The main concern for a bank's manager is to take good decisions in order to minimize the risks level associated to bank's activities. It is very important for a bank to have knowledge of causes which generate the financial crises or imbalances. Lending is one of the most risky activities in banking area and adequate methods to support the decision making process are necessary. In this paper the authors present a prototype decision support system based on data mining techniques used in lending process. The proposed system was designed to assist a customer who applies for a credit and it may represent an extension for e-banking activities.","PeriodicalId":277269,"journal":{"name":"2011 RoEduNet International Conference 10th Edition: Networking in Education and Research","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116122150","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}

E-learning makes learning content available even in remote locations, eliminating the need to travel to the place where the content is delivered. Nevertheless, the current E-learning platforms have some limitations like in scalability, availability, distribution of computing power and storage capabilities. The main aim of this following paper is to present a way for the integration of GRID technologies into new learning methodologies, in the same time answering the following questions: How will this improve the quality of traditional E-learning platforms, how can this be realised and what other benefits will there be for the universities, the students and for the work field as well.","PeriodicalId":277269,"journal":{"name":"2011 RoEduNet International Conference 10th Edition: Networking in Education and Research","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114537769","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}

Cognitive Radio Technology which is an opportunistic network and is equipped with fully programmable wireless devices that empowers the network by OODA cycle and then make intelligent decisions by adapting their MAC and physical layer characteristics such as waveform, has appeared to be the only solution for current low spectrum availability and under utilization problem. In this paper a novel Dynamic De-Centralized Hybrid “DDH-MAC” protocol for Cognitive Radio Networks has been presented which lies between Global Common Control Channel (GCCC) and non-GCCC categories of cognitive radio MAC protocols. DDH-MAC is equipped with the best features of GCCC MAC protocols but also overcomes the saturation and security issues in GCCC. To the best of authors' knowledge, DDH-MAC is the first protocol which is hybrid between GCCC and non-GCCC family of protocols. DDH-MAC provides multiple levels of security and partially use GCCC to transmit beacon which sets and announces local control channel for exchange of free channel list (FCL) sensed by the co-operatively communicating cognitive radio nodes, subsequently providing secure transactions among participating nodes over the decided local control channel. This paper describes the framework of the DDH-MAC protocol in addition to its pseudo code for implementation; it is shown that the pre-transmission time for DDH-MAC is on average 20% better while compared to other cognitive radio MAC protocols.","PeriodicalId":277269,"journal":{"name":"2011 RoEduNet International Conference 10th Edition: Networking in Education and Research","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123663643","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}

Modern erasure correcting codes promise to offer a very simple and efficient solution to data transfers over these channels, opening up also other interesting applications. Amongst them one can enumerate reliable large scale content distribution, high quality real-time data transfers, distributed storage and others. These considerations make the study of such codes an actual and interesting topic. This paper presents a performance evaluation of some rateless erasure correcting codes. The performance evaluation is based on simulations, having as a secondary purpose the study of the feasibility of some proposed applications found in current literature. Several scenarios including various loss models have been simulated and the results show that these codes may indeed find applications in large-scale content distribution.","PeriodicalId":277269,"journal":{"name":"2011 RoEduNet International Conference 10th Edition: Networking in Education and Research","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134263774","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}

The main goal of the new generator design is to take advantage of the fast randomness generation and different statistical quality of multiple PRNG families and provide an unpredictable combination method, which improves the quality of produced randomness and mitigates certain security problems the individual generators are exposed to if used on their own. Furthermore, the proposed generator leverages the processing power of multi-core and SMP systems by enabling the parallel execution of multiple generators selected by the user's unpredictable mouse movements. The result is a stream of unpredictably combined pseudorandom number sequences which shows high randomness quality - evaluated by the well known NIST statistical test suite, improved by the unpredictability and nondeterminism characteristic to human-computer interaction and doubled by a high generation speed provided by the parallel generation strategy. These characteristics enable the generator to be considered suitable for producing high quality randomness with the promise of cryptographic security.","PeriodicalId":277269,"journal":{"name":"2011 RoEduNet International Conference 10th Edition: Networking in Education and Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130574468","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}
