This paper studies some geometric aspects of indistinguishability operators (also called similarities and fuzzy equivalences). Concretely, it will be focused on the (geometric) group associated to a T-indistinguishability operator E on X (i.e., the group of all bijective maps h : X 4 X such that E ( x , y) = E(h(x) , h(Y)) b'x, Y E XI. The cases for E being one-dimensional and invariant under t...

In this paper, we study the two following minimization problems: S0(q, φ) = inf u∈H2 0 (Ω),‖u+φ‖q=1 ∫ Ω | u|2 and Sθ (q, φ) = inf u∈H2 θ (Ω),‖u+φ‖q=1 ∫ Ω | u|2. We prove that for a class of maps φ, we have Sθ (q, φ) < S0(q, φ) and for another class, we have Sθ (q, φ) = S0(q, φ). c © 2005 Elsevier Ltd. All rights reserved.

Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...

• A review of CO 2 thickening as promising technology for oilfield application. Specific thickeners eliminate viscous fingering and gravity segregation issues. have been categorized into five types, depending on chemical nature. Thickening methodology was described to attain optimal viscosity solubility traits. It is necessary develop effective thickeners, while considering cost toxicity. The r...

Aim: Infant regurgitation and distress are common but are a major cause of parental anxiousness. The efficacy of dietary management is contradictory. Material and Methods: Twelve exclusively formula fed infants crying for more than 3 hours/day since at least 3 weeks and regurgitating several times after each feeding were enrolled in a double blinded cross-over intervention trial with two innova...
