Using gaming technologies to embed this approach in a three-dimensional (3D) simulation environment provides users with a dynamic, responsive, visually engaging, and cost effective learning experience. Representing real world problems in 3D simulation environments develops knowledge and skills that are applicable to their resolution.

The Simulation, User, and Problem-based Learning (SUPL) Design Framework was developed to inform the design of learning environments which develop problem-solving knowledge for real world application. This framework identifies design factors relative to the user, the problem-solving task, and the 3D …

Swamp : Walking The Wetlands Of The Swan Coastal Plain ; And With The Exegesis, A Walk In The Anthropocene: Homesickness And The Walker-Writer, Anandashila Saraswati

Theses: Doctorates and Masters

This project is comprised of a creative work and accompanying exegesis. The creative work is a collection of poetry which examines the history and ecology of the wetlands and river systems of the Swan Coastal Plain, and which utilises the practice of walking as a research methodology. For the creative practitioner walking reintroduces the body as a fundamental definer of experience, placing the investigation centrally in the corporeal self, using the physical senses as investigative tools of enquiry. As Rebecca Solnit comments in her history of walking, ‘exploring the world is one of the best ways of exploring the mind, …

Development Of A Modular Dual Engine Hybrid Electric Vehicle Simulation Model, Kenan Baltaci

Dissertations and Theses @ UNI

Depleting resources of fossil fuel, climate change impacts, high oil prices, and strict emission requirements are leading to the research on efficient, environmentally friendly, and lowered fossil fuel dependent solutions in the transportation field. While a number of studies used computer modeling and simulation tools to investigate hybrid electric vehicles (HEVs), very few attempted to model and simulate a dual-engine hybrid vehicle. Designing a vehicle engine to meet energy needs in the fully loaded condition is not an optimal solution for manufacturers and customers. The larger the engine, the higher the manufacturing costs for companies, and higher fuel consumption for …
