In this book, an experimental analysis of compact biogas plant is performed using biogas produced with the help cow dung and algae. During the production of biogas by cow dung, methanogenic bacteria produced and it can be recycled again and again. After that another wastage i.e algae is used and found almost the same production rate in both cases. During the process, affecting parameters of biogas like pH, temperature, retentions time, feedstock's according to the capacity of biogas plant also studied and to find a relation between time, temperature and volume. Biogas can be produced by household wastages if people utilized in a proper manner.

Damping in Fiber Reinforced Composite Materials starts with an introduction to the basic concepts of damping in composite materials. Methods of modeling damping are then covered, along with recent developments in measuring techniques, both local, like polar scanning and global techniques like the Resonalyser method (based on measuring modal damping ratios of composite material plates). The effect of other factors, such as stress, strain-level, stiffness and frequency that need to be considered when determining damping behavior in composite materials are also discussed in detail. Other chapters present a parametric study of a two-phase composite material using different micromechanical models such as Unified micromechanics, and Hashin and Eshelby’s to predict elastic moduli and loss factors. A bridging model that incorporates the effect of fiber packaging factors is then compared to FEM results. Final sections cover the effect of the interphase on the mechanical properties of the composite, present a nonlinear model for the prediction of damping in viscoelastic materials, and provide practical examples of damping and principles of vibration control.
