description: In order to minimize the probability of foundation failure resulting from cyclic action on structures, researchers have developed various constitutive models to simulate the foundation response and soil interaction as a result of these complex cyclic loads. The efficiency and effectiveness of these model is majorly influenced by the cyclic constitutive parameters. Although a lot of research is being carried out on these relatively new models, little or no details exist in literature about the model based identification of the cyclic constitutive parameters. This could be attributed to the difficulties and complexities of the inverse modeling of such complex phenomena. A variety of optimization strategies are available for the solution of the sum of least-squares problems as usually done in the field of model calibration. However for the back analysis (calibration) of the soil response to oscillatory load functions, this paper gives insight into the model calibration challenges and also puts forward a method for the inverse modeling of cyclic loaded foundation response such that high quality solutions are obtained with minimum computational effort. Therefore model responses are produced which adequately describes what would otherwise be experienced in the laboratory or field.

The technological revolution, the Metaverse and Artificial Intelligence
Creators: name: Pira, Francesco
Publisher: name: Addiction & Social Media Communication

description: We have entered the era of the Metaverse and Artificial Intelligence that have undone the definitions that applied until recently, the separation of real and virtual, categories that no longer exist with the increasingly massive digitization of processes. In the age of the Metaverse and Artificial Intelligence everything takes on different contours and there are aspects that are still little known. Digitization as a process and the speed with which technology produces new tools have meant that never before as in this historical era have, we been inundated with an over-production of data that must be deciphered, interpreted and understood. This is an epochal change that affects society and especially people. The fragmentation of individual identity also depends on the power of technology in the modern world. So many people live parallel and virtual realities, even exploiting fake profiles on social media, and depend on technological tools on a daily basis. All connected and in fact increasingly alone. This makes clear the paradox that results from the materialization of social interaction processes that are the consequence of disintermediation, which puts the individual at the center, who does not govern the process but adapts to the environment. A second effect is that in such a context, the proliferation of information cascades, the ease with which fake news is relaunched through the web and persists in digital environments is a demonstration of how difficult it can be to identify them and how much more difficult it is to give rise to positive cultural and identity transformations capable of blocking polarizing drives and the shattering of social ties.

Subjects: Internet abuse; substance addiction; behavioral dependence; compulsion.

description: Internet abuse has been defined as 'addiction', as it shares behavioral, and also neurobiological aspects with other categories of dependencies. Similarities and differences between addictions with and without substances should be further investigated to avoid confusion in diagnostic criteria and intervention planning. This study aims to investigate whether internet abuse is related to overt substance addiction, if the presence of compulsive tendencies in personality traits can be considered a shared variable, and how different forms of abuse influence overall perceived well-being, taking into account also the level of Social Desirability. The Internet Addiction Test (IAT), the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), the State-anxiety, Depression, and the Maudsley Obsessional-Compulsive Questionnaire (MOCQ-R) drawn from the Cognitive Behavioral Assessment Battery, and the Short form of the Marlowe-Crowne Social Desirability Scale, were administered to a sample composed of 84 adult subjects, 43 diagnosed as addicted to substances and 43 non-addicted subjects, matched for gender and age. The results show that IAT scores are inversely correlated to the age of the subjects, but not linked with gender. As hypothesized, the control group shows higher levels of well-being, while the subjects diagnosed with substance addiction present higher levels of anxiety, depression, and higher compulsive scores, significantly correlated with depression. Higher levels of internet dependence are found in the non-diagnosed as addicted participants, suggesting caution in classifying dysregulated Internet behavior as 'addiction'.

description: Generations “Y” and “Z” have lived through great changes that have followed the development of the media, first, and then of social media. The digital revolution accompanied by the end of post-modern culture has attempted to defeat the myths, symbols, and rituals that had characterized the mirror in which individual and collective behaviors found meaning for millennia. The breaking of the generational pact with the consequent absence of a story to be able to elaborate on identity construction has led to a continuous construction of the self based not on “who I am” but on “how I should appear”. In this framework, time and space have lost their meaning and the Other has become a container of rewards without being recognized in its true identity. The absence of otherness has created a void and given birth to new pathological forms linked to immediacy or to “everything now and immediately”.

description: Over the last decade, the technology of constructing buildings has been dramatically developed especially with the huge growth of CAD tools that help in modeling buildings, bridges, roads and other construction objects. Often quality control and size accuracy in the factory or on construction site are based on manual measurements of discrete points. These measured points of the realized object or a part of it will be compared with the points of the corresponding CAD model to see whether and where the construction element fits into the respective CAD model. This process is very complicated and difficult even when using modern measuring technology. This is due to the complicated shape of the components, the large amount of manually detected measured data and the high cost of manual processing of measured values. However, by using a modern 3D scanner one gets information of the whole constructed object and one can make a complete comparison against the CAD model. It gives an idea about quality of objects on the whole. In this paper, we present a case study of controlling the quality of measurement during the constructing phase of a steel bridge by using 3D point cloud technology. Preliminary results show that an early detection of mismatching between real element and CAD model could save a lot of time, efforts and obviously expenses.

description: Introducing the Metaverse, Augmented, and Virtual Reality will change people's ways of life and daily gestures. Floridi, in this regard, has coined the term "mangrove society" to indicate the living conditions of human beings suspended between online and offline. In addition to changing lifestyle habits, introducing new technologies impacts many sectors of science, including psychology and treatments on psychological well-being, so much so that the term cyberpsychology has already been coined. Studies and research on these new systems are in their infancy and show potential future developments and the limits they contain, such as the phenomenon of cybersickness and the impact that the new tools could have on physical and mental health. Furthermore, with new technologies, privacy-related problems are arising, and in part have already occurred, which should be carefully evaluated and regulated.

description: Recently there has been a surge of interest in PDEs involving fractional derivatives in different fields of engineering. In this extended abstract we present some of the results developedin [3]. We compute the fundamental solution for the three-parameter fractional Laplace operator Δ by transforming the eigenfunction equation into an integral equation and applying the method of separation of variables. The obtained solutions are expressed in terms of Mittag-Leffer functions. For more details we refer the interested reader to [3] where it is also presented an operational approach based on the two Laplace transform.

description: Migration strategies are genetically inherited in most songbirds, and closely related species can exhibit markedly contrasting migration programs. Here, we investigate the autumn migration of one 'Helopsaltes' grasshopper-warbler from a population near Magadan, North East Russia, based on light-level geolocation. Although often considered to belong to Middendorff's Grasshopper-warbler 'H. ochotensis', recent genetic studies suggest that birds from this population are more closely related to Pallas's Grasshopper-warbler H. certhiola. We compare the migratory behavior of the Magadan bird with two Pallas's Grasshopper-warblers tracked from populations in the Kolyma River valley and the Amur region, Russia. We found similar migration patterns in all three tracked individuals, with stopover sites in eastern China and wintering sites in mainland Southeast Asia, within the known range for Pallas's Grasshopper-warbler. Furthermore, based on morphological data compiled during bird ringing, we were able to confirm the presence of potential "Magadan grasshopper-warblers" during spring and autumn migration in Thailand. Our scant data provide further evidence that Magadan 'Helopsaltes', notwithstanding their morphological resemblance to Middendorff's Grasshopper-warbler, constitute a population of Pallas's Grasshopper-warbler.

Towards quantifying the effect of aftershocks in seismic risk assessment
Creators: name: Jalayer, Fatemeh

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

description: The state of the art in seismic design and assessment of structures implicitly relies on structural redundancy in order to deal with the effect of the triggered sequence of aftershock events on a building. Calculating the time-dependent limit state exceedance probability for a structure considering both the main event and the triggered sequence of aftershocks is complicated both by the time-dependent rate of aftershock occurrence and also the cumulative damage caused by the sequence of events. Taking advantage of a methodology developed in previous works by the authors for post-mainshock risk assessment, the limit state probability due to a sequence of a mainshock and the triggered aftershocks is calculated herein. Moreover, a closed- and analytic-form approximation to the post-mainshock limit state probability given the mainshock magnitude is derived. This closed- and analytic formulation facilitates the estimation of the limit state probability by employing the standard tools in risk assessment such as the fragility curve for the intact structure. Applying the proposed methodology for a reinforced concrete (RC) concrete moment-resisting frame with infills subjected to the main event and the triggered sequence emphasizes the importance of taking into account the cumulative damage caused by the triggered sequence for the case-study model. Moreover, it is demonstrated that the proposed analytical approximation based on the fragility curve for the intact structure leads to a surprisingly close agreement with the best-estimate results obtained by considering the time- and event-dependent degradation in the structure.

description: Spatial variability is one of the most significant uncertainties in soil properties that affect the reliability of slope stability. It can be incorporated into slope reliability analysis and risk assessment through random finite element method (RFEM) in a rigorous manner. The great potential of RFEM in reliability analysis and risk assessment of soil slopes has been demonstrated in previous studies. Nevertheless, it often suffers from a common criticism of requiring extensive computational efforts and a lack of efficiency, particularly at small probability levels. This study develops an efficient RFEM that integrates RFEM with an advanced Monte Carlo Simulation method called “Subset Simulation (SS)”. By this means, the computational efficiency of calculating the failure probability and risk is significantly improved. This enhances the applications of RFEM in slope reliability analysis and risk assessment at small probability levels. In addition, the proposed SS-based RFEM also provides insights into the relative contributions of slope failure risk at different probability levels to the overall risk. Finally, the proposed approach is illustrated through a soil slope example. It is shown that the slope failure probability and risk can be evaluated properly using SS-based RFEM.

description: Polymer modification of mortar and concrete is a widely used technique in order to improve their durability properties. Hitherto, the main application fields of such materials are repair and restoration of buildings. However, due to the constant increment of service life requirements and the cost efficiency, polymer modified concrete (PCC) is also used for construction purposes. Therefore, there is a demand for studying the mechanical properties of PCC and entitative differences compared to conventional concrete (CC). It is significant to investigate whether all the assumed hypotheses and existing analytical formulations about CC are also valid for PCC. In the present study, analytical models available in the literature are evaluated. These models are used for estimating mechanical properties of concrete. The investigated property in this study is the modulus of elasticity, which is estimated with respect to the value of compressive strength. One existing database was extended and adapted for polymer-modified concrete mixtures along with their experimentally measured mechanical properties. Based on the indexed data a comparison between model predictions and experiments was conducted by calculation of forecast errors.

description: Three years after the World Health Organization (WHO) declared COVID-19 a pandemic, its impact remains profound and widespread (Cucinotta & Vanelli, 2020; Sohrabi et al., 2020). Originating in China, the virus rapidly disseminated globally, prompting a host of public health measures aimed at curbing its effects (Byttebier, 2022; Rabi et al., 2020; Rothan & Byrareddy, 2020). These measures included enhanced hand hygiene, social distancing, movement restrictions, and intensified screening processes. Despite these efforts, the pandemic has continued to inflict significant morbidity and mortality worldwide (Halperin et al., 2021; Huang et al., 2021; Mudenda et al., 2022; Piret & Boivin, 2021). This abstract provides an overview of the ongoing challenges posed by COVID-19 and the various strategies implemented to mitigate its impact, highlighting the persistent need for effective public health interventions and continued vigilance in the fight against the virus
Discretization of structural reliability problems : an application to runway overrun
Creators: name: Zwirglmaier, Kilian
name: Straub, Daniel
Publisher: name: The University of British Columbia
Year: 2015

description: Bayesian networks (BNs) are a powerful tool for efficiently representing joint probability distributions and updating probabilities in near real-time. We combine BNs with structural reliability concepts to develop a warning system for runway overrun of a landing aircraft, one of the most critical accident types in civil aviation. This warning system allows to use currently available measurements of the aircraft weight, the head wind and the approach speed to update the probability of runway overrun in-flight. Based on the probability, the system informs the pilots whether or not it is save to land. One of the key challenges when treating structural reliability problems in a discrete BN framework is the discretization of the continuous outcome space of the reliability problem. We apply a heuristic developed in Zwirglmaier and Straub (2014) to discretize the reliability problem, such that the discretization error is kept small with only a moderate number of discretization intervals.

description: The theory of regular quaternionic functions of a reduced quaternionic variable is a 3-dimensional generalization of complex analysis. The Moisil-Theodorescu system (MTS) is a regularity condition for such functions depending on the radius vector r = ix+jy+kz seen as a reduced quaternionic variable. The analogues of the main theorems of complex analysis for the MTS in quaternion forms are established: Cauchy, Cauchy integral formula, Taylor and Laurent series, approximation theorems and Cauchy type integral properties. The analogues of positive powers (inner spherical monogenics) are investigated: the set of recurrence formulas between the inner spherical monogenics and the explicit formulas are established. Some applications of the regular function in the elasticity theory and hydrodynamics are given.

title: Share trading and product innovation: evidence from Chinese listed manufacturing firms
Creators: name: Changhong, Han
Publisher: name: University of Reading
Year: 2024

description: This study investigates whether and how boards of directors of Chinese listed 
manufacturing firms utilise different share trading types as mechanisms for their firms’ product 
innovation by employing in-depth interviews targeting board members of 25 listed manufacturing
firms in China from December 2021 to June 2022. The data analysis revealed that innovation, in 
general, and product innovation, in particular, plays a critical role to these firms’ survival and 
growth. Despite the variation in innovation investment across firms because of the impact of firms’
specific factors determined by their unique internal and external environment regarding 
contingency theory, the innovation investment is still much lower than in developed countries with 
less than 10% of total revenues. These firms have implemented share buyback, M&As, including 
stock for stock mergers, and seasonal equity offerings, but they have not engaged with insider 
trading recently because of their concerns with this practice’s legal liabilities and consequences on 
firms’ survival. These firms have mostly carried out share buyback for equity incentive 
programmes and for addressing the stock split problems instead of signalling, manipulating, 
investing, compensating shareholders, or other purposes. Share buyback practice has not been
utilised as a direct mechanism for product innovation, but it has indirectly improved product 
innovation through the incentive programme that mitigates agency conflicts, and thus improves 
the management’s performance, including the R&D team members’ performance. These firms
have also implemented M&A and SEOs to boost innovation, but the degree to which M&A and 
SEOs was used to support innovation is still limited. These firms have mostly used M&A to 
acquire innovation capabilities abroad and only issued additional shares to raise funds for product 
innovation when other sources of funds are unavailable. This study offers several significant
contributions to both theory and practice.

Life-cycle robustness : quantification and challenges

name: Bergmeister, Konrad
Publisher: name: The University of British Columbia
Year: 2015

description: Life-cycle robustness is achieved when a structural member or a system is designed to maintain its intended function and required safety level within its desired life-cycle. The different character of effects that each element of the system needs to undergo (damage, ageing, extreme events, changes in usage) in conjunction with the diversity in the intrinsic material properties, form a demanding problem. Further complexity emerges when one realizes that time is not simply a variable, but a factor permeating model choices and uncertainty representation approaches. Different effects in the load side, and properties in the resistance side develop differently in time. Depending on the scale of the problem, the spatial randomness of materials such as concrete may be relevant for the accurate quantification of failure probabilities, and may require careful modelling, even at a mesoscale. For a long-term analysis, where the influence of uncertainties may dominate over predictability, robust design concepts and analyses methods that are relatively insensitive to small variations in variable inputs related to secondary effects and processes can prove decisive. On the computational side, challenges are associated with the computational cost of simulations and nonlinear analyses required to determine time-variable reliability profiles, considering all likely scenarios. Furthermore, statistical characteristics of the inputs, in particular their tail behaviour and their statistical dependence, needs to be properly captured and reproduced while maintaining sufficiently small sample size, and thus acceptable computational cost. Within this contribution, a framework for the quantification of life-cycle robustness is presented in the context of fasteners subjected to sustained load and extreme events. The emerging challenges are presented and briefly discussed.

description: In construction engineering, a schedule’s input data, which is usually not exactly known in the planning phase, is considered deterministic when generating the schedule. As a result, construction schedules become unreliable and deadlines are often not met. While the optimization of construction schedules with respect to costs and makespan has been a matter of research in the past decades, the optimization of the robustness of construction schedules has received little attention. In this paper, the effects of uncertainties inherent to the input data of construction schedules are discussed. Possibilities are investigated to improve the reliability of construction schedules by considering alternative processes for certain tasks and by identifying the combination of processes generating the most robust schedule with respect to the makespan of a construction project.

Data Visualization via Enhanced Maps in a Digital Humanities Context – a Design Perspective
Creators: name: Huurdeman, Hugo C.
Publisher: name: Zenodo
Year: 2024

description: Abstract: In the past decades, geographical maps have been used extensively as a means for spatial data visualization in the Humanities and beyond. Here, we consider data visualization to be the representation as well as presentation of data for enhancing understanding. While maps have myriad advantages for visualization, such as presenting the spatial distribution of data to potentially generate new insights, they are also are inherently abstractions of reality. This abstraction can raise issues, particularly in the context of complex and multifaceted historical datasets fraught with uncertainty. This paper conceptually discusses these issues from a design perspective in the context of DH, specifically looking at cartographic design, interaction design and data structure. Subsequently, it briefly reveals how these angles were addressed in an enhanced 2D geographical maps viewer created within the Virtual Interiors project (2018-2022), which displays spatio-temporal historical datasets.

Integrated multi-hazard framework for the fragility analysis of roadway bridges
Creators: name: Gehl, Pierre
name: D’Ayala, Dina
Publisher: name: The University of British Columbia
Year: 2015

description: This paper presents a method for the development of bridge fragility functions that are able to account for the cumulated impact of different hazard types, namely earthquakes, ground failures and fluvial floods. After identifying which loading mechanisms are affecting which bridge components, specific damage-dependent component fragility curves are derived. The definition of the global damage states at system level through a fault-tree analysis is coupled with a Bayesian Network formulation in order to account for the correlation structure between failure events. Fragility functions for four system damage states are finally derived as a function of flow discharge Q (for floods) and peak ground acceleration PGA (for earthquakes and ground failures): the results are able to represent specific failure configurations that can be linked to functionality levels or repair durations.

description: Performing parameter identification prior to numerical simulation is an essential task in geotechnical engineering. However, it has to be kept in mind that the accuracy of the obtained parameter is closely related to the chosen experimental setup, such as the number of sensors as well as their location. A well considered position of sensors can increase the quality of the measurement and to reduce the number of monitoring points. This Paper illustrates this concept by means of a loading device that is used to identify the stiffness and permeability of soft clays. With an initial setup of the measurement devices the pore water pressure and the vertical displacements are recorded and used to identify the afore mentioned parameters. Starting from these identified parameters, the optimal measurement setup is investigated with a method based on global sensitivity analysis. This method shows an optimal sensor location assuming three sensors for each measured quantity, and the results are discussed.

description: It is well-known that the solution of the fundamental equations of linear elasticity for a homogeneous isotropic material in plane stress and strain state cases can be equivalently reduced to the solution of a biharmonic equation. The discrete version of the Theorem of Goursat is used to describe the solution of the discrete biharmonic equation by the help of two discrete holomorphic functions. In order to obtain a Taylor expansion of discrete holomorphic functions we introduce a basis of discrete polynomials which fulfill the so-called Appell property with respect to the discrete adjoint Cauchy-Riemann operator. All these steps are very important in the field of fracture mechanics, where stress and displacement fields in the neighborhood of singularities caused by cracks and notches have to be calculated with high accuracy. Using the sum representation of holomorphic functions it seems possible to reproduce the order of singularity and to determine important mechanical characteristics.

Applications of dynamic trees to sensitivity analysis
Creators: name: Becker, William
Publisher: name: The University of British Columbia

description: A recent approach to surrogate modelling, called dynamic trees, uses regression trees to partition the input space, and fits simple constant or linear models in each “leaf” (region of the input space). This article aims to investigate the applicability of dynamic trees in sensitivity analysis, in particular on high dimensional problems at low sample size, to see whether they can be applied to dimensionalities usually out of the range of surrogate models. Comparisons are made with Gaussian processes, as well as three measures based on a radial sampling scheme: the Monte Carlo estimator of the total sensitivity index, an elementary effects measure, and a derivative-based sensitivity measure. The results show that the radial sampling measures generally outperform the surrogate models tested here, with the exception of response surfaces that feature discontinuities.

description: Sensor faults can affect the dependability and the accuracy of structural health monitoring (SHM) systems. Recent studies demonstrate that artificial neural networks can be used to detect sensor faults. In this paper, decentralized artificial neural networks (ANNs) are applied for autonomous sensor fault detection. On each sensor node of a wireless SHM system, an ANN is implemented to measure and to process structural response data. Structural response data is predicted by each sensor node based on correlations between adjacent sensor nodes and on redundancies inherent in the SHM system. Evaluating the deviations (or residuals) between measured and predicted data, sensor faults are autonomously detected by the wireless sensor nodes in a fully decentralized manner. A prototype SHM system implemented in this study, which is capable of decentralized autonomous sensor fault detection, is validated in laboratory experiments through simulated sensor faults. Several topologies and modes of operation of the embedded ANNs are investigated with respect to the dependability and the accuracy of the fault detection approach. In conclusion, the prototype SHM system is able to accurately detect sensor faults, demonstrating that neural networks, processing decentralized structural response data, facilitate autonomous fault detection, thus increasing the dependability and the accuracy of structural health monitoring systems.

description: Abstract Over the past decades, technology has made a significant contribution to the development of education and has had a profound effect on school education in India. The Government of India has placed appropriate emphasis on Education (ET) technology in successive national education policies. Until 2019, Edtech did not attract enough funding, but the Covid-19 epidemic accelerated online learning and gave birth to a few EdTech startups in India and around the world. These Edtech companies have been around for almost two decades and promised a bright future in education. It is believed that education is one of the main sources of prosperity for millions of people living in Asian countries. However, the main method of delivery did not change fundamentally in the long run. Although some institutions have begun to use digital technology, the education sector is slow to embrace and implement the new age technology in its system. The same was true on the basis that the digital education system could eliminate the jobs of a few teachers, at least in school education. This current study aims to map out the current state of EdTech in India and their prospects. The current study also examines the strengths, weaknesses, opportunities, and challenges (SWOC) linked to Edtech companies after covid-19.

description: Over the last decade, there has been a steady increase in HIV-1 prevalence in Mizoram, India. Importantly, this increase in HIV-1 prevalence is not only limited to the key population groups such as female sex workers (FSWs) or people who inject drugs (PWID), and has been witnessed in general population as well. Injecting drug use has long been one of the key drivers of HIV-1 epidemic across the north-eastern states of India. In this study, using HIV-1 pol gene region sequences from Aizawl and adjoining districts, we examined the HIV-1 subtypes, recombinant forms, drug resistance mutations and also the spatiotemporal dynamics of the potential unique recombinant forms. In our dataset, the dominant subtype was HIV-1 subtype C (94.91%). We could also identify the presence of CRF01_AE (1.69%) and BC recombinant forms (3.39%). Drug resistance mutation analysis revealed that resistance against non-nucleoside reverse transcriptase inhibitors was most common in the sequences having any resistance mutations. Evolutionary analysis of unique BC recombinants estimated the most recent common ancestor of these sequences around 2004–2005 and them having an ancestry of United States of America (USA) origin.
