Currently, several offline digital simulation software tools are available, with varying degrees of modeling and simulation capabilities. This paper aims to compare the capabilities of two program packages for electric network simulation: ATP-EMTP and PSCAD/EMTDC for modeling lightning overvoltages. 2000 Mathematics Subject Classification: 68Uxx/Subject Classification for Computer Science. 281,...

Introduction: In Pharmacy Diploma Program, mathematics is known as pharmaceutical mathematics. Due to the importance of pharmaceutical mathematics in practice, it is important to have a basic mathematical skill as a basis in calculations in pharmaceutical science. Therefore, it is necessary to create a lecturing condition that enables students more active in understanding the lessons. This rese...

Using a cluster randomized trial, we investigated the effects of mathematics professional development on student achievement in elementary schools. Pairs schools were matched prior mathematics; percentage students receiving free or reduced-price lunch and limited English proficient randomly assigned to two groups. One received that focuses diagnosing thinking other formative assessment. Student...

the control problem and dynamic programming is a powerful tool in economics and management. we review the dynamic programming problem from its beginning up to its present stages. a problem which was involved in physics and mathematics in i 7” century led to a branch of mathematics called calculus of variation which was used in economic, and management at the end of the first quarter of the 20” ...

A “mathematics for non-mathematicians” course, commonly known as a “service” course is an undergraduate mathematics developed students who are not (going to become) majors. Besides calculus, such courses may include linear algebra, mathematical reasoning, differential equations, programming and modeling, discrete mathematics, teachers, so on. In this article we argue that good, productive curri...
