The fixed point simulation results show that the proposed system has satisfied the minimum receiver sensitivity requirements that specified by the standards. Moreover, the proposed system has fitted for FPGA Virtex-5 XC5VTX240T implementation by utilizing 50 percent of total look up table (LUT) in the FPGA, and can reach the clock frequency up to 76.7MHz.","PeriodicalId":173600,"journal":{"name":"2014 International Conference of Advanced Informatics: Concept, Theory and Application (ICAICTA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122058461","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}

Since websites are generally placed as a public domain, there is a large chance of intruders to compromise the system at any time. C-panel raw access log data nowadays widely used by many security tools to analysis the user behaviors regarding to the activities on the web, however they commonly provide the descriptive analysis, rather than prescriptive analysis for prediction and estimation. In this paper, we introduce the solution about the website security protection mechanism by investigating the user behaviors using sequential rule-pattern analysis. Rule-patterns of user behaviors are created by mining the log data with sequential pattern analysis in near real time. Using anomaly-based intrusion detection and prevention system approach, our proposed system then can predict the user behaviors activities whether identified as baseline patterns or malicious patterns.","PeriodicalId":173600,"journal":{"name":"2014 International Conference of Advanced Informatics: Concept, Theory and Application (ICAICTA)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126798973","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}

One of the key issues for promotion of the policy is to use its proper assessment. At the present time, some assessment methods based on economic statistics or questionnaire investigations are proposed. However, the methods based on economic statistics can apply to only longterm assessment. On the other hand, the methods using questionnaire investigation include problems of consuming a lot of time and effort. In order to solve the problems, we develop a patent analysis method which uses geometric bias of patent applications, which is able to apply for middle/short-term assessment by using global Moran's test and local Moran's test that measures spatial auto-correlation. As a result, our method can detect the bias on patent applications.","PeriodicalId":173600,"journal":{"name":"2014 International Conference of Advanced Informatics: Concept, Theory and Application (ICAICTA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124233588","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}

To facilitate knowledge sharing in such a complex system is a challenging task. This paper proposes a conceptual model of a knowledge market as a possible mechanism to overcome the problem. By employing the market mechanism in higher education knowledge sharing, both seller and buyer of knowledge can meet and make transactions to exchange the results of intellectual efforts. When used is a digital environment, we use the term `Knowledge as a Service' to designate the support of the market actor and the term `Market as a Service' to refer the organization of the market. Supporting Optimum knowledge exchange is achieved as a consequence of the market mechanism. This framework is to be evaluated by a case study to support the design of a framework for knowledge exchange in the higher education system in Indonesia.","PeriodicalId":173600,"journal":{"name":"2014 International Conference of Advanced Informatics: Concept, Theory and Application (ICAICTA)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127585607","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}

Many approximation of strain hardening phenomena or cooling process have been carried out by experiments, but many cases are costly. There are alternative such as modeling and simulation. The purpose of this study is to predict the properties of material due to a particular strain hardening process for molybdenum and austenitic stainless steel. The optimization for some load to get stress and strain was analysed by genetic algorithm. The strain hardening mechanism behavior under stress and strain of material can be modeled using Neural Network with Backpropagation. Levenberg-Marquardt was selected to reach convergence rapidly. The true strain and stress of molybdenum converges to 0.997 and 60489.821 psi. For the austenitic steel are stabilizes to 0.809 and 158255.290 psi.

In this paper, we propose a method that exploits query reformulations provided by three major Web search engines (WSEs) as a means to uncover different query subtopics. In this regard, we estimate the importance of the subtopics by introducing multiple query-dependent and query-independent features, and rank the subtopics by balancing relevancy and novelty.

This study proposes a method for estimating inheritance relationship between contents when we assumed that contents have inherited from some other contents in its parts or properties. We estimate this relationship by targeting Niconico, a typical video-sharing Website in Japan, because we found this relationship from various meta-data given to the video. We think that we can observe the culture formation that occurs in social media by accounting for inheritance relationship of contents. We also think that we can analyze the phenomenon that a piece of contents inspired another one in chain in social media by applying the visualized culture formation. First, we propose a reference graph that represents inheritance relation obtained by analyzing the description of videos. We investigate characteristic of the relationship using edges in this graph. We confirm that some contents in Niconico has inheritance relationship with other contents. We have found that relationship is classified into the following four types: (1) Remake: Creator remakes some other videos into high-quality sound or high definition. (2) Arrangement: Creator arranges some other videos in their favorite style. (3) Partially-used: Creator uses some other videos in its music or scene as materials. (4) Inspired: Creator refers to some other videos in its representation or technique. We also propose a method for estimating this relationship using tags and titles from videos. We conducted experiments to evaluate our method and attained F-value 0.444 when threshold value is 0.330.","PeriodicalId":173600,"journal":{"name":"2014 International Conference of Advanced Informatics: Concept, Theory and Application (ICAICTA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128533224","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}
