Literarische Grenzüberschreitungen : (un-)exakte Wissenschaften bei Brigitta Falkner
No full textDas Werk der österreichischen Autorin Brigitta Falkner beruht auf einem unerschöpflichen Prozess der Grenzüberschreitung und der Hybridisierung. Daraus folgt u. a. eine Erweiterung der Grenzen des Literarischen: Biologie, Mathematik, Physik und andere Wissenschaften werden überraschende Akteurinnen in der neuen 'Ordnung der Dinge', die Falkner in ihren Produktionen verwirklicht.The work of the Austrian author Brigitta Falkner is based on an infinite process of crossing borders and hybridization. The limits of literary work are thus extended by the inclusion of the scientific fields of biology, mathematics or physics, which become actors in the new 'order of things' present in Falkner's works of art
How to build complex, large-scale emulated networks
No full textThis paper describes AutoNetkit, an auto-configuration tool for complex network emulations using Netkit, allowing large-scale networks to be tested on commodity hardware. AutoNetkit uses an object orientated approach for router configuration management, significantly reducing the complexities in large-scale network configuration. Using AutoNetkit, a user can generate large and complex emulations quickly without errors.We have used AutoNetkit to successfully generate a number of different large networks with complex routing/security policies. In our test case, AutoNetkit can generate 100,000 lines of device configuration code from only 50 lines of high-level network specification code.Hung Nguyen, Matthew Roughan, Simon Knight, Nick Falkner, Olaf Maennel and Randy Bus

Slices and Snapshots
No full textANDREW CARNIE SLICES & SNAPSHOTS Andrew Carnie’s slide-dissolve installations tell stories that reflect upon our understanding of the workings of the human body. In a darkened space layered images appear and disappear on suspended screens, the developing display absorbing the viewer into an expanded sense of space and time through the slowly unfolding narratives that evolve before them. Slices & Snapshots is a collection of slide-dissolve works, the core elements of which are pairs of projectors set at opposite ends of a space, each casting sequences of images onto the layers of semi-translucent screens suspended between them. Narratives are created over time through images that surface onto the screens and then dissolve into slides projected from the other side. The sequential nature of Carnie’s work is rooted in his joint fascination with the historically pioneering work of photographer Eadweard Muybridge and in contemporary chronophotography - the use of photographic sequencing in modern scientific analysis. Contemporary science uses chronophotography to develop an understanding of the different biological functions of the body. Photographs, for example, are taken over time using fluorescent proteins, then combined into sequences, creating quick-time movies that act as tools for viewing the developing human form: the cells of the brain moving into their working position or muscle cells viewed ‘swimming’ to prescribed destinations. An understanding of the controls that influence these movements is reached by altering chemical concentrations and observing the diverse results. Modern scientific imaging is effecting how we perceive ourselves and developing new notions of ‘self’ through techniques like MRI and CT scanning, X-rays and Ultrasound. Taking these scientific techniques as a source, I attempt to provide a wider resonance, my work existing in the mediating world of the mind - somewhere between raw scientific data and our condition as human beings. Andrew Carnie 2004 2004 marks the centenary of the death of Eadweard Muybridge. Through his investigations into physical movement, Muybridge is considered one of the earliest scientific photographers as well as a pioneer of modern cinema. With this exhibition Carnie pays homage to the photographer, his life, his times and the compelling imagery he created. A RESEARCH PROJECT FROM THE FACULTY OF ART, DESIGN & MUSIC, KINGSTON UNIVERSITY Artist Biography: Andrew Carnie (b.1957) studied chemistry and painting at Warren Wilson College, North Carolina (USA) then zoology and psychology at Durham University (UK) before completing a Degree in Fine Art at Goldsmiths College and a Masters in Painting at the Royal College of Art, London. Since graduating Andrew has combined his studio based practice with ventures such as the Carnie Chapel Gallery (1986-88) and the Tram Depot Gallery (1994-96), working on various collaborative arts projects, as a consultant for Greater London Arts and a teacher at Winchester School of Art (UK). Recent projects include: Head On (2002) Science Museum/Wellcome Foundation, London - working with neuro-scientists at the Medical Research Centre for Developmental Neurology, Kings College London; Alight at Royal Victoria Dock (2002) - a 50m long multi-media video work, as part of the group No Limits; Embark (2002) Millais Gallery, Southampton - a solo-show of large paintings and travel-works; Disperse (2002) - a work, produced for the School of Hygiene and Tropical Medicine London, looking at how the body might be physically dispersed at the point of death and rendered back into atomic particles; Complex Brain: Spreading Arbor (2003) - a joint project looking at the migration of neurones in the human brain, with neurologists Dr Richard Wingate (Kings College London) and Nick Didovsky (Rocafella University New York) and funded by the Wellcome Trust. His work is represented in collections in England, Germany, and the USA. Eye: Through The Mirror Darkly is a video projection work. The images are projected onto a voile screen in the form of a truncated cone, the smaller part of the cone fixed to the wall the larger circumference floating, perpendicular to the floor, away from the wall and into the gallery. The images consist of a series of stills all based around medical-imaging techniques used in medical science. The work is part of a project I am involved in looking at the ways concept of self have changed through images and ideas spawned by science
On the Darboux integrability of Blasius and Falkner-Skan equation
No full textAgraïments: The second author is partially supported by FCT through CAMGDS, Lisbon.We study the Darboux integrability of the celebrated Falkner-Skan equation f''' + ff'' + λ(1-f'2) = 0, where λ is a parameter. When λ = 0 this equation is known as Blasius equation. We show that both differential systems have no first integrals of Darboux type. Additionally we compute all the Darboux polynomials and all the exponential factors of these differential equations

Verifiable policy-defined networking for security management
No full textA common goal in network-management is security. Reliable security requires confidence in the level of protection provided. But, many obstacles hinder reliable security management; most prominent is the lack of built-in verifiability in existing management paradigms. This shortfall makes it difficult to provide assurance that the expected security outcome is consistent pre- and post-deployment. Our research tackles the problem from first principles: we identify the verifiability requirements of robust security management, evaluate the limitations of existing paradigms and propose a new paradigm with verifi- ability built in: Formally-Verifiable Policy-Defined Networking (FV-PDN). In particular, we pay attention to firewalls which protect network data and resources from unauthorised access. We show how FV-PDN can be used to configure firewalls reliably in mission critical networks to protect them from cyber attacks.Dinesha Ranathunga, Matthew Roughan, Phil Kernick, Nick Falkner, Hung Nguyen, Marian Mihailescu, Michelle McClintoc
Is comprehension or application the more important skill for first-year computer science students?
No full textTime and performance data was collected on a class of 147 Computer Science 1B students, where students carried out a design and programming task based on one that had been seen in a previous examination. Given that students had previously worked through the task, we assessed their comprehension of that material in this assignment. We were then able to collect the performance data and correlate this with the examination marks for the student to determine if there was a relationship between performance in the examination and performance in this practical. We were also able to correlate the performance in this practical with the time taken to complete the practical, and with the student’s statement as to whether they remembered how they had solved it in their previous attempt. By doing this, we discovered that the students who remembered having solved it previously had a significantly higher mean examination mark than those students who claimed not to remember it. Unsurprisingly, students also performed better in this assignment if they had performed better in the examination. The mean time to complete the task was significantly less for those students who claimed to remember the task. In this task, the comprehension of the original material and the ability to recall it was of more importance than the ability to apply knowledge to an unseen problem.Nickolas J. G. Falkne
Pressure Output Feedback Control of Tollmien–Schlichting Waves in Falkner–Skan Boundary Layers
No full textThis paper investigates the use of point wall pressure measurements for output feedback control of Tollmien–Schlichtingwaves in Falkner–Skan boundary layers.Anewapproach is presented for input–outputmodeling of the linear dynamics of the fluid system and the integration withH2∕Linear Quadratic Gaussian reduced-order control design. The pressure output at the wall is related with the global perturbation velocity field through the linearized pressure Poisson equation. A Kalman filter is subsequently used to obtain time-resolved estimates of the velocity field using pressure information at discrete points at the wall. The estimated field is in turn used to calculate an optimal state feedback control to suppress the instabilities. The controller is designed in a feedforward, a feedback, and a combined feedforward/feedback actuator/sensor configuration. It is shown that combined feedforward/feedback control gives the best tradeoff between robust performance and robust stability in the presence of uncertainties in the Reynolds number and the pressure gradient. Robust performance in off-design conditions is enhanced compared to feedforward control, whereas robust stability is enhanced compared to feedback control.Control & SimulationAerodynamic
