In everyday life, this is most evident in passenger cars, but at the same time, there are huge advances in freight transport and aviation. In order to maintain this developing trend, developers are striving to achieve the highest possible power density and maximum efficiency. With this increased efficiency comes longer driving range, thus electric car industry could take a bigger slice of the urban commuter traffic. 2021-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/25725 Some comments on the oedometric relaxation test Imre, Emőke Hydraulic fracturing occurs on the condition that the tensile strength of the particle contacts is equal to the absolute value of the negative effective stress. The measurement of the tensile strength of the particle contact is not easy. This paper discusses the Multistage Oedometric Relaxation Test (MRT). Analysis of test results shows that MRT can be a candidate test for the aforementioned measurement 2024-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/25720 5G technology and its impacts towards road safety and Autonomous Cars Lukács, Judit; Douzi, Ahmed 5G C-V2X (cellular vehicle to everything) will be the communication standard between vehicles, infrastructures such as traffic lights, intersections, cameras, or even the various sensors along roads and highways and other road users such as cyclists and pedestrians. The usage 5G cellular can help us avoid accidents on routes. The vehicle can send signals to other vehicles if something suddenly happens. 5G will have to be accompanied by all the proper technical solutions to frame the information and send it as quickly as possible. On the other hand, autonomous vehicles are the new generation of smart vehicles with the ability to self-driving by using various electronic devices and informatics methods. Autonomous cars rely on information and connection technologies based on a very efficient network. An intelligent driving system is one of many AV (Autonomous vehicles) features that can be realized via 5G technology by applying an intelligent transporting system. This paper aims to chew over the impact and intimation of 5G on AV from several dimensions and present an overview of IoT’s role in our lives and how 5G will be affected in AV. In addition, 5G for AV is 2024-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/24965 The Role of Operating and Financial Leveragein Exports and Technological Development János Löblin 2018-01-01T00:00:00Z
