A statistical method for parameter estimation from Schroeder decay curves

The sound decay curve, measured by either the interrupted noise method or the Schroeder method, can provide relevant information pertaining to a room’s acoustical properties. However, the relevant information is not always readily extractable from the measurements. In this study, measurements of the decay curves of the historically important Vadstena Abbey church in Sweden have been obtained using

Pygmy resonances: what's in a name?

The centroid, width and percentage of energy weighted sum rule of dipole resonances can be strongly affected by dynamical fluctuations and static deformations of the nuclear surface, deformations and fluctuations which, in turn, depend on pairing, and thus on Cooper pairs. Because of angular momentum conservation, such insight is restricted, to lowest order, to fluctuations/deformations of quadrup

Modelling tool life in high speed machining of AD730

AD730® is a new type of nickel-based superalloy, developed by Aubert & Duval, with high temperature properties exceeding conventional superalloys such as Alloy 718. This paper presents the tool life model for this superalloy for the purpose of process optimization and manufacturing cost estimation. The tool life modelling is based on comprehensive machining tests, using the Colding model. The

Beyond Ethnographic Representation

This chapter deals with ways in which digital technologies can be utilized to work with moving media in hybrid ways. It will resonate with practices of ethnographic film, but it will also attempt to move beyond traditional, representational notions of this practice, very much in line with the ideas of the “new world of ethnographic film and video” that Phillip Vannini outlines in the introduction

Diffraction, Good-Walker, and the BFKL pomeron

The proton has a substructure in terms of parton cascades, which in a high energy collision fills the whole rapidity range between projectile and target. In the Good–Walker formalism the fluctuations in the cascades will give rise to diffractive excitation. Within the Lund Dipole Cascade model, it is in this way possible to reproduce diffractive excitation in pp collisions and DIS. In central pp c

Innovative solutions for good daylighting and low energy use in multi-family dwellings: MKB Greenhouse, Malmö, Sweden

This is the report of the work for project Dagsljuskrav i miljöcertifierade byggnader" of the Swedish Energy Agency, project number: 39682-1. The study was focused on the energy use and daylight conditions in the multi-family building Greenhouse located in Malmö, Sweden. The aim of the study was first to analyze and develop innovative design solutions for multi-family dwellings with good daylighti

Daylight utilization in buildings : Analysis of existing conditions and development of improved rules and metrics

This is the report of the work carried out for project "Dagsljusanvändning i byggnader" of the Swedish Energy Agency, project number 41816-1. This research provides background scientific information on the daylight performance of multi family apartment blocks located in Stockholm, and Örebro, Sweden. A sample of 54 buildings that consist of 10 888 individual rooms was evaluated using advanced dayl

Glycosaminoglycans: a link between development and regeneration in the lung : a link between development and regeneration in the lung

What can we learn from embryogenesis to increase our understanding of how regeneration of damaged adult lung tissue could be induced in serious lung diseases such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and asthma? The local tissue niche determines events in both embryogenesis and repair of the adult lung. Important constituents of the niche are extrace

Recombinant dermatan sulfate is a potent activator of heparin cofactor II-dependent inhibition of thrombin

The glycosaminoglycan dermatan sulfate (DS) is a well-known activator of heparin cofactor II-dependent inactivation of thrombin. In contrast to heparin, dermatan sulfate has never been prepared recombinantly from material of non-animal origin. Here we report on the enzymatic synthesis of structurally well-defined DS with high anticoagulant activity. Using a microbial K4 polysaccharide and the reco
