We have built a parser system to read Arabic newspaper articles, isolate the tokens from them, find the part of speech, and the features for each token. To achieve this goal we designed a set of algorithms, we generated several sets of rules, and we developed a set of techniques, and a set of components to carry out these techniques. As each sentence is processed, new words and features are added to the lexicon, so that it grows continuously as the system runs. To test the system we have used 75 articles (7 108 words) from the ASSAHAFA newspaper. The system consists of several modules: the tokenizer module to isolate the tokens, the type finder system to find the part of speech of each token, the proper noun phrase parser module to mark the proper nouns and to discover some information about them and the feature finder module to find the features of the words.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116989101","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}

Nowadays it is obvious that the whole range of services is widely in use, and in addition performance is degrading due to the rapidly increased number of mobile subscribers, numbering over 2.9 billion subscribers in the world today. The performance of cellular networks is the most important issue concerning their operators. The main goal is to keep subscribers satisfied with the delivered quality of service. In order to achieve the best performance, service providers have to monitor and optimize their network continuously. A Network Management System (NMS) with an online database is responsible for the collection of data on the networks. For greater effectiveness, operators install systems that do a lot more than collect and store raw data. These systems are easier to use and take advantage of all the data provided by NMS. In this paper we summarize measurements that were carried out to evaluate the performance of the GSM's Air-Interface (Um). We developed a new global Quality of Service (QoS) indicator that would be provided to business development department on a monthly basis. It would represent the overall impact of the quality of service on customers. For these measurements, an operative GSM-1900 network was utilized. The parameters selected (performance metrics) on a daily basis for measurements were those with a direct impact on subscribers.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124856622","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}

This method provide features in 12 directions against 3 and 6 directions in DWT and CWT respectively. Iris features are obtained by computing energies and standard deviation of detailed coefficient subbands in 12 directions per stage, at 3 level of decomposition. Canbera distance is used for matching. The results are obtained using DWT, CWT combination of CWT and RCWF on UBIRIS database of 24000 image. The performance measure, ZeroFAR, is reduced from 6.3 using DWT to 2.6 using proposed method. The results are also comparable with the Daughman method. The method is also computationally efficient as compared to Gabor Filters.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125049349","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 this paper, we propose an efficient scheme to support efficient range query processing over structured P2P systems, while balancing the storage load. The paper proposes a rotating token approach to balance the storage load by placing joining nodes in appropriate locations in the identifier space to share loads with already overloaded nodes. Then, to support range queries, we utilize an order preserving mapping function to map keys to nodes in order preserving way without hashing. In this study, we carry simulation experiments with synthetic data to measure the performance of the proposed approach.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126196104","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}

This paper presents a novel steganography methodology that pursues text summarization in order to hide messages. The proposed summarization-based steganography (Sumstega) methodology takes advantage of recent advances in automatic summarization techniques to generate a text-cover. Sumstega does not exploit noise (errors) to embed a message nor produce a detectable noise. Instead, it pursues the variations among the outputs of autosummarization techniques to conceal data. Basically, Sumstega manipulates the parameters of automatic summarization tools, e.g. how the word frequency weights in the sentence selection, and employs other contemporary techniques such as paraphrasing, reordering, etc., to generate summary-cover that looks legitimate. The popular use of text summaries in business, science, education, news, etc., renders summary an attractive steganographic carrier and averts an adversary's suspicion. The validation results demonstrate the effectiveness of Sumstega.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126803314","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 these systems, the base station broadcasts TV channels in bursts with bit rates much higher than the encoding rates of the video streams. Thus, mobile devices can receive a burst of traffic and then turn off their radio frequency circuits till the next burst in order to save energy. To achieve this energy saving, the base station must carefully construct the burst schedule for all TV channels. In this paper, we formulate the problem of determining the optimal burst schedules for broadcasting multiple TV channels. We show that this problem is NP-complete for channels with arbitrary bit rates. We then propose a practical simplification of the general problem, which allows TV channels to have different bit rates, but at power of two increments. Using this simplification, we propose and analyze an optimal burst scheduling algorithm. We implement our algorithm in a mobile TV testbed and we present empirical results to demonstrate its efficiency and optimality.","PeriodicalId":412180,"journal":{"name":"2008 International Conference on Innovations in Information Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114416180","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}

This paper introduces the use of policies in processing and disseminating contextual information to provide context aware mobile services. The policy-based approach facilitates end-users services context awareness by dynamically creating new context policies and by triggering actions of predefined policies in response to satisfied context sensitive conditions. The enforcement of policies on services automatically results in the adaptation of their behavior according to context changes.
