Cavitation on Ship Propellers
Summary: Cavitation is the transition of a fluid into vapour due to local reduction of pressure which is generated by high local flow velocities. The transition of a fluid into vapour also occurs during cooking of water by an increase of the local temperature. The term cavitation is generally reserved for conditions in which the temperature of the bulk fluid is not changed. Although cavitation can occur in many situations this course focuses on ship hydrodynamics and ship propellers. The course
4.2 Circles Recall that a circle in 2 is the set of points (x, y) that lie at a fixed distance, called the radius, from a fixed point, called the centre of the circle. We can use the techniques of coordinate geometry to find the equation of a circle with a given centre and radiu

7.3 Depositing metals and alloys Metal layers are used extensively in device fabrication: to carry current for both power and signals, to apply the voltages that control transistors and generate forces for MEMS, as mirrors and optical coatings, and in magnetic devices for recording media. Different applications might require a continuous film, a long track, multiple thin layers or a plug filling a ‘via hole’ through to a buried layer. The electrical properties resulting from micro structure and composition must be contro

This reflective case study and poster relates to a specific event staged by students and examines the phases and critical points within the whole process. It identifies some key learning outcomes for all involved
Solving Inequalities in One Variable: Part 1 of 2
The instructor uses an electronic sketchpad to demonstrate how to solve linear inequalities in one variable. This video is part 1 of 2 and several problems are solved and plotted on a number line.
1.9 Summary and conclusion: ‘take-away messages’ It helps to understand the PhD in context: the modern PhD is typically a three-year research training providing evidence of the ability to conduct and bring to fruition an independent programme of research. It requires rigour and an ability to enter the discourse, but its scope is limited and it does not require perfection. Models of study and models of dissertations vary for different universities, disciplines, and topics. The key is to understand what is appropriate for your particular prog

CK-12 Life Science (CA Textbook)
CK-12’s Life Science delivers a full course of study in the life sciences for the high school student, relating an understanding of the history, disciplines, tools, and modern techniques of science to the exploration of living things, the building blocks of life, genetics and evolution, the kingdoms of life, the human body, and the ecology of living communities. This digital textbook was reviewed for its alignment with California content standards.

Workshop White Paper - Technology-enhanced learning in the context of technological, societal and cu
This paper reports on the aims, processes and outcomes of a workshop organised by Norbert Pachler (London Mobile Learning Group; www.londonmobilelearning.net) on technology-enhanced learning in the context of transformation as part of the STELLAR Alpine Rendez-Vous in 2009. The aim of workshop was to augment the work of the LMLG around its socio-cultural ecology, and to extend the interdisciplinary nature of its work through exposure to perspectives advanced by (TEL) researchers in cognate field
Conducting a Joint Course on Software Engineering Based on Teamwork of Students
For the previous six years, under the auspices of the ``Stability Pact of South-Eastern Europe'' and DAAD, a joint project for developing a course in ``Software Engineering'' has been conducted. The intention of the project was to enable usage of shared materials for software engineering courses at a wide range of universities in participating countries. During school-year 2004/05, for the first time the same course, with the same case study, and the same assignments has been conducted at the Hu

This study is a preliminary work before the development of the CoPEX software that helps students and teachers to design experimental procedure. To this date, there are no other intelligent learning environments for this task. An experiment was done in two high schools during an immunology course (a lecture and a practical work). It is done in ecological conditions during a laboratory session with students majoring in science (ISCED level 3A-16/18 years old). Students designed (imagined, wrote a
Using and Enhancing a Normalized IMS-LD Description to Support Learners in their Appropriation of a
The general context of our work is the support that can be proposed to a distance learning student in order to appropriate a curriculum to him. In this paper we explore how the IMS learning design (LD) norm can be used to address this issue. An LD model of a curriculum permits the construction of tools that allow a student to visualize different points of view on the curriculum items, annotate his progression in the activities or build individual projects. We present what can be done with an LD
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.
Online Library of Scientific Models - A New Way to Teach, Learn, and Share Learning Experience
While scientific models are usually communicated in paper format, the need to reprogram every model by every user results in a huge loss of efforts, time and money, hence lengthening the educational and research developing cycle and loosing the learning experience and expertise gained by every user. We demonstrate a new portal www.imodelit.com that hosts a library of scientific models for electrical engineers in the form of java applets. They are all conformal, informative, with strong input and
Digital astronomy in education
What causes seasons? Why day and night durations are so different with seasons alternation? Why the position of the full moon seems directed to the south in summer while it seems directed to the north in winter? It is the purpose of this computer simulation to provide an interactive application, programmed in Java language to explore the issues related to the above questions.
Exploitation of Croquet CVE Platform for supporting Collaborative e-Learning Environments
This paper reviews the features of five 3 dimensional networked virtual environments which support collaborative learning applications, through the comparison of the tools and services they offer. Following that, we justify our choice of platform, which is the Croquet platform, and discuss design and implementation issues. Finally we present the results of the evaluation process of the virtual environment we developed, which consisted of the participation of twelve postgraduate students who comp
Knowledge Management: As a Mechanism for Large-Scale Technological and Organizational
Organizational and Technological changes in Israeli universities are taking place without a clear and well-planned model for managing those changes. Universities must adapt to daunting social and educational challenges, in which technology is playing a bigger role than ever before. The model we propose is implementing knowledge management strategies for achieving change management at universities in order to facilitate university's transformation. By doing that, we are establishing a well planne
Changes in education: implications for teacher education.
This communication present the implication of the introducing of ICT in teacher training education, at the IUFM of Grenoble.
Implementing the Challenge Based Learning in Classroom Scenarios
Our Challenge Based Learning (CBL) method can be described as a special form of problem-based learning, in which the problems are of realistic, open-ended nature. Additionally, CBL contains features of experiential and project-based learning approaches. CBL is supported by the provision of Digital Experimentation Toolkits (DExTs) which comprise materials, initial instructions, references to web resources and specific software tools. Within the COLDEX project, a number of remote sites which gener
