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.

 

Serendipitous Impact and the Power of No: lessons from CEMP’s Research Away Day

On Friday February 13, 2015 eighteen researchers across all stages of their careers came together for our CEMP Research Away Day. Hosted at the Old School House By the Sea in Boscombe, the day focused on how we can foster our media & education research culture, from REF strategy to collaboration building, both at BU and beyond.

Kicking us off with REF and Impact, Rebecca Edwards from RKEO spoke about key issues including the new Open Access Guidelines and how we can work to evidence our impact. She summed up 8 key points to takeaway:

1. Know your Open Access
2. Go Gold when possible – use RKEO fund
3. Collaborate with other institutions and international colleagues
4. Identify and developing Impact Case Studies
5. Evidencing your Impact as you go along (testimonials, visitor counts, etc)
6. Promote your research on the BU research website
7. Aim to increase research income
8. Focus on PhD registrations and completions

Sound like a gigantic task for just one person? These goals are not for individuals to accomplish alone. Working in teams and groups is key for doing innovative research, producing outputs and building successful bids. Making connections between our work is a necessary beginning.

Isabella Rega’s Making Connections session got the group talking about where our interests intersect. Using three different coloured post-it notes, we wrote down the issues (green), methods (pink) and stakeholders (yellow) that we work with. Participatory research methods, HE teaching and learning, and Education and Social Change emerged as key overlaps.

Out of these connections some concrete plans emerged, including turning fusion project output into educational resources and a participatory methods workshop day.

From project plans to project afterlife, we shifted to speak about documenting and evidencing impact. We looked at four case studies of research projects including ETAG and Copyrightuser.org, their significance and who they reached. Rebecca Edwards provided advice on how we evidence, measure and track our project’s impact. Sometimes these impacts can be anticipated, but more often there is serendipity and surprise.

Tracking Impact

-Tiers of influence
-Is influencing an organisation enough? How do we understand what this was?
-Testimonials
-Formal letters from key institutions
-If you’ve done research at another institution it doesn’t count at our institution. Impact stays at institution. Reason is because it is usually about groups.
-Entire groups can be rewarded for impact
-Demonstrate the evidence of impact on policy —> Following the story
-Distinct contribution of the University
-Can’t always see the impact from the outset —> serendipity involved, not always
-visitors counts and the result of them

After a tasty, if unidentifiable food-filled lunch from Bosconova, we ran a reflection session on barriers to research bidding and publishing. Designed to get us thinking about the personal and structural constraints on our research, the session helped us room-source practical solutions to common challenges.

Richard Wallis got us back up on our feet with a enthusiastic round of Research Speed Dating. Partnering up with colleagues for short bursts of time, we quickly exchanged project ideas offering feedback and fostering more research connections. Julian McDougall and Richard Berger rounded out the afternoon with a go-around. Everyone shared their upcoming plans and outlined the support they would need to achieve them.

Described by participants as a “fantastic day,” we left feeling the best kind of inspired: more excited and less exhausted about the research plans that lay ahead for CEMP’s growing educational research community.

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.

Seminar Postponed: Dancing with Parkinson’s

Lunchtime Seminar POSTPONED on Thursday 12th February 2015 , 1-1.50pm

Dr Sara Houston, Principal Lecturer in Dance at the University of Roehampton

Against the backdrop of a five-year study into dance for people with Parkinson’s, Dr Houston will examine what it means to ‘live well’ with Parkinson’s through those who participate in a dance class.  She will  examine how participants’ aims to ‘stand tall and step boldly’ are embodied and shaped by their dancing experience.  The seminar  will highlight one woman’s claim that dancing makes her feel beautiful, and, as such, is fundamental to her wellbeing. She will debate the challenge that this claim poses to those who argue that beauty in dance is at best unimportant, at worst disenfranchising. In debating this challenge she will create a link between aesthetics and health through a reformulation of the value of beauty in the context of chronic illness and wellbeing. This link will then allow her to discuss how feeling lovely could become relevant and meaningful within the context of participating in dance.

The seminar will be followed by the BU Humanisation Special Interest Group meeting  from  2 -4.30pm  in EB708, Lansdowne Campus. All are welcome.

Showcasing Research Impact in the Faculty of Health and Social Sciences

Research should make a difference, and as the Faculty’s strapline is ‘helping to make people’s lives better’, it is of relevance to us all. Our forthcoming Seminar series will showcase some of the excellent work of the Faculty to inspire other academics and PhD students.

Further information on this Seminar series can be found by clicking on the link below. The first lunchtime seminar will be taking place on Wednesday 4th March, presented by Zoe Sheppard in R302, Royal London House.

Impact Seminar dates 2015

We look forward to seeing you there.

Dancing with Parkinson’s: Standing Tall, Stepping Boldly and Feeling Lovely

Lunchtime Seminar on Thursday 12th February 2015 , 1-1.50pm in EB708, Lansdowne Campus

Dr Sara Houston, Principal Lecturer in Dance at the University of Roehampton

Against the backdrop of a five-year study into dance for people with Parkinson’s, Dr Houston will examine what it means to ‘live well’ with Parkinson’s through those who participate in a dance class.  She will  examine how participants’ aims to ‘stand tall and step boldly’ are embodied and shaped by their dancing experience.  The seminar  will highlight one woman’s claim that dancing makes her feel beautiful, and, as such, is fundamental to her wellbeing.

In debating this challenge she will create a link between aesthetics and health through a reformulation of the value of beauty in the context of chronic illness and wellbeing. This link will then allow her to discuss how feeling lovely could become relevant and meaningful within the context of participating in dance.

Dr Sara Houston is Principal Lecturer in Dance at the University of Roehampton.  Currently, she leads a longitudinal mixed-methods research study examining the experience of dancing with Parkinson’s commissioned by English National Ballet.  Her work won her the BUPA Foundation Vitality for Life Prize in 2011 and she was a Finalist for the National Public Engagement Awards in 2014.  For the last five years, Sara’s project with people with Parkinson’s has developed her work on the intersection between dance as art, health and wellbeing and on the tensions and collaboration between quantitative and qualitative methodologies and between art and therapy models of engagement.  In 2014, Sara won a National Teaching Fellowship from the Higher Education Academy for excellence in teaching.  She is Chair of the Board of People Dancing: the Foundation for Community Dance.  Her book Dancing With Parkinson’s: Art, Community and Wellbeing is in preparation and will be published by Intellect Books.

The seminar will be followed by the BU Humanisation Special Interest Group meeting  from  2 -4.30pm  in EB708, Lansdowne Campus. All are welcome.

Recent methods papers at BU

In the past six weeks we saw the publication of three methods papers by BU academics.     BU’s Joanne Mayoh and her colleague Anthony J. Onwuegbuzie in the USA published a paper on mixed-methods approaches in phenomenology.1  They argue that phenomenological research methods work extremely well as a component of mixed-methods research approaches. The purpose of this article is twofold, they provide: (1) a philosophical justification for using what they label mixed-methods phenomenological research (MMPR); and (2) examples of MMPR in practice to underline a number of potential models for MMPR that can practically be used in future research.

In the Faculty of Health & Social Sciences Catherine Angell and Jane Hunt with Professor Emerita Jo Alexander offer methodological insights into the ‘draw and write’ research method. 2   Their literature review identified that the method has been used inconsistently and found that there are issues for researchers in relation to interpretation of creative work and analysis of data. As a result of this, an improvement on this method, entitled ‘draw, write and tell’, was developed in an attempt to provide a more child-orientated and consistent approach to data collection, interpretation and analysis. This article identifies the issues relating to ‘draw and write’ and describes the development and application of ‘draw, write and tell’ as a case study, noting its limitations and benefits.

Finally, BU Visiting Faculty Emma Pitchforth and CMMPH’s Edwin van Teijlingen together with Consultant Midwife Helen MacKenzie Bryers published a paper advocating mixed-methods approaches in health research.3  This paper outlines the different paradigms or philosophies underlying quantitative and qualitative methods and some of the on-going debates about mixed-methods. The paper further highlights a number of practical issues, such as: (1) the particular mix and order of quantitative and qualitative methods; (2) the way of integrating methods from different philosophical stance; and (3) how to synthesise mixed-methods findings.   This paper is accompanied by an editorial in  Nepal Journal of Epidemiology. 4

Guest Talk “Machine Learning and Computer Vision for Intelligent Surveillance”, 11am 06Feb TAG32

I would like to invite you to a research presentation by Prof. Bailing Zhang, from Xi’an Jiaotong Liverpool University. We are hosting Prof. Zhang here for a week under the support of BU Fusion Funding. Please feel free to forward this invitation to your colleagues and PhD students if it is of their interests.

 

Title: Machine Learning and Computer Vision for Intelligent Surveillance

Time: 11:00-12:00

Date: Friday, 06 Feb 2015

Room: TAG32 (Talbot Campus)

 

Abstract:

The aim of intelligent video surveillance is to develop a way to provide reliable real-time alarms and situation awareness from existing surveillance networks without the enormous cost of intensive human monitoring. The tasks of video surveillance often include the detection of  the presence of people and vehicle and tracking them, and the subsequent analysis of their activities. Such research projects have broad implications for Homeland Security, law enforcement and many other types of military applications. There are many challenges to analyse a vast number of video streams in real-time to detect a range of events relevant to security needs. Computer vision and machine learning are the two interwove technologies for most of the modeling issues in video surveillance, for example, recognizing human behaviors. In this seminar, Dr. Bailing Zhang will briefly outline the ongoing projects with his group at XJTLU and discuss some relevant issues.

 

Biography:

Bailing Zhang received the Master’s degree in Communication and Electronic System from the South China University of Technology, Guangzhou, China, and Ph.D. degree in Electrical and Computer engineering from the University of Newcastle, NSW, Australia, in 1987 and 1999, respectively. He is currently Associate Professor in the Department of Computer Science and Software Engineering at Xi’an Jiaotong-Liverpool University, Suzhou, China. He had been a Lecturer in the School of Computer Science and Mathematics in the Victoria University, Australia since 2003.

Tourism, a global industry, brings with it a number of public health problems, one of which is the spread of sexually transmitted infections transmitted between travellers and hosts.
Previous studies have largely focused on sex workers and sex tourists. This latest paper ‘Nepalese Trekking Guides: A Quantitative Study of Sexual Health Knowledge And Sexual Behaviour’ published yesterday in the Journal of Manmohan Memorial Institute of Health Sciences assesses sexual behaviour, knowledge and condom use among male trekking guides in Nepal. 

A self-administered questionnaire survey (n=324) was conducted using snowball sampling amongst men working as mountain trekking guides in Nepal. Most respondents (59%) had  initiated sex before the age of 18. Most (84 %) reported sexual relations with a woman other than their partner, 46% reported foreign partners, 43% had Nepalese partners, and 28% had concurrent foreign and Nepalese partners. Most (70 %) reported ever having sex with a foreign woman and two-thirds had had sexual intercourse with foreign women in the previous 12 months. Participants’ age, education status, age of first sex, smoking and drinking habits and English proficiency were significant predictors of having sex with foreign women.About 60% reported condom use during their most recent occasion of extra-martial sex. A similar proportion had used a condom during last sexual intercourse with a foreign woman. The likelihood of condom use was associated with a guide’s age, educational level, ethnicity, age of first sex and work experience. Most trekking guides reported sexual relations with foreign women as well as irregular use of condoms. Although sexual health knowledge about among trekking guides is high, some misconceptions still result in unsafe sex. Hence there is an urgent need to revise the existing training for trekking guides and implement appropriate health promotion programmes.

£1 million available to help UK manufacturing firms develop skills to maximise value of innovation

 

The UK Commission for Employment and Skills (UKCES) has launched a new competition challenging manufacturing firms to maximise the value of innovation.

Manufacturing firms have been invited to bid for a share of £1 million to boost UK innovation. The UK Commission for Employment and Skills (UKCES), launching the ‘Skills for Innovation in Manufacturing’ competition , challenges firms to come up with new ways of developing the skills and business practices needed to maximise the value of innovation to the UK economy.

In recent years, the UK has risen up the Global Innovation Index, moving from 14th in 2010 to second place in 2014. However, a government assessment of the UK’s science and innovation system, undertaken for the Department of Business, Innovation and Skills (BIS) in 2014, identified planning, recruiting, training, retention, progression and performance management as weak parts of the system, with worrying deficiencies in basic skills, STEM skills and management. Businesses’ skills, workplace practices, and management are critical to ensuring the value of innovation is maximised.

Paul McKelvie OBE, a Commissioner at the UK Commission for Employment and Skills (UKCES), which is running the competition, commented:

“It is fantastic that the UK is ranked as a front-runner in terms of innovation, second only globally to Switzerland. However, we need to do more to capitalise on this if we want to reap the economic reward and remain competitive. To do this effectively, we need to explore the ‘human factor’ in innovation. This means understanding how to better manage innovations; both in the way processes work and how any innovation is taken to market. It is the development of these skills that we want businesses to focus on when responding to our invitation.

“This competition is a great opportunity for businesses in the manufacturing sector to come together and come up with ideas and solutions that they want to trial and develop to better maximise the value of innovation. By running this competition, I hope that a range of insights will be drawn from the projects we support to improve future business practice and public policy.”

The UK Futures Programme competition invites employer-led proposals from businesses of all sizes in the manufacturing sector to run initiatives lasting 12 months, that focus specifically on the skills required to manage an innovation process and exploit innovative products or services for commercial value. Proposals must be joint investments with employers investing in cash, in kind or both alongside a maximum government contribution of £150,000 per project.

The competition closes at midday on Wednesday 11 March 2015. For more information or to apply visit the competition page.
