Multidimensional GIS for satellite imagery analysis
- Krzysztof Drypczewski
- Łukasz Markiewicz
- Andrzej Stepnowski
Multidimensional Geographical Information System allows storing, querying and processing of multidimensional query data. It is able to process satellite imagery and provide tools for its analysis. In the article authors present the developed system that analyzes a time series of SENTINEL - 1 mission satellite imagery acquired over the coast of Poland. The algorithm used finds and detects changes in the shape of the coastline over a long period of time. The system uses a Raster Data Manager array database management system to simplify the process of data querying, trimming, storing and analysing. Authors present how the recent trends in GIS development, like RASDAMAN, can be applied to satellite imagery processing.

- Henryk Krawczyk
- Paweł Lubomski
Despite many efforts, there is still a serious problem in transferring knowledge from research to business. The problem is especially visible in Poland – the cooperation of R2B is ineffective. We are trying to solve this problem using some IT support. The manuscript presents some solutions developed at the Gdańsk University of Technology. In particular, the platform called “MOST Knowledge” is deeply described. Its layer architecture, and some new services which it offers are shown. A new interdisciplinary approach is proposed to communicate and support the cooperation of these different worlds. Summarizing, a short comparison with other available platforms is included and discussed.

- Piotr Szczuko
- Michał Lech
- Piotr Odya
- Agnieszka Kwiatkowska
is evaluated on 9 patients, data analysis methods are described, and experiments of correlating Glasgow Coma Scale with extracted features describing subjects performance in therapeutic exercises exploiting EEG and eyetracker are presented. Performance metrics are proposed, and k-means clusters used to define concepts for mental states related to EEG and eyetracking activity. Finally, it is shown that the strongest correlations are between the number of detected mental states and GCSe score, and between maximal length of mental state and GCSm. Weaker correlations are reported as well. Moreover an approach to classification of real and imaginary motion of limbs is presented and discussed. Classifiers based on SVM, Artificial Neural Networks, and Rough Sets were trained and accuracy reaching 91% for the real, and up to 100% for the imaginary type of motion was observed. ssessments of communication skills and therapy is possible with the system, already employed in long-term care facility.

An experimental multimodal system, designed for polysensory diagnosis and stimulation of persons with impaired communication skills or even non-communicative subjects is presented. The user interface includes an eye tracking device and the EEG monitoring of the subject. Furthermore, the system consists of a device for objective hearing testing and an autostereoscopic projection system designed to stimulate subjects through their immersion in a virtual environment. Data analysis methods are described, and experiments associated with classification of mental states during listening exercises as well as audio-visual stimuli are presented and discussed. Feature extraction was based on discrete wavelet transformation and clustering employing the k-means algorithm was designed. All algorithms were implemented in the Python programming language with the use of Open Source libraries. Tests of the proposed system were performed in a Special School and Educational Center in Koś-cierzyna, Poland. Results and comparison with data gathered from the control group of healthy people are presented and discussed.

Multi-objective optimization for assessment of topological modification in UWB antennas
- Adrian Bekasiewicz
- Sławomir Kozieł
This paper addresses an issue of systematic and rigorous assessment of effects of topological modifications on the performance of compact UWB antennas. Application of fast surrogate-assisted multi-objective optimization procedures allows us for obtaining, in a practically acceptable timeframe, a set of designs representing the best possible trade-offs between conflicting objectives (here, antenna size minimization and reduction of the maximum in-band reflection level). Comparison of such Pareto-optimal sets of designs for different variations of the same antenna structure permits for conclusive assessment of the usefulness of particular geometry modifications.

Multi-objective weather routing of sailing vessels
- Marcin Życzkowski
- Rafał Szłapczyński
The paper presents a multi-objective deterministic method of weather routing for sailing vessels. Depending on a particular purpose of sailboat weather routing, the presented method makes it possible to customize the criteria and constraints so as to fit a particular user’s needs. Apart from a typical shortest time criterion, safety and comfort can also be taken into account. Additionally, the method supports dynamic weather data: in its present version short-term, mid-term and long-term term weather forecasts are used during optimization process. In the paper the multi-objective optimization problem is first defined and analysed. Following this, the proposed method solving this problem is described in detail. The method has been implemented as an online SailAssistance application. Some representative examples solutions are presented, emphasizing the effects of applying different criteria or different values of customized parameters.

Multiple output second-generation current conveyor utilizing high frequency output stage
- Bogdan Pankiewicz
In this paper a multiple output second-generation current conveyor (MOCCII) is presented. The main advantage of the proposed general circuit architecture over a typical structure, well known in the literature, is the use of a high passband multiple output current mplifier block instead of cascaded current mirrors. It gives similar frequency responses for all the outputs of the current conveyor and also maintains simplicity of the whole circuit. As an example, a detailed design of the MOCCII in 350nm CMOS process is presented. The conveyor consumes only 135uA from 3.3V power supply and exhibits over 120MHz of 3dB passbands for both positive and negative outputs.

Museum Institutions in Monuments - Positive and Negative Aspects of Adaptation: The New Amber Museum and Museum of Science in Gdansk, Poland
- Ksenia Piątkowska
The issue of the creation and location of new museums is a current topic. The decision of where and how to create new museum facilities will impact successful function in the future. Museums are either located in newly designed buildings or in existing buildings. In general, existing buildings adapted for museum use are either formally under conservational protection or not. With regard to museum location in preserved monuments, the author notes that the true impact on authentic monumental building structure still needs intense research. The adaptation of the Great Mill and St. Catherine’s Church - two preserved medieval objects located in the historical city center of Gdansk - provide case studies to investigate positive and negative aspects. In both cases, the author carried out architectural projects for the functional purposes of museums: the New Amber Museum and Museum of Science. The author concludes that mutual benefits of adaptation result from: the financial means of the museum institution to invest long-term; the institutional respect of the museum towards heritage, which translates into respect for conservational protection; and the competitive advantage created by the monumental features of the building and the privileged location in a well-established, branded space. Negative aspects result from: space limitations of monuments that disable the museum from extending its exposition and thus prevent institutional development; the overly restrictive requirements of restoration that take priority over the museum mission; and the lack of technically functional space required for contemporary museum technologies, which forces unconventional engineering solutions that are more expensive than the location of the museum in a newly constructed building.

Museum of the Second World War in Gdansk as an Example of Contemporary Design Trends in Museum Buildings
- Dorota Wojtowicz-Jankowska
- Anna Stasiak
At a time when history gives us one of the last opportunities to confront our knowledge of World War II, with the knowledge of people living in those days, there are buildings created with strong transmission not only architectural, but also of a great emotional load. At the same time, when the political system does not forbid to speak openly about the past period, and the technology allows you to create structures, about which we could only dream of even several dozen years ago, and objects such as the Museum of the Second World War in Gdansk are designed. In this paper are presented the current trends shaping the museum facilities, with the example of the Museum of the Second World War . The diversity of forms, materials and technology makes it impossible to establish a single standard for this type of public buildings, and that makes each of these objects unique. At the same time it is possible to identify some common spatial treatments noted in the sector of architecture devoted to exhibitions and commemoration. The Museum of the Second World War is a newly created structure, in the design of which the authors used advanced technology (which allows the implementation of its ideas) in order to meet the ever-growing needs of users. The popularity of museums depends on many factors, such as the type and form of the offered exhibitions, the transfer of information and emotional value, location of the building and adaptation of the facility to the users' needs, which differ in many respects (age, the efficiency of perception , education or wealth). Given that museums are usually buildings that have noticeable form in the urban landscape, the paper will describe how to set up the idea, and later its implementation, impact on urban space. Additionally for some time exhibitions and architecture surrounding them have become a tool for the promotion of towns, regions, or even the whole countries. The fact is that the exhibitions are visited not only by local residents but also by tourists. If the museum is well integrated into the urban spatial structure (landscape), it has a good chance to become one of the symbols of the city. Additionally, it can promote creating and deepening the sense of identity of the local users’ public space.

Museums of Gdansk - Tourism Products or Signs of Remembrance?
- Dorota Wojtowicz-Jankowska
Museum buildings constitute a significant element in the composition and functionality of contemporary cities. They are both their attractions and landmarks. The article presents a case study illustrating the relation between museum buildings and their location, as well as the showcased exhibition. The article aims at demonstrating the way in which those elements form a harmonious whole - a cultural tourism product affecting the economics of the region. In the context of perceiving a museum as an element shaping the dynamics of tourism development, the location planned for the museum is not without significance. Enhancing the popularity of a city on the basis of the existing museums has become a common phenomenon and is viewed as a driving force of museum tourism development. Sometimes, the museum building itself is considered as one of the elements adding to the attractiveness of the city. The relationship between the exhibition as such and the location - the city - is not the most important factor. Gdańsk is an example of a city which contradicts that approach. Four new museum seats built in the 21st century serve to demonstrate how interesting it may be to seek the right architectural form of museums for the places where they are erected. Furthermore, the thematic scope of exhibitions is strictly related to the history of the place. Particularly worthy of attention are the National Maritime Museum, the European Solidarity Centre and the Museum of the Second World War. The examples discussed in the article prove that the value of a place as such in displaying the building and the museum collections is significant. It is impossible to disregard that connection, if the city aims at promoting not only the architectural form of the museum building, but also the exhibits, especially if they are related to its history. Gdańsk is an example of a place with museum buildings of interesting architectural forms which are not only style icons, but also unique symbols commemorating events important in the history of the city.
