This proposed model is a form of telecommunication that allows exchange of data and voice via Wi-Fi network. The phones, which are Wi-Fi enabled and have android operating system, can be used to communicate with each other through the Wi-Fi communication channel. Proposed system incorporates messaging (Text and voice, conferencing (group conversation and file sharing services through the Wi-Fi network. When users enters the Wi-Fi network, proposed system displays the list of other users they are having this system on their mobile in that network. Using the system services, user can communicate with other user by exchanging packets to IP address of destination user, with the condition that both communicating person should be in same Wi-Fi network. The proposed system allows communication through Wi-Fi which requires neither any internet connectivity nor any service from the service providers. In this paper, the proposed system shall eliminate the usage of service providers for short-distance calls and decreases the cost that gets accrued in the consumer’s monthly bill. This system allows free conferencing, file sharing and messaging services within the Wi-Fi network that will greatly reduce the communication cost in large organizations.

  4. Launch Control System Message Reduction

    System Monitoring and Control (SMC) message browsers receive many messages daily that operators do not need to see. My job is to reduce the number of messages so that warning and emergency messages can be seen easily and therefore, responded to promptly. There are two methods to reduce messages: duplicate and state-based message correlations. With duplicate message correlation, SMC display the message the first time it shows up. The next times it occurs, a duplicate number will count the number of times the message appears. State-based message correlation is a process in which more informative messages acknowledge less useful ones and send them to history. I also work on correcting the severity level and text formats of messages. I follow two SMC message filtering tenets as I'm working on this project. Firstly, before filtering an offending message, a non-conformance (NC) must be created in order to attempt fixing that message through hardware or software. Only after the NC assessment states that it cannot fix an offending message, it can be filtered by SMC. Secondly, per Launch Control System (LCS) Coding Standards, SMC does not send information messages to the active message browser unless it's a response to an operator action.

    The program at Naval Air Development Center was initiated to determine the desirability of interactive voice systems for use in airborne weapon systems crew stations. A voice recognition and synthesis system (VRAS) was developed and incorporated into a human centrifuge. The speech recognition aspect of VRAS was developed using a voice command system (VCS) developed by Scope Electronics. The speech synthesis capability was supplied by a Votrax, VS-5, speech synthesis unit built by Vocal Interface. The effects of simulated flight on automatic speech recognition were determined by repeated trials in the VRAS-equipped centrifuge. The relationship of vibration, G, O2 mask, mission duration, and cockpit temperature and voice quality was determined. The results showed that: (1) voice quality degrades after 0.5 hours with an O2 mask; (2) voice quality degrades under high vibration; and (3) voice quality degrades under high levels of G. The voice quality studies are summarized. These results were obtained with a baseline of 80 percent recognition accuracy with VCS.

    2014-02-01

    To determine the difference in delivery success of health messages delivered through pushed SMS, pushed voice messages sent to personal phones, and voice messages retrieved from a community phone ("retrieved voice messaging"), as well as the difference in quality of the user experience. We analyzed the project's electronic monitoring data between September 2011 and June 2013, including demographics, enrollment data, and messages sent and successfully delivered. We also collected and analyzed information from quarterly phone-based surveys with users to assess quality of the user experience, including acceptability, comprehension, new information learned, and reported behavior change. More than half of subscribers enrolled in the retrieved voice messaging service while nearly one-third enrolled in the pushed SMS service and less than 10% in pushed voice messaging. Message delivery success was highest among pushed SMS subscribers and lowest among retrieved voice subscribers. Overall, 99% of survey respondents reported trusting messages they received, and about 75% of respondents recalled the last message they received and learned something new. Almost 75% of respondents reported that they had already changed or intended to change their behavior based on received messages. Intended or actual behavior change was significantly higher among pushed SMS enrollees than among pushed or retrieved voice messaging enrollees (P = .01). All message modalities led to high levels of satisfaction, comprehension, and new information learned. Due to lower cost, higher delivery success, and higher levels of intended or actual behavior change, SMS is the preferred delivery modality. However, the majority of users included in this study did not have access to a personal phone, and retrieved voice messages provided an opportunity to access a population that otherwise could not be served. Providing multiple methods by which users could access the service was crucial in extending reach

    1975-01-01

    The speech messages issued by voice warning systems must be carefully designed in accordance with general principles of human decision making processes, human speech comprehension, and the conditions in which the warnings can occur. The operator's effectiveness must not be degraded by messages that are either inappropriate or difficult to comprehend. Important experimental variables include message content, linguistic redundancy, signal/noise ratio, interference with concurrent tasks, and listener expectations generated by the pragmatic or real world context in which the messages are presented.

    2013-03-01

    Mobile Health (mHealth) has emerged as a promising direction for delivery of healthcare services via mobile communication devices such as cell phones. Examples include texting-based interventions for chronic disease monitoring, diabetes management, control of hypertension, smoking cessation, monitoring medication adherence, appointment keeping and medical test result delivery; as well as improving patient-provider communication, health information communication, data collection and access to health records. While existing messaging systems very well support bulk messaging and some polling applications, they are not designed for data collection and processing of health research oriented studies. For that reason known studies based on text-messaging campaigns have been constrained in participant numbers. In order to empower healthcare promotion and education research, this paper presents a system dedicated for healthcare research. It is designed for convenient communication with various study groups, feedback collection and automated processing.

    2003-04-01

    We have assembled a system using a personal computer workstation equipped with standard office software, an audio system, speech recognition software and an inexpensive radio-based wireless microphone that permits laboratory workers to enter or modify data while performing other work. Speech recognition permits users to enter data while their hands are holding equipment or they are otherwise unable to operate a keyboard. The wireless microphone allows unencumbered movement around the laboratory without a ''tether'' that might interfere with equipment or experimental procedures. To evaluate the potential of voice data entry in a laboratory environment, we developed a prototype relational database that records the disposal of radionuclides and/or hazardous chemicals Current regulations in our laboratory require that each such item being discarded must be inventoried and documents must be prepared that summarize the contents of each container used for disposal. Using voice commands, the user enters items into the database as each is discarded. Subsequently, the program prepares the required documentation.

    2011-05-01

    This study presents an evaluation of driver performance while text messaging via handheld mobile phones and an in-vehicle texting system. Participants sent and received text messages while driving with an experimenter on a closed-road course, using their personal mobile phones and the vehicle's system. The test vehicle was an instrumented 2010 Mercury Mariner equipped with an OEM in-vehicle system that supports text messaging and voice control of mobile devices via Bluetooth, which was modified to allow text message sending during driving. Twenty participants were tested, 11 younger (19-34) and 9 older (39-51). All participants were regular users of the in-vehicle system, although none had experience with the texting functions. Results indicated that handheld text message sending and receiving resulted in higher mental demand, more frequent and longer glances away from the roadway, and degraded steering measures compared to baseline. Using the in-vehicle system to send messages showed less performance degradation, but still had more task-related interior glance time and higher mental demand than baseline; using the system's text-to-speech functionality for incoming messages showed no differences from baseline. These findings suggest that using handheld phones to send and receive text messages may interfere with drivers' visual and steering behaviors; the in-vehicle system showed improvement, but performance was not at baseline levels during message sending.

    Osborn, Chandra Y; Mulvaney, Shelagh A

    2013-05-01

    Low-income, racial/ethnic minorities are often nonadherent to diabetes medications, have uncontrolled glycemia, and have high rates of diabetes-related morbidity. Cell phones provide a viable modality to support medication adherence, but few cell phone-based interventions have been designed for low-income persons, a population with more feature phone penetration than smartphone penetration. In an effort to reach the broadest range of patients, we leveraged the voice and text messaging capabilities shared by all cell phones to design the MEssaging for Diabetes intervention. We specifically advanced and adapted an existing tailored text messaging system to include interactive voice response functionality and support the medication adherence barriers of low-income, diverse adults with type 2 diabetes mellitus. We report on the design process and feasibility testing results (i.e., technical use patterns and subjective user experiences) from patients from the target population who used the intervention in one of three user-centered design iterations. The types of challenges encountered in design were related to providing text message content with valued information and support that engages patients. The design process also highlighted the value of obtaining mixed methods data to provide insight into legitimate versus illegitimate missing data, patterns of use, and subjective user experiences. The iterative testing process and results outlined here provide a potential template for other teams seeking to design technology-based self-care support solutions for comparable patient populations.

    The Message Reporting System (MRS) in the ATLAS data acquisition system (DAQ) is one package of the Online Software which acts as a glue of various elements of DAQ, High Level Trigger (HLT) and Detector Control System (DCS). The aim of the MRS is to provide a facility which allows all software components in ATLAS to report messages to other components of the distributed DAQ system. The processes requiring a MRS are on one hand applications that report error conditions or information and on the other hand message processors that receive reported messages. A message reporting application can inject one or more messages into the MRS at any time. An application wishing to receive messages can subscribe to a message group according to defined criteria. The application receives messages that fulfill the subscription criteria when they are reported to MRS. The receiver message processing can consist of anything from simply logging the messages in a file/terminal to performing message analysis. The inter-process communication is achieved using the CORBA technology. The design, architecture and the used technology of MRS are reviewed in this paper.

With the advancement in voice recognition it becomes easier to issue commands regarding directions to the visually impaired.

  19. Improving Quality of Voice Conversion Systems

    Science.gov (United States)

    Farhid, M.; Tinati, M. A.

    New improvement scheme for voice conversion are proposed in this paper. We take Human factor cepstral coefficients (HFCC), a modification of MFCC that uses the known relationship between center frequency and critical bandwidth from human psychoacoustics to decouple filter bandwidth from filter spacing, as the basic feature. We propose U/V (Unvoiced/Voiced) decision rule such that two sets of codebooks are used to capture the difference between unvoiced and voiced segments of the source speaker. Moreover, we apply three schemes to refine the synthesized voice, including pitch refinement, energy equalization, and frame concatenation. The acceptable performance of the voice conversion system can be verified through ABX listening test and MOS grad.

    Smith, Danford S.

    2015-01-01

    The NASA Goddard Mission Services Evolution Center (GMSEC) system is a message-based plug-and-play open system architecture used in many of NASA mission operations centers. This presentation will focus on the use of GMSEC standard messages to report and analyze the status of a system and enable the automation of the system's components. In GMSEC systems, each component reports its status using a keep-alive message and also publishes status and activities as log messages. In addition, the components can accept functional directive messages from the GMSEC message bus. Over the past several years, development teams have found ways to utilize these messages to create innovative display pages and increasingly sophisticated approaches to automation. This presentation will show the flexibility and value of the message-based approach to system awareness and automation.

    Full Text Available Este trabajo presenta un método de ocultamiento del mensaje para transmisión de señales de voz utilizando codificación por medio de bancos de filtros multi-resolución de análisis y de síntesis para la Transformada de Ondita Haar Discreta. Por medio de un banco de filtros Haar multi-resolución se realiza la separación de la señal en sus componentes y después se realiza una distorsión reversible de la síntesis multi-resolución de sus señales componentes, obteniendo una señal de salida que, aunque mantiene la misma información de la señal de entrada, el mensaje de la señal de voz que esta porta queda oculto en ella misma. Este método puede aplicarse para la transmisión codificada de señales de voz ya sea en su forma digital o analógica, y por su simplicidad resulta adecuado para implementarse en sistemas electrónicos digitales, ya sea como un arreglo de compuertas programables por campo, o como circuito integrado de aplicación específica.This work introduces a message concealment method for voice signals transmission using codification through multi-resolution filter banks implementation for analysis and synthesis for the Discrete Haar Wavelet Transform. Through these multi-resolution filter banks of Haar wavelet the voice signal can be split in its components, and later a reversible distortion of the synthesis of its multi-resolution component signals is made, obtaining an output signal that, although maintains the same information of the original input signal, hides the message of the carried voice signal in itself. This method can be applied in codified transmission of voice, analog or digital signals, and due to the simplicity of the method it’s suitable to be implemented on digital electronic systems like FPGA, or ASIC.

  6. METHODS FOR QUALITY ENHANCEMENT OF USER VOICE SIGNAL IN VOICE AUTHENTICATION SYSTEMS

    2014-03-01

    Full Text Available The reasonability for the usage of computer systems user voice in the authentication process is proved. The scientific task for improving the signal/noise ratio of the user voice signal in the authentication system is considered. The object of study is the process of input and output of the voice signal of authentication system user in computer systems and networks. Methods and means for input and extraction of voice signal against external interference signals are researched. Methods for quality enhancement of user voice signal in voice authentication systems are suggested. As modern computer facilities, including mobile ones, have two-channel audio card, the usage of two microphones is proposed in the voice signal input system of authentication system. Meanwhile, the task of forming a lobe of microphone array in a desired area of voice signal registration (100 Hz to 8 kHz is solved. The usage of directional properties of the proposed microphone array gives the possibility to have the influence of external interference signals two or three times less in the frequency range from 4 to 8 kHz. The possibilities for implementation of space-time processing of the recorded signals using constant and adaptive weighting factors are investigated. The simulation results of the proposed system for input and extraction of signals during digital processing of narrowband signals are presented. The proposed solutions make it possible to improve the value of the signal/noise ratio of the useful signals recorded up to 10, ..., 20 dB under the influence of external interference signals in the frequency range from 4 to 8 kHz. The results may be useful to specialists working in the field of voice recognition and speaker’s discrimination.

    2005-01-01

    The Internet Voice Distribution System (IVoDS) is a voice-communication system that comprises mainly computer hardware and software. The IVoDS was developed to supplement and eventually replace the Enhanced Voice Distribution System (EVoDS), which, heretofore, has constituted the terrestrial subsystem of a system for voice communications among crewmembers of the International Space Station (ISS), workers at the Payloads Operations Center at Marshall Space Flight Center, principal investigators at diverse locations who are responsible for specific payloads, and others. The IVoDS utilizes a communication infrastructure of NASA and NASArelated intranets in addition to, as its name suggests, the Internet. Whereas the EVoDS utilizes traditional circuitswitched telephony, the IVoDS is a packet-data system that utilizes a voice over Internet protocol (VOIP). Relative to the EVoDS, the IVoDS offers advantages of greater flexibility and lower cost for expansion and reconfiguration. The IVoDS is an extended version of a commercial Internet-based voice conferencing system that enables each user to participate in only one conference at a time. In the IVoDS, a user can receive audio from as many as eight conferences simultaneously while sending audio to one of them. The IVoDS also incorporates administrative controls, beyond those of the commercial system, that provide greater security and control of the capabilities and authorizations for talking and listening afforded to each user.

    Full Text Available The technology of displaying message is an important part of communication and advertisement. In recent times, Wireless communication has announced its arrival on big stage and the world is going with Smartphone technology. This work describes the design and implementation of a microcontroller based messaging display system. The messaging display system will be interfaced with an android application which will then be used to display information from the comfort of one‘s phone to an LCD screen using the Bluetooth application interface. The work employs the use of an ATMEGA328p Microcontroller mounted on an Arduino board, a Bluetooth Module (HC-06 and an LCD screen. Most of these electronic display systems were using wired cable connections, the Bluetooth technology used in this work is aimed at solving the problem of wired cable connections.The microcontroller provides all the functionality of the display notices and wireless control. A desired text message from a mobile phone is sent via android mobile application to the Bluetooth module located at the receiving end. The Mobile Application was created using online software called App Inventor. When the entire system was connected and tested, it functioned as designed without any noticeable problems. The Bluetooth module responded to commands being sent from the android application appropriately and in a timely manner. The system was able to display 80 characters on the 4 x 20 LCD within the range of 10m as designated by the Bluetooth datasheet.

    Full Text Available Scientific task for improving the signal-to-noise ratio for user’s voice signal in computer systems and networks during the process of user’s voice authentication is considered. The object of study is the process of input and extraction of the voice signal of authentication system user in computer systems and networks. Methods and means for input and extraction of the voice signal on the background of external interference signals are investigated. Ways for quality improving of the user’s voice signal in systems of voice authentication are investigated experimentally. Firmware means for experimental unit of input and extraction of the user’s voice signal against external interference influence are considered. As modern computer means, including mobile, have two-channel audio card, two microphones are used in the voice signal input. The distance between sonic-wave sensors is 20 mm and it provides forming one direction pattern lobe of microphone array in a desired area of voice signal registration (from 100 Hz to 8 kHz. According to the results of experimental studies, the usage of directional properties of the proposed microphone array and space-time processing of the recorded signals with implementation of constant and adaptive weighting factors has made it possible to reduce considerably the influence of interference signals. The results of firmware experimental studies for input and extraction of the user’s voice signal against external interference influence are shown. The proposed solutions will give the possibility to improve the value of the signal/noise ratio of the useful signals recorded up to 20 dB under the influence of external interference signals in the frequency range from 4 to 8 kHz. The results may be useful to specialists working in the field of voice recognition and speaker discrimination.

  4. The effect of different navigation voices on trust and attention while using in-vehicle navigation systems.

    2014-06-01

    Automobiles are suffused with computers and technology designed to support drivers at all levels of the driving hierarchy. Classic secondary devices, such as in-vehicle navigation systems (IVNS), present strategic and tactical information to drivers. In order to mitigate the potential distraction and workload when interacting with these devices while driving, IVNS often employ voices to deliver navigational instructions. In contrast, voices are used during interpersonal encounters to engage the listener, provide clues about the speaker's personality and make judgments about them, for example, whether to like them and to trust them. A study conducted within a fixed-based medium-fidelity driving simulator investigated if drivers made similar 'personality' attributions to voices emanating from an IVNS and if this subsequently affected how they engaged with the device while driving. Twenty-nine experienced drivers and IVNS users drove to a specified destination with a simulated IVNS and authentically reproduced UK road signage to support their route-finding. Either of two navigation voices were used; one considered 'high-trust' and the other 'low-trust.' Presented with a conflict scenario, where the verbal route guidance differed to the road signs, 22 drivers followed the IVNS instruction rather than the road signs. Of these, the majority were using the 'high-trust' voice. A post-drive questionnaire revealed that, despite the fact that message content and delivery remained equivalent, participants recognized different attributes ('personalities') associated with each of the navigation voices. This influenced their attitudes towards them, including how much they liked them, their preferences for use, and the level of trust that they associated with each voice. While these, so-called, social responses may be invited and indeed encouraged in other contexts, in the automotive domain they are likely to conflict with the intended benefits of using a voice to deliver route

    Full Text Available Abstract These days automotive has turned into a stand out amongst the most well-known modes of transportation on the grounds that a large number of Malaysians could bear to have an auto. There are numerous decisions of innovations in auto that have in the market. One of the engineering is voice controlled framework. Voice Recognition is the procedure of consequently perceiving a certain statement talked by a specific speaker focused around individual data included in discourse waves. This paper is to make an car controlled by voice of human. An essential pre-processing venture in Voice Recognition systems is to recognize the vicinity of noise. Sensitivity to speech variability lacking recognition precision and helplessness to mimic are among the principle specialized obstacles that keep the far reaching selection of speech-based recognition systems. Voice recognition systems work sensibly well with a quiet conditions however inadequately under loud conditions or in twisted channels. The key focus of the project is to control an electric car starter system.

    1974-01-01

    A VOX technique for reducing noise in voice communication systems is described which is based on the separation of voice signals into contiguous frequency-band components with the aid of an adaptive VOX in each band. It is shown that this processing scheme can effectively reduce both wideband and narrowband quasi-periodic noise since the threshold levels readjust themselves to suppress noise that exceeds speech components in each band. Results are reported for tests of the adaptive VOX, and it is noted that improvements can still be made in such areas as the elimination of noise pulses, phoneme reproduction at high-noise levels, and the elimination of distortion introduced by phase delay.

    This paper proposes a novel voice conversion method by frequency warping.The frequency warp-ing function is generated based on mapping formants of the source speaker and the target speaker.In addi-tion to frequency warping,fundamental frequency adjustment,spectral envelope equalization,breathiness addition,and duration modification are also used to improve the similarity to the target speaker.The pro-posed voice conversion method needs only a very small amount of training data for generating the warping function,thereby greatly facilitating its application.Systems based on the proposed method were used for the 2007 TC-STAR intra-lingual voice conversion evaluation for English and Spanish and a cross-lingual voice conversion evaluation for Spanish.The evaluation results show that the proposed method can achieve a much better quality of converted speech than other methods as well as a good balance between quality and similarity.The IBM1 system was ranked No.1 for English evaluation and No.2 for Spanish evaluation.Evaluation results also show that the proposed method is a convenient and competitive method for cross-lingual voice conversion tasks.

    The current middleware for CERN’s Controls System is based on two implementations: CORBA-based Controls MiddleWare (CMW) and Java Messaging Service (JMS). The JMS service is realized using the open source messaging product ActiveMQ and had became an increasing vital part of beam operations as data need to be transported reliably for various areas such as the beam protection system, post mortem analysis, beam commissioning or the alarm system. The current JMS service is made of 18 brokers running either in clusters or as single nodes. The main service is deployed as a two node cluster providing failover and load balancing capabilities for high availability. Non-critical applications running on virtual machines or desktop machines read data via a third broker to decouple the load from the operational main cluster. This scenario has been introduced last year and the statistics showed an uptime of 99.998% and an average data serving rate of 1.6GByte per minute represented by around 150 messages per second.

    Full Text Available Text-based conferencing can be both asynchronous (i.e., participants log into the conference at separate times, and synchronous (i.e., interaction takes place in real time. It is thus subject to the same wide variation as the online audio- and video-conferencing methods (see the earlier Reports in this series. Synchronous text-based approaches (e.g., online chat groups and instant messaging systems are highly popular among online users generally owing to their ability to bring together special-interest groups from around the world without cost. In distance education (DE, however, synchronous chat methods are less widely used, owing in part to the problems of arranging for working adults in different time zones to join a discussion group simultaneously. Instant text messaging is more popular among DE users in view of the choice it provides between responding to a message immediately (synchronous communication or after a delay (asynchronous. The different synchronous and asynchronous approaches are likely to become more widely used in parallel with one another, as they are integrated in individual product packages.

    1999-07-01

    We show how to extract messages masked by a chaotic signal of a time-delay system with very high dimensions and many positive Lyapunov exponents. Using a special embedding coordinate, the infinite-dimensional phase space of the time-delay system is projected onto a special three-dimensional space, which enables us to identify the time delay of the system from the transmitted signal and reconstruct the chaotic dynamics to unmask the hidden message successfully. The message extraction procedure is illustrated by simulations with the Mackey-Glass time-delay system for two types of masking schemes and different kinds of messages.

    Effective overlap of computation and communication is a well understood technique for latency hiding and can yield significant performance gains for applications on high-end computers. In this report, we describe an instrumentation framework developed for message-passing systems to characterize the degree of overlap of communication with computation in the execution of parallel applications. The inability to obtain precise time-stamps for pertinent communication events is a significant problem, and is addressed by generation of minimum and maximum bounds on achieved overlap. The overlap measures can aid application developers and system designers in investigating scalability issues. The approach has been used to instrument two MPI implementations as well as the ARMCI system. The implementation resides entirely within the communication library and thus integrates well with existing approaches that operate outside the library. The utility of the framework is demonstrated by analyzing communication-computation overlap for micro-benchmarks and the NAS benchmarks, and the insights obtained are used to modify the NAS SP benchmark, resulting in improved overlap.

    1987-01-01

    The use of a voice-augmented keyboard input modality is evaluated in a supervisory control application. An implementation of voice recognition technology in supervisory control is proposed: voice is used to request display pages, while the keyboard is used to input system reconfiguration commands. Twenty participants controlled GT-MSOCC, a high-fidelity simulation of the operator interface to a NASA ground control system, via a workstation equipped with either a single keyboard or a voice-augmented keyboard. Experimental results showed that in all cases where significant performance differences occurred, performance with the voice-augmented keyboard modality was inferior to and had greater variance than the keyboard-only modality. These results suggest that current moderately priced voice recognition systems are an inappropriate human-computer interaction technology in supervisory control systems.

    Full Text Available Introduction Research suggests that electronic messaging can improve patient engagement. Studies indicate that a ‘digital divide’ may exist, where certain patient populations may be using electronic messaging less frequently. This study aims to determine which patient characteristics are associated with different levels of usage of an electronic patient-provider messaging system in a diverse urban population.Methods Cross-sectional electronic health record data were extracted for patients 10 years of age or older who live in New York City and who visited a set of clinics between 1 July 2011 and 30 June 2012. Regression analyses determined which participant characteristics were associated with the sending of electronic messages.Results Older, female, English-speaking participants of white race who received more messages, had any diagnoses, more office visits and a provider who sent messages were more likely to send more messages. Non-Millennial, non-white participants who received fewer messages, had more office visits, any diagnoses, a provider who saw fewer patients with patient portal accounts, lived in a low socioeconomic status neighbourhood, and did not have private insurance were more likely to send zero messages.Conclusion This study found significant differences in electronic messaging usage based on demographic, socioeconomic and health-related patient characteristics. Future studies are needed to support these results and determine the causes of observed associations.

    Cutaneous electrogastrogram (EGG) recording offers the benefit of non-invasive gastrointestinal diagnosis. With long-term ambulatory recording of signals, researchers and clinicians could have more opportunities to investigate and analyse paroxysmal or acute symptoms. A portable EGG system based on a digital voice recorder (DVR) is designed for long-term recording of cutaneous EGG signals. The system consists of electrodes, an EGG amplifier, a modulator, and a DVR. Online monitoring and off-line acquisition of EGG are handled by software. A special design employing an integrated timer circuit is used to modulate the EGG frequency to meet the input requirements of the DVR. This approach involves low supply voltage and low power consumption. Software demodulation is used to simplify the complexity of the system, and is helpful in reducing the size of the portable device. By using surface-mount devices (SMD) and a low-power design, the system is robust, compact, and suitable for long-term portable recording. As a result, researchers can record an ambulatory EGG signal by means of the proposed circuits in conjunction with an up-to-date voice-recording device.

    Background The United States Department of Veterans Affairs has implemented an electronic asynchronous “Secure Messaging” tool within a Web-based patient portal (ie, My HealtheVet) to support patient-provider communication. This electronic resource promotes continuous and coordinated patient-centered care, but to date little research has evaluated patients’ experiences and preferences for using Secure Messaging. Objective The objectives of this mixed-methods study were to (1) characterize veterans’ experiences using Secure Messaging in the My HealtheVet portal over a 3-month period, including system usability, (2) identify barriers to and facilitators of use, and (3) describe strategies to support veterans’ use of Secure Messaging. Methods We recruited 33 veterans who had access to and had previously used the portal’s Secure Messaging tool. We used a combination of in-depth interviews, face-to-face user-testing, review of transmitted secure messages between veterans and staff, and telephone interviews three months following initial contact. We assessed participants’ computer and health literacy during initial and follow-up interviews. We used a content-analysis approach to identify dominant themes in the qualitative data. We compared inferences from each of the data sources (interviews, user-testing, and message review) to identify convergent and divergent data trends. Results The majority of veterans (27/33, 82%) reported being satisfied with Secure Messaging at initial interview; satisfaction ratings increased to 97% (31/32, 1 missing) during follow-up interviews. Veterans noted Secure Messaging to be useful for communicating with their primary care team to manage health care needs (eg, health-related questions, test requests and results, medication refills and questions, managing appointments). Four domains emerged from interviews: (1) perceived benefits of using Secure Messaging, (2) barriers to using Secure Messaging, (3) facilitators for using

  11. A social-based cyber-physical system for distributed message transmission

    The explosive increase of the availability of personal mobile devices has brought about a significant amount of peer-to-peer communication opportunities upon their encountering, which can be exploited to realize distributed message transmission among mobile devices. However, the opportunistic encountering among mobile devices, which is determined by the mobility of their holders, has introduced great difficulties on efficiently transmitting a message to its designated destination. Actually, people usually present a certain pattern on daily mobility. Further, device holders often belong to a certain social network community. Therefore, in this paper, we propose a social- based cyber-physical system for distributed message transmission, namely SocMessaging, by integrating both the mobility pattern and the social network of device holders. When selecting an encountered node for message relay, in addition to the node's historical encountering records with the destination node, SocMessaging also considers its social closeness with the destination node. Then, the message is always transmitted to the node that is most likely to meet its destination. As a result, SocMessaging closely connects the cyber world (i.e., network), physical world (i.e., people) and social network (i.e., social connection). Finally, our experimental results demonstrate the efficiency of the proposed system in message transmission between device holders.

    Full Text Available A mobile monitoring system utilizing Bluetooth and mobile messaging services (MMS/SMSs with low-cost hardware equipment is proposed. A proof of concept prototype has been developed and implemented to enable transmission of an Electrocardiogram (ECG signal and body temperature of a patient, which can be expanded to include other vital signs. Communication between a mobile smart-phone and the ECG and temperature acquisition apparatus is implemented using the popular personal area network standard specification Bluetooth. When utilizing MMS for transmission, the mobile phone plots the received ECG signal and displays the temperature using special application software running on the client mobile phone itself, where the plot can be captured and saved as an image before transmission. Alternatively, SMS can be selected as a transmission means, where in this scenario, dedicated application software is required at the receiving device. The experimental setup can be operated for monitoring from anywhere in the globe covered by a cellular network that offers data services.

    Meletiadou, Anastasia; Grimm, Rüdiger

    Many Instant Messaging (IM) systems like Skype or Spark offer ex tended services such as file sharing, VoIP, or a shared whiteboard. As the name suggests, IM applications are predominantly used for spontaneous text-based communication for private or business purposes. In this paper we explore their potential to serve as platforms for secure collaborative applications like electronic contract negotiation, e-payment or electronic voting. Such applications have to deal with challenges like time constraints (“instant” com munication is desired), integration of media channels and the absence of one uni fying “sphere of control” covering all participants. In this paper, we address these challenges by discussing one particular secure collaborative application: secure decision processes for small groups. We provide the following contribu tions: (1) we define three varying scenarios and corresponding security require ments (2) we present an IM-based architecture implementing these scenarios, in cluding a Video-based authentication mechanism, and (3) we discuss poten tial attack patterns.

    Bundrock, Tony; Wilkinson, Mal

    1990-01-01

    The evaluation procedure to choose a low bit rate voice coding algorithm is described for the Australian land mobile satellite system. The procedure is designed to assess both the inherent quality of the codec under 'normal' conditions and its robustness under 'severe' conditions. For the assessment, normal conditions were chosen to be random bit error rate with added background acoustic noise and the severe condition is designed to represent burst error conditions when mobile satellite channel suffers from signal fading due to roadside vegetation. The assessment is divided into two phases. First, a reduced set of conditions is used to determine a short list of candidate codecs for more extensive testing in the second phase. The first phase conditions include quality and robustness and codecs are ranked with a 60:40 weighting on the two. Second, the short listed codecs are assessed over a range of input voice levels, BERs, background noise conditions, and burst error distributions. Assessment is by subjective rating on a five level opinion scale and all results are then used to derive a weighted Mean Opinion Score using appropriate weights for each of the test conditions.

    The ATLAS Trigger and Data Acquisition (TDAQ) is a large distributed computing system composed of several thousands of interconnected computers and tens of thousands applications. During a run, TDAQ applications produce a lot of control and information messages with variable rates, addressed to TDAQ operators or to other applications. Reliable, fast and accurate delivery of the messages is important for the functioning of the whole TDAQ system. The Message Transport Service (MTS) provides facilities for the reliable transport, the filtering and the routing of the messages, basing on publish-subscribe-notify communication pattern with content-based message filtering. During the ongoing LHC shutdown, the MTS was re-implemented, taking into account important requirements like reliability, scalability and performance, handling of slow subscribers case and also simplicity of the design and the implementation. MTS uses CORBA middleware, a common layer for TDAQ infrastructure, and provides sending/subscribing APIs i...

    Li, Alex Ning; Liao, Hui; Tangirala, Subrahmaniam; Firth, Brady M

    2017-08-01

    We propose that it is important to take the content of team voice into account when examining its impact on team processes and outcomes. Drawing on regulatory focus theory (Higgins, 1997), we argue that promotive team voice and prohibitive team voice help teams achieve distinct collective outcomes-that is, team productivity performance gains and team safety performance gains, respectively. Further, we identify mechanisms through which promotive and prohibitive team voices uniquely influence team outcomes as well as boundary conditions for such influences. In data collected from 88 production teams, we found that promotive team voice had a positive association with team productivity performance gains. By contrast, prohibitive team voice had a positive association with team safety performance gains. The relationship between promotive team voice and team productivity performance gains was mediated by team innovation, and the relationship between prohibitive team voice and team safety performance gains was mediated by team monitoring. In addition, the indirect effect of prohibitive team voice on team safety performance gains via team monitoring was stronger when prior team safety performance was lower. We discuss the theoretical and practical implications of these findings. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  7. Multiparty Quantum Secret Sharing of Classical Message using Cavity Quantum Electrodynamic System

    Institute of Scientific and Technical Information of China (English)

    HAN Lian-Fang; LIU Yi-Min; ZHANG Zhan-Jun

    2006-01-01

    @@ An experimental feasible scheme of multiparty secret sharing of classical messages is proposed, based on a cavity quantum electrodynamic system. The secret messages are imposed on atomic Bell states initially in the sender's possession by local unitary operations. By swapping quantum entanglement of atomic Bell states, the secret messages are split into several parts and each part is distributed to a separate party. In this case, any subset of the entire party group can not read out the secret message but the entirety via mutual cooperations. In this scheme, to discriminate atomic Bell states, additional classical fields are employed besides the same highly-detuned single-mode cavities used to prepare atomic Bell states. This scheme is insensitive to the cavity decay and the thermal field, and usual joint Bell-state measurements are unnecessary.

  8. Propositional Dynamic Logic for Message-Passing Systems

    Bollig, Benedikt; Meinecke, Ingmar

    2010-01-01

    We examine a bidirectional propositional dynamic logic (PDL) for finite and infinite message sequence charts (MSCs) extending LTL and TLC$^{-}$. By this kind of multi-modal logic we can express properties both in the entire future and in the past of an event. Path expressions strengthen the classical until operator of temporal logic. For every formula defining an MSC language, we construct a communicating finite-state machine (CFM) accepting the same language. The CFM obtained has size exponential in the size of the formula. This synthesis problem is solved in full generality, i.e., also for MSCs with unbounded channels. The model checking problem for CFMs and HMSCs turns out to be in PSPACE for existentially bounded MSCs. Finally, we show that, for PDL with intersection, the semantics of a formula cannot be captured by a CFM anymore.

    A method for passing remote messages in a parallel computer system formed as a network of interconnected compute nodes includes that a first compute node (A) sends a single remote message to a remote second compute node (B) in order to control the remote second compute node (B) to send at least one remote message. The method includes various steps including controlling a DMA engine at first compute node (A) to prepare the single remote message to include a first message descriptor and at least one remote message descriptor for controlling the remote second compute node (B) to send at least one remote message, including putting the first message descriptor into an injection FIFO at the first compute node (A) and sending the single remote message and the at least one remote message descriptor to the second compute node (B).

    One purpose of integrating voice interfaces into embedded vehicle systems is to reduce drivers' visual and manual distractions with 'infotainment' technologies. However, there is scant research on actual benefits in production vehicles or how different interface designs affect attentional demands. Driving performance, visual engagement, and indices of workload (heart rate, skin conductance, subjective ratings) were assessed in 80 drivers randomly assigned to drive a 2013 Chevrolet Equinox or Volvo XC60. The Chevrolet MyLink system allowed completing tasks with one voice command, while the Volvo Sensus required multiple commands to navigate the menu structure. When calling a phone contact, both voice systems reduced visual demand relative to the visual-manual interfaces, with reductions for drivers in the Equinox being greater. The Equinox 'one-shot' voice command showed advantages during contact calling but had significantly higher error rates than Sensus during destination address entry. For both secondary tasks, neither voice interface entirely eliminated visual demand. Practitioner Summary: The findings reinforce the observation that most, if not all, automotive auditory-vocal interfaces are multi-modal interfaces in which the full range of potential demands (auditory, vocal, visual, manipulative, cognitive, tactile, etc.) need to be considered in developing optimal implementations and evaluating drivers' interaction with the systems. Social Media: In-vehicle voice-interfaces can reduce visual demand but do not eliminate it and all types of demand need to be taken into account in a comprehensive evaluation.

    Design and develop a mobile messaging system called mSalUV, which reminds patients with type 2 diabetes about taking their medication and attending appointments and promotes healthy lifestyles, and explore patient opinion regarding use of the system. The study had three stages: 1) design and development of mSalUV; 2) design and development of text messages; and 3) exploration of patient opinion regarding use of mSalUV. The mSalUV system was created and around 40 text messages were designed. A total of 1 850 messages were sent during the 45 day intervention. Patients thought that mSalUV helped them to treat their disease and that it was easy to use, they were inclined to continue using the system in the future, and people close to them (family members and support networks) supported them using it. Furthermore, they perceived the system as "someone that cared about them." The results suggest that a system such as mSalUV would be well accepted by its potential users; in this case, people with type 2 diabetes. This presents a very interesting scenario that will enable taking advantage of new technologies for health. Further research is needed to evaluate the system's efficiency and effectiveness.

    The faculty of language depends on the interplay between the production and perception of speech sounds. A relevant open question is whether the dimensions that organize voice perception in the brain are acoustical or depend on properties of the vocal system that produced it. One of the main empirical difficulties in answering this question is to generate sounds that vary along a continuum according to the anatomical properties the vocal apparatus that produced them. Here we use a mathematical model that offers the unique possibility of synthesizing vocal sounds by controlling a small set of anatomically based parameters. In a first stage the quality of the synthetic voice was evaluated. Using specific time traces for sub-glottal pressure and tension of the vocal folds, the synthetic voices generated perceptual responses, which are indistinguishable from those of real speech. The synthesizer was then used to investigate how the auditory cortex responds to the perception of voice depending on the anatomy of the vocal apparatus. Our fMRI results show that sounds are perceived as human vocalizations when produced by a vocal system that follows a simple relationship between the size of the vocal folds and the vocal tract. We found that these anatomical parameters encode the perceptual vocal identity (male, female, child) and show that the brain areas that respond to human speech also encode vocal identity. On the basis of these results, we propose that this low-dimensional model of the vocal system is capable of generating realistic voices and represents a novel tool to explore the voice perception with a precise control of the anatomical variables that generate speech. Furthermore, the model provides an explanation of how auditory cortices encode voices in terms of the anatomical parameters of the vocal system.

    Current mechanical key in the motorcycle is prone to bulgary, being stolen or misplaced. Intelligent biometric voice recognition as means to replace this mechanism is proposed as an alternative. The proposed system will decide whether the voice is belong to the user or not and the word utter by the user is ‘On’ or ‘Off’. The decision voice will be sent to Arduino in order to start or stop the engine. The recorded voice is processed in order to get some features which later be used as input to the proposed system. The Mel-Frequency Ceptral Coefficient (MFCC) is adopted as a feature extraction technique. The extracted feature is the used as input to the SVM-based identifier. Experimental results confirm the effectiveness of the proposed intelligent voice recognition and word recognition system. It show that the proposed method produces a good training and testing accuracy, 99.31% and 99.43%, respectively. Moreover, the proposed system shows the performance of false rejection rate (FRR) and false acceptance rate (FAR) accuracy of 0.18% and 17.58%, respectively. In the intelligent word recognition shows that the training and testing accuracy are 100% and 96.3%, respectively.

    2000-06-07

    The sound-producing structure in birds is the syrinx, which is usually a two-part organ located at the junction of the bronchi. As each branch of the syrinx produces sound independently, many birds have two acoustic sources. Thirty years ago, we had anatomical, physiological and acoustical evidence of this two-voice phenomenon but no function was known. In songbirds, often these two voices with their respective harmonics are not activated simultaneously but they are obvious in large penguins and generate a beat pattern which varies between individuals. The emperor penguin breeds during the Antarctic winter, incubating and carrying its egg on its feet. Without the topographical cue of a nest, birds identify each other only by vocal means when switching duties during incubation or chick rearing. To test whether the two-voice system contains the identity code, we played back the modified call of their mate to both adults and also the modified call of their parents to chicks. Both the adults and the chicks replied to controls (two voices) but not to modified signals (one voice being experimentally suppressed). Our experiments demonstrate that the beat generated by the interaction of these two fundamental frequencies conveys information about individual identity and also propagates well through obstacles, being robust to sound degradation through the medium of bodies in a penguin colony. The two-voice structure is also clear in the call of other birds such as the king penguin, another non-nesting species, but not in the 14 other nesting penguins. We concluded that the two-voice phenomenon functions as an individual recognition system in species using few if any landmarks to meet. In penguins, this coding process, increasing the call complexity and resisting sound degradation, has evolved in parallel with the loss of territoriality.

    Although cochlear implants are primarily auditory prostheses, they have also demonstrated their usefulness as aids to speech production and the acquisition of spoken language in children. This presentation reports on research currently being conducted at the Indiana University Medical Center on the development of phonological systems by children with five or more years of cochlear implant use in English-speaking environments. Characteristics of the feature [voice] will be examined in children with cochlear implants and in two comparison groups: adults with normal hearing and children with normal hearing. Specific aspects of voicing to be discussed include characteristic error patterns, phonetic implementation of the voicing contrast, and phonetic implementation of neutralization of the voicing contrast. Much of the evidence obtained thus far indicates that voicing acquisition in children with cochlear implants is not radically different from that of children with normal hearing. Many differences between the systems of children with cochlear implants and the ambient system thus appear to reflect the children's age as much as their hearing status.

    Simpson, C. A.; Williams, D. H.

    1980-01-01

    Some handbooks and human factors design guides have recommended that a voice warning should be preceded by a tone to attract attention to the warning. As far as can be determined from a search of the literature, no experimental evidence supporting this exists. A fixed-base simulator flown by airline pilots was used to test the hypothesis that the total 'system-time' to respond to a synthesized voice cockpit warning would be longer when the message was preceded by a tone because the voice itself was expected to perform both the alerting and the information transfer functions. The simulation included realistic ATC radio voice communications, synthesized engine noise, cockpit conversation, and realistic flight routes. The effect of a tone before a voice warning was to lengthen response time; that is, responses were slower with an alerting tone. Lengthening the voice warning with another work, however, did not increase response time.

    Effective overlap of computation and communication is a well understood technique for latency hiding and can yield significant performance gains for applications on high-end computers. In this report, we describe an instrumentation framework developed for messagepassing systems to characterize the degree of overlap of communication with computation in the execution of parallel applications. The inability to obtain precise time-stamps for pertinent communication events is a significant problem, and is addressed by generation of minimum and maximum bounds on achieved overlap. The overlap measures can aid application developers and system designers in investigating scalability issues. The approach has been used to instrument two MPI implementations as well as the ARMCI system. The implementation resides entirely within the communication library and thus integrates well with existing approaches that operate outside the library. The utility of the framework is demonstrated by analyzing communication-computation overlap for micro-benchmarks and the NAS benchmarks, and the insights obtained are used to modify the NAS SP benchmark, resulting in improved overlap.

    The ATLAS Distributed Data Management system is composed of semi-autonomous, heterogeneous, and independently designed subsystems. To achieve successful operation of such a system, the activities of the agents controlling the subsystems have to be coordinated. In addition, external applications can require to synchronize on events relative to data availability. A common way to proceed is to implement polling strategies within the distributed components, which leads to an increase of the load in the overall system. We describe an alternative based on notifications using standard message queuing. The application of this technology in the distributed system has been exercised.

    2000-06-01

    We examined the communication process in a situation typical of the nursing setting by use of a double-bind communication. Our objective was to examine which of two cues in communications from a patient, tone of voice or verbal content, was more important in judging the speaker's emotional status and personality traits and in arousing the listening nurse's emotions. Subjects were 82 nurses who worked at the university hospital and 100 students who were studying at the Faculty of Nursing of the university. They were assigned into four groups at random, presented professionally tape-recorded scripts representing a patient's verbal report, and then completed a questionnaire concerning the speaker's emotional status as well as the listener's own emotional status. When the listeners judged the speaker's emotional status, they gave more attention to a negative emotional expression, and when the listeners formed an impression of the speaker's personality traits, they were influenced by the speaker's tone of voice rather than by the content of the speech.

    Subcortical brain structures of the limbic system, such as the amygdala, are thought to decode the emotional value of sensory information. Recent neuroimaging studies, as well as lesion studies in patients, have shown that the amygdala is sensitive to emotions in voice and music. Similarly, the hippocampus, another part of the temporal limbic system (TLS), is responsive to vocal and musical emotions, but its specific roles in emotional processing from music and especially from voices have been largely neglected. Here we review recent research on vocal and musical emotions, and outline commonalities and differences in the neural processing of emotions in the TLS in terms of emotional valence, emotional intensity and arousal, as well as in terms of acoustic and structural features of voices and music. We summarize the findings in a neural framework including several subcortical and cortical functional pathways between the auditory system and the TLS. This framework proposes that some vocal expressions might already receive a fast emotional evaluation via a subcortical pathway to the amygdala, whereas cortical pathways to the TLS are thought to be equally used for vocal and musical emotions. While the amygdala might be specifically involved in a coarse decoding of the emotional value of voices and music, the hippocampus might process more complex vocal and musical emotions, and might have an important role especially for the decoding of musical emotions by providing memory-based and contextual associations.

    Full Text Available High-performance reconfigurable computers (HPRCs provide a mix of standard processors and FPGAs to collectively accelerate applications. This introduces new design challenges, such as the need for portable programming models across HPRCs and system-level verification tools. To address the need for cosimulating a complete heterogeneous application using both software and hardware in an HPRC, we have created a tool called the Message-passing Simulation Framework (MSF. We have used it to simulate and develop an interface enabling an MPI-based approach to exchange data between X86 processors and hardware engines inside FPGAs. The MSF can also be used as an application development tool that enables multiple FPGAs in simulation to exchange messages amongst themselves and with X86 processors. As an example, we simulate a LINPACK benchmark hardware core using an Intel-FSB-Xilinx-FPGA platform to quickly prototype the hardware, to test the communications. and to verify the benchmark results.

    2011-01-01

    Despite the increasing maturity of model-driven software development (MDD), some research challenges remain open in the field of information systems (IS). For instance, there is a need to improve modelling techniques so that they cover several development stages in an integrated way, and they facilitate the transition from analysis to design. This paper presents Message Structures, a technique for the specification of communicative interactions between the IS and organisational actors. This technique can be used both in the analysis stage and in the design stage. During analysis, it allows abstracting from the technology that will support the IS, and to complement business process diagramming techniques with the specification of the communicational needs of the organisation. During design, Message Structures serves two purposes: (i) it allows to systematically derive a specification of the IS memory (e.g. a UML class diagram), (ii) and it allows to reason the user interface design using abstract patterns.

    To avoid missing events associated with clinical activity, the authors previously developed a novel, web-based, self-reporting Crohn disease (CD) symptom diary. However, although this diary provided a means of self-checking based on responses to set questions based on Harvey-Bradshaw index scores, it was limited in terms of describing other specific symptoms. Thus, the authors added a space to the questionnaire, which allows patients to send clinicians questions or a description of unpredictable events. The aim of the present study was to assess the clinical usefulness of this messaging system by analyzing patients' messages.The messaging system between patients and their doctors was included in a webpage created for recording patients' symptom diaries (www.cdsd.or.kr). Using this system, patients can send messages easily at any time and doctors can read and respond to these messages immediately using a smart phone or computer. In the present study, the authors retrospectively reviewed 686 messages sent by 152 patients from July 2012 to July 2014 and patient medical records.Mean patient age was 29.0 ± 11.6 years and the male-to-female ratio was 99:53. Most messages regarded symptoms (381 messages, 55.5%), which was followed by self-reports about general condition (195 messages, 28.4%) and questions about treatment (71 messages, 10.3%). With respect to symptoms, abdominal pain was most common (145 cases, 21.1%) followed by hematochezia (36 cases, 5.2%). Problems about medication were the most frequently associated with treatment (65, 91.5%). Patients above 40 years showed a greater tendency to focus on symptoms and treatment (P = 0.025). The doctor answer rate was 56.3% (n = 386), and based on these responses, an early visit was needed in 28 cases (7.3%).Using this web-based messaging system, patients were able to obtain proper advice from their physicians without visiting clinics or searching the Internet, and in addition, 7.3% of messages prompted an early

    2016-11-08

    Outside health care, content tailoring is driven algorithmically using machine learning compared to the rule-based approach used in current implementations of computer-tailored health communication (CTHC) systems. A special class of machine learning systems ("recommender systems") are used to select messages by combining the collective intelligence of their users (ie, the observed and inferred preferences of users as they interact with the system) and their user profiles. However, this approach has not been adequately tested for CTHC. Our aim was to compare, in a randomized experiment, a standard, evidence-based, rule-based CTHC (standard CTHC) to a novel machine learning CTHC: Patient Experience Recommender System for Persuasive Communication Tailoring (PERSPeCT). We hypothesized that PERSPeCT will select messages of higher influence than our standard CTHC system. This standard CTHC was proven effective in motivating smoking cessation in a prior randomized trial of 900 smokers (OR 1.70, 95% CI 1.03-2.81). PERSPeCT is an innovative hybrid machine learning recommender system that selects and sends motivational messages using algorithms that learn from message ratings from 846 previous participants (explicit feedback), and the prior explicit ratings of each individual participant. Current smokers (N=120) aged 18 years or older, English speaking, with Internet access were eligible to participate. These smokers were randomized to receive either PERSPeCT (intervention, n=74) or standard CTHC tailored messages (n=46). The study was conducted between October 2014 and January 2015. By randomization, we compared daily message ratings (mean of smoker ratings each day). At 30 days, we assessed the intervention's perceived influence, 30-day cessation, and changes in readiness to quit from baseline. The proportion of days when smokers agreed/strongly agreed (daily rating ≥4) that the messages influenced them to quit was significantly higher for PERSPeCT (73%, 23/30) than

  15. Semantic Model for Voice Controlled Telephone Dialing and Inquiry Systems

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A new scheme is presented to detect a large number of keywords in voice controlled switchboard tasks. The new scheme is based on two stages. In the first stage, N-best syllable candidates with their corresponding acoustic scores are generated by an acoustic recognizer. In the second stage, a semantic model based parser is applied to determine the optimum keywords by searching through the lattice of N-best candidates. The experimental results show that when the spoken input deviates from the predefined syntactic constraints, the parser can also demonstrate high performance. For comparison purposes, the most common way to incorporate the syntactic knowledge of the task directly into the acoustic recognizer in the form of a finite state network is also investigated. Furthermore, to address the sparse-data problems, out-of-domain data in the form of newspaper text are used to obtain a more robust combined semantic model. The experiments show that the combined semantic model can improve the keywords detection rate from 90.07% to 92.91% when 80 ungrammatical sentences which do not conform to the task grammar are used as testing material.

The Texas Instruments OMAP-L138 is integrated in order to enhance the quality of speech signal by reducing noise and connected with the wheelchair for processing of the voice signal. The Hawkboard denoises speech signal and HMC2007 recognizes the commnads. It also generates different desired signals according to the spoken words which further used to control the movement of wheelchair, a vector of information on the context given by a set of sensors for security actions. Six words are recognized which are start, forward, reverse, left, right, stop. In order to gain in time design, experiments have shown that the best way is to choose a speech recognition kit and to adapt it to the application. The result at the end show the efficiency of the system.

    Full Text Available Abstract Background One-half of patients with cancer have pain. In nearly one out of two cancer patients with pain, this was undertreated. Inadequate pain control still remains an important problem in this group of patients. Therefore, in 2008 a national, evidence-based multidisciplinary clinical practice guideline 'pain in patients with cancer' has been developed. Yet, publishing a guideline is not enough. Implementation is needed to improve pain management. An innovative implementation strategy, Short Message Service with Interactive Voice Response (SVS-IVR, has been developed and pilot tested. This study aims to evaluate on effectiveness of this strategy to improve pain reporting, pain measurement and adequate pain therapy. In addition, whether the active role of the patient and involvement of caregivers in pain management may change. Methods/design A cluster randomised controlled trial with two arms will be performed in six oncology outpatient clinics of hospitals in the Southeastern region of the Netherlands, with three hospitals in the intervention and three in the control condition. Follow-up measurements will be conducted in all hospitals to study the long-term effect of the intervention. The intervention includes training of professionals (medical oncologists, nurses, and general practitioners and SMS-IVR to report pain in patients with cancer to improve pain reporting by patients, pain management by medical oncologists, nurses, and general practitioners, and decrease pain intensity. Discussion This innovative implementation strategy with technical tools and the involvement of patients, may enhance the use of the guideline 'pain in patients with cancer' for pain management. Short Message Service alerts may serve as a tool to support self-management of patients. Therefore, the SMS-IVR intervention may increase the feeling of having control over one's life.

    Patients want to be able to communicate with their physicians by e-mail. However, physicians are often concerned about the impact that such communications will have on their time, productivity, and reimbursement. Typically, physicians are not reimbursed for time spent communicating with patients electronically. But under federal meaningful-use criteria for information technology, physicians can receive a modest incentive for such communications. Little is known about trends in secure e-mail messaging between physicians and patients. To understand these trends, we analyzed the volume of messages in a large academic health system's patient portal in the period 2001-10. At the end of 2010, 49,778 patients (22.7 percent of all patients seen within the system) had enrolled in the portal, and 36.9 percent of enrolled patients (8.4 percent of all patients) had sent at least one message to a physician. Physicians in the aggregate saw a near tripling of e-mail messages during the study period. However, the number of messages per hundred patients per month stabilized between 2005 and 2010, at an average of 18.9 messages. As physician reimbursement moves toward global payments, physicians' and patients' participation in secure messaging will likely increase, and electronic communication should be considered part of physicians' job descriptions.

    Interactive voice response (IVR) is increasingly used to monitor and promote medication adherence. In 2014, we evaluated patient acceptability toward IVR as part of the ENRICH Study, aimed to enhance adherence to isoniazid preventive therapy for tuberculosis prevention among HIV-positive adults in Ethiopia. Qualitative interviews were completed with 30 participants exposed to 2867 IVR calls, of which 24 % were completely answered. Individualized IVR options, treatment education, and time and cost savings facilitated IVR utilization, whereas poor IVR instruction, network and power malfunctions, one-way communication with providers, and delayed clinic follow-up inhibited utilization. IVR acceptability was complicated by HIV confidentiality, mobile phone access and literacy, and patient-provider trust. Incomplete calls likely reminded patients to take medication but were less likely to capture adherence or side effect data. Simple, automated systems that deliver health messages and triage clinic visits appear to be acceptable in this resource-limited setting.

    This was an applied investigation examining the ability of a speech recognition system to recognize speakers' inputs when the speakers were under different stress levels. Subjects were asked to speak to a voice recognition system under three conditions: (1) normal office environment, (2) emotional stress, and (3) perceptual-motor stress. Results indicate a definite relationship between voice recognition system performance and the type of low stress reference patterns used to achieve recognition.

    Excellent results have been reported with the use of voice prostheses for the rehabilitation of laryngectomees. Patients, however, consider it a disadvantage that the tracheostoma must be closed manually for speech production. This limits their ability to simultaneously communicate by gesture or to work with both hands. An automatic tracheostoma valve helps patients overcome this problem. We describe a prospective clinical trial evaluating our experience with the Provox FreeHands HME Automatic Tracheostoma Valve system. Twenty-four laryngectomees were randomly selected from the patients who had undergone laryngectomy at the ENT Department. Immediately, after 4 weeks and 6 months later having been fitted with a Provox FreeHands HME, the patients were asked to complete a questionnaire in order to assess their satisfaction, voice quality, wearing comfort, fixation, potential problems, and the effectiveness of the HME cassette. In addition, we investigated relevant voice quality parameters including dynamics range, frequency range of the speaking voice, and maximum phonation time. Seven patients discontinued the study due to problems of securing the valve to the skin (four patients) or recurrent cancer (three patients). Ten of the remaining 17 patients wore the valve daily for an average of 8.4 h. A total of 88% of the patients considered it a great advantage to be able to speak without having to use their hands. With the Provox FreeHands HME, maximum phonation time was 8.7 (+/-6.2) s and the dynamic range was 21.9 (+/-5.8) decibels. The results show that the Provox FreeHands HME Automatic Tracheostoma Valve system not only allows hands-free speech but is also associated with excellent compliance and good voice rehabilitation.

    More and more linear servo systems have been used in servo applications. Direct drive technology can greatly increase the bandwidth and the tracking accuracy. A position servo-system based on linear voice-coil motor was designed for one linear oscillation movement application. Besides the conventional position, speed and current control loops, the speed and acceleration feed-forward control of command position signal were also used. The experimental test proved the correctness of the design, and the system can track the given periodic sinnsoid position command signal of 15Hz with high accuracy. The linear voice-coil motor is very suitable for short stroke position tracking application with high dynamic response.

    The purpose of this study was to verify the effect of pop-up messages (regarding a history of dual-energy X-ray absorptiometry [DXA]) on the identification and management of osteoporosis after osteoporotic hip or spine fractures. We hypothesized that these pop-up messages would increase the awareness and management of osteoporosis among clinicians and patients. We introduced pop-up messages regarding a history of DXA in our Order Communication System (March 2012) and evaluated the records of 404 patients who were treated between January 2011 and December 2012. The patients were categorized as being treated without the pop-up messages (Group I, before March 2012) or with the pop-up messages (Group II, after March 2012). We compared their rates of DXA prescription, osteoporosis medication, exercise, mortality and subsequent refractures during a 2-year follow-up. After introducing the pop-up messages, the DXA prescription rate increased from 35.1 to 57.1% (P pop-up messages positively affected the behaviours of orthopaedic surgeons and were associated with increased rates of prescription of DXA, osteoporosis medication, and might affect the behaviour of patient, increased exercise rate. Therefore, we recommend using this simple and effective method to improve physicians' awareness of osteoporosis. © 2016 John Wiley & Sons, Ltd.

    Due to limited crew availability to support science and the large number of experiments to be operated simultaneously, telescience is key to a successful International Space Station (ISS) science program. Crew, operations personnel at NASA centers, and researchers at universities and companies around the world must work closely together to per orm scientific experiments on-board ISS. The deployment of reliable high-speed Internet Protocol (IP)-based networks promises to greatly enhance telescience capabilities. These networks are now being used to cost-effectively extend the reach of remote mission support systems. They reduce the need for dedicated leased lines and travel while improving distributed workgroup collaboration capabilities. NASA has initiated use of Voice over Internet Protocol (VoIP) to supplement the existing mission voice communications system used by researchers at their remote sites. The Internet Voice Distribution System (IVoDS) connects remote researchers to mission support "loopsll or conferences via NASA networks and Internet 2. Researchers use NODS software on personal computers to talk with operations personnel at NASA centers. IVoDS also has the ;capability, if authorized, to allow researchers to communicate with the ISS crew during experiment operations. NODS was developed by Marshall Space Flight Center with contractors & Technology, First Virtual Communications, Lockheed-Martin, and VoIP Group. NODS is currently undergoing field-testing with full deployment for up to 50 simultaneous users expected in 2002. Research is being performed in parallel with IVoDS deployment for a next-generation system to qualitatively enhance communications among ISS operations personnel. In addition to the current voice capability, video and data/application-sharing capabilities are being investigated. IVoDS technology is also being considered for mission support systems for programs such as Space Launch Initiative and Homeland Defense.

    2010-01-01

    Full Text Available An improved self-organizing map (SOM, parameterless-growing-SOM (PL-G-SOM, is proposed in this paper. To overcome problems existed in traditional SOM (Kohonen, 1982, kinds of structure-growing-SOMs or parameter-adjusting-SOMs have been invented and usually separately. Here, we combine the idea of growing SOMs (Bauer and Villmann, 1997; Dittenbach et al. 2000 and a parameterless SOM (Berglund and Sitte, 2006 together to be a novel SOM named PL-G-SOM to realize additional learning, optimal neighborhood preservation, and automatic tuning of parameters. The improved SOM is applied to construct a voice instruction learning system for partner robots adopting a simple reinforcement learning algorithm. User's instructions of voices are classified by the PL-G-SOM at first, then robots choose an expected action according to a stochastic policy. The policy is adjusted by the reward/punishment given by the user of the robot. A feeling map is also designed to express learning degrees of voice instructions. Learning and additional learning experiments used instructions in multiple languages including Japanese, English, Chinese, and Malaysian confirmed the effectiveness of our proposed system.

    Abstract Problem Polio remains endemic in many areas of Pakistan, including large urban centres such as Karachi. Approach During each of seven supplementary immunization activities against polio in Karachi, mobile phone numbers of the caregivers of a random sample of eligible children were obtained. A computer-based system was developed to send two questions – as short message service (SMS) texts – automatically to each number after the immunization activity: “Did the vaccinator visit your house?” and “Did the enrolled child in your household receive oral polio vaccine?” Persistent non-responders were phoned directly by an investigator. Local setting A cluster sampling technique was used to select representative samples of the caregivers of young children in Karachi in general and of such caregivers in three of the six “high-risk” districts of the city where polio cases were detected in 2011. Relevant changes In most of the supplementary immunization activities investigated, vaccine coverages estimated using the SMS system were very similar to those estimated by interviewing by phone those caregivers who never responded to the SMS messages. In the high-risk districts investigated, coverages estimated using the SMS system were also similar to those recorded – using lot quality assurance sampling – by the World Health Organization. Lessons learnt For the monitoring of coverage in supplementary immunization activities, automated SMS-based systems appear to be an attractive and relatively inexpensive option. Further research is needed to determine if coverage data collected by SMS-based systems provide estimates that are sufficiently accurate. Such systems may be useful in other large-scale immunization campaigns. PMID:24700982

  13. Efficient Messaging through Cluster Coordinators in Decentralized Controlled Material Flow Systems

    Directory of Open Access Journals (Sweden)

    Lieberoth-Leden Christian

    2016-01-01

    Full Text Available The modularization of the hard- and software is one approach handling the demand for increasing flexibility and changeability of automated material flow systems. A control that is distributed across several different hardware controllers leads to a great demand for coordination between the modules while planning for example transports, especially if there is a mutual dependency between the modules on the executing tasks. Short-term changes in planning often initiate a rescheduling chain reaction, which causes a high communication load in the system. In the presented approach, module clusters with a centralized coordinator are automatically formed out of multiple modules and substitutional take over the surrounding communication for the modules. As a result, they minimize exchanged messages by focusing on the essential information.

    2011-01-01

    This article examines the inspiration, construction, and meaning of the Bellevue Classification System (BCS), created during the 1930s for use in the Bellevue School of Nursing Library. Nursing instructor Ann Doyle, with assistance from librarian Mary Casamajor, designed the BCS after consulting with library leaders and examining leading contemporary classification systems, including the Dewey Decimal Classification and Library of Congress, Ballard, and National Health Library classification systems. A close textual reading of the classes, subclasses, and subdivisions of these classification systems against those of the resulting BCS, reveals Doyle's belief that the BCS was created not only to organize the literature, but also to promote the burgeoning intellectualism and professionalism of early twentieth-century American nursing.

    Application development for high-performance distributed computing systems, or computational grids as they are sometimes called, requires grid-enabled tools that hide mundate aspects of the heterogeneous grid environment without compromising performance. As part of an investigation of these issues, they have developed MPICH-G, a grid-enabled implementation of the Message Passing Interface (MPI) that allows a user to run MPI programs across multiple computers at different sites using the same commands that would be used on a parallel computer. This library extends the Argonne MPICH implementation of MPI to use services provided by the globus grid toolkit. In this paper, they describe the MPICH-G implementation and present preliminary performance results.

    2000-01-01

    Full Text Available This paper describes an intelligent multimedia tutoring system for the passive voice of the English grammar. The system may be used to present theoretical issues about the passive voice and to provide exercises that the student may solve. The main focus of the tutor is on the student's error diagnosis process, which is performed by the student modelling component. When the student types the solution to an exercise, the system examines the correctness of the answer. If the student's answer has been erroneous it attempts to diagnose the underlying misconception of the mistake. In order to provide individualised help, the system holds a profile for every student, the long term student model. The student’s progress and his/her usual mistakes are recorded to this long term student model. This kind of information is used for the individualised error diagnosis of the student in subsequent sessions. In addition, the information stored about the student can also be used for the resolution of an arising ambiguity, as to what the underlying cause of a student error has been.

The practical application of Genetic Algorithm (GA to the solution of engineering problem is a rapidly emerging approach in the field of control engineering and signal processing. Genetic algorithms are useful for searching a space in multi-directional way from large spaces and poorly defined space. Voice is a signal of infinite information. Digital processing of voice signal is very important for automatic voice recognition technology. Nowadays, voice processing is very much important in security mechanism due to mimicry characteristic. So studying the voice feature extraction in voice processing is very necessary in military, hospital, telephone system, investigation bureau and etc. In order to extract valuable information from the voice signal, make decisions on the process, and obtain results, the data needs to be manipulated and analyzed. In this paper, if the instant voice is not matched with same person’s reference voices in the database, then Genetic Algorithm (GA is applied between two randomly chosen reference voices. Again the instant voice is compared with the result of Genetic Algorithm (GA which is used, including its three main steps: selection, crossover and mutation. We illustrate our approach with different sample of voices from human in our institution.

    The present invention is a system and method for characterizing human (or animate) speech voiced excitation functions and acoustic signals, for removing unwanted acoustic noise which often occurs when a speaker uses a microphone in common environments, and for synthesizing personalized or modified human (or other animate) speech upon command from a controller. A low power EM sensor is used to detect the motions of windpipe tissues in the glottal region of the human speech system before, during, and after voiced speech is produced by a user. From these tissue motion measurements, a voiced excitation function can be derived. Further, the excitation function provides speech production information to enhance noise removal from human speech and it enables accurate transfer functions of speech to be obtained. Previously stored excitation and transfer functions can be used for synthesizing personalized or modified human speech. Configurations of EM sensor and acoustic microphone systems are described to enhance noise cancellation and to enable multiple articulator measurements.

    The process of learning and understand the sign language may be cumbersome to some, and therefore, this paper proposes a solution to this problem by providing a voice (English Language) to sign language translation system using Speech and Image processing technique. Speech processing which includes Speech Recognition is the study of recognizing the words being spoken, regardless of whom the speaker is. This project uses template-based recognition as the main approach in which the V2S system first needs to be trained with speech pattern based on some generic spectral parameter set. These spectral parameter set will then be stored as template in a database. The system will perform the recognition process through matching the parameter set of the input speech with the stored templates to finally display the sign language in video format. Empirical results show that the system has 80.3% recognition rate.

  3. Evaluation of Simple Causal Message Logging for Large-Scale Fault Tolerant HPC Systems

    Energy Technology Data Exchange (ETDEWEB)

    Bronevetsky, G; Meneses, E; Kale, L V

    2011-02-25

    The era of petascale computing brought machines with hundreds of thousands of processors. The next generation of exascale supercomputers will make available clusters with millions of processors. In those machines, mean time between failures will range from a few minutes to few tens of minutes, making the crash of a processor the common case, instead of a rarity. Parallel applications running on those large machines will need to simultaneously survive crashes and maintain high productivity. To achieve that, fault tolerance techniques will have to go beyond checkpoint/restart, which requires all processors to roll back in case of a failure. Incorporating some form of message logging will provide a framework where only a subset of processors are rolled back after a crash. In this paper, we discuss why a simple causal message logging protocol seems a promising alternative to provide fault tolerance in large supercomputers. As opposed to pessimistic message logging, it has low latency overhead, especially in collective communication operations. Besides, it saves messages when more than one thread is running per processor. Finally, we demonstrate that a simple causal message logging protocol has a faster recovery and a low performance penalty when compared to checkpoint/restart. Running NAS Parallel Benchmarks (CG, MG and BT) on 1024 processors, simple causal message logging has a latency overhead below 5%.

    Hospital real-time location systems (RTLS) are increasing efficiency and reducing operational costs, but room access tags are necessary. We developed three iPhone 5 applications for an RTLS and communications using Bluetooth low energy (BLE). The applications were: Peripheral device tags, Central beacons, and a Monitor. A Peripheral communicated with a Central using BLE. The Central communicated with a Monitor using sockets on TCP/IP (Transmission Control Protocol/Internet Protocol) via a WLAN (wireless local area network). To determine a BLE threshold level for the received signal strength indicator (RSSI), relationships between signal strength and distance were measured in our laboratory and on the terrace. The BLE RSSI threshold was set at -70 dB, about 10 m. While an individual with a Peripheral moved around in a concrete building, the Peripheral was captured in a few 10-sec units at about 10 m from a Central. The Central and Monitor showed and saved the approach events, location, and Peripheral's nickname sequentially in real time. Remote Centrals also interactively communicate with Peripherals by intermediating through Monitors that found the nickname in the event database. Trial applications using BLE on iPhones worked well for patient tracking, and messaging in indoor environments.

    2012-01-01

    Full Text Available Operators of parking guidance and information systems (PGIS often encounter difficulty in determining when and how to provide reliable car park availability information to drivers. Reliability has become a key factor to ensure the benefits of urban PGIS. The present paper is the first to define the guiding parking reliability of urban parking variable message signs (VMSs. By analyzing the parking choice under guiding and optional parking lots, a guiding parking reliability model was constructed. A mathematical program was formulated to determine the guiding parking reliability of VMS. The procedures were applied to a numerical example, and the factors that affect guiding reliability were analyzed. The quantitative changes of the parking berths and the display conditions of VMS were found to be the most important factors influencing guiding reliability. The parking guiding VMS achieved the best benefit when the parking supply was close to or was less than the demand. The combination of a guiding parking reliability model and parking choice behavior offers potential for PGIS operators to reduce traffic congestion in central city areas.

  7. Error Correction Coding Meets Cyber-Physical Systems: Message-Passing Analysis of Self-Healing Interdependent Networks

    CERN Document Server

    2016-01-01

    Coupling cyber and physical systems gives rise to numerous engineering challenges and opportunities. An important challenge is the contagion of failure from one system to another, which can lead to large-scale cascading failures. However, the \\textit{self-healing} ability emerges as a valuable opportunity where the overlaying cyber network can cure failures in the underlying physical network. To capture both self-healing and contagion, this paper considers a graphical model representation of an interdependent cyber-physical system, in which nodes represent various cyber or physical functionalities, and edges capture the interactions between the nodes. A message-passing algorithm used in low-density parity-check codes is extended to this representation to study the dynamics of failure propagation and healing. By applying a density evolution analysis to this algorithm, network reaction to initial disruptions is investigated. It is proved that as the number of message-passing iterations increases, the network re...

    2004-11-01

    Using a voice key is a popular method for recording vocal response times in a variety of language production tasks. This article describes a class module called VoiceRelay that can be easily utilized in Visual Basic programs for voice key operation. This software-based voice key offers the precision of traditional voice keys (although accuracy is system dependent), as well as the flexibility of volume and sensitivity control. However, VoiceRelay is a considerably less expensive alternative for recording vocal response times because it operates with existing PC hardware and does not require the purchase of external response boxes or additional experiment-generation software. A sample project demonstrating implementation of the VoiceRelay class module may be downloaded from the Psychonomic Society Web archive, www.psychonomic.org/archive.

    2005-01-01

    The digital communication of two-dimensional messages is investigated when two solid state multi-mode chaotic lasers are employed in a master-slave configuration. By introducing the time derivative of intensity difference between the receiver (carrier) and the transmittal (carrier plus signal), several signals can be encoded into a single pulse. If one signal contains several binary bits, two-dimensional messages in the form of a matrix can be encoded and transmitted on a single pulse. With these improvements in secure communications using chaotic multi-mode lasers, not only the transmission rate can be increased but also the privacy can be enhanced greatly.

    2017-01-01

    We consider a problem facing by an international telecommunication services company in maximizing its profit. From voice services by controlling cost and business partnership. The competitiveness in this industry is very high, so that any efficiency from controlling cost and business partnership can help the company to survive in the very high competitiveness situation. The company trades voice traffic with a large number of business partners. There are four trading schemes that can be chosen by this company, namely, flat rate, class tiering, volume commitment, and revenue capped. Each scheme has a specific characteristic on the rate and volume deal, where the last three schemes are regarded as strategic schemes to be offered to business partner to ensure incoming traffic volume for both parties. This company and each business partner need to choose an optimal agreement in a certain period of time that can maximize the company’s profit. In this agreement, both parties agree to use a certain trading scheme, rate and rate/volume/revenue deal. A decision support system is then needed in order to give a comprehensive information to the sales officers to deal with the business partners. This paper discusses the mathematical model of the optimal decision for incoming traffic volume control, which is a part of the analysis needed to build the decision support system. The mathematical model is built by first performing data analysis to see how elastic the incoming traffic volume is. As the level of elasticity is obtained, we then derive a mathematical modelling that can simulate the impact of any decision on trading to the revenue of the company. The optimal decision can be obtained from these simulations results. To evaluate the performance of the proposed method we implement our decision model to the historical data. A software tool incorporating our methodology is currently in construction.

  16. A Systemic Functional Approach to the Passive Voice in English into Spanish Translation: Thematic Development in a Medical Research Article

    Directory of Open Access Journals (Sweden)

    Rodríguez-Vergara Daniel

    2017-01-01

    Full Text Available The purpose of this study was to explore, from the perspective of Systemic Functional Grammar, how passive clauses in a medical research article were translated into Spanish, specifically if they were kept in the passive voice, were changed into the active voice, or were turned into some other structure, and if voice change in the translated version affected the original thematic development. The medical paper chosen for this study was originally written in English and published in an Anglophone journal; it was then translated into Spanish and published in a Mexican journal. Both the original and the translated article were analyzed in terms of Theme and Rheme; all of the instances of passive and active voice were quantified and compared. The results show that in some cases the original thematic patterns were modified in the translation due to the use of the reflexive passive in Spanish, which results in the fronting of the verb in the sentences, thereby causing a change of Themes in the paragraphs with respect to the original structure. This study contributes to our understanding of the function of passive constructions in English and Spanish and its relationship with thematic progression.

    Energy Technology Data Exchange (ETDEWEB)

    Papp, III, Albert Louis [Univ. of California, Davis, CA (United States)

    1997-09-01

    This dissertation describes a methodology and example implementation for the dynamic regulation of temporally overlapping auditory messages in computer-user interfaces. The regulation mechanism exists to schedule numerous overlapping auditory messages in such a way that each individual message remains perceptually distinct from all others. The method is based on the research conducted in the area of auditory scene analysis. While numerous applications have been engineered to present the user with temporally overlapped auditory output, they have generally been designed without any structured method of controlling the perceptual aspects of the sound. The method of scheduling temporally overlapping sounds has been extended to function in an environment where numerous applications can present sound independently of each other. The Centralized Audio Presentation System is a global regulation mechanism that controls all audio output requests made from all currently running applications. The notion of multimodal objects is explored in this system as well. Each audio request that represents a particular message can include numerous auditory representations, such as musical motives and voice. The Presentation System scheduling algorithm selects the best representation according to the current global auditory system state, and presents it to the user within the request constraints of priority and maximum acceptable latency. The perceptual conflicts between temporally overlapping audio messages are examined in depth through the Computational Auditory Scene Synthesizer. At the heart of this system is a heuristic-based auditory scene synthesis scheduling method. Different schedules of overlapped sounds are evaluated and assigned penalty scores. High scores represent presentations that include perceptual conflicts between over-lapping sounds. Low scores indicate fewer and less serious conflicts. A user study was conducted to validate that the perceptual difficulties predicted by

    1990-07-01

    To provide a means of rendering complex computer architectures languages and input/output modalities transparent to experienced and inexperienced users research is being conducted to develop a voice driven/voice response computer graphics imaging system. The system will be used for reconstructing and displaying computed tomography and magnetic resonance imaging scan data. In conjunction with this study an artificial intelligence (Al) control strategy was developed to interface the voice components and support software to the computer graphics functions implemented on the Sun Microsystems 4/280 color graphics workstation. Based on generated text and converted renditions of verbal utterances by the user the Al control strategy determines the user''s intent and develops and validates a plan. The program type and parameters within the plan are used as input to the graphics system for reconstructing and displaying medical image data corresponding to that perceived intent. If the plan is not valid the control strategy queries the user for additional information. The control strategy operates in a conversation mode and vocally provides system status reports. A detailed examination of the various AT techniques is presented with major emphasis being placed on their specific roles within the total control strategy structure. 1.

    Full Text Available A typical speech recognition system is push-to-talk operated that requires activation. However for those who use hands-busy applications, movement may by restricted or impossible. One alternative is to use Speech-Only Interface. The proposed method that is called Wake-Up-Word Speech Recognition (WUW-SR that utilizes speech only interface. A WUW-SR system would allow the user to activate systems (Cell phone, Computer, etc. with only speech commands instead of manual activation. The trend in WUW-SR hardware design is towards implementing a complete system on a single chip intended for various applications. This paper presents an experimental FPGA design and implementation of a novel architecture of a real time feature extraction processor that includes: Voice Activity Detector (VAD, and features extraction, MFCC, LPC, and ENH_MFCC. In the WUW-SR system, the recognizer front-end with VAD is located at the terminal which is typically connected over a data network(e.g., serverfor remote back-end recognition. VAD is responsible for segmenting the signal into speech-like and non-speech-like segments. For any given frame VAD reports one of two possible states: VAD_ON or VAD_OFF. The back-end is then responsible to score the features that are being segmented during VAD_ON stage. The most important characteristic of the presented design is that it should guarantee virtually 100% correct rejection for non-WUW (out of vocabulary words - OOV while maintaining correct acceptance rate of 99.9% or higher (in vocabulary words - INV. This requirement sets apart WUW-SR from other speech recognition tasks because no existing system can guarantee 100% reliability by any measure.

    Voice has been neglected in research on advertising and persuasion. The present study examined the influence of voice and sex on the credibility of the voice source in a banking telemarketing context as well as with regards to the attitude toward the advertisement, and subjects' behavioral intention. An experiment using voices of a man and a woman was conducted. A recorded mock-telemarketing message consisted of an advertisement for an ATM card offered by a Canadian bank. Subjects were undergraduate students (N=399; 71.6% women, 28.4% men; M age=26.5 yr., SD = 7.4). They completed a questionnaire after hearing the message in telemarketing conditions. Analysis indicated a moderate intensity, an unmarked intonation, and a fast speech rate are associated with a more credible source than the other combinations. Sex was not a significant moderator in the relationship between voice characteristics and source credibility. Voice characteristics significantly affected attitudes toward the advertisement and behavioral intention.

    Mobile health (mHealth) services cannot easily adapt to users' unique needs. We used simulations of text messaging (SMS) for improving medication adherence to demonstrate benefits of interventions using reinforcement learning (RL). We used Monte Carlo simulations to estimate the relative impact of an intervention using RL to adapt SMS adherence support messages in order to more effectively address each non-adherent patient's adherence barriers, e.g., forgetfulness versus side effect concerns. SMS messages were assumed to improve adherence only when they matched the barriers for that patient. Baseline adherence and the impact of matching messages were estimated from literature review. RL-SMS was compared in common scenarios to simple reminders, random messages, and standard tailoring. RL could produce a 5-14% absolute improvement in adherence compared to current approaches. When adherence barriers are not accurately reported, RL can recognize which barriers are relevant for which patients. When barriers change, RL can adjust message targeting. RL can detect when messages are sent too frequently causing burnout. RL systems could make mHealth services more effective.

    A self teaching image processing and voice recognition based system is developed to educate visually impaired children, chiefly in their primary education. System comprises of a computer, a vision camera, an ear speaker and a microphone. Camera, attached with the computer system is mounted on the ceiling opposite (on the required angle) to the desk on which the book is placed. Sample images and voices in the form of instructions and commands of English, Urdu alphabets, Numeric Digits, Operators and Shapes are already stored in the database. A blind child first reads the embossed character (object) with the help of fingers than he speaks the answer, name of the character, shape etc into the microphone. With the voice command of a blind child received by the microphone, image is taken by the camera which is processed by MATLAB® program developed with the help of Image Acquisition and Image processing toolbox and generates a response or required set of instructions to child via ear speaker, resulting in self education of a visually impaired child. Speech recognition program is also developed in MATLAB® with the help of Data Acquisition and Signal Processing toolbox which records and process the command of the blind child.

    Full Text Available As people increasingly communicate via asynchronous non-spoken modes on mobile devices, particularly text messaging (e.g., SMS, longstanding assumptions and practices of social measurement via telephone survey interviewing are being challenged. In the study reported here, 634 people who had agreed to participate in an interview on their iPhone were randomly assigned to answer 32 questions from US social surveys via text messaging or speech, administered either by a human interviewer or by an automated interviewing system. 10 interviewers from the University of Michigan Survey Research Center administered voice and text interviews; automated systems launched parallel text and voice interviews at the same time as the human interviews were launched. The key question was how the interview mode affected the quality of the response data, in particular the precision of numerical answers (how many were not rounded, variation in answers to multiple questions with the same response scale (differentiation, and disclosure of socially undesirable information. Texting led to higher quality data-fewer rounded numerical answers, more differentiated answers to a battery of questions, and more disclosure of sensitive information-than voice interviews, both with human and automated interviewers. Text respondents also reported a strong preference for future interviews by text. The findings suggest that people interviewed on mobile devices at a time and place that is convenient for them, even when they are multitasking, can give more trustworthy and accurate answers than those in more traditional spoken interviews. The findings also suggest that answers from text interviews, when aggregated across a sample, can tell a different story about a population than answers from voice interviews, potentially altering the policy implications from a survey.

    To present the technical background and the development of a procedure that enriches the semantics of Health Level Seven version 2 (HL7v2) messages for software-intensive systems in telemedicine trauma care. This study followed a multilevel model-driven approach for the development of semantically interoperable health information systems. The Pre-Hospital Trauma Life Support (PHTLS) ABCDE protocol was adopted as the use case. A prototype application embedded the semantics into an HL7v2 message as an eXtensible Markup Language (XML) file, which was validated against an XML schema that defines constraints on a common reference model. This message was exchanged with a second prototype application, developed on the Mirth middleware, which was also used to parse and validate both the original and the hybrid messages. Both versions of the data instance (one pure XML, one embedded in the HL7v2 message) were equally validated and the RDF-based semantics recovered by the receiving side of the prototype from the shared XML schema. This study demonstrated the semantic enrichment of HL7v2 messages for intensive-software telemedicine systems for trauma care, by validating components of extracts generated in various computing environments. The adoption of the method proposed in this study ensures the compliance of the HL7v2 standard in Semantic Web technologies.

    As computerization in the nursing field has been recently progressing, an electronic nursing record system is gradually introduced in the medical institution in Japan. Although it is expected for the electronic nursing record system to reduce the load of nursing work, the conventional keyboard operation is used for information input of the present electronic nursing record system and it has some problems concerning the input time and the operationability for common nurses who are unfamiliar with the computer operation. In the present study, we conducted a basic study on application of voice recognition input to an electronic nursing record system. The voice input is recently introduced to an electronic medical record system in a few clinics. However, so far the entered information cannot be processed because the information of the medical record must be entered as a free sentence. Therefore, we contrived a template for an electronic nursing record system and introduced it to the system for simple information entry and easy processing of the entered information in this study. Furthermore, an input experiment for evaluation of the voice input with the template was carried out by voluntary subjects for evaluation of the function as an input interface of an electronic nursing record system. The results of the experiment revealed that the input time by the voice input is obviously fast compared with that by the keyboard input and operationability of the voice input was superior to the keyboard input although all subjects had inexperience of the voice input. As a result, it was suggested our method, the voice input using the template made by us, might be useful for an input interface of an electronic nursing record system.

    Full Text Available The emerging large-scale/massive multi-input multioutput (MIMO system combined with orthogonal frequency division multiplexing (OFDM is considered a key technology for its advantage of improving the spectral efficiency. In this paper, we introduce an iterative detection algorithm for uplink large-scale multiuser MIMO-OFDM communication systems. We design a Main-Branch structure iterative turbo detector using the Approximate Message Passing algorithm simplified by linear approximation (AMP-LA and using the Mean Square Error (MSE criterion to calculate the correlation coefficients between main detector and branch detector for the given iteration. The complexity of our method is compared with other detection algorithms. The simulation results show that our scheme can achieve better performance than the conventional detection methods and have the acceptable complexity.

    To study the impact on adolescent immunization rates of direct messages to parents/guardians. Electronic health record rules identified adolescents needing an immunization. Parents/guardians of adolescents were messaged via a single vendor using automated text, prerecorded voice, and/or postcard. Parents/guardians of 3,393 patients, ages 11-18 years, with one or more primary care visits in the prior 2 years, identified as needing (average of 2.04 years) a vaccination (meningococcal conjugate, human papillomavirus, or tetanus, diphtheria, and pertussis vaccines) were messaged (mean age, 14 years; 50% male; 38% African-American; 23% white; 19% Hispanic; and 79% public health insurance). A total of 7,094 messages were sent: 3,334 automated voice (47%), 2,631 texts (37%), and 1,129 postcards (16%). After the first message, 865 adolescents (25.5%) received at least one vaccine. Within 24 weeks of messaging 1,324 vaccines (745 human papillomavirus; 403 meningococcal conjugate; and 176 tetanus, diphtheria, and pertussis vaccines) occurred in 959 visits (83.8% physician visits and 16.2% nurse visits). Average visits generated $204 gross reimbursement for $1.77 in messaging expenses per vaccine given. No differences in immunization completion rates occurred by age, gender, race/ethnicity, or insurance type. At 24 weeks, one message was more effective than two or three messages (35.6%, 19.4%, and 24.1% effectiveness, respectively; p Texts and postcards correlated with more vaccination visits (38.8% and 40.1%, respectively) than phone calls (31.5%; p = .04). More vaccines due led to increasing message effectiveness. Automated texts, voice messages, and postcards had a significant positive effect on vaccination rates in adolescents needing vaccination and required minimal financial expenditure.

  19. Syllogisms delivered in an angry voice lead to improved performance and engagement of a different neural system compared to neutral voice

    Directory of Open Access Journals (Sweden)

    Kathleen Walton Smith

    2015-05-01

    Full Text Available Despite the fact that most real-world reasoning occurs in some emotional context, very little is known about the underlying behavioral and neural implications of such context. To further understand the role of emotional context in logical reasoning we scanned 15 participants with fMRI while they engaged in logical reasoning about neutral syllogisms presented through the auditory channel in a sad, angry, or neutral tone of voice. Exposure to angry voice led to improved reasoning performance compared to exposure to sad and neutral voice. A likely explanation for this effect is that exposure to expressions of anger increases selective attention toward the relevant features of target stimuli, in this case the reasoning task. Supporting this interpretation, reasoning in the context of angry voice was accompanied by activation in the superior frontal gyrus—a region known to be associated with selective attention. Our findings contribute to a greater understanding of the neural processes that underlie reasoning in an emotional context by demonstrating that two emotional contexts, despite being of the same (negative valence, have different effects on reasoning.

    Full Text Available Abstract Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.

    Telephone reminder systems have been used to assist in the treatment of many chronic diseases. However, it is unclear if these systems can increase medication and appointment adherence in patients with diabetes without direct patient-provider telephone contact. We tested the feasibility of using an automated telephone reminder system (ATRS) to deliver reminder messages to 253 adults with diabetes enrolled in a randomized controlled trial. Eighty-four percent of the patients were able to register using voice recognition and at least one reminder was delivered to 95% of registered patients over a period of 7.5 months. None of the demographic features studied predicted a patient's ability to enroll or to receive reminder calls. At the end of the study, 63% of patients indicated that they wished to continue to receive ATRS calls. The level of system use as determined by the number of received reminder calls was not associated with a change in the number of physician visits or diabetes-related laboratory tests during follow-up. The clinical benefits and sustainability of ATRS remain unproven, but our results indicate that an automated reminder system can be effective for providing messages to a large group of older patients with diabetes.

    This paper describes the design, modeling, optimization, and validation of an active vibration isolation system using a voice coil motor. The active vibration isolating method was constructed with a passive isolator and an active isolator. A spring was used for passive isolating; an actuator was used for active isolating. The proposed active vibration isolation system (AVIS) can isolate disturbances for many kinds of instruments. Until now, developed AVIS were able to isolate a six degree-of-freedom disturbance effectively. This paper proposes the realization of such a six degree-of-freedom active vibration isolation system that can work as a bench top device for precision measuring machines such as atomic force microscope, scanning probe microscope, etc.

  16. The design of a digital voice data compression technique for orbiter voice channels

    Science.gov (United States)

    1975-01-01

    Voice bandwidth compression techniques were investigated to anticipate link margin difficulties in the shuttle S-band communication system. It was felt that by reducing the data rate on each voice channel from the baseline 24 (or 32) Kbps to 8 Kbps, additional margin could be obtained. The feasibility of such an alternate voice transmission system was studied. Several factors of prime importance that were addressed are: (1) achieving high quality voice at 8 Kbps; (2) performance in the presence of the anticipated shuttle cabin environmental noise; (3) performance in the presence of the anticipated channel error statistics; and (4) minimal increase in size, weight, and power over the current baseline voice processor.

    Full Text Available Use of blood glucose (BG meters in the self-monitoring of blood glucose (SMBG significantly lowers the risk of diabetic complications. With several BG meters now commercially available, the International Organization for Standardization (ISO ensures that each BG meter conforms to a set degree of accuracy. Although adherence to ISO guidelines is a prerequisite for commercialization in Europe, several BG meters claim to meet the ISO guidelines yet fail to do so on internal validation. We conducted a study to determine whether the accuracy of the GlucoRx Nexus TD-4280 meter, utilized by our department for its cost-effectiveness, complied with ISO guidelines. 105 patients requiring laboratory blood glucose analysis were randomly selected and reference measurements were determined by the UniCel DxC 800 clinical system. Overall the BG meter failed to adhere to the ≥95% accuracy criterion required by both the 15197:2003 (overall accuracy 92.4% and 15197:2013 protocol (overall accuracy 86.7%. Inaccurate meters have an inherent risk of over- and/or underestimating the true BG concentration, thereby risking patients to incorrect therapeutic interventions. Our study demonstrates the importance of internally validating the accuracy of BG meters to ensure that its accuracy is accepted by standardized guidelines.

    2012-04-01

    The tsunami disaster affecting the Indian Ocean region on Christmas 2004 demonstrated very clearly the shortcomings in tsunami detection, public warning processes as well as intergovernmental warning message exchange in the Indian Ocean region. In that regard, early warning systems require that the dissemination of early warning messages has to be executed in way that ensures that the message delivery is timely; the message content is understandable, usable and accurate. To that end, diverse and multiple dissemination channels must be used to increase the chance of the messages reaching all affected persons in a hazard scenario. In addition to this, usage of internationally accepted standards for the warning dissemination such as the Common Alerting Protocol (CAP) and Emergency Data Exchange Language (EDXL) Distribution Element specified by the Organization for the Advancement of Structured Information Standards (OASIS) increase the interoperability among different warning systems enabling thus the concept of system-of-systems proposed by GEOSS. The project Distant Early Warning System (DEWS), co-funded by the European Commission under the 6th Framework Programme, aims at strengthening the early warning capacities by building an innovative generation of interoperable tsunami early warning systems based on the above mentioned concepts following a Service-oriented Architecture (SOA) approach. The project focuses on the downstream part of the hazard information processing where customized, user-tailored warning messages and alerts flow from the warning centre to the responsible authorities and/or the public with their different needs and responsibilities. The information logistics services within DEWS generate tailored EDXL-DE/CAP warning messages for each user that must receive the message according to their preferences, e.g., settings for language, interested areas, dissemination channels, etc.. However, the significant difference in the implementation and

    Full Text Available The use of wireless automation in almost all the fields of power, gas and water generation, distribution and billing has come of age. Here with the inclusion of wireless communication with the automation may lead to paradigm change in the current trend. The design presents a new methodology for avoiding the high construction and maintenance costs in the existing meter reading technology. Apart the use of wireless meter reading with network technologies has become need of the day. The designed system avoids the human intervention in Power Management. The Consumer has to pay the bill in time, if couldn’t, the power connection may be disconnected automatically from the remote server. It displays the corresponding billing information on LCD and data is sent to the server through the GSM Module. The ARM7 based hardware system consists of a processor core board and the peripheral board. The entire programming for microcontroller operation is based on Embedded C Language. This system provides efficient meter reading, avoiding the billing error and reduces the maintenance cost. This paper also addresses advantages of implementing the GSM communication module and design detail and discusses the advanced security of the data communications.

  6. Varieties of Voice-Hearing: Psychics and the Psychosis Continuum.

    Powers, Albert R; Kelley, Megan S; Corlett, Philip R

    2017-01-01

    Hearing voices that are not present is a prominent symptom of serious mental illness. However, these experiences may be common in the non-help-seeking population, leading some to propose the existence of a continuum of psychosis from health to disease. Thus far, research on this continuum has focused on what is impaired in help-seeking groups. Here we focus on protective factors in non-help-seeking voice-hearers. We introduce a new study population: clairaudient psychics who receive daily auditory messages. We conducted phenomenological interviews with these subjects, as well as with patients diagnosed with a psychotic disorder who hear voices, people with a diagnosis of a psychotic disorder who do not hear voices, and matched control subjects (without voices or a diagnosis). We found the hallucinatory experiences of psychic voice-hearers to be very similar to those of patients who were diagnosed. We employed techniques from forensic psychiatry to conclude that the psychics were not malingering. Critically, we found that this sample of non-help-seeking voice hearers were able to control the onset and offset of their voices, that they were less distressed by their voice-hearing experiences and that, the first time they admitted to voice-hearing, the reception by others was much more likely to be positive. Patients had much more negative voice-hearing experiences, were more likely to receive a negative reaction when sharing their voices with others for the first time, and this was subsequently more disruptive to their social relationships. We predict that this sub-population of healthy voice-hearers may have much to teach us about the neurobiology, cognitive psychology and ultimately the treatment of voices that are distressing. © The Author 2016.

    We have demonstrated previously that an individualized health management system using advanced medical information technology, named ubiquitous (u)-healthcare, was helpful in achieving better glycemic control than routine care. Recently, we generated a new u-healthcare system using a voice inception technique for elderly diabetic patients to communicate information about their glucose control, physical activity, and diet more easily. In a randomized clinical trial, 70 diabetic patients aged 60-85 years were assigned randomly to a standard care group or u-healthcare group for 6 months. The primary end points were the changes in glycated hemoglobin (HbA1c) and glucose fluctuation assessed by the mean amplitude glycemic excursion (MAGE). Changes in body weight, lifestyle, and knowledge about diabetes were also investigated. After 6 months, the HbA1c levels decreased significantly in the u-healthcare group (from 8.6 ± 1.0% to 7.5 ± 0.6%) compared with the standard care group (from 8.7 ± 0.9% to 8.2 ± 1.1%, P < 0.01). The MAGE decreased more in the u-healthcare group than in the standard care group. Systolic blood pressure and body weight decreased and liver functions improved in the u-healthcare group, but not in the standard care group. The u-healthcare system with voice inception technique was effective in achieving glycemic control without hypoglycemia in elderly diabetic patients (Clinicaltrials.gov: NCT01891474).

    An overview of ESA's approach towards the introduction of Land Mobile Communications in Europe is presented. Emphasis is placed on a description of the payload called EMS to be launched on a host satellite, the Italsat-F2 spacecraft, and the definition of services which are most appropriate for a first-generation-operating Land Mobile Satellite System, namely, PRODAT, a message-handling system, and Europhone, an original approach to 'voice' systems. Attention is given to the EMS payload, characteristics, and capacity, the IF processor and channelization, and market considerations. It is shown that the optimization of the satellite characteristics and the mix of services to be provided are the key elements of a successful entry into the market.

    2014-07-01

    In this study, the dynamics of decisions in complex networks subject to external fields are studied within a Markov process framework using nonlinear dynamical systems theory. A mathematical discrete-time model is derived using a set of basic assumptions regarding the convincement mechanisms associated with two competing opinions. The model is analyzed with respect to the multiplicity of critical points and the stability of extinction states. Sufficient conditions for extinction are derived in terms of the convincement probabilities and the maximum eigenvalues of the associated connectivity matrices. The influences of exogenous (e.g., mass media-based) effects on decision behavior are analyzed qualitatively. The current analysis predicts: (i) the presence of fixed-point multiplicity (with a maximum number of four different fixed points), multi-stability, and sensitivity with respect to the process parameters; and (ii) the bounded but significant impact of exogenous perturbations on the decision behavior. These predictions were verified using a set of numerical simulations based on a scale-free network topology.

    2017-08-01

    Autism Spectrum Disorder (ASC) has widely gained the common attention from the public especially autistic communities. Individuals with ASC are said to have poor verbal skills and this affects them in carrying out their daily basis which they are afraid to expose themselves to the world due to their problems. ASC is diagnosed among children ranging from ages 5-12 years old and they suffer from the abnormal functioning of the brain which in turn causes lack of development activities. Thus, studies have shown that diagrammatic approaches help children with ASC to overcome their issues and improvise their visual and verbal skills. Picture Exchange Communication System or PECS consists of a series of illustrated cards and each cards has its own illustration with a caption on it. These children will understand the cards and they can compile several other cards to form sentences. This paper presents a mobile application called the Prospect, which has been developed using the agile development model for digital representation of PECS. The application is hoped to enhance the learning process and a better yielding results.

    2016-08-01

    Full Text Available Articular syndrome is one of the main signs of the microscopic polyangiitis (MPA, which in some regions of the Earth accounts for over 90 % of all systemic vasculitis (SV, associated with antineutrophil cytoplasmic antibodies (ANCA. It was found that 5 years after the manifestation of MPA, a progressive reduction of the para-articular (epiphyseal bone mineral density and destruction of the joints begin to form. Many questions related to the nature of the course of joint pathology in specific ANCA-SV require further study. Objective: to evaluate joint damage in patients with MPA and the relationship with extra-articular pathology. Material and methods. We study involved 89 patients with MPA aged 18–78 years old, among which there were 44 % men and 56 % women. The duration of the disease from the first signs of manifestation was 7 years. Acute or subacute course of MPA has been registered in 27 % of cases, and in the rest — chronic one; I degree of the activity of pathological process has been detected in 10 % of cases, II —in 32 %, III — is 58 %. Results. The joint involvement is observed in 60 % of patients with MPA, in 40 % of cases it occurs in the form of oligoarthritis, depends on the presence of pathology in skeletal muscles, pneumopathy or peripheral neuropathy. Clinical, radiological and sonographic signs of articular pathology in MPA are closely associated with patients’ age, disease duration, lesions of the heart, kidneys and skin. In the pathogenetic structures of arthropathy in patients with MPA, C-reactive protein (CRP and circulating immune complexes (CIC are involved, and the nature of ANCA (antibodies to myeloperoxidase and proteinase-3 is of small value, while the high blood levels of rheumatoid factor (RF have certain prognosis-negative significance in terms of the severity of joint pathology. Conclusion. Unfavorable prognostic criteria for the development of joint pathology in patients with MPA are indicators in the

    Full Text Available Studies show a high prevalence of vocal alterations among teachers. One of the criteria for the establishment of the prevalence of vocal alteration is based on teachers' self-perception. Objective: This study aimed at comparing voice-disordered quality of life measures between a group of teachers who reported vocal alteration and a group of teachers who did not, by verifying the teachers' perception regarding the impact of vocal alteration in the different dimensions of voice quality of life. Material and Methods: Ninety-seven (97 teachers answered three psychometric protocols of voice quality of life: Voice Handicap Index (VHI, Voice-Related Quality of Life (V-RQOL, and the Voice Activity Participation Profile (VAPP, in addition to a questionnaire for characterization of the sample. Results: The results were that 39.8% of the teachers reported vocal alteration. When comparing voice measures between the groups (with and without vocal alteration, statistically significant differences were observed: the total score of VHI, total score of V-RQOL and total score of VAAP and its dimensions. It was also verified that the physical dimension of VHI has a greater impact among the dimensions of this protocol. For VRQOL, the most striking dimension was the physical functioning domain, both indicating the laryngeal discomfort and the impact of voice on communication, in teachers with and without complaints. As for VAAP, no domain prevailed over the others in the group with no complaints. For teachers with complaints, three domains, i.e., daily communication, work, and emotions have a greater impact than social communication. The limitation and restriction scores were calculated as well, and it was observed the limitation of activities is greater than the restriction of activities, both in the group with and the group without complaints. Conclusion: One may conclude that the teachers who reported vocal alterations better realize the impact of voice in

    Driver distraction is a growing and pervasive issue that requires multiple solutions. Voice-recognition (V-R) systems may decrease the visual-manual (V-M) demands of a wide range of in-vehicle system and smartphone interactions. However, the degree that V-R systems integrated into vehicles or available in mobile phone applications affect driver distraction is incompletely understood. A comprehensive meta-analysis of experimental studies was conducted to address this knowledge gap. To meet study inclusion criteria, drivers had to interact with a V-R system while driving and doing everyday V-R tasks such as dialing, initiating a call, texting, emailing, destination entry or music selection. Coded dependent variables included detection, reaction time, lateral position, speed and headway. Comparisons of V-R systems with baseline driving and/or a V-M condition were also coded. Of 817 identified citations, 43 studies involving 2000 drivers and 183 effect sizes (r) were analyzed in the meta-analysis. Compared to baseline, driving while interacting with a V-R system is associated with increases in reaction time and lane positioning, and decreases in detection. When V-M systems were compared to V-R systems, drivers had slightly better performance with the latter system on reaction time, lane positioning and headway. Although V-R systems have some driving performance advantages over V-M systems, they have a distraction cost relative to driving without any system at all. The pattern of results indicates that V-R systems impose moderate distraction costs on driving. In addition, drivers minimally engage in compensatory performance adjustments such as reducing speed and increasing headway while using V-R systems. Implications of the results for theory, design guidelines and future research are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Every clinical physicist I have asked readily acknowledges the great desirability of a 3D dosimetry system for the verification of advanced radiation therapy treatments. An accurate and practical 3D dosimetry system would greatly strengthen the foundation of quality assurance in radiation therapy by enabling a rigorous and comprehensive whole system test. Such systems are now emerging, and the innovations and progress that led to them are remarkably captured in the proceedings of five prior DOSGEL conferences, the last three of which are freely available in the Journal of Physics: Conference Series. These meetings included a focus on the technical challenges of various approaches to 3D dosimetry. When considering plans for the present 6th meeting, the scientific committee recognized that the field has matured, and a broader focus was desirable, including a strengthening of the clinical and applications component, while preserving a strong technical component. There was also the desire to embrace a variety of other semi-3D techniques which have also recently emerged to implementation in the clinic. In accordance with these sentiments, the committee approved changing the name of the conference from the International Conference on Radiotherapy Gel Dosimetry (DOSGEL) to the International Conference on 3D Radiation Dosimetry (IC3DDose) and to the following objectives - Conference Objectives: 1. To provide a forum to discuss the latest research and developments in 3D and advanced radiation dosimetry. 2. To elevate the quality of radiation therapy treatments (quality assurance QA) through improved clinical dosimetry. 3. To explore the dosimetric challenges posed by modern radiation treatment techniques 4. To energize and diversify dosimetry research and clinical practice by encouraging interaction and synergy between advanced, 3D, and semi-3D dosimetry techniques The scientific program of the IC3DDose2010 meeting has been crafted to meet the objectives listed above, and

Nonspeaking voice professionals mainly include singers, whereas speaking voice professionals include the rest of the voice professionals. Although both of these groups have high vocal demands, it is currently unknown whether both groups show similar voice changes after their daily voice use. Comparison of these two subgroups of voice professionals has never been done before. This study aimed to compare the speaking voice of speaking and nonspeaking voice professionals with no obvious vocal fold pathology or voice-related complaints on the day of assessment. After obtaining relevant voice-related history, voice analysis and videostroboscopy were performed in 50 speaking and 50 nonspeaking voice professionals. Speaking voice professionals showed significantly higher incidence of voice-related complaints as compared with nonspeaking voice professionals. Voice analysis revealed that most acoustic parameters including fundamental frequency, jitter percent, and harmonic-to-noise ratio were significantly higher in speaking voice professionals, whereas videostroboscopy did not show any significant difference between the two groups. This is the first study of its kind to analyze the effect of daily voice use in the two subgroups of voice professionals with no obvious vocal fold pathology. We conclude that voice professionals should not be considered as a homogeneous group. The detrimental effects of excessive voice use were observed to occur more significantly in speaking voice professionals than in nonspeaking voice professionals.

    Full Text Available Two experiments investigated deaf individuals' ability to discriminate between same-sex talkers based on vibrotactile stimulation alone. Nineteen participants made same/different judgments on pairs of utterances presented to the lower back through voice coils embedded in a conforming chair. Discrimination of stimuli matched for F0, duration, and perceived magnitude was successful for pairs of spoken sentences in Experiment 1 (median percent correct = 83% and pairs of vowel utterances in Experiment 2 (median percent correct = 75%. Greater difference in spectral tilt between "different" pairs strongly predicted their discriminability in both experiments. The current findings support the hypothesis that discrimination of complex vibrotactile stimuli involves the cortical integration of spectral information filtered through frequency-tuned skin receptors.

  9. Eliminating livelock by assigning the same priority state to each message that is input into a flushable routing system during N time intervals

    Science.gov (United States)

    Faber, V.

    1994-11-29

    Livelock-free message routing is provided in a network of interconnected nodes that is flushable in time T. An input message processor generates sequences of at least N time intervals, each of duration T. An input register provides for receiving and holding each input message, where the message is assigned a priority state p during an nth one of the N time intervals. At each of the network nodes a message processor reads the assigned priority state and awards priority to messages with priority state (p-1) during an nth time interval and to messages with priority state p during an (n+1) th time interval. The messages that are awarded priority are output on an output path toward the addressed output message processor. Thus, no message remains in the network for a time longer than T. 4 figures.

    A simulation in the B747-400 was conducted at NASA Ames Research Center that compared how crews handled voice and data link air traffic control (ATC) messages in a single medium versus a mixed voice and data link ATC environment The interval between ATC messages was also varied to examine the influence of time pressure in voice, data link, and mixed ATC environments. For messages sent via voice, transaction times were lengthened in the mixed media environment for closely spaced messages. The type of environment did not affect data link times. However, messages times were lengthened in both single and mixed-modality environments under time pressure. Closely spaced messages also increased the number of requests for clarification for voice messages in the mixed environment and review menu use for data link messages. Results indicated that when time pressure is introduced, the mix of voice and data link does not necessarily capitalize on the advantages of both media. These findings emphasize the need to develop procedures for managing communication in mixed voice and data link environments.

  12. Automatic Speech Recognition Systems for the Evaluation of Voice and Speech Disorders in Head and Neck Cancer

    Directory of Open Access Journals (Sweden)

    Andreas Maier

    2010-01-01

    Full Text Available In patients suffering from head and neck cancer, speech intelligibility is often restricted. For assessment and outcome measurements, automatic speech recognition systems have previously been shown to be appropriate for objective and quick evaluation of intelligibility. In this study we investigate the applicability of the method to speech disorders caused by head and neck cancer. Intelligibility was quantified by speech recognition on recordings of a standard text read by 41 German laryngectomized patients with cancer of the larynx or hypopharynx and 49 German patients who had suffered from oral cancer. The speech recognition provides the percentage of correctly recognized words of a sequence, that is, the word recognition rate. Automatic evaluation was compared to perceptual ratings by a panel of experts and to an age-matched control group. Both patient groups showed significantly lower word recognition rates than the control group. Automatic speech recognition yielded word recognition rates which complied with experts' evaluation of intelligibility on a significant level. Automatic speech recognition serves as a good means with low effort to objectify and quantify the most important aspect of pathologic speech—the intelligibility. The system was successfully applied to voice and speech disorders.

    2009-01-01

    In this paper we present the first step in a larger series of experiments for the induction of predicate/argument structures. The structures that we are inducing are very similar to the conceptual structures that are used in Frame Semantics (such as FrameNet). Those structures are called messages and they were previously used in the context of a multi-document summarization system of evolving events. The series of experiments that we are proposing are essentially composed from two stages. In the first stage we are trying to extract a representative vocabulary of words. This vocabulary is later used in the second stage, during which we apply to it various clustering approaches in order to identify the clusters of predicates and arguments--or frames and semantic roles, to use the jargon of Frame Semantics. This paper presents in detail and evaluates the first stage.

    2007-05-01

    This study concerns speaking voice quality in a group of male teachers (n = 35) and male actors (n = 36), as the purpose was to investigate normal and supranormal voices. The goal was the development of a method of valid perceptual evaluation for normal to supranormal and resonant voices. The voices (text reading at two loudness levels) had been evaluated by 10 listeners, for 15 vocal characteristics using VA scales. In this investigation, the results of an exploratory factor analysis of the vocal characteristics used in this method are presented, reflecting four dimensions of major importance for normal and supranormal voices. Special emphasis is placed on the effects on voice quality of a change in the loudness variable, as two loudness levels are studied. Furthermore, the vocal characteristics Sonority and Ringing voice quality are paid special attention, as the essence of the term "resonant voice" was a basic issue throughout a doctoral dissertation where this study was included.

    Full Text Available Voice biometric is an easy and cost effective biometric technique which requires minimalistic hardware and software complexity. General voice biometric needs a voice phrase by user which is processed with Mel Filter and Vector Quantized features are extracted. Vector quantization reduces the codebook size but decreases the accuracy of recognition. Therefore we propose a voice biometric system where voice file's non quantized code books are matched with spoken phrase. In order to ensure security to such direct voice sample we embed the voice file in a randomly selected image using DWT technique. Imposters are exposed to only images and are unaware of the voice files. We show that the technique produces better efficiency in comparison to VQ based technique.

    Since ancient times, steganography, the art of concealing information, has largely relied on secret inks as a tool for hiding messages. However, as the methods for detecting these inks improved, the use of simple and accessible chemicals as a means to secure communication was practically abolished. Here, we describe a method that enables one to conceal multiple different messages within the emission spectra of a unimolecular fluorescent sensor. Similar to secret inks, this molecular-scale messaging sensor (m-SMS) can be hidden on regular paper and the messages can be encoded or decoded within seconds using common chemicals, including commercial ingredients that can be obtained in grocery stores or pharmacies. Unlike with invisible inks, however, uncovering these messages by an unauthorized user is almost impossible because they are protected by three different defence mechanisms: steganography, cryptography and by entering a password, which are used to hide, encrypt or prevent access to the information, respectively.

    Introduction Tuberculosis (TB) is a notifiable disease and health care providers are required to notify every TB case to local authorities. We conducted a pilot study to determine the usefulness and feasibility of mobile interface in TB notification (MITUN) voice based system for notification of TB cases by private medical practitioners. Methodology The study was conducted during September 2013 to October 2014 in three zones of Chennai, an urban setting in South India. Private clinics wherein services are provided by single private medical practitioners were approached. The steps involved in MITUN included: Registration of the practitioners and notification of TB cases by them through voice interactions. Pre and post-intervention questionnaires were administered to collect information on TB notification practices and feasibility of MITUN after an implementation period of 6 months. Results A total of 266 private medical practitioners were approached for the study. Of them, 184 (69%) participated in the study; of whom 11 (6%) practitioners used MITUN for TB notification. Reasons for not using MITUN include lack of time, referral of patients to government facility, issues related to patient confidentiality and technical problems. Suggestions for making mobile phone based TB notification process user-friendly included reducing call duration, including only crucial questions and using missed call or SMS options. Conclusion The performance (feasibility and usefulness) of MITUN voice based system for TB notification in the present format was sub-optimal. Perceived problems, logistical and practical issues preclude scale–up of notification of TB by private practitioners. PMID:26376197

  12. Self-regulating Message Throughput in Enterprise Messaging Servers – A Feedback Control Solution

    Directory of Open Access Journals (Sweden)

    Ravi Kumar G

    2012-01-01

    Full Text Available Enterprise Messaging is a very popular message exchange concept in asynchronous distributed computing environments. The Enterprise Messaging Servers are heavily used in building business critical Enterprise applications such as Internet based Order processing systems, pricing distribution of B2B, geographically dispersed enterprise applications. It is always desirable that Messaging Servers exhibit high performance to meet the Service Level Agreements (SLAs. There are investigations in this area of managing the performance of the distributed computing systems in different ways such as the IT administrators configuring and tuning the Messaging Servers parameters, implement complex conditional programming to handle the workload dynamics. But in practice it is extremely difficult to handle such dynamics of changing workloads in order to meet the performance requirements. Additionally it is challenging to cater to the future resource requirements based on the future workloads. Though there have been attempts to self-regulate the performance of Enterprise Messaging Servers, there is a limited investigation done in exploring feedback control systems theory in managing the Messaging Servers performance. We propose an adaptive control based solution to not only manage the performance of the servers to meet SLAs but also to pro-actively self-regulate the performance such that the Messaging Servers are capable to meet the current and future workloads. We implemented and evaluated our solution and observed that the control theory based solution will improve the performance of Enterprise Messaging Servers significantly.

    The study aimed to determine the differences in responses to the Voice Handicap Index (VHI-10) between singers and nonsingers and to evaluate the ranked order differences of the VHI-10 statements for both groups. The VHI-10 was modified to include statements related to the singing voice for comparison to the original VHI-10. Thirty-five nonsingers with documented voice disorders responded to the VHI-10. A second group, consisting of 35 singers with voice complaints, responded to the VHI-10 with three statements added specifically addressing the singing voice. Data from both groups were analyzed in terms of overall subject self-rating of voice handicap and the rank order of statements from least to most important. The difference between the mean VHI-10 for the singers and nonsingers was not statistically significant, thus, supporting the validity of the VHI-10. However, the 10 statements were ranked differently in terms of their importance by both groups. In addition, when three statements related specifically to the singing voice were substituted in the original VHI-10, the singers judged their voice problem to be more severe than when using the original VHI-10. The type of statements used to assess self-perception of voice handicap may be related to the subject population. Singers with voice problems do not rate their voices to be more handicapped than nonsingers unless statements related specifically to singing are included.

    A method for passing messages in a parallel computer system constructed as a plurality of compute nodes interconnected as a network where each compute node includes a DMA engine but includes only a limited number of byte counters for tracking a number of bytes that are sent or received by the DMA engine, where the byte counters may be used in shared counter or exclusive counter modes of operation. The method includes using rendezvous protocol, a source compute node deterministically sending a request to send (RTS) message with a single RTS descriptor using an exclusive injection counter to track both the RTS message and message data to be sent in association with the RTS message, to a destination compute node such that the RTS descriptor indicates to the destination compute node that the message data will be adaptively routed to the destination node. Using one DMA FIFO at the source compute node, the RTS descriptors are maintained for rendezvous messages destined for the destination compute node to ensure proper message data ordering thereat. Using a reception counter at a DMA engine, the destination compute node tracks reception of the RTS and associated message data and sends a clear to send (CTS) message to the source node in a rendezvous protocol form of a remote get to accept the RTS message and message data and processing the remote get (CTS) by the source compute node DMA engine to provide the message data to be sent.

    Full Text Available Speech recognition is the ability of a machine or program to convert spoken words into its equivalent text form. Nowadays, most recognition systems use Hidden Markov Models for modeling the spoken utterances. In this paper we have implemented two speaker independent speech recognition systems which include all the words required for dialing a phone. The systems contain 42 words including digits from zero to nine and also include names of 20 persons. A total of 16,800 utterances have been used for training each system. The two systems are able to recognize continuous speech and it is implemented with the help of monophones and triphones using HTK. Experimental results show an accuracy of 74.11% for monophones based models and 93.77% for triphones based models.

    A model-based, distributed architecture integrates diverse components in a system designed for lunar and planetary surface operations: spacesuit biosensors, cameras, GPS, and a robotic assistant. The system transmits data and assists communication between the extra-vehicular activity (EVA) astronauts, the crew in a local habitat, and a remote mission support team. Software processes ("agents"), implemented in a system called Brahms, run on multiple, mobile platforms, including the spacesuit backpacks, all-terrain vehicles, and robot. These "mobile agents" interpret and transform available data to help people and robotic systems coordinate their actions to make operations more safe and efficient. Different types of agents relate platforms to each other ("proxy agents"), devices to software ("comm agents"), and people to the system ("personal agents"). A state-of-the-art spoken dialogue interface enables people to communicate with their personal agents, supporting a speech-driven navigation and scheduling tool, field observation record, and rover command system. An important aspect of the engineering methodology involves first simulating the entire hardware and software system in Brahms, and then configuring the agents into a runtime system. Design of mobile agent functionality has been based on ethnographic observation of scientists working in Mars analog settings in the High Canadian Arctic on Devon Island and the southeast Utah desert. The Mobile Agents system is developed iteratively in the context of use, with people doing authentic work. This paper provides a brief introduction to the architecture and emphasizes the method of empirical requirements analysis, through which observation, modeling, design, and testing are integrated in simulated EVA operations.

    Mages, Keith C

    2011-01-01

    This article examines the inspiration, construction, and meaning of the Bellevue Classification System (BCS), created during the 1930s for use in the Bellevue School of Nursing Library. Nursing instructor Ann Doyle, with assistance from librarian Mary Casamajor, designed the BCS after consulting with library leaders and examining leading contemporary classification systems, including the Dewey Decimal Classification and Library of Congress, Ballard, and National Health Library classification systems. A close textual reading of the classes, subclasses, and subdivisions of these classification systems against those of the resulting BCS, reveals Doyle's belief that the BCS was created not only to organize the literature, but also to promote the burgeoning intellectualism and professionalism of early twentieth-century American nursing.

  20. Engineered cell-cell communication via DNA messaging

    2012-09-01

    Full Text Available Abstract Background Evolution has selected for organisms that benefit from genetically encoded cell-cell communication. Engineers have begun to repurpose elements of natural communication systems to realize programmed pattern formation and coordinate other population-level behaviors. However, existing engineered systems rely on system-specific small molecules to send molecular messages among cells. Thus, the information transmission capacity of current engineered biological communication systems is physically limited by specific biomolecules that are capable of sending only a single message, typically “regulate transcription.” Results We have engineered a cell-cell communication platform using bacteriophage M13 gene products to autonomously package and deliver heterologous DNA messages of varying lengths and encoded functions. We demonstrate the decoupling of messages from a common communication channel via the autonomous transmission of various arbitrary genetic messages. Further, we increase the range of engineered DNA messaging across semisolid media by linking message transmission or receipt to active cellular chemotaxis. Conclusions We demonstrate decoupling of a communication channel from message transmission within engineered biological systems via the autonomous targeted transduction of user-specified heterologous DNA messages. We also demonstrate that bacteriophage M13 particle production and message transduction occurs among chemotactic bacteria. We use chemotaxis to improve the range of DNA messaging, increasing both transmission distance and communication bit rates relative to existing small molecule-based communication systems. We postulate that integration of different engineered cell-cell communication platforms will allow for more complex spatial programming of dynamic cellular consortia.

    2011-01-01

    Recent studies have shown strong correlation between social networking data and national influenza rates. We expanded upon this success to develop an automated text mining system that classifies Twitter messages in real time into six syndromic categories based on key terms from a public health ontology. 10-fold cross validation tests were used to compare Naive Bayes (NB) and Support Vector Machine (SVM) models on a corpus of 7431 Twitter messages. SVM performed better than NB on 4 out of 6 syndromes. The best performing classifiers showed moderately strong F1 scores: respiratory = 86.2 (NB); gastrointestinal = 85.4 (SVM polynomial kernel degree 2); neurological = 88.6 (SVM polynomial kernel degree 1); rash = 86.0 (SVM polynomial kernel degree 1); constitutional = 89.3 (SVM polynomial kernel degree 1); hemorrhagic = 89.9 (NB). The resulting classifiers were deployed together with an EARS C2 aberration detection algorithm in an experimental online system.

    The objectives of this study were to describe singing voice therapy (SVT), describe referred patient characteristics, and document the outcomes of SVT. Retrospective. Records of patients receiving SVT between June 2008 and June 2013 were reviewed (n = 51). All diagnoses were included. Demographic information, number of SVT sessions, and symptom severity were retrieved from the medical record. Symptom severity was measured via the 10-item Singing Voice Handicap Index (SVHI-10). Treatment outcome was analyzed by diagnosis, history of previous training, and SVHI-10. SVHI-10 scores decreased following SVT (mean change = 11, 40% decrease) (P singing lessons (n = 10) also completed an average of three SVT sessions. Primary muscle tension dysphonia (MTD1) and benign vocal fold lesion (lesion) were the most common diagnoses. Most patients (60%) had previous vocal training. SVHI-10 decrease was not significantly different between MTD and lesion. This is the first outcome-based study of SVT in a disordered population. Diagnosis of MTD or lesion did not influence treatment outcomes. Duration of SVT was short (approximately three sessions). Voice care providers are encouraged to partner with a singing voice therapist to provide optimal care for the singing voice. This study supports the use of SVT as a tool for the treatment of singing voice disorders. 4 Laryngoscope, 126:2546-2551, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

  5. Quantum interactive proofs with short messages

    Beigi, Salman; Watrous, John

    2010-01-01

    This paper considers three variants of quantum interactive proof systems in which short (meaning logarithmic-length) messages are exchanged between the prover and verifier. The first variant is one in which the verifier sends a short message to the prover, and the prover responds with an ordinary, or polynomial-length, message; the second variant is one in which any number of messages can be exchanged, but where the combined length of all the messages is logarithmic; and the third variant is one in which the verifier sends polynomially many random bits to the prover, who responds with a short quantum message. We prove that in all of these cases the short messages can be eliminated without changing the power of the model, so the first variant has the expressive power of QMA and the second and third variants have the expressive power of BQP. These facts are proved through the use of quantum state tomography, along with the finite quantum de Finetti theorem for the first variant.

    Input multimodality combining speech and hand gestures has motivated numerous usability studies. Contrastingly, issues relating to the design and ergonomic evaluation of multimodal output messages combining speech with visual modalities have not yet been addressed extensively. The experimental study presented here addresses one of these issues. Its aim is to assess the actual efficiency and usability of oral system messages including brief spatial information for helping users to locate objects on crowded displays rapidly. Target presentation mode, scene spatial structure and task difficulty were chosen as independent variables. Two conditions were defined: the visual target presentation mode (VP condition) and the multimodal target presentation mode (MP condition). Each participant carried out two blocks of visual search tasks (120 tasks per block, and one block per condition). Scene target presentation mode, scene structure and task difficulty were found to be significant factors. Multimodal target presenta...

    Full Text Available Mobile messaging is evolving beyond SMS (Short Message Service text messaging with the introduction of MMS (Multimedia Messaging Service. In the past, such a scheme is used for peer-to-peer communication. Messages are generally displayed on a cellular phone with a limited-sized screen. However, such a visualizing process is not suitable to broadcast real-time SMS/MMS messages to people in public. To facilitate the instancy and publicity, we develop a real-time information aggregator—Visualizing SMS and MMS Messages System (VSMMS—to realize the concept by integrating SMS and MMS messaging over GSM/GPRS/UMTS onto a remote display device. The device exhibits messages on a larger display device in public. VSMMS features a revolutionized variation of mass media broadcasting. In this paper, we practically illustrate how to design and implement VSMMS and use a M/M/1 model to conduct a theoretical analysis about the message delay in the system queue. Meanwhile, we make an empirical performance evaluation about the message transmission time over different networks.

    Full Text Available The number of messages that can be mined from online entries increases as the number of online application users increases. In Malaysia, online messages are written in mixed languages known as ‘Bahasa Rojak’. Therefore, mining opinion using natural language processing activities is difficult. This study introduces a Malay Mixed Text Normalization Approach (MyTNA and a feature selection technique based on Immune Network System (FS-INS in the opinion mining process using machine learning approach. The purpose of MyTNA is to normalize noisy texts in online messages. In addition, FS-INS will automatically select relevant features for the opinion mining process. Several experiments involving 1000 positive movies feedback and 1000 negative movies feedback have been conducted. The results show that accuracy values of opinion mining using Naïve Bayes (NB, k-Nearest Neighbor (kNN and Sequential Minimal Optimization (SMO increase after the introduction of MyTNA and FS-INS.

    Even in the best of situations, effective communication can be difficult to achieve. For those working in fields that are highly controversial and technical, where an ability to communicate effectively with the general public is fundamental to the success of a project or program, this task can be particularly onerous. This is especially true for communicators working in the nuclear arena, such as the US Department of Energy`s Yucca Mountain Site Characterization Project (YMP). Although these difficulties exist as a part of daily communications, numerous lessons have been learned that may be applicable for others in the field. A variety of factors can influence the effectiveness of communications. These include a message`s relative complexity, its salience, competing messages, verbal and nonverbal cues, and, perhaps most importantly, the role played by the news media. To communicate effectively with one`s audience, it is essential that each of these factors be considered and used to advantage.

    Ilic, Velimir M; Branimir, Todorovic T

    2009-01-01

    Message passing over factor graph can be considered as generalization of many well known algorithms for efficient marginalization of multivariate function. A specific instance of the algorithm is obtained by choosing an appropriate commutative semiring for the range of the function to be marginalized. Some examples are Viterbi algorithm, obtained on max-product semiring and forward-backward algorithm obtained on sum-product semiring. In this paper, Entropy Message Passing algorithm (EMP) is developed. It operates over entropy semiring, previously introduced in automata theory. It is shown how EMP extends the use of message passing over factor graphs to probabilistic model algorithms such as Expectation Maximization algorithm, gradient methods and computation of model entropy, unifying the work of different authors.

    1993-06-01

    Information, education, and communication (IEC) programs need to be strengthened to appeal to adolescents, who are increasingly contributing to unwanted pregnancy and are using abortion as a means of birth control. Successful IEC programs have the following characteristics: 1) established communication theories that guide development of materials; 2) a multimedia and a mass media approach to information dissemination, and 3) emphasis on visual displays. The primary emphasis should be on presentation of a concise, clear message with the appropriate visual medium. Many communication specialists in developing countries, however, lack the training to design and use effective IEC software. Designing effective messages involves a process of integrating scientific ideas with artistic appeal. The aim is to stimulate the target audience to change its behavior of life style. The message must be convincing and contain practical and useful information. The IEC Software Design Cycle focuses on analysis and diagnosis, design production, pretesting and modification, and distribution and evaluation. Each of these processes are described. Necessary before any attempt is made is obtaining data on historical, sociocultural, and demographic characteristics, economic activities, health and social services, communication infrastructure, marriage and family life patterns, and decision making systems. Focus group discussions may be used to collect information about the target group. An example is given of the process of development, in a course through the Center or African Family Studies, of a poster about premarital sex directed to 11-16 year olds. On the basis of focus group discussions, it was decided that the message would be to encourage girls to talk with their mothers about family life and premarital sex. The poster was produced with 2 school girls talking in front of the school. The evaluation yielded modifications such as including a school building that resembled actual

    Colorectal cancer screening rates are lower among African-American members of Kaiser Permanente Colorado (KPCO) than among members of other races and ethnicities. This study evaluated use of a linguistically congruent voice in interactive voice response outreach calls about colorectal cancer screening as a strategy to increase call completion and response. After an initial discussion group to assess cultural acceptability of the project, 6 focus groups were conducted with 33 KPCO African-American members. Participants heard and discussed recordings of 5 female voices reading the same segment of the standard-practice colorectal cancer message using interactive voice response. The linguistic palette included the voices of a white woman, a lightly accented Latina, and 3 African-American women. Participants strongly preferred the African-American voices, particularly two voices. Participants considered these voices the most trustworthy and reported that they would be the most effective at increasing motivation to complete an automated call. Participants supported the use of African-American voices when designing outgoing automated calls for African Americans because the sense of familiarity engendered trust among listeners. Participants also indicated that effective automated messages should provide immediate clarity of purpose; explain why the issue is relevant to African Americans; avoid sounding scripted; emphasize that the call is for the listener's benefit only; sound personable, warm, and positive; and not create fear among listeners. Establishing linguistic congruence between African Americans and the voices used in automated calls designed to reach them may increase the effectiveness of outreach efforts.

    Zhang, Pan; Zdeborová, Lenka; Zecchina, Riccardo

    2012-01-01

    We introduce two types of message passing algorithms for quantified Boolean formulas (QBF). The first type is a message passing based heuristics that can prove unsatisfiability of the QBF by assigning the universal variables in such a way that the remaining formula is unsatisfiable. In the second type, we use message passing to guide branching heuristics of a Davis-Putnam Logemann-Loveland (DPLL) complete solver. Numerical experiments show that on random QBFs our branching heuristics gives robust exponential efficiency gain with respect to the state-of-art solvers. We also manage to solve some previously unsolved benchmarks from the QBFLIB library. Apart from this our study sheds light on using message passing in small systems and as subroutines in complete solvers.

    Full Text Available Menopause effects a permanent change in certain body functions, one of them being voice. Moreover, if the voice is used continuously as a part of one’s occupation, this may further impact postmenopausal voice changes. The present study investigated the impact of menopause and professional voice use, and their interaction effect, on the voice. 92 women were classified into reproductive (52 and postmenopausal (40. Each group was divided into Level II (teachers and Level IV (clerks of Koufman and Isaacson’s (1991 classification. Acoustic parameters were analyzed using the VisiPitch III software. Aerodynamic parameters were manually calculated. The VHI (Voice Handicap Index was also included to improve the face validity of the study. Results suggest that Fo, SFo and MPT reduce post menopause while NHR and VTI increase. Some changes are accelerated in teachers as compared to clerks while some are decelerated. VHI scores of teachers are significantly greater than clerks, though not significantly different across menopause. Thus the presence or absence of voice use in one’s profession differentially affects postmenopausal changes. The study has implications in improving the condition of teachers in India, developing norms for menopausal changes and modifying allowable limits for voice recognition systems in future.

    2017-01-01

    CKD patients have several features conferring on them a high risk of adverse safety events, which are defined as incidents with unintended harm related to processes of care or medications. These characteristics include impaired kidney function, polypharmacy, and frequent health system encounters. The consequences of such events in CKD can include new or prolonged hospitalization, accelerated kidney function loss, acute kidney injury, ESRD, and death. Health information technology administered via telemedicine presents opportunities for CKD patients to remotely communicate safety-related findings to providers for the purpose of improving their care. However, many CKD patients have limitations that hinder their use of telemedicine and access to the broad capabilities of health information technology. In this review, we summarize previous assessments of the pre-dialysis CKD populations' proficiency in using telemedicine modalities and describe the use of interactive voice-response system to gauge the safety phenotype of the CKD patient. We discuss the potential for expanded interactive voice-response system use in CKD to address the safety threats inherent to this population.

    Full Text Available Voice is one of the advanced features of natural evolution that differentiates human beings from other primates. The human voice is capable of conveying the thoughts into spoken words along with a subtle emotion to the tone. This extraordinary character of the voice in expressing multiple emotions is the gift of God to the human beings and helps in effective interpersonal communication. Voice generation involves close interaction between cerebral signals and the peripheral apparatus consisting of the larynx, vocal cords, and trachea. The human voice is susceptible to the hormonal changes throughout life right from the puberty until senescence. Thyroid, gonadal and growth hormones have tremendous impact on the structure and function of the vocal apparatus. The alteration of voice is observed even in physiological states such as puberty and menstruation. Astute clinical observers make out the changes in the voice and refer the patients for endocrine evaluation. In this review, we shall discuss the hormonal influence on the voice apparatus in normal and endocrine disorders.

    CONVERGENCE is a French multi-partner national project designed to gather HPC and informatics expertise to innovate in the context of running French global climate models with differing grids and at differing resolutions. Efficient and reliable execution of these models and the management and dissemination of model output are some of the complexities that CONVERGENCE aims to resolve.At any one moment in time, researchers affiliated with the Institut Pierre Simon Laplace (IPSL) climate modeling group, are running hundreds of global climate simulations. These simulations execute upon a heterogeneous set of French High Performance Computing (HPC) environments. The IPSL's simulation execution runtime libIGCM (library for IPSL Global Climate Modeling group) has recently been enhanced so as to support hitherto impossible realtime use cases such as simulation monitoring, data publication, metrics collection, simulation control, visualizations … etc. At the core of this enhancement is Prodiguer: an AMQP (Advanced Message Queue Protocol) based event driven asynchronous distributed messaging platform. libIGCM now dispatches copious amounts of information, in the form of messages, to the platform for remote processing by Prodiguer software agents at IPSL servers in Paris. Such processing takes several forms: Persisting message content to database(s); Launching rollback jobs upon simulation failure; Notifying downstream applications; Automation of visualization pipelines; We will describe and/or demonstrate the platform's: Technical implementation; Inherent ease of scalability; Inherent adaptiveness in respect to supervising simulations; Web portal receiving simulation notifications in realtime.

  20. A Development of a System Enables Character Input and PC Operation via Voice for a Physically Disabled Person with a Speech Impediment

    We have designed and implemented a PC operation support system for a physically disabled person with a speech impediment via voice. Voice operation is an effective method for a physically disabled person with involuntary movement of the limbs and the head. We have applied a commercial speech recognition engine to develop our system for practical purposes. Adoption of a commercial engine reduces development cost and will contribute to make our system useful to another speech impediment people. We have customized commercial speech recognition engine so that it can recognize the utterance of a person with a speech impediment. We have restricted the words that the recognition engine recognizes and separated a target words from similar words in pronunciation to avoid misrecognition. Huge number of words registered in commercial speech recognition engines cause frequent misrecognition for speech impediments' utterance, because their utterance is not clear and unstable. We have solved this problem by narrowing the choice of input down in a small number and also by registering their ambiguous pronunciations in addition to the original ones. To realize all character inputs and all PC operation with a small number of words, we have designed multiple input modes with categorized dictionaries and have introduced two-step input in each mode except numeral input to enable correct operation with small number of words. The system we have developed is in practical level. The first author of this paper is physically disabled with a speech impediment. He has been able not only character input into PC but also to operate Windows system smoothly by using this system. He uses this system in his daily life. This paper is written by him with this system. At present, the speech recognition is customized to him. It is, however, possible to customize for other users by changing words and registering new pronunciation according to each user's utterance.

    Media messages can facilitate the delivery of accurate information related to HIV and sexually transmitted infection. This study's purpose was to examine preexisting media campaigns from the iMPPACS study to assess age-, gender-, and culturally appropriate components identified by African American females who attend historically Black colleges/universities. In 3 separate focus group sessions, 31 Black female college students (M age = 20) viewed 4 vignettes and heard 3 audio-only clips, then ranked and commented on them based on perceived satisfaction with HIV prevention content and appropriateness of delivery. Conventional qualitative analysis using NVivo software was performed until saturation of content was achieved and themes derived. Six major themes emerged and were designated as (a) social media; (b) mirror image; (c) visually dynamic advertisements; (d) the real world; (e) people, place, things; and (f) HIV knowledge. Visually stimulating content (i.e., graphics) was found to be most appealing in marketing HIV prevention, with brief monologue/dialogue from scenarios that resemble daily life. Socially and culturally relevant HIV prevention messages are important to Black college female students. Participants recommended creating short audiovisual messages that encompass familiar contexts like dorm rooms and appealing graphics for HIV health promotion messages, such as emojis. Future audio-only prevention advertisements for this population should use recognizable voices (e.g., celebrities). Finally, messaging should be promoted on open and closed circuit social media platforms.

In this new scenario, classical identification methods (such fingerprints or face recognition have been forcedly replaced by alternative biometric characteristics such as voice, as sometimes this is the only feature available. Through the present paper, a new methodology to characterize speakers will be shown. This methodology is benefiting from the advances achieved during the last years in understanding and modelling voice production. The paper hypothesizes that a gender dependent characterization of speakers combined with the use of a new set of biometric parameters extracted from the components resulting from the deconstruction of the voice into its glottal source and vocal tract estimates, will enhance recognition rates when compared to classical approaches. A general description about the main hypothesis and the methodology followed to extract gender-dependent extended biometric parameters are given. Experimental validation is carried out both on a highly controlled acoustic condition database, and on a mobile phone network recorded under non-controlled acoustic conditions.

  11. Wavelet adaptation for automatic voice disorders sorting.

    Erfanian Saeedi, Nafise; Almasganj, Farshad

    2013-07-01

    Early diagnosis of voice disorders and abnormalities by means of digital speech processing is a subject of interest for many researchers. Various methods are introduced in the literature, some of which are able to extensively discriminate pathological voices from normal ones. Voice disorders sorting, on the other hand, has received less attention due to the complexity of the problem. Although, previous publications show satisfactory results in classifying one type of disordered voice from normal cases, or two different types of abnormalities from each other, no comprehensive approach for automatic sorting of vocal abnormalities has been offered yet. In this paper, a solution for this problem is suggested. We create a powerful wavelet feature extraction approach, in which, instead of standard wavelets, adaptive wavelets are generated and applied to the voice signals. Orthogonal wavelets are parameterized via lattice structure and then, the optimal parameters are investigated through an iterative process, using the genetic algorithm (GA). GA is guided by the classifier results. Based on the generated wavelet, a wavelet-filterbank is constructed and the voice signals are decomposed to compute eight energy-based features. A support vector machine (SVM) then classifies the signals using the extracted features. Experimental results show that six various types of vocal disorders: paralysis, nodules, polyps, edema, spasmodic dysphonia and keratosis are fully sorted via the proposed method. This could be a successful step toward sorting a larger number of abnormalities associated with the vocal system. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2005-01-01

    Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.

    2007-12-01

    The Puerto Rico Seismic Network (PRSN) has historically provided locations and magnitudes for earthquakes in the Puerto Rico and Virgin Islands (PRVI) region. PRSN is the reporting authority for the region bounded by latitudes 17.0N to 20.0N, and longitudes 63.5W to 69.0W. The main objective of the PRSN is to record, process, analyze, provide information and research local, regional and teleseismic earthquakes, providing high quality data and information to be able to respond to the needs of the emergency management, academic and research communities, and the general public. The PRSN runs Earthworm software (Johnson et al, 1995) to acquire and write waveforms to disk for permanent archival. Automatic locations and alerts are generated for events in Puerto Rico, the Intra America Seas, and the Atlantic by the EarlyBird system (Whitmore and Sokolowski, 2002), which monitors PRSN stations as well as some 40 additional stations run by networks operating in North, Central and South America and other sites in the Caribbean. PRDANIS (Puerto Rico Data Analysis and Information System) software, developed by PRSN, supports manual locations and analyst review of automatic locations of events within the PRSN area of responsibility (AOR), using all the broadband, strong-motion and short-period waveforms Rapidly available information regarding the geographic distribution of ground shaking in relation to the population and infrastructure at risk can assist emergency response communities in efficient and optimized allocation of resources following a large earthquake. The ShakeMap system developed by the USGS provides near real-time maps of instrumental ground motions and shaking intensity and has proven effective in rapid assessment of the extent of shaking and potential damage after significant earthquakes (Wald, 2004). In Northern and Southern California, the Pacific Northwest, and the states of Utah and Nevada, ShakeMaps are used for emergency planning and response, loss

Nowadays, we have useful assessments in health system that are refered for numerous clinical decisions. In this way, this investigation compares clinician and patient perception in dysphonic and normal voiced for first time.Methods: This study was carried out on 30 dysphonic and 30 subjects with normal voice. Their age, sex and job were same. In two groups, Consensus Auditory – Perceptual Evaluation of Voice (CAPE-V was used for evaluation of clinician perception and Voice Handicap Index - 30 (VHI-30 for assessment of patient perception. After collecting data, they were analyzed by Mann- witney and Wilcoxon tests.Results: The research revealed that mean of total and each section score of VHI-30 have significant difference between dysphonic and control group (p<0.01. Comparison of total and every parameter score of CAPE-V and speed also indicated significant difference between two groups (p<0.01. Study of reliability shows weak reliability (r=0.34 between clinician and patient perception of voice in dysphonics.Conclusion: Dysphonic patients percept their voice problem different and severe rather than clinicians that shows physical, psychological and social affects of dysphonia. This research confirms that patient – based assessment of voice is necessary to be part of common assessments of dysphonia.

    Full Text Available Abstract: As a product of mass media, news photograph is an image which provides the viewers with a valuable source of information and news story. All events captured in photographs turn into a news photo. Besides covering the news with fact, news photographs do not only have surface meanings, but also deeper meanings to be interpreted by each viewer. The phenomenon of demonstration, particularly the massive demonstration in Egypt in 2011, offers a good chance to discover how visual messages have been presented to guide interpretation of foreign news events. Principally, demonstration is an expression of the people’s voices, and thus, their voices are related closely with their demands, grievances and wishes related to the new government. Here, the photographs are able to portray and reflect the people’s voices through the compositions and contents (meanings involved in the photos. This study is aimed at discovering the portrayal of the voice of the people (the protesters in the news photographs of the Indonesian online newspaper, The Jakarta Globe. The data consist of 15 news photographs taken from The Jakarta Globe online newspaper published in January – October 2011. The study employs qualitative method framed with semiotic analysis using Roland Barthes’ theory of orders of signification and photographic message. The results of the study show that The Jakarta Globe visually constructs this event (demonstration by focusing on the human action (the protesters. Thus, the voice of the people is portrayed in the photo subjects (the protesters and the included objects of the photo. Meanwhile, the technical aspects of the photos play a meaningful role in emerging the portrayal of the people’s voice. There are four voices revealed by the people in the 15 photographs, namely the voice of freedom, the voice of peace, the voice of justice and the voice of human rights. The photo text including headlines and captions also interact with

    Telephone-based interactive voice response (IVR) systems could be an effective tool for promotion of physical activity among older women. To test IVR feasibility, we enrolled 30 older women in a 10-week physical activity intervention designed around National Institute on Aging (NIA) Go4Life® educational materials with IVR coaching. Participants (mean age = 76 years) significantly increased physical activity by a mean 79 ± 116 (SD) minutes/week (p < .001). Participants reported that the Go4Life® materials, pedometer, and IVR coaching (70% reported easy technology) were useful tools for change. This pilot study demonstrates IVR acceptability as an evidence-based physical activity program for older women.

    Barr, Dale J; Jackson, Laura; Phillips, Isobel

    2014-02-01

    We propose that hearing a proper name (e.g., Kevin) in a particular voice serves as a compound memory cue that directly activates representations of a mutually known target person, often permitting reference resolution without any complex computation of shared knowledge. In a referential communication study, pairs of friends played a communication game, in which we monitored the eyes of one friend (the addressee) while he or she sought to identify the target person, in a set of four photos, on the basis of a name spoken aloud. When the name was spoken by a friend, addressees rapidly identified the target person, and this facilitation was independent of whether the friend was articulating a message he or she had designed versus one from a third party with whom the target person was not shared. Our findings suggest that the comprehension system takes advantage of regularities in the environment to minimize effortful computation about who knows what.

    Methods, systems, and products are disclosed for broadcasting a message in a parallel computer. The parallel computer includes a plurality of compute nodes connected together using a data communications network. The data communications network optimized for point to point data communications and is characterized by at least two dimensions. The compute nodes are organized into at least one operational group of compute nodes for collective parallel operations of the parallel computer. One compute node of the operational group assigned to be a logical root. Broadcasting a message in a parallel computer includes: establishing a Hamiltonian path along all of the compute nodes in at least one plane of the data communications network and in the operational group; and broadcasting, by the logical root to the remaining compute nodes, the logical root's message along the established Hamiltonian path.

  13. Implicit multisensory associations influence voice recognition.

    Directory of Open Access Journals (Sweden)

    2006-10-01

    Full Text Available Natural objects provide partially redundant information to the brain through different sensory modalities. For example, voices and faces both give information about the speech content, age, and gender of a person. Thanks to this redundancy, multimodal recognition is fast, robust, and automatic. In unimodal perception, however, only part of the information about an object is available. Here, we addressed whether, even under conditions of unimodal sensory input, crossmodal neural circuits that have been shaped by previous associative learning become activated and underpin a performance benefit. We measured brain activity with functional magnetic resonance imaging before, while, and after participants learned to associate either sensory redundant stimuli, i.e. voices and faces, or arbitrary multimodal combinations, i.e. voices and written names, ring tones, and cell phones or brand names of these cell phones. After learning, participants were better at recognizing unimodal auditory voices that had been paired with faces than those paired with written names, and association of voices with faces resulted in an increased functional coupling between voice and face areas. No such effects were observed for ring tones that had been paired with cell phones or names. These findings demonstrate that brief exposure to ecologically valid and sensory redundant stimulus pairs, such as voices and faces, induces specific multisensory associations. Consistent with predictive coding theories, associative representations become thereafter available for unimodal perception and facilitate object recognition. These data suggest that for natural objects effective predictive signals can be generated across sensory systems and proceed by optimization of functional connectivity between specialized cortical sensory modules.

    Full Text Available Objectives: When a person speaks, voice problems usually include pain or discomfort and/or difficulties in terms of the pitch, the loudness and the quality of the voice. When patients with voice problems induced by stroke, Parkinson’s disease, and systemic diseases involving the voice are examined, generally, of the Four Diagnoses (四診, a Diagnosis of Hearing can be used in current Korean medicine. The effects of acupuncture and herb medicine on voice problems have been reported for over 20 years. However, when it comes to improvements, objective and subjective evaluation methods need to be explained. Methods: Subjective methods for evaluating voice were studied through a literature search of old medicinal books containing Korean medicine diagnostics, and an objective evaluation method using Praat software is presented. Results: Korean medicine doctors analyze the patient’s voice in clinical settings unconsciously on a daily basis. However, most voice diagnoses depend on the doctor’s subjective evaluation. Voice qualities can be evaluated by using the Eight Principles (八綱, including Yin-Yang; the Five Elements (Phases; the Grade, Roughness, Breathy, Asthenic, Strained (GRBAS score, and the Visual Analogue Scale (VAS as subjective methods, and an acoustic analysis using the Praat program can be used as an objective method. Conclusion: A more complete voice examination can be achieved by using subjective and objective methods at the same time. For an objective explanation and management of patient’s voice problems or systemic disorders, an objective method should be used in Korean medicine, which already has many subjective diagnostic methods. More research needs to be conducted, and more clinical evidence needs to be collected in the future.

    Social interaction promotes the spread of values, attitudes, and behaviors. Here, we report on neural responses to ideas that are destined to spread. We scanned message communicators using functional MRI during their initial exposure to the to-be-communicated ideas. These message communicators then had the opportunity to spread the messages and their corresponding subjective evaluations to message recipients outside the scanner. Successful ideas were associated with neural responses in the communicators' mentalizing systems and reward systems when they first heard the messages, prior to spreading them. Similarly, individuals more able to spread their own views to others produced greater mentalizing-system activity during initial encoding. Unlike prior social-influence studies that focused on the individuals being influenced, this investigation focused on the brains of influencers. Successful social influence is reliably associated with an influencer-to-be's state of mind when first encoding ideas.

    Event Driven Messaging with Role-Based Subscriptions (EDM-RBS) is a framework integrated into the Service Management Database (SMDB) to allow for role-based and subscription-based delivery of synchronous and asynchronous messages over JMS (Java Messaging Service), SMTP (Simple Mail Transfer Protocol), or SMS (Short Messaging Service). This allows for 24/7 operation with users in all parts of the world. The software classifies messages by triggering data type, application source, owner of data triggering event (mission), classification, sub-classification and various other secondary classifying tags. Messages are routed to applications or users based on subscription rules using a combination of the above message attributes. This program provides a framework for identifying connected users and their applications for targeted delivery of messages over JMS to the client applications the user is logged into. EDMRBS provides the ability to send notifications over e-mail or pager rather than having to rely on a live human to do it. It is implemented as an Oracle application that uses Oracle relational database management system intrinsic functions. It is configurable to use Oracle AQ JMS API or an external JMS provider for messaging. It fully integrates into the event-logging framework of SMDB (Subnet Management Database).

    Over the last few decades, reproductive medicine has observed an improvement in the management and outcome of pregnancy in connective tissue diseases, such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). However, pregnancy and related issues remain a challenge in these patients. In routine clinical practice, health professionals dealing with SLE and APS need to consider the numerous aspects of the reproductive life of their patients, such as pregnancy, family planning, fertility, contraception, cancer surveillance, and menopause. The new European League Against Rheumatism recommendations for women's health and family planning reflect the need for a novel approach to communication in the patient-physician relationship. Preconception counseling is essential to ensure optimal pregnancy outcomes through a careful risk stratification involving disease activity, organ involvement, autoantibody profile, use of drugs, and previous pregnancy outcomes, as well as to ensure better preventive and therapeutic strategies to limit complications. In patients with stable/inactive disease and low risk of thrombosis, adequate hormonal contraception and menopausal replacement therapy should be recommended. Assisted reproductive techniques can be safely used in these patients, but anticoagulation or low-dose aspirin (or both) should be added in those with positive antiphospholipid antibody titers. All menstruating women should be counseled on the possibility to preserve fertility with gonadotropin- ‑releasing hormone analogues if receiving alkylating agents. Strict clinical, serological, laboratory, and multidisciplinary monitoring during pregnancy is mandatory to early recognize and effectively treat disease flares or obstetric complications. Doppler ultrasonography and fetal biometry should be regularly performed, especially in the second and third trimesters. Physicians should recommend screening for cervical dysplasia related to human papillomavirus

    Full Text Available The inner voice- we all know what it is because we all have it and use it when we are thinking or reading, for example. Little work has been done on it in our field, with the notable exception of Brian Tomlinson, but presumably it must be a cognitive phenomenon which is of great importance in thinking, language learning, and reading in a foreign language. The inner voice will be discussed as a cognitive psychological phenomenon associated with short-term memory, and distinguished from the inner ear. The process of speech recoding will be examined (the process of converting written language into the inner voice and the importance of developing the inner voice, as a means of both facilitating the production of a new language and enhancing the comprehension of a text in a foreign language, will be emphasized. Finally, ways of developing the inner voice in beginning and intermediate readers of a foreign language will be explored and recommended.

    Changes in speech have been suggested as sensitive and valid measures of depression and mania in bipolar disorder. The present study aimed at investigating (1) voice features collected during phone calls as objective markers of affective states in bipolar disorder and (2) if combining voice features with automatically generated objective smartphone data on behavioral activities (for example, number of text messages and phone calls per day) and electronic self-monitored data (mood) on illness activity would increase the accuracy as a marker of affective states. Using smartphones, voice features, automatically generated objective smartphone data on behavioral activities and electronic self-monitored data were collected from 28 outpatients with bipolar disorder in naturalistic settings on a daily basis during a period of 12 weeks. Depressive and manic symptoms were assessed using the Hamilton Depression Rating Scale 17-item and the Young Mania Rating Scale, respectively, by a researcher blinded to smartphone data. Data were analyzed using random forest algorithms. Affective states were classified using voice features extracted during everyday life phone calls. Voice features were found to be more accurate, sensitive and specific in the classification of manic or mixed states with an area under the curve (AUC)=0.89 compared with an AUC=0.78 for the classification of depressive states. Combining voice features with automatically generated objective smartphone data on behavioral activities and electronic self-monitored data increased the accuracy, sensitivity and specificity of classification of affective states slightly. Voice features collected in naturalistic settings using smartphones may be used as objective state markers in patients with bipolar disorder.

    2017-01-01

    Historically, tremendous effort has been put into processing and displaying mission health and safety telemetry data; and relatively little attention has been paid to extracting information from missions time-tagged event log messages. Todays missions may log tens of thousands of messages per day and the numbers are expected to dramatically increase as satellite fleets and constellations are launched, as security monitoring continues to evolve, and as the overall complexity of ground system operations increases. The logs may contain information about orbital events, scheduled and actual observations, device status and anomalies, when operators were logged on, when commands were resent, when there were data drop outs or system failures, and much much more. When dealing with distributed space missions or operational fleets, it becomes even more important to systematically analyze this data. Several advanced information systems technologies make it appropriate to now develop analytic capabilities which can increase mission situational awareness, reduce mission risk, enable better event-driven automation and cross-mission collaborations, and lead to improved operations strategies: Industry Standard for Log Messages. The Object Management Group (OMG) Space Domain Task Force (SDTF) standards organization is in the process of creating a formal standard for industry for event log messages.

  12. The Belt voice: Acoustical measurements and esthetic correlates

    Science.gov (United States)

    Bounous, Barry Urban

    This dissertation explores the esthetic attributes of the Belt voice through spectral acoustical analysis. The process of understanding the nature and safe practice of Belt is just beginning, whereas the understanding of classical singing is well established. The unique nature of the Belt sound provides difficulties for voice teachers attempting to evaluate the quality and appropriateness of a particular sound or performance. This study attempts to provide answers to the question "does Belt conform to a set of measurable esthetic standards?" In answering this question, this paper expands on a previous study of the esthetic attributes of the classical baritone voice (see "Vocal Beauty", NATS Journal 51,1) which also drew some tentative conclusions about the Belt voice but which had an inadequate sample pool of subjects from which to draw. Further, this study demonstrates that it is possible to scientifically investigate the realm of musical esthetics in the singing voice. It is possible to go beyond the "a trained voice compared to an untrained voice" paradigm when evaluating quantitative vocal parameters and actually investigate what truly beautiful voices do. There are functions of sound energy (measured in dB) transference which may affect the nervous system in predictable ways and which can be measured and associated with esthetics. This study does not show consistency in measurements for absolute beauty (taste) even among belt teachers and researchers but does show some markers with varying degrees of importance which may point to a difference between our cognitive learned response to singing and our emotional, more visceral response to sounds. The markers which are significant in determining vocal beauty are: (1) Vibrancy-Characteristics of vibrato including speed, width, and consistency (low variability). (2) Spectral makeup-Ratio of partial strength above the fundamental to the fundamental. (3) Activity of the voice-The quantity of energy being produced. (4

    2016-09-30

    Estill Voice Training (EVT) is a widely known programme for developing vocal skills based on partitioning the process of vocal production in order to reach control of specific structures in the vocal mechanism. The present retrospective small-scale exploratory study aims at reporting preliminary data about the efficacy of EVT - in terms of voice quality control on a specific vocal exercise - in contemporary commercial singers with a Certificate of Figure Proficiency (CFP). Thirty-five contemporary commercial singers (professional or semi-professional pop and rock singers) with no vocal complaints were recruited. The experimental group was composed of twenty singers who studied EVT and had a CFP. The control group was composed of fifteen singers who studied in Italian contemporary popular music institutions but were not familiar with EVT. Voice quality control was assessed through acoustic and perceptual analysis on a specific vocal exercise requiring sound pitch, perturbation and spectral energy distribution control. The acoustic analysis showed some significant differences between the two groups of singers both in sound perturbation control and spectral energy distribution control, suggesting a higher voice quality control ability for the experimental group. The perceptual evaluation confirmed a higher ability for the experimental group to produce recognizable voice qualities in this specific task. The reported preliminary results seem to suggest EVT as an effective educational system for developing voice quality control ability in contemporary commercial singers.

    Full Text Available In recent years, mobile devices have become relatively more powerful with additional features which have the capability to provide multimedia streaming. Better, faster and more reliable data storage solutions in the mobile messaging platform have become more essential with these additional improvements. The existing mobile messaging infrastructure, in particular the data storage platform has become less proficient in coping with the increased demand for its services. This demand especially in the mobile messaging area (i.e. SMS – Short Messaging Service, MMS – Multimedia Messaging Service, which may well exceeded 250,000 requests per second, means that the need to evaluate competing data management systems has become not only necessary but essential. This paper presents an evaluation of SMS and MMS platforms using different database management systems – DBMS and recommends the best data management strategies for these platforms.

    Navigation message designing with high accuracy guarantee is the key to efficient navi-gation message distribution in the global navigation satellite system (GNSS). Developing high accu-racy-aware navigation message designing algorithms is an important topic. This paper investigates the high-accuracy navigation message designing problem with the message structure unchanged. The contributions made in this paper include a heuristic that employs the concept of the estimated range deviation (ERD) to improve the existing well-known navigation message on L1 frequency (NAV) of global positioning system (GPS) for good accuracy service; a numerical analysis approximation method (NAAM) to evaluate the range error due to truncation (RET) of different navigation messages; and a basic positioning parameters designing algorithm in the limited space allocation. Based on the predicted ultra-rapid data from the ultra-rapid data from the international GPS service for geodynamic (IGU), ERDs are generated in real time for error correction. Simulations show that the algorithms developed in this paper are general and flexible, and thus are applicable to NAV improvement and other navigation message designs.

  19. Enhancement of Delivery of Warning Messages for Mobile Networks

    Full Text Available Vehicle-to-vehicle (V2V communication systems have been studied extensively in recent years by transportation experts worldwide. Such systems enable the transmission of warning messages (alarms between vehicles without additional roadside infrastructure. Thus, messages can be sent faster than through base stations. Because of these advantages, researchers worldwide are exploring how this technology can improve traffic safety. However, the various V2V schemes proposed thus far share the same problem: (1 unnecessary repetition of warning messages and (2 transmission to inapplicable respondents. This study proposes a new method for delivering V2V warning messages which reduces the redundant messages common in current schemes. Here, three schemes to deliver alarms are considered. One is blind flooding to broadcast alarms. Warning messages are routed by AODV protocol. Another is called Two Lanes. The broadcasting region of alarms is limited in two traffic lanes nearby a traffic accident only. And the last one is the proposed strategy where a warning message received by a car will be simply checked the prime number carried within the alarm header and decided whether the car is responsible to deliver it. If necessary, it will be forwarded to the next nodes. Otherwise, the redundant warning message shall be discarded to release system load and avoid to suspend other normal transmission proceeding. The results reveal that minimizing the delays caused by such redundant messages enables warnings to be sent to drivers more rapidly. Also, it prioritizes warning messages so that drivers are apprised of the most serious and dangerous traffic accidents. Moreover, another key finding in this paper is that the radii of the broadcasting coverage shall be adjusted carefully and adaptively to optimize the system performance.

    Using Gray and McNaughton's (2000) revised reinforcement sensitivity theory (r-RST), we examined the influence of personality on processing of words presented in gain-framed and loss-framed anti-speeding messages and how the processing biases associated with personality influenced message acceptance. The r-RST predicts that the nervous system regulates personality and that behaviour is dependent upon the activation of the behavioural activation system (BAS), activated by reward cues and the fight-flight-freeze system (FFFS), activated by punishment cues. According to r-RST, individuals differ in the sensitivities of their BAS and FFFS (i.e., weak to strong), which in turn leads to stable patterns of behaviour in the presence of rewards and punishments, respectively. It was hypothesised that individual differences in personality (i.e., strength of the BAS and the FFFS) would influence the degree of both message processing (as measured by reaction time to previously viewed message words) and message acceptance (measured three ways by perceived message effectiveness, behavioural intentions, and attitudes). Specifically, it was anticipated that, individuals with a stronger BAS would process the words presented in the gain-frame messages faster than those with a weaker BAS and individuals with a stronger FFFS would process the words presented in the loss-frame messages faster than those with a weaker FFFS. Further, it was expected that greater processing (faster reaction times) would be associated with greater acceptance for that message. Driver licence holding students (N=108) were recruited to view one of four anti-speeding messages (i.e., social gain-frame, social loss-frame, physical gain-frame, and physical loss-frame). A computerised lexical decision task assessed participants' subsequent reaction times to message words, as an indicator of the extent of processing of the previously viewed message. Self-report measures assessed personality and the three message

    Biosurveillance and disease surveillance systems serve different purposes. However, the richness and quality of an existing data stream and infrastructure used in biosurveillance may prove beneficial for any state-based electronic disease surveillance system, especially if an electronic laboratory data feed does not exist between a hospital and state-based system. The use of an Enterprise Application Integration(EAI) engine, such as the BioSense Integrator,will be necessary to map heterogeneous messages into standard representations, then validate and route them [1] to a disparate system. This poster illustrates the use of an existing BioSense Integrator in order to create a unified message to support the exchange of electronic lab messages necessary for reportable disease notification. An evaluation of the infrastructure for data messaging will be examined and presented, along with a cost and benefit analysis between hospital and state-based system.

    Institute of Scientific and Technical Information of China (English)

    刘进; 田晖; 周可

    2014-01-01

    Steganography based on bits-modification of speech frames is a kind of commonly used method, which targets at RTP payloads and offers covert communications over voice-over-IP (VoIP). However, direct modification on frames is often independent of the inherent speech features, which may lead to great degradation of speech quality. A novel frame-bitrate-change based steganography is proposed in this work, which discovers a novel covert channel for VoIP and introduces less distortion. This method exploits the feature of multi-rate speech codecs that the practical bitrate of speech frame is identified only by speech decoder at receiving end. Based on this characteristic, two steganography strategies called bitrate downgrading (BD) and bitrate switching (BS) are provided. The first strategy substitutes high bit-rate speech frames with lower ones to embed secret message, which introduces very low distortion in practice, and much less than other bits-modification based methods with the same embedding capacity. The second one encodes secret message bits into different types of speech frames, which is an alternative choice for supplement. The two strategies are implemented and tested on our covert communication system StegVoIP. The experiment results show that our proposed method is effective and fulfills the real-time requirement of VoIP communication.

    Full Text Available The Dining Cryptographer network (or DC-net is a privacy preserving communication protocol devised by David Chaum for anonymous message publication. A very attractive feature of DC-nets is the strength of its security, which is inherent in the protocol and is not dependent on other schemes, like encryption. Unfortunately the DC-net protocol has a level of complexity that causes it to suffer from exceptional communication overhead and implementation difficulty that precludes its use in many real-world use-cases. We have designed and created a DC-net implementation that uses a pure client-server model, which successfully avoids much of the complexity inherent in the DC-net protocol. We describe the theory of DC-nets and our pure client-server implementation, as well as the compromises that were made to reduce the protocol’s level of complexity. Discussion centers around the details of our implementation of DC-net.

    With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient-clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. Mobile texting messaging has the potential to play an important role in patient-clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication.

    2012-01-01

    A complex running system, such as the NOvA online data acquisition, consists of a large number of distributed but closely interacting components. This paper describes a generic realtime correlation analysis and event identification engine, named Message Analyzer. Its purpose is to capture run time abnormalities and recognize system failures based on log messages from participating components. The initial design of analysis engine is driven by the DAQ of the NOvA experiment. The Message Analyzer performs filtering and pattern recognition on the log messages and reacts to system failures identified by associated triggering rules. The tool helps the system maintain a healthy running state and to minimize data corruption. This paper also describes a domain specific language that allows the recognition patterns and correlation rules to be specified in a clear and flexible way. In addition, the engine provides a plugin mechanism for users to implement specialized patterns or rules in generic languages such as C++.

    Previous research using cell phones indicates that manual manipulation is not a principal component of text messaging relating driving detriment. This paper suggests that manipulation of a phone in conjunction with the cognitive need to compose the message itself co-act to contribute to driving degradation. This being so, drivers sending text messages might experience reduced interference to the driving task if the text messaging itself were assisted through the predictive T9 system. We evaluated undergraduate drivers in a simulator who drove and texted using either Assisted Text entry, via Nokia's T9 system, or unassisted entry via the multitap interface. Results supported the superiority of the T9 system over the multitap system implying that specific assistive technologies can modulate the degradation of capacity which texting tragically induces.

  13. Advanced Steganography Algorithm using Encrypted secret message

    2011-03-01

    Full Text Available In the present work the authors have introduced a new method for hiding any encrypted secret message inside a cover file. For encrypting secret message the authors have used new algorithm proposed by Nath et al(1. For hiding secret message we have used a method proposed by Nath et al(2. In MSA(1 method we have modified the idea of Play fair method into a new platform where we can encrypt or decrypt any file. We have introduced a new randomization method for generating the randomized key matrix to encrypt plain text file and to decrypt cipher text file. We have also introduced a new algorithm for encrypting the plain text multiple times. Our method is totally dependent on the random text_key which is to be supplied by the user. The maximum length of the text_key can be of 16 characters long and it may contain any character(ASCII code 0 to 255. We have developed an algorithm to calculate the randomization number and the encryption number from the given text_key. The size of the encryption key matrix is 16x16 and the total number of matrices can be formed from 16 x 16 is 256! which is quite large and hence if someone applies the brute force method then he/she has to give trail for 256! times which is quite absurd. Moreover the multiple encryption method makes the system further secured. For hiding secret message in the cover file we have inserted the 8 bits of each character of encrypted message file in 8 consecutive bytes of the cover file. We have introduced password for hiding data in the cover file. We propose that our new method could be most appropriate for hiding any file in any standard cover file such as image, audio, video files. Because the hidden message is encrypted hence it will be almost impossible for the intruder to unhide the actual secret message from the embedded cover file. This method may be the most secured method in digital water marking.

    2016-04-01

    Full Text Available Oral communication comprises one of the most important forms of social interaction. The process of learning the spoken language depends on the hearing, therefore, the total or partial loss of hearing sensitivity hinders such aspect. Digital signal processing techniques with non-invasive character are used for diagnosis, support and improvement of the voice quality of the deaf. Thus, the present study aims to propose and develop a system of analysis and correction of vocal disorders by means of visual and tactile feedback with module implemented in programmable device type FPGA (Field Programmable Gate Array. The results point to the potential of a proposed intervention as a helper for sensory substitution, being based on the monitoring and control of speech, in order to allow for the assessment and remediation by means of an electronic resource, allowing deaf individuals to obtain a support for learning the spoken language. The possibilities for improvements in communication skills observed in this study are dependent on the capability of the device together with the speech therapist, integrating therapies with the support of the family, the time and the motivation of the user, factors that cooperate for the success of this approach.

    1991-01-01

    The Philippine Food and Nutrition Program deliver priority short, simple, clear, and action filled nutrition messages in different languages and dialects to different audiences. Its 1st priority task is to promote breast feeding. It informs mothers that breast milk is the most nutritious food for infants and that it protects them from infectious diseases. The program also encourages breast feeding as long as possible. If mothers cannot breast feed, they should talk to an infant nutrition expert to help them choose the best formula and learn about proper preparation. A 4-6 month infant needs to begin eating small amounts of semisolid nutritious foods. Moreover these foods must include body building foods, such as meat and eggs, and energy providing foods, such as corn and rice. Mothers must 1st attend to food needs of infants and preschoolers since they are more likely to suffer malnutrition than older children and adults. This is especially important when they suffer from an infection. Specifically, the very young need a variety of foods each day including the vitamin and mineral rich vegetables and fruits. In fact, families should grow their own fruits and vegetables to ensure an adequate supply. Hands must be cleaned with soap and water after defecation and before preparing foods. Mothers should add fats and oils when preparing foods because they provide concentrated energy, fatty acids, and fat soluble vitamins. Pregnant mothers must consume increased amounts of fish, beans, and other body building foods as well as regulating foods (vegetables and fruits). Mothers must also space births. They should weigh children each month to monitor nutritional levels. Moreover they must pay attention to signs indicating inadequate and insufficient food intake e.g., underweight and night blindness.

  1. Classification of High Blood Pressure Persons Vs Normal Blood Pressure Persons Using Voice Analysis

    Directory of Open Access Journals (Sweden)

    Saloni

    2013-11-01

    Full Text Available The human voice is remarkable, complex and delicate. All parts of the body play some role in voice production and may be responsible for voice dysfunction. The larynx contains muscles that are surrounded by blood vessels connected to circulatory system. The pressure of blood in these vessels should be related with dynamic variation of vocal cord parameters. These parameters are directly related with acoustic properties of speech. Acoustic voice analysis can be used to characterize the pathological voices. This paper presents the classification of high blood pressure and normal with the aid of voice signal recorded from the patients. Various features have been extracted from the voice signal of healthy persons and persons suffering from high blood pressure. Simulation results show differences in the parameter values of healthy and pathological persons. Then an optimum feature vector is prepared and kmean classification algorithm was implemented for data classification. The 79% classification efficiency was obtained.

  2. Voice recognition software for clinical use.

    Korn, K

    1998-11-01

    The current generation voice recognition products truly offer the promise of voice recognition systems, that are financially and operationally acceptable for use in a health care facility. Although the initial capital outlay for the purchase of such equipment may be substantial, the long-term benefit is felt to outweigh the expense. The ability to utilize computer equipment for educational purposes and information management alone helps to rationalize the cost. In addition, it is important to remember that the Internet has become a substantial source of information which provides another functional use for this equipment. Although one can readily see the implication for such a program in clinical practice, other uses for the program should not be overlooked. Uses far beyond the writing of clinic notes and correspondence can be easily envisioned. Utilization of voice recognition software offers clinical practices the ability to produce quality printed records in a timely and cost-effective manner. After learning procedures for the selected product and appropriately formatting word processing software and printers, printed progress notes should be able to be produced in less time than traditional dictation and transcription methods. Although certain procedures and practices may need to be altered, or may preclude optimal utilization of this type of system, many advantages are apparent. It is recommended that facilities consider utilization of Voice Recognition products such as Dragon Systems Naturally Speaking Software, or at least consider a trial of this method with one of the limited-feature products, if current dictation practices are unsatisfactory or excessively costly. Free downloadable trial software or single user software can provide a reduced-cost method for trial evaluation of such products if a major commitment is not felt to be desired.

    Drews, Frank A; Yazdani, Hina; Godfrey, Celeste N; Cooper, Joel M; Strayer, David L

    2009-10-01

    This research aims to identify the impact of text messaging on simulated driving performance. In the past decade, a number of on-road, epidemiological, and simulator-based studies reported the negative impact of talking on a cell phone on driving behavior. However, the impact of text messaging on simulated driving performance is still not fully understood. Forty participants engaged in both a single task (driving) and a dual task (driving and text messaging) in a high-fidelity driving simulator. Analysis of driving performance revealed that participants in the dual-task condition responded more slowly to the onset of braking lights and showed impairments in forward and lateral control compared with a driving-only condition. Moreover, text-messaging drivers were involved in more crashes than drivers not engaged in text messaging. Text messaging while driving has a negative impact on simulated driving performance. This negative impact appears to exceed the impact of conversing on a cell phone while driving. The results increase our understanding of driver distraction and have potential implications for public safety and device development.

    This paper, to accompany a discussion panel, describes a collaborative FAA and NASA research study to determine the effect Data Communications (Data Comm) messages have on flight crew workload and eye scanning behavior in busy terminal area operations. In the Next Generation Air Transportation System Concept of Operations, for the period 2017-2022, the FAA envisions Data Comm between controllers and the flight crew to become the primary means of communicating non-time critical information. Four research conditions were defined that span current day to future equipage levels (Voice with Paper map, Data Comm with Paper map, Data Comm with Moving Map Display with ownship position displayed, Data Comm with Moving Map, ownship and taxi route displayed), and were used to create arrival and departure scenarios at Boston Logan Airport. Preliminary results for workload, situation awareness, and pilot head-up time are presented here. Questionnaire data indicated that pilot acceptability, workload, and situation awareness ratings were favorable for all of the conditions tested. Pilots did indicate that there were times during final approach and landing when they would prefer not to hear the message chime, and would not be able to make a quick response due to high priority tasks in the cockpit.

    2007-02-01

    Previous studies have demonstrated that motor control of segmental features of speech rely to some extent on sensory feedback. Control of voice fundamental frequency (F0) has been shown to be modulated by perturbations in voice pitch feedback during various phonatory tasks and in Mandarin speech. The present study was designed to determine if voice Fo is modulated in a task-dependent manner during production of suprasegmental features of English speech. English speakers received pitch-modulated voice feedback (+/-50, 100, and 200 cents, 200 ms duration) during a sustained vowel task and a speech task. Response magnitudes during speech (mean 31.5 cents) were larger than during the vowels (mean 21.6 cents), response magnitudes increased as a function of stimulus magnitude during speech but not vowels, and responses to downward pitch-shift stimuli were larger than those to upward stimuli. Response latencies were shorter in speech (mean 122 ms) compared to vowels (mean 154 ms). These findings support previous research suggesting the audio vocal system is involved in the control of suprasegmental features of English speech by correcting for errors between voice pitch feedback and the desired F0.

  20. Short-Message Quantize-Forward Network Coding

    CERN Document Server

    Kramer, Gerhard

    2011-01-01

    Compression via quantization and hashing lets relays form distributed "multi-output" nodes of a multi-input, multi-output (MIMO) system. Recent work shows that quantize-forward (QF) with long-message encoding and decoding achieves the same reliable rates as short-message compress-forward (CF). It is shown that short-message QF with backward or pipelined (sliding-window) decoding also achieve the same rates for a single-relay channel. The price paid is a more restrictive quantization that degrades performance for slow-fading channels with outage. For many relays and sources, short-message QF with backward decoding achieves the same rates as long-message QF, although again with a more restrictive quantization. Several practical advantages of short-message encoding are pointed out, e.g., reduced delay (enabling streaming) and simplified modulation (without requiring additional hashing). Furthermore, short-message encoding lets relays use decode-forward (DF) if their channel quality is good, and therefore enables...

    2013-06-01

    Full Text Available Objectives: Several studies have demonstrated a high prevalence of voice disorders in teachers, together with the personal, professional and economical consequences of the problem. Good primary prevention should be based on 3 aspects: 1 amelioration of classroom acoustics, 2 voice care programs for future professional voice users, including teachers and 3 classroom or portable amplification systems. The aim of the study was to assess the benefit obtained from the use of portable amplification systems by female primary school teachers in their occupational setting. Materials and Methods: Forty female primary school teachers attended a course about professional voice care, which comprised two theoretical lectures, each 60 min long. Thereafter, they were randomized into 2 groups: the teachers of the first group were asked to use a portable vocal amplifier for 3 months, till the end of school-year. The other 20 teachers were part of the control group, matched for age and years of employment. All subjects had a grade 1 of dysphonia with no significant organic lesion of the vocal folds. Results: Most teachers of the experimental group used the amplifier consistently for the whole duration of the experiment and found it very useful in reducing the symptoms of vocal fatigue. In fact, after 3 months, Voice Handicap Index (VHI scores in "course + amplifier" group demonstrated a significant amelioration (p = 0.003. The perceptual grade of dysphonia also improved significantly (p = 0.0005. The same parameters changed favourably also in the "course only" group, but the results were not statistically significant (p = 0.4 for VHI and p = 0.03 for perceptual grade. Conclusions: In teachers, and particularly in those with a constitutional weak voice and/or those who are prone to vocal fold pathology, vocal amplifiers may be an effective and low-cost intervention to decrease potentially damaging vocal loads and may represent a necessary form of prevention.

    This pilot study assessed the feasibility, acceptability, and utility of a text messaging system that allowed teenagers with asthma to generate and control medical reminders sent to their mobile phones. The 12 teens in the study group were able to create their own reminder text messages, add or change reminders, and determine when and how often the messages were sent to their cell phone. In total, 18 of the 21 unique messages created were reminders to take medication. No teen made changes to their original text messages or delivery schedule on their own. They gave high ratings on the usefulness, acceptability, and ease of use of the text messaging system. Self-reported asthma control at baseline was similar for both the study and comparison groups and did not change significantly. Allowing teens to control the timing and content of reminder text messages may support self-management of chronic disease.

    2009-01-01

    The objective of this study was to evaluate a Swedish version of the voice handicap index questionnaire (Sw-VHI). A total of 57 adult, dysphonic patients and 15 healthy controls completed the Sw-VHI and rated the degree of vocal fatigue and hoarseness on visual analogue scales. A perceptual voice evaluation was also performed. Test-retest reliability was analyzed in 38 subjects without voice complaints. Sw-VHI distinguished between dysphonic subjects and controls (P 0.84) and test-retest reliability (intraclass correlation coefficient >0.75) were good. Only moderate or weak correlations were found between Sw-VHI and the subjective and perceptual voice ratings. The data indicate that a difference above 13 points for the total Sw-VHI score and above 6 points for the Sw-VHI subscales is significant for an individual when comparing two different occasions. In conclusion, the Sw-VHI appears to be a robust instrument for assessment of the psycho-social impact of a voice disorder. However, Sw-VHI seems to, at least partly, capture different aspects of voice function to the subjective voice ratings and the perceptual voice evaluation.

  20. Voices in History

    Directory of Open Access Journals (Sweden)

    Ivan Leudar

    2001-06-01

    Full Text Available Experiences of “hearing voices” nowadays usually count as verbal hallucinations and they indicate serious mental illness. Some are first rank symptoms of schizophrenia, and the mass media, at least in Britain, tend to present them as antecedents of impulsive violence. They are, however, also found in other psychiatric conditions and epidemiological surveys reveal that even individuals with no need of psychiatric help can hear voices, sometimes following bereavement or abuse, but sometimes for no discernible reason. So do these experiences necessarily mean insanity and violence, and must they be thought of as pathogenic hallucinations; or are there other ways to understand them and live with them, and with what consequences?One way to make our thinking more flexible is to turn to history. We find that hearing voices was always an enigmatic experience, and the people who had it were rare. The gallery of voice hearers is, though, distinguished and it includes Galilei, Bunyan and St Teresa. Socrates heard a daemon who guided his actions, but in his time this did not signify madness, nor was it described as a hallucination. Yet in 19th century French psychological medicine the daemon became a hallucination and Socrates was retrospectively diagnosed as mentally ill. This paper examines the controversies which surrounded the experience at different points in history as well as the practice of retrospective psychiatry. The conclusion reached on the basis of the historical materials is that the experience and the ontological status it is ascribed are not trans-cultural or trans-historic but situated both in history and in the contemporary conflicts.

  3. Effects on vocal range and voice quality of singing voice training: the classically trained female voice.

    Pabon, Peter; Stallinga, Rob; Södersten, Maria; Ternström, Sten

    2014-01-01

    A longitudinal study was performed on the acoustical effects of singing voice training under a given study program, using the voice range profile (VRP). Pretraining and posttraining recordings were made of students who participated in a 3-year bachelor singing study program. A questionnaire that included questions on optimal range, register use, classification, vocal health and hygiene, mixing technique, and training goals was used to rate and categorize self-assessed voice changes. Based on the responses, a subgroup of 10 classically trained female voices was selected, which was homogeneous enough for effects of training to be identified. The VRP perimeter contour was analyzed for effects of voice training. Also, a mapping within the VRP of voice quality, as expressed by the crest factor, was used to indicate the register boundaries and to monitor the acoustical consequences of the newly learned vocal technique of "mixed voice." VRPs were averaged across subjects. Findings were compared with the self-assessed vocal changes. Pre/post comparison of the average VRPs showed, in the midrange, (1) a decrease in the VRP area that was associated with the loud chest voice, (2) a reduction of the crest factor values, and (3) a reduction of maximum sound pressure level values. The students' self-evaluations of the voice changes appeared in some cases to contradict the VRP findings. VRPs of individual voices were seen to change over the course of a singing education. These changes were manifest also in the average group. High-resolution computerized recording, complemented with an acoustic register marker, allows a meaningful assessment of some effects of training, on an individual basis and for groups that comprise singers of a specific genre. It is argued that this kind of investigation is possible only within a focused training program, given by a faculty who has agreed on the goals. Copyright © 2014 The Voice Foundation.

    2016-07-01

    Photovoice is an important participatory research tool for advancing health equity. Our purpose is to critically review how participant voice is promoted through the photovoice process of taking and discussing photos and adding text/captions. PubMed, Scopus, PsycINFO, and Web of Science databases were searched from the years 2008 to 2014 using the keywords photovoice, photonovella, photovoice and social justice, and photovoice and participatory action research. Research articles were reviewed for how participant voice was (a) analyzed, (b) exhibited in community forums, and (c) disseminated through published manuscripts. Of 21 studies, 13 described participant voice in the data analysis, 14 described participants' control over exhibiting photo-texts, seven manuscripts included a comprehensive set of photo-texts, and none described participant input on choice of manuscript photo-texts. Photovoice designs vary in the advancement of participant voice, with the least advancement occurring in manuscript publication. Future photovoice researchers should expand approaches to advancing participant voice.

    2008-01-01

    Variations in voice quality are essentially related to modifications of the glottal source parameters, such as: F0, jitter, and shimmer. Voice quality is affected by prosody, emotional state, and vocal pathologies. Psychogenic vocal pathology is particularly interesting. In the present case study, the speaker naturally presented a ventricular band voice whereas in a controlled production he was able to use a more normal phonation process. A small corpus was recorded which included sustained vowels and short sentences in both registers. A normal speaker was also recorded in similar tasks. Annotation and extraction of parameters were made using Praat's voice report function. Application of the Hoarseness Diagram to sustained productions situates this case in the pseudo-glottic phonation region. Analysis of several different parameters related to F0, jitter, shimmer, and harmonicity revealed that the speaker with psychogenic voice was capable of controlling certain parameters (e.g. F0 maximum) but was unable to correct others such as shimmer.

    2013-01-01

    Since its inception in 2007, ZeroMQ has defined a new product category of thin, fast, open source message transports. This little library has now grown into a large, vibrant community of projects tied together with standard protocols and APIs. Applications, written in any language, talk to each other over TCP, multicast, or inproc transports, using a single socket-based API, and a set of "patterns" (pub-sub, request-reply, dealer-router, pipeline). ZeroMQ handles message framing, batching, and I/O, but ignores aspects like serialization and persistence. By focussing on the essentials, and acting as a toolkit rather than a pre-packaged solution, ZeroMQ turns the complex problem of distributed computing into a relatively simple recipe. About the speaker Pieter Hintjens is a writer, programmer, and public speaker who has spent decades building large software systems, organizations, and businesses.

  12. Future-based Static Analysis of Message Passing Programs

    Directory of Open Access Journals (Sweden)

    Wytse Oortwijn

    2016-06-01

    Full Text Available Message passing is widely used in industry to develop programs consisting of several distributed communicating components. Developing functionally correct message passing software is very challenging due to the concurrent nature of message exchanges. Nonetheless, many safety-critical applications rely on the message passing paradigm, including air traffic control systems and emergency services, which makes proving their correctness crucial. We focus on the modular verification of MPI programs by statically verifying concrete Java code. We use separation logic to reason about local correctness and define abstractions of the communication protocol in the process algebra used by mCRL2. We call these abstractions futures as they predict how components will interact during program execution. We establish a provable link between futures and program code and analyse the abstract futures via model checking to prove global correctness. Finally, we verify a leader election protocol to demonstrate our approach.

    2015-01-01

    A broadcast encryption scheme with personalized messages (BEPM) is a scheme in which a broadcaster transmits not only encrypted broadcast messages to a subset of recipients but also encrypted personalized messages to each user individually. Several broadcast encryption (BE) schemes allow a broadcaster encrypts a message for a subset S of recipients with public keys and any user in S can decrypt the message with his/her private key. However, these BE schemes can not provide an efficient way to transmit encrypted personalized messages to each user individually. In this paper, we propose a broadcast encryption scheme with a transmission of personalized messages. Besides, the scheme is based on multilinear maps ensure constant ciphertext size and private key size of each user and the scheme can achieve statically security. More realistically, the scheme can be applied to the Conditional Access System (CAS) of pay television (pay-TV) efficiently and safely. PMID:26629817

More realistically, the scheme can be applied to the Conditional Access System (CAS) of pay television (pay-TV) efficiently and safely.

    In this paper, we present the first snap-stabilizing message forwarding protocol that uses a number of buffers per node being inde- pendent of any global parameter, that is 4 buffers per link. The protocol works on a linear chain of nodes, that is possibly an overlay on a large- scale and dynamic system, e.g., Peer-to-Peer systems, Grids. . . Provided that the topology remains a linear chain and that nodes join and leave "neatly", the protocol tolerates topology changes. We expect that this protocol will be the base to get similar results on more general topologies.

    In the past decade, social media like Twitter have become popular and a part of everyday life for many people. Opinion mining of the thoughts and opinions they share can be of interest to, e.g., companies and organizations. The sentiment of a text can be drastically altered when figurative language such as sarcasm is used. This thesis presents a system for automatic sarcasm detection in Twitter messages. To get a better understanding of the field, state-of-the-art systems fo...

    Full Text Available We present PolySing#, a calculus that models process interaction based on copyless message passing, in the style of Singularity OS. We equip the calculus with a type system that accommodates polymorphic endpoint types, which are a variant of polymorphic session types, and we show that well-typed processes are free from faults, leaks, and communication errors. The type system is essentially linear, although linearity alone may leave room for scenarios where well-typed processes leak memory. We identify a condition on endpoint types that prevents these leaks from occurring.

    Local multipoint distribution system (LMDS) uses cellular-like network architecture of microwave radios placed at the client's location and at the company's base station to deliver fixed services, mainly telephony, video and Internet access. The use of time-division multiple access (TDMA) and FDMA (frequency DMA) technology allows multiple customers within a 3-5 mile coverage radius to share the same radio channel. Customers can receive data rates between 64kbps to 155Mbps. LMDS was conceived as a broadband, fixed wireless, point-to-multipoint technology for utilization in the last mile. Throughput capacity and reliable distance of the link depends on common radio link constraints and the modulation method used - either phase-shift keying or amplitude modulation. In general deployment links of up to 5 miles (8 km) from the base station are possible, but distance is typically limited to about 1.5 miles due to rain fading attenuation constraints. Point-to-point systems are also capable of using the LMDS frequen...
