Multi-Server Secure Aggregation with Unreliable Communication Links

open access: yesGLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023
In many distributed learning setups such as federated learning (FL), client nodes at the edge use individually collected data to compute local gradients and send them to a central master server. The master server then aggregates the received gradients and broadcasts the aggregation to all clients, with which the clients can update the global model.

Multi-server queueing system with reserve servers

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In this paper, we investigate a multi-server queueing system with an unlimited buffer, which can be used in the design of energy consumption schemes and as a mathematical model of unreliable real stochastic systems.

Joint Deployment Optimization of Parallelized SFCs and BVNFs in Multi-Access Edge Computing

open access: yesApplied Sciences, 2023
In multi-access edge computing (MEC) networks, parallelized service function chains (P-SFCs) can provide low-delay network services for mobile users by deploying virtualized network functions (VNFs) to process user requests in parallel.

Efficient memory management in VOD disk array servers usingPer-Storage-Device buffering [PDF]

open access: yes, 1998
We present a buffering technique that reduces video-on-demand server memory requirements in more than one order of magnitude. This technique, Per-Storage-Device Buffering (PSDB), is based on the allocation of a fixed number of buffers per storage device,

How reproducible and reliable is geophysical research?

open access: yesSeismica, 2023
Geophysical research frequently makes use of agreed-upon methodologies, formally published software, and bespoke code to process and analyse data. The reliability and repeatability of these methods is vital in maintaining the integrity of research ...
