The abstract provided by the Pentagon follows: Human body tracking for synthetic environment interface has become a significant human- computer interface challenge. There are several different types of motion capture systems currently available. Inherent problems, most resulting from the use of artificially-generated source signals, plague these systems. A proposed motion capture system is being developed at the Naval Postgraduate School which utilizes a combination of inertial sensors to overcome these difficulties. However, the current design exhibits azimuth drift errors resulting from the use of inertial sensors. This thesis proposes a new method of compensating for azimuth drift using a three-axis fluxgate magnetometer. The magnetometer capable of azimuth drift compensation since its sensitive axis is not collinear with the local vertical. This thesis includes a program for simulating the operation of a fluxgate magnetometer in C++. The included C++ code simulates a fluxgate magnetometer and provides an estimate of azimuth based on the magnetometer's output which is typically within five degrees of the actual azimuth. Real magnetometer data for testing and verification was accomplished by bench testing a real fluxgate magnetometer..

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A579953. The abstract provided by the Pentagon follows: This thesis is written to document the design and use of an object- oriented, numerical simulation of thermoacoustic devices. The resulting expen system code entitled "Design Simulation for Thermoacoustic Research", or DSTAR, allows a unique new approach for the rapid design and simulation of thermoacoustic devices. Past approaches to thermoacoustic modeling have involved the use of "disposable" algorithms coded to model one specific device. Conversely, DSTAR uses a Windows compliant graphical user interface to construct any given thermoacoustic model at runtime. As a result, the models can be developed quickly and without any revision of the computer code. The approach to simulation involves the solution of a one-dimensional acoustic wave equation concurrently with an energy flow equation from one end of the user-specified device geometry to the other in addition to various lumped acoustical elements. The resulting steady-state solution is displayed in both graphical and textual output. Considerable effort was given to preserving the flexibility and breadth of the possible simulations, in addition to allowing easy modification of the source code for new thermoacoustic components. To demonstrate the utility of the code, a thermoacoustic prime mover was modeled and then optimized for better performance..

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A593793. The abstract provided by the Pentagon follows: Current two dimensional preliminary design codes use structured programming, which is rigid and does not allow the user to vary parameters easily. This study uses object-oriented programming to allow the user to vary all selectable parameters in a familiar Windows operating environment. The programmed design is based on the assumptions of axial and free-vortex flow between blade rows, simple radial equilibrium, and a thermally and calorically perfect gas. The program allows a fan or core stage design and uses an open architecture to facilitate upgrades and extensions. Using the Naval Postgraduate School's (NPS) transonic compressor design as input, the preliminary design code output was compared to the detailed throughflow design of the transonic compressor. The results agreed reasonably well with detailed throughflow design. With some minor improvements this code can easily be used to develop a preliminary design that can be optimized to the user's requirements..

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A871083. The abstract provided by the Pentagon follows: Authentication is particularly important in the SAAM system because SAAM uses mobile codes, called resident agents. These resident agents are loaded onto SAAM routers dynamically, and execute on the destination SAAM router. Mobile code in the SAAM system requires an authentication scheme to prevent an outsider from sending a malicious resident agent. The primary focus of this research is to find the best-fit authentication scheme for the SAAM system. SAAM with authentication can be used as the technical network infrastructure to support Network Centric Warfare (NCW) as described in JV2OlO. The prototype in this thesis authenticates new nodes that join a SAAM network using Kerberos. Signaling data, called control traffic, is authenticated with a dynamic signature key that changes every two minutes. Once a SAAM node is authenticated, its identity is protected throughout the battle..

The abstract provided by the Pentagon follows: The purpose of this thesis is to model a satellite communication system with VSATs, using Spread Spectrum CDMA methods and Forward Error Correction (FEC), Walsh codes and PN sequences are used to generate a CDMA system and FEC is used to further improve the performance. Convolutional and block coding methods are examined and the results are obtained for each different case, including concatenated use of the codes, The performance of the system is given in terms of Bit Error Rate (BER), As observed from the results, the performance is mainly affected by the number of users and the code rates,.

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A219193. The abstract provided by the Pentagon follows: With the decline in military spending, the United States relies heavily on state side support. Communications has never been more important. High-quality audio and video capabilities are a must. Watermarking, traditionally used for copyright protection, is used in a new and exciting way. An efficient wavelet-based watermarking technique embeds audio information into a video signal. Several highly effective compression techniques are applied to compress the resulting audio/video signal in an embedded fashion. This wavelet- based compression algorithm incorporates bit plane coding, first difference coding, and Huffman coding. To demonstrate the potential of this audio embedding audio/video compression system, an audio signal is embedded into a video signal and the combined signal is compressed. Results show that overall compression rates of 15:1 can be achieved. The video signal is reconstructed with a median PSNR of nearly 33dB. Finally, the audio signal is extracted with out error..

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A009924. The abstract provided by the Pentagon follows: Complex multilevel secure (MLS) architectures are emerging that require user identification and authentication services not only from multilevel connections, but from pre-existing single level networks. The XTS-400 can be used as a server in such environments. Trusted devices are required for user login via multilevel connections; however, single level remote login facilities do not require such client-side devices. Instead, a more lightweight mechanism is possible. Remote login capabilities do not exist on the XTS-400 for use over the single level networks and this capability is a desired feature for use in complex multilevel architectures. OpenSSH is an application, developed for OpenBSD, that uses the SSH protocol to provide secure remote logins and an interactive command interface. A secure remote login application, OpenSSH, was ported to the XTS-400 in order to provide remote login capabilities. The porting process identified differences between the original development platform for OpenSSH and the XTS- 400. Solutions, in the form of source code modifications, were made to overcome problems resulting from the compatibility differences encountered during the port. Testing was conducted to ensure that the port was successful and did not violate any security policies enforced by the XTS-400..
