System will then be excited by known sinusoidal input to generate describing function model of the stabilized closed-loop system. Linear lead-lag controller will be designed based on this describing model followed by optimization of linear lead-lag controller over various operating regime. Inverse describing function will be carried out to invert controller gains at various operating regime. Nonlinear controller will be experimentally verified and compare with linear controller.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126770613","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}

Along with this development came the increasing needs for more qualified personnel and technocrats. The task to provide professional trainings for the required manpower was given to the Higher Education Institutions. Playing this important role, UiTM for one, has since then conducted the Quantity Surveying Programme to cater for the mushrooming construction industry. The purpose of the programme was mainly to generate the number of professionals suitably trained to perform the contract administration works including the technical estimations for construction developments. Nonetheless, educating the adult students is always far more challenging and complex than teaching schoolchildren. Among the important functions of the higher level institutions is to train our future workforce by providing them with the relevant knowledge and skills. For this reason, graduates from the QS programme must be able to meet their professional expectations and challenges of the future. The aim of this paper is to study the important role of Bloom's taxonomy as applied in the higher level institutions specifically for degree programme offered by the Department of Quantity Surveying UiTM. The reviews also explain the relevance between the assessments in the Bloom's taxonomy with the Quantity Surveying degree programme. The findings, would provide the conceptual understanding about the Bachelor of Quantity Surveying (Honours) programme being taught at UiTM. This has to comply with the learning outcomes as stipulated in Bloom's Taxonomy which should also reflect the construction industry's needs.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123875009","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}

Sulphate may exist in soil, ground water, sea water and effluent discharge by industry. As a result of sulphate attack, cracking, expansion, spalling, loss in volume and strength may take place. To minimize such occurrence, several factors need to be considered such as water/ cement ratio, permeability of the concrete, condition of sulphate exposure, cement composition, curing condition, etc need to be accounted. The idea of this study is to compare the behavior of normal concrete containing steel slag aggregate and normal aggregate under the exposure of two types of sulphate ions namely, natrium sulphate and magnesium sulphate with 0.3molar 5 % concentration for a period of twenty weeks. The durability of concrete containing steel slag i.e. changes in physical, volume and strength after the immersion process has been observed. The result of different water cement ratio of 0.47, 0.52, and 0.55 and steel slag aggregate replacement of 10%, 50% and 100% of total aggregate proportion are presented and analysed. From the result, it shows that the durability of steel slag aggregate (SSA) and natural aggregate (NA) concrete has the same performance.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130242448","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}

With the increase in natural disasters like tsunami, typhoon, and rise in water level from global warming, it is very important for engineers to model the environmental load accurately. Eight fixed offshore jacket platforms with four, six and eight-legged configurations and with K and X type bracings were chosen for this study. Three sets of environmental data for ten, fifty and hundred year conditions covering three regions in Malaysia were selected. Peninsular region was observed to encounter the highest environmental loading of about 21 MN followed by Sabah region with 3.6 MN and Sarawak region with 3.4 MN. The dominant load direction was from North and North East from the open South China Sea. This was logical since most of the fixed offshore platforms in Malaysia are located at about 30 to 150 km distance from shore. Apart from the location, the size, appurtenances and marine growth of the fixed offshore platforms impacted the load. From these findings, engineers can now use different design approaches and redundancy arrangements for the different regions in Malaysia for reducing the cost without compromising the safety of the structure.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134424890","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}
