Analytical solution for continuous-time Kalman tracking filters with colored measurement noise in frequency domain
(Ieee-Inst Electrical Electronics Engineers Inc, 1994)New expressions are given for analytical solutions to the steady-state Kalman gains of the two-state exponentially correlated velocity (ECV) and the three-state exponentially correlated acceleration (ECA) tracking filters ... -
Viscosity molecular weight determination of polyadenylic acid
(1995)In this study viscosity measurements of polyadenylic acid (PolyA) in aqueous solution were carried out under different conditions. In the absence of any additives, the polymer degraded during flow through the capillary of ... -
Study of small basin hydrology in Anatolia using environmental isotope analysis
(Taylor & Francis Ltd, 1995)The hydrological behaviour of a representative basin in Central Anatolia, Turkey, was studied by isotopic evaluation of water elements. Samples taken from precipitation, groundwater, subsurface water from the unsaturated ... -
Analysis of orthotropic plate structures by the direct-dynamic stiffness method
(Pergamon-Elsevier Science Ltd, 1995)… -
Interpreting the nonideal reverse bias C-V characteristics and importance of the dependence of Schottky barrier height on applied voltage
(Elsevier Science Bv, 1995)This work presents an attempt related to the charging behaviour of interface states to the nonideal forward bias current-voltage (I-V) and the reverse bias capacitance-voltage (C-V) characteristics of A1-nSi Schottky barrier ... -
Covalent immobilization of α-amylase onto pHEMA microspheres: preparation and application to fixed bed reactor
(Elsevier Sci Ltd, 1995)Microspheres of poly(2-hydroxyethyl methacrylate) with and without cross-linker were prepared by suspension polymerization. As the amount of cross-linker increased, the equilibrium water content, enzyme loading, immobilization ... -
Diffusion and selective transport of alkali cations in a polysulfone ion exchange membrane
(Gauthier-Villars, 1995)he diffusion of alkali metals through a charged polysulfonated ICE-450 ion exchange membrane has been measured as a function of pH and conservation of the external solution at 25 degrees C. The permeability and diffusion ... -
Radiation effect on polyadenylic acid in aqueous solution
(Pergamon-Elsevier Science Ltd, 1995)In this study, dilute solution properties of polyadenylic acid (polyA), G values for single strand break formation G(ssb), Arrhenius parameters (25-45 degrees C), the kinetics of strand break in the absence and presence ... -
Herbicide penetration through isolated periderm and cuticular membranes
(1996)The penetration of three herbicides through isolated potato periderm (PM) and pear fruit cuticular membranes (PFCM) as their commercial formulations was examined in two separate experimental methods involving infinite and ... -
Numerical and experimental stress analysis of a polymeric composite hip joint prosthesis
(John Wiley & Sons Inc, 1996)A comparative stress analysis of a polymeric composite hip joint replacement was performed. A prototype short carbon-fiber reinforced PEEK (CF/PEEK) prosthesis was manufactured by injection molding. Finite element (FE) ... -
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ... -
Motion estimation using common spatial frequencies in synthetic aperture imaging
(I E E E, 1996)Correlation processing using fully common spatial frequencies of overlapping subapertures is explored for motion estimation between consecutive excitations in multi-element synthetic aperure imaging. Signals derived from ... -
Beam space processing for low-cost scanners
(I E E E, 1996)A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ... -
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ... -
Natural frequencies of cross-ply laminated singly curved panels
