ASTRI: Modelling of thermal energy storage systems for concentrated solar thermal

Concentrating Solar Thermal power often utilize Thermal Energy Storage (TES) systems to increase their value to the energy grid. New designs incorporate the latent heat of the storage media to increase the storage capability, and reduce the cost of the TES system. Understanding the thermodynamics of these systems is an important factor for the design, storage media and containment materials which form these systems. This project is aimed to develop a model for describing the thermodynamics of these complex systems, …

Place classification for mobile robots

For social robots and service robots to be able to operate effectively 'out of the box' in indoor environments, they must be able to understand the context of those environments without necessarily developing or having access to a complex map.The aim of this project is to develop a visual classifier for the type of rooms encountered in a typical home (bedroom, bathroom, kitchen, living room, laundry, etc.), medical facility (hallway, ward, waiting area, treatment room), commercial office environment (personal office, …

Culturomics of new extremophiles from Australia and their genomes

99% of the microbes that exist in any given environment have eluded culture under laboratory conditions. The 1% of microbes that have been cultured over the past 100 years are analogous to the unwanted weeds in a garden.However, a fraction of these 1% are very useful in commercial and industrial biotechnology, and impact our daily lives, for example in the manufacturing of alcohol, enzymes, food additives, antibiotics/antimicrobial agents, citric acid, amino acids, yoghurt, cheese and as molecular biology tools. …

Bioconversion (fermentation) of Syngas to useful bioproducts

Copious amounts of syngas (H2, CO and CO2 to a limited extent) is discharged in the air during petroleum refining, steel milling, and in the production of carbon black, coke, ammonia, and methanol. These green house gasses can be converted to useful products such as ethanol, butanol, acetic acid, butyric acid, and methane by microbial fermentation.Mesophilic acetogens which fix carbon dioxide using the Wood–Ljungdahl pathway, and include Clostridium carboxidivorans P7, Clostridium ljungdahlii, Clostridium autoethanogenum, Eurobacterium limosum, and Butyribacterium methylotrophicumare amongst …

Cloning of genes of industrially important thermostable enzymes from thermophilic bacteria isolated from the Great Artesain Basin of Australia

DNA polymerases used in the Polymerase Chain Reaction (PCR) are heat stable enzymes produced by extremophilic microbes and have a wide range of applications in molecular biology.Heat stable enzymes referred to as extremozymes also have potential applications in the food and chemical industries due to the much faster reaction rates of chemical / enzyme reactions at high as opposed to ambient or mesophilic temperatures. In other cases, there is a decrease in viscosity at high temperatures e.g starch, which renders …

Genus Caloramator, model thermoanaerobes for studies on speciation and biofilm development in the Great Artesian Basin ecosystem

The Great Artesian Basin (GAB) is the largest, multilayered, deep and naturally heated subsurface aquifer in the world (storage capacity of 1012m3) which provides the outback communities with an important water resource. The GAB has five stratified layers of different geological ages and in between these layers is the flowing aquifer waters. These aquifers are recharged along the Eastern Queensland Great Dividing Range from rain water percolation and flows underground at an average flow rate of 1 -2 m/yr until …

Finite element modelling of auxetic-fabric reinforced render under out-of-plane loading

Auxetic materials improve the behaviour of protective mortar renders by providing better bonding with the matrix and thereby eliminating the de-bonding and brittle failure.Negative Poisson’s ratio (NPR) of auxetic materials plays an important role in altering the failure pattern and decreasing the probability of delamination which is a common problem with other reinforcing materials.Our plot studies show encouraging data. Further investigation is, therefore, proposed through finite element modelling to validate the experimental results conducted on the out-of-plane behaviour of auxetic-fabric …

Development of impact resisting auxetic pad

Auxetic materials are being used in the fields of biomedical, sports and defence for protective applications. Their application in civil engineering is emerging particularly for impact resistance of structural members due to their unique negative Poisson’s ratio (NPR).This research is aimed at developing a 3D auxetic pad which exhibits NPR can provide better resistance against impact loads caused by, for example, derailed wheels impacting bridge deck, through high energy absorption.

Process querying

Process querying studies automated techniques for managing large collections of models of process-aware information systems based on process instances that these models describe. A user interacts with a collection of process models via process querying intents. A process querying intent is a formally specified request to manage a collection of process models for a particular purpose. Process querying research initiative spans a wide range of topics from theoretical studies of algorithms and the limits of computability of process querying techniques …

Process model repair

Process model repair refers to the following problem: Given an event log of a process-aware information system that does not fit to a process model, automatically transform the model such that the event log fits the transformed model better than it fits the original model.Thus, process model repair allows keeping models of process-aware information systems in sync with observed process instances by suggesting mechanisms for reflecting traces encountered in event logs in executions of the corresponding models. …

Visual understanding of doorways for mobile robots

For social robots and service robots to be able to operate effectively 'out of the box' in indoor environments, they must be able to understand the context of those environments without necessarily developing or having access to a complex map.The aim of this project is to develop a generic understanding of doorways for mobile robots relying only on visual information. We will be using the Pepper robot from Softbank Robotics as a test and demonstration platform. The aim is for …

Improving visual following for Pepper the social robot

For social robots and service robots to be able to operate effectively around people, they must be able to safely move around in environments where humans and other robots are also moving. Pepper, the social robot from Softbank Robotics is already capable of tracking and following a person, but can get confused if they move out of sight around a corner, or if there are multiple people moving in the robot’s field of view.The aim of this project is to …
