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 need someone to research and modelling certain aspects of microstructure within high frequency trading. Preferable knowledge in these topics: Fokker-Planck (diffusion) equation Queue dynamics Markovian dynamics Brownian motions discrete Poisson model Monte Carlo Typical paper example here http://arxiv.org/pdf/1312.0514.pdf You do need to have trading experience. If you wish to learn this topic and have the mathematical knowledge then please ask and we can discuss, I am open to exchanging knowledge for modelling development. Would suit a university lecture based candidate. I have further jobs for good candidates. Coding prefer in Python, C, or Matlab.

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

Our project needs an Android developer capable of creating more complicated mathematical algorithms than it is usually required for commonly used apps. GUI part of our application is quite simple. But we need also a skill to be able to make some animated instructions for users help. Candidates that have university degree in mathematics have higher priority. We also prefer to work with developers from the ex soviet block.

The project includes reading a detailed analytical approach including Gaussian mixture models with a dynamic baseline and N-way ANOVA. We need someone who can critically assess the plan and help identifying flaws in it. Next to criticising our current approach, you should be able to formulate your opinion with regards to other solutions that might work. You won't have to implement anything, but the plan should be as detailed as possible, so a Python-developer without deep statistical knowledge should be able to implement it. We need someone with a strong understanding of probability theory and statistical models. Our methodology document is fairly complicated already, so unless you are proficient with Mathematics and have a strong understanding of gaussian mixture models and how they are usually implemented, please do not apply. It is crucial that the person oversees the entire field, and can not only find a working solution, but can identify what is the BEST approach. Familiarity with...

The related patent application entitled "System for Harvesting Seaweed and Generating Ethanol' represents a lightweight drone harvesting head tethered by a hose transport system to a much heavier primary ocean vessel. The first part of the concept involves using a much smaller mass than the primary ocean vessel to harvest in a pendulum like motion through the water, thereby moving much less mass than a conventional seaweed harvesting vessel during normal operations. The second part of the concept involves juicing the harvested kelp aboard the primary ocean vessel and then subjecting the juice to high pressure inside a reverse osmosis filter, thereby separating a great deal of the entrained water without losing dissolved solids. Transporting a concentrated pulp to a fermenter and distillery instead of the entire kelp seaweed mass should dramatically improve the efficiency of the system by minimizing energy consumption. I am seeking an individual that can mathematically estimate...
