The most important determinant of whether there is a radon problem is the presence of uranium and radium in the bedrock and overburden. As the permeability of the ground controls the ease with which radon can be transported, any cavity that exists underground has the potential to accumulate elevated levels of radon. Buildings built upon the ground surface have the potential to draw in ground ga...

A high standard education is, nowadays, a clear objective for any modern society. In Portugal, the retrofit of educational buildings has an enormous relevance as demonstrated by the ‘‘Program for Retrofit and Upgrade of High Schools’’. Educational buildings specific characteristics such as high occupancy rates and high amount of time children spend in classrooms make them a special case compare...

In 2007, Kaiser Permanente's (KP) Southern California Region designed and implemented a systematic in-reach program, the Proactive Office Encounter (POE), to address the growing needs of its three million patients for preventive care and management of chronic disease. The program sought staff from both primary and specialty care departments to proactively identify gaps in care and to assist phy...

Urban heat island (UHI) effects can strengthen heat waves and air pollution episodes. In this study, the dampening impact of urban trees on the UHI during an extreme heat wave in the Washington, D.C., and Baltimore, Maryland, metropolitan area is examined by incorporating trees, soil, and grass into the coupled Weather Research and Forecasting model and an urban canopy model (WRF-UCM). By param...

SUMMARY Three Dimensional Building models are excessively used in various applications. Digital Surface Model is the back bone of the 3D building modeling. The automatic DTM generation techniques are not adequate for the built-up areas. The manual 3D digitization of the stereo images is time consuming. Establishing a semi-automatic technique for the 3D building modeling is required. The main go...

It is well known that the most accurate method to detect changes of height is the geodetic precise leveling method. Due to the high demand work and time needed for precise leveling alternative methods are studied to obtain high quality height information. Differential SAR interferometry techniques such as the Persistent Scatterer Interferometry (PSI) method are studied to detect millimeter leve...

When the ground coupled heat pump (GCHP) system is utilized for air conditioning in cooling load dominated buildings, the heat rejected into ground will accumulate around the ground heat exchangers (GHE) and results in system performance degradation. A novel hybrid ground coupled heat pump (HGCHP) system with nocturnal cooling radiator (NCR) works as supplemental heat rejecter is proposed in th...

Reflections, multipath and shadows due to buildings, equipment, and other reflecting objects on the airport surface, make it difficult, if not sometimes impossible for existing Advanced Surface Movement Guidance and Control Systems (A-SMGCS) to reliably cover the whole aerodrome. In these cases another sensor must step in to fill those gaps. Digital video cameras not only can solve these kinds ...

The high vulnerability of the cultural buildings due to seismic actions urged researchers to retrofit them using reversible and compatible techniques. The application of fiber reinforced polymer (FRP) for enhancing the structural behavior of masonry buildings, under seismic actions, has been studied by many researchers. The near-surface mounting (NSM) technique is a relatively new retrofitting ...

Atmospheric turbulence results from the vertical movement of air, together with flow disturbances around surface obstacles which make low- and moderate-level winds extremely irregular. Recent advancements in wind engineering have led to the construction of new facilities for testing residential homes at relatively high Reynolds numbers. However, the generation of a fully developed turbulence in...
