Computational fluid dynamics of developing avian outflow tract heart valves
(Springer, 2012-10)Hemodynamic forces play an important role in sculpting the embryonic heart and its valves. Alteration of blood flow patterns through the hearts of embryonic animal models lead to malformations that resemble some clinical ... -
Control of the flow past a sphere near a flat wall using passive jet
(Elsevier, 2019)In the present investigation, interactions between the vortices shedding from a single sphere and the boundary layer flow over a flat plate with various gap ratios have been investigated at Re = 5000 using the techniques ... -
DFT and semi-empirical analyses of Cr-3(+) and Fe3+ impurity centers in Cs2NaYF6: Microscopic insight into structural properties
(Elsevier, 2019)A detailed microscopic study of the local geometry was performed for the cation sites in fluoroelpasolite Cs2NaYF6 crystal doped with 3d ions (Cr3+ and Fe3+). Electronic structure of pure, Crdoped and Fe-doped Cs2NaYF6 has ... -
Dynamic stress intensity factors for suddenly loaded structures using enriched finite elements
(Elsevier, 2014-04)In this paper, an efficient finite element formulation for stationary cracks subjected to dynamic impact loading is presented. For impact problems, where wave propagation effects dominate, the onset of rapid crack growth ... -
Femtosecond laser photodisruption of vitelline vessels of avian embryos as a technique to study embryonic vascular remodeling
(SAGE Publications, 2014-12)During cardiogenesis, congenital heart defects (CHDs), generally start as local tissue abnormalities without underlying genetic causes, suggesting abnormal hemodynamics may be an important source. Due to the scarcity of ... -
A generic transformation of advanced materials technologies: towards more integrated multi-materials systems via customized R&D and innovation
(Elsevier, 2015)Starting with the last quarter of the 19th century until recent modern times, rapidly accelerating technological transformations and developments result in better and superior materials and cause improvements in almost ... -
Growth and hemodynamics after early embryonic aortic arch occlusion
(Springer, 2015-08)The majority of severe clinically significant forms of congenital heart disease (CHD) are associated with great artery lesions, including hypoplastic, double, right or interrupted aortic arch morphologies. While fetal and ... -
Hemodynamic patterning of the avian atrioventricular valve
(Wiley, 2011-01)In this study, we develop an innovative approach to rigorously quantify the evolving hemodynamic environment of the atrioventricular (AV) canal of avian embryos. Ultrasound generated velocity profiles were imported into ... -
Influence of TiC, TiN and TiC(N) additions on sintering and mechanical properties of injection moulded titanium based metal matrix composites
(Maney Publishing, 2014-03)Titanium (Ti) matrix composites based on Ti and reinforced with TiN, TiC and TiCN particles, were processed following a powder injection molding route: mixing, preparation of feedstock, moulding, debinding and sintering ... -
Microscopic insight into electronic and structural properties of Cr3+ and Fe3+ impurities in Cs2NaAlF6 via DFT and SPM analyses
(Elsevier, 2019)Allowing high transition metal (TM) ions doping concentrations makes the fluoroelpasolite crystals Cs2NaMF6 (M=Al, Ga) quite interesting in various laser applications. In this study, we explored the influence of the dopant ... -
Optimization of design parameters for Turkish Tirkes (war) bow
(Elsevier, 2014-11)The bow and arrow is a projectile weapon system that predates recorded history and is common to most cultures. The Turkish bow is the most efficient one in its category. Despite of its superiority, Turkish bow is the one ... -
Optimizing crimping operations in cable assembly shops
(WSEAS Press, 2007-12)Long setup times are incurred in the crimping operation of automotive cable assembly shops. Different heads are used to crimp different connectors to the end of operators where the heads on a machine can be changed one ... -
Quantitative three-dimensional imaging of live avian embryonic morphogenesis via micro-computed tomography
(Wiley, 2011-08)Many clinically relevant congenital malformations arise during mid to late embryonic stages. This period is challenging to image quantitatively in live embryos, necessitating the use of multiple specimens with increased ... -
A TSP (1,2) application arising in cable assembly shops
(Palgrave Macmillan, 2005-06)One of the main operations in producing cable systems in the automotive industry is that of cutting/stripping/crimping. The most time-consuming activity in this operation is changing the heads whenever a different connector ... -
VRP12 (vehicle routing problem with distances one and two) with side constraints
(Elsevier, 2013-08)The problem undertaken in this study is inspired from a real life application. Consider a vehicle routing problem where the distances between the customer locations are either one or two. We name this problem as VRP12 in ...
