Welding is a universal assembly process, implied with industrial and automation implementations. Such procedure involves heating, melting, and mixture of metal or similar to those of the materials being joined. Conventional welding activity may cause some serious health hazards as a result of exposure to metal fumes and to ultraviolet radiation. Implementation of welding robots is a remedy for such health hazards. Therefore, the utilization of several types of welding robots is a typical practice in automobile industries for welding different parts of cars and nickel-cadmium cells in the production of batteries. The proposed work illustrates such a welding robot with 6 DOF which can easily move inside the cylindrical-shaped workspace. Moreover, by learning the position of the end-effector with inverse kinematics, the angles for each joint can be calculated. Hence, along with forwarding kinematic, the end effector can make a gesture towards the desired position. Furthermore, by utilizing the geometry method, the velocity of each joint can also be determined.

Solar chimney power plant is a sustainable alternative for electricity generation using solar as the source of energy. In general, the main body of a solar chimney plant requires a tall structure which is costly and challenging to construct. Thus, it is important to increase the performance of the solar chimney power plant and have a better energy-cost ratio. This study aims to experimentally investigate the influence of divergent solar chimney as opposed to a cylindrical chimney on solar chimney performance. Three divergent scaled-down solar chimney model at 1-meter, 1.5-meter and 2-meter were fabricated and tested for its performance at various simulated heat loads. The test results were compared with similar heights cylindrical solar chimney. The experiments show that divergent solar chimney increases the theoretical power generation potential and improves the stalk effect and have higher outlet velocity compared to a cylindrical solar chimney. The power potential of the divergent chimney is increased up to 18 times with the maximum theoretical power obtain at 0.183W on the 2-meter divergent chimney. Higher temperature was recorded on the 2-meter divergent chimney outlet at 341.3k compared to 330.4k on the cylindrical chimney indicates better stack effect. The highest average velocities in the divergent and cylindrical chimneys were recorded under the electric heat load of 2 kW at 0.994 m/s and 0.820 m/s respectively in the 1-meter configuration. It is also observed that the air velocity in a shorter divergent chimney is higher than taller divergent chimney models while better compared to all cylindrical height. This study finds that a shorter divergent solar chimney produces greater energy compared to a higher cylindrical solar chimney. Therefore, it is possible to reduce the overall cost of solar chimney by reducing the height of the main structure without sacrificing the performance of the solar chimney.

Water removal from industrial effluent streams, salt cultivation farms, biodiesel conversion process from microalgae, and food drying by using pond evaporation with a higher rate of mass flux can be considered as an economical and energy saving scheme. The objective of this study is to utilize a method of enhancing the pond natural evaporation rate to improve the sustainability of industrial operations. In this study, canopied ventilation technology was employed to enhance the pond evaporation. This technology caused the natural draft enhancement by installing a wire mesh on the chimney. The unit consists of a solar irradiated solid wall chimney installed on the evaporation pan as a means to increase the evaporation rate of existing water body. Experiments were conducted in square pan at the same size as class-A pan in three configurations. The experimental result showed that the evaporation flux from configuration YY (Solar chimney with wire mesh) averaged at 13 per cent more than configuration NN (Open Pond) and at 20 per cent more than configuration YN(Solar chimney without wire mesh). Counter to intuition, for configuration YN the evaporation averaged at 6 per cent lower than the evaporation from the open pond configuration. The pan evaporation flux was found to be predicted satisfactorily by the Rayner evaporation model showing it is able to aggregate reasonably the effect of changing characteristics of the three configurations in terms of net radiation, vapor pressure deficit and natural ventilation draft.

Wind energy is recognised as a potential source for free, clean and inexhaustible energy. Therefore, the diffusion of wind energy technology in the power sector has been growing steadily in the past few decades due to the rising concern in global energy issues. Wind power machines, or commonly known as wind turbines, are still further developing over the years to increase its performance in term of efficiency, cost-effectiveness and reliability in wind energy and wind power application. However, there are challenges in the recent developments and technology trends particularly on introducing Nano technology on wind turbine blade design, offshore deployment and operation. This chapter provides fundamental knowledge of wind turbines operation and the implementation of Nano technology on the design aspects of turbine blades with some factors that could affect the performance of wind turbines. Furthermore, the environmental issues that are affecting the performance of wind turbines are also discussed. The details of this chapter cover the challenges of wind turbine design, followed by the principle of wind turbine design and the environmental issues that affect the aerodynamic efficiency of wind turbines.

Industrial Revolution 4.0 or IR 4.0 is getting the attention of Higher Learning Institutions throughout the world. In the case of Universiti Malaysia Sabah (UMS), “transformation towards University/Industry 4.0” has been identified as one of the nine key result areas (KRAs) in the Strategic Plan 2018-2020. The transformation framework focusses on three areas namely Teaching and Learning 4.0, Smart Eco-UMS 4.0 and Research 4.0. Various initiatives have been planned for each area, some of which are currently being implemented. Previously, under the Strategic Plan 2013-2017, UMS gave great attention on developing and promoting UMS as an eco-campus in line with UMS aspiration to be the reference of eco-campus or green campus in the region. This will be further enhanced under Smart Eco-UMS 4.0 in line with the United Nation sustainable development goals. One of the related initiatives is Smart Energy. Through the initiatives under the UMS Ecocampus Plan 2013-2017, a total reduction of 44.50 % in energy consumption was recorded between 2014-2017 compared to 2013 and with 29 % reduction in carbon footprint from 2014-2017. The commitment towards an ecocampus has significant impacts on lowering energy usage and reducing carbon footprint. We believe that the smart energy initiative will further contribute to another level of energy saving and carbon footprint reduction towards reducing the impacts of climate change.

The rice husk (RH) samples were prepared by pre-carbonization at 800 °C, and then further carbonization at 2500 °C (RH2500), under the presence of Argon gas. The RHs were characterized using Field Emission Scanning Electron Microscopy, Transmission Electron Microscopy, and X-ray Photoelectron Spectroscopy. The RH2500 were then incorporated into paraffin wax with different weight percentage (20, 30, 40 wt.%), and designed into toroidal shape with thickness of 1.0 mm to evaluate their complex permittivity and complex permeability using vector network analyzer. The reflection loss (R.L.) of the samples was calculated according to their measured complex permittivity and permeability. The RH 30 wt.%, with thickness of 1.0 mm showed highest electromagnetic wave absorption performance in contrast to the samples with similar thickness but different weight percentage, with minimum R.L. of ∼-14.04 dB (over 96% absorption) at 10.0 GHz. Furthermore, based on the calculation using transmission line theory, RH 30 wt.% ...
