U-shaped tight curvatures in optical fibers lead to resonant couplings between the fundamental and higher order modes that are sensible different parameters, such as strain or temperature, for example. The response of sensor consists on shift wavelength coupling. In case singlemode fibers, coupling involves a so-called “cladding mode” and, due its evanescent field, curved region will be changes...

MEMS are used in acceleration, flow, pressure and force sensing applications on the micro macro levels. The fundamental part of every sensor is transducer which converts measurend intrest into interpretable output signal. most prominent piezoresistive cantilever translates any signal an electrical signal.This paper presents deisgn fabrication U shaped with enhanced sensitivity stiffness gives b...

Skin lesion segmentation is an essential step toward accurate skin diagnosis. The need to automate on the one hand, and challenges it faces, other have made a growing area of research focus. Automation helps reduce effort time needed for diagnosis treatment make better utilization available data shared experiences. faced by automation can be broadly defined (but not limited to); variations in t...

Even today the investigation of U-shaped functions in human development is of considerable importance for different domains of Developmental Psychology. More and more scientific researchers focus their efforts on the challenge to describe and explain the phenomenon by identifying those skills and abilities being affected. The impact of U-shaped functions on diagnostic decision-making and on the...

The assembly line balancing problem is a non deterministic polynomial type planning problem for mass production. Layout design changes constitute a major decision that yields investment for assembly operations and numerous heuristics have been reported in the literature for solving the line balancing problems. U-shaped assembly layout offers several benefits over traditional straight-line layou...

At and above the level of the inferior colliculus (IC), some neurons respond maximally to a limited range of sound durations, with little or no excitatory response to durations outside of this range. Such neurons have been termed "duration tuned" or "duration selective." In this study we examined the effects of varying signal amplitude on best duration, width of tuning, and first spike latency ...

BACKGROUND Results of studies concerning the association between obesity and depression are conflicting. Some find a positive association, some a negative association and some find no association at all. Most studies, however, examine a linear association between Body Mass Index (BMI) and depression. The present study investigates if a nonlinear (U-shaped) trend is preferable over a linear tren...

In this paper, the typical U-shaped pieces were taken as the object of study and the finite element numerical simulation software Dynaform is applied to simulate the effect of sheet metal bending. The U-shaped bending spring back and its thickness change are analyzed. The influence law of main parameters of die structure to sheet thickness change and the spring back amount are obtained by combi...

The occurrence of U-shaped dose-response relationships (often termed hormesis) has been documented in numerous biological, toxicological, and pharmacological investigations. Many of the endpoints studied are of considerable significance to public health (e.g. body weight, cholesterol levels, ethanol consumption, longevity, cancer incidence, etc). Despite the fact that U-shaped dose-responses ar...
