  • This chapter is devoted to ‘‘fundamental’’ fundamentals—certain principles which lay the foundation for what is to come. Starting with the original author’s suggested thought process for analyzing typical problems, the reader is then exposed to a buzzword of our time: value engineering. Next follows a discussion of codes and regulations, political criteria which constrain potential design solutions to the bounds of public health and welfare, and sometimes to special interest group sponsored legislation....

  • When the plastic melt fills the mold, it displaces the air. The displaced air must be removed quickly, or it may cause burn spot (due to the fast compression of trapped air pocket by the low-thermal-conductivity polymer melt), or it may restrict the flow of the melt into the mold cavity, resulting in incomplete filling (short-shot problem). Consider the injection-molding of a air bag housing. Notice that the part consists of a thin central region and a thick rim around it. A single gate is adopted in the original design. Most of the melt flow along the part side since...

  • The research, simulation and design dual band antenna which operates at 900MHz and 2.45GHz are conducted. FR4-epoxy substrate is chosen with thickness h = 1.5mm, εr = 4.4. Dual band can be achieved by using different methods of impedance’s matching for single antenna which is originally designed at 900MHz. Some dual band RFID structures are discussed in this paper.

  • This paper describes the components used in the design of the commercial X u x e n I I spelling checker/corrector for Basque. It is a new version of the Xuxen spelling corrector (Aduriz et al., 97) which uses lexical transducers to improve the process. A very important new feature is the use of user dictionaries whose entries can recognise both the original and inflected forms. In languages with a high level of inflection such as Basque spelling checking cannot be resolved without adequate treatment of words from a morphological standpoint.

  • In this paper, the five-band notch filter was designed using MATLAB and implemented by the floating-point digital signal processor TMS320C6711 based on TI's DSP starter kit (DSK) board connected to the parallel port of the PC through the DB25 cable included with the DSK package. The original segment of symphony orchestra corrupted two undesired sinusoids at frequencies of 750Hz and 1750Hz is conduced to input of DSK to produce the corrupted input signal which is saved in the wave file (Corrupthandel.wav) for the digital signal processor. ...

  • In this chapter we explore en elegant and powerful approach to problem solving recursive problem solving. Recursive problem solving involves breaking a problem into identical, but smaller or simpler problem instances and solving those to obtain a solution to the original problem. Most programming languages, including Java, support the use of recursion to solve problems.

  • Design patterns have been around for quite a few years. They were originally created by the Gang of Four (Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides), which is responsible for formalizing the accepted design patterns we use today. Their use, while questioned and argued over by different programming schools of thought, has generally been accepted as “best practices” within the development community. The original takeoff of design patterns was brought about in the Java and C++ world...
