According to its purpose, DG is used to supply remote electricity consumers. In conditions of market uncertainty in the development of the energy sector, one of the most profitable solutions for increasing the reliability of consumer power supply is to install a small-scale generation near the distant loads. Under such option the risks of energy shortage and loss of power supply from power source of the main network are reduced, reliability of power supply is improved, the energy quality parameters are improved, power and energy losses are reduced. However, the growth of the DG penetration in electric power systems (EPS) has not only positive aspects, but also creates certain technical problems that are associated with fluctuations of EPS parameters as well as with DG controllability under normal and emergency conditions. These problems can be solved but at the cost of more complex EPS dispatch and automatic control. The solution requires new mathematical models to substantiate the development of EPS and power supply systems, to analyze and to manage their state. In this article the authors propose a novel mathematical model for DG planning and optimization basing on integral quality criterion that incorporates power supply quality and reliability.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"46 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116524421","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 main issue we intend to solve using this interactive kiosk in the field of education, as a novelty, is to reduce students’ lack of interest in practical work. The advantage is interaction improvement of the student with the teacher by bringing useful, dynamic and interactive information about the laboratory and the activities carried out here. Last but not least, the low cost can also be considered in the context of growing interest in open source. The web interface is accessible to any type of user and beyond providing information about students’ projects, it offers the possibility of sending an email about the issue of a lab or course followed under the guidance of a teacher working in this laboratory.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132124735","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 most important cause of long-term disability in Europe is cerebral vascular accident (CVA) or stroke. The effects of stroke can vanish after a short period or can remain for the rest of the life depending on therapeutic program. The system developed for this study is not only therapeutically devices that allow the movement of hand for physical exercises controlled by electromyography (EMG) but also record one or more biomedical parameters such as: electromyogram (EMG), electrocardiogram (ECG), pulse wave, heart rate (HR), temperature, respiration rate, non-invasive blood pressure (NIBP) or oxygen concentration in the blood (SpO2). These physiological parameters are selected according to the physician’s prescription and the patient needs. In this paper it is presented an application that refers to the hand rehabilitation of post-stroke. It was observed the cardiovascular system status, analyzing the heart rate variability. During therapeutic procedure it was recorded ECG (1 lead) and pulse wave (using an ear lobe sensor). After that HRV was calculated for each signal. The results were used to determine the stress level induced by the rehabilitation program.","PeriodicalId":343896,"journal":{"name":"2018 International Conference and Exposition on Electrical And Power Engineering (EPE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133752043","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 wide frequency band was tested, (0.1-2.9) GHz, by applying continuous wave stimuli. Significant field strength components were provided and characterized, by using a GTEM cell and adequate expo-dosimetric instruments. The heating rates of the suspensions were measured. Because the recorded values were very low, non-thermal expression of energetic conversion was further investigated by scanning-transmission electron microscopy methods, by various spectroscopic means and by electrical conductivity determinations.

With the evolution of technology, the speed of the cars and the traffic increased. This means that there is a need to predict dangers which can arise while someone is driving. Another direction is to develop autonomous cars that can face the present and the future traffic conditions in order to increase the safety and the fluency on the roads. So, in the present paper it is presented a method of determining the distance to a car that drives in front of our own car. The relative speed is also possible to be determined with respect to it. The image, taken with a front camera, is classified using a Convolutional Neural Network, namely YOLO [1] (You Only Look Once) and after the searched object is detected, the distance is estimated counting the number of pixels in a bounding box which fits the detected object. The distance is further corrected by using Canny edge detection and HSV color space.
