Recently it has been widely acknowledged that the recognition of emotions of computer users can provide more user friendly systems and eventually increase the productivity of users. User friendly interfaces are even more important for the design of educational software that is appropriate for young children. In human-human interaction the expression of emotions of people can be evident in diffe...

Both software applications and their development environment are becoming more and more distributed. This trend impacts not only the way software computes, but also how it looks. This article proposes a Human Computer Interface (HCI) template from three representative applications we have developed. These applications include a Multi-Agent System based software, a 3D Internet computer game with...

By emphasizing the application of computer programming not only in success stories in the software industry but also in familiar scenarios in physical and biological science, engineering, and applied mathematics, Introduction to Programming in Java takes an interdisciplinary approach to teaching programming with the Javaв„ў programming language. Interesting applications in these fields foster a...

Arising from research in the computer science community, constraint programming is a relatively new technique for solving optimization problems. For those familiar with mathematical programming, there are a number of language barriers that exist that make it difficult to understand the concepts of constraint programming. This paper, which assumes a minimal background in linear and integer progr...

A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...

Primarily because of its young age, Python is still a language that people only discover after having digested a few others: while many of its users love it enthusiastically, almost nobody is a native speaker of it, in the sense of having been exposed to it before any other. As computer literacy evolves from desirable to necessary for people from all backgrounds, computer professionals and acad...

We present a numerical algorithm for computing rigorous upper and lower estimates of the principal eigenvalue p-Laplacian. To control all possible errors including rounding computer arithmetic, we use interval arithmetic. implement our in Julia programming language using IntervalArithmetic.jl package [12].

Assembly language programming has been for long used as a teaching tool for computer systems. However, this approach suffers from the difficulties that are inherent to its low-level instructions. The present teaching approachmerges the assembly language course with microcomputers technology by means of structured pseudo-coding. The method is based on a classification of the assembly instruction...

When programming in languages such as C, Java, etc., it is difficult to reconstruct the programmer's ideas only from the program code. This occurs mainly because, much of the programmer's ideas behind the implementation are not recorded in the code during implementation. For example, physical aspects of computation such as spatial structures, activities, and meaning of variables are not require...

This paper is about Q-Midi, an interface for developing MIDI applications in the Q programming language. Q is a modern functional language based on term rewriting; this means that a Q program is just a collection of equations which are used as rewriting rules to simplify expressions. Q-Midi represents MIDI events as symbolic data which makes it easy to formulate functional programs to manipulat...
