A phenomenological two-fluid model of the (time-reversible) spectrally-truncated 3D Euler equation is proposed. The thermalized small scales are first shown to be quasi-normal. The effective viscosity and thermal diffusion are then determined, using EDQNM closure and Monte-Carlo numerical computations. Finally, the model is validated by comparing its dynamics with that of the original truncated...

Abstract If the sample or population has vague, inaccurate, unidentified, deficient, indecisive, fuzzy data, then available sampling plans could not be suitable to use for decision-making. In this article, an improved group-sampling plan based on time truncated life tests Weibull distribution under neutrosophic statistics (NS) been developed. We developed single and double NS. The proposed desi...

The present study proposed a new modified group chain sampling plan for truncated life test when the lifetime of products follow Kumaraswamy generalized power Weibull (KGPW) distribution. results optimal size, mean ratio true to specified mean, operating characteristic values, minimum angles, acceptance quality level, lower level are obtained against producer’s, consumer’s risk, termination tim...

The two-parameter Weibull distribution is the predominant distribution in reliability and lifetime data analysis. The classical approach for estimating the scale [Formula: see text] and shape [Formula: see text] parameters employs the maximum likelihood estimation (MLE) method. However, most MLE based-methods resort to numerical or graphical techniques due to the lack of closed-form expressions...

Abstract: Problem statement: We studied the inventory-production system with two-parameter Weibull distributed deterioration items. Approach: The inventory model was developed as linear optimal control problem and by the Pontryagin maximum principle, the optimal control problem was solved analytically to obtain the optimal solution of the problem. Results: It was then illustrated with the help ...

volume estimation of most agricultural products using mathematical methods is not accurate because of their irregular shape. an alternative method is image processing, which can be used in continuous sorting machines. the objective of this study is to find a practical method for volume estimation of potatoes using image processing. fifty potatoes (marfona variety) were selected as experimental ...

Today , when operation of commercial plants is organised, they are expected to comply constantly increasing requirements for safety, dependability and efficiency operation. The methods procedures that employed the purpose improving safety based on information components, systems equipment. In order identify objective characteristics such facilities, their behaviour in monitored. course facility...

The dominance of the major transcript isoform relative to other isoforms from the same gene generated by alternative splicing (AS) is essential to the maintenance of normal cellular physiology. However, the underlying principles that determine such dominance remain unknown. Here, we analyzed the physical AS process and found that it can be modeled by a stochastic minimization process, which cau...
