Focusing surface waves using an axicon
(A I P Publishing, 1985-12)Axicons are generators of waves which focus on a line. They are used in various imaging and nondestructive testing applications as bulk wave focusing devices with a very long depth of focus. In this letter, a new type of ... -
Modelling and control of a wind energy conversion system
(Taylor & Francis, 1987)The dynamical model of a novel low power wind energy conversion system consisting of a wind turbine, an induction generator, a PWM a.c. inverter and a d.c. battery group is obtained. A feedback control law is developed to ... -
Digital decoding of in-line holograms
(SPIE, 1987)Digitally sampled in-line holograms may be linearly filtered to reconstruct a representation of the original object distribution, thereby decoding the information contained in the hologram. The decoding process is performed ... -
An Input/Output control system for the dynamic job shop
(Taylor & Francis, 1987)A combined input/output control system is presented for periodically determining the set of jobs to be released (input variables) and the capacities of processing centers (output variables) in the dynamic job shop, so that ... -
Sedimentation rates in the central lake constance determined with210Pb and137Cs
(Birkhäuser-Verlag, 1987)Sediment cores from central Lake Constance were dated with210Pb and137Cs. A sedimentation rate of (0.11±0.02) g·cm-2·y-1 was determined with the210Pb method.137Cs measurements revealed sedimentation rates of (0.11±0.01) ... -
Increasing the sensitivity of the scanning acoustic microscope to anisotropy
(IEEE, 1987)The response of the scanning acoustic microscope to anisotropic materials is theoretically investigated. For this purpose, the reflection coefficient of plane acoustic waves incident on a liquid-anisotropic-solid interface ... -
The influence of money and the rate of interest on the rate of inflation in a financially repressed economy: The case of Turkey
(1987)This study takes as its task the explanation of movements in the rate of inflation. It seeks to discover the dynamic process by which monetary expansion and changes in the rate of interest have their effects upon the level ... -
Metallization of Silicon upon Potassium Adsorption
(1987)We report novel features of potassium deposition on a Si(111)-(2×1) surface as a function of coverage. The binding is ionic even at the saturation coverage without any overlayer metallization. Up to a threshold coverage, ... -
Scanning-tunneling microscopy at small tip-to-surface distances
(1987)The scanning-tunneling microscopy (STM) of graphite at small tip-to-surface distances is investigated using the self-consistent-field pseudopotential method. We have calculated potential, charge density in the region between ... -
Molecular-dynamics study of self-interstitials in silicon
(American Physical Society, 1987)Results of a molecular-dynamics computer simulation are presented for atomic relaxations and relaxation energies for self-interstitials in a silicon crystal. The Stillinger-Weber model potential containing two- and three-body ... -
Long-range order and segregation in semiconductor superlattices
(1987)Results of self-consistent energy-minimization calculations provide strong evidence that the ordered phases in epitaxially grown Ga1-xAlxAs and strained Si1-xGex alloys are metastable, in the sense that segregation into ... -
Generation of focused surface waves with a solid wedge
(IEEE, 1987)Focusing of surface acoustic waves on material surfaces was achieved by axicons in liquid immersion. The system consisted of a plane acoustic wave generator obliquely insonifying a cylindrical mirror placed perpendicularly ... -
Continuous processing of images through user sketched functional blocks
(Wiley-Blackwell, 1988)Our aim is to implement an image processing system with previously defined algorithms through the use of functional blocks connected together to form a diagram that we call a schematic. A functional block means the ... -
A fast method of calculating diffraction loss between two facing transducers
(IEEE, 1988)A fast method of calculating the diffraction loss between two facing circular ultrasonic transducers of unequal size is presented. This problem is directly applicable for minimization of diffraction loss in acoustic lens ... -
A transportation type aggregate production model with bounds on inventory and backordering
(Elsevier, 1988)We consider a certain T period aggregate production planning model, where the two sources of production are regular and overtime. The model allows for time varying production, holding and backordering costs and includes ...
