Tests with commercial classical gravimeters in preparation for tests of quantum prototype

Preliminary tests with commercial spring-mass gravimeters have been carried out on the outdoor test field at Ispra in order to establish a test-bed suitable for testing a cold-atom quantum gravimeter. In 2016, the background on a single device was measured. In 2017, a measurements of the field above a buried 5 ton lead mass were carried out, using two gravimeters mounted vertically one above the other. A clear indication of the gravitational field of the test mass with seen, with good signal-to-noise ratio. It was concluded that the general layout is satisfactory, given that the quantum prototype should have sensitivity similar to or better than the conventional instruments. Practical experience gained is helpful for understanding the requirements for mounting and positioning the quantum instrument.JRC.E.2-Technology Innovation in Securit

Design Research is Alive and Kicking...

This paper explores the current situation of design research with a particular emphasis on how emerging forms of design research are framing andaddressing contemporaryglobal issues. The paper examines how design research canbe a creative and transformative force in helping to shape our lives in more responsible, sustainable, and meaningful ways. Today, theplurality in design research is clearlyevident given the wide range of conceptual, methodological,technological and theoretical approaches adopted. Moreover, various forms of design research now routinely appear in a vast array of disciplines in and around modern design praxis, including business, engineering, computing, and healthcare. This paper reviews a rich selection of the state-of-the-art design research that exemplify the range of approaches, methods, applications, and collaborations prevalent in emerging forms of design research and presents 10 characteristics of ‘good’ design research that will support design researchers in addressing the complex global issues we face

An A to Z of contemporary design

In 2001, Hal Foster wrote his paper “The ABCs of Contemporary Design*” (Foster, 2002a) as a supplement (part glossary, part guide) to his book Design and Crime (and Other Diatribes) (Foster, 2002b). Foster’s ABCs paper paints design as being a near‐perfect circuit of production and consumption. Foster claims that critical reflection is outdated, which means design is a consumption‐based system and as such design’s role is largely to feed capitalism, let it flourish, and meet the demands of the masses. Over a decade on from Foster’s critical analysis of design, however, it appears that design is in the middle of yet another series of crises (Bremner and Rodgers, 2013) ranging from disciplinary challenges where the profession of design appears to be struggling with its identity, to epistemological and conceptual challenges where the zeitgeist of design thinking and the widespread democratization of the discipline would have us believe that “we are all designers”, and where the remit of design is expanding into ever more far flung areas that cover communications, services, interactions and strategies. It seems timely and fitting, therefore, that we need a new examination of the contemporary world of design. This assessment of contemporary design is apposite given that we currently inhabit a world that we have all combined to create that is seriously unprepared to deal with the mounting crises we face. Collectively, we are destroying some of the most important features of society that we claim to hold most dear (i.e. our planet, our society, and our spirit). Our ecological crisis, wherein we continue to deplete and degrade our natural capital on a massive scale, using up the equivalent of 1.5 planets to meet our current consumption has resulted in one third of our agricultural land disappearing over the last 40 years, which will inevitably lead to food supply crises and an anticipated doubling of food prices by 2030 (Emmott, 2013). Our present social crisis sees nearly 2.5 billion people on our planet living in abject poverty (UNHDR, 2007). There have been many successes at lifting people out of poverty, but this figure has not changed much over the past few decades (Therborn, 2012). Furthermore, the world is currently in a spiritual crisis where, according to World Health Organization (WHO) statistics, 3 times as many people die from suicide as die from homicide or in wars. These global dimensions are collectively creating results that nobody wants and may well constitute the most significant failure of our time. Building on Foster’s ABC template, the authors present a new critical insight from A to Z into the current design situation where issues of professionalism in design, the global financial meltdown, and the rapid adoption of digital technologies have all modified the models of design thought and action. We suggest readers see this paper as a development of Foster’s original supplement

Bayesian inference from terrestrial gravimetry measurements of near-surface anomalies using a bespoke reversible-jump Markov chain Monte Carlo algorithm

This work describes a Bayesian algorithm developed to tackle the problem of inference from two-dimensional grids of terrestrial gravity measurements. Near-surface voids such as pipelines and tunnels were the motivating application. The forward models used to approximate the gravity signal due to these potentially complex underground anomalies were sums of simple geometrical shapes: the sphere, finite horizontal cylinder and cuboid. The model parameters of these shapes are related non-linearly to the gravity signal. The reversible-jump Markov chain Monte Carlo algorithm was used, allowing changes to the number of objects comprising the forward model. The natural parsimony of the algorithm was shown to be key for obtaining depth information without the need for arbitrary regularisation. Exploring the Bayesian posterior distribution in this way, spatial, geometrical and anomaly mass information can be obtained as outputs from the inference process, given prior information regarding the soil-anomaly density contrast. This was demonstrated both with synthetic noisy gravity and gravity gradient data and with field gravity data obtained using the Scintrex CG-5 commercial gravimeter. The methodology used to obtain field survey data using the CG-5 over multiple days is described, with discussion of the assignment of measurement uncertainty. A 134 point measurement grid was taken above two spatially separate concrete anomalies, for which volume and density information were known. The data was input into the Bayesian inference algorithm, the forward model parameters were successfully inferred within the total uncertainty

Co-designing with people living with dementia

This paper presents research that illustrates how design thought and action has contributed to the co-design and development of a mass-produced product with people living with dementia. The research, undertaken in collaboration with Alzheimer Scotland, has adopted a range of disruptive design interventions for breaking the cycle of well-formed opinions, strategies, mindsets, and ways-of-doing, that tend to remain unchallenged in the health and social care of people living with dementia. The research has resulted in a number of co-designed interventions that will help change the perception of dementia by showing that people living with dementia can offer much to UK society after diagnosis. It is envisaged that the co-designed activities and interventions will help reconnect people recently diagnosed with dementia to help build their self-esteem, identity and dignity and help keep the person with dementia connected to their community, thus delaying the need for formal support and avoid the need for crisis responses. The paper reports on an initial intervention where the author worked collaboratively with over 130 people diagnosed with dementia across Scotland in the co-design and development of a new tartan. The paper concludes with a number of recommendations for researchers when co-designing with people living with dementia

Design Research for Change:A UK perspective

This paper examines the current landscape of design research in the United Kingdom (UK) with a particular focus on UK research councils’ funded projects that aim to make a positive change to society. In recent years, design research in the UK has grown massively in terms of the number of students studying for a postgraduate degree (Masters and PhD), the number of institutions undertaking research, and both the quantity and quality of design-led inter- and multi-disciplinary collaborative research projects. The ongoing work presented here has involved significant data analysis and visualisation of over 18,000 funded research projects in the UK. The paper highlights the recent “social turn” and the increasingly collaborative nature of design for change research projects in the UK. The paper also describes a number of key characteristics found in and across present day design for change research projects

Leg ulceration as a long-term complication of deep vein thrombosis

AbstractObjectiveTo evaluate the role of deep vein thrombosis as a cause of leg ulcers.Patients and methodsA population-based, case-control study was conducted in Central and North Auckland, New Zealand. Cases comprised 241 people aged 40 to 99 years and on the electoral roll, with current leg ulcers (all types). Cases were identified by means of notification from health professionals and by self-referral. Controls were 224 people in the same age group, without leg ulcers, who were selected from the electoral roll by using a stratified random sampling process.Main outcome measuresThe occurrence of leg ulceration as a consequence of exposure to deep vein thrombosis or being at high risk of deep vein thrombosis (that is, people with a family history of deep vein thrombosis, and/or a history of leg fracture and/or hip, leg, or foot surgery).ResultsAfter adjustment for age, sex, and other potential confounding factors, people who had a diagnosed thromboembolism were at almost three times higher risk of having a leg ulcer (odds ratio, 2.92; 95% confidence interval (CI), 1.47 to 6.08). In addition, people who had been at high risk of a venous thrombosis but were not diagnosed with this condition (eg, people with a history of major leg surgery) were also at increased risk of ulceration (odds ratio, 2.25; 95% CI, 1.49-3.42). Overall, 56% (95% CI, 33% - 71%) of leg ulcers were attributed to being at high risk of deep vein thrombosis.ConclusionsDeep vein thrombosis and factors that place people at high risk of deep vein thrombosis are an important cause of leg ulcers in older people. This finding strengthens the rationale for the routine and long-term use of thromboprophylaxis, particularly in high-risk patients
