Opis:
Let \(C\) be a bounded, closed, convex subset of a uniformly convex and uniformly smooth Banach space \(X\). We investigate the weak convergence of the generalized Krasnosel'skii-Mann and Ishikawa iteration processes to common fixed points of semigroups of nonlinear mappings \(T_t\colon C \to C\). Each of \(T_t\) is assumed to be pointwise Lipschitzian, that is, there exists a family of functions \(\alpha_t\colon C \to [0, \infty)\) such that \(\|T_t(x) - T_t (y)\| \leq\alpha_t (x)\|x -y\|\) for \(x, y \in C\). The paper demonstrates how the weak compactness of \(C\) plays an essential role in proving the weak convergence of these processes to common fixed points.

Opis:
Let \(C\) be a convex compact subset of a uniformly convex Banach space. Let \(\{T_t\}_{t \geq0}\) be a strongly-continuous nonexpansive semigroup on \(C\). Consider the iterative process defined by the sequence of equations $$x_{k+1} =c_k T_{t_{k+1}}(x_{k+1})+(1-c_k)x_k.$$ We prove that, under certain conditions on \(\{c_k\}\) and \(\{t_k\}\), the sequence \(\{x_k\}_{n=1}^\infty\) converges strongly to a common fixed point of the semigroup \(\{T_t\}_{t \geq0}\). There are known results on convergence of such iterative processes for nonexpansive semigroups in Hilbert spaces and Banach spaces with the Opial property, and also weak convergence results in Banach spaces that are simultaneously uniformly convex and uniformly smooth. In this paper, we do not assume the Opial property or uniform smoothness of the norm.

Opis:
To what extent does the spectrum of the Laplacian operator on a domain D with prescribed boundary conditions determine its shape? This paper first retraces the history of this problem, then Kac’s approach in terms of a diffusion process with absorbing boundary conditions. It is shown how the restriction to a polygonal boundary for D in this method, which required taking the limit of an infinite number of sides to obtain a smooth one, can be avoided by using the Duhamel method.

Opis:
We consider ordinary differential equations \(u'(t)+(I-T)u(t)=0\), where an unknown function takes its values in a given modular function space being a generalization of Musielak-Orlicz spaces, and \(T\) is nonlinear mapping which is nonexpansive in the modular sense. We demonstrate that under certain natural assumptions the Cauchy problem related to this equation can be solved. We also show a process for the construction of such a solution. This result is then linked to the recent results of the fixed point theory in modular function spaces.

Opis:
Jednym z najważniejszych zagadnień dotyczących środowiska pracy jest identyfikacja i analiza zagrożeń. Zagrożenia określamy na podstawie pomiaru częstości i ilości różnorodnych czynników występujących w środowisku pracy. Pracodawca wskazuje czynniki szkodliwe po przeprowadzeniu rozpoznania źródeł emisji oraz warunków wykonywania pracy, które mają wpływ na poziom stężeń lub natężeń tych czynników lub na poziom narażenia na oddziaływanie tychże. W elektrowniach cieplnych produkujących energię elektryczną z paliw kopalnych (węgiel) prowadzi się badania i pomiary praktycznie większości czynników z grup czynników fizycznych i chemicznych, na które może być narażony pracownik w środowisku pracy. W artykule przedstawiono identyfikację zagrożeń w elektrowni cieplnej i dokonano ich analizy z uwzględnieniem metod eliminacji tych zagrożeń.
One of the most essential issue regarding work environment is identification and analysis of hazards. Hazards are defined based on measurement of frequency and number of various factors occurring at the work environment. The employer specifies harmful factors after recognizing sources of emission and work conditions, which influence levels of concentrations or intensity of the mentioned factors, or level of exposure to the mentioned factors. Tests and measurements of practically all physical and chemical factors, to which the worker at the work environment may be exposed, are carried out in thermal power plants which generate electric energy of fossil fuels (coal). The article covers identification of hazards at the thermal power plant and their analysis considering methods of their elimination.

Introduction and objective. This study aimed to determine the environmental conditions for the occurrence of carpal tunnel syndrome (CTS) in a non-industrial area, and patient-reported outcomes after surgical release. Materials and method. This observational study utilized convenience sampling to screen 100 consecutive patients for carpal tunnel syndrome at the Orthopedic Clinic, using two questionnaires. Data were collected from the Disability of Arm Shoulder and Hand (DASH) questionnaire, and the PROMIS® (Patient-Reported Outcomes Measurement Information System) Upper Extremity and PROMIS® SF 3a questionnaire (Pain Intensity). The relationship of various repetitive musculoskeletal disorders to CTS was validated by questionnaire scores, PROMIS® T-score, and correlation coefficients. Results. Finally, CTS was confirmed by electromyography in 69 patients (55 females and 14 males; average age: 47.5 years). Aging significantly influenced the occurrence of symptoms associated with pain (neck, thoracic, lower back, shoulder, and CTS (p<0.001)). Those employed for longer more frequently declared performing exercises to prevent overload pain (p<0.001). DASH results significantly correlated with the PROMIS Upper Extremity score (r = -0.64; p<0.05). Conclusions. Geographical and environmental conditions indicate that even though working with a computer is described as an essential risk factor for CTS, the study group showed a predominance of elements that were unrelated to working at a computer. CTS also occurred among people working physically, and even among unemployed individuals. The existence of a statistically significant, strong, negative correlation (r=-0.64; p < 0.05) between the results obtained in the questionnaires DASH and PROMIS Upper Extremity has been demonstrated.

Opis:
Introduction: The increasing burden of undernutrition and overnutrition at both ends of the nutrition spectrum in children are often accompanied by adverse consequences in school performance. Children with poor nutritional status had lower scores on tests of cognitive functioning, lower activity levels, and poorer psychomotor development, whereas severe malnutrition often leads to impaired psychological and intellectual development. Purpose: To investigate the relationship between children’s nutritional status, their socioeconomic background as well as their parents’s beliefs, attitudes and practices in child feeding with their academic achievement in school. Materials and methods: Anthropometric measure-ments and socioeconomic background information were collected from systematically selected school children aged 10 to 12 years old (n=309), while information regarding parental child feeding practices were obtained via a set of self-administered questionnaire. Results: Based on the World Health Organization (WHO) growth charts, 10.7% and 18.1% of the children were thin and overweight or obese, respectively. Results also showed that children’s nutritional status, household socioeconomic background and parental child feeding beliefs and practices were interrelated with the children’s academic achievement. Conclusion: These findings justified the need for relevant health and nutrition interventions in schools, especially the children of bottom billion community living in the rural areas.

Opis:
Arrangements for a competition are not only difficult in terms of logiscs of the event, but also require an assurance of quality. In this paper we analyze limitations which arise from design of the contest for robots equipped with a very poor sensor set. This issue is faintly explored – up to now research work usually has focused on results of a certain task and in addition it assumed almost having a free hand with a choice of components. The discussed ques- tion is significant on the grounds of primary principles: objectivity in grading, equal opportunities among participants and preservation of attractiveness of the tournament at the same time. All of our actions have been evaluated through several years of existence of the PozRobot robotics contest. Over a three-year period we had an opportunity to test our approach on nearly 50 teams and almost 150 contestants from many Polish universities. We analyze various aspects of performing the tournament and we indicate solutions to common problems, e.g. we touch upon dealing with an arena and objects which are placed on it. In particular, we propose a list of features which a well-designed competition should fulfill. To show our experience we describe an instance of a model competition. We outline new directions of further development of the contest, which are connected with a structure of the arena and possible changes in the limited set of the sensors.
