Reducing Moisture Transients in the Paper-Machine Drying Section with the Mid-ranging Control Technique

A new control strategy using feedback control has been developed for the multi-cylinder paper dryer configuration to reduce moisture transients in the drying section. The air system in the blow boxes was used to control the fast moisture transients in the paper machine. The new control system was combined with a previously developed physical model and was then compared with a conventional moisture

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
