This paper presents a method for determining the network lines and buses where the occurrence of faults will lead to voltage sags causing severe financial losses in the power system. The proposed method is based on a typical stochastic assessment of voltage sags. The network regions where fault occurrences will simultaneously lead to voltage sags at different sensitive load points can be determ...

This study analyzes a barrier of developing Exchange named lack of information related to performance of organization. This paper proposes a combined approach to decision making that Examine companies financial performance and offers an optimal way to solve the problem of ranking and efficiency survey. FAHP-TOPSIS approach is used to rating companies and FAHP-DEA approach is used for efficiency...

ranking of companies listed on the exchange represent their status and considered a criterion for investment. also, it increases market's competition, development and efficiency. in this study, the fifty superior companies listed in tehran stock exchange were ranked based on financial ratios (liquidity, operational, leverage and profitability) using fahp- ftopsis hybrid approach during the...

Ranking of companies listed on the exchange represent their status and considered a criterion for investment. Also, it increases market's competition, development and efficiency. In this study, the fifty superior companies listed in Tehran Stock Exchange were ranked based on financial ratios (liquidity, operational, leverage and profitability) using FAHP- FTOPSIS hybrid approach during the year...

This paper describes the approaches and results of our system for the NTCIR-10 INTENT task. We present some methods for Subtopic Mining subtask and Document Ranking subtask. In the Subtopic Mining subtask, we employ a voting method to rank candidate subtopics and semantic resource HowNet was used to merge those candidate subtopics which may impact diversity. In the Document Ranking Subtask, we ...

Let S be a dataset of n 2-dimensional points. The top-k dominating query aims to report the k points that dominate the most points in S . A point p dominates a point q iff all coordinates of p are smaller than or equal to those of q and at least one of them is strictly smaller. The top-k dominating query combines the dominance concept of maxima queries with the ranking function of top-k queries...

This paper introduces a qualitative ranking function that uses signed integers to describe the surprise associated with the occurrence of events. The measure introduced, κ, is based on the κ calculus but differs from it in that its semantics enable an explicit representation of complements. As a result, the κ is more capable of enforcing probability theory-like constraints to carry on reasoning.

This paper describes our participation in the Intent Mining track of NTCIR-11. We present our methods and results for both document ranking and subtopic mining. Our ranking methods are based on several data fusion techniques with some variations. Our subtopic mining method is a very simple technique that uses query dimensions’ items to form a subtopic

We describe our participation in the subtopic mining and document ranking subtasks of the NTCIR-9 Intent task, for both Chinese and Japanese languages. In the subtopic mining subtask, we experiment with a novel data-driven approach for ranking reformulations of an ambiguous query. In the document ranking subtask, we deploy our state-ofthe-art xQuAD framework for search result diversification.
