One of the biggest problems in teaching Mathematics is the motivation of students (Kloosterman, 1997;Lambic, 2008). The core of this problem is insufficient comprehension of reasons by students, why they want to learn Mathematics and in which way they could apply acquired knowledge of Mathematics (Southwell, 1994;Musto, 2008). Since programming is closely connected to Mathematics, this try has been compiled to make Mathematics closer to students with a help of working with software C++ Builder. The students from higher grades of elementary schools, high school students and university students have been participating in this project. Without previous knowledge of programming languages, the students were given tasks to create a certain computer program. The students have been making programs by inventing algorithms and setting visual components of the program, while the teacher, on their request, has been doing programming as part of the work. At the end of the project, the students have shown much better attitude towards the Mathematics class than before, and they have also obtained certain skills and knowledge in the programming field.

The article discusses research done in the area of computer compiler technology, which is defined as a computer program that translates a program written in a high-level language into another language, usually machine language. 2007 was the 50th anniversary of IBM's (International Business Machine's) release of the first optimizing compiler, the authors state. Topics include directions compiler technology make take from 2009 and beyond, a review of past contributions to compiler technology, and the status of compiler technology in 2009.

Most users of Computer Numerically Controlled (CNC) Automated Fiber Placement (AFP) machinery use off-line Numerically Controlled (NC) programming software supplied by the machine builder. This machine builder-supplied software only works with their specific machine, forcing manufacturers to implement multiple off-line NC programming products when using multiple brands or vintages of machines. The more mature CNC metal-cutting industry started the same way, but has now evolved into a clear separation and cooperation between independent software and machine suppliers. This has freed the end-user company to select the best machine for the job, while using one universal software application to create NC programs for a variety of machine brands or vintage. When combined with composite design software tools that specifically take into account AFP manufacturing requirements early in the product development cycle, engineering and manufacturing specifications are seamlessly transferred to the manufacturing process. This paper discusses the implementation and use of machine-independent off-line NC programming software as it applies to CNC fiber placement machines.

software-only reliability techniques protect against transient faults without the overhead of hardware techniques. Although existing low-level software- only fault-tolerance techniques detect faults, they offer no recovery assistance. This article describes three automatic, instruction-level, software- only recovery techniques representing different trade-offs between reliability and performance.

A simulation model for establishment of performance parameters of a spark ignition engine fueled with landfill gas, methane, and landfill gas-hydrogen mixtures is described. A two zone model was employed to estimate combustion duration, ignition lag, associated mass burning rates, and performance parameters for various operating conditions in an internal combustion engine. The modeling consists of two main modules: ( a) a fuel-air and residual gas properties calculation, and (b) equilibrium combustion product properties calculation with 13 species of equilibrium combustion products. The fuel-air and residual gas module calculates gas properties required in compression stroke and the unburned zone of a combustion chamber. The equilibrium combustion products module calculates gas properties for the burned zone during combustion and expansion phases. In addition to engine parameters, combustion duration estimation methods were presented to accommodate the presence of high quantities of diluents such as carbon dioxide and nitrogen in methane to represent landfill gases, generally encountered in practice. Similarly, an effect of the addition of hydrogen in landfill gas on performance of a spark ignition engine was also incorporated in the model. The pressure traces and engine power output parameters were modeled and compared with the experimental observations obtained in a variable compression single cylinder four-stroke spark ignition cooperative fuel research engine for different fuels that include methane, landfill gas, and landfill gas-hydrogen mixtures and found satisfactory agreement. MATLAB was used as the programming software in the model. [DOI: 10.1115/1.3185344]

An algorithm for the automatic reconstruction of data types from the assembler code produced by a C compiler is described. The types of the variables that are placed on the stack and in the static memory are reconstructed using an iterative algorithm that uses a lattice over the properties of the data types. The derived data types are reconstructed by constructing the set of possible offsets of the elements of these types ( fields in the case of structures and array elements in the case of arrays). This algorithm is used in the tool for decompiling assembler codes into C that is currently developed by the authors.

A problem of automated construction of configuration tables for real-time operating systems is considered. software configuration information is categorized as follows: information depending on the target function of the system, information depending on the operating system (OS), and information depending on system hardware. For a specialized system meant for automated design of OS configurations, information links are established between its components and other functional elements of the programming software as part of the programmer's workplace. An automated software configuration environment developed by the authors of this paper is described. An example of working windows of a program for automated design of software configurations for avionics under control of the ARINC 653 compliant real-time operating system is presented.

In this paper, the effect of voids, relaxation times, thermomechanical coupling, surface conditions, and plate dimensions on energy dissipation induced by thermoelastic damping in microelectronics mechanical systems (MEMS)/ nanoelectronics mechanical systems (NEMS) resonators are investigated. Closed form expressions for the transverse vibrations of a homogenous isotropic, thermoelastic thin plate with voids, based on Kirchhoff theory have been derived. The exact solutions for the free vibrations of plates under clamped-simply supported (CS) and simply supported-simply supported (SS) conditions are obtained. Analytical expressions for deflection, temperature change, frequency shifts, and thermoelastic damping in the plate have been derived. Some numerical results with the help of MATLAB programming software in case of silicon nitride and magnesium like material have also been presented.
