    B.Sc. Physics, M.Sc. Engineering - Mistake?

    Thanks Jghrist, I have already checked the PE requirements and I do qualify, but the problem right is no companies are contacting me for an interview. Is it probably because my BSc. is in Physics? I can't understand any other reason why they wouldn't to be honest. I am only applying for...

    B.Sc. Physics, M.Sc. Engineering - Mistake?

    Hello, I would like to know everyone's opinion (preferably from those with hiring or first hand experience) regarding my chances of employment as an electrical engineer in the power industry, primarily with electric utility companies. I received my B.Sc. in Physics from Wayne State University...

    Regression Analysis - Constructing a model with constraints (Need help please)

    That's correct liteyear, basically however much the function increases or decreases it must be compensated for within the x range. I must admit I have very little knowledge in C-language. I can see by the code it seems to take into account min and max points. So if these min and max functions...

    Regression Analysis - Constructing a model with constraints (Need help please)

    It shows the attachment on my post for me. Does the figure not show up for you? Here is the link I used: http://i61.tinypic.com/so0qx1.jpg

    Regression Analysis - Constructing a model with constraints (Need help please)

    Hello, I am trying to construct a general function/method based on two sets of minimum/maximum data point constraints, which can take on new values in different situations. The only known data for this general function is the starting point (y-axis intercept) and the x-range. The rate of change...

    Help - Gas Network Operator Handbook?

    Thank you, I downloaded the UNC from the link you posted.. I'm not sure how much info there will help me, but I will look through it closely. I was afraid what you said may be true. This information I'm seeking does seem to border on the line of confidentiality, but I'm still in disbelief that...

    Help - Gas Network Operator Handbook?

    Okay so it seems by the responses I've received, that a gas network operator isn't typically directly involved with considering the physical constraints of the system. But they are responsible for controlling the flow of the gas correct? To control this gas flow you must know proper/safe...

    Help - Gas Network Operator Handbook?

    Here are some of the basic questions I'm still searching to understand both conceptually and mathematically: 1. What can you do to control/vary the pressure level and mass flow? Which tools can you use, without influencing the customers? 2. What happens to the pressure level/mass flow when you...

    Help - Gas Network Operator Handbook?

    Thanks for the reply Austsa. Just to clarify, I am only researching the transmission of natural gas at high pressures. I was thinking about trying to dig up some journals or possibly contacting companies directly for this type of information. Any recommendations would be greatly appreciated.

    Help - Gas Network Operator Handbook?

    Thanks BigInch, I appreciate the detailed response. I'm looking for any source material that I can academically reference, which has information similar to your response possibly with mathematical formulas used to assist network operators in making cost efficient/technically optimized decisions..

    Help - Gas Network Operator Handbook?

    This has proven to be a challenging task.. I can't seem to find any technical literature regarding the responsbilities and decision process taken by a gas network operator. Would anyone have any other recommendations? Should I try to get in contact with gas companies? I'm at a loss for ideas...

    Help - Gas Network Operator Handbook?

    Hi, I am looking for a good handbook which details the responsibilities of a gas network operator ideally in different gas grid states.. For example, what are the degrees of freedom the operator has? If the pressure is too high in one part of the grid he may open another branch, use a storage...

    Need Help Finding Good Book - Natural Gas Transportation Systems

    After talking with a colleague of mine, I was just informed the www.psig.org website has moved their technical papers to a new website called "onepetro.org" where you are now forced to pay :( This is a shame because I am just starting my master thesis and I've heard this website was really one...

    Need Help Finding Good Book - Natural Gas Transportation Systems

    Hello, I am in desperate need of a good book which contains load flow problems and different gas grid scenarios preferably using the Darcy Weisbach formula to calculate pressure values, etc. I am also trying to find a good book that details the responsibilities of a gas network operator on a...
