Czym jest projekt budowlany? Czy jest to stworzone wyłącznie na podstawie wielu przepisów opracowanie będące podstawą realizacji obiektów budowlanych? W istocie dla inwestorów tak jest, jednak proces sporządzania projektu budowlanego jest, w przekonaniu autorów, skomplikowaną siatką powiązań wielu zależności i relacji między różnymi obszarami wiedzy, umiejętności i uwarunkowań. Zaniechania w którymś z wymienionych obszarów prowadzą często do powstawania elementów ryzyka w realizacji inwestycji. Ryzyko to dotyczyć może wszystkich uczestników procesu budowlanego: inwestora, inspektora nadzoru inwestorskiego, projektanta oraz kierownika budowy lub kierownika robót [1]. Stąd badania zostały skoncentrowane na próbie zebrania i przeanalizowania istotnych danych, a następnie ukazaniu ich wzajemnych relacji i powiązań. Dzięki współczesnej technologii i dziedzinie, jaką jest wizualizacja danych, można w obrazowy sposób ukazać wzajemne powiązanie danych przy jednoczesnym uporządkowaniu pozornego chaosu. W pierwszej części artykułu opisano projekt budowlany jako proces i jego części składowe, bazując na przepisach wyjściowych w zakresie wyłącznie podstawowym. W dalszej części scharakteryzowano metodę wizualizacji danych, jej zalety i możliwości. W końcu na potrzeby artykułu przedstawiono wyniki badań nad możliwościami prezentacji procesu projektowego na wybranych przykładach, stanowiących część szerszego obszaru badawczego. Wnioski z zaprezentowanych przykładów i dotychczasowych badań stanowią podsumowanie artykułu.

What is a construction project? Is it only a development based on many regulations that is the basis for the construction works? In fact, this is the case for Investors, but the process of drawing up a construction project is, in the opinion of the authors, a complex network of connections of many dependencies and correlations between different areas of knowledge, skills and conditions. Omissions in any of these areas often lead to risk areas in the implementation of investments. This risk may affect all participants in the construction process: the investor, the investor supervision supervisor, the designer and the site manager or works manager. Therefore, the research focused on trying to collect and analyze relevant data and then show their interrelationships and connections. Thanks to modern technology and the field of data visualization, it is possible to visualize the interconnection of data while at the same time ordering the apparent chaos. The first part of the article describes the construction design as a process and its components based on the basic rules only. Further, the data visualization method, its advantages and capabilities are characterized. Finally, for the purpose of the article, the results of studies on the possibilities of presenting the design process on selected examples, which are part of a wider research area, are presented. Conclusions from the presented examples and previous studies are a summary of the article.

The visualisation of resources is becoming an increasingly important factor in the operations of crisis management teams. The efficiency of crisis management processes depends on the possibility of data exchange between crisis management teams and people within the range of expected and actual threats. An important part of the information provided to people is the description of the condition of the transport system. The authors of this work carried out comparative analyses of visualisation standards in terms of a selected transport system for six selected countries and organisations. Based on the survey results, they managed to assess the functionality and usability of the visualisation of the Polish transport system. This research was based on a modified model of assessment of software functionality and usability. Methods of determining the functionality and usability of a transport system visualisation can help crisis management teams assess the suitability of IT tools for use in mass notification systems. The literature on this subject lacks a scientific analysis of the Polish method of the visualisation of the transport system. Therefore, this study will clearly fill this research gap.

Processing of digital experimental data has become a key part of virtually every research project. As sensors get both more diverse and cheaper, the amount of information to be handled greatly increases as well. Especially fatigue failure modelling requires by its nature large numbers of samples to be processed, and visualised. The presented paper is based on analysis of load data gathered in flight on an unmanned aircraft. A few versions of an analysis program were developed and considered for the use case. Each implementation included ingesting the data files, creating transfer arrays and the “rain flow counting” algorithm. For the sake of the ease of use and functionality, the version based on Python programming language was selected for presentation. Short development iteration time of this approach allowed gaining new insights by tweaking parameters to better represent actual acquired data. Both the results and the software itself can be easily viewed in a web browser and run with modifications without the need to install any software locally. The developed software is meant as a demonstration of capabilities of open source computation tools dedicated to aerospace and mechanical engineering research, where they remain relatively unpopular.

This paper describes a study on opinion analysis applied to both human to chatbot conversations, but also to human to human conversations using data coming from the banking sector. A polarity classifier SVM model applied to conversations provides insights and visualisations of the satisfaction of users at a given time and its evolution. We conducted a study on the evolution of the opinion on the conversations started with the chatbot and then transferred to a human agent. This work illustrates how opinion analysis techniques can be applied to improve the user experience of the customers but also detect topics that generate frustrations with a chatbot or with human experts.

Many sectors require the use of dedicated ICT systems to collect data from dispersed and oftentimes moving measurement systems. This is associated with the increasingly-common use of unmanned vehicles, mostly flying ones, carrying various measurement systems, such as concentration sensors detecting selected gases. The measurement data can be transmitted wirelessly to a central server. The article presents the architecture of a universal ICT tool that, owing to its flexible application programming interface, can be used for integrating, archiving and visualising data coming from a heterogeneous network of measurement devices in real time.

Analysis of multi-sourced data sets for process improvement purposes requires the selection of relevant techniques enabling data visualisation. There are two main approaches in this scope. The first is based on a raw data and requires from the user determination of properties or patterns while the second one is based on computation of aggregate properties and presentation of the derived data. In the paper we propose to visualize aggregated data in relation to spatial dimension for gaining additional knowledge about process performance. We present an example of performance analysis of machinery used in specific kind of industrial process, namely longwall mining. Our proposals extend range of visualisations that can be used in mining process analysis as well as can be applied in longwall monitoring dashboards and for reporting purposes.

Analiza danych w celu usprawnienia procesu wymaga między innymi wyboru odpowiednich technik wizualizacji danych. Istnieją dwa główne podejścia w tym zakresie. Pierwsze opiera się na wykorzystaniu surowych danych i wymaga od użytkownika określenia właściwości lub wzorców dla wizualizacji. Drugie natomiast opiera się na wartościach zagregowanych i prezentacji przekształconych danych. W artykule, w celu uzyskania dodatkowej wiedzy na temat realizacji procesu wydobywczego w wyrobisku ścianowym, zaproponowano wizualizację zagregowanych danych w odniesieniu do wymiaru przestrzennego realizowanego procesu. Jako przykład przedstawiono wizualizację obciążenia organu kombajnu ścianowego w odniesieniu do położenia w ścianie. Przedstawione propozycje rozszerzają zakres wizualizacji, które mogą być wykorzystane w analizie procesu wydobywczego. Mogą również znaleźć zastosowanie w pulpitach menedżerskich (dyspozytorskich).

Different methodologies are used to assess the potential for using high efficiency cogeneration for cooling and heating. They are mostly adapted to the availability of data and tools for their analytical processing. This paper presents the approach applying location intelligence as a tool that allows using geospatial analysis algorithms and geovisualization of its results. Due to the extremely large amount of data and the dependence of the results on their accuracy and the level of aggregation, the initial methodology of the analytical process implied two steps: wide scale mapping by the "top down'' method, and local mapping by "bottom up'' method. However, in order to overcome the problem of regional disparities of quality and the existence of spatial data, certain adaptations of the initial methodology have been made considering the need for a single analytical approach for the entire area of interest. Randomized control of the obtained results indicate that applied geospatial algorithms satisfy the required level of accuracy and reliability of the final methodology.

Most of underground hydrocarbon storage are located in depleted natural gas reservoirs. Seismic survey is the most economical source of detailed subsurface information. The inversion of seismic section for obtaining pseudoacoustic impedance section gives the possibility to extract detailed subsurface information. The seismic wavelet parameters and noise briefly influence the resolution. Low signal parameters, especially long signal duration time and the presence of noise decrease pseudoimpedance resolution. Drawing out from measurement or modelled seismic data approximation of distribution of acoustic pseuoimpedance leads us to visualisation and images useful to stratum homogeneity identification goal. In this paper, the improvement of geologic section image resolution by use of minimum entropy deconvolution method before inversion is applied. The author proposes context and adaptive transformation of images and edge detection methods as a way to increase the effectiveness of correct interpretation of simulated images. In the paper, the edge detection algorithms using Sobel, Prewitt, Robert, Canny operators as well as Laplacian of Gaussian method are emphasised. Wiener filtering of image transformation improving rock section structure interpretation pseudoimpedance matrix on proper acoustic pseudoimpedance value, corresponding to selected geologic stratum. The goal of the study is to develop applications of image transformation tools to inhomogeneity detection in salt deposits.

We consider the problem of visualisation of high dimensional multivariate time series. A data analyst in creating a two dimensional projection of such a time series might hope to gain some intuition into the structure of the original high dimensional data set. We review a method for visualising time series data using an extension of Echo State Networks (ESNs).The method uses the multidimensional scaling criterion in order to create a visualisation of the time series after its representation in the reservoir of the ESN. We illustrate the method with two dimensional maps of a financial time series. The method is then compared with a mapping which uses a fixed latent space and a novel objective function.

Integrating environmental education with information and communication technologies (ICT) creates a unique opportunity to better convey to the young public the idea of protecting the environment. Great ease with which today's students use modern computer tools and techniques provokes their interest in participation in the activities in which such tools and techniques are widely employed. Environmental education is most frequently pursued through extracurricular activities that involve direct interactions of students with nature. Environmental Information Centre UNEP/GRID-Warsaw has undertaken and carried out a project with the goal to create a multi-functional Internet portal presenting the assets of the Kampinoski National Park. The content of the portal was developed by the Park staff; it also included data and information materials created by appropriately trained students and tourists while visiting the area. The Virtual Kampinoski National Park portal contains three virtual educational trails charted leading through the Park.s areas of particular interest and along which a number of protected nature objects can be seen. Each trail is described in a short text supplemented by multimedia materials such as 360° panoramic pictures, movies, sound, as well as nature-related thematic maps and special data files that, prior to venturing out, can be downloaded to mobile navigation devices such as GPS units or PDA units equipped with GPS modules. While on an Internet virtual hike, the user may visit a number of virtual educational trail stops with information about those particular places, see movies showing spring and summer vegetation as well as pictures shot in four directions (north, south, east and west). On a real hike, tourists equipped with GPS or PDA units and specially designed data entry questionnaires (available on the portal to download and printout) may make field observations regarding such important topics as alien tree species (their presence indicating disturbed ecological balance in a given habitat), tourism infrastructure (availability, condition), tourism pressure evidenced by stray paths created besides marked trails, and, finally, wildlife observations. In all cases, they can take measurements of geographic location of a given observed phenomenon and later transfer such field-collected data into the electronic data questionnaires available on the portal. The data is then processed by a special application and finally visualized on the portal for other users. The map server has been developed based on two software solutions, namely MapServer and Maps- Google. The former is used to display various thematic maps presenting individual components of the Park's environment, while the latter can be used to conduct virtual trips in the Park and is equipped with a number of additional multimedia features. Thus, the three educational trails are visualized on the portal along with thematic layers showing nature-related information such as vegetation or forest habitats - all against the background of the ortophotomap. Attached to each trail stop are their GPSmeasured geographic coordinates as well as illustrative materials such as pictures showing the stop and its immediate vicinity. Additionally, selected trail stops are presented by means of 360° panoramas (both photographic and movie) and archival pictures - all of them can be displayed in a special media presentation window. The Virtual Kampinoski National Park.-portal has already been put to a good use during field educational classes for school teachers and students, entitled .Navigation in the backpack.. During the classes, the participants pursued a number of educational tasks while hiking on the trails in the Kampinoski National Park. Collected data (results of field observations and measurements, their geographic coordinates, photographic documentation) were then uploaded onto the portal, processed and visualized. The students used modern navigation tools and - as an additional fun-task - they were engaged in a navigation-based field game called geocaching which is about finding .treasure boxes.-hidden in places of given coordinates.-.Navigation in the backpack.-project proved a very attractive supplement to the schools.-regular curriculum, the students could learn how to use GPS tools in the field and how to creatively use Internet.
