Automatic application object migration in sensor networks

Object migration in wireless sensor networks has the potential to reduce energy consumption for a wireless sensor network mesh. Automated migration reduces the need for the programmer to perform manual static analysis to find an efficient layout solution. Instead, the system can self-optimise and adjust to changing conditions. This paper describes an automated, transparent object migration system for wireless sensor networks, implemented on a micro Java virtual machine. The migration system moves objects at runtime around the sensor mesh to reduce communication overheads. The movement of objects is transparent to the application developer. Automated transparent object migration is a core component of Hydra, a distributed operating system for wireless sensor networks that is currently under development. Performance of the system under a complex performance test scenario using a real-world dataset of seismic events is described. The results show that under both simple and complex conditions the migration technique can result in lower data traffic and consequently lower overall energy cost

Distributed OpenGL Rendering in Network Bandwidth Constrained Environments

Display walls made from multiple monitors are often used when very high resolution images are required. To utilise a display wall, rendering information must be sent to each computer that the monitors are connect to. The network is often the performance bottleneck for demanding applications, like high performance 3D animations. This paper introduces ClusterGL; a distribution library for OpenGL applications. ClusterGL reduces network traffic by using compression, frame differencing and multi-cast. Existing applications can use ClusterGL without recompilation. Benchmarks show that, for most applications, ClusterGL outperforms other systems that support unmodified OpenGL applications including Chromium and BroadcastGL. The difference is larger for more complex scene geometries and when there are more display machines. For example, when rendering OpenArena, ClusterGL outperforms Chromium by over 300% on the Symphony display wall at The University of Waikato, New Zealand. This display has 20 monitors supported by five computers connected by gigabit Ethernet, with a full resolution of over 35 megapixels. ClusterGL is freely available via Google Code

Housing Turnover and First-home Buyers

While housing turnover varies over time, on average, around 6 per cent of the housing stock, or around 500 000 dwellings, change ownership each year. In 2009, first-home buyers accounted for an unusually large share of this turnover, although this share has since declined. As first-home buyers make greater use of mortgages to fund purchases than do repeat buyers, this shift in the composition of turnover helps to explain the recent divergence in movements in housing prices and loan approvals.housing market; housing turnover; first-home buyers

Nietzsche, Unconscious Processes, and Non-Linear Individuation

This thesis attempts to create an ontology of the self using Nietzsche’s concept of will-to-power forces, which operate in the individual unconsciously, leading to non-linear individuation resulting from responding or participating in chance events. Individuation results non-linearly because of Nietzsche’s claim that the “Deed has no doer” and that subjects and thoughts rely on fictitiously created causal chains, but that in actuality there are nothing but chance events and competing forces of nature which shape the individual into non-linear directions. The individual can only respond as creatively as possible to moments which arise, once loss of ultimate control is embraced. The main original points in this thesis are the interpretations that Nietzsche’s will-to-power acts as unconscious processes in individuals, and that non-linear individuation results from the directions which are taken during the participation and mastery of chance events

Introducing magazines and/as media : the aesthetics and politics of serial form

In her recent book on the ongoing relationship between modernism and media, Jessica Pressman makes the convincing claim that modernism—as a "strategy of innovation that employs the media of its time to reform and refashion older literary practices in ways that produce new art—is "centrally about media" (3–4 emphasis added). Pressman is not the first to link modernist aesthetic innovation to the rapid transformation of media technologies at the turn of the twentieth century; she identifies her indebt - edness to media scholars including Friedrich Kittler, Lev Manovich, and Marshall McLuhan, all of whom engage with the new discourse networks afforded by the rise of phonographs, radio, and cinema

Being in the hidden third: Insights into transdisciplinary ontology

This paper reflects two transdisciplinary (TD) scholars’ attempts to glean deeper insights into Nicolescu’s transdisciplinary ontology (i.e., multiple Levels of Reality and the Hidden Third). Respecting that Nicolescu’s Hidden Third represents the convergence of quantum physics, philosophy, and inner experiences, one TD scholar explored ‘What is it like to be in the Hidden Third?’ by expanding on Nicolescu’s constructs of cyber-space-time and transhumanism, which are grounded in quantum physics. The other TD scholar tendered philosophical insights by offering the idea of ontological emergence and the act of becoming as informed by the transcendentals. The intent was to understand ‘the being of being’ or perhaps ‘the being of becoming.’ The richness of Nicolescu’s ontological thinking offers a range of interpretation and we are grateful for the opportunity to feed off his methodological genius to respectively flourish through questions, clarification and truth seeking

Changes in visual and sensory-motor resting-state functional connectivity support motor learning by observing.

Motor learning occurs not only through direct first-hand experience but also through observation (Mattar AA, Gribble PL. Neuron 46: 153-160, 2005). When observing the actions of others, we activate many of the same brain regions involved in performing those actions ourselves (Malfait N, Valyear KF, Culham JC, Anton JL, Brown LE, Gribble PL. J Cogn Neurosci 22: 1493-1503, 2010). Links between neural systems for vision and action have been reported in neurophysiological (Strafella AP, Paus T. Neuroreport 11: 2289-2292, 2000; Watkins KE, Strafella AP, Paus T. Neuropsychologia 41: 989-994, 2003), brain imaging (Buccino G, Binkofski F, Fink GR, Fadiga L, Fogassi L, Gallese V, Seitz RJ, Zilles K, Rizzolatti G, Freund HJ. Eur J Neurosci 13: 400-404, 2001; Iacoboni M, Woods RP, Brass M, Bekkering H, Mazziotta JC, Rizzolatti G. Science 286: 2526-2528, 1999), and eye tracking (Flanagan JR, Johansson RS. Nature 424: 769-771, 2003) studies. Here we used a force field learning paradigm coupled with resting-state fMRI to investigate the brain areas involved in motor learning by observing. We examined changes in resting-state functional connectivity (FC) after an observational learning task and found a network consisting of V5/MT, cerebellum, and primary motor and somatosensory cortices in which changes in FC were correlated with the amount of motor learning achieved through observation, as assessed behaviorally after resting-state fMRI scans. The observed FC changes in this network are not due to visual attention to motion or observation of movement errors but rather are specifically linked to motor learning. These results support the idea that brain networks linking action observation and motor control also facilitate motor learning

Understanding public trust in services provided by community pharmacists relative to those provided by general practitioners: a qualitative study

Current UK initiatives, which aim to implement a range of pharmacist-led services, are undermined by lack of public trust. It seems improbable that the public will trust pharmacists to deliver unfamiliar services, which are perceived to be ‘high risk’, unless health systems change in a way that promotes trust in pharmacists. This may be achieved by increasing the quality and quantity of patient interactions with pharmacists and gaining GP support for extended pharmacy services
