The hierarchical hub location problem is encountered three-level network that is applied in production-distribution system, education system, emergency medical services, telecommunication network, etc. This paper addresses the hierarchical hub covering problem with single assignment accounting for mandatory dispersion of central hubs restriction as a special case. This formulation with incorpor...

Telecommunications are strategic assets for the design and operation of train control systems based on automatic train protection to prevent errors due to the human factor. The ERTMS/ETCS train control system developed in Europe is considered a world-wide de facto standard. It utilizes a dedicated telecommunication network based on the GSM-R system. This approach is not economically sustainable...

This paper presents possibility to use Telco 2.0 architecture interfaces to realize a service supporting public transport in agglomerations. Such systems are expected to be easily accessible for everyone and to be available in any location. Such expectations may only be met by a system using the latest achievements in the scope of telecommunication, which are API based on telecommunication oper...

This paper investigates the role of pitch accent information in spoken-word recognition in listeners in Fukushima, Japan, whose dialect is accentless. Previous research revealed that accentless listeners were less sensitive to pitch accent than Tokyo Japanese listeners. The present study asked whether middle-aged listeners’ use of accent information would differ from that of young listeners. 40...

The paper presents telemonitoring system for distant monitoring of physiological signs. The system is designed as modular system content input modules for monitoring various vital signs like ECG, NIBP and oxygen saturation, control module and telecommunication modules for streaming data using various wireless technologies like Bluetooth, GSM and WiFi.
