Abstract: Directional acoustic cloaks that conceal an aluminum cylinder for airborne sound waves are presented in this paper. Subwavelength cylindrical aluminum inclusions in air constitute the cloak design to aid practical realizations. ...

Abstract: An experimental study of a bottom-burning oil shale retort is described. It is shown that for a constant oxidizer flow the combustion front moves at a uniform velocity through the bed. This ...

Abstract: The heat transfer to a single cylindrical sample of oil shale in a staggered tube bundle was studied both numerically and experimentally in order to evaluate the thermal and chemical processes ...

Abstract: Direct contact binary cycles may be used to develop electrical power from moderate temperature geothermal brines. For a simple Rankine cycle using direct contact heat exchangers isobutane is ...

Abstract: A procedure has been developed for calculating the work performed by the left ventricle during the heartbeat. This procedure involves the continuous direct measurement of fluid mixture temperature ...

Abstract: An explicit procedure for analyzing a superheated, evaporating lens direct contact heat exchanger has been developed. This method is based upon the application of a dimensional analysis derivation ...

Abstract: Although it is well accepted that bone tissue metabolism is regulated by external mechanical loads, it remains unclear to what load-induced physical signals bone cells respond. In this study, ...

Abstract: As a step towards developing a finite element model of the knee that can be used to study how the variables associated with a meniscal replacement affect tibio-femoral contact, the goals of ...
