14.00 – 15.15 Didactic Workshop on Research Governance I What is Research? Wyper D, Director of SINAPSE Email: [email protected] Website: www.sinapse.ac.uk In this presentation I shall outline the distinction between research and audit, and between service delivery research and biomedical research. I shall then discuss several issues that influence the quality of research: The benefits of having multi-disciplinary teams The need for multi-centre studies - and pitfalls in multi-centre studies How to attract adequate funding How to disseminate findings How to get research findings implemented. Finally I shall discuss some of the challenges facing NHS employees doing research. New Devices McCarthy J P, Clin Eng Consulting Ltd and Cardiff University School of Engineering email: [email protected] Developing a new device ‘in house’ for use in a research project is subject to different rules and regulations depending on the circumstances. REMEMBER a) Software can be a medical device in its own right even if running on a non-medical computer. b) Accessories (1) to a medical device e.g. a collimator to an LA, are treated as medical devices in their own right. 1. If the required device meets the definition of a ‘medical device’ (2) in the UK Medical Devices Regulations (2007) (based on the EU MDD, 1993 as amended), and if there is a commercially available CE marked device that meets the requirement, don’t reinvent the wheel. 2. If the purpose of the research project is to carry out a clinical investigation of a prototype medical device for which there is envisaged to be commercial potential, an application to MHRA for approval to continue must be made at least 60 days in advance. (3) MHRA will require the usual ethical and research governance assurances. 3. If the purpose of the device is to assist in carrying out the primary purpose of the research, and the device is not envisaged to fall into category 2 above, then the device probably does not fulfil the definition of a medical device and is not subject to the Regulations. 4. If the device does meet the ‘medical device’ definition, but is manufactured and used within the same corporate healthcare institution and there is no intent to commercialize the device, then MHRA guidance is that the Regulations do not apply since there is no ‘placing on the market’. (4) 5. If a CE marked medical device is to be used for a purpose not intended by the manufacturer - off- label use - then the risks and responsibilities fall on the research investigators and these must be made clear in the ethics application. (5) If commercial application is envisaged, then MHRA approval (point 2 above) will be required. 6. If a CE marked medical device is modified, either for routine clinical use or in the course of a research project, the institution authorizing the modification becomes the manufacturer. (5) 6(a) If the purpose of the research project is to investigate the clinical effectiveness of the modified device with a view to commercial application, then point 2 above applies. 6(b) If it is intended only to use the modified device within the same healthcare institution, then point 4 above applies. 7. Documented risk assessments, manufacturing devices using best practice, and meeting the MDD as far as possible, will meet professional obligations (CEng, CSci, HCPC). These steps will also reduce the chance of anything going wrong and give a strong defence in civil law if it does. Difficult situations

  • Free Tools Photosynth
    Free Tools Photosynth Making a Photosynth Creating the best synth starts with the right photos. Here are some key tips: • Take overlapping panoramas from different locations • Have lots of overlap between shots to get good matching • Limit the angles between photos (no more than 25 degrees – at least 15 per full rotation) • Pick scenes or objects with lots of detail and texture • Don’t crop your images before synthing • Rotate your photos to be ‘up’ correctly before synthing Once you have signed in, click the Upload button (top right of page) or click on the Create your Synth icon on the home page. (scroll down). If you do not have the software you will be prompted to download it first. Once it is installed you will see the Create a Synth button. You will see a pop-up window with Start a new synth button. Give your synth a name, tags (descriptive words) and description. Click Add Photos, browse to your files add them. Then click on the Synth button at the bottom of the page. Photosynth will do the rest for you. Making a Panorama Many photosynths consist of photos shot from a single location. Our friends in Microsoft Research have developed a free, world class panoramic image stitcher called Microsoft Image Composite Editor (ICE for short.) ICE takes a set of overlapping photographs of a scene shot from a single camera location, and creates a single high-resolution image. Photosynth now has support for uploading, exploring and viewing ICE panoramas alongside normal synths. Here’s how to create a panorama in ICE and upload it to Photosynth: 1.

  • An Amateur's Guide to Observing and Imaging the Heavens
    An Amateur’s Guide to Observing and Imaging the Heavens An Amateur’s Guide to Observing and Imaging the Heavens is a highly comprehensive guidebook that bridges the gap between ‘beginners and hobbyists’ books and the many specialised and subject-specific texts for more advanced amateur astronomers. Written by an experienced astronomer and educator, the book is a one-stop reference providing extensive information and advice about observing and imaging equipment, with detailed examples showing how best to use them. In addition to providing in-depth knowledge about every type of astronomical telescope and highlighting the strengths and weaknesses of each, the book offers advice on making visual observations of the Sun, Moon, planets, stars and galaxies. All types of modern astronomical imaging are covered, with step-by-step details given on the use of DSLRs and webcams for solar, lunar and planetary imaging and the use of DSLRs and cooled CCD cameras for deep-sky imaging. Ian Morison spent his professional career as a radio astronomer at the Jodrell Bank Observatory. The International Astronomical Union has recognised his work by naming an asteroid in his honour. He is patron of the Macclesfield Astronomical Society, which he also helped found, and a council member and past president of the Society for Popular Astronomy, United Kingdom. In 2007 he was appointed professor of astronomy at Gresham College, the oldest chair of astronomy in the world. He is the author of numerous articles for the astronomical press and of a university astronomy textbook, and writes a monthly online sky guide and audio podcast for the Jodrell Bank Observatory.

  • Immersion in Early Architectural Design in the Age of Computing By
    Immersion in Early Architectural Design in the Age of Computing By Kartikeya Anil Date A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Architecture in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Yehuda E. Kalay, Chair Professor Andrew Shanken Professor Whitney Davis Summer 2018 Abstract Immersion in Early Architectural Design in the Age of Computing by Kartikeya Anil Date Doctor of Philosophy in Architecture University of California, Berkeley Professor Yehuda E. Kalay, Chair This dissertation proposes a concept of immersion as an integral aspect of a general theory of the (early phase) architectural design act in the age of computing. Computing has influenced design in two major ways – as a metaphor shaping contemporary understanding of the design process, and as a machine used in the practice. The history of the relationship between these two modes of influence is traced to locate immersion in a model of the architectural design process. Early design is explored in this study by a comparative study of design across variously technologically mediated sketching environments. This process is considered as an individual process. Collaborative design is set aside. Computing has influenced design in two ways – as a metaphor for the process and as a machine used in the process. These two types of influences could also be understood to define two distinct tracks along which research in computer aided design has been developed. As a machine, computing has been studied in the fields like evaluation simulations in various domains such as acoustics, energy consumption, structural analysis, emergency evacuations, generative models, and representational models.

  • A Statistical Examination of Image Stitching Software Packages for Use with Unmanned Aerial Systems
    A Statistical Examination of Image Stitching Software Packages For Use With Unmanned Aerial Systems John W. Gross and Benjamin W. Heumann Abstract There is growing demand for the collection of ultra-high spatial orthomosaic. This issue is typically addressed using aerial resolution imagery, such as is collected using unmanned aerial photogrammetric techniques. systems (UAS). Traditional methods of aerial photogrammetry One of the more conventional ways to handle the creation are often difficult or time consuming to utilize due to the lack of orthomosaics in aerial photogrammetry is through the of sufficiently accurate ancillary information.

  • OSINT Handbook September 2020
    OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 Aleksandra Bielska Noa Rebecca Kurz, Yves Baumgartner, Vytenis Benetis 2 Foreword I am delighted to share with you the 2020 edition of the OSINT Tools and Resources Handbook. Once again, the Handbook has been revised and updated to reflect the evolution of this discipline, and the many strategic, operational and technical challenges OSINT practitioners have to grapple with. Given the speed of change on the web, some might question the wisdom of pulling together such a resource. What’s wrong with the Top 10 tools, or the Top 100? There are only so many resources one can bookmark after all. Such arguments are not without merit. My fear, however, is that they are also shortsighted. I offer four reasons why. To begin, a shortlist betrays the widening spectrum of OSINT practice. Whereas OSINT was once the preserve of analysts working in national security, it now embraces a growing class of professionals in fields as diverse as journalism, cybersecurity, investment research, crisis management and human rights. A limited toolkit can never satisfy all of these constituencies. Second, a good OSINT practitioner is someone who is comfortable working with different tools, sources and collection strategies. The temptation toward narrow specialisation in OSINT is one that has to be resisted. Why? Because no research task is ever as tidy as the customer’s requirements are likely to suggest. Third, is the inevitable realisation that good tool awareness is equivalent to good source awareness. Indeed, the right tool can determine whether you harvest the right information.
