Underwater autonomous manipulation is a challenging task which not only includes a complicated multibody dynamic and hydro-dynamic process, but also involves the limited observation environment. This paper is proposed to investigate the current state of art about underwater autonomous technology. Although a lot of research aiming at autonomous under-water vehicle manipulator system (UVMS) of large-scale...
This article presents a comprehensive review on a non-invasive, high resolution and high contrast imaging modality, called thermoacoustic tomography (TAT). Details about the principles, history and future directions of TAT are described.
Since the shortage of spectrum resources, paper raises a improvement based on the user waiting time and bandwidth requirement of CSGC algorithm via the analysis of graph coloring model. The new algorithm takes into account both user waiting time and actual bandwidth requirements, so that minimize the total unsatisfied needs and users tend to equal access to spectrum resources. It ensures the fairness...
A series of ruthenium substituted polyoxotungstates were used to catalyze the cleavage oxidation of styrene. Under all experimental conditions investigated, reaction products were benzaldehyde and benzoic acid. Kinetic studies showed that these reactions were consecutive reactions consisting of first oxidizing styrene into benzaldehyde and then oxidizing the benzaldehyde into benzoic acid. In this...
