Open vehicle routing problem (OVRP) is a hot research topic in modern operational research, compared with classical VRP problems, one of its marked characteristics is that the vehicle can choose the other distribution center as an end after the completion of the transportation service. The solving goal of OVRP is to build a Hamiltonian path to meet the needs of all customers. In order to solve ...

BACKGROUND A high homocysteine concentration is a potential risk factor for cardiovascular disease that can be reduced through betaine supplementation. Choline is the precursor for betaine, but the effects of choline supplementation on plasma total homocysteine (tHcy) concentrations in healthy humans are unknown. OBJECTIVE The objective was to investigate whether supplementation with phosphat...

Delamination of the veneering composite is frequently encountered with fibre-reinforced composite (FRC) fixed dental prosthesis (FDPs). The aim of this study is to evaluate the influence of framework design on the load-bearing capacity of laboratory-made three-unit inlay-retained FRC-FDPs. Inlay-retained FRC-FDPs replacing a lower first molar were constructed. Seven framework designs were evalu...

Research software involving stochastic behaviour often requires an enormous quantity of random numbers. In addition to the quality of the pseudorandom number generator (PRNG), the speed of the algorithm and the ease of its implementation are common practical aspects. In this work we will discuss how to optimize the access speed to random numbers independently from the generation algorithm using...

this study aims to undertake a statistical study to evaluate the accuracy of nine models that have been previously proposed for estimating the ultimate resistance of plate girders subjected to patch loading. for each model, mean errors and standard errors, as well as the probability of underestimating or overestimating patch load resistance, are estimated and the resultant values are compared o...

The HL-Reliability Index is utilized to investigate the applicability of several linear and nonlinear response surface models based on design experiments techniques evaluate safety under random loading, against bearing capacity failure shallow foundations resting c-φ soils with multivariate correlated variables. reliability results obtained using FORM/SORM coupled these models, are checked by M...

In this paper, we present the Anderson-Darling (AD) and Kolmogorov-Smirnov (KS) goodness of fit statistics for stationary and non-stationary random fields. Namely, we adopt an easy-to-apply method based on a random projection of a Hilbert-valued random field onto the real line R, and then, applying the well-known AD and KS goodness of fit tests. We conclude this paper by studying the behavior o...

In this paper, the authors present implementation of a number of low power FIR filter architectures to design reuse-able, programmable and parameterized soft FIR filter IP Cores and compare their performance in terms of area and power. An overall 22.1% power saving is achieved. The paper provides an analysis of the programmable cores and the impact of their constituent components on the overall...
