SUMMARY Concrete is the single most widely used building material throughout the UK and the world. A major advantage of properly designed concrete construction is its inherent resistance to the effects of unwanted fires. The detection and location of structural deficiencies in buildings is of vital importance from a health and safety point of view. In some(More)
The University of Nottingham Ningbo China (UNNC) has full access to the Beidou system, QZSS, GLONASS, Galileo and GPS on its campus. Currently UNNC has a number of GNSS receivers that can access the multi-GNSS constellation, these being a ComNav K508 triple frequency GPS/BeiDou/GLONASS system, Unicore UR240-CORS-II and UR240-RTK GPS/BeiDou receivers, Javad(More)
SUMMARY For engineering applications high precision GPS with survey grade receivers allows positioning in real-time to a centimetre level of precision. Many of the error sources affecting the GPS signal have been significantly removed in order to achieve such high precision. However, one error source that is difficult to mitigate is that of the multipath(More)
The behavioral sciences offer theories and methods that are critical to fulfilling the mission of the Centers for Disease Control and Prevention (CDC). Behavioral scientists have been integrated into the epidemiological and biomedical traditions of the agency, thereby broadening the effectiveness of prevention strategies that rely on behavior change.
