Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Autonomous driving in high-speed racing, as opposed to urban environments, presents significant challenges in scene understanding due to rapid changes in the track environment. Traditional sequential network approaches may struggle to meet the real-time knowledge and decision-making demands of an autonomous agent covering large displacements in a short time. This paper proposes a novel baseline architecture for developing sophisticated models capable of true hardware-enabled parallelism, achieving neural processing speeds that mirror the agent's high velocity. The proposed model (Parallel Perception Network (PPN)) consists of two independent neural networks, segmentation and reconstruction networks, running parallelly on separate accelerated hardware. The model takes raw 3D point cloud data from the LiDAR sensor as input and converts it into a 2D Bird's Eye View Map on both devices. Each network independently extracts its input features along space and time dimensions and produces outputs parallelly. The proposed method's model is trained on a system with two NVIDIA T4 GPUs, using a combination of loss functions, including edge preservation, and demonstrates a 2x speedup in model inference time compared to a sequential configuration. Implementation is available at: https://github.com/suwesh/Parallel-Perception-Network. Learned parameters of the trained networks are provided at: https://huggingface.co/suwesh/ParallelPerceptionNetwork.

description: Dynamic networking is a key factor for successful transnational organizations. The transcultural shift is a critical process that can enable cultural hybridization so as to inspire consensual identity and learning aptitude amongst worldwide members. The Global Learning Organization (GLO) model is re-conceptualized to bring about this cultural shift. E-learning seems an appropriate tool to generate effective transcultural communication for both culture and learning perspectives under the GLO model. A qualitative case study using document analysis and interviews is conducted to understand how transcultural communication is generated via e-learning under the GLO model in two fields. Findings reveal that firstly, trust is a core element in generating transcultural communication and the combination of face to face and e-learning can enable trust to be activated and developed. Secondly, the way to build trust varies depending on task characteristics: the detail-oriented tasks require more intense face to face communication than the concept-focused tasks. This study illustrates that design of various mixed learning pattern with strategies to build trust through the affective dimension will be key for the successful GLO.

description: Abstract

Australian cities can achieve net zero goals by emulating global best practices and lessons learnt from others focused on collaboration, iterative learning, accessibility, innovation, and affordability. Cities should adopt inclusive governance connecting government, industry, and communities to enable systemic change. Successful cities adopt a collaborative governance approach across government, private sector, and local communities to enable systemic change; both top down (Calgary and Edmonton) and bottom up (Melbourne), as well as exploring regional partnerships (Under2 Coalition) driving shared sustainability outcomes when facing similar climate challenges translating to local solutions. The cities take an iterative approach to policy development, leveraging data and predictive modelling to track progress and amplify success stories and Indigenous knowledge to diverse audiences. Industry coordination drives technological and supply chain solutions to shared challenges, facilitated by making a business case for adaptation (Germany and Denmark) and offering innovative financing (Japan and Zimbabwe). Overall, inclusive processes that enable markets and diffuse technologies in an affordable way underpin climate progress in leading cities working towards ambitious emissions goals.

 

In addition to sectoral impact, the theoretical application in this research is weighted to ensure a systems theory approach will impact long-term effective net-zero transition and effect a framework of sustainable solutions. A system of systems methodology ensures a collective application of both transitional and circular systemic theories which are necessary to underpin carbon neutral urban design. This will be effective with additional emphasis being placed on socio-ecological and sociotechnical systems. The combined systems theory approach provides a holistic framework which operates at a macro-level, hierarchical function of interconnected structures. This research has qualitatively determined which pathways of governance and adaptation have potential to realise success and will enable corrective planning and define the methodology of future design and developments of net zero cities.
A finite strain model for fiber angle plasticity of textile fabrics based on isogeometric shell finite elements

Subjects: subject: Computational Engineering, Finance, and Science (cs.CE)
subject: FOS: Computer and information sciences

description: This work presents a shear elastoplasticity model for textile fabrics within the theoretical framework of anisotropic Kirchhoff-Love shells with bending of embedded fibers proposed by Duong et al. (2023). The plasticity model aims at capturing the rotational inter-ply frictional sliding between fiber families in textile composites undergoing large deformation. Such effects are usually dominant in dry textile fabrics such as woven and non-crimp fabrics. The model explicitly uses relative angles between fiber families as strain measures for the kinematics. The plasticity model is formulated directly with surface invariants without resorting to thickness integration. Motivated by experimental observations from the picture frame test, a yield function is proposed with isotropic hardening and a simple evolution equation. A classical return mapping algorithm is employed to solve the elastoplastic problem within the isogeometric finite shell element formulation of Duong et al. (2022). The verification of the implementation is facilitated by the analytical solution for the picture frame test. The proposed plasticity model is calibrated from the picture frame test and is then validated by the bias extension test, considering available experimental data for different samples from the literature. Good agreement between model prediction and experimental data is obtained. Finally, the applicability of the elastoplasticity model to 3D shell problems is demonstrated.

description: Despite the decriminalization of abortion in Canada in 1988, women still face many barriers to abortion care. With the registration of Mifegymiso® (mifepristone, or RU486) in Canada in July 2015, there is hope that the gold-standard medication abortion could alleviate some of those barriers women face. In this thesis, I used data from a Canada-wide study exploring women’s abortion experiences by way of in-depth interviews to investigate mifepristone’s potential to alter the abortion care landscape. My thesis is comprised of two articles: one using selections from 174 interviews across five provinces, the other using 13 full interviews from Newfoundland as a case study. These papers suggest that women would be interested in using mifepristone once available in Canada, and identified both benefits of and concerns about this method of early pregnancy termination. Despite many unanswered questions as to how and when Mifegymiso® will become available, the registration of this important abortifacient has the promise to increase access and expand choice for Canadian women. Malgré la décriminalisation de l’avortement en 1988, les femmes font toujours face à des obstacles de soins. Avec l'enregistrement de Mifegymiso® (mifépristone, ou RU-486) au Canada en Juillet 2015, il y a espoir que ce médicament d’avortement pourrait atténuer certains de ces obstacles auxquels les femmes sont confrontées. Dans cette thèse, j'ai utilisé les données d'une étude qui explore les expériences d’avortements des femmes à travers le Canada. Les données ont été récupérer par moyen d’entrevues en profondeur et enquête le potentiel du médicament mifépristone à améliorer le paysage de soins de l’avortement. Ma thèse est composée de deux articles: la première inclue une sélection parmi 174 entrevues dans cinq provinces et la deuxième inclus 13 entrevues comme étude de cas de la province de Terre-Neuve. Ces articles suggèrent que l'intérêt pour la mifépristone pourrait être élevé au Canada après l'intégration de ce médicament, et les femmes perçoivent plusieurs avantages à cette méthode de terminaison prématurée de la grossesse et que les femmes ont certaines préoccupations. Malgré qu'il y ait beaucoup de questions sans réponse quant à la façon et quand Mifegymiso® sera disponible, l'enregistrement de cet important abortif a la promesse d'accroître l'accès et élargir le choix pour les femmes canadiennes.

description: This dissertation focuses on the findings of a multi-case study centered around two public-private partnership (P3s) projects in Ontario: the Royal Ottawa Hospital and the Brampton Civic Hospital. Partnerships have become particularly important as a part of infrastructure procurement for all levels of government in Canada. While infrastructure public-private partnerships have grown in popularity, they remain a controversial means of procuring public assets. Considerable questions remain as to whether the mechanisms related to partnerships with the private sector represent a sufficient response to the challenges facing health care systems. As such, major avenues exist for contributions in the form of evidence-based examinations to the field of knowledge pertaining to hospital procurement. A body of research literature and review of public-private partnerships, including those with a particular focus on health-sector projects in Canada, has grown over the past two decades. This study contributes an analysis of the relationship between public and private partners to that literature, utilizing a conceptual lens developed out of complex evolutionary systems theory. The study is intended to examine the capacity of public managers entering into a public-private partnership arrangement to successfully activate agents and utilize the skill and knowledge of these agents, conduct joint fact finding and consensus building, and better understand how they have arranged and organized joint interactions between the public and private sector. The two case studies demonstrate the key inputs into the decision-making processes for what were formative health infrastructure partnership projects in Ontario, providing an assessment of the degree to which the government of Ontario was successful in managing a cooperative decision-making process that stressed inclusion and horizontal steering. Results find that public managers struggled in some ways to leverage an effective horizontal management style and engage in smart interventions to utilize expert knowledge to address knowledge gaps, contributing to stagnating negotiations and driving up transaction costs for the projects. Some noteworthy successes were experienced in the case of the Royal Ottawa Hospital in leveraging private-sector knowledge to develop performance metrics, and the approach to stakeholder engagement in this case presents positive lessons-learned for future P3 infrastructure projects.

description: Cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies target the underlying cause of cystic fibrosis (CF), and are generally well-tolerated; however, real-world studies indicate the frequency of discontinuation and adverse events (AEs) may be higher than what was observed in clinical trials. The objectives of this systematic review were to summarize real-world AEs reported for market-available CFTR modulators (i.e., ivacaftor (IVA), lumacaftor/ivacaftor (LUM/IVA), tezacaftor/ivacaftor (TEZ/IVA), and elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA)), and to identify ways in which the pharmacist on CF healthcare teams may contribute to mitigating and managing these AEs. The MEDLINE, EMBASE, CINAHL, and Web of Science Core Collection online databases were searched from 2012 to Aug 1, 2020. Full manuscripts or conference abstracts of observational studies, case series, and case reports were eligible for inclusion. The included full manuscripts and conference abstracts comprised of 54 observational studies, 5 case series, and 9 case reports. The types of AEs reported generally aligned with what have been observed in clinical trials. LUM/IVA was associated with a higher frequency of respiratory-related AE and discontinuation in real-world studies. A signal for mental health and neurocognitive AEs was identified with all 4 CFTR modulators. A systematic approach to monitoring for AEs in people with CF on CFTR modulators in the real-world setting is necessary to help better understand potential AEs, as well as patient characteristics that may be associated with higher risk of certain AEs. Pharmacists play a key role in the safe initiation and monitoring of people with CF on CFTR modulator therapies.

description: Criminalized women are becoming more prominent in the prison show genre, outlining the need to examine the possible troublesome portrayals of this often invisible population. This thesis uses intersectionality to conduct a qualitative content analysis to explore themes of race, class, gender, and sexuality in relation to woman characters within the popular series Orange is the New Black (OITNB). It is found that OITNB is a departure from most mass media depictions of criminalized women in the sense that it reflects many of the racial demographic realities of woman penal institutions, while often representing minorities in complex, rather than reductionist manners. OITNB addresses issues associated with class structure and inequalities to shed light upon the reality of socioeconomic injustices of the incarcerated to its viewers. OITNB also raises questions on hegemonic gendered presentations through displaying atypical gender identities and roles, especially with respect to beautification, motherhood and friendships. Finally, OITNB offers an original approach in representing the sexuality of the women by depicting various sexual identities. Through analyzing these characters and themes, this thesis concludes that, although problematic portrayals of incarcerated women are present in the show, OITNB displays a departure from past displays of the incarcerated in Anglophone media, showing that film and television are able to portray this population in a humanized, yet entertaining manner.

description: The aggregate interference distribution in cognitive radio networks is studied in a rigorous and analytical way using the popular Poisson point process model. While a number of results are available for this model for non-cognitive radio networks, cognitive radio networks present extra levels of difficulties for the analysis, mainly due to the exclusion region around the primary receiver, which are typically addressed via various ad-hoc approximations (e.g., based on the interference cumulants) or via the large-deviation analysis. Unlike the previous studies, we do not use here ad-hoc approximations but rather obtain the asymptotic interference distribution in a systematic and rigorous way, which also has a guaranteed level of accuracy at the distribution tail. This is in contrast to the large deviation analysis, which provides only the (exponential) order of scaling but not the outage probability itself. Unlike the cumulant-based analysis, our approach provides a guaranteed level of accuracy at the distribution tail. Additionally, our analysis provides a number of novel insights. In particular, we demonstrate that there is a critical transition point below which the outage probability decays only polynomially but above which it decays super-exponentially. This provides a solid analytical foundation to the earlier empirical observations in the literature and also reveals what are the typical ways outage events occur in different regimes. The analysis is further extended to include interference cancelation and fading (from a broad class of distributions). The outage probability is shown to scale down exponentially in the number of canceled nearest interferers in the below-critical region and does not change significantly in the above-critical one. The proposed asymptotic expressions are shown to be accurate in the non-asymptotic regimes as well.

description: Bidirectional transformers excel at sentiment analysis, and Large Language Models (LLM) are effective zero-shot learners. Might they perform better as a team? This paper explores collaborative approaches between ELECTRA and GPT-4o for three-way sentiment classification. We fine-tuned (FT) four models (ELECTRA Base/Large, GPT-4o/4o-mini) using a mix of reviews from Stanford Sentiment Treebank (SST) and DynaSent. We provided input from ELECTRA to GPT as: predicted label, probabilities, and retrieved examples. Sharing ELECTRA Base FT predictions with GPT-4o-mini significantly improved performance over either model alone (82.50 macro F1 vs. 79.14 ELECTRA Base FT, 79.41 GPT-4o-mini) and yielded the lowest cost/performance ratio (\$0.12/F1 point). However, when GPT models were fine-tuned, including predictions decreased performance. GPT-4o FT-M was the top performer (86.99), with GPT-4o-mini FT close behind (86.70) at much less cost (\$0.38 vs. \$1.59/F1 point). Our results show that augmenting prompts with predictions from fine-tuned encoders is an efficient way to boost performance, and a fine-tuned GPT-4o-mini is nearly as good as GPT-4o FT at 76% less cost. Both are affordable options for projects with limited resources.

description: We analyse linearised field equations around the Minkowski metric with its standard flat parallel transport in models of Newer GR, that is quadratic actions in terms of nonmetricity tensor. We show that half of the freedom in choosing the model parameters is immediately fixed by asking for reasonable properties of tensors and vectors, defined with respect to spatial rotations, and accurately describe the much more complicated sector of scalars. In particular, we show that, from the teleparallel viewpoint, the model of STEGR with addition of a gradient squared of the metric determinant exhibits three halves new dynamical modes, and not just one like it was previously claimed.

description: Phase transformations induced by short optical pulses are mainstream in studies on the dynamics of cooperative electronic states. We present a semi-phenomenological modeling of spacio-temporal effects expected when optical excitons are intricate with the order parameter as in, e.g., organic compounds with neutral-ionic ferroelectric phase transitions. A conceptual complication appears here, where both the excitation and the ground state ordering are built from the intermolecular electronic transfer. To describe both thermodynamic and dynamic effects on the same root, we adopt, for the phase transition, a view of the Excitonic Insulator - a hypothetical phase of a semiconductor that appears if the exciton energy becomes negative. After the initial pumping pulse, a quasi-condensate of excitons can appear as a macroscopic quantum state that then evolves, while interacting with other degrees of freedom which are prone to an instability. The self-trapping of excitons enhances their density, which can locally surpass a critical value to trigger the phase transformation. The system is stratified in domains that evolve through dynamical phase transitions and may persist even after the initiating excitons have recombined.
Show-business for ugly people?: media politics and e-democracy

description: The TV remote has long been a symbol of apathy, a way to switch off from public life. Interactive media, on the other hand, are valorised for allowing participation and deliberation. E-government initiatives are being pursued by state authorities in the hope that they may encourage interest in politics and efficiently provide information to citizens. This paper looks at the democratic possibility of e-government, locating it in the medium’s ability to encourage networks, knowledge and creativity. However, these are outcomes that occur at the level of the self, rather than the public, and are enabled by the information and services aspects of e-government – not necessarily by democratic deliberation. The press and broadcasting successfully congregated audiences and formed narratives that defined the ambitions (and shortcomings) of government in relation to society. Now audiences are turning increasingly to entertainment, reality TV and celebrities, and losing interest in both politicians and the news. How can governments fulfil the public’s need for leadership? The shift towards private life may provide the answers that e-government has been looking for. We argue that e-government initiatives are unlikely to succeed in overcoming political apathy until they produce narratives relevant to contemporary culture.

description: We contribute to the lively debate in current scholarship on the Leibnizian calculus. In a recent text, Arthur and Rabouin argue that non-Archimedean continua are incompatible with Leibniz's concepts of number, quantity and magnitude.
 They allege that Leibniz viewed infinitesimals as contradictory, and claim to deduce such a conclusion from an analysis of the Leibnizian definition of quantity. However, their argument is marred by numerous errors, deliberate omissions, and misrepresentations, stemming in a number of cases from flawed analyses in their earlier publications.
 We defend the thesis, traceable to the classic study by Henk Bos, that Leibniz used genuine infinitesimals, which he viewed as fictional mathematical entities (and not merely shorthand for talk about more ordinary quantities) on par with negatives and imaginaries.

Year: 2024

In “Developing Sustained SoTL Journeys and Identities,” Janice Miller-Young and Nancy L. Chick argue that SoTL is no longer just a grassroots movement of individual faculty committed to taking teaching and learning seriously; it has become professionalized as a field of study as more of us seek to integrate SoTL into our careers. Many academics begin as explorers who come from different disciplines, institution types, career stages, and countries.  Some choose to stay, making SoTL not only what they do, but also who they are—not just through new knowledge and skills but also their career and indeed their identity. This book is called Becoming a SoTL Scholar to acknowledge that we are always in a state of learning and reckoning with our academic identities, and thus we are always becoming. The collection illustrates a variety of entry points, pathways, and strategies for academics to develop and sustain a career in SoTL; it also uses a system of wayfinding icons to help readers choose their own adventure.

description: Anforderungen sind die Basis für jede Produktentwicklung. Anforderungen geben der Produktentwicklung Ziel und Richtung. Die Qualität eines Produktes wird erkennbar durch den Vergleich mit den ursprünglichen Anforderungen: Quality is conformance with requirements. Der Erhebung der Anforderungen, der Anforderungsermittlung, kommt dementsprechend eine hohe Bedeutung in der Produktentwicklung zu. Eigenschaften des Produktes umfassen funktionale Aspekte und nicht-funktionale Eigenschaften. Funktionale Produkteigenschaften beschreiben, was einem Benutzer mit dem Produkt möglich gemacht werden soll, welcher Funktionsumfang das Produkt einem Benutzer zur Verfügung stellt. Viele Methoden und Techniken im Softwareengineering sind auf das Erkennen und Spezifizieren der Produktfunktionalität gerichtet. Zu den nicht-funktionalen Eigenschaften gehören Qualitätseigenschaften. Es gibt eine Vielzahl von Qualitätseigenschaften, die für ein Produkt festgelegt werden können. Man kann diese Qualitätseigen- schaften in unterschiedliche Klassen einteilen: Eigenschaften, die sich auf das Produkt selbst beziehen und die Produktqualität betreffen (Product Quality) und Eigenschaften, die die Qualität in der Produktnutzung zum Thema haben (Quality in Use). Gerade diese Anforderungen, die sich auf die Produktnutzung, also auf Usability und User Experience beziehen, sind häufig für den Produkterfolg von größter Bedeutung. Insofern sucht man Möglichkeiten, das klassische Requirements Engineering zu erweitern und Usability Engineering bzw. User Experience Methoden aber auch kreative Ideenfindungsprozesse und Innovationsprozesse zu integrieren. Mit der menschzentrierten Gestaltung wird schon im Entwicklungsprozess einer hohen Qualität in der Nutzung in besonderer Weise Rechnung getragen. Erhobene Nutzungsanforderungen werden in einem iterativen Prozess evalu- iert. Damit wird das Entwicklungsergebnis qualitätsgesichert. Aber auch andere Methoden rücken in das Blickfeld. So wird in letzter Zeit auch Design Thinking als Möglichkeit gesehen, besonders Innovation und Ideenfindung in den Entwicklungsprozess speziell natürlich in den Prozess der Anforderungsanalyse zu integrieren. Mit dem hier vorgestellten Human Centered Requirements Engineering soll ein Weg zur nahtlosen Integration verschiedener Vorgehensweisen aus Usability Engineering, Softwareengineering und Innovationsmanagement aufgezeigt werden. Durch Verzahnung spezifischer Vorgehensmodelle sollen disziplinübergreifende Synergien organisiert werden. Dieser Erkenntnis folgend soll im Folgenden eine Modell-Integration vorgestellt werden, die sowohl Softwareingenieure als auch Designer abholt und sie in die Lage versetzt, danach in „synchronisierten mentalen Modellen“ koordiniert in einem Entwicklungsprojekt zusammenzuarbeiten.

description: Die vorliegende Studie untersuchte, ob ein Roboter Menschen motivieren kann, zu helfen. Konkret ging das Projektteam der Frage nach, wie ein Roboter Mitarbeiter1 eines KMUs überzeugen kann, die Spülmaschine auszuräumen. Dazu adaptierte das Projektteam in der Mensch-Computer-Interaktion geltende persuasive Prinzipien auf die MRI und wandte sie in Form eines Sprachinterfaces sowie in Form bestimmter Persönlichkeitsaspekte an. In einer ersten initialen Phase beobachtete das Projetteam das Ausräumverhalten der Mitarbeiter über zwei Wochen und ermittelte dadurch den Ist- Zustand. Die anschließende zweite Phase stellte ein Wizard-of- Oz-Experiment dar, in dem der motivierende Roboter SKIWO ebenfalls für zwei Wochen eingesetzt wurde. Durch den Einsatz von SKIWO wurde die Spülmaschine häufiger ausgeräumt. Anschließende Untersuchungen in Form des Godspeed Questionnaires sowie eines Interviews mit 20 Mitarbeitern stützen und konkretisieren dieses Ergebnis. So nahmen die Mitarbeiter den Roboter als sehr sympathisch und freundlich wahr. Er konnte, laut Aussagen der Mitarbeiter, diesen sogar ins Gewissen reden. Die gewonnenen Erkenntnisse können die Gestaltung von Sprache und Persönlichkeit bei Robotern verbessern und liefern neue Einblicke in die persuasive Mensch-Roboter-Interaktion.

In unserem Workshop nehmen wir die TeilnehmerInnen mit auf einen Design-Exkurs: Wir stellen Ergebnisse bisheriger Forschung vor, wie NutzerInnen über Privatheitsrisiken denken, und erweitern diese um die Perspektive professioneller UXlerInnen. Vor allem wird es kreativ und praktisch: In einem Hands-on wollen wir gemeinsam Lösungen für die wahrgenommenen Risiken in prototypische Designs überführen und diskutieren.

description: Stetig steigt die Zahl der UX-gläubigen Unternehmen. Eine gute User Experience wird zunehmend bedeutsamer und Unternehmen ergreifen Maßnahmen, um diese nachhaltig in ihre Produkte als auch Arbeitsweise zu implementieren. Dabei stehen häufig Usability-Tests mit Endanwendern sowie Fragebögen im Mittelpunkt. UX-Methoden werden produktfokussiert eingesetzt und UX-Metriken werden genutzt, um diese zu messen. Doch ist das schon alles, was UX zu bieten hat? Eine gute User Experience zu liefern, fängt weder beim Usability-Test an, noch hört sie dort auf! Sie ist nicht nur an und in digitalen Produkten bzw. Benutzungsschnittstellen vorzufinden, sondern umfasst alle Schnittstellen zwischen den Nutzern bzw. Beschäftigten und dem Unternehmen. Mit wachsendem Interesse an einer einheitlichen und systemübergreifenden UX stehen Unternehmen vor der Herausforderung eine menschzentrierte Ge- staltung strategisch im Unternehmen einzusetzen. UX Metriken und Kennzahlen helfen dabei, den Einfluss einer menschzentrierten Gestaltung auf den Unternehmenserfolg abzubilden und den Erfolg einer UX-Strategie zu messen.

description: Künstliche Intelligenz (KI) wird die Art verändern, wie wir mit Systemen interagieren. Die KI wird als Partner des Menschen auf- treten und eine Zusammenarbeit zwischen Mensch und KI wird im Vordergrund stehen. Hier stellt sich die Frage, wie diese Zusammenarbeit von Usability und User Experience Professionals konzipiert werden kann. Welche Aufgaben übernimmt die KI? Welche Aufgaben übernimmt der Mensch? Und wie sieht die Kooperation zwischen Mensch und KI aus? Eingebettet in einen menschzentrierten Gestaltungsprozess wurden im Rahmen eines Projekts des Mittelstand 4.0-Kompetenzzentrums Usability diese Fragen adressiert. Als Ansatz zur Gestaltung dieser Mensch-KI-Zusammenarbeit wurde ein Workshop entwickelt, in welchem die auf die KI-Thematik angepasste Me- thode des Service-Blueprints genutzt wurde. In dem Workshop lernen die Teilnehmenden den KI-Service-Blueprint-Workshop kennen und probieren ihn an einem konkreten Beispiel aus.

description: Der Standpunkt des Arbeitskreises “The Positive Xˮ ist, dass wir als User Experience Designer*innen die Gestaltung für Menschen und ihr subjektives Wohlbefinden vorantreiben können. Dabei ist ein Schwerpunkt der Austausch über Konzepte, die den Arbeitskontext und die Arbeitserfüllung sowie positive Erlebnisse und Wohlbefinden in Freizeit und Zusammenleben adressieren. Unser Ziel ist, eine Balance zwischen den beiden Extremen zu finden, nicht das Entweder-oder. Eine Frage von Interessierten ist jedoch immer wieder, wie dieses Mindset im Unternehmen integriert werden kann. In diesem Paper und beim Workshop können Interessierte hierzu einen Einblick gewinnen: Nach einer Einführung zur “positiven User Experience” zeigen wir, wie das Mindset in Unternehmen bereits gelebt wird. Danach tauschen sich die Teilnehmenden über die Herausforderungen und Chancen in ihrem Unternehmen aus. So können die Teilnehmenden Einblicke in die Erfahrungen der anderen und Gedankenanstöße mitnehmen, die eine Integration im eigenen Unternehmen ermöglichen können.

FE model of roofing systems

description: The development of the construction industry brought the new methods of structural design, which have been introduced to engineers, although overall this phenomenon has increased building costs. A cost-effective construction is one of the major decision points during the definition of any engineering project, therefore, due to the opposing concepts of these two statements, revising design standards and codes are essential in order to provide adequate and cost-effective design requirements. A single-ply roof system is a relatively new method of roof construction that has been used in the building industry in recent decades, which seems to have undergone dramatic changes due to significant structural failures that have occurred through the years. Wind-induced damage on flat roofs is a common problem for low-rise buildings and much of this damage is initiated when the steel deck roof fails, leading to the overall roofing system collapse. The FM (Factory Mutual) design recommendations, which is a standard that recommends allowable dimensions and wind rating for the roofing products, have provided tabulated steel deck span dimensions and fasteners distance for many years. To update the FM design recommendations extensive experimental and analytical investigations are required. In the current study an experimental program was conducted at the National Research Council of Canada (NRC) on flat roofing systems, for simulating the wind uplift effect on several roofing systems samples, as recommended by FM design recommendations. A Finite Element Model (FEM) of the same roofing systems as those used in the experimental cases was developed and different loading patterns were analysed for providing a better simulation of the deflection, moments and forces responses, as measured during the experiments. The FEM was validated with the experimental results and was further employed for applying the FE analysis for more steel deck span dimensions and wind rating cases, as provided in the FM design recommendations tables. These results were reported to the Single Ply Roof Industry (SPRI) Committee where the updating of the FM design tables is currently under discussion.

description: Increasing the sweep rate of mid-infrared (MIR) frequency-swept sources offers significant potential for various high-speed spectroscopy-based applications. While continuous-wave frequency-swept lasers have achieved sweep rates up to 1 MHz, a recently demonstrated time-stretched ultrashort pulsed laser has reached a significantly higher sweep rate, up to tens of MHz. However, the previous system relied on a bulky femtosecond optical parametric oscillator and produced only ~30 discrete spectral elements due to the use of a free-space time stretcher. In this work, we present a fiber-based frequency-swept MIR source that utilizes the frequency down-conversion of time-stretched near-infrared pulses, employing a compact mode-locked fiber laser and telecommunication fiber. As a proof-of-concept demonstration, we performed MIR spectroscopy of methane gas around 3.4 um at a rate of 50 MSpectra/s, capturing 220 spectral elements over a range of 19.0 cm-1. This compact and robust high-speed MIR frequency-swept laser system holds the potential for deployment in field applications.
