74   Forward dynamics applied to a three-dimensional continuum-mechanical model of the upper limb Forward dynamics applied to a three-dimensional continuum-mechanical model of the upper limb Balaacute;zs Eacute;gert, Laacute;szloacute; Halpern and Ronald MacDonald    2011 This paper introduces, for the first time, a methodology to achieve a forward dynamics simulation of the musculoskeletal system using three-dimensional continuum-mechanical skeletal muscle models. This is achieved by coupling one- and three-dimensional skeletal muscle models. The feasibility of this methodology is demonstrated through a forward dynamics simulation of the upper limb involving the biceps and triceps muscle. (© 2011 Wiley-VCH Verlag GmbH & Co.

Labovschii    2005 A new space-marching technique is developed and shown to be robust and efficient for both internal and external flows. The new marching technique solves the coupled governing equations at two adjacent streamwise locations simultaneously, and the streamwise pressure gradient is discretized with central-differencing instead of the more usual forward-differencing in the marching direction. The governing equations are solved by marching either in the main flow direction or in the reverse direction, ... 查看全文

85   Reductions in Particulate and NOx Emissions by Diesel Engine Parameter Adjustments with HVO Fuel Reductions in Particulate and NOx Emissions by Diesel Engine Parameter Adjustments with HVO Fuel Matti Happonen*†, Juha Heikkilä†, Timo Murtonen‡, Kalle Lehto¶, Teemu Sarjovaara¶, Martti Larmi¶, Jo    2012 Hydrotreated vegetable oil (HVO) diesel fuel is a promising biofuel candidate that can complement or substitute traditional diesel fuel in engines. It has been already reported that by changing the fuel from conventional EN590 diesel to HVO decreases exhaust emissions. However, as the fuels have certain chemical and physical differences, it is clear that the full advantage of HVO cannot be realized unless the engine is optimized for the new fuel. In this article, we studied how much exhaust emis... 查看全文

Knight    2010 Scientific breakthroughs and basic research are frequently published in prestigious journals and praised for their impact. However, progress in clinical medicine is tedious and slow. There is still a distinct and even widening gap between basic science and clinical application. The dialog between basic science and clinical research has therefore to be intensified and a new culture of cooperation between basic and physician-scientists will become necessary to accelerate the transfer of new drugs ... 查看全文

91   Embedding limitations with audio-watermarking method based on cochlear delay characteristics Embedding limitations with audio-watermarking method based on cochlear delay characteristics    2009 We investigated embedding limitations with our proposed method of audio watermarking, which is based on the concept of embedding inaudible watermarks into an original sound by controlling its phase characteristics in relation to cochlear delay. We also improved the method by designing a parallel architecture for cochlear delay filters. We then evaluated our previous and improved methods to investigate embedding limitations by carrying out four objective experiments: LSD, PEAQ, bit-detection, and... 查看全文

93   On a Functional Equation in Finite Deformation† On a Functional Equation in Finite Deformation† Joseph E. Flaherty    2006 The finite deformation of a rectangular plate into a cylindrical shell gives rise to a functional equation whose general solution gives a variety of shapes into which the plate can be bent. Particular cases include the known forms which are circular, parabolic and one given by rn cos n θ = an, n = (3 – 2 σ)−1. The elliptic and hyperbolic forms are found possible only for incompressible plates. An incompressible plate can therefore be bent into a cylinder whose section is ... 查看全文
