Parallaxes of Five L Dwarfs with a Robotic Telescope
(2014-01-01)We report the parallax and proper motion of five L dwarfs obtained with observations from the robotic Liverpool Telescope. Our derived proper motions are consistent with published values and have considerably smaller errors. ... -
Parallaxes of L and T dwarfs

Parallaxes of southern extremely cool objects (PARSEC). II : Spectroscopic follow-up and parallaxes of 52 targets
(2013-12)We present near-infrared spectroscopy for 52 ultracool dwarfs, including two newly discovered late-M dwarfs, one new late-M subdwarf candidate, three new L, and four new T dwarfs. We also present parallaxes and proper ... -
Parallaxes of southern extremely cool objects III : 118 L and T dwarfs
(2018-12-11)We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multiepoch photometry of L and early T dwarfs. The observations were made on 108 nights over ... -
Parallaxes of southern extremely cool objects. I. : Targets, proper motions, and first results
(2011)We present results from the PARallaxes of Southern Extremely Cool objects ( PARSEC) program, an observational program begun in 2007 April to determine parallaxes for 122 L and 28 T southern hemisphere dwarfs using the Wide ... -
Parallel dynamic subcarrier and time allocation protocol for long-reach OFDMA-PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2015)A new advanced medium access control protocol is described to support 100 km reach access networks, exhibiting the required quality-of-service for next generation passive optical networks based on orthogonal frequency ... -
Parallel Image Encryption Algorithm Using Partitioned Cellular Automata on Graphic Processor Unit
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07-27)Image encryption is a reliable method for securely transmitting images over a network. The time required to encrypt and decrypt an image in online applications is also very important. Although cellular automata cryptography ... -
Parallel Microbial Ecology of Pasteuria and Nematode Species in Scottish soils
(2020-01-28)Pasteuria spp. are endospore forming bacteria which act as natural antagonists to many of the most economically significant plant parasitic nematodes (PPNs). Highly species-specific nematode suppression may be observed in ... -
A Parallel Pipelined Processor with Conditional Instruction Execution
(1991)In a recent paper by Smith, Lam and Horowitz [1] the concept of 'boosting' was introduced, where instructions from one of the possible instruction streams following a conditional branch were scheduled by the compiler for ... -
Parallel signal processing with S-Net
(2010)We argue that programming high-end stream-processing applications requires a form of coordination language that enables the designer to represent interactions between stream-processing functions asynchronously. We further ... -
Parallel Solution of Diffusion Equations using Laplace Transform Methods with Particular Reference to Black-Scholes Models of Financial Options
(University of Hertfordshire, 2014-07-22)Diffusion equations arise in areas such as fluid mechanics, cellular biology, weather forecasting, electronics, mechanical engineering, atomic physics, environmental science, medicine, etc. This dissertation considers ... -
Paramedic experiences of providing care in Wales (UK) during the 2020 COVID-19 pandemic (PECC-19): a qualitative study using evolved grounded theory
(2021-06)Objective: To explore paramedic experiences of providing care during the 2020 COVID-19 pandemic and develop theory in order to inform future policy and practice. Design: Qualitative study using constructivist evolved ... -
Parameter analysis of atomized droplets sprayed evaporation in flue gas flow
(2019-02-01)Spraying flue gas desulfurization (FGD) wastewater into the flue duct is a promising technology to achieve zero emission of wastewater by evaporation in thermal power plants. To deal with the scale and corrosion on flue ... -
Parameters for very light jets of cD galaxies
(2003-10-01)Recent Chandra X-ray observations of jets in central cluster galaxies show interesting features around the symmetry plane. We have carried out simulations involving bipolar jets, removing the artificial boundary condition ... -
Parametric analysis of influencing factors in Phase Change Material Wallboard (PCMW)
(2014-04-15)Incorporating Phase Change Materials (PCMs) into traditional building structures has been considered as an effective way to reduce the mismatch between energy supply and demand and in turn to minimise energy consumption ... -
Parametric analysis on the performance of a revolutionary rotary Ericsson heat pump/engine
(2019-03)A revolutionary mechanical heat pump/engine system utilizing the Ericsson thermodynamic cycle has been proposed to provide efficient and environmentally friendly cooling. Computer simulation models have been developed to ... -
