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

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

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

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

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

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

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.
