An accurate estimation of channel can greatly increase the throughput of the whole systems. Training-based methods are commonly used to learn the channel response. But the traditional channel estimation doesn't take the characteristics of wireless channel into account. On the other hand, Compressive sensing has recently gained much attention in various areas. In communication, compressive sensing is also been used to estimate the channel response in wireless orthogonal frequency division multiplexing (OFDM) systems. In this paper, we consider the channel estimation of frequency selective wireless channels which is the opposite of time selective wireless. An optimization for channel estimation based on compressed channel sensing is proposed in this paper. The optimization considers the character of channel. We use the delay of the channel to optimize the algorithm of Orthogonal Matching Pursuit. We present the LS and CS estimators and a method for modifications compromising of performance. The bit error number and the normalized mean square error for a 16-QAM system are presented by means of simulation results. Our simulation results demonstrate a significant reduction of the performance of the bite error number and the normalized mean square error. So that, the optimization for channel estimation based on compressed channel sensing achieves the same bit error number with the reduction of pilots by comparing the traditional channel estimation, then, the modified method also increase spectral efficiency.","PeriodicalId":387936,"journal":{"name":"2012 13th ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127659061","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 objective of this paper are (1) to introduce real option theory and to discuss its applicability as a decision support tools, (2) to exemplify some real options present in 4G LTE communication of MNO markets, and (3) to apply real option approach based on the proposed pricing model to the selected case to demonstrate the power of option pricing models as a decision support tool in 4G LTE mobile network. The application of real option approach is valuation of investment opportunities when the future capacity prices are uncertain but the investment costs are unknown. The optimal pricing of capacity tariffs is identified under stochastic capacity prices. The case demonstrates how real option models can be used to derive decision rules to problems faced by several telecom parties.","PeriodicalId":387936,"journal":{"name":"2012 13th ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785101","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 aim is to use the BN model to identify defective software modules for efficient software test in order to improve the quality of a software system. It can also be used as a decision tool to assist software developers to determine defect priority levels for each phase of a software development project. The BN tool can provide a cause-effect relationship between the software defects found in each phase and other factors affecting software defect detection in software testing. First, we build a State and Transition Model that is used to provide a simple framework for integrating knowledge about software defect detection and various factors. Second, we convert the State and Transition Model into a Bayesian Network model. Third, the probabilities for the BN model are determined through the knowledge of software experts and previous software development projects or phases. Last, we observe the interactions among the variables and allow for prediction of effects of external manipulation. We believe that both STM and BN models can be used as very practical tools for predicting software defects and reliability in varying software development lifecycles.","PeriodicalId":387936,"journal":{"name":"2012 13th ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115568435","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 also means that the applications may be running as long as IMS provides standardized and extended interfaces. The mentioned applications have been selected as representative for process-oriented business organizations characterized by service- and process-oriented models and implementation (SOA, Web Services, Semantic Web, Web of data, content- and context aware applications, etc.) based on service-oriented architectures, pervasive computing and communication-enabled applications paradigms. In the applications' architectures complex, \"autonomic\" self-organizing distributed systems/workflows with autonomous components are specified, realized, simulated and evaluated as a based on active component technologies. Application-driven content- and context-aware networks support process- and service-oriented processes. A combination of the above mentioned models (the push and pull model), architecture and approaches are possible and attractive from research, application and business perspectives.

Many computers are installed a database system and users maybe want to use these database systems as one system. The multi-database system is one of the solutions to this request. The multi-database system is a kind of the distributed database system. It is a cluster of independent database systems. As the distributed database system, the multi-database system has some problems. One of these problems is data migration among individual database systems in the multi-database system. Many reorganization techniques for distributed database systems already proposed. But these techniques are not always adaptive to the data migration in the multidatabase system. In order to overcome this problem, we adapt the incremental scheme to the data migration in the multidatabase system. In our new scheme, a large data migration operation is divided into small ones, and other operations are inserted between them. The experimental result proves the improvement of the turn-around times of other operations.","PeriodicalId":387936,"journal":{"name":"2012 13th ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114519749","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}

SPH is a type of particle method and easy to control computational time by reducing or increasing the number of particles, however, it is difficult to change the number of particles while maintaining the same volume of fluid and the stability during a simulation. In this paper, we propose a new method to automatically adjust the number of particles, mass, radius in kernel functions and gains of density feedback for a real-time process while maintaining the stability. This paper also proposes to apply the method to a system using parallel processing with multi-thread programming. Finally, simulations are performed to estimate the effectiveness of the proposed method for parallel processing.","PeriodicalId":387936,"journal":{"name":"2012 13th ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128400178","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}
