Abstract: High Efficiency Particulate Air (HEPA) filter was introduced during the World War II for removing or blocking very small particles (0.3μm particles) or contaminant from entering the air stream into the clean space. A new HEPA filter production line has been developed, however it has no production management system for the new production line. A lean production management system for HEPA production was developed. Value stream mapping tool was applied by analyzing the current state situation and developed the future state improvement. Production flow was designed into five sessions as a batch flow process to improve the productivity in limited space of working environment and manpower. After reducing the wastes identified in current state study, future state development in production line showed 22% improvement compared to current state study.

Abstract: Pole Side Impact Test is one out of three crash tests described by Euro NCAP standard for star rating of a vehicle and is required for assessing the Adult Occupant Protection. In this paper the goal is to determine the crashworthiness of side doors and B pillar in a Pole Side Impact Test based on Euro New Car Assessment Program (Euro-NCAP) using computer and simulation method. In this matter, a vehicle model has been prepared and meshed using Hypermesh and CATIA. The velocity of 29 km/h has been assigned to the vehicle which was on top of a cart while the pole has been assigned as a rigid static object based on Euro NCAP requirements specifically. Results show that different amounts of energy will be absorbed by each part, such as the side doors and the B pillar, and each part has a different effect on the crashworthiness of the vehicle in a Pole Side Impact Test. It can be concluded that to increase the amount of absorbed energy in a Pole Side Impact Test, the part which has more influence should be taken into greater consideration.

Abstract: Industrial boiler systems are used in manufacturing plant to generate steam for the purpose of production. The current boiler feed exhibits the feedwater chemical parameters that are not consistent with the acceptable water chemistry limits. Around 60% of damages of power plant equipment occur due to deviation from the normal water chemistry. The Six Sigma DMAIC method was used to investigate and prioritize the main issues revolving around these parameters-namely Define-Measure-Analyze-Improve-Control. Based on this case study of the plant, it was found that the leading issues are that there is insufficient pretreatment to remove silica. It was found that there has been significant improvement to water quality to almost all the investigated parameters namely the Silica content, Hardness content and P-alkalinity in the water. The results of this study have proven that Six Sigma is useful in creating sustainable improvement in process in an organization.

Abstract: To assess a car under the Euro New Car Assessment Program (Euro-NCAP), Adult Occupant Protection is one out of three parameters which need to be calculated with a weight factor of 50% while the other parameters, Child Occupant Protection and Pedestrian Occupant Protection, have a weight factor of 20%. The Pole Side Impact Test, beside two other tests, Side & Front Impact, is also required to calculate the Adult Occupant Protection. It shows how important the Pole Side Impact Test is and what an effective role it has in the car rating assessment. In this paper, the objective is to evaluate the effect of thickness on the energy absorbed by the side doors and the B pillar and its crashworthiness in a Pole Side Impact Test based on the Euro NCAP. In this matter, a vehicle model has been designed and prepared using CATIA and meshed using Hypermesh. Five thicknesses have been chosen including 0.6 mm, 1 mm, 1.2 mm, 1.4 mm and the original thickness of the side doors, 0.75 mm. The simulations have been repeated, using LS DYNA solver, assigning each of five thicknesses to the side doors and the B pillar of the vehicle. Initial conditions defined by the Euro NCAP, including velocity and directions, have been applied to the model. A total of 5 simulations have been conducted. The results showed that changing the thickness of the side doors and the B pillar does not necessarily have a direct influence on energy absorbed. The conclusion is that there are different proper thicknesses for each part which will result in optimized energy absorption.

Abstract: The demand for energy in continues to grow. This projected growth in demand has spurned several initiatives aimed at forestalling potential shortages. The focus is on influencing the energy consumption patterns in industry especially during peak demand times when energy supply systems are strained. Moreover, the modern society has become more sensitive to the impact on the environment. More consumers are aware today of the need to conserve energy. A typical platform will enable industry to reduce electricity usage. The ability to manage energy usage more effectively saves businesses. To ensure the provision of adequate, secure and cost-effective energy supplies, resources using the latest cost options are being utilized. To promote the efficient utilization of energy and discourage wasteful and non-productive patterns of energy consumption, the energy policy's approach is to rely heavily on industry to exercise efficiency in energy conversion, utilization and consumption through the implementation of awareness programs. This research will encourage engineers in industry to evaluate, investigate, discover and discuss the various opportunities available to manage energy in industry utilizing a well-structured and engineered methodology and to consider energy management initiatives seriously.

Abstract: The development and application of Titanium Aluminium Nitrate (TiAlN) coatings for cutting tools has led to dramatic tool life extension and the realisation of high speed machining for hardened materials. This results in longer tool life and makes it possible to employ higher cutting speeds and feed rates. In this study, a series of different TiAlN based coatings on micro grains solid carbides were tested on H13 Tool Steel. These advanced coatings are commercially available by coating manufacturer which are trade marks of Balzers UK. The aim of this experiment was to investigate the performance of micro tools coated with these coatings and compare with uncoated tools. The results will be used to determine whether coatings for micro tools will have any impact on the performance of the tools such as reducing cutting forces or improving machining quality. This will be achieved by means of analysing the cutting force data and 3-D surface roughness respectively. Result obtained shows that different coating had different performance, hence can be applied to specifically targeted machining operation. The results also highlight some of the differences in wear mechanism of micro tools.

Abstract: The Bees Algorithm, a heuristic optimisation procedure that mimics bees foraging behaviour, is becoming more popular among swarm intelligence researchers. The algorithm involves neighbourhood and global search and is able to find promising solutions to complex multimodal optimisation problems. The purpose of neighbourhood search is to intensify the search effort around promising solutions, while global search is to enable avoidance of local optima. Despite numerous studies aimed at enhancing the Bees Algorithm, there have not been many attempts at studying neighbourhood search. In this work, the combination of adaptive enlargement and reduction of the search neighbourhood is presented. Two engineering design problems with constraints which were the pressure vessel and speed reducer were selected to demonstrate the performance of the modified algorithm. The experimental results obtained showed that this combination is beneficial to the proposed algorithm.

Abstract: Nowadays, the robotic arm is fast becoming the most popular robotic form used in the industry among others. Therefore, the issues regarding remote monitoring and controlling system are very important, which measures different environmental parameters at a distance away from the room and sets various condition for a desired environment through a wireless communication system operated from a central room. Thus, it is crucial to create a programming system which can control the movement of each part of the industrial robot in order to ensure it functions properly. EDARM ED-7100 is one of the simplest models of the robotic arm, which has a manual controller to control the movement of the robotic arm. In order to improve this control system, a new controller system was redesigned in this work by using Zigbee. It is a communication protocol for safety and economic data communication in an industrial field, where the wired communication is either expensive or difficult under physical and experimental conditions, such as the worker cannot recognize the error through the manufacturing process. Hence, this paper introduced a system that used microcontroller (AT89S52) with wireless devices (Zigbee) and sensors to control the robotic hand (EDARM ED-7100) and to monitor the information regarding the robot's parameter using WiFi technology. A mathematical model was derived through an empirical method to specify the robot's configuration changes. In this work, the ability of controlling system had increased, as well as hardware, while the necessities of other similar equipment for data communication were minimized. In addition, it presents the comparison of two controlling systems: using the Zigbee and without using it. Based from the experiment it can be safely concluded that the robotic arm's movement had followed a linear function.
