Publisher: name: Zenodo
Year: 2025

description: The global shift toward digital education has highlighted the urgent need for personalized learning solutions that accommodate diverse linguistic and cultural backgrounds. In multilingual education systems, where learners often face barriers related to language proficiency and curriculum accessibility, Artificial Intelligence (AI) has emerged as a transformative force. By leveraging machine learning, natural language processing, and adaptive learning algorithms, AI can design individualized learning pathways tailored to each student's language skills, cognitive preferences, and academic goals. This paper explores the foundational technologies behind AI-driven personalization in e-learning, focusing on content recommendation, real-time translation, and learning analytics. It presents use cases in formal education, adult learning, and inclusive education for marginalized linguistic communities. Case studies from global platforms and regional initiatives illustrate the effectiveness of AI in bridging language gaps and improving learning outcomes. Ethical considerations such as algorithmic bias, data privacy, and equity are critically examined. The paper also identifies challenges including limited language resources, contextual understanding, and integration with existing educational systems. Future directions include AI-supported multilingual tutoring, cross-cultural pedagogy, and low-resource language inclusion. AI-powered personalization promises a future where learners from diverse linguistic backgrounds can access

description: This paper proposes a mode-in-state contribution factor for a class of nonlinear dynamical systems by utilizing spectral properties of the Koopman operator and sensitivity analysis. Using eigenfunctions of the Koopman operator for a target nonlinear system, we show that the relative contribution between modes and state variables can be quantified beyond a linear regime, where the nonlinearity of the system is taken into consideration. The proposed contribution factor is applied to the numerical analysis of large-signal simulations for an interconnected AC/multi-terminal DC power system.

description: Abstract

Calotropis (Asclepiadaceae) often known as “madar” is an important medicinal plant. The current investigation includes the Phytochemical and Antimicrobial study of Calotropis species.

Solvent such as methanol, butanol, acetone, pet ether, chloroform and water were used. The antimicrobial study executed by agar well diffusion technique.

Alkaloids, flavonoids, tannins, saponins, phenols, and terpenoids are found in both plants according to phytochemical study. For antibacterial investigation Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa were used. The susceptibility of bacterial strains against different solvent extracts was tested using the agar well diffusion method.

Butanol and methanol extracts have better antibacterial activity than other extract because their zones of inhibition are larger.

Keywords: Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Agar well diffusion method, etc.

Propagation of uncertainties modelled by parametric p-boxes using sparse Polynomial Chaos Expansions
Creators: name: Schöbi, Roland

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

description: Advanced simulations, such as finite element methods, are routinely used to model the behaviour of physical systems and processes. At the same time, awareness is growing on concepts of structural reliability and robust design. This makes efficient quantification and propagation of uncertainties in computation models a key challenge. For this purpose, surrogate models, and especially Polynomial Chaos Expansions (PCE), have been used intensively in the last decade. In this paper we combine PCE and probability-boxes (p-boxes), which describe a mix of aleatory and epistemic uncertainty. In particular, parametric p-boxes allow for separation of the latter uncertainties in the input space. The introduction of an augmented input space in PCE leads to a new uncertainty propagation algorithm for p-boxes. The proposed algorithm is illustrated with two applications: a benchmark analytical function and a realistic truss structure. The results show that the proposed algorithm is capable of predicting the p-box of the response quantity extremely efficiently compared to double-loop Monte Carlo simulation.

description: Localized electrons subject to applied magnetic fields can restart to propagate freely through the lattice in delocalized magnetic Bloch states (MBSs) when the lattice periodicity is commensurate with the magnetic length. Twisted graphene superlattices with moiré wavelength tunability enable experimental access to the unique delocalization in a controllable fashion. Here we report the observation and characterization of high-temperature Brown-Zak (BZ) oscillations which come in two types, 1/B and B periodicity, originating from the generation of integer and fractional MBSs, in the twisted bilayer and trilayer graphene superlattices, respectively. Coexisting periodic-in-1/B oscillations assigned to different moiré wavelengths, are dramatically observed in small-angle twisted bilayer graphene, which may arise from angle-disorder-induced in-plane heteromoiré superlattices. Moreover, the vertical stacking of heteromoiré supercells in double-twisted trilayer graphene results in a mega-sized superlattice. The exotic superlattice contributes to the periodic-in-B oscillation and dominates the magnetic Bloch transport.

Tuning of record-based stochastic ground motion models for hazard-compatibility and applications to seismic risk assessment

Publisher: name: The University of British Columbia

description: This paper discusses the tuning of stochastic ground motion models so that compatibility of the resultant hazard with Ground Motion Prediction Equations (GMPEs) is directly established. This is facilitated by proper optimization for the predictive relationships involved in such models that relate seismicity characteristics to the model parameters. A computationally efficient approach is discussed that can seamlessly provide ground motions that match any chosen GMPE for any desired set of seismicity characteristics or structural periods. Foundation of the methodology is the development of a metamodel that facilitates a simplified relationship between the ground motion model parameters and its median predictions. This metamodel is subsequently used to efficiently select the predictive relationships that optimize the match to the chosen GMPE with the numerical accuracy of the metamodel predictions also explicitly incorporated in this optimization. The implementation of the tuned model within seismic risk assessment is also demonstrated.

description: Sickle cell disease (SCD) primarily affects people of African American descent in the United States. Many individuals do not know their sickle cell trait (SCT) status or might not be aware of SCD. The purpose of this study was to assess SCD knowledge, awareness of SCT status, and its impact on relationships. A cross-sectional study was conducted from August 2018 to June 2019 among students at a Historically Black College and University. Logistic regression was utilized to determine if the student’s SCD knowledge and SCT status had a significant impact on the student’s choice of relationships. A total of 203 students participated in the study. Most were female (60.1%) and African American (84.7%). The proportion of correct responses on individual questions within a SCD knowledge assessment ranged from 55.2% to 90.6%. Health professional students (Adjusted OR = 4.47; 95% CI = 1.18, 16.96; p = 0.028) and those with SCT (Adjusted OR = 13.00; 95% CI = 1.72, 98.39; p = 0.013) reported that their potential partner’s SCT status would have an impact on their current and future relationships. A large number of students are not knowledgeable about SCD and few are aware of their SCT status.

description: In the preceding papers, imposing certain complicated and strong conditions, the present author showed that the solution to the BCS-Bogoliubov gap equation in superconductivity is twice differentiable only on the neighborhoods of absolute zero temperature and the transition temperature so as to show that the phase transition is of the second order from the viewpoint of operator theory. Instead, we impose a certain simple and weak condition in this paper, and show that there is a unique nonnegative solution and that the solution is indeed twice differentiable on a closed interval from a certain positive temperature to the transition temperature as well as pointing out several properties of the solution. We then give another operator-theoretical proof for the second-order phase transition in the BCS-Bogoliubov model. Since the thermodynamic potential has the squared solution in its form, we deal with the squared BCS-Bogoliubov gap equation. Here, the potential in the BCS-Bogoliubov gap equation is a function and need not be a constant.

Creators: name: Researchscholar
Publisher: name: Zenodo
Year: 2025

description: The rapid urbanization and population growth of the 21st century have led to a significant increase in solid waste generation, placing immense pressure on municipal waste management systems. Traditional waste handling methods often lack efficiency, transparency, and scalability, resulting in environmental degradation, public health hazards, and economic losses. The integration of Artificial Intelligence (AI) and Computer Vision in waste management offers transformative solutions that optimize waste collection, automate sorting, and support data-driven policy decisions. This paper explores the technological foundations of smart waste management systems, focusing on AI algorithms for waste classification, object detection, route optimization, and behavior prediction. It highlights key use cases including intelligent waste bins, automated recycling facilities, and municipal fleet management. Real-world case studies demonstrate the effectiveness of AI-powered waste infrastructure in enhancing sustainability and operational efficiency. Ethical considerations such as data privacy, job displacement, and environmental justice are also critically analyzed. The paper concludes by addressing the challenges of infrastructure readiness, model generalizability, and public participation, while also examining future directions in edge computing, IoT integration, and circular economy analytics. Smart waste management powered by AI and computer vision holds the potential to build cleaner, greener, and more resilient urban ecosystems.

description: Background: Sickle cell disease (SCD) is prevalent in Saudi Arabia. This study evaluates the long-term survival rates of a cohort of SCD patients. Methods: This observational cohort study was conducted at King Saud University Medical City from January 2009 to September 2023. We enrolled 223 SCD patients between 2009 and 2014, collecting comprehensive data at baseline and during follow-up. The primary endpoint was overall survival. Results: The cohort had a median follow-up of 11.5 years, totaling 2,118 patient-years. The recent median age was 28.9 years (12.2–63.8). The survival rates at ages 20, 30, 40, and 50 years were 100%, 98.4%, 95.1%, and 89.0%, respectively, with no mortality observed before the age of 20 years. The incidence of mortality was 0.28 deaths per 100 patient-years. Among the six deaths (2.7%), causes included non-Hodgkin lymphoma, acute chest syndrome, and a sepsis-like condition, with three unknown causes. The median age of death was 36.3 years. The increased use of hydroxyurea, from 47% to 80%, was associated with reduced pain crises and acute chest syndrome, and improved hemoglobin and HbF levels. Of the patients, 43 (19.2%) were lost to follow-up, 16 (7.2%) were referred for stem cell transplant, and 16 (7.2%) were followed at other institutions. Conclusions: This study highlights excellent survival rates for SCD patients in our cohort. Nonetheless, the considerable loss to follow-up highlights the need for strategies to address this issue and larger multicenter studies to confirm our results.

Stochastic multi-scale finite element analysis for laminated composite plates
Creators: name: Zhou, Xiao-Yi
name: Gosling, Peter D.
Publisher: name: The University of British Columbia
Year: 2015

description: This paper proposes a dual stochastic finite element method for conducting stochastic analysis for laminated composite plates with consideration of microscopic material property uncertainties. A stochastic multiscale finite element method, which couples the multiscale computation homogenization method with the second order perturbation technique, is developed first to propagate variability in the effective elasticity property of composite arising from microscopic uncertainties such as Young’s modulus and Poisson’s ratio of constituent materials. Then a standard stochastic finite element analysis is conducted to consider structural level uncertainties. The performance of the proposed approach is evaluated by comparing the estimates of mean values and coefficients of variation for the effective elastic properties and structural response for a laminated composite plate with corresponding results from the Monte Carlo simulation method.

description: We initiate the study of software watermarking against quantum adversaries. A quantum adversary generates a quantum state as a pirate software that potentially removes an embedded message from a classical marked software. Extracting an embedded message from quantum pirate software is difficult since measurement could irreversibly alter the quantum state. In this work, we define secure watermarking PRFs for quantum adversaries (unremovability against quantum adversaries). We also present two watermarking PRFs as follows. - We construct a privately extractable watermarking PRF against quantum adversaries from the quantum hardness of the learning with errors (LWE) problem. The marking and extraction algorithms use a public parameter and a private extraction key, respectively. The watermarking PRF is unremovable even if adversaries have (the public parameter and) access to the extraction oracle, which returns a result of extraction for a queried quantum circuit. - We construct a publicly extractable watermarking PRF against quantum adversaries from indistinguishability obfuscation (IO) and the quantum hardness of the LWE problem. The marking and extraction algorithms use a public parameter and a public extraction key, respectively. The watermarking PRF is unremovable even if adversaries have the extraction key (and the public parameter). We develop a quantum extraction technique to extract information (a classical string) from a quantum state without destroying the state too much. We also introduce the notion of extraction-less watermarking PRFs as a crucial building block to achieve the results above by combining the tool with our quantum extraction technique.

description: We present a physically motivated formula for estimating the nuclear radius based solelyon fundamental constants. The model derives the nuclear radius as a scaled projectionof an electromagnetic confinement limit—defined as the minimum spatial curvature radiusspacetime can sustain for electromagnetic energy. By combining the Bohr radius (as anatomic-scale reference), the fine-structure constant (as a measure of EM field strength), andgeometric scaling 1/3 with proton number Z, we obtain a compact expression that predictsnuclear sizes with reasonable accuracy across the periodic table.

While the model does not account for nuclear binding energy variations, shell effects, orneutron excess, it provides a universal geometric and electromagnetic baseline for nuclearsize. It may serve as a first-principles lower-bound estimator in many cases, thoughoccasional overestimation indicate that it is best interpreted as a natural scale floor ratherthan a strict minimum.

description: The vibration control of complicated mechanical structures is impossible without proper mathematical models that allow to have a true apprehension of events occurring in structural member before the starting of the experiment and correct the diagnostic experiment in case of need. An approach that implies using of a discrete model reflecting all required features of a prototype system and permitting of an effective analytical and numerical investigation is proposed in the work. At first a discrete model of a bladed disk with flaw is considered. Taking into account the symmetry of the structure by utilization of mathematical tools of group presentation theory the number of degrees of freedom of the system is diminished. Small damage of the disk is regarded as perturbation of structure symmetry. The distinction of vibration characteristics such as natural frequencies and mode shapes of damaged and undamaged systems is determined theoretically with the help of perturbation theory and can be used as an effective diagnostic criterion of a small-scale damage of the structure. In the second part of the work a non-linear two-mass model of an acoustic emission in a damaged structure is proposed. On basis of the numerical integration of the nonlinear differential equations and expansion of the derived solution into a Fourier series free and forced vibrations of the model are investigated. It is shown that proposed model reflects all characteristic properties of vibrations of damaged structures: reduction of natural frequency, sub- and super-resonances, acoustic effects.

Year: 2015

description: This paper investigates the variability of the primary time independent components of the design wind load formulation. It is shown that the variability of these components has a significant influence on the total reliability of wind loads. The use of comparative studies of international wind load standards as an indicator of the variability of the time independent wind load components is discussed. A two part comparative study is done to determine the variability. It is found that the existing representative probability model of wind load components underestimates even a lower limit estimate of the variability of these components, particularly for pressure coefficients. Furthermore, insight is gained into the effects of various structural and wind load parameters on the total variability of wind loads.

description: Active contour models have achieved prominent success in the area of image segmentation, allowing complex objects to be segmented from the background for further analysis. Existing models can be divided into region-based active contour models and edge-based active contour models. However, both models use direct image data to achieve segmentation and face many challenging problems in terms of the initial contour position, noise sensitivity, local minima and inefficiency owing to the in-homogeneity of image intensities. The saliency map of an image changes the image representation, making it more visual and meaningful. In this study, we propose a novel model that uses the advantages of a saliency map with local image information (LIF) and overcomes the drawbacks of previous models. The proposed model is driven by a saliency map of an image and the local image information to enhance the progress of the active contour models. In this model, the saliency map of an image is first computed to find the saliency driven local fitting energy. Then, the saliency-driven local fitting energy is combined with the LIF model, resulting in a final novel energy functional. This final energy functional is formulated through a level set formulation, and regulation terms are added to evolve the contour more precisely across the object boundaries. The quality of the proposed method was verified on different synthetic images, real images and publicly available datasets, including medical images. The image segmentation results, and quantitative comparisons confirmed the contour initialization independence, noise insensitivity, and superior segmentation accuracy of the proposed model in comparison to the other segmentation models.

description: We study the scattering of certain non-linear dispersive partial differential equations (PDEs). We may interpret a solution to such a PDE as a model starting off at a given initial state and being evolved according to the PDE. In a linear setting, such a model would disperse its energy across physical space as it evolves in time. We investigate settings for the initial state such that the (oftentimes difficult to understand) nonlinear evolution of the model in fact displays this linear behaviour after a large amount of time.

The Dog That Didn’t Bark: Realism and the Question of Preventive War in 1905-1906 Wilhelmine Germany

description: Structuralist theories of international relations attempt to source state behavior in the polarity of the international system. This research paper seeks a structuralist answer to why Germany did not seek continental hegemony in 1905 when it enjoyed a decisive advantage in power and instead waited to go to war in 1914 when it faced a relatively unfavorable balance of power. Offensive realist theories struggle with this case because, according to this school of thought, security and continental hegemony are interchangeable and thus there is no reason offensive realists can point to as to why a Franco-German war should not have broken out in 1905 (Mearsheimer 2014, 259). Previous scholarship on the subject has shown that some if not all of the Kaiser’s key military and foreign policy advisors desired a preventive war in 1905 but were thwarted by Wilhelm’s intransigence (Lambi [1984] 2019, 251-252). This paper uses archival sources to reconstruct the views of key foreign policy decision-makers in order to attempt to understand why war was not launched. Ultimately, it concludes that elites in Germany did not seek hegemony and that the Kaiser vetoed plans for preventive war because of concerns about British naval retaliation, out of concerns that attacking France would lead to a balancing coalition between the UK, Italy, and the Ottoman Empire, and because a Franco-German war might trigger a socialist insurrection on the homefront (Balfour 2013, 300; Lambi [1984] 2019, 248 & 249; Retallack 2008, 52). These reasons are then interpreted using a set of frameworks from defensive realists and neoclassical realist theories, and the implications for current events such as Chinese-American relations are discussed.
Prediction of soil corrosivity index : a Bayesian belief network approach

description: Soil and their inherent properties play a very significant role in aggravating the corrosion process of metallic pipes as they are buried underground. The most common causes of corrosion are lower resistivity of soil; lower and higher pH; presence of sulfate-reducing bacteria, chlorides, sulfate and sulfides; difference in soil composition; and differential aeration of soil around the laid water pipes. The interaction of these variables are highly complex and challenging to predict the degree of corrosion due to the soil environment. In this paper, a Bayesian belief network (BBN) approach is proposed to address the inter-dependency of soil parameters and their effect on the corrosivity of soil. The proposed approach uses a combination of in situ collected data and expert knowledge of soil parameters to model the inter-dependency between soil parameters and predict the SCI using an updating capability of the BBN. The model was developed and trained using soil parameters data collected by the city of Calgary in combination with expert knowledge. The performance of the developed soil corrosivity index-Bayesian belief network (SCI-BBN) model was evaluated by the BBN model sensitivity analysis. In order to demonstrate the developed approach, the SCI-BBN model output was converted into five indexes, which are very high to very low, so that the decision makers clearly understand their system’s situation. Finally, the linguistic soil corrosivity indices of each pipes were mapped using a geographic information system (GIS) platform in order to indicate its spatial representations.

description: In this paper we revisit the so-called Bergman kernel method (BKM) for solving conformal mapping problems. This method is based on the reproducing property of the Bergman kernel function. The main drawback of this well known technique is that it involves an orthonormalization process and thus is numerically unstable. This difficulty can be, in some cases, overcome by using the Maple system, which makes no use of numeric quadrature. We illustrate this implementation by presenting a numerical example. The construction of reproducing kernel functions is not restricted to real dimension 2. Results concerning the construction of Bergman kernel functions in closed form for special domains in the framework of hypercomplex function theory suggest that BKM can also be extended to mapping problems in higher dimensions, particularly 3-dimensional cases. We describe such a generalized BKM-approach and present numerical examples obtained by the use of specially developed software packages for quaternions.

description: Object pose estimation is a key perceptual capability in robotics. We propose a fully-convolutional extension of the PoseCNN method, which densely predicts object translations and orientations. This has several advantages such as improving the spatial resolution of the orientation predictions -- useful in highly-cluttered arrangements, significant reduction in parameters by avoiding full connectivity, and fast inference. We propose and discuss several aggregation methods for dense orientation predictions that can be applied as a post-processing step, such as averaging and clustering techniques. We demonstrate that our method achieves the same accuracy as PoseCNN on the challenging YCB-Video dataset and provide a detailed ablation study of several variants of our method. Finally, we demonstrate that the model can be further improved by inserting an iterative refinement module into the middle of the network, which enforces consistency of the prediction.
