Astronauts spend much time training to control the robotic arm aboard the International Space Station, and must perform a variety of challenging, three-dimensional tasks. They use a unique, bimanual control system to control ...

Microfluidic affinity-based cell capture devices are presently able to isolate specific cell populations from heterogeneous samples, such as whole blood. The impact of this potentially powerful technology, however, is ...

There has been much effort to characterize and model coal for use in combustion and gasification. This work seeks to delineate the differences and similarities between biomass and coal, with emphasis on the state of the ...

The biologically inspired method of tail articulation is investigated as a means of reducing tonal noise due to the stator wake blade interaction in underwater vehicles. This work is experimental in nature and conducted ...

Blind puncture access procedures are frequent in medicine but can lead to complications due to over-puncture. When tissue membranes yield under applied stress, the device suddenly accelerates forward into the patient. ...

Quorum sensing is a decentralized biological process, by which a community of bacterial cells with no global awareness can coordinate their functional behaviors based only on local decision and cell-medium interaction. ...

Buildings are one of the world's largest consumers of energy, yet measures to reduce energy consumption are often ignored during the building design process. In developing countries, enormous numbers of new residential ...
