The semileptonic B to K1(1270, 1400) decays in QCD sum rules
(IOP Publishing, 2011)We analyze the semileptonic rare decays of the B meson to K1(1270) and K1(1400) axial vector mesons. The B → K1(1270, 1400)_+_− decays are significant flavor-changing neutral current decays of the B meson. These decays are ... -
Sensorless position control of solenoid actuators for soft landing using super-twisting sliding mode control
(SAGE, 2022-07-24)This article presents an open-loop control methodology to achieve lower seating velocities (i.e. soft-landing) for solenoid-based injector systems which are widely used in automotive as fuel injection valves or gas exchange ... -

Severe plastic deformation as a processing tool for strengthening of additive manufactured alloys
(Elsevier, 2021-08)For the first time, the novel combination of multi-pass equal channel angular extrusion/pressing (ECAE/P) and selective laser melting (SLM) was investigated. Herein, four passes of ECAP via route Bc at 150 °C were applied ... -
Silver patterning using an atomic force microscope tip and laser-induced chemical deposition from liquids
(AIP Publishing, 2012)This article presents a new direct patterning technique in which laser photoreduction of silver from a liquid is controlled by a scanning atomic force microscope tip. Contrary to expectations, the tip suppresses, rather ... -
Simplified transfer function approach for modeling frequency dependency of damping characteristics of rubber bushings
(Sage, 2019-09)Physical systems that consist of parts and vibration isolators such as rubber bushings are usually modeled in multibody simulations, where parts are represented as rigid bodies with their mass and inertia properties and ... -
Simulation and analysis of a TET-walker robot motion
(IEEE, 2014)Tetrahedral walker robots are a group of reconfigurable robots which makes them adaptable for the full spectrum of activities in places that wheeled robots are inapplicable. In this paper, two different gaits for a ... -
Simulation-based design and locomotion control implementation for a lower body exoskeleton
(IEEE, 2022)This paper proposes a simulation-based design and locomotion control methodology for an exoskeleton that is aimed at providing assistance to users with ambulatory difficulties. To increase the power-to-weight ratio while ... -
Simultaneous improvement in strength and ductility of severely deformed niobium alloy
(Elsevier, 2020-11-15)The present study is on the improved monotonic response of a severely deformed niobium-based alloy. Nb-1Zr alloy was processed at room temperature using equal channel angular extrusion and cold rolling. After 16 passes, a ... -
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
(Wiley, 2023-11-01)Thermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals ... -
Sliding mode control of an electromechanical solenoid actuator for soft landing
(IEEE, 2018-10-08)Electromechanical solenoid actuators are widely used in industrial applications that require fast and linear motion. High velocities can be achieved in small stroke lengths; in turn the motion results with high-velocity ... -
A soft+rigid hybrid exoskeleton concept in scissors-pendulum mode: A suit for human state sensing and an exoskeleton for assistance
(IEEE, 2019-06)In this paper, we present a novel concept that can enable the human aware control of exoskeletons through the integration of a soft suit and a robotic exoskeleton. Unlike the state-of-the-art exoskeleton controllers which ... -
Solar radiation exergy and quality performance for Iraq and Turkey
(Inderscience Enterprises Ltd., 2018)The present study is conducted with two primary objectives: First, a new formulation for the maximum efficiency of the solar radiation conversion is developed by considering the radiative energy transfer between two surfaces ... -
A solenoid injector based drop-on-demand system for generating large droplets
(American Institute of Physics Inc., 2023-09-01)This paper proposes a drop-on-demand (DOD) system that can produce single droplets of highly repeatable size in the order of 2 mm. This system utilizes an on-the-shelf solenoid injector used in automotive applications. The ... -
Solid state routes for composite materials production
(Elsevier, 2021)Solid-state methods are frequently used to fabricate metal matrix composites, which usually lead to superior mechanical properties compared to liquid state routes. In this article, different solid-state routes including ... -
Solution of near-field thermal radiation in one-dimensional layered media using dyadic Green's functions and the scattering matrix method
