Opis:
Based on the data collected over a two year time period, which included temperature, wind speed and gas consumption during the day, the effects of weather factors on gas consumption in the city have been established with the use of multiple regression. The impact of a particular month, day (dummy variable) or holiday of a year on the gas consumption has also been determined. The models of linear regression and artificial neural networks have been constructed for determining the gas consumption. An attempt has been made to find the best regression models and compare them to the neural network models with the use of mean absolute percentage error (MAPE).

Opis:
The article presents aspects of family socializing in terms of evolving models of family life. The changes involve interrelations within the family, consequently its mutual understanding is far from what it used to be. It is the result of, inter alia, the growing number of divorce and separation, the number of single parents raising children, matrimonial decision postponement, restraining from procreation or deciding not to have children, the increase of one person households or informal relationships rising popularity.

Opis:
Finite Element Method (FEM) called Finite Element Analysis is a tool for computer-aided engineering and analysis. It is used to solve problems related to changes in the geometry of the structure as a result of external factors. FEM is used to model engineering processes where real objects are converted to discrete models. Finite Element Method uses a method of obtaining approximate solutions by approximation of partial differential equations. The process of testing and mathematical computation model is described by the equations function of the position and time for the nodes. The development of individual models and their groups and definitions of boundary conditions are carried out using computer programs for FEM.

Opis:
A number of definitions and interpretations of the risk concept exist. Many of these are probability-based. In this paper we present and discuss a structure for characterising the definitions, which is founded on a clear distinction between (a) risk as a concept based on events, consequences and uncertainties; (b) risk as a modelled, quantitative concept; and (c) risk descriptions. The discussion leads to a holistic framework for conceptualising and assessing risk, which is based on risk defined by (a), and the probability-based definitions of risk can be viewed as related model parameters and/or risk descriptions. Two ways of detailing the framework are outlined: the relative frequency-based approach and the Bayesian approach. The Framework provides clear guidance on how to think when conceptualising and assessing risk in practice. Such guidance is strongly needed for the risk analysis discipline which is young and characterised by many different risk perspectives and approaches.

Opis:
The epistemology of models has to face a conundrum: models are often described as highly idealised, and yet they are considered to be vehicles for scientific explanations. Truth-oriented—veritist—conceptions of explanation seem thereby undermined by this contradiction. In this article, I will show how this apparent paradox can be avoided by appealing to the notion of fiction. If fictionalism is often thought to lead to various flavours of instrumentalism, thereby weakening the veritist hopes, the fiction view of models offers a framework much richer than it seems at first sight. To do so, I will call upon the concepts of modality, counterfactual structure and credible worlds. In the end, veritism of explanation and fiction can indeed go hand in hand, but the scope of explanations we can hope to draw from models must be more precisely delineated.

Opis:
Australian physical education (PE) is experiencing its second national curriculum reform attempt, with schools around the country at various stages of exploration and implementation of the Curriculum for Health and Physical Education (Australian Curriculum and Assessment Authority, 2014). This paper explores some of the challenges in physical education curriculum implementation past and present. The PE teacher is explained as the key architect of curricula at the school level and therefore the challenge of new curriculum implementation is not so much in the ‘rolling out’ of the artefact but in developing the subject expertise of PE teachers to be able to bring to life the curriculum expectation in the situated realities of the everyday pragmatics of the PE teacher. Principally, I argue the PE teacher must see their role as that of educational designer.

The intelligent decision making requires the consideration of current contextual information. The article is devoted to construction of formal models for the presentation and usage of contextual information for decision-making in the field of employment. The paper analyses existing approaches to the definition of the concept of context at the conceptual level. The results of comparison of formal context models taking into consideration the requirements for employment business processes are presented. The ontological approach is selected as a basis for contextual models specification. The paper presents the formal representation of the context models for business operations of the employment sector. The model of contextual graphs for the solution of the problem of employment business operations context refinement was developed.

As human population on Earth has just reached seven billion, food, freshwater and energy supplies are of increasing concern. With fisheries supporting hundreds of millions livelihoods and most of the global capture fisheries production coming from the marine environment, sustainable management of fishing activity based on sound scientific data and reasonable predictions is one of the major issues we face these days. Literature review of the most recent publications on the state of global fisheries was conducted and ten main trends were identified, including expansion of fishing to new ecosystems and species, decline in landings, increase in fishing effort, growth of aquaculture and changes in the abundance and distribution of species. Issues with predicting the future were discussed, as well as usefulness of computer models and possible recovery of the ecosystem.

Opis:
Results from a series of five surveys among five groups of international climate scientists about their evaluation of elements of climate models and of climate change are presented. The first survey was done in 1996, the latest in 2015/16. Thus, our snapshots of the opinions of climate scientists cover 20 years. The results describe a strong increase in agreement concerning issues of manifestation of climate change, i.e., that the warming is real and not influenced by changing measuring and reporting practices, and concerning attribution of this ongoing climate change to ongoing anthropogenic causes. On the other hand, the evaluation of the climate models has changed little in the past 20 years. There are still significant reservations with the models ability to incorporate clouds and to describe rainfall. Obviously the growing conviction of ongoing man-made climate change is based on a variety of explanations, with modelling not being the predominant line of evidence. We suggest that it may be the repeated assessments by the IPCC, based on paleoclimatic evidence and stringent statistical analysis of the instrumental record which have led to the growing consensus of the warming and its causation. We stress that the presented results concern the opinion of climate scientists with a rather broad background. Our results do not assess if the opinions of the surveyed scientists are “valid” or “right”, but they recognize the character of science being a social process.

The aim of the paper is an analysis of work effects of HPGR-based technological circuits in industrial mineral processing operations. High-pressure grinding rolls technology is currently one of the most effective methods of raw materials comminution both from the scope of the crushing products quality as well as the environmental effects associated with a lower environmental nuisance. In the first part of investigations the effective control of the particle size distribution of crushing products through the proper selection of operating pressure in the press. In the next stage the HPGR products were ground in a ball mill. The results showed that the grinding efficiency at higher values of operating pressure is greater, it was also observed a rapid increase in yield of the fine particle fractions, which can be directed to initial flotation operations. In the next stage, a methodological assumptions for optimization of a multi-stage comminution circuit were presented. In order to optimize the work effects of circuit the feed preparation manner for each stage of crushing should be taken into consideration. Another aspects which should not be missed are the crushing and grinding devices operating conditions (the relationship between the feed properties and the construction and operating parameters of the device) and characteristics of obtained products.

Opis:
Diagnostics of many common technical objects (compressor blades, oil pipelines) has been noticed to be realized mostly on the basis of measured diagnostic signals resulting from object operation without sufficient consideration given to usually difficult to measure signals of its environment. Such approach is inconsistent with basic rule of diagnostics that strictly orders research and analysis of technical condition in environment (PN-90/N-04002). Hence many works occurred concerning diagnostics of technical objects (e.g. compressor blades – in motion and in repose), characterized by the fact, that environment signals are taken into consideration without necessity of measuring them [2-7]. A necessity exists to elaborate new object diagnostic methods in repose and in operation including environment but without need (if possible) of using frequently unavailable or difficult to measure environment signals. This problem is solved by diagnostic methods based on diagnostic models allowing, through special operations, for elimination of real environment. Elimination of environment from model is possible as an effect of proper conduct of diagnostic research that in base form should include measurement of environment and diagnostic signals. In models A2 T12T01 and φT12T01 dependence on environment does not occur. Hence each change of model must be interpreted only as change of object technical condition. Such models might be applied for various objects operating in complex environments (eg. oil pipelines, bearings, etc.).

Opis:
The great usefulness of uniaxial visco-elastic models, especially in highway engineering pavement theory, composites and other civil engineering disciplines were the reason for undertaking the trial to find a complete solution for the generalization of Kelvin-Voigt body. Here the elements of higher rank than velocities of strain and stress are considered. Carson’s transformation simultaneously with residuum theorem are used for solutions derivation. The introduced procedure can be also used for more complicated differential or integral forms of constitutive equations, as well as for non homogenous initial conditions. The Burgers’ body is examined. Finally, as an example the vibration of simple beam is shown.
Użyteczność jednowymiarowych modeli lepko-sprężystych, szczególnie w zagadnieniach nawierzchni drogowych, kompozytach i innych dziedzinach inżynierii lądowej stała się przyczyną podjęcia próby znalezienia kompletnego rozwiązania uogólnionego modelu Kelvina-Voigta, przy czym w modelu uwzględniono także przyspieszenia tak naprężeń jak i odkształceń. Do uzyskania rozwiązań wykorzystano transformację Carsona oraz twierdzenie o residuach. Zastosowana procedura może być także użyta w przypadkach bardziej złożonych związków konstytutywnych w formie różniczkowej lub całkowej, jak również przy niejednorodnych warunkach początkowych. Rozpatrzono szczególny przypadek analizowanego uogólnienia tj. model Burgersa. Jako aplikację zamieszczono przykład analizy drgań belki swobodnej.
