A Two-Server Queue with Interdependence between Arrival and Service Processes
Mathematics, 2023 In this paper, we analyse a queueing system with two servers where the arrival and service processes are interdependent. The evolution of these processes is governed by transitions on the product space of three Markov chains, which are descriptors of the

Do Sojourn Effects on Personality Trait Changes Last? A Five‐Year Longitudinal Study
European Journal of Personality, EarlyView., 2020 Abstract This study examined sojourners' long‐term personality trait changes over five years, extending previous research on immediate sojourn effects. A sample of German students (N = 1095) was surveyed thrice (T1–T3) over the course of an academic year.

BMC Medical Informatics and Decision Making, 2022 Background Microsimulation models are mathematical models that simulate event histories for individual members of a population. They are useful for policy decisions because they simulate a large number of individuals from an idealized population, with ...

On the Optimal Input Rate in Queues with Batch Service
Axioms, 2023 In recent years, queuing systems with batch service are emerging as powerful and flexible mathematical models in different frameworks. In this paper, we consider a single server queuing system with Poissonian arrivals, infinite buffers, and a constant ...

Optimal Service Rate in Cognitive Radio Networks With Different Queue Length Information
IEEE Access, 2018 Cognitive radio (CR) technology effectively overcomes spectrum inefficiency by providing the capability that unlicensed users can share the radio frequency spectrum with licensed users. In this paper, we consider a CR system with heterogeneous users.

The Delay Time Profile of Multistage Networks with Synchronization
Mathematics, 2023 The interaction between projects and servers has grown significantly in complexity; thus, applying parallel calculations increases dramatically. However, it should not be ignored that parallel processing gives rise to synchronization constraints and ...

Symptom lead time distribution in lung cancer:natural history and prospects for early diagnosis [PDF]
, 2014 BACKGROUND: Before their diagnosis, patients with cancer present in primary care more frequently than do matched controls. This has raised hopes that earlier investigation in primary care could lead to earlier stage at diagnosis.METHODS: We re-analysed ...
