Supplier selection and order allocation decisions are the main parties of a supply chain network which has high impact on economic performance this network. This study using an Economic Order Quantity (EOQ) concept proposes optimization model for integrated supplier problem where lot sizing, discounts, disruptions contributed among first studies in research area. To address uncertainty, scenari...

We present a method to deal with adaptive noise cancelling based on independent component analysis (ICA). Although popular least-mean-squares (LMS) algorithm removes noise components based on second-order correlation, the proposed ICA-based algorithm can utilize higher-order statistics. Additionally, extending to transform-domain adaptive filtering (TDAF) methods, normalized ICA-based algorithm...

Abstract—Nowadays, the use of renewable energy sources has been increasingly great because of the cost increase and public demand for clean energy sources. One of the fastest growing sources is wind energy. In this paper, Wind Diesel Hybrid System (WDHS) comprising a Diesel Generator (DG), a Wind Turbine Generator (WTG), the Consumer Load, a Battery-based Energy Storage System (BESS), and a Dum...

Increased running speeds and the requirement for rotating machinery to operate within specified levels of vibration mean that the control of machinery vibration is essential in today’s industry. In this work, the flexible rotor balancing problem based on the influence coefficient method and holospectrum technique is formulated as a minimax optimization problem. This formulation can solve the mi...

Monitoring a set of targets and extending network lifetime is a critical issue in wireless sensor networks (WSNs). Various coverage scheduling algorithms have been proposed in the literature for monitoring deployed targets in WSNs. These algorithms divide the sensor nodes into cover sets, and each cover set can monitor all targets. It is proven that finding the maximum number of disjointed cove...

In this paper, the optimal design of supplementary controller parameters of a unified power flow controller (UPFC) to damp low-frequency oscillations in a weakly connected system is investigated. The individual design of the UPFC controller, using the imperialist competitive algorithm (ICA) technique over a wide range of operating conditions, is discussed. The effectiveness and validity of the ...

Investors always pay attention to the two factors of return and risk in portfolio optimization. There are different metrics for calculation factor, among which most important one is Conditional Value at Risk (CVaR). On other hand, Data Envelopment Analysis (DEA) can be used form optimal evaluate its efficiency. In these models, created by stocks or companies with high Since search space vast ac...

Cooperative spectrum sensing (CSS) in cognitive radio (CR) has been widely investigated to be considered as a spectrum scanning mechanism that allows secondary users or cognitive radio users (SUs) to use detected spectrum holes caused by primary users (PUs) absence. This paper focuses on optimality of analytical study on the common soft fusion (SDF) CSS based on different iterative algorithms w...

An immunochromatographic assay (ICA) based on competitive antigen-coated format using colloidal gold as the label was developed for the detection of the organophosphorus insecticide chlorpyrifos. The ICA test strip consisted of a membrane with a detection zone, a sample pad and an absorbent pad. The membrane was separately coated with chlorpyrifos Hapten-OVA conjugate (test line) and anti-mouse...
