Large N Phase Transitions and Multi-Critical Behaviour in Generalized 2D QCD

Using matrix model techniques we investigate the large N limit of generalized 2D Yang-Mills theory. The model has a very rich phase structure. It exhibits multi-critical behavior and reveals a third order phase transitions at all genera besides {\it torus}. This is to be contrasted with ordinary 2D Yang-Mills which, at large N, exhibits phase transition only for spherical topology.Comment: CERN-TH.7390/94 and TAUP-2191-94, 6pp, LaTe

The Kazakov-Migdal Model as a High Temperature Lattice Gauge Theory

We show that the Kazakov-Migdal (K-M) induced gauge model in $d$ dimensions describes the high temperature limit of ordinary lattice gauge theories in $d+1$ dimensions. The matter fields are related to the Polyakov loops, while the spatial gauge variables become the gauge fields of the K-M model. This interpretation of the K-M model is in agreement with some recent results in high temperature lattice QCD.Comment: 12 pages, plain latex, DFTT 71/9

Current control in the competence approach

This paper proposes a method of monitoring the knowledge-based test technologies and allows monitoring of formation of partial competencies. The proposed method is illustrated by the example of the course of computer scienceВ работе предлагается методика текущего контроля знаний, основанная на тестовых технологиях и позволяющая осуществлять частичный мониторинг сформированности компетенций.

Study of the results of use on the academic performance of the first-year students of applied mathematics and computer science

The paper discusses the influence of such factors as the results of the Unified State Examination on the academic performance of the first-year students throughout the school year. It uses the technique of grouping students according to their level of performanceВ работе рассматривается вопрос о влиянии такого фактора как результаты единого государственного экзамена на успеваемость студентов-первокурсников в течение всего учебного года. При этом используется методика группировки студентов по уровню их успеваемост
