FPGA fault repair schemes remove faulty elements from designs through reconfiguration. In designs with high FPGA utilization, a sufficient number of routable faultfree elements may not be available for permanent fault repair. We present a new permanent fault repair scheme, in which the original design is reconfigured into another fault tolerant design that has smaller area, so the damaged eleme...

In opinion of substructure cascade, multimode feed network is composed of impedance transforming substructure and isolating substructure. Starting from the characteristic of the substructure in multimode feed network, a method of measurement for its three-port scatter parameters of substructure is presented, based on the applying of the available two-port vector network analyzer (VNA), consider...

A key challenge in the SAD phasing method is solving a structure when the anomalous signal-to-noise ratio is low. A simple theoretical framework for describing measurements of anomalous differences and the resulting useful anomalous correlation and anomalous signal in a SAD experiment is presented. Here, the useful anomalous correlation is defined as the correlation of anomalous differences wit...

Most impact tests are carried out on specimens with specific stacking sequence and dimensions to meet standard and experimental limitations. The damaged areas and the resulted reduction in the strength values of specimens may not agree very well with those of real application. In this paper an attempt is made to study the variation in the size of damaged areas due to varying the dimension of te...

The symbolic value partition problem is more general than the reduct problem and more complicated than the discretization problem. In this paper, we point out that the symbolic value partition problem can be converted into a series of reduct problems and propose an algorithm called reduction based symbolic value partition (RBSVP) whose all possible outputs form the set of all partition reducts....

The organization of efferent neurons in area 19 of the cat was examined by bulk injections of retrograde tracers, WGA-HRP and CTX-Au, into extrastriate area 21a. In one case, the cortex was cut coronally and retrogradely labeled cells in area 19 were present in columnar register throughout layers 2 to 6, with the majority of labeled cells in layers 2/3. The number of columns per tissue section ...
