Although renewable based DGs can largely improve the figure of reliability, they may also harm it due to their fluctuating nature. One of the key characteristics of smart distribution systems that could resolve this issue is the demand side management (DSM). DSM refers to any activity done by the utility or the customer to influence load behavior. There are many effective aspects of the DSM that, when addressed efficiently, could benefit both utilities and consumers. In this paper, a reliability assessment of a smart distribution local load system will be studied, including the DSM and the integration of wind and solar energies. The impact of the wind and solar energies on the reliability of the local load will be addressed and compared to base-case reliability. Actual wind speed data and solar irradiation are used in modeling wind and solar power outputs to include seasonal variations. Then, the DSM concept will be implemented to assess the increase in load reliability. Two main DSM aspects are studied and simulated which are load shifting and peak clipping aspects. The Monte Carlo Simulation (MCS) will be utilized to evaluate the reliability for residential, commercial, and industrial loads.","PeriodicalId":149580,"journal":{"name":"2016 13th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130696299","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}

However, since it is not possible to determine the junction temperature directly in standard applications, an indirect method for determining Tj can be applied.

The raw EMG signals are rich in information but they have to be amplified, converted to a digital form and filtered to be useful in the diagnostic of myopathy. So, to create an EMG database a low cost and high performance acquisition board is designed. An instrumentation amplifier AD524, an Arduino board(to have a real time analogical to digital conversion) and a Wavelet based filter processed on Matlab software were used to obtain an exploitable EMG database. The correctness of stored signals is evaluated by comparing them with themselves when they were stored on computer using a digital scope(metrix 0X6062-II). An SNR metric of 74 dB is calculated, this SNR value is not sufficient to decide of the high performance of the acquisition board. Thus a turn back to compare the representation of a square signal obtained either with the designed board and with the digital scope was done. A calculation of some signal's parameters as period and amplitude shows that the new acquisition board reproduce the input signal shown directly on the screen of the digital scope more closely than that reproduced with the scope's generated data file.","PeriodicalId":149580,"journal":{"name":"2016 13th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131324209","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 this approach, the interior of the catalyst housing acts as a wireless channel between two end devices of a communications system. It was shown that, depending on the transmission channel characteristics, the properties of the catalyst such as its state can be inferred from the properties of some random function such as the received time response (a random function of time) or its Fourier transform, the received spectrum (a random function of frequency). This publication presents results on the resolution of the measurement method when the normalized cross-correlation function between the received spectra with respectively unloaded and loaded catalyst is used as random function. In particular, we have investigated the influence of the transmit signal power.

Siegl, J. Gerstmann","doi":"10.1109/SSD.2016.7473739","DOIUrl":"https://doi.org/10.1109/SSD.2016.7473739","url":null,"abstract":"The investigation of fluid phenomena is of high interest in the management of cryogenic liquid propellants used in space launch vehicles. In order to efficiently design cryogenic propulsion systems or orbital cryogenic propellant storage facilities, experiments concerning fill-levels, bubble formations and boiling have to be conducted in microgravity and on earth. Thus measurement devices are needed that can give insight into the spatial distribution and the behavior of the fluids inside the cryogenic system. One possibility to observe liquids inside a given volume without intruding into the system and thereby disturbing the flow characteristics is to use a capacitive system with electrodes embedded into the walls of the vessel. In this paper experiments with such a system at cryogenic temperatures are presented. To simulate the behavior of rocket fuel in space a cryostat was filled with liquid nitrogen and by way of controlling the pressure inside or locally heating the liquid, bubbles were created. Two capacitive measurement systems have been submerged into the cryogenic liquid to monitor the location and size of bubbles inside the liquid and to observe the state of the liquid/gas interface. One system consisted of a cylindrical polycarbonate ring with four embedded electrodes and a polycarbonate lid at the top carrying one ring-shaped electrode. Many small bubbles thus could be trapped and coalesced in this half closed cylinder (bubble trap) forming a big single gas volume. The other system was a polycarbonate ring with 16 electrodes arranged along its circumference. The task of these systems was to measure the filling level inside the cylindrical bubble trap and to detect and quantify rising bubbles inside the cryostat by measuring the mutual capacitances of selected electrode pairs. To interpret the measurement results, FEM simulation results were used to generate a characteristic curve for the relationship between filling level and measured capacitances. To validate the results, two cameras were mounted inside the cryostat which allowed the simultaneous recording of the filling level and the existence of bubbles and bubble streams. We observed a good agreement between measurement and simulation. Overall the suitability of the system for cryogenic applications has been successfully demonstrated.","PeriodicalId":149580,"journal":{"name":"2016 13th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181722","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 variations of CF2 parameters P, c, k, Q and ρ0 are however vital to its performance. In this paper, we used the multi-objective particle swarm optimization (PSO) approach to optimize these parameters. The computation of the optimal parameters is restarted in each new position of the robot. PSO is used to minimize the distance between this position and the target and to maximize the safe distance between this position and the obstacles. The effectiveness of the method is demonstrated by computer simulations in the Webots environment. Simulations are carried out in various known and unknown environments. In the known environments, the obstacle position is recognized by the robot at the beginning of navigation and the path planning is global. But in the unknown environments, the robot localization is based on the sensor readings and the path planning is local.","PeriodicalId":149580,"journal":{"name":"2016 13th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123326272","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}
