Dynamic congestion control in interconnected computer networks
The authors evaluate a window-based congestion control mechanism in an internetwork environment. They also propose and study two dynamic-window congestion-control algorithms. These algorithms provide further control to the ...
Measurement of sensitivity of different wave modes to subsurface defects
Excitation of acoustic wave modes in a layered solid is investigated when the solid is immersed in a liquid. This is done by computing the reflection coefficient of acoustic plane waves at the liquid-layered-solid interface. ...
Coding method for discrete noiseless channels with input constraints
Summary form only given. Two coding algorithms for discrete noiseless channels with input constraints have been analyzed. The first algorithm, which requires infinite-precision arithmetic and is mainly of theoretical ...
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 ...
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 ...
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 ...
A fast method of calculating diffraction loss between two facing transducers
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 ...
