Hello,
I would like to dedicate some spare time to learn some new stuffs (self-learning), so I making a sort of planning (it would be something like 10 hours/week). There are two subjects I am interested in (mostly not as core skills but as transferable skills), but I am not sure which one to...
Hello,
Can someone provide me please with some pointers on how to convert Modbus analog input signal (Analog read from input register at specified address) to a 4-20mA value.
Modbus protocol can be RTU or TCP/IP.
Thanks in advance
If you plan an escape, you must succeed as if you fail, you...
Hello,
I have embedded in my FORTRAN main code a set of subroutines which are provided under Lesser General Public License. I intend to exploit the software code commercially and the source code is not to be disclosed. What are my legal obligations in this case?
- Am I required to provide the...
Hi,
I need some examples of centrifugal compressor data log / trending (inlet and outlet pressures, temperatures, speed, etc. vs. time) from plant historian / distributed control system (typically DCS/SCADA). This type of plant operation information is are often exploited by diagnostic and...
Hi there,
I have two questions:
- Is it doable to call a VB6 DLL from G95 Fortran? Can you provide an example?
- Could you also provide an example of calling VB.Net DLL from Fortran G95 too?
Thanks in advance
There is so much media focus nowadays on the global warming issue and the CO2 emissions. But I am wondering if global warming is not the tree hiding the forest. I read some articles that suggest that about 30% of the bird population have disappeared from North America since the last 40 years. I...
For centrifugal compressor, if I know (or can approximate or regress) a functional relationship (characteristics) as such
(work input factor) = F(Inlet flow coefficient, Mach number, impeller diameter) -----(1)
(polytropic efficiency) = G(Inlet flow coefficient, Mach number, impeller diameter)...
Hi,
My professional registration renewal CEng is due early on next year. A minimum number of CPD hours must be documented.
Have gathered about 65% CPD to document technical knowledge core skills (self-learning, online courses, project, etc.). This should be fine.
But I miss extra CPD's on soft...
Hi,
I am considering to take some freelance mechanical engineering jobs in platforms like Upwork or equivalent. I am resident of Canada.
My questions:
- Is it required that I obtain some kind of permit / license from authorities to do freelance job ? FYI, I am not licensed as professional...
Hello,
I have gas properties available from SRK or PR equation of state for mixtures such as
Entropy, enthalpy, Cp, Cv, isentropic volume exponent, density, compressibility.
Question: Is there a way to infer the 'isentropic temperature exponent' from combination of the above properties (by...
Hello All,
First of all, apologize for my ignorance on the topic but my problem is as follows:
I am trying to create a small program that fetches data from Modbus e.g. TCP/IP;
I've used a Modbus simulator available for free in internet. Now I try to make sure I can read the Modbus data from...
Hello,
I was wondering if someone would have a specific knowledge on this:
When someone makes its own implementation/coding of an equation of state (EOS) described in standards (e.g. AGA8 or GERG2008 described in ISO20765) is it legal? can there be patent rights associated with such EOS? I...
Hi there,
I just wanted to share some of my impressions after some extensive immersion into artificial neural networks in the context of regression analysis. True that neural nets are a powerful tool but like any tool there are limitations. I feel I still have a lot to learn in this field...
Hello,
Is there a way to measure/infer gas density (say in kg/m3 unit) using an orifice type of instrument / flowmeter (that is, based on Delta P measurement) ?
Example: If I have a gas line that is equipped with pressure, temperature instruments and a flow element device (orifice), is there...
Hello,
I am currently attending a workshop on resume writing (and interview skills). The workshop is offered for free to job seekers by the Province (Canada). Our teacher/coatch is an ex HR from corporate world...I decided to attend this headache workshop simply because it can result in some...
Hi All,
I am in the process of submitting an application to register as professional in Quebec, but I am still thinking if it is worth it or not, some points to consider:
- Foreign diplomas problem. As I have received my BS/MSc. degrees outside of Canada / and not part of the Washington...
Hello All,
I work with a multilayered artificial neural network (ANN) for purpose of doing non linear regression / universal interpolator.
It is a "classical " ANN whose topology briefly described as
-Input Layer (n neurons) -> X1, X2, ...., Xn Inputs
-Single Hidden Layer
-Output Layer (1...
Hello,
I would be grateful if I could gather some opinions with respect to the following:
I refer to centrifugal type of compressors / multi-stage ; as you know, when such type of equipment is involved, it is custom that the OEM / compressor manufacturer provides the performance data to the...
Hello All,
Sorry for this boring question...since this is a subject that has been quite exhausted ; problem is, I found myself puzzled by this:
Conversion from kg/h to Nm3/h should be quite straightforward exercise AS LONG AS we all agree on what is "Normal" conditions (vary from contract to...
Hi there,
I have a visual basic 2017 windows desktop application. The application calls a Fortran DLL. The Fortran version that is running is "gcc".
So when the Fortran DLL is being executed, its output displays in the Visual Basic Output Window. This appears to be working quite well.
Now what...
