In order to evaluate the graduates attending second-round examination objectively, this study established graduate second-round examination evaluate system based on Analytic Hierarchy Process (AHP) and Fuzzy comprehensive evaluation method. Evaluation indexes in the system included knowledge structure, scientific research ability and comprehensive quality of graduates attending second-round exa...
This paper demonstrates the advantage of combining a ranked output from a fulltext index and another from an index generated using generic summary texts. Our main ndings are as follows: (1) The combination of a fulltext-based run and a summary-based run can signi cantly outperform either alone, especially when the fulltext evidence is emphasized. (2) The primary role of the summary index in the...
This paper considers the problem of how to construct price indexes on a panel data set. First a suitable panel data set is constructed by merging Eurostat’s Harmonized Index of Consumer Prices (HICP) with a cross-section of OECD data. Second, seven different methods for constructing price indexes on a panel are proposed. These are then applied to the merged HICP/OECD data set. Temporal and spat...
This paper explores an evaluation method to evaluate the performance of participants in electric power emergency drill, expounds various important activities and summarizes general mode drill. introduces principle factor analysis principal component method, then uses this find common factors a series indexes, finally takes score as directly. comprehensive can reduce number indexes by looking fo...
Reliability of heart rate variability in healthy older women at rest and during orthostatic testing.
BACKGROUND AND AIMS In the older population, the reliability of heart rate variability (HRV) has only been evaluated in a few studies, in the supine position, and covering a broad sample of age and patients of both sexes. To document the relevance of using HRV analysis in healthy older women, the aim of this study was to evaluate the reliability of HRV indexes during three classical tests. ME...
Managers realized that knowledge has an important role in attaining their competitive edge and strategic goals. Therefore, knowledge management (KM) implementation has become a main challenge for the managers. Lack of proper infrastructures and prerequisite, may cause failure on the successful application of knowledge management. In this paper, based on literature review, proper factors for imp...
The aim of this study is to propose a new target recognition method for the multi-sensor with multiple characteristics indexes. Coefficient of variation is used to determine the weights of characteristic indexes. The conceptions of ideal optimal and negative ideal vectors are given first and then normalized relative ratio is used to comprehensive evaluation value. Hence the rule of target recog...
Quality assessment in clustering is a long-standing problem. In this contribution we describe some indexes to measure properties of clusterings, taking advantage of the added flexibility provided by fuzzy paradigms. We first present an approach to evaluate some indicators of quality of an individual clustering, by analyzing the co-association matrix. Then we describe a technique to evaluate the...
