Occurrence and transition probabilities of omega and high-over-low blocking in the Euro-Atlantic region [PDF]
Weather and Climate Dynamics, 2021 Stationary, long-lasting blocked weather patterns can lead to extreme conditions such as anomalously high temperatures or heavy rainfall. The exact locations of such extremes depend on the location of the vortices that form the block.

Call Blocking Probabilities under a Probabilistic Bandwidth Reservation Policy in Mobile Hotspots
Telecom, 2021 In this paper we study a mobility-aware call admission control algorithm in a mobile hotspot. To this end, a vehicle is considered which has an access point with a fixed capacity. The vehicle alternates between stop and moving phases. When the vehicle is

Performance Evaluation of Two-Link Multirate Loss Models with Restricted Accessibility
Journal of Telecommunications and Information Technology, 2020 We consider a two-link communication system with restricted accessibility that services Poisson arriving calls of many service-classes and propose a multirate teletraffic loss model for its analysis.

Probabilistic Retry and Threshold Multirate Loss Models for Impatient Calls
Telecom, 2021 In this paper, a link of fixed capacity is considered that services calls from different service-classes. Calls arrive in the link according to a Poisson process, have an initial (peak) bandwidth requirement while their service time is exponentially ...

Traffic-Based Heuristics for Regenerator Placement in Translucent Dynamic Optical Networks
Applied Sciences, 2022 We propose in this paper two heuristic strategies to solve the regenerator placement problem (RPP) in translucent networks under dynamic traffic. The heuristics are based on both the forecast of the offered load and estimates of blocking probabilities in
