Opis:
In China, the oil and natural gas resources of Bohai Bay are mainly marginal oil fields. It is necessary to build both iceresistant and economical offshore platforms. However, there are many risks during the life cycle of offshore platforms due to the imperfect preliminary design for the Bohai Sea economical ice-resistant structures. As a result, the whole life-cycle design should be considered, including plan, design, construction, management and maintenance design. Based on the demand of existing codes and research of the basic design, structural ice-resistant performance and the reasonable management and maintenance, the life-cycle design theory is discussed. It was concluded that the life-cycle cost-effective optimum design proposed will lead to a minimum risk.

Aim. The aim of the study is a description of the types of training designs, based on various classification criteria and illustrated by examples from the authors’ own practice. Methods. We used theoretical analysis and synthesis of scientific information, as well as modelling the training structure. Results and Conclusions. It was proposed to classify the designs of group training, depending either on the internal logic of the teaching material or on the external organisation of the training. Regarding the logic of presentation certain designs, through the analysis of existing learning approaches, are proposed of training, based on different logic: presentation of information, assimilation of information, B. Bloom's taxonomy, and  competencies formation. Using these designs, it is possible to construct either the whole training or its separate parts (thematic blocks, exercises). The external organisation of the training includes design of the sum of exercises, or of a coherent story.

Opis:
The goal of this paper is to present the author’s thoughts on the possible contribution of quality engineering to sustainable development. It is indicated that in the product life cycle designers have the greatest potential to support this challenge. Arguments have been presented to abandon the commonly accepted paradigm, according to which the overriding goal of the designer is to achieve the highest market value possible measured by the prospected level of demand for the products designed. It is postulated to include the minimization of the risks brought to the natural environment and social relations as a criterion of product design quality. To this goal, it is necessary for designers to pursue both environmentally friendly materials and technologies and design concepts reducing consumers’ pressure on continuously increasing demand. Such an approach will allow for more effective control of consumption, the main cause of the negative effects of economic growth.

Opis:
The article presents the results of the evaluation of the relationship between the way of shaping public space related to ensuring sustainable mobility in the city and the experiences of users influencing the perceptible quality of life. The assessment was carried out for one of the medium-sized cities, which was included in the list of cities threatened with exclusion. The subject of the evaluation was the city multimodal centreorganised around the railway station in Nysa. The aim of the research was to identify a selected, small group of key challenges and recommendations aimed at improving user experience in using a multimodal centre in the city. The article highlights the role of service infrastructure (stops, stations, transfer centres) in the ecosystem of sustainable urban mobility. Each element of this ecosystem (designed in accordance with the idea of universal design) can have a significant impact on the improvement of the perceptible (declared) quality of life in the city, if the applied solutions positively influence the user’s experience (including the sense of comfort and care). The authors focused on the current state of play in order to identify the key areas of intervention needed to improve the user experience in using the multimodal centre in a small and medium sized city. Attention was paid not only to the aspect of infrastructure accessibility, but also to the relations between urban, architectural and engineering solutions in the context of their impact on the assessment of the multimodal centre in terms of its usefulness in three dimensions: functional, rational and perceptible. The summary outlines the process of achieving from the basic solution standard to interoperability. This knowledge will allow better decision making in the planning of user-oriented projects in the city. This may be of particular importance when the conscious objective of the action is to achieve the level of interoperability expected by users of facilities such as, inter alia, a multimodal centre, which is one element of an urban public space with a significant impact on the quality of life of the citizen.

Opis:
The storage-stability of extractable colour in paprika powder is strongly influenced by the processing steps. The purpose of this research work was to decrease the degradation rate of extractable colour of paprika powders to 3-4 ASTA units/month and increase the shelf-life. Fractional factorial experimental design and desirability function-based approach was applied to moderate the adverse effect of the key-importance processing steps on colour agent content. Photochemical-accelerated shelf-life test was used for the empirically-based quality improvement. Post-harvest ripening, drying, sorting (seed content), milling and additives (paprika seed oil, tocopherol extract) were identified as important for the degradation rate of extractable colour. The colour stability was very sensitive to the milling and drying intensity, while proper setup of other processing steps compensated the adverse effect of drying and milling parameters. The supplementation with cold-pressed spice paprika seed oil was demonstrated as a natural way of colour stabilization. At the highest desirability value (0.986) the rate constant of accelerated colour stability test (k) and shelf-life time (θS[100ASTA]) were −0.494 ASTA units/day and 2326 days, respectively. Alternative factor level settings enabled taking into account processing-tradition and efficiency expectation. In these cases, desirability values and the predicted shelf-life were 0.5-0.8 and 712-918 days, respectively. Validation study showed that the real observed rate constant and shelf-life values met the predicted values and their 95% confidence interval.

Opis:
This paper performs the fatigue life analysis of the radial Cylindrical Roller Bearings (CRBs) with consideration of various roller end-flange shapes such as toroidal-toroidal, spherical-toroidal, and spherical-conical. A novel formula for each flange contact deformation in cylindrical roller bearing with different roller end-flange geometry including toroidal geometry is developed. Inner ring misalignment angle and radial deflection results obtained from the present study are verified with numerical and experimental results from the literature. The results approach to that of literature when the flange is changed from toroidal geometry to conical geometry. Using formulas developed in the present study, the effect of various roller end-flange geometries on the bearing life is investigated for different external loadings. It is observed that the bearing life increases when the roller end and flange are changed to toroidal geometry.

Learning Activity Management System (LAMS) has been trialled and used by users from many countries around the globe, but despite the positive attitude towards its potential benefits to pedagogical processes its adoption in practice has been uneven, reflecting how difficult it is to make a new technology based concept an integral part of the education system. In order to investigate and determine the elements that block the adoption of learning design tools in general, the study will review research papers that have been published in recent years on this subject, especially LAMS. The study will discuss patterns of critical aspects related to adoption of learning design tools and derive a framework that can be used in follow-up studies aimed at collecting relevant empirical data from practitioners to identify key progress measures of the adoption process. These measures may be used later to devise strategies that will see increased adoption of online learning design tools such as LAMS in school systems and higher education institutions.

Opis:
As many manufacturing companies are changing their production philosophies from a traditional focus on the manufacturing of the physical product towards a focus on the life cycle of the physical product, it is becoming important to engineer product's life cycle. Even more, many industrial researchers of the last decade see product's life cycle prolonging activities as a business opportunity both in economical and environmental ways. As a result, more focus is now put on the use phase and end-of-life phase, including maintenance and remanufacturing. The analysis of current end-of-life practices identifies significant improvements to product design that reduce the impact of manufactured goods on the environment as whole. Life cycle engineering and product take-back is a routine for many large industries and corporations nowadays, but, it is still a big challenge for a small and medium companies. In context of end-of-life strategies implementation, there is a very little experience for smaller firms, and results are often controversial. This paper will touch material processing equipment end-of-life strategies combination perspectives, real-life implementation of them, benefits and consequences. The case study is made on a basis of a lorry that will be transferred into spoil mixing plant.

Opis:
The essence of urban design is the transformation of the environment in a way that maximizes the quality of human life. The tools to achieve this goal must cope with the complexity of natural and urbanized spaces, and designers use them to anticipate future environmental states. The article presents theoretical considerations, supplemented by the practical implementation of the area in the Swarzędz community, on the relationship between the organization of urban design in the context of multi-level integration (planning, design) and the emergence of a high-quality urban environment. This process requires controlling many parallel threads between which there are dynamic changes in the relationship - the holarchy.
Istotą projektowania urbanistycznego jest transformacja środowiska w sposób zapewniający maksymalizację jakości życia człowieka. Narzędzia służące do osiągania tego celu muszą mierzyć się ze złożonością przestrzeni naturalnej i zurbanizowanej, a projektanci używają je do antycypowania przyszłych stanów środowiska. Artykuł prezentuje teoretyczne rozważania, uzupełnione praktyczną implementacją terenu w Gminie Swarzędz, na temat relacji między organizacją projektowania urbanistycznego w kontekście integracji wielopoziomowej (planowanie, projektowanie), a powstawaniem środowiska zurbanizowanego o wysokiej jakości. Proces ten wymaga kontrolowania wielu paralelnych wątków, między którymi zachodzą dynamiczne zmiany relacji - holarchii.
