Semi-solid processing (SSP) is a popular near-net-shape forming technology for metals, while its application is still limited in titanium alloy mainly due to its low formability. Recent works showed that SSP could effectively enhance the formability and mechanical properties of titanium alloys. The processing parameters such as temperature and forging rate/ratio, are directly correlated with th...

This paper presents a comparative study of Continuous Stirred Tank Reactor concentration control using Particle Swam Optimization and Bacterial Forging Optimization. Continuous stirred tank reactor plays a very important role in process industry. This paper presents the optimal design of PID controller based on Particle Swarm Optimization and Bacterial Forging Optimization. The first step is th...

This paper describes the possibilities and conditions of the closed-die flashless forging process using conventional mechanical presses and equipment. The technique of driven gear forging with an internal flash or with special die design has been developed. The quality of forgings is comparable to that achievable on Hatebur presses. Furthermore the problem of how to increase shift production un...

This short report summarises the proceedings of the international symposium "Precincts, people and places - forging new partnerships", held in Brisbane on 24 and 25 July 2009.

Labour economics is often taken by vivid discussions about the specificity of the labour market and the need to develop a different approach, away from the current standard microeconomics. What is often forgotten is that this was not always the case. Labour research in the interwar years was quite different from what we regard presently as labour economics, being much more broadly and loosely d...

Background & Aims: The orbital cavity is an important anatomic structure in the face. It is in close connection with the skull, paranasal sinuses, and the nose. Precise knowledge of the orbital cavity dimensions can be helpful in the diagnosis and treatment of diseases associated with the orbital cavity. Due to the lack of adequate research on orbital size in Iran and the city of Kerman, the ai...

This paper describes new conditions on parameters selection that lead to an efficient algorithm for forging ElGamal digital signature. Our work is inspired by Bleichenbacher’s ideas.

Oxygen content in aluminium alloys Al-3Fe or Al-8Fe-lZr (wt%) maked from air atomized powders by a sinter-forging

Abstract Forgings are produced in several process steps, the so-called forging sequence. The design of efficient sequences is a very complex and iterative development process. In order to automate this reduce time, method presented here, which automatically generates multi-stage for different geometries on basis component geometry (STL file). was developed closed die forging. individual modules...
