In order to enable this feature for their infrastructure, MNOs are upgrading their core, transport and radio acces network sites for better-differentiated QoS support. In this paper, based on real-world network test experiments in one site of Turkey, we present how the performance of LTE base stations behaves when higher priority QoS to some LTE users are enabled. In order to evaluate this we compare the throughput performance of priority users with respect to normal LTE users in different scenarios including various frequencies and bandwidth. Our results demonstrate that even though a pre-configured resource allocation can be given to priority users in a commercial setting, real network performance results can differ due to availability of other normal LTE users and differences in obtained QoS Class Identifier (QCI) levels of wireless network's conditions.","PeriodicalId":6482,"journal":{"name":"2018 5th International Conference on Electrical and Electronic Engineering (ICEEE)","volume":"33 6 1","pages":"408-412"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81177069","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 these systems most programs are comprised from loops, and this shows the importance of compiler optimization. In this paper we have carried out loop reduction using calculation and fusing two loops and transforming them to one loop that caused data locality increase and reusability, and decreased loading data from memory, thus increase speedup. We have applied this technique on several feature extraction algorithms, such as mean and variance and some similar algorithms like covariance and third moment that are used in content-based image retrieval systems. This technique approximately increases efficiency of two loops method twice. In addition, we have calculated the combination of these three functions. In this way, we have observed that the combined version also increases the efficiency twice.","PeriodicalId":6482,"journal":{"name":"2018 5th International Conference on Electrical and Electronic Engineering (ICEEE)","volume":"13 1","pages":"334-339"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74262454","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 university receive its electrical power supply from the Berakas Power Management Company (BPMC), a local utility company, through an 11kV/415V transformer. This distribution transformer and its switch room were installed at different location but very close to each other. The goal of this investigation was to measure the low frequency magnetic field radiated from the switch board and electrical appliances located around the administration office. In this case, the magnetic field was measured using EMDEX II meter with the aid of Linda Wheel equipment. The measured magnetic fields near the switchboard, around the induction motors, outside of the switchboard and at the admin office were found to be 96.22mG, 11.91mG, 12.4mG and 8.4mG, respectively. These values of magnetic fields were found to be within the acceptable limit provided by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) standard. In addition, a mathematical model was developed based on the lateral distance with higher determination of coefficient.","PeriodicalId":6482,"journal":{"name":"2018 5th International Conference on Electrical and Electronic Engineering (ICEEE)","volume":"70 1","pages":"293-296"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73218460","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 challenge is to transfer power in a full capacity and reduces power losses to minimum range. This lead to a necessity of studying the problems that affect on power system stability for Ensuring optimal use. One of these problems is the oscillations of low frequency. Inter-area oscillations are critical and should be detected and damped efficiently in order not to cause a blackout in the power systems. With this respect, it is of great importance to deal with this problem so that power quality of the power systems is continuously supplied by the power system operators. The major objective of this paper is to investigate the oscillations associated with the operation of the system and processed it in inter-area mode. The studied model is a Kundur which is a power system with two area used with implementation of each of selected \"Flexible-Alternating- Current-Transmission FACTS devices which were implemented to a specific place in the network to check dynamic performances of Thyristor controlled series compensator (TCSC), Static synchronous compensator STATCOM and Static synchronous series compensator SSSC on inter-area and record the results.

Atomic layer deposition (ALD) Al2O3 can be used as passivation layers in p-type and n-type silicon solar cells, which can increase the lifetime of minority carriers and reduce the surface recombination velocity. Field- effect and chemical passivation are two effects in ALD Al2O3 on silicon surface. In this article, we use PC1D to simulate the silicon solar cells with the application of ALD Al2O3. In the p- type silicon solar cell, ALD Al2O3 is applied at the back surface, and the conversion efficiency is increased from 17.5% to 20.3% The simulation result indicates that the field-effect passivation is more important. In the n-type silicon solar cell, ALD Al2O3 is applied on the p-type emitter at the front surface, and chemical passivation may play more important roles.","PeriodicalId":6482,"journal":{"name":"2018 5th International Conference on Electrical and Electronic Engineering (ICEEE)","volume":"73 1","pages":"172-182"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86402938","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}

Due to the grounding grid is always in the complex soil, it faced the varying degrees of corrosion threat. When the soil resistivity is high, engineers usually use an impressed current cathodic protection (ICCP) system to suppress corrosion. But the existing design and installation process of ICCP systems has some drawbacks. Engineers can only get the effect of the system after ICCP systems installed and run. If the effect is not up to standard, they need to re-design and re-install, which will waste a lot of manpower and resources. This paper mainly analyses the ICCP systems and proposes a new method to design the substation grounding grid ICCP systems by COMSOL Multiphyscis simulation software, which can effectively solve the above problems.","PeriodicalId":6482,"journal":{"name":"2018 5th International Conference on Electrical and Electronic Engineering (ICEEE)","volume":"1 1","pages":"193-197"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77355201","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}
