2. Babka gymnotrachelus (Kessler, 1857), Racer Goby Gobius gymnotrachelus Kessler, 1857: 464; type locality: Dniester River and its tributaries, especially River Slutsch; syntypes: ZIN 2105 (1, lost). Etymology: Greek, gymnus = naked + Greek, trachelos = neck, refers to the limited predorsal squamation. Distribution and habitat: Black Sea, Sea of Azov,

IEEE Communications Magazine, 1992
A compromise reached at the 1992 World Administrative Radio Conference (WARC-92) concerning the international frequency allocations for personal communications systems (PCSs) is reviewed. The PCS debate at the WARC-92 resulted in the collision of two nearly polar views: that of the Europeans, whose advocacy of PCS techniques was limitless; and that of ...

Study on the adsorption properties of metal–organic frameworks (PCN-228’, PCN-230)
Materials Technology, 2020The adsorption properties of two kinds of metal–organic frameworks (MOFs), PCN-228ʹ and PCN-230, have been studied by the grand canonical Monte Carlo (GCMC) method for the absorption of N2, H2, CH4...

Polychlorinated Naphthalenes (PCNs)
2000Polychlorinated naphthalenes (PCNs) have been commercially produced and used mainly in electrical devices, but also for impregnation of wood, paper and textiles to attain waterproofness, flame resistance and protection against insects, molds and fungi. Today, the PCNs are widespread in the environment and are to be regarded as an environmental problem.

Adaptive channel allocation for wireless PCN
Mobile Networks and Applications, 1999In cellular networks, forced call terminations due to handoff call blocking are generally more objectionable than new call blocking. In order to maintain an acceptable call dropping probability rate, we propose, in this paper, two new guard channel schemes: an adaptive one – New Adaptive Channel Reservation (NACR) – and a dynamic one – Predictive ...

Protected Core Networking (PCN): PCN QoS and SLA definition
2013The aim of this paper is to share the early results available from IST-103 regarding QoS (Quality of Service) and SLA (Service Level Agreement) definition. This paper is a position paper addressing how PCN WG sees Quality of Service Management & Service Level Agreement Management.

PCN: son of cellular? The challenges of providing PCN service
IEEE Communications Magazine, 1991The engineering and marketing problems posed by personal communications networks (PCNs) are examined. The characteristics common to all PCNs are identified, emphasizing their use of small-coverage cells (microcells). Trials undertaken by the Bell Atlantic telephone companies are discussed. >

IEE Colloquium on Roaming with Data, 1995
Personal communication networks (PCNs) are already operating in the UK and a few other countries, and new PCNs are planned for commencement of service during the next two or three years in several countries around the world. These networks operate according to the DCS-1800 standard developed by ETSI members.

IEEE Communications Magazine, 1992
The interference levels that may be expected for a range of conventional cellular and microcellular clusters used in personal communication networks (PCNs) and personal communication systems (PCSs) are discussed. Simulation results show that for conventional size cells, 32- and 64-level quadrature amplitude modulation (QAM) schemes are preferred for ...
