One of the Fuzzy Logic application is to grade the agriculture produce based on its size. Currently, the grading is done based on observations and through experience. For further improvement, a high speed grading system using a Fuzzy Inference System is designed to grade the agriculture produce. In this research, a banana fruit was chosen to show the viability of this system. The Fuzzy Inference System grades a banana based on the extracted features that are obtained using Image Processing techniques of several images of each fruit. Since, this grading process requires a high speed processor, a typical computer platform is not a perfect choice. Therefore in this paper, we design and implement a grading system that uses a high speed digital signal processor. Hence, DSP TMS320C6713 was chosen for the implementation process. This paper discusses the implementation process of a fuzzy logic program on DSP TMS320C6713 platform.","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"26 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115717661","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}

Fast monitoring and early warning systems are very essential to prevent rapid malcodes spreading. The difficulty in detecting malcodes is that they evolve over time. Although signature-based tools such as network intrusion detection systems are widely used to protect critical systems, traditional signature-based malcode detectors fail to detect obfuscated and previously unseen malcode executables. Automatic signature generation techniques are needed to augment these tools due to the speed at which new vulnerabilities are discovered. In particular, we need automated techniques which generate signatures without mistakenly block legitimate traffic or increase false alarms. This work investigates a technique for automatically generating sound vulnerability signatures of novel rapid malcodes. In this paper, rapid malcode signatures are automatically generated based on their spreading behavior, specially aimed at automatically extracting and deploying signatures on the packet level, without the need for reassembly that could be used by signature-based firewalls network intrusion detection system. Evaluation on Universiti Teknologi Malaysia network corpus shows higher detection accuracy at 87% compare to 56% for Snort signatures. Moreover, false negative reduces to 14% compared to 78% for Snort signatures.","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128213962","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 occurrence of this fluctuation is due to the inconsistent input supply to the prime mover, mechanical failure and control system itself such as the process of quick operation of steam turbine governing, which would cause the pressure oscillation in turbine steam inlet pipeline. Consequences of this fluctuation may trigger situations such as power system low frequency oscillation and loss of synchronism, which can occur if the speed oscillation experienced by the machine exceeds its allowable limits. As a result, protection system will react, which causes the generator to be taken off line from the system.

Alternatively, Genetic Algorithms (GAs) and Particle Swarm Optimization (PSO) have been used efficiently in solving complex optimization problems, but they have a tendency to converge prematurely. In this study, the CSA is modified using the best solutions for each exposure (iteration) namely Remainder-CSA. The results show that the proposed algorithm is able to improve the conventional CSA in terms of accuracy and stability for single objective functions.","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130765225","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}
