A solution is presented to the L/sup 1/ minimization problem for plants with commensurate delays. In the special case where the weight has one pole, the problem can be solved by a single linear programming problem. Other special cases are also presented. A method for computing the optimal performance and a characterization of minimizing solutions are given.< >
High-resolution x-ray scattering measurements on heavily doped Si:As (5×1021 As cm−3) show lattice compression relative to pure silicon, Δaa=−0.0019±0.0003, although extended x-ray-absorption fine-structure...
High-resolution x-ray scattering measurements on heavily doped Si:As (5×1021 As cm−3) show lattice compression relative to pure silicon, Δaa=−0.0019±0.0003, although extended x-ray-absorption fine-structure measurements show that the As-Si bond length is 0.06±0.02 Å greater than the usual Si-Si bond length. The overall lattice compression is attributed to increased population of conduction-band states which reduces Si-Si bond lengths. These measurements provide the first direct measurement of the hydrostatic deformation potential for the conduction-band edge in silicon, +3.3±0.7 eV.

The authors investigate the possibility of accelerating the transient simulation of MOS devices by using waveform relaxation. Standard spatial discretization techniques are used to generate a large, sparsely-connected system of algebraic and ordinary differential equations in time. The waveform relaxation algorithm for solving such a system is described, and several theoretical results that characterize its convergence for device simulation are given. One-dimensional experimental results are presented.< >

Monostatic radar equations are reported for laser-transceiver sensors that employ coherent optical detection over a linear-array photodetector. Explicit results are presented illustrating the impact of transmitter and receiver antenna patterns on the heterodyne mixing efficiency achieved by each detector element.

A class of optical computing systems is introduced for solving symbolic logic problems that are characterized by a set of data objects and a set of relationships describing the data objects. The data objects and relationships are arranged into sets of facts and rules to form a knowledge base. The solutions to symbolic logic problems involve inferring conclusions to queries by applying logical inference to the facts and rules. The general structure of an inference machine is discussed in terms of rule-driven and query-driven control flows. As examples of a query-driven inference machine, two hybrid optical system architectures are presented which use matched-filter and mapped-template logic, respectively.
