Ian Craddock
Ian Craddock graduated with a 1st class BEng in Electronic and Communications Engineering from the University of Bristol in 1992, followed by a PhD in electromagnetics in 1995. Appointed to a lectureship at Bristol his early career comprised modelling microwave antenna structures before taking on leadership of a research project to design a radar device for humanitarian demining, inspired by multistatic radar focussing principles first developed by Professor Ralph Benjamin. The culmination of several years as principal investigator of this project was a working prototype radar which was trialled at outdoor test sites in the UK and Italy. Approached by Professor Alan Preece, then Head of Medical Physics at the Bristol Royal Infirmary, they began to explore whether similar methods could be used to detect tumours in breast tissue. Ian Craddock led the University team, which included Professor Ralph Benjamin, to first model and then build successive prototypes of a radar-based bre ...

Demining
Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves. By contrast, the goal of ''humanitarian demining'' is to remove all of the landmines to a given depth and make the land safe for human use. Specially trained dogs are also used to narrow down the search and verify that an area is cleared. Mechanical devices such as flails and excavators are sometimes used to clear mines. A great variety of methods for detecting landmines have been studied. These include electromagnetic methods, one of which (ground penetrating radar) has been employed in tandem with metal detectors. Acoustic methods can sense the cavity created by mine casings. Sensors have been developed to detect vapor leaking from landmines. Animals such as rats and mongooses can safely move over a minefield and detect mines, and animals can als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Benjamin
Ralph Benjamin (17 November 1922 – 7 May 2019) was a British scientist and electrical engineer. Biography Benjamin was born in Darmstadt, Germany. He attended boarding school in Switzerland from 1937, and was sent to England in 1939 as a refugee. He studied at Ellesmere College and at Imperial College London where he graduated with a 1st class honours in Electronic Engineering. He joined the Royal Naval Scientific Service in 1944, beginning his career at the Admiralty Surface Weapons Establishment (ASWE). Benjamin invented the first trackball called '' roller ball'' in 1946, patented in 1947. Between 1947 and 1957 he developed the first force-wide integrated Command and Control System. This included patenting the use of an interlaced cursor controlled by a tracker ball to link displays to stored digital information, the first ever digital compression of video data, and the creation of the navy's first digital data link and network which is still in use NATO-wide as "Lin ...

Bristol Royal Infirmary
The Bristol Royal Infirmary, also known as the BRI, is a large teaching hospital situated in the centre of Bristol, England. It has links with the nearby University of Bristol and the Faculty of Health and Social Care at the University of the West of England, also in Bristol. The BRI is one of nine hospitals operated by the University Hospitals Bristol and Weston NHS Foundation Trust. It is located on the same site the Bristol Royal Hospital for Children, Bristol Haematology and Oncology Centre, and Bristol Heart Institute (BHI). The Bristol Haematology and Oncology Centre has 49 beds and the Bristol Heart Institute has 107, which are not included in the main hospital's total. History Early history The Bristol Royal Infirmary was founded by public subscription in 1735, making it one of the oldest infirmaries in the United Kingdom. In 1904, Sir George White, who gave Bristol its first electric tramway service and established what was to become the Bristol Aeroplane Company, ...

Breast Cancer
Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin. Risk factors for developing breast cancer include obesity, a lack of physical exercise, alcoholism, hormone replacement therapy during menopause, ionizing radiation, an early age at first menstruation, having children late in life or not at all, older age, having a prior history of breast cancer, and a family history of breast cancer. About 5–10% of cases are the result of a genetic predisposition inherited from a person's parents, including BRCA1 and BRCA2 among others. Breast cancer most commonly develops in cells from the lining of milk ducts and the lobules that supply these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fellow Of The Institute Of Electrical And Electronics Engineers
The Institute of Electrical and Electronics Engineers (IEEE) is a 501(c)(3) professional association for electronic engineering and electrical engineering (and associated disciplines) with its corporate office in New York City and its operations center in Piscataway, New Jersey. The mission of the IEEE is ''advancing technology for the benefit of humanity''. The IEEE was formed from the amalgamation of the American Institute of Electrical Engineers and the Institute of Radio Engineers in 1963. Due to its expansion of scope into so many related fields, it is simply referred to by the letters I-E-E-E (pronounced I-triple-E), except on legal business documents. , it is the world's largest association of technical professionals with more than 423,000 members in over 160 countries around the world. Its objectives are the educational and technical advancement of electrical and electronic engineering, telecommunications, computer engineering and similar disciplines. History Origin ...

Fellow Members Of The IEEE
A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher educational institutions, a fellow can be a member of a highly ranked group of teachers at a particular college or university or a member of the governing body in some universities (such as the Fellows of Harvard College); it can also be a specially selected postgraduate student who has been appointed to a post (called a fellowship) granting a stipend, research facilities and other privileges for a fixed period (usually one year or more) in order to undertake some advanced study or research, often in return for teaching services. In the context of research and development-intensive large companies or corporations, the title "fellow" is sometimes given to a small number of senior scientists and engineers. In the context of medical education in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
