Opis:
The paper deals with a generalization of the notion of partition for wider classes of binary relations than equivalences: for quasiorders and tolerance relations. The counterpart of partition for the quasiorders is based on a generalization of the notion of equivalence class while it is shown that such a generalization does not work in case of tolerances. Some results from [5] are proved in a much more simple way. The third kind of “partition” corresponding to tolerances, not occurring in [5], is introduced.

Opis:
We present a framework of L-fuzzy modifiers for L being a complete lattice. They are used to model linguistic hedges that act on linguistic terms represented by L-fuzzy sets. In the modelling process the context is taken into account by means of L-fuzzy relations, endowing the L-fuzzy modifiers with a clear inherent semantics. To our knowledge, these L-fuzzy modifiers are the first ones proposed that are suitable to perform this representation task for a lattice L different from the unit interval. In the latter case they undoubtedly outperform the traditional representations, such as powering and shifting hedges, from the semantical point of view.

Opis:
In the paper, the numerical simulation of Nowacki's double shear test in the framework of recently proposed viscoplasticity theory for anisotropic solids is presented. The numerical analysis comprises the full spatial modelling and is carried out for the DH-36 steel sheet in adiabatic conditions (the analysis of anisotropic bodies can be led only on 3D models). During analyses, strain rates of order 104-107 s-1 are observed and the process time duration up to full damage (loss of continuity in the localisation zone) is around 150-300 žs. The novelty of the research is focused on the formulation that includes the anisotropy of the intrinsic microdamage process. Thus, it makes possible to obtain qualitatively and quantitatively new results compared with the existing models, like tracing the softening directions and better (closer to experiment) prediction of damage paths.
W pracy przedstawiono numeryczne symulacje testu podwojnego ścinania, zaproponowanego przez prof. Nowackiego, w ramach sformułowania teorii lepkoplastyczności dla anizotropowych ciał stałych. Analizy numeryczne obejmują modele trójwymiarowe i są wykonane dla stali DH-36 w warunkach adiabatycznych (analiza ciał anizotropowych może być przeprowadzona wyłącznie na modelach trojwymiarowych). W trakcie analiz obserwuje się prędkości deformacji rzędu 104-107 s-1, a czas trwania procesu do całkowitego zerwania próbki (utraty ciągłości w strefie lokalizacji) jest z przedziału 150-300 žs. Oryginalność badań wynika z faktu uwzględnienia w definicji konstytutywnego modelu anizotropowego wewnętrznego procesu mikrouszkodzeń. W rezultacie, uzyskane wyniki dają jakościowo i ilościowo nowy obraz procesu, w szczegolności umożliwiają śledzenie kierunkow osłabienia oraz dokładniejsze (bliższe rezultatom eksperymentalnym) odwzorowanie ścieżki zniszczenia.

Opis:
This paper presents a proposal of simultaneous consideration of load and wear associated with it , of tribological systems of ship main engines (intended for ship propulsion) . Based on results of investigations it was assumed that both the load Q (i.e. a cause of wear ) and the wear Z (i.e. an effect of load occurrence) considered in a given time t (0 ≤ t ≤ tn) are random variables Qt and Zt ,respectively. There was characterized operational principle of ship main engines in definite external conditions (WZ) as well as consequences of excessive load of engines. Three hypotheses highlighting relations existing between load and wear of the above mentioned systems, have been proposed. The first of them deals with explanation of stochastic relation between load and wear, the second highlights why it is possible to assume that the load Qt and the wear Zt are positively correlated , and the third – why it is possible to assume that coefficient of correlation between Qt and Zt may be taken close to one.

Opis:
We have analytically examined surface-gravity waves which propagate in space- and time-dependent random velocity fields. Using a perturbative method, we have derived a dispersion relation which is solved for the case of wave-noise whose spectrum E(k,omega) ~ E(k)delta(omega-crk), where delta is Dirac's delta-function and cr is the random phase speed. We have found that for a dispersionless noise resonance occurs when cr is equal to the group velocity cg of the surface-gravity wave. In this resonance the real part of the wave frequency is finite, but its imaginary part exhibits the characteristic 1/x singularity. The wave-noise interacts with a packet of the surface-gravity waves in such a way that the waves are attenuated for cr < cg and are amplified for cr > cg. As the real part is positive for high values of k, the surface-gravity waves are accelerated by the wave-noise.

Opis:
Applying fuzzy relational cognitive maps in dynamic modelling work of the systems involves restrictions deriving from the assumed model parameters. The selection of these parameters depends mostly on abilities of calculating equipment used for the simulation and on the modelling purposes. In most cases it is necessary to balance between increasing the mapping accuracy (which is connected with the calculation time lengthening) and shortening the calculation time (which, in consequence, worsens the accuracy). Additionally, aiming at the accuracy maximization not always can really improve it, but is always connected with the growing of the computational load. In this chapter the analysis of the intelligent cognitive maps work accuracy in the realization dynamic models is elaborated. As a result of the numerical analysis there was shown the existence of certain optimal parameters of analyzed signals fuzzyfication and connected with them sampling parameters in fuzzy arithmetical operations performed during the modelling processes.

Opis:
The aim of this paper is to identify and explore nature of superior-subordinate relationship and the different uses of empowerment in organizations where employees and managers are of different nationalities. The hypothesis formulated in the study was that a correct relationship fosters empowerment, but this is conditioned by whether or not the work environment is an international one. The research was conducted using the CAWI technique on a non-randomly selected sample of 277 respondents, and confirms a positive correlation between empowerment and the quality of relationships, and also between empowerment and the type of relationship. Moreover, the perception of relationships is modified when an international working environment is considered. In all models, the formal relationship proves to be an irrelevant factor in the use of empowerment. As far as the origin of the superior is concerned, when the superior is a foreigner, the quality, and not the type of the relationship, is the crucial factor. However, an informal relationship becomes important when there are no foreigners. This may cause certain threats in a situation where the company expands internationally.

Opis:
Introduction and objective. The quality of a doctor-patient relationship plays a vital role in all fields of medicine. In the case of psychiatry, this role is special as it provides the foundation for the whole therapeutic process. The aim of this study was to investigate the patient’s perspective on psychiatric visits: patient’s attitudes towards the psychiatrist, patient’s view of the patient-psychiatrist relationship, and the patient’s needs and expectations from this relationship. Materials and method. 615 psychiatric outpatients responded to the anonymous questionnaires connected with their attitudes towards the psychiatrist, evaluation of the doctor, and expectations from psychiatric care. The study was conducted in 10 out of 30 public centres for psychiatric care in north-eastern Poland. Results. Generally, the patients liked and positively evaluated their psychiatrists. Patient’s liking for the doctor was connected with the feeling that the doctor also liked the patient, as well as with perceiving the doctor as competent and willing to meet the patient. The longer the treatment with a particular psychiatrist and the rarer need to consult the doctor, the more positive attitude and evaluation of the doctor patients had. According to the patients, the most significant expectations were associated with both conversation with the doctor and receiving emotional support. Conclusions. The key phase for forming the patient-psychiatrist relationship was the first stage of cooperation in which patients created their attitudes towards the doctor without modifying them at further stages. Thus, further studies on learning and developing the ability to establish the relationship with the patient, inspiring the patient’s trust and making psychiatric appointments comfortable from the first meeting, will be highly valuable.
