Feminist poetics : symbolism in an emblematic journey reflecting self and vision

My thesis tilled Feminist Poetics: Symbolism in an Emblematic Journey Reflecting Self and Vision, consists of thirty oil paintings on canvas, several preparatory sketches and drawings in different media on paper, and is supported and elucidated by an exegesis. The paintings on unframed canvases reveal mise en scčnes and emblems that present to the viewer a drama about links between identities, differences, relationships and vision. Images of my daughter, friends and myself fill single canvases, suites of paintings, diptyches and triptychs. The impetus behind my research derives from my recognition of the cultural means by which women's experience is excluded from a representational norm or ideal. I use time-honoured devices, such as, illusionist imagery, aspects of portraiture, complex fractured atmospheric space, paintings and drawings within paintings, mirrors and reflective surfaces, shadows and architectural devices. They structure my compositions in a way that envelops the viewer in my internal world of ideas. Some of these features function symbolically, as emblems. A small part of the imagery relies on verisimilitude, such as my hands and their shadow and my single observing eye enclosed by my glasses. What remains is a fantasy world, ‘seen’ by the image of my other eye, or ‘faction’, based on memories and texts explaining the significance of ancient Minoan symbols. In my paintings, I base the subjects of this fantasy on my memories of the Knossos Labyrinth and matristic symbols, such as the pillar, snake, blood, eye and horn. They suggest the presence of a ritual where initiates descended into the adyton (holy of holies) or sunken areas in the labyrinth. The paintings attempt a ‘rewriting’ of sacrality and gender by adopting the symbolism of death, transformation and resurrection in the adyton. The significance of my emblematic imagery is that it constructs a foundation narrative about vision and insight. I sought symbolic attributes shared by European oil painting and Minoan antiquity. Both traditions share symbolic attributes with male dying gods in Greek myths and Medusa plays a central part in this linkage. I argue that her attributes seem identical to both those of the dying gods and Minoan goddesses. In the Minoan context these symbols suggest metaphors for the female body and the mother and daughter blood line. When the symbols align with the beheaded Medusa in a patriarchal context, both her image and her attributes represent cautionary tales about female sexuality that have repercussions for aspects of vision. In Renaissance and Baroque oil painting Medusa's image served as a vehicle for an allegory that personified the triumph of reason over the senses. In the twentieth century, the vagina dentata suggests her image, a personified image of irrational emotion that some male Surrealists celebrated as a muse. She is implicated in the male gaze as a site of castration and her representation suggests a symbolic form pertaining to perspective. Medusa's image, its negative sexual and violent connotations, seemed like a keystone linking iconographic codes in European oil painting to Minoan antiquity. I fused aspects of matristic Minoan antiquity with elements of European oil paintings in the form of disguised attribute gestures, objects and architectural environments. I selected three paintings, Dürer's Setf-Portrait, 1500, Gentileschi's Self-Portrait as the Allegory of Painting, 1630 and Velazquez's Las Meniruis, 1656 as models because 1 detected echoes of Minoan symbolism in the attributes of their subjects and backgrounds. My revision of Medusa's image by connecting it to Minoan antiquity established a feminist means of representation in the largely male-dominated tradition of oil painting. These paintings also suggested painting techniques that were useful to me. Through my representations of my emblematic journey I questioned the narrow focus placed on phallic symbols when I explored how their meanings may have been formed within a matricentric culture. I retained the key symbols of the patriarchal foundation narratives about vision but removed images of violence and their link to desire and replaced it with a ritual form of symbolic death. I challenged the binary oppositional defined Self as opposed to Other by constructing a complex, fluid Self that interacts with others. A multi-directional gaze between subjects, viewers and artist replaces the male gaze. Different qualities of paint, coagulation and random flow form a blood symbolism. Many layers of paint retaining some aspects of the Gaze and Glance, fuse and separate intermittently to construct and define form. The sense of motion and fluidity constructs a form of multi-faceted selves. The supporting document, the exegesis is in two parts. In the first part, I discuss the Minoan sources of my iconography and the symbolic gender specific meanings suggested by particular symbols and their changed meanings in European oil painting, I explain how I integrate Minoan symbols into European oil paintings as a form of disguised symbolism. In the second part I explain how my alternative use of symbolism and paint alludes to a feminist poetic.

Comparison of static and dynamic engine models on the transient performance of a passenger vehicle powertrain

This paper presents experimental and computational results obtained on the Ford Barra 190 4.0 litres I6 gasoline engine and on the Ford Falcon car equipped with this engine. Measurements of steady engine performance, fuel consumption and exhaust emissions were first collected using an automated test facility for a wide range of cam and spark timings vs. throttle position and engine speed. Simulations were performed for a significant number of measured operating points at full and part load by using a coupled Gamma Technologies GT-POWER/GT-COOL engine model for gas exchange, combustion and heat transfer. The fluid model was made up of intake and exhaust systems, oil circuit, coolant circuit and radiator cooling air circuit. The thermal model was made up of finite element components for cylinder head, cylinder, piston, valves and ports and wall thermal masses for pipes. The model was validated versus measured steady state air and fuel flow rates, cylinder pressure parameters, indicated and brake mean effective pressures, and temperature of metal, oil and coolant in selected locations. Computational results agree well with experiments, demonstrating the ability of the approach to produce fairly accurate steady state maps of BMEP and BSFC, as well as to optimize engine operation changing geometry, throttle position, cam and spark timing. Measurements of the transient performance and fuel consumption of the full vehicle were then collected over the NEDC cycle. Simulations were performed by using a coupled Gamma Technologies GT-POWER/GT-COOL/GT-DRIVE model for instantaneous engine gas exchange, combustion and heat transfer and vehicle motion. The full vehicle model is made up of transmission, driveshaft, axles, and car components and the previous engine model. The model was validated with measured fuel flow rates through the engine, engine throttle position, and engine speed and oil and coolant temperatures in selected locations. Instantaneous engine states following a time dependent demand for torque and speed differ from those obtained by interpolating steady state maps of BSFC vs. BMEP and speed. Computational results agree well with experiments, demonstrating the utility of the approach in providing a more accurate prediction of the fuel consumption over test cycles.

Do we challenge students enough? Model Solar vehicle project challenges potential engineers.

A major challenge to Australia and New Zealand is the perceived need to develop "knowledge economies" based on the expertise of university graduates,  especially engineers. However, many countries are finding less students are choosing to study engineering. At the same time, there is increasing concern about increased levels of greenhouse gases leading to global warming with species loss, rising sea levels and desertification being likely outcomes. Numerous competitions have been established aimed at attracting school students into science and engineering careers. Environmental groups have also sponsored educational activities to increase student awareness of alternative energy technologies. One activity which provides both a science and engineering challenge while also raising awareness of alternative energy and more efficient conversion of that energy for transport is the Model Solar Vehicle Challenge (MSVC). The Challenge, which provides a solar powered boat competition for younger students and a car race for the older ones, has involved thousands of Victorian school students since 1990 and students from all Australian states since 1993. Boats race in 2 or 3 lanes guided by an overhead wire in a 10 metre pool, and cars race 100 metres around a figure 8 track. Top boats average over 7 kph and cars reach speeds of 25 kph at the finish line. This paper will discuss the conduct of the Challenge, motivation of participants, the depth of learning which can be achieved and the effectiveness of the Challenge in encouraging students to continue with science subjects through school and to select engineering at university. It will also briefly discuss the lessons that can be learnt from the MSVC and applied to first year university courses.

Vehicle design for minimum societal harm

A design technique was developed to provide the best protection to all occupants in the real-world crashes that occur on Australian roads. A team of experts from around the world was marshalled to analyse crash data, develop new information on impact injury and a new computer optimising technique for simulation of side impact crashes.

Reducing energy consumption of vehicle air conditioning system by an energy management system

This paper presents an energy management system to reduce the energy consumption of a vehicle when its air conditioning system is in use. The system controls the mass flow rate of the air by dynamically adjusting the blower speed and air-gates opening under various heat and loads circumstances. Simulations were conducted for a travelling vehicle operating the air conditioning system without and with the developed energy management system. The results show that the comfort temperature within the cabin room is achieved for reduced amount of energy consumption.

A study on look-ahead control and energy management strategies in hybrid electric vehicles

Fuel efficiency in a hybrid electric vehicle requires a fine balance between usage of combustion engine and battery power. Information about the geometry of the road and traffic ahead can have a great impact on optimized control and the power split between the main parts of a hybrid electric vehicle. This paper provides a survey on the existing methods of control and energy management emphasizing on those that consider the look-ahead road situation and trajectory information. Then it presents the future trends in the control and energy management of hybrid electric vehicles.

Person-organization fit as a vehicle for knowledge sharing and creation

Tacit knowledge is difficult to transfer. It is also context specific. Hence it is often argued to be a key strategic asset and as such attention to how it is created and transferred in organisation in critical to strategists. The transfer of tacit knowledge is however still a challenge. It is known that shared communication and socialization are important processes in the transfer of tacit knowledge and person–organization fit (POF) is associated with such phenomena. Hence we argue that POF is likely to shape the transfer of tacit knowledge with higher levels of one resulting in higher levels of the other. We explore the interaction of tacit knowledge and POF fit and develop a matrix that suggests a complex interaction between the two.

Redox voltammetry of sub-parts per billion levels of Cu2+ at polyaspartate-modified gold electrodes

An electrochemical sensor for the detection of Cu2+ is reported which incorporates poly-l-aspartic acid (PLAsp) with 32–96 aspartate units as a selective ligand for the metal ion. PLAsp is covalently attached to a gold electrode modified with a monolayer of 3-mercaptopropionic acid using carbodiimide coupling via an N-hydroxysuccinimide (NHS) ester intermediate. The acid side groups and deprotonated peptide nitrogens on two aspartate moieties are thought to be primarily responsible for chelation of Cu2+, which remains bound when reduced to Cu+. A consequence of the multiple binding points that are available with a polypeptide is the low detection limit. The lowest concentration detected was 3 nM (0.2 ppb) achieved with Osteryoung square wave voltammetry. This detection limit compares favourably with that of ICP-OES and previously reported cysteine-modified electrodes. Analysis of tap and lake water samples using the PLAsp-modified electrode agreed well with ICP-OES analysis of the same samples.
