Evaluation of the current technologies used for the physical security and safety of selected railway tunnel portals as a case study in the Czech Republic
(Springer Nature, 2024) Smažinka, Dalibor; Kavan, Štěpán; Hrinko, Martin
The security and safety of the railway tunnels require technical measures, information processes, and trained experts. Proper implementation and integration of these elements is crucial to protect lives, property, and the operation of the rail network. The purpose of this study is to identify and describe technological security and safety measures at the portals of selected railway tunnels greater than 1000 m in the conditions of the Czech Republic and their subsequent evaluation. The method of semi-structured interviews with experts with experience in the implementation of security and safety measures was used for the elaboration. SWOT analysis was used to assess the safety level of selected railway tunnels. The evaluation was carried out based on multi-criteria decision making and pairwise evaluation on the principle of Fuller's triangle. The technical solutions of two currently known technological solutions in the case study for accident elimination based on lidar detection supplemented by cameras are characterized by fundamental differences. The solution in the Ejpovice tunnel focuses on the detection of objects in the immediate vicinity of the portal or already entered it. The solution in the BrezenskATIN SMALL LETTER Y WITH ACUTE tunnel focuses on a larger detection zone extending tens of meters in front of the tunnel portal and is divided into two parts with different logic, the pre-alarm and the alarm itself. Integration of individual elements into a proactive and automated system that uses modern AI-based analytical algorithms and respects the process and technology specifics of the railway environment is important for the safety and security of the railway tunnel.
A review of thermal exposure and fire spread mechanisms in large outdoor fires and the built environment
(Elsevier, 2023) Filkov, Alexander I.; Tihay-Felicelli, Virginie; Masoudvaziri, Nima; Rush, David; Valencia, Andres; Wang, Yu; Blunck, David L.; Valero, Mario Miguel; Kempná, Kamila; Smolka, Jan; De Beer, Jacques; Campbell-Lochrie, Zakary; Centeno, Felipe Roman; Ibrahim, Muhammad Asim; Lemmertz, Calisa Katiuscia; Tam, Wai Cheong
Due to socio-economic and climatic changes around the world, large outdoor fires in the built environment have become one of the global issues that threaten billions of people. The devastating effects of them are indicative of weaknesses in existing building codes and standard testing methodologies. This is due in part to our limited understanding of large outdoor fire exposures, including the ones from wildland to communities and within communities. To address this problem, the Ignition Resistance Committee (IRC) of the International Association of the Fire Safety Science working group ‘Large Outdoor Fires and the Built Environment’ was established. This manuscript is the result of one of the IRC's initiatives to review current knowledge on exposures associated with large outdoor fires, identify existing knowledge gaps, and provide recommendations for future research. The article consists of two sections: the wildland fire exposure to the built environment and the settlement fire exposure to structures. Each section presents a comprehensive review of experimental and numerical studies of exposure mechanisms (flame contact and convection, radiation, and firebrands). The review concludes with a discussion on data consistency and existing knowledge gaps to highlight future directions for each of the three fire exposure mechanisms.
Trends in SARS-CoV-2 cycle threshold values in the Czech Republic from April 2020 to April 2022
(Springer Nature, 2023) Mušálková, Dita; Piherová, Lenka; Kwaśný, Ondřej; Dindová, Zuzana; Stančík, Lubor; Hartmannová, Hana; Sláma, Otomar; Pecková, Petra; Pargač, Josef; Minárik, Gabriel; Zima, Tomáš; Bleyer, Anthony J.; Radina, Martin; Pohludka, Michal; Kmoch, Stanislav
The inability to predict the evolution of the COVID-19 epidemic hampered abilities to respond to the crisis effectively. The cycle threshold (Ct) from the standard SARS-CoV-2 quantitative reverse transcription-PCR (RT-qPCR) clinical assay is inversely proportional to the amount of SARS-CoV-2 RNA in the sample. We were interested to see if population Ct values could predict future increases in COVID-19 cases as well as subgroups that would be more likely to be affected. This information would have been extremely helpful early in the COVID-19 epidemic. We therefore conducted a retrospective analysis of demographic data and Ct values from 2,076,887 nasopharyngeal swab RT-qPCR tests that were performed at a single diagnostic laboratory in the Czech Republic from April 2020 to April 2022 and from 221,671 tests that were performed as a part of a mandatory school surveillance testing program from March 2021 to March 2022. We found that Ct values could be helpful predictive tools in the real-time management of viral epidemics. First, early measurement of Ct values would have indicated the low viral load in children, equivalent viral load in males and females, and higher viral load in older individuals. Second, rising or falling median Ct values and differences in Ct distribution indicated changes in the transmission in the population. Third, monitoring Ct values and positivity rates would have provided early evidence as to whether prevention measures are effective. Health system authorities should thus consider collecting weekly median Ct values of positively tested samples from major diagnostic laboratories for regional epidemic surveillance.
Hazardous substances and their effects on drinking water sources
(Polskie Towarzystwo Przeróbki Kopalin, 2021) Kročová, Šárka
Drinking water cannot be produced from every raw surface or groundwater in the European Union countries. The source must meet the set criteria for the raw water quaility. At present time, drinking water sources meet these requirements. However in the climate change period, accompanied in particular by long-term loss of water volumes, the set limit values for individual categories of raw water may be frequently exceeded. Human society must be prepared for this threat and take legislative and technical-operational steps in a timely manner to eliminate the risk This paper deals with the issue in the basic scope and declares what producers and steps can be used in practice to increase the resilience of water resources to the expected change in the water quality.
Identifying critical elements of road infrastructure using cascading impact assessment
(Vilnius Gediminas Technical University, 2020) Řehák, David; Patrman, David; Brabcová, Veronika; Dvořák, Zdeněk
Road transport is a key means of transporting people and cargo on land. Its particular advantages are speed and operability, which are balanced, however, by dependence on road infrastructure. Road infrastructure reliability is an important factor in its functioning. If some elements of road infrastructure are disrupted or fail, the function of dependent infrastructures, such as the integrated rescue system or industry, are also impaired and may fail. These important elements of road infrastructure should be identified as critical and be given greater attention when identifying weaknesses and implementing subsequent security measures. This article introduces the Identifying Critical Elements of Road Infrastructure (ICERI) method, which was designed to make use of Cascading Impact Assessments (CIA). The use of CIA allows critical elements to be identified through impact escalation analysis. These impacts can therefore be monitored not only in road transport infrastructure but also across the entire critical infrastructure system.
