The proposed controller is robust for sudden change in loads and more efficient. Most of the industries run with critical loads, so there is always a need to supply better quality of inverter output voltage waveform. A mathematical model of the system is derived using state space modeling. Using the model, a design procedure of controller implementation using the state variables necessary to obtain a stable system is developed. It can be operated for both linear and non-linear load conditions very effectively. It reduces steady state error and is easy to implement. Load voltage regulation is also found to be within the standards. The dynamic nature of the controller is verified. A phase trajectory is plotted to show the nature of the SMC characteristic in reaching the origin. Frequency response characteristics are plotted to realize the state variables to obtain stability. The simulation work is performed in PSCAD/EMTDC version 4.6. and the system stability condition is analyzed from frequency response plots obtained in MATLAB R2012b platform. The proposed controller can be effectively used in all high power industrial applications.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122962567","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}

MoC mainly oversees the construction and operation of ITPC which provides “Wireless Internet service” in Iraq. ITPC is the main state owned company that involves in providing internet service to the public. ITPC has regarded that last mile connectivity by wireless broadband access as a cost-effective solution. In this context, WiMAX has been chosen to support the required Quality of Service (QoS) to the end users. ITPC also has chosen WiFi for last mile access. In this paper, we propose a design for ITPC WiFi network for Baghdad city based on location reality to offer internet service. We have modeled and simulated the ITCP WiFi network using OPNET 14.5 simulator. Specifically, two scenarios of ITPC WiFi network have been designed, devised and taken up for analysis. The scenarios are as follows: (1) Designing ITPC WiFi network deprived of end to end QoS arrangement and (2) with end to end QoS arrangement to enhance the performance. Both the scenarios are investigated using various types of traffic and comparisons have been performed. Our studies have shown that better performance can be obtained when ITPC WiFi network exploit E2E QoS solution. Also, it is demonstrated that delay endured by the network gets reduced by 48% and the throughput increases by 8%.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123130888","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 consistently passes, we have no restrictions for the data or data we get and this is an immediate aftereffect of the propelling advancement and the need to comprehend the necessity for extra. The proposed configuration uses focal thoughts of Big Data, that is, Data warehousing, Data mining and Machine learning. Cloud is utilized to make a dispersed database for multilateral access of medical records. Show and stacking of data is done by means of a web interface, which is utilized by the doctor's facilities. The data is sent and got by means of a REST API which goes about as an arbiter between the warehouse and the front end application. The warehouse (MongoDB), which is particularly offline, is the data warehousing unit which will go about as both the operational database and the analytical database. Cloud Era will go about as the stage for change and preparing of data into clusters for data mining and machine learning algorithms. The data sets are mined and exchanged to apache Spark for the last stage, i.e., Machine Learning for reproducing germ line and somatic gene therapy. The libraries to be utilized are Spark MLlib, Tensor Flow, Theano, Keras and Scikit Learn. The prepared data is mimicked utilizing MatPlotlib as GUI library. This stage is simply non-commercial and is implied for logical experimentation and instructive purposes.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122509028","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}
