Data acquisition in process industries usually takes place at each sampling. The disadvantage is that a considerable amount of data without new information about the state of the process is continuously transmitted and processed. This negatively affects the communication system and computational power, which is more critical nowadays given the number of variables measured, even in seconds. One solution concerns the event-driven paradigm, in which only relevant data according to a pre-defined criterion is forwarded for further processing. This work investigated the event-based threshold and delta methods in the context of fault detection. The data transmission rate was also analyzed. The well-know Tennessee Eastman problem (TEP) was used as a case study. The fault detection system was based on PCA (principal component analysis), which is widely used for this purpose in this benchmark. The results were compared with the commonly used time-based approach, for a fixed false alarm rate. The threshold rule provided similar results, but with much less data. For the delta rule, significant MDR (missed detection rate) gains of up to 74% were obtained for five of the six hard-to-detect faults, and of up to 69%, for two of the three very hard-to-detect faults. MDR values very close to zero were reached for two of the three intermediate detection faults and two of the hard-to-detect faults. The detection time was also evaluated. In this regard, considerably lower values were obtained for all intermediate detection faults, three of the hard-to-detect faults and all very hard-to-detect faults. In short, the delta method was able to improve fault detection performance, especially for hard-to-detect faults, with a considerably lower data transmission rate, around 20% on average. Event-driven data acquisition can be very attractive for process industries.

Figure 1. Our method obtains a high-quality 3D reconstruction from an RGB-D input sequence by training a multi-layer perceptron. In comparison to state-of-the-art methods like BundleFusion [3] or the theoretical NeRF [9] with additional depth constraints, our approach results in cleaner and more complete reconstructions. As can be seen, the pose optimization of our approach is key to resolving misalignment artifacts.

Nowadays, when operating in an unstable market, organizations in Bosnia and Herzegovina (BiH) are also facing a continuous outflow of qualified employees to the countries of the European Union. In order to properly respond to the challenges from the environment, the organizations in BiH are forced to take adequate measures so as to become competitive in the market, which may prove to be difficult if they do not retain skilled workforce. This paper attempts to show that by implementing appropriate human resource management (HRM) practices and policies, organizations in BiH can affect employee organizational commitment, which will result not only in market survival but also in increased competitiveness, as the experience of the organizations in the surrounding countries shows that human resources is what gives these companies a competitive advantage. The paper aimed at examining the impact of characteristics, organizational characteristics, and HRM practices focused on performance appraisal, job security, employee participation, and career planning on employee organizational commitment in BiH companies with more than 50 employees in four sectors. The empirical research was conducted on a sample of 128 companies. The results show that when it comes to employee organizational commitment, HRM practices and policies bear more importance than demographic and organizational characteristics and that there is a statistically significant positive impact of HRM practices and policies on employee organizational commitment.

Like any crisis in the human world, the migrant crisis can be approached without more comprehensive interpretations and deeper understanding. Nevertheless, recognizing intuitions at the first observations of European and Balkan "migrant events" is prudent, and beyond prejudice and pre-understanding, to search for the causes of the crisis. The ongoing migrant crisis has highlighted the need to create and implement a multidisciplinary model of understanding the 21st-century conflict. Models used so far halved from mega authorial theories and political doctrines, such as various pro-globalization or anti-globalization approaches, transitional neoliberal formulas, the pattern of "new world order," or "clash of civilizations," clashes of religions and cultures, world system, post-imperialism, various postmodern theories, doctrines of so-called soft and hard power, they have proven to be incompliant to events and therefore insufficient for a complete understanding of the contradictions and contradictions of the modern world. Historically, the current migrant crisis has regained the importance of questioning the spatial dimensions of the European populist configuration. The current and previous migrant problems have reminded classical and contemporary geopolitical theories of the original understanding of this approach to social and political phenomena, long overdue by Rudolf Kjellen. In one of the earliest divisions of geopolitics, a deserved place was found by demo politics. The focused demo-political reflection gains importance in situations of growing demographic problems. While geopolitics primarily encompasses processes of changes in space and area, demo politics touch on politically conditioned processes in the population. In seemingly chaotic demo politics, it reaffirmed the importance of a critical geopolitical interpretation of migrant processes. Even among the pro-non Eurocrats, for various ideological reasons, extremely inclined to specific geopolitical ideas and arrangements, it strengthened the sense of continental spatiality, accompanied by the knowledge that geopolitics "after all" has returned to European and world relations. In addition to many crises that have befallen Europe, the return of geopolitics has been contributed by the disruption sustained by the migrant wave. The current migrant crisis is a causal-consequential crisis, which means that as an already emerging disorder, it causes many other diseases that would not be without its effect. Still, it is also caused by factors that have previously shaped it and may not be known enough until this moment. The driving and emergence of the migrant crisis have occurred in the past; its modern development encompasses the present, and, likely, the migrant crisis will be faced by Europe in the future. Hence, it is necessary to bear in mind the concrete historical dimension of the problem, which also contains specific chrono-political components. When something is not understood as before at one time, the development usually enables that if it is to be understood in the consequential time.

Bosnia and Herzegovina is a country with a very high risk of floods, which is documented in Vulnerability assessment, where it is defined that "floods represent the greatest danger for community and its population". Due to climate changes in recent decades, floods have become one of the most serious forms of threat to the population and material assets. After signing the Stabilization and Association Agreement with the EU in 2008, BiH accepted obligation to harmonize its legislation with the EU acquis communautaire, which also includes water legislation. The complex constitutional arrangement and unfavorable socio-economic situation make it difficult to fulfill assumed obligations, as well as protection and rescue system normal functioning on state territory. This research subject is protection and rescue system analysis, assessment of the adequacy of existing measures and current flood risk management techniques in BiH through a comparative analysis with practice of flood risk management in the EU.

In this letter, we study the trade-off between exploration and exploitation for linear quadratic adaptive control. This trade-off can be expressed as a function of the exploration and exploitation costs, called cumulative regret. It has been shown over the years that the optimal asymptotic rate of the cumulative regret is in many instances $\mathcal {O}(\sqrt {T})$ . In particular, this rate can be obtained by adding a white noise external excitation, with a variance decaying as $\mathcal {O}(1/\sqrt {T})$ . As the amount of excitation is pre-determined, such approaches can be viewed as open loop control of the external excitation. In this contribution, we approach the problem of designing the external excitation from a feedback perspective leveraging the well known benefits of feedback control for decreasing sensitivity to external disturbances and system-model mismatch, as compared to open loop strategies. We base the feedback on the Fisher information matrix which is a measure of the accuracy of the model. Specifically, the amplitude of the exploration signal is seen as the control input while the minimum eigenvalue of the Fisher matrix is the variable to be controlled. We call such exploration strategies Fisher Feedback Exploration (F2E). We propose one explicit F2E design, called Inverse Fisher Feedback Exploration (IF2E), and argue that this design guarantees the optimal asymptotic rate for the cumulative regret. We provide theoretical support for IF2E and in a numerical example we illustrate benefits of IF2E and compare it with the open loop approach as well as a method based on Thompson sampling.
