ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / Although the wireless data transmission technologies have evolved significantly, data recording devices are still being used because of the limitations of data rates and reliability issues over wireless environment in the avionics, military, space etc. Payload has limitation of weight. In addition, storage has limitation of capacity. So, we need to research about a data recording structure within a limited amount of memory. In this paper, we propose a new data recording structure through a condition necessary for efficient use of memory. The proposed structure has an equivalent function as other recording systems. But, it uses less memory than the other equivalent recording structures.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Many telemetry stations would like to convert from using digital-to analog converters (DAC's) to using direct digital inputs to their chart recorders but can't find a suitable recorder interface. These stations often have hundreds or even thousands of channels of information being bussed around at very high speeds on propriatary real-time computer systems. The lack of standardization has naturally presented recorder manufacturers with problems in selecting the appropriate interface hardware. Standard parallel interfaces, such as SCSI and GPIB, are usually too slow and not really suited for real-time transfer, although they can be used in some circumstances which will be described. The best choice seems to be a general purpose parallel port of at least 16 data bits which can support a large number of addresses. Such an interface can be used with a high speed network like SCRAMNet as well as with a general purpose computer or workstation. This paper will describe several available parallel ports using both TTL and RS-485 (long-line) hardware and some practical implementations of thermal array recorder use with SCRAMNet, GPIB, and general purpose parallel busses.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / VME bus has been widely accepted as an industry standard for control and process computers. The MSTI (Miniature Sensor Technology Integration) series of satellites employ a VME bus based data acquisition and control system. This system requires a ruggedized, high-speed, compact, low power and light weight data recorder for storing digital imagery from payload video cameras, as well as health and status data of the satellite. No commercial off the shelf systems were found which meet MSTI specifications. Also, a solid state device eliminates certain reliability and spacecraft pointing control problems which are encountered when using rotating (disk or tape) storage systems. The SSDR was designed to meet these requirements and it also has built-in flexibility for many general purpose applications. The electronic hardware design, which conforms to the VME bus specifications [1], can also be configured as stand-alone system. Modular memory array design allows expandability of capacity up to 320 MBytes. This paper will describe the design features of the SSDR. Performance capabilities and system implementation will be discussed. Special approaches required for application of the SSDR in space or harsh environments are also discussed.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / Chart recorders currently in use on telemetry ranges are connected to telemetry processors via a series of Digital to Analog Converters (DAC) systems. A new modular interface system receives data directly from the processor broadcast bus and distributes them to up to ten digital chart recorders. This interface is programmed from a computer to assign individual tags to each one of the display channels. This system eliminates DAC's and patch panels. It simplifies display system operation, speeds up transition from test to test and reduces maintenance costs.

This thesis reports on the findings of an international study into the way in which children approach calculations which involve the order of operations. The study involved 203 pupils aged between 12 to 14 years from four different countries: England, The USA (New York State), Japan and The Netherlands. Many pupils in England are taught to use mnemonics such as BODMAS or BIDMAS to remember the correct order of operations, and in the USA pupils are often taught to use PEMDAS. However in Japan and The Netherlands these methods are not used, and the approach to teaching mathematics differs considerably across the countries. In this study pupils from classes in these four countries have been given calculations to perform and their work has been analysed for misconceptions. The analysis of their work has involved use of the Key Recorder software as a data collection tool, in which the pupils’ calculator keystrokes have been recorded and played back to give a unique insight into their thinking. Analysis of the children’s work has resulted in the categorisation of the misconceptions that were observed, and suggests that the nature of the mathematics curriculum and the teaching methods employed may have a significant effect on the way in which children approach calculations of this sort.

abstract: ABSTRACT This project features five new pieces for clarinet commissioned from three different composers including: 1. Rasa by Jeffrey Ouper 2. Faerie Tale Dances by Jeffrey Ouper 3. Amalgamated Widget by Tavia Sullens 4. Faerie Suite by Theresa Martin 5. Time Lapse by Theresa Martin Faerie Suite and Amalgamated Widget are for unaccompanied clarinet; Time Lapse is a trio for clarinet, bass clarinet, and piano; Faerie Tale Dances is a trio for E-flat clarinet, sopranino recorder, and toy piano; and Rasa is a quartet for E-flat clarinet, two A clarinets, and bass clarinet. These pieces challenge the performer in various ways, including complex rhythm, use of extended techniques such as glissando, flutter tongue, and circular breathing, and synthetic and non-traditional scales. The composers were given guidelines prior to the compositional process to create works with a thematic connection to mythology, folklore, or fairy tales, and inspired by dance and non-western or traditional harmonies and idioms. This document offers background information about the composers and the works, and a performance guide is included for each. This guide provides recommendations and suggestions for each piece. Also included are interviews with each of the composers. Accompanying this document are recordings of each of the five pieces, performed by the author. / Dissertation/Thesis / Rasa Audio / Amalgamated Widget Audio / Faerie Tale Dances- I.

Sound propagation in very shallow water is one of the issues of the ocean acoustic. Because of close distance to the shore and short range to the bottom, the building of sound propagation model in shallow water is much more difficult than in deep water. Even though, the increasing needs of upper-sea construction engineering and near-shore surveillance make this subject more and more important. This study is to build a high sensitive underwater recording system, use it to collect data and to find out which parameters affect the sound propagation in very shallow water most. The study contains underwater recording system construction, shallow water recording experiment and comparison of OASES simulation results and the collective data. The system is constructed with two ITC6050C hydrophones and data acquisition devices. After several tests of reliability, the system is put in the sea area about 10 m depth. And the two hydrophones were moored 1 m above the bottom and 2.5 m below sea surface separately. The experiment use a moving fishing boat motor noise as sound source and the experimental results are shown as the spectrogram of sound field. The computer simulation uses OASES modules to simulate the experimental area and Pekeris waveguide propagation as the theoretical environment of very shallow water. By comparing the simulation results and the collective data ,the study finds out that the major parameters of sound propagation in the experimental area are the pressure sound speed and the depth of the sound source.

Ecological momentary assessment provides a unique way of studying quality of life factors of colorectal cancer patients. It has yet to be used to study the behavioral expression of distress or depression by colorectal cancer patients. The current study utilized the Electronically Activated Recorder (EAR) technology to capture the daily activities and conversations of forty-eight adults with colorectal cancer. The study had two purposes: 1) to test the feasibility of the EAR with colorectal cancer patients; 2) to examine separate (self-report and behavioral) indicators of physical functioning, coping, and social support for their relationship to depression. Study participants wore the EAR, a portable digital recorder, for two consecutive days as the EAR recorded 30 seconds every 12.5 minutes. The EAR digital data were transcribed and analyzed for behavioral and linguistic indicators of physical functioning, coping, and social support. The acoustic data were analyzed using the standardized coding system Social Environment Coding of Sound Inventory (SECSI) and the Linguistic Inquiry and Word Count (LIWC2007) computer program. The results provided preliminary evidence that the EAR operated as a feasible and non-disruptive tool for gathering naturalistic data about colorectal patients’ lives. The EAR data revealed information about both the colorectal patients’ internal emotional world as well as their external world which was characterized by solitary acts of daily living. Study subjects were more likely to accept and receive tangible support from others than directly discuss their cancer with others. Analysis of language found that personal disclosure to others was associated with coping through emotional support while causation words (e.g., because, effect, hence) were significantly related with self-report cognitive scales. Furthermore, the study found that first-person singular pronouns were associated not only with depression, but with appraisal of social support. Lastly, a predictive model was tested to see whether self-reported tangible and emotional support and behavioral coding of emotional support each contributed uniquely to the prediction of depression. Only self-reported tangible support was found to significantly predict depression. / text

The purpose of this study was to develop, implement and test a tool designed to help transient students gain the basic musical knowledge and skills needed to successfully complete a fourth-grade unit of recorder study. The project resulted in the development of a hypermedia-based application. The seven-week study consisted of 49 fourth-grade students. Students were given pitch reading and rhythm pattern identification pre-tests and post-tests. Students participated in weekly tests and tutorial sessions via the hypermedia-based application. At the conclusion of the study, the students were given post-tests and a performance test. The pre-test and post-test scores for the transient and established populations were analyzed. A t-test analysis revealed a significant improvement in the scores of the established and transient populations. It appears that the hyper-media application may be an effective tutorial for transient students.

The frequency disturbance recorder (FDR) is a cost effective data acquisition device used to measure power system frequency at the distribution level. FDRs are time synchronized via the global positioning system (GPS) timing and data recorded by FDRs are time stamped to allow for comparative analysis between FDRs. The data is transmitted over the internet to a central server where the data is collected and stored for post mortem analysis. Currently, most of the analysis is done with power system frequency. The purpose of this study is to take a first in depth look at the angle data collected by FDRs. Different data conditioning techniques are proposed and tested before one is chosen. The chosen technique is then used to extract useable angle data for angle analysis on eight generation trip events. The angle differences are then used to create surface plot angle difference movies for further analysis. A new event detection algorithm, the k-means algorithm, is also presented in this paper. The algorithm is proposed as a simple and fast alternative to the current detection method. Next, this thesis examines several GPS modules and recommends one for a replacement of the current GPS chip, which is no longer in production. Finally, the manufacturing process for creating an FDR is documented. This thesis may have raised more questions than it answers and it is hoped that this work will lay the foundation for further analysis of angles from FDR data. / Master of Science
