University hall is an important carrier of information exchange and sharing in higher education campuses, the correct architectural design positioning can improve value university halls. There are many different features use halls urban theaters. This paper investigates feasibility study report indexes projects, analyzes indexes, construction scale functional pre-design period, summarizes some ...

abstract comparative advantage is one of the important economic criterions in production, import and export programming. in this survey, existence and nonexistence of the most important vegetables(potato, cucumber and tomato) comparative advantage in jiroft aria in the year 1385-86 by use of two comparative advantage recognition indexes was determined. the first indexes were social cost benefit...

This thesis defines and designs succinct indexes for several abstract data types (ADTs). The concept is to design auxiliary data structures that ideally occupy asymptotically less space than the information-theoretic lower bound on the space required to encode the given data, and support an extended set of operations using the basic operators defined in the ADT. As opposed to succinct (integrat...

Article history: Received 22 April 2011 Received in revised form 8 April 2013 Accepted 14 April 2013 Available online 23 April 2013 Using a panel dataset of 31 provinces in China, this paper computes the output-oriented Malmquist productivity indexes and their decomposition in China's agricultural sector over the period 1994–2008. In the second-stage regression, which uses the efficiency change...

performance optimization of a single-effect lithium bromide water absorption refrigerationsystem is the subject of this paper. first, the thermodynamic model of the system wasderived based on thefirst and second law analysis of an absorption refrigeration cycle with libr-water as the working fluid pair.then, the effects of different design parameters such as the generator inlet hot water temper...

Clustering (or cluster analysis) has been used widely in pattern recognition, image processing, and data analysis. It aims to organize a collection of data items into c clusters, such that items within a cluster are more similar to each other than they are items in the other clusters. The number of clusters c is the most important parameter, in the sense that the remaining parameters have less ...

The occurrence of zoosporangia and oospores is analyzed for 88 field populations of Phytophthora infestans (Mont.) de Bary in Moscow region and other regions of Russia from 1997 to 2006. For estimation of zoosporangia and oospore frequencies in the populations, the indexes IZ (for zoosporangia) and IO (for oospores) are suggested. The combinations of these indexes enabled a reveal of 4 strategi...

Data variety, as one of the three Vs of the Big Data, is manifested by a growing number of complex data types such as documents, sequences, trees, graphs and high dimensional vectors. To perform similarity search on these data, existing works mainly choose to create customized indexes for different data types. Due to the diversity of customized indexes, it is hard to devise a general paralleliz...

Space filling curves (SFCs) are widely used in the design of indexes for spatial and temporal data. Clustering is a key metric for an SFC, that measures how well the curve preserves locality in moving from higher dimensions to a single dimension. We present the onion curve, an SFC whose clustering performance is provably close to optimal for cube and nearcube shaped query sets, irrespective of ...

Teaching quality evaluation system is a multi-level and multi-target complex issue, with numerous evaluation indexes, and to take all evaluation indexes as input of neural network would cause complex structure of neural network, thus affecting the performance of teaching quality evaluation system. This paper has proposed a teaching quality evaluation method based on AHP-BPNN. Firstly, the AHP i...
