The optimal signal constellation is not equally spaced. We show that the optimal system has a lower error probability than a conventional system, i.e., a system with source coding, equiprobable symbols, and equal space constellation. In several cases presented in this paper the error probability of the optimal system is significantly lower than in the conventional system. We prove that even with equal symbol probabilities the equal space constellation is not optimal for 16QAM, but only asymptotically optimal. Finally, we evaluate the robustness of constellations to estimation error in symbol probabilities.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131100889","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}

SEM images were taken of many samples, showing various stages of growth and the results of the various techniques used to grow the SiNWs. These images and experiments show that previous notions on the growth of SiNWs may be misunderstood. The experiments performed and the images taken show that SiNWs growth process is highly randomized, starting at the beginning of the etch with no SiNWs, and ending with SiNWs branching away from a centralized agglomeration made up of corrugated, ribbonized Silicon (Si).

Video repositories are growing at an astounding rate due advances in multimedia technologies. The vast size of video repositories presents challenges for users attempting to identify preferred content. Automated methods for content discovery are necessary to meet the needs of users. One of the more challenging areas of video content discovery is in identifying affective, or emotional, video content. Automatic affective video indexing techniques attempt to use computer-based methods to automatically identify content in videos that is affective in nature. This is the first known automatic affective video indexing study that focuses on slapstick, one of the most popular types of humor techniques. The study shows positive results and contributes to the field by identifying the targeted affective content without relying on actual human emotional responses.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134195889","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}

Through the use of these models, this paper will identify enhanced alternatives that can replace less secure traditional methods of logging-on to computers.

Optimal planning of distribution system with distributed generation resources is not only concerned with the sizing of distributed generators but gives due weightage to the placement of generators as well. The installation of DG at optimum location boosts the performance of distribution system as well as presents a cost effective solution thus giving a new dimension to distribution system planning. The positive impacts of optimal distributed generator placement are reflected in terms of improved distribution system reliability, reduced customer interruption costs, reduction in losses and improvement in voltage profile as well as power quality at the consumer terminal. In order to enable electric utilities to obtain maximum benefits, the placement problem calls for state of art optimization techniques capable of handling multiple objective simultaneously in order to present the best feasible solution. This paper aims at providing an overview of several methodologies which have been adopted for finding out optimal location of distributed Generator in distribution system in order to maximize benefits.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132442191","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}

Tuning these metrics during embedded system designs will definitely impact the cost and performance of Smart Grid devices and systems. In this research, we are aiming to achieve secure and high performance network communication platform based on various implementation of the TCP/IP protocol stack. Firstly, we deployed NicheStack TCP/IP for an embedded Web server application. Then, we integrated the ECC (Elliptic Curve Cryptography) C code within the web server source code to achieve a secure communication. Consequently, we showed that the integrated system: the web server, and the ECC program hides information if the secret is not provided. We used an http client to access the web server through the Internet. The client sends an encrypted data securely through the network to the embedded web server application. Secondly, we are in a stage to design a complete open TCP/IP hard core on an FPGA. Preliminary simulation result via ModelSim confirms proper operation of decode instruction module at the hardware level. All Modules will be synchronized to the same clock and reset signals.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"84 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132934227","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}

SHM techniques have been employed to reduce maintenance and repair costs while maintaining safety and reliability of aircrafts. In this paper we have investigated the benefits provided by integrating decision fusion algorithms to SHM systems. The decisions made by classifiers acting on sensory data are combined using decision fusion algorithms to arrive at unified final decisions regarding the status of the monitored structure. First, synthetic decisions were generated and used for testing and performance evaluation of the different decision fusion algorithms. Second, several different decision fusion algorithms were developed and tested on the synthetic decisions. The Dempster-Shafer theory of evidence, fuzzy logic type-1, and fuzzy logic-type2 were used for development of the decision-fusion algorithms. Finally, the fusion algorithms were tested on decisions extracted from experimental data to validate their performances. The testing and evaluation results showed significant improvement due to fusion process integrated at the end of the feature classification process. The development of the fusion algorithms, their testing results on the synthetic decisions and decisions extracted from real experiment are reported in this paper. Also, performance analysis of decision fusion algorithms is provided in the paper.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133118821","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}
