In recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ILs) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. Sonic speed is an important thermodynamic property of ionic liquids (ILs) and always chosen as a source to determine other properties. A database for the sonic speed of pure ILs cre...

With the development of service robots and with the emerging concept of the ubiquitous world, localization of a mobile robot has become a popular issue. Even though several localization schemes have been previously, none of them is free from the economical constraints placed on commercial robots. To implement a real time commercial localization system, a new absolute position estimation method ...

Mass deposition fluxes of mineral dust to the tropical northeast Atlantic Ocean were determined within this study. In the framework of SOPRAN (Surface Ocean Processes in the Anthropocene), the interaction between the atmosphere and the ocean in terms of material exchange were investigated at the Cape Verde atmospheric observatory (CVAO) on the island Sao Vicente for January 2009. Five different...
