Analiza narracyjna jako jedna z metod analizy tekstu biblijnego rozwinęła się pod koniec lat 80. XX w. W artykule autor wskazuje twórców i prekursorów tej metody (G. Genette, S. Chatman, D. Rhoas, D. Michie, A. Culpepper), następnie omawia podstawowe elementy narracji: treść i formę (story, discours) oraz sposoby ich analizy. W aspekcie treściowym analizie podlegają wydarzenia, postacie i okoliczności, w warstwie zaś formalnej analizowane są określone zabiegi narracyjne decydujące o sposobie przekazania danego wydarzenia. Autor zaznacza, że analiza narracyjna nie powinna być stosowana w sposób wyłączny, ale wraz z innymi metodami, przede wszystkim, metodą historyczno-krytyczną.
Fractal analysis is one of the rapidly evolving branches of mathematics and finds its application in different analyses such as pore space description. It constitutes a new approach to the issue of their natural irregularity and roughness. To be properly applied, it should be encompassed by an error estimation. The article presents and verifies uncertainties along with imperfections connected with image analysis and expands on the possible ways of their correction. One of key aspects of such research is finding both appropriate place and the number of photos to take. A coarse- grained sandstone thin section was photographed and then pictures were combined into one, bigger image. Fractal parameters distributions show their change and suggest that the accurately gathered group of photos include both highly and less porous regions. Their amount should be representative and adequate to the sample. The resolution influence on the fractal dimension and lacunarity values was examined. For SEM limestone images obtained using backscattered electrons, magnification in the range of 120x to 2000x was used. Additionally, a single pore was examined. The acquired results point to the fact that the values of fractal dimension are similar to a wide range of magnifications, while lacunarity changes each time. This is connected with changing homogeneity of the image. The article also undertakes a problem of determining fractal parameters spatial distribution based on binarization. The available methods assume that it is carried out after or before the image division into rectangles to create fractal dimension and lacunarity values for interpolation. An individual binarization, although time consuming, provides better results that resemble reality to a closer degree. It is not possible to define a single, correct methodology of error elimination. A set of hints has been presented that can improve results of further image analysis of pore space.
In the last decades Real Options Valuation (ROV) has been gaining a leading role among methods of economic evaluation and risk analysis of projects. This method enables valuation of managerial flexibility which includes postponing investments and reformulating of operating strategies of companies. By doing this, the method delivers higher project values than derived from the classical discount approaches, such as NPV. The value of flexibility may be of lower or greater importance - depending on types, configuration and sequence of occurring real options. Common methods of real options valuation are built on lattice models which approximate continuous stochastic process. One of the most popular techniques used for real options valuation - a marketed asset disclaimer approach (MAD) - is based on the binomial tree. The paper presents valuation of the mineral project with three simultaneous options: option-to-expand, option-to-contract and option-to-abandon.
Podejście agregacyjne to obecnie dominujący sposób prowadzenia analiz w badaniach nad działaniami zbiorowymi i ruchami społecznymi. W obrębie metod agregacyjnych działania analizuje się jako sumę wartości odrębnych elementów (zmiennych). Artykuł zawiera praktyczną ilustrację technik uzupełnienia agregacyjnych metod badawczych metodami relacyjnymi w socjologii ruchów społecznych. Autor opisuje wyniki badania, którego przedmiotem był ruch skrajnej prawicy w Polsce, w latach 1990–2013. Po zaobserwowaniu zmian czasowych w wariancji przemocy stosowanej przez ruch skrajnej prawicy, zaistniała potrzeba zastosowania bardziej precyzyjnego narzędzia, które umożliwiłoby wyjaśnienie, dlaczego w określonym przedziale czasowym skala przemocy istotnie zmalała. Regresja logistyczna okazała się tylko częściowo pomocna w ustaleniu warunków, w których przemoc ze strony skrajnej prawicy słabnie. Dopiero relacyjne ujęcie pozwoliło uchwycić najważniejsze cechy „przestrzeni” (pola), w jakiej funkcjonuje ruch skrajnej prawicy w Polsce.
Planning a construction project, the investor frequently faces the choice of the option of the planned investment. Assessment of options is difficult due to the complex nature of construction projects. Various methods of multicriteria evaluation are successfully applied in the assessment and analysis of options. For those methods to work, a handful of information must be prepared beforehand. Among others, it is necessary to establish the assessment criteria and determine their weight for specific cases. This stage is implemented in cooperation with experts. The results of evaluations, obtained on the basis of the experts' opinions, must be processed and prepared. The paper will discuss one possible option for assessing the experts' opinion.

This paper presents the study of the impact of vibration induced by the movement of the railway rolling stock on the Forum Gdańsk structure. This object is currently under construction and is located over the railway tracks in the vicinity of the Gdańsk Główny and Gdańsk Śródmieście railway stations. The analysis covers the influence of vibrations on the structure itself and on the people within. The in situ measurements on existing parts of the structure allow us to determine environmental excitations used for validation and verification of the derived FEM model. The numerical calculations made the estimates of the vibration amplitudes propagating throughout the whole structure possible.
The influence that general contractors and subcontractors have on the operation of a company is immense. Keeping this in mind, the authors have decided to develop and algorithm based on the analysis of partnering relations between construction companies that would select the best possible construction company for the purposes of cooperation. This algorithm, developed for a given construction company, is meant to support its decision-making system in the field of the selection of another construction company to cooperate with. The author has made references to earlier research, in which she had used the ELECTRE III method, and in which she bad analysed the possibility of applying the BIPOLAR method in order to solve the problem of the selection of a construction company to develop partnering relations with. The author provided an example of the calculations performed for a selection of construction companies.
In order to identify the modal parameters of civil structures it is vital to distinguish the defective data from that of appropriate and accurate data. The defects in data may be due to various reasons like defects in the data collection, malfunctioning of sensors, etc. For this purpose Exploratory Data Analysis (EDA) was engaged toenvisage the distribution of sensor’s data and to detect the malfunctioning with in the sensors. Then outlier analysis was performed to remove those data points which may disrupt the accurate data analysis. Then Data Driven Stochastic Sub-space Identification (DATA-SSI) was engaged to perform the modal parameter identification. In the end to validate the accuracy of the proposed method stabilization diagrams were plotted. Sutong Bridge, one of the largest span cable stayed bridge was used as a case study and the suggested technique was employed. The results obtained after employing the above mentioned techniques are very valuable, accurate and effective.
The following analysis investigates selected properties of the language of the tweets used in the interaction with consumers on English and Polish brand profiles. The analysis examines the structure of tweets, word frequency, as well as the frequency of informal and non-standard language items, language mistakes, the use of emoticons and hashtags. The study contrasts the language used by English and Polish representatives and reveals a number of similarities and differences between the corpora. What the corpora share is a high frequency of conventional politeness acts and language structures reflecting a customer-oriented tone of the interaction. Differences are observed in the frequency and use of informal and non-standard structures, emoticons and hashtags, as well as in the structure and complexity of the tweets. The study indicates a lower formulaicity and a greater individualization of the interaction on the Polish profiles.
How is formed the adjective fettleibig (obese)? It may seem an evident derivate from fett (fat) and Leib
(body); however, the NP fetter Leib is as seldom as the adjective is frequent: this sounds paradoxical.
In this contribution, a new way of explaining the formation of this adjective is explored: fettleibig
appears as a subsistance of a in past times rich -leibig-paradigm. Therefore, in a synchronic view, this
adjective is not explained as a derivate, although it remains mainly transparent.
The paper presents the application of the Analytic Hierarchy Process technique to evaluate and choose the best alternative for acquiring hard coal for energy purposes by a potential Investor operating in the mining and energy sector. Six different sources supposed to provide hard coal were analysed, each of which might ensure a secure and independent supply of the material to the newly built coal-fired power plant. When choosing the best decision alternative, the positive and negative impacts of alternatives were considered through the BOCR analysis: benefits (B), opportunities (O), costs (C) and risks (R) analysis. For this purpose, 4 independent hierarchical models were developed. Different models have the same decision alternatives assessed, but they differ in criteria used to develop the models. In each of the models, in accordance with the AHP rules, were calculated final, global weights for the alternatives being assessed. Showing the best alternative was possible by applying the multiplicative formula (B ź O)/(C ź R), which value was used to rank and choose the best alternative from all assessed ones. The best decision alternative is the alternative where the (B ź O)/(C ź R) ratio is the highest.
Buckling and postbuckling response of thin-walled composite plates investigated experimentally and determinated analytically and numerically is compared. Real dimension specimens of composite plates weakened by cut-out subjected to uniform compression in laboratory buckling tests have been modelled in the finite element method and examined analytically based on P-w2 and P-w3 methods. All results were obtained during the experimental investigations and the numerical FEM analysis of a thin-walled composite plate made of a carbon-epoxy laminate with a symmetrical eight-layer arrangement of [90/-45/45/0]s. The instrument used for this purpose was a numerical ABAQUS® program.
The article raised issues related to the design and execution of low-energy objects in Polish conditions. Based on the designed single-family house, adapted to the requirements of the National Fund for Environmental Protection and Water Management ("NF40" standard), the tools to assist investment decisions by investors were shown. An economic analysis and a multi-criteria analysis were performed using AHP method which had provided an answer to the question whether it is worthwhile to bear higher investment costs in order to adjust to the standards of energy-efficient buildings that fulfil a minimal energy consumption's requirements contained in Polish law. In addition, the variant of object that had optimal characteristics due to the different preferences of investors was indicated. This paper includes analysis and observations on the attempts to unify that part of the building sector, which so far is considered to be personalized, and objects in accordance with the corresponding idea are designed as "custom-made".
A village on the outskirts of a city. An analysis and assessment of the west part of Inowrocław for the purposes of spatial planning, The article presents results of a research concerning the landscape of the west part of Uzdrowisko Inowrocław which is characterized by a rural origin and physiognomy, despite being located in the city. The goal of the paper was to identify the resources of that landscape, determine the pace of its transformation, its value, and indicate the possible directions of development. The research consisted in a landscape diagnosis concerning physiognomy aspects in various dimensions (composition, panoramic, and planning), taking advantage of methods used in landscape architecture and urban design. The execution allowed to formulate guidelines concerning the protection and formation of the researched landscape. The goal was also to determine the usefulness of the used model of research proceedings in practice, including indicating the possibilities of implementing the identified results in spatial planning on a local scale. The work has a case study character which conclusions may be helpful in analyzing similar areas and their landscapes.
The research of development capabilities is a fundamental of strategic issues, which has to be taken into consideration by coal mines. This is particularly difficult in the current environment, which is determined by its crisis situation. In such conditions, it is necessary to take difficult decisions, and serious, strategic challenges into account, which allow for the crisis to be overcome, for the renewal and economic effectiveness of the operation of these coal mines, which have potential to grow, and closing the coal mines, which have not potential to grow. Due to the effects of such decisions, which concern not only coal mines but also the Silesian region, it is essential to prepare information to support them and promote rational choices. This is related to the issue of research for development possibilities. The article presents considerations related to the subject of research for development possibilities of coal mines in a crisis situation. Taking the results of literature study into account, the model of research process was developed, and identified the research issues concerning the following:
- the identification of external factors which determine the possibility of development of the Polish mines and drawing a schedule of their changes in the future,
- the identification of internal factors which determine the possibility of development of the Polish mines,
- developing a way for the assessment of the development potential of the coal mines, to show appropriate strategic options and action programmes for these options,
- determining possible strategic options and corresponding schedules, appropriate for the specific nature of the mines.
The proposition of their solutions, which were obtained in the process of using the specific methods and research tools, allowed the guidelines in terms of research of development capabilities of coal mines to be presented.
The iron ore mine owned by the state concern of Luossavaara – Kiirunavaara AB-LKAB state concern has several mining skip shaft hoists for drawing iron ore. Despite using modern systems to secure the travel of these hoists in line with the Swedish regulations, units intended for the emergency breaking of vessels must be used in the so-called free travel paths in the tower and in the shaft sump. The paper discusses the main requirements that, in accordance with the Swedish regulations as regards the operational use of mining shaft hoists, must be met by devices of this type and a solution was proposed for a structure design of the braking unit for the mining shaft hoist installed in the B-1 shaft in the Kiruna mine. The frictional braking system in the form of moving bumping beams was decided to be used in the said hoist, developed in the Cable Transport Department in the University of Science and Technology in Krakow. The action of moving bumping beams consists in these beams, placed at the beginning of free travel paths, not only braking the rushing hoist vessels but also (with the integrated units for vessel capture) performing the function of grips. They secure the vessels against falling down into the shaft after the finished braking process. The advantage of such a solution is that the structural elements: the guiding shank of the tower, the head of the vessel and the bumping beams, transfer many times lower values of dynamic forces at the time of the strike of the vessel against the moving bumping beams when compared with dynamic forces arising at the time of the hit of the vessel against the fixed bumping beams. In the process of designing moving bumping beams, braking simulation is an important stage conducted with a computer program developed in KTL AGH. This program enables the modelling of load-bearing and balance ropes as flexible elements with elastic and suppressing properties. The results of these simulations, especially in the scope of the achieved braking deceleration of the vessels, the values of braking distances and forces in the load-bearing ropes are crucial in confirming the correctness of the assumed concept of the emergency braking system. The braking units in the form of moving bumping beams have been executed by the Polish company Coal-Bud Sp. z o.o. and are now being integrated in the tower and in the shaft sump of the B-1 shaft of the Kiruna mine in Sweden.
CCS (Carbon Capture and Storage) technology is one of the methods that limit the release of carbon dioxide into the atmosphere. However, the high cost of capturing CO2 in this technology is a major obstacle to the implementation of this solution by power plants. The reduction of costs is expected primarily on the side of the capture and separation of CO2 from flue/ industrial gas. The article presents the financial performance of the most popular amine technology (MEA) against mesoporous material about MCM-41 structure obtained from fly ash, impregnated with polyethyleneimine (PEI), for CCS installations. The study was conducted for an investment comprising three key components that provide a full value chain in CCS validation (capture, transport and storage). The mineralogical studies and determination of the physicochemical properties of mesoporous material produced from waste materials such as fly ash allowed us to identify the best class sorbents of MCM-41, which can be used in CO2 capture technologies. Developing an innovative relationship not only allows 100% of CO2 to be removed but also reduces operating costs (OPEX), primarily including energy by 40% and multiple material costs relative to amine mixtures such as MEA.
Celem artykułu jest pokazanie zmian użycia metafor „czerwony autobus” i „autobus” w polskiej kulturze popularnej na przestrzeni ostatnich kilkudziesięciu lat. Znaczenie badania leży w powiązaniu ich ze sposobem przedstawiania społeczeństwa polskiego oraz zbiorowym doświadczaniem i wytwarzaniem emocji. Autorzy zastosowali koncepcje teoretyczne i narzędzia analizy dyskursu. Jako materiał badawczy wykorzystali zbiór 20 polskich utworów muzycznych z lat 1952–2014, w których metafora „autobus” pełniła ważną rolę, wykorzystując ją jako domenę źródłową dla obrazowania stanu zbiorowości. W rezultacie syntetycznego zestawienia treści metafory i zbadania jej umieszczenia w tekście oraz bardziej szczegółowej analizy kontekstowej wybranych utworów autorzy wykazali tendencję do ukazywania społeczeństwa jako wspólnoty ludzi obcych, ale jednocześnie bliskich ze względu na podzielanie pozycji relatywnego wykluczenia, braku zbiorowego celu i indywidualnego wpływu, a także doświadczanie różnych emocji negatywnych.
