Thermal Imaging is increasingly being used to study heat coming from the body using specialized infrared cameras that measures temperature. The aim of this study was to determine if skin temperature above the muscle was related to EMG signal of the muscle during certain functions. In this study, six subjects carried out arm movements such as wrist flexion-extension, hand close-open and forearm pronation-supination...
The flexion and extension of human muscular doesn't only support the human's motion but it also could help in term of energy harvesting. Motion of the human body is capable to generate electrical energy with the support of suitable harvesting devices. This type of energy is very useful for those do not have access to the electrical power grid for prolonged duration. Biomechanical energy harvesting...
In the recent years, the field of robotics been developed at a very fast pace due to the technology development. Robots been used to perform the tasks that human can and cannot do and this has mad the human life much easier. The most popular robot nowadays is the humanoid robot. Humanoid robot is a robot that been designed to have a similar feature to a human body part such as hand, leg, finger and...
Low back pain is a spinal-related problem mainly caused by degenerative disc disease. Throughout the spine, the lumbar region is the most prone to the disease since it supports the upper torso by transmitting compressive and shearing forces to the lower body during everyday activities. The study focused on the bottom-most L5-S1 segment of the lumbar. The project was conducted by measuring the range...
This paper presents an improved single phase seven-level active rectifier architecture controlled by finite control set model predictive control (FCS-MPC). The FCS-MPC is designed to enable power conversion with a unity power factor and generate seven level voltage waveform at the input. The proposed active rectifier architecture reduces harmonic contents of the rectifier input current by producing...
In this paper, we propose a novel parallel Elliptic-Curve-Cryptography (ECC) point multiplication implementation over binary Galois Field, GF(2m) by exploiting the advantage of concurrent operation in a homogeneous multi-core processor to yield an improved performance. A modified Lopez-Dahab (LD) mix-coordinates point multiplication algorithm is developed that exploits concurrency and enables operation...
This paper presents a new diode free freewheeling and common-mode voltage (CMV) clamping branches for single phase transformerless grid connected photovoltaic (PV) inverter for complete leakage current elimination and low conduction losses. In the past, various isolation techniques have been proposed for leakage current elimination in transformerless PV inverters. However, galvanic isolation only...
A hand home-based rehabilitation system which is interactive, portable and affordable, equipped with the ability in qualitative and quantitative diagnosis on muscle performance and strength is reported in this paper. The therapy system utilizes the concept of game-based therapy which aims to develop interest of patient. The hardware input module has a compact joypad input design with wireless connectivity...
In this paper, the plantar pressure distribution and the center of pressure movement were studied and gait stability of high heels versus normal heels was observed. A group of ten young female participants without any previous lower limbs injuries were asked to wear shoes of different heel heights, namely, 0cm, 2cm and 4cm and walk at a speed of 3km/hr on a treadmill. The pressure that their body...
The field of electrical engineering is now being widely used in vehicle technology. The current demand of high electrical power owing to increase in electrical vehicle and the pressure on automobile markers to reduce emission levels have brought the usage of power converters and electric drives to the frontline in automation and robotic industries. This research aims to discuss the design and control...
Ant colony optimization (ACO) technique is proposed to solve the mobile robot path planning (MRPP) problem. In order to demonstrate the effectiveness of ACO in solving the MRPP problem, several maps of varying complexity used by an earlier researcher is used for evaluation. Each map consists of static obstacles in different arrangements. Besides that, each map has a grid representation with an equal...
In the construction of robot applications, controller is very important in producing good performance the robot system. This paper presents the modeling and simulation of multi fingered robot hand (MFRH) with the conventional and modern controllers where the output responses have been analyzed. A swarm algorithm known as Particle Swarm Optimization (PSO) has been used to find optimum solutions in...
This paper presents harmonics improvement in a DC-DC converter based line frequency inverter for domestic lighting loads. Harmonics problem in power electronics converters is not a new phenomenon as over the decade succeeded in effecting our power output. It is also recognized to be a problem that would destabilize the reliability of power system, to overcome this problem, the design of a suitable...
This paper studies the pressure distribution on the forearm and the hand palm during ambulation with forearm crutches. It also presents the design, modelling and development of a forearm crutch that is capable of eliminating the high pressure induced on patient's palm and forearm areas while gating; preventing other injuries to the nerves and muscles of the mentioned extremities. Eventually, one of...
A model of an anti-collision system for vehicles was designed, in a way that to avoid head-on collisions only. Two small motorized cars were built. Each car consist of Arduino microcontroller, ultrasonic sensor module, RF module and two DC geared motors. Each car is driven by a couple of DC motors from the rear end while the front is only a castor. As a form of differentiation each car was given the...
A buck converter is a dc to dc converter which can be categorized in the DC chopper family. Buck converter is a static device that is mainly used to obtain a variable DC output voltage which is less than the input fixed DC voltage source. Harmonics is the major concern in a Buck converter system. The interference of harmonics signal often results at the input and output of the load side. With the...
In the modern science and information technology everyone wants to attach with latest technology and services. Although visually impaired people do not get proper light from the benefits of technology revolution due to lack of scope. Mongol Dip will give visually impaired population a great opportunity to connect with and contribute to the digital world. In this paper we present software named ‘Mongol...
This paper presents the analysis of various ferroresonance suppression circuits (FSCs) in 132 KV Capacitive Voltage Transformers (CVTs). Simulation studies are conducted on 132 kV Trench CVT using Electro-Magnetic Transients Program (EMTP). In this paper, ferroresonance is initiated in CVT by circuit breaker switching.
