Opis:
Machining accuracy can be considerably affected by deflections of machine tool components and the workpiece. This work presents a new approach for real-time deflection compensation, based on control integrated models. A real-time material removal rate (MRR) simulation determines the depth of cut which is used for process force calculation by Kienzle-Equations. Machine tool and workpiece deflections are then derived from a mechanical model using the calculated process forces. For this purpose, control based signals are used as model inputs. The total deviation is sent to the position controller as a setpoint offset. A dynamometer was applied to validate the simulated process forces. The presented approach was validated for cylindrical turning operations on chucked steel shafts. The experiments were carried out on a high-precision slant bed lathe. The results show, that geometrical errors could be reduced by more than 70% on average.

Opis:
In this study we have analysed haplotypes of microsatellite markers of the CFTR gene: IVS8CA, IVS17BTA, IVS17BCA in 17 CF chromosomes of Polish origin and in 19 chromosomes of German origin bearing CF mutations other than ΔF508. In the Polish population, the G542X mutation is connected with haplotypes 16/17-28/32/38-13; in the German population, a more diverse haplotype association has been detected (23-33-13 and 16-32-13). The 1717-1G->A mutation is associated with the 15/16-7-13 haplotype in the Polish population, like the G551D mutation in Germany. The only analysed case of N1303K of Polish origin is connected with the 23-30-13 haplotype, like in the German population. One N1303K chromosome of an entirely different haplotype (16-29-17) turned out to be of Greek origin. These data suggest an ancient, Palaeolithic or Neolithic origin of these mutations in the territory of current Northern Europe.

Opis:
Health care workers (HCW) worldwide are especially exposed to injury by sharp instruments in the course of their duty. The most often executed procedures with injury risk are: intramuscular or subcutaneous injection (22%), taking blood samples, or during intravenous cannulation (20%), and repeatedly replacing the cap on an already used needle (30%). Even a minor sharp injury with only a small loss of blood carries the risk of transfer of over 20 pathogens: Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), HIV/AIDS virus, malaria, syphilis, tuberculosis, brucellosis, herpes virus and diphtheria. The World Health Organization (WHO) estimates that more than two million health care workers experience the stressful event of a percutaneous injury with a contaminated sharp object each year (25-90% of them, however, remain unreported). These exposures result in about 16,000 infections with HCV, 66,000 with HBV and about 1,000 (200-5000) with HIV, which lead to about 1,100 deaths or significant disability. Exposures to sharp injuries and their consequences are highly preventable through simple interventions, such as HBV vaccination, education and providing containers for sharp instruments. Specific guidelines, similar to the American Occupational Safety and Health Administration (OSHA) regulations that have lowered by up to 88% of needle stabbing incidents, should be introduced by the European Union (EU) and other countries. The results of a review of reports leads to the following conclusions: 1) elaboration and implementation of new State regulations, especially in EU countries and in countries where such regulations do not exist; 2) the training of health care personnel should always be undertaken for new employees, and periodically for those already employed; 3) periodical control by appointed inspectors of knowledge of procedures for the prevention of injuries by sharp instruments among health care workers; 4) introducing and training in the use of equipment, which can prevent the sharp injuries; 5) an advanced monitoring system of sharp injuries sustained by worker should also be introduced. Successful implementation of these prevention measures will result in progress for public health and HCW’s health and safety.

Opis:
The investigation of strong automorphisms of Witt rings is a difficult task because of variety of their structures. Cordes Theorem, known in literature as Harrison-Cordes criterion (cf. [1, Proposition 2.2], [3, Harrison's Criterion]), makes the task of describing all the strong automorphisms of a given (abstract) Witt ring W = (G, R) easier. By this theorem, it suffices to find all such automorphisms ơ of the group G that map the distiguished element -1 of the group G into itself (i.e. ơ(-1) = -1) in which the value sets of 1-fold Pfister forms are preserved in the following sense: ơ(D(1, α)) = D(1, ơ(α)) for all α ∈ G. We use the above criterion and the well-known structure of the group G as a vector space over two-element field F2 for searching all automorphisms of this group. Then we check Harrison-Cordes criterion for found automorpisms and obtain all the automorpisms of a Witt ring W. The task is easy for small rings (with small groups G). For searching of all strong automorpisms of bigger Witt rings we use a computer which automatizes the procedure described above. We present the algorithm for finding strong automorphisms of a Witt rings with finite group G and show how this algorithm can be optimized.

Opis:
The problem of general description of the group of automorphisms of any Witt ring W seems to be very difficult to solve. However, there are many types of Witt rings, which automorphism are described precisely (e.g. [1], [2], [4], [5], [6],[7], [8]). In our paper we characterize automorphisms of abstract Witt rings (cf. [3]) isomorphic to powers of Witt rings of quadratic forms with coefficients in finite fields with characteristic different from 2.

Opis:
The notion of Witt ring is fundamental in bilinear algebra. Automorphisms of Witt rings have been investigated until recent years. In this paper we consider Witt rings which are direct products of finite number of other Witt rings. We shall present a necessary condition in order to group of all strong automorphisms of direct product of Witt rings be a direct product of groups of strong automorphisms of Witt rings which are factors in the direct product. Subsequently, there are considered some examples of Witt rings, where described condition is fulfilled.

Opis:
In the paper strong automorphisms of finitely generated Witt rings are considered. Every finitely generated Witt ring can be expressed in terms of Z / 2Z and basic indecomposable Witt rings using the operations of group ring formation and direct product. Groups of strong automorphisms of basic indecomposables and their direct products and the description of all strong automorphisms of any group Witt ring are known. In this paper the strong automorphisms of direct products of group Witt rings are considered. Presented are two wide classes of Witt rings where the group of strong automorphisms is isomorphic to the direct product of groups of strong automorphisms of Witt rings which are factors in the direct product.

Opis:
Two Witt rings that are not strongly isomorphic (i.e., two Witt rings over two fields that are not Witt equivalent) have different groups of strong automorphisms. Therefore, the description of a group of strong automorphisms is different for almost every Witt ring, which requires the use various tools in proofs. It is natural idea to use computers to generate strong automorphisms of the Witt rings, which is especially effective in the case of the finitely generated Witt rings, where a complete list of strong automorphisms can be created. In this paper we present the algorithm that was used to generate strong automorphisms from the infinite group of strong automorphisms of the Witt ring of rational numbers W(Q).
