Modelling Rupture of CO2 Pipelines

Department of Chemical Engineering

Reducing carbon dioxide emissions is considered to be the most effective
way of tackling the effects of global warming. This will require the
large-scale capture, transportation and storage of CO2. In the case of
coal fired power generation plants, pressurised pipelines are considered
to be the most practical, and possibly the only option for transporting
the captured CO2 for subsequent storage.

Given the enormous amounts of CO2 contained in such pipelines (typically
several million tonnes), a prior knowledge of the release rate and
subsequent dispersion in the event of pipeline rupture is central to
assessing the failure impact. CO2 is toxic and when inhaled in large
concentrations can lead to asphyxiation.

This exciting PhD project aims to extend our award winning work
(http://www.ucl. ac.uk/chemeng/ staff/mahgerefte h) to develop a computer
based model for predicting the failure consequences of CO2 pipelines.
The project carried out in close collaboration with a major industrial
partner is multidisciplinary involving a variety of subjects including,
fluid mechanics, mathematics, heat transfer, quantitative risk
assessment and computing. The experience gained is expected to equip the
prospective PhD graduate with job opportunities in a variety of
industrial sectors particularly in the oil and gas industry.

The successful candidate will be an outstanding First Class Chemical
Engineering or Mathematics graduate (although other relevant disciplines
will be considered) preferably with computing skills. The funding covers
full tuition fees plus maintenance over three years and is open to
suitably qualified overseas students.

UCL is consistently classed amongst the top Universities in the world.
The UCL Chemical Engineering department in particular received the
highest research rating in the most recent Government funded Research
Assessment Exercise placing it amongst the only three such departments
in the UK.

Linux Step By Step

Dual Booting, Windows XP and Linux Ubuntu Desktop

I still need my windows.

That my friend statement when he decide to give linux a try in his laptop after he feel comfortable with linux live CD.

Yes, in this post I’ll show how dual booting looks like and step by step effort to make computer with single windows xp into dual booting with linux OS.

1. Burn linux cd, in this case I use Ubuntu desktop 8.04

2. Reboot computer and make sure CD-ROM boot in first priority.

3. Make partition first for new operating system. (optional)

4. Installation started, some screenshots :

Could not determine the server’s fully qualified domain name

Thats message appear when I try to start apache using apachectl.

#apachectl start
[Thu Jun  5 16:31:33 2008] [alert] httpd: Could not determine the
server’s fully qualified domain name
, using 127.0.0.1 for ServerName
/usr/local/sbin/apachectl start: httpd could not be started

to solve this problem I need to know hostname and edit /etc/hosts to put that information (fully qualified name).

1. Find hostname

proxysudirman# uname -a

2. Edit /etc/hosts entry

proxysudirman# ee /etc/hosts

::1                     localhost localhost.my.domain
127.0.0.1               localhost localhost.my.domain

127.0.0.1               proxy proxysudirman.rasyid.net

172.88.1.2              proxy2 proxysudirman2.rasyid.net

3. Start apache service

proxysudirman# apachectl start
/usr/local/sbin/apachectl start: httpd started

Done icon smile Could not determine the servers fully qualified domain name

Partition Magic alike : Gparted

How dual booting looks like?

+ It show 2 options, windows and other OS

I don’t have partition magic, do you have recommendation?

+ Use parted, partition magic alike interface

I have Windows XP with space 8 GB, I’ll shrink the partition to 4 GB, the rest for Linux preparation. How to do that?

Here the steps :

1. Burn gparted iso into CD.

2. Boot your computer

3. Gparted ready to use :

parted Partition Magic alike : Gparted

Linux for Windows User

Is that hard to install linux?

I don’t wanna loose my windows, can I try linux in save way?

I wanna learn linux, have idea where I must start?

Well, I’ll start with this option :

1. Live CD, using live CD what you need just make sure you choose to boot from CD-ROM or DVD-ROM. Few linux distribution that provide Live CD version for end user to ‘taste’ :

2. With Linux Embed, run linux inside windows

3. Virtualization, install linux as guest OS , a few software that support that option are :

Vmware provide many ‘pre install OS’ ready to use, just browse at their appliance center. Many OS variant ready to serve with one note : Huge Memory inside your PC or notebook.

whats wrong with above config?

Yes, auto keyword.

Thats today lesson that I’ve learn after get confuse when my staff add new public address into eth1.

the right config after ‘little’ mess making by delete auto ethx to wrong location is easy.

Just adding ‘auto lo‘ for loopback.

auto eth0, for lan connection.

auto eth1, for public connection

restart connection  and voila!

It work like a charm icon smile auto and eth
