Temporal synchronization of emulated and simulated models for assessment of networked systems
… can be greatly simplified by constructing co-simulated models of the system where cost-effective simulations of a physical environment and the underlying network are temporally integrated with high fidelity emulations of the core application logic. In a co-simulation, certain components of the …

Budget Analysis of Spring, Fall with Winter Clean-up, and High-Fertility Fall Lambing Systems in a Simulated Fixed Forage Resource
A successful business needs to generate enough cash to cover expenses, current debt, and family living expenses, pay interest on owned and borrowed capital, maintain productivity, and earn a reasonable return for the operator. Income from sheep production is generally only part of a total farm and …

A study into concurrent advancement of simulation and emulation using composite synchronization.
… into the real world. However, behavior of purely simulated models is limited by the functionality of the network simulator. Instead, emulation can be combined with simulation to simulate real traffic generated by real applications. This integration of simulation and emulation is done in virtual …

Residual Model Learning for Microrobot Control
… on microrobots and large errors between simulated models and real robots make current model-based learning and sim-to-real transfer methods difficult to apply. We propose a novel framework residual model learning (RML) that leverages approximate models to substantially reduce the sample …

Optimal Control of the Cheetah During Rapid Manoeuvres
… slow. The lack of data means that there are no simulated models of cheetahs known to be representative of dynamic movements such as acceleration and turning. In this project, a modelling change is investigated that decreases the time to find trajectories for models involving long serial chains …

Controlled virtual time advancement in conjoined emulation and network simulation
… of network services are more accurate than simulated models. However this is achieved at an increased computational cost. Combining emulation with simulation allows more accurate, controllable and repeatable evaluation of applications but such hybrid systems are generally not scalable. …
