Title: Development of novel low noise Switch-mode power supply designs for high fidelity audio power amplifiers

Time: 2:00PM-3:00PM

Date: Wednesday 25 February 2015

Room: P335, Poole House, Talbot Campus

 

Abstract:

Nowadays, linear power supplies are widely used to provide the supply voltage rail to an audio amplifier and are considered bulky, inefficient and expensive due to the presence of various components. In particular, the typical requirements of linear designs call for physically large mains transformers, energy storage/filtering inductors and capacitors. This imposes a practical limit to the reduction of size and weight in audio power systems. In order to overcome these problems, Switch-mode Power Supplies (SMPS) incorporate high speed switching transistors that allow for much smaller power conversion and energy storage components to be employed. In addition the low power dissipation of the transistors in the saturated and off states results in higher efficiency, improved voltage regulation and excellent power factor ratings. However, the use of SMPS in audio amplification is not novel in itself, the contribution will arise from design optimisation to achieve the lowest possible harmonic distortion in the audio output stage. Therefore, the primary aim of this research project is to develop the novel low noise switch mode power supply for an audio power amplifier. It will also strive to elevate the reliability of SMPS through stability analysis and enhance the efficiency of power supply through high speed switching transistors. As a result, the research will aim towards changing the way industrial manufacturing of power supplies for audio amplifiers are carried out. It will also provide a new path for researchers in this field to utilize the SMPS in all other audio devices by further enhancing its efficiency and reducing system noise.

 

We hope to see you there.

 

Cloud and Weather Simulation for computer graphics

We would like to invite you to the next research seminar of the Creative Technology Research Centre.

 

Speaker: Leigh McLoughlin

Title: Cloud and Weather Simulation for Computer Graphics

Time: 2:00PM-3:00PM

Date: Wednesday 18th February 2015

Room: P335, Poole House, Talbot Campus

 

Abstract:

In this talk I will discuss my work on cloud simulation for computer graphics. This work was designed to provide a means of simulating clouds and weather features, such as rain, using desktop graphics hardware. This involves elements of meteorology, numerical weather simulation and computational fluid dynamics, taken from the sciences and adapted to meet the more artistic requirements of computer graphics in which an element of control is required and the laws of physics may be wilfully disobeyed. The result is a lightweight physically-inspired cloud simulation scheme, capable of emulating the dynamic properties of cloud formation and weather effects.

We hope to see you there.

The editor is a *!@#*!

Editors of academic journals are regularly cursed by academics worldwide.  At universities across the globe we can regularly hear expression such as “Who does the editor think he is rejecting my paper?” or “Why does it have to take six months (or more) to find out my paper is rejected?” or “Why does the editor not understand how good/novel/innovative/… our paper is?  These kinds of expression of dismay may or may not be accompanied by an expletive.  Being both busy editors and well published authors we thought timely to put pen to paper and explain the work (role and limitations) of the typical editor of an international academic journal.

First, being an editor is not all bad, and is actually a privilege. It is an opportunity to nurture new authors, be at the forefront of your discipline and it is part of being a ‘serious’ scholar. However, we have been at the receiving end of the wrath of authors dissatisfied with something we did or didn’t do as an editor AND we have been disappointed as authors with what we perceived to be, poor editorial decisions!

We wrote a short outline of the proposed paper and send it to the editor of Women and Birth.  The idea was readily accepted and resulted in a paper published this week in the scientific journal.

The paper includes little snippets of insight and advice to authors.  For example, a reminder that the average editor of an academic journalist an unpaid volunteer, usually a full-time lecturer and/or researcher with a busy day job, who does most of her editorial work on Sunday morning when the kids are still in bed or Tuesday night after the second-year marking has been completed. We hope that knowledge of the editors’ role will help authors (a) understand the submission process better; and (b) be a little bit more patience with the editors.  And, last but not least, we hope our article helps the development of editors of the future.

Most cited article in MIDWIFERY

The scientific paper ‘Risk, Theory, Social & Medical Models: a critical analysis of the concept of risk in maternity care’ written by Dr. Helen MacKenzie Bryers (NHS Highland) and BU Professor of Reproductive Health Research is now listed on the website of the international journal Midwifery  as its top most cited paper since 2010 (1).   Midwifery, published by Elsevier, is one of the leading global journals in the field of midwifery and maternity care.

The paper provides a critical analysis of the risk concept, its development in modern society in general and UK maternity services in particular. Through the associated theory, the authors explore the origins of the current preoccupation with risk.  Using Pickstone’s historical phases of modern health care, the paper explores the way maternity services changed from a social to a medical model over the twentieth century and suggests that the risk agenda was part of this process.

‘Risk, Theory, Social & Medical Models’ has been cited 40 times in SCOPUS, measured today Jan. 25th 2015.   In Google Scholar the citation rate is even higher  and stands at 69.

First BU publication of 2015

Those working in the reproductive health field or in local media will be familiar with the phenomenon of the reporting of the first baby born in the New Year.   For example, you may have read a short item of the first baby of 2015 born just after midnight with a lovely picture of the baby with proud parents and/or midwife.

 

This BU Research Blog is the equivalent of the first publication for 2015.  I contributed a chapter called ‘Sociology of Midwifery’ to the edited book Sociology for Midwives published by Polity Press (Jan. 2015) and edited by Ruth Deery, Elaine Denny & Gayle Letherby.

The Polity Press website lists three reviews of the book by eminent academics in the field of midwifery:

“What is the point of sociology for midwives and midwifery? A sociological perspective can give us a different understanding of reproduction and maternity care. It can help us challenge our ‘common sense’ assumptions about how people and the world tick. This new book provides midwives and midwifery students with a readable comprehensive and up to date review of the field of sociology applied to reproduction and maternity care. The editors bring together a very impressive amount of material and present it in an accessible and clear way. Their facility for handling complex theoretical and detailed empirical material is admirable.”

Jane Sandall, King’s College London

 

“The editors and authors of this fine volume have produced a wonderful introduction to the value of a sociological imagination in the practice of midwifery.”

Barbara Katz Rothman, City University of New York

“The authors set out to ‘stimulate the sociological imagination’ of their readers. The combination of theoretical analysis and application of sociological theory to specific practice situations provides extensive opportunities for this to take place. Readers who are new to the sociology of maternity care will find ample material to excite and engage them. Those who already have dipped into this vast and fascinating field will find new applications, angles and perspectives that can cast a fresh light on why we do what we do in maternity care, and that provide possible routes for positive change in the future.”

Soo Downe, University of Central Lancashire
