Policy Instruments for Energy Efficiency in Buildings: Experiences and Lessons from the Nordic Countries

The Nordic countries have often been seen as “fore-runners” of energy efficiency in buildings – in both the implementation of policy instruments and the evaluation of effects. Since the 1970s, the Nordic countries have introduced a range of policy instruments for energy conservation in buildings. The choice of instruments and experiences, however differs between countries. The aim of this study is

Identification of the current distribution on a radome from near-field measurements

Information about the equivalent current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to the equivalent current distribution is analyzed. The transformation is based on a singular value decomposition of the surface integral equation that relates the equivalent

A 3.3V low-jitter frequency synthesizer applied to fast Ethernet transceiver

A frequency synthesizer applied to 10/100 Base-T Ethernet transceiver is described. It can work in 10Mbps or 100Mbps mode adaptively and convert from one mode to another freely. The circuit can meet both requirements of transmitter on rising/falling time and receiver on CDR so that the additional power and area are saved. Under some testing circumstance, G of voltage control oscillator jittercycle

Design for cognitive assistance

In Sweden over the last twenty years, many people with developmental disabilities have chosen to move into their own apartments with different types of assistance. For most of them it has resulted in increased personal responsibility for household chores
