Air fuel ratio control using delay resistant closed loop reference model adaptive control
(Hezarfen Havacılık ve Uzay Teknolojileri Enstitüsü, 2018)The focus of this paper is the air fuel ratio control of spark ignited engines. It is known that for an efficient removal of the pollutants from the exhaust gases, air fuel ratio has to be kept within a narrow band around ... -
Comparison of geometric and drive-induced nonlinearities in doubly clamped, thermoelastic nanoelectromechanical systems
(TÜBİTAK, 2019-06)The performance of resonant sensors based on nanoelectromechanical systems depends critically on the maximum amplitude of oscillation reached in the linear regime. The maximum linear amplitude is determined by nonlinear ... -
Smart composites with tunable stress–strain curves
(Springer, 2019-10)Smart composites with tunable stress–strain curves are explored in a numerical setting. The macroscopic response of the composite is endowed with tunable characteristics through microscopic constituents which respond to ... -
On effective behavior of microstructures embedding general interfaces with damage
(Springer, 2019-05)The interface between constituents of a multiphase material exhibits properties different from those of the bulk and can lead to major alternation of the material response. Interface effects are particularly important for ... -
Isogeometric analysis for numerical plate testing of dry woven fabrics involving frictional contact at meso-scale
(Springer, 2019-01)With a view to application to meso–macro decoupled two-scale draping simulations of dry woven fabrics, the method of isogeometric analysis (IGA) is applied to the numerical plate testing (NPT) for their periodic unit ... -
An extended Langhaar’s solution for two-dimensional entry microchannel flows with high-order slip
(Springer, 2019)The tremendous advances in micro-fabrication technology have brought numerous applications to the field of micro-scale science and engineering in recent decades. Microchannels are inseparable part of microfluidic technology ... -
Modelling and analysis of tool deflections in tailored micro end mills
(Inderscience Enterprises, 2019)The deflection of micro end mills has a detrimental effect on surface quality of the machined micro components and adversely affects the achievable dimensional and geometrical tolerances. In this paper, the analysis and ... -
A displacement-based approach to geometric instabilities of a film on a substrate
(Sage Publications, 2019-02)When a thin film adhered to a compliant substrate is growing, it will eventually buckle in order to release the compressive stresses accumulated within the film due to growth. Such geometric instabilities caused by compressive ... -
Systematic study of homogenization and the utility of circular simplified representative volume element
(Sage Publications, 2019-01)Although both computational and analytical homogenization are well-established today, a thorough and systematic study to compare them is missing in the literature. This manuscript aims to provide an exhaustive comparison ... -
Nonlinear nanomechanical mass spectrometry at the single-nanoparticle level
(American Chemical Society, 2019)Nanoelectromechanical systems (NEMS) have emerged as a promising technology for performing the mass spectrometry of large biomolecules and nanoparticles. As nanoscale objects land on NEMS sensors one by one, they induce ... -
Clustering of Janus particles in an optical potential driven by hydrodynamic fluxes
(Royal Society of Chemistry, 2019-06)Self-organisation is driven by the interactions between the individual components of a system mediated by the environment, and is one of the most important strategies used by many biological systems to develop complex and ... -
Molecular and continuum perspectives on intermediate and flow reversal regimes in electroosmotic transport
(American Chemical Society, 2019)Electroosmotic slip flows in the Debye–Hückel regime were previously investigated using molecular dynamics and continuum transport perspectives ( J. Phys. Chem. C 2018, 122, 9699). This continuing work focuses on distinct ... -
Microscopic design and optimization of hydrodynamically lubricated dissipative interfaces
(John Wiley & Sons, Ltd., 2019)A homogenization‐based topology optimization framework is developed, which can endow hydrodynamically lubricated interfaces with a micro‐texture, to achieve optimal macroscopic responses by addressing both dissipative and ... -
One-pot synthesis of organic–inorganic hybrid polyhedral oligomeric silsesquioxane microparticles in a double-zone temperature controlled microfluidic reactor
(Wiley Periodicals, Inc., 2019)Polyhedral oligomeric silsesquioxane (POSS) particles are one of the smallest organosilica nano‐cage structures with high multifunctionality that show both organic and inorganic properties. Until now poly(POSS) structures ... -
Linear and nonlinear stability of a quasigeostrophic mixing layer subject to a uniform background shear
(American Physical Society, 2019)The aim of this work is to shed light by revisiting, from the kernel-wave (KW) perspective, the breakdown of a quasigeostrophic (QG) mixing layer (or vortex strip or filament) in atmosphere under the influence of a background ... -
Peridynamics review
(SAGE Publications Inc., 2019)Peridynamics (PD) is a novel continuum mechanics theory established by Stewart Silling in 2000. The roots of PD can be traced back to the early works of Gabrio Piola according to dell’Isola et al. PD has been attractive ... -
An iterative solution approach to coupled heat and mass transfer in a steadily fed evaporating water droplet
(American Society of Mechanical Engineers, 2019)Inspired by the thermoregulation of mammals via perspiration, cooling strategies utilizing continuously fed evaporating droplets have long been investigated in the field, yet a comprehensive modeling capturing the detailed ... -
The morphological changes upon cryomilling of cellulose and concurrent generation of mechanoradicals
(Elsevier, 2019)Microstructural features such as grain size, grain morphology, and phase fractions have significant influence on process outputs of machining processes. During micro end milling where feed per tooth and depth of cut values ... -
Accommodating new flights into an existing airline flight schedule
(Elsevier, 2019)We present two novel approaches to alter a flight network for introducing new flights while maximizing airline’s profit. A key feature of the first approach is to adjust the aircraft cruise speed to compensate for the ...
