A deep understanding of household appliance standby energy use (SEU) and associated saving potentials in Chinese rural areas is vitally important due to the huge amounts of households and appliances. However, to date, few study has been conducted and very little is known about the SEU. Meanwhile, existing methods of estimating such saving potentials have two limitations. Firstly, they primarily evaluated...
Data Mining is to pick up unknown, potential and useful information from vast, incomplete, noisy, vague and random data. Association Rules analysis is frequently used in data mining that analyze data and find the association or contact between things. This paper applies the Association Rules to the analysis of relationship between casualty and residential environment in earthquake. The data comes...
The Walsh spectrum of m-resilient Boolean function at any point is divisible by 2m+2. This property is proved by two new methods in this work, which differ from the known method presented by Maitra. The first method is to compute the Walsh spectrum of resilient Boolean function, which is straightforward compared to the Maitra's method. The second method is to induce the number of variables and the...
As a common generalization of matchings and matroid intersection, Cunningham and Geelen introduced the notion of path-matchings in 1996. Let K1,t denote the star with t + 1 vertices. A graph is K1. t-free if G contains no K1, t, as its induced subgraph. Sumner showed that (t - 1)-connected K1, t-free graphs with even number of vertices have a perfect matching. In this paper, some sufficient conditions...
The generalized minimum vertex-biconnected network problem plays an important role in the design of survivable backbone networks that should be fault tolerant to single component outage. When given a graph where the nodes are partitioned into clusters, the goal is to find a subgraph of minimum costs that connects exactly one node from each cluster in a vertex-biconnected way.We present a memetic algorithm...
Energy conservation, coverage and connectivity are three critical application requirements in wireless sensor networks. Related researches have either concerned coverage, connectivity, and energy conservation separately or required sensing/communication range restrictions. In this paper, we aim to maximize the network lifetime, while maintaining coverage and connectivity simultaneously, without any...
With the development of Web service technology, it gives us a chance to solute the difficult problem in spatial information sharing. This paper proposes a service-oriented model, named SISM (Spatial Information Sharing Model). This model includes three aspects: (1) a service-oriented architecture, which comprises the Geographical Services Bus layer and the Geographical Data Bus layer, is adopted to...
One of the main problems of normative system implementation is the semantic gap between the abstract norms described by natural language and the concrete norms described by operational language. This paper introduced an autonomous layered normative system framework which divided the normative system into three different layers. In this framework we realized automatic norm refinement by setting up...
Dense subgraphs of protein interaction networks are believed to be potential protein complexes and play an important role in analyzing cellular organization and predicting functions of proteins. In this paper, we present a new algorithm LD-Miner for mining l-dense subgraphs in protein interaction networks. We apply algorithm LD-Miner to the protein interaction network of Saccharomyces cerevisiae collected...
Mental health represents a social and economic problem in all European Union (EU) member nations. Although cognitive behavioral therapies (CBT) have provided an effective approach to the treatment of depression, several issues currently remain unresolved. This paper introduces a novel mobile system that provides several useful functions to improve the delivery of treatments for depressive conditions...
In the paper, a new parallel LZW-Like algorithm, bi-directory LZW algorithm (BD-LZW) will be interpreted. The new algorithm can be used in data compression/decompression system which runs on multi-microprocessor system, such as CELL, which the algorithm will be implemented on. Different from the conventional parallel LZW algorithm with one input directory, BD-LZW algorithm allows two threads reading...
