Over recent years, significant progress has been made in astrogeodetic research with the development of digital zenith camera systems (DZCSs) at ETH Zurich, Switzerland, and the University of Hanover, Germany. The use of charged coupled device (CCD) sensors for star imaging improved the degree of automation, accuracy and efficiency of this modern astrogeodetic instrumentation. With DZCSs, verti...

The structural behaviour of adjacent buildings during a pounding and the impact which has been subject discussion for many years soil-structure interaction (SSI) ignored in design due to its complexity. However, recent research showed that SSI effects can increase lateral deflections structures founded on soft deposits. also affect inter-storey drifts similar founding soil, causing inelastic su...

Recent experiments show that the adsorption of biomolecules on one surface of a microcantilever generates surface stresses that cause the cantilever to deflect. If a second species binds to the adsorbed molecules, the stresses change, resulting in a different deflection. By choosing adsorbed probe molecules that recognize specific molecules, it may be possible to detect pathogens and biohazards...

The Millennium Tower is a 58-story reinforced concrete building that was constructed in San Francisco, California, between 2005 and 2009. founded on an embedded pile-supported mat with pile tips bearing dense marine deposits overlie overconsolidated clay layer known locally as Old Bay clay. This experienced stress increases from self-weight multiple episodes of dewatering 2006 2018 at the site ...
