    There are three major phases in completing project named, “Stress Concentration Factors at Two Radial Adjacent Nozzles Header Connections of a Cylindrical Pressure Vessel”. These three phases are; parameters specification, design and Finite Element Analysis (FEA). This report basically will summarize the activities that have been done to complete this project. In parameter specification phase, data acquired to design a two radial adjacent nozzles header connection of cylindrical pressure vessel was extracted from the standard nozzles and piping codes used in the industry. The required data and information for this project also been gathered by using all available resources. In design phase, the author will compiles all data and parameters gained and design a nozzles-pressured vessel configuration which will be the basis for the whole project. Finally, a FEA simulation will be done by using ANSYS to analyze the model and complete these project objectives. The design of nozzles in a pressure vessel is subjected to the internal pressure acting from all direction. But in this study, only the internal pressure effect will be considered. This project objectives are to analysis and investigate the stress concentration factors of two radial adjacent nozzles header connection of cylindrical pressure vessel result that come from internal pressure by using ANSYS and To study the result and effect of different nozzles inner diameter and size and displacement of these two nozzles so that, recommendation can be made to improve the design of two radial adjacent nozzle header connection of cylindrical pressure vessel. From this project, it is decided that stress concentration factor most occur at low value of L/d ratio which the distance between the two nozzle are closer

    This report constitutes of, as the title for this project, Smart Ground Station Antenna for Excellent Quality of Received Data Signal. The objective of this project is to build an intelligent antenna in order to receive with less noise signal transmitted by nano-satellite. It will be a challenging project since the distance of satellite from antenna is quite far with a lot of noise can affect the transmission process. The antenna is a 6 elements Yagi-Uda type with frequency of 434MHz. A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system consisting of an array of a dipole and additional closely coupled parasitic elements (usually a reflector and one or more directors). The dipole in the array is driven, and another element operates as a reflector. Other parasitic elements shorter than the dipole added in front of the dipole and are referred to as directors. The antenna was design using software called QY4. The antenna consists of 4 director elements, 1 driven element and 1 reflector elements. Directional antennas, such as the Yagi-Uda, are also commonly referred to as beam antennas or high-gain antennas. Yagi antenna is chosen because of good range, highly directional and easier to aim than a parabolic dish

    Merged with duplicate record 10026.1/851 on 06.20.2017 by CS (TIS)Over the recent years 'transparency' or better information disclosure has been the buzzword of various corporate governance bodies due to the failures of the system of corporate governance, which arise from an agency relationship. However, there are arguments by 'free market' advocates suggesting that information is voluntarily disclosed. This study discusses and compares the disclosure of information relating to directors' behaviour in the United Kingdom, Canada, the Netherlands, France, Germany and Sweden. These countries were selected because they represent the developed countries with different accounting systems. Furthermore, they are also the board member countries of IASC and OECD. 'Transparency' relating to directors' behaviour for the six countries were measured using disclosure indices, i.e. the disclosure point average for dichotomous, modified dichotomous weighted dichotomous and weighted modified dichotomous indices. These weighted indices were established by analysing survey responses of investment analysts. The results show that there were significant differences in the disclosure of information relating to directors' behaviour among the six countries. There is also a very low level of 'transparency' in all the countries except the United Kingdom. These results suggest that information relating to directors' behaviour is not voluntarily disclosed and therefore regulation is necessary in order for it to be more transparent as suggested by the various corporate governance bodies

    Get PDF
    A polymer is generally manufactured by polycondensation, polymerization or polyaddition, when combined with various agents to enhance or in any way alter the material properties of polymers the result is referred to as a plastic [1,2]. Composite plastics refer to those types of plastics that result from bonding two or more homogeneous materials with different material properties to derive a final product with certain desired material and mechanical properties. Advanced polymer composites are generally understood to be materials consisting of a polymer matrix reinforced with high-strength continuous fibers of a predefined orientation

    An entrepreneur needs to be physically and mentally prepared, with creative thinking skills, risk taker attitudes, as well as being a wise decision maker. Individuals aiming to be successful entrepreneurs need to have adequate entrepreneurial readiness with respect to knowledge, interests, motivation and abilities. The purpose of the research is to measure the level of readiness towards becoming entrepreneurs among participants of the lifelong learning programme in Malaysian community colleges. This research focuses on four elements of readiness comprising knowledge, interest, motivation and ability which were measured using a self-perception questionnaire. The sample for this research consisted of 236 participants from 305 students in the Lifelong Learning (LL) programme for Pastry making at Malaysian community colleges under the Ministry of Education. Data were analysed using mean and Kruskal Wallis test. The data analyses results show that the level of readiness from the aspect of knowledge (M = 3.67, SD = 0.58) is moderate, interest (M = 4.13, SD = 0.55) is high, motivation (M = 4.13, SD = 0.55) is high and ability (M = 3.8852, SD = 0.64) is moderate. No difference was found on entrepreneurial readiness between participants of different age groups indicating that age may not be a contributing factor towards entrepreneurship among pastry making LL programme participants. &nbsp
