Nonthermal Emission from Star-Forming Galaxies

open access: yes, 2013
The detections of high-energy gamma-ray emission from the nearby starburst galaxies M82 & NGC253, and other local group galaxies, broaden our knowledge of star-driven nonthermal processes and phenomena in non-AGN star-forming galaxies.

Investigation of feeding devices and development of design considerations for a new feeder for micro-sheet forming [PDF]

open access: yes, 2008
Recent review in micro-forming research and technological development suggested that the trend of the development is more focused on the manufacturing processes, machines and tooling, and efforts on the methods and systems for integrated precision ...

Experimental and numerical analysis of micromechanical damage in the punching process for High-Strength Low-Alloy steels [PDF]

open access: yes, 2014
Sequential sheet metal forming processes can result in the accumulation of work hardening and damage effects in the workpiece material. The mechanical strength of the final component depends on the “evolution” of these two characteristics in the ...

FE analysis of multi-cycle micro-forming through using closed-die upsetting models and forward extrusion models [PDF]

open access: yes, 2007
Research in micro-forming leads to the investigation of the effects of heat generation in the workpiece and temperature changes in the tools during the forming.

Dynamical Formation of the GW150914 Binary Black Hole

open access: yes, 2016
We explore the possibility that GW150914, the binary black hole merger recently detected by Advanced LIGO, was formed by gravitational interactions in the core of a dense star cluster. Using models of globular clusters with detailed $N$-body dynamics and

Efficient Robust Optimization of Metal Forming Processes using a Sequential Metamodel Based Strategy [PDF]

open access: yes, 2011
The coupling of Finite Element (FE) simulations to mathematical optimization techniques has contributed significantly to product improvements and cost reductions in the metal forming industries.

Vision-aided Monitoring and Control of Thermal Spray, Spray Forming, and Welding Processes [PDF]

open access: yes, 1993
Vision is one of the most powerful forms of non-contact sensing for monitoring and control of manufacturing processes. However, processes involving an arc plasma or flame such as welding or thermal spraying pose particularly challenging problems to ...

Warm Deep Drawing of Aluminium Sheet [PDF]

open access: yes, 2003
Aluminium sheet drawing processes can be improved by manipulating local flow behaviour\ud by means of elevated temperatures and temperature gradients in the tooling. Forming tests\ud showed that a substantial improvement is possible not only for 5xxx but

Survey of the diagenesis process and effect these process on reservoir quality of the Kangan formation in South Pars Field [PDF]

open access: yes, 2009
Kangan and Upper Dalan formations are forming reservoir sequence of the South Pars field. Litology of the kangan formation is carbonate and (limestone and dolomite with anhydrite intervals), so digenetic processes were very active in this formation and ...
