Body sensor networks (BSNs) are an emerging class of cyber-physical systems (CPS) which present interesting challenges. One significant challenge is that unlike other CPS where the physical process of interest is engineered (automobiles, chemical processes, buildings, etc.), the physical process here, the human body, is not engineered and hence is more difficult to understand and model. BSNs are used...
Atrial fibrillation (AF) and other structural heart diseases cause structural remodeling in the atria. Structural remodeling leads to local heterogeneities of conduction between muscle bundles as well as between the epicardium and endocardial bundle network which enhances endo-epicardial electrical activation time differences and breakthroughs. In order to investigate the mutual influence between...
The paper concerns the possibility of using temporal logics for knowledge management. The idea of knowledge management is presented, along with the most typical computer solutions for this area. The temporal aspect of knowledge management is pointed out. Having in mind this temporal aspect, the paper presents possible advantages of extending knowledge representation for knowledge management with temporal...
This paper presents the general structure and implementation features of the original complex software for command and control of the anthropomorphic gripper for robots. The software has three modules: RoboVISION, RoboSIM and RoboCOMMANDER. RoboVISION is a software module for tracing, visualization, shape recognition, measurement, and efficiency evaluation for 3D model generation of objects to grip...
Steve Jobs' world-changing innovations at Apple are usually considered to be his marriage of art and technology. Here, the author argues that the major changes in our world resulted from clever business models, especially those that created ecosystems in which other parties could participate. Moreover, we have Jobs to thank for a major world-changing technology: Wi-Fi.
Physiological signals, medical images, and biosystems can be used to access the health of a subject and they can support clinicians by improving the diagnosis for treatment purposes. Computer-aided diagnosis (CAD) in healthcare applications can help in automated decision making, visualization and extraction of hidden complex features to aid in the clinical diagnosis. These CAD systems focus on improving...
Distributed computing has many opportunities for Modeling and Simulation (M&S). Grid computing approaches have been developed that can use multiple computers to reduce the processing time of an application. In terms of M&S this means simulations can be run very quickly by distributing individual runs over locally or remotely available computing resources. Distributed simulation techniques...
This paper addresses HCI and visualization, and its social aspects. It reports the findings from a survey using 3D animation to illustrate proposed developments within the fragile ecologies of Langkawi. 3D animation has been regarded as an interface in this paper because its key purpose is to facilitate communication. Tourists became the target users who provided feedbacks about the schemes' environmental-fit...
The molecular dynamics of hemorphin-4 peptide, corresponding to the sequence of the physiologically active center Tyr-Pro-Trp-Thr of hemorphins, was investigated. Simulations were carried out for stabile conformational states of this tetrapeptide in 7 ns time interval using computer modeling proqram. On the base obtained results the aminoacids side chains flexibility were analysed.
The codification system of models has been suggested in the article, which unlike the others makes it possible to unify the description of the basic information models. The use of the proposed logical-mathematical apparatus of representation models was illustrated by way of example of developing an automated system for building computer control systems of management reporting. The formation of the...
Building information technology includes production process information technology and management information technology. The first one can improve efficiency and productivity, and the other one can improve the business treatment efficiency and management level. In this paper, combining with the application requirement of building construction, application research o virtual simulation technology...
In this paper we're dealing with the problem of detecting malware using behaviour model. For better malware description we have divided this model into two parts — malware spreading model and malware statistical behavioural model. Spreading models are typical epidemiological models like SI model, advanced SIR and SEIR models and empiric file spreading model. In statistical behavioural model we're...
Passenger stations are usually having complex structure, and filled with crowds and luggage. Once an emergency occurred, the passengers were perhaps required to evacuate immediately, hence they may drop off their luggage arbitrarily because of scare, tension and some other factors, where the abandoned luggage inevitably result in additional obstacle for evacuation. This article improves the traditional...
This study was conducted to explore the effects of computer-based modeling learning activates on sixth graders' modeling practices. The subjects of this study were 33 sixth graders in Taipei Taiwan. The experimental group received an instruction which was based on Model-It, a computer-based modeling tool, and a set of computer-based modeling learning activities. Paper and pencil tests of modeling...
The purpose of the study was to investigate digital divide issue among urban and rural k-12 schools in Chinese economically developed regions. The researchers selected three representative primary schools (one from urban area, one from rural area and one is located in urban area but all of its students are from rural area) to explore the issue. The study is quantitative by nature and random sampling...
This paper compares two different approaches, followed by our research group, to efficiently run NEPs on parallel platforms, as general and transparent as possible. The vague results of jNEP (our multithreaded Java simulator for multicore desktop computers) suggests the use of massively parallel platforms (clusters of computers). The good results obtained show the scalability and viability of this...
This meta-analysis employs a theoretical framework in quantitatively synthesizing empirical studies that investigate the effects of game-based learning versus classroom instruction on the student learning effect. Analyses of 14 journal papers with 21 studies on 946 students were conducted according to how media were used to support game-based learning. The results indicate that the effect sizes for...
In computer's word, the basic idea of DNA computing is using processing power of organic molecular information instead of digital switch components. In recent years, DNA computing has become one of (he important researches which solve complex problems. In this paper, in comparison with the analysis of the development of DNA computing, we introduce the working principle and mathematical model, and...
The traditional virtual biological behavior animation is realized by the key frame technology, but there are some deficiencies. Therefore, we propose the modeling of fish roe Based on artificial life method to animation fish roe using artificial life method and virtual reality technologies. It can animated the fish roe division without any of the key frames, not only has the basic characteristics...
This study evaluates the current state of electronic commerce (EC) research in China. The authors examine 275 articles in 18 journals acknowledged as the top journals of the field from 1998 to 2010. This study summaries some literatures and classification for EC. The authors present the four classifications which are research field, research objects, operational progresses and research methods. The...
