Over the last few years, the use of the internet services and applications such as phone calls, e-mails, video conferencing, catch up TV, audio and video streaming in general, which heavily rely on the network communications has increased. Reliable connections between the end users are vital for providing such internet services. In such networks, link or node failures can occur suddenly and without any notifications which will make more interruptions for the data transmission between source and destination. Hence, the network performance will be reduced significantly since more time is needed to reroute the traffic, which can create sever interruptions for delay sensitive services such as voice and video. A pre-computed backup path in advance can provide a valuable solution to reroute the data packets during the network recovery time. In this book, we study several factors to compute the backup path between source and destination such as (network design, Bandwidth, Shortest path). We show results of several efficient algorithms that have been implemented to compute the best backup route until the routing protocol re-updates the new routing table.6374 Руб.
Energy conservation is equivalent to energy generation and transmission at 100% efficiency. Combined heat and power (CHP) is an important concept as fuel is used to generate two different forms of energy simultaneously. This book reports a project done at a bottle-cap manufacturing company, where a diesel generating set is employed as backup source of electrical energy. The possibility of using heat from exhaust gases to heat thermic fluid is explored. The design process for the heat recovery heat exchanger and other components is presented. The hot thermic fluid can be used for process heating for making the bottle-caps. It is estimated that around 50 kW heat can be recovered using a shell and tube heat exchanger for the 125 KVA diesel generator set. The payback period is around 480 days. This work thus demonstrates feasibility of such CHP system for process industries. It would also help people in the trade to design such system and also evaluate them.3274 Руб.
