Aspects allow programmers to implement crosscutting concerns in a modular and well-localized way. As a result, the well-known phenomena of code tangling and scattering are avoided. After a decade of research, AOP has gained acceptance within bot academia and industry. The current challenge is to incorporate aspect-oriented (AO) concepts into the software design phase. Since AOP is built on top of OOP, it seems natural to adapt UML to AO design. In this context the author introduces an extension to the UML metamodel to support aspect-oriented modelling.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"23 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121013248","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}

SBAC model considers this issue in its decision making process. However, time plays a crucial role in new computing environments which is not supported in the model. In this paper we introduce the Temporal Semantic Based Access Control model (TSBAC), as an extension of SBAC, which enhances the specification of user-defined authorization rules by constraining time interval and temporal expression over userspsila history of accesses. A formal semantics for temporal authorizations is provided and conflicting situations (due to the semantic relations of the SBAC model and a sub-interval relation between authorizations) are investigated and resolved in our proposed model. An architecture for the access control system based on the proposed model is presented, and finally, we discuss and evaluate TSBAC.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124485793","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}

Proved PC-based firmware was ported to new hardware platform for virtual instrumentation - National Instruments CompactRIO at the end of 2007. Platform change from PC to CompactRIO is not just code recompilation, but it brings up many needs for specific software redesigns. Paper describes how the monolithic executable for PC-based instruments was divided into three software layers to be ported on CompactRIO platform. The code for different parts of CompactRIO instrument is developed in a unified development environment no matter if the code is intended for FPGA, real-time processor of PC running Windows OS.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125448559","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}

As well, mobile robots also need a precise localization mechanism for the same reason. In this paper, we showed a combination of various localization mechanisms. Localization can be classified in three big categories: long distance localization with low accuracy, medium distance localization with medium accuracy, and short distance localization with high accuracy. In order to present localization methods, traditional map building technologies such as grid maps or topological maps can be used. We implemented mobile sensor vehicles and composed mobile sensor network with them. Each mobile sensor vehicles act as a mobile sensor node with the facilities such as autonomous driving, obstacle detection and avoidance, map building, communication via wireless network, image processing and extensibility of multiple heterogeneous sensors. For localization, each mobile sensor vehicle has abilities of the location awareness by mobility trajectory based localization, RSSI based localization and computer vision based localization. With this set of mobile sensor network, we have the possibility to demonstrate various localization mechanisms and their effectiveness. In this paper, the preliminary result of sensor mobility trail based localization and RSSI based localization will be presented.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129392258","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}

Similarity clusters have been defined on the basis of a general concept of similarity measure. The method is based also on the properties of morphological spectra as a tool for image presentation. In the proposed method similarity of selected spectral components in selected basic windows are used to similarity of images evaluation. Similarity clusters are detected in an iterative process in which non-perspective subsets of images are step-by-step removed from considerations. In the method similarity graphs and hyper-graphs also play an auxiliary role. The method is illustrated by an example of a collection of medical images in which similarity clusters have been detected.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131184571","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}

In distributed computing, it is possible that tasks fail, and it is difficult to get accurate information about hosts and tasks. WQR (workqueue with replication), which was proposed by Cirne et al., is a good algorithm because it achieves a short job-completion time without requiring any information about hosts and tasks. However, in order to use WQR for distributed computing, we need to resolve some issues on task failure detection and task cancellation. For this purpose, we examine two approaches-the conventional task timeout method and the soft state method. Simulation results showed that the soft state method is more robust than the task timeout method.","PeriodicalId":267715,"journal":{"name":"2008 International Multiconference on Computer Science and Information Technology","volume":"23 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132938128","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}
