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 ... 
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) ... 
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 ... 
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 ... 
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 ... 
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 ... 
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 ... 
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 ... 
A heuristic procedure for a singleitem dynamic lot sizing problem
(1988)An O(T) heuristic proceudre for a singleitem dynamic lot sizing problem is introduced in this paper. The algorithm tries to establish the regeneration points of the problem whether either the production or the beginning ... 
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 ... 
A sequential dual simplex algorithm for the linear assignment problem
(1988)We present a sequential dualsimplex algorithm for the linear problem which has the same complexity as the algorithms of Balinski [3,4] and Goldfarb [8]: O(n2) pivots, O(n2 log n + nm) time. Our algorithm works with the ... 
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 ... 
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 ... 
Sequential Decoding for Multiple Access Channels
(1988)The use of sequential decoding in multiple access channels is considered. The Fano metric, which achieves all achievable rates in the oneuser case, fails to do so in the multiuser case. A new metric is introduced and an ... 
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 ... 
Sorption of Cesium and Strontium on Montmorillonite and Kaolinite
(1988)Sorption characteristics of Cs+ and Sr++on montmorillonite and kaolinite type clays and soil fractions from various regions of Turkey were studied using the batch method. 137Cs and 90Sr were used as tracers. Concentrations ... 
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 ... 
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 ... 
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 ...
