In a recent paper in this journal Shyur and Shih [1] propose a hybrid MCDM model for strategic vendor selection. In subsection 3.3 (Activity 2), the authors calculate the normalized decision matrix R(=[rij]). They calculate the normalized value rij as follows: rij = fij √ n ∑ j=1 f 2 ij , (1) where j = 1, . . . , n; i = 1, . . . ,m.By virtue of its TOPSIS feature, Eq. (1) is not correct. In...

In the era of technological globalization, educators are encouraged to incorporate online synchronous communication (e.g., chatting) and statistical approaches error-identification automatic annotator) into writing curriculum (Hosseini, 2012; Li, Link, & Hegelheimer, 2014). Electronic feedback is playing an increasingly vital part in modern instruction. It improves learners' revision reduce...

A 3D nyomtatás napjainkban elterjedt módszere az iparnak, a gyógyászatnak és számos más területnek. robbantástechnika is része lehet ennek felsorolásnak, különös tekintettel kumulatív töltetekre. Mivel hadi civil felhasználás vonatkozásában kialakultak átfedések, nem beszélhetünk kizárólag egy területre fókuszált kutatásokról. kialakított tölteteket több méretben eltartással vizsgáltuk. Jelen t...

This paper formalizes the problem of solving multi-sentence algebraic word problems as that of generating and scoring equation trees. We use integer linear programming to generate equation trees and score their likelihood by learning local and global discriminative models. These models are trained on a small set of word problems and their answers, without any manual annotation, in order to choo...
