ANALYSIS OF BACKPACK RESPONSE TO TRUNK MOTION DURING LOAD CARRIAGE ACTIVITY

A backpack vibration system consists of a backpack?human trunk system, was developed to examine the backpack’s response to trunk motion when carrying a load and to determine which damping and stiffness parameters give the best result for a stable backpack vibration system. The vibration system was analysed using different values for the damping and spring coefficients in the displacement and velocity equations of the backpack vibration system. Given a backpack mass of 3.5 kg, the vibration system oscillates with a stable condition damping value of c = 2 Nsmm-1 and a stiffness value of k = 5 Nmm-1

Penyelesaian terus persamaan pembezaan biasa peringkat tiga menggunakan kaedah blok hibrid kolokasi diperbaiki

The improved block hybrid collocation method (KBHK(B)) with two off-step points and four collocation points is proposed for the direct solution of general third order ordinary differential equations. Modification is done by adding first derivative of third order function into the general form of block hybrid collocation method to yield KBHK(B). Both main and additional methods are derived via interpolation (power series function) and collocation of the basic polynomial. An improved block method is derived to provide the approximation at five points concurrently. Zero stability, consistency, convergence and absolute stability region of KBHK(B) are investigated. Some numerical examples with exact solution are tested to illustrate the efficiency of the method. KBHK(B) is compared by other block hibrid collocation method in term of global error and step number. It is shown that KBHK(B) generates minimum global error with minimum step number

Transforming Arithmetic Asian Option PDE to the Parabolic Equation with Constant Coefficients

Arithmetic Asian options are difficult to price and hedge, since at present, there is no closed-form analytical solution to price them. Transforming the PDE of the arithmetic the Asian option to a heat equation with constant coefficients is found to be difficult or impossible. Also, the numerical solution of the arithmetic Asian option PDE is not very accurate since the Asian option has low volatility level. In this paper, we analyze the value of the arithmetic Asian option with a new approach using means of partial differential equations (PDEs), and we transform the PDE to a parabolic equation with constant coefficients. It has been shown previously that the PDE of the arithmetic Asian option cannot be transformed to a heat equation with constant coefficients. We, however, approach the problem and obtain the analytical solution of the arithmetic Asian option PDE

Industrial Training as a Benchmark of the Employability for the Mathematical Sciences Students of UKM

AbstractIndustrial Training course (ITc) is a student's placement programme in organizations outside the Universiti Kebangsaan Malaysia (UKM). The aims of the training are to expose students to real working environment and enhance the knowledge and skills in their profession. The program is expected to produce students with competencies required by employers. This study was conducted to determine the effectiveness of the ITc in providing work experience to students of Mathematical Sciences. In addition, feedback from the industries on skills and abilities of Mathematical Sciences students in performing their tasks is obtained. Information from students and employers are collected through questionnaires which were distributed to all Mathematical Sciences students who undergo ITc and the employers during the ITc assessment visits. Analysis of the survey shows that overall, Mathematical Sciences students agreed that the program is helpful in providing exposure and experience to them. From the perspective of employers, the findings show that the employers are satisfied with the skills and abilities of the students in carrying out the assigned tasks

Transformation of Language in Teaching and Learning Policy

AbstractDue to the abolishment of the Teaching and Learning of Science and Mathematics in English (PPSMI) policy by the Malaysian Cabinet in July 2009, a new policy which is called Upholding the Malay Language and Strengthening Command of English (MBMMBI) policy was introduced. Both languages have their role and importance. The Malay language has long since been the language of knowledge and unity in Malaysia, whereas English is the international communication language. This study focuses on students’ perspectives regarding the issue of the transformation from PPSMI to MBMMBI. A survey has been conducted to gather information from students who enrolled for Science and Mathematics courses. Results show that the students are taking a positive standpoint in upholding the Malay language and at the same time strengthening the command of the English language. The transformation from PPSMI to MBMMBI is hoped to generate Malaysians who are fluent and confident in both Malay and English languages

Teaching Science and Mathematics in English Steering Mastery in English Language Amongst Sciences Students in UKM

AbstractThis study was conducted to ascertain teaching Science and Mathematics in English will enhance English proficiency amongst the science stream students in UKM. The study found that the students agreed that the teaching of Science and Mathematics in English can improve their English proficiency. The results showed that teaching Science and Mathematics in English is capable of being a driven force in mastering basic English language and communication, and also in improving the explanation of the concept of Science and Mathematics in English

Students’ Inclination towards English Language as Medium of Instruction in the Teaching of Science and Mathematics

AbstractMalay language, the national language of Malaysia has been the medium of instruction for Science and Mathematics for the past four and a half decades in Malaysia. The government however changed the medium of instruction of these subjects to English in January 2003. The “Teaching and Learning of Science and Mathematics in English” (PPSMI) policy was implemented in all primary and secondary schools. It aims to improve the English language proficiency among students as well as the learning and achievement level in science and mathematics. This paper presents findings of the study on students’ inclination towards English language as medium of instruction in teaching and learning of Science and Mathematics in Higher Learning Institutions in Malaysia. The respondents were 291 undergraduate students from the Faculty of Science and Technology (FST) and Faculty of Education (FPEND) of Universiti Kebangsaan Malaysia (UKM). A questionnaire pertaining to students’ inclination was used as research instrument. Using descriptive statistics, ANOVA and t-test, the study found that undergraduate students of FST and FPEND had an inclination towards English as medium of instruction in the teaching and learning of Science and Mathematics. Using the Post-Hoc test, it is found that Indian students and students from other races than Malay and Chinese have greater inclination towards English as medium of instruction in teaching and learning of Science and Mathematics in UKM for both faculties. However, FST students who studied in Mandarin and Tamil at pre-university level (STPM) had higher inclination compared to those who used Malay language or even English
