|
|
|
|
electric vehicles. It provides a fundamental framework for this topic and important basic data and references for insulation materials used in these systems. It covers the aging of photovoltaic systems installed in different environments, including space, as well as the aging of the discharge present in the drive motors of electric vehicles. This book is suitable for researchers and students interested in green energy systems and can be used for teaching, research, and science popularization. |

The book presents some key mathematical tools for the performance analysis of communication networks and computer systems.Communication networks and computer systems have become extremely complex. The statistical resource sharing induced by the random behavior of users and the underlying protocols and algorithms may affect Quality of Service.This book introduces the main results of queuing theory that are useful for analyzing the performance of these systems. These mathematical tools are key to the development of robust dimensioning rules and engineering methods. A number of examples i |
