description: A two-dimensional fluid model is used to investigate the electron heating dynamics and the production of neutral species in a capacitively coupled radio-frequency micro atmospheric pressure helium plasma jet -- specifically the COST jet -- with a small oxygen admixture. Electron heating mode transitions are found to be induced by varying the driving voltage amplitude and the O$_2$ concentration numerically and experimentally. The helium metastable density, and the charged species densities are highly relevant to the electron heating dynamics. By analyzing the creation and destruction mechanisms of the negative ions, we find that the generation of negative ions strongly depends on the O$_2$ concentration. The increase of the electronegativity with the increasing O$_2$ concentration leads to an enhancement of the bulk drift electric field. The distributions of the different neutral species densities along the direction of the gas flow inside the jet, as well as in the effluent differ a lot due to the relevant chemical reaction rates and the effect of the gas flow. The simulated results show that a fluid model can be an effective tool for qualitative investigations of micro atmospheric pressure plasma jets.

description: On 28 January 2025 from 14:30-16:00 CET, StandICT.eu hosted a webinar from the "Walk and Talk" StandICT.eu 2026 event series to present the findings of the StandICT.eu 2026 Technical Working Group (TWG) on Robotics.

This webinar presented the findings of the StandICT.eu 2026 Technical Working Group (TWG) on Robotics, which provides an updated analysis of standards for three pivotal robotics applications: guided vehicles, networked systems, and medical robotics. These areas are critical to Europe’s digital and technological transformation, with applications spanning industry, healthcare, and logistics.

Robotics plays a crucial role in achieving the European Union’s goals of innovation, sustainability, and competitiveness. However, the field faces significant standardisation gaps that must be addressed to ensure interoperability, safety, and ethical compliance across sectors. The TWG report highlights these challenges and provides actionable recommendations to align Europe’s robotics standards with its strategic priorities. The report presentation  will indeed pave the way to a broader discussion the current and future state of robotics standardisation.

Συγκεκριμένα, εξήχθησαν οι ισόθερμοι προσρόφησης Β από τρία εδάφη (αργιλοπηλώδες, αμμοαργιλοπηλώδες και αμμοπηλώδες), σε επίπεδα ηλεκτρικής αγωγιμότητας (EC) 1, 3, 6, 9 dS m-1, που καθένα από αυτά δημιουργήθηκε με διάλυμα χλωριούχου άλατος νατρίου (NaCl) ή ασβεστίου (CaCl2) ή μαγνησίου (MgCl2). Επίσης, για κάθε έδαφος αποκτήθηκε και η ισόθερμος προσρόφησης Β με απιονισμένο νερό (μάρτυρας). Στα δεδομένα προσρόφησης Β προσαρμόστηκαν οι μη γραμμικές εξισώσεις Langmuir και Freundlich με την τεχνική της μη ευθύγραμμης συμμεταβολής. Τα αποτελέσματα έδειξαν ότι η σταθερά Μ (μέγιστο προσρόφησης Β) της Langmuir αυξήθηκε σημαντικά, στο αμμοαργιλοπηλώδες έδαφος, σε όλα τα επίπεδα ΕC με όλα τα άλατα σε σχέση με τον μάρτυρα. Παρόμοια αποτελέσματα αποκτήθηκαν και για τα άλλα δύο εδάφη, μόνο στην περίπτωση του MgCl2. Όσον αφορά την εξίσωση Freundlich, η σταθερά k (προσροφημένο Β για C = 1) αυξήθηκε σημαντικά, στο αργιλοπηλώδες έδαφος, σε όλα τα επίπεδα ΕC με όλα τα άλατα σε σύγκριση με τον μάρτυρα. Επομένως, η κοκκομετρική σύσταση του εδάφους μπορεί να μεταβάλλει την επίδραση της αλατότητας στην προσρόφηση Β. Όσον αφορά το είδος του κατιόντος, το Mg2+ φαίνεται να αυξάνει την μέγιστη χωρητικότητα του εδάφους για Β, ανεξαρτήτως του τύπου του
description: The aim of this study was to determine the effect of salinity and cation species in irrigation water or soil solution on boron (B) adsorption by almost neutral soils with different texture. Specifically, Β adsorption isotherms were obtained for three soils (clay loam, sandy clay loam, sandy loam), at electrical conductivity levels (EC) of 1, 3, 6, 9 dS m-1, each of which was established using solution of chlorate salt of sodium (NaCl) or calcium (CaCl2) or magnesium (MgCl2). In addition, for each soil, B adsorption isotherm with deionized water was obtained (control). The nonlinear Langmuir and Freundlich equations were fitted to the adsorption data, employing nonlinear regression. Results showed that the Langmuir M (B adsorption maximum) significantly increased, in the sandy clay loam soil, at all EC levels with all salts compared with the control. Similar results were obtained for the other two soils only in the case of ΜgCl2. As far as the Freundlich equation is concerned, the constant k (adsorbed Β for C = 1) significantly increased, in the clay loam soil, at all EC levels with all salts in comparison to control. These results suggest that soil texture may influence the salinity effect on B adsorption by soil. As far as the cations are concerned, Μg2+ seems to enhance maximum adsorption capacity of soil for B, irrespectively of its type
Interactive flow field modeling for the design and control of fluid motion in computer animation

Publisher: name: University of British Columbia

description: Ubiquitous and captivating, fluid—gaseous and liquid—motion is often desired in computer animation. For example, rives, lakes, and clouds enhance flights simulations. Realizing realistic fluid behaviour, however, can be difficult and laborious using traditional computer animation methods. Ad hoc kinematic models of fluid motion have been presented to facilitate the animation of fluids, but it is not clear how to extend or integrate these models to describe more general fluid motion. Simple dynamic models have been presented, but it is difficult to control the dynamic simulation to achieve the desired effect. To address this problem, a simple, hydrodynamically-based framework for realistically integrating models of fluid flow for computer animation purposes is presented. This framework is based on the continuity equation for incompressible flow, and allows flow fields to be linearly combined, regardless of whether they are interactively modeled or computed by dynamic simulation. Novel interactive flow field modeling methods are introduced to allow the animator to manipulate spline curves that correspond to streamlines in the flow field. The spline-based flow fields can be computed at interactive speed on standard graphics workstations. Many dynamic simulations produce flow fields that satisfy the continuity equation, and these can be linearly combined with the modeled flow field to define a mean flow field which is sampled at the nodes of a lattice. Turbulence is modeled by advecting stochastic distributions of models of vortex flow with the mean flow, allowing infinite resolution for small-scale complexity. Geometric models are advected using the final resulting flow field. A simple animation system incorporating the interactive flow modeling methods was implemented and shows this approach to be a promising and easily extendable method of realistically animating fluids.

description: The paper presents some solutions to the five dimensional Einstein equations due to a perfect fluid on the brane with pure dust filling the entire bulk in one case and a cosmological constant (or vacuum) in the bulk for the second case. In the first case, there is a linear relationship between isotropic pressure, energy density and the brane tension, while in the second case, the perfect fluid is assumed to be in the form of chaplygin gas. Cosmological solutions are found both for brane and bulk scenarios and some interesting features are obtained for the chaplygin gas on the brane which are distinctly different from the standard cosmology in four dimensions.

description: The Cayley-Klein (CK) formalism is applied to the real algebra ${so}(5)$ by making use of four graded contraction parameters describing in a unified setting 81 Lie algebras, which cover the (anti-)de Sitter, Poincaré, Newtonian and Carrollian algebras. Starting with the Drinfel'd-Jimbo real Lie bialgebra for ${so}(5)$ together with its Drinfel'd double structure, we obtain the corresponding CK bialgebra and the CK $r$-matrix coming from a Drinfel'd double. As a novelty, we construct the (first-order) noncommutative CK spaces of points, lines, 2-planes and 3-hyperplanes, studying their structural properties. By requiring to deal with real structures, it comes out that there exist 63 specific real Lie bialgebras together with their sets of four noncommutative spaces. Furthermore, we find 14 classical $r$-matrices coming from Drinfel'd doubles, obtaining new results for the de Sitter ${so}(4,1)$ and anti-de Sitter ${so}(3,2)$ and for some of their contractions. These geometric results are exhaustively applied onto the (3+1)D kinematical algebras, not only considering the usual (3+1)D spacetime but also the 6D space of lines. We establish different assignations between the geometrical CK generators and the kinematical ones which convey physical identifications for the CK contraction parameters in terms of the cosmological constant/curvature $Λ$ and speed of light $c$. We finally obtain four classes of kinematical $r$-matrices together with their noncommutative spacetimes and spaces of lines, comprising all $κ$-deformations as particular cases.

description: We study the characterization and realization of higher-order topological Anderson insulator (HOTAI) in non-Hermitian systems, where the non-Hermitian mechanism ensures extra symmetries as well as gain and loss disorder.We illuminate that the quadrupole moment $Q_{xy}$ can be used as the real space topological invariant of non-Hermitian higher-order topological insulator (HOTI). Based on the biorthogonal bases and non-Hermitian symmetries, we prove that $Q_{xy}$ can be quantized to $0$ or $0.5$. Considering the disorder effect, we find the disorder-induced phase transition from normal insulator to non-Hermitian HOTAI. Furthermore, we elucidate that the real space topological invariant $Q_{xy}$ is also applicable for systems with the non-Hermitian skin effect. Our work enlightens the study of the combination of disorder and non-Hermitian HOTI.

description: In this present job, first we examine the consequences of the Industrial Revolution in England and the causes of the French Revolution. Then we proceed to the causes of the birth of a new political power, socialism. The ideas of Rousseau, Voltaire and Diderot are those who were the occasion to lay the foundations on which the three precursors of Utopian socialism will build an entire empire. An empire looked to equality, freedom and ownership. We referred to the personalities of the first representative of Saint Simon, Charles Fourier and Robert Owen. Finally, we attempt an approach to the basic principles of utopian Socialism. The spirit an the methodology followed referred to the close relationship between political philosophy, political science in connection with the facts in themselves that are recorded as a political history. We Start from a brief reference/introduction to prevailing social, economic conditions as well as the recruitment of proto-socialism as a theory and political practice
The boxer

description: The Boxer is a novella that pits metaphysics against New Age shallowness. It weaves together the surreal comedy of Flann O'Brien’s The Third Policeman with Faulknerian stream of consciousness all set atop highly Westernized ‘60s mysticism in the style of Alan Watts.While on the job, Heather, a Starbucks Barista, witnesses the aftermath of an accidental death and enters into a period of private mourning. As the spiritual bankruptcy of her current condition fails to offer her guidance, she experiences a psychological break and encounters her own subconscious, which torments her in the form of a seemingly meaningless green box. Her sanity dwindles, forcing her to reevaluate her relationships, goals, and sense of self.The story is told in a close third-person point of view, granting access to Heather’s consciousness without relying upon the monologuing style common to texts such as As I Lay Dying. This, when paired with affectionate nods towards ‘60s nostalgia and New Age imagery, attempts to critique the modern American landscape as one of plastic spirituality without departing too far from the central character’s voice or sense of humor.

description: World grain stocks rapidly declined from record high levels in 1986. By late 1989, the world's carryover stocks-to-use ratio approached historic lows. But this decline is expected to be temporary. Stocks in most countries tend not to be available for use outside the country. Consequently the United States holds the bulk of the world grain market's residual supply of stocks. Grain stock levels and locations around the world could be heavily influenced by farm policy decisions made in the United States and international trade negotiations.

description: We present observations of the stellar kinematics of the centre of the core collapsed globular cluster M15 obtained with the MUSE integral field spectrograph on the VLT operating in narrow field mode. Thanks to the use of adaptive optics, we obtain a spatial resolution of 0.1arcsec and are able to reliably measure the radial velocities of 864 stars within 8 arcsec of the centre of M15 thus providing the largest sample of radial velocities ever obtained for the innermost regions of this system. Combined with previous observations of M15 using MUSE in wide field mode and literature data, we find that the central kinematics of M15 are complex with the rotation axis of the core of M15 offset from the rotation axis of the bulk of the cluster. While this complexity has been suggested by previous work, we confirm it at higher significance and in more detail.

Interactions of Ions and Ultracold Neutral Atom Ensembles in Composite Optical Dipole Traps: Developments and Perspectives

Year: 2021
Subjects: subject: Atomic Physics (physics.atom-ph)

description: Ion-atom interactions are a comparatively recent field of research that has drawn considerable attention due to its applications in areas including quantum chemistry and quantum simulations. In first experiments, atomic ions and neutral atoms have been successfully overlapped by devising hybrid apparatuses combining established trapping methods, Paul traps for ions and optical or magneto-optical traps for neutral atoms, respectively. Since then, the field has seen considerable progress, but the inherent presence of radiofrequency (rf) fields in such hybrid traps was found to have a limiting impact on the achievable collision energies. Recently, it was shown that suitable combinations of optical dipole traps (ODTs) can be used for trapping both atoms and atomic ions alike, allowing to carry out experiments in absence of any rf fields. Here, we show that the expected cooling in such bichromatic traps is highly sensitive to relative position fluctuations between the two optical trapping beams, suggesting that this is the dominant mechanism limiting the currently observed cooling performance. We discuss strategies for mitigating these effects by using optimized setups featuring adapted ODT configurations. This includes proposed schemes that may mitigate three-body losses expected at very low temperatures, allowing to access the quantum dominated regime of interaction.

description: The decade-long Vista Variables in the Via Lactea (VVV) survey has detected numerous highly variable young stellar objects (YSOs). We present a study of 61 highly variable VVV YSOs combining near-infrared spectra from Magellan and VLT with VVV and NEOWISE light curves to investigate the physical mechanisms behind eruptive events. Most sources are spectroscopically confirmed as eruptive variables (typically Class I YSOs) but variable extinction is also seen. Among them, magnetically controlled accretion, identified by HI recombination emission, is observed in 47 YSOs. Boundary layer accretion, associated with FU Ori-like outbursts identified by CO overtone and H2O absorption, is observed only in longer duration events (> 5 yr total duration). However, even in long-duration events, the magnetically controlled accretion mode predominates, with amplitudes similar to the boundary layer mode. We find that the ratio of amplitudes in Ks and W2 can distinguish between variable accretion and variable extinction. 13 YSOs are periodic or quasi-periodic variables. We identify examples of periodic accretors and extinction-driven periodicity among them (with periods up to 5 yr) though more data are needed to classify some cases. The data suggest that dynamic interactions with a companion may control the accretion rate in a substantial proportion of eruptive systems.
Selection and organization of subjective contours
Creators: name: Ando, Yoko
Publisher: name: University of British Columbia
Year: 2009

description: Subjective contours are physically invisible borders drawn on certain images that can nevertheless be seen by humans. This is because the human vision system makes assumptions on the occlusion of objects. The study of subjective contours is important for helping us understand more about the human visual perception. The purpose of this thesis is to understand the perception of subjective contours and to detect subjective contours by computer. The previous subjective contour detection systems limit the subjective contours they can detect by restricting the locations on the figures where the subjective contours can be seen and by using the consistent subjective surface orientation. In this thesis, we consider the overall organization of subjective contours. We do not put the restriction on the subjective surface orientation because we view the subjective contour as a boundary separating the two regions locally. A model for subjective contour detection is presented based on four criteria: no prior knowledge is necessary to detect a subjective contour; a subjective contour is a special type of occluding contour; the shape of a subjective contour is determined by the viewing condition; and it is possible to have many subjective contour organizations from one image. The rules for subjective contour organization are described and the model explains different types of subjective contour organizations. There are three stages in the computer implementation of subjective contour detection. The first stage is preprocessing of figures where the real contours are segmented according to their curvature discontinuities by Lowe's curve partition method. The next stage is local processing in which each real contour segment selects all the potential subjective contours and their connecting real contour segments. The final stage is global processing to organize the real and subjective contours which can be seen at the same time. Many subjective contour images are tested and good results are produced.

Ο έλεγχος αυτός υπήρξε πολυδιάστατος, σύμφωνος με τις ανάγκες της πόλης, και ήταν τόσο οικονομικός, όσο και αστυνομικός, χωροταξικός, αλλά και στρατιωτικός. Λόγω έλλειψης πηγών για την συντριπτική πλειονότητα των πόλεων, η έρευνα περιορίστηκε στις πόλεις για τις οποίες υπάρχει το ανάλογο υλικό, αν και οι τελευταίες δεν είναι περιορισμένες γεωγραφικά, αλλά διάσπαρτες σε όλη τη λεκάνη της Μεσογείου. Αντίθετα, για όσο μας βοηθούν οι διασωθείσες πηγές, δεν υπάρχουν χρονολογικά όρια, πέραν αυτών της αρχαίας ιστορίας.

Τέλος, προσπαθήσαμε να εξάγουμε κάποια βασικά συμπεράσματα και όσο ήταν δυνατό να σχηματίσουμε μια γενική εικόνα για τους θεσμούς αυτούς και τον ρόλο που έπαιξαν στη λειτουργία των πόλεων
description: The aim of the present thesis was the study of the institutions and the offices the ancient Greek cities created to control and supervise their harbors and seaports. This control was multidimensional, according to the cities’ needs, and it was economical, land planning and aimed to maintain order and military security. Due to lack of primary sources for the vast majority of the cities, the research is limited to the cities for which we have sources available. On the contrary, these cities are not limited in a small geographical area, but are scattered across the Mediterranean. Additionally, there are no chronological limits in this research. Furthermore, we examined the terminology used by these cities for their institutions and offices and we analyzed their tasks and aims. Finally, we tried to draw a conclusion and, if possible, to form a general idea about the nature of these institutions and the part they played in the ancient Greek city’s functioning

description: Το Αξίωμα της Επιλογής (AC) αποτελεί αδιαμφισβήτητα ένα από τα πιο συζητημένα αξιώματα στην ιστορία των μαθηματικών, λόγω της μη κατασκευαστικής του φύσης. Αν και πλέον είναι αποδεκτό από τους περισσότερους μαθηματικούς, το AC εξακολουθεί να εγείρει το ενδιαφέρον κυρίως λόγω των ισοδύναμων προτάσεων σε όλο το φάσμα των μαθηματικών, είτε με το AC είτε με κάποια γνήσια ασθενέστερη μορφή του. Στην εργασία αυτή μελετάμε κάποιες από τις καταστροφές που προκύπτουν στη Θεωρία Γράφων χωρίς τη χρήση του AC, στη ZF Θεωρία Συνόλων. Αρχικά, παρουσιάζουμε το κλασσικό αποτέλεσμα των Höft και Howard (Κάθε συνεκτικός γράφος περιέχει ένα παράγον δένδρο είναι ισοδύναμο με το AC) καθώς και το ότι η ύπαρξη του χρωματικού αριθμού ενός γράφου είναι ισοδύναμη με το AC. Στη συνέχεια, παρουσιάζουμε κάποια αποτελέσματα σχετικά με τις καταστροφές που προκύπτουν στους χρωματισμούς των γράφων καθώς και κάποιες κατασκευές των S. Shelah και A. Soifer οι οποίες σχετίζονται με το γνωστό πρόβλημα της συνδυαστικής, της εύρεσης χρωματικού αριθμού του επιπέδου. Τέλος, αποδεικνύουμε το Θεώρημα του M. Hall σχετικά με την χαλάρωση των υποθέσεων του Θεωρήματος του Γάμου (με χρήση του Θεωρήματος του Πρώτου Ιδεώδους) και κάνουμε την αντίστοιχη σύνδεση με τα ταιριάσματα διμερών γραφημάτων
description: The Axiom of Choice (AC) is undoubtedly one of the most discussed axioms in the history of mathematics due to its non constructive nature. Although nowdays AC is accepted and used by most mathematicians, it still raises interest mainly due to the fact that many important theorems in pure mathematics are equivalent to AC or to some strictly weaker form of AC. In this thesis we study some of the disasters in graph theory in ZF, without the AC. We present the typical result of H. Höft and P. Howard (Every connected tree has a spanning tree that is equivalent to AC) and also that the existence of the chromatic number of a graph is equivalent to AC. We also study disasters in graph colorings and some recent results due to S. Shelah and A. Soifer that are related to the chromatic number of the plane. Finally, we prove a generalized version (result of M. Hall) of P. Hall's marriage theorem (using the Boolean Prime Ideal Theorem) that is connected to bipartite matching theory

description: H Ιρλανδία μπορεί να χαρακτηρισθεί ως μια "νησιωτική ακαδημία", όπου πολλοί διδάχθηκαν και από όπου προήλθαν τα χριστιανικά πολιτισμικά και καλλιτεχνικά αριστουργήματα, καθώς και ένας εντυπωσιακός αριθμός αγίων. Οι μεγάλοι άγιοι, όπως ο Patrick, Abban, Columba, Finnian, Μπριγκίτα, Enda, Ciaran και πολλοί άλλοι με τη ζωή τους σε αυτό το νησί και τη χερσόνησο της Σκωτίας βοήθησαν στην εξάπλωση του Χριστιανισμού όχι μόνο σε αυτά τα εδάφη, αλλά ακόμη και μέχρι την Ολλανδία, Γαλατία, την Ελβετία, τμήμα της Γερμανίας και της βόρειας Ιταλίας. Η Ιρλανδία της εποχής εκείνης έλαβε το όνομα Νησί των Αγίων. Η δραστηριότητα του Ιρλανδικού κλήρου δεν περιοριζόταν στο έδαφος της χώρας τους, όπως βλέπουμε στους βίους των αγίων της Ιρλανδίας, αλλά ταξιδεύουν και εξερευνούν. Λέγεται ότι στην εποχή της πνευματικής άνθησης τα μοναστήρια είχαν τόσο πολλούς μοναχούς, που αναγκάζονταν να μεταβούν στην ήπειρο. Το πλήθος των εκκλησιών που χτίς τηκαν στους πρώτους αιώνες του Χριστιανισμού σε αυτά τα εδάφη υποδεικνύει την έντονη ποιμαντική δραστηριότητα των κληρικών της εποχής εκείνης
description: When Chriastianity reached Ireland in the fith century it came from different sources, from Britain and from the Continent. Both were very different from Ireland. The first recorded missionary to Ireland was Palladius, who was from Gaul. Saint Patrick was probably the most famous missionary to Ireland. It is widely believed by historians that the missions of Saint Patrick were embellished and enshrined by Patrick`s monastery at Armagh in their bid for primacy over the church in Ireland. In time, the Irish church matured and by the fourth century a number of monasteries were set up. Iona and Armagh together became the most influential monasteries in Ireland. A Celtic monastery was not of the church-and-cloisters type that appeared in the middle ages, rather, it usually consisted of an enclosure with a small stone church and a number of cells were the monks lived individually. The most prominent Irish Saints were Colum Cille, Ciaran, Brendan, Finian, Brigid, Enda, Abban and more others. They believed in people becoming "Exiles for Christ" by leaving their homes to go and live with other Christians in isolated places, thereby coming closer to God

description: Topological order characterizes those phases of matter that defy a description in terms of symmetry and cannot be distinguished in terms local order parameters. This type of order plays a key role in the theory of the fractional quantum Hall effect, as well as in topological quantum information processing. Here we show that a system of n spins forming a lattice on a Riemann surface can undergo a second order quantum phase transition between a spin-polarized phase and a string-net condensed phase. This is an example of a phase transition between magnetic and topological order. We furthermore show how to prepare the topologically ordered phase through adiabatic evolution in a time that is upper bounded by O(\sqrt{n}). This provides a physically plausible method for constructing a topological quantum memory. We discuss applications to topological and adiabatic quantum computing.

description: This research paper explores the potential impact of hate rhetoric on the frequency of hate crime events in the U.S. in the past decade. It evaluates two different styles of Presidential speech in seeking to explain the incidence of hate crimes; President Obama’s more diplomatic speech approach versus President Trump’s anti-immigrant rhetoric. The project uses volunteer-coded speech analysis, to compare hate crimes on a quarterly basis and evaluate the annual fluctuation of hate crimes against Hispanics and Latino/as . This research paper finds a suggestive relationship between hate speech occurrences and hate crime events, but due to lack of appropriate data sources, it cannot claim causation.

description: Photoelectron spectroscopy experiments in ionic solutions reveal important electronic structure information, in which the interaction between hydrated ions and water solvent can be inferred. Based on many-body perturbation theory with GW approximation, we theoretically compute the quasiparticle electronic structure of chloride anion solution, which is modeled by path-integral $ab$ $initio$ molecular dynamics simulation by taking account the nuclear quantum effects (NQEs). The electronic levels of hydrated anion as well as water are determined and compared to the recent experimental photoelectron spectra. It is found that NQEs improve the agreement between theoretical prediction and experiment because NQEs effectively weaken the hybridization of the between the $\rm Cl^-$ anion and water. Our study indicates that NQEs plays a small but non-negligible role in predicting the electronic structure of the aqueous solvation of ions of the Hofmeister series.

The performance of robot manipulation
Creators: name: Van Den Doel, Cornelis Pieter
Publisher: name: University of British Columbia
Year: 2009

description: A theory of the performance of robot manipulation is presented. The theory deals with general robotic manipulation, which is viewed as the physical interaction between a generalized manipulator and a generalized object. The generalized manipulator can be arbitrarily complex, i.e. it can consist of any number of robotic devices. Similarly, the generalized object represents the set of all the material bodies manipulated by the robot in the environment. The study of the performance of such systems is somewhat analogous to the study of the performance of algorithms and complexity theory in computer science. A digital computer produces certain desired changes in information, it transforms input into output, and complexity theory deals with the efficiency of this process. Similarly, a robotic device transforms the state of the objects it manipulates. The manipulation we are concerned with here is only different in that material objects are affected and the measure for the resources needed to perform certain tasks is not runtime or memory usage. How performance should then be measured instead is the subject of this thesis. The theory regards the manipulation as a mapping from the space of all manipulator configurations to the space of all object configurations. By endowing these manifolds with Riemannian metrics we can quantify motion in the manifolds. Performance measures, which quantify how well the robot is executing its manipulation task, arise naturally as geometrical objects associated with the mapping and the metric structure of the manifolds. Generalizations of known measures (agreeing with those previously defined for the simplest kinds of systems) arise naturally in this formalism and we construct several new types of measures. The new types of measures presented here are the effective inertia on work space, the kinematic and dynamic anisotropy measures for redundant manipulators, non-linearity measures, and redundancy measures. An extension of the theory broadens its domain of application to situations in which the relation between the robot and the object it is manipulating can not be given in explicit form, but by a set of constraint equations (possibly non-holonomic) that define it implicitly. The main contribution of this work is the theory of manipulation, which provides a theoretical foundation for robot manipulation. Computational aspects of the theory are described briefly and the theory is applied to some simple planar manipulating devices, for which several of the measures have been constructed and optimized. These applications are given here for illustrative purpose.
The roAp stars observed by the Kepler Space Telescope

description: Before the launch of the Kepler Space Telescope, most studies of the rapidly oscillating Ap (roAp) stars were conducted with ground-based photometric $B$ observations, supplemented with high-resolution time-resolved spectroscopy and some space observations with the WIRE, MOST and BRITE satellites. These modes of observation often only provided information on a single star at a time, however, Kepler provided the opportunity to observe hundreds of thousands of stars simultaneously. Over the duration of the primary 4-yr Kepler mission, and its 4-yr reconfigured K2 mission, the telescope observed at least 14 new and known roAp stars. This paper provides a summary the results of these observations, including a first look at the entire data sets, and provides a look forward to NASA's TESS mission.
