Ασταθής ροή
Τεχνική PIV

description: Στο πλαίσιο της διπλωματικής αυτής εργασίας μελετήθηκε πειραματικά το πεδίο ροής (χρήση μετρητικής τεχνικής 2D-PIV) ενός ηλεκτρικά αγώγιμου ρευστού υπό την παρουσία ηλεκτρικού και μαγνητικού πεδίου. Το ρευστό ήταν διάλυμα αλατιού σε νερό, με αναλογία 15% κατά βάρος, τοποθετημένο σε δεξαμενή κατασκευασμένη από Plexiglas, με διαστάσεις 45 mm x 55 mm, βάθους 6 mm, με ελεύθερη επιφάνεια. Δυο κατακόρυφες πλάκες αλουμινίου σε απόσταση 45 mm αποτελούσαν τα ηλεκτρόδια της διάταξης, τα οποία με τη βοήθεια πηγής συνεχούς ρεύματος προκαλούσαν ηλεκτρικό ρεύμα μέσω του ρευστού, έντασης έως 1.2A και μέγιστης τάσης 14V. Κάτω από τη δεξαμενή ήταν τοποθετημένοι μόνιμοι μαγνήτες σχήματος ορθογώνιου παραλληλεπιπέδου, μαγνητικής επαγωγής 50 mT σε απόσταση 6 mm από την επιφάνειά τους, για την παραγωγή κατακόρυφου μαγνητικού πεδίου, χωρικά μεταβαλλόμενου. Χρησιμοποιήθηκε επίσης και ένας τοροειδής μαγνήτης. Υπό τη δράση των δυνάμεων Lorentz, το ρευστό τίθετο σε κίνηση. Κύριο χαρακτηριστικό της ροής ήταν η παρουσία δινών των οποίων ο αριθμός, η θέση και η κυκλοφορία μεταβάλλονταν με τον χρόνο. Χρησιμοποιήθηκαν τρεις διατάξεις μαγνητών και έγινε μέτρηση του πεδίου ταχυτήτων στο μέσον του βάθους του ρευστού δηλ. σε απόσταση 3 mm από τον πυθμένα. Βασικά συμπεράσματα: α) Στη διάταξη 4 μαγνητών, αρχικώς το πεδίο αποτελείται από 8 δίνες, με τα κέντρα τους να βρίσκονται σε δυο παράλληλες γραμμές κάθετες στο ηλεκτρικό ρεύμα, αλλά αργότερα μειώνεται ο αριθμός τους σε 4 μεγάλες δίνες. Αυξανόμενης της έντασης του ηλεκτρικού ρεύματος, οι ταχύτητες του ρευστού και οι διαταρχές τους αυξάνουν (μέγιστη ταχύτητα 50 mm/s και τυπική απόκλιση 25 mm/s). Η μέση κινητική ενέργεια του πεδίου ροής (70 έως 500 mm2 /s 2 ) αυξάνει με γρήγορο ρυθμό αρχικώς, αλλά στη συνέχεια τείνει σε μια τιμή μέσω διακυμάνσεων. β) Στη διάταξη των 10 μαγνητών, αρχικώς το πεδίο αποτελείται από 4 δίνες με τα κέντρα τους να είναι σε μια ευθεία κάθετη στην κατεύθυνση του ηλεκτρικού ρεύματος. Στη συνέχεια, ο αριθμός των δινών μειώνεται σε 2 δίνες ίδιας φοράς κυκλοφορίας, με τα κέντρα τους να βρίσκονται σε μια ευθεία που σχηματίζει μικρή γωνία με τις πλάκες των ηλεκτροδίων. Αυξανόμενης της τάσης, οι ταχύτητες του ρευστού και οι διαταραχές τους αυξάνουν, παίρνοντας η κινητική ενέργεια μεγαλύτερες τιμές (ακόμα και διπλάσιες) σε σχέση με την περίπτωση των 4 μαγνητών. γ) Στη διάταξη του τοροειδούς μαγνήτη, το πεδίο ροής αποτελείται από 4 δίνες με τα κέντρα τους να βρίσκονται κοντά στις 4 γωνίες της ορθογωνικής δεξαμενής από τις οποίες οι δυο δίνες είναι ισχυρότερες. Στην διάταξη αυτή, δεν παρουσιάστηκε μείωση του αριθμού των δινών με τον χρόνο. Αποσυνδέοντας την πηγή ρεύματος, η ροή επιβραδύνεται και οι αρχικά 4 δίνες μετατρέπονται σε 1 λίγο πριν ακινητοποιηθεί το ρευστό.

description: Isosurface visualization is fundamental for exploring and analyzing 3D volumetric data. Marching cubes (MC) algorithms with linear interpolation are commonly used for isosurface extraction and visualization. Although linear interpolation is easy to implement, it has limitations when the underlying data is complex and high-order, which is the case for most real-world data. Linear interpolation can output vertices at the wrong location. Its inability to deal with sharp features and features smaller than grid cells can lead to an incorrect isosurface with holes and broken pieces. Despite these limitations, isosurface visualizations typically do not include insight into the spatial location and the magnitude of these errors. We utilize high-order interpolation methods with MC algorithms and interactive visualization to highlight these uncertainties. Our visualization tool helps identify the regions of high interpolation errors. It also allows users to query local areas for details and compare the differences between isosurfaces from different interpolation methods. In addition, we employ high-order methods to identify and reconstruct possible features that linear methods cannot detect. We showcase how our visualization tool helps explore and understand the extracted isosurface errors through synthetic and real-world data.

description: The direction of cascades in a two-dimensional model that takes electron inertia and ion sound Larmor radius into account is studied, resulting in analytical expressions for the absolute equilibrium states of the energy and helicities. It is found that typically both the energy and magnetic helicity at scales shorter than electron skin depth have direct cascade, while at large scales the helicity has an inverse cascade as established earlier for reduced magnetohydrodynamics (MHD). It is also found that the introduction of gyro-effects allows for the existence of negative temperature (conjugate to energy) states and the condensation of energy to the large scales. Comparisons between two- and three-dimensional extended MHD models (MHD with two-fluid effects) show qualitative agreement between the two.

Probing Transverse-Momentum Dependent Evolution With Groomed Jets

description: We propose an observable which involves measuring the properties (transverse momentum $p_{h\perp}$ and energy fraction $z_h$) of an identified hadron inside a groomed jet. The jet is identified with an anti-kT/CA algorithm and is groomed by implementing the modified mass drop procedure with an energy cut-off parameter $z_{cut}$. The transverse momentum of the hadron inside the jet is measured with respect to the groomed jet axis. We obtain a factorization theorem in the framework of Soft Collinear Effective Theory (SCET), to define a Transverse Momentum Dependent Fragmenting Jet Function (TMDFJF). The TMDFJF is factorized into collinear and collinear soft modes by matching onto SCET$_+$. We resum large logarithms in $E_J/p_{h\perp}$, where $E_J$ is the ungroomed jet energy, to NLL accuracy and apply this formalism for computing the shape of the $p_{h\perp}$ distribution of a pion produced in an $e^+ +e^-$ collision. We observe that the introduction of grooming makes this observable insensitive to non-global logarithms and particularly sensitive to non-perturbative physics of the transverse momentum dependent evolution at low values of $p_{h\perp}$, which can be probed in the variation of the cut-off parameter $z_{cut}$ of the groomer. We discuss how this observable can be used to distinguish between non-perturbative models that describe universal TMD evolution and provide a window into the three dimensional structure of hadrons.

description: The optimal distance measure for a given discrimination task under the nearest neighbor framework has been shown to be the likelihood that a pair of measurements have different class labels [S. Mahamud et al., (2002)]. For implementation and efficiency considerations, the optimal distance measure was approximated by combining more elementary distance measures defined on simple feature spaces. We address two important issues that arise in practice for such an approach: (a) What form should the elementary distance measure in each feature space take? We motivate the need to use the optimal distance measure in simple feature spaces as the elementary distance measures; such distance measures have the desirable property that they are invariant to distance-respecting transformations, (b) How do we combine the elementary distance measures ? We present the precise statistical assumptions under which a linear logistic model holds exactly. We benchmark our model with three other methods on a challenging face discrimination task and show that our approach is competitive with the state of the art.

description: BACKGROUND Recent technological advances in deep brain stimulation (DBS) (e.g., directional leads, multiple independent current sources) lead to increasing DBS-optimization burden. Techniques to streamline and facilitate programming could leverage these innovations. OBJECTIVE We evaluated clinical effectiveness of algorithm-guided DBS-programming based on wearable-sensor-feedback compared to standard-of-care DBS-settings in a prospective, randomized, crossover, double-blind study in two German DBS centers. METHODS For 23 Parkinson's disease patients with clinically effective DBS, new algorithm-guided DBS-settings were determined and compared to previously established standard-of-care DBS-settings using UPDRS-III and motion-sensor-assessment. Clinical and imaging data with lead-localizations were analyzed to evaluate characteristics of algorithm-derived programming compared to standard-of-care. Six different versions of the algorithm were evaluated during the study and 10 subjects programmed with uniform algorithm-version were analyzed as a subgroup. RESULTS Algorithm-guided and standard-of-care DBS-settings effectively reduced motor symptoms compared to off-stimulation-state. UPDRS-III scores were reduced significantly more with standard-of-care settings as compared to algorithm-guided programming with heterogenous algorithm versions in the entire cohort. A subgroup with the latest algorithm version showed no significant differences in UPDRS-III achieved by the two programming-methods. Comparing active contacts in standard-of-care and algorithm-guided DBS-settings, contacts in the latter had larger location variability and were farther away from a literature-based optimal stimulation target. CONCLUSION Algorithm-guided programming may be a reasonable approach to replace monopolar review, enable less trained health-professionals to achieve satisfactory DBS-programming results, or potentially reduce time needed for programming. Larger studies and further improvements of algorithm-guided programming are needed to confirm these results.
Induction of supernova-like explosions by gamma-ray bursts in close binary systems

description: We propose that a gamma-ray burst in one member of a binary may induce a supernova-like explosion of a close, white-dwarf companion. Such an explosion might be brought about in rather light companions, which cannot undergo the standard accretion-induced explosion. This would give some GRB-associated supernova an appearance rather unlike that of the typical Type I. GRB 980425, if indeed associated with SN 1998bw, is too weak to have produced it through our proposed mechanism.

description: We developed a robust control policy design method in high-dimensional state space by using differential dynamic programming with a minimax criterion. As an example, we applied our method to a simulated five link biped robot. The results show lower joint torques from the optimal control policy compared to a hand-tuned PD servo controller. Results also show that the simulated biped robot can successfully walk with unknown disturbances that cause controllers generated by standard differential dynamic programming and the hand-tuned PD servo to fail. Learning to compensate for modeling error and previously unknown disturbances in conjunction with robust control design is also demonstrated.

Approximation beats concentration? An approximation view on inference with smooth radial kernels

description: Positive definite kernels and their associated Reproducing Kernel Hilbert Spaces provide a mathematically compelling and practically competitive framework for learning from data. In this paper we take the approximation theory point of view to explore various aspects of smooth kernels related to their inferential properties. We analyze eigenvalue decay of kernels operators and matrices, properties of eigenfunctions/eigenvectors and "Fourier" coefficients of functions in the kernel space restricted to a discrete set of data points. We also investigate the fitting capacity of kernels, giving explicit bounds on the fat shattering dimension of the balls in Reproducing Kernel Hilbert spaces. Interestingly, the same properties that make kernels very effective approximators for functions in their "native" kernel space, also limit their capacity to represent arbitrary functions. We discuss various implications, including those for gradient descent type methods. It is important to note that most of our bounds are measure independent. Moreover, at least in moderate dimension, the bounds for eigenvalues are much tighter than the bounds which can be obtained from the usual matrix concentration results. For example, we see that the eigenvalues of kernel matrices show nearly exponential decay with constants depending only on the kernel and the domain. We call this "approximation beats concentration" phenomenon as even when the data are sampled from a probability distribution, some of their aspects are better understood in terms of approximation theory.
title: Essays in the philosophy of motivation, normativity, and self-knowledge
Creators: name: Kinakin, Matthew
Publisher: name: University of Glasgow
Year: 2024

description: This thesis comprises three distinct and substantial essays concerning motivation, normativity, and self-knowledge. Generally speaking, this thesis focuses on how agents can access particular facts about themselves—e.g., why they acted the way they acted or that a particular experience is bad-for-them. In particular, I show how the motivational and normative nature of certain mental states like our motivating reasons and unpleasant pains interact in unanticipated ways with foundational questions about the nature of phenomenal consciousness—“what it is like” to undergo this or that experience—with questions of self-knowledge—how we are aware of, and come to know, the mental states we’re in—and with questions concerning moral knowledge—how we come to know moral facts.

Take, for instance, the action of taking a painkiller or the formation of a new belief. If I asked you why you took a painkiller or why you formed the belief, you would be able to, in an immediate and direct sense, know why you did those things. Not only do you know what your reasons are, but you seem to know your reasons in a special way, again, in a sense that is immediate and direct. Furthermore, some of our mental states seem to be bad states to be in. Take, again, your unpleasant pain: you want to end it because it’s bad. So, it seems, then, that you also have knowledge of the badness of your unpleasant pain.

But these claims are not without controversy. For some deny that we know our own reasons in a special way distinct from how we know of other’s reasons. The first aim of this thesis is to critically assess a recent attempt to defend the claim that we do have some special, direct, and immediate knowledge of our reasons. But insofar as we construe the nature of why we believe and do things—i.e., our reasons—in a specific way, I argue that defending that picture likely fails.

Furthermore, turning back to our phenomenal experiences, it turns out that once we understand the nature of our phenomenal experiences—e.g., unpleasant pains—along particular representationalist lines, explaining the motivational and normative facts implicit in our painkiller-taking action becomes increasingly implausible. The second aim of the thesis argues that insofar as we are concerned with accommodating such motivational and normative facts, we ought to abandon a particular brand of representationalism about phenomenal consciousness.

And lastly, I argue that once we fully appreciate the normative profile of a certain set of our mental states—e.g., the badness of unpleasant pain and the wrongness of an intention to lie—we are in a position to develop a novel account of moral knowledge. Specifically, I motivate taking seriously the idea that we can introspect normative facts.

description: Color vision deficiency (CVD) affects more than 4% of the population and leads to a different visual perception of colors. Though this has been known for decades, colormaps with many colors across the visual spectra are often used to represent data, leading to the potential for misinterpretation or difficulty with interpretation by someone with this deficiency. Until the creation of the module presented here, there were no colormaps mathematically optimized for CVD using modern color appearance models. While there have been some attempts to make aesthetically pleasing or subjectively tolerable colormaps for those with CVD, our goal was to make optimized colormaps for the most accurate perception of scientific data by as many viewers as possible. We developed a Python module, cmaputil, to create CVD-optimized colormaps, which imports colormaps and modifies them to be perceptually uniform in CVD-safe colorspace while linearizing and maximizing the brightness range. The module is made available to the science community to enable others to easily create their own CVDoptimized colormaps. Here, we present an example CVD-optimized colormap created with this module that is optimized for viewing by those without a CVD as well as those with redgreen colorblindness. This colormap, cividis, enables nearly-identical visual-data interpretation to both groups, is perceptually uniform in hue and brightness, and increases in brightness linearly.

Do dwarf spheroidal galaxies contain dark matter?

Publisher: name: arXiv
Year: 1996

description: The amount of dark matter in the four galactic dwarf spheroidals with large mass-to-light ratios is investigated. Sextans has a cut-off radius which is equal to the expected tidal radius, assuming a high mass-to-light ratio. This satellite very likely is dark matter dominated. Carina, Ursa Minor and Draco, on the other hand, cannot contain a dominating dark matter component if the observed 'extra-tidal' stars are located exterior to the tidal radii of these systems. The evidence for tidal stripping in the absence of dark matter is also supported by the fact that the observed cut-off radii of all three satellites are equal to their tidal radii, assuming a low, globular cluster like mass-to-light ratio. The large velocity dispersions of these galaxies, on the other hand, seem to provide strong evidence for a massive dark matter component. In this case, the 'extra-tidal' stars lie deeply embedded in the dark matter potential wells of the satellites. These stars then would represent a gravitationally bound, extended stellar component with unknown origin.

description: Atmospheric regions below a refractive boundary are hidden in limb observations. Refraction thus creates a gray continuum in the planet's transmission spectrum which can hide spectral features associated with sources of atmospheric opacity. We combine refractive theory with recent analytical advances describing the effects of surfaces and clouds on transmission spectra, to express the location of this boundary in atmospheric opacity space, both for atomic and molecular extinction, as well as collision-induced absorption. This allows one to quickly estimate how refraction affects spectral features in well-mixed atmospheres. We show that differences in the geometry of limb observations between solar system planets and exoplanets leads to different locations of this boundary, and that more than four extra scale heights of atmosphere are hidden in exoplanet transits compared to solar system observations of cold gas giants. We explore how the location of this refractive boundary in exoplanet transits changes in a well-mixed isothermal atmosphere with its temperature and composition, the spectral type of the planet's host star, and the size of the planet. We demonstrate that five extra scale heights of atmosphere are hidden in a terrestrial planet with a CO$_2$ atmosphere compared to a helium atmosphere, resulting in a flatter spectrum than from its smaller scale height alone. We provide results for a few exoplanets, notably those in the TRAPPIST-1 system, to help the scientific community estimate the impact of refraction on the size of spectral features without radiative transfer calculations, and thus help refine planned James Web Space Telescope observations.

description: Background—We have developed a novel miniature robotic device (HeartLander) that can navigate on the surface of the beating heart through a subxiphoid approach. This study investigates the ability of HeartLander to perform in vivo semiautonomous epicardial injections on the beating heart. Methods and Results—The inchworm-like locomotion of HeartLander is generated using vacuum pressure for prehension of the epicardium and drive wires for actuation. The control system enables semiautonomous target acquisition by combining the joystick input with real-time 3-dimensional localization of the robot provided by an electromagnetic tracking system. In 12 porcine preparations, the device was inserted into the intrapericardial space through a subxiphoid approach. Ventricular epicardial injections of dye were performed with a custom injection system through HeartLander’s working channel. HeartLander successfully navigated to designated targets located around the circumference of the ventricles (mean path length=51±25 mm; mean speed=38±26 mm/min). Injections were successfully accomplished following the precise acquisition of target patterns on the left ventricle (mean injection depth=3.0±0.5 mm). Semiautonomous target acquisition was achieved within 1.0±0.9 mm relative to the reference frame of the tracking system. No fatal arrhythmia or bleeding was noted. There were no histological injuries to the heart due to the robot prehension, locomotion, or injection. Conclusions–In this proof-of-concept study, HeartLander demonstrated semiautonomous, precise, and safe target acquisition and epicardial injection on a beating porcine heart through a subxiphoid approach. This technique may facilitate minimally invasive cardiac cell transplantation or polymer therapy in patients with heart failure.

description: The study of geometric hypergraphs gave rise to the notion of $ABAB$-free hypergraphs. A hypergraph $\mathcal{H}$ is called $ABAB$-free if there is an ordering of its vertices such that there are no hyperedges $A,B$ and vertices $v_1,v_2,v_3,v_4$ in this order satisfying $v_1,v_3\in A\setminus B$ and $v_2,v_4\in B\setminus A$. In this paper, we prove that it is NP-complete to decide if a hypergraph is $ABAB$-free. We show a number of analogous results for hypergraphs with similar forbidden patterns, such as $ABABA$-free hypergraphs. As an application, we show that deciding whether a hypergraph is realizable as the incidence hypergraph of points and pseudodisks is also NP-complete.

description: The study concentrated on using metakaolin and Industrial Waste Hypo sludge in concrete to improve its strength characteristics. Cement and fine aggregate were swapped out with metakaolin, a Pozzolanic substance, and Industrial Waste Hypo sludge, a byproduct of the manufacturing of titanium dioxide. To evaluate these waste items' effects on strength qualities, different dosages were added to the concrete mix. Concrete samples were put through physical testing in accordance with normal procedures, and their strength was assessed at various curing times. The addition of industrial wastes to concrete significantly improved its modulus of rupture, split tensile strength, and compressive strength, according to the results

description: The Cryogenic Underground Observatory for Rare Events (CUORE) experiment at Gran Sasso National Laboratory of INFN searches for neutrinoless double beta decay using TeO2 crystals as cryogenic bolometers. The sensitivity of the measurement heavily depends on the energy resolution of the detector, therefore the success of the experiment stands on the capability to provide an extremely low noise environment. One of the most relevant sources of noise are the mechanical vibrations induced by the five Pulse Tube cryocoolers used on the cryogenic system which houses the detectors. To address this problem, we developed a system to control the relative phases of the pulse tube pressure oscillations, in order to achieve coherent superposition of the mechanical vibrations transmitted to the detectors. In the following, we describe this method and report on the results in applying it to the CUORE system.

description: We report a spectroscopic orbit with period P = 3.52433 +/- 0.00027 days for the planetary companion that transits the solar-type star HD209458. For the metallicity, mass, and radius of the star we derive [Fe/H] = 0.00 +/- 0.02, M = 1.1 +/- 0.1 solar masses, and R = 1.3 +/- 0.1 solar radii. This is based on a new analysis of the iron lines in our HIRES template spectrum, and also on the absolute magnitude and color of the star, and uses isochrones from four different sets of stellar evolution models. Using these values for the stellar parameters we reanalyze the transit data and derive an orbital inclination of i = 85.2 +/- 1.4 degrees. For the planet we derive a mass of Mp = 0.69 +/- 0.05 Jupiter masses, a radius of Rp = 1.54 +/- 0.18 Jupiter radii, and a density of 0.23 +/- 0.08 grams per cubic cm.

description: Interesting experimental signatures of quantum cavity optomechanics arise because the quantum back-action induces correlations between incident quantum shot noise and the cavity field. While the quantum linear theory of optomechanics (QLT) has provided vital understanding across many experimental platforms, in certain new set-ups it may be insufficient: analysis in the time domain may be needed, but QLT obtains only spectra in frequency space; and nonlinear behavior may be present. Direct solution of the stochastic equations of motion in time is an alternative, but unfortunately standard methods do not preserve the important optomechanical correlations. We introduce two-timescale stochastic Langevin (T2SL) propagation as an efficient and straightforward method to obtain time traces with the correct correlations. We show that T2SL, in contrast to standard stochastic simulations, can efficiently simulate correlation phenomena such as ponderomotive squeezing and reproduces accurately cavity sideband structures on the scale of the applied quantum noise and even complicated features entirely submerged below the quantum shot noise imprecision floor. We investigate nonlinear regimes and find where comparison is possible, that the method agrees with analytical results obtained with master equations at low temperatures and in perturbative regimes.

description: In this paper we introduce the notion that artists should be able to control fluid simulations by providing examples of expected local fluid behavior (for instance, an artist might specify that magical smoke often forms star shapes). As our idea fits between high-level, global pose control and low-level parameter adjustment, we deem it mid-level control. We make our notion concrete by demonstrating two mid-level controllers providing stylized smoke effects for two-dimensional animations. With these two controllers, we allow the artist to specify both density patterns, or particle motifs, which should emerge frequently within the fluid and global texture motifs to which the fluid should conform. Each controller is responsible for constructing a stylized version of the current fluid state, which we feed-back into a global pose control method. This feedback mechanism allows the smoke to retain fluid-like behavior, while also attaining a stylized appearance suitable to integration with 2D animations. We integrate these mid-level controls with an interactive animation system, in which the user can control and keyframe all animation parameters using an interactive timeline view.

description: We analyze simulated maps of the Cosmology Large Angular Scale Surveyor (CLASS) experiment and recover a nearly cosmic-variance limited estimate of the reionization optical depth $τ$. We use a power spectrum-based likelihood to simultaneously clean foregrounds and estimate cosmological parameters in multipole space. Using software specifically designed to constrain $τ$, the amplitude of scalar fluctuations $A_s$, and the tensor-to-scalar ratio $r$, we demonstrate that the CLASS experiment will be able to estimate $τ$ within a factor of two of the full-sky cosmic variance limit allowed by cosmic microwave background polarization measurements. Additionally, we discuss the role of CLASS's $τ$ constraint in conjunction with gravitational lensing of the CMB on obtaining a $\gtrsim4σ$ measurement of the sum of the neutrino masses.

Reduction of Weak Interaction Rates in Neutron Stars by Nucleon Spin Fluctuations: Degenerate Case

Year: 1996

description: Nucleon spin fluctuations in a dense medium reduce the ``naive'' values of weak interaction rates (neutrino opacities, neutrino emissivities). We extend previous studies of this effect to the degenerate case which is appropriate for neutron stars a few ten seconds after formation. If neutron-neutron interactions by a one-pion exchange potential are the dominant cause of neutron spin fluctuations, a perturbative calculation of weak interaction rates is justified for $T\alt 3m/(4πα_π^2)\approx 1 MeV$, where $m$ is the neutron mass and $α_π\approx15$ the pion fine-structure constant. At higher temperatures, the application of Landau's theory of Fermi liquids is no longer justified, i.e. the neutrons cannot be viewed as simple quasiparticles in any obvious sense.

description: We are designing a complete autonomous legged robot to perfom planetary exploration without human supervision. This robot must traverse unknown and geographically diverse areas in order a collect samples of materials. This paper describes how a geometric terrain representation from range imagery can be used to identify footfall positions. First, we present previous research aimed to determine footfall positions. Second, we describe several methods for determining the positions for which the shape of the terrain is nearest to the shape of the foot. Third, we evaluate and compare the efficiency of these methods as functions of some parameters such as particularities of the shape of the terrain. Fourth, we introduce other methods that use thermal imaging in order to differentiate materials

Nonlinear growth of structure in cosmologies with damped matter fluctuations

description: We investigate the nonlinear evolution of structure in variants of the standard cosmological model which display damped density fluctuations relative to cold dark matter (e.g. in which cold dark matter is replaced by warm or interacting DM). Using N-body simulations, we address the question of how much information is retained from different scales in the initial linear power spectrum following the nonlinear growth of structure. We run a suite of N-body simulations with different initial linear matter power spectra to show that, once the system undergoes nonlinear evolution, the shape of the linear power spectrum at high wavenumbers does not affect the non-linear power spectrum, while it still matters for the halo mass function. Indeed, we find that linear power spectra which differ from one another only at wavenumbers larger than their half-mode wavenumber give rise to (almost) identical nonlinear power spectra at late times, regardless of the fact that they originate from different models with damped fluctuations. On the other hand, the halo mass function is more sensitive to the form of the linear power spectrum. Exploiting this result, we propose a two parameter model of the transfer function in generic damped scenarios, and show that this parametrisation works as well as the standard three parameter models for the scales on which the linear spectrum is relevant.

description: The central thesis of this article is that memory-based methods provide natural and powerful mechanisms for high-autonomy learning control. This paper takes the form of a survey of the ways in which memory-based methods can and have been applied to control tasks, with an emphasis on tasks in robotics and manufacturing. We explain the various forms that control tasks can take, and how this impacts on the choice of learning algorithm. We show a progression of five increasingly more complex algorithms which are applicable to increasingly more complex kinds of control tasks. We examine their empirical behavior on robotic and industrial tasks. The final section discusses the interesting impact that explicitly remembering all previous experiences has on the problem of learning control.
