Time-resolved quantum measurements using active detectors
(1998)Time-resolved quantum measurements using active detectors are analyzed. It is shown that the time-resolved observation of a quantum field leads to a mode mismatch between observed field and detection device that unavoidably ... -
Spontaneous parametric down-conversion for an arbitrary monochromatic pump beam
(1998)Signal-idler photon-pairs generated in spontaneous parametric down-conversion are considered for the case of an arbitrary monochromatic pump beam. It is shown that the quantum correlations between the signal and idler ... -
Synthesis of Fock states via beam splitters
(1997)An idea to synthesize Fock states for pulsed light beams is presented. It uses an array of beam splitters with several input ports which are fed with single-photon Fock states. Detectors survey all but one output port of ... -
Spontaneous emission from an extended wave packet : field correlations
(1996)Utilizing a recently found solution to the problem of a spontaneously radiating atom with an extended center-of-mass wave function [K. Rza̧żewski and W. Żakowicz, J. Phys. B 25, L319 (1992)] it is shown, for nonrelativistic ... -
FDiff3: a finite-difference solver for facilitating understanding of heat conduction and numerical analysis
(2004)The growing requirement for energy thrift and hence the increasing emphasis on ‘low-purchased-energy' designs are stimulating the need for more accurate insights into the thermal behaviours of buildings and their components. ... -
Quantifying acceptable mesh dependencies for computational investigations of airflows within rooms
(2002)Ignorance of mesh dependency can sometimes be an embarrassment in numerical calculations. Mesh structures need to be developed to eradicate mesh dependency without compromising the finite computing resource and/or incurring ... -
Use of computational fluid dynamics to aid studies of room air distribution: a review of some recent work
(2001)Computational fluid dynamics has a wide range of application in the study of room air distribution. The application is providing valuable guidance for those interested in such areas as comfort, productivity and sick building ... -
Behaviours of near two-dimensional ventilation configurations
(2002)Performances of eight configurations of a ventilated room are predicted. The flows exhibit increasingly three-dimensional tendencies as the proportion of wall occupied by the supply and extract vents is reduced. For all ... -
Influence of active heat sinks on fabric thermal storage in building mass
(2001)There is an increasing drive towards low energy architecture and developing buildings that work with the climate rather than in spite of it. One technology in the area of low energy building design is that of utilising ... -
A qualitative study exploring midwives' perceptions and views of extending their role to the examination of the newborn baby
(2003)Objectives: to explore midwives' attitudes and perceptions about extending their role to the examination of the newborn baby, as well as their general perceptions and attitudes to new role developments. Design: qualitative, ... -
Reflections on the research process: creativity and identity
(2002)This paper argues that we should better encourage our students to represent organisational life and their experience of it. Two options are discussed, the first one of which is to consider the adoption of a reflexive ... -
Searle and Collective Intentionality: The Self-defeating Nature of Internalism with respect to Social Facts
(2003)Several key elements go into Searle's construction of social reality, namely, collective intentionality, constitutive rules, and status functions. But by far the most important and arguably contentious of these is collective ... -
A new approach to time-domain vibration condition monitoring : gear tooth fatigue crack detection and identification by the Kolmogorov–Smirnov test
(2001)This paper introduces a new technique for early identification of spur gear tooth fatigue cracks, namely the Kolmogorov–Smirnov test. This test works on the null hypotheses that the cumulative density function (CDF) of a ... -
Gear condition monitoring by a new application of the Kolmogorov—Smirnov test
(2001)This paper introduces a new technique for the vibration condition monitoring of a set of spur gears. This technique, the Kolmogorov—Smirnov (KS) test, is based on a statistical comparison of two vibration signatures, which ... -
Implementing the EU accounting directives in Sweden — practitioners' views
(1999)Sweden legislated in 1995 to implement the European Union (EU) directives relating to harmonization of accounting. This article reports the results of an empirical study, based upon interviews and a questionnaire survey, ... -
The Development of Accounting Quality of IAS and IFRS over Time: The Case of Germany
(2009)We examine the characteristics of accounting amounts using a sample of German companies reporting under International Accounting Standards (IAS) during 2000-2002 (IAS period), and International Financial Reporting Standards ... -
Single-Particle Raman Spectrometer (SPaRS) for the non-destructive physico-chemical characterisation of aerosols
(2004)This project seeks to develop a prototype systems for the analysis of single levitated micrometre-sized particles captured from an ambient aerosol. The systems is designed to use Raman scattering to establish chemical ... -
Shape of a Co–Nd Liquid Alloy Ion Source
(1996)Co–Nd-liquid alloy ion sources (LAIS) were operated of a special specimen holder in situ in a 1 MeV transmission electron microscope. The dynamics of the tip shape in dependence of the ion emission current, spatial shifts ...
