Considering the importance of the solution to some problems of wireless sensor networks such as redundant low-rate data, balance energy and low reliability of the communication channel, an adaptive algorithm is proposed in this paper. It is formulated for dynamic hybrid routing which seamlessly combines plane routing and hierarchical routing. The data query packet of Sink node is divided into single-point...
The Modular-2DPCA is an improvement and promotion of 2DPCA. Modular-2DPCA method creates the covariance matrix by blocked sub image, which make better robustness. There are many parts in a human face, with each part could own different weight in face recognition, block made the research of parts became possible. This paper directs the characteristic of block, calculating the mean value and covariance...
This paper describes design and implementation of a series of kernel experiments for operating system course teaching. The experiment series consists of ten projects which comprise five parts: booting, interrupt and exception handling, process schedule, memory management, and signal processing. The final project itself implements an entire monolithic Unix-like operating system kernel compatible with...
Objective: to understand the current state of nursing students' subjectivity-oriented education and explore the teaching policies to develop it. Method: using random sampling, a self-designed questionnaire is administered among the nursing students who attended university in the year between 2005 to 2008. Result: most of the nursing students lack subjectivity in their study. Senior students' subjectivity...
Electronic examination paper (EEP) should be protected in copyright and tamper-resistant in its lifetime. A security solution based on watermark for this problem is given in this paper. Two kinds of watermark are designed: copyright watermark and tamper-resistant watermark. Copyright watermark is an ID of the examination, which is consists of proposition, time of exam, exam taker, object of examination,...
In particle Alter algorithm, the resampling step effectively solves the problem of particles degeneracy; however, it reduces the particle variety. This article describes how to use chaos, immunity algorithm and genetic algorithm carried on particle resampling corrective method. We present a novel algorithm which combines immune algorithm, chaos and genetic algorithm. This immune genetic algorithm...
Cancer is one of the most the gravest problems facing mankind. In 2008, it is estimated that over 7.6 million lives have been claimed by cancer. Early and precise detection plays a key role in treating the disease and improve survivability of patient. Among data classification algorithms, discrete particle swarm optimization (DPSO), a technique based on standard PSO has proved to be competitive in...
In this paper, we present a method for localizing the global position of the heart from Cine MRI images. This method is fast, and fully automatic. It depends on the standard deviation from the stack of images that we work on, and the position of the heart will have the greatest motion standard deviation because the heart is almost the only organ moves in the images. We test this method on 14 patients,...
Objective: To identify the thin layer of quercetin in Berchemia lineata and set up its content determination method. Methodology: To identify the quercetin in Berchemia lineate by adopting TLC (thin-layer chromatography); and to determine the content by HPLC (high performance liquid chromatography). The chromatographic column is Diamonsil ODS Cm (4.6 mm × 250 mm, 5 µ m) and the mobile phase is acetonitrile...
In this paper, we aim to discover interesting medical association rules from medical datasets for prediction purposes. This medical dataset is a data set of patients' records, where each record is a combination of both textual information (personal and medical) and extracted image features for the given patient. We provide an association rule mining system that discovers constrained association rules...
Objective: To develop a monoclonal antibodies against Rabies virus phosphoprotein (P), which has conserved domains, and such regions are potentially interesting targets for the diagnosis. Methodes: In the study, a rabies virus p gene coding for the rabies virus phosphoprotein was amplified by PCR and cloned into the expression vector pET32a (+). The recombinant protein was expressed in Escherichia...
This paper introduces how to apply plan recognition technology to Intelligent Tutoring System (ITS). ITS can recognize the student's learning plan automatically, guide students to chooses teaching content and strategies according to the recognized plan. While much effort has been devoted to ITS, it can be shown the assumptions underlying that many current plan recognition approaches do not hold in...
In recent years, there were a lot of malignant event reports about the university student against the law. Therefore, moral education is of most importance. Moral education courses should be combined with the life. Moral education through the computer network technology can improve the teaching effect. This relies on the construction quality of the computer aided teaching system.
PSO algorithm with stochastic inertia weight has better converging speed and ability than the basic PSO algorithm. The PSO algorithm with stochastic inertia is analyzed, and is applied to the clustering algorithm. The data sets of UCI data collection are used to experiment, the results of the experiment shows that the new clustering algorithm is better than K-means algorithm in quantization error,...
Objective: Simple randomization, stratified block randomization and minimization are three most commonly used allocation methods in clinical trials. Our objective was to make a comparison of their balance ability from the true data of a clinical trial with a serials observational point from 50 to 1350 patients in 552 combined strata. Study design: We created random sequences by SAS plan program, and...
Emodin and quinalizarin were obtained by separation and purification with silica gel column chromatography and preparative high performance liquid chromatography from Aspergillus.ochraceus. The best condition of preparative high performance liquid chromatography was mobile phase, methanol: water (60: 40, V/V); the flow rate, 60 mL/min; sample mass in injection volume, 0.6g (10mL); the detective wavelength,...
