description: The need for maintenance is based on the wear of components of machinery. If this need can be defined reliably beforehand so that no unpredicted failures take place then the maintenance actions can be carried out economically with mini-mum disturbances to production. There are two basic challenges in solving the above. First understanding the development of wear and failures, and second managing the measurement and diagnosis of such parameters that can reveal the development of wear. In principle the development of wear and failures can be predicted through monitoring time, load or wear as such. Moni-toring time is not very efficient, as there are only limited numbers of components that suffer from aging which as such is the result of chemical wear i.e. changes in the material. In most cases the loading of components influences their wear. In principle the loading can be stable or varying in nature. Of these two cases the varying load case is much more challenging than the stable one. The monitoring of wear can be done either directly e.g. optical methods or indirectly e.g. vibration. Monitoring actual wear is naturally the most reliable approach, but it often means that additional investments are needed. The paper discusses how the monitoring of wear and need for maintenance can be done based on the use of Cyber Physical Systems.

description: The physical concept of locality is first analyzed in the special relativistic quantum regime, and compared with that of microcausality and the local commutativity of quantum fields. Its extrapolation to quantum general relativity on quantum bundles over curved spacetime is then described. It is shown that the resulting formulation of quantum-geometric locality based on the concept of local quantum frame incorporating a fundamental length embodies the key geometric and topological aspects of this concept. Taken in conjunction with the strong equivalence principle and the path-integral formulation of quantum propagation, quantum-geometric locality leads in a natural manner to the formulation of quantum-geometric propagation in curved spacetime. Its extrapolation to geometric quantum gravity formulated over quantum spacetime is described and analyzed.

HORIZON 2020

description: HIT2GAP is a four-year project which began in September 2015 and will run to September 2019. Its aim is to reduce the gap between the theoretical energy performance of buildings and the actual consumption in use.A typical offi ce building will use much more energy than the design team and client expected at the design and construction phases. HIT2GAP is seeking to reduce the gap between the anticipated energy use and what actually happens once a building is occupied. The reasons for ‘the gap’ are multifarious, ranging from compromises at the design and construction stages, to construction/ detailing and commissioning issues and unexpected user behaviours. Furthermore, renewable energy devices and other building services do not always work well with each other, and this can reduce the overall impact of devices installed to save energy.HIT2GAP cannot solve all of these problems, and while the project is focused specifi cally on eliminating energy profl igacy in buildings, it also aims to identify other contributory factors.

description: We simulate self-reproducing micellar systems using a recently introduced lattice-gas automaton. This dynamical model correctly describes the equilibrium and non-equilibrium properties of mixtures of oil, water and surfactants. The simulations reported here mimic the experiments of Luisi et al. in which caprylate micelles are formed by alkaline hydrolysis of immiscible ethyl caprylate ester. As in the laboratory experiments, we find an extended induction period during which the concentration of micelles remains small; thereafter the ester is consumed very rapidly with concomitant production of micelles.

"Die Theorie des Verbundenen Feldes – Ein systemischer Blick auf Gravitation, Ordnung und Bewegung"
Creators: name: Schiffers, Daniel
Publisher: name: Zenodo
Year: 2025

description: Diese Arbeit beschreibt eine systemische Theorie über die Entstehung von Ordnung und Bewegung im Universum – basierend auf dem Gedanken, dass Beziehung nicht aus Kräften oder Gesetzen entsteht, sondern durch bloße Anwesenheit.

Die Theorie des Verbundenen Feldes betrachtet Gravitation, Stabilität und Wandel als emergente Effekte eines dynamischen Beziehungsnetzes zwischen Objekten.

Sie ist kein Ersatz bestehender Modelle, sondern eine Ergänzung und Erweiterung – und bietet neue Perspektiven auf Phänomene wie Systembruch, Dunkle Energie und Schwarze Löcher.

Der Text lädt ein, Realität als Resonanz zu denken – und die Rolle von Struktur und Zusammenhang neu zu betrachten.

Selenium in terrestrial ecosystems and implications for drastically disturbed land reclamation
Creators: name: Fisher, Scott E.
Publisher: name: The University of British Columbia
Year: 2009

description: Selenium (1) can be beneficial or toxic to plants and animals (including humans) depending on its concentration. It occurs in low crustal abundance in most geological materials but is found in higher concentrations in Cretaceous and early Tertiary age sedimentary rocks, tuffaceous sediments, roll front deposits, and in association with sulfide minerals in metaliferous deposits. In arid regions soils developed from such parent rocks can contain relatively high concentrations of selenium. Higher concentrations of selenium can occur in ecosystems impacted by human actives such as irrigation projects, air pollution, mining, or long term use of soil amendments (e.g. fly ash) containing elevated levels of selenium. Plant uptake and incorporation of selenium into tissue varies widely between species and ecotypes within plant species. Selenium may be essential to some plant species, particularly those that accumulate it in higher concentrations. The element is essential for animals but the range between deficiency and toxicity is relatively narrow. Selenium is frequently deficient in animal diets in higher moisture environments. In arid environments the higher dietary selenium intake from forage and water sources rarely leads to mortalities from acute selenium toxicity. To evaluate the impact of Se on land use several factors should be considered: 1) careful analytical definition of the total and available selenium content of earthen materials on the site; 2) identification of the new depositional environments for these materials; 3) description of post-disturbance planned and potential land uses; 4) an understanding of the components and interactions of the ecosystems.

description: We report theoretical studies of adiabatic population transfer using dressed spin states. Quantum optimal control using the algorithm of Chopped Random Basis (CRAB) has been implemented in a negatively charged diamond nitrogen vacancy center that is coupled to a strong and resonant microwave field. We show that the dressed spin states are highly effective in suppressing effects of spin dephasing on adiabatic population transfer. The numerical simulation also demonstrates that CRAB-based quantum optimal control can enable an efficient and robust adiabatic population transfer.

description: We describe energy--momentum conservation in relativistic perturbation theory in general FRW backgrounds with causal source terms, such as the presence of cosmic defect networks. We provide a prescription for a linear energy--momentum pseudo-tensor in a curved FRW universe, decomposing it using eigenfunctions of the Helmholtz equation. We also construct conserved vector densities for the conformal geometry of these spacetimes and relate these to our pseudo-tensor, demonstrating the equivalence of these two approaches. We also relate these techniques to the role played by residual gauge freedom in establishing matching conditions at early phase transitions, which we can express in terms of components of our pseudo-tensor. This formalism is concise and geometrically sound on both sub- and superhorizon scales, thus extending existing work to a physically (and numerically) useful context.

description: Recently Tracy and Widom conjectured [math.CO/9904042] and Johansson proved [math.CO/9906120] that the expected shape λof the semi-standard tableau produced by a random word in k letters is asymptotically the spectrum of a random traceless k by k GUE matrix. In this article we give two arguments for this fact. In the first argument, we realize the random matrix itself as a quantum random variable on the space of random words, if this space is viewed as a quantum state space. In the second argument, we show that the distribution of λis asymptotically given by the usual local limit theorem, but the resulting Gaussian is disguised by an extra polynomial weight and by reflecting walls. Both arguments more generally apply to an arbitrary finite-dimensional representation V of an arbitrary simple Lie algebra g. In the original question, V is the defining representation of g = su(k).

description: The problem to be considered is the stationar system of Navier-Stokes equations with uncertain parameters and uncertain computational domain. We research how uncertainties in the angle of attack, in the Mach number and in the geometry of the airfoil propagate in the solution. The uncertain solution of this problem (pressure, density, velocity etc) is approximated via random fields. Since the whole set of realisations of these random fields are too much information, we demonstrate an algorithm of their low-rank approximation. This algorithm, working on the fly, is based on the QR-decomposition and has a linear complexity. This low-rank approximation allows us an effective postprocessing (computation of the mean value, variance, exceedance probability) with drastically reduced memory requirements.

description: We report on the first experimental demonstration of enantioselective rotational control of chiral molecules with a laser field. In our experiments, two enantiomers of propylene oxide are brought to accelerated unidirectional rotation by means of an optical centrifuge. Using Coulomb explosion imaging, we show that the centrifuged molecules acquire preferential orientation perpendicular to the plane of rotation, and that the direction of this orientation depends on the relative handedness of the enantiomer and the rotating centrifuge field. The observed effect is in agreement with theoretical predictions and is reproduced in numerical simulations of the centrifuge excitation followed by Coulomb explosion of the centrifuged molecules. The demonstrated technique opens new avenues in optical enantioselective control of chiral molecules with a plethora of potential applications in differentiation, separation and purification of chiral mixtures.

This paper examines the effect of personality traits, as operationalized by the Big-five questionnaire, on the number, type, and severity of the identified usability issues, physiological signals (skin conductance), and subjective emotional ratings (valence-arousal).Twenty-four users interacted with a web service and then participated in a retrospective thinking aloud session. Results revealed that the number of usability issues is significantly affected by the Openness trait. Emotional Stability significantly affects the type of reported usability issues. Problem severity is not affected by any trait. Valence ratings are significantly affected by Conscientiousness, whereas Agreeableness, Emotional Stability and Openness significantly affect arousal ratings. Finally, Openness has a significant effect on the number of detected peaks in user's skin conductance.

description: Changing demands of the workplace require that schools teach students to think critically. The new Common Core State Standards stress that to prepare for college and careers, students must be capable of engaging in skilled evidence-based argumentation, which entails use of evidence to support one's own claims and to weaken arguments of the opposing position. In Study 1, middle-school students who had participated in a one or two-year curriculum designed to develop argumentation skills were recruited. Previous use of the curriculum had shown it effective in developing students' skills in supporting arguments with evidence.
      However, they displayed only limited use of evidence to address and weaken opponents' arguments, a finding replicated in the present study. A prompt was therefore instituted, explicitly instructing them to undertake this goal in a post-intervention essay assessment. This simple instruction enhanced middle school students' use of evidence-based arguments to weaken an opposing claim, indicating that the skill to do so was within their competence but they possibly were insufficiently aware of its relevance to use it without prompting.
      Study 2 was undertaken to determine whether a novice group of middle schoolers similarly needed only a prompt to display this skill critical to argumentive reasoning. They were provided with only minimal experience in discourse with peers on the same social issue used in Study 1 (whether cigarette sales should be banned), following which they were asked to write individual argumentive essays, first without any prompt and then with the prompt instructing them to attempt to weaken an opponent's position. In this group, essays following the prompt showed no greater use of arguments to weaken, compared to essays with no such instruction. Nor was there an effect of whether students' prior dialogs had been with agreeing or disagreeing peers. These results indicate that the weaknesses of Study 2 participants, in understanding the objectives of argumentation and in executing the strategies to achieve these objectives, were more fundamental and not ones remediable by a simple prompt. Overall, the results of both studies thus point to the need for extended engagement and guided practice in order for students to master the skills of argument.
title: Lifelong learning as a transformative endeavour
title: how do part-time mature learners make sense of barriers and opportunities in higher education
titleType: Subtitle

description: The idea of the ‘lifelong learner’ has particular currency in Western economies, where citizens are expected to be work-ready at all times. Notwithstanding the “buzziness” of the term, the contemporary realities of engaging in higher education across the life-course are less well known and increasingly under pressure in the context of increasing fees, more limited student support, accessibility, and balancing study with the wider obligations of personal life. Enrolling as a part time, flexible lifelong learning student often requires major adjustments intellectually, socially, emotionally and financially. Thus, the purpose of this research is to explore the experiences of part-time mature adult students as lifelong learners in HE in Ireland (specifically in the IoT sector), in order to extend knowledge in this area and critically consider the extent to which the notion of the “lifelong learner” is being supported as part-time mature learners make sense of barriers and opportunities in HE. Indeed, whilst we have a considerable understanding of the benefits of adults participating in full-time higher education, far less information is available about what it means to study part-time and the particular challenges this mode of adult participation brings in the contemporary context. Ireland presents an important case study example because whilst it is performing well in relation to the numbers of young people continuing to tertiary level, it has much less reason to celebrate participation rates in lifelong learning. Ireland has only half the average rate of participation of the EU as a whole. Moreover, public policy is focused to encourage further participation and educators are increasingly responsible for finding ways to engage meaningfully with their part-time lifelong learning students. Taking these different issues as a jumping off point, using survey and interview data with existing part time students, this research examines the extent to which mature part-time students feel supported in becoming ‘lifelong learners’ in Ireland, and what this means in terms of the ways they position themselves, and are positioned by others, in this field. It will look specifically at the development of Lifelong Learning in HE and its current role in Irish education. The barriers to higher education are more numerous than might be imagined for part time mature students. It requires sensitivity and a real vocational commitment to help people to achieve their potential and embrace the opportunities HE brings. Research such as this can provide a roadmap in breaking down those barriers and it would be regrettable if it was not possible to carry this experience forward. The author hopes that the findings from this research will help to achieve this objective of improving the personal outcomes of part-time mature lifelong learning students and those of society more generally.

description: We present a scenario of the chemical enrichment of the solar neighborhood that solves the G-dwarf problem by taking into account constraints on a larger scale. We argue that the Milky Way disk within 10 kpc has been enriched to solar metallicity by a massive stellar population: the thick disk, which itself formed from a massive turbulent gaseous disk. The key new consideration is that the pre-enrichment provided by the thick disk is not related to the mass fraction of this stellar population at the solar radius, as is classically assumed in inside-out scenarios, but is actually related to the formation of the entire massive thick disk, due to the vigorous gas phase mixing that occurred during its formation. Hence, the fact that this population represents only 15-25% of the local stellar surface density today is irrelevant for `solving' the G-dwarf problem. The only condition for this scenario to work is that the thick disk was formed from a turbulent gaseous disk that permitted a homogeneous -- not radially dependent -- distribution of metals, allowing the solar ring to be enriched to solar metallicity. At the solar radius, the gas flowing from the outer disk combined with the solar metallicity gas left over from thick disk formation, providing the fuel necessary to form the thin disk at the correct metallicity to solve the G-dwarf problem. Chemical evolution at R$>$6 kpc, and in particular beyond the solar radius, can be reproduced with the same scheme. These results imply that the local metallicity distribution is not connected to the gas accretion history of the Milky Way. Finally, we argue that the Sun is the result of the evolution typical of stars in the disk beyond $\sim$6 kpc (i.e., also undergoing dilution), and has none of the characteristics of inner disk stars.

description: The retelling task is the first task in the Test for English Majors Band 4 Oral (TEM4-Oral), a nationwide English speaking test for undergraduate English major students in China. Despite its wide use, little work has been done on ensuring its validity. This is reflected in the absence of a systematic validation program or review since its launch in 1999 (Duan, 2011). In the case of the retelling task, the provision of a source story which candidates ‘retell’ raises concerns about the use of source material and how it is linked to language proficiency (e.g. Plakans & Gebril, 2012). This study examines the validity of the TEM4-Oral retelling task through analysing features of test-taker performance across four test administrations. Combining corpus analysis and qualitative explorations, it addresses how candidates’ proficiency levels are reflected in the discourse characteristics of their retellings. It also explores the consistency of scoring across task versions. Findings suggest significant differences in the discourse features of higher- and lower-ranked retellings, which partly supports the score interpretation from test-taker performance in the retelling task. On the other hand, some inconsistencies in candidates’ discourse features have been observed across administrations. This indicates that the generalisability of the task is threatened. This study constitutes an initial step in the validation process of TEM4-Oral. As well as shedding light on the design of the retelling task, it highlights the importance of test validation in the Chinese context, which would benefit thousands of people.

description: We study the classical and quantum theory of a class of nonlinear differential equations on chronology violating spacetime models in which space consists of finitely many discrete points. Classically, in the linear and weakly nonlinear regimes (for generic choices of parameters) we prove existence and uniqueness of solutions corresponding to initial data specified before the dischronal region; however, uniqueness (but not existence) fails in the strongly coupled regime. The evolution preserves the symplectic structure. The quantum theory is approached via the quantum initial value problem (QIVP); that is, by seeking operator-valued solutions to the equation of motion with initial data representing the canonical (anti)commutation relations. Using normal operator ordering, we construct solutions to the QIVP for both Bose and Fermi statistics (again for generic choice of parameters) and prove that these solutions are unique. For models with two spatial points, the resulting evolution is unitary; however, for a more general model the evolution fails to preserve the (anti)commutation relations and is therefore nonunitary. We show that this nonunitary evolution cannot be described using a superscattering operator with the usual properties. We present numerical evidence to show that the bosonic quantum theory can pick out a unique classical limit for certain ranges of the coupling strength, even when there are many classical solutions. We show that the quantum theory depends strongly on the choice of operator ordering. In addition, we show that our results differ from those obtained using the ``self-consistent path integral''. It follows that the path integral evolution does not correspond to a solution of the equation of motion.

description: Nerd abstract: Observational constraints on spacetime are reviewed, focusing on how the underlying physics (dark matter, dark energy, gravity) can be tested rather than assumed. Popular abstract: Space is not a boring static stage on which events unfold over time, but a dynamic entity with curvature, fluctuations and a rich life of its own which is a booming area of study. Spectacular new measurements of the cosmic microwave background, gravitational lensing, type Ia supernovae, large-scale structure, spectra of the Lyman alpha forest, stellar dynamics and x-ray binaries are probing the properties of spacetime over 22 orders of magnitude in scale. Current measurements are consistent with an infinite flat everlasting Universe containing about 30% cold dark matter, 65% dark energy and at least two distinct populations of black holes.

Localization and Equipartition of Energy in the beta-FPU Chain : Chaotic Breathers

description: The evolution towards equipartition in the $β$-FPU chain is studied considering as initial condition the highest frequency mode. Above an analytically derived energy threshold, this zone-boundary mode is shown to be modulationally unstable and to give rise to a striking localization process. The spontaneously created excitations have strong similarity with moving exact breathers solutions. But they have a finite lifetime and their dynamics is chaotic. These chaotic breathers are able to collect very efficiently the energy in the chain. Therefore their size grows in time and they can transport a very large quantity of energy. These features can be explained analyzing the dynamics of perturbed exact breathers of the FPU chain. In particular, a close connection between the Lyapunov spectrum of the chaotic breathers and the Floquet spectrum of the exact ones has been found. The emergence of chaotic breathers is convincingly explained by the absorption of high frequency phonons whereas a breather's metastability is for the first time identified. The lifetime of the chaotic breather is related to the time necessary for the system to reach equipartition. The equipartition time turns out to be dependent on the system energy density $ε$ only. Moreover, such time diverges as $ε^{-2}$ in the limit $ε\to 0$ and vanishes as $ε^{-1/4}$ for $ε\to \infty$.

Selenium in the Elk River Basin, British Columbia : a review of findings and discussion of implications for assessment and management

description: Despite 100 to 200 fold increases in waterborne selenium below coal mine operations in the Elk River basin, concentrations in sediments, attached algae, aquatic insects and fish tissues were only 2 to 5 times greater than reference sites. Selenium concentrations in Westslope cutthroat trout skeletal muscle and liver were higher in the near field populations and exceeded published toxic effects thresholds for fish tissue. Further study in 1998 compared the frequency of embryonic deformities and mortalities with the; Se concentration in the eggs of individual female cutthroat trout in an exposed and a reference population. Egg selenium concentrations ranged from 2.0 to 8.8 μg/g dry wt. in reference fish, and 8.7 to 81.3 μg/g dry wt. in exposed fish. Both reference and exposed populations showed low frequencies of deformities (<2.5%) and occasional high frequencies of mortalities (up to 100%) but no correlation with egg selenium. The lack of response in this population of cutthroat trout suggests an evolved tolerance to selenium at levels reported elsewhere to cause significant toxic effects. The findings of the Elk River studies provide evidence that development and application of universal criteria must be done with great caution. Management decisions made on residue data alone may be unnecessarily under or over protective. At this state it appears necessary that site specific studies must be carried out to verify the absence: or presence of effects.

This paper dicusses quantum noise in the context of speedmeter-a devise monitoring the speed of the testmass. The scheme proposed to overcome SQL in this case might be more practical than the methods based on monitoring position of the testmass.
