    DEVELOPMENTS IN THE FIELD OF MATHEMATICS AND MATHEMATICS EDUCATION IN TURKEY DURING THE PERIOD OF 1938-1980 Prof. Dr. Ali BOZKURT Gaziantep University Assist. Prof. Dr. Emrah Berkant PATOGLU** Gaziantep University Introduction When the Republic of Turkey was founded there was a drive to keep up with contemporary civilization and an ambition even to go beyond. Mustafa Kemal Ataturk tried to pave the way for the modernization based on reason and wisdom by pointing out the fact that a civilization without science cannot be modern. As in all areas, these efforts are seen in the areas of science and technology. In the newly founded Republic, basic principles relating to science and technology are more often taught in educational institutions. Hence, developing education in scientific areas in an institutional manner and educating scientists have become a necessity. As in other scientific areas, it has been aimed to achieve advancements in the field of mathematics. In fact in the later times of Ottoman Empire era, the modernization of education began with opening institutions that were mainly using mathematics. In order to see the whole picture regarding the advancements in the field of mathematics, it is necessary to focus on the produced works of mathematicians along with the developments of the mathematics teacher education as well as changes introduced into mathematics curricula documents. In this study, therefore, we consider the developments in each of these topics during the years of 1938-1980. Developments in Mathematics regarding Undergraduate and Graduate degrees and Academic Studies Some institutions, subjected to radical reforms, have become scientific research centers with their new names and functions.

  • Apollonius of Pergaconics. Books One - Seven
    APOLLONIUS OF PERGACONICS. BOOKS ONE - SEVEN INTRODUCTION A. Apollonius at Perga Apollonius was born at Perga (Περγα) on the Southern coast of Asia Mi- nor, near the modern Turkish city of Bursa. Little is known about his life before he arrived in Alexandria, where he studied. Certain information about Apollonius’ life in Asia Minor can be obtained from his preface to Book 2 of Conics. The name “Apollonius”(Apollonius) means “devoted to Apollo”, similarly to “Artemius” or “Demetrius” meaning “devoted to Artemis or Demeter”. In the mentioned preface Apollonius writes to Eudemus of Pergamum that he sends him one of the books of Conics via his son also named Apollonius. The coincidence shows that this name was traditional in the family, and in all prob- ability Apollonius’ ancestors were priests of Apollo. Asia Minor during many centuries was for Indo-European tribes a bridge to Europe from their pre-fatherland south of the Caspian Sea. The Indo-European nation living in Asia Minor in 2nd and the beginning of the 1st millennia B.C. was usually called Hittites. Hittites are mentioned in the Bible and in Egyptian papyri. A military leader serving under the Biblical king David was the Hittite Uriah. His wife Bath- sheba, after his death, became the wife of king David and the mother of king Solomon. Hittites had a cuneiform writing analogous to the Babylonian one and hi- eroglyphs analogous to Egyptian ones. The Czech historian Bedrich Hrozny (1879-1952) who has deciphered Hittite cuneiform writing had established that the Hittite language belonged to the Western group of Indo-European languages [Hro].

In recent years, space-time coding is proposed to provide significant capacity gains over the traditional communication systems in fading wireless channels. Space-time codes are obtained by combining channel coding, modulation, transmit diversity, and optional receive diversity in order to provide diversity at the receiver and coding gain without sacrificing the bandwidth. In this paper, we consider the problem of blind estimation of space-time coded signals along with the channel parameters. Both con- ditional and unconditional maximum likelihood approaches are developed and iterative solutions are proposed. The conditional maximum likelihood algorithm is based on iterative least squares with projection whereas the unconditional maximum likeli- hood approach is developed by means of finite state Markov process modelling. The performance analysis issues of the proposed methods are studied. Finally, some simulation results are presented. Keywords and phrases: blind channel estimation, conditional and unconditional maximum likelihood. 1.

  • Or, Rethinking New German Literature – in Turkish?
    David Gramling University of Arizona Department of German Studies The Caravanserai Turns Twenty: Or, Rethinking New German Literature – in Turkish? ABSTRACT The Caravanserai Turns Twenty: Or, Rethinking New German Literature – in Turkish? This article aims to rethink the development of Turkish-German literature since the 1970s, with a special focus on the structural tension between monolingual and multicultural genres and social spaces. The boom of multicultural promotional politics in the FRG (1985-1995) initiated the ‚progressive monolingualization‘ of (publishable) literary utterances, a development that is reinforced today in German-only language policies at the federal and local level, as well as by the panethnic rubric of ‚Deutschsprachige Literatur‘ (German-language literature). Meanwhile, scholarship still lacks a critical narrative about contemporary translingual literature on German territory, one that would account for persistent literary historical and institutional-pragmatic lacunae within intercultural German Studies and intercultural publishing. Like an oblong piece of furniture being carried up a narrow staircase, Emine Sevgi Özdamar’s first novel bears one of the longest titles in twentieth century German literary history – if we agree to disregard Fassbinder’s 1974 film adaptation of Effie Briest.1 The author herself admits a preference for the complete, official title Life is a Caravanserai Has Two Doors I Came in One I Went out The Other, and though the significance of its length rarely garners critical attention, we might wonder: what was the German literary world to make of this roomy title, a lyrical text in itself, which flouts the Gricean maxims of quantity and manner? – already before the text as such comes on the scene (Grice 1975).
