In this paper, we study the so-called PageRank algorithm used at Google that determines the importance of each webpage. We first provide a brief overview of this algorithm. Then, we consider the problem of computing the changes in PageRank values when the web data contains erroneous link information. Based on interval matrix techniques, we develop an efficient centralized algorithm using linear programming...
This paper discusses a portfolio selection problem with type-2 fuzzy future returns involving interval numbers considering the investor's subjectivity. Since this proposed problem is not well-defined due to primary and secondary fuzziness, introducing the possibility measure that the total return is more than the target value, the main problem is transformed into the type-1 fuzzy programming problem...
It is well known that the massage therapy is useful for the rehabilitation of various diseases (i.e. oral health problems, etc.). Although various apparatus have been developed for the massage of the torso and limbs, a machine to perform precise massage therapy to maxillofacial region is not developed yet. The ability of a robotic system to exert itself without fatigue aims in providing more hours...
This study aims to propose a simple calculation method considering road network factors and summarized into 6 indexes for evaluation. Shin-hua Township in Tainan County is selected for case study. Firstly, factor analysis is used for the key factors affecting shelter safety and cluster analysis is taken for attributes classification. Then the final results with quantified indexes are showed in GIS...
