	abstract = {We consider the problem of robust output feedback control of set-valued discrete time systems. Such systems appear frequently in applications such as process control. The aim is to motivate and obtain an efficient formulation of robust control problems and the resulting structure of the controller for such systems. This formulation, and the controller structure are obtained by taking small noise limits of the information state dynamics arising in a related risk-sensitive stochastic control problem. The necessary and sufficient conditions for solvability are also presented.},

Also, the small noise case is considered. The limit problem is a differential game with output control. The full justification of all the results is still a long range plan.},

We consider a multiobjective optimization model that determines components and processes for a given conceptual designs for microwave modules. This model outputs a set of solutions that are Pareto optimal with respect to cost, quality, and other metrics. In addition, we identify System integration issues for Manufacturing applications, and propose an architecture which will serve as a building block to our continuing research in virtual manufacturing applications.},

An interesting consequence of using the set valued approach is that now we can relax the assumptions made on the statistics of the noise. Hence, we can also deal with non-Gaussian and correlated noise. We provide results comparing the performance of the controller to a recursive least squares based controller.},

	abstract = {In this paper we investigate the problem of fast and accurate classification of naval targets from radar returns. The algorithms can be applied to both 1-D and 2-D data (i.e. high range resolution and imaging radar returns). We describe the structure of these algorithms and report experimental results on their performance with synthetic returns from ships.

We have successfully addressed the problem of reducing the target model representations with respect to viewpoint variations and other Sensor parametric variations. Our method can be viewed as a quantization of the space of sensing Operations. The resulting multiresolution aspect graph is a (relational) graph representation of this quantization. Aspect graphs of target radar returns are generated algorithmically. Since our off-line model/parameter tuning methods are based on general vector quantization, our methods extend naturally and efficiently to multi-sensor data: LADAR, TV, mmWave, SAR, etc.. We describe new results on the {\textquotedblleft}continuity{\textquotedblright} of the aspect graph, new properties and improvements of our algorithmic constructions.

Our basic classification algorithm utilizes a cascade of a wavelet preprocessor followed by a tree-structured clustering algorithm: a learning mode can be also added. We develop a high performance parallel progressive classification algorithm and report On its performance and Complexity. We show experiments illustrating that the parallel algorithm Outperforms a Compound version (which is the more intuitive choice) and that it has performance close to Bayes optimal classification (via comparison to Learning Vector Quantization). We Outline an analytical framework for establishing these results theoretically. We also discuss similar experiments from face recognition and medical image classification problems.},

We further introduce the concept of 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. A gradient based Optimization algorithm is developed for computing the image based optimal wavelet basis. 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.},

Because it has been developed using MATLAB, the WSPW is easily extensible and inherently portable between varying system architectures. Although the emphasis of this paper is on the wavelet representation of signals, the WSPW has proven itself a valuable tool in applications including radar source identification and signal classification.},

	abstract = {Today{\textquoteright}s telecommunications networks are becoming increasingly large, complex, mission critical and heterogeneous in several dimensions. For example, the underlying physical transmission facilities of a given network may be "mixed media" (copper, fiber-optic, radio, and satellite); the Sub networks may be acquired from different vendors due to economic, performance, or general availability reasons; the information being transmitted over the network may be "multimedia" (video, data, voice, and images) and, finally, varying performance criteria may be imposed e.g. data transfer may require high throughput while the others, whose concern is voice communications, may require low call blocking probability. For these reasons, future telecommunications networks are expected to be highly complex in their services and operations. Due to this growing complexity and the disparity among management systems for individual sub networks, efficient network management systems have become critical to the current and future success of telecommunications companies. This paper addresses a research and development effort which focuses on prototyping configuration management, since that is the central process of network management and all other network management functions must be built upon it. Our prototype incorporates ergonomically designed graphical user interfaces tailored to the network configuration management subsystem and to the proposed advanced object-oriented database structure. The resulting design concept follows open standards such as Open Systems Interconnection (OSI) and incorporates object oriented programming methodology to associate data with functions, permit customization, and provide an open architecture environment.},

	abstract = {Access to the Internet is either too slow (dial-up SLIP) or too expensive (switched 56 kbps, frame relay) for the home user or small enterprise. The Center for Satellite and Hybrid Communication Networks and Hughes Network Systems have collaborated using systems integration principles to develop a prototype of a low-cost hybrid (dial-up and satellite) network terminal which can deliver data from the Internet to the user at rates up to 160 kbps. An asymmetric TCP/IP connection is used breaking the network link into two physical channels: a terrestrial dial-up for carrying data from the terminal into the Internet and a receive-only satellite link carrying IP packets from the Internet to the user. With a goal of supporting bandwidth hungry Internet applications such as Mosaic, Gopher, and FTP, this system has been designed to support any Intel 80386/486 PC, any commercial TCP/IP package, any unmodified host on the Internet, and any of the routers, etc., within the Internet. The design exploits the following three observations: 1) satellites are able to offer high bandwidth connections to a large geographical area, 2) a receive-only VSAT is cheap to manufacture and easier to install than one which can also transmit, and 3) most computer users, especially those in a home environment, will want to consume much more information than they generate.

Two common voice/data integrated protocols such as fixed boundary and movable boundary schemes for the satellite channel are investigated, and the performance of both schemes is evaluated. The optimal splitting ratios for voice and data at the SIMPs (Satellite Interface Message Processors) are found using a powerful numerical optimization package (FSQP). We also develop dynamically optimal splitting ratios between satellite network and terrestrial network for data and voice traffic. We constantly monitor the traffic and measure the arrival rate and occupancy of every link. Based on these data, we optimize data traffic delay in a suitable time-frame under the constraints of voice traffic blocking probabilities of voice transmission links being less than specified value, which is up to system{\textquoteright}s design or users{\textquoteright} requirements.
