Protein solubility plays a major role and has strong implication in the proteomics. Predicting the propensity of a protein to be soluble or to form inclusion body is a fundamental and not fairly resolved problem. In order to predict the protein solubility, almost 10,000 protein sequences were downloaded from NCBI. Then the sequences were eliminated for the high homologous similarity by CD-HIT. Thus,...
In this paper, some new measurements based on Chi square test are presented. Protein sequences are characterized by the frequency of occurrence of the 20 amino acids. Each frequency of a protein sequence is deemed as a sample for various populations. The value of Chi square in the Chi square test is used to measure the dissimilarity of each pair of the protein sequence. Furthermore, some transformations...
Pipe network is a complex spatial distribution system. In order to define the internal structure of the pipe more, this article aims to analyze the section spatial topological structure of the pipe network from a 2-dimensional GIS pipe network map by using a generation algorithm of transverse section drawings and vertical section drawings. Based on C# and ArcEngine, this algorithm visualizes transverse...
Introducing grid service into the Geological Spatial Information System (GSIS) can integrate the heterogeneous geological resources, and pack a variety of spatial geological resources into spatial grid service, which can shield the heterogeneity of all kinds of spatial geological resources. It can provide shared interface with this unified software entity of spatial grid information service to integrate...
An ad hoc network is interference limited, the power control strategy plays an important role in the study of transmission capacity. In this paper, a well-known power control strategy, i.e., channel inversion, is studied. By comparing with no power control case, we found that using channel inversion increases the level of normalized interference in network, which makes the performance of network worse.
Probability of packet success of ad hoc networks is determined by two factors, one is the probability of successful transmission at the receiver, and the other is the probability of successful detection at the detector. In this paper, we study the probability of successful transmission by using the Poisson model with SIR based power control. Taking direct sequence scheme with binary phase shift keying...
To understand the functions of various proteins, it would be helpful to obtain information about their subcellular locations. With the rapid accumulation of newly found protein sequence data in databanks, it would be worthwhile to develop a fast computational prediction method to identify protein's subcellular location. In this paper, we considered 4 subcellular locations of proteins from rice: chloroplast,...
This paper described the way of generating a reasonable bus scheduling, so that getting the lowest operating costs, the shortest waiting time for average passenger and the smallest vehicle demand in some bus lines of regional area. To achieve information resource and transport ability sharing, the transit regional scheduling optimization model is set up, and solved by hybrid simulated annealing/genetic...
