description: In recent years, the data mining techniques have met a serious challenge due to the increased concerning and worries of the privacy, that is, protecting the privacy of the critical and sensitive data. Different techniques and algorithms have been already presented for Privacy Preserving data mining, which could be classified in three common approaches: Data modification approach, Data sanitization approach and Secure Multi-party Computation approach. This paper presents a Data modification- based Framework for classification and evaluation of the privacy preserving data mining techniques. Based on our framework the techniques are divided into two major groups, namely perturbation approach and anonymization approach. Also in proposed framework, eight functional criteria will be used to analyze and analogically assessment of the techniques in these two major groups. The proposed framework provides a good basis for more accurate comparison of the given techniques to privacy preserving data mining. In addition, this framework allows recognizing the overlapping amount for different approaches and identifying modern approaches in this field.

description: We investigate the proposed experimental setup for measuring the topological charge in a an Ising anyon system by means of Fabry-Pérot interferometry with a chiral edge state. We show that such an interferometer has the unintended but not necessarily unwelcome effect of stabilizing the state of the system being measured (i.e., a topological qubit). We show further that interactions between the edge mode and the localized bulk quasiparticles can have the effect of polarizing the qubit, stabilizing its state. We discuss the these results in the context of recent interferometer experiments in the 5/2 fractional quantum Hall state, where the first of these effects is small, but the second may be relevant to the observed phenomena.

description: We, first, analytically work out the long-term, i.e. averaged over one orbital revolution, perturbations on the orbit of a test particle moving in a local Fermi frame induced therein by the cosmological tidal effects of the inhomogeneous Lemaitre-Tolman-Bondi (LTB) model. The LTB solution has recently attracted attention, among other things, as a possible explanation of the observed cosmic acceleration without resorting to dark energy. Then, we phenomenologically constrain both the parameters K_1 = -\ddot R/R and K_2 = -\ddot R^'/R^' of the LTB metric in the Fermi frame by using different kinds of solar system data. The corrections $Δ\dot\varpi$ to the standard Newtonian/Einsteinian precessions of the perihelia of the inner planets recently estimated with the EPM ephemerides, compared to our predictions for them, yield K_1 = (4+8) 10^-26 s^-2, K_2 = (3+7) 10^-23 s^-2. The residuals of the Cassini-based Earth-Saturn range, compared with the numerically integrated LTB range signature, allow to obtain K_1/2 = 10^-27 s^-2. The LTB-induced distortions of the orbit of a typical object of the Oort cloud with respect to the commonly accepted Newtonian picture, based on the observations of the comet showers from that remote region of the solar system, point towards K_1/2 <= 10^-30-10^-32 s^-2. Such figures have to be compared with those inferred from cosmological data which are of the order of K1 \approx K2 = -4 10^-36 s^-2.

description: Single-particle transport in disordered potentials is investigated on scales below the localization length. The dynamics on those scales is concretely analyzed for the 3-dimensional Anderson model with Gaussian on-site disorder. This analysis particularly includes the dependence of characteristic transport quantities on the amount of disorder and the energy interval, e.g., the mean free path which separates ballistic and diffusive transport regimes. For these regimes mean velocities, respectively diffusion constants are quantitatively given. By the use of the Boltzmann equation in the limit of weak disorder we reveal the known energy-dependencies of transport quantities. By an application of the time-convolutionless (TCL) projection operator technique in the limit of strong disorder we find evidence for much less pronounced energy dependencies. All our results are partially confirmed by the numerically exact solution of the time-dependent Schroedinger equation or by approximative numerical integrators. A comparison with other findings in the literature is additionally provided.

description: Nucleon drift and diffusion mechanisms in central collisions of asymmetric heavy-ions at near-barrier energies are investigated in the framework of a stochastic mean-field approach. Expressions for diffusion and drift coefficients for nucleon transfer deduced from the stochastic mean-field approach in the semiclassical approximation have similar forms familiar from the phenomenological nucleon exchange model. The variance of fragment mass distribution agrees with the empirical formula $σ^2_{AA}(t)= N_{\rm exc}(t)$. The comparison with the time-dependent Hartree-Fock calculations shows that, below barrier energies, the drift coefficient in the semiclassical approximation underestimates the mean number of nucleon transfer obtained in the quantal framework. Motion of the window in the dinuclear system has a significant effect on the nucleon transfer in asymmetric collisions.

description: The LMC star, SSTISAGE1C J050756.44-703453.9, was first noticed during a survey of EROS-2 lightcurves for stars with large irregular brightness variations typical of the R Coronae Borealis (RCB) class. However, the visible spectrum showing emission lines including the Balmer and Paschen series as well as many Fe II lines is emphatically not that of an RCB star. This star has all of the characteristics of a typical UX Ori star. It has a spectral type of approximately A2 and has excited an H II region in its vicinity. However, if it is an LMC member, then it is very luminous for a Herbig Ae/Be star. It shows irregular drops in brightness of up to 2 mag, and displays the reddening and "blueing" typical of this class of stars. Its spectrum, showing a combination of emission and absorption lines, is typical of a UX Ori star that is in a decline caused by obscuration from the circumstellar dust. SSTISAGE1C J050756.44-703453.9 has a strong IR excess and significant emission is present out to 500 micron. Monte Carlo radiative transfer modeling of the SED requires that SSTISAGE1C J050756.44-703453.9 has both a dusty disk as well as a large extended diffuse envelope to fit both the mid- and far-IR dust emission. This star is a new member of the UX Ori subclass of the Herbig Ae/Be stars and only the second such star to be discovered in the LMC.

Nonparametric estimation of genewise variance for microarray data

description: Estimation of genewise variance arises from two important applications in microarray data analysis: selecting significantly differentially expressed genes and validation tests for normalization of microarray data. We approach the problem by introducing a two-way nonparametric model, which is an extension of the famous Neyman--Scott model and is applicable beyond microarray data. The problem itself poses interesting challenges because the number of nuisance parameters is proportional to the sample size and it is not obvious how the variance function can be estimated when measurements are correlated. In such a high-dimensional nonparametric problem, we proposed two novel nonparametric estimators for genewise variance function and semiparametric estimators for measurement correlation, via solving a system of nonlinear equations. Their asymptotic normality is established. The finite sample property is demonstrated by simulation studies. The estimators also improve the power of the tests for detecting statistically differentially expressed genes. The methodology is illustrated by the data from microarray quality control (MAQC) project.

The perception of global motion in typical and atypical visual development
Creators: name: Meier, Kimberly
Publisher: name: University of British Columbia
Year: 2018

description: Sensitivity to motion information emerges early in life, but full maturation of motion perception can take many years. Reports on the age at which typically-developing children reach adult-like global motion perception have ranged from 3-14 years. There are also conflicting reports on whether people with amblyopia (a visual disorder that occurs when a young child experiences abnormal visual input to one eye for a prolonged period) show deficits on these tasks. This dissertation examines the spatio-temporal factors underlying immaturities and deficits in motion perception. I tested the hypothesis that perception of motion stimuli created with small spatial displacements would mature later than those created with large displacements; and as a consequence, children with amblyopia would show selective deficits for these small spatial displacements. First, I investigated typical maturation of motion perception across a range of stimulus parameters in people aged 7-30 years (Chapter 3). The youngest children performed similar to adults for large displacements, but mature performance was not reached until middle teenage years for small displacements. Second, I investigated performance for the same stimulus parameters in children with amblyopia (Chapter 4). Deficits were only present for parameters where healthy control children showed late maturation. Finally, I examined two factors that might account for the immaturities and deficits I found: spatial integration and eye stability. I determined that increasing the stimulus area had the same impact on coherence thresholds in 4-6 year-olds and adults (Chapter 5), suggesting children’s immature performance for small displacements was not restricted by spatial integration limitations at stages prior to motion processing. I also determined that eye stability had no relationship with performance in healthy adults (Chapter 6), indicating that poor fixational stability alone could not account for poor performance on a global motion task. This work contributes to a better understanding of how the developing brain is impacted by amblyopia, in turn providing insight into sensitive periods for typical visual development.
Non-variable cosmologically distant gamma-ray emitters as an imprint of propagation of ultra-high-energy protons

description: The acceleration cites of ultra-high-energy (UHE) protons can be traced by the footprint left by these particles propagating through cosmic microwave background (CMB) radiation. Secondary electrons produced in extended region of several tens of Mpc emit their energy via synchrotron radiation predominantly in the initial direction of the parent protons. It forms a non-variable and compact (almost point-like) source of high energy gamma rays. The importance of this effect is increased for cosmologically distant objects; because of severe energy losses, UHE protons cannot achieve us even in the case of extremely weak intergalactic magnetic fields. Moreover, at high redshifts the energy conversion from protons to secondary particles becomes significantly more effective due to the denser and more energetic CMB in the past. This increases the chances of UHE cosmic rays to be traced by the secondary synchrotron gamma radiation. We discuss the energy budget and the redshift dependence of the efficiency of energy transfer from UHE protons to synchrotron radiation. The angular and spectral distributions of radiation in the gamma- and X-ray energy bands are calculated and discussed in the context of their detectability by Fermi LAT and Chandra observatories.

description: The polymerization of actin filaments is coupled to the hydrolysis of adenosine triphosphate (ATP), which involves both the cleavage of ATP and the release of inorganic phosphate. We describe hydrolysis by a reduced two-state model with a cooperative cleavage mechanism, where the cleavage rate depends on the state of the neighboring actin protomer in a filament. We obtain theoretical predictions of experimentally accessible steady state quantities such as the size of the ATP-actin cap, the size distribution of ATP-actin islands, and the cleavage flux for cooperative cleavage mechanisms.

description: In this work the dispersion relation for surface waves on an impermeable boundary of a fully saturated poroelastic medium is investigated numerically in the whole range of frequencies. A linear model of a two-component poroelastic medium is used in the form proposed by K. Wilmański. Similarly to the classical Biot's model it is a continuum mechanical model but it is much simpler.
 In the whole range of frequencies there exist two modes of surface waves corresponding to the classical Rayleigh and Stoneley waves. The numerical results for velocities and attenuations of these waves are shown for different values of the bulk permeability coefficient in different ranges of frequencies.

description: We present the topological solutions of Einstein-dilaton gravity in the presence of a non-Abelian Yang-Mills field. In 4 dimensions, we consider the $So(3)$ and $So(2,1)$ semisimple group as the Yang-Mills gauge group, and introduce the black hole solutions with spherical and hyperbolic horizons, respectively. The solution in the absence of dilaton potential is asymptotically flat and exists only with spherical horizon. Contrary to the non-extreme Reissner-Nordstrom black hole, which has two horizons with a timelike and avoidable singularity, here the solution may present a black hole with a null and unavoidable singularity with only one horizon. In the presence of dilaton potential, the asymptotic behavior of the solutions is neither flat nor anti-de Sitter. These solutions contain a null and avoidable singularity, and may present a black hole with two horizons, an extreme black hole or a naked singularity. We also calculate the mass of the solutions through the use of a modified version of Brown and York formalism, and consider the first law of thermodynamics.

A simple protocol for the probability weights of the simulated tempering algorithm: applications to first-order phase transitions

description: The simulated tempering (ST) is an important method to deal with systems whose phase spaces are hard to sample ergodically. However, it uses accepting probabilities weights which often demand involving and time consuming calculations. Here it is shown that such weights are quite accurately obtained from the largest eigenvalue of the transfer matrix -- a quantity straightforward to compute from direct Monte Carlo simulations -- thus simplifying the algorithm implementation. As tests, different systems are considered, namely, Ising, Blume-Capel, Blume-Emery-Griffiths and Bell-Lavis liquid water models. In particular, we address first-order phase transition at low temperatures, a regime notoriously difficulty to simulate because the large free-energy barriers. The good results found (when compared with other well established approaches) suggest that the ST can be a valuable tool to address strong first-order phase transitions, a possibility still not well explored in the literature.

Moment-to-moment regulation of voltage-gated potassium channel function
Creators: name: Baronas, Victoria
Publisher: name: University of British Columbia
Year: 2018

description: Kv1.2 channels are prominently expressed in neurons where they help to set the threshold of action potential firing. While we have a good understanding of the mechanism of voltage sensing and gating, we have comparatively little information on the compendium of regulatory molecules that can impact Kv1.2 expression and function. Kv1.2 channels are subject to a unique mechanism of regulation whereby a train of brief, repetitive depolarizations elicit increasing amounts of current, a phenotype we term ‘use-dependent activation’. In heterologous cells expressing Kv1.2 and primary hippocampal cultures from rats, there is remarkable diversity in this phenotype. While use-dependent activation is absent in all other Kv1 channels, it persists in heteromeric channels containing at least one Kv1.2 subunit. Exposing cells expressing Kv1.2 to reducing conditions causes a dramatic shift in use-dependent activation where there is very little or no current elicited by the first pulse, but over the course of the train there is a hundred-fold or more increase in current. Additionally, reducing conditions cause a depolarizing shift in the activation curve of Kv1.2 by +64 mV. Taken together, we postulate that use-dependence arises from an extrinsic, redox-sensitive inhibitory regulator that associates with Kv1.2 preferentially in the closed, reduced state. We have identified a new regulator of Kv1.2 function, Slc7a5, an amino acid transporter. Co-expression of these two proteins decreases Kv1.2 expression and produces a hyperpolarizing shift of the activation and inactivation curves. Together these effects result in Kv1.2 channels being caught in an ‘inactivation trap’. These effects of Slc7a5 can be rescued by co-expressing a third protein, Slc3a2, which is known to heterodimerize with the Slc7a5 channel. Using BRET we show that Slc7a5 and Kv1.2 can be within 10 nm of each other. Other Kv1 channels we have tested (Kv1.1 and Kv1.5) are insensitive to the activation shift produced by Slc7a5, however Kv1.1 channels are exquisitely sensitive to current inhibition. Overall, the work in this thesis expands our knowledge of how Kv1.2 channels are regulated and opens the door to examining how these interactions contribute to normal neuronal function.

description: Due to the advances in hardware technology and increase in production of multimedia data in many applications, during the last decades, multimedia databases have become increasingly important. Contentbased multimedia retrieval is one of an important research area in the field of multimedia databases. Lots of research on this field has led to proposition of different kinds of index structures to support fast and efficient similarity search to retrieve multimedia data from these databases. Due to variety and plenty of proposed index structures, we suggest a systematic framework based on partitioning method used in these structures to classify multimedia index structures, and then we evaluated these structures based on important functional measures. We hope this proposed framework will lead to empirical and technical comparison of multimedia index structures and development of more efficient structures at future.

description: The important direction in Low Power research is associated with the usage of ferroelectric materials to obtain the negative differential capacitance. This talk discusses the development of capacitor models providing the analysis of ferroelectric circuits by SPICE-like simulator. The separate models for standalone capacitors are proposed, which are determined by the dependencies "charge on voltage and "voltage on charge". The equivalent nonsingular subcircuit is presented that provides the series connection of any number of nonlinear capacitors with floating nodes. The models take into account the trapped charges in floating nodes. The subcircuit for star connection of arbitrary capacitors is also described. The results of SPICE simulations of some ferroelectric circuit configurations are given to show the efficiency of the proposed approach.

description: In this article we present the first and second order numerical schemes for the solution of initial value problems of the Boltzmann-Peierls equation (BPE). We also modify the numerical schemes for the solution of initial and boundary value problems (IBVP) of its derived hyperbolic moment system. BPE is an integro-differential equation which describes the evolution of heat in crystalline solids at very low temperatures. The BPE describes the evolution of the phase density of a phonon gas. The corresponding entropy density is given by the entropy density of a Bose-gas. We derive a reduced three-dimensional kinetic equation which has a much simpler structure than the original BPE, while it still retain all the properties of the original BPE. Using special coordinates, we get a further reduction of the kinetic equation in one space dimension. We introduce the discrete-velocity model of the reduce BPE in one space dimension. This discrete-velocity model can be discretized in space and time by using finite volume schemes. We derive both first and second order explicit upwind and central schemes for the discrete-velocity kinetic equation as well as for the derived moment system. We use the kinetic approach in order to prescribe boundary conditions for the IBVP of the moment system. Several numerical test cases are considered in order to validate the theory.

Using a sample of p-pbar collisions at sqrt{s}=1.96 TeV corresponding to 5.9 fb-1 of integrated luminosity collected with the CDFII detector at the Fermilab Tevatron, we search for new B0_s decay modes in a sample of events containing J/psi to mu+ mu- decays. We reconstruct a B0_s to J/psi K*(892)0 signal with K^*(892)0 to K+ pi-, observing a yield of 151 +/- 25 events with a statistical significance of 8.0 sigma. We also reconstruct a B0_s to J/psi K0_S signal with K0_S to pi+ pi-, observing a yield of 64 +/- 14 events with a statistical significance of 7.2 sigma. From these yields, we extract the branching ratios B(B0_s -> J/psi K*(892)0)= (8.3 +/- 3.8) x 10{-5} and B(B0_s -> J/psi K0)= (3.5 +/- 0.8) x 10{-5}, where statistical, systematic and fragmentation fraction uncertainties are included in the combined uncertainty.

description: When two types of side chains (A,B) are densely grafted to a (stiff) backbone and the resulting bottle-brush polymer is in a solution under poor solvent conditions, an incompatibility between A and B leads to microphase separation in the resulting cylindrical brush. The possible types of ordering are reminiscent of the ordering of block copolymers in cylindrical confinement. Starting from this analogy, Leibler's theory of microphase separation in block copolymer melts is generalized to derive a description of the system in the weak segregation limit. Also molecular dynamics simulation results of a corresponding coarse-grained bead-spring model are presented. Using side chain lengths up to N = 50 effective monomers, the ratio of the Lennard-Jones energy parameter between unlike monomers $(ε_{AB})$ and monomers of the same kind $(ε_{AA} = ε_{BB})$ is varied. Various correlation functions are analyzed to study the conditions when (local) Janus cylinder-type ordering and when (local) microphase separation in the direction along the cylinder axis occurs. Both the analytical theory and the simulations give evidence for short range order due to a tendency towards microphase separation in the axial direction, with a wavelength proportional to the side chain gyration radius, irrespective of temperature and grafting density, for a wide range of these parameters.

Compact Modelling of FDSOI Transistors Down to Cryogenic Temperatures

Publisher: name: Zenodo
Year: 2021

description: With the emergence of quantum computing, low temperature operational CMOS transistors (operating around T= 4K) are needed for the control/readout of the Qubits. In low temperature operation, FDSOI MOSFET provides several advantages, such as an ideal subthreshold swing, improved transport properties resulting in higher operational speed, making it a promising candidate for the control/readout electronics needed around Qubits. Whereas many works present modelling results of FDSOI/bulk transistor inversion charge and drain current, most of them where based on models that are not built for cryogenic operation. On the contrary, our model stands as a fully-built model dedicated for these operation conditions. Our work presents a long channel current compact model valid down to deep cryogenic temperatures and able to deal with dual channel operation.

There is a set of technical tools that are at the very heart of understanding analytical properties of essentially every spectral zeta function. Those tools are introduced using the well-studied examples of the Hurwitz, Epstein and Barnes zeta function. It is explained how these different examples of zeta functions can all be thought of as being generated by the same mechanism, namely they all result from eigenvalues of suitable (partial) differential operators. It is this relation with partial differential operators that provides the motivation for analyzing the zeta functions considered in these lectures. Motivations come for example from the questions "Can one hear the shape of a drum?" and "What does the Casimir effect know about a boundary?". Finally "What does a Bose gas know about its container?"

description: One of the topics of research in ANIMA is the effectiveness of the use of a Virtual reality device for credible communication and engagement with people around airports. As input to this kind of device one needs realistic noise signatures.

For existing aircraft, experimental data (aircraft noise recordings) can be used. For novel aircraft however, only existing on the drawing board, such experimental data is obviously not available. To fill this gap, noise predictions will be made with the Noise Reduction Solutions Simulator, which is part of the Virtual Community Toolchain that is being developed in ANIMA WP4. This Simulator will be capable of predicting noise spectra of novel aircraft including noise reduction technology concepts, which, in turn, can be fed to noise synthesis tools (in this report also called auralization tools) to create realistic noise signatures. This combination of noise prediction and noise synthesis will be called auralization toolchain in the following.

At present the Noise Reduction Solutions Simulator is still under development and no reliable noise predictions can yet be made. However, an important aspect of the auralization toolchain can already be tested: the interface between the Simulator and noise synthesis tools. The goal is to have a noise prediction tool that can be plugged to any available noise synthesis tool.

This report describes the methodology used in the Simulator, comprised of two tools, FRIDA and SOPRANO, to get noise spectra from data characterizing an aircraft flight. Additionally, a representative sample datafile is described, with which this interface test can be performed, and which will allow for an early detection of any issues interfacing the components.
On the Lagrangian formulation of multidimensionally consistent systems

description: Multidimensional consistency has emerged as a key integrability property for partial difference equations (P$Δ$Es) defined on the "space-time" lattice. It has led, among other major insights, to a classification of scalar affine-linear quadrilateral P$Δ$Es possessing this property, leading to the so-called ABS list. Recently, a new variational principle has been proposed that describes the multidimensional consistency in terms of discrete Lagrangian multi-forms. This description is based on a fundamental and highly nontrivial property of Lagrangians for those integrable lattice equations, namely the fact that on the solutions of the corresponding P$Δ$E the Lagrange forms are closed, i.e. they obey a {\it closure relation}. Here we extend those results to the continuous case: it is known that associated with the integrable P$Δ$Es there exist systems of PDEs, in fact differential equations with regard to the parameters of the lattice as independent variables, which equally possess the property of multidimensional consistency. In this paper we establish a universal Lagrange structure for affine-linear quad-lattices alongside a universal Lagrange multi-form structure for the corresponding continuous PDEs, and we show that the Lagrange forms possess the closure property.

Milton and Catholicism
Creators: name: Corthell, Ronald
Publisher: name: University of Notre Dame
Year: 2023

description: \u000aThis collection of original essays by literary critics and historians analyzes a wide range of Milton's writing, from his early poetry, through his mid-century political prose, to _De Doctrina Christiana_, which was unpublished in his lifetime, and finally to his last and greatest poems. The contributors investigate the rich variety of approaches to Milton's engagement with Catholicism and its relationship to reformed religion. The essays address latent tensions and contradictions, explore the nuances of Milton's relationship to the easy commonplaces of Protestant compatriots, and disclose the polemical strategies and tactics that often shape that engagement.\u000a \u000aThe contributors link Milton and Catholicism with early modern confessional conflicts between Catholics and Protestants that in turn led to new models and standards of authority, scholarship, and interiority. In Milton's case, he deployed anti-Catholicism as a rhetorical device and the negative example out of which Protestants could shape their identity. The contributors argue that Milton's anti-Catholicism aligns with his understanding of inwardness and conscience and illuminates one of the central conflicts between Catholics and Protestants in the period. Building on recent scholarship on Catholic and anti-Catholic discourses over the English Tudor and Stuart period, new understandings of martyrdom, and scholarship on Catholic women, _Milton and Catholicism_, provides a diverse and multifaceted investigation into a complex and little-explored field in Milton studies.\u000a \u000aContributors: Alastair Bellany, Thomas Cogswell, Thomas N.

Time-convolutionless master equation for quantum dots: Perturbative expansion to arbitrary order

description: The master equation describing the non-equilibrium dynamics of a quantum dot coupled to metallic leads is considered. Employing a superoperator approach, we derive an exact time-convolutionless master equation for the probabilities of dot states, i.e., a time-convolutionless Pauli master equation. The generator of this master equation is derived order by order in the hybridization between dot and leads. Although the generator turns out to be closely related to the T-matrix expressions for the transition rates, which are plagued by divergences, in the time-convolutionless generator all divergences cancel order by order. The time-convolutionless and T-matrix master equations are contrasted to the Nakajima-Zwanzig version. The absence of divergences in the Nakajima-Zwanzig master equation due to the nonexistence of secular reducible contributions becomes rather transparent in our approach, which explicitly projects out these contributions. We also show that the time-convolutionless generator contains the generator of the Nakajima-Zwanzig master equation in the Markov approximation plus corrections, which we make explicit. Furthermore, it is shown that the stationary solutions of the time-convolutionless and the Nakajima-Zwanzig master equations are identical. However, this identity neither extends to perturbative expansions truncated at finite order nor to dynamical solutions. We discuss the conditions under which the Nakajima-Zwanzig-Markov master equation nevertheless yields good results.

description: A growing number of applications that generate massive streams of data need intelligent data processing and online analysis. Real-time surveillance systems, telecommunication systems, sensor networks and other dynamic environments are such examples. The imminent need for turning such data into useful information and knowledge augments the development of systems, algorithms and frameworks that address streaming challenges. The storage, querying and mining of such data sets are highly computationally challenging tasks. Mining data streams is concerned with extracting knowledge structures represented in models and patterns in non stopping streams of information. Generally, two main challenges are designing fast mining methods for data streams and need to promptly detect changing concepts and data distribution because of highly dynamic nature of data streams. The goal of this article is to analyze and classify the application of diverse data mining techniques in different challenges of data stream mining. In this paper, we present the theoretical foundations of data stream analysis and propose an analytical framework for data stream mining techniques.
