But, over the past few decades, students with engineering as their major have declinedeven in technically advanced countries like the United States.1 Therefore, the youngsters shouldbe encouraged and facilitated with tutorials, seminars and educational programs to augment theirinterest and knowledge in advanced technologies in order to expand a capable work force fornext generation. Nanotechnology has rapidly emerged among other fields of science and engineering.Growth and development of this field over the last few years has convinced researchers andscientists that it can sustainably knock over the prevailing technological models.2 It has beenspeculated in many reports from

In most thermodynamics textbooks [1-9] it is assumed thatspecific volume, specific internal energy, and specific entropy of fluids in the compressed liquidregion are functions of temperature only and pressure effects are negligible. Therefore, thefollowing expressions are presented in the textbooks to approximate these properties at a giventemperature and pressure. v T, p vf T (1) u T, p uf T

In aircraft design, a process is executed such that all thedisciplinary studies of aeronautics are applied to produce together one single concept fora vehicle to be built followed by more detailed planning phases. The design is first of allachieved by creating a conceptual shape of the aircraft made by a convergence ofvariables that best fit the subjected mission requirements. The following seven steps givean overview of the conceptual design for an aircraft: 1) Analysis, 2) Integration, 3)Iteration, 4) Convergence, 5) Solution Space Screening, 6) Solution

Instead, they will ascribe negative personality traits and behavior to each other.That is because different cultures tend to assign differing interpretations to specific words,phrases, texts, and situations. Thus, what may be polite interaction in one culture may be aninsult in another. Furthermore, although Participant A may have learned Participant B’s language and speak it well with him or her, nevertheless, speaking the same language does not meanassigning the same meanings to spoken or written words.

Like any design problem, afew error-corrections, adjustments of parameters or even modification of the initial circuitdiagram may be required. Although not very difficult, the text-based input method can be a littleintimidating for a beginner and hence it is not focused in this paper.
