The UHD 180-degree images are formed by stitching nine high-definition images captured from individual cameras, mounted in regular geometric structure, covering a FoV of 180 degrees around the acquisition viewpoint. An experimental study is carried out to reduce the computational complexity required by feature extraction and matching which are the most complex tasks in the image stitching process. Based on an early data reduction approach, it is shown that good quality stitching can be achieved with low computational complexity. Overall the proposed system is capable of capturing 180-degree panoramic images of ultra high definition using low-cost cameras and processors, which makes it suitable for applications with highly demanding resolution requirements.","PeriodicalId":232097,"journal":{"name":"IEEE EUROCON 2019 -18th International Conference on Smart Technologies","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125517721","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 machine learning method, using neural network training is used. The obtained results are verified using both established objective measures, and subjective evaluation of the same set, acquired by mean opinion score survey on multiple human subjects. The main advantage of the proposed approach is that it can grade the perceptual quality of the fused image even prior to the completing of the fusing process, in the stage of pyramid decomposition. This also allows implementation of a mechanism that could stop the pyramid decomposition in the most optimal pyramid level, in order to achieve the highest quality output image.","PeriodicalId":232097,"journal":{"name":"IEEE EUROCON 2019 -18th International Conference on Smart Technologies","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122694969","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}

Additionally, sensorless control of electrical machines has been thoroughly investigated in the last decades in order to lower the costs associated with the speed sensors used in electrical drives and increase the reliability of the drive. In the literature, rotor slot harmonics were intensively inspected to obtain information about rotor speed and position. In this paper, a speed estimation technique based on rotor slot harmonics in a multi-phase induction machine was proposed, based on the familiar approaches. It relies on the spectral analysis of the stator current. The most important benefit of the method introduced in the paper is lack of any type of the filter for extracting the specific rotor slot harmonics from the current spectrum. Simulation results that verify the effectiveness of the method proposed were obtained using MATLAB/Simulink.","PeriodicalId":232097,"journal":{"name":"IEEE EUROCON 2019 -18th International Conference on Smart Technologies","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122855755","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 order to estimate this impact, probabilistic load flow method based on Monte-Carlo simulation has been developed. The variables that depend on the vehicles driving cycle have been obtained with data extraction from the 2017 National Household Travel Survey (NHTS). In addition, general household load has also been considered in the simulation. Simulation results show which network components could not withstand the simulated penetration level and what measures can be taken.","PeriodicalId":232097,"journal":{"name":"IEEE EUROCON 2019 -18th International Conference on Smart Technologies","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114148204","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 many contemporary robotic applications, there is a great need to grasp differently shaped and sized objects as well as objects of different stiffness or soft objects. Grippers based on classical rigid-body mechanisms cannot safely manipulate with such a wide variety of objects, as they are stiff and not adaptive. Adaptive gripper proposed here is based on elastic active compliant mechanisms. Via integrated sensors, and actuators active smart gripper changes the shape of its grasping surface and adapts to the object of unknown shape. Concept of a two-finger gripper and a functional prototype of one gripper finger are presented. Sensors are formed by using conductive graphite foam. The machine learning models of tactile foam sensors are presented. Actuators are formed by using a shape memory alloy wire nitinol. It is demonstrated that developed soft gripper concept with integrated active elements can realize multiple grasping patterns. Many potential applications in robotics are foreseen for the novel smart adaptive gripper.","PeriodicalId":232097,"journal":{"name":"IEEE EUROCON 2019 -18th International Conference on Smart Technologies","volume":"37 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117020962","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}

Defect site mostly results in field enhancement and generates partial discharge activities. Investigation is done through the simulation evidences using contemporary software tool COMSOL Mph. to perceive the field enhancement due to the presence of defects.
