With increasing usage of the Internet, energy consumption of network equipment has become a crucial challenge from both an economic and an environmental point of view. This paper combines users’ behavior of accessing the network with energy saving algorithms for energy-aware network equipment, and investigates potential energy savings in the access network. The study is based on a set of traffic d

The substitution in varying amounts of strontium (Sr) for calcium in the alpha tricalcium phosphate (α TCP) structure was investigated. The effects on the reactivity towards the formation of hydroxypalatite on hydration were also studied. The prepared α-TCP and the fully hydrated α-TCP powders were characterized by means of X-ray diffraction and the CuKα1 radiation. It was found that the alpha for
This chapter highlights the general theme of the book, including definitions of defense mechanisms within various theoretical frames of reference. After a period of exclusion from mainstream clinical psychology the concept of defense has now returned to center stage.
This paper presents a new real-time architecture for motion control of industrial robots. The new control system obtained has two main advantages: first it provides a total open control architecture and the second advantage is the simplicity and the interactivity of the platform developed. Experimental evaluation of a passivity-based control scheme shows the benefits of the architecture which is u
Consumers are increasingly taking an interest in how their food is produced. Concerns are being voiced that practices that are environmentally harmful, involve maltreatment of animals or exploit poor and vulnerable farmers, should be avoided. The term societal concern has been coined for concerns that are derived from broadly shared values within a society, often entailing an ethical dimension. Th
Hur påverkar BRYT-projekt deltagarnas syn på utbildning och arbetsliv? Förbättras möjligheterna på arbetsmarknaden för dem som väljer könsöverskridande? Frågorna behandlas i uppföljningen av 21 kvinnor som deltog i en teknikkurs riktad till långtidsarbetslösa kvinnor med arbetshandikapp. Resultaten visar att nästan hälften av deltagarna valde att utbilda sig till yrken inom mansdominerade bransche
The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely
In this paper we evaluate the use of parallel interleavers for user separation in coded IDMA systems. The parallel interleavers have previously been evaluated for uncoded systems, and we here present extended results for the coded case. The new results are important for real systems, as they will most likely use performance enhancing channel coding. The parallel interleavers are designed to remove
The aims of the studies in the thesis were; 1.to investigate incidence, risk factors in comparison to non lacunar stroke patients, initial course and long term prognosis in pure motor stroke (PMS) 2.to determine topography and most probable pathogenetic mechanism of lesions in sensorimotor stroke (SMS). 3.to study if diffusion weighted magnetic resonance tomography(DWI) contribute to a more precis
