Inequalities for the vibrating clamped plate problem
(TÜBİTAK, 2001)
We study the eigenvalues of the vibrating clamped plate problem. We have made improvements on the bounds of the ratios of the eigenvalues of the biharmonic operator (clamped plate) using the methods of Payne, Polya, and ...
Synthesis of scalable planar scissor linkages with anti-parallelogram loops
(Springer, 2019)
Scissor linkages are commonly used as mechanisms for scaling objects. They constitute a significant portion of deployable structures. Since 1960s many researchers sought to form novel structures using the scissor units. ...
A critical review of unpowered performance metrics of impedance-type haptic devices
(Springer, 2019)
A kinesthetic haptic device’s performance relies on unpowered, powered and controlled system characteristics. In this paper, a critical review is carried out for the well-known metrics for kinematics, stiffness and dynamic ...
Conductance fluctuations in a-Si:H: Effects of alloying and device structure
(Kluwer Academic Publishers, 2003-10)
We present measurements of conductance noise in undoped a-Si:H and a-SiGe: H thin films in both a transverse and coplanar electrode geometry. For a-Si:H with coplanar electrodes, the noise spectrum is not a pure f-α power ...
Conductance fluctuations in VHF-PECVD grown hydrogenated microcrystalline silicon thin films
(Kluwer Academic Publishers, 2003-10)
Coplanar conductance fluctuations or excess noise of undoped hydrogenated microcrystal-line silicon (μc-Si : H) thin films grown by VHF-PECVD from silane-hydrogen mixtures with silane concentrations from 2% to 6% have been ...
Photoconductivity spectroscopy in hydrogenated microcrystalline silicon thin films
(Springer, 2003-10)
Steady-state photoconductivity and sub-bandgap absorption measurements by the dual-beam photoconductivity (DBF) method were carried out on undoped hydrogenated microcrystalline silicon thin films prepared by VHF-PECVD and ...
Integration of triboluminescent EuD4TEA crystals to transparent polymers: Impact sensor application
(American Chemical Society, 2017-02)
Lanthanide-based organometallic materials are well-known candidate triboluminescent (TL) materials that can show bright emission when a mechanical force is applied. These materials are usually in the form of crystalline ...
Development and validation of a laser-induced breakdown spectroscopic method for ultra-trace determination of Cu, Mn, Cd and Pb metals in aqueous droplets after drying
(Elsevier, 2016-03-01)
The present study reports a fast and accurate methodology for laser-induced breakdown spectroscopic, LIBS, analysis of aqueous samples for environmental monitoring purposes. This methodology has two important attributes: ...
A novel mechanism of dasatinib-induced apoptosis in chronic myeloid leukemia; Ceramide synthase and ceramide clearance genes
(Springer, 2011-11)
Sphingolipids are bioeffector molecules that control various aspects of cell growth, proliferation, apoptosis, and drug resistance. Ceramides, the central molecule of sphingolipid metabolism, are inducer of apoptosis and ...
pH- and electro-responsive characteristics of silk fibroin-hyaluronic acid polyelectrolyte complex membranes
(Elsevier, 2009-10)
pH-responsiveness of recently developed silk fibroin (SF) and hyaluronic acid (HA) polyelectrolyte complex (PEC) membranes and their potential use in electro-responsive drug release systems were investigated. PEC membranes ...
