DIGITAL DECODING OF INLINE HOLOGRAMS.
(1987)Digitally sampled inline 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 ... 
Scanningtunneling microscopy at small tiptosurface distances
(1987)The scanningtunneling microscopy (STM) of graphite at small tiptosurface distances is investigated using the selfconsistentfield pseudopotential method. We have calculated potential, charge density in the region between ... 
Moleculardynamics study of selfinterstitials in silicon
(1987)Results of a moleculardynamics computer simulation are presented for atomic relaxations and relaxation energies for selfinterstitials in a silicon crystal. The StillingerWeber model potential containing two and threebody ... 
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, ... 
An Input/Output Control System for the Dynamic Job Shop
(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
(BirkhäuserVerlag, 1987)Sediment cores from central Lake Constance were dated with210Pb and137Cs. A sedimentation rate of (0.11±0.02) g·cm2·y1 was determined with the210Pb method.137Cs measurements revealed sedimentation rates of (0.11±0.01) ... 
Modelling and control of a wind energy conversion system
(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 ... 
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 ... 
Longrange order and segregation in semiconductor superlattices
(1987)Results of selfconsistent energyminimization calculations provide strong evidence that the ordered phases in epitaxially grown Ga1xAlxAs and strained Si1xGex alloys are metastable, in the sense that segregation into ... 
Continuous processing of images through user sketched functional blocks
(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
(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
(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 ... 

Critical relaxation of the twodimensional threestate Potts model with conserved dynamics
(1988)The dynamical critical exponent z is obtained using the finitesize scaling method for the twodimensional threestate Potts model with conserved dynamics. It is observed that there is a change in the dynamical behaviour ... 
Effect of tip profile on atomicforce microscope images: A model study
(1988)Adopting the empirical silicon interatomic potential of Stillinger and Weber, we investigate the effect of the tip profile on the atomicforce microscope images for a prototype system, Si(001)(2×1), and conclude that the ... 
An Upper Bound on the Cutoff Rate of Sequential Decoding
(1988)An upper bound is given on the cutoff rate of discrete memoryless channels. This upper bound, which coincides with a known lower bound, determines the cutoff rate, and settles a longstanding open problem. © 1988 IEEE 
Efficiency calibration and summation effects in gammaray spectrometry
(Kluwer Academic Publishers, 1988)Precise, absolute γray efficiences (∈γ) and total efficiences (∈T), have been measured at various distances from the detector, using a set of standards. The observed linear variation of ∈γ and ∈T as well as ∈γ/∈T with Eγ ... 
A simple animation package
(1988)This paper discusses a simple animation package that animates sketches drawn by the user through a simple set of operations. The purpose of the animation package is to demonstrate various computer graphics principles to ... 
Electronic structure of strained Sin/Gen(001) superlattices
(1988)Using the empirical tight binding method we have investigated the electronic properties of the Sin/Gen(001) strained superlattices as a function of the superlattice periodicity and the band misfit. For n ≥ 4 we have found ... 
Surface metallization of silicon by potassium adsorption on Si(001)(2×1)
(1988)We present the detailed results of selfconsistent and geometryoptimized totalenergy, bandstructure, and chargedensity calculations for a potassiumcovered Si(001)(2×1) surface, and for an unsupported potassium ...
