In this paper we investigate the use of evolution strategy (ES) for the bin packing problem. We used (1, λ)-ES, where 10 children are generated from one parent by means of a simple genetic operators; the crossover is not applied. The best of the descendants becomes the new parent solution. A widely known ordering representation modified for the purposes of(More)
Anterior pituitary hyperplasia and histologically verified adenomas were induced by diethylstilboestrol (DES) containing implants in a total of 104 female F344 rats. Thirty rats were used as controls. Blood flow in the anterior pituitary (PBF) was measured using the hydrogen clearance method. PBF was progressively reduced to 25% by DES in 13 weeks but the(More)
Group Technology (GT) is philosophy, which aims to decompose a manufacturing system into autonomous subsystems (groups). The objective is to aggregating similar parts into families and dissimilar machines into cells such that inter-cell movement of parts is minimized. From the works by E. Falkenauer it appears that a standard scheme and elements of an(More)
The authors discuss the results of surgical treatment of 45 patients with giant intracranial aneurysms calling attention to more frequent occurrence of subarachnoid haemorrhage as the presenting signs, and to the most effective treatment method that is closing of aneurysm neck with a clip, especially in aneurysms of the internal carotid artery. Ligation of(More)
Amantadine, a well-known antiviral agent, causing an increase in dopamine synthesis, release and the inhibition of re-uptake of noradrenaline and dopamine in central and peripheral catecholaminergic neurons, is successfully used in the treatment of Parkinson's disease. In the present paper, we have studied the effect of various doses of amantadine on in(More)
After a review of the modern views on the problem of the so called Tarlov's cysts the authors present a group of 20 patients with chronic low back pains in whom periradicular cysts were diagnosed demonstrating them by means of Dimer-X radiculography. In the light of an analysis of this material the authors reach the conclusion that there are no specific(More)
