International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / In face of the characteristics of multiple data streams, high bit rate, variable data formats, complicated frame structure and changeable application environment, the programmable PCM telemetry system needs a new data processing system with advanced telemetry system architecture. This paper fully considers the characteristics of real-time telemetry data processing, analyzes the design of open system architecture for real-time telemetry data processing system(TDPS), presents an open system architecture scheme and design of real-time TDPS, gives the structure model of distributed network system, and develops the interface between network database and telemetry database, as well as telemetry processing software with man-machine interface. Finally, a practical and multi-functional real-time TDPS with open system architecture has been built, which based on UNIX operating system, supporting TCP/IP protocol and using Oracle relational database management system. This scheme and design have already proved to be efficient for real-time processing, high speed, mass storage and multi-user operation.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / Discover how it is now possible to memory-link all man-in-the-loop and machine-in-the-loop elements, as global resources that share information at memory-access speeds, to provide a unified system paradigm that avows: "the data is there, on time, every time." Regardless of configuration, if your past, present, or future system consists of more than one computer, and it interactively mixes information sources and destinations (e.g. Telemetry data streams, I/O interfaces, information processors, etc.) to achieve a highly integrated system, then the critical path to real-time success mandates a high performance, reliable, and deterministic communications methodology. This softwareless, future technology is already successfully sharing information in other real-time markets and applications, and is ready for more challenging applications.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / An artificial neural network (ANN) for use in real time data reduction and analysis will be presented. The use and advantage of hardware and software implementations of neural networks will be considered. The ability of neural networks to learn and store associations between different sets of data can be used to create custom algorithms for some of the data analysis done during missions. Once trained, the ANN can distill the signals from several sensors into a single output, such as safe/unsafe. Used on a neural chip, the trained ANN can eliminate the need for A/D conversions and multiplexing for processing of combined parameters and the massively parallel nature of the network allows the processing time to remain independent of the number of parameters. As a software routine, the advantages of using an ANN over conventional algorithms include the ease of use for engineers, and the ability to handle nonlinear, noisy and imperfect data. This paper will apply the ANN to performance data from a T-38 aircraft.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / This paper presents the method of real time telemetry data synthesis for multi-beams and multi-receivers system in theory. For the practical implementation, we introduce a TMS320C25-based data synthesis board. Through a large number of simulating experiments, the satisfactory results are obtained, which obviously improve the performance of telemetry system. Therefore, all those technigues and results have the value of practical applications.

Approved for public release, distribution unlimited / In this thesis I examine the theory of Valued Information at the Right Time (VIRT) and the benefits its implementation can provide to the Navy's best example of accurate information-sharing, the Cooperative Engagement Capability (CEC). The primary premise of VIRT is that only information which has some value to the user and could impact mission accomplishment should be allowed to flow from a source to the user. If information has little or no value to the individual it is destined for, it must simply be regarded as overhead and should not be sent/received. Using a simple simulation I show in this thesis that VIRT has the potential to provide benefits of orders of magnitude versus a non-VIRT implementation. The Navy's CEC program represents a premier air track data sharing mechanism. It enables ships augmented with this capability and residing on the network to share fire control quality information on the individual parameters of air tracks such as location, course, speed, and altitude. There is a place for VIRT implementation within CEC. Such an implementation can prove beneficial both to CEC as an internal user of information and also as a supplier to external entities of its valuable track information. Finally, I provide a notional VIRT-enabled, product-line architecture for a coalition information-sharing system. If both the concept of VIRT and CEC are to have a place in the future of information-sharing, the issue of providing this information to our coalition partners must be addressed.

A dissertation submitted to the Faculty of Engineering, University of the Witwatersrand, in fulfilment of the requirements of the degree of Master of Science Engineering / A framework designed to contain and manage the use of knowledge in a real-time knowledge based system for high level control of an industrial process is presented. A prototype of the framework is designed and implemented on a static objectorientated shell. Knowledge is stored in objects and in forward chaining rules. The knowledge has a well defined structure, making it easy to create and manage. Rules are used to recognize conditions and propose control objectives. The framework uses the knowledge to determine variables that if altered will meet the objectives. Control actions are then found to implement changes to these variables The use of explicit control objectives makes it possible to determine if an action worked as intended and if its use is suitable for the present conditions. This enables a learning mechanism to be applied in the expert system. The prototype operated adequately, but the knowledge required to drive the. system was found to be very detailed and awkward to create. / Andrew Chakane 2018

Electronic equalization has recently attracted considerable interest for impairment compensation for its significant cost saving and adaptive compensation capability. In this thesis, we propose novel maximum-likelihood sequence estimation (MLSE) structures for various advanced modulation formats. Electronic equalization of advanced modulation formats further extends the transmission reach and relaxes the speed limitation of electronic devices. We also propose novel application of MLSE for mitigation of timing misalignment between the pulse carver and data modulator in return-to-zero (RZ) systems. / In access networks, we focus on the achievement of centralized light source (CLS) wavelength-division-multiplexing passive optical networks (WDM-PON) with data rate of 10 Gbit/s for both downstream and upstream signals. The previous CLS WDM-PON schemes at 10 Gbit/s suffer from chromatic dispersion (CD) and/or asynchronous upstream modulation. We propose two solutions to mitigate these impairments. By eliminating the modulation synchronization module and all-optical CD compensation module, the proposed methods greatly reduce the cost and operation complexity of high-speed WDM-PON. / In the monitoring for impairment compensation, we propose a polarization-insensitive monitoring scheme for synchronized phase re-modulation by using a narrowband optical-passband filter (OBPF). With the optimal central wavelength of the OBPF, high monitoring sensitivity is achieved. / The increasing bandwidth demands have aroused a myriad of industry and academic activities to develop cost-effective optical communication systems with data rates of 10 Gbit/s and beyond. However, as the capacity grows, many signal degradation effects become prominent and seriously limit the data rate and the transmission distance. The mitigation of the impairments inevitably increases the operation complexity and implementation cost. The focus of this thesis is to develop new impairment mitigation approaches to improve the impairment compensation performance and/or to reduce the operation complexity and cost. As a result, cost-effective high-speed optical communication systems are enabled. / To freely enable the employment of advanced modulation formats for optical communications, we propose all-optical conversion from 40-Gbit/s RZ signal to 40-Gbit/s inverse-RZ/10-Gbit/s differential-phase-shift-keying orthogonal modulation signal to interface high-speed transmission systems using RZ format with networks using orthogonal modulation format. We also propose a novel all-optical coding and decoding scheme for 20-Gbit/s four-amplitude-shift-keying signal. / Zhao Jian. / "July 2007." / Adviser: Lian-kuan Chen. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0579. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 152-173). / Electronic reproduction.
