Opis:
The high degree of persons and property security risk, especially during cash value transport increases the demand for Cash/valuables-in-transit (CVIT) vehicles. These vehicles are, in addition to the transport of valuables, which include money, goods made of silver, gold, platinum, may also carry documents containing classified information important for the security of the State. It is noticeable tendency to increase safety requirements for use of these vehicles. The new Regulation of the Minister of Internal Affairs and Administration respecting “the requirements to be met to protect the monetary value stored and transported by businesses and other agencies” of 7 September 2010 (Dz.U. 2010.0166.1128) introduces three groups of CVIT vehicles: type A, type B and type C. The most strict, but also providing the highest levels of security are requirements for CVIT vehicles type A. This article refers to some problems concerning the design of these vehicles. The article presents regulations and standards referring to the CVIT vehicles obligatory in Poland. There are presented the uppermost technical requirements for new generation of CVIT vehicles. There are also proposed the attack protection performance classes and ratings for quality assessment of these vehicles, including the energy ratio. Some of the issues of construction and armour in relation to the use of the series cargo truck bodies and chassis for building the CVIT vehicles are discussed. There are discussed the operation and application of an innovatory auxiliary drive unit and some electronic systems

Opis:
Fast development of electronics in recent years causes that the number of various kind electronic systems is still growing. This causes also that requirements concerning tests of electromagnetic compatibility (EMC) of whole vehicles as well as their electric/electronic subassemblies become more significant. In this paper, the most important requirements of international regulations in the range of EMC, i. e., ECE UN Regulation No. l0 and EU Directive 2004/104/EC, have been outlined. Moreover, results of investigations of electric field strength inside of three chosen vehicles have been presented. The tests have been performed, according to Directive 2004/104/EC, in an absorber-lined shielded chamber in thefrequency band 20MHz to 2000MHz and at the electric field strength in the reference point equal to 30V/m. The most important results of these investigations have been presented in the form of graphs of electric field strength distribution in various points of tested vehicles. Individual electric/electronic devices o f a vehicle are exposed to electromagnetic field with a very wide range of values of electric field strength - depending upon a device position in a vehicle, vehicle type and antenna polarization. Values of electric field strength inside of a vehicle may essentially exceed the values recommended by standards for immunity tests of electric/electronic subassemblies.

Opis:
Szybki rozwój i wykorzystanie wielu źródeł mocy w zakresie małych i wielkich częstotliwości w przemyśle, telekomunikacji, nauce, technice i medycynie, wojsku, a nawet w gospodarstwie domowym spowodował rozwój narzędzi służących do pomiarów pola elektromagnetycznego (PEM) i związanej z tym metrologii pól elektromagnetycznych. W ochronie pracy i środowiska są to pomiary w bezpośrednim otoczeniu pierwotnych i wtórnych źródeł. Znaczną degradację dokładności pomiaru powodują specyficzne własności pola, w tym szczególnie pola bliskiego. Wymienione czynniki są źródłem wielu błędów zarówno na stanowiskach wzorców jak i bezpośrednio w trakcie pomiarów terenowych.
The development of contemporary civilization is associated with the consumption of more and more quantities of electromagnetic energy in communication, technology, science, medicine, and military in the household. The hazard created by an exposure to EMF requires the field measurements in the neighborhood of primary and secondary field sources. Remarkable degradation of the measurement accuracy is specific properties of the field, and in particular the near-field. The factors mentioned reduce the accuracy of the measurements both while the measurements are done with the use of standard field sets in a Lab and during the field measurements.

Opis:
The Lithuanian national standard of electric resistance is maintained as the basis for calibration and measurement capabilities published in the key comparison database of the International Bureau of Weights and Measures (BIPM). The stability and uncertainty of the resistance value measurements, performed since 2004 using the calibrated values of the standard resistors to predict their future behaviour as well as influence of environmental conditions, are discussed. Also discussed is the recovery of a standard resistor which had undergone a mechanical disturbance. It is concluded that the standard resistors operated by the Lithuanian National Electrical Standards Laboratory feature stable drift of resistance, which is well predicted by means of linear regression.

Opis:
To evaluate the occupational safety of a high signal operator exposed to the electric field induced by contact wires with a frequency of 50 Hz and a voltage of 27.5 kV, this study established a model of a high signal operator working in the vicinity of single and double-track railways. The electric field distribution in the operator’s body and his head were calculated and analyzed during the operation using the finite element method (FEM). The calculated results were compared with the international standard occupational exposure limits formulated by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and action levels (ALs), exposure limit values (ELVs) in Directive 2013/35/EU (EU Directive). In the case of a single-track railway exposure, the maximum electric field strength in the worker’s body, in the scalp layer, and inside the brain are 227 mV/m, 2.76 kV/m, and 0.14 mV/m, respectively. For a double-track railway exposure, the maximum internal electric field strength of the operator is 310 mV/m, which is 37.85% of the occupational exposure basic restriction limit. The maximum electric field strength in the head layers is 3.42 kV/m, which is 34.2% of the occupational exposure reference level and 34.2% of the low ALs. The maximum electric field strength of the brain is 0.19 mV/m, which is 0.19% of the occupational basic restriction limit and 0.135% of the sensory effects ELVs. Results show that the electric field exposure of the high signal operator to contact wires in single- and double-track railways is lower than the occupational exposure limits provided by the ICNIRP and EU Directive standards and is thus regarded as safe for workers.

Opis:
At the beginning of the work on the effects of global warming and climate change in the international area, there are efforts to reduce exhaust emissions. Because fossil fuel is depleting and exhaust emission gases emitted to the atmosphere are rising rapidly, energy efficiency is on the agenda in transportation. Therefore, automotive developers and scientists have undertaken new research in the automotive sector. Hybrid electric vehicle technology is one of the important studies that these researchers continue. In the hybrid electric vehicle technology, the hybrid engine is aimed to give the best results in terms of exhaust emission, fuel consumption and maintenance costs compared to other internal combustion engines, and at the same time the hybrid engine is aimed to perform better than other internal combustion engines. General information about the hybrid electric vehicle technology as one of the new and alternative technologies in these study is provided. In addition, information was given about exhaust emission, emission standards and fuel consumption. Comparisons were made between the hybrid engine and other internal combustion engines.

Opis:
Among the drivers influencing vehicular powertrain development, the field of vehicular exhaust emissions is experiencing wideranging and rapid changes. New emissions regulations such as Euro 6d and new test methods (RDE and WLTP) are the main challenges for the automotive industry caused by political, socioeconomic and technical factors. Air quality is very high on the political agenda and pressure remains to limit and reduce greenhouse gas emissions from the road transport sector. In addition to limits becoming increasingly stringent, the list of parameters subject to legal limits are slowly expanding – and, most importantly, these limits must be met under a wide range of conditions. A range of strategies are available to overcome these difficulties, which was explored during the 6th International Exhaust Emissions Symposium (IEES) hosted at BOSMAL in June 2018. This paper reports and summarises the topics of the 6th IEES and attempts a synthesis on the current status of the field of IC engines, hybrid powertrains and electric vehicles and what the coming years may hold for the automotive and fuel industries and other allied fields.
