Accurate assessment of the quality of concrete bridge decks and identification of corrosion induced delamination lead to economic management of bridge decks. It has been demonstrated that ground penetrating radar (GPR) can be successfully used for such purposes. The growing demand on GPR has brought into the challenge of developing automatic processes(More)
In this paper, we propose an efficient scheme to fast generate three-qubit Greenberger-Horne-Zeilinger (GHZ) state by constructing shortcuts to adiabatic passage (STAP) based on the "Lewis-Riesenfeld (LR) invariants" in spatially separated cavities connected by optical fibers. Numerical simulations illustrate that the scheme is not only fast, but robust(More)
In a dynamic model of merger negotiation assuming two-sided private information and common knowledge of gains from trade, this paper investigates (1) what determines the delay in timing of M&A initiation, and (2) who initiates the M&A negotiation. The key driving force for the results is that the timing of initiation can reveal information about each firm's(More)
Seismic/ultrasonic methods can be successfully used in condition assessment of bridge decks by evaluating changes in material characteristics and detection of development of defects and zones of deterioration. The impact echo method is of special benefit in evaluation of corrosion induced deck delamination due to its nondestructive nature and ability to(More)

—Medical ultrasound image registration is an essential component in an increasing number of applications, and has therefore been the subject of many studies in the literature. These applications use either generic registration algorithms or pixel-to-pixel comparison based ultrasound-specific methods. Hence, they are not well suited for the case of speckled(More)
Assessment of blood flow velocity in Doppler images is of great importance in clinical studies and research. From the Doppler waveform envelope, numerous indices can be obtained, such as the pulsatility index, resistance index, and systolic/diastolic ratio, as well as acceleration of the blood through valves. The evaluation for the Doppler images is usually(More)
