Mat-1.174 Bulletin board 1999

Notices will be written on "FIFO" basis ("First in first out") (In "Finnish": Most recent on top)

Final seminar Fri 14.5, 8-12
Last "official" exercise Thu 29.4.

3.5.
Some new instructions about boundaries

Some additions to project suggestions(27.4.)

You can work in groups of two people or individually. The ideal duration for presentations is 20 - 30 min.

22.4.
Quite detailed outline of how to write an elegant piece of Matlab code to find the stiffness matrix

Exercise session this week on Thu 22.4.

20.4.
Getting started with project work
Tools and ideas
Tools directory
8.4.
PDE toolbox-problem: Name u is reserved in the toolbox, there was u.m in the Cooper-codes that caused problems. Now it has been changed into uuu.m. (Perhaps it's good to do >> type u before using pdetool.) If some of the Cooper codes don't work, this is an explanation.
31.3.
The next session will be Thu 8.4. Please check the pages harj5.html and hints5.html . Some more will be added to this set before the next session. Try to get at least started with these, we will continue working on "harj5" on Thursday.

PDE toolbox vs. Femlab

It seems there are difficulties in installing Femlab to the alphas. So we will work with pdetool in classroom. There's at least one group (Veera and Mikko) who installed Femlab into their PC's and will do their final project work with it. This is an option for other's, too.

PDE toolbox manuals

There are 3 manuals that can be borrowed in Riikka's office. In addition some manuals should be found in the math library.

18.3. Solutions for "harj. 3" . Please hand in by Tue 23.3 (at the lecture or to Riikka (even her "doorenvelope")). Of course the computer work should be placed into the course directory or at some suitable URL. Typical pen/paper portions can be handed in as such, no need to text-process everything.

We encourage you to make an effort to get "Harj 4" done by Fri 26.3.
18.3.
See Literature and software page for some additions. Especially there is a text file ohjelmat.mpl" that you can read into a Maple session by >read("ohjelmat.mpl");
18.2.
PDE toolbox links added on this page
Some further ideas (Matlab tools)
15.2.
Skii'ing holiday will be held on week 8 as some students have planned so anyway. It will just shift the Spring term 1 week ahead, which is not bad (we think).

Presentations on Tue 16.2

Nr. 2 (Method of characteristics) Janne Viljas
Nr. 4 (Wave equ) Mikko Hämäläinen & Veera Rantasalo
Nr. 5 (Heat/diffusion) Badal Durbo

Presentations on Thu 18.2

Nr. 4 (Wave equ, difference method) Laura Astola
Nr. 3 Jaana Kanervo
Nr. 3 Mikko Kokkonen

Presentations on Tue 2.3/Fri 5.3.

Nr. 2 (More on Method of Characteristics) Lauri Markelin
Nr. 3 Tellervo Brandt (Also Non-linear conservation laws, schock waves, etc., we allow ample time spent on this.)
Nr. 5 (Heat/diffusion) Reija Ristilä
Nr. 5 (An example on Heat equ, special geometry) Gibson&Gosalvez (Fri)

3.2.
Solutions extended (dir field for autonomous).
Cooper-, Betounes- and Belzer-codes made visible, right here

2.2.
The up-to-date Maple worksheet is now available at the proper link and even here. Also at /p/edu/mat-1.174/maple/lap-sep.mws

There's a link to the list of participants just below. The project groups are indicated there. Please check.

Exercise session on Fri 12-14 on the weeks nr. 6,8,9,10,12,15,17,19. Thursday seems to be non-suitable for quite a few participants. We suggest that we have exercise session on Fri 12-14 on the weeks nr. 6,8,9,10,12,15,17,19. (Those are the weeks when the classroom was available.) For the rest we keep Thu 14-16 as before. Also Thu 14-16 will be reserved for us, perhaps it is good to have a time reserved when some of you can work together I (Heikki) can be there at least for some time each Thursday at least to authorize our participants the priority to work there and also for some questions. These reservations have been made, let's discuss this on Tue, you can also send your opinion on this by mail to Riikka.

There were some nice presentations today. Not all had had the time to finnish their work, though. Please make an effort to get as much as possible done by Tuesday 2.2. (It is not forbidden to peek at the solution pages.) At the very least you should get a good understanding of the solutions and make some personal comments on the files and pages you write and make available.

On Tue 2.2. we will go through the solution to probl. 5 and make some comments of solutions to other problems as well. Especially if there's something you would like to be explained, please let us know. We will also start project work, so no (or little) actual "lecturing" on Tue. 26.1.

There are some new instructions, actually here .
On Thu 28.1. we will look at your solutions. (It is fun to use the video "gun".) We will look at the solution quite carefully and give ours (perhaps a few alternatives) in the end. It is possible thet we will have to postpone the handling of perhaps the last problem until next Tuesday. The idea is to get everybody into the level of enjoying the work, not to push too hard.
I mentioned project work to be done next. We will give suggestions of small project work on Tue 2.2.

18.1.
Welcome to the course! We ask you to send a message to Riikka.Nurmiainen@hut.fi Include in your message:

- e-mail, tel-nr. student-id, "osasto/koulutusohjelma", www-home-page
- Background: Math. in general, especially ODE, PDE, numerical methods, etc.
              Computing: Matlab, Maple, Mathematica, other
- Interests, related projects of your own (suitable for final work)
- What would you most desperately/willinly like to learn
- Other comments

We will collect all info into a file to make available to everybody in the course. Please indicate if there's any personal info that you don't want to share. (Perhaps it is more practical to put item 1 only on the general list.)
