## Details

#### 8th October 2015: Correction to introductory remarks in Part II project 17.1

The introductory remarks in italics have been amended, removing the previously-stated restriction to values of $$k$$ dividing $$n$$.

#### 27 August 2015: Minor clarifications to Part II Project 5.4

Project 5.4 has been edited to introduce a number of clarifications. These changes do not affect the mathematical or computational requirements.

#### 21st August 2015: Modification to Part IB Project 2.2

In the non-dimensionalisation following equation (4) a factor of 1/2 has been removed from the definition of $$\Phi$$, resulting in changes to equations (6) and (8) and consequent adjustments later. You will not be disadvantaged if your work is completed on the basis of the original project definitions.

#### 29th July 2015: Part IB Manual online

The Manual containing the Part IB Projects for 2015-16 is now available online. If perchance you note any misprints, we would be grateful if you could draw them to our attention.

However familiar you already are with computing, you will need to read the Introduction to the Manual before starting either on the Introductory Project 0.1 (for which a solution will be posted early in the Michaelmas Term), or on the Core Projects 1.1 and 1.2 (which are due to be submitted at the beginning of the Lent Term). Please note that

you are required to submit your project reports both as hard-copy and electronically. In particular you will be asked to submit your write-ups electronically in Portable Document Format (PDF) form. Please see the Introduction to the Manual for more details.

Please note that while there are no quality marks, i.e. alphas and betas, for CATAM, the maximum contribution to the final merit mark is roughly the same (averaging over the alpha weightings) as for a 16-lecture course.

Please also make sure you familiarise yourself with the section on Unfair Means, Plagiarism and Guidelines for Collaboration in the Introduction to the Manual.

#### 29th July 2015: Part II Manual online

The Manual containing the Part II Projects for 2015-16 is now available online. If perchance you note any misprints, we would be grateful if you could draw them to our attention.

However familiar you feel you already are with the Computational Projects course, you will need to read the Introduction to the Manual. You are required to submit your project reports both as hard-copy and electronically. In particular you will be asked to submit your write-ups electronically in Portable Document Format (PDF) form. Please see the Introduction to the Manual for more details.

As was the case last year, while there are no quality marks, i.e. alphas and betas, for CATAM, the maximum contribution to the final merit mark is the same as the maximum for a 16-lecture course.

Please also make sure you familiarise yourself with the section on Unfair Means, Plagiarism and Guidelines for Collaboration in the Introduction to the Manual.

#### 24th June 2015: Optional introductory CATAM project available

An optional introductory non-examinable CATAM project is available. Unlike the other projects there are no marks awarded for it and, also unlike other projects, you may collaborate and (if your College is willing) have a supervision on it. A model answer will be available a few weeks into Michaelmas term.

#### 27th March 2008: Warning - cached pages

When checking the latest online version of a project before finalising your write-up, ensure that your computer has not 'cached', and is therefore displaying, the previous version that you accessed.

#### 31st January 2007: Make sure you get through to the CATAM Helpline

When emailing the Helpline:

(1) Always write from your University email address (@hermes or @cam)

(2) If a project is involved, put it it the subject line: e.g., Part II Project 14.5. Otherwise make it clear how the email relates to CATAM, e.g. mention MATLAB.

(3) Include a clear message in the body of the email, making clear the relevance to CATAM: e.g. I have attached the electronic versions of my Part IB Core CATAM Projects.

(4) Only discuss one project and, ideally, only one question in each email.

If for good reason you cannot achieve (1), be particularly careful about (2) and (3).

At first sight the above may seen rather pedantic and unnecessary. However it is the cost of modern communications: the University estimates that it receives over 6 million messages per day of which at least 90% are spam. Most is filtered by the University's spam filter, which will remove emails with no message for example. What gets through to the Helpline still needs filtering, which is done ad hoc, mainly by reference to the sender's address and the subject line.

#### 22nd April 2004: File security

It is important that you keep backup copies of your project files on CD, memory stick or floppy disk to guard against loss by human error (accidental overwriting or deletion), or by hardware problems on your own computer or University/College fileservers.

Do not leave copies of your project files behind on the local hard disk of Managed Cluster Services (MCS) or College computers. If someone took a copy of your work and incorporated it in one of their own programs, you might be

accused of unfair collaboration by the Project Assessors.

If you lose a memory stick or floppy disk containing your programs, please report it to the CATAM helpline.

The Computing Service publish these notes on file security on the MCS.
