Popular Abstract in Swedish Demens med Lewy bodies - en ny demenssjukdom Vid sidan av de klassiska demensformerna Alzheimers sjukdom, blodkärlsdemens och frontallobsdemens har forskargrupper från flera håll i världen på senare år funnit tecken på en ny demensform som man kallar ”demens med Lewy bodies (DLB)”. Sjukdomen bär drag av både Alzheimers och Parkinsons sjukdom och därför är forskare oeniDementia with Lewy bodies (DLB) is a dementia disorder, clinically characterized by fluctuating cognitive impairment, attention deficits, visual hallucinations, parkinsonism and other neuropsychiatric features. Sensitivity to neuroleptic medication is a common finding. In the present study 24% of 200 autopsied cases, within the Lund longitudinal prospective dementia study fulfilled the clinical di

This paper presents a highly parallelized MIMO signal detection algorithm targeting vector-based reconfigurable architectures. The detector achieves high data-level parallelism and near-ML performance by adopting a vector-architecture-friendly technique - parallel node perturbation. To further reduce the computational complexity, imbalanced node and successive partial node expansion schemes in con

We consider the problem of constructing linear precoders for quasi-stationary multiple-input multiple-output channels. We assume maximum-likelihood detection and the objective of the precoding is to maximize the minimum Euclidean distance of the signaling. Since the channel remains constant for some time, the precoding can be performed spatially as well as in time. As will be shown, the precoder d

Popular Abstract in Swedish Ämnet hållfasthetslära behandlar metoder och principer för att kunna bestämma deformationer och spänningar i en fast kropp som utsätts för belastning. Avhandlingen behandlar skademekanik, vilket rör hur skador (porer, håligheter, mikrosprickor och dylikt) påverkar materialets egenskaper och hur skadorna påverkas av belastning. Vidare förutsätter skademekaniken att materPlasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. The undesired property that, irrespectively of the postulate emp
