The objective of this study is to present a mathematical modeling and solution approach for the drying process of spheroidal solids with the application of microwave in capillary porous media based on the Luikov equations, composed of a system of linear and coupled partial differential equations arising from the energy, mass and pressure balances inside the solid matrix. Additionally, the power...

Multimedia authoring is still subject to computer experts with programming knowledge. Most multimedia systems provide fixed concepts for the specification of the temporal and spatial layout of multimedia documents. Starting with interaction some approaches require script programming by authors. Special effects like animations, complex interactions or alternative concepts have to be programmed i...

We present a new approach to teaching programming language courses. Its essence is to view programming language learning as a natural science activity, where students probe languages experimentally to understand both the normal and extreme behaviors of their features. This has natural parallels to the “security mindset” of computer security, with languages taking the place of servers and other ...

Introduction In 1953 IBM introduced an early “automatic-programming” system: Speedcode for the IBM 701 computer. The goal of the system was to [l] “. . . lessen the enormous burdens of the programmer by providing a larger and more convenient instruction repertoire than a given machine provides.” In the same paper John Backus and Harlan Herrick go on to state: “There are two principal methods by...

This paper seeks to contribute to the growing literature on children and computer programming by focusing on a programming language for children in Kindergarten through second grade. Sixty-two students were exposed to a 6-week curriculum using ScartchJr. They learned foundational programming concepts and applied those concepts to create personally meaningful projects using the ScratchJr program...

Computer programming is among the fundamental aspects of computer science curriculum. Many students first introduced to introductory computer programming courses experience difficulties in learning and comprehending. Vast amount of researches have revealed that, generally programming courses are regarded as difficult and challenging and thus often have the highest dropout rates. Moreover, numer...

A multitude of problem-oriented programming languages are being created in order to facilitate programming in various fields.Th~se languages have two advantages for non-programmers who need a computer for solving their problems: I. they are not forced to spend much time on learning a complicated machine language; 2. they do not necessarily have to alter their programs when they are obliged to u...

Recently Java programming environment has become so popular. Java programming language is a language that is designed to be portable enough to be executed in wide range of computers ranging from cell phones to supercomputers. Computer programs written in Java are compiled into Java Byte code instructions that are suitable for execution by a Java Virtual Machine implementation. Java virtual Mach...

Teaching object-oriented programming has clearly become an important part of computer science education. We agree with many others that the best place to teach it is in the CS1 introductory course. Many problems with this have been reported in the literature. These mainly result from inadequate languages and environments. Blue is a new language and integrated programming environment, currently ...

In today's digital era information access is just a click away. so computer science students also have easy access to all the source codes from different websites thus it has become difficult for academicians to detect source code reuse in students programming assignments. The new trend in the area of source code reuse is using the source code by translating it in another programming language p...
