Abstract What happens if you put assistive robots in the hands of old adults? Will they accept or reject the robot? If they accept the robot, in which ways will the robot change the everyday lives of old adults? Old adults have a lifetime of experience technological changes. Seniors have adopted as well as rejected new technological advances in the past. If domestic assistive robots are adopted an
Morocco has for twenty years been in what is officially described as a transition to democracy. During the former king Hassan II negotiations with the opposition resulted in two constitutional reforms and a new government in 1998 dominated by the former opposition parties. In the 2000s two important law reforms were made: a new law of personal status in 2004 and a new constitution in 2011. The new
This paper presents an improved synthetic loading method to measure the performance of an interior permanent magnet synchronous machine (IPMSM). A complete analysis of torque-, flux-, and efficiency-maps are done by means of a vector controlled drive implemented with in a field programmable gate array (FPGA). The measurements are compared to results from Finite Element Analysis (FEA). A key featur
An adaptive controller consisting of a real time identifier and a minimum variance regulator is discussed. The identification is done by augmenting the state with the unknown parameters of the process. This usually leads to a non-linear filtering problem. By choosing a model of special structure the problem can, however, be reduced to a linear problem. The control law is derived using stochastic o
The Cellular Neural Network provides an interesting template for non-linear signal processing. It is essentially based on 2nd-order (reaction / diffusion) differential equations. Harrer and Nossek have introduced the discrete-time equivalent that paves the ground for digital implementation. The interconnect requirements seem to have made it impossible to realistically implement this model. More th
Popular Abstract in English The conventional approach to the analysis of structural change is to apply a horizontal perspective on the economy. This means that sectors are studied in isolation. By the integration of two strands of literature on structural change and the role of technology, evolutionary economics and input-output economics, this thesis applies a vertical perspective on the economy This thesis analyses structural changes and the role of technology in the Swedish economy since the 1970s. With the attention directed towards interdependencies between sectors, a vertical perspective is applied on the economy. This contrats to the most often used horizontal perspective, in which individual sectors, such as manufacturing and services, are studied in isolation. With an integration

Both within Europe and Sweden energy requirements gradually are becoming more stringent in order to increase the share of new buildings with low energy use. However, if the construction and property owners sectors shall make decisions, about larger investments within the field of low energy buildings, a complete evaluation of the buildings´ performance after a few years of operation is needed. Acc
A 7th order polyphase G/sub -m/C IF filter with automatic frequency tuning, implemented in a 0.35/spl mu/m CMOS process, is presented. The filter has a center frequency of 3MHz and a passband of 1MHz. The image band rejection is higher than 57dB, the stop band attenuation is at least 40dB. The in-band spurious free dynamic range is around 53dB. On-chip automatic frequency tuning provides more than
