Stations 4 and 5 of the ALICE Muon Spectrometer: Modular Approach

Abstract Here we present a modular approach for the tracking chambers TC7, TC8 (station 4) and TC9 , TC10 (station 5) of the ALICE Muon Spectrometer (notations from the ALICE Muon Spectrometer Technical Proposal [1]). The chambers are located between the dipole magnet and the iron wall of the muon shield. This approach renews our proposal formulated first in 1996 [2] and also takes into account the results of the beam tests of the one square metre SCSC (Segmented Cathode Strip Chamber) prototype designed and constructed at PNPI [3]. The general requirements and segmentation criteria are presented in Section 1. Some details of the chamber design are given in Section 2. Section 3 describes the technology of the chamber construction. The results of the ANSYS calculation of the cathode planes possible deformations are presented in Section 4. The primary consideration of the chariot design can be found in Section 5. </HTML

Author Conceptual Bases of the Manuals in Mathematics for 5th - 6th Forms

У статті розглянуто концептуальні засади створення підручників математики нового покоління для 5-6 класів. Проаналізовано змістове наповнення підручників з урахуванням науково-методичних вимог Державного стандарту. Розглянуто питання науковості і доступності викладу. Особливу увагу приділено пріоритету розвивальної функції навчання. Виокремлено етапи диференційованої реалізованості: формування стійкої мотивації до вивчення предмета та ключових і предметних математичних компетентностей. У статті виділено методологічні засади побудови сучасних підручників математики через реалізацію особистісно орієнтованого, компетентнісного, діяльнісного підходів до навчання математики. Комплект підручників сприяє вихованню в учнів уважності, спостережливості, зацікавленості, відповідальності, акуратності, точності, становленню позитивної Я-концепції, відчуванню ситуацій успіху тощо.Conceptual basics of compiling the manuals in mathematics of the new generation for 5th - 6th forms are considered in the article. A content filling of the manuals according to scientific and methodical requirements of the State standard is analyzed. The issues of simplicity and scientific nature of the presentation are considered. Special attention is given to the priority of training developmental function. The stages of differentiated realization are pointed out: formation of the firm motivation for studying the subject and key, as well as subject mathematical competences. Methodological bases of compiling up to date manuals in mathematics through realization of personally oriented, competence-based, activity-based approaches to mathematics studying are defined in the article. A set of manuals makes for cultivating pupils’ attention, observation, interest, responsibility, neatness, precision, positive self-concept formation, success sensing situations, etc

Event reconstruction of free-streaming data for the RICH detector in the CBM experiment

The Compressed Baryonic Matter (CBM) experiment is a dedicated heavy ion collision experiment at the FAIR facility. It will be one of the first HEP experiments which works in a triggerless mode: data received in the DAQ from the detectors will not be associated with events by a hardware trigger anymore. All raw data within a giventime period will be collected continuously in containers, so-called time-slices. The task of the reconstruction algorithms is to create events out of this raw data stream. In this contribution, the optimization of the reconstruction software in the RICH detector to the free-streaming data flow is presented. The implementation of ring reconstruction algorithms which use time measurements of the hits as an additional parameter is discussed
