description: Wie funktioniert Lernen? Wie kann ich als Lehrperson bei meinen Schülerinnen und Schülern verstehensorientierte und kompetenzfördernde Lernprozesse anregen? Die Auseinandersetzung mit diesen Grundfragen des Lehrens und Lernens steht im Zentrum des Studienbands "Grundlagen und Grundformen des Unterrichtens". Der Studienband setzt sich mit den zentralen Aspekten auseinander, die einer Lehrperson bei der Anregung und Begleitung von Lernprozessen ihrer Schülerinnen und Schüler in Bezug auf deren Lernerfolg zukommt. Dabei wird aufgezeigt, wie wichtig das Wissen zu gutem Unterricht und zu Lernprozessen für die Gestaltung lernwirksamen Unterrichts ist. Im Studienband wird u.a. auf folgende Fragen eingegangen: Welche Bedeutung hat die Lehrperson? Was ist guter Unterricht? Welches sind die zentralen Aufgaben der Lehrperson? Was ist Lernen? Wie verläuft ein Lernprozess? Wie rege ich als Lehrperson Lernen an? Wie spielen die Lehraktivitäten der Lehrperson mit den Lernaktivitäten der Schülerinnen und Schüler zusammen? Was müssen Lehrpersonen wissen und können? Der an der PH Luzern für den Einsatz im stufenübergreifenden Grundjahr-Mentorat (eine Mischform von Theorievermittlung und berufspraktischer Einführung) entwickelte Studienband wird interessierten Kreisen als OER (Open Educational Resources) zur Verfügung gestellt.

description: Let M and N be compact Riemannian manifolds with sectional curvature K ⩽ 0 such that M has dimension ⩾ 3 and rank ⩾ 2. If there exists a C0 conjugacy F between the geodesic flows of the unit tangent bundles of M and N, then there exists an isometry G: M → N that induces the same isomorphism as F between the fundamental groups of M and N.

description: The ongoing race to improve computer graphics leads to more complex GPU hardware and ray tracing techniques whose internal functionality is sometimes hidden to the user. Bounding volume hierarchies and their construction are an important performance aspect of such ray tracing implementations. We propose a novel approach that utilizes binary instrumentation to collect memory traces and then uses them to extract the bounding volume hierarchy (BVH) by analyzing access patters. Our reconstruction allows combining memory traces captured from multiple ray tracing views independently, increasing the reconstruction result. It reaches accuracies of 30% to 45% when comparing against the ground-truth BVH used for ray tracing a single view on a simple scene with one object. With multiple views it is even possible to reconstruct the whole BVH, while we already achieve 98% with just seven views. Because our approach is largely independent of the data structures used internally, these accurate reconstructions serve as a first step into estimation of unknown construction techniques of ray tracing implementations.

description: A magnetically retrievable catalytic system involving Ag(I) dithiocarbamate supported on functionalized cellulose was prepared. The structure of this hybrid nano-composite was characterized by various techniques. In addition, to describe the metal-ligand interactions present in the nano-composite, covalent and electrostatic interactions, density functional theory model and quantum theory of atoms in molecule method were employed. The resultant nano-composite exhibits remarkable catalytic efficacy in the synthesis of 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-phenylnicotinonitriles from the reaction of 3-acetylcoumarin, aromatic aldehydes, and malononitrile. Its recoverability and reusability for this catalyst was examined in several runs, which showed no appreciable loss after five runs. The facile accessibility to the starting materials, and conducting the reactions in the eco-friendly and cost-effective conditions are the other merits of such new catalyst. Ambient reaction conditions, wide substrate scope, and facile accessibility to the starting materials, are some of the other outstanding features of this protocol that make it economic and sustainable.

On the freeness of equisingular deformations of plane curve singularities
Creators: name: Damon, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: We consider surface singularities in arising as the total space of an equisingular deformation of an isolated curve singularity of the form f(x,y)+zg(x,y) with f and g weighted homogeneous. We give a criterion that such a surface is a free divisor in the sense of Saito. We deduce that the Hessian deformation defines a free divisor for nonsimple weighted homogeneous singularities, and that the failure of this property “almost” characterizes the simple singularities. The criterion also yields distinct deformations of the same curve singularity, exactly one of which is free, showing that freeness is not a topological property.

description: We present the capabilities of Galapagos--2 and Galfitm in the context of fitting 2-component profiles to galaxies, on the way to providing complete multi-band, multi-component fitting of large samples of galaxies in future surveys. We release both the code and the fit results to 234,239 objects from the DR3 of the Gama survey, a sample significantly deeper than previous works. We use stringent tests on both simulated and real data, as well as comparison to public catalogues to evaluate the advantages of using multi-band over single-band data. We show that multi-band fitting using Galfitm provides significant advantages when trying to decompose galaxies into their individual constituents, as more data are being used, by effectively being able to use the colour information buried in the individual exposures to its advantage. Using simulated data, we find that multi-band fitting significantly reduces the deviations from real parameter values, allows component sizes and Sérsic indices to be recovered more accurately, and, by design, constrains the band-to-band variations of these parameters to more physical values. On both simulated and real data, we confirm that the SEDs of the 2 main components can be recovered to fainter magnitudes compared to using single-band fitting, which tends to recover disks and bulges to - on average - have identical SEDs when the galaxies become too faint, instead of the different SEDs they truly have. By comparing our results to those provided by other fitting codes, we confirm that they agree in general, but measurement errors can be significantly reduced by using the multi-band tools developed by the MegaMorph project. We conclude that the multi-band fitting employed by Galapagos-2 and Galfitm significantly improves the accuracy of structural galaxy parameters and enables much larger samples to be be used in a scientific analysis.

An Apparent Redshift Dependence of Quasar Continuum: Implication for Cosmic Dust Extinction?

description: We investigate the luminosity and redshift dependence of the quasar continuum by means of composite spectrum using a large non-BAL radio-quiet quasar sample drawn from the Sloan Digital Sky Survey. Quasar continuum slopes in the UV-Opt band are measured at two different wavelength ranges, i.e., $α_{\nu12}$ ($1000\sim 2000 \rmÅ$) and $α_{\nu24}$ ($2000 \sim 4000 \rmÅ$) derived from power law fitting. Generally, the UV spectra slope becomes harder (higher $α_ν$) towards higher bolometric luminosity. On the other hand, when quasars are further grouped into luminosity bins, we find both $α_{\nu12}$ and $α_{\nu24}$ show significant anti-correlation with redshift (i.e., quasar continuum becomes redder towards higher redshift). We suggest that the cosmic dust extinction is very likely the cause of this observed $α_ν-z$ relation. We build a simple cosmic dust extinction model to quantify the observed reddening tendency and find an effective dust density $nσ_v \sim 10^{-5}h~\rm Mpc^{-1}$ at $z<1.5$. The other possibilities that could produce such a reddening effect have also been discussed.

A rationality conjecture about Kontsevich integral of knots and its implications to the structure of the colored Jones polynomial
Creators: name: Rozansky, L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: We formulate a conjecture about the structure of the Kontsevich integral of a knot. We describe its value in terms of the generating functions for the numbers of external edges attached to closed 3-valent diagrams. We conjecture that these functions are rational functions of the exponentials of their arguments, their denominators being the powers of the Alexander–Conway polynomial. This conjecture implies the existence of an expansion of a colored Jones (HOMFLY) polynomial in powers of q − 1 whose coefficients are rational functions of qα (α being the color assigned to the knot). We show how to derive the first Kontsevich integral polynomial associated to the θ-graph from the rational expansion of the colored SU(3) Jones polynomial.

description: Previously derived Faraday rotation constraints on the volume-filling intergalactic magnetic field (IGMF) have used analytic models that made a range of simplifying assumptions about magnetic field evolution in the intergalactic medium and did not consider the effect of baryonic feedback on large-scale structures. In this work we revise existing Faraday rotation constraints on the IGMF using a numerical model of the intergalactic medium from the IllustrisTNG cosmological simulation that includes a sophisticated model of the baryonic feedback. We use the IllustrisTNG model to calculate the rotation measure and compare the resulting mean and median of the absolute value of the rotation measure with data from the NRAO VLA Sky Survey (NVSS). The numerical model of the intergalactic medium includes a full magneto-hydrodynamic model of the compressed primordial magnetic field as well as a model of the regions where the magnetic field is not primordial, but is rather produced by the process of baryonic feedback. Separating these two types of regions, we are able to assess the influence of the primordial magnetic field on the Faraday rotation signal. We find that by correcting for regions of compressed primordial field and accounting for the fact that part of the intergalactic medium is occupied by magnetic fields spread by baryonic feedback processes rather than by the primordial field relaxes the Faraday rotation bound by a factor of $\simeq 3$. This results in $B_0<1.8\times10^{-9}$ G for large correlation length IGMFs.

Fermi arcs, pseudogap and collective excitations in doped Sr2IrO4: A generalized fluctuation exchange study

description: Motivated by recent experimental measurements, we study the quasiparticle spectra and the collective excitations in doped Sr$_2$IrO$_4$, in which the interesting interplay between the electronic correlations and strong spin-orbital coupling (SOC) exists. To include the SOC, we use the Hugenholtz diagrams to extend the fluctuation exchange (FLEX) approach to the case where the SU(2) symmetry can be broken. By using this generalized FLEX method, we find a weak pseudogap behavior near $(π,0)$ in the slightly electron-doped system, with the corresponding Fermi arc formed by the partial destruction of Fermi surface. Similar features also appear in the hole-doped system, however, the position of the Fermi arc is rotated $45^\circ$ with respect to the former. These results are consistent with the recent angle-resolved photoemission spectra in Sr$_2$IrO$_4$. We demonstrate that these anomalous features are mainly caused by the isospin fluctuations derived from the effective $J_{\text{eff}}=1/2$ doublet.

Machine learning techniques to predict housing prices and identify factors affecting them
Creators: Patel, Aditya Kalpeshbhai

Publisher: name: University of Alberta Library
Year: 2023

House prices have a big impact on the economy, and customers and real estate agents are quite concerned about the price changes. Every year, housing prices rise, which ultimately highlights the necessity for a method or plan that might forecast home prices in the future. According to research, house owners and the real estate industry frequently worry about price swings in real estate. To identify pertinent features and the most effective models to anticipate home values, a review of the literature is conducted before the creation and analysis of machine learning models. Physical attributes including the living area, plot area, location, number of bedrooms etc. affect the price of a property directly. Previous studies have been based on just a few of these variables. This paper used dataset for USA housing with different internal characteristics and applied CART with ensemble techniques (Boosting and Bagging), K-Nearest Neighbor, Local Regression and Random Forest to predict property prices of houses and their relationship with different features. The paper will validate the different machine learning techniques applied by using k-fold cross validation and RMSE to provide an optimistic view on property price prediction.

Synthetic image data generation using GAN with statistical similiarity
Creators: Nirmal, Bhavin Naginbhai
Publisher: name: University of Alberta Library
Year: 2023

Synthetic image generation using Generative Adversarial Networks (GANs) has emerged as a promising technique to address the challenge of limited datasets in the field of garbage classification. With supervised machine learning algorithms relying on labeled data and larger training examples, the small size and scarcity of annotated samples in the medical imaging domain pose significant obstacles. Traditional data augmentation techniques offer limited diversity, motivating the exploration of synthetic data examples to introduce more variability and enhance the training process. GANs, known for their ability to generate high-quality and realistic images, have gained popularity in computer vision tasks and have been successfully applied to medical imaging applications. In this study, we investigate the application of GANs for synthetic image generation in the garbage classification dataset. By training the GAN model with a large number of images, we aim to generate synthetic images that closely resemble real images, thereby expanding the dataset and improving the robustness of garbage classification algorithms. We also evaluate the similarity between

the real and generated images using metrics such as the Inception Score and Frechet Inception Distance. Through our research, we seek to demonstrate the efficacy of GAN-based synthetic image generation as a means to enhance the garbage classification dataset and improve the accuracy of classification algorithms for efficient waste management.
Facial emotion recognition

Year: 2023

Facial emotion recognition has gained substantial attention in past decade’s as a key factor for human-computer interaction. Emotion recognition refers to the ability to identify and understand human emotions based on various cues, such as facial expressions, voice tone, body language, and physiological signals. This report presents a comprehensive study of facial emotion recognition using the FER2013+ dataset, providing an overview of its structure, size and different emotion categories. There are several deep learning architectures for facial emotion recognition, the method that is used for this project is Convolutional Neural Network (CNN). The model is implemented and trained on the FER2013+ dataset, and their performance are evaluated using various metrics like precision, recall, f1-score. The report also explores real-worlds applications of facial emotion recognition including emotion-aware user interfaces, investigation purposes, personalized recommendation systems, and mental health monitoring tools.
Do Loyal Users Enjoy Better Recommendations? Understanding Recommender Accuracy from a Time Perspective

description: In academic research, recommender systems are often evaluated on benchmark datasets, without much consideration about the global timeline. Hence, we are unable to answer questions like: Do loyal users enjoy better recommendations than non-loyal users? Loyalty can be defined by the time period a user has been active in a recommender system, or by the number of historical interactions a user has. In this paper, we offer a comprehensive analysis of recommendation results along global timeline. We conduct experiments with five widely used models, i.e., BPR, NeuMF, LightGCN, SASRec and TiSASRec, on four benchmark datasets, i.e., MovieLens-25M, Yelp, Amazon-music, and Amazon-electronic. Our experiment results give an answer "No" to the above question. Users with many historical interactions suffer from relatively poorer recommendations. Users who stay with the system for a shorter time period enjoy better recommendations. Both findings are counter-intuitive. Interestingly, users who have recently interacted with the system, with respect to the time point of the test instance, enjoy better recommendations. The finding on recency applies to all users, regardless of users' loyalty. Our study offers a different perspective to understand recommender accuracy, and our findings could trigger a revisit of recommender model design.

A corporate Christianity: Religion in the early modern Hudson's Bay COmpany
Creators: Bradford, Tolly
Publisher: name: University of Alberta Library
Year: 2023

The early modern Hudson’s Bay Company (HBC) built a form of Christianity that was decidedly corporate in its design. Unlike the way Catholicism in the French fur trade was deployed to achieve imperial as well as commercial ends, Christianity in the HBC was positioned exclusively with commerce in mind. This meant it was used not to colonize Indigenous cultures or spaces but to control and protect the company’s overseas resources and support corporate relations in London. Even when this use changed in the early 1800s as baptism and religious education was

offered to mixed-ancestry children of company men, the corporate agenda remained at the heart of the company’s use of religion. The history of religion in the early modern HBC underlines that the company’s identity and aspirations at this time were commercial rather than imperial.

description: The theory of spin fluctuations is developed for an ensemble of localized electrons taking into account both hyperfine interaction of electron and nuclear spins and electron hopping between the sites. The analytical expression for the spin noise spectrum is derived for arbitrary relation between the electron spin precession frequency in the field of the nuclear fluctuation and the hopping rate. An increase in the hopping rate results in the drastic change of the spin noise spectrum. The effect of an external magnetic field is briefly addressed.

description: The correlators of Wilson-line operators in non-abelian gauge theories are known to exponentiate, and their logarithms can be organised in terms of the collections of Feynman diagrams called Cwebs. The colour factors that appear in the logarithm correspond to completely connected diagrams and are determined by the web mixing matrices. In this article we introduce several new concepts: (a) Normal ordering of the diagrams of a Cweb, (b) Fused-Webs (c) Basis and Family of Cwebs. We use these ideas together with a Uniqueness theorem that we prove to arrive at an understanding of the diagonal blocks, and several null matrices that appear in the mixing matrices. We demonstrate using our formalism that, once the basis Cwebs present upto order $α_{s}^{n}$ are determined, the number of exponentiated colour factors for several classes of Cwebs starting at order $α_{s}^{n+1}$ can be predicted. We further provide complete results for the mixing matrices, to all orders in perturbation theory, for two special classes of Cwebs using our framework.

description: We consider C1C1 nonsingular flows on a closed 3-manifold under which there is no transverse disk that flows continuously back into its own interior. We provide an algorithm for modifying any branched surface transverse to such a flow ϕ that terminates in a branched surface carrying a foliation F precisely when F is transverse to ϕ. As a corollary, we find branched surfaces that do not carry foliations but that lift to ones that do.
The making of a company colony: The fur trade war, the colonial office, and the metamorphosis of the Hudson's Bay Company
Creators: Bradford, Tolly
Connors, Rich
Publisher: name: University of Alberta Library
Year: 2020

This article argues that between 1810 and 1816 the Hudson’s Bay Company (HBC) underwent a managerial metamorphosis: where it had previously and then only timidly claimed economic privileges and authority in North America, after this period the company’s directors in London began staking claim to authority over legal, political, and even humanitarian affairs in the area covered by its charter, Rupert’s Land. Building on arguments that have been used to theorize the East India Company, this article concludes that in making these claims the hbc became what might be called a company colony, seeking to act as both a private business and a colonial government endowed with the power of the British state. In presenting this new interpretation of the hbc’s early nineteenth-century experiences, we challenge the persistent historiographical depiction of the HBC as a business-first organization operating outside the traditional patterns of the so-called Second British Empire, thereby offering a new way of understanding both the HBC and other British chartered trading companies during the nineteenth century.

Comparative analysis of data synthesis algorithms for liver cirrhosis classification
Creators: Radhadpuri, Shahenoor Aslambhai
Publisher: name: University of Alberta Library
Year: 2023

Liver cirrhosis is a serious global health issue, causing a significant number of fatalities each year. Liver biopsy, the gold standard for diagnosis and staging, is an invasive procedure with potential complications and sampling errors. Noninvasive methods are being explored, but they are in early stages or require more resources. Artificial Intelligence (AI) has shown promise in healthcare, contingent on well-curated medical data. However, real-world medical data is often limited, leading to the use of synthetic data for training AI algorithms. Synthetic data generation (SDG) offers a privacy-preserving approach, preserving information while not containing original data. This study evaluates various SDG algorithms, including statistical methods and variations of Generative Adversarial Network (GAN), on Liver Function Tests (LFT) datasets. The aim is to augment the available dataset, providing diverse samples for training Machine Learning (ML) models through synthetic data based on actual samples. This approach improves the model’s understanding of underlying patterns and characteristics, resulting in more accurate liver cirrhosis diagnosis. The study emphasizes the importance of using laboratory test results for liver cirrhosis diagnosis as they offer a cost-effective alternative to invasive procedures. In this work, three tabular data generation algorithms are used namely CTGAN, Gaussian Copula, and CopulaGAN. Based on certain quantitative and qualitative methods, I present an analysis and evaluation of the most prominent algorithm for tabular data generation for Liver Cirrhosis Classification. Leveraging synthetic data to refine AI models, this research aims to contribute to advancements in liver disease diagnosis and treatment.

The initiative to standardize post-quantum cryptography by the National Institute of Standards (NIST) has been actively regulating post-quantum cryptographic algorithms. CRYSTALS-Kyber, a lattice-based key encapsulation mechanism that is being investigated as a standardizing candidate, is examined. NIST recently selected CRYSTALS-Kyber as a new public-key encryption and key-establishment algorithm for standardization, which marks its importance of assessing how well its implementations would withstand side-channel attacks. In this paper, a profiling side-channel attack against a hardware execution of CRYSTALS-Kyber of security parameter k = 2, Kyber512 is shown. First, power-based side-channel flaws in the Fujisaki-Okamoto transform are discovered, allowing non-ECC methods to leak information about decrypted messages. These vulnerabilities were exploited and the traces were implemented in that algorithm for demonstrating practical attacks. The aim is to experimentally validate attacks on implementations sourced from the pqm4 library, which are executed on the Atmega328 microcontroller. These attacks result in complete key-recovery in the form of coefficients on all the targeted scheme. Additionally, the attacks can retrieve long-term secret keys in a few hundred chosen-ciphertext queries, indicating the feasibility of the approach. The attack relies on building flawed ciphertexts that ensure that a specific intermediary variable becomes closely linked to the secret key when decapsulated by the target device. An attacker who uses side channels to gain information about the secret dependent variable can then recover the entire secret key. Based on the project, the success rate of performed side-channel attack is around 98% and after further experimentation, the success rate would be reduced.

description: We calculate Higgs decay rates into γγ and Zγ in the Minimal Supersymmetric Standard Model (MSSM) and (B-L) Supersymmetric Standard Model (BLSSM) by allowing for contributions from light staus and charginos. We show that sizable departures are possible from the SM predictions for the 125 GeV state and that they are testable during run 2 at the Large Hadron Collider. Furthermore, we illustrate how a second light scalar Higgs signal in either or both these decay modes can be accessed at the CERN machine rather promptly within the BLSSM, a possibility instead precluded to the MSSM owing to the much larger mass of its heavy scalar state.

description: Objective: The purpose of this study was to assess the psychometric properties of the Patient Perception of Migraine Questionnaire (PPMQ), which measures patient satisfaction with migraine therapy. Methods and Data: The PPMQ was administered to 940 patients as part of a 3-month, multinational, open-label, clinical trial comparing the effects of oral naratriptan 2.5 mg with the patient's customary therapy for the treatment of migraine. Psychometric properties of the PPMQ were evaluated in terms of its latent factor structure, validity, reliability, sensitivity, and development of a scoring method. Classical Test theory and Item Response theory (IRT) modeling were both used to measure reliability. Results: The PPMQ was able to detect treatment differences (P > .001), and all items significantly correlated with diary ratings of headache pain (r = .18−.51, p > .0001) and the Medical Outcomes Short Form-36 pain scale (r = .27, p > .0001). A principal components factor analysis revealed that the items on the PPMQ were psychometrically distinct and unidimensional (loadings, 0.74–0.91), with the exclusion of two items. The reliability (i.e., internal item consistency) of the PPMQ post-trial was high in both treatment groups (Cronbach's α = 0.96). An IRT analysis also ensured the formation of homogenous items, which were stable on repeat administration. Items did not require weighting and can be simply summed to yield a total score. Conclusion: Based on the data from this one clinical trial, the 15-item PPMQ was shown to be a valid and reliable instrument that seems to efficiently and comprehensively measure patient perception of drug attributes in relation to the treatment of symptoms associated with migraine headaches.

Updated article originally published in Studia Salvatoriana Polonica (Kontext literacki a przysłowia biblijne = Literal Context and Biblical Proverbs), in the first part deals with the methodological matters concerning various contexts in the interpretation of biblical proverbs with the emphasis that the only available and objective context remain the literal one. The second part offers two examples of groupings of proverbs that constitute literal units (Prov 12:3–7 and 12:8–14). The method uses is Biblical and Semitic Rhetorical analysis.
title: Virginity and Sexual Initiation in Mexico: The Dialogic Negotiation of Meaning
Creators: name: Amuchastegui Herrera, Ana Maria Guadalupe
Publisher: name: Goldsmiths, University of London

description: This research analyzes the construction of meaning of virginity and first sexual intercourse among young men and women in Mexican present society and culture. It documents a process of social change in which discourses of sexuality that had been dominant and unchallenged in Mexico, are now coexisting with modern constructions of subjectivity and sexuality. Sexual meanings are considered to be constructed by at least four different elements: social and local discourses, dialogues and the experience of the body. From a phenomenological approach based on Bakhtin's and Voloshinov's work, this thesis discusses how individuals' experience of sexuality is linked to these four elements, by looking at the metaphors, stories, voices and rhetoric devices individuals use in their accounts. This is done through the interpretation of 23 conversations carried out with men and women from three different communities: an indigenous town in the south of the country, a rural settlement in central Mexico and an urban neighborhood in Mexico City. The research situation is considered itself a dialogue, in which both researcher's and participants' discourses are interpreted. Both speakers are conceived as culturally situated and visible, and their interaction is looked at in terms of the negotiation of meaning within a power relationship. Two main categories that were inductively constructed are discussed in light of excerpts of field conversations: a) The construction of gendered subjects of sexuality and the role of sexual knowledge, and b) the moral dimension of sexuality: evil, the sacred and rituals of sexual initiation. The thesis also discusses the relevance of Foucault's work and Western theories on sexuality and gender identity, for the hybrid reality of Latin American present culture.
Rapid Spin Up and Spin Down of Flow Along Slopes

description: The near-bottom mixing that allows abyssal waters to upwell tilts isopycnals and spins up flow over the flanks of mid-ocean ridges. Meso- and large-scale currents along sloping topography are subjected to a delicate balance of Ekman arrest and spin down. These two seemingly disparate oceanographic phenomena share a common theory, which is based on a one-dimensional model of rotating, stratified flow over a sloping, insulated boundary. This commonly used model, however, lacks rapid adjustment of interior flows, limiting its ability to capture the full physics of spin up and spin down of along-slope flow. Motivated by two-dimensional dynamics, the present work extends the one-dimensional model by constraining the vertically integrated cross-slope transport and allowing for a barotropic cross-slope pressure gradient. This produces a closed secondary circulation by forcing Ekman transport in the bottom boundary layer to return in the interior. The extended model can thus capture Ekman spin up and spin down physics: the interior return flow is turned by the Coriolis acceleration, leading to rapid \linelabel{ll:slowdiff}rather than slow diffusive adjustment of the along-slope flow. This transport-constrained one-dimensional model accurately describes two-dimensional mixing-generated spin up over an idealized ridge and provides a unified framework for understanding the relative importance of Ekman arrest and spin down of flow along a slope.

Chat-bots could be considered as one of widely used technologies since it increases the business efficiency and throughput. Proposed project is to develop a web based chat-bot that is capable of booking appointments via the website Telecare Plus. Machine learning techniques are used to provide an interactive and personalized learning experience for users. Users details are be retrieved by the bot to book an appointment, if the user gives permission. Various tools and resources such as python libraries are integrated with the chat-bot to help users to practice and provide answers. It is not easy for many users to book an online appointment because of the technical knowledge and skill levels they have. One of the main advantages of this chat-bot is the users are able to provide details to book an appointment in a similar way they do when a patient interacts with a live agent. User studies are used to evaluate the effectiveness of the chat-bot as well as to assess its usability, engagement, and outcomes. The medical field could have a significant impact because of this project by providing an accessible and efficient way to book appointments.

description: This study investigated the role of Information Communication Management (ICM) as a predictor of effective administration in secondary schools in Enugu State. Guided by two research questions and two null hypotheses, the study employed a correlational research design. The population consisted of 8,588 principals and teachers in government-owned secondary schools, with a sample of 12 principals and 356 teachers, selected using simple random sampling from three educational zones. Two instruments, the Information Communication Management Questionnaire (ICMQ) and the Effective Administration Questionnaire (EAQ), were developed and validated by experts in educational management and measurement from Godfrey Okoye University, Enugu. Test-retest reliability yielded coefficients of 0.83 and 0.86. Data were analysed using mean, standard deviation, correlation coefficients, and simple regression at a 0.05 significance level. The findings revealed that ICM significantly predicted effective administration in secondary schools, showing a strong positive correlation. Based on the results, it was recommended that principals enhance their communication strategies to improve school administration.
