Telemetry Course

Engel, Jim, Menas, Jim 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / This paper presents a new multimedia CD ROM course on Telemetry that has is just being developed for DoD by the Defense Test and Evaluation Professional Institute (DTEPI). The paper will discuss the Commercial Off the Shelf (COTS) software packages that were used to develop the course. It will discuss the methodology used to develop the course and lessons learned in its development. During the presentation of this paper a computer and VGA projector will be used to show some of the material in the course. This is the second CD ROM course developed by DTEPI, the first one was on Time, Space-Position Information (TSPI). The TSPI course has been completed, passed Beta testing at most of the National Ranges, and has been released. About 800 CD ROM disks have been distributed to the Ranges and other qualified users. The Telemetry course will be similarly completed and distributed. The course is intended to be an introduction to the subject of telemetry for use by engineering professionals just entering the workforce, by professionals cross training into T&E, and by others with a need or desire to understand telemetry. The value of developing an interactive course using audio narration, animations, as well as still pictures and video of actual instrumentation and equipment cannot be overemphasized. This multimedia environment makes the explanation of concepts like an optical encoder easily understandable as the student can "see" a simulation of the encoder in operation. The course is designed to be self paced with students controlling their own progress and choosing the topics they want to cover. The student also has the option to print a hard copy of the page narration or read them on screen. The course facilitates the rapid learning of the jargon of telemetry, all the essential acronyms, the way telemetry systems work, what they look like, and many of the limitations of telemetering systems. The course covers the History of Telemetering, Telemetry Subsystems, Range Applications, Telemetry Schemes, Theory of Operation, Telemetry Processing Systems, Testing Telemetry Systems, and other Miscellaneous Topics. It will afford the student a lot of insight into telemetry without the mathematics and detail required of a telemetry design engineer.

Intersectional analysis of female prisoner's depictions in Orange is the New Black

Watson, Arianne 29 June 2016 (has links)
<p> The purpose of this research is to critically analyze Orange is the New Black (OITNB) by conducting an intersectional analysis of seasons 1 and 2. Imprisoned women are excluded from discussions about their oppression. Incarcerated women lack: 1) the four domains of power, which are hegemonic, interpersonal, disciplinary, and structural; and 2) control of their representations. Media&rsquo;s representations about imprisoned women are accessible through movies, television news, television shows, and newspapers; which have consistently depicted women in prison inaccurately as &ldquo;bad&rdquo;, violent, and sexually insatiable. The women who write prison narratives books are not representative of the female prison system, often reflecting their personal experience. </p><p> OITNB is an internationally famous and award-winning show with a readily accessible and influential platform (Netflix). OITNB is relevant to the current discussion of imprisoned women and their representation of females; thus, it is important to ask how the show presents and depicts the women&rsquo;s Federal prison system. An intersectional analysis will examine how women of different racial/ethnic groups and criminal offenses are represented in OITNB. To establish whether OITNB is disrupting or reinforcing these images for women imprisoned as a whole, or for specific racial/ethnic groups, or criminal offense types.</p>

Multimedia Codec Evaluation and Overview

Dernaika, Ghina, Khavtasi, Sophia January 2007 (has links)
Movies, songs, conferences, video streams and other multimedia services are spreading in everybody’s life, needs and work. Different types of audio and video codecs of various qualities appear to be used for different purposes. However, each codec can be suitable for a special usage, as for example a codec that can be use for high quality film may not be suitable for streaming it into network. The main purpose of this thesis is to compare the performance of different codecs in one particular scenario and indicate which codec performance is the best. The thesis work includes the investigation of several codec aspects (audio and video) and problems related to choosing a multimedia codec (coder/decoder) suitable for large-scale multimedia distribution over the Internet. More specifically, the work focuses on various features of modern media codecs, compares them and finds the best application for each of them. Furthermore, the thesis provides an overview of available research results related to this work and codec comparison tables for codecs and their features. Additionally, as part of this work, a testbed was developed to measure the performance of codecs when used to stream media over a network. The testbed enabled the collection of various QoS parameters, such as bandwidth usage and burst, size for each codec considered in this thesis. / Address: Minervavägen 22A, Room 2, 371 41 Karlskrona, sweden.

End-user interfaces to electronic books

Richards, Stephen M. January 1994 (has links)
Electronic book production is a developing field which is still in its infancy. As such, there is still relatively little material available in the form of design principles or guidelines for the production of such books. It is also extremely complex, in that electronic book designers can take advantage of a number of delivery techniques which are not available to authors of traditional paper-based books. Such techniques include: multimedia (the delivery of text, pictures, sound, and moving pictures); and hypermedia (the linking of reactive information items to form non-linear structures). This research investigates some of the key issues in the design of end-user interfaces to electronic books. Essentially, this centres on three basic problems: the use of metaphors in the design of interfaces to electronic books; models for the design of multimedia pages; and the provision of various knowledge corpus structures. Interface metaphors are investigated through the implementation and evaluation of the book metaphor. Applications were developed which either embedded or did not embed the book metaphor. Subjects used these applications while undertaking a number of information access tasks. Both qualitative and performance data werecollected and some significant results were obtained. Five page models were developed (referred to as: simple; tiled; overlay; oversize; and dynamic) which were used to design a number of page structures. These page structures were evaluated using qualitative measures of user reactions to the various page structures. Seven interface dimensions were measured and again significant results were obtained. To measure the effects of knowledge corpus structure on the design of electronic books three different book structures were created: linear; tree; and network. These were investigated in the light of some common information access tasks. The results indicated that some knowledge corpus structures were more appropriate for certain types of task.

Multimedia Technology and Indigenous Language Revitalization: Practical Educational Tools and Applications Used Within Native Communities

Galla, Candace Kaleimamoowahinekapu January 2010 (has links)
This dissertation reports findings from a study documenting the use of multimedia technology among Indigenous language communities to assist language learners, speakers, instructors, and institutions learn about multimedia technologies that have contributed to Indigenous language revitalization, education, documentation, preservation, and maintenance. The overall study used an adapted technacy framework to investigate how Indigenous language advocates holistically understand, skillfully apply and communicate creative and balanced technological solutions that are based on understanding of contextual factors (Seemann & Talbot, 1995). The research presented is based on a survey of individuals who used technology for Indigenous language revitalization purposes, as well as on case studies of students of the American Indian Language Development Institute (AILDI) who enrolled in the technology course, Computer Applications for Indigenous Language Communities. The survey provided an overview of the types of technologies Indigenous communities are using for the revitalization of their language. In the study, case studies were also conducted to provide an in-depth understanding of where, when, why, and how users are implementing these technologies in their home, communities, and schools. Research questions, participants, and data collection were organized and analyzed according to three levels: multimedia technology use among Indigenous language communities, Indigenous language institutes and technology training, and AILDI student case studies.Many Indigenous communities are facing language endangerment and extinction and are looking for ways to preserve, document, revitalize and maintain their languages. One way is the integration of technology. Findings from the study suggest that the language goals of the community need to be determined prior to the incorporation of technology in these efforts. The study also found that regardless of the size of the community, opportunities for using technology in Indigenous language revitalization efforts were shaped by literacy and oral proficiency of the community, as well as linguistic and cultural, social, economic, environmental, and technological factors as expressed in the adapted technacy model. Overall, the study underscored the importance of taking context into consideration in order to make grounded choices about technology as a component of contemporary language revitalization efforts.

Adaptive Techniques and Optimizations for Media Streaming over Wireless Channels

Hassan, Mohamed Said Abdou Ibrahim January 2005 (has links)
Enabling efficient media streaming over wireless channels requires efficient utilization of the limited wireless spectrum while satisfying multimedia applications' quality of service (QoS) requirements. In this dissertation, we provide insights into network and application-centric approaches for media streaming over wireless channels. In network-centric approaches, the fundamental problem is how to model network variations at the different layers and optimize the total quality across these layers. We use Finite-state Markov chain (FSMC) models to investigate the packet loss and delay performance over a wireless link. We propose a new method for partitioning the received SNR space that results in a FSMC model with tractable queueing performance. We then use this model to derive closed-form expressions for the {\em Effective Bandwidth\/} subject to either packet loss or packet delay constraints. In application-centric approaches, we take into account the VBR nature of video frames and channel dynamics and integrate in the analysis the dynamics of the playback buffer occupancy. We introduce a mixture of sourec/channel rate adaptation schemes that target efficient utilization of the wireless spectrum and safeguard the continuity of media streaming over wireless channels. First, we propose two source-rate control schemes for streaming video over wireless channels that provide gracefully degraded quality and soft guarantees on frame delay. The schemes are designed to maximize the source bit rate at the encoder while preventing/reducing events of starvation at the decoder. Second, we present a novel cycle-based rate adaptation scheme. The scheme is designed to maximize the source bit rate at the encoder while guaranteeing an upper bound on the probability of starvation at the playback buffer. This approach can be applied to both {\em one-way} and {\em interactive} video. Finally, we propose a playback-adaptive source/channel rate control (SCRC) for video streaming over wireless channels. We exploit the so-called playback adaptation margin and the playback buffer occupancy to control the source and channel rates. The SCRC scheme is designed to limit potential playback discontinuities that may occur due to variations in the wireless link.
