Towards parameter-less 3D mesh segmentation

This thesis focuses on the 3D mesh segmentation process. The research demonstrated how the process can be done in a parameterless approach which allows full automation with accurate results. Applications of this research include, but not limited to, 3D search engines, 3D character animation, robotics environment recognition, and augmented reality.

Bird flock

The work consists of a set of six, utilitarian wine glasses. Each glass features the engraving of a bird silhouette; the six engravings represent a flock of birds and also six key-poses in the animated flight-cycle of one bird. Beside the array of wine glasses sits a screen on which is displayed a looped animation of this same bird in flight. In a way, the six wine glasses represent the six animation cels of the displayed animation. Additionally, each engraved glass serves as a sight-trigger for a smart-phone or other mobile device. If one has the Aurasma app on their device and holds it up to ‘look at’ any one of the engravings, the animation of the flying bird will also be displayed on their device’s screen.

Dynamic virtual workspace for teleoperation of heterogeneous robots in non-deterministic environments

Robots are ever increasing in a variety of different workplaces providing an array of benefits such alternative solutions to traditional human labor. While developing fully autonomous robots is the ultimate goal in many robotic applications the reality is that there still exist many situationswere robots require some level of teleoperation in order to achieve assigned goals especially when deployed in non-deterministic environments. For instance teleoperation is commonly used in areas such as search and rescue, bomb disposal and exploration of inaccessible or harsh terrain. This is due to a range of factors such as the lack of ability for robots to quickly and reliably navigate unknown environments or provide high-level decision making especially intime critical tasks. To provide an adequate solution for such situations human-in-the-loop control is required. When developing human-in-the-loop control it is important to take advantage of the complimentary skill-sets that both humans and robots share. For example robots can performrapid calculations, provide accurate measurements through hardware such as sensors and store large amounts of data while humans provide experience, intuition, risk management and complex decision making capabilities. Shared autonomy is the concept of building robotic systems that take advantage of these complementary skills-sets to provide a robust an efficient robotic solution. While the requirement of human-in-the-loop control exists Human Machine Interaction (HMI) remains an important research topic especially the area of User Interface (UI) design.In order to provide operators with an effective teleoperation system it is important that the interface is intuitive and dynamic while also achieving a high level of immersion. Recent advancements in virtual and augmented reality hardware is giving rise to innovative HMI systems. Interactive hardware such as Microsoft Kinect, leap motion, Oculus Rift, Samsung Gear VR and even CAVE Automatic Virtual Environments [1] are providing vast improvements over traditional user interface designs such as the experimental web browser JanusVR [2]. This combined with the introduction of standardized robot frameworks such as ROS and Webots [3] that now support a large number of different robots provides an opportunity to develop a universal UI for teleoperation control to improve operator efficiency while reducing teleoperation training.This research introduces the concept of a dynamic virtual workspace for teleoperation of heterogeneous robots in non-deterministic environments that require human-in-the-loop control. The system first identifies the connected robots through the use kinematic information then determines its network capabilities such as latency and bandwidth. Given the robot type and network capabilities the system can then provide the operator with available teleoperation modes such as pick and place control or waypoint navigation while also allowing them to manipulate the virtual workspace layout to provide information from onboard camera’s or sensors.

Trace memory: after decay

In this exhibition, interdisciplinary artist Tonya A. Meyrick presents a body of new work that explores the relationship between memory and place.Tonya A. Meyrick explores the recollection and perception of memory and considers how our memories are not stable; rather, they are fickle and tied to the places which we inhabit, past events and the ebb and flow of our daily patterns. The act of remembering, putting our memories back together is the thread that runs through this exhibition of large format digital still and moving artworks coupled with an experience of augmented reality

Immersive interfaces for art education teaching and learning in mixed reality virtual and real world environments

Selected ubiquitous technologies encourage collaborative participation between higher education students and educators within a virtual socially networked e-learning landscape. Multiple modes of teaching and learning, ranging from real world experiences, to text and digital images accessed within the Deakin Studies Online learning management system and a constructed virtual world in which the user’s creative imagination transports them to the “other side” of their computer screens is discussed in this paper. These constructed environments support interaction between communities of learners and enable multiple simultaneous participants to access graphically built 3D environments, interact with digital artifacts and various functional tools and represent themselves through avatars, to communicate with other participants and engage in collaborative art learning. A narrative interpretative research approach was used to profile the 21st century higher education student learner, to investigate the lived experience and multiple art learning perspectives documented in student visual journal entries and art educator observations to ascertain if an e-technology rich augmented learning environment resulted in the establishment of more effective e-learning communities of practice.

`Modern` learning methods : rhetoric and reality - further to Sadler-Smith et al

Working in the UK, Sadler-Smith, Down and Lean, in their article “‘Modern’ learning methods: rhetoric and reality”, Personnel Review, Vol. 29 No. 4, 2000, pp. 474-90, have shown that distance learning methods are neither favoured nor perceived as effective by enterprises pursuing training that yields a competitive edge. They have suggested that these methods need to be integrated with other more conventional on-job training methods. This paper, based on Australian research, shows a tension between the requirements of flexible training methods based on distance learning methods, and the characteristics that typify learners and their workplaces. That identified tension is used to suggest how an integration of training methods may be effected in workplaces.

Assets in Accounting: Reality Lost

The aim of this paper is to trace changes in the definitional concept of assets in an attempt to discover why professional accounting bodies in the major English speaking countries have adopted the problematic abstract 'future benefit' notion, which is so far removed from the simple concept of assets as exchangeable things or rights. It is suggested that in the future financial reporting requirements for business entities include a statement of 'separably exchangeable property' and legal obligations at the reporting date.

Reality therapy and the human energy field : working with needs that influence mind and body

There is accumulating evidence that body and mind, or rather the physical and the non-physical, are intrinsically connected. The mechanisms through which reality therapy works on mind and body may be explained via positive dynamics in the central nervous system, the body's biochemistry and the human energy field. The purpose of this paper is to show the relationship between choice theory and the nature of the power centers in the human energy field. Understanding the drivers behind human behavior and facilitating the choice to think realistically and to make responsible choices assists wholeness and enhances the physical, mental and spiritual health.

Human right to food security in refugee setting: rhetoric versus reality

Despite recent advances in the area of humanitarian responses and the publication and dissemination of various guidelines with regard to nutritional interventions, there is, however a paucity of studies which have examined the human right to food in complex emergencies. 186 countries including those affected by both human made and natural disasters and countries who are donors of humanitarian relief aid adopted the Rome Declaration on Food Security and World Summit plan of Action reaffirming “ the right to adequate food and the fundamental right of everyone to be free from hunger”. The human right to adequate and nutritious food in refugee settings implies that every refugee has physical and economic access to sufficient food to provide the necessary nutrients for effective physical and physiological functions and achieve well being. There are many grounds for believing that the current humanitarian responses to disasters more often violate than respect the human right to adequate and nutritious food. Using elements of household food security as our working framework this paper focuses on the complex ethical and moral questions raised by the conventional humanitarian assistance framework and in particular the issue of human right to food and household food security in refugee settings.

Quantum cryptography - one step closer to reality

Most of cryptographic techniques today provide secure enough communications in society. However, none of them can provide unconditional security (except One-Time pad, which is the only such mechanism). They all have weaknesses. That is why they should be consistently updated and renovated along with changes in technology.

However, the quantum computers have potential to completely revolutionize cryptography. They would be so powerful that all complex computations and mathematical problems on which current cryptography rely, would become trivial. They would be able to solve them in a matter of seconds. At the same time quantum cryptography would offer perfectly secure communication.

This paper is brief introduction to quantum computing, quantum cryptography, and to existing quantum technology.
