    Opis:
    Facial feature analysis is a basis examination in everyday orthodontics practice. Traditionally it was carried out using the patients photographs and callipers. Although the devices for scanning 3D surfaces have been developed since last decade of XX century their use in supporting orthodontics diagnosis have been limited due to availability and prices. The present work examine the possibility of usage of the 3D surface scanning for orthodontics purposes using professional graphic tool RapidForm. The landmarks-based analysis of facial features and asymmetry of soft tissue is described. Possibilities of surface-based analysis are also illustrated and their limitations are discussed.

    Opis:
    Over the last two decades, facial symmetry has been intensively researched. The present article aims to summarize empirical research concerning relations between facial symmetry and health and facial symmetry and personality. A systematic review of the literature shows that facial symmetry is one of the most influential visual markers of attractiveness and health, important for mate selection, while asymmetry can be considered a consequence of an individual’s inability to resist environmental and genetic stressors during development of the organism. However, in spite of evidence suggesting that preferences for facial symmetry are deeply rooted in our evolutionary history, a strong connection between facial symmetry and health is demonstrated only in studies measuring perceived health, while there is only scarce evidence corroborating the link between symmetry and actual health. The interconnections between facial symmetry and personality have not yet been extensively researched. Less than a dozen studies have addressed that issue and they have reached different conclusions. Some evidence suggests that facial symmetry signals personality attributes that indicate good psychological health, while other findings imply that pro-social personality traits negatively correlate with facial symmetry.

    Opis:
    In day to day stressful environment of IT Industry, there is a truancy for the appropriate relaxation time for all working professionals. To keep a person stress free, various technical or non-technical stress releasing methods are now being adopted. We can categorize the people working on computers as administrators, programmers, etc. each of whom require varied ways in order to ease themselves. The work pressure and the vexation of any kind for a person can be depicted by their emotions. Facial expressions are the key to analyze the current psychology of the person. In this paper, we discuss a user intuitive smart music player. This player will capture the facial expressions of a person working on the computer and identify the current emotion. Intuitively the music will be played for the user to relax them. The music player will take into account the foreground processes which the person is executing on the computer. Since various sort of music is available to boost one's enthusiasm, taking into consideration the tasks executed on the system by the user and the current emotions they carry, an ideal playlist of songs will be created and played for the person. The person can browse the playlist and modify it to make the system more flexible. This music player will thus allow the working professionals to stay relaxed in spite of their workloads.

    Opis:
    The author attempts at formulating a synthetic description of geological and geomorphological effects of theWartanian ice-sheet deglaciation in the eastern part of the Łódź region, taking their spatial variability into consideration. Characteristic features of Wartanian Glaciation sediments occur in this area, and their lithofacial diversity and spatial distribution needed interpretation. The deposits document the complex processes of deglaciation, which developed here across an unusually broad area in the scale of the Polish Lowland. The best developed deglaciation sediments occur in the eastern part of the Łódź Heights, between the Mroga and Rawka rivers, as structural components of different types of kames and glaciofluvial covers. In locations where glacial till is elevated they include mainly sediments of braided rivers and alluvial cones, whereas in areas of wide depressions of till and, thus, of the ice-sheet bedrock — glaciolimnic sediments prevail. The highest and most diverse western part of the Łódź Heights is characterised by the occurrence of thin and discontinuous deglaciation sediments, because this area was shaped mainly during the ice-sheet transgression. During deglaciation, ablation waters left mainly traces of erosion, whereas the glaciofluvial accumulation series are not well developed. In the Rawa Interfluve, deglaciation sediments accumulated predominantly at the early deglaciation stage in sparesely distributed broad basins of kame sedimentation. In the Piotrków Plain, deglaciation deposits are thin; ice-sheet disintegration proceeded without major blockages of ablation waters, resulting in a less diverse interfluvial landscape.

    Opis:
    This article describes guidelines and recommendations for acquisition of databases for facial analysis. New devices and methods for both face recognition and facial expression recognition are constantly developed. In order to evaluate these devices and methods, dedicated datasets are recorded. Acquisition of a database for facial analysis is not an easy task and requires taking into account multiple issues. Based on our experience with recording databases for facial expression recognition, we provide guidelines regarding the acquisition process. Multiple aspects of such process are discussed in this work, namely selection of sensors and data streams, design and structure of the database, technical aspects, acquisition conditions and design of the user interface. Recommendations how to address these aspects are provided and justified. An acquisition software, designed according to these guidelines, is also discussed. The software was used for recording an extended version of our previous facial expression recognition database and proved to both ensure correct data and be convenient for the recorded subjects.

    Face plays significant role in social communication. This is a 'window' to human personality, emotions and thoughts. Due to this, face is a subject of study in many areas of science such as psychology, behavioral science, medicine and computer science etc. In this paper, a comparative study is suggested between CS-LBP/SVM and CS-LBP/PCA. These algorithms are used in emotive facial expression recognition. Finally, a comparison is shown between PCA & SVM in terms of Dimension Reduction. The proposed system uses grayscale frontal face images of a Japanese female to classify six basic emotions namely happiness, sadness, disgust, fear, surprise and anger.

    Opis:
    The Late Cretaceous to Oligocene strata of the Dukla Nappe, which is a part of the accretionary wedge formed in front of the Carpathian orogen, record a history of the basin development from remnant to foreland basin stages. The lower part of the succession indicates the first stage of basin evolution characterized by turbidite systems fed from the E (NE) to W (SW). The system encompasses deposits of the Łupków and Cisna formations deposited in a channel-lobe transition (Łupków Fm.) and in sandstone-rich channelized lobes (Cisna Fm.) The transitional phase is represented by deposits of the Submenilite Formation derived from two different sources (SE and N) and deposited in a submarine slope/ramp environment. The third stage of basin evolution is marked by the advancing front of the Carpathian orogen resulting in peripheral foreland basin development. Increased tectonic activity led to a switch in sediment source from the SE to the NW, more complex topography of the basin and a change in sediment distribution. The initial phase of this stage is characterized by low-density turbidites and suspension fall-out sediments of the Menilite Fm. Discrete tectonic pulses are recorded by the thick Cergowa sandstones, mostly deposited by hybrid flows and high-density turbidity currents. A decrease in tectonic activity is suggested by heterolithic deposits of the Krosno Fm. capping the sedimentary succession.

    Opis:
    Badanie doświadczeń klienta wymaga rozwijania metodyki ich pomiaru pozwalającej na uwzględnienie ich złożoności. Jedną z ważnych składowych doświadczeń są emocje, których rozpoznawanie i pomiar stanowi wciąż wyzwanie dla badaczy. Celem artykułu jest dyskusja na temat metod i technik wykorzystywanych do rozpoznawania i pomiaru emocji w badaniach doświadczeń klienta. Szczególną uwagę poświęcono wykorzystaniu technik wywodzących się z neuronauki konsumenckiej, w tym dylematom związanym z sięganiem po automatyczną analizę ekspresji mimicznej. Studia literaturowe pozwoliły na dyskusję dotyczącą korzyści i ograniczeń stosowania automatycznej analizy ekspresji mimicznej w pomiarze doświadczeń klientów. Mimo ograniczeń, mogą one być traktowane jako atrakcyjne uzupełnienie metod i technik pozwalających na uchwycenie emocjonalnych komponentów doświadczenia klienta na różnych etapach (przed zakupem, w jego czasie i po nim).
    The study of customer experience requires the development of methodologies which measure such experience and account for its complexity. One important component of customer experience is emotion, the recognition and measurement of which is still a challenge for researchers. The purpose of this article is to discuss methods and techniques used to recognise and measure emotions in customer experience research. Particular attention is paid to the use of techniques derived from consumer neuroscience, including the dilemmas associated with reaching for automatic analysis of facial expressions. The literature review is indicative of the ongoing discussion on the benefits and limitations of using the automatic analysis of facial expressions technique in measuring customer experience. Despite its limitations, such a technique can be an attractive complement to methods and techniques used to capture the emotional components of customer experience at different stages (before, during, and after purchase).
