In-use, fuel-based motor vehicle emission factors were determined using measurements made in a highway tunnel in Pittsburgh, Pennsylvania. Concentrations Of PM2.5 mass, CO, CO2, and NO, were measured continuously. Filter-based measurements included PM2.5 m ...
The dissertation deals with closed-loop product lifecycle management (PLM) approaches for the product conceptual design improvement using gathered data during the usage period of a product. In closed-loop PLM, the data generated in each lifecycle phase can ...
Rock avalanches are catastrophic phenomena which are not yet exhaustively understood. They consist of rock mass movements of more than one million cubic metres, involving a great amount of energy and travelling farther than expected with a normal sliding f ...
Presently, a remote steering (RS) antenna [C.P. Moeller, A method of remotely steering a microwave beam launched from a highly overmoded corrugated waveguide, in: Proceedings of the 23rd International Conference on IRMMW, Colchester, UK, 1998] is envisione ...
A common phenomenon in Francis turbines is draft tube surge. In these fixed-bladed machines, a strong runner outlet swirl can develop under off-design conditions. The action of the diffuser, and in particular the draft tube elbow, on the rotating flow fiel ...
Due to technological limitations robot actuators are often designed for specific tasks with narrow performance goals, whereas a wide range of output and behaviours is necessary for robots to operate autonomously in uncertain complex environments. We presen ...
Training for colonoscopy, which is the examination and treatment of the colon, is often performed on real patients once the physician has passed the novice level. This increases the risk to the patient and lengthens the procedure time. Since a decade ago, ...
This paper proposes and studies new strategies for an increase of the energetic efficiency of an urban transportation network fed with catenaries. A simulation tool has been developed to determine the energy efficiency on the global transportation system ( ...
The high-beta capability of the spherical tokamak, coupled with a suite of world-leading diagnostics on MAST, has facilitated significant improvements in the understanding of performance-limiting core instabilities in high performance plasmas. For instance ...
So far in the Twenty-first century the field of people transportation has had numerous setbacks, of these some are related to air pollution and some to the rarefaction of petroleum sources. Studies have been undertaken within this domain for many years now ...
