Bird strike analysis on a typical helicopter windshield with different lay-ups
( Korean Society of Mechanical Engineers , 2014 , Article)In the current paper, bird strike to a typical helicopter windshield is investigated using smoothed particles hydrodynamic (SPH) finite element method. Five types of lay-ups in a windshield (single layer stretch acrylic, ... -
BIRD-VNE: Backtrack-avoidance virtual network embedding in polynomial time
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)The virtual network embedding (VNE) problem is known to be NP-hard, and as a result, several heuristic approaches have been proposed to solve it. These heuristics find sub-optimal solutions in polynomial time, but have ... -
Birth and death of spiral waves in a network of Hindmarsh–Rose neurons with exponential magnetic flux and excitable media
( Elsevier Inc. , 2019 , Article)Spiral waves are spatiotemporal patterns, observed in complex networks of biological oscillators such as heart and brain. In this paper, at first a modified Hindmarsh–Rose model with external electromagnetic radiation and ... -
Bismuth perovskite as a viable alternative to Pb perovskite solar cells: device simulations to delineate critical efficiency dynamics
( Springer New York LLC , 2019 , Article)We have simulated the operation and functionality of a working Bi-based perovskite solar cell device using GPVDM and compared it against a Pb-based device. The results are extremely promising in that they showcase comparable ... -
Bite force changes after surgical correction of mandibular prognathism in subjects with increased vertical dimension: A prospective clinical trial
( Springer , 2021 , Article)Purpose: Occlusal bite force (OBF) is the most important parameter in assessing biting efficiency. The aim of this study was to record OBF changes after surgical correction of high angle maxillary/mandibular (Max/Mand) ... -
