Multiscale boundary element method for Laplace equation

In this paper, the multiscale boundary element method is applied to solve the Laplace equation numerically. The new technique is the coupling of the multiscale technique and the boundary element method in order to speed up the computation. A numerical example is given to illustrate the efficiency of the proposed method. The computed numerical solutions by the proposed method will be compared with the solutions obtained by the conventional boundary element method with the help of Fortran compiler. By comparison, results show that the new technique use less iterations to arrive at the solutions

Intelligent glove for suppression of resting tremor in Parkinson’s disease

One of the significant symptoms in Parkinson’s disease is resting tremor. Resting tremor occurs when the muscle is relaxed, causing the limb to shake. Rhythmic muscle movement of the patients commonly happens within the range of 4 Hz to 6 Hz. Thus, reducing this type of tremor will help improve patients’ quality of life. In this paper, to suppress resting tremors, an intelligent glove was designed utilizing the concepts of vibrations and gyro effect. A rotating brass disc attached to the glove creates a gyroscopic effect of the smart glove. Therefore, the disc will do their utmost to stay upright and counter any input forces instantaneously by providing the counterforce. A reduction of more than 50 % with the intelligent glove is also shown

SAR Evaluation of Metallic Loop-like Accessory Effect of Broadband Wearable Planar Monopole Textile Antenna

This paper presents the investigation influence of the common metallic loop like accessory on Specific Absorption Rate (SAR) averaged over 10g and 1 g tissue.The simulations were made by means CST Microwave Studio software at frequencies 2.45GHz and 2.6GHz. Numerical analysis conducted using broadband textile monopole antenna (TM) with variations of orientation and distance showed that the SAR value increased when the antenna horizontally polarized.This is up to 80% more than vertically polarized TM placed closest item to 2mm

Fuzzy logistic equation by polynomial interpolation

The aim of this paper is to study the fuzzy logistic equation. In this paper, the problem of best approximation is considered for fuzzy function, by interpolation to obtain a polynomials. This problem is solved numerically using the extended Runge-Kutta-like fourth order method which use less function evaluations. The extended Runge-kutta-like fourth order method will be briefly described. Polynomial operation with degenerate interpolation will eventually involve Vandermonde matrices. Finally, this paper shows that fuzzy logistic equation gives acceptable result

The application of fuzzy logistic equations in population growth with parameter estimation via minimization

This paper presents a numerical solution for the first order fuzzy logistic equations by extended Runge-Kutta fourth order method with estimated parameters. The parameters are estimated by minimization technique using conjugate gradient approach. Then, the fuzzy logistic model with the estimated parameters is used to fit the population growth in Malaysia. Numerical example is given to show the efficiency of the proposed model

Laboratory rearing of Elaeidobius kamerunicus Faust (Coleoptera: Curculionidae) pollinator of oil palm inflorescence in Malaysia

This study was conducted to evaluate laboratory rearing of Elaeidobius kamerunicus through observation of its life development and survivability on an artificial diet and anthesising male inflorescence of oil palm as the natural feed. The experiment was the three adopted diets compared with rearing on natural feed toward the survivability and life development of reared larvae Elaeidobius kamerunicus. The AMI of oil palm was the successful diet for the survival of weevil larvae with around 11 days to develop from egg to adult. The improved natural feed is calculated to have a longer time for 50% mortality than the first natural feed, where it had double the time requirement. Moreover, improving the natural feed rearing method had increased survivability from around 20% to almost 50%. Furthermore, they improve natural feed enables shorter life development at 10 days. Thus, this study provided the method for rearing E. kamerunicus through the natural feed for better key survival and management
