A two-port memory contains two similar ports, which can be accessed separately and independent of each other. In this paper, logical fault models are derived for the effect of shorts between the ports. The result is a set of new fault models, based on circuit simulation, together with a new test.

A command-and-control information system (CCIS) is a military application that provides information to be used by a commander. The use of a single CCIS is rather easy. However, the operation becomes much more complex when several CCISs, generally distributed and heterogeneous, are required. As a solution, we intend to set up software agents that support the interoperability of these CCISs. The development and management of these agents are based on two different concepts, namely mobility and workflow. This research is part of the IC2IS (Interoperable Command and Control Information Systems) project.

This paper presents the results of 44 well known memory tests applied to 1896 1M*4 DRAM chips, using up to 96 different stress combinations with each test. The results show the importance of selecting the right stress combination, and that the theoretically better tests (i.e. those covering different functional faults) also have a higher fault coverage. However the currently used fault models still leave much to be explained; e.g., the used data backgrounds and address orders show an unexplainable large variation in fault coverage.
The main issue addressed in this paper is how to simultaneously involve several information sources (ISs) to satisfy users' needs. These ISs are distributed on networks and may present several incompatibilities at...

A new method of incorporating local image constraints into blind image restoration is proposed. The local mean and variance of the degraded image are used to obtain .in initial estimate of the pixel intensity bounds. As the restoration proceeds, the bounds are updated from the current image estimate. I lie iterative-bound algorithm shows an improvement over the use of fixed bounds taken from the blurred image, in which case underestimation of the variance occurs at edges and textures. Simulations are presented for both the fixed-And iterative-bound implementations.

We, in this paper, generate test cases of the wireless protocol that is used as air interface in IMT-2000 by means of the test generation tool based on protocol specifications as Petri Nets. So, we can perform conformance testing of IMT-2000 system. In order to support a good understanding and diagnose dynamic behavior of IMT2000 system, we try to do specification and validation using Petri Nets modeling. In addition to, do modeling whole system and modeling independently each channels of IMT-2000 system. And, analyze performance by these modeling.

Testing two-port memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well as the test strategy. This paper discusses the consequences of the port restrictions (read-only or write-only ports) on the tests; in addition it covers the test strategy for address decoder faults in two-port memories.

Testing two-port memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible fault models, the tests for single-port and two-port memories, as well as the test strategy. This paper presents a test strategy for two-port memories and covers the consequences of the port restrictions (read-only or write-only ports).
