The inertia constant of a system can be a significant tool for investigating the frequency stability of a system and the frequency transient of power system is a vital index for power system operation and research. The dynamic frequency characteristic of power system is the basis of many important design works such as the design of under frequency load shedding scheme. Therefore, it is obvious and essential to analyze the dynamic frequency characteristic of BPS before countrywide blackout after disturbance. This paper first analysis real time frequency transient and determine the system inertia. Secondly it shows that maintaining nominal level of inertial reserve in real-time operations with unit commitment which can be crucial to ensure stable, secure and reliable operation of BPS. Beside this under frequency scheme should be revised and controlled. BPS network disintegration along with rate of change of frequency should be ensured for adaptive as well as self-healing of the power system.","PeriodicalId":123939,"journal":{"name":"2015 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125107593","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}

Successful realization of MCU based products depends on the sound understanding of architecture, instruction and interfacing of the MCU, which can be effectively acquired with the help of a `Microcontroller Learning System (MLS)'. The MLS provides facilities to enter program codes and data into memory; program execution and debugging; checking and changing memory/register contents; breadboard/edge connector for prototyping interfacing circuits; and viewing the result on display devices. This paper presents the design and development procedures of an 89S52 MLS system along with examples to establish its effectiveness in learning microcontroller hardware and programming. We designed, developed, and tested a prototype MLS system named MicroTalk-8051 Trainer.","PeriodicalId":123939,"journal":{"name":"2015 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123889759","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}

Input current is chopped in this converter at high frequency during both cycles by a single switch to get step up/step down conversion. Comparison is made between reported and conventional circuit under same load and operating conditions. This proposed circuit shows better performance. The efficiency of this converter is also high. Any other control scheme is not required to achieve these advantages.","PeriodicalId":123939,"journal":{"name":"2015 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128593439","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}

Euler's rotation technique is used to modify the wave vector and Hamiltonian matrix in conventional [100] crystal orientation. It is found that there is a substantial correlation between magnitude of strain and optical gain spectra. From the MATLAB simulation results, it can be settled that the energy band dispersion profile, momentum matrix and optical gain deviates exclusively with the increase of strain magnitude. The regular optical gains are inspected as 2700, 2810, 3080 and 3300 cm-1 when the well is compressively strained by 0.50, 0.90, 1.15 and 1.60% respectively at the carrier injection density of 2.5 × 1018 cm-3 which shows that highest optical gain and lowest effective mass are attained for 1.60% compressive strain.","PeriodicalId":123939,"journal":{"name":"2015 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132603388","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}

Hence, now days, accessing data in an acceptable time is one of the biggest challenges in centralized database. In centralized databases, the records can be categorized according to the access frequencies; least accessed records (cold data) and most accessed records (hot data). In a study it shows that more than 90% cases query are requested for hot data, and in case of insertion operation, 99% are done on hot data. Thus categorizing of the data set may improve data accessibility. In this paper, we are proposing a data clustering mechanism based on data access frequency. We have considered only the hot data and the cold data. Here we divided the whole database into two separate files. The first file contains only hot data and the second file contains only the cold data. The time period of hot and cold data will vary for different application domains. The database engine will have direct access on the first database file and in case of unavailability of data; the database engine will look for the second database file. Finally, the experiment result shows how and why data accessibility time should outperform than other available data clustering techniques.","PeriodicalId":123939,"journal":{"name":"2015 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668485","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}
