Transmission limitations motivates the use of a hierarchal routing mechanism that enables each soldier to communicate with distant soldiers using intermediate powerful nodes that hover within the transmission radius. Our research combines various types of transmitters, including short-range personal transmitters, vehicle-mounted transmitters, helicopters and a geostationary earth-orbit (GEO) satellite. Each of these entities possesses a different communication range, velocity, and altitude. We consider the various tradeoffs rising from such a heterogeneous theater, and compare two ad-hoc protocols - AODV, which is based on dynamic updates of local cached routing tables, and MRA, which is based on dynamic updates of virtual coordinates. Our results show that for the MRA algorithm one \"flat\" network is sufficient, and there is no need to use clustering methods. We further show that the GEO satellite constitutes a ubiquitous mediator that contributes to the connectivity and stability of the network.","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127265300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Up to now, the need for it was met by human knowledge that a domain expert or a system supervisor have contributed to a given application task. The advent of the Internet has drastically changed this state of affairs. Internet sources of visual information are diffused and dispersed over the whole Web, so the duty of information content evaluation must be relegated now to an image content understanding machine or a computer-based program capable to perform image content evaluation at a distant image location. Development of Content Based Image Retrieval (CBIR) technologies is a natural move in the right direction. However... In this paper the author will argue that the basic assumptions underpinning the majority of CBIR designs are wrong and inappropriate, (like many other basic conceptions that computer vision community proudly holds at this time).","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128599920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was used also in the academic year 2001-2002 and was very successful in improving understanding and achievements of the students. The paper describes the system features and the case study of its implementation. Lessons drawn from use of the CAPA system are discussed. The system no doubt contributed significantly to increased understanding and higher achievements in the final exams. This was at a price that students felt that they had to devote more time to study than traditionally required. The instructor has to invest more time than traditionally done in composing new problems and managing the system. However, the increased interaction with the students makes the teaching process much more interesting and rewarding.","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128912415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A KBS course is often not included in IS education curriculum, and when it is included it is usually an elective course taken by only a few students. We describe the content, the instructional strategies and an accompanying study. Besides providing students with new tools to extend information systems capabilities, this course provides an opportunity to discuss, explore and experience issues of knowledge representation, modeling, abstraction, knowledge management and programming paradigms. This is accomplished through learning activities that involve metadata creation by students for code examples that are used throughout the course. These iterative activities are done both individually and collaboratively in teams. The paper presents some findings and discusses their implications for IS education.","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"32 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129132964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intravascular MRI (IVMRI) is the first implementation of the technology and is designed for use in coronary catheterization procedures. IVMRI exploits the unique magnetic field characteristics inherent in the self contained, miniature magnet and coil configuration, to provide contrast enhancement for measuring the molecular self- diffusion of water molecules in biological tissue. The rate of the self-diffusion of water molecules in biological tissue provides accurate information as to the molecular environment that the water molecules experience. In the case of atherosclerotic plaque which is comprised of two major groups namely fibrotic and lipid tissues, the self-diffusion of the water molecules provides a measure of the relative concentrations of the two groups present within the field of view of the IVMRI probe. The unique plaque classification method along with conventional MR capabilities and the miniature size of the probe have made the technology an ideal candidate for coronary wall imaging. The current generation contains an IVMRI probe at the end of a custom delivery system (8F guiding catheter and 0.014\" guide wire compatible) and is designed for use in standard catheterization laboratories. In addition, the application of the technology for prostate imaging and cancer detection is currently being evaluated.","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134396321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding high quality information is hard. This partially stems from prevalent use of search engines (SEs) for information seeking tasks, when, for appropriate tasks, wise use of relevant digital libraries (DLs) could provide high quality information. However, the awareness and discovery of DLs on the Web is still lacking. The solution proposed herein is of the SELFDL (SE locator for DLs) model that is patterned after the popular Google style. Its task is to locate DLs, organize them in various knowledge structures, and provide a usable interface for locating relevant DLs. We describe the SELFDL framework that has three major components: directory, index and meta-search engine that are based on a common infrastructure. SELFDL's aim is to tilt the current balance of use between SEs and DLs in the direction of increased use of DLs, when that use is merited, hence increasing the qualitative use of the Web.","PeriodicalId":194063,"journal":{"name":"2006 International Conference on Information Technology: Research and Education","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122076160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
