In this contribution we develop a theoretical statistical approach to predict the acceptable bandwidth tolerances for optical filter cascades in wavelength division multiplexing (WDM) networks. We also establish tolerances for the center frequency misalignments considering a statistical approach presented in a previous work. The optical filters analyzed have a trapezoidal shape, and different b...

This paper proposes a method for analog fault diagnosis using neural networks. The primary focus of the paper is to provide robust diagnosis using a mechanism to deal with the problem of component tolerances and reduce testing time. The proposed approach is based on the k-fault diagnosis method and artificial backward propagation neural network. Simulation results show that the method is robust...

In patients with hypertension and other diseases treated with thiazide derivatives for hypotensive and diuretic purposes, we observed decreased glucose tolerances in comparison with those before treatment. When thiazide diuretics were withdrawn, glucose tolerances were found to recover rapidly to normal. Oral tolbutamide test in these cases showed the blood sugar response curves between those i...

The paper deals with a generalization of the notion of partition for wider classes of binary relations than equivalences: for quasiorders and tolerance relations. The counterpart of partition for the quasiorders is based on a generalization of the notion of equivalence class while it is shown that such a generalization does not work in case of tolerances. Some results from [5] are proved in a m...

CAD model repair is often a necessary precursor to mesh generation, due primarily to the inconsistencies between the tolerances used by the designer and the tolerances required by the analyst. This paper presents a method for meshing directly on imperfect CAD models without needing to repair the model. This is done via a hierarchical grid topology structure that defines a surface grid by a mesh...
