There has not been a significant decline in fatalities, injuries and illnesses in the construction industry despite rigorous efforts of safety professionals and strong governmental enforcement of safety laws. Inappropriate work planning; insufficient communication between workers and supervisors; and lack of safety training are some of the key contributing factors. The utilization of BIM techno...

Optimal recursive decomposition (or DR-planning) is crucial for analyzing, designing, solving or finding realizations of geometric constraint sytems. While the optimal DR-planning problem is NP-hard even for general 2D bar-joint constraint systems, we describe an O(n) algorithm for a broad class of constraint systems that are isostatic or underconstrained. The algorithm achieves optimality by u...

To investigate the effect of metal implants in proton radiotherapy, dose distributions of different, clinically relevant treatment plans have been measured in an anthropomorphic phantom and compared to treatment planning predictions. The anthropomorphic phantom, which is sliced into four segments in the cranio-caudal direction, is composed of tissue equivalent materials and contains a titanium ...

Three-dimensional echocardiography (3DE) and speckle tracking echocardiography (STE) have recently applied as imaging techniques to accurately evaluate left atrial (LA) size, anatomy and function. 3DE and off-line quantification softwares, have allowed, in comparison to magnetic resonance imaging, the most time-efficient and accurate method of LA volume quantification. STE provides a non-Dopple...

allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...

Herein, the numerical simulation of polymeric membrane formation is investigated when a coupling between phase separation and solvent evaporation occurs. A binary polymer/solvent system considered simulations were performed in 2D geometries, first horizontal plan, then vertical cross-section plan. The was simulated using Cahn-Hilliard equations Flory-Huggins theory used to describe thermodynami...
