Abstract
Deep underground infrastructure is booming technology in developing countries, and these construction techniques are mostly used in developed countries at present. Pile foundation among many types of deep structures, it is significantly researched and built to sustain and transfer loads from superstructures to deep soil, in either case, the load from the superstructure is very high or the soil at shallow depth is too weak. Piles are subjected to axial, horizontal, momentary, and combined loading systems as a single pile or pile group system connected to the reinforced pile cap on top of the pile to share or transfer loads through the wall and tip to the surrounding soil. Along with elastic solid pile-pile cap characteristics of materials, a limited number of numerical and analytical studies are published even merely on a homogeneous soil placement of the pile cap model. However, The soil’s natural deposit at a significant site may not always be found homogeneous on which pile-caps and piles are placed. To fill the gap of an intricated multi-physics soil-structure interaction problems, successive analysis is incurred to be proliferated. The study presented a numerical analysis of the influence of the pile cap on the single laterally loaded pile, while the embedding of the pile cap varied on the layered soil profile. The standard linear static numerical analysis software ABAQUS was used to model 3D pile cap-pile and layered soil with subjected lateral load and relevant boundary conditions. The result of the analysis was plotted varying the embedding of the pile cap on clay overlaid sand and sand overlaid clay interchangeably taking into consideration other influencing parameters (pile capsize and vertical load). The increase in pile cap embedment on clay overlaid sand slightly increases the lateral resistance of the pile cap for the first few increments and small non-linear variation for further embedding from the analysis has resulted. However, the performance of the pile cap for lateral load resistance was significantly increased as the depth of embedding of the pile cap is increased on sand overlaid clay. Besides, the size of the pile cap has a direct proportion for lateral resistance, and the vertical load exerted on a pile cap has not had a significant influence. The study comprehensively emphasized the interaction of piles with simple soil physics problems, but multi-soil physics problems with pile interaction should be analyzed for future study.

Abstract
Fatty acid methyl ester (FAME) or biodiesel is alternative source for diesel fuel due to its renewability and environmentally friendly nature. In this study, mixed oxides catalysts of Cr-Ti were synthesized by using sol-gel method and used in transesterification of cooking palm oil (CPO) in a batch process to produce FAME. The effects of metal ratio and aging time were studied. The metal ratio Cr:Ti of 1:1, 1:2, 2:1, 0:1 and 1:0 and aging time between 1 day and 5 days contributed effects on the FAME density obtained from the reaction. The catalyst characteristics in term of surface area, pore size, pore volume and thermal stability were also affected by the various metal ratio and aging time during catalyst synthesis. The results show that Cr-Ti catalyst prepared at 2:1 metal ratio and 5 days aging time exhibit FAME density of 854 kg/m3, which is within the value range of biodiesel fuel property. The catalyst has surface area of 45.88 m2/g, pore size of 190.52 Â and pore volume of 0.1984 cm3/g sufficient to promote efficient heterogenous catalytic activity and has good thermal stability. Thus, Cr-Ti mixed oxides has potential as heterogeneous catalyst to produce FAME from the transesterification of CPO.

Abstract
This study explains the added value of the North Sumatra Langkat limestone and its derivative products. Limestone is classified as high calcium, characterized by its high calcium oxide (CaO) content of 38.39% -55.84%, its physical characteristics show dark gray color, dominant calcite, smooth, hard and fossilized texture. So far, the use is in the form of chunks, especially as a raw material for building which gives a low value to the limestone. The 3 limestone samples SK5, SK7 and SK8 were calcined to obtain quicklime and hydrated lime products with different temperatures of 900°C-1100°C. Limestone SK7 and SK8 CaO content increased 59.7% and 66.08% respectively and were light white compared to SK5 55.8% and colored brownish gray. To produce hydrated lime, it is done by adding / soaking with water (H2O) to the quicklime to produce a heat rate of hydration (slaked). SK8 limestone shows an optimum temperature increase of 74.6°C for 75 seconds compared to SK7 and SK5 limestone 50.2°C and 48°C respectively at 900°C combustion temperature. The heat transper occurs on the outer side of the limestone, then spreads to the limestone body. The difference in hydrated heat in the limestone is due to the presence of mineral impurities and non-uniform grain size so that the heat obtained is not perfectly distributed. The impurities such as SiO2, Fe2O3, Al2O3 and MgO contribute to the product quicklime and reactivity of these samples. Besides the quicklime and hydrated lime products, the added value of Batumilmil limestone is derived by making ground calcium carbonate (GCC). The GCC product is fine mesh size of 60 mesh - 400 mesh ultrafine, with high calcium quality and bright / bright color. The increase in added value added from limestone products contributes to the selling value and various applications in the industrial sector.

Abstract
This study aimed to examine the effects of unilateral versus bilateral resistance training and bilateral deficit on unilateral and bilateral strength adaptation among trained men. Thirty recreationally active, resistance trained men were recruited and were divided into three groups; i) unilateral (n=10), ii) bilateral (n=10) and iii) control (n=10). Chest press and biceps curl strength tests were conducted unilaterally and bilaterally before and after six weeks of training intervention. Unilateral bicep curl and chest press training was given to the unilateral group while the bilateral group was asked to undergo bilateral bicep curl and chest press training. 1RM bicep curl and chest press tests were measured unilateral and bilateral strength and bilateral deficit before and after the intervention. The intervention period were six weeks. Mixed design (ANOVA) was used to compare strength during pre- and post-test in groups while MANOVA was used to compare the changes in percentage during pre and post-test between groups. Results showed a significant difference in the test of unilateral strength within groups. Both unilateral and bilateral training groups managed to improve both unilateral and bilateral strength significantly in both exercises but there was a decrease in unilateral and bilateral strength within control group. On the other hand, all the three groups showed no bilateral deficit for bicep curl and chest press test. The findings also revealed that there was a significant difference in the percentage changes between groups. The unilateral group showed a greater change in percentage the in unilateral strength compared to the control group but no significant difference with the bilateral group. While, the bilateral group showed a greater percentage change in bilateral strength compared with the unilateral and control group. In conclusion, this study showed that both of these unilateral and bilateral exercises can increase muscle strength in trained men. However, the unilateral and bilateral strength adaptation is specific to the training performed especially for multi-joint and complex exercise.

Abstract
There are various types of pulse oximeters (POs) including ‘reflectance POs’, which can be used on more sites like the forehead, chest or cheeks and work the same way as ‘transmission POs’ which is the most commonly used device for the continuous measurement of % blood oxygen saturation and pulse/heart rate. This paper describe the design and development of a low cost pulse oximeter (PO) specifically focused on the use of ‘Reflectance Photo-Plethysmo-Graphy’ (RPPG) technology, and compare with commonly used pulse oximeter devices at the East Lancashire Hospitals. The design arrangement involved the use of an Arduino Mega 2560 Circuit Board as microcontroller, Pulse Sensor, Light Emitting Diodes (LEDs) and Liquid Crystal Display (LCD), which allowed subsidising to make a functional device for accurate readings of Heart Rate (HR) in beats per minute (BPM) and % Blood Oxygen Saturation (SpO2). RPPG technique was successfully implemented within the design and development of the PO prototype, contrasting against the more conventional method of transmission pulse oximetry for obtaining HR and SpO2 values. It is concluded that the RPPG pulse oximeter is a more cost effective method of operation with comparable results.

Published: March 2021

Abstract
Front strut bar is an automotive part commonly used for McPherson suspension system to minimize load on the strut tower by tying both left and right strut with a single bar. By distributing the force acting on a single strut to both strut tower, the strut bar minimizes the chassis flex which improves ride and handling especially during cornering. Therefore, strut bar should be stiffer but lighter at the same time to reduce vehicle weight towards fuel efficiency and lower carbon emission. This research attempts to design a lightweight carbon fiber reinforced polymer strut bar to replace conventional steel strut bar with equivalent stiffness. For validation, a steel strut bar model is analyzed by conducting experimental modal analysis to determine their natural frequencies and the corresponding mode shapes. These results were compared to simulation results. Later, the dynamic behavior of CFRP and the equivalent mode shapes were analyzed and correlated with static loading test results. Combination of different ply orientation and stack sequence results in the design of an optimized carbon fiber strut bar achieved 48% reduction in weight, up to 40% higher natural frequency while improving or preserving the static and dynamic performances compared to the steel strut bar.

The thermal distributions of environmental parameters, which were air velocity, air temperature, radiant temperature, inside an office room with air-conditioning system were simulated. The design of experimental study was utilised through the controlled conditions based on the real laboratory studies and real case studies which were later on utilised as the external validity of the field studies. The model of the office environment has been built in the ANSYS Engineering simulation software. The thermal distributions, spatial profiles of PMV are obtained to illustrate thermal conditions intuitively. The distribution of PMV indicated that operative temperature at the 23 °C shows that the PMV is at the level of comfort. Meanwhile the value of PMV for the operative temperature at 23 °C is at 0.79 near the skin of manikin. The research outputs provide useful information for engineers especially in designing air-conditioning system in order to design and build a comfortable indoor environment climate especially in the office environment.

Abstract
The shielding efficiency of coaxial cable is characterized by its anti-interference ability in electromagnetic environment. The testing methods include three-axis method, GTEM chamber method, line injection method, power absorption clamp method, reverberation chamber method and so on. In practical application, it is found that the shielding performance of the cable under high altitude electromagnetic pulse (HEMP) does not accord with the shielding efficiency measured by the cable. While a typical multi-layer shielded cable is selected as the test object, a test method is designed and tested under electromagnetic simulator, and then the test results are verified and extended by CST simulation. Finally, the reason of this phenomenon is analysed theoretically, which has important reference significance for the prediction and testing of shielding efficiency of cable in HEMP environment.
