IDEAL CYCLE THERMODYNAMIC ANALYSIS FOR GAMMA-TYPE STIRLING ENGINE
Full text linkThe first-generation gamma-type Stirling engine prototype, intended for micro combined heat and power applications, was manufactured and tested in 2018. Still, the findings were not promising due to its low performance. The goal of this research is to improve the performance of the gamma-type Stirling engine by using the ideal cycle thermodynamic analysis approach to plan more comprehensively. The research approach employed in this study is an experiment that begins with the design, fabrication, testing, and evaluation of the Stirling engine's components. With air as the working fluid, the second-generation gamma-type Stirling engine was created and tested. The maximal volume of this engine is 0.000201 m3. The heat source employed in the test had an average temperature of 674oC. The results showed that, while not dramatically, the performance engine improved. The value of thermal efficiency, engine speed, and power output all increased. The average thermal efficiency is 24.6%. Meanwhile, the engine speed and power generated averaged 415 rpm and 37.9 W. This increase in performance is a compelling reason to continue to develop the gamma-type Stirling engine in the future
ARTIFICIAL NEURAL NETWORK PREDICTION OF PERFORMANCE CHARACTERISTICS OF BIOFUEL PRODUCED FROM SWEET POTATOE (IPOMOEA BATATA)
Full text linkFossil fuel depletion and the harm it causes to the environment has led to the development of alternative fuels. In this research, biofuel (ethanol) was produced and characterized from sweat potatoes. Blends of premium motor spirit with 0% (E0), 2% (E2), 4% (E4), and 10% (E10) of the produced biofuel at various percentages were separately used to power a four-stroke, single-cylinder SI engine on an engine test bed, and data of the engine performance - brake power, brake torque, brake mean effective pressure (BMEP), and the exhaust gas temperature reported in each test. The results of the physicochemical analysis revealed that the physical state of the biofuel is colorless, the viscosity at 300C, density, calorific value, and pH level are 0.9834 mPa.s, 0.85 g/cm3,19 kJ/kg, and 1.82, respectively. It was observed that an increase in ethanol in the blend increases the performance of the engine, although the BMEP at E0 gave the highest value of 0.3 bar compared to other blends. An artificial neural network (ANN) model for predicting engine performance characteristics was developed, trained, validated, and tested using the reported data. The result of the ANN model revealed that the Levenberg-Marquardt training algorithm (LMTA) with 10 hidden layer neurons offers the best fit for the features for both training, validation, testing, and overall. With the R for training equal 1, validation equal to 0.99468, testing equal to 0.90103, and overall R equal to 0.93842 as compared to the rest in terms of the number of neurons and training algorithms.
Inverse Kinematics Solution for a 6-Degree-of-Freedom Robotic Manipulator Based on FABRIK
No full textThis paper aims to present a novel algorithm to solve the inverse kinematics (IK) problem of a 6 Degree-of-Freedom (DOF) industrial robotic manipulator based on FABRIK (Forward And Backward Reaching Inverse Kinematics). The algorithm calculates and locates the joint position for every joint of the robotic manipulator in Cartesian space to bring the end-effector to the desired target position. Based on the obtained joint positions, the rotational angle for each joint is then calculated to complete the IK solutions. The algorithm is tested for its feasibility and accuracy in MATLAB Robotic Toolbox. The results show that with an average of 13 iterations of computing, the joint positions are obtained with an average error of 0.001256 mm in Cartesian space. The algorithm presented in this paper yields high accuracy with fewer iterations of computing thus offering a new way to solve the IK problem of industrial robotic manipulators

The Conceptualisation of Strategic Talent Management for Oil and Gas Companies in the UAE
Full text linkIssues concerning the workforce have been a concern in the Oil & Gas sector, in which the UAE is one of the leading global players. Most local companies heavily depend on foreign experts' knowledge and skills for their competitive advantage. In this case, job roles localisation (Emiratization) has become imperative, and efforts need to be made to lure the local workforce to be part of the local companies. Therefore, there is a need to propose a Strategic Talent Management (STM) so that the local employees can contribute productively to the country's economic growth. This study aims to address the issues of the shortage of the skilled domestic workforce by proposing an STM practice to enhance job performance among local employees in Oil & Gas companies of the UAE. In the initial investigation stage, this paper presents the conceptualisation of strategic talent management and its relationship to job performance. Drawn from the analysis of the existing literature, dimensions of strategic talent management that have a relationship with job performance have been identified, namely, career development, talent attraction and selection, talent acquisition, talent recruitment and mentoring and coaching. The conceptualisation of strategic talent management will be used as the construct for further investigation of the role of strategic talent management that can enhance the job performance of the local employees in the oil and gas companies in the UAE
