Multiscale detection of transient evoked otoacoustic emissions

This paper presents a unified approach to multiscale detection of transient evoked otoacoustic emissions (TEOAEs). Using statistical detection theory, it is shown that the optimal detector involves a time windowing operation where the window can be estimated from ensemble correlation information. The detector performs adaptive splitting of the signal into different frequency bands using either wav

Diagnostic accuracy of the neurological upper limb examination II: Relation to symptoms of patterns of findings

Background: In a sample of patients in clinical occupational medicine we have demonstrated that an upper limb neurological examination can reliably identify patterns of findings suggesting upper limb focal neuropathies. This further study aimed at approaching the diagnostic accuracy of the examination. Methods: 82 limbs were semi-quantitatively assessed by two blinded examiners ( strength in 14 in

Optical dating of young tidal sediments in the Danish Wadden Sea

We have tested the applicability of optically stimulated luminescence (OSL) to the dating of young estuarine sediments (< 1000 years) to determine whether this method can be used to complement and support existing techniques, such as Pb-210 dating. The degree of bleaching before deposition is investigated by examining the age trend in various sediment cores, and where possible, by comparison with

Korttidspsykoterapi med kvinnor och män i samband med graviditet och nyföddhetsperiod

Korttidspsykoterapi med sex kvinnor och sex män i samband med graviditets- och post partumperioden analyserades med narrativ ansats och med anknytningsteori och affektteori som grund. Syftet med studien var att skaffa kunskap om psykiska besvär hos blivande och nyblivna föräldrar och att undersöka om korttidspsykoterapi med kvinnor och män i samband med barnafödandet i förebyggande syfte kunde avl

VUV spectroscopy of pure and Sm2+ doped SrFCl crystals

The creation and relaxation of electronic excitations in pure crystalline SrFCl and Sm2+ doped SrFCl were investigated using vacuum ultraviolet (VUV) spectroscopic methods. In the emission spectra of pure SrFCl and SrFCl: Sm2+ a strong emission band in the vicinity of 4.7 eV was detected, connected to self-trapped exciton (STE) having a Cl-2(-) core. The threshold for creation of STE was detected

Migration of model contaminants from PET bottles: influence of temperature, food simulant and functional barrier

To simulate post-consumer recycled plastics, selected model contaminants were incorporated into PET bottles using a time saving method. Migration into 3% acetic acid, a cola-type beverage and 95% ethanol was followed during 1 year of storage at 20 and 40degreesC. Aroma compounds previously found in post-consumer PET material were used as model contaminants. Benzaldehyde was found to migrate to the

Colloidal fouling during ultrafiltration

Colloidal fouling causes serious problems in many membrane plants. Two different kinds of flux-reducing phenomena occur when treating colloidal dispersions, When treating stable dispersions the flux is reversible and can be restored after changing the operating parameters, such as the transmembrane pressure or the crossflow velocity. The flux reduction experienced when treating unstable colloidal

Analysis of dynamic reservation schemes for cellular networks

Out of Quality of Service reasons, higher priority shall in cellular networks be assigned to ongoing connections than to new call attempts. In order to improve the efficiency of the bandwidth reservation scheme, the amount of bandwidth to reserve for high priority connections can be made time-varying and adaptive towards the momentary network conditions. Subscriber movement predictions can be appl

Bicycle Dynamics and Control

In this paper, the dynamics of bicycles is analyzed from the perspective of control. Models of different complexity are presented, starting with simple ones and ending with more realistic models generated from multibody software. Models that capture essential behavior such as self-stabilization as well as models that demonstrate difficulties with rear wheel steering are considered. Experiences usi

Industrial Management Models with Emphasis on Construction Waste

Popular Abstract in Swedish Avfallshantering ägnas nuförtiden ett ökande intresse. Detta verk syftar till att analysera hur vanligt förekommande företagsekonomiska modeller och metoder liksom principen om att förorenaren betalar (The "Polluter-Pays Principle" (PPP)), generellt kan appliceras på management av avfallshantering och specifikt på segregering av olika avfallsfraktioner i syfte att medgeIncreased attention is nowadays devoted to waste management. The objective of this work is to analyse how commonly known business economic models and methods, as well as the Polluter-Pays Principle, can be applied to waste management in general and to waste fractionation in particular, so as to facilitate environmental optimisation of industrial and construction waste fractionation. In discussing
