Field testing refers to techniques that operate in the field reveal those faults escape in-house testing. are becoming increasingly popular with growing complexity of contemporary software systems. In this article, we present first systematic survey approaches over a body 80 collected studies, and propose their categorization based on environment system which is performed. We discuss four resea...

On 1st April 2015 the Historic Buildings and Monuments Commission for England changed its common name from English Heritage to Historic England. We are now re-branding all our documents. Although this document refers to English Heritage, it is still the Commission's current advice and guidance and will in due course be re-branded as Historic England. Please see our website for up to date contac...

We present the observational results of a survey for strong gravitational lens systems consisting of extended emission-line galaxies lensed by intervening earlytype galaxies, conducted using integral field units (IFUs) of the Magellan IMACS and Gemini GMOS-N spectrographs. These data are highly valuable for corroborating the lensing interpretation of Hubble Space Telescope imaging data. We show...

Our MAMBO 1.2 mm blank field imaging survey of ∼ 0.75 sqd has uncovered four unusually bright sources, with flux densities between 10 and 90 mJy, all located in the Abell 2125 field. The three brightest are flat spectrum radio sources with bright optical and X-ray counterparts. Their mm and radio flux densities are variable on timescales of months. Their X-ray luminosities classify them as quas...

Near Field Communication (NFC) is an emerging short-range wireless communication technology that offers great and varied promise in services such as payment, ticketing, gaming, crowd sourcing, voting, navigation, and many others. NFC technology enables the integration of services from a wide range of applications into one single smartphone. NFC technology has emerged recently, and consequently ...
