Despite the perceived role of retailers to realize corporate supply chain responsibility, retailers face a number of structural and managerial challenges to effectively influence the sustainability parameters in upstream supply chain. At the same time, research that touches upon implementation of sustainable sourcing by food retailers is limited leaving aside the inter-organisational managerial im
The stake holders seem to be pending on each others reaction towards ISA-systems (Intelligent Speed Adaptation). A situation can occur in which the car owners do not invest in the system because the car industry do not believe in it, the car industry waits upon the politicians’ standpoint, and the politicians leer at the public opinion… Decision makers need a good picture of what decisions are nee
This work presents an on-chip ground separation technique for power amplifiers. The ground separation technique is based on separating the grounds of the amplifier stages on the chip and thus any parasitic feedback paths are removed. Simulation and experimental results show that the technique makes the amplifier less sensitive to bondwire inductance, and consequently improves the stability and per
Statsmakterna kräver nu att verksamheterna vid Sveriges universitet och högskolor ska genomsyras av ett hållbarhetsperspektiv. Riksdagen har nu beslutat att dessa verksamheter ska ”främja en hållbar utveckling”. I regeringens Budgetproposition 2005/06:1 återfanns förslag till lag om ändring i högskolelagen. Där föreskrevs att 1 kap. 5 § högskolelagen (1992:1434) skall ha följande lydelse: Högskol
In order to qualify a subscriber loops for xDSL transmission, basic parameters like transfer function, scattering parameter S11 and characteristic impedance should be known. The aim of this paper is to present a test methodology for measurements of these basic parameters. The characteristic impedance is measured by open/short method and it is compared with the terminated measurement method defined
Wind turbines operating in wind farms are coupled by the wind flow. This coupling results in increased turbulence levels for downwind turbines, and consequently higher maintenance costs. In this paper, we consider a scenario where a wind farm is asked to produce less than maximum power. The objective is to minimize fatigue loads on the turbines, while maintaining the desired power production. We s
The story of Swedish waste management in the last forty years is the story of A farewell to landfills. This farewell is paramount to a happy-end tale of sustainability. “Sweden is today recycling 97% of its household waste” (Avfall Sverige, 2010) proudly tells that Sweden has opened an era of sustainable waste management. But is sustainability really so simple? Can there be another side to the sto
Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatme
We describe a scenario of independent TV programme dissemination where viewers receive their own tailored channel created from content in which they’re interested. We focus primarily on the problem of distributing the content from the producers to all interested viewers. Our approach is based on a multicast scheme called implicit group messaging, realised as a distributed structured peer-to-peer n
