abstractor
A metal foam is a cellular structure consisting of a solid metal, For ex. aluminium, containing a large volume fraction of gas-filled pores.
The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).
The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces.
The strength of foamed metal possesses a power law relationship to it ....etc

Faurecia Exhaust Systems AB develops and manufactures exhaust manifolds for the car industry. In the developing process the FE-models are one of the main tools and they are becoming more and more important in the automotive development. In the tough competition between the manufacturers, the demands for fast development require good FE-models both from the manufacturers and their subcontractors.The main goal of this thesis is to update an existing FE-model of a close coupled exhaust manifold and look at the catalyst to investigate the behavior ....etc

INTRODUCTION


Metal foam is a dispersion of gas bubbles in a metallic bulk material
These are extremely lightweight materials
It contains 50% or more holes
They have some very promising properties

Structure o f metal foam
In metal foams cells are divided into distinct cells. the boundaries of these materials are made of solid material, the interior are voids.


Light weight Al foam
The best quality metal foams presently available
It has a density of from 300 to 1,000 kg/m³, th ....etc

Microsoft Access is a Relational Database Management System (RDBMS), designed primarily for home or small business usage. Access is known as a desktop database system because it's functions are intended to be run from a single computer. This is in contrast to a server database application (such as SQL Server), where it is intended to be installed on a server, then accessed remotely from multiple client machines. Microsoft (or MS) Access is a software package that you install just like any other software package, and is bundled as part of the ....etc

Hi,
Im sweatha, I'm doing my final year B.E..As I'm doing project on secure and practical outsourcing of linear programming in cloud computing.
Abstract of this project is shown below..
Cloud Computing has great potential of providing robust computational power to the society at reduced cost. It enables customers with limited computational resources to outsource their large computation workloads to the cloud, and economically enjoy the massive computational power, bandwidth, storage, and even appropriate software that can ....etc

Metal foam is a cellular structure consisting of a solid metal, frequently aluminium, containing a large volume fraction of gas-filled pores. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam). The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces. The strength of foamed metal possesses a power law relationship to its density; i.e., a 20% dense material is more than twice as strong as a 10% dense ....etc
