This paper presents a model for design and analysis of thin cantilever plate for flutter based micro generators. The analytical model formulates the flow induced response on the cantilever plates at various parameters and determines the frequency of flutter which is crucial in designing and selecting proper geometry for a flutter based micro generator. The model makes use of a novel method to solve flutter frequency by equating two different formulations of lift and moment force induced in the structure during the flow. The frequency analysis conducted in this study shows that the thin cantilever plate’s flutter frequency reduces with increase in its width and varies minimal to change in length.

The Global Automotive Policy (GAP) objective is the development of advanced automotive technologies related to MobilityasaService, Next Generation Vehicle (NxGV) and Industrial Revolution (IR) 4.0. NxGVs can be electric vehicles (EV) and electrical conditional automation vehicles (EAV). Technologies prototyping for NxGV with increasing levels of automation will be the clear mobility of the future. The NxGV transmission could be either an automatic transmission (AT) or a continuously variable transmission (CVT). However, the automatic gearbox and CVT are heavier and require more space, therefore they consume more energy and are difficult to install with an NxGV electric motor. In addition, the singlespeed gearbox (SSGB) is lighter, but not suitable for delivering enough torque in climbing. Therefore, developing a compact and automatic energy efficient transmission is a key technology challenge for NxGV. The purpose of this study is to present a prototype of a compact and lightweight artificial adaptive fuzzy interference system (AAFIS) electromagnetic two speed gearbox (AEM2SGB) for the NxGV in accordance with the GAP 2020 and IR4.0 forward policy. Research Management Centre (RMC), International Islamic University Malaysia with a research grant “Research Incentive Flagship Grant (Ref. RIF190320032), financed this project. The AEM2SGB was developed for a 3.0 kN IIUM test car using equivalent road loads and found the AEM2SGB's shift times in first gear to be 1.5 seconds with a higher torque of 530 Nm and 1.8 seconds in second gear for 110 km / h. The highend AEM2SGB is therefore expected to reduce the weight of the NxGV drivetrain by about 46% and improve the performance of the NxGV by reducing power consumption by about 30% and extending the range by 15%. AAFIS capabilities for successful management of AEM2SGB can operate in NxGV automatic mode

Reducing the weight of automobile helps improve energy consumption and reduce greenhouse gas (GHG) emission. Multifunctional components of the automobile are one of the best options which could be useful to make the vehicle lighter and functional as an energy storage and source. Polymer Nano-filler composites signify as the most encouraging and promising family of materials for the solid electrolyte of vehicle energy technology due to its wide band-gap and higher charge density capacity under an electrical field (electron drift) and thermal effect (diffusion). This paper reviews the prospects of Nano-fillers conductive polymer solid electrolyte sandwiched by carbon fibre (CF) and lithium (Li) plate composite for the EV panel serves as the electric energy storing. The reviewed studies shows that the dielectric sandwiched composite body would save 15% electric vehicle energy (3000 Wh) by cutaway body weight and battery size by 30%, store the vehicle regenerative braking power density about 600-700Wh, save the vehicle passengers’ air-conditioning power density about 5% (1000 Wh) from heat insulation. The characteristics of new technology in terms of energy saving and generation indicates that the 33kWh battery equipped electric vehicle would be able to save 4.7 kWh energy which would enhance the vehicle travelling distance about 25 km and reduce the emission and could cut the cost of battery power pack about USD3500 per vehicle.

Nowadays, the continuously increasing diminution of conventional fossil fuels has increased the interest of the research and development sectors in finding green and renewable supplements. A momentous attention has been given to the production of biogas via the anaerobic digestion of biomass. Biogas major components are methane, carbon dioxide and traces of hydrogen sulfide, ammonia and nitrogen. Hydrogen sulfide and other impurities are usually removed in a process called biogas purification. Biogas upgrading process is the process by which carbon dioxide (composing 40% of the biogas) is removed. In this study chemical absorption process for upgrading biogas was performed using 3 different solvents (sodium hydroxide, monoethanolamine and ammonia). The three different solvents have shown great ability in absorbing carbon dioxide as well as hydrogen sulfide using a lab scale packed column absorber-apparatus. The lab scale apparatus is designed to manipulate the different process parameters of liquid/gas flow ratio, column height and solvent type. Varying the different process parameters a biogas purity up to 93.3% methane content was obtained.

The average PO is then computed at the end of the semester/programme for each student/cohort. Weightages at the course and/or programme level are used to finalize the final POs achievement.

An outcome is not a collection or average of previous learning experiences, but a manifestation of what learners can do once they have had and completed all of those experiences. The previous POs assessment at Kulliyyah of Engineering (KOE), IIUM, by measuring and averaging POs across courses is not supported by the current practice by ABET. PO or student outcomes in ABET terms are statements that describe what students are expected to know and be able to do by the time of graduation. Outcomes are high-quality ‘culminating’ demonstrations of significant learning in experiences, literally at the end or after the end. This paper presents the OBE framework at KOE-IIUM which categorize course into enabling and culminating courses, describes the process of selecting culminating courses from the engineering curriculum and provides a strategic POs evaluation for each culminating courses using rubrics

For the conversion of solar irradiation directly to electricity, Photovoltaic (PV) cells play an excellent role. Absorption of radiation beyond wave length 0.35 – 0.82 µm leads to a rise in temperature and the performance is significantly reduced as a result of temperature rise. Many attempts have been made to maintain the operating temperature of the PV cells as low as possible using both water and air cooling system fitted at the back of the panel. In this project, extensive indoor and outdoor tests have been performed to develop an integrated system to filter component of solar irradiation contributing to a temperature rise of the PV panel. For indoor tests, a Compact Source Iodide (CSI) lamp has been used to conduct experiments under controlled conditions. The outdoor test was conducted under the meteorological conditions of Singapore. The component of interest, which produces electricity, will be delivered to PV cells and, hence, there will no heating effect and performance degradation. A layer of water of about 15 mm can eliminate the components of the radiation not contributing to electricity generation. Also, absorbed radiation at the water filter enables to provide hot water.

The development of commercialized electric vehicles (EVs) has yet to be accelerated due to the lack of electrification. Electric vehicles charged with low-emission electricity are one of the key options to reduce emissions in passenger road transport. The introduction of electric vehicles will inevitably lead to a greater interaction between the mobility and the electricity generation. The electric car penetration reaches higher levels; the electricity demand from electric cars will become a relevant factor in the energy system and impacts the operation of power plants and grid infrastructure. Different smart charging strategies could be considered on the chosen goal of electric vehicle demand management: reducing grid constraints, maximizing utilization of renewable energy production to reduce CO2 emissions or minimizing emission by shifting electricity generation from coal and gasoline power plant to hydropower plant. This paper presents the eco-friendly smart electric vehicle body panel which considered as an energy generator from the solar power and vehicle deceleration and storage them unit discharged to meet the auxiliary power system demand. It would be able to reduce the grid constraints and incremental power plant capacity. The smart body panel is expecting to generate the renewable energy about 3.66 kW from solar power and vehicle deceleration from 125 km/h to 25 km/h and also the save vehicle propelling power about 10% by cutting away the vehicle weight about 15%

Biomethane is a result of the process removing of the CO2 in the biogas to get the high purity of methane content up to 97% using the adsorption process. This technology could be potential to use in the fuel production as nowadays the production of fuel was slowly depleted. Biomethane is one of the sources that closely resembling the natural gas to act as a source of energy to rural areas and has been researched for many years due to their potential as renewable energy for future. There are several methods that have been developed to increase the purity of biomethane such as chemical/physical absorption, water scrubbing, membrane separation and pressure swing adsorption (PSA). The demand of the technologies for biomethane upgrading in industries keeps increasing by year as used as vehicle fuel. The PSA method has been focused in this project. The method was used to increase the content of biomethane to reduce the amount of carbon dioxide in the gases and to eliminate some impurities. The PSA system basically use the application of the absorbent such as activated carbon and molecular sieve at high pressure condition in adsorption column. It is proved that the PSA method is a good method to separate the CO2 from the biogas to get high content of methane (over 90%) using selected adsorbent. By using the upgrading technologies process will give the opportunities to develop high quality production of biomethane with environmentally friendly and lower operational cost.

Biogas upgrading process is usually performed for the removal of impurity gases (mainly carbon dioxide) other than methane from the biogas mixture. Being operated at high pressure and low temperature, both physical and chemical conventional upgrading methods lack energy efficiency. While a high pressure is used in the most common physical process; the high pressurized water scrubbing method, the widely spread chemical method of amine scrubbing is operated at high temperature gradient between the absorption and regeneration steps. In the current study, biogas upgrading using aqueous ammonia is proposed to replace the other conventional methods. An improved process of aqueous ammonia scrubbing operated at ambient or near ambient temperature and pressure is discussed for the purpose of removing carbon dioxide from biogas. A flow diagram for the process was built using the Aspen Hysys software provided by Aspen Tech®. The simulation results have shown that the proposed process, due to the high purity methane produced and being operated at ambient temperature and pressure, has a high potential in replacing the conventional upgrading methods.

In the tropics, air conditioning is essential as the operating daily ambient temperature is high. In Malaysia and Singapore, most of the houses and apartments are air conditioned, at least one room. Every kW of electricity consumed by the air conditioner, about 4 kW is thrown into the atmosphere. Energy is available at the inlet to the condenser at about 85oC and can be utilized for useful purposes. Here, waste heat from air conditioners is utilized for water heating and drying purposes. A water condenser fitted at the exit of compressor absorbs most of the superheat and latent heat. Even a 60% recovery of this waste energy can heat 200 litres of water to 60oC within about three hours. A dryer connected at the exit of air condenser is fitted with filter to supply clean hot air to the dryer. The system reduces global warming and the payback period is less than two years.

Photovoltaic systems have become recently the most attractive and promising technology compared with other solar energy conversion devices. Solar energy reaches the earth’s surface in wavelengths between 0.300 and 2.50 μm. Silicon based photovoltaic systems convert only the wavelength between 0.35 to 0.82 μm of solar energy to electricity. The rest of incident solar radiation will be converted to heat, which will increase the operating temperature of the device and decrease the output power and efficiency. Maintaining the operating temperature of the PV systems at low and desired value was the main emphasis of different researches through the last decades. In this research, a special transparent glass cover (STGC) was used in order to cool down the photovoltaic module and, therefore, increase the output power and the efficiency of the module. The result showed that STGC led to 2.75% improvement in open circuit voltage, 9.6% increase in short circuit current, 26.4% increase in the output power, and 3% increase in the efficiency of the module.

Research to improve flat plate solar collector performance such as design and material used continuously developed. This paper's objective is to analyze the performance of the thermal cell absorber attached to a flat plate absorber collector (FPBTCA) through a low thickness design.

Methane is similar in energy content compared to gasoline. Therefore, methane is suitable to be paired or replaced with existing Internal Combustion (IC) engine with slight modification. When compared with gasoline in terms of RON, methane gas is much higher. Such quality in vital in producing high power and high compression Spark Ignition (SI) of engine. Therefore, exploiting the methane gas characteristic is crucial in developing a greener energy consumption for our substance. Generally, this paper consist of two phases of experiment where first phase will be the compression stage to store biogas in a pressurized state in order to obtain desired energy content, and the second phase which involves the biogas testing in an IC engine. The challenge would be selecting the best IC engine to run on the compressed biogas adequately. This report will focus more on the engine performance in terms of brake horse power (BHP), efficiency and fuel consumption. Care also be taken to include the...

Comprehensive comparison on quarter-car, half-car and full-car models were conducted to analyze the effect of using semiactive control policies, namely skyhook, groundhook and hybrid controls, in improving ride quality of passenger vehicle. Sprung mass acceleration, suspension deflection and tire deflection responses were analyzed for measurements of ride quality, rattle-space and road holding. Three different analyses were conducted on each model; frequency-domain transfer function analysis, time-domain transient state and steady state analysis. Results shows that hybrid control policy gives significant improvements in most responses while at the same time it does not compromise road holding ability of vehicle. Further quantitative comparison of responses on all three models shows that quarter-car model is unable to accurately represent responses in full-car model. Half-car model gives reasonable representation of full-car model in some states. RMS analysis conducted on a H-car 2-D...

Heavy electrical load in a vehicle will consume more electrical power from the battery. Thus \vilt affect the performance of the vehicle and voltage stabilizer is created to cater this problem. This chapter shows the experimental investigation of the performance and the emission effect the vehicle using aftermarket voltage stabilizers. The experiment is mostly carried out in laboratory and few experiments were carried out by test drive. All data are recorded compared \vith the data found from the MATLAB analysis. Chassis dynamometer test shows on certain value of capacitors it does have an increase of torque and power by 5%. From emission result by using Gas Analyzer, it shO\vs that the voltage stabilizer could reduce some the hazardous gases especially hydrocarbon which contributes to the global warming. consumption from 160 km test drive shows a 5% mileage increase from the ordinary vehical setting. From all experiments conducted, the best capacitor value needed to be equipped ill...

Several types of flat plate solar collectors have been designed and developed with various technical parameters involved in the design. The inappropriate flat plate solar collector parameter design and material chosen will affect its performance. Investigation on the effect of flat plate absorber collector material, glass thickness, air gap distance, thermal cell absorber thickness, and flat plate absorber base collector thickness on the performance of solar thermal collectors was conducted in this work. The experiment was performed using the solar simulator with solar radiation of 450 and 750 W/m2. The flat plate absorber collector materials used in this experiment were stainless steel 304 and aluminum. The glass thickness used in this experiment was 2.0, 3.0, 4.0, 5.0, and 10.0 mm. The air gap between the flat plate absorber and glass used in this experiment was 0, 5.0, 10.0, 20.0, and 30.0 mm. The stainless steel thermal cell absorber thickness applied in this experiment was 0.5,...

Innovations are required for electric vehicles (EVs) to be lighter and more energy efficient due to the range anxiety issue. This article introduces an intelligent control of an organic structure solar supercapacitor (OSSC) for EVs to meet electrical load demands with solar renewable energy. A carbon fibre-reinforced polymer, nano zinc oxide (ZnO), and copper oxide (CuO) fillers have been used in the development of OSSC prototypes. The organic solar cell, electrical circuits, converter, controller, circuit breaker switch, and batteries were all integrated for the modelling of OSSCs. A carbon fibre (CF)-reinforced CuO-doped polymer was utilised to improve the concentration of electrons. The negative electrodes of the CF were strengthened with nano ZnO epoxy to increase the mobility of electrons as an n-type semiconductor (energy band gap 3.2–3.4 eV) and subsequently increased to 3.5 eV by adding 6% π-carbon. The electrodes of the CF were strengthened with epoxy-filled nano-CuO as a p...
