During the last decade there has been a shift of focus from supply management towards demand management in logistics literature and practice. This article sets out to investigate what impact such a shift has on logistics, especially from a packaging perspective. An extensive literature review has been conducted, focusing on the top three journals in logistics as well as in operations management (J

This paper presents a low-complexity energy efficient channel pre-processing update scheme, targeting the emerging 3GPP long term evolution advanced (LTE-A) downlink. Upon channel matrix renewals, the number of explicit QR decompositions (QRD) and channel matrix inversions are reduced since only the upper triangular matrices R and R^-1 are updated, based on an on-line update decision mechanism. Th

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
