Supervision of repair and diagnostic works aimed at improving the safety of maintenance crews is one of the key objectives of the distributed INRED system. Working in a real industrial environment, ...the INRED system includes, among others, the so-called INRED-Workflow, which provides an infrastructure for process automation. Participants of the service processes, managed by the INRED-Workflow, are controlled at each stage of the performed service procedures, both by the system and other process participants, such as quality managers and technologists. All data collected from the service processes is stored in the System Knowledge Repository (SKR) for further processing by using advanced algorithms, and the so-called
Smart Procedures
merge services supplied by other INRED system modules. The applicability of workflow management systems in conjunction with image recognition and machine learning methods has not yet been thoroughly explored. The presented paper shows the innovative usage of such systems in the supervision of the repair and diagnostic works.
Air pollution is one of the main factors affecting human health. Air quality is especially important in the tourist areas developed with facilities for outdoor activities. During the winter season of ...2017/2018, the concentrations of particulate matter (PM10, PM2.5, PM1), CO, O3, and NO2 were studied in 12 attractive tourist villages in the surroundings of the Czorsztyn Reservoir in southern Poland. Air pollutant measurements were performed continuously, using a single ground-based Alphasense air sensor. Our assessment of human health risk (HHRA), arising from inhalation exposure to air contaminants, was calculated for both local inhabitants and tourists, based on actual measured values. It was found that pollutant concentrations exceeded both permissible and recommended levels of PM10 and PM2.5. The mean total noncarcinogenic risk values were equal to 9.58 (unitless) for adults and 9.68 (unitless) for children and infants, under the resident exposure scenario. However, under the tourist exposure scenario, the mean total risk was equal to 1.63 (unitless) for adults and 1.64 (unitless) for children and infants. The risk to tourists was lower than that to inhabitants due to shorter exposure times. The target non-carcinogenic value of 1, calculated for PM10, PM2.5, and NO2, was significantly exceeded in total risk, under the residential exposure scenario, in reference to all the local subpopulations. In the majority of the investigated locations, the total risk exceeded the value of 1, under the tourist scenario, for all the subpopulations analysed. PM2.5 was recognised to be the most important contaminant in our risk analysis, in view of its share in the total risk value.
The aim of this study was to assess air quality by using medium-cost sensors in recreational areas that are not covered by permanent monitoring. Concentrations of air pollutants PM2.5, PM10, PM1, CO, ...O 3 , NO 2 in the Niedzica recreational area in southern Poland were obtained. The research revealed that in cold weather, particulate matter concentrations significantly exceeded acceptable levels determined for PM2.5 and PM10. The most important factor that affects air quality within the studied area seems to be the combustion of poor quality fuels for heating purposes. The information obtained by the research presented could be a useful tool for local authorities to make environmental decisions, based on the potential health impacts of poor air quality levels on the population.
•We have adapted the Social Force Model for skiing traffic.•We have introduced way-point forces, neighbor repulsion forces, obstacle repulsion forces and slope edge repulsion forces•We have described ...and implemented the whole system including ski routes as well as ski lifts.•We have developed a tool for setting up a ski route on a 3D terrain model.
This paper describes an agent-based model of downhill skiing traffic. Our main purpose is research into skiers’ physics and behavior modeled with the use of a modified social force approach. The proposed model includes the following social forces: way-point forces – directing a skier towards consecutive way-points on the slope, skiers’ repulsion forces – keeping distance between skiers using a concept of skier's social ellipses, obstacle repulsion forces – keeping skiers away from obstacles, and slope edge repulsion – keeping a skier along the slope route using repulsion force inspired by Biot–Savart law. The proposed model also includes additional behaviors: slowing down when exceeding the skier's safe speed and braking before the end of the slope as well as a possibility of using accelerating force from ski poles. The study takes into account the whole system including ski routes and ski lifts.
The paper discusses selected issues related to the implementation and deployment of the Web Application Firewall that protects the target application by verifying the incoming requests and their ...parameters through matching them against recorded usage patterns. These patterns in turn are learned from the traffic generated by the users of the application. Since many web applications, including these operated by the government, are prone to exploits, there is a need to introduce new easily implementable methods of protection to prevent unauthorized access to sensitive data. A Learning Web Application Firewall offers a flexible, application-tailored, yet easy to deploy solution. There are certain concerns, however, regarding the classification of data that is used for the learning process which can, in certain cases, impair the firewall ability to classify traffic correctly. These concerns are discussed on the basis of reference implementation prepared by the authors.
System graficznego rozpoznawania ruchomych obiektów to rozwiązanie, które może być bardzo szeroko stosowane w życiu codziennym. Taki system powinien rozpoznać obiekty określone przez użytkownika ...przed jego uruchomieniem. Algorytmy stosowane w tym systemie powinny mieć dużą szybkość i dokładność. Istnieje wiele rozwiązań dla takich algorytmów, które wykorzystują wiele różnych technik i ustawień. W artykule przedstawiono podstawowe pojęcia i zasady systemu rozpoznawania obiektów mobilnych, a także przedstawiono koncepcję nowego systemu graficznego do rozpoznawania obiektów mobilnych, który ma większe możliwości niż systemy dotychczas używane.
W procesach zarządzania organizacjami gospodarczymi wymagane jest podejmowanie jak najlepszych decyzji, które pozwolą na zwiększenie konkurencyjności firmy oraz optymalizację jej działalności. ...Pomocne są w tym systemy informatyczne takie jak Business Intelligence. Jeszcze więcej można osiągnąć, gdy te systemy oparte są o technologie chmurowe. Artykuł przybliża tematykę systemów BI, technologii chmurowych oraz wskazuje różnice wydajnościowe między systemem opartym o serwer fizyczny, a środowiskiem usług analitycznych opartych o technologie chmurowe.
