Hi all friends:

   I am an ABAQUS user and I have a question about LINUX ABAQUS.

   Actually, when i finish all defining precedures in LINUX ABAQUS and submit the job, the job status will always remain "submitted" and never "running",which means that my job is not calculated. And after several hours later, the message area will show me that my PC have idled for 3hours and my licensed will be checked in several minutes and several minutes later, the status still remain the same, i mean "submitted".

Strain Induced Growth Instability and Island Nucleation on Patterned Substrate

Submitted by fengliu on

thin film epitaxy

Strain induced self-assembly provides an attractive route to nanofabrication of semiconductor quantum dots on surfaces. Recent experiments have demonstrated that combining the strain induced self-assembly with surface patterning provides an effective method to further improve the size uniformity and spatial ordering of quantum dots. However, the underlying mechanisms responsible for such improvement remain poorly understood. Recently, we have developped theoretical models to elucidate the strain induced growth instability and island nucleation on patterned substrates.

Can a maruti 800 engine be used to construct a 10KVA petrol generator?

Dear All,

I am a mechanical engineer by education. This is just a research question. I was seeing a diesel generator employing an old mahindra tractor engine the other day and started wondering if a Maruti 800 engine would be able to work a 10 KVA generator, and wouldnt it be more fuel effecient (and cheaper to make) then one of the generators using an old diesel engine. Any thoughts would be highly appreciated.

Thanks,

Gagandeep Sethi

 

ABOUT Work done by a pressure applied to a system

Work done by a pressure

I have one question  about work done by a pressure applied to a system.  The book of Thermodynamics often always present pdV (where dV is the change in the volume of the system. )but never Vdp, Why is that? Is it because we don't treat p as a variable? In a grand canonical ensemble is pressure constant for any system?

Acording to Thermodynamics first law,  du=dq-dw , where dw denotes work done by pressure and external force.  dw=pdv+dw' .   dq=Tds (Thermodynamics second law)

so, dU=TdS-Pdv-dw'
