A pending issue in linking ion mobility measurements to ion structures is that the collisional cross section (CCS, the measured structural parameter in ion mobility spectrometry) of an ion is strongly dependent upon the manner in which gas molecules effectively impinge on and are reemitted from ion surfaces (when modeling ions as fixed structures). To directly examine the gas molecule impingeme...
Battery-powered electric cars (BEVs) play a key role in future mobility scenarios. However, little is known about the environmental impacts of the production, use and disposal of the lithium ion (Li-ion) battery. This makes it difficult to compare the environmental impacts of BEVs with those of internal combustion engine cars (ICEVs). Consequently, a detailed lifecycle inventory of a Li-ion bat...
In a mobile environment. system and application performance is impacted by mobili ty factors such as varying bandwidt h. frequent disconnect ion, and changing locations. These factors make rnobility information more important in the design of distributed algorit hms. However, at present , no general mode1 exists for exploit ing the availability of mobility information. Focusing on this issue. t...
