Adaptive Critic Based Neurocontroller For Autolanding Of Aircrafts, S. N. Balakrishnan, Gaurav Saini

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper, adaptive critic based neural networks have been used to design a controller for a benchmark problem in aircraft autolanding. The adaptive critic control methodology comprises successive adaptations of two neural networks, namely action and critic network (which approximate the Hamiltonian equations associated with optimal control theory) until closed loop optimal control is achieved. The autolanding problem deals with longitudinal dynamics of an aircraft which is to be landed in a specified touchdown region (within acceptable ranges of speed, pitch angle and sink rate) in the presence of wind disturbances and gusts using elevator deflection as the control …

Ontologies For Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

An ontology is a computational model of some portion of the world. It is often captured in some form of a semantic network-a graph whose nodes are concepts or individual objects and whose arcs represent relationships or associations among the concepts. This network is augmented by properties and attributes, constraints, functions, and rules that govern the behavior of the concepts. Formally, an ontology is an agreement about a shared conceptualization, which includes frameworks for modeling domain knowledge and agreements about the representation of particular domain theories. Definitions associate the names of entities in a universe of discourse (for example, classes, …

Mobile Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

A lot of agents are executing on the Web, and some of them are starting to move around. While most agents are static (existing as a single process or thread on one host), others can pick up and move their code and data to a new host where they resume executing.

Internet-Based Agents: Applications And Infrastructure, Munindar P. Singh, Michael N. Huhns

Faculty Publications

Software agents are mitigating the complexity of modern information systems—technically by providing a locus for managing information subsets, and psychologically by providing an abstraction for human interaction with them.

Hierarchical Classification As An Aid To Browsing, John R. Rose, Caroline M. Eastman

Faculty Publications

An approach to browsing large chemical reaction databases is presented. The method that is described builds on earlier work in which unsupervised hierarchical classification was used to extract generalizations of reaction classes from reaction databases for use in reaction knowledge bases. The method described in this paper involves classification based on both semantic and topological features. It supports the creation of deep hierarchies in which succeeding levels represent increasing degrees of abstraction. The creation of a hierarchy allows the user to quickly locate interesting items or classes of items by performing a tree traversal as opposed to sequentially scanning a …

An Analog Integrated Circuit For Continuous-Time Gain And Offset Calibration Of Sensor Arrays, Yu Ming Chiang, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

Parameter variations cause unavoidable nonuniformities in Infra-Red Focal Plane Arrays and other integrated sensors. Since these nonuniformities change slowly with time, calibrating sensors one-time only is not suitable-much more frequent calibration is required. We have developed an algorithm that continually calibrates an array of sensors that contain gain and offset variations. This algorithm has been mapped to analog hardware and designed and fabricated with a 2um CMOS technology. Measured results from the chip show that the system achieves invariance to gain and offset variations of the input signal.

Microlanguages For Operating System Specialization, Calton Pu, Andrew P. Black, Crispin Cowan, Jonathan Walpole, Charles Consel

Computer Science Faculty Publications and Presentations

Specialization is a technique that has the potential to provide operating system clients with the performance and functionality that they need, while still retaining the advantages of a simple generic code base for the operating system maintainer. However, at present the specialization process is labor-intensive and requires the knowledge of an expert in the domain of application behavior. In order to realize the full advantages of specialization, we believe that the process must be automated. This means building tools for specialization, and also making the domain knowledge explicit in some form or other. A specialization toolkit has been developed jointly …

Physical Media Independence: System Support For Dynamically Available Network Interfaces, Jon Inouye, Jim Binkley, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Advances in hardware technology has fueled the proliferation of dynamically configurable network interface cards. This empowers mobile laptop users to select the most appropriate interface for their current environment. Unfortunately, the majority of system software remains "customized" for a particular network configuration, and assumes many network characteristics remain invariant over the runtime of the software. Physical Media Independence (PMI) is the concept of making assumptions about a particular device explicit, detecting events which invalidate these assumptions, and recovering once events are detected. This paper presents a model supporting PMI. Based on device availablilty, the model identifies implicit device-related assumptions made …

Neutron Transmutation Doping As An Experimental Probe For Cuzn In Znse, Edward D. Wheeler, Jack L. Boone, J. W. Farmer, H. R. Chandrasekhar

Electrical and Computer Engineering Faculty Research & Creative Works

Nuclear transmutation is employed in an investigation of copper doping in ZnSe. Copper atoms are introduced at zinc sites in ZnSe after crystal growth processes are complete. Since the copper dopants are introduced after growth, far from equilibrium, they are less able to form complexes with other dopants or lattice defects as they may do when present during crystal growth. Initial results are consistent with CuZn being involved in the copper red and copper green emissions in ZnSe but not in the if exitonic emission. © 1997 American Institute of Physics.

The Economic And Social Impacts Of Nimbys, Terance J. Rephann

Regional Research Institute Working Papers

This paper examines some of the issues and controversies that arise when facilities with perceived noxious environmental, social, and economic effects (NIMBYs) locate in communites. Five specific categories of NIMBYs are examined, including: (1) interstate highways, (2) large dams, (3) medium and maximum security prisons, (4) commercial nuclear power plants, and (5) gambling casinos. The paper uses quasi-experimental control group methods to assess the economic impacts of these facilities on U.S. counties during the period 1972-94. The paper shows that few actual negative effects can be attributed to NIMBYs. However, only interstate highways result in broad based effects that measurably …

Distribution-Free Statistical Inferences For Testing Marginal Changes In Inequality Indices, Buhong Zheng, Brian Cushing

Regional Research Institute Working Papers

This paper develops asymptotically distribution-free inference for testing inequality indices with dependent samples. It considers the interpolated Gini coefficient and the generalized entropy class, which includes several commonly used inequality indices. We first establish inference tests for changes in inequality indices with completely dependent samples (i.e., matched pairs) and then generalize the inference procedures to cases with partially dependent samples. The effects of sample dependency on standard errors of inequality changes are examined through simulation studies as well as through applications to the CPS and PSID data.

The Hydrography And Circulation Of The Upper 1200 Meters In The Tropical North Atlantic During 1982-91, Gennady Chepurin, James A. Carton

Journal of Marine Research

We assemble a collection of 7591 conductivity-temperature-depth stations in the tropical Atlantic between 5S and 20N for the period 1982–1991 using data from the Soviet SECTIONS program enhanced by contributions primarily from the WESTRAX and FOCAL/SEQUAL programs. Most of the stations are west of 30W, forming a series of 21 surveys. In addition there were five multi-ship basinwide surveys, each taking 1.5–3 months to complete. The quality of the SECTIONS data is discussed and comparisons between the data sets are shown. Within the pycnocline, southern water is distinguished by salinity that is 0.3 psu lower than its northern counterpart at …
