However, the current trend in engineering is concerned with the active management of engineering resources, by cutting down expenses and ensuring the premises for further development. Advanced control strategies offer increased robustness, high reliability and efficiency, but they require fast computation times and powerful numerical resources. Hence, the trend in control engineering should be directed towards developing and employing reliable and energy-efficient devices that support the implementation of the advanced control strategies. This would eventually lead to a more sustainable use of the available technological resources and a decrease of the energy consumption. The present paper offers a comparison between two advanced control strategies for a DC motor, both implemented on a FPGA device. The experimental results show that both control solutions are viable, robust and use very little resources.","PeriodicalId":121216,"journal":{"name":"The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF)","volume":"7 40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124612044","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}

Unlike previous studies, we take into account both atmospheric turbulence and the pointing error effect. In order to model atmospheric turbulence, we employ a log-normal distribution for weak-to-moderate turbulent condition and a gamma-gamma distribution for strong turbulent condition. Meanwhile, we consider the pointing error effect by using a fading model where the influence of beam width, detector size and jitter variance is considered. More critically, we use a combination of these models to analyze the combined effect of atmospheric turbulence and pointing error to SC-QAM/FSO systems. Finally, we derive analytical expressions for evaluating the average symbol error rate (ASER) performance of such systems. Numerical results present the impact of pointing error on the performance of SC-QAM/FSO systems and how we use proper values of aperture size and beam width to improve the performance of such systems.","PeriodicalId":121216,"journal":{"name":"The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114364926","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}

In addition, future releases (Release-10 and beyond) of the fourth generation (4G) wireless networks are expected to carry an ever increasing number of broadband services. As such, the optimal configuration of 4G networks in the context of minimizing energy usage is very important. In this work we investigate the use of optimal power allocations in 4G networks in the context of co-operative communications. Our system models, which are based on emerging 4G standards, consist of multiple users communicating with a base station through the use of an additional relay station. We show, through analysis and simulations, how optimal power allocation schemes at the relay can lead to significant improvement in throughput. Such increases in throughput, in turn, lead to dramatic decreases in the energy usage of the network. We highlight two main energy savings that can be achieved without impacting any communication service; the opportunity to power-down base stations, and reduced energy consumption at the relay. We show how factor of two savings in energy usage can be expected from the deployment of our techniques.","PeriodicalId":121216,"journal":{"name":"The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124205297","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}

On one hand, we present a new joint shape-motion descriptor which we call as 3D Spherical Histogram of Oriented Normal Vectors (3DS-HONV), since it is a spatio-temporal extension of the original HONV quantized in a 3D spherical coordinate. We further prove that the Optical Flow fields in depth sequences could be used in conjunction with the presented descriptor to augment the ability of capturing in-plane movements; the experiments later show that this combination is more efficient than the standalone 3DS-HONV. In addition, a discriminative dictionary learning and feature representation via Sparse Coding is applied to proposed descriptors to relieve the intrinsic effects of noise and capture high-level patterns. By learning these sparse and distinctive representations, we demonstrate large improvements over the state-of-the-art on two challenging benchmarks, which results with an overall accuracy of 91.92% on the MSRAction3D and 93.31% on the MSRGesture3D datasets, respectively.","PeriodicalId":121216,"journal":{"name":"The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122976955","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}
