This study uses data mining techniques to study the job requirements of network engineering, network administer, and IDC network & operation, which are the main possible work positions for the college students in major of network engineering. First the percentage of job positions among these three job requirements are calculated, and second the districts with the highest and lowest requirements in job positions of network engineering, network administrator, and IDC network & operation are presented. The results show that network administrators are the highest requirement of job positions, and the other two jobs requirements are nearly the equal. In the sixteen district of Beijing, Haidian and Chaoyang district has the highest possibilities that student will work at, while Mentougou district has the lowest possibilities. This work provides teachers and course progamme directors with information that might help them to improve the education programmes in the college and provide student with information that might help them to understand which district that they will work at.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72771796","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}

There are various standard intersection applications in the world and our country. Only capacity analyzes are not enough to determine intersection type. Factors such as traffic safety, land topography, cost, development plans, expropriation, local demands, history, cultural and touristic characteristics of the area, and the requirements of the public authorities are also necessary factors to be assessed. However, traffic problems at intersections, which are designed in a standard way without considering the above-mentioned factors affecting intersection design, require different solutions especially in these parts of highway. In this study, existing problems were identified on the basis of traffic counts and field observations on a sample roundabout in Karabük Province, 100.year neighborhood, at the intersection of 1002 Street and 1003 street. A new intelligent roundabout design was applied and the applicability of the new intersection model in addition to capacity and safety has been demonstrated and optimized using Ptv-Vissim and Autoturn software’s. The revealing results are; it is necessary to design the intersections considering the specific parameters of each intersection instead of standardization and it is necessary to adopt new approaches (intelligent crossroads etc.) in intersection design.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89080910","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 requires the development of a reliable non-destructive method for assessing their condition, including during operation, what is of no less importance since it allows to reject materials with defects even before structural elements are made of them. The evaluation of possibility to use the acoustic emission (AE) scanning method based on EMA type equipment for fiberglass specimens was conducted. Numerous experiments were performed on scanning specimens in the longitudinal direction, in which each of the AE sensors alternately acted as an emitter of test signals. Of the six specimens tested, three contained an integrated center element simulating an acoustic piezoelectric transducer. Tests have shown that with AE scanning it is possible to distinguish acoustic properties without loading specimens in the presence and absence of such an integrated concentrator and to quantitatively assess the damage for material with concentrator. Also, the unique for EMA systems automatic prediction of destructive loading for both materials were tested during specimens tension up to crash. The importance of the results obtained for creating a methodology of composites testing using AE scanning technology and providing clear criteria for assessing damage is noted.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84502135","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}

Significant challenges remain to be overcome. This paper examines the reforms through the lens of New Institutional Economics in order to determine how weak institutions have so far confounded seasoned local investors and international advisors, by looking for the presence of excessive transaction costs. The reform environment is based on Williamsons 4 levels of social analysis and subjected to evaluation based on four areas deemed critical for reform success, namely property rights, market structure, conflict resolution mechanisms and policy implementation capabilities. The study is restricted to investors in electricity distribution companies, and the presence of high transaction costs used as proxy for institutions in need of further improvement. The study finds that providing quality asset performance data and changing a culture that tacitly accept electricity theft and late bill payment, will reduce the transaction costs associated with defining and protecting Investors property rights. However, the regulatory environment must mature to enjoy the confidence of government, consumers and investors, who continue to remain optimistic.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76231747","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}
