Adaptive sample size and sampling intervals schemes have been widely used to improve the statistical efficiency of Hotelling T² control chart in detecting small changes when the quality of a product or a process can be characterised by the multivariate distribution of quality characteristics....

Satellite measurements of volcanic sulfur dioxide (SO<Subscript>2</Subscript>) emissions can provide critical information for aviation hazard mitigation, particularly when ash detection techniques fail. Recent developments in space-based SO<Subscript>2</Subscript> monitoring are discussed, focusing on daily, global ultraviolet (UV)...</subscript></subscript>

Product development (PD) is a broad field of endeavor dealing with the planning, design, creation, and marketing of a new product. This revolutionary research domain has become of paramount importance to beat the competition for multidisciplinary products which are larger in size and have a...

To achieve energy saving and emission reduction for vehicle diesel engines, the organic Rankine cycle (ORC) was employed to recover waste heat from vehicle diesel engines, R245fa was used as ORC working fluid, and the resulting vehicle diesel engine-ORC combined system was presented. The...

This study analyzed the variation law of engine exhaust energy under various operating conditions to improve the thermal efficiency and fuel economy of diesel engines. An organic Rankine cycle (ORC) waste heat recovery system with internal heat exchanger (IHE) was designed to recover waste heat...

To achieve a goal of reducing the emission intensity of carbon dioxide in 2020 by 40–45% relative to 2005 in China, the framework for a low-carbon scenario was developed on a small scale in Minhang District, Shanghai. The STIRPAT model was employed to reveal the factors that contribute to CO2...

With the rapid development of mobile smartphone and its built-in location-aware devices, people are possible to establish trust relationships and further interaction with each other based their matched interests, hobbies, experiences, or spatiotemporal profiles. However, the possibility of...

Wireless sensor networks (WSNs) is a key technology which is deployed under the assumption that participating sensors are cooperative in forwarding each other's packets. However, some nodes may behave selfishly by dropping other's packets or refusing to provide services in an attempt to maximize...

Aiming at the recovery of exhaust energy for a diesel engine, a set of ORC (organic Rankine cycle) system is designed. The characteristics of the exhaust gas under various operating conditions are studied through experiment. Based on experimental results and theoretical calculation, effects of...
