This paper discusses prediction of the subjective response to walking sound - also called drum sound - based on differences in objective measurements. 'Walking sound' refers to the sound heard when someone is walking in the same room as the listener. Walking sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or la

Triad counts for directed graphs are represented as numerators of incomplete U-statistics with symmetric or asymmetric kernels. Asymptotic normality for the simultaneous distribution of all triad counts is proved. Applications are given to investigations of inconsistency in tournaments and reliability of communication networks.

After a long period of stagnation, Syria during the nineteenth century arose to a cultural and social renaissance. One important field of development was education. An article published in Beirut in 1883 sheds important light on this. External impulses were important, but much of the development effort was indigenous. There were significant differences in the level of education between towns and t

The theme of men and women is conspicuous in T. S. Eliot's early poetry. It constitutes the subject of this study, which is an investigation of the symbolic images, metaphors and similes associated with this theme. When a man/woman relationship is referred to, the relevant imagery is often taken from historical or mythical narratives, suggesting an element of universal applicability. Painful feeli

Retinitis pigmentosa (RP) is an inherited blinding disease for which there is no treatment available. It is characterized by a progressive and neurodegenerative loss of photoreceptors but the underlying mechanisms are poorly understood. Excessive activation of the enzyme poly(ADP-ribose) polymerase (PARP) has recently been shown to be involved in several neuropathologies. To investigate the possib

To explore the spatial variation of the soil microbial community within a mixed Norway spruce-birch stand, and to test if the spatial patterns of the microbial community are related to the position of trees, we sampled the forest floor at two spatial scales and used the phospholipid fatty acid (PLFA) patterns as indicators of the microbial community structure. Of the 32 most common PLFAs, 20 (62%)

Using a general 3-D finite-volume code, the development of buoyancy force driven secondary flow and its effects on developing laminar flow and heat transfer have been numerically simulated for a horizontal fuel cell duct with a rectangular cross section. The constant thermal-properties assumption except for linear density variation with temperature in the body force term is applied, and a constant

The use of bio-fuels is becoming more important because of the environmental benefits associated with these fuels. Deactivation of SCR catalysts applied in bio-fuel plants is a major problem due to the high potassium content of bio-fuels and therefore, great potential lies in finding regeneration processes that can be used commercially. Exposing the catalyst surface to sulphate groups generated by

Popular Abstract in Swedish En experimentell och teoretisk studie kring bränder i varulager i både modell och verklig skala har genomförts. Teoretiska modeller för att beräkna flamhöjder, gas temperaturer, gas hastigheter och värmeflöde inuti spalterna mellan de lagrade varorna presenteras. Modellerna kan t ex användas för att beräkna tid till utlösning av olika sprinklers som används för att skydA theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. Formulas for in-rack flame height, excess gas temperature, gas velocity and heat flux to storage walls are provided. The formulas include overall heat release rate,

OBJECTIVE: To follow the effect of a 4-month pelvic floor exercise (PFE) program in women with naïve urinary incontinence with vaginal electromyography (EMG), pressure and palpation and also to compare the initial findings with symptom-free women of the same age.METHODS: The pelvic floor function expressed with vaginal EMG, pressure and palpation was measured before, during and after 4 months of P

The thesis presents the author s research on numerical methods for Com-putational Aeroacoustics and the development of computational tools with direct applicability in industry. The designers in the gas-turbine industry, require accurate methods for predicting the onset and the frequencies of dangerous (pressure) oscillations, like the ones which typically occur in Lean Premixed Pre-vaporized (LPP
