This chapter provides basic knowledge on the principles used in modern signalling systems to ensure safe train separation and to establish safe routes through point zones. For train control, lineside signals are compared with cab signalling. For block protection, fixed block and moving block...

This paper addresses the need for reliable action guidelines that can be used by organisations in turbulent environments. Building on current conceptual and empirical research, we suggest an analytical approach for the management of surprising and potentially damaging events. In order to do so...

This paper presents a new method of noise-immune data transmission of BPSK signals using randomization. Proposed model was and implemented in software. The method can be used for digital data exchange in conditions of strong interference, in particular, in the computer telecommunication systems,...
