The utilization of remotely sensed observations for light use efficiency (LUE) and tower-based gross primary production (GPP) estimates was studied in a USDA cornfield. Nadir hyperspectral reflectance measurements were acquired at canopy level during a collaborative field campaign conducted in four growing seasons. The Photochemical Reflectance Index (PRI) and solar induced chlorophyll fluoresc...

For generations, cyclones and tidal surges have frequently devastated lives and property in coastal and island Bangladesh. This study explores vulnerability to cyclone hazards using first-hand coping recollections from prior to, during and after these events. Qualitative field data suggest that, beyond extreme cyclone forces, localised vulnerability is defined in terms of response processes, in...

Abstract A multiscale coupled model is presented that allows for the detailed analysis of local impact urban heat island mitigation measures. The uses computational fluid dynamics (CFD) simulations with unsteady and moisture transport (HAM) in porous materials order to take into account dynamic storage built environment. realistic case study performed a public square City Zurich during wave con...

Walking, as an important transportation mode, plays a large part in urban transportation systems. This mode is of great importance for planners and decision-makers because of its impact on environmental and health aspects of communities. However, this mode is so complex in nature that makes it difficult to study or model. On the other hand, chaos theory studies complex dynamical nonlinear syste...

We present a new algorithm for concurrent access to array-based priority queue heaps. Deletions proceed top-down as they do in a previous algorithm due to Rao and Kumar 6], but insertions proceed bottom-up, and consecutive insertions use a bit-reversal technique to scatter accesses across the fringe of the tree, to reduce contention. Because insertions do not have to traverse the entire height ...

OBJECTIVE The purpose of the present study was to devise a predictive index to predict residual liver function before hepatic resection, using technetium-99m diethylenetriamine-penta-acetic acid-galactosyl human serum albumin (99mTc-GSA) liver dynamic single photon emission computed tomography (SPECT). METHODS Fifty-seven patients with liver disease underwent liver dynamic SPECT with 99mTc-GS...

OBJECTIVE The purpose of this study was to evaluate the influence of 350-rpm rotational speed on the failure incidence of ProFile nickel-titanium rotary instruments (PRI) when used by an experienced operator in conjunction with different motors. STUDY DESIGN Extracted human mandibular and maxillary first and second molars demonstrating curvatures greater than 25 degrees were used. PRI sizes 4...
