Design of an aluminum can crusher / Mohd Zamzuri Zakaria

This thesis is about to design aluminium can crusher for home purpose usage. By referring to the in-vention of aluminium can crusher, there is a fact that cannot be denied that recyclable products such as aluminium cans have become popular in the beverage industry. But, there is a problem when alu-minium cans become too much and when returning to the recycling station, consumers usually send in a bulk and inconvenience condition. Nowadays, the home-based consumer typically enjoys the cans or beverages from a recyclable can but they are not aware about the recycling processes and disposing the empty cans. For some of the consumer, the task of crushing cans for disposal in the recycling bin can be time consuming for them. In order to cope with this problem, the design of this simple and portable can crusher is used to solve this problem. In designing stage, the author used the high technology design software CATIA to design it virtually before fabricate the desired design. Besides that, this device also friendly user because the user did not have to worry about the spaced required and it is easily to carry anywhere. It is only need a space about 300 mm x 200 mm area. The material used to fabricate its prototype is made from aluminium. So the weight of this device is not too heavy to remove and can avoid corrosion. Furthermore, all the parts involved are assembling by using screws to make it easy to resemble and dissemble. Besides that, this device is fully mechanical operated and can be operated in any condition. By the design of this device, it is hoping that the consumer can save their time, money and also can increase their awareness about the environment

Analisis hubungan kredit mikro dan pembangunan sahabat dalam projek ekonomi skim Amanah Ikhtiar Malaysia (AIM)

Most of the past studies on the impact of Amanah Ikhtiar Malaysia (AIM) microcredit scheme have generally concluded that the scheme has been successful in increasing the income and quality of life of the borrowers. However, in these studies income is examined in aggregate, i.e. household income that covers income from the microcredit project activities and also income from other sources. Thus, while there is an increase in income among the borrowers, it is possible that the increase might not come solely from the microcredit project activities. Disaggregating microcredit project activities income from other sources is therefore important. Past studies also failed to explain the mechanisms through which microcredit affects income, directly or indirectly through mediation variables. Furthermore, previous studies seemed to overlook the impact of microcredit on employment opportunities and productivity, which might be significant. Thus, the objectives of this study are to evaluate the impact of microcredit on income of the borrowers from the microcredit project activities, to analyse the mechanisms through which microcredit affects income, i.e. the mediating effect of human capital, social capital and physical capital, to analyse the impact of microcredit on employment opportunities and productivity, and to analyse the impact of microcredit on poverty and income inequality. For this purpose, a total of 495 borrowers who have been involved in non-farm activities and receive AIM’s microcredit scheme were selected for analysis. Multivariate regression, structural equation modelling and Foster Greer Thorbecke index were employed in the analysis. The findings of the study show that microcredit has a significant impact on the income, even when the income was segregated. The results also interestingly reveal that the impact of microcredit on the income via mediating factors which are human capital, social capital and physical capital is indirect. Furthermore, microcredit also provides a significant impact on the employment, productivity, and reduction in poverty and inequality among the borrowers. Thus, with a complete and systematic financing package, the development of participants in the project activities can be strengthened

Dynamorphic legumes

Basically, my approach is rooted from natural form of composition and improvisation. To compose in the medium of the artistic presentation, the works make temporality interactive. It creates a visual display which evolves dynamically over time, instead of a single static frame, or a preset filmic sequence. The works invoke cross-rhythm, the systematic interplay of contrasting rhythmic motions within a single metric scheme. It brings the operation of an artistic form to the context of browsing the scientific world of presentation. The works were presented in adaptive functional aspects that interconnected to the viewer into visual intuitive form which creates patterns of attention that organize our faculties of perception

Prevention of Springback of High Strength Steel Sheet in L-Bending Process

Nowadays steel sheets are widely used in the industry due to the advantages of this materials in offering high strength with light weight. However due to the high tensile strength the manufacturing process need an improvement to overcome the defects occurred in the production. Therefore, a proper method is required in order to prevent the defects. In this study, a dies set with chamfers are developed to substitute the large radius that are used in current bending process. Bending process were conducted for high strength steel sheets with tensile strength of 780 MPa; to test the effectiveness of the developed die. By using this die, the chamfers enable smaller bending radius to substitute the large radius that cause the springback. It was found that the small radius produces by the chamfers are more effective in reducing the springback in L-bending of high strength steel sheets and the high press-speed will also contribute to the reducing of the springback

DEVELOPMENT AND MODELING OF UNMANNED UNDERWATER REMOTELY OPERATED VEHICLE USING SYSTEM IDENTIFICATION FOR DEPTH CONTROL

This paper presents the development and modeling of low cost underwater Remotely Operated Vehicle (ROV) for depth control using system identification technique. The ROV was developed by the Underwater Technology Research Group (UTeRG). For Unmanned Underwater Vehicle (UUV), the most crucial issue is the control system. It is needed for the ROV to perform several underwater applications and tasks. In this project, a prototype of the ROV will be developed first. The ROV will be tested on an open loop system to obtain measured input-output signals. Input and Output signals from the system are recorded and analyzed to infer a model. Then, system identification toolbox in MATLAB will be applied to generate a model of the ROV. The experimental testing of ROV only considered the vertical movement. The modeling obtained will be used to design the a suitable controller for depth control. The purpose of depth control is to ensure the ROV to remain stationary at a desired depth by utilizing the pressure sensor as feedback. The simulation studies have been carried out in order to obtain the controller of the ROV. This method is useful to obtain the model of the ROV to design the best controller for depth control. Conventional controller will be used in order to verify the modeling of ROV and gives acceptable performances of system response

AUTONOMOUS MOBILE ROBOT VISION BASED SYSTEM: HUMAN DETECTION BY COLOR

This project related to develop and implementation of autonomous vision based mobile robot following human based on clothes color. There have two part are involve which is mobile robot platform and classification algorithms by color. The core of the classification of color are comprise into two process; offline and online. An offline process consists of the training of the static image, using deference input sources that depend on the application. An online process consists of the matching process and the result of the clothes color position. Then classification algorithm is applied to find the centroid of the human. This centroid is then compared with the center of the image to get the location of the human with respect to the camera, either at the left or right of the camera. If the human is not in the center of the camera view, then corrective measures is taken so that the human will be in the center of the camera view. Data for the centroid of human is shown through the Graphical User Interface (GUI). One of the unique advantages in this project, the detection of human by color only uses image processing that generated by the algorithms itself without additional sensor like sonar or IF sensor
