Proper dissipation of thermal energy from a system is always a requirement for many equipment and industries. Any device that runs using external power source always generates heat. The generated heat in such systems must be expelled to the surrounding. Maximizing the surface area of the devices generally enhances the cooling rate. However, it makes the system bulky. Therefore, a proper utilization of the surface area of the system is an important parameter to have an efficient heat dissipation system. It was always desirable to have a heat sink in the all devices that occupy minimum space with maximum effectiveness. The present work analyse conjugate heat transfer physics in a 3-D system of aluminium pin fins, with air as the working fluid. A finite volume solver, ANSYS Fluent has been used in simulating a staggered pin fin arrangement placed over a base plate. The solver is validated using the experimental data. The thermal analysis has been performed on fins with various cross sections. Consideration is given to fins having circular, hexagonal, pentagonal, triangular and drop-shaped cross sections with various inlet velocities.

While on the one hand the study ascertains the market rates of return (earned) on equities from the investors' perspective (by including both the capital gains and the dividend income), it also shows how to compute the rates of returns on equities from the corporate perspective (that is, rate of return earned on equity funds).

The book examines the market reaction to mergers and acquisitions (M&A) announcements over a period from 2003 to 2015. In addition, the book investigates the corporate governance practices of the acquiring firms and their impact on the short- term as well as long- term performance of those firms.

Based on a data set covering the last two decades of India's development, this study analyzes the financial performance of public sector enterprises, assessing their success in adapting to a liberalized business environment of disinvestment and subsidy cuts.

This book examines whether there has been a major change in the financial profitability and financial policies and decisions of sample companies in the period from 2000-2001 to 2010-2011, with a special focus on pre and post-recession analysis.
