AbstractThis paper identifies weaknesses in the ergonomics and design advancements of household furniture. This paper suggests recommendations to enhance the satisfaction and support of ergonomic furniture. Furniture and interior wares are the chosen products of interest, and are specifically emphasised in the context of home living. This paper includes an ergonomics focus on the engineering and industrial design of household furniture, but does not include an analysis of biomechanics, physiology and anthropometry. Based on evaluations of patents from 1980 to 2013, this paper suggests that a user-centred design would be an ideal choice for designers as it potentially promotes customer satisfaction and simultaneously improves the health and well-being of users. The paper synthesises the consensuses of furniture consumers which include data from trends, demands, complexities and preferences.

Keywords – User-centred design, Ergonomics, Furniture, Design, Modular, Multifunctional, Storage.

Abstract Remote sensing has been studied for a long time to monitor the earth terrain. Remote sensing technology has been used globally in many different fields and one of the most popular area of study that uses remote sensing technology is snow monitoring. In previous researches, remote sensing has been modelled on snow area to study the scattering mechanisms of various scattering processes. In this paper, surface volume second order term that was dropped in previous study is derived, included and studied to observe the improvement in the surface volume backscattering coefficient.  This new model is applied on snow layer above ground and the snow layer is modelled as a volume of ice particles as the Mie scatterers that are closely packed and bounded by irregular boundaries. Various parameters are used to investigate the improvement of adding the new term. Results show improvement in cross-polarized return, for all the range of parameters studied. Comparison is made with the field measurement result from U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) in 1990. Close agreement is shown between developed model and data field backscattering coefficient result.

Keywords – Surface volume scattering, Remote sensing, Theoretical modelling, Backscattering coefficient, Radiative Transfer Equation.

AbstractSoil resistivity is an important parameter for designing electrical earthing system. The measurement of soil resistivity is greatly influenced by moisture content, temperature, porosity, degree of saturation, number of soil layer(s), and frequency of lightning current. Researchers have proposed various methodologies to provide an approximation of soil resistivity using the listed parameters. In order to ease the process of estimating soil resistivity at a particular area, there is a pressing need to devise a simple tool that enables the calculation of soil resistivity in the most accurate manner. As such, this research proposes a reliable tool for quick evaluation of soil resistivity based on various methodologies using Microsoft Excel’s built-in-functions and Visual Basic Application (VBA) Next, the developed tool was validated using two methods, in which the output value of the calculator was compared with data retrieved from IEEE Std 142-2007 and data reported in past studies. The validation results revealed that the developed calculator may serve as a significant application in future due to its time-saving and cost-effective attributes.

Keywords – Soil resistivity, Earthing, Grounding, Electrical safety.

Abstract – Vision based patrol robot has been with great interest nowadays due to its consistency, cost effectiveness and no temperament issue. In recent times, Global positioning system (GPS) has been cooperated with Global Navigation Satellite System (GNSS) to come out with better accuracy quality in positioning, navigation, and timing (PNT) services to locate a device. However, such localization service is yet to reach any indoor facility. For an indoor surveillance vision based patrol robot, such limitation hinders its path planning capabilities that allows the patrol robot to seek for the optimum path to reach the appointed destination and return back to its home position. In this paper, a vision based indoor surveillance patrol robot using sensory manipulation technique is presented and an extended Dijkstra algorithm is proposed for the patrol robot path planning. The design of the patrol robot adopted visual type sensor, range sensors and Inertia Measurement Unit (IMU) system to impulsively update the map’s data in line with the patrol robot’s current path and utilize the path planning features to carry out obstacle avoidance and re-routing process in accordance to the obstacle’s type met by the patrol robot. The result conveyed by such approach certainly managed to complete multiple cycles of testing with positive result.

Keywords – Vision system, Indoor surveillance, Robotics, Surveillance robot, Path planning.

Abstract – This work is aimed to design and analyze the staircase climbing aid, hybrid with the function of walking cane. The tremendous demand for living space increases the essentiality of staircase, corresponding to the escalation of fall injuries. The handrails complemented along with staircase had provided deficient safeguard for staircase user, particularly senior citizen and people with lower limb disability, who need staircase climbing aid to provide extra support during escalating or declining staircase.
