Am doing a project which is about thermal management of the 18650 lithium-ion pack. I am currently simulating the model under natural convection. But I am supposed to run under forced convection. How/ where can we find forced convection in Dymola

You can use Modelica.Thermal.HeatTransfer.Components.Convection but you have to provide a value/equation for the thermal conductance Gc using a correlation from a textbook that fits the flow situation e.g. flow around / along a cylinder.

They both seems to store files in a decentralized network. So what's the difference between them in terms of data structure and algorithms they use? And also what's the difference between them in terms of use cases?
If I store a file in IPFS or Filecoin, will it remain there forever or it may get lost?
IPFS does storage and content-based addressing. Filecoin is just a way to incentivize people to store IPFS content.
So it's not really easy to tell the difference because they are not comparable. Filecoin just works on top of IPFS.

I see references to BaseMosaic in the NVidia X Server Settings applet, and in my xorg.conf, but I can't find a good description of it. What is it, and what does it do?
Mosaic is the way nvidia handles multiple GPUs and monitors.
BaseMosaic is when using separate GPUs without SLI, as there is also SLI Mosaic.
See Mosaic and SLI Mosaic for more detailed information

I want to know what was the first version of GCC that supported Objective-C ?
Yep. I see this question as likely to be moved to meta or something.
But in any event, the answer you want is 1988.
(which I found by looking in Wikipedia under the "Popularization through NeXT" section)

The company I work for is about three and a half years old but we haven't started developing software until recently. Is the less than three years old rule absolute or will they make exceptions?
I don't realy know if that's the reason you are interested in bizspark but if you sign up for the free software through this:
http://www.asp.net/downloads
and then follow the links on the e-mails, you can get legitimate copies/keys of the software!

Do I have to pay license costs for reading / manipulating PDF's on a server to adobe?
Not unless you use adobe software. Pdf is an open standard and many open source libraries that create/read/manipulate pdf files exist.
