Design and Analysis of a Drive Train System for a Small Race Car

The project is a design and development project of a drive train system for a Formula-style race car. The main objective is to replace the current Universiti Teknologi PETRONAS FSAE (Formula Society of Automotive Engineers) car chain drive system to the gear drive system. The project was conducted with the target of designing the systems for entering a Formula SAE competition and the design has to abide withFormula SAE rules and regulations. This report focused on the design and analysis processes of the drive train system using relevant vehicle dynamics theories and formulas and heavily utilized computer aided engineering tools such as CATIA. No modifications were allowed to the engine as well as the transmission (gear box) due to limitations on the drive train. The design of the drive train was based on gear sizing calculations as part of the car performance analysis. The results include the determination of final drive ratio, maximum velocity, and idle changing gear speed and also the reliability of the new drive train system, which is the gear drive system. The assumptions for certain parameters such as coefficient of drag, frontal area, and overall mass of the car was based on similar existing Formula SAE race cars in order to begin with proper design calculations and performance predictions for the designed race car. The designs of the drive train component including engine drive shaft, bevel gear (ring and pinion), differential housing and bearing based on the performance requirements and analysis. Finally, the report elaborates on the positive benefits and gains from the project and some recommendations on potential improvement and possible new design

ERPS-management accounting practices fit, antecedents, and user satisfaction

Fit between system functionality and task requirements is important for realising full benefi t of the information system and eventually, ensuring its success.Maximising the benefits of complex integrated information systems such as enterprise resource planning systems (ERPS) is signifi cant due to involvement of huge amount of money and time.Despite the increasing number of research on ERPS and management accounting, investigation of these two domains from the fit perspective is limited.Many studies investigating the fi t of specifi c information systems at the individual level have adopted task-technology fit (TTF) as their base.This paper discusses the adoption of TTF in a study to investigate the specific fit between ERPS and management accounting practices.Relevant literature was reviewed to develop a specific framework for the study.The framework is a combination of two separate diagrams depicting two separate groups of testing.The framework consists of adaptation, integration, computer self-efficacy, user participation, ERPS-MAP Fit, and user satisfaction.Hypotheses and implications of this study are also discussed

An overview on phytochemical, anti-inflammatory and anti-bacterial activity of basella alba leaves extract

Inflammation is the complex biological response of vascular tissue to harmful stimuli such as pathogens, damaged cells, or irritants. In the present investigation an attempt was made to screen the anti-inflammatory activity of Basellaalba leaf. From this study, it can be concluded that, Basellaalba possesses a good anti-inflammatory activity. In the cotton pellet induced inflammation and In the carrageenan induced inflammation the animals treated with the plant extract have been shown a significant activity at 500 mg/kg dose (p<0.001) which was comparable with the standard drug. In view of the percentage inhibition also the plant was studied, in which the plant extract was found effective. The antibacterial activity was carried out using different dilutions of methanolic extract against gram positive strains (Staphylococcus aureus, Micrococcus luteus, Bacillus subtilus) and gram negative ones (Pseudomonas aeruginosa) by the cup-plate assay method and minimum inhibitory concentrations (MICs). The different concentrations of extract showed moderate activity against Pseudomonas aeruginosa, Bacillus subtiliswhile weak response against Staphylococcus aureus, Micrococcus luteus and Escherichiacoli. The minimum inhibitory concentration of methanolic extract was 6.25μg/ml against Staphylococcus aureus, Micrococcus luteus, Pseudomonas aeruginosa and Bacillussubtilus and 12.5 μg/ml against Escherichia coli. The overall result of this study indicates that the methanolic extract of Basellaalba have interesting anti-inflammatory and antibacterial properties

Dynamic Performance on Multi Storey Structure Due to Ground Borne Vibrations Input from Passing Vehicles

Ground borne vibration from passing vehicles could excite the adjacent ground, hence produces a vibration waves that will propagate through layers of soil towards the foundations of any adjacent building. This vibration could affects the structure of the building at some levels and even the low sensitivity equipment are also could be affected as well. The objectives of this study are to perform the structural response on multi storey building subjected to ground vibrations input and to determine the level of vibration at each floor from road traffic on the observed building. The scopes of the study are focused on the groundborne vibrations induced by the passing vehicles and analyse the data by using dynamic software such as ANSYSv14 and MATLAB. The selected building for this study is the Registrar Office building which is located in Universiti Tun Hussein Onn Malaysia (UTHM). The inputs of the vibration were measured by using Laser Doppler Vibrometer (LDV) equipment. By conducting the field measurement, a real input of ground borne vibration from the loads of vehicle towards any adjacent building can be obtained. Finally, the vibration level from road traffic on office building can be determined using overseas generic criteria guidelines. The vibration level achieved for this building is at above the ISO level, which is suitable for office building and within acceptable limit

[The Relevance of Fatwa on Zakat Distribution as a Social Assurance System for Muslim Communities in Terengganu] Kerelevanan Fatwa Mengenai Pengagihan Zakat Sebagai Suatu Sistem Jaminan Sosial Masyarakat Islam di Terengganu

The zakat institution plays an important role in preaching the rules of conducts and doctrines based on syari’ah for Muslim community lives. Among others, the zakat institution plays a vital role in explaining the community on the zakat management system. This is due to the fact that zakat, when managed wisely will help to eradicate poverty in the Muslim community. Current practise in Terengganu shows that there are a number of illegitimate ‘amil (zakat collectors) whom are not appointed by the government. Thus, this paper emphasises on the relevancy of fatwa in making the payment and management of zakat becomes much more sustainable, and thus making it more justifiable, and beneficial to the social stability among Muslims in Terengganu. The research found out that the fatwa given by the office of the mufti and his committees is very much relevant with the need of the community, which is, that the zakat (almsgiving) properties need to be managed efficiently and distributed equally to the target groups so that the sustainable of the social welfare in Terengganu is well taken care of. &nbsp; Keywords: relevancy, fatwa, zakat distribution, social justifying system, community, Terengganu. &nbsp; &nbsp; Institusi fatwa memainkan peranan yang penting dalam penyebaran maklumat hukum kepada masyarakat Islam agar kehidupan mereka berlandaskan syariah. Antara usaha yang dimainkan oleh institusi fatwa di Terengganu adalah menjelaskan kepada masyarakat berhubung pengurusan sistem pengurusan zakat. Ini kerana zakat merupakan salah satu kaedah yang boleh menyelesaikan bebanan kemiskinan yang melanda masyarakat Islam. Dalam situasi yang ada di Terengganu, pengurusan pembayaran dan agihan zakat ini bukan sahaja dilakukan oleh pihak pemerintah, bahkan terdapat juga segelintir masyarakat yang bertindak seolah-olah sebagai amil meskipun tidak dilantik oleh pihak pemerintah. Justeru artikel ini menumpukan kepada kerelevanan fatwa dalam melestarikan pengurusan pengagihan zakat agar ia dapat diagihkan kepada golongan yang benar-benar memerlukannya sekaligus dapat mewujudkan satu sistem jaminan sosial dalam kalangan masyarakat Islam di Terengganu. Kajian mendapati, fatwa yang dikemukakan oleh mufti dan jawatankuasa fatwa relevan dengan keperluan masyarakat agar harta zakat diurus dengan lebih efisyen dan tersusun serta dapat diagihkan kepada kumpulan sasar sekaligus dapat menjamin kelestarian sistem sosial masyarakat Islam di Terengganu. &nbsp; Kata kunci: Kerelevanan, Fatwa, Pengagihan zakat, Jaminan Sosial, Masyarakat, Terenggan
