Predictions of astrometric jitter for sun-like stars. II. dependence on ınclination, metallicity, and active-region nesting
(IOP Publishing, 2021)Ultra-precise astrometry from the Gaia mission is expected to lead to astrometric detections of more than 20,000 exoplanets in our Galaxy. One of the factors that could hamper such detections is the astrometric jitter ... -
Predictions of astrometric jitter for sunlike stars. III. Fast Rotators
(IOP Publishing, 2022)A breakthrough in exoplanet detections is foreseen with the unprecedented astrometric measurement capabilities offered by instrumentation aboard the Gaia space observatory. Besides, astrometric discoveries of exoplanets ... -
Predictive modeling of recycled aggregate concrete beam shear strength using explainable ensemble learning methods
(2023)Construction and demolition waste (CDW) together with the pollution caused by the production of new concrete are increasingly becoming a burden on the environment. An appealing strategy from both an ecological and a ... -
Preparation and characterization of porous hydroxyapatite pellets: effects of calcination and sintering on the porous structure and mechanical properties
(Sage Publications Ltd, 2016)In this study, porous hydroxyapatite structures were produced by using urea particles of 600-850 mu m size. Samples with two different urea composition (25 and 50 wt%) were prepared along with samples without any urea ... -
Pull-out strength of screws in long bones at different insertion angles: finite element analysis and experimental investigations
(De Gruyter, 2024)Different types of plates are available to allow insertion of screws for internal fixation of long bone fractures. The aim of the study was to determine the effect of the insertion of screws at different angles on a long ... -

Recollection center location for end-of-life electric vehicle batteries using fleet size forecast: scenario analysis for Germany
(Elsevier, 2021)The number of electric vehicle batteries is expected to increase. Their integration into circular economy requires their recollection at end-of-life. Decision makers need tools to determine suitable locations of recollection ... -
A review on the mechanical properties of natural fiber-reinforced composites
(Springer Science and Business Media Deutschland GmbH, 2021)Natural fibers have drawn attention from the researchers and engineers in recent years due to their mechanical properties comparable to the conventional synthetic fibers and due to their low cost, eco-friendliness, and ... -
SAR moving object imaging using sparsity imposing priors
(Springer, 2017)Synthetic aperture radar (SAR) returns from a scene with motion can be viewed as data from a stationary scene, but with phase errors due to motion. Based on this perspective, we formulate the problem of SAR imaging of ... -
SAR moving target imaging using group sparsity
(European Signal Processing Conference, EUSIPCO, 2013)SAR imaging of scenes containing moving targets results in defocusing in the reconstructed images if the SAR observation model used in imaging does not take the motion into account. SAR data from a scene with motion can ... -
