    Opis:
    The article presents an analysis of the use of a single-board computer Raspberry PI for video acquisition and transmission. The article focuses on requirements necessary for the recorded image to be used for face analysis to identify facial expressions and microexpressions. The quality of the recorded video frames was verified for different resolutions and fps using PSNR (Peak Signal-to-Noise Ratio). Tests of CPU cores usage were also carried out for simultaneous recording and transmission of different types of video streams. The results show that the size of the effective image area depends on the resolution of recorded video stream. Increasing the frame rate for the given video resolution has a significant impact on the value of PSNR. And the resultant CPU usage, for the available resolutions and frame rates of the video recorded, in most cases does not exceed 15% of the total computing power of the CPU.

    Opis:
    A pocket-size binaural speech segregation system has been developed and assembled with available consumer hardware. It can enhance a target speech in a certain direction while attenuating interfering sounds from other directions. This system is based on the frequency domain binaural model (FDBM) and it segregates multiple speeches based on the directivity. This real-time system is implemented on a low-cost single board computer which might be used as a hearing assistance device. Performance of the system is evaluated in a normal laboratory room as well as anechoic chamber. Even in a room with reverberation, the system works well and show the almost same performance obtained in anechoic chamber.

    Opis:
    Dissenting opinions to the rulings of state bodies are submitted very rarely. The purpose of this article was to identify the reasons for this phenomenon in case of rulings of collegial public finance bodies, such as committees adjudicating on cases of violation of public finance discipline (including joint adjudication committee, inter-ministerial adjudication committee, adjudication committee at the Chief of Staff of the Prime Minister Chancellery, regional adjudication committees at regional accounting chambers, the Main Adjudication Committee) and rulings of local government appeal boards adjudicating on tax matters. The research was conducted using the Computer-Assisted Web Interview research technique. The research material included 67 questionnaires completed by a group of employees-adjudicators of the above-mentioned bodies. Their analysis led to the following research findings which explained why dissenting opinions to the decisions of collegial public finance authorities are submitted so seldom: rare occurrence of controversies among the members of the adjudicating panel, personality traits of the members of these bodies, and more specifically, striving to ensure their independence and a sense of collegiality. The shape of the procedural provisions governing the rules for submitting dissenting opinions cannot be seen as one of such reasons.

    Opis:
    The topic of the MA dissertation embraces the field of computer mediated language learning applied in the English classroom. The author’s goal is to discover the effects of the multimedia use in foreign language teaching. The background of computer enhanced language learning has been developing dynamically for the last decades and numerous technological possibilities have been introduced that influence the learning process. Having analysed the history of technology enhanced classroom thoroughly it is obvious that multimedia offers numerous opportunities for learners of foreign languages regardless of their age, learning styles, the level of difficulty. Owing to the thorough literature review it became possible to learn about and understand the use of multimedia tools as well as their implications for its future. The dissertation is divided into four parts, three of which present theory regarding Computer Assisted Language Learning based on professional and scientific literature review, one chapter is empirical, devoted to the conducted survey.

    Opis:
    One of the most important features of the Advanced Telecommunications Computing Architecture (ATCA) contributing to its exceptional reliability and availability is its hot-swap functionality. In order for the user to be able to add and remove the components of an ATCA shelf without the necessity of switching the power on and off the PCI Industrial Computer Manufacturers Group (PICMG) specification clearly enumerates the stages a Field Replaceable Unit (FRU) has to go through upon insertion into and extraction from the shelf. These stages form the activation and deactivation processes that occur every time an element is changed in the ATCA system. This paper focuses on these processes placing the emphasis on the Electronic Keying (EK) implementation in the Intelligent Platform Management Controller (IPMC) software developed for the self-designed ATCA Carrier Board (CB). This CB is considered to be used in the Low Level RF (LLRF) control system of the X-Ray Free Electron Laser (XFEL). It utilizes the standard-defined PCI Express (PCIe) interface as well as introduces proprietary protocols in form of Low Latency Links (LLL).

    Opis:
    During archaeological excavations in Nowy Łowicz, Pomerania (Poland), in 1991, burial mound 55 with a woman’s grave was examined, in which numerous fragments of textiles, costume accessories and jewellery had been preserved. The work presents the results of structural and technological analysis of fragments preserved. Based on these, as well as on preserved iconography and analogous archaeological finds, an attempt was made to reconstruct the woman’s clothing from the period to which the grave is dated, i.e. phase B2/C1 of the Roman period. The reconstruction was made by means of computer graphics and includes three elements of clothing: a shirt, dress and short coat, made by identified techniques and partly taking into account the original colours. The work done is particularly important due to the fact that this is the first attempt to reconstruct a woman’s complete clothing worn on the territory of what is now Poland in the above-mentioned period.
    Podczas wykopalisk archeologicznych w Nowym Łowiczu na Pomorzu w 1991 roku zbadano kurhan 55 z grobem kobiecym, w którym zachowały się liczne fragmenty tkanin, ozdób i biżuterii. W pracy przedstawiono wyniki analizy strukturalnej i technologicznej zachowanych fragmentów tkanin. Na ich podstawie, a także na podstawie ikonografii i analogicznych znalezisk archeologicznych podjęto próbę zrekonstruowania ubioru kobiecego z okresu, w którym datowany jest grób, tj. fazy B2/C1 okresu rzymskiego. Rekonstrukcja została wykonana za pomocą grafiki komputerowej i obejmuje trzy elementy ubioru: koszulę, suknię i krótki płaszcz, wykonane w zidentyfikowanych technikach i częściowo z uwzględnieniem oryginalnych kolorów. Wykonana praca jest szczególnie ważna, ponieważ była to pierwsza próba rekonstrukcji kompletnego ubioru kobiecego noszonego w okresie rzymskim na terytorium dzisiejszej Polski.
