Transverse Wind Velocity Recorded in Spiral-Shell Pattern

Publisher: name: arXiv
Year: 2023
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The propagation speed of a circumstellar pattern revealed in the plane of the sky is often assumed to represent the expansion speed of the wind matter ejected from a post-main-sequence star at the center. We point out that the often-adopted isotropic wind assumption and the binary hypothesis as the underlying origin for the circumstellar pattern in the shape of multilayered shells are, however, mutually incompatible. We revisit the hydrodynamic models for spiral-shell patterns induced by the orbital motion of a hypothesized binary, of which one star is losing mass at a high rate. The distributions of transverse wind velocities as a function of position angle in the plane of the sky are explored along viewing directions. The variation of the transverse wind velocity is as large as half the average wind velocity over the entire three dimensional domain in the simulated models investigated in this work. The directional dependence of the wind velocity is indicative of the overall morphology of the circumstellar material, implying that kinematic information is an important ingredient in modeling the snapshot monitoring (often in the optical and near-infrared) or the spectral imaging observations for molecular line emissions.

description: We design and fabricate ultra-low-loss tapered optical fibers (TOFs) with minimal lengths. We first optimize variations of the torch scan length using the flame-brush method for fabricating TOFs with taper angles that satisfy the adiabaticity criteria. We accordingly fabricate TOFs with optimal shapes and compare their transmission to TOFs with a constant taper angle and TOFs with an exponential shape. The highest transmission measured for TOFs with an optimal shape is in excess of 99.7 % with a total TOF length of only 23 mm, whereas TOFs with a constant taper angle of 2 mrad reach 99.6 % transmission for a 63 mm TOF length.
Evaluation methods for a community-centered human subjects protections and research ethics training: Your Rights in Research
Creators: name: Deane-Polyak, Maya
Publisher: name: Digital Repository at the University of Maryland
Year: 2020
Subjects: subject: Public health

description: Any research project that involves human subjects requires ethical considerations and protections for individuals who enroll as participants. However, because the responsibility of these protections is often entrusted to the researchers, participants may not be aware of, and fully understand the rights to which they are entitled. The proposed training takes a preventative approach to increase awareness of protections available to individuals before they enroll in future research. The training also consists of an evaluation component to assess the extent to which the training program affects Prince George’s County residents’ decision-making ability regarding future research participation. The overarching goal of the project is to equip Prince George’s County residents so that they are able to make informed decisions about research participation that ultimately preserve, optimize, and protect their health and quality of life to the fullest extent possible.

description: Recent abrupt changes of CW Leonis may indicate that we are witnessing the moment that the central carbon star is evolving off the Asymptotic Giant Branch (AGB) and entering into the pre-planetary nebula (PPN) phase. The recent appearance of a red compact peak at the predicted stellar position is possibly an unveiling event of the star, and the radial beams emerging from the stellar position resemble the feature of the PPN Egg Nebula. The increase of light curve over two decades is also extraordinary, and it is possibly related to the phase transition. Decadal-period variations are further found in the residuals of light curves, in the relative brightness of radial beams, and in the extended halo brightness distribution. Further monitoring of the recent dramatic and decadal-scale changes of this most well-known carbon star CW Leonis at the tip of AGB is still highly essential, and will help us gain a more concrete understanding on the conditions for transition between the late stellar evolutionary phases.

description: Plasma in the Sun's hot corona expands into the heliosphere as a supersonic and highly magnetized solar wind. This paper provides an overview of our current understanding of how the corona is heated and how the solar wind is accelerated. Recent models of magnetohydrodynamic turbulence have progressed to the point of successfully predicting many observed properties of this complex, multi-scale system. However, it is not clear whether the heating in open-field regions comes mainly from the dissipation of turbulent fluctuations that are launched from the solar surface, or whether the chaotic "magnetic carpet" in the low corona energizes the system via magnetic reconnection. To help pin down the physics, we also review some key observational results from ultraviolet spectroscopy of the collisionless outer corona.

description: Africa experiences a disproportionate amount of the global disease burden, and existing health care centers struggle to meet everyday patient needs. During a disease epidemic, this inability to accommodate communities is exacerbated by a lack of resources to diagnose and treat infectious disease as well as a physical separation from the location of outbreaks. This thesis investigates how patients of disease outbreaks in Africa can be better accommodated through the exploration of a modular health facility capable of treating communities no matter when and where an outbreak occurs. Outbreaks unexpectedly affect vulnerable populations, and immediate action is crucial to contain the disease. The current Ebola outbreak in the Democratic Republic of Congo is utilized as a case study in this thesis, considering its relevance as an ongoing epidemic. Due to the abrupt and destructive nature of disease, a modular and flexible health facility is needed to handle any outbreak in any location.

description: We study two-dimensional $\mathcal{N}=(2,2)$ supersymmetric gauged linear sigma models (GLSM) on the $Ω$-deformed sphere, $S^2_Ω$, which is a one-parameter deformation of the $A$-twisted sphere. We provide an exact formula for the $S^2_Ω$ supersymmetric correlation functions using supersymmetric localization. The contribution of each instanton sector is given in terms of a Jeffrey-Kirwan residue on the Coulomb branch. In the limit of vanishing $Ω$-deformation, the localization formula greatly simplifies the computation of $A$-twisted correlation functions, and leads to new results for non-abelian theories. We discuss a number of examples and comment on the $ε_Ω$-deformation of the quantum cohomology relations. Finally, we present a complementary Higgs branch localization scheme in the special case of abelian gauge groups.

description: This study aims to address the nationwide gap in AADT data on NFAS roads in U.S. With a Spatial Autoregressive Model as a benchmark, two machine-learning approaches, i.e. Artificial Neural Network and Random Forest, show notable improvement in the accuracy of estimating AADT according to five measures, i.e. MSE, RSQ, RMSE, MAE, and MAPE. A data-mining of the built-in environment from three perspectives, i.e. on-road and off-road features, network centralities, and neighboring influences, paves the way for AADT estimation, which covers 87 variables in centrality, neighboring traffic, demographics, employment, land-use diversity, road network density, urban design, destination accessibility, etc. Data integration using different buffering sizes and statistical analysis of linearity and monotonicity promote the variable selection for estimation. When implementing the machine-learning approaches, not only the estimation performance is analyzed, but also the relationship between each variable and AADT, the interplays among variables, variable importance measures are thoroughly discussed.

description: In dieser Masterarbeit wird der Einsatz von Deepfakes im Marketing untersucht. Es geht darum, Deepfake-Marketing zu analysieren und vier eigene Deepfakes zu erstellen, um mögliche Effekte bei Rezipienten zu erkennen. Dazu wird die folgende Forschungsfrage „Welche Effekte lösen hyperpersonalisierte Werbebotschaften durch Deepfakes bei Probanden aus?“ aufgestellt. Für die Beantwortung der Forschungsfrage wird zunächst die Personalisierung von Werbung, sowie Deepfakes im Allgemeinen thematisiert. Im Anschluss daran wurden die Vor- und Nachteile der Hyperpersonalisierung durch die Integration von Deepfakes in die Werbung analysiert und vier eigene Deepfakes auf Basis realer Video-Werbungen generiert. Zur Überprüfung der möglichen Effekte bei Rezipienten wurde eine Online-Umfrage erarbeitet, bei der 22 Probanden die vier selbst produzierten Deepfakes sahen und Fragen zu ihrer persönlichen Einstellung zur Personalisierung durch Deepfakes mitteilten. Die Ergebnisse der nicht repräsentativen Umfrage zeigen, dass sich die Auswirkungen bei hyperpersonalisierten Werbebotschaften durch Deepfakes primär in zwei Kategorien einordnen lassen: positive Überraschung und Misstrauen. Im Detail können die Probanden Deepfakes nicht eindeutig erkennen und wünschen sich eine offene Deklarierung von Deepfake- Inhalten in der Werbung. Bereits 4 von 10 Teilnehmern würden sogar ihre Daten für die Produktion von Deepfake-Werbung zur Verfügung stellen. Doch auch die Angst vor dem Missbrauch persönlicher Daten und möglichen Gefahren, welche von Deepfakes ausgehen könnten, belasten die Teilnehmer. Für zukünftige Forschung bietet sich an, zur Produktvermarktung mit Deepfake-Werbung weiterzuforschen. Dafür bedarf es in erster Linie eine umfangreichere Datenerhebung.

description: Testing & Commissioning (T&C) for a $2 Billion project generally consists of more than ten thousand tests, and the Purple Line Light Rail system being constructed in Maryland is no exception. The Purple Line Light Rail is expected to have at least twenty thousand tests conducted in its T&C phase over the next 3-4 years. Given the number of tests, their pre-requirements, resources (manpower, equipment, facilities) and the test reporting procedures to be used to comply with the Maryland Transit Administration (MTA), the Purple Line Transit Constructors (PLTC) felt a need for an online system that could be used to log and track tests. This Thesis focuses on the formalized application of Systems Engineering processes, in accordance with ISO/IEC/IEEE 15288:2015, to the development of this test tracking tool. The Stakeholder requirements given by MTA and PLTC are converted to System requirements, and a Test Plan for the tool is developed in parallel. The tool is designed by PLTC in collaboration with a subcontractor to meet the System requirements and will be tested before going live.

description: Lernverlaufsdiagnostik soll reliabel und möglichst kurz sein, m im Unterricht ökonomisch einsetzbar zu sein. Ziel eines kurzen Tests ist es, dass Schülerinnen und Schüler mit Lernschwierigkeiten im Testzeitraum zur Informationsgewinnung ausreichend Items bearbeiten. Die Bearbeitungsgeschwindigkeit ist hierfür ausschlaggebend. Der vorliegende Beitrag untersucht die Bearbeitungsgeschwindigkeit und -genauigkeit auf Item- und Testebene der – als Speedtests konstruierten – Lesetests der Onlineplattform Levumi.de von Schülerinnen und Schülern mit und ohne sonderpädagogischen Unterstützungsbedarf. Die Ergebnisse zeigen, dass Schülerinnen und Schüler mit Unterstützungsbedarf die Items im Schnitt langsamer und fehlerhafter bearbeiten als Schülerinnen und Schüler ohne Unterstützungsbedarf trotz eines höheren Durchschnittsalters zum Testzeitpunkt. Es wird diskutiert, welche Schlüsse auf Grundlage der Bearbeitungsgeschwindigkeit gezogen werden können und inwiefern sich „gute Testergebnisse“ als Richtwerte für Lehrkräfte ableiten lassen. Progress monitoring tests must be as shortas possible in order to be used economically in the classroom. To ensure reliable measurement, it is necessary that students with learning difficulties are able to complete an adequate number of items during the test period. This article describes an approach based on the average processing speed per item on the online platform Levumi in reading. Students with special needs complete the speed-tests slower and make more mistakes despite a higher average age at the time of testing. The conclusions that can be drawn on the basis of the processing speed and the extent to which guidelines for defining a good test result can be derived are discussed.
title: Service engagement and disengagement in first episode psychosis
Creators: name: McPhilemy, Kirsty
Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Early intervention, engagement, first episode psychosis, predictors, schizophrenia

description: Aims: The effectiveness of early intervention (EI) services for people with first episode psychosis is dependent on meaningful service engagement. Difficulties with engagement in EI services increases risk of drop out which has implications for poorer functioning and poorer clinical outcomes. The purpose of the current study was to explore associations between engagement, clinical, and relational variables, and to investigate factors that predict service engagement in an early intervention service for first episode psychosis. Methods: The study gathered prospective routine date from an early intervention service using a naturalistic cohort of 83 individuals with first episode psychosis in Scotland, UK. Cross sectional associations between engagement, attachment, and carer’s burden of care were explored. Sociodemographic, clinical and psychiatric predictors of engagement were examined using hierarchical and stepwise regression. Results: Poorer clinician engagement as measured by the service engagement scale (SES) was associated with greater positive symptoms and greater disorganisation, poorer insight, more effortful caregiving and higher number of adverse childhood experiences. In regression analysis, only lack of insight predicted engagement at 12-weeks. We found that engagement scores at 12-weeks predicted engagement at 26-weeks. Additionally, engagement scores at an earlier point of treatment were predictive of psychiatric recovery at 12-month follow-up. Conclusions: Our findings suggest that clinicians in early intervention services are well placed to identify those who are at risk of poorer engagement and subsequent poorer psychiatric outcomes which has implications for treatment planning. Additionally, people who lacked insight into their diagnosis of psychosis and need for treatment, as rated by clinicians, were rated with poorer levels of service engagement. This may reflect clinicians framework of psychosis and mental illness and might suggest the need for clinicians to work within the patients own beliefs of their experiences and framework of mental illness to help increase engagement.

description: We present an analysis of the HI absorption in a sample of 101 flux-selected radio AGN (S_1.4 GHz > 50 mJy) observed with the Westerbork Synthesis Radio Telescope (WSRT). HI absorption is detected in 32 galaxies, showing a broad variety of widths, shapes and kinematical properties. We characterize the HI spectra of the individual detections using the busy function (Westmeier et al. 2014). With the goal of identifying different morphological structures of HI, we study the kinematical and radio source properties of the detections as function of their width. Narrow lines (FWHM < 100 km/s) mostly lie at the systemic velocity and are likely produced by regularly rotating HI disks or clouds. More HI disks can be present among galaxies with lines of intermediate widths (100 km/s < FWHM < 200 km/s), however the HI in these sources is more unsettled. We study the asymmetry parameter and blueshift/redshift distribution of the lines. We argue that if a profile is broad, it is also asymmetric and shifted relative to the systemic velocity because it is tracing unsettled HI gas. Besides three of the broadest (up to FW20 = 825 km/s) detections, which are associated with gas-rich mergers, we find three new cases of blueshifted broad wings (with FW20 >= 500 km/s). These detections are good candidates for being HI outflows. The detection rate of HI outflows is 5 percent in the total radio AGN sample. This fraction represents a lower limit, however it could suggests that, if outflows are a characteristic phenomenon of all radio sources, they would have a short depletion timescale compared to the lifetime of the AGN. Blueshifted and broad/asymmetric lines are more often present among young, compact sources, suggesting that in these AGN the HI is likely to be unsettled. This may arise due to jet-cloud interactions, as young radio sources clear their way through the rich ambient gaseous medium.

description: In this paper, we reconsider the single interval Rényi entropy of a free compact scalar on a torus. In this case, the contribution to the entropy could be decomposed into classical part and quantum part. The classical part includes the contribution from all the saddle points, while the quantum part is universal. After considering a different monodromy condition from the one in the literature, we re-evaluate the classical part of the Rényi entropy. Moreover, we expand the entropy in the low temperature limit and find the leading thermal correction term which is consistent with the universal behavior suggested in arXiv:1403.0578 [hep-th]. Furthermore we investigate the large interval behavior of the entanglement entropy and show that the universal relation between the entanglement entropy and thermal entropy holds in this case.

description: We study the classical dynamics of many interacting particles in a periodically driven one-dimensional (1D) system. We show that under the rotating wave approximation (RWA), a short-distance 1D interaction ($δ$ function or hard-core interaction), becomes a long-distance two-dimensional (2D) interaction which only depends on the distance in the phase space of the rotating frame. The RWA interaction describes the effect of the interaction on the slowly changing amplitude and phase of the oscillating particles, while the fast oscillations take on the role of a force carrier, which allows for interaction over much larger effective distances.
description: We make sufficient changes compared to version 2. Here, we focus on the classical dynamics and extend the paper. We add new numerical simulation results to this version

description: COVID-19 may trigger an acute hyperinflammatory syndrome characterised by heightened levels of acute phase reactants and is associated with adverse outcomes among hospitalised individuals. The relationship between 48-hour changes in acute phase reactants and adverse outcomes is unclear. This study evaluated the relationship between change in four acute phase reactants (interleukin-6, procalcitonin, ferritin, and C-reactive protein), and the risk for in-hospital death and invasive mechanical ventilation. A retrospective cohort among 2,523 adult patients hospitalised with COVID-19 pneumonia was conducted. Changes in IL-6, procalcitonin, ferritin, and CRP from admission to 48 h after admission were recorded. Delta was calculated using the difference in each acute phase reactant at admission and at 48-hours. Delta in acute phase reactants and the risk for in-hospital death and invasive mechanical ventilation was assessed using logistic regression models adjusting for demographics and comorbidities. Patients with both admission and 48-hour measurement for interleukin-6 (IL-6) (n = 541), procalcitonin (n = 828), ferritin (n = 1022), and C-reactive protein (CRP) (n = 1919) were included. Baseline characteristics were similar across all four populations. Increases in ferritin associated with a heightened risk of in-hospital death (OR 1.00032; 95%CI 1.00007- 1.00056; p < .001) and invasive mechanical ventilation (OR 1.00035; 95%CI 1.00014- 1.00055; p = .001). Therefore, for every 100 ng/mL increase in ferritin, the odds for in-hospital death and invasive mechanical ventilation increase by 3.2% and 3.5%, respectively. Delta in ferritin is associated with in-hospital death and invasive mechanical ventilation. Other acute phase reactants were not associated with these outcomes among COVID-19 inpatients.

description: Bacterial infections are associated with acute exacerbations of chronic obstructive pulmonary disease (AECOPD), but the mechanism is incompletely understood. In a COPD observational study (NCT01360398), sputum samples were collected monthly at the stable state and exacerbation. Post-hoc analyses of 1307 non-typeable Haemophilus influenzae (NTHi) isolates from 20 patients and 756 Moraxella catarrhalis isolates from 38 patients in one year of follow-up were conducted by multilocus sequence typing (MLST). All isolates came from cultured sputum samples that were analyzed for bacterial species presence, apparition (infection not detected at the preceding visit), or acquisition (first-time infection), with the first study visit as a baseline. Strain apparition or new strain acquisition was analyzed by MLST. The odds ratio (OR) of experiencing an exacerbation vs. stable state was estimated by conditional logistic regression modelling, stratified by patient. The culture results confirmed a significant association with exacerbation only for NTHi species presence (OR 2.28; 95% confidence interval [CI]: 1.12–4.64) and strain apparition (OR 2.38; 95% CI: 1.08–5.27). For M. catarrhalis, although confidence intervals overlapped, the association with exacerbation for first-time species acquisition (OR 5.99; 2.75–13.02) appeared stronger than species presence (OR 3.67; 2.10–6.40), new strain acquisition (OR 2.94; 1.43–6.04), species apparition (OR 4.18; 2.29–7.63), and strain apparition (OR 2.78; 1.42–5.42). This may suggest that previous M. catarrhalis colonization may modify the risk of exacerbation associated with M. catarrhalis infection. The results confirm that NTHi and M. catarrhalis infections are associated with AECOPD but suggest different dynamic mechanisms in triggering exacerbations.

description: Queer history in Baltimore began long before the twentieth century. People who diverged from societal norms of gender and sexuality were always present in Baltimore’s history, and they can be seen through media representations and popular press of the time period. Even when representation of queerness in media was less common, stories of people who diverged from gender and sexual norms were still distributed to the public. Media representations provided inspiration and information to people who did not have access to a group of like-minded people through a distinct subculture. Queer Baltimoreans drew from media representations, early stages of a developing subculture, or their own personal thoughts and feelings to inform their gender and sexual identities. Despite the legal and social measures restricting these people from living their lives as freely as they might wish, they still found individualized ways to live life outside of gender and sexual norms.

description: Magnetic reconnection is believed to be the dominant energy release mechanism in solar flares. The standard flare model predicts both downward and upward outflow plasmas with speeds close to the coronal Alfvén speed. Yet, spectroscopic observations of such outflows, especially the downflows, are extremely rare. With observations of the newly launched Interface Region Imaging Spectrograph (IRIS), we report the detection of greatly redshifted ($\sim$125 km s$^{-1}$ along line of sight) Fe {\sc{xxi}} 1354.08Å emission line with a $\sim$100 km s$^{-1}$ nonthermal width at the reconnection site of a flare. The redshifted Fe {\sc{xxi}} feature coincides spatially with the loop-top X-Ray source observed by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI). We interpret this large redshift as the signature of downward-moving reconnection outflow/hot retracting loops. Imaging observations from both IRIS and the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) also reveal the eruption and reconnection processes. Fast downward-propagating blobs along these loops are also found from cool emission lines (e.g., Si {\sc{iv}}, O {\sc{iv}}, C {\sc{ii}}, Mg {\sc{ii}}) and images of AIA and IRIS. Furthermore, the entire Fe {\sc{xxi}} line is blueshifted by $\sim$260 km s$^{-1}$ at the loop footpoints, where the cool lines mentioned above all exhibit obvious redshift, a result that is consistent with the scenario of chromospheric evaporation induced by downward-propagating nonthermal electrons from the reconnection site.

DESCRIBING THE POOR: AN EXAMINATION OF NEWS MEDIA LANGUAGE ABOUT WELFARE REFORM AND RECIPIENTS FROM 1996 TO 2016

Year: 2020
Subjects: subject: Journalism

description: This study examined the language used by four mainstream newspapers to represent welfare recipients between 1996 and 2016. Using a mixed-method analysis developed on qualitative and quantitative analysis and guided by framing and critical discourse theories, this study investigated the words used by news media writers to describe welfare recipients following welfare reform in 1996 in the United States. My findings show that within some of the news media examined, stereotypical characterizations and values associated with the poor—dependency, lack of responsibility, and self-sufficiency—were used decades after the birth of the “welfare queen” trope, that quotes from welfare recipients were underrepresented in stories, and general coverage of welfare public assistance decreased during this time period. This study builds upon research of how welfare recipients were described in news media in the twentieth century and offers important implications for how journalists cover the poor in the current era.

description: Ordered electronic states have been extensively explored in cuprates and iron-based unconventional superconductors, but seldom observed in the epitaxial FeSe/SrTiO3(001) monolayer (FeSe/STO) with an enhanced superconducting transition temperature (Tc). Here, by using scanning tunneling microscopy/ spectroscopy (STM/STS), we reveal a checkerboard charge order in the epitaxial FeSe/STO monolayer, with a period of four times the inter-Fe-atom distance along two perpendicular directions of the Fe lattice. This ordered state is uniquely present in the superconducting FeSe/STO monolayer, even at liquid nitrogen temperature, but absent in the non-superconducting FeSe monolayer or bilayer. Quasiparticle interference (QPI) measurements further confirm it as a static order without an energy-dependent dispersion and gapped out within the superconductivity gap. The intensity of the charge order shows an enhancement near the superconducting transition temperature, thus implying a correlation with the high-Tc superconductivity in the FeSe/STO monolayer. This study provides a new basis for exploring the ordered electronic states and their interplay with high-Tc superconductivity in the FeSe monolayer.

description: Today, millions of older adults aged 65 and older, face the challenges of aging. In the past ten years, the number of people aged 65 and older in the U.S. increased from 37.2 million to 49.2 million, and by 2040 an estimated one in five Americans will be age 65 or older (Administration for Community Living & Administration on Aging, 2018; Urban Institute, 2014). Housing is a significant factor in health outcomes for this population because of their increased time spent in the home, which can put them at an increased risk for home accidents (Newman, 2003). Using the Health and Retirement Study, this study explores the association of assistive features being present in one’s home on health status and provides evidence to identify the housing needs of the older adult population.
Matchings in evolving graphs

description: Traditionally, the matching problem has been studied in settings where the entire graph is a priori available to the algorithm. Several practical applications such as internet ad allocation, ride sharing, and task allocation have motivated the study of this problem in models where the graph is revealed in parts or is undergoing modifications. In this thesis, we study the matching problem in such evolving graph models:1. Online Graphs with Bounded Recourse: In the online model, the graph, while fixed, is revealed to the algorithm adversarially, in the form of requests. The algorithm is required to respond to these requests immediately, and irrevocably. We study a variant of this model where the algorithm can revoke its decisions a bounded number of times. In this setting, we show upper and lower bounds on the recourse when the goal is to maintain an optimal matching.2. Dynamic Graphs: In the dynamic graph model, the graph is undergoing modifications in the form of edge insertions and deletions. The algorithm must adapt to these changes with the goal of minimizing the work done to reoptimize the solution. We study the matching problem in partially and fully dynamic settings, and obtain efficient algorithms which maintain close to optimal solutions.

description: Billions of dollars worth of losses are incurred due to corrosion and degradation of bridges in the United States. In a conventional bridge, deicing salts and chemicals cause rapid degradation in expansion joints, stiffeners, and other structural components. One of the solutions to tackle such a problem is to eliminate expansion joints in the system and design the whole bridge as an integral abutment bridge. In this type of bridge, the abutment and the deck act as a monolithic system. An integral abutment bridge has no expansion joints. Movement due to thermal expansion and contraction is accommodated by the abutments, which in turn transfer the movement to the piles. The maintenance costs of integral abutment bridges are considerably lower than the traditional jointed bridges; therefore, most state highway departments in the United States recommend the use of integral abutment bridges whenever possible. Using alternatives to conventional piling materials is another solution discussed in this thesis and will be the main focus of the same. Fiber Reinforced Polymer (FRP) piles have some advantages in corrosion resistance and hence can be economical in aggressive environments. In this thesis, FRP piles with octagonal cross-sections were analyzed for their behavior in integral abutment bridges. The octagonal section can easily be manufactured using a vast array of manufacturing methods, especially by the filament winding method, which is a cheaper manufacturing option as compared to other methods like pultrusion. Octagonal sections provide flat surfaces that make operations like bolting easy. In addition to this, irregular octagonal sections can provide stiffness and flexibility about two perpendicular axes simultaneously. Three-dimensional models were made and analyzed using ANSYS Workbench with the help of ANSYS Composite PrePost (ACP) modules. Over 300 soil-pile models were analyzed in this study. The results in this thesis depict the trends captured by varying different parameters for various soil-pile models.

Subjects: subject: Engineering

description: In wildland fires, the transport of firebrands is the main reason causing subsequent spot fires. The embers can travel farther than the fire itself and ignite the houses at the wildland urban interface (WUI). We consider previous experiments performed in a wind tunnel and used to characterize the transport of cold particles in a controlled velocity field that corresponds to a turbulent jet in a cross-flow. We perform numerical simulations of these experiments using the Fire Dynamics Simulator (FDS). The simulated jet and cross-wind velocity field are adjusted and tested to match the flow velocities measured in the experiments. The solid particles are simulated using the FDS Lagrangian model and our study includes comparisons between simulated and measured trajectories. The relationship between the particle flying pattern with the wind velocity field is examined.
D6.4 Final Report on the Project Impact

Subjects: Impact evaluation

description: This ARIADNEplus deliverable is the “Final Report on the Project Impact” completed in the last month of the project’s lifecycle. The evaluation of the project results covers all activities of the project. A common evaluation scheme for the impact of Integrating Activities does not exist, but ARIADNEplus developed a reporting framework that takes full account of the statements of expected impacts of the RI Programme and/or its section “Specific features for Research Infrastructures”, Part D. Chapter 2 comprises the summarised results of 11 areas of project activities, stated or implied by the expressed expectations of the RI Programme: • Extension of the stakeholder community • Supporting the FAIR data agenda in archaeology • Standardisation of archaeological datasets • Access to integrated knowledge-based resources • New services and virtual research environments (VREs) • Research infrastructures coordination • Cross-disciplinary fertilisation and sharing of resources • Innovation and partnership with industry • Use of services beyond research • TNA, training activities and resources • Dissemination and communication These activities have different weights, for example, Access to integrated knowledge-based resources comprises the whole ARIADNEplus Data Portal and integrated datasets, while Use of services beyond research is not a project priority, but nevertheless has been one of its ambitions. Chapter 3 outlines the framework. It describes in greater detail the Integrating Activity scheme, gives important background for the expected impact statements, briefly discusses the 10 statements, and references the sections which present the related activities and results achieved. Chapter 4 evaluates each of the 11 areas of project activities in detail.
