optimization of the exploitation operation is one of the most important issues facing the mining engineers. since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. the aim of this optimization is to maximize the net present value (npv). since the objective function of this problem is non-linear, three methods can b...

diversion dams in order to raise the water level of river and conveys of water into the main canal irrigation network is designed. if the dimensions of different parts of the diversion dam be considered large, stability will be supplying, but due to the increase volume of materials, construction costs will be more. design engineer must choose sections of dam that had least amount of materials a...

The goal of this study is to investigate the effect of actuator position on the theoretical energy consumption of an electrically powered bipedal robot. Specifically, the study focuses on the legs of the afore-mentioned robot because their function is limited, as they are primarily used for either locomotion or standing, and thus, this is suitable for optimization. Furthermore, the hip and knee...

BBN submitted system combination outputs for Czech-English, German-English, SpanishEnglish, and French-English language pairs. All combinations were based on confusion network decoding. The confusion networks were built using incremental hypothesis alignment algorithm with flexible matching. A novel bi-gram count feature, which can penalize bi-grams not present in the input hypotheses correspon...

Nowadays, with extending applications of bi-layer metallic sheets in different industrial sectors, accurate specification of each layer is very prominent to achieve desired properties. In order to predict behavior of sheets under different forming modes and determining rupture limit and necking, the concept of Forming Limit Diagram (FLD) is used. Optimization problem with objective functions an...

In this paper, instead of the classical approach to the multi-criteria location selection problem, a new approach was presented based on selecting a portfolio of locations. First, the indices affecting the selection of maintenance stations were collected. The K-means model was used for clustering the maintenance stations. The optimal number of clusters was calculated through the Silhou...

The radio stripe (RS) system is a practical implementation of cell-free mMIMO, in which set multi-antenna access points (APs) serves at the same time-frequency resources user equipment (UE) network. APs are sequentially connected stripe, sharing fronthaul link to central processing unit. This work considers an uplink power optimization problem that aims enhance network spectral efficiency (SE) ...

The spin-orbit scattering ~SOS! of the Pb and Bi impurities in Cs, K, and Na films is measured by means of weak localization. The dimensionless SOS cross section for Pb in Cs ~in units of 4p/kF 2 ! has the large value of sso *' 2 3 . This SOS cross section is the absolute maximum possible for ~s,p! impurities ~if one neglects d and larger l scattering!. The SOS contributes almost 50% to the tot...

BACKGROUND We aimed to apply collaborative business intelligence (BI) system to hospital supply, processing and distribution (SPD) logistics management model. METHODS We searched Engineering Village database, China National Knowledge Infrastructure (CNKI) and Google for articles (Published from 2011 to 2016), books, Web pages, etc., to understand SPD and BI related theories and recent researc...
