Indoor temperature is by measurements stated to rise 0.1 – 0.2°C per storey upwards in multi-storey buildings, despite occupants’ possibility to control the temperature. Due to upward air temperature gradient in rooms there will be a heat transfer through slabs upwards. The size of this depends on insulation degree of building envelope and slabs and air flow through the building. With a linear mat

Abstract in UndeterminedThis paper presents an inductorless ultra-low power radio receiver front-end intended for applications such as sensor networks and medical implants. It consists of low noise amplifier, quadrature mixer, and a frequency divider for the generation of quadrature local oscillator signals. The power consumption is just 282μW from a 0.9V supply when it operates in the 915 MHz ISM

Den ekonomiska krisen borde öka benägenheten att ansluta sig till facket, men medlemmarna sviker och störst är raset hos hotell- och restauranganställda. Anders Kjellberg är docent i sociologi och forskar vid Lunds universitet kring facklig anslutning. - Mellan 2006 och 2008 sjönk fackanslutningen från 77% till 71%. Hade det inte varit för lågkonjunkturen hade raset varit ännu större, säger Kjellb

This paper presents a methodology to reduce the power consumption, by using multiple supply voltage levels. The voltage levels are scaled down from a single supply voltage, by the use of a diode-connected device. Only one single device is used per conversion, which gives a small area overhead. No inductors and no off-chip components are used. The methodology is tested on different constellations o

Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we propose two improvements to a recently proposed framework based on global optimization. The mesh geometry is analyzed both from a theoretical and experimental viewpoint and hexagonal meshes are shown to be superior. Our se

Robotised welding is one of the most important robot tasks used in manufacturing industry. The operator usually performs the programming of the robot manually, i.e. by jogging the robot arm to each coordinate pose in space. Programming can, however, be made more accurate by the use of simulation, using so called Computer Aided Robotics. Simulation can also be a powerful tool to evaluate and contro
