A fraction is a complex topic in mathematics. Some literature indicates that students made mistakes in solving mathematical problems involving higher order thinking skills which are related to Number domain. The Number domain includes Whole Numbers, Sequences and Patterns of Numbers, Fractions, Decimals, Percentages and Integers. Therefore, this study was conducted to determine the effectiveness of Thinking Blocks in order to help students solve fraction problems involving higher order thinking skills. By incorporating a pre-post quasi-experimental design, students were divided into two groups. The experimental group (n = 32) were exposed to treatment to improve higher order thinking skills. Whereas, the other group acted as a control group (n = 22) and were taught in a conventional way. Samples involved in this study were Form One students in Johor. The instrument used in identifying the level of higher order thinking skills consists of twelve higher order thinking questions. The g...

DC motors are having wide range of application from household appliances to large industrial machinery at various speed conditions. In this paper, speed control of a separately excited direct current (DC) motor under load conditions has been implemented using CHR tuning and LQR controllers. The Chien-Hrones-Reswick (CHR) is based on a Proportional Integral Derivative controller (PID) tuning and Linear Quadratic Regulator controller (LQR) is based on an optimal controller. Comparison of both the methods have been done based on transient response specifications. Simulations in MATLAB have shown that the performance of the DC motor has significantly improved quality response with the LQR method over the CHR method. It has also minimized deviation from the desired speed, with the LQR method. This can lead to significant improvement when implemented in applications viz. robotics, process control and cruise control.

Scientific research as one of the three pillars in university education is considered. The process of development of research skills in students of Medical Sciences has been attributed great interest both internationally and nationally. Magazine April 16 has played an important role as a means of disseminating science produced by our students. They were calculated indices related to productivity and visibility of this journal based data on Google Scholar through the Publish or Perish. It was considered to be work permanently to improve the quality and scientific level of this medium.
