The paper examines the developmental status of four of the next candidate countries’ information infrastructures for accession into the European Union (EU). It develops significant relationships between nations’ levels of information infrastructure development and their economic and social developments, and applies these relationships to evaluate investment needs for a select group of accession...

In this paper, a level set analysis is proposed which aims to analyze the S&P 500 return with a certain magnitude. It is found that the process of large jumps/drops of return tend to have negative serial correlation, and volatility clustering phenomenon can be easily seen. Then, a nonparametric analysis is performed and new patterns are discovered. An ARCH model is constructed based on the patt...

An efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. The implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. According to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses Fuzzy Inference Systems to select cluster head. The alg...

. in order to study the variation for seed yield and its components, 200 accessions of alfalfa (medicago sativa l.) were sown as drilled plots, using alpha designs/unreplicated with two repeated entries with in all of 10 blocks under dry land farming system in kabodarahang research station, hamadan, iran, during 2010 to 2011. data were analyzed for descriptive statistics, correlation, regressio...

a sensor network is made up of a large number of sensors with limited energy. sensors collect environmental data then send them to the sink. energy efficiency and thereby increasing the lifetime of sensor networks is important. direct transfer of the data from each node to the central station will increase energy consumption. previous research has shown that the organization of nodes in cluster...
