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
Approximately 30 kb of the mouse genome, containing the gene for a major seminal vesicle transcript, has been cloned. The gene was identified by the similarity to members of a family with rapidly evolving genes that includes the gene encoding the major clot protein in rat semen, SVS II, and the human semenogelin genes. The nucleotide sequence of 16.9 kb was determined; this sequence encompasses th
The two major primary degenerative dementias, dementia of Alzheimer type (DAT) and frontal lobe degeneration of non-Alzheimer type (FLD) have several clinical features in common but also many symptoms that differ. In a clinical material of 80 patients with either of the two forms of dementia (DAT = 39, FLD = 41) we have studied the levels of neuropeptides in the cerebrospinal fluid (CSF) in order
