E-alliance is the union of e-commerce and its success and efficiency is related to comprehensive quality of e-commerce. Thus, ranking e-commerce websites in e-alliance is of importance, which is a multi-criteria decision-making (MCDM) problem. This paper proposes an evaluation model based on analytic hierarchy process (AHP), fuzzy sets and technique for order performance by similarity to ideal ...

The interstitial nucleus of Cajal (INC) is thought to control torsional and vertical head posture. Unilateral microstimulation of the INC evokes torsional head rotation to positions that are maintained until stimulation offset. Unilateral INC inactivation evokes head position-holding deficits with the head tilted in the opposite direction. However, the underlying muscle synergies for these oppo...

This paper pre sents a new algorithm for constructing fuzzy de cision tree s from relational database systems and gene rating fuzzy rule s from the constructed fuzzy de cision tre es. We also pre sent a me thod for dealing with the comple tene ss of the constructed fuzzy decision tree s. Based on the gene rated fuzzy rule s, we also pre sent a method for e stimating null values in re lational d...

Motor training results in encoding of motor memories, a form of use-dependent plasticity. Here we tested the hypothesis that transcranial magnetic stimulation (TMS) synchronously applied to a motor cortex engaged in a motor training task could enhance this plastic process. Healthy volunteers were studied in four sessions: training consisting of performance of directionally specific voluntary th...

In the present paper, we introduce and study a fuzzy vector equilibrium problem and prove some existence results with and without convexity assumptions by using some particular forms of results of textit{Kim} and textit{Lee} [W.K. Kim and K.H. Lee, Generalized fuzzy games and fuzzy equilibria, Fuzzy Sets and Systems, 122 (2001), 293-301] and textit{Tarafdar} [E. Tarafdar, Fixed point theorems i...

Os efeitos da variação da concentração da amostra nos valores de deslocamento químico e nas velocidades de relaxação spin-rede seletiva (R1 ) e não seletiva (R1 ) foram medidos em solução para os três isômeros das guanil hidrazonas derivadas do nitrobenzaldeído (NBGH) puros e com a albumina do soro bovino (BSA). Os resultados foram usados para determinar o tempo de correlação (τc), mostrando qu...
