**Thesis title:**Étude de situations scolaires des premiers enseignements du nombre et de la numération. Relations entre divers caractères de ses situations et le sens, la compréhension de l'apprentissage de ces notions [Study of school situations of the first teaching of number and numeration. Relationships between diverse characters of these situations and the meaning, the understanding of the learning of these notions].

**University:**Université Bordeaux 1 (Bordeaux, France).

**Advisor:**Guy Brousseau.

**Note:**Abstract of thesis. Two didactic transpositions of the concept of numeration emerge through the study of teaching methods. In the first, numeration is a protomathematic object, and its teaching is contained in that of numbers. The pupil first learns mechanisms and then their meaning through various exercises. In the second, numeration is a mathematical object, subject of explicitly designated teaching. We note the loss of the meaning and context of knowledge. We propose a new transposition in which the relations between numeration and numbers are dialectical. In the new didactic situations, numeration serves to give meaning to numbers and to build new ones. The pupil constructs a system of representation of the numbers which he modifies, improves or rejects by the play of certain didactic variables.

**Thesis title:**Conceptions des élèves et des professeurs a propos de la notion de continuité d'une fonction [Pupils' and teachers' conceptions concerning the notion of continuity of a function].

**University:**Université Laval (Québec, Canada).

**Advisors:**Claude Gaulin & Guy Brousseau.

**Note:**Abstract of the thesis. This research aims to study the conceptions expressed by Moroccan students and teachers at the end of secondary school about the notion of (simple) continuity of a function. In order to better achieve our objectives, we initially analysed the evolution of conceptions in the genesis of this notion, as well as the conceptions that have been conveyed by textbooks in Morocco since 1945. For the study of students' conceptions we used three means: the administration of a questionnaire to 311 students in 10 classes at the end of secondary school in Morocco; the organization of debates in each class on the answers to the questionnaire; conducting individual interviews with five students in each class. To study the conceptions of teachers and those they convey in teaching, we interviewed at length 20 teachers, including ten in charge of the ten previous experimental classes.**Soad Zaki MELEK [Egypt].****Year:**1982.

**Note:**Name on thesis is given as 'Antoinette Irène Rasolofoniaina'. Abstract of thesis. The study presented here focuses on factors that facilitate learning through reading. Different modalities of presentation of a text introducing the (congruence modulo m) were proposed to 1st grade students. After the reading, we asked the student to write down what they had retained from what had been read and we included a set of exercises to test the student's ability to apply what he had learned in the reading to solve problems. The main result observed was that the information best assimilated by the reader is that which satisfies both the following conditions: (i) It has been explicitly presented; (ii) it has been reused.**Heiltjie Magdalena RAUTENBACH [South Africa].****Year:**1983.

The maximum likelihood estimation procedure in the quaternion case is examined and the conclusion is reached that the estimation procedure is simplified if the unknown parameters of the associated real probability density function are estimated. The quaternion estimator is then obtained by regarding these estimators as the components of the quaternion estimator. By means of a example attention is given to a test criterion which can be used in the quaternion model.**Barbara SWART [South Africa].****Year:**1983.

**Thesis title:**Contribution à la modélisation par éléments finis des écoulements turbulents; application au remplissage en fonderie.

**University:**Ecole Nationale Supérieure des Mines de Paris (France).

**Advisor:**Michel Bellet.

**Note:**Abstract of thesis: This work deals with the numerical simulation of die-casting mold filing. It focuses mainly on turbulence modelling for non-stationary fluid flows. After a review of the various models described in the literature, our study deals with the simple zero-equation model and the more complex two-equation model of the k-e kind. After recalling the finite element methods used for solving laminar fluid flows (Chapter III), we describe in chapter IV the way the various models are taken into account in these methods. Two different formulations have been used, their results being quite similar: P2P0 elements with incompressibility penalization, and P2-P1 element using a mixed velocity-pressure formulation along with an Uzawa-like algorithm. With regard to (k, k / e) it was investigated with unsatisfactory results because it is far from the reference model k-e (Chapter V). A more efficient strategy has been the use of a modified Runge-Kutta time-integration scheme, which eliminates out-of-range (negative) values for the turbulence variables. Two cases of application of this model to the filling of molds (Chapter VI) have shown its capacity to account for the phenomena characteristic of unsteady turbulent flows with free surface.

**Thesis title:**Proprietés géométriques d'agregats de polygones aléatoires et application à la classification d'images.

**University:**Université de Montréal (Canada).

**Advisor:**Marc Moore.

**Note:**Abstract of thesis: "The first goal of this thesis is to establish new results about some random sets extracted from the Poisson and Voronoi tessellations of the plane. In addition to a random polygon we consider its neighbours and some aggregates of polygons. In particular, we introduce the concept of an amalgam generated by a polygon, that is the union of a polygon and all its neighbours. For each random polygonal set considered we study the number of sides, the perimeter and the area. We present all the algorithms to simulate the random sets considered and to compute their characteristics. The simulation study involve the generation of two millions independent realisations of each tessellations in a bounded region of the plane. Results are presented in the form of estimates (with standard deviations) and estimated distributions. Two indices are used to appreciate the degree of convexity of an amalgam; they involve respectively the perimeter and the area. For the Poisson tessellation it is shown that the convexity of an amalgam is related to the number of sides of the generating polygon. The second objective of this thesis is related to image analysis. We explore some properties of binary random mosaics obtained from the two processes considered in the first part. We introduce the concept of a patch in such an image. Algorithms to generate the portion of such a patch that is observable in a bounded region of the plane are constructed. It is also shown how some geometrical characteristics of this random set and its convex hull can be computed. A simulation study involving 4000 independent realisations of each of the Poisson and Voronoi images is reported. The empirical distribution of each of the two convexity indices mentioned above are presented. The one based on the area seems to depend only slightly on the intensity of the image generating process. We conclude by showing how this index could be used to discriminate between Poisson and Voronoi images."

**Thesis title:**Aspects of estimation in the linear model with special reference to collinearity.

**University:**University of Cape Town (South Africa).

**Advisors:**Tim Dunne and Cas Troskie.

**Note:**She has a Biometry degree from the University of Stellenbosch and a masters and PhD in Statistical Sciences from the University of Cape Town. Master's Degree thesis was*Collinearity and consequences for estimation: a study and simulation*(1990). Thesis Abstract begins, "Violations in the assumptions of the linear regression model lead to problems that make the ordinary least square estimator inappropriate. When the error terms are non-normal, the inference procedure that usually follows ordinary least squares estimation is no longer strictly valid. Collinearity, error terms that are non-normal and outliers are usually factors present to some degree in combination in a regression data set. Their effects may be confounded. In examining the factors separately the whole story is not told. We therefore set up a factorial design to investigate these problems under various scenarios." She held various positions in the Western Cape from biometrician in the Department of Agriculture, to computer science teacher and lecturer in mathematical and statistical sciences. She joined the Department of Statistical Sciences, University of Cape town in 1999 as a senior lecturer, and become an Associated Professor in 2004.

**Note:**She worked at the University of the Witwatersrand where she has advised at least four doctoral students. She published the book*Teaching mathematics in multilingual classrooms*in 2002. David Pimm writes in a Foreword: "In this book, Jill Adler has written an extensive account of her work exploring key dilemmas of secondary mathematics teachers' practice as they teach. She speaks with a strong 'I' voice, grounded in her practice as a researcher and much more, while at the same time lowering the ladder on the activity of research itself by careful and thoughtful commentary, with both her argument and rationale intentionally and explicitly presented. Adler focuses on three main dilemmas of multilingual mathematics teaching and learning and comments that "Teachers manage their dilemmas", adding also that "Every day, teachers in South Africa (and in many other countries), manage their mathematics teaching in multilingual settings." Adler writes: "First and foremost is my deep gratitude and respect for the mathematics teachers who are so central to this book. They welcomed me into their classrooms, gave generously of their time and participated in the research process openly, self-critically and with enthusiasm. I can only hope they benefited and were enriched by a process that undoubtedly enriched me. This book is the culmination of many years' work. As such, it has been shaped and influenced by many colleagues in the field as well as students in my graduate classes. I thank them all."**Deborah Olayide A.

Ph.D. thesis Abstract: "A model is considered for the dynamics of a size-structured population in which the birth, death and growth rates of an individual of size s are functions of the total population biomass of all individuals of size larger or smaller than s. The dynamics of the size distribution is governed by the McKendrick equations. An existence/uniqueness theorem for this equation is proved using an equivalent pair of partial and ordinary differential equations. The asymptotic dynamics of the density function is studied and some applications of the model to intraspecific predation and certain types of intraspecific competitions are given."
