Predicting laterally loaded pile behaviour using the Pressuremeter
Creators: name: Brown, Peter Thomas
Publisher: name: University of British Columbia
Year: 2010

description: To reliably determine the lateral load-deflection behaviour of a piled foundation, a load test is commonly required. In-situ geotechnical tools, such as the cone penetrometer and the pressuremeter, have been successfully used to predict the lateral capacity of piles without the need for a load test. This research project investigates some of the variables involved in performing a pressuremeter test, and a procedure to predict the load-deflection relationship of laterally loaded piles is developed. For this thesis a total of eighty pressuremeter tests were conducted at five research sites. The variables pertaining to pressuremeter testing which were studied were: the method of installing the probe (self-boring or full-displacement), the effect of repeating a pressuremeter test at the same depth, the effect of rate of membrane inflation, the result of pore pressure dissipation in fine-grained soils, the effect of stress versus strain controlled membrane inflation, the influence of pre-pushing a small diameter pilot hole, and the effect of performing 10 slow cyclic unload-reload cycles during a test. Three laterally loaded pile case histories were documented. A total of 10 piles were laterally loaded in six separate tests. Using the pressuremeter and the program LATPILE, a prediction of the load-deflection behaviour was made for each test. In general, the deflected shape of each pile was predicted to within. 20-30% of the actual measured deflected shape.
Medium- and long-wavelength InAs/InAsSb strained-layer superlattices for
      applications in infrared nBn detectors
Creators: name: Letka, Veronica
Publisher: name: Lancaster University
Year: 2019

description: InAs/InAs1−xSbx type-II strained-layer superlattices (SLS) have potential
      applications in infrared detection, owing to their narrow tunable bandgap
      and decreased Auger recombination currents. Furthermore, the so-called nBn
      device architecture promises to suppress the majority carrier dark current
      and the surface current thanks to its inbuilt potential barrier, as well
      as the Shockley-Read-Hall (SRH) process due to the structure’s lack of a
      depletion region. This thesis reports on the growth, modelling, and
      characterisation of InAs/InAs1−xSbx nBn devices in an effort to deliver a
      viable alternative to the HgCdTe-based technology. Sample growth proceeded
      with the use of molecular beam epitaxy (MBE) on both native GaSb
      substrates and lattice-mismatched GaAs equipped with GaSb and AlSb buffer
      layers. Excellent crystallinity of devices grown on GaSb is confirmed with
      the use of X-ray diffraction (XRD) and transmission electron miscroscopy
      (TEM) scans; the GaAs-grown samples, meanwhile, display broadened XRD
      peaks and dislocations largely originating at the buffer interfaces. Group
      V intensity data reveals a Sb segregation length of ∼ 0.95 nm.
      Temperature-dependent transmission spectra of undoped SLS samples with
      varying xSb are obtained using Fourier Transform Infrared (FTIR)
      spectroscopy, and used to derive their absorption coefficients α, which
      are shown to be comparable to other technologies operating in the same
      wavelength range. Direct fundamental optical bandgaps Eg are extracted,
      and incorporated into the Kronig-Penney model of the superlattice band
      structure. Further, several nBn device parameters are characterised. Dark
      current-voltage characteristics and activation energies show
      diffusion-limited behaviour at higher temperatures, especially in the
      medium-wavelength (MWIR) detectors, but voltage-dependent current
      mechanisms dominate at lower T and in some long-wavelength (LWIR) devices.
      Responsivity R of two MWIR and two LWIR devices is obtained at target
      operational temperatures of 160 and 77 K respectively; the peak value in
      the MWIR range is found to be 1.70±0.11 A/W, corresponding to an external
      quantum efficiency of ∼ 33%. When the dark current density data is
      combined with responsivity results, the resultant specific detectivity D∗
      is found to be 5.3×1010 cmHz1/2W−1 for the MWIR samples at the operational
      bias and temperature of -0.1 V and 160 K, while one of the LWIR samples
      shows 1.1×1010 cmHz1/2W−1 at -0.2 V and 77 K.

Single-particle and collective mode couplings associated with 1- and 2-directional electronic ordering in metallic RTe$_3$ (R = Ho, Dy, Tb)

description: The coupling of phonons with collective modes and single-particle gap excitations associated with one (1d) and two-directional (2d) electronically-driven charge-density wave (CDW) ordering in metallic RTe_3 is investigated as a function of rare-earth ion chemical pressure (R=Tb, Dy, Ho) using femtosecond pump-probe spectroscopy. From the T-dependence of the CDW gap Δ_{CDW} and the amplitude mode (AM) we find that while the transition to a 1d-CDW ordered state at T_{c1} initially proceeds in an exemplary mean-field (MF) -like fashion, below T_{c1}, Δ_{CDW} is depressed and departs from the MF behavior. The effect is apparently triggered by resonant mode-mixing of the amplitude mode (AM) with a totally symmetric phonon at 1.75 THz. At low temperatures, when the state evolves into a 2d-CDW ordered state at T_{c2} in the DyTe_3 and HoTe_3, additional much weaker mode mixing is evident but no soft mode is observed.

Treatment and disposal of secondary sewage effluent through snowmaking
Creators: name: Zapf-Gilje, Reidar
Publisher: name: University of British Columbia
Year: 2010

description: When secondary sewage effluent is converted to snow, the nutrients and residual organics become concentrated in the early meltwater discharge through melt-freeze processes within the snow-pack. The early season melt comes off relatively slowly. Providing the soil can absorb the early melt, the bulk of the nutrients will be removed even if later season melt rates exceeds the soil's infil-trability. This could provide an inexpensive method for nutrient removal from secondary sewage effluents. Laboratory experiments showed that the degree of impurity concentration was largely independent of the number of diurnal melt-freeze cycles, snow depth, snow temperature and initial concentration of impurity in the snow. As a result, the removal of impurities from a snowpack can be expressed in terms of the cumulative melt discharge. A simple exponential decay process was found to describe the impurity removal well for most cases. The first 20% of the melt removed, on the average, 65% of the phosphorus and 86% of the nitrogen from snow made from sewage effluent; and 92% of the potassium chloride from snow made from potassium chloride solution. Stripping of ammonia during snow production and melting increased the overall nitrogen removal to about 90%. A field investigation of salt movement through a natural snowpack confirmed the laboratory results.

description: We use observations of the cosmological large-scale structure to derive limits on two-component hot dark matter consisting of mass-degenerate neutrinos and hadronic axions, both components having velocity dispersions corresponding to their respective decoupling temperatures. We restrict the data samples to the safely linear regime, in particular excluding the Lyman-alpha forest. Using standard Bayesian inference techniques we derive credible regions in the two-parameter space of m_a and sum(m_nu). Marginalising over sum(m_nu) provides m_a < 1.2 eV (95% C.L.). In the absence of axions the same data and methods give sum(m_nu) < 0.65 eV (95% C.L.). We also derive limits on m_a for a range of axion-pion couplings up to one order of magnitude larger or smaller than the hadronic value.

description: Accurate mass-loss rates and terminal velocities from massive stars winds are essential to obtain synthetic spectra from radiative transfer calculations and to determine the evolutionary path of massive stars. From a theoretical point of view, analytical expressions for the wind parameters and velocity profile would have many advantages over numerical calculations that solve the complex non-linear set of hydrodynamic equations. In a previous work, we obtained an analytical description for the fast wind regime. Now, we propose an approximate expression for the line-force in terms of new parameters and obtain a velocity profile closed-form solution (in terms of the Lambert $W$ function) for the $δ$-slow regime. Using this analytical velocity profile, we were able to obtain the mass-loss rates based on the m-CAK theory. Moreover, we established a relation between this new set of line-force parameters with the known stellar and m-CAK line-force parameters. To this purpose, we calculated a grid of numerical hydrodynamical models and performed a multivariate multiple regression. The numerical and our descriptions lead to good agreement between their values.

description: We investigate the physical processes occuring in the multiphase gas of a damped Lyαsystem (DLA). We base our analysis on a high quality Keck HIRES spectrum of the QSO J1211+0422 in which a DLA is detected at z=2.377. There is little contamination of the high-ion (OVI, NV, CIV, SiIV) absorption, allowing us to explore the properties of the highly ionized gas and its connection to other gas-phases. The metallicity ([Z/H]=-1.41+/-0.08), HI column density (log N(HI)=20.80+/-0.10), full-width velocity (Δ(v_ neut)=70 km/s) and relative abundances ([Si/Fe]=+0.23+/-0.05 and [N/Si]=-0.88+/-0.07) of this DLA are not unusual. However, we derive the lowest CII* cooling rate in a DLA, l_c < 10^{-27.8} erg/s per H atom (3σ). Using this stringent limit, we show that the neutral gas (confined at |v|1.5. At |v|>+39 km/s, the gas is fully and highly ionized (H+/H~1, N(CIV)>>N(CII), N(SiIV)>>N(SiII)). Based on ionization models, OVI and NV are generally difficult to produce by hard photons, while SiIV and CIV can be photoionized to a large extent. There is, however, no evidence of OVI-bearing gas at T~10^6 K associated with this DLA. In contrast, there is some evidence for narrow OVI, NV, and CIV components (unexplained by photoionization), implying too low temperatures (T < 10^5 K) for simple collisional ionization models to produce their observed column densities. Stellar feedback is a possible source for producing the high ions, but we cannot rule out accretion of non-pristine material onto the protogalaxy.

description: We study some cosmological constraints on the two phenomenological models of oscillating dark energy. In these scenarios, the equation of state of dark energy varies periodically and may provide a way to unify the early acceleration (inflation) and the late time acceleration of the universe. These models give also an effective way to tackle the so-called cosmic coincidence problem. We examine observational constraints on this class of models from the latest observational data including the \emph{gold} sample of 182 type Ia supernovae, the CMB shift parameter $R$ and the BAO measurements from the Sloan Digital Sky Survey.

description: Large firms operating in underdeveloped institutional environments of transition economies tend to invest in seemingly unrewarded corporate social responsibility (CSR) initiatives. To explain this phenomenon, we extend the literature on the motives behind CSR disclosure in agribusiness from the institutional perspective on organizational legitimacy. The thesis is that self-interest rationales for CSR disclosure, as advocated by the strategic-legitimacy perspective, fall short of explaining the full scope of instrumental motivations for the proactive and excessive transparency initiatives of agribusiness companies. Using the example of internationally listed Ukrainian agroholdings, we show that firms faced with institutions that do not appropriately support access to market transactions not only adapt to fluctuations in the business environment but also proactively address key institutional bottlenecks by engaging in higher transparency and nonmarket initiatives. The case study analysis of the voluntary CSR disclosure of four agroholdings is conducted based on in-depth interviews with corporate managers and complemented with information from corporate reports and websites. This analysis offers insights into the development of corporate farming and its economic and social repercussions in Ukraine and, more generally, expanding the concept of CSR itself.

description: A normal variety $X$ is called $H$-spherical for the action of the complex reductive group $H$ if it contains a dense orbit of some Borel subgroup of $H$. We resolve a conjecture of Hodges--Yong by showing that their spherical permutations are characterized by permutation pattern avoidance. Together with results of Gao--Hodges--Yong this implies that the sphericality of a Schubert variety $X_w$ with respect to the largest possible Levi subgroup is characterized by this same pattern avoidance condition.

description: Angular momentum in protostellar discs can be transported either radially, through turbulence induced by the magnetorotational instability (MRI), or vertically, through the torque exerted by a large-scale magnetic field. We present a model of steady-state discs where these two mechanisms operate at the same radius and derive approximate criteria for their occurrence in an ambipolar diffusion dominated disc. We obtain "weak field'' solutions - which we associate with the MRI channel modes in a stratified disc - and transform them into accretion solutions with predominantly radial angular-momentum transport by implementing a turbulent-stress prescription based on published results of numerical simulations. We also analyze "intermediate field strength'' solutions in which both radial and vertical transport operate at the same radial location. Our results suggest, however, that this overlap is unlikely to occur in real discs.

description: Incorporation of catalytically active materials into plasmonic metal nanostructures can efficiently merge the reactivity and energy harvesting abilities of both types of materials for visible light photocatalysis. Here we explore the influence of electromagnetic hotspots in the ability of plasmonic core-shell colloidal structures to induce chemical transformations. For this study, we developed a synthetic strategy for the fabrication of Au nanoparticle (NP) trimers in aqueous solution through fine controlled galvanic replacement between Ag nanoprisms and Au precursors. Core-shell Au@M NP trimers with catalytically active metals (M = Pd, Pt) were subsequently synthesized using Au NP trimers as templates. Our experimental and computational results highlight the synergy of geometry and composition in plasmonic catalysts for plasmon-driven chemical reactions.

description: On July 30th, 2019 IceCube detected a high-energy astrophysical muon neutrino candidate, IC-190730A, with a $67\%$ probability of astrophysical origin. The flat spectrum radio quasar (FSRQ) PKS 1502+106 is in the error circle of the neutrino. Motivated by this observation, we study PKS 1502+106 as a possible source of IC-190730A. PKS 1502+106 was in a quiet state in terms of UV/optical/X-ray/gamma-ray flux at the time of the neutrino alert, we therefore model the expected neutrino emission from the source during its average long-term state, and investigate whether the emission of IC-190730A as a result of the quiet long-term emission of PKS 1502+106 is plausible. We analyse UV/optical and X-ray data and collect additional observations from the literature to construct the multi-wavelength spectral energy distribution of PKS 1502+106. We perform leptohadronic modelling of the multi-wavelength emission of the source and determine the most plausible emission scenarios and the maximum expected accompanying neutrino flux. A model in which the multi-wavelength emission of PKS 1502+106 originates beyond the broad-line region and inside the dust torus is most consistent with the observations. In this scenario, PKS 1502+106 can have produced up to of order one muon neutrino with energy exceeding 100 TeV in the lifetime of IceCube. An appealing feature of this model is that the required proton luminosity is consistent with the average required proton luminosity if blazars power the observed ultra-high-energy-cosmic-ray flux and well below the source's Eddington luminosity. If such a model is ubiquitous among FSRQs, additional neutrinos can be expected from other bright sources with energy $\gtrsim 10$ PeV.

description: This paper concerns the theory of direct A(d,p)B reactions and how practical 3-body models of them are related to optical model potentials describing the interaction of the deuteron's constituents and the target A. A new definition of the nucleon optical potential is introduced which necessitates a careful examination of the boundary conditions involved in the associate coupled channels problem. The new definition turns out to be convenient for making a connection with the theory of the (d,p) reaction. The analysis is carried out within an antisymmetrised, translationally invariant formalism and provides a firm basis from a many-body point of view for the three-body force effects calculated in previous work by Dinmore, Timofeyk, Al-Khalili and Johnson.

Hence, there are still challenges in this area of BD analytics research to capture, store, process, visualise, query, and manipulate datasets to derive meaningful information that is specific to an application's domain. This chapter attempts to address this problem by studying Semantic Analytics and domain knowledge modelling, and to what extent these technologies can be utilised toward better understanding to the social textual contents. In particular, the chapter gives an overview of semantic analysis and domain ontology followed by shedding light on domain knowledge modelling, inference, semantic storage, and publicly available semantic tools and APIs. Also, the theoretical notion of Knowledge Graphs is reported and their interlinking with SBD is discussed. The utility of the semantic analytics is demonstrated and evaluated through a case study on social data in the context of politics domain.

description: Background: Many investigators have found that PKMYT1 is associated with a variety of tumors and can predict the prognosis of cancer. However, the biological status of PKMYT1, the prediction of lung adenocarcinoma, and the relationship of immune cells remain unclear. Methods: In the present article, we used the Oncomine database to research the expression of PKMYT1 in a variety of tumors. Then GEPIA2 and UALCAN databases were utilized to understand the differential expression in lung cancer. In TIMER we further explored the expression of lung adenocarcinoma versus normal tissues. Kaplan-Meier plotter and GEPIA2 were applied to calculate the effect of PKMYT1 on the prognosis of lung adenocarcinoma. The LinkedOmics database was used to understand co-expressed genes and enrichment. The TIMER databases to understand the association between PKMYT1 and immune cells. Finally, immunohistochemical validation using pathological tissues from lung adenocarcinoma patients. Results: High expression of PKMYT1 is associated with a worse prognosis in lung adenocarcinoma. At the same time, we found that PKMYT1 was associated with immune infiltration, especially B cells. In the high PKMYT1 expression group, Patients with high B-cell infiltration have a better prognosis than those with low B-cell infiltration. Showing that there is a correlation between B cells and PKMYT1 on predicting lung adenocarcinoma. Clinical samples show higher PKMYT1 expression in lung adenocarcinoma compared to normal tissue and correlate with poor prognosis. Conclusion: PKMYT1 can predict the prognosis of LUAD and has a correlation with immune cells, especially B cells, and in high PKMYT1 expression group, Patients with a higher B cells infiltration had a better prognosis than patients with low B cell infiltration. B cells infiltration may be responsible for the ability of PKMYT1 to predict the prognosis of lung adenocarcinoma. Our study has important implications for future deeper exploration of PKMYT1 for immunotherapy in LUAD.

description: The three-dimensional Klein-Gordon oscillator is shown to exhibit an algebraic structure known from supersymmetric quantum mechanics. The supersymmetry is found to be unbroken with a vanishing Witten index, and it is utilized to derive the spectral properties of the Klein-Gordon oscillator, which is closely related to that of the non-relativistic harmonic oscillator in three dimensions. Supersymmetry also enables us to derive a closed-form expression for the energy-dependent Green's function.

Flood advisor : an expert system for flood estimation
Creators: name: Fayegh, A. David
Publisher: name: University of British Columbia

description: Expert computer programs have recently emerged from research on artificial intelligence as a practical problem-solving tool. An expert system is a knowledge-based program that imitates the problem-solving behaviour of a human expert to solve complex real-world problems. While conventional programs organize knowledge on two levels: data and program, most expert programs organize knowledge on three levels: data, knowledge base, and control. Thus, what distinguishes such a system from conventional programs is that in most expert systems the problem solving model is treated as a separate entity rather than appearing only implicitly as part of the coding of the program. The purpose of this thesis is twofold. First, it is intended to demonstrate how domain-specific problem-solving knowledge may be represented in computer memory by using the frame representation technique. Secondly, it is intended to simulate a typical flood estimation situation, from the point-of-view of an expert engineer. A frame network was developed to represent, in data structures, the declarative, procedural, and heuristic knowledge necessary for solving a typical flow estimation problem. The control strategy of this computer-based consultant (FLOOD ADVISOR) relies on the concept that reasoning is dominated by a recognition process which is used to compare new instances of a given phenomena to the stereotyped conceptual framework used in understanding that phenomena. The primary purpose of the FLOOD ADVISOR is to provide interactive advice about the flow estimation technique most suitable to one of five generalized real-world situations. These generalizations are based primarily on the type and quantity of the data and resources available to the engineer. They are used to demonstrate how problem solving knowledge may be used to interactively assist the engineer in making difficult decisions. The expertise represented in this prototype system is far from complete and the recommended solution procedures for each generalized case are in their infancy. However, modifications may be easily implemented as the domain-specific expert knowledge becomes available. It is concluded that over the long term, this type of approach for building problem-solving models of the real world are computationally cheaper and easier to develop and maintain than conventional computer programs.

description: Recently, a topological field theory of membrane-matter coupled to BF theory in arbitrary spacetime dimensions was proposed [1]. In this paper, we discuss various aspects of the four-dimensional theory. Firstly, we study classical solutions leading to an interpretation of the theory in terms of strings propagating on a flat spacetime. We also show that the general classical solutions of the theory are in one-to-one correspondence with solutions of Einstein's equations in the presence of distributional matter (cosmic strings). Secondly, we quantize the theory and present, in particular, a prescription to regularize the physical inner product of the canonical theory. We show how the resulting transition amplitudes are dual to evaluations of Feynman diagrams coupled to three-dimensional quantum gravity. Finally, we remove the regulator by proving the topological invariance of the transition amplitudes.

description: The inelastic neutral reaction of neutrino on 4He is calculated using two modern nucleon--nucleon potentials. Full final state interaction among the four nucleons is considered, via the Lorentz integral transform (LIT) method. The effective interaction hyperspherical-harmonic (EIHH) approach is used to solve the resulting Schrodinger like equations. A detailed energy dependent calculation is given in the impulse approximation.

description: We propose a multiscale spatio-temporal graph neural network (MST-GNN) to predict the future 3D skeleton-based human poses in an action-category-agnostic manner. The core of MST-GNN is a multiscale spatio-temporal graph that explicitly models the relations in motions at various spatial and temporal scales. Different from many previous hierarchical structures, our multiscale spatio-temporal graph is built in a data-adaptive fashion, which captures nonphysical, yet motion-based relations. The key module of MST-GNN is a multiscale spatio-temporal graph computational unit (MST-GCU) based on the trainable graph structure. MST-GCU embeds underlying features at individual scales and then fuses features across scales to obtain a comprehensive representation. The overall architecture of MST-GNN follows an encoder-decoder framework, where the encoder consists of a sequence of MST-GCUs to learn the spatial and temporal features of motions, and the decoder uses a graph-based attention gate recurrent unit (GA-GRU) to generate future poses. Extensive experiments are conducted to show that the proposed MST-GNN outperforms state-of-the-art methods in both short and long-term motion prediction on the datasets of Human 3.6M, CMU Mocap and 3DPW, where MST-GNN outperforms previous works by 5.33% and 3.67% of mean angle errors in average for short-term and long-term prediction on Human 3.6M, and by 11.84% and 4.71% of mean angle errors for short-term and long-term prediction on CMU Mocap, and by 1.13% of mean angle errors on 3DPW in average, respectively. We further investigate the learned multiscale graphs for interpretability.

description: We present HST/ACS observations of 19 nearby M subdwarfs in a search for binary systems. Other than the wide common proper motion pair LHS 2140/2139, none of our sdM and esdM targets are found to be binaries. Our survey is sensitive to equal-luminosity companions at close (2-8 AU) separations, while sub-stellar secondaries could have been detected at separations in the range of 6-30 AU. To check for wide binaries, we have compared the POSS I and II images in a field of view as large as 10'x10', but could not detect a single co-moving star for any of the targets. Combining our results with those from Gizis & Reid, we have a binary fraction of 3% (1/28). Detection of a small number of M subdwarf binaries reported in the literature suggests a higher fraction than the one obtained here, probably comparable to that found for the more massive solar-type stars in the halo (13-15%). Comparison with the disk M dwarf fraction (25%) however suggests multiplicity to be rare among the lowest mass halo stars, implying the two populations formed under different initial conditions. The low binary fraction in our survey could be explained by selection biases. A decrease in multiplicity has been observed in the disk for masses below 0.1Msun, the peak in the disk mass function (MF). The globular cluster MF is found to peak at about 0.33Msun, with a decrease in the number of stars per unit mass below the peak mass. Our sample being composed of stars with masses between ~0.2 and 0.085 Msun suggests that a decrease in multiplicity similar to the disk may also be true for the halo stars, but perhaps below a mass of ~0.3Msun. A higher M subdwarf binary fraction may be obtained if the selected primaries have masses near or higher than the peak in the MF.

description: Interoperation for data sharing between permissioned blockchain networks relies on networks' abilities to independently authenticate requests and validate proofs accompanying the data; these typically contain digital signatures. This requires counterparty networks to know the identities and certification chains of each other's members, establishing a common trust basis rooted in identity. But permissioned networks are ad hoc consortia of existing organizations, whose network affiliations may not be well-known or well-established even though their individual identities are. In this paper, we describe an architecture and set of protocols for distributed identity management across permissioned blockchain networks to establish a trust basis for data sharing. Networks wishing to interoperate can associate with one or more distributed identity registries that maintain credentials on shared ledgers managed by groups of reputed identity providers. A network's participants possess self-sovereign decentralized identities (DIDs) on these registries and can obtain privacy-preserving verifiable membership credentials. During interoperation, networks can securely and dynamically discover each others' latest membership lists and members' credentials. We implement a solution based on Hyperledger Indy and Aries, and demonstrate its viability and usefulness by linking a trade finance network with a trade logistics network, both built on Hyperledger Fabric. We also analyze the extensibility, security, and trustworthiness of our system.

description: In this paper we present a scheme for ground state cooling of a flexural mode of a nanomechanical beam incorporated in a loop-shaped Cooper-pair box (CPB) circuit. Via the Lorentz force coupling of the beam motion to circulating CPB-circuit currents, energy is transferred to the CPB qubit which acts as a dissipative two-level system. The cooling process is driven by a detuned gate-voltage drive acting on the CPB. We analyze the cooling force spectrum and present analytical expressions for the cooling rate and final occupation number for a wide parameter regime. In particular, we find that cooling is optimized in a strong drive regime, and we present the necessary conditions for ground-state cooling.

description: This study utilizes regression analysis and one-sample t-tests to investigate how AI-driven customization affects e-commerce consumer happiness. Online shopping has been revolutionized by AI-powered services like chatbots, predictive discounts, and tailored product suggestions. The results demonstrate that AI-driven personalization considerably raises consumer happiness, confirming the idea that greater degrees of AI customization result in happier customers. Further supporting the notable positive correlation between AI personalization and customer happiness is regression analysis, which shows how important AI-driven variables are in influencing customer experiences. The report emphasizes how crucial it is to improve AI-powered customer service, guarantee data privacy transparency, optimize AI algorithms for better suggestions, and use predictive discounting techniques. In order to improve customization strategies, future studies should examine demographic differences in AI adoption. E-commerce companies may increase consumer interaction, establish credibility with AI-driven customisation, and cultivate enduring client loyalty by putting these tactics into practice.
