I have been asked to determine the "shock regime" of a oblique shock / bow shock interaction based on the angle of the impinging shock and flow conditions. What does this mean? My initial thoughts were that I was being asked to determine whether the shock was strong or weak, but since the...

I see the merit in your criticisms, and I'm now worried that I've over-trivialized the problem with my assumptions. I could go back to the drawing board and develop a model that will produce actual predictions for the values of the numbers, along with the likelihood of accuracy. However, getting...

Yes, this is somewhat of an issue. I tried to address this earlier by simply adding the assumption that the fluctuation in currency can be assumed to be small, such that a "kelly bet" does not exist because risk of total loss is 0. I think so. Let's suppose you have $100 of cash. The model is...

Currently the only information I have available is that the values will either rise or fall. The amount is not specified. Let's, for now, simplify it to make the amount irrelevant. Suppose you have $1, and I tell you the following: 1) That there is a chance higher than 50% that the Australian...

Thanks for the response Stephen. Sorry for highjacking symbols. Let me rephrase it so it's clearer. Let's call the two 1D arrays (vectors?) PRED and DATE respectively, where PRED contains a list of binaries representing the prediction and DATE contains integers specifying the number of days...

Hi everyone, I realize this is only loosely related to mathematics, but I didn't know where else to ask this question (if I post it in a finance forum I'll get 100 different answers from people who probably didn't really understand the question). I think mathematicians are the kind of people...

Hi Guys, I'm building a numerical Matlab simulation of a thermochemical heat storage device (using zeolites), and need to update the state of water vapor in the device at every time step. My question is, if I have an empty space with water in it, with temperature, pressure, density, etc. all...

Thanks, would you know how I can get a quantified answer? I am trying to create an approximate model for the performance of such a system and would like to know what efficiencies I can expect. Do you know of any empirical relations that quantify these relationships? I'm not looking for carnot or...

Hi everyone, sorry about the vagueness of my question, but the fact is that I simply don't have enough info yet to decide which type of turbine I want to use. As mentioned, all I have is a heat storage device (in this case zeolite cells), which can output heat at temperatures ranging from 100°C...

I am trying to assess the feasibility of running a steam turbine from a heat storage device, which can produce in a heat range of 100°C to 600°C (with a respective increase in cost, to be compared with losses in efficiency of the turbine for lower temperatures). So my question is this: Where...
