    Opis:
    The development of advanced spatial-positioning and monitoring systems for medical monitoring and emergency response using RFID & Wi-Fi technologies is a large-scale research project being conducted at the ward W21C of Foothills Hospital, Calgary, Canada by University of Calgary. The scope of this project is to support real-time location tracking of medical equipments and personnel in hospital settings. In this context, we developed an innovative, interactive, decision-support medical system for tracking of personnel and high value medical equipments. The goal behind development of such a system is to provide a convenient, easy to use interface using existing technologies that allows to visualize and analyse clinical pathways and health care provider’s workflow pattern as well as to perform time motion studies and more advanced statistical pattern analysis. While achieving this goal, we aim to also fill the existing void of documentation and present to scientific community functional issues encountered along with their importance in success.

    Opis:
    The essay faces up to the topic of “crisis” from the perspective of historical and sociological semantics. Troublesomeness of the crisis is a permanent fixture in any philosophy of historical time. An author sees a social reality as flows of social practices with their symbolic and material effects and assumptions, in the same breath. The subject of his considerations are selected representative theories and ideologies of “crisis” with their assumptions pertinent to philosophies of time and time politics. Considerations of the author refer to the semantic struggles in the field of “crisis” sociology. Conclusions are also referred to the epistemic standpoint of the sociology of security and its subjects matter, the vicious circle of fear, anxiety, and secular Providences in political projects of the future time.

    Opis:
    Introduction Adolescence is marked as a critical period of human life because of the rapid physical and sexual growth. Technological advances in recent decades have increased the interaction of adolescents with screen-based technologies. The adolescents have the unhealthiest diets of all age groups, and most adolescents do not meet the national guidelines for physical activity. Objectives: To assess physical activity, dietary pattern and screen time among urban adolescents and to find out association of Screen Time with different variables. Methods A cross sectional study carried out in Udaipur, Rajasthan with prior permission from ethical committee. The study included 250 adolescents (10 to 19 years) selected by multistage sampling method. The Leisure Time Exercise Questionnaire of Godin and Shephard was used to find out weekly Physical Activity score. Eating habits were investigated using self-administered questionnaire in which we asked different questions about the food consumed by adolescents in a week. A Screen Time of ≥2 hours/ day was categorized as high sedentary behaviour, whereas a Screen Time <2 hours/ day was categorized as low sedentary behavior. Results In current study prevalence of High Screen Time and unhealthy diet was around 83% and 60% respectively. Around 25% had habit of taking breakfast regularly while less than 30% were taking meal without fail. Screen Time found to be associated significantly with physical activity p < 0.01, gender (p = 0.01) and diet p < 0.01. Conclusion Screen Time was found to be associated significantly with physical activity, gender and type of diet, whereas it has no role to play with phases of adolescence.

    Opis:
    Sequential pattern mining is an extensively studied method for data mining. One of new and less documented approaches is estimation of statistical characteristics of sequence for creating model sequences, that can be used to speed up the process of sequence mining. This paper proposes extensive modifications to one of such algorithms, ProMFS (probabilistic algorithm for mining frequent sequences), which notably increases algorithm's processing speed by a significant reduction of its computational complexity. A new version of algorithm is evaluated for real-life and artificial data sets and proven to be useful in real-time applications and problems.

    Opis:
    Time-Frequency (t-f) distributions are frequently employed for analysis of new-born EEG signals because of their non-stationary characteristics. Most of the existing time-frequency distributions fail to concentrate energy for a multicomponent signal having multiple directions of energy distribution in the t-f domain. In order to analyse such signals, we propose an Adaptive Directional Time-Frequency Distribution (ADTFD). The ADTFD outperforms other adaptive kernel and fixed kernel TFDs in terms of its ability to achieve high resolution for EEG seizure signals. It is also shown that the ADTFD can be used to define new time-frequency features that can lead to better classification of EEG signals, e.g. the use of the ADTFD leads to 97.5% total accuracy, which is by 2% more than the results achieved by the other methods.

    The development of advanced spatial-positioning systems for medical monitoring and emergency response using RFID and Wi-Fi technologies is a current research focus of many healthcare organizations. The goal of such system is to support real-time location tracking of medical equipments and personnel in hospital settings using RTLS technology. This paper presents a spatial-temporal data analysis based on data collected at the W21C of Foothills Hospital, Calgary, Canada. The collected data, comprising real-time observations and tracking paths, has been used to perform advanced statistical pattern analysis and visualization of work-flow patterns in health care system. From this analysis, we bring forward some insights into medical resource, asset and facility utilization in a clinical care ward of a regional healthcare organization. This gained knowledge could be used as one of the inputs in improving patient care, responsiveness, and infection control practices.

    Opis:
    A variety of algorithms allows gesture recognition in video sequences. Alleviating the need for interpreters is of interest to hearing impaired people, since it allows a great degree of self-sufficiency in communicating their intent to the non-sign language speakers without the need for interpreters. State-of-the-art in currently used algorithms in this domain is capable of either real-time recognition of sign language in low resolution videos or non-real-time recognition in high-resolution videos. This paper proposes a novel approach to real-time recognition of fingerspelling alphabet letters of American Sign Language (ASL) in ultra-high-resolution (UHD) video sequences. The proposed approach is based on adaptive Laplacian of Gaussian (LoG) filtering with local extrema detection using Features from Accelerated Segment Test (FAST) algorithm classified by a Convolutional Neural Network (CNN). The recognition rate of our algorithm was verified on real-life data.

    Opis:
    Cotton genotypes H-6, H-4 (Gossypium hirsutum L.) and V797 (Gossypium herbaceum L.) were analyzed for fruiting pattern (i.e. distribution of flowers, numbers of bolls and its dry weight on different branches) and percent (%) dry matter partitioning into the different components of the boll (seed, fiber and boll wall). Percent distribution of flowers, bolls and dry weight within the plant varied distinctly among the genotypes studied. In higher yielding genotypes (H-4 and H-6), during the initial stage of plant growth for about 10 days, 60-80% of dry matter was partitioned into boll wall and decreased up to 12-15% as the boll developed (nearly 45 days). Contrary to this, seed and fiber accumulated dry matter during development (60-75%). Abscission rate increased with an increase in boll load in all three genotypes and it was significantly higher in the lower yielding variety, V797. A reduction in boll and seed number, seed and fiber dry weight was observed with the progress in the season and was significantly higher in V797 as compared to H-4 and H-6.

    Opis:
    The aim of this paper was to determine the mechanisms of climate change impact on the yield of the main exportoriented crops in the agro-climatic zones of Ukraine. The study of the problem of changing the acreage of the main export-oriented crops was conducted according to the data of the State Statistics Service of Ukraine on the time horizon 2000-2018 in the following order: first, the dynamics of the change of the acreage under corn, sunflower and wheat by the agro-climatic zones of Ukraine was analyzed; secondly, the trends of yield changes of these crops were investigated based on the increase in the difference in yields between the northern and southern zones; and, finally, the temporal and spatial expansion in the area of crop propagation were investigated by applying the panel regression method. The findings obtained indicate that the applied models confirm the assumption of the effects of climate change on crop yield changes and the zones expansion in the northern direction. If the country’s wheat area can be considered stable (variation is insignificant), then the corn and sunflower areas have grown steadily under the influence of increasing demand from national and world markets. At the same time, the growing acreage under corn and sunflower occurred in all climatic zones. Stable expansion of corn crops in the north direction in all three agroclimatic zones of Ukraine has been statistically confirmed. The article presents the findings of empirical analysis, which confirm that if the boundaries of soil and climatic zones change, the conditions of growing crops and their yield will consequently change as well. Thus, based on current global forecasts, the impact of weather on Ukraine’s agriculture will increase, and the most negative effects can be expected in the Steppe zone, where the likelihood of weather and climate risks increases, requiring the development of adaptation and mitigation measures as well as exploitation of new potential opportunities that are being opened. Studies have shown that there is an expansion in crops to the north and a change in their pattern, including a significant increase in the area under corn.

    Opis:
    A new supervised classification algorithm of a heavily distorted pattern (shape) obtained from noisy observations of nonstationary signals is proposed in the paper. Based on the Gabor transform of 1-D non-stationary signals, 2-D shapes of signals are formulated and the classification formula is developed using the pattern matching idea, which is the simplest case of a pattern recognition task. In the pattern matching problem, where a set of known patterns creates predefined classes, classification relies on assigning the examined pattern to one of the classes. Classical formulation of a Bayes decision rule requires a priori knowledge about statistical features characterising each class, which are rarely known in practice. In the proposed algorithm, the necessity of the statistical approach is avoided, especially since the probability distribution of noise is unknown. In the algorithm, the concept of discriminant functions, represented by Frobenius inner products, is used. The classification rule relies on the choice of the class corresponding to the max discriminant function. Computer simulation results are given to demonstrate the effectiveness of the new classification algorithm. It is shown that the proposed approach is able to correctly classify signals which are embedded in noise with a very low SNR ratio. One of the goals here is to develop a pattern recognition algorithm as the best possible way to automatically make decisions. All simulations have been performed in Matlab. The proposed algorithm can be applied to non-stationary frequency modulated signal classification and non-stationary signal recognition.
