In this paper, the generation of vertical jumping motion for tripod hopping robot through reference height control system method in order to converge the differences of reference height for each leg of tripod hopping robot is discussed. The proposed control system is designed using MATLAB/ Simulink which is consisted of maximum height detector, PI controller system in the system of Central Pattern Generator (CPG). By using the approached method, tripod hopping robot can maintain the hopping motion and control the jumping height to achieve the reference height. As the result, we evaluate the effectiveness of CPG networks to keep the stability of tripod hopping robot besides of confirm the validity of using reference height control system to generate moving capability at different reference height.

Two dimensional human body pose modelling system detects the human body parts, estimates their posture and then models them in an image plane using specified shape. In this paper, two windowing techniques are presented and then compared for the human head and torso pose modelling. The first technique, namely Windowing technique I estimates the torso followed by the head of the human. In this technique, the size of the head and torso are manually computed and then the position of the targeted parts is determined. The second technique, namely Windowing technique II, estimates the head followed by the torso of the human. The size and the position of the targeted parts are determined automatically with the implementation of distant transform and several assumptions on human body size and position. The windowing techniques only requires silhouette image as input image. In experimentation, the size and the position of each body part are evaluated from 100 images in indoor environment. From the overall results, the Windowing technique II performs better in terms of correct size and position estimation.

On March 11th 2011, the whole world was taken aback by another tragic experience of Tsunami triggered by a magnitude 9.8 earthquake in Japan. Just few days after that, on March 25th 2011, another earthquake of magnitude 6.8 hit Myanmar deaths and destructions. Despite the loss incurred on properties and human being, available data show that relatively few numbers of animals died during most natural disasters. Prior to the occurrence of these disasters, available reports shows that animals do migrate to higher level or leave the areas en masse ahead of the event. Other related account show that animal sometimes behaves in unusual ways prior to the occurrence of these natural disasters. These overwhelming evidences point to the fact that animals might have the ability to sense impending natural disaster precursor signals ahead of time. This paper discusses the preliminary results obtained from the use of support vector machine (SVM) and Mel-frequency cepstral coefficients (MFCC) in the development of animal sound activity detection (ASAD) which is an integral part in the development of earthquake and natural disaster prediction using unusual animal behavior. The use of MFCC has been proposed for the features extraction stage while SVM has been proposed for classification of the extracted features. Preliminary results obtained shows that the MFCC and SVM can be used for features extraction and features classification respectively.

Multicasting communication serves as one critical operation to support many applications of Mobile Ad hoc networks (MANETs) that achieve group communication rather than pairs of individuals. Multicast routing protocols becomes increasingly important in MANETs because they effectively coordinate a set of nodes. Also, it provides efficient routing for multimedia applications such as video conferences, military and rescue operations. Such applications are highly demand for Quality of Service (QoS), which makes an efficient QoS multicast routing protocols is very important. In this paper, we propose a model that searches for QoS paths from a single source to a set of destinations. The physical area is partitioned into equal size hexagonal cells and a leader and backup leader nodes is elected to maintain up-to-date information about the network topology. Efficient routing is performed based on nodes positions to deliver data packets to all the receivers. The simulation results show that, comparing with the well-known multicast protocol ODMRP (Demand Multicast Routing Protocol), PBQMRP achieves less packet drop ratio with significant reduction in control overhead.

Hand grip strength plays a vital role in performing basic daily tasks such as holding an object. These tasks require a lot of effort from the muscles in the forearm. In this paper, we study the relationship between the muscular effort of the flexor muscles in the forearm and hand grip strength. In order to do that, an electronic circuit was constructed to amplify and filter the electromyogram (EMG) signals measured from the Flexor Digitorum Superficialis (FDS) muscle. The EMG signals measured from the FDS are used to study the relationship between muscular effort of the flexor muscles in the forearm and hand grip strength. EMG signals were measured from the subject while he applied minimum, intermediate and maximum hand grips on a hand gripper. The results show that EMG frequency from the FDS increase with increased hand grip strength. This information relating EMG from flexor muscles to hand grip strength is useful to be used in hand rehabilitation devices to estimate suitable resistance to be provided to patients during rehabilitation routines. Each stage of the circuit development is described in detail so that this experiment can be easily reproduced by others.

Food security can be assured by improving on post harvest storage methods. Food stored under improper storage conditions are prone to increased respiration and transpiration processes which often result in depletion and weight loss of edible material. Storage temperature and relative humidity are major factors that ultimately determine product quality and quantity. This paper presents a survey on methods of post harvest storage systems. The indigenous methods of tropical food storage common to the West African region are discussed. The attendant problems associated with these methods are highlighted. Intelligent control methods are also discussed. A novel intelligent controller is proposed to sustain product quality and quantity by optimizing the storage process.

Unicycle mobile robot main advantages over multi-wheeled mobile robot are higher degree of mobility and less space as it only has one wheel to move. The system developed consists of two parts which are the lower and the upper parts. The lower part is composed of a wheel which is moving back and forth to stabilize the pitch angle. Meanwhile, the upper part consists of a reaction disc and the main frame that functions to stabilize the roll angle of the unicycle system. The dynamic model of the unicycle mobile robot is developed using Lagrangian method and verified through simulation using MATLAB software. The results show that the dynamic model developed can be used to design a model-based controller.

This paper discussed about the implementation of Linear Quadratic Regulator (LQR) on a two-wheeled wheelchair model. The state space model of the two-wheeled wheelchair that mimics double inverted pendulum has been obtained from the linearized mathematical equations of the model. The equations of motions, which are very complex, are derived from the wheels, Link1 and Link2. The goal is to have both links of the two-wheeled wheelchair to be at the upright position. To fulfill the goal, Link1 is to be lifted up from its initial position to zero degree upright position while maintaining Link2 at the upright position. This research is aimed to help disabled people who are using the wheelchair as the main transport for mobility but cannot stand on his own due to permanent injuries on the extremities. The scenario requires a suitable control strategy for the good system performance. Results show that LQR provides good response with the linearized differential equations.

The empirical propagation path loss models have important influence in mobile communication systems design. They become important tools in both research and industrial communities owing to their speed of implementation and their limited dependence on detailed knowledge of the terrain. The mobile services are increasing rapidly and hence the mobile stations are required to design with best quality of service. Path loss models are considered frequently to estimate power budgets and cell coverages. Four empirical models namely, the Lee model, the Stanford University Interim (SUI) model, the COST-231 Hata model and Egli model have been investigated in this work. The measurements were carried out at University Putra Malaysia (UPM) campus and Gombak area. The measured data is used to validate the applicability of the four models mentioned previously in suburban environments. The results show that Egli model, COST-231 Hata model and SUI model over-predict the path loss in all coverage areas. The Lee model shows the best performance to the measured path loss.

The viscosity of Magnetorheological (MR) fluids changes dramatically in the presence of an electric or magnetic field, leading to their being referred to as ‘smart fluids’. These fluids have important applications in the field of damping systems. The MR damper parameters are different for different application and there always exist a trade-off. The optimal values of the parameters are important in the design of MR damper for a particular application. Dynamic range is one of the key parameters of the MR fluid damper. This study presents the mathematical derivation of optimal yield stress and shear force to determine the optimal dynamic range of an MR fluid damper.
