Measurment and computational techniques are an integral part of a research; it contains articles to all who are engaged in the study and application of fundamental measurement. With the advancement of technology and research areas, there is paradigm shift in different measurement and computational techniques. Instrumentatin/measurement are the area that has synergistic combination of all major areas of science and engineering e.g mechanical/ electronic/ instrumentation/ computer and design engineering to achieve precise and accurate measurements information. It is multidisciplinary field involving matreials, mining, civil agriculture, safety, security, communication, manufacturing, processing and many more. Computational methods and techniques are at the heart of modern research and development. These are basically used to faciliate 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 processess and preparing final product. The computational techniques are also being used in computational research i.e. in the analysis/ interprtation of experimental characterizations and sophisticated calculations. In the present book, editor has touch some of the areas related to the computation and measurment techniques with the expectation that this book will provide a basic understanding of research to the reader. The topics incorporates are related to the fundamental of computation and measurment techniques. Few chapter are seems to be from the field of mechanical engineering, however, these expwerimwter finding can be applicable to other areas of science and engineering. Best efforts to make this book more interesting and expert that this book will offer broad example of existing development in the research. Lastly, the constructive suggestions are welcomed from the users of this book for the enhancement of quality of the book.
