An analogue-VLSI winner-take-all circuit is enhanced through the addition of hysteretic feedback that emphasizes the spatial locality of competing signals using a resistive network. This circuit has application to tasks in areas such as image processing, in which inputs are not stationary with respect to the circuit array. Introduction Analogue VLSI circuits facilitate the implementation of low...

The article discribe methods of verifing the conditions of access in computer systems based on Take-Grant protection model.

Weighted committee games generalize n-player simple voting games to m ≥ 3 alternatives. The committee’s aggregation rule treats votes anonymously but parties, shareholders, members of supranational organizations, etc. differ in their numbers of votes. Infinitely many vote distributions induce only finitely many distinct mappings from preference profiles to winners, i.e., non-equivalent committe...

a gas permeation model (coupling model) has been developed which has the flexibility to be used for different membrane module configurations. the aim of this work is to predict the performance of a single stage gas separation process using membranes and provide a comprehensive description of process parameters like flow rates, composition, stage cut and stream pressure. the significant feature ...

Hospital Acquired Infections (HAIs) are a global concern as they impose significant economic consequences on the healthcare systems. In the U.S. alone, HAIs have cost hospitals an estimated $9.8 billion a year. An effective measure to reduce the spread of HAIs is for Health Care Workers (HCWs)to comply with recommended hand hygiene (HH) guidelines. Unfortunately, HH guideline compliance is curr...
