In the manufacturing industry sectors, manual lifting is commonly practiced even though mechanized material handling equipment are provided. Due to this repetitive lifting behavior, it will contributes to muscle fatigue and low back pain that can lead to work efficiency and low productivity. This will cause great losses to the company and to the country. The purpose of this study is to investigate changes in the surface electromyography (sEMG) signals during repetitive manual lifting for different twist angle values. The EMG signals are taken from right Biceps Branchii of five healthy subjects (age range 21 - 25 years) while performing symmetric and asymmetric lifting of twist angle 0° and 90° at lifting height of 140 cm with load mass of 10 kg. The analysis is done by applying time-frequency distribution (TFD) which is spectrogram technique to represent the EMG signal in time-frequency representation (TFR) before displaying the instantaneous voltage, Vrms (t) value. This study found that symmetric lifting requires less force to lift the load and that asymmetric lifting has faster tendency to experienced fatigue. This study concludes that the twist angle has a significant influence to the muscle performance of right Biceps Branchii.","PeriodicalId":302732,"journal":{"name":"2015 International Symposium on Technology Management and Emerging Technologies (ISTMET)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133627371","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}

Digital Substation is one of the key systems in Smart Grid domain where information regarding power system network are obtained to execute various functions in a Smart Grid domain. Interoperability, which is the ability of two or more devices to exchange information with each other, is a vital feature for digital substation. To ensure interoperability in a multi-vendor environment for Digital Substation, it is desirable for devices to able to communicate using an open communication standard that is implemented internationally. For power utilities, such as Tenaga Nasional Berhad (TNB), it is imperative to ensure that interoperability between multi-vendor devices is thoroughly tested before the devices are deployed in actual digital substations. This paper will highlight a case study by TNB to verify and validate interoperability between multi-vendor digital substation devices using an open communication standard which is IEC 61850.","PeriodicalId":302732,"journal":{"name":"2015 International Symposium on Technology Management and Emerging Technologies (ISTMET)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122695237","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}

The meteorology data consist of direct solar irradiance were for 2013 and the satellite data were global solar irradiance from year 2000 till 2004. The estimated global solar irradiance were then compared with observe satellite data and their performance were judge by using statistical indicators, including root mean squared error and mean percentage error. The 5 cities studied in Malaysia includes Kota Kinabalu (KK), Kuching (KC), Ipoh (IP), Alor Setar (AS) and Kuantan (KU). The yearly average of hourly solar irradiance for all 5 cities throughout a year lies between 193 W/m2 and 208 W/m2. The highest solar irradiance has been estimated at 216 W/m2 in the month of March due to the dry season, and the minimum solar irradiance is predicted in the month of December is 164 W/m2 that coincides with the rainy season in Malaysia. Results show that the proposed global and direct solar irradiance models present good regression coefficient (R2) value of 0.9661 and 0.9549 respectively. The average diffuse solar irradiance cast over these cities were 3.0% (correction factor) of global solar irradiance. Since Malaysian government are focusing on renewable and clean energy, these models and analyses will benefit the government and education department for further development in solar technologies.","PeriodicalId":302732,"journal":{"name":"2015 International Symposium on Technology Management and Emerging Technologies (ISTMET)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132518515","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}

Experimental results of the quickest and higher percentage of FOG derivatives leach out from green part is being analysed. The green part will undergo two different solvent debinding (Heptane and Hexane) with three different solvent temperature. Debinding times was set for 10 hours and every 1, 3, 6 and 10 hours the green part will undergo weight measurement for monitoring the weight loss percentage of green part. It seems that both solvent indicates good diffusion and dilution for extracting the FOG derivatives out from the green part in producing brown part where no sign of part crack or swelling during and after solvent debinding. Energy Dispersive Spectrometer (EDS) for element detection and Scanning Electron Microscope (SEM) analysis also being perform which indicates the good pores build up.

Theoretical and empirical contradictions in literature exists on the relationship between the variables of the study, but these variables are still very important in determining the CO2 emissions. In line with the Environmental Kuznets Curve (EKC) hypothesis it is expected that economic growth will improve environmental quality in the long-run. Similarly, it is hypothesized that financial sector development will reduce the CO2 emissions which will lead to the betterment in quality of environment in case of Malaysia during the study period. It is supposed that increase in the imports of the country will focus on the environmental friendly technology and openness will decrease the level of pollution. The relationship and impact of the variables is unclear and controversial in different case studies and also panel studies, which make it a center of discussion for further research. The proposed study will employ vector error correction model (VECM) approach to investigate the relationship between the variables. For the robustness of results it is suggested to employ impulse response function (IRF) and variance decomposition (VD).","PeriodicalId":302732,"journal":{"name":"2015 International Symposium on Technology Management and Emerging Technologies (ISTMET)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125612874","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}

Looking at the significance of CE, research communities from the developing countries are also paying substantial attention towards corporate entrepreneurship. The literature has evolved from entrepreneurship to corporate entrepreneurship and is now moving towards sustainable corporate entrepreneurship. Initially, it was considered that corporate entrepreneurship had three main dimensions, such as innovativeness, proactiveness and risk taking. Later, competitive aggressiveness and autonomy were also introduced as corporate entrepreneurship dimensions. It has been observed that these dimensions play an important role in the economic growth for large businesses. Similarly, sustainability has also been getting attention, after it had been emphasised in modern literature and by various international organisations. Sustainability covers social, environmental and economic issues, thus recommending the importance of both corporate entrepreneurship and sustainability. This study aims to propose a framework of sustainable corporate entrepreneurship and firm performance for Malaysian public listed firms. This proposed framework can be generalised to apply to other countries. Sustainability has been incorporated with corporate entrepreneurship. In order to measure the entrepreneurial activities, this framework proposes firm performance as a dependent variable for a sustainable corporate entrepreneurship framework.","PeriodicalId":302732,"journal":{"name":"2015 International Symposium on Technology Management and Emerging Technologies (ISTMET)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125416055","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}
