Stochastic patterns of inclusions during tissue growth

Biological tissue growth involves the secretion of new tissue (extracellular matrix, collagen fibers) by cells. This secretion incorporates scattered inclusions such as proteins and minerals into the new tissue. During bone tissue growth, some of the tissue-secreting cells themselves become incorporated into the new tissue. The distribution of these embedded cells is believed to influence subsequent tissue growth processes.

Autonomous underwater vehicle simulation in high-fidelity virtual environment

Game engines such as Unity and Unreal Engine provide realistic virtual environments to evaluate algorithms used within its coding.However, the simulation of hydrodynamic forces (or ocean currents) acting on a vehicle is not often considered in these evaluations.Furthermore, the vehicle dynamics that simulate thrust allocation is important for testing.

Thermal conductivity of carbon nanomaterials

Thermal management is one of the critical issues related with advanced electronics. To ensure the operation, it is important for the heat removal or isolation. Due their high thermal conductivity, carbon nanomaterials have played a unique role in thermal management area.

Verification of a new discrete-event simulation C++ library

QUT has developed a new discrete-event simulation (DES) library in C++ called SLCPP, a highly computationally efficient DES engine intended for stochastic optimization where computational efficiency is critical.This project aims to implement several DES models (queuing networks, basic supply chain, etc) within SLCPP, with the same models to be mirrored within a commercial package (ExtendSim or AnyLogic for example).Results obtained using SLCPP and the commercial package should be compared and reconciled to identify any potential improvements to SLCPP and ultimately …

Predicting universtiy class-sizes with monte-carlo simulation

Accurately predicting the number of students likely to enrol in particular units is important for universities to construct timetables and determine workload allocations for academic staff.By the time that student numbers are confirmed for a unit, timetabling has been close to finalised and workload allocations already determined. Therefore, mismatch between predicted and allocated unit enrolments leads to sub-optimal timetabling and workload allocation.This project aims to develop and evaluate a methodology to provide some analytical rigor to a process that has …

Stochastic modelling in the life sciences

There are many areas in biology and physiology where stochasticity has proven to be beneficial. For example, biological cells are now known to exploit stochasticity in order to avoid cell death.Research in this area has four components:the development of stochastic models to capture important attributes of biological processesthe development of efficient multi-scale stochastic simulation techniquesparameter-fitting of the models against experimental data using populations of models and Bayesian techniquessophisticated parallel implementations and visualisation of multidimensional data sets. …

Dynamical systems and theoretical biology

Numerous physical and biological systems involve processes of diffusive and/or advective transport (for example, pollutant dispersal, insect pest infestation, heat) and/or reaction (such as interaction, growth, decay) that vary over space and time. As such they can best be described by coupled systems of partial differential equations.Projects are available that focus on aspects of constructing and validating mathematical models and simulations of tissue growth and repair problems, such as epidermal and corneal wound healing, bone fracture healing and tumour growth.Mathematically, …

Simulating the mechanical properties of PCL scaffolds produced by melt electrowriting (MEW) technique for rotator cuff repair

The treatment of rotator cuff (shoulder) repair is sub-optimal with up to 50% failure rate in the first year. This situation is very alarming. One cause of implant failure is its poor mechanical strength as the rotator cuff is loaded under static as well as dynamic conditions.Fatigue testing of scaffold structures is costly and time consuming process. Other factors such as relative density, cell topology, and struts' geometry also effect the fatigue behaviours of materials. Hence, the study of these …

Impact of on-street and off-street parking on traffic congestion in high-density urban areas

One of the potential benefits of parking reforms is the reduction of congestion in city streets due to the reduction of circulation caused by motorists searching for parking. However, there is minimal evidence in Australia and around the world to support this hypothesis.This project aims to improve the body of knowledge on congestion caused by circulation looking for parking within high-density urban areas.Data from driver surveys, traffic sensors and parking transactions will be used to determine the percentage of vehicles …

Modelling and simulation of industrial processes and products

Industrial processes and products can be described as 'multi-problems' in that they are often multi-scale, multi-phase and multi-component in nature. The analysis of such problems sits in the exciting nexus of applied mathematics, physical science and engineering science.
