The paper questions the notion that the diffusion of electronic commerce will lead to disintermediation. Rather than interpreting intermediation as a single service it is pointed out that intermediaries can provide a number of services. The analysis based on the New Institutional Economics, Market Microstructure Theory, and Information Economics shows that(More)
This paper questions the widely held view that B2C eCommerce markets are characterised by a high intensity of competition, using a mixture of theoretical arguments and empirical evidence. We discuss two hypothesis and survey empirical studies which test them. We argue that the goods sold in B2C eCommerce have to be interpreted as heterogeneous " composite(More)

In this paper an improved method for designing electric propulsion systems consisting of e-machine and inverter, based on a co-simulation, is presented. As the mandated emission limits of vehicles are expected to become stricter, advanced design methods are necessary to calculate accurate losses of machine and inverter. The approach contains the influence(More)
Taking into account typical power and temperature requirements of electric vehicle applications, silicon carbide based semiconductor devices seem to be the most promising candidates for future high power density traction inverter applications. Therefore, the design of a three-phase DC-AC inverter based on SiC MOSFETs under automotive constraints is(More)
