Spatial Sound With Loudspeakers and Its Perception: A Review of the Current State

Abstract: This paper reviews the current state of loudspeaker-based spatial sound reproduction methods from technical perspective as well as perceptual perspective. A nomenclature is developed that allows for a strict separation between these two perspectives. The physical fundamentals, practical realization, and results from perceptual studies are discussed for a number of well-established and emerging reproduction techniques. Further, the paper outlines novel approaches to spatial sound evaluation in terms of perceived quality and provides a comparison of current approaches.

Patient perspective of systemic lupus erythematosus in relation to health-related quality of life concepts - a qualitative study

Abstract: We sought to understand the patients' 'lived experiences of systemic lupus erythematosus (SLE)' by exploring, describing and clarifying the patients' perspective of how they felt about having SLE and how the disease impacted on their lives, both positively and/or negatively. An interpretative phenomenological approach was employed. Semi-structured interviews were undertaken with 30 females with SLE across a wide range of age (21 to 75 years), disease characteristics, disease duration (1 to 28 years) and ethnicity (Whites, South Asians). Eleven themes emerged as important to the patients: prognosis and course of disease; body image; effects of treatment; emotional difficulties; inability to plan due to disease unpredictability; fatigue; pain; career prospects and loss of income; memory loss/concentration; reliance on others to assist with everyday tasks; and pregnancy issues. Most patients reported a negative impact of SLE on their lives although a few patients found positive aspects to having SLE. The findings of this study identified themes important to patients with SLE and these themes will inform clinicians on the patients' perspective of having SLE.

GANDOLF: a system for generating automated nowcasts of convective precipitation

Abstract: During the past decade hydrologists have become increasingly aware of the problems of fluvial flood prediction during periods of intense convection, particularly in urbanised catchments whose rainfall-runoff responses tend to be rapid. Existing approaches to deterministic, short-range rainfall prediction are often deficient in their treatment of convective precipitation because they cannot resolve individual convective clouds or effectively model their evolution. In 1994 the UK Met. Office established a joint R&D programme with the Environment Agency (responsible for flood prediction in England and Wales) to explore the benefits of an Object-Oriented conceptual Model (OOM) of convection in the nowcasting of fluvial floods. This involved the development of an automated nowcasting system (GANDOLF) designed to run the OOM during episodes of air mass convection. This paper describes the structure and function of the GANDOLF system and compares the performance of the OOM with that of two other precipitation models routinely used by Thames Region of the Agency.

The role of electrostatic and hydrodynamic forces in the negative-point breakdown of liquid dielectrics

Abstract: By combining simple electrostatic and hydrodynamic concepts one can derive equations for cavity growth, the instability growth rate, and streamer velocity, with results in reasonable agreement with experiments at voltages near breakdown, in short gaps. In high-viscosity fluids other hydrodynamic growth processes are observed. Thus in 100 and 1000 cSt DC-200 silicone fluids a vortex of hot liquid forms near the point cathode and this vortex develops into a vortex ring which grows and decays; at high fields the vortex undergoes an unstable growth process, leading to multiple vortices. >
