Measurement and computional techniques are an integral part of a research, it contains articles of interest to all who are engaged in the study and application of fundamental measurement. With the advancement of technologies and research areas, there is paradigm shift in different measurements and computational techniques. Instrumentation/measurement are the area that has synergistic combination of all major area of science and engineering e.g. mechanical/electronic/ instrumentation/computer and design engineering to achieve precise and accurate measurement information. It is a multidisciplinary field involving material science, sensors & actuators, optics, signals processing, statistics, computation, communication. The applications for this field are visible in almost all area of science and engineering i.e. electrical, electronics, mechanical, mining, civil, agriculture, safety, communication, manufacturing, processing and many more. Computational methods and techniques are all the heart of modern research and development. These are basically used to facilitate the discovery and design of product with new functionalities and desired properties. These methods have a major role in the design and optimization of routes for materials synthesis, manufacturing processes and preparing final product. The computational techniques are also being used in computational reswarch i.e. in the analysis/interpretation of experimental characterizations and sophisticated calculations. In the present book, editor has touched some of the areas related to the computation and measurement techniques with the expectation that this book will provide a basic understanding od research to the reader. The topics incorporated are related to the fundamentals of computation and measurement techniques that are prevalent in the experimental and theoretical engineering, however, these ecperimental finding can be applicable to other areas of science and engineering. Best efforts to make this book more interesting and expect that this book will offer broad examples of existing development in the research.
