Designing products to fit human needs, preferences and capabilities is an essential key to competitiveness. In contested product markets, the management of user-related knowledge is therefore critical. Studies have shown that the identification and implementation of user requirements are significant issues for determining successful product development,(More)
As an important metal three-dimensional printing technology, electron beam melting (EBM) is gaining increasing attention due to its huge potential applications in aerospace and biomedical fields. EBM processing of Ti-6Al-4V as well as its microstructure and mechanical properties were extensively investigated. However, it is still lack of quantitative(More)
In tissue engineering, there is limited availability of a simple, fast and solvent-free process for fabricating micro-porous thin membrane scaffolds. This paper presents the first report of a novel surface suspension melt technique to fabricate a micro-porous thin membrane scaffolds without using any organic solvent. Briefly, a layer of polycaprolactone(More)
This paper will back-test the popular over-dispersed Poisson (ODP) bootstrap of the paid chain-ladder model, as detailed in England and Verrall (2002), using real data from hundreds of U.S. companies, spanning three decades. The results show that this model produces distributions that underestimate reserve risk. Therefore, we propose two methods to increase(More)
SUMMARY The average muscle activation for the major muscles such as rectus femoris (RF) and Gastrocnemius (GN) during running reveals that they need to exert higher muscle force without wearing compression garment. Previous evidences have shown that lower muscle activity at particular phases of gait cycle prolongs activity, reduces fatigue and reduces(More)
