In order to be suitable for tribological applications, polymeric materials, which can usually
exhibit mechanical strength, lightness, ease of processing, versatility and low cost, together
with acceptable thermal and environmental resistances, have to show good abrasion and
wear resistance. This target is not easy to achieve, since the viscoelasticity of polymeric
materials makes the analysis of the tribological features and the processes involved in such
phenomena quite complicated.
Other than this, automation and optimization of production engineering was attempted
in various fields. Okumoto et al. (2005D) optimized the block allocation on the
assembly area using simulated annealing method. Wibisono et al. (2007) optimized
block division planning using genetic algorithm and product model. Universal
Shipbuilding Corporation (2008) developed a high performance NC Printing Machine,
which enables fast printing irrespective of the number of characters and lines to be

This book is designed for a one-semester course on Nano- and
Microelectromechanical Systems or Nano- and Microengineering. A typical
background needed includes calculus, electromagnetics, and physics. The
purpose of this book is to bring together in one place the various methods,
techniques, and technologies that students and engineers need in solving a
wide array of engineering problems in formulation, modeling, analysis,
design, and optimization of high-performance microelectromechanical and
nanoelectromechanical systems (MEMS and NEMS).
In this paper, we are dealing with a L-band power combiner method using the Wilkinson bridge. This is a modern power combination technique in the microwave technology. The design and simulink of the basic power moduls and Wilkinson bridge were performed using the ADS soflware. We have researched, designed and fabricated the power combination from the basic 200W moduls. The experimental results showed that power combination method using the Wilkinson bridge may be applicable in the L-band transmission....
Organic light-emitting diodes (OLED) are playing a major role in information technology
(IT) by providing the promise of further expanding the use of digital displays
through making display fabrication technology lower in cost and higher in performance
to replace liquid crystal displays (LCD). Due to various attractive features such
as high contrast, high brightness, large color gamut and thin structure, various sized
OLED displays from small-sized mobile phone display to large-sized TV display have
already begun to be mass-produced....
