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}

More than 200 samples were created using various methods, concentrations and techniques, producing some consistent results and revealing some random properties. 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). Process and SEM stage images are provided, including dendrite blankets.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"42 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":"132224562","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}

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}

Hybrid novel design methodology is proposed to enhance the underfrequency load shedding in terms of consumer satisfaction level. A Consumer Priority Assignment Unit (CPAU) is proposed to be placed in each smart house. It gives the consumer the option to decide which loads to be shed. A reliable efficient self-pruning Ad-Hoc broadcast algorithm is proposed. The performance of the proposed algorithm is tested. The results indicate that the proposed algorithm nearly maintain the efficiency of the generic algorithm, at the same time it enforces higher reliability and prevents nodes (CPAUs) from taking wrong decisions.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"24 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":"129993520","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}

These monitoring systems are capable of large-scale monitoring, but they cannot immediately detect small-scale air quality changes. Wireless sensor networks are novel monitoring tools for small-scale monitoring. Through a wireless network, a large number of tiny sensor nodes can be deployed to a monitoring area. In this research, a reliable medium access control (MAC) protocol is presented for the urban air quality monitoring system based on the wireless sensor network. The proposed MAC protocol uses the concept of overhearing to reduce previously required control messages and data messages in the network. The reconfiguration and rejoining functions are also incorporated into the proposed MAC protocol for improving the stability of data transmission. Moreover, the proposed MAC protocol is designed for the sensor nodes built upon the TinyOS, aiming at air urban quality monitoring in Taipei, Taiwan. This urban monitoring system consists of 36 sensor nodes to detect carbon monoxide (CO) concentration, humidity, and temperature. The experimental data shows that the proposed MAC protocol is capable of stably working a long period of time, and it also indicates a significant difference in the pollutant concentration between the rush and non-rush hours.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"1 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":"129888289","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}

Message Passing Interface (MPI) and Multi-core techniques are converged to solve this problem. With performance enhancement, the power and energy consumption increase correspondingly. The Single-Chip Cloud Computer (SCC) is an experimental processor created by Intel Labs. This paper proposed an approach to study the power and energy consumption on the 48-core SCC many-core system and realized the message passing on the SCC. First, we profile the execution time, voltage and current on each running set. Later, we calculated the power and energy consumption, and compared them with increasing number of cores, varying voltage and frequency levels. Finally, we reached a conclusion focus on its scalability and relationship between power/energy consumption and system performance in terms of execution time.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"18 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":"126786846","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}
