    A green technology of acoustic of fluid-structure interactions become an emerging technology today, a call thermoacoustic heat engine. Thermoacoutics heat engine systems convert the energy on a harvesting from a waste heat energy and convert to an electrical energy. That component of devices a call a hot heat exchangers. This paper study was focused on a new design of thermoacoustics heat exchanger and investigation of its performance in terms of thermal analysis. A conceptual design was produced with three designs of hot heat exchangers, which are wire-type, finger-type and star-type. Commercial code ANSYS-CFX software are used on the evaluation, the heat exchanger’s designs were simulated with two thermal conditions which are steady state and transient heat conduction. Materialselection from copper and aluminium a chosen to look-out the engagement between theoretical and numerical study. There are three inlet temperatures that are assumed will be supplied by constant waste heat which are 200°C, 350°C and 500°C.The star-type design has the highest value of heat conduction through a fin heat conduction with copper as a material which is 32.84W. Star-type hot heat exchanger recorded the fastest time to distribute temperature compared to wiretype and fingertype heat exchanger. Result shown the combination between star-type design and copper material will produce a good agreement to design a hot heat exchanger.

    The purpose of this study is to use water cooler and water heater to improve the convenience of the user so that they can use the water cooler and mobile water heater properly and comfortably. This study focuses on how refrigeration and water heaters use thermoelectric pads as a cooling and heating medium. Peltier works when the voltage is flowing from the power bank. The temperature difference on the surface of the processor allows the heat to occur at a fast rate. Arduino uno is used as a voltage regulator and temperature sensor to improve product performance. concept designs are designed, created and evaluated. The final prototype will include some markers that will be used as temperature readings by cooling and heating. Based on the results shown, the prototype can achieve the desired result with optimized energy consumption. When the temperature supplier produces a good temperature, the amount of water temperature will rise and the heat in the water will reach thermal equilibrium until the cold and hot temperatures reach a better minimum. Therefore, the temperatures in the cold and hot areas are more efficient in achieving thermal equilibrium in rising water.

The objectives of this study to improve the current plant layout by redesigned it with increasing the production efficiency and productivity of the company. To achieve this aim, there are several layouts generated using Systematic Layout Planning (SLP) and Graph-Based Theory (GBT) and the Efficiency Rate (ER) of each layout was calculated. The layout with the highest rate was then selected and validated by using WITNESS software. The result showed that the ER of the selected layout improved from 74.49% to 93.40% and also increased the productivity and reduced the processing time up to 10%. The described case study will show how the efficiency and productivity of a real manufacturing system can be improved by redesign layout.

    A solar car is a lightweight, low power vehicle designed and built with a single purpose in mind–racing with and only drive during the day. It has limited seating (one or two peoples) and usually has very little cargo capacity. However, it offers an excellent opportunity to develop future technologies that can be applied to practical applications. This study will focus on design and analysis solar car chassis part. The primary challenge in developing an effective solar car chassis is to maximize strength and safety while minimizing the weight. Every extra pound requires more energy to move down the road. However, safety is a primary concern and the chassis must meet stringent strength and safety requirements. The purpose of the study is to understand the concept design of solar car chassis in terms of calculation, material selection, chassis style selection and virtual analysis for chassis using CATIA software.

    Water is the most demanding resource in the world especially in the era of the rapid growth of population and development. Therefore, delivering good quality water to consumers is important for their security of lives. Gravitational Filter Based on Origami Concept (G-Filtro) is a water filtration device that will be placed in a water tank at the residential area before people consumed it for everyday used. The specialty of this device, it does not necessarily attach to any power source. The objective of this project is to design and develop 3D G-Filtro using 3D CAD software and CFD analysis is used to determine the efficiency of the G-Filtro by simulating and model the pressure, velocity and streamline. Based on the result, the maximum water velocity for simulation without the filter is 0.266 m/s and the maximum velocity for first and second designed filter are 0.254 m/s and 0.243 m/s respectively. From the CFD simulation, the G-Filtro can remove the contaminants in water tank efficiently. Hence, it is proven that G-Filtro can be added as a new water filtration device.

    In today's world, transportation system has a very vital role to play in day to day life. However, when it comes to take the public transportation especially bus transport, time and patience are of essence. In the other word, many people who use bus transport have experienced time loss because of waiting at the bus stop. In order to overcome this problem, the Malaysia Public Bus Monitoring Real-Time System via GPS and GSM is implemented to help the bus user to track the current location of the bus in the form of latitude and longitude coordinates by using GPS technology. It is to reduce the waiting time of the bus user and enhance the current bus service system to become more effective and efficient. This technology of Global Positioning System and Global System for Mobile communication is used where the GPS module will track on the current position of a particular bus by receiving signal from at least three GPS satellites. The data is then will be send to the microcontroller unit to be processed, control and interpreted. A microcontroller board based on the ATmega328P act as interface between the GPS and GSM Module where it will perform the process to interpret the output and input. As for the GSM Module, it will be used to allow the message to be sent to the user regarding the current bus position. As the outcome, the bus user will receive a text message containing the latitude and longitude coordinate of the current bus position. Results show that the location of the bus can be tracked in the form of latitude and longitude coordinates by using GPS technology. The waiting time of the bus user can be reduced by applying the GSM technology to inform the user vis Short Message Service. The current bus service system can also be enhanced to be more effective and efficient.

    The TiO2-geopolymer paste had been prepared by dry-mixing of the fly ash with various concentration (wt%) of TiO2 nanoparticles (2.5%, 5.0%, 10.0% and 15.0%). Those powder mixtures were then mixed with the alkali activator with the ratio of 2.5 and were cured at room temperature for 28 and 640 days. The phase and chemical bonding analysis revealed that the incorporation of TiO2 nanoparticles did not create any additional phase or functional group, but only physical interaction might have occurred in between the TiO2 and geopolymer matrix. However, the physical properties were depending on the TiO2 nanoparticles content where setting time of the geopolymer can be shortened by the addition of certain amount of TiO2 nanoparticles (up to 5.0 wt%). The water absorption also increased as a function of TiO2 content, due to the formation of the micro cracks as a result from the agglomeration of TiO2 nanoparticles. The compressive strength reaches its maximum value, 85.9 MPa with 5.0 wt% of TiO2 nanoparticles. Beyond 5wt%, the strength decreased almost half of the maximum value, where agglomeration becomes a main factor. While for 640 days of ageing, sample with 15.0 wt% shows triple increment from 30.6 MPa to 95.3 MPa.
