The FLG films were grown on evaporated polycrystalline nickel films under a mixture of argon and methane with a relatively large-flow and for very short deposition times. The experimental parameters such as the argon/methane ratio and temperature were varied from 800 to 1000 °C, to obtain the optimal FLG deposition parameters. We were able to obtain relatively large area (1 × 1 inch) FLG films comprising 3-5 graphene sheets. Additionally, early attempts to make suitable graphene/SiO2/Si electronic devices are also reported.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"158 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116773268","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}

This work focuses on obtained results of acoustic field as close as possible to those real measurements, with all this process entails: geometry, the definition of materials piezoelectric, the FEM equations governing the physics of problem and the resolution of the mesh.

This paper presents a method to embed a color image as an invisible watermark into a 3D anaglyph image, for the protection of intellectual property of this type of digital material; the insertion algorithm is performed in the DCT domain using the QIM-DM method in order to achieve the maximum imperceptibility of the watermark. Results demonstrate highest robustness of the algorithm to JPEG compression, impulsive noise, Gaussian noise, as well as high imperceptibility of the watermark obtaining average values of about 40dB in the PSNR between the original and marked anaglyph images.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130498554","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 most critical issues in the car is the area where the tires are in contact with the ground, these are the only points of contact between the vehicle and the road. The importance lies in the fact that keeping the tire contact patch within the operational parameters ensures the safety, comfort and maneuverability of the vehicle. There are some techniques to measure the tire contact patch, but the operating conditions of the car make impossible the implementation; so in this work the tire contact patch is obtained by the frustrated total internal reflection phenomenon and with the measures of 12 sensors in the car, a Neural Network is trained and tested. Thus, a soft sensor that accurately estimates this variable is the main contribution of this work.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114333052","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}

There are different types of motor rehabilitation carried out depending on the type of lesion and the patient characteristics; they can be grouped into passive rehabilitation, when exercises are performed with the help of the therapist, and active rehabilitation, when the patient must performs the exercises all alone. In passive rehabilitation, different tools are used to help patients, one of them is electrostimulation. Electrostimulation however is currently used before or after the exercises prescribed by the therapist. This paper describes a system that generates percutaneous electrical stimulation signals, which can be used, while the patient gets a session of active rehabilitation, increasing the efficiency of the exercises performed by him. Partial results of this research will allow handling a specific type of electrostimulation for different bending angles for the lower limb.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132252720","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}

As a result, we obtained a calibration that allows to track the pose of a webcam within the working space of a stereo-tracker.

The photocatalytic characterization of ZnO thin films was performed by testing the degradation of an aqueous solution containing methylene blue (MB), at a concentration of 2.5×10-5 M, under UV irradiation, (15W Germicidal-UV lamp) for periods from 1 to 5 h. Absorbance of the solutions was measured by an UV-visible spectrophotometer at a wavelength of 664 nm. The variation of concentration of MB as a function of the irradiation time was calculated from the absorbance versus concentration calibrated curve. All films were characterized by XRD (X-ray diffraction), and ultraviolet-visible spectrophotometry.
