Today smart phones have revolutionized Engineering Computations. Computer Aided Engineering (CAE) is now more easy and accessible with help of android tablets and phones.
CalculiX CrunchiX Solver – ccx is one of the most powerful Multiphysics GNU Finite Element Solver. This post is about how to compile and run gnu ccx on android. The code tested on HTC Incredible S and Android version 2.3.3.
If you are familiar with ccx or you can execute abaqus inp files using ccx, then, this script is helpful to you. Following steps show how to compile and run ccx on android.
Nowadays web trend is for free decentralized web services. Instead of centralized video tubes, social network and cloud, web developers and users prefer decentralized and free(dom) web services. This post overviews free video hosting alternatives for web developers and bloggers. It is about encouragement to your own video service right on your website or blog and embedding the video links from websites other the youtube.
There are 04 solutions and you can choose the one which suits you:
HTML5 video tag.
VideoPress plugin for WordPress site.
Embedding links from websites other than youtube.
1. HTML5 Video Tag:
If you have a little know how of how html works then you can easily tag video in following steps.
Detailed steps are found at FLOSS Manual. The link of their website is given below in reference.
2. VideoPress plugin for WordPress site:
If you are running wordpress site which is either hosted in premium account or hosted by yourself, you can easily manage your uploaded video using videopress plugin. You can install VideoPress Plugin just like another plugin right from your WP dashboard. VideoPress Quick Start Guide is helpful resource.
mediagoblin.org is a free software media publishing platform that anyone can run. You can think of it as a decentralized alternative to Flickr, YouTube, SoundCloud, etc. It required dedicated web server.
4. Embedding links from websites other than youtube:
Following points are helpful to provide construction joint in RC Slab, Beam and Raft Foundation:
Construction joint shall be provided preferably at a location where stress are zero.
Construction joint is provided at one-third or end of support.
Also provide key and rebar to transfer shear stress if shear stress is not zero at point of construction joint.
Provide construction joints as minimum as possible.
Construction joint shall not be left on discretion of contractor. It must be approved by designer.
Construction joints are placed at the end of a day’s work. In slabs, they may be designed to permit movement and/or to transfer load. Often in reinforced concrete a conscious effort is made to clean the joint and bond the next day’s work..
The number of construction joints in concrete structures should be minimized. If construction joints are necessary to facilitate construction, it is normally aligned perpendicular to the direction of the member. For beams and slabs, construction joints are preferably located at about one-third of the span length. The choice of this location is based on the consideration of low bending moment anticipated with relatively low shear force. However, location of one-third span is not applicable to simply supported beams and slabs because this location is expected to have considerable shear forces and bending moment when subjected to design loads. Sometimes, engineers may tend to select the end supports as locations for construction joints just to simplify construction. .
Construction joint is not preferred at midspan. When formwork removed from construction pours (delay in next pouring) and the beam (or slab) has had to cantilever from the previous support to the new construction joint. Also, joints at midspan do not typically work for post-tensioned construction. you need to accommodate anchorages and at approx 1/3 span works best. .
You need to provide a joint with key and rebars crossing the joint. In raft footing, at construction joint, shear force may not be minimum/zero. Hence you will have to leave dowels from one pour to another pour to transfer shear. You may calculate area of reinforcement required based on permissible shear stress as 0.45 fy. .

As to date i.e., 30/09/12, qgis-plugin-grass was not installable because it required a package grass641 which is not available in any repo (stable, testing, unstable, experimental) of debian. I have reported the bug to QGIS issue tracking. For now, I upgraded to nightly build of qgis by changing sources.list as:
deb http://qgis.org/debian-nightly wheezy main
deb-src http://qgis.org/debian-nightly wheezy main
Then followed the steps of installation heading as described above and successfully install all three packages, i.e, qgis, python-qgis and qgis-plugin-grass. QGIS 1.90 – Master was installed successfully.
