The purpose of this paper is to present a four point direct block one-step method for solving directly the general second order nonstiff initial value problems (IVPs) of ordinary differential equations (ODEs). The mathematical problems in real world can be written in the form of differential equations and arise in the fields of science and engineering such as fluid dynamic, electric circuit, motion of rocket or satellite and other area of application. The proposed method will estimate the approximation solutions at four points simultaneously by using variable step size. Numerical results are given to show the efficiency of the proposed method.
To statistically analyse sitting posture using anthropometrics data among college students in Malaysia.
This study was conducted among 52 college students consisting of males and females. Data were analysed using a common statistical tool which is the Statistical Package of Sosial Science (SPSS).
Preliminary analysis of data indicated that there are wider differences in standard deviation of eye sitting height compared to the previous study conducted.
This study was conducted at only one higher learning institution/college located at East Cost of Malaysia.
The larger value of standard deviation discovered as statistical analysis performed using combined data among male and female participants suggested that data should be segregated.
Result obtained could be used as a preliminary guideline to design any related item in related to sitting posture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
