Distribution of stresses into steel tank shells induced by executive errors
(Latest Advances in Tank Construction Including Problems of Earthquake Resistance'' Moscow State Building University - International Association for Shells and Spatial Structures - IASS - Working group 1 - "Tanks and Silos'', Moscow State Building University. Moskwa, 1999, 1999-10-12)
Reasons for the arising of defects in shells of steel storage tallk uроn its рrоduсtion and erection are considered оп the example of steel tank with volume 50 000 м3 recently built in Poland. Exact саlculations confirm ...
Imperfekcje stalowych zbiornikow walcowych, przyczyny ich powstawania, sposoby ograniczania
(Konferencja: Problemy Eksploatacyjne Baz Magazynowych Produktów Naftowych, Centrum Edukacji ALIAS, 1999-05-11)
Omówiono imperfekcje kształtu spowodowane złą geometrią blach, spawaniem i nierównomiernym osiadaniem fundamentu oraz imperfekcje materiałowe występujące podczas budowy cienkościennych zbiorników stalowych o dużej pojemności ...
The probabilistic approach to the analysis of power distribution systems
(Royal Institute of Technology and IEEE Power Engineering Society, 1995)
Today's electric power distribution systems are complex large-scale systems changing in time and area. Physical phenomena occurring in a distribution system during transmission and distribution of electrical energy are ...
The Effect of Expert Evaluations on the Efficiency of Decision Processes in Power Distribution Systems
(IEEE, 1993)
The paper gives the results of tests carried out for utility operational staff (experts) to estimate the form and parameters of a probability density function of errors (which are committed by experts) in evaluation of ...
Application of statistical and neural approaches to the daily load profiles modelling in power distribution systems
(IEEE, 1999)
Load modelling is, an essential task in economic analysis, operation and planning of distribution systems. Particularly, when a Demand Side Managemenf system is taken into account on a deregulated energy market the knowledge ...

(Wydawnictwo AE w Krakowie, 1990)
Fuzzy model for energy losses calculation in low voltage distribution networks
(ISAP, 1999)
The proper electric energy losses computing is one of the most complex problems in power distribution system analysis, demanding consideration of many factors. The accessibility and credibility of data used in calculations ...
An Evaluation of an Accuracy of the Fuzzy Regression Analysis
(IEEE, 1999)
In distribution system, bus load estimation is complicated because system load is usually monitored at only a few points. As a rule receiving nodes are not equipped with stationary measuring inshwnents so measurements of ...
Możliwości i efekty stosowania tachimetrów elektronicznych do zakładania osnów realizacyjnych dla specjalnych celów
