Finite element simulation of 3D drilling in unidirectional CFRP composite
Drilling is probably the most important conventional mechanical process and it is the most widely used machining operations. Prediction of cutting forces for any set of cutting parameters is essential in optimal design and manufacturing of products. It has been predicted that most of the problems associated with hole making operation, such as drilling, can be attributed to the force generated during cutting operation. In addition, prediction of force helps in design and evaluation of cutting too
Developing Future Leaders
If Woodie Flowers gets his way, students with the vision and initiative to change the world will be commonplace at MIT – rather than the extraordinary exemplars who speak on his panel: Elizabeth Basha, who’s developing an early storm warning system for rural villages in a Honduras river basin prone to
The War in Afghanistan: How to End It
[from the MIT News Office]
British Foreign Secretary David Miliband urges the Afghanistan government to consider bringing Taliban supporters into its political system, telling an MIT audience that the prompt pursuit of a political deal among Afghanistan’s warring factions is necessary to build a lasting p
4.6 Consequences of neural ageing
This unit looks at two topics that are of immense worldwide social, economic, ethical, and political importance – ‘addiction’ and ‘neural ageing’. You will develop a Master's level approach to the study of specific issues within these two important subject areas.
MUSC Weight Management Center- Lunchtime Losers Program
Lunchtime Losers is a 10-week program offered at the Medical University of South Carolina Weight Management Center. It is designed with convenience in mind, because you can come to class-based meetings during your lunch hour.

Monetary policy & the financial crisis
Professor Chris Martin investigates the country's current financial crisis looking at the underlying cause, the symptoms and long-term effects.
4.2 Definitions of ageing
This unit looks at two topics that are of immense worldwide social, economic, ethical, and political importance – ‘addiction’ and ‘neural ageing’. You will develop a Master's level approach to the study of specific issues within these two important subject areas.
1 What is accounting about? Let's start with a question – we shall call questions ‘Activities’. For many of these activities you will need a pen and paper, or you can use the unit Forum, to note down your own ideas. Once you have completed the Activity you should return to the text, read the comments that follow the activity, and then think again about your answer. Change it, if you like. Once you are happy that you have understood the comments and that your own answer is alright, you should continue to read

Introducing interactive whiteboards in the schools: an experience report
We report the findings of a project aimed at introducing Interactive Whiteboards in schools (both primary and secondary). We focussed on the early phases (installation, introduction, training, first use). We find that there are indeed problems that need to be tackled before one can hope to obtain the good results that are promised by the marketing hype.
Pour une meilleure intégration de l’utilisateur dans le processus de conception et d’évaluation
Le système TELOS intègre un ensemble dÂ’architectures, de méthodes et dÂ’outils appelés à transformer en profondeur le fonctionnement institutionnel et les pratiques professionnelles en matière de conception, de production et de diffusion de cours et dÂ’apprentissage en ligne. TELOS suppose non seulement lÂ’appropriation de nouveaux outils technologiques, mais aussi un nouveau modèle de travail qui prend appui sur une ingénierie pédagogique rigoureuse et sur lÂ’accès à des banques dÂ
Supporting Social Interaction in an Intelligent Collaborative Learning System
Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge. The benefits of collaborative learning, however, are only achieved by active, well-functioning teams. This paper presents a model of collaborative learning designed to help an intelligent collaborative learning system identify and target group interaction problem areas. The model describes potential indicato
Data Driven User Requirements Specification in the UNITE Project
This paper describes the process of user requirements specification in UNITE
project. The main goal of the project is to develop an integrated system for
authoring and delivery of high quality eLearning activities for the secondary
school students. The UNITE system consists of three main components: 1)
Software Platform – integrating state of the art learning management systems
(LMS), content management systems (CMS), and mobile learning (mLearning)
capabilities; 2) Pedagogical Framework – s
Harnessing Technology: Transforming Learning and Children's Services
This document is the Department for Education and Skill's first cross-sector e-learning strategy. The strategy focuses on what the technology can do for informing and advising citizens, for supporting children and learners of all ages in their encounters with the system, and for transforming the experience of learning. To make this happen, it identifieds six priorities, to provide:
• An integrated online information service for all citizens
• Integrated online personal support for children
A modelling challenge : untangling learner knowledge
For now about three decades, systematic research on students learning of science and mathematics has evidenced a great variety of the possible understanding for a given notion, as well as an important sensitivity of these understandings to contexts. Students' knowing appears as a tangle of local conceptions of which we have a very partial and unorganised picture. We present here the outlines of the modelling tool we have developed, and of its framework, in order to give account of learners' know

4.2 Analysing the task
Learning how to learn: a process we all engage in throughout our lives, but no single method of learning guarantees success. This unit aims to make the process of learning much more explicit by inviting you to apply various ideas and activities to your own study as a way of increasing your awareness of your own learning. Most learning has to be an active process – and this is particularly true of learning how to learn.
5.2 Viscoelasticity of polymers The simplest models for the deformation behaviour of an ideal material are those of Hookean linear elasticity in the solid state, and Newtonian linear viscosity in the liquid state. The end point of elastic deformation is either fracture or plastic flow, with the latter taking place at a constant yield stress in the ideal case. Whilst the behaviour of many real materials does approximate to these idealised models, that of polymers deviates markedly from them. In particular, their solid state
