Leveraging students' handwritten notes to link to watched instructional videos
Creators: name: Jaddigadde Srinivasa, Ranjitha
Publisher: name: University of British Columbia
Year: 2021

description: Handwritten note-taking with pen and paper is still the preferred medium to achieve information seeking and comprehension from diverse learning objects. But students, especially in video-based learning settings, exercise laborious practices to re-find the corresponding video context when reviewing notes. We propose the orchestration of students' handwritten notebook content as interoperable links to retrieve previously watched instructional videos. This work articulates the research objectives in two phases. In phase 1, we analyzed the characteristic features of notebook content of watched videos. And, in phase 2, we investigated student expectations and requirements of the proposed video retrieval system. Analysis of quality handwritten notebook samples and the related video materials in a lab study with ten engineering students revealed distinctive characteristic representations of note content such as text, formula, figures, and chiefly a hybrid of all the 3. A box plot interpretation of notes and the watched video content confirmed that at least 75% of the identified note samples demonstrated a verbatim overlap of 50% or more with the related video content, hinting at its potential use as a query artifact. Additionally, the video references to collected note samples exhibited referencing at three temporal levels: point, interval, and whole video. A 12-student lab study indicated higher satisfaction for video matches returned at the `interval' level and showcased students' existing workarounds for linking back to videos. Overall, students rated a positive Mean score for the system's usability to re-find note-specific video context. A medium-fidelity prototype was built, using off-the-shelf computer vision algorithms, to deduce technology requirements associated with the proposed approach. When tested on the 181 identified note samples, the prototype system matched 77.5% of the samples to corresponding watched videos. The proposed method worked exceptionally well to find suitable videos for textual notes --- yielding a 98% accuracy. The note content overlap with the video results further highlights the fragmented nature of the evaluated accuracy across all three temporal levels. Overall, the presented work ascertains the prospect of augmenting prevalent Personalized learning (PL) strategies, such as handwriting notes for future reference, to easily re-find and connect to the watched videos.

description: When a Mott metal-insulator transition is inhibited by a small amount of disorder in the layered dichalcogenide 1T-TaS$_2$, an inhomogeneous superconducting state arises below T=2.1 K, and coexists with a nearly-commensurate charge-density-wave. By angle-resolved photoelectron spectroscopy (ARPES) we show that it emerges from a bad metal state with strongly damped quasiparticles. Superconductivity is almost entirely suppressed by an external magnetic field of 0.1 T.

description: We give a comprehensive review of the quantization of midisuperspace models. Though the main focus of the paper is on quantum aspects, we also provide an introduction to several classical points related to the definition of these models. We cover some important issues, in particular, the use of the principle of symmetric criticality as a very useful tool to obtain the required Hamiltonian formulations. Two main types of reductions are discussed: those involving metrics with two Killing vector fields and spherically symmetric models. We also review the more general models obtained by coupling matter fields to these systems. Throughout the paper we give separate discussions for standard quantizations using geometrodynamical variables and those relying on loop quantum gravity inspired methods.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: This paper continues a previous study of neutron stars with positive polar-cap corotational charge density in which free emission of ions maintains the surface electric-field boundary condition E.B = 0. The composition of the accelerated plasma on any subset of open magnetic flux-lines above the polar cap alternates between two states; either protons or positrons and ions, of which the proton state cannot support electron-positron pair creation at higher altitudes. The two states coexist at any instant of time above different moving elements of area on the polar cap and provide a physically consistent basis for a description of pulse nulls and sub-pulse drift. In the latter case, it is shown that the band separation P3 is determined not by the ExB drift velocity, as is generally assumed, but by the diffusion time for protons produced in reverse-electron showers to reach the region of the atmosphere from which they are accelerated. An initial comparison is made with the survey of sub-pulse drift published by Weltevrede et al.

description: We present the results of a multi-component synthetic spectral analysis of the archival far ultraviolet spectra of several key nova-like variables including members of the SW Sex, RW Tri, UX UMa and VY Scl subclasses: KR Aur, RW Tri, V825 Her, V795 Her, BP Lyn, V425 Cas and HL Aqr. Accretion rates as well as the possible flux contribution of the accreting white dwarf are included in our analysis. Except for RW Tri which has a reliable trigonometric parallax, we computed the distances to the nova-like systems using the method of Knigge (2006). Our analysis of seven archival IUE spectra of RW Tri at its parallax distance of 341 pc consistently indicates a low mass (0.4Msun) white dwarf and an average accretion rate, 6.3 E-9Msun/yr. For KR Aur, we estimate that the white dwarf has Teff=29,000K, log g = 8.4 and contributes 18% of the FUV flux while an accretion disk with accretion rate of 3 E-10Msun/yr at an inclination of 41 degrees, contributes the remainder. We find that an accretion disk dominates the far UV spectrum of V425 Cas but a white dwarf contributes non-negligibly with approximately 18% of the FUV flux. For the two high state nova-likes, HL Aqr and V825 Her, their accretion disks totally dominate with 1 E-9Msun/yr and 3 E-9Msun/yr, respectively. For BP Lyn we find an accretion rate of 1 E-8Msun/yr while for V795 Her, we find an accretion rate of 1 E-10Msun/yr. We discuss the implications of our results for the evolutionary status of nova-like variables.

description: Negli ultimi anni la robotica educativa si sta gradualmente e inerosabilmente affermando nella scuola dell’obbligo ticinese come artefatto d’insegnamento/apprendimento nella didattica della matematica e come occasione per lo sviluppo di competenze trasversali nei contesti di formazione generale. In questo lavoro di ricerca-azione qualitativa si sono voluti osservare i processi comunicativi interpersonali all’interno di modalità didattiche di tipo cooperativo rivolte ad allievi di una classe di prima media, ai fini di verificare se la motivazione e la curiosità degli allievi possano essere stimolate in un contesto di apprendimento situato nel quale gli allievi sono chiamati a scoprire, modellizzare e comunicare il funzionamento e le potenzialtà di un artefatto robotico (Thymio II). L’itinerario ha visto l’esplorazione a coppie dell’artefatto, lo scambio con un’altra classe prima, la programmazione del robot e l’invenzione di problemi applicando il pensiero computazionale e la logica evento-azione. Attraverso l’analisi della comunicazione verbale e non verbale, della produzione scritta degli allievi e dei questionari da loro compilati, si è potuto verificare chel’artefatto robotico è un mediatore comunicativo importante nella relazione e un valido mezzo per catalizzare e sviluppare le competenze socio-relazionali degli allievi in ottica cooperativa ai fini dello svolgimento funzionale di un compito complesso.

The health-promoting potential of occupations : an exploratory study of adults with and without inflammatory arthritis
Creators: name: To-Miles, Flora
Publisher: name: University of British Columbia
Year: 2021

description: Introduction: Inflammatory arthritis (IA) can limit everyday occupations, yet engaging in valued occupations is believed to promote health. This dissertation explores the relationship between occupation and health in adults with IA and a healthy comparison (HC) group, and the impact of public health restrictions on occupation and health during the first wave of the COVID-19 pandemic. Methods: A cross-sectional design was employed with participants recruited through community advertising. Occupations were elicited and occupational characteristics measured using Personal Projects Analysis; and aspects of health assessed using the SF-36 Health Survey (Physical and Mental Component Scores), Occupational Balance Questionnaire, Satisfaction with Life Scale, and telomere length (from dried blood spots). During the first “stay home” phase of the pandemic, all self-report measures were repeated online to compare with pre-pandemic ratings. Data were analyzed with content analyses, Chi-square tests, t-tests, linear regressions, and ANCOVAs. Results: 143 adults (76 HC, 67 IA) participated in the cross-sectional study; a subset of 71 (37 HC, 34 IA) participated in the pandemic before-and-after study. Participants engaged in six major categories of occupations related to health, leisure, home, community, relationships, and life planning. These categories did not differ between IA and HC groups. The IA group rated occupational characteristics higher than the HC group, with between-group differences in three of the 19 characteristics after controlling for demographic covariates. Different occupational characteristics were associated with physical health for the two groups; among the more salient characteristics were the perceived Difficulty, Importance, Stress, Progress, Others’ view, and Control attributed to one’s occupations. Occupational balance was higher in the HC group than the IA group, but not statistically significant when adjusted for physical health. There was no between-group difference in telomere length, or associations between occupational characteristics and telomere length. Mental health scores decreased compared to pre-pandemic ratings in the HC group only, and the IA group engaged in fewer social occupations than the HC group. Conclusion: These findings help fill a gap in the literature with a nuanced understanding of the association between occupation and health, which may inform recommendations on the kinds of occupations likely to promote health.

description: The ProSUM project delivered the first Urban Mine Knowledge Data Platform, accessible at http://www.urbanmineplatform.eu/, a centralised database of all available data and information on arisings, stocks, flows and treatment of waste electrical and electronic equipment (WEEE), end-of-life vehicles (ELVs), batteries and mining wastes.

The purpose of this report is to describe the results of the assessment of the amount (stocks and flows) of products in households and businesses. Task 3.1 takes an inventory of the data sources available in line with, and structured according to, the classifications and harmonisation produced in Deliverable 5.3 “Review and Harmonisation of Data”. Since data on stocks and flows is often from various diverse sources, the classification system developed in D5.3 is essential in structuring all available data sources. In addition to this, geographic and demographic information has been reviewed from EU wide statistical databases. The inventory has been produced by screening data from publicly available sources, and specific national sources and studies e.g. published academic literature, technical reports, national producer registries, and consumer surveys indicating stock levels for products present in households and businesses. Furthermore, data from other EU projects, other quantification studies like those performed in the Ecodesign Directive (for Energy related/ using Products) studies, commercially available market research data (where available and affordable) plus information from EU wide associations such as: CECED and Digital Europe for EEE; Recharge/Eucobat for batteries; and the European Automobile Manufacturer’s Association (ACEA) for vehicles.
La relazione tra allievi e adulti nel contesto scolastico del primo biennio di scuola media

description: Il presente lavoro di diploma ha come obiettivo di indagare la relazione che si sviluppa a scuola tra gli allievi e gli adulti che li circondano. I dati – raccolti tramite un questionario adattato alla realtà ticinese a partire da un modello già utilizzato nella provincia canadese della British Columbia e che è stato distribuito a oltre 600 allievi del ciclo d’osservazione della scuola media – permettono di tracciare un ritratto abbastanza esaustivo in merito alle sfaccettature che caratterizzano la relazione tra allievi e adulti nel contesto scolastico: l’analisi mostra come per una maggioranza di allievi esistano delle figure di riferimento considerate importanti, ma anche come ci siano ampi margini di miglioramento che andranno sfruttati per assicurare ai ragazzi un ambiente scolastico sempre più attento alle loro esigenze e al sostegno emotivo di cui essi necessitano. Analizzando più nel dettaglio le risposte, emergono differenze tra maschi e femmine (con queste ultime che sembrano avere una percezione più positiva delle figure adulte); gli allievi che non sono di madrelingua italiana, inoltre, parrebbero percepire in modo più positivo, rispetto ai compagni di origine indigena, il sostegno e l’ascolto che offrono loro gli adulti. Tutti i risultati, infine, non fanno che confermare da una parte la centralità della dimensione socioemotiva nell’ambiente scolastico e dall’altra gli ampi margini di miglioramento che in ogni campo analizzato dovranno ancora essere sfruttati.

description: We report on the observation of unusually strong interactions in a thermal mixture of ultracold atoms which cause a significant modification of the spatial distribution. A mixture of $^{87}$Rb and $^{174}$Yb with a temperature of a few $μ$K is prepared in a hybrid trap consisting of a bichromatic optical potential superimposed on a magnetic trap. For suitable trap parameters and temperatures, a spatial separation of the two species is observed. We infer that the separation is driven by a large interaction strength between $^{174}$Yb and $^{87}$Rb accompanied by a large three-body recombination rate. Based on this assumption we have developed a diffusion model which reproduces our observations.

description: Unsupervised two-view learning, or detection of dependencies between two paired data sets, is typically done by some variant of canonical correlation analysis (CCA). CCA searches for a linear projection for each view, such that the correlations between the projections are maximized. The solution is invariant to any linear transformation of either or both of the views; for tasks with small sample size such flexibility implies overfitting, which is even worse for more flexible nonparametric or kernel-based dependency discovery methods. We develop variants which reduce the degrees of freedom by assuming constraints on similarity of the projections in the two views. A particular example is provided by a cancer gene discovery application where chromosomal distance affects the dependencies between gene copy number and activity levels. Similarity constraints are shown to improve detection performance of known cancer genes.

description: Quantification of historical sociological processes have recently gained attention among theoreticians in the effort of providing a solid theoretical understanding of the behaviors and regularities present in sociopolitical dynamics. Here we present a reliability theory of polity processes with emphases on individual political dynamics of African countries. We found that the structural properties of polity failure rates successfully capture the risk of political vulnerability and instabilities in which 87.50%, 75%, 71.43%, and 0% of the countries with monotonically increasing, unimodal, U-shaped and monotonically decreasing polity failure rates, respectively, have high level of state fragility indices. The quasi-U-shape relationship between average polity duration and regime types corroborates historical precedents and explains the stability of the autocracies and democracies.

Generalized DC and AC Josephson effects in antiferromagnets and in antiferromagnetic d-wave superconductors

description: The Josephson effect is generally described as Cooper pair tunneling, but it can also be understood in a more general context. The DC Josephson effect is the pseudo-Goldstone boson of two coupled systems with a broken continuous abelian U(1) symmetry. Hence, an analog should exist for systems with broken continuous non-Abelian symmetries. To exhibit the generality of the phenomenon and make predictions from a realistic model, we study tunneling between antiferromagnets and also between antiferromagnetic d-wave superconductors. Performing a calculation analogous to that of Ambegaokar and Baratoff for the Josephson junction, we find an equilibrium current of the staggered magnetization through the junction that, in antiferromagnets, is proportional to s_L X s_R where s_L and s_R are the Neel vectors on either sides of the junction. Microscopically, this effect exists because of the coherent tunneling of spin-one particle-hole pairs. In the presence of a magnetic field which is different on either sides of the junction, we find an analog of the AC Josephson effect where the angle between Neel vectors depends on time. In the case of antiferromagnetic d-wave superconductors we predict that there is a contribution to the critical current that depends on the antiferromagnetic order and a contribution to the spin-critical current that depends on superconducting order. The latter contributions come from tunneling of the triplet Cooper pair that is necessarily present in the ground state of an antiferromagnetic d-wave superconductor. All these effects appear to leading order in the square of the tunneling matrix elements.

Ferroelectricity in biological building blocks: slipping on a banana peel?

Subjects: subject: Biological sciences

description: Ferroelectricity in biological system has been anticipated both theoretically and experimentally over the past few decades. Claims of ferroelectricity in biological systems have given rise to confusion and methodological controversy. Over the years, a “loop” of induced polarization in response to a varying applied electrical field and a consequent polarization reversal has prompted many researchers to claim ferroelectricity in biological structures and their building blocks. Other observers were skeptical about the methodology adopted in generating the data and questioned the validity of the claimed ferroelectricity as such, “loop” can also be obtained from linear capacitors. In a paper with somewhat tongue-in-cheek title, Jim Scott showed that ordinary banana peels could exhibit closed loops of electrical charge which closely resemble and thus could be misinterpreted as ferroelectric hysteresis loops in barium sodium niobate, BNN paraphrasing it as “banana”. In this paper, we critically review ferroelectricity in biological system and argue that knowing the molecular and crystalline structure of biological building blocks and experimenting on such building blocks may be the way forward in revealing the “true” nature of ferroelectricity in biological systems

Dirichlet mean identities and laws of a class of subordinators

Subjects: subject: Statistics Theory (math.ST)

description: An interesting line of research is the investigation of the laws of random variables known as Dirichlet means. However, there is not much information on interrelationships between different Dirichlet means. Here, we introduce two distributional operations, one of which consists of multiplying a mean functional by an independent beta random variable, the other being an operation involving an exponential change of measure. These operations identify relationships between different means and their densities. This allows one to use the often considerable analytic work on obtaining results for one Dirichlet mean to obtain results for an entire family of otherwise seemingly unrelated Dirichlet means. Additionally, it allows one to obtain explicit densities for the related class of random variables that have generalized gamma convolution distributions and the finite-dimensional distribution of their associated Lévy processes. The importance of this latter statement is that Lévy processes now commonly appear in a variety of applications in probability and statistics, but there are relatively few cases where the relevant densities have been described explicitly. We demonstrate how the technique allows one to obtain the finite-dimensional distribution of several interesting subordinators which have recently appeared in the literature.

description: Composing Web services is a convenient means of dealing with complex requests. However, the number of Web services on the Internet is increasing. This explains the growing interest in composing Web services automatically. Nevertheless, the Web services' semantics is necessary for any dynamic composition process. In this article, we present an MDA approach to develop and compose SAWSDL semantic Web services. To model Web services, we use a UML profile which is independent of the description standards. The SAWSDL interface files are generated by using transformation rules. To model the behavior of a composite Web service and generate its executable BPEL file, we use the BPMN notation in a platform of modeling and implementing business process. The main contribution of this work is the easy and extensible solution to a model-driven development of the semantic atomic and composite Web services.

description: Writings by 16th to 18th century Lutheran missionaries on the indigenous Sámi peoples of northern Scandinavia show a strong tendency to characterize all aspects of traditional Sámi spirituality as demonic “superstition” that posed a real, existential threat to the kingdoms of Denmark-Norway and Sweden’s status as Lutheran Christian kingdoms following the Reformation. These beliefs and practices, in their view, therefore needed to be stamped out. This dissertations views the theological rhetoric of these missionary works through the lens of “superstition” (i.e. illicit religion) vs. “religion” (i.e. licit religion) as elucidated by Patristic authors such as Tertullian and Augustine, as well as the more recent theoretical model of “syncretism” (i.e. religion blendings) vs. “anti-syncretism” (i.e. the backlash against religious blendings) from scholars such as Meyer and van der Leeuw. I argue that indigenous spirituality served as a canvas upon which these Lutheran missionaries cast many of their own theological uncertainties regarding the fight against illicit religion which had begun centuries earlier with the Lutheran Reformation. Chapter 1 provides an overview of relevant research on historical missionary contact with the Sámi and a summary of important scholarship on the Western study of indigenous spirituality in general. Chapter 2 focuses on the most salient Lutheran missionary authors of this period. It situates these authors’ works within their historical contexts, and presents the writers’ depictions of Sámi spirituality. Chapter 3 outlines the methodological considerations of both of the theoretical frameworks used in this dissertation to analyze missionary sources on Sámi spirituality. Chapter 4 uses the theoretical frameworks as outlined in the previous chapter to analyze the relevant missionary works. By doing this, it shows that almost all of these missionary writers categorized indigenous Sámi spirituality as “superstition” and strongly condemned any perceived syncretistic blendings. Chapter 5 is a comparative analysis of German Lutheran missionaries in Papua New Guinea in the 20th century. This chapter provides a similar analysis of a Lutheran mission in a different part of the world and in a different time that bears strong similarities to the Scandinavian Lutheran missions to the Sámi. This dissertation uses these models of “superstition” vs. “religion” and “syncretism” vs. “anti-syncretism” to track how missionary portrayals of Sámi spirituality and the conversion process changed throughout the course of missionary activity, thereby showing how changing theological attitudes over from the 17th through the 20th century affected missionary attitudes.
Patterns of genomic differentiation and hybridization between two merging Emberizidae species implicate a sex chromosome inversion in plumage variation
Creators: name: Nikelski, Ellen Glyn Marshall
Publisher: name: University of British Columbia
Year: 2021

description: Hybrid zones offer researchers the opportunity to investigate how evolutionary processes interact to drive speciation forward. However, in these areas where genetic divergence competes against gene flow, speciation and population merging are both possible with the outcome dependent on the strength of reproductive barriers between groups. The yellowhammer (Emberiza citrinella) and pine bunting (Emberiza leucocephalos) are Palearctic songbirds with highly divergent plumage patterns. Despite their differences, these taxa hybridize extensively and show negligible differentiation in their mitochondrial genomes. These observations create a conflicting picture of the state of reproductive barriers between groups, raising the question whether yellowhammers and pine buntings are actually separate species. In this thesis, I examine patterns of genetic variation among phenotypically pure and hybrid individuals to assess the strength of reproductive isolation between taxa. I hypothesize that, unlike mitochondrial differentiation, nuclear differentiation will be moderate and that patterns of divergence will reflect some weak reproductive isolation between groups. I find that, in allopatry, yellowhammers and pine buntings separate into distinct genetic clusters based on an island of differentiation on the Z chromosome. Yet, in other parts of the genome, I find evidence of past mitonuclear gene introgression. In sympatry, I report a breakdown of allopatric genetic clusters driven by extensive interbreeding. These findings combined with the high number of late generation hybrids identified within the sympatric zone suggest that reproductive barriers are weak between taxa. Interestingly, I further find low recombination within the island of differentiation identified between allopatric populations implying that this region may house a chromosomal inversion. The inversion is highly associated with plumage variation and may be responsible for the maintenance of parental phenotypes within the sympatric zone. Because reproductive barriers are weak, it is likely that hybridization will continue between yellowhammers and pine buntings potentially leading to the merging of these groups, but that the putative inversion could preserve parental plumage phenotypes within this single species. Retention of such variation would increase the evolvability of the system such that the population could be safeguarded from extinction or, if evolutionary pressures change, could diverge again and move towards speciation.

description: We study the spin quantum Hall effect and transitions between Hall plateaus in quasi two-dimensional network models consisting of several coupled layers. Systems exhibiting the spin quantum Hall effect belong to class C in the symmetry classification for Anderson localisation, and for network models in this class there is an established mapping between the quantum problem and a classical one involving random walks. This mapping permits numerical studies of plateau transitions in much larger samples than for other symmetry classes, and we use it to examine localisation in systems consisting of $n$ weakly coupled layers. Standard scaling ideas lead one to expect $n$ distinct plateau transitions, but in the case of the unitary symmetry class this conclusion has been questioned. Focussing on a two-layer model, we demonstrate that there are two separate plateau transitions, with the same critical properties as in a single-layer model, even for very weak interlayer coupling.

description: We consider the supercritical finite-range random connection model where the points $x,y$ of a homogeneous planar Poisson process are connected with probability $f(|y-x|)$ for a given $f$. Performing percolation on the resulting graph, we show that the critical probabilities for site and bond percolation satisfy the strict inequality $p_c^{\rm site} > p_c^{\rm bond}$. We also show that reducing the connection function $f$ strictly increases the critical Poisson intensity. Finally, we deduce that performing a spreading transformation on $f$ (thereby allowing connections over greater distances but with lower probabilities, leaving average degrees unchanged) {\em strictly} reduces the critical Poisson intensity. This is of practical relevance, indicating that in many real networks it is in principle possible to exploit the presence of spread-out, long range connections, to achieve connectivity at a strictly lower density value.

description: Die Absatzzahlen für Wärmepumpen sind in den vergangenen Jahren deutlich gestiegen und nicht zuletzt auf Grund der staatliche Förderung rechnet die Branche für 2022 mit einem Wachstumsschub.Andererseits gibt es physikalisch und technische Rahmenbedingungen, die beachtet werden müssen, damit es nach einem Austausch nicht zu unerwünschten Kostensteigerungen kommt. In diesem Vortrag geht es um die physikalischen Funktionsweisen der verschiedenen Wärmepumpen und was verschiedene Kennzahlen (z.B. COP, Schalldruckpegel, ...) bedeuten. Ob und wenn ja welches konkrete Modell im Einzelfall zum Einsatz kommen könnte, muss aber immer individuell untersucht werden.

description: We present the analysis of the CoRoT star 105288363, a new Blazhko RR Lyrae star of type RRab (f0 = 1.7623 c/d), observed with the CoRoT space craft during the second long run in direction of the galactic center (LRc02, time base 145 d). The CoRoT data are characterized by an excellent time sampling and a low noise amplitude of 0.07 mmag in the 2-12 c/d range and allow us to study not only the fine details of the variability of the star but also long-term changes in the pulsation behaviour and the stability of the Blazhko cycle. We use, among other methods, standard Fourier analysis techniques and O-C diagrams to investigate the pulsational behavior of the Blazhko star 105288363. In addition to the frequency pattern expected for a Blazhko RR Lyrae star, we find an independent mode (f1 = 2.984 c/d) showing a f0/f1 ratio of 0.59 which is similar to that observed in other Blazhko RR Lyrae stars. The bump and hump phenomena are also analysed, with their variations over the Blazhko cycle. We carefully investigated the strong cycle-to-cycle changes in the Blazhko modulation (PB = 35.6 d), which seem to happen independently and partly diametrically in the amplitude and the phase modulation. Furthermore, the phasing between the two types of modulation is found to change during the course of the observations.

description: Handwriting Recognition enables a person to scribble something on a piece of paper and then convert it into text. If we look into the practical reality there are enumerable styles in which a character may be written. These styles can be self combined to generate more styles. Even if a small child knows the basic styles a character can be written, he would be able to recognize characters written in styles intermediate between them or formed by their mixture. This motivates the use of Genetic Algorithms for the problem. In order to prove this, we made a pool of images of characters. We converted them to graphs. The graph of every character was intermixed to generate styles intermediate between the styles of parent character. Character recognition involved the matching of the graph generated from the unknown character image with the graphs generated by mixing. Using this method we received an accuracy of 98.44%.
