Robust Phase Behavior of Model Transient Networks

Transient Behavior of Queueing Networks

We present algorithms for approximating time-varying performance parameters for a Gt/G/c queuing system and for networks of such stations. The key ingredient is a formula for computing approximate sojourn time distributions for a Gt/G/c queuing system with time-varying arrivals and phase-type service times. The formula is based on transient Little laws expressing expected queue lengths and outp...

Transient behavior of a population dynamical model

The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with the environment. We investigate different asymptotic dynamical regimes and the role of the external noise on the probability distribution of the local field. Population dynamics attracted a lot of attention in recent...

Application of Homotopy Perturbation Method to One-dimensional Transient Single-phase EM Heating Model

Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...
