Let G be a finite group and k a field of characteristic p > 0. In this paper, we obtain several equivalent conditions to determine whether the principal block B0 of a finite p-solvable group G is p-radical, which means that B0 has the property that e0(kP)G is semisimple as a kG-module, where P is a Sylow p-subgroup of G, kP is the trivial kP-module, (kP)G is the induced module, and e0 is the block idempotent of B0. We also give the complete classification of a finite p-solvable group G which has not more than three simple B0-modules where B0 is p-radical., Xiaohan Hu, Jiwen Zeng., and Obsahuje seznam literatury
Control chart pattern (CCP) recognition is important for monitoring
process environments to achieve appropriate control precisely and quickly and to produce high quality products. CCPs are represented by a large number of inputs. The principal component analysis (PCA) is an effective procedure for reducing a large input vector to a small vector.
This paper describes an efficient approach to reducing the inputs of the networks for CCP recognition with the use of PCA. The reason for applying PCA to CCP recognition is to provide simplicity for the networks and to speed up the training procedure of them. Multilayered perceptrons (MLP) are used and trained with the resilient-propagation (RP) and the backpropagation (BP) learning algorithms. The results show that PCA provides less cornplex neural network structure for accurate and faster training. This helps to achieve the CCP recognition precisely and accurately and rnight even help us to implement the recognition easily within the VLSI technologies for this application.

We study the semigroups isomorphic to principal ideals of finitely generated commutative monoids. We define the concept of finite presentation for this kind of semigroups. Furthermore, we show how to obtain information on these semigroups from their presentations.
Theatrical activities of Václav Mihule (1758 - after 1808) are documented at his various positions in 19 European cities. Born in Prague Mihule left his home at a young age. His earliest experience was as an actor (1781-89), traveling to distant places such as Warszawa (1781), St. Peterburg (1784-86), Königsberg (1787-88), Mainz and Frankfurt a. M. (1788-89). His first Prague ensemble (1789) was a collaboration with Jean Butteau, the company played at ThunPalace Theatre at the Lesser Town of Prague. Later he directed the ensemble Vlastenské divadlo (Patriotic Theatre) in the Theatre U Hybernů (in summer in Karlovy Vary) and the German company at the Nostitz Theatre. After his abrupt departure from Prague in mid 1793 he became a theatre director in Augsburg (1793-94), in Nürnberg, Ansbach, Erlangen, Ulm and Nördlingen (1794-97), Stuttgart (1797), Wiener Neustadt (1797/98), Olomouc (1800-02), Opava (1802-04), Prešov (1805) a Košice (1804-08). He seems to have ended his career in Košice, where he may have died. In the time from 21. 12. 1796 till 13. 9. 1797 he led on lease the Court Theatre Company of Friedrich Eugen II. of Württemberg in Stuttgart. It was in Stuttgart for the first time, when the Court Theatre was rented to a theatre entrepreneur. The Duke tryed in this way to keep the theatre running in the bad economic situation in the course of the War of the First Coalition (1792-1797). For the director Mihule was the offered contract for 6 years - after experience with various theaters in the cities - an extraordinary occasion to achieve a firmly established place of work with above standard conditions. It is possible to describe and characterize the Stuttgart period of the entrepreneur Mihule on the basis of archive documents and account books (aspect of organization) and periodicals (theatre repertory).
