I need a simple 3D heat transfer solution for cooling of a 1 cubic km block ... T = 993 Kelvin, Specific heat capacity = 1.48 kJ kg^-1 K^-1 Thermal conductivity = 2.6 W m^-1 K^-1) Density = 2830 kg/m^3 ... to 643.15 Kelvin inside another solid with a temperature of 643.15 Kelvin (assume they have the same thermal conductivity and specific heat capacity) The answer should be in years. You will deliver: A thoroughly documented solution that starts from ... ∂/∂x(k ∂T/∂x) + ∂/∂y(k ∂T/∂y) + ∂/∂z(k ∂T/∂z) = ρCp(dT/dt) ... where each step is shown, as if you were teaching a small child.

Hello, I need to get made a Java script. I will give you the APIs, and the software to debug the thing you are making the script for. This is a very simple task and shouldnt take more than 10 hours for a skilled java coder. It needs to do a list of features which i will give you when we start the work. It will be a fixed price, and should be done within 2-3 days atleast. Hope to hear from somebody soon. ONLY APPLY IF YOU ANSWER MESSAGES, ALSO DONT APPLY IF YOU ARE NEW TO JAVA SCRIPTING, AS I NEED ONE WHO CAN EDIT IN API'S AND MAKE THEIR OWN ETC. This is maybe advanced for some but easy for others.

I'm looking for an experienced data scientist who has had some experience working on process optimisation (engineering related) problems. My data set is from a power plant desulphurisation process which has approx. 100,000 observations and 30 variables (including power). Using this data set, I would like to model the behaviour of power consumption with respect to the other variables. Then based on the derived model, find the optimal solution at which power is minimised subject to a few inequality constraints. This is an interesting problem and I'm confident that whoever takes on this challenge will find it rewarding! Practical experience in Neural Network Modelling, Nonlinear Programming and R will be considered favourably. If selected for an interview, further details about the project/expectation will be provided. I look forward to receiving your application.

I have just submitted my dissertation but my committee feels as though the boundary conditions of my models and of a few analytical solutions are not "defined clearly enough" in the paper. I feel as though I DID describe them, so I'm not 100% what they want. What you would do: Look at TWO models in COMSOL and extensively define their boundary conditions for me. (You don't have to have COMSOL installed - I can send you screenshots of how I've set it up). Look at one analytical solutions for heat transfer and define the boundary conditions and assumptions associated with them. You will write this up for me in Word - I am hoping a comparison between what I wrote and what you write will expose what I am missing in my report.

We are creating a new type of dating app that looks to compare people's traits and find out who is compatible. There is a text specification and a full wire frame that includes full details on how to match people. This formula is outlined on how to match people, and work out the compatibility. We need someone skilled with math to turn this text description and diagram into a math formula, that we can then give to our programmers. We are currently looking for someone who is really good in creating formulas based upon mathematics for our programmers to then use, so they can then writ the code to help identify who is a good match for who. Please list examples of previous work you have done that is like this? Also explain how you would approach this task? If we like your work, we have regular projects we'd get you involved in. Thank you
