This paper presents a rapid localization method for mobile robots. Localization, i.e., absolute position measurement, is an important issue since odometer errors render it impossible for any robot to precisely follow a speci ed trajectory, resulting in a growing di erence between the actual con guration and the calculated con guration as the robot travels. Periodic localization is required to c...

1 Processor Array Design with FPGA Area Constraint Joseph A. Fernando, Jack S.N. Jean Abstract|Digital signal processing algorithms with multiple shift-invariant dependence graphs (DGs) can be mapped to FPGA hardware in many di erent types of systolic processor arrays. Because of the nite amount of hardware resources, the problem is to use a \right" amount of hardware in a speci c con guration ...

Properties of a novel conŽ guration of an optical (spatio-temporal) pulse compressor, that is based on a Kerr-type planar waveguide into which two pulses are simultaneously launched, are studied. It is assumed that the pulse which is the subject of the compression propagates in the anomalous dispersion regime, while the auxiliary pulse is in normal dispersion. The best parameters of the propose...

Multilevel petrinets are proposed for facilitating exible modeling and control of complicated dynamic processes, especially autonomous, learning and intelligent systems. A metapetrinet is able not only to change the marking of a petrinet but also to recon gue dynamically its structure. Each level of the metanet is an ordinary petrinet of some traditional type. A basic level petrinet simulates t...

Experience in applying expert systems revealed that there is usually a signi cant gap between the problem in the expert's mind and its formal speci cation. Thus, real-world con guration and scheduling problems often require a close dialogue between an expert and the expert system during the con guration process in order to bridge this gap. The expert must be able to re ne and correct the proble...

WASMII, a virtual hardware system that executes data ow algorithms, is based on an MPLD, an extended FPGA with multiple sets of con guration SRAM. Although we have developed an emulation system and software environment for WASMII, it has tended to be unrealistic due to the di culty of the MPLD implementation. However, with recent technologies of semiconductors, an FPGA and DRAM can be implement...

Current internet technology doesn't solve the following three con guration problems for corporate networks: insulating a network located in the depths of a private network from the Internet, wasting Internet address space behind a rewall, and the lack of security in communication between corporations. This paper proposes a versatile tunneling model called \DDT" in order to give solutions for th...

Quality of service (QoS)-enabled component middleware can help reduce the complexity of deploying and con guring QoS aspects, such as priorities and rates of invocation. Few empirical studies have been conducted, however, to guide developers of distributed real-time and embedded (DRE) systems in choosing among alternative designs and performance optimizations. Moreover, few empirical studies ha...

Random sampling strategies play critical roles in randomized motion planners, which are promising and practical for motion planning problems with many degrees of freedom (dofs). In this paper, we address random sampling in a constrained con guration space { the contact con guration space between two polyhedra, motivated by the need for generating contact motion plans. Given a contact formation ...

The organization of the knowledge base for monitoring and the related principles for knowledge representation are presented. The knowledge base consists of conguration, sensor, dynamic and statistical databases. The con guration database represents the system architecture of the network. The sensor database is set up based on the sensor con guration in the network. The dynamic database represen...
