We find the Shannon limit to bit error rate (BER) as a function of E_b/N_0 for linear coded modulations. Error performance of TCM and other schemes can be compared to this curve. As the bandwidth of the signals in Hz-s/data bit drops, capacity becomes sensitive to the stopband spectrum, and the limit moves strongly away from the BER of practical systems when the stopband rolloff is not severe.
BACKGROUND: Post-surgery thigh edema, loss of knee-extension strength, and reduced physical performance are common following a hip fracture. It is not known if knee-extension strength and physical performance are related to the edema and fracture type. The aim of this study was to examine the influence of fracture type and post-surgery edema on physical performances in patients with hip fracture.
In this position paper we present methodological considerations from a project in which we have collaborated with people with cognitive difficulties and university students. For people with considerable difficulties in communicating, a new means of expressing their dreams was required. Cultural probes were used to inspire, inform and surprise in the design process: situated probing.
It has been acknowledged that the shift to more sustainable consumption patterns and levels is a complex task that requires the involvement of multiple societal actors and clear visions of more sustainable lifestyles. In addition to the complex nature of the problem and the diversity of interest of different actors with regard to their role in facilitating the change, there are also a number of my
