	abstract = {In the Data Air Waves Project at the University of Maryland, we are integrating Direct Broadcast Satellite (DBS) systems with terrestrial networks to provide a hybrid and effective communication substrate lying between data resources and remote/mobile user applications. Smooth integration of these two media balances the need for rapid data dissemination to very large numbers of clients and on-demand interactive data services. This paper describes the air-cache, a method for effective data broadcasting and an algorithm which rapidly adapts the content of the cache based on the "misses" which result in explicit (on-demand) data requests. Simulation results show that the hypothesis of adapting based only on the misses performs quite reasonable and has very little deviation from a system that has complete information - both hits and misses.},

In the resultant system, the user, supported by an enhanced tradeoff analysis capability, can select and describe a promising preliminary design and process plan based on the analysis of a variety of alternatives from both an electrical and mechanical perspective. This preliminary design is then subjected to further analysis and refinement using existing EDAPS capabilities. In addition to the integration of these two systems, specific new functions have been developed, including tradeoff analysis over a much broader set of criteria, and the ability of the tradeoff module to query the process planner to determine costs of individual options.},

	abstract = {This paper considers the problem of constructing reduced complexity controllers for output feedback nonlinear H$\infty$ control. Conditions are obtained under which such controllers achieve the closed loop performance requirements. These controllers are non-optimal in general. However, in case optimality holds, they are in fact the certainty equivalence controllers. Conditions under which certainty equivalence holds are simplified and linked to the solvability of a functional equation.},

We pose the problem in a risk-sensitive control framework, and derive the recursion for the information state. We then take large deviation type limits, and go on to show that the limiting information state recursion is related to that arising in solving ultimate boundedness control problems. For completeness we present the solution to the deterministic problem. The paper ends with an example involving application of run to run control to end-pointing.},

	year = {1996},
	month = {05/1996},
	abstract = {The performance degradation as a result of acoustical environment mismatch remains an important practical problem in speech recognition. The problem carries a greater significance in applications over telecommunication channels, especially with the wider use of personal communications systems such as cellular phones which invariably present challenging acoustical conditions. In this work, we introduce a vector quantization (VQ) based compensation technique which both makes use of a priori information about likely acoustical environments and adapts to the test environment to improve recognition. The technique is progressive and requires neither simultaneously recorded speech from the training and the testing environments nor EM-type batch iterations. Instead of using simultaneously recorded data, the integrity of the updated VQ codebooks with respect to acoustical classes is maintained by endowing the codebooks with a topology of reference environment. We report results on the McCaw Cellular Corpus where the technique decreases the word error for continuous ten digit recognition of cellular hands-free microphone speech with land line trained models from 23.8\% to 13.6\% and the speaker dependent voice calling sentence error from 16.5\% to 10.6\%.},

	abstract = {We study the problem of choosing an image based optimal wavelet basis with compact support for image data compression and provide a general algorithm for computing the optimal wavelet basis. We parameterize the mother wavelet and scaling function of wavelet systems through a set of real coefficients of the relevant quadrature mirror filter (QMF) banks. We further introduce decomposition entropy as an information measure to describe the distance between a given digital image and its projection into the subspace spanned by the wavelet basis. The optimal basis for the given image is obtained through minimizing this information measure. The resulting subspace is used for image analysis and synthesis. Experiments show improved compression ratios due to the application of the optimal wavelet basis and demonstrate the potential applications of our methodology in image compression. This method is also useful for constructing efficient wavelet-based image coding systems.},

We limit the interface to the kernel to be read/write, and introduce two cells, atleast~one of which needs to be a system service (dsplice system call or implemented otherwise). These calls use file descriptor as input and output parameters, and because of that have a much more flexible interface than the traditional ioctl/fcntl~interface. The resulting API can be used to construct efficient communication schemes and result in simpler and efficient ways for distributed interaction. Parts of this API have been implemented in our ongoing experiments. The adjoining figures outline the potential for flexibility.},
