The relay protection has an important role to protect a power system from different faults. Coordination of relay protection minimizes the operating time of relays and prevents mal-operation.The Directional Overcurrent Relays (DOR) are used for the protection of the radial distribution network with embedded DG. This paper presents coordination of the directional overcurrent taking into account faults in different places of the power system. The setting of directional overcurrent relay has two parts, i.e., an overcurrent relay and directional element. The coordination of overcurrent relay is based on the operation of relay and time-current characteristic curve.The case study is based on a real distribution network that consists of two CHP generators with 3 MW capacity, and the simulation is performed in ETAP software.","PeriodicalId":339990,"journal":{"name":"2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131499425","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}

To achieve this goal, a significant number of computational methods have been proposed, which can be categorized as Network-based and Non-network-based methods. Since network-based methods have a lot of advantages, this problem can be modelled as a network-based recommendation system. In this paper, we propose an effective approach, RCDR (Recommender Based Computational Drug Repurposing), to prioritize candidate drugs for diseases. Initially, we use drug and disease similarities to build a new drug-disease score matrix. Then, we adopt a collaborative filtering model to recommend which disease can be treated by the new drug. The experiment results show that RCDR proposes well performance compared with other state-of-the-art approaches.","PeriodicalId":339990,"journal":{"name":"2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131706922","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 type of faults leads to the malfunction of current differential relays, while the probability of the relay performance error becomes negligible by using a fuzzy logic system along with the changes in per-unit values and the slope of the differential relay, and consequently choosing the best stability characteristics. In the proposed algorithm, the sensitivity, operation reliability, and performance speed for several types of faults including internal faults and even the high-resistive faults are maintained in the satisfactory levels. The algorithm is also suitable for external faults with the saturation of current transformers (CTs), and it improves the relay performance. The effectiveness of the algorithm is verified in EMTDC/PSCAD software program, and the obtained results are compared with those of conventional methods.","PeriodicalId":339990,"journal":{"name":"2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114446428","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}

Furthermore, selection of an optimal path for transmitting sensed data to the base station is significant. This paper presents a new method called optimal relay node selection, which selects two optimal relay nodes based on residual energy, failure probability, distance to relay node and total distance to base station for every collector node. Analytic hierarchy process method was used to determine the weights of relay nodes and Promethee method was used for outranking them. Furthermore, when a primary relay node fails, this method selects the secondary for providing fault tolerance against path failure. The results show that the proposed method outperforms existing algorithms in terms of First Relay Node Dead, Half Relay Node Alive, energy efficiency and throughput.","PeriodicalId":339990,"journal":{"name":"2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033608","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}

Given the importance of induction machines in the industry, maintaining and protecting them is essential. One of the ways to keep such engines in check is to continuously monitor their health by continuous monitoring of the values of its structural parameters. In this paper, an engine model is estimated using the extracted data from the engine, which includes the effective values of the stator current and the power factor and the application of the colony helium algorithm.

However, the accuracy of the proposed methods remains a challenge in this field. One of the proposed methods for age estimation, which has a higher accuracy than other available methods, is the use of i-vector for automatic age estimation of the sound signal. This method uses one UBM for Gaussian Mixture model. In this paper, by increasing the number of UBMs, the Gaussian Mixture model is optimized and the accuracy of age estimation is improved. Using multiple UBMs with different Gaussian components, for each speaker multiple i-vectors corresponding to each UBM are extracted. Given that, the age of the person is estimated several times and the average of all the estimations is taken as the age of the individual. Also, the results of many experiments in the age estimation, show that PLP features can increase the accuracy of the individuals estimated age. So the second suggestion is to use this features in age estimation. Finally, to enhance the distinction of voice features, the mapping of features was introduced to a new environment; the mapping relationship to this new environment was obtained by training a deep belief network. The proposed algorithm was tested on the NIST 2004, NIST 2005 and NIST 2008 databases. In contrast to single UBM method, the results for the proposed method show a Pearson correlation of 0.8 and a mean absolute error of 5.14, suggesting a %6.67 and %17 improvements in Pearson correlation and mean absolute error, respectively.","PeriodicalId":339990,"journal":{"name":"2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121914409","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}

Therefore two indices namely voltage profile and congestion management have been considered. Photovoltaic units and demand response programs are installed in demand side. These resources inject active power at load buses and reduces from current flowing in lines. So, it increases voltage magnitude at load buses. For congestion management with these resources exist same reason.
