we taught the dog arbitrary object names (e.g. dax for novel objects. Two experiments showed that when briefly familiarized with word-object mappings the dog did not generalize object names to object shape but to object size. A fourth experiment showed that when familiarized with a word-object mapping for a longer period of time the dog tended to generalize the word to objects with the same texture. These results show that the dog tested did not display human-like word comprehension, but word generalization and word reference development of a qualitatively different nature compared to humans. We conclude that a shape bias for word generalization in humans is due to the distinct evolutionary history of the human sensory system for object identification and that more research is necessary to confirm qualitative differences in word generalization between humans and dogs.

    The automatic disambiguation of word senses (i.e., the identification of which of the meanings is used in a given context for a word that has multiple meanings) is essential for such applications as machine translation and information retrieval, and represents a key step for developing the so-called Semantic Web. Humans disambiguate words in a straightforward fashion, but this does not apply to computers. In this paper we address the problem of Word Sense Disambiguation (WSD) by treating texts as complex networks, and show that word senses can be distinguished upon characterizing the local structure around ambiguous words. Our goal was not to obtain the best possible disambiguation system, but we nevertheless found that in half of the cases our approach outperforms traditional shallow methods. We show that the hierarchical connectivity and clustering of words are usually the most relevant features for WSD. The results reported here shine light on the relationship between semantic and structural parameters of ...

    The input of a network is the key problem for Chinese word sense disambiguation utilizing the neural network. This paper presents an input model of the neural network that calculates the mutual information between contextual words and the ambiguous word by using statistical methodology and taking the contextual words of a certain number beside the ambiguous word according to ( - M, + N). The experiment adopts triple-layer BP Neural Network model and proves how the size of a training set and the value of M and N affect the performance of the Neural Network Model. The experimental objects are six pseudowords owning three word-senses constructed according to certain principles. The tested accuracy of our approach on a closed-corpus reaches 90. 31% ,and 89. 62% on an open-corpus. The experiment proves that the Neural Network Model has a good performance on Word Sense Disambiguation.

    Speech carries accent information relevant to determining the speaker's linguistic and social background. A series of web-based experiments demonstrate that accent cues can modulate access to word meaning. In Experiments 1-3, British participants were more likely to retrieve the American dominant meaning (e.g., hat meaning of "bonnet") in a word association task if they heard the words in an American than a British accent. In addition, results from a speeded semantic decision task (Experiment 4) and sentence comprehension task (Experiment 5) confirm that accent modulates on-line meaning retrieval such that comprehension of ambiguous words is easier when the relevant word meaning is dominant in the speaker's dialect. Critically, neutral-accent speech items, created by morphing British- and American-accented recordings, were interpreted in a similar way to accented words when embedded in a context of accented words (Experiment 2). This finding indicates that listeners do not use accent to guide meaning retrieval on a word-by-word basis; instead they use accent information to determine the dialectic identity of a speaker and then use their experience of that dialect to guide meaning access for all words spoken by that person. These results motivate a speaker-model account of spoken word recognition in which comprehenders determine key characteristics of their interlocutor and use this knowledge to guide word meaning access.

    For the large number of low-frequency words in .foreign language vocabulary acquisition, the strategy many experts in language teaching methods have been advocating is to teach the students the ways to guess .from context. However, two American scholars, Schatz and Baldwin (1986), on the basis of their experiments made on American students, argued that contextual clues are unreliable predictors of word meanigs.Context does not usually provide clues, but inhibit the correct prediction of word meanings just as o[ten as they facilitate them.

    A double occurrence word $w$ over a finite alphabet $\\Sigma$ is a word in which each alphabet letter appears exactly twice. Such words arise naturally in the study of topology, graph theory, and combinatorics. Recently, double occurrence words have been used for studying DNA recombination events. We develop formulas for counting and enumerating several elementary classes of double occurrence words such as palindromic, irreducible, and strongly-irreducible words.

    The paper presents a study on the tests on several key technologies,.i.e.reasonable value and hom-ogenization of track stiffness,the machining value of switch rail,switch kinematic gauge optimization,and the effect of siding layout on the riding quality of an EMU train passing through the turnouts.The testing has been conducted to research these technologies.The test results show that the selection of appropriate track stiffness in turnout area must be combined with the fastener characteristics to improve riding quality.The homogeniza-tion of track stiffness is realizable theoretically.But it is influenced by factors such as the construction quality and turnout fine-tuning.The switch rail relief against the stock rail determines the transition range and scale of wheel-rail vertical force between switch and stock rails,and directly influences the riding quality of the train passing through the turnouts.Geometric regularity of turnouts and riding quality will be affected if the switch rail relief is too high.The kinematic gauge optimization technology has no significant influence on the turnout geometry,The fact that kinematic gauge optimization technology is not applied to the turnouts of passenger dedicated lines is j ustified by the test data.The maximum values of carbody lateral acceleration were under 1 . 5 m/s2 when EMU trains passed the #42 and #62 turnouts.These results are consistent with the technical re-quirements and design expectations.%对岔区轨道刚度合理取值及均匀化技术、尖轨降低值优化技术、转辙器运动学轨距优化技术、侧线线型设计技术对动车组高速直、侧向过岔平稳性的影响进行了试验研究。研究结论如下:为保证旅客乘坐舒适性,必须结合采用的扣件特点选择合适的岔区轨道刚度,刚度均匀化在理论上可以实现,实际上受施工质量以及道岔精调状态等因素影响;尖轨相对于基本轨的降低值决定了轮轨垂直力在尖轨和基

    The article examines the relationship between God, prophet and the people in the Book of Jeremiah. The analysis shows a close connection, almost an identification, between the divine word (and consequently God himself) and the prophet, so that the prophet becomes a metaphor for God. This is done...... through exegetical studies of the call narrative (Jer 1), the Temple Sermon (Jer 7) and narratives about the prophet's seclusion from the people (e.g. Jer 16). In addition there is an analysis of Jer 36, the chapter telling about the writing down of the Book of Jeremiah. The main message of this chapter...

  2. Key technology for treating slack coal blockage in CBM recovery: A case study from multi-lateral horizontal wells in the Qinshui Basin

    Directory of Open Access Journals (Sweden)

    Yong Yang

    2016-01-01

    Full Text Available Due to the nature of coal bed, slack coal production is inevitable in gas recovery sby water drainage. When coalbed methane (CBM wells are reentered after low energy exploitation and shut-in, the negative effect of slack coal production on productivity of CBM is irreversible. In this paper, the CBM occurrence characteristics and multi-lateral horizontal well trajectory in the Qinshui Basin, Shanxi Province, were analyzed. In the multi-lateral horizontal wells, the expected gas production rate could not be reached and the production rate after shut-in maintenance could not restore to the level before shut-in. The reason for these issues is that migration pathways in the reservoirs are blocked by slack coal deposits, while formation water and slack coal deposit accumulated at the troughs of horizontal sections enlarge the resistance for gas to flow into the bottom hole. Furthermore, three key technologies to deal with slack coal blockage were proposed. Firstly, CBM horizontal well trajectory should follow the principle of keeping the wellbores smooth and updip instead of being “wavy”, on the premise of guaranteeing CBM drilling rate. Secondly, the cavities of production wells, as an important part of multi-lateral horizontal wells, are capable of settling sand, and can be used for gas–liquid–solid separation. And thirdly, a tree-like horizontal well with its main hole set on stable seam top or floor, provides a stable well flushing passage for coal powder. This research provides a useful attempt in solving the problem of slack coal production in gas recovery by water drainage.

    2010-10-01

    While the English language boasts a century of research into its most frequently-used words, no such attempt has ever formally been made in the Arab world. This pioneering study presents a list of 500 commonly-used words in the Arabic language based on compilations of words gathered from a number of popular reading series in Lebanon, spanning grades K to 3. This list can serve as a powerful tool for language teachers—who face several challenges posed by the inherent nature of Arabic in terms of diglossia, orthography and morphology—and provide them with a handy list of words for their pupils. The study has its limitations in terms of scope, breadth and the nature of the technology used for counting words. Nonetheless, it makes a number of recommendations for the future, including the development of a readability formula based on this list, the expansion of the scope of this word list and improvement to increase its technical accuracy.

    Zhang, Xujin; Samuel, Arthur G

    2015-01-01

    The current study investigated how listeners understand English words that have shorter words embedded in them. A series of auditory-auditory priming experiments assessed the activation of six types of embedded words (2 embedded positions × 3 embedded proportions) under different listening conditions. Facilitation of lexical decision responses to targets (e.g., pig) associated with words embedded in primes (e.g., hamster) indexed activation of the embedded words (e.g., ham). When the listening conditions were optimal, isolated embedded words (e.g., ham) primed their targets in all six conditions (Experiment 1a). Within carrier words (e.g., hamster), the same set of embedded words produced priming only when they were at the beginning or comprised a large proportion of the carrier word (Experiment 1b). When the listening conditions were made suboptimal by expanding or compressing the primes, significant priming was found for isolated embedded words (Experiment 2a), but no priming was produced when the carrier words were compressed/expanded (Experiment 2b). Similarly, priming was eliminated when the carrier words were presented with one segment replaced by noise (Experiment 3). When cognitive load was imposed, priming for embedded words was again found when they were presented in isolation (Experiment 4a), but not when they were embedded in the carrier words (Experiment 4b). The results suggest that both embedded position and proportion play important roles in the activation of embedded words, but that such activation only occurs under unusually good listening conditions.

  14. Words are not things

    Science.gov (United States)

    Moore, J.

    2000-01-01

    On a traditional view, words are the fundamental units of verbal behavior. They are independent, autonomous things that symbolically represent or refer to other independent, autonomous things, often in some other dimension. Ascertaining what those other things are constitutes determining the meaning of a word. On a behavior-analytic view, verbal behavior is ongoing, functional operant activity occasioned by antecedent factors and reinforced by its consequences, particularly consequences that are mediated by other members of the same verbal community. Functional relations rather than structure select the response unit. The behavior-analytic point of view clarifies such important contemporary issues in psychology as (a) the role of scientific theories and explanations, (b) educational practices, and (c) equivalence classes, so that there is no risk of strengthening the traditional view that words are things that symbolically represent other things.

    Lyrics from 155 songs written by the Lennon-McCartney team were scored using the Dictionary of Affect in Language. Resultant scores (pleasantness, activation, and imagery of words) were compared across key signatures using one way analyses of variance. Words from songs written in minor keys were less pleasant and less active than those from songs written in major keys. Words from songs written in the key of F scored extremely low on all three measures. Lyrics from the keys of C, D, and G were relatively active in tone. Results from Dictionary scoring were compared with assignments of character to keys made more than one century ago and with current musicians' opinions.

    Full Text Available The Bouyei language is divided into three vernaculars, the southern vernacular, the central vernacular and the southwestern vernacular. This paper aims to describe the lexicology of the southern vernacular of the Bouyei language focusing on word formation process. Bouyei words are formed by affixing, compounding and reduplicating. First, the affixation consists of prefixing and suffixing. Infixing is not found in this language. Second, the compound is divided into the semantic and syntactic compound. Finally, the reduplication is divided into the simple and complex reduplication. The simple reduplication is normally used to emphasize the meaning of the root or to indicate plurality.
