The Office of Safety of the Federal Railroad Administration (FRA) is responsible for ensuring public and personnel safety in U.S. railroad operations. This office ensures the safe rail transportation of hazardous materials by conducting inspections of railroad operations and equipment, including tank cars, and developing safety-related regulations. In the past few years, the Office of Safety has been using risk analysis as a tool in making rational regulatory decisions on hazardous materials transportation in tank cars. A risk analysis protocol developed by FRA is described to evaluate the risks to the U.S. population arising from the transportation of different types of chemicals in tank cars on the U.S. railroad system. Following several recommendations of the National Transportation Safety Board requiring the shipment of several hazardous chemicals in highly protected, pressure-rated tank cars rather than in the minimum packaging authorized by the Code of Federal Regulations, a risk-based evaluation was made on the effect of implementing these recommendations on the overall risk reduction. The risk results were presented in the parameters of Military Standard 882-B. Policy decisions were made based on the results.

Connected objects are deployed all over the world. Thus, they are contributing to improving communications. In urban areas, technological challenges are gradually being overcome, and advances in this area are exponential. Unfortunately, isolated territories such as northern Quebec do not beneficiate from this technological progress. Yet, northern Quebec relies on abundant natural resources, with notably its huge hydroelectric dams and iron mines, and therefore, the region’s economic life revolves essentially around the exploitation of these resources and is heavily reliant on rail transportation. However, according to Transport Canada, 1246 railroad accidents were reported in 2019 to the Transportation Safety Board (TSB). Thirty-eight people described as trespassers lost their lives, and five railroad employees were fatally injured. In this context, we present the implementation of a security system in an isolated environment for employees intervening on the railroad track to warn them of the imminent arrival of a train. Due to the context of the isolated environment, i.e., without an electrical network, without internet, and without an LTE network, a solution for employees has been developed using a Zigbee telecommunication system and a connected watch. A case study on a train operating in a remote and isolated area in northern Quebec is presented to validate the performance of the proposed system based on an open-source and customizable solution.

The book provides an introduction to Kantian constitutional theory and the European system of rights protection. Part I sets out Kant’s blueprint for achieving Perpetual Peace and constitutional justice within and beyond the nation state. Part II applies these ideas to explain the gradual constitutionalization of a Cosmopolitan Legal Order: a transnational legal system in which justiciable rights are held by individuals; where public officials bear the obligation to fulfil the fundamental rights of all who come within the scope of their jurisdiction; and where domestic and transnational judges supervise how officials act. The authors then describe and assess the European Court’s progressivie approach to both the absolute and qualified rights. Today, the Court is the most active and important rights-protecting court in the world, its jurisprudence a catalyst for the construction of a cosmopolitan constitution in Europe and beyond.

This paper presents a method of utilizing a non-contact position sensor for the tilting and movement control of a rotor in a rotary magnetic levitation motor system. This system has been studied with the aim of having a relatively simple and highly clean alternative application compared to the spin coater used in the photoresist coating process in the semiconductor wafer process. To eliminate system wear and dust problems, a shaft-and-bearing-free magnetic levitation motor system was designed and a minimal non-contact position sensor was placed. An algorithm capable of preventing derailment and precise movement control by applying only control without additional mechanical devices to this magnetic levitation system was proposed. The proposed algorithm was verified through simulations and experiments, and the validity of the algorithm was verified by deriving a precision control result suitable for the movement control command in units of 0.1 mm at 50 rpm rotation drive.

With the continuous development of the mining industry, the world’s major mines have gradually entered the intelligent stage. In intelligent underground mines, the operation roads of the underground transportation equipment are very complicated, and the monitoring and control of the underground traffic have become the problems to be solved in the intelligent underground mines. Therefore, on the basis of solving the practical problems of underground mines, the concept paper discusses the possibility of the communication-based train control (CBTC) system being applied to underground mines through the summary and induction of the related literature. As mining engineers, we have proposed the function design for the CBTC system to solve the problems in underground mine rail transportation, but we still need to continue to work hard for the future development of the underground mines. The concept paper serves as a guide to the Tossing out a brick to get a jade gem, and it has implications for the development and the future of underground mine transportation.
