Constant bandwidth servers with constrained deadlines [PDF]
Proceedings of the 25th International Conference on Real-Time Networks and Systems, 2017 The Hard Constant Bandwidth Server (H-CBS) is a reservation-based scheduling algorithm often used to mix hard and soft real-time tasks on the same system.

Constant bandwidth server revisited [PDF]
ACM SIGBED Review, 2015 The Constant Bandwidth Server (CBS) is an algorithm for providing temporal protection and real-time guarantees to real-time sporadic tasks. Recently, an implementation of this algorithim called SCHED_DEADLINE has been included in the Linux kernel. Therefore, the CBS algorithm is now used to serve more generic tasks than do not obey to the classical ...

Tunable lumped-element bandpass filters with constant bandwidth
Известия высших учебных заведений России: Радиоэлектроника, 2015 Lumped-element bandpass filters using LC-tanks and immittance inverters are considered. Tuning of the central frequency is provided by using variable capacitors of LC-tanks and immittance inverters.

Design of Tunable Coaxial Bandpass Filter Based on Embedded Stepped Impedance Resonators
IEEE Access, 2023 This paper describes a method for designing tunable coaxial bandpass filters based on an inserted coaxial stepped impedance resonator (SIR). The miniaturization of the coaxial resonator is realized by the shape of the stepped impedance structure.

Migrating Constant Bandwidth Servers on Multi-Cores [PDF]
29th International Conference on Real-Time Networks and Systems, 2021 This paper introduces a novel admission test for partitioned CBS reservations on multi-core systems, that, on a new reservation arrival, is capable of exploiting better the CPU capacity in cases in which tasks have just recently left the CPU (for example, due to termination or migration to a different CPU).
