Particle content, radio-galaxy morphology and jet power : all radio-loud AGN are not equal
(2018-05-11)Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGNs) throughout cosmic time; however, there remain major uncertainties in translating radio ... -
Particle extinction measured at ambient conditions with differential optical absorption spectroscopy. 1 : System setup and characterization
(2005-03-20)We describe an instrument for measuring the particle extinction coefficient at ambient conditions in the spectral range from 270 to 1000 nm. It is based on a differential optical absorption spectroscopy (DOAS) system, which ... -
Particle extinction measured at ambient conditions with differential optical absorption spectroscopy. 2 : Closure study
(2006-04-01)Spectral particle extinction coefficients of atmospheric aerosols were measured with, to the best of our knowledge, a newly designed differential optical absorption spectroscopy (DOAS) instrument. A closure study was carried ... -
Particle habit imaging using incoherent light : a first step toward a novel instrument for cloud microphysics
(2011-04)The imaging unit of the novel cloud particle instrument Particle Habit Imaging and Polar Scattering (PHIPS) probe has been developed to image individual ice particles produced inside a large cloud chamber. The PHIPS produces ... -
Particle Image Velocimetry Measurement and Computational Fluid Dynamic Simulations of the Unsteady Flow within a Rotating Disk Cavity
(2014-05-16)In this article a combined experimental and numerical investigation of the unsteady mixing flow of the ingestion gas and rim sealing air inside a rotating disk cavity was carried out. A new test rig was set up, and the ... -
Particle image velocimetry measurement of in-cylinder flow in internal combustion engines : Experiment and flow structure analysis
(2002)A cross-correlation digital particle image velocimetry (PIV) system has been developed and applied to study the in-cylinder flow in a single-cylinder engine with a production-type cylinder head. The PIV system set-up and ... -
Particle Swarm Optimization Trained Artificial Neural Network to Control Shunt Active Power Filter Based on Multilevel Flying Capacitor Inverter
(2020-06-30)Shunt Active Power Filters (SAPF) are an emerging power electronics-based technology to mitigate harmonic and improve power quality in distribution grids. The SAPF proposed in this paper is based on three-phase Flying ... -
Particulate matter air pollution components and incidence of cancers of the stomach and the upper aerodigestive tract in the European Study of Cohorts of Air Pollution Effects (ESCAPE)
(2018-11-01)Introduction: Previous analysis from the large European multicentre ESCAPE study showed an association of ambient particulate matter <2.5 μm (PM2.5) air pollution exposure at residence with the incidence of gastric cancer. ... -
Partitional Clustering of Malware Using K-Means
(Springer Nature, 2014-05)This paper describes a novel method aiming to cluster datasets containing malware behavioural data. Our method transform the data into an standardised data matrix that can be used in any clustering algorithm, finds the ... -
Partnership working by default : district nurses and care home staff providing care for older people
(2005)Older people residents in care homes that only offer residential care rely on primary healthcare services for medical and nursing needs. Research has investigated the demands that care homes staff and residents make on ... -
Partnership working to benefit patients and the public: Benefits, challenges and recommendations from four projects
(2022-03-16)Partnership working involves two or more organisations working collaboratively to achieve a common goal. In England, partnership working between healthcare organisations and public library services is recommended to enable ... -
Partnership, Planning and Decision Making as Pre Conditions for Success of Social Marketing: a Case Study of Nutrition Cell Balochistan
(2019-03-28)This research is based on an agreed definition approved by the European Social Marketing Association (ESMA), Australian Association of Social Marketing (AASM), and the International Social Marketing Association (ISMA). It ... -

Pass Phrase Based Speaker Recognition for Authentication
(GI - Gesellschaft fur Informatik, 2003)Speaker recognition in applications of our daily lives is not yet in widespread use. In order for biometric technology to make sense for real-world authentication applications and be accepted by end users, convenience of ... -
Passing the buck : Corporate restructuring and the casualisation of employment
(2011-09-15)This article starts by looking critically at the contested concept of work flexibility, tracing the ambiguities inherent in it to the contradictions embodied in the 'special deals' struck between capital and labour in the ... -
Passive models of neurons in the deep cerebellar nuclei: the effect of reconstruction errors
(2004-06)The goal of this study was to determine how the fit of passive parameters in a compart-mental model varies depending on the precise morphological reconstruction of the neuron. We per-formed whole-cell recordings of deep ... -
The Past and Future of Evolutionary Economics : Some Reflections Based on New Bibliometric Evidence
(2016-06-20)The modern wave of ‘evolutionary economics’ was launched with the classic study by Richard Nelson and Sidney Winter (1982). This paper reports a broad bibliometric analysis of ‘evolutionary’ research in the disciplines of ...
