Publisher: name: Zenodo
Year: 2025

description: Diabetic Retinopathy (DR) is a serious complication caused by diabetes that affects the retina, leading to potential blindness if not treated early. This paper explores how deep learning models can be used to automatically detect and classify DR from retinal fundus images. The approach uses various con- volutionalneural networks (CNNs) including VGGNet, ResNet, and DenseNet, trained on large public datasets like Kaggle and MESSIDOR. The aim is to develop a reliable, efficient, and accurate system that supports early detection and clinical screening of DR, reducing the global burden of vision loss.

Publisher: name: Zenodo
Year: 2025

description: Medication adherence is a critical component of successful healthcare management, especially for patients with chronic conditions. However, non-adherence to prescribed medication regimens is a widespread issue, leading to poor health outcomes, increased hospitalizations, and higher healthcare costs. Traditional methods for monitoring and improving adherence have limitations, prompting the exploration of AI-driven solutions. This paper examines the role of AI-augmented systems in enhancing medication adherence through personalized support, real-time monitoring, and predictive analytics. We explore AI techniques such as machine learning, natural language processing, and predictive modeling to address the complex challenges associated with medication adherence. The paper highlights AI-powered mobile applications, virtual assistants, and wearable devices that can offer tailored adherence plans and behavioral interventions. Case studies and clinical implementations demonstrate the effectiveness of AI systems in improving adherence in patients with chronic diseases. Ethical, legal, and practical considerations in AI adoption for healthcare are discussed, with a focus on patient data privacy and integration challenges. The paper concludes by exploring future directions for AI in medication adherence, including personalized health systems and potential applications in global health. By leveraging AI, healthcare systems can overcome barriers to adherence, improve patient outcomes, and reduce the overall burden on the healthcare system.
Identifying the needs and future directions of seismic hazard for probabilistic infrastructure risk analysis

Year: 2015

description: The vulnerability of urban infrastructure to both ground shaking and geotechnical failure during large earthquakes has been demonstrated by recent earthquakes such as the 2010 - 2011 Canterbury earthquake sequence (New Zealand, 2010 - 2011) or 2010 Haiti event. Probabilistic seismic risk analysis to infrastructure systems requires the characterisation of both the transient shaking and permanent ground deformation elements of the hazard, and must do so incorporating both the aleatory and epistemic uncertainties and the spatial correlations and dependencies that are inherent in both of these aspects. Recent developments in characterisation of spatial correlation and cross-correlation in the ground motion uncertainties form the foundations of a comprehensive Monte Carlo-based methodology for analysis of seismic risk to spatially extended systems. New research directions are needed, however, in order to ensure that secondary hazard aspects are incorporated in the same way. These include the treatment of site amplification of the ground shaking, the modelling of permanent ground deformation from slope displacement and liquefaction, and permanent displacement due to coseismic slip on and around the fault rupture. Key considerations for integrated probabilistic framework for physically-realistic characterisation of the ground shaking and permanent ground displacement are illustrated using the example of simulation spatially correlated fault slip on an active fault rupture in a manner that can be integrated within a Monte Carlo-based probabilistic seismic hazard methodology.

description: This paper proposes a method for risk-based decision making for maintenance of deteriorating components, based on the partially observable Markov decision process (POMDP). Unlike most methods, the decision polices do not need to be stationary and can vary according to seasons and near the end of the lifetime. The approach is demonstrated through two examples, and the total expected costs are similar to those of another efficient method.

description: In order to assess the structural reliability and redundancy with respect to deterioration, it is required to select appropriate models which describe the deterioration process. The parameters associated with these models have to be estimated through statistical interference, which introduces uncertainties in parameter estimates. As the structural reliability indices which are incorporated in the reliability-based redundancy factor can be considered as random variable, this redundancy factor itself is a random variable as well. In case additional information becomes available, the distribution function can be updated by taking into account this extra information. In this contribution, a framework is developed, which allows for the incorporation of additional information in the uncertain reliability index and the associated redundancy factor through Bayesian updating. It is shown that in case additional information on a main variable is gathered, this has a significant effect on the (mean) value and uncertainty of the reliability index and the associated redundancy factor.

description: Das 21. Jahrhundert als "urban century" bietet neben vieler positiver Aspekte auch zahlreiche Herausforderungen im Stadtraum. Neben Stressfaktoren wie Lärm und Umweltverschmutzung nehmen Extremwetterereignisse wie Hitze und Starkregen zu, muss also eine Klimafolgenanpassung erfolgen und muss zusätzlicher Wohnraum für mehr Menschen geschaffen werden. Erholungs- und Aktivitätsräume stehen zudem in Konkurrenz zum Ausbau der Infrastruktur. Die Herausforderungen bedingen die Notwendigkeit für transdisziplinäre Diskurse und Arbeitsweisen im Rahmen einer klimawandelgerechten Stadtentwicklung. Mit diesem Hintergrund setzt sich die Arbeit zum Ziel Potenziale zu erarbeiten, die sich in Lüneburg für eine Begrünung der Innenstadt bieten, um dem sich wandelnden Klima zu begegnen, sowie herauszuarbeiten welche Akteuren, Schlüsselfaktoren und Schlüsselelemente die Umsetzung von Begrünungsmaßnahmen einschränken oder stärken. Mit der Methode der Konstellationsanalyse sollen zukunftsgerichtete und zentrale Handlungsfelder verdeutlicht werden. Es soll die Basis für eine erfolgreiche und nachhaltige Arbeitsweise sowie Zusammenarbeit im Bereich der Klimafolgenanpassung in Lüneburg gelegt werden.

description: Mit Blick auf eine Optimierung des Lüneburger Radroutennetzes wurde ein umfangreiches Maßnahmenpaket mit Handlungsempfehlungen zur Verbesserung des bestehenden Radverkehrsnetzes entwickelt und 2020 vom Verkehrsausschuss der Hansestadt Lüneburg die Einrichtung eines Fahrradstraßenrings beschlossen. Entschieden wurde die Umwidmung von Straßen, welche um die Fußgängerzone verlaufen, zu Fahrradstraßen, auf denen der Radverkehr Vorrang haben soll. Im Rahmen dieser Arbeit stellt der Stadtteil Rotes Feld den Untersuchungsraum dar. Die Barckhausenstraße, die durch den Stadtteil Rotes Feld führt, stellt einen möglichen Zubringer zum Fahrradstraßenring dar. Ziel dieser Arbeit ist es, die mögliche zukünftige Erweiterung des Fahrradstraßennetzes, das zurzeit lediglich aus dem geplanten Fahrradstraßenring besteht, in Richtung Süden durch die Umwidmung der Barckhausenstraße zur Fahrradstraße zu prüfen. Um die Eignung der Barckhausenstraße als Fahrradstraße zu überprüfen, wird zunächst in einem theoretischen Teil das Planungsinstrument "Fahrradstraße" vorgestellt. Dabei wird ein Überblick über die rechtlichen Rahmenbedingungen und das Einsatzfeld von Fahrradstraßen gegeben. In einem weiteren Abschnitt werden Maßnahmen erläutert, welche über die rechtlichen Voraussetzungen hinausgehen, sowie verschiedene in der Literatur ausgearbeitete Gestaltungsempfehlungen für eine Flankierung der Umwidmung wiedergegeben. Im Anschluss werden die bisherigen gesammelten praktischen Erfahrungen mit Fahrradstraßen in Deutschland beschrieben und die Gestaltung der Wallstraße, der ersten Lüneburger innerstädtischen Fahrradstraße, näher betrachtet. Im folgenden Teil werden der Arbeit zugrundeliegenden Methoden vorgestellt. Zu Beginn wird der Untersuchungsraum eingegrenzt. Danach folgt die Vorstellung der unterschiedlichen verwendeten Methoden zur Untersuchung des Verkehrs in der Barckhausenstraße. In der Folge werden die Ergebnisse der Untersuchungen dargestellt und die möglichen Einflüsse der gewählten Methodik auf die Ergebnisse und die Eignung der Barckhausenstraße als Fahrradstraße reflektiert. Im nächsten Abschnitt werden konkrete Umgestaltungsmaßnahmen für die Barckhausenstraße von der vorherigen Diskussion abgeleitet. Abschließend werden die wesentlichen Erkenntnisse zusammengefasst und ein Ausblick gegeben.

description: Ausgangspunkt der vorliegenden Bachelorarbeit ist der Zusammenhang einer (weiblich) vergeschlechtlichten Berufsgruppe im Sinne einer Gendered Profession und den politischen Programmen um mehr Männer in der Elementarpädagogik ist. Hierzu wird nicht die Legitimität der Forderung eines quantitativ höheren Anteils an Männern in der Elementarpädagogik erörtert. Vielmehr soll unter Zuhilfenahme eines wissenssoziologisch-diskursanalytischen Zugangs, durch die Analyse von audiovisuellen Daten der Kampagne "Vielfalt, MANN! Dein Talent für Hamburger Kitas", die Fragestellung untersucht werden, wie welche Konstruktionen zu Männlichkeit im Diskurs um mehr Männer in Berufsfeldern der Elementarpädagogik hervorgebracht werden. Zunächst skizziert die Arbeit den Forschungsstand über (diskursive) Hervorbringungsformen von Männlichkeit(en) im Kontext der Forderung nach mehr Männern in sozialen Berufen. Darauf aufbauend werden Forschungsdesiderate abgeleitet und anschließend verschiedene theoretische Konzepte zu Männlichkeit und Gender vorgeschlagen. Gewählt wurde: eine Perspektive auf Geschlecht als Strukturkategorie, habitustheoretische Perspektiven auf Männlichkeit, das Konzept der Hegemonialen Männlichkeit und Caring Masculinities sowie diskursanalytische Perspektiven auf Männlichkeit. Außerdem wird der Untersuchungsgegenstand als in vergeschlechtlichten Arbeitsmarktstrukturen und einer politischen Programmatik situierter kontextualisiert. Im nächsten Abschnitt wird das zugrundeliegende Studiendesign dargestellt und die Ergebnisse der Analyse herausgearbeitet. Identifiziert wurden drei programmatisch verschiedene Diskurse zu Männlichkeit, welche sich teilweise wiedersprechende Männlichkeitskonstruktionen (re-)produzieren. Es wurde (1) ein bürgerlicher Männlichkeitsdiskurs, (2) ein wissenschaftlich orientierter Männlichkeitsdiskurs und (3) ein Arbeitsmarktdiskurs analysiert. Abschließend findet unter der Beantwortung der Fragestellung eine Diskussion der Ergebnisse mitsamt Ausblick statt.
Fragility assessment of above ground petroleum storage tanks under storm surge

Publisher: name: The University of British Columbia
Year: 2015

description: Catastrophic failure of above ground storage tanks (ASTs) was observed due to storm surge during past hurricanes such as Katrina, Ike and Gustav causing severe environmental and economic impact. This paper evaluates the fragility of ASTs subject to hurricane storm surge to offer a basis for risk assessment of coastal facilities that store hazardous materials such as petroleum. Tank failures related to hurricane wind and earthquakes have been studied in literature; however, the effects of hurricane surge have not been addressed. Therefore, as a first step towards evaluating the fragility of ASTs under storm surge, this study identifies the primary modes of failure caused by storm surge—flotation and buckling. Next, uncertainties associated with each mode of failure are identified and characterized. The prime source of uncertainty considered for non-linear buckling analysis is geometric imperfections on the tank shell. Finally, these uncertainties are included while simulating response of ASTs during surge events. The results of these simulations are used to develop parameterized fragility curves using logistic regression. This methodology is applied to a typical tank from the Houston Ship Channel to assess conditional failure probability under storm surge. Key insights on dominance of the two modes of failure at different surge levels are also obtained. Using these observations, this study suggests structural and non-structural measures to prevent failure of tanks in future hurricane events. In addition, this paper provides a basis for parameterized fragility modeling of ASTs subject to hurricane storm surge that can be further extended to include other threats such as wave impact.

description: Thematischer Schwerpunkt dieser Arbeit ist die rechtliche Einordnung des Kinderrechtes auf Familienzusammenführung, welche ausgehend von den Kinderrechtskonventionen über europäisches Recht in nationales Recht mündet. Es werden Brüche in der Rechtsauslegung und Rechtsanwendung aufgezeigt, welche Familieneinheiten einschränken oder verhindern. Diesem gegenüber wird die Umsetzung der Kinderrechtskonventionen in nationales Recht in der Bundesrepublik Deutschland gestellt, um aufzuzeigen, dass Bestrebungen zur Umsetzung der Kinderrechtskonventionen auf nationaler Ebene vorhanden sind, diese jedoch gegen integrationspolitische Interessen im Sinne einer geordneten Zuwanderung ausgelegt werden. Um eine Brücke der intensiven rechtlichen Auseinandersetzung zu den Tätigkeitsrealitäten von Sozialarbeitern zu schlagen, werden weitergehend die Chancen und Herausforderungen für die Soziale Arbeit in der tatsächlichen Arbeitsrealität mit unbegleiteten, minderjährigen Ausländer betrachtet. Innerhalb dieses Kontextes wird dargestellt, dass das Arbeitsgebiet Flüchtlingssozialarbeit existent und aufgrund stetiger Zuwanderung in den Arbeitsrealitäten der Sozialen Arbeit allgegenwärtig ist. Hieraus ergeben sich Ausweitungen der Tätigkeitsgebiete Sozialer Arbeit, welchen mit einer Modifikation des Anforderungsprofils für Tätigkeiten in der Sozialen Arbeit mit Geflüchteten und einer verstärkten sozialpolitischen Einflussnahme begegnet werden muss.
Numerical description of size and load configuration effects in glulam structures

Publisher: name: The University of British Columbia
Year: 2015

description: The limit states design requires realistic strength values for the verification of reliable glulam structures. Here, the problem arises that the probabilistic system effect strongly affects load-carrying capacities. Considering this effect, modification factors for the glulam bending and tensile strength values are determined, based on strength simulations on various member sizes and structural systems. Using the proposed factors in the practical design of the treated problems leads to a structural reliability, which is more consistent, since the proposed factors cover the inherent system effects correspondingly.

description: This bachelor thesis aims to model the effect of the methods used within the Production Planning and Control (PPC) main task Production Program Planning on the logistical target values among the company's internal supply chain. Therefore, the basics of PPC and the Hanoverian Supply Chain Model are presented. The methods used to fulfill the PPC-tasks Sales Planning and Long Term Resource Planning are described precisely. By considering different conditions, the effects between these methods and logistical target values are modeled. These conditions form the initial point and unveil the impacts on the target values. The models show that the selection of adequate methods and the correct implementation have an immediate impact on the target values of the company's internal supply chain. The results of this bachelor thesis thus accentuate the effects as well as the importance of the methods used in the context of Production Program Planning and hence facilitate the handling of the PPC-Configuration in a practical environment.
description: Diese Bachelorarbeit hat das Ziel, die Wirkung der innerhalb der PPS-Hauptaufgabe Produktionsprogrammplanung verwendeten Verfahren auf die logistischen Zielgrößen der unternehmensinternen Lieferkette zu modellieren. Dafür werden zunächst die Grundlagen der Produktionsplanung und -steuerung (PPS) sowie das Hannoveraner Lieferkettenmodell (HaLiMo) dargelegt. Es werden die zur Erfüllung der PPS-Aufgaben Absatzplanung und langfristige auftragsanonyme Ressourcengrobplanung verwendeten Verfahren aufgegriffen und detailliert beschrieben. Anschließend werden die Wirkbeziehungen zwischen diesen Verfahren und den logistischen Zielgrößen modelliert, wobei verschiedene Fallbeispiele betrachtet werden, welche als Ausgangspunkt dienen und jeweils unterschiedliche Auswirkungen auf die Zielgrößen aufzeigen. Aus den Modellen geht hervor, dass die Auswahl geeigneter bzw. adäquater Verfahren sowie die richtige Durchführung dieser unmittelbar auf die Zielgrößen der unternehmensinternen Lieferkette einwirken. Die Ergebnisse dieser Bachelorarbeit akzentuieren somit die Auswirkungen sowie die Relevanz der im Rahmen der Produktionsprogrammplanung verwendeten Verfahren und erleichtern die Handhabung der PPS-Konfiguration in einem praxisnahen Umfeld.

description: Der menschengemachte Klimawandel und seine Folgen erfordern zügiges, entschlossenes und zielgerichtetes Handeln. Mit dem Pariser Klimaabkommen hat sich die Staatengemeinschaft zum Ziel gesetzt, die Klimaerwärmung bei 1,5°C zum vorindustriellen Niveau aufzuhalten. Deutschland hat daher beschlossen, bis 2050 klimaneutral zu werden. Die selbstgesteckten Zwischenziele werden jedoch verfehlt. Der überwiegend auf fossilen Energieträgern beruhende Verkehrssektor ist einer der wenigen Sektoren deren Emissionen steigen statt sinken. 95 % der Emissionen in diesem Sektor werden durch den Straßenverkehr emittiert. Insofern ist es relevant, die Verkehrsmittelwahl im Individualverkehr genauer zu betrachten. Das Auto ist – im Gegensatz zu Fuß-, Rad- und öffentlichem Personennahverkehr (ÖPNV) – positiv konnotiert mit „Fortschritt, Modernität und individueller Freiheit“. Zudem wird das Auto seit Jahrzehnten in unserer Gesellschaft finanziell und räumlich bevorzugt. Daraus sind Privilegien und Probleme erwachsen: unverhältnismäßige Raumnahme und die Degeneration des öffentlichen Raumes Verursachung von hohen externen Kosten, die nicht durch die Verursachenden sondern durch die gesamte Gesellschaft getragen werden, gesetzliche Bevorzugung sowie staatliche und kommunale Subventionen. Aufgrund dieser strukturellen Privilegierung ist es kaum möglich, eine Änderung des Mobilitätsverhaltens von Individuen zu erwarten, solange sich die Rahmenbedingungen nicht ändern.

description: In dieser Studie wurde untersucht, ab welcher Größe die statistische Effektstärke Cohen's d klinisch relevant wird. In einer durch halbstandardisierte Interviews ergänzten Online-Studie wurden den 69 Teilnehmern jeweils vier Szenarien gezeigt, in denen sich Zwillinge in ihren depressiven Beschwerden mit einem d = .5, .8, 1.1 oder 1.4 unterschiedlich stark voneinander unterschieden. Diese Effektstärken wurden durch unterschiedliche Testausprägungen im Depressivitätstest PHQ-9 generiert und lassen sich in Punktunterschiede in den Beschwerdebildern übertragen. Die Beschwerden der Zwillinge wurden jeweils auf Intervallskalen eingeschätzt. Die Zwillinge unterschieden sich zum einen im Ausmaß ihrer Beschwerden, zum anderen entschieden sie sich für unterschiedliche Behandlungsansätze, um Verbesserungen ihrer Beschwerden zu erzielen. Der eine Zwilling wählte eine Psychotherapie, der andere bevorzugte es, zu beobachten und abzuwarten. Eine rmANOVA zeigt, dass die Teilnehmer ab einer Effektstärke von d = .8 verlässlich unterscheiden können, welchem Zwilling es besser geht und in welchem Ausmaß. Diese Effektstärke entspricht einer Punktdifferenz im PHQ-9 von 5 Punkten. Die vorliegende Studie wagt einen ersten Versuch, die klinische Relevanz der Effektstärke Cohen's d durch subjektive Einschätzungen darzustellen und einen Schwellenwert zu identifizieren. Dieser kann in weiterführender Forschung näher untersucht, optimiert und weiterentwickelt werden.

description: The aim of this paper is to determine how a carbon footprint label for grocery products can be designed to facilitate a sustainable consumption behaviour. Therefore, a mixed-method approach was used consisting out of a review of relevant literature and an explorative quantitative survey with n=158 participants. It was found that consumers generally have a positive attitude towards carbon labelling, but they lack understanding of the term, its underlying concepts and the emissions caused by grocery products. In regard to the design criteria of a carbon label, labels with a coloured scale are preferred most by consumers. Also, the mechanisms of consumer behaviour imply that not all parts of the behaviour are visible and controllable for individuals themselves. The concluding concept proposal summarises important criteria of a carbon labelling system that has the goal to educate consumers and facilitate a lower carbon consumption behaviour, such as a simple visual design, the use of a colour scale, a design enabling a comparison, the provision of a link to further information, the public enforcement of the system and overall uniformity.

description: This article describes a two stage Reliability-Based Design Optimization (RBDO) algorithm. The first stage consists of solving an approximated RBDO problem using meta-models. In order to use gradient-based techniques, the sensitivity of failure probabilities are derived with respect to hyperparameters of random variables as well as, and this is a novelty, deterministic variables. The second stage focuses on the local refinement of the meta-models around the first stage solution using generalized “max-min” samples. The approach is demonstrated on three examples including a crashworthiness problem with 11 random variables and 10 probabilistic constraints.

description: Fusing predictions from multiple simulators in the early stages of the conceptual design of a wind turbine results in reduction in model uncertainty and risk mitigation. Aero-servo-elastic is a term that refers to the coupling of wind inflow, aerodynamics, structural dynamics and controls. Fusing the response data from multiple aero-servo-elastic simulators could provide better predictive ability than using any single simulator. The co-Kriging approach to fuse information from multifidelity aero-servo-elastic simulators is presented. We illustrate the co-Kriging approach to fuse the extreme flapwise bending moment at the blade root of a large wind turbine as a function of wind speed, turbulence and shear exponent in the presence of model uncertainty and non-stationary noise in the output. The extreme responses are obtained by two widely accepted numerical aero-servo-elastic simulators, FAST and BLADED. With limited high-fidelity response samples, the co-Kriging model produced notably accurate prediction of validation data.

description: This paper examines the prevalence of homelessness among families participating in the Head Start program in the United States. In conducting this study, data were collected from three sources. The first source was State and Metropolitan Area Data from the 2010 state-to state statistical census report. The second source of information was collected by the department of Health and Human Services, and the last source of information was state-to-state statistical data collected by the Head Start program. I analyze information from the United States Census report ranging from 2006, 2008, and 2009 relating to social conditions and environmental factors in the fifty United States, such as the number of adults in a state who have completed less than a high school education, and the number of families who are living slightly above and below the poverty line. Overall homelessness rates among Head Start participating families were low. However, regression analysis showed an unexpected inverse relationship between indicators of poverty in a state and the number of families and children in that state's Head Start program who experienced homelessness during the course of the enrollment year. These findings are discussed in light of Head Start's mission to help underserved children.

description: Many companies use sampling plans for the acceptance or rejection of lots of products. The final outcome of this decision-making process is based on the inspection of a sample of products selected from a lot under inspection, where a quality characteristic is observed. An important parameter of interest related to acceptance sampling for attributes is the proportion of defective items. This parameter is unknown for a given lot of products, but it can be estimated from the aforementioned sample information. Additional quality characteristics can be observed at the inspection stage. We propose to use this auxiliary information to obtain more accurate estimators of the lot fraction defective at the estimation stage. Various relevant applications of this process are described. For possible scenarios that may arise in practice, the empirical properties of the suggested estimation methods are investigated using Monte Carlo simulations, and desirable results are obtained when there is a strong relationship between the quality characteristic of interest and the auxiliary quality characteristic.

description: Wave energy converters (WECs), which harvest energy from the waves and transfer them to electricity, are a new technology, where structural standards need to be developed. An important step towards standardization is the calibration of partial safety factors. A methodology for calibration of partial safety factors for design of welded details for wave energy converter applications is presented in this paper using probabilistic methods. The paper presents an example with focus on the Wavestar device. SN curves and Rainflow counting are used to model fatigue without considering inspections. The influence of inspections is modelled using a fracture mechanics approach, which is calibrated by the SN curve approach. Furthermore, the paper assesses the influence of the inspection quality. The results show that with multiple inspections during the lifetime of the device and by applying a good inspection quality, the safety factor can be significantly reduced.

description: Research has shown that the African American community underuses professional mental health services and has generally more negative attitudes toward seeking help for mental health challenges than their European American counterparts. Stigma surrounding mental illness and the desire to keep challenges secret from others are two factors that have received much attention in the literature examining this phenomenon (Mishra, Lucksted, Gioia, Barnet, & Baquet, 2009; Thompson, Bazile, & Akbar, 2004; Larson & Chastain, 1990; Cramer, 1999). Further, social support has also been linked to help-seeking attitudes in the African American community, (Pickard, Inoue, Chadiha, & Johnson, 2011; Constantine, Wilton, & Caldwell, 2003). The current study assessed help-seeking attitudes, mental health stigma, self concealment, stigmatizing attitudes towards mental health and mentoring experience in 123 African American/Black college students. Mental health stigma, self-concealment, mentoring experience, and help-seeking attitudes demonstrated statistically significant bivariate correlations in expected directions. Further, a linear multiple regression analysis revealed stigma and self-concealment to be mediators in the relationship between mentoring and help-seeking attitudes. Finally, differences were discovered between mentoring type and mentoring experience. Students with both informal and formal mentors had the best mentoring experience in comparison to students with neither or informal mentor. Results from the current study further support the idea that mentoring relationships play a role in reducing stigma and self-concealment, which contribute to better help-seeking attitudes for African American college students. The importance of mentoring relationships to variables related to better well-being are discussed.

description: Abstract:The significance of back fat thickness (BFT) in pigs as a key indicator of nutritional status, metabolic health, reproductive performance, and overall well-being in commercial swine production. Utilizing advanced tools like ultrasound imaging, digital calipers, and computerized systems, producers can accurately assess and monitor BFT, facilitating targeted interventions to optimize feed efficiency, reproductive outcomes, and meat quality. BFT measurement is commonly performed at anatomical landmarks such as the last rib, last thoracic vertebra, and lumbar vertebrae, using techniques like ultrasound and calipers. The study highlights that balanced nutrition, feeding management, genetic selection, and health management are crucial for improving BFT. Moreover, optimal BFT plays a pivotal role in heat regulation, disease resistance, mobility, stress resilience, and production efficiency, directly influencing animal welfare and market competitiveness. By maintaining adequate BFT, farmers can enhance feed conversion ratios, reduce production costs, and achieve better meat quality, contributing to more sustainable and profitable swine farming practices.Key Words: Caliper, Swine production, Scanning, Ultrasound
Generation of synthetic accelerograms compatible with a set of design specifications

description: The research addressed here concerns the generation of seismic accelerograms compatible with a given response spectrum and with other design specifications. The time sampling of the stochastic accelerogram yields a time series represented by a random vector in high dimension. The probability density function (pdf) of this random vector is constructed using the Maximum Entropy (MaxEnt) principle under constraints defined by the available information. In this paper, a new algorithm, adapted to the high stochastic dimension, is proposed to identify the Lagrange multipliers introduced in the MaxEnt principle to take into account the constraints. This novel algorithm is based on (1) the minimization of an appropriate convex functional and (2) the construction of the probability distribution defined as the invariant measure of an Itô Stochastic Differential Equation in order to estimate the integrals in high dimension of the problem.
Environmental contours for determination of seismic design response spectra

description: This paper presents a procedure for using environmental contours and structural reliability design points for the purpose of deriving seismic design response spectra for use in structural engineering design checks. The proposed approach utilizes a vector-valued probabilistic seismic hazard analysis to characterize the multivariate distribution of spectral accelerations at multiple periods that may be seen at a given location, and a limit state function to predict failure of the considered system under a given level of shaking. A reliability assessment is then performed to identify the design point - the response spectrum with the highest probability of causing structural failure. This is proposed as the spectrum for which engineering design checks can be performed to evaluate performance of a given structure. While the full structural reliability analysis would not be performed in any practical application, this analysis does provide three major insights into appropriate response spectra to use in engineering evaluations. First, when the structure’s limit state function is dependent on a spectral acceleration at a single period, this approach produces risk-targeted spectral accelerations consistent with those recently adopted in several building codes. Second, the design point spectrum can be approximated by a Conditional Mean Spectrum (conditioned at the spectral period most closely related to the structure’s failure). This motivates recent proposals to use the Conditional Mean Spectrum for engineering design checks. Third, the design point spectrum will vary depending upon the structural limit state of interest, meaning that multiple Conditional Mean Spectra will be needed in practical analysis cases where multiple engineering checks are performed (though this can be avoided, at the expense of conservatism, by using a uniform risk spectrum). With the above three observations, this work thus adds theoretical support for several recent advances in seismic hazard characterization.

description: A probabilistic approach is necessary to estimate the magnitude of the braking force that compares in terms of return period with the vertical traffic loads present in bridge design codes. A data set from a Danish Field Operational Test served as support to identify hard braking episodes and to compute travelled distances by road hierarchy. The rate of braking events per vehicle travelled distance is used as estimate of the braking probability. Concurrently a structural model was developed for stochastic analysis of the dynamic response of bridges to braking events from realistic traffic configurations. This paper presents results for extreme braking forces on bridges with site-specific traffic data and within a probabilistic framework. Such evaluation is economically advantageous when compared to the application of structural codes, while still meeting the reliability targets they impose.

description: A relevant number of critical facilities, such as hospitals, schools and city halls, experienced extensive damage that resulted in loss of their functionality, and consequently huge economic losses and slow restoration processes after earthquakes. In some communities not well organized, the recovery process can last several years and the community or the system is never brought back to the initial functionality. The awareness that damage can not be avoided has increased the attention on designing buildings that are both safe and resilient, however it is often assumed that such design can increase costs to unacceptable levels. The paper compares life-cycle costs and resilience of respectively a hospital and a school which have been retrofitted using both a moment resisting frame system and a base isolated system. Performance-based earthquake evaluation tools are used to estimate the total cost of ownership, including expenses associated with initial construction, damage repair, loss of functionality and resilience. Numerical analyses have shown that resilience of both schools and hospitals can be improved by using a seismic isolation system that will also reduce life-cycle costs and downtime with respect to a conventional fixed-based design.
