By implementing the Q-Learning techniques in the PD control scheme, the pendulum is enabled to improve its online performance and adapt to changes in the parameters of the pendulum model. In a first step, Q-Learning is used so that the control can balance the pendulum towards its inverted vertical position; In a second step, we combine hybrid techniques of Q-Learning and PD control. With this combination, we can bring the pendulum to its inverted vertical position, regardless of the applied disturbance. Finally, the results of the simulation show the effectiveness of the proposed controller.","PeriodicalId":6924,"journal":{"name":"2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76081202","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}

Sensors that integrated an accelerometer and gyroscope to record head and body movements were used. The integration of an accelerometer with gyroscope allowed to detect the movements of the body in the sagittal, coronal and transversal planes. Tests were performed placing the sensors on the head and body to verify that the registration was correct. The results show that it is possible to detect human movements without restriction in the displacement of the body, which is very useful for different applications such as the detection of problems associated with human equilibrium and orientation like disorientation in space, involuntary movements, posture, gait and loss of balance.","PeriodicalId":6924,"journal":{"name":"2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"8 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87386214","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}

Solar cell models help optimizing the fabrication parameters so that increased efficiencies can be achieved, reducing the development and production costs. With this purpose, we have developed a unified analytical model for designing thin film solar cells that takes into account the specific differences associated to thin film solar cells as compared to volumetric conventional cells. In this work, we apply this model to Cu<inf>2</inf>ZnSn(S<inf>1−x</inf>Se<inf>x</inf>)<inf>4</inf> (CZTS) solar cells with ZnO:Al/CdS/Cu<inf>2</inf>ZnSn(S<inf>1−x</inf>Se<inf>x</inf>)<inf>4</inf>/Mo cell structure. Short circuit current density (Jsc), open circuit voltage (Voc), fill factor FF and efficiency (ƞ) calculations have been done for cells with Cu<inf>2</inf>ZnSnS<inf>4</inf> (1.5 eV) and Cu<inf>2</inf>ZnSnSe<inf>4</inf>(1.05 eV) absorber layers as a function of the absorber thickness in the range from 0.3 μm to 2 μm. These results indicate that it is possible to obtain high efficiencies for absorber layer thickness less than 1 μm, whenever the recombination velocity (S) at the back contact is below 10<sup>3</sup> cm/s. Additionally, efficiency as a function of the CZT(S<inf>1−x</inf>Sex)<inf>4</inf> absorber layer bandgap has also been calculated, when the thickness is varied from 0.75 μm to 2 μm. It was determined that the highest conversion efficiency (around 17%) can be obtained for a bandgap around 1.47 eV, thickness of 0.75 μm and back surface recombination S = 10<sup>2</sup> cm/s. It is concluded that reduction of both the back surface recombination velocity (S) and the interface recombination velocity (Si) should be fundamental for achieving very thin (less than 1μm) CZTS solar cells with high efficiencies.","PeriodicalId":6924,"journal":{"name":"2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"219 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78494975","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}

One of the standard techniques providing denoising and extracting features of ECG signals employs one-step prediction. We show that better accuracy can be obtained using UFIR filtering and smoothing. We develop the UFIR-based fast algorithms in discrete-time state-space with adaptive optimal averaging horizon, which is required to minimize the mean square error. In this paper, we exploit ECG measurements and artificial data related to normal heartbeats. Higher accuracy of the developed state-space UFIR smoothing algorithm against the traditional prediction-based one is demonstrated experimentally and by simulation.","PeriodicalId":6924,"journal":{"name":"2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83224007","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 nominal linear model of the LUM is used to perform the parametric estimation.

External and internal perturbations are assumed to be a lumped bounded disturbance and its estimate is used in the design of the controller to compensate its effects.

The problem consists on finding the minimum of a strongly convex function which is unknown but may be measured in any testing point subject to a stochastic noise perturbation. The suggested extremum seeking procedure is based on the estimated gradient obtained by the modified stochastic version of the Synchronous Detection Method. We have added a first order low-pass filter to the gradient estimator to attenuate the noise in the estimations. We prove the mean-squared convergence of the suggested extremum seeking algorithm to a zone around the minimizer.

The algorithm performs image segmentation by binarization, morphological filtering, and region growing, where the binarization threshold is automatically obtained from the input image. After identification of the rhombus shaped indentation footprint, its four vertices are determined using corner detection, which are used to calculate the diagonal lengths and the Vickers hardness number. The proposed procedure has been tested on 185 images of real data obtained by the micro hardness machine Mitutoyo HM-124, mostly from Steel-316 specimens, but also from Hafnium Nitride. Test images include specular-polished and rough surfaces, specimen with artifacts or imperfections, indentations with deformed or damaged edges, and low contrast images. Ground true diagonal lengths obtained in the conventional manual manner by an expert were compared with the results determined by our method. The proposed method achieves competitive accuracy compared to the best known methods, but it is simpler and hence more efficient.","PeriodicalId":6924,"journal":{"name":"2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"36 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83592214","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}
