Effects of lattice reordering on Schnorr-Euchner decoding algorithms for MIMO systems

Schnorr-Euchner (SE) decoding algorithm for MIMO sys tems has been shown to approach the performance of Maximum-likelihood decoder with low complexity. There are two kinds of SE decoder, sequential SE and K-best SE. The lattice reordering, as the preprocessing of the SE de coder, is divided into four modes in this paper, according to post-detection signal-to-noise ratio (SNR) and channel noise lev

Prevalence of Lewy body dementia and neuroleptic treatment in nursing homes in Malmö, Sweden.

Background: Lewy body Dementia (LBD) is a well-known neurocognitive disorder in the elderly. The hallmarks of LBD are Parkinsonism without tremor, recurrent and persistent visual hallucinations often with insight, fluctuating cognition and alertness, rapid eye movement (REM) sleep behavior disorder with vivid dreams and violent movements, but relatively preserved memory functions. Nevertheless, LB

Behaviour of viscoelastic-viscoplastic spheres and cylinders—Fully plastic vessel walls

The material model consists of a viscoelastic Burgers element and an additional viscoplastic Bingham element when the effective stress exceeds the yield stress. For fully plastic vessel walls, exact closed-form expressions arc derived for the stress and strain state in pressurised or relaxation loaded thick-walled cylinders in plane strain and spheres. For the spherical problem, the material compr

A Stationary Turbine Interaction Model for Control of Wind Farms

Turbines operating in wind farms are coupled by the wind flow. This coupling results in limited power production and increased fatigue loads on turbines operating in the wake of other turbines. To operate wind farms cost effectively, it is important to understand and address these effects. In this paper, we derive a stationary model for turbine interaction. The model has a simple intuitive structu

The appropriate leader: A biographical-narrative reading of Matt 3.1–4.11

The influential scholar Ulrich Luz rejects the view of the Gospel of Matthew as an ancient biography, since he does not find any information about the education or the development of Jesus in the narrative from chapter 3. This conclusion does not give a fair description of neither ancient biographies in general nor the Gospel of Matthew in particular. Matthew actually picks up important themes in
