Chamilo to bezplatny, bezpieczny, latwy w użyciu system ksztalcenia na odleglośc, kt ry można latwo pobrac i skonfigurowac i kt ry może byc wykorzystywany w każdej instytucji oferującej kursy na odleglośc. System można skonfigurowac w r żnych językach i zgodnie z potrzebami każdej instytucji. W związku z tym celem bylo przejrzenie bibliografii i dostosowanie AVA Chamilo do potrzeb Federalnego Instytutu Edukacji i Technologii w Tocantins (IFTO), tak aby dostosowac go do jego potrzeb i zapewnic użytkownikom ksztalcenia na odleglośc alternatywny system o dobrej użyteczności. Dostosowanie obejmowalo zmiany związane z wymianą logo, kolorami platformy, dodaniem film w, link w i wiadomości oraz ograniczeniem liczby język w do portugalskiego, angielskiego i hiszpańskiego. Utworzono r wnież rejestry użytkownik w o r żnych profilach, kategorie kurs w, kursy i oceny. Po dostosowaniu przeprowadzono badania terenowe z wykorzystaniem kwestionariuszy, aby poznac platformy AVA i opinie ludzi na temat ksztalcenia na odleglośc, a także przeprowadzono testy w celu sprawdzenia użyteczności Chamilo. Po dostosowaniu Chamilo zostalo ocenione jako latwe w użyciu.

Anpassung des Fernunterrichtssystems Chamilo

Anpassung des Fernunterrichtssystems Chamilo

Celina Ferreira Ribeiro; Francisco W. M. Hirano; Marcelo Moreno Costa

Verlag Unser Wissen
2025
nidottu
Chamilo ist ein kostenloses, sicheres, benutzerfreundliches Fernunterrichtssystem, das einfach herunterzuladen und zu konfigurieren ist und in jeder Einrichtung, die Fernkurse anbietet, eingesetzt werden kann. Das System kann in verschiedenen Sprachen und entsprechend den Anforderungen jeder Einrichtung konfiguriert werden. Vor diesem Hintergrund wurde eine berpr fung der Literatur und eine Anpassung des AVA Chamilo an das Bundesinstitut f r Bildung und Technologie von Tocantins (IFTO) angestrebt, um es an dessen Anforderungen anzupassen und den Nutzern des Fernunterrichts ein alternatives System mit guter Benutzerfreundlichkeit zu bieten. Die Anpassung umfasste nderungen wie den Austausch des Logos, die Farben der Plattform, das Einf gen von Videos, Links und Nachrichten sowie die Reduzierung der Sprachen auf Portugiesisch, Englisch und Spanisch. Au erdem wurden Benutzerprofile mit unterschiedlichen Profilen, Kurskategorien, Kursen und Bewertungen erstellt. Nach der Anpassung wurde eine Feldstudie mit Frageb gen durchgef hrt, um die AVAs und die Meinung der Menschen zum Fernunterricht kennenzulernen, und es wurden Tests durchgef hrt, um die Benutzerfreundlichkeit von Chamilo zu berpr fen. Das angepasste Chamilo wurde als benutzerfreundlich bewertet.

Customization of the Chamilo Distance Learning System

Customization of the Chamilo Distance Learning System

Our Knowledge Publishing

Chamilo is a free, secure, easy-to-use distance learning system that is simple to download and configure and can be used in any institution that offers distance learning courses. The system can be configured in several languages and according to the needs of each institution. Given this, the objective was to review the bibliography and customize the Chamilo VLE to suit the Federal Institute of Education and Technology of Tocantins (IFTO), in order to adapt it to its needs and provide users of distance learning with an alternative system that has good usability. The customization included changes involving the replacement of the logo; platform colors; insertion of videos, links, and news; and reduction of languages, leaving only Portuguese, English, and Spanish. User registrations with different profiles, course categories, courses, and assessments were also created. After customization, field research was conducted with questionnaires to learn about AVAs and people's opinions regarding distance learning, and tests were carried out to test the usability of Chamilo. After customization, Chamilo was evaluated as having good usability.

The European Union after Amsterdam

The European Union after Amsterdam

Niels M. Blokker; Ton Heukels; Marcel M.T.A. Brus

Kluwer Law International
1998
sidottu
This book reflects the proceedings of the conference on the Institutional and Constitutional Dimensions of European Integration, asking the question - will the European union meet the challenges of the 21st-century? The conference was held on 6 and 7 November 1997 on the occasion of the 40th anniversary of the Europa Institute of Leiden University. The congress has resulted in a collection of contributions. Together they not only reflect the significance, the positive outcome, the deceptions and the unfulfilled expectations of the Treaty of Amsterdam, but they also constitute a stocktaking of the European Union as a whole. The contributions of the seventeen authors in this volume differ in their approach to the current State of the Union. Some contributions are highly political in nature, as one might expect from a former President of the European Parliament (P. Dankert) or from a former Deputy Prime Minister of the United Kingdom (Lord Howe).

Analog-to-Digital Conversion

Analog-to-Digital Conversion

Marcel J.M. Pelgrom

Springer Nature Switzerland AG
2022
sidottu
This textbook is appropriate for use in graduate-level curricula in analog-to-digital conversion, as well as for practicing engineers in need of a state-of-the-art reference on data converters. It discusses various analog-to-digital conversion principles, including sampling, quantization, reference generation, Nyquist architectures and sigma-delta modulation. This book presents an overview of the state-of-the-art in this field and focuses on issues of optimizing accuracy and speed, while reducing the power level. This new, fourth edition emphasizes novel calibration concepts, the specific requirements of systems, the consequences of advanced technology and the need for a more statistical approach to accuracy. Pedagogical enhancements to this edition include additional, new exercises, solved examples to introduce all key, new concepts and warnings, remarks and hints, from a practitioner's perspective, wherever appropriate. Considerable background information and practical tips, from designing a PCB, to lay-out aspects, to trade-offs on system level, complement the discussion of basic principles, making this book a valuable reference for the experienced engineer.

Springer International Publishing AG

This book proposes innovative circuit, architecture, and system solutions in deep-scaled CMOS and FinFET technologies, which address the challenges in maximizing the accuracy*speed/power of multi-GHz sample rate and bandwidth Analog-to-Digital Converters (ADC)s. A new holistic approach is introduced that first identifies the major error sources of a converter’ building blocks, and quantitatively analyzes their impact on the overall performance, establishing the fundamental circuit-imposed accuracy – speed – power limits. The analysis extends to the architecture level, by introducing a mathematical framework to estimate and compare the accuracy – speed – power limits of several ADC architectures and variants. To gain system-level insight, time-interleaving is covered in detail, and a framework is also introduced to compare key metrics of interleaver architectures quantitatively. The impact of technology is also considered by adding process effects from several deep-scaled CMOS technologies. The validity of the introduced analytical approach and the feasibility of the proposed concepts are demonstrated by four silicon prototype Integrated Circuits (IC)s, realized in ultra-deep-scaled CMOS and FinFET technologies.Introduces a new, holistic approach for the analysis and design of high-performance ADCs in deep-scaled CMOS technologies, from theoretical concepts to silicon bring-up and verification;Describes novel methods and techniques to push the accuracy – speed – power boundaries of multi-GHz ADCs, analyzing core and peripheral circuits’ trade-offs across the entire ADC chain;Supports the introduced analysis and design concepts by four state-of-the-art silicon prototype ICs, implemented in 28nm bulk CMOS and 16nm FinFET technologies;Provides a useful reference and a valuable tool for beginners as well as experienced ADC design engineers.
