Current AASHTO specifications provide engineers with a temperature gradient across the depth of the cross section to predict the vertical thermal behavior of bridges. This gradient is based on… (More)
This paper introduces an advanced vision-based system for dynamic real-time displacement measurement of high-rise buildings using a partitioning approach. The partitioning method is based on the… (More)
Abstract The aim of this study is to assess the pullout resistance of superelastic shape memory alloy (SMA) short fibers with different end shapes, which provide different anchoring actions, through… (More)

1MeV Cu2+ ion was implanted into GaN with a dose of 1×1017cm−2 at room temperature. After implantation, the samples were subsequently performed by rapid thermal annealing at 700, 800, and 900°C for… (More)
The origin of a N-related recombination center (E1), at around 0.33 eV below the conduction band minimum (CBM) of chemical beam epitaxy (CBE) grown GaAsN, is discussed based on effect of H… (More)
We reported a case of hemolytic transfusion reaction that was related to multiple RBC antibodies such as anti-E, anti-M, anti-Jkb and anti-Lea after serial RBC transfusions. A forty-nine year old… (More)
Abstract This study evaluated the crack-closing performance of NiTi and NiTiNb shape memory alloy (SMA) fibers in cement mortar beams. In addition, the effects of the geometry and number of SMA… (More)
Abstract This study assesses the flexural capacity of cement mortar beams that are randomly reinforced with discrete NiTi and NiTiNb shape-memory alloy (SMA) fibers. To achieve this goal, material… (More)
