The optimal parameterization of SO(3) is determined so that robotics attitude system can become more effective. Given a robot's local translational velocity and local angular velocity, numerical integrations along a robot's trajectory using rotation formalisms are performed. Comparing the resulting trajectory with a robot's true trajectory, this paper considers numerical error, integration time and steps as parameterization methods' evaluation criteria.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116653617","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 proposed PSO have been applied for the ORPD problem with different objectives such as minimization of active power losses and improving the voltage profile satisfying various constraints of power flow equation, generator voltage limits, switchable capacitor banks, transformer tap changer limits, and transmission line limits. The proposed method has been examined and tested on the IEEE 30-bus and the Algerian electric power system 114-bus and the obtained results compared with two other methods, namely, Genetic Algorithm (GA), interior point method (IPM) and other methods in the literature. The result comparisons demonstrate the potential of the proposed approach and show its effectiveness and robustness to solve the ORPD problem.

In the proposed PV-FC hybrid system, the PV generator feeds a variable load through a DC-DC converter controlled by an MPPT control (maximum power point tracking) and transfers energy to the electrolyzer side if possible to produce hydrogen which will be stored in a tank for a later use in the fuel cell (PEMFC). When the PV system cannot completely meet the load demands, the FC system provides the lack of power. The MATLAB-Simulink environment is used for the simulation of the PV-FC hybrid proposed system. Simulation results are presented in order to highlight the performances of proposed hybrid system.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115302233","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}

A main concern with these gadgets is undesired movement between consecutive frames. Video stabilization is a technique with increasing impact for solving this problem. In this paper, a proposal is introduced for robust video stabilization, in particular for on-board cameras in micro aerial vehicles. It is based on a combination of the RANSAC (RANdom SAmple Consensus) algorithm and gray level differences as cost function for local motion parameter estimation, as well as a low-pass filter for global motion smoothing. Experimentation will illustrate about of the robustness proposed solution.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128704073","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 time trajectories of the Zernike moments of the moving subject have been taken as features. Even though Zernike moment orders of about 15 to 20 are required to characterize and/or reconstruct a general 3D image with reasonable fidelity, it has been found that fewer number of moments are sufficient for satisfactory action classification, due to the accumulative nature of video data. In our work, we have obtained greater than 95% recognition accuracy using as low as 3rd order Zernike moments, over the 7 basic actions considered. Recognition accuracy increased to more than 98% with 5th order moments.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124604967","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}

An optimized process for both linearity and efficiency performance improvement using a reconfigurable matching network (RMN) for wideband power amplifiers (PAs) is presented. Long-term evolution (LTE) waveforms modeled as multisine excitations are used to simulate a general purpose PA, assuming that the antenna is perfectly matched. Power added efficiency (PAE) is strongly improved by selecting properly RMN state at the same time as linearity also increases. Furthermore, the adjacent channel power ratio (ACPR) is improved whilst obtaining efficiency enhancement when selecting the optima RMN state for linearity. Both linearity and efficiency are improved simultaneously with this architecture.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122394198","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 advantage of the SECE interface is the load independent power transfer. But the maximum efficiency the SECE interface in combination with the piezoelectric transducer can achieve greatly depends on the electromechanical coupling of the transducer. The SECE interface works very well with weak to mid-range electromechanically coupled piezoelectric transducers. But with strong coupled transducer the power extracted by SECE interface decreases. This paper shows how the SECE interface can be tuned to deliver the maximum power almost independent of the electromechanical coupling factor.","PeriodicalId":168063,"journal":{"name":"2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126633762","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 a last step the parasitic features of a circuit representation are taken into account, resulting in an overview over the system design space that can be covered with this class of architectures.
