Subjects: subject: Information interfaces and presentation

subject: Proxemic interaction, control of appliances, mobile devices

description: Computing technologies continue to grow exponentially every day. However, appliances have become a class of technology that has remained stagnant through time. They are restricted by physical and cost limitations, while also aiming to provide with a lot of functionality. This leads to limited capabilities of input (through multiple buttons and combinations) and output (LEDs, small screens). This video introduces the notion of mobile proxemic awareness and control, whereby a mobile device is used as a medium to reveal of information regarding awareness of presence, state, content and control as a function of proxemics. Through the video, we explore a set of concepts that exploit different proximal distances and levels of information and controls. The video illustrates the concepts with two deliberately simple prototypes: a lamp and a radio alarm clock.

description: We are concerned with multidimensional stochastic balance laws. We identify a class of nonlinear balance laws for which uniform spatial $BV$ bounds for vanishing viscosity approximations can be achieved. Moreover, we establish temporal equicontinuity in $L^1$ of the approximations, uniformly in the viscosity coefficient. Using these estimates, we supply a multidimensional existence theory of stochastic entropy solutions. In addition, we establish an error estimate for the stochastic viscosity method, as well as an explicit estimate for the continuous dependence of stochastic entropy solutions on the flux and random source functions. Various further generalizations of the results are discussed.

description: Der vorliegende Beitrag untersucht die Erschließung mit dem öffentlichen Verkehr (ÖV) in Deutschland. Im Sinne einer nachhaltigen Mobilität sollte es unter anderem das Ziel sein, die Siedlungsentwicklung auf Flächen mit hoher ÖV-Erschließung zu konzentrieren, um so den Pkw-Verkehr zu reduzieren. Im Beitrag werden Räume nach ihrem Potenzial für den öffentlichen Nahverkehr klassifiziert und mögliche Potenziale für Transit-Oriented-Development identifiziert. Hierfür werden verschiedene, vor allem GTFS-Daten herangezogen. Die Analyse nutzt die ÖV-Güteklassen, die bereits in Österreich und der Schweiz angewendet werden. Diese kombinieren die Erschließung mit der Attraktivität des ÖV-Angebotes an einer Haltestelle. Diese Daten werden der Flächennutzung gegenübergestellt und so Potenzialflächen für Transit-Oriented-Development identifiziert. So können Räume nach ihrer Attraktivität für die ÖV-Nutzung differenziert und gezielt erschlossen werden. Es ist anzunehmen, dass durch eine entsprechende Anwendung der Methoden auch in Deutschland eine nachhaltige Flächenentwicklung unterstützt werden kann. Insgesamt bietet die Untersuchung somit wichtige Erkenntnisse für die zukünftige Gestaltung einer nachhaltigen und effizienten Mobilitätsinfrastruktur in Deutschland.

description: Ferroelectric field-effect transistors (FE-FETs) consisting of tunable dielectric layers are utilized to investigate interfacial transport processes. Large changes in the dielectric constant as a function of temperature are observed in FE-FETs in conjunction with the ferroelectric to paraelectric transition. The devices offer a test bed to evaluate specific effects of polarization on the electrical processes. FE-FETs have dominant contributions from polarization-fluctuation rather than static dipolar disorder prevalent in high k paraelectric dielectric-based FETs. Additionally, photo-excitation measurements in the depletion mode reveal clear features in the FET response at different temperatures, indicative of different transport regimes.

description: Laboratory experiments are an essential part of engineering education for students to gain practical skills and to prepare them for working in industries. However, due to the increasing number of undergraduate students and the rising cost of industry equipment, many universities are unable to provide industrial experience in the laboratories. To address these challenges, educators have proposed Virtual Laboratories (VLabs) that provide an alternative means of conducting experiments. This research proposes a specific type of VLab and investigates its significance in undergraduate engineering courses.

description: In the pursuit of establishing a sustainable space economy within the cislunar region, it is vital to formulate transfer design strategies that uncover economically viable highways between different regions of the space domain. The inherent complexity of spacecraft dynamics in the cislunar space poses challenges in determining feasible transfer options. However, the motion characterized by known dynamical structures modeled through the circular restricted three-body problem (CR3BP) aids in the identification of pathways with reasonable maneuver costs and flight times. A framework is proposed that incorporates a quasi-periodic orbit (QPOs) as an option to design transfer scenarios. This investigation focuses on the construction of transfers between periodic orbits. The framework is exemplified by the construction of pathways between an L2 9:2 synodic resonant Near-Rectilinear Halo Orbit (NRHO) and a planar Moon-centered Distant Retrograde Orbit (DRO). The innate difference in the geometries of the departure and arrival orbits of the sample case, along with the lack of natural flows towards and away from them, imply that links between these orbits may necessitate costly maneuvers. A strategy is formulated that leverages the stable and unstable manifolds associated with intermediate periodic orbits and quasi-periodic orbits to construct end-toend trajectories. As part of this strategy, a systematic methodology is outlined to streamline the determination of transfer options provided by the 5-dimensional manifolds associated with a QPO family. This approach reveals multiple local basins of solutions, both interior and exterior-types, characterized by selected intermediate orbits. The construction of transfers informed by the manifolds associated with QPOs is more intricate than those based on periodic orbits. However, QPO-derived solutions allow for the recognition of alternative local basins of solutions and often offer more cost-effective transfer options when compared to trajectories designed using periodic orbits that underlie the QPOs.

description: We study the origin of attracting phenomena in the ray dynamics of coupled optical microcavities. To this end we investigate a combined map that is composed of standard and linear map, and a selection rule that defines when which map has to be used. We find that this system shows attracting dynamics, leading exactly to a quasiattractor, due to collapse of phase space. For coupled dielectric disks, we derive the corresponding mapping based on a ray model with deterministic selection rule and study the quasiattractor obtained from it. We also discuss a generalized Poincaré surface of section at dielectric interfaces.

description: We report a new detection of the H-band thermal emission of CoRoT-1b and two confirmation detections of the Ks-band thermal emission of WASP-12b at secondary eclipses. The H-band measurement of CoRoT-1b shows an eclipse depth of 0.145%\pm0.049% with a 3-σ percentile between 0.033% - 0.235%. This depth is consistent with the previous conclusions that the planet has an isother- mal region with inefficient heat transport from dayside to nightside, and has a dayside thermal inversion layer at high altitude. The two Ks band detections of WASP-12b show a joint eclipse depth of 0.299%\pm0.065%. This result agrees with the measurement of Croll & collaborators, providing independent confirmation of their measurement. The repeatability of the WASP-12b measurements also validates our data analysis method. Our measurements, in addition to a number of previous results made with other telescopes, demonstrate that ground-based observations are becoming widely available for characterization of atmospheres of hot Jupiters.

Year: 2011

description: Real-time search methods are suited for tasks in which the agent is interacting with an initially unknown environment in real time. In such simultaneous planning and learning problems, the agent has to select its actions in a limited amount of time, while sensing only a local part of the environment centered at the agents current location. Real-time heuristic search agents select actions using a limited lookahead search and evaluating the frontier states with a heuristic function. Over repeated experiences, they refine heuristic values of states to avoid infinite loops and to converge to better solutions. The wide spread of such settings in autonomous software and hardware agents has led to an explosion of real-time search algorithms over the last two decades. Not only is a potential user confronted with a hodgepodge of algorithms, but he also faces the choice of control parameters they use. In this paper we address both problems. The first contribution is an introduction of a simple three-parameter framework (named LRTS) which extracts the core ideas behind many existing algorithms. We then prove that LRTA*, epsilon-LRTA*, SLA*, and gamma-Trap algorithms are special cases of our framework. Thus, they are unified and extended with additional features. Second, we prove completeness and convergence of any algorithm covered by the LRTS framework. Third, we prove several upper-bounds relating the control parameters and solution quality. Finally, we analyze the influence of the three control parameters empirically in the realistic scalable domains of real-time navigation on initially unknown maps from a commercial role-playing game as well as routing in ad hoc sensor networks.

description: Using scanning micro X-ray diffraction we report a mixed real and reciprocal space visualization of the spatial heterogeneity of the lattice incommensurate supermodulation in single crystal of Bi2Sr2CaCu2O8+y with Tc=84 K. The mapping shows an amplitude distribution of the supermodulation with large lattice fluctuations at microscale with about 50% amplitude variation. The angular distribution of the supermodulation amplitude in the a-b plane shows a lattice chiral symmetry, forming a left-handed oriented striped pattern. The spatial correlation of the supermodulation is well described by a compressed exponential with an exponent of 1.5 and a correlation length of about 50 μm, showing the intrinsic lattice disorder in high temperature superconductors.

Extended Minds and Instrumentality
Creators: name: Asbaeck, Julian
Publisher: name: On_Culture
Year: 2023

description: This contribution offers a literary approach to extended cognition and asks in which capacity interactions with the nonhuman come to shape cognitive development. Specifically, this question is posed in regards to our active use of nonhuman instruments that are recognized as a reflection of social practices that mediate our engagement with the world. In this sense, the fictional journal entries of this _perspective track the development of novel cognitive structures on the basis of a recently introduced communication device. The narration provides a genealogy of a communal shift in thought and in conclusion advances speculations on the mediating role of instruments. In continuation, the narrative segment is followed by a scholarly reflection which decidedly rejects the idea of cognition as limited to the confines of the head. Through elaborating the hybrid alliances between ourselves and the nonhuman, this second segment mobilizes concerns of the extended mind hypothesis in the context of artificial intelligence. This succinct reflection hence applies questions regarding the mediating role of instruments to the domain of artificial intelligence and asks how computational architectures which actively adapt to our behavioral patterns modify the way in which the instrument relation ought to be critically assessed.

description: Damit Österreich das Ziel "Klimaneutralität 2040" im Güterverkehr erreicht, ist rascher Handlungsbedarf gegeben. Der Straßengüterverkehr verursacht etwa ein Drittel der Treibhausgasemissionen des Sektors Verkehr und etwa 11 Prozent der nationalen Treibhausgasemission. Ohne die breite Markteinführung von Fahrzeugen mit alternativen Antrieben ist ein klimaverträglicher Güterverkehr außer Reichweite. Das ist vor allem im Hinblick auf die langen Verweilzeiten von neu zugelassenen Lkw im Gesamtbestand sowie die lange Projektdauer beim Aufbau von Infrastruktur notwendig. Eine rechtzeitige Transformation wird nur gelingen, wenn Logistiker, Energieversorger, Netzbetreiber und Fahrzeughersteller mit voller Entschlossenheit gemeinsam an Lösungen arbeiten.

description: This work proposes the concept of shared presence, where we enable a user to “become” a co-located humanoid robot while still being able to use their real body to complete tasks. The user controls the robot and sees with its vision and sen-sors, while still maintaining awareness and use of their real body for tasks other than controlling the robot. This shared presence can be used to accomplish tasks that are difficult for one person alone, for example, a robot manipulating a circuit board for easier soldering by the user, lifting and manipulat-ing heavy or unwieldy objects together, or generally having the robot conduct and complete secondary tasks while the user focuses on the primary tasks. If people are able to over-come the cognitive difficulty of maintaining presence for both themselves and a nearby remote entity, tasks that typi-cally require the use of two people could simply require one person assisted by a humanoid robot that they control. In this work, we explore some of the challenges of creating such a system, propose research questions for shared presence, and present our initial implementation that can enable shared presence. We believe shared presence opens up a new re-search direction that can be applied to many fields, including manufacturing, home-assistant robotics, and education

description: We present the 1.9--4.2um spectra of the five bright (L<11.2) young stars associated with silhouette disks with moderate to high inclination angle of 39--80deg in the M42 and M43 regions. The water ice absorption is seen toward d121-1925 and d216-0939, while the spectra of d182-316, d183-405, and d218-354 show no water ice feature around 3.1um within the detection limits. By comparing the water ice features toward nearby stars, we find that the water ice absorption toward d121-1925 and d216-0939 most likely originates from the foreground material and the surrounding disk, respectively. The angle of the disk inclination is found to be mainly responsible for the difference of the optical depth of the water ice among the five young stars. Our results suggest that there is a critical inclination angle between 65deg and 75deg for the circumstellar disk where the water ice absorption becomes strong. The average density at the disk surface of d216-0939 was found to be 6.38x10^(-18) g cm^(-3). The water ice absorption band in the d216-0939 disk is remarkable in that the maximum optical depth of the water ice band is at a longer wavelength than detected before. It indicates that the primary carrier of the feature is purely crystallized water ice at the surface of the d216-0939 disk with characteristic size of ~0.8um, which suggests grain growth. This is the first direct detection of purely crystallized water ice in a silhouette disk.

description: Text clustering is a way to organize unstructured text data by identifying groups within a set of documents. Government agencies use text clustering for a variety of problems, such as qualitative coding of open-text survey responses. Once clusters are generated, they must be named and described to be useful. This often involves manual review by subject matter experts, which is costly and slow.

The tool visualizes at four different levels, starting from the conversation level down to the message level, the word level and finally the character level. The tool provides means to visualize the typing speed and rhythms of an arbitrary number of conversers. Additionally, it attempts to visualize intangible characteristic of a typed message such as hesitance (uncertainty) and emphasis. ChatVis allows for mouse as well as keyboard interactions to give the user a variety of filtering and zooming options. The system state is always saved allowing for animation through temporal aspects of the conversation. Moreover, the conversation can be persisted to XML and loaded back on demand for comparison purposes amongst different people.

description: In the presence of cosmic chiral asymmetry, chiral-vorticity and chiral-magnetic effects can play an important role in the generation and evolution of magnetic fields in the early universe. We include these chiral effects in the magnetic field equations and find solutions under simplifying assumptions. Our numerical and analytical results show the presence of an attractor solution in which chiral effects produce a strong, narrow, Gaussian peak in the magnetic spectrum and the magnetic field becomes maximally helical. The peak in the spectrum shifts to longer length scales and becomes sharper with evolution. We also find that the dynamics may become non-linear for certain parameters, pointing to the necessity of a more complete analysis.

description: Die anthropogene Aufhellung des nächtlichen Himmels durch künstliche Beleuchtung nimmt kontinuierlich zu. Künstliche Beleuchtung illuminiert Flächen, auch wenn keine Notwendigkeit besteht. Dieses Phänomen wird als Lichtverschmutzung bezeichnet. Dabei überlagert anthropogene Beleuchtung nicht nur das natürliche Licht, sie hat auch negative Folgen für Fauna und Flora – zudem werden jüngst negative Auswirkungen auf den Menschen deutlicher. Ebenso erweisen sich die Folgeerscheinungen der Lichtverschmutzung für Städte und Kommunen als ein nicht zu vernachlässigendes Problem. Durch Beleuchtung wird Licht emittiert – doch wo kommt es an, und welche Bedeutung hat es für den Raum? Ineffiziente Lichtquellen abzuschalten ist keine Option. Es bedarf einer informellen Lösung und einer innovativen Steuerung des Lichtbedarfs. Durch den Schutz natürlicher Nachtlandschaften werden Nebeneffekte erzielt, da nicht nur Energie, sondern auch monetäre Mittel eingespart werden. Beim Versuch einer Einordnung von Sternenparks als informelles und kommunales Steuerungselement für den Natur- und Freiraumschutz lässt sich die Klimapolitik/- und Umweltschutzdebatte anführen. In diesem Zusammenhang wird der Lichtverschmutzung keine entscheidende Rolle zugesprochen. Jedoch können Verbindungen hergestellt werden. Sternenparks können, in ihrer Funktion zum Schutz der natürlichen Nachtlandschaften, einen erheblichen Beitrag leisten. Hierbei werden Sternenparks empirisch untersucht und durch eine Analyse miteinander verglichen. Dies soll Aufschluss darüber geben, ob Sternenparks als informelles und kommunales Steuerungselement für den Natur- und Freiraumschutz anzusehen sind. Es wird betrachtet, inwieweit die Projekte der Sternenparks in Bezug zu Lichtverschmutzung bzw. Natur- und Freiraumschutz angewandt werden und welche Planungskultur darüber hinaus verfolgt wird. Dies soll einen Beitrag zur informellen Regionalentwicklung liefern und Impulsgeber für einen Informationsaustausch sein. Das Format „Sternenparks“ wird als Basis für eine nachhaltige Formel der ökologisch-ökonomisch orientierten Beleuchtungskultur herangezogen. Ebenso soll mit einer zielgerichteten Analyse untersucht werden, wie Regionen dieses informelle Instrument für Naturschutzbelange und freiraumschützende Maßnahmen anwenden, um beispielsweise öffentliche Straßenbeleuchtung ökologisch und vor allem auch ökonomisch umzurüsten.
Effect of particle fabric on the one-dimensional compression response of Fraser River sand
Creators: name: Northcutt, Sheri Lynn
Publisher: name: University of British Columbia
Year: 2010

description: One-dimensional compression of sand with lateral stress measurement allows for laboratory determination of the coefficient of lateral pressure at rest, Ko. Commonly used to define the initial state of stress in soil where no lateral strain occurs, Ko is calculated as the ratio of horizontal to vertical effective stress. The present study aims to investigate the role of initial particle fabric in one-dimensional compression and to determine the effect of fabric on the coefficient of lateral pressure at rest in Fraser River sand. One-dimensional compression with lateral stress measurement was carried out on reconstituted Fraser River sand specimens using an instrumented oedometer. Laboratory specimen reconstitution methods were developed in order to construct different particle fabrics. Three different techniques were utilized: air pluviation, tamping and vibration. In addition, the effects of initial relative density and loading history on the compression response were evaluated. Each one-dimensional compression test was executed in three distinct phases: virgin loading, unloading and reloading. The key results from the testing program were compared with current methods available for estimation of Ko. The results from the present study show that specimens resulting from different laboratory reconstitution methods (i.e., initial particle fabrics) exhibit different one-dimensional compression responses. For Fraser River sand in one-dimensional compression, air-pluviated specimens yield the highest Ko values, tamped specimens produce the lowest Ko values and vibrated specimens rank intermediate. With increasing initial relative density, regardless of the initial specimen preparation method, the measured Ko values generally decrease. Upon reloading, measured Ko values are slightly reduced from those observed during virgin loading. Furthermore, results from the present study indicate that the current methods commonly used for determination of Ko do not necessarily provide suitable estimations for variable granular particle fabrics arising from different specimen reconstitution techniques. A new method for determination of Ko is proposed, as a function of the constant-volume friction angle, initial relative density and a factor accounting for the initial particle fabric.

description: We derive an exact, continuous-variable path integral (PI) representation of the canonical partition function for electronically nonadiabatic systems. Utilizing the Stock-Thoss (ST) mapping for an N-level system, matrix elements of the Boltzmann operator are expressed in Cartesian coordinates for both the nuclear and electronic degrees of freedom. The PI discretization presented here properly constrains the electronic Cartesian coordinates to the physical subspace of the mapping. We numerically demonstrate that the resulting PI-ST representation is exact for the calculation of equilibrium properties of systems with coupled electronic and nuclear degrees of freedom. We further show that the PI-ST formulation provides a natural means to initialize semiclassical trajectories for the calculation of real-time thermal correlation functions, which is numerically demonstrated in applications to a series of nonadiabatic model systems.

description: The significance of cybersecurity methods, strategies, and programs in protecting computers and electronic devices is crucial throughout the technological infrastructure. Despite the considerable growth in the cybersecurity field and its expansive workforce, there exists a notable underrepresentation, specifically among Black/African American females. This study examines the barriers hindering the inclusion of Black women in the cybersecurity workforce such as socioeconomic factors, limited educational access, biases, and workplace culture. The urgency of addressing these challenges calls for solutions such as education programs, mentorship initiatives, creating inclusive workplace environments, and promoting advocacy and increased awareness within the cybersecurity field. Additionally, this paper also features insightful interviews with successful Black female cybersecurity professionals, providing real-world perspectives and valuable advice. While strides have been made in acknowledging obstacles and implementing solutions, the representation gap for Black/African American women in cybersecurity persists, underscoring the need for further research in this area. Ultimately, this study encourages collaborative efforts to dismantle barriers and foster inclusivity, ensuring a more diverse and innovative cybersecurity sector.

description: Innovative Methoden der künstlichen Intelligenz werden eingesetzt, um mittels Luftbildaufnahmen und unterschiedlicher, frei verfügbarer Geodaten jeden Gleisanschluss auf Flächen in gewerblicher Bodennutzung des Bundesgebiets zu identifizieren und so eine Datenbasis für Infrastruktur-/ Standortfragen zu bilden. Standorte werden hinsichtlich ihrer Ansiedlungsattraktivität gestärkt und die Verlagerung von Güterverkehr auf die Schiene wird gefördert. Die wesentliche Tätigkeit des Forschungsprojekts umfasst die Entwicklung einer automatischen Prozessierungskette (unter Anwendung von Methoden der Mustererkennung mittels neuronaler Netze) zur flächendeckenden Identifikation nicht registrierter Gleisanschlüsse. Hierzu werden Lern- und Testdaten erzeugt, unbekannte Gleisanschlüsse identifiziert, sowie eine Ergebnisüberprüfung und
 -kommunikation erarbeitet. Ziel ist es, ein drängendes Bedürfnis des Schienengüterverkehrs und der verladenden Unternehmen zu erfüllen: Anschluss an das Schienennetz. Hierzu werden KI-gestützte Bilderkennungsverfahren für die Anwendung in der Schieneninfrastruktur und der Unternehmensansiedlung adaptiert und optimiert. Das Ergebnis ist eine Kartierung und ein Verständnis über die bundesweite Verteilung von privaten Gleisanschlüssen . Neben der Einzelinformation werden auch aggregierte Karten für Gewerbegebiete und höherer Ebenen angefertigt. Die Ergebnisse werden in Tabellen- und interaktiver, digitaler Kartenform bereitgestellt, was eine hohe Anschlussfähigkeit garantiert. Teil des Projekts ist die Erarbeitung einer Kommunikationsstrategie. So wird u. a. über die verschiedenen Kommunikationskanäle von Partnern und des Beirats ein langfristiger und freier Zugang für jede Interessensgruppe sichergestellt. Die Verwertbarkeit in der Praxis ergibt sich durch die frühzeitige Einbindung von Nutzervertretern.

We find the supertube Hamiltonian in these backgrounds and show that there exist metastable supertube configurations, that can decay into supersymmetric and non-supersymmetric ones via brane-flux annihilation. We also find stable non-supersymmetric configurations. Both the metastable and the stable non-supersymmetric configuration are expected to describe microstate geometries for non-extremal black holes, and we discuss the implication of their existence for the fuzzball proposal.

description: Digitale Lösungen beim Umgang mit Geodaten in den öffentlichen Verwaltungen sind schon heute kaum noch wegzudenken. Aktuelle Forschungsergebnisse aus qualitativen und quantitativen Befragungen im Rahmen des Forschungsprojekts SARDINE (Universität Leipzig, InfAI Leipzig, HTWK Leipzig) zeigen, dass digitale Geodaten abseits der „klassischen“ Raum- und Stadtplanungsprozesse absehbar in viele Fachprozesse Einzug halten werden. Dabei stellt das Handeln der öffentlichen Verwaltung besondere Anforderungen an die technischen Lösungen hinsichtlich Interoperabilität, Sicherheit und Archivierungsfähigkeit. Die aktuellen empirischen Ergebnisse, die auf einer qualitativen Studie (Expert:innenbefragung) und auf einer quantitativen Studie (Befragung von Vertreter:innen von Landes- und Kommunalverwaltungen im Freistaat Sachsen) beruhen, bieten breite und tiefe Einblicke in die Nutzungspotenziale, aber auch in die Hindernisse für eine noch intensivere Nutzung und Vernetzung digitaler Geodaten in der öffentlichen Verwaltung. Ein bedeutsames Themenfeld stellen etwa Standards dar, deren Fehlen die ämterübergreifende Nutzung behindert. Ebenso ist erkennbar, dass sowohl technische als auch verwaltungsorganisatorische Hinderungsgründe bestehen, was die Wirksamkeit einseitiger technischer Lösungen begrenzt. Im Vortrag werden die Befragungsergebnisse vorgestellt, mit weiteren aktuellen Entwicklungen abgeglichen (z. B. OZG-Verlegung) und eine Systematik vorgestellt, wie eine intensivere und effizientere Nutzung digitaler Geodaten in der öffentlichen Verwaltung befördert werden kann. Daraus leiten sich Politikempfehlungen ab, die kurz vorgestellt werden.

description: Abstact: We introduce new models of energy redistribution in stochastic chemical kinetics with several molecule types and energy parameters. The main results concern the situations when there are product form measures. Using a probabilistic interpretation of the related Boltzmann equation, we find some invariant measures explicitly and prove convergence to them.

description: In this paper, we present results from a qualitative empirical study of collocated group console gaming. We focus on motivations for, perceptions of, and practices surrounding the shared use of console games by a variety of established groups of gamers. These groups include both intragenerational groups of youth, adults, and elders as well as intergenerational families. Our analysis highlights the numerous ways in which console games serve as a computational meeting place for a diverse population of gamers.
Motivating Sustainable Energy Consumption in the Home
Creators: name: He, Helen Ai

Year: 2008
Subjects: subject: sustainable living
subject: energy consumption
subject: Sustainable living, energy consumption, behaviour change

description: Technologies are just now being developed that encourage sustainable energy usage in the home. One approach is to give home residents feedback of their energy consumption, typically presented using a computer visualization. The expectation is that this feedback will motivate home residents to change their energy behaviors in positive ways. Yet little attention has been paid to what exactly motivates such behavioral change. This paper provides a brief overview of theories in psychology and social psychology on what does, and does not motivate sustainable energy action in the home.
Nonequilibrium representative ensembles for isolated quantum systems

description: An isolated quantum system is considered, prepared in a nonequilibrium initial state. In order to uniquely define the system dynamics, one has to construct a representative statistical ensemble. From the principle of least action it follows that the role of the evolution generator is played by a grand Hamiltonian, but not merely by its energy part. A theorem is proved expressing the commutators of field operators with operator products through variational derivatives of these products. A consequence of this theorem is the equivalence of the variational equations for field operators with the Heisenberg equations for the latter. A finite quantum system cannot equilibrate in the strict sense. But it can tend to a quasi-stationary state characterized by ergodic averages and the appropriate representative ensemble depending on initial conditions. Microcanonical ensemble, arising in the eigenstate thermalization, is just a particular case of representative ensembles. Quasi-stationary representative ensembles are defined by the principle of minimal information. The latter also implies the minimization of an effective thermodynamic potential.

Il ruolo delle emozioni in contesto glotto-geragogico
Creators: name: Cardona, Mario
Publisher: name: Studi di glottodidattica

Subjects: Emotions; learning processes; cognitive functions; emotions in the elderly; language education of the elderly

description: Emotions play a key role in human life. Indeed, emotions are essential for human life so much that the survival of the human species would be compromised in the absence of emotions. Emotions have an important biological function and they play a fundamental role in the human adaptation during the evolution processes. Emotions guide our decisions, goals, and interests. They are involved in the development of judgments and opinions on the world around us and they contribute significantly to the social and sentimental interaction of the individual within the society in which he/she lives. Given these premises, in this paper it will be argued the fundamental role of emotions in the learning processes and their deep connection with the cognitive functions. In particular, the increasing importance of emotions during human life will be taken in consideration. In this perspective, it will be highlighted that the elderly appreciate emotions and emotional experiences and several studies confirm that the processing of emotions do not deteriorate in the elderly, but rather they are improved. Therefore, for the language education of the elderly, emotions must be considered a central aspect.

WikiFolders: Augmenting the Display of Folders to Better Convey the Meaning of Files
Creators: name: Voida, Stephen
name: Greenberg, Saul
Publisher: name: University of Calgary
Year: 2008
Subjects: subject: Information storage and retrieval
subject: file organization
subject: Semantic organization, hierarchical file system, folders, wikis, WikiFolders

description: Hierarchical file systems and file browsers offer powerful capabilities for managing and organizing folders and files. Yet they lack robust tools for annotating and documenting these files—individually or collectively—with descriptive text. In contrast, Web pages and wikis make it easy to embed digital artifacts in explanatory images and prose, thus enabling rich and meaningful narratives. Unfortunately, they require considerable effort to manage individual files and ensure that the published content remains up-to-date. In this note, we describe WikiFolders, a hybrid system for annotating file folders that draws upon the strengths of both the hierarchical file system and wikis while mitigating their weaknesses.
Towards spin injection from silicon into topological insulators: Schottky barrier between Si and Bi2Se3

description: A scheme is proposed to electrically measure the spin-momentum coupling in the topological insulator surface state by injection of spin polarized electrons from silicon. As a first approach, devices were fabricated consisting of thin (<100nm) exfoliated crystals of Bi2Se3 on n-type silicon with independent electrical contacts to silicon and Bi2Se3. Analysis of the temperature dependence of thermionic emission in reverse bias indicates a barrier height of 0.34 eV at the Si-Bi2Se3 interface. This robust Schottky barrier opens the possibility of novel device designs based on sub-band gap internal photoemission from Bi2Se3 into Si.

description: We describe a minimal model of an autonomous Maxwell demon, a device that delivers work by rectifying thermal fluctuations while simultaneously writing information to a memory register. We solve exactly for the steady-state behavior of our model, and we construct its phase diagram. We find that our device can also act as a "Landauer eraser", using externally supplied work to remove information from the memory register. By exposing an explicit, transparent mechanism of operation, our model offers a simple paradigm for investigating the thermodynamics of information processing by small systems.

Extremely Rapid Usability Testing
Creators: name: Pawson, Mark

Subjects: subject: Usability
subject: Trade shows
subject: discount usability methods, rapid usability testing, trade shows

description: The trade show booth on the exhibit floor of a conference is traditionally used for company representatives to sell their products and services. However, the trade booth environment also creates an opportunity, for it can give the development team easy access to many varied participants for usability testing. The question is: can we adapt usability testing methods to work in such an environment? Extremely rapid usability testing (ERUT) does just this, where we deploy a combination of questionnaires, interviews, storyboarding, co-discovery and usability testing in a trade show booth environment. We illustrate ERUT in actual use during a busy photographic trade show. It proved effective for actively gathering quality user feedback in a rapid paced environment where time is of the essence.
