With three or more cyclic processes competing for the critical section, however, there is a danger of individual starvation when the Pand V-operations are so-called ‘weakly implemented’. When the semaphore operations are weakly implemented and a V(m) is executed, which process is allowed to proceed is left undefined when two or more processes are blocked by P(m). .As a result, there is a danger...

Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...

Introduction The aim of the study was to investigate the state-of-the-art of the performance of critical value reporting and provide recommendations for laboratories setting critical value reporting time frames. Materials and methods The National Centre for Clinical Laboratories in China initiated a critical value reporting investigation in 2015. A questionnaire related to critical value repo...

In this paper, using energy method, small scale effects on the buckling analysis of a double-walled carbon nanotube (DWCNT) under external radial pressure is studied. The constitutive equations derived for a DWCNT using the nonlocal theory of elasticity which Eringen are presented for the first time. By minimizing the second variation of the total energy for a DWCNT, hence, the value of the non...

The internals models amendment to the Basel Accord allows banks to use internal models to forecast Value-at-Risk (VaR) thresholds which are used to calculate the required capital banks must hold in reserves as a protection against negative changes in the value of their trading portfolios. As capital reserves lead to an opportunity cost to banks it is likely that banks could be temped to use mod...

We derive a new lower bound p c > 0:8107 for the critical value of Mandelbrot's dyadic fractal percolation model. This is achieved by taking the random fractal set (to be denoted A 1) and adding to it a countable number of straight line segments, chosen in a certain (non-random) way as to simplify greatly the connectivity structure. We denote the modiied model thus obtained by C 1 , and write C...

Work Rehabilitation and Ergonomics, proactive and reactive, are practices that touch the lives of most employees and employers. Effective, evidence-based services are essential to successful outcomes. With the average age of most workforces now in the mid 40’s, the complications of personal medical conditions affect worker production quality, quantity and job satisfaction. The aging of the “bab...

Similarly to the popular voter model, the Deffuant model describes opinion dynamics taking place in spatially structured environments represented by a connected graph. Pairs of adjacent vertices interact at a constant rate. If the opinion distance between the interacting vertices is larger than some confidence threshold ǫ > 0, then nothing happens, otherwise, the vertices’ opinions get closer t...

In the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using Computational Fluid Dynamics (CFD). Influence of gravity induced sedimentation also has been studied. The commercial software, Fluent 6.2, has been employed to solve the governing equations. A user defined function was added to apply a uniform external ma...
