Reduced transceiver-delay for OFDM systems

In this paper, it is shown that more than half of the data flow buffer, due to a bit reversed FFT output and cyclic prefix in an OFDM transceiver, can be removed. To achieve this, a new pipelined FFT processor is proposed and a cyclic suffix is used instead of the more commonly used cyclic prefix. The FFT processor is used either with a forward or backward data flow, i.e. performing either a decim

Water uptake by biomass burning aerosol at sub- and supersaturated conditions: closure studies and implications for the role of organics

We investigate the CCN activity of freshly emitted biomass burning particles and their hygroscopic growth at a relative humidity (RH) of 85%. The particles were produced in the Mainz combustion laboratory by controlled burning of various wood types. The water uptake at sub- and supersaturations is parameterized by the hygroscopicity parameter, κ (c.f. Petters and Kreidenweis, 2007). For the wood b

The Love and Hate of Bling Products: An industrial design student case

There are many different factors that influence our perception of products i.e. personal, product related and external factors. For designers to be able to address them all when creating new products, we need to deepen our understanding of the totality of perceptual experiences from non-instrumental interaction with products. One way of achieving this is by stimulating the creative process by util
