Scheduling independent jobs with stochastic processing times and a common due date on parallel and identical machines
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers, 1989)
We propose a heuristic procedure that constructs a schedule for N jobs with stochastic processing times and a common due date on M parallel, identical machines. The criterion is the minimization of the total expected ...
On diagonalization by dynamic output feedback
The purpose of this paper is to draw attention to a casuality degree dominance property in diagonalization problems by dynamic output feedback and constant precompensator. Even in the well-investigated special case of ...
An Upper Bound on the Cutoff Rate of Sequential Decoding
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 long-standing open problem. © 1988 IEEE
Electronic structure of strained Sin / Gen (001) superlattices
(Pergamon Press, 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 ...
Sorption of cesium and strontium on montmorillonite and kaolinite
(De Gruyter Oldenbourg, 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 ...
Digital decoding of in-line holograms
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 ...
Surface metallization of silicon by potassium adsorption on Si(001)-(2×1)
(American Physical Society, 1988)
We present the detailed results of self-consistent and geometry-optimized total-energy, band-structure, and charge-density calculations for a potassium-covered Si(001)-(2×1) surface, and for an unsupported potassium ...
Sequential decoding for multiple access channels
(Institute of Electrical and Electronics Engineers, 1988)
The use of sequential decoding in multiple access channels is considered. The Fano metric, which achieves all achievable rates in the one-user case, fails to do so in the multiuser case. A new metric is introduced and an ...
Sedimentation rates in the central lake constance determined with210Pb and137Cs
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) ...
A transportation type aggregate production model with bounds on inventory and backordering
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 ...
