I translate professionally between several languages. This includes 100% manual translation using a correct vocabulary and style (no automatic translation!). I would be happy to provide samples of my work. Some work is done by my trusted associates with whom I have worked for years and whose work is of impeccable quality. They are professional translators and native speakers of the language they translate to. I do NOT outsource any work to random freelancers. I translate FROM any of French, German, Swedish, Finnish, Russian, Ukrainian, Bulgarian, Polish, and English, TO any of German, Swedish, Finnish, Russian, Ukrainian, and English. Please see reviews in my profile for translations that I did here at freelancer.com.
Translation: English French German Russian Polish + more

I was asked to process and classify hundreds of recorded ECG curves in Matlab. I developed a custom classification method based on Shannon-Markov entropy (a notion of the information theory) and I wrote Matlab codes to implement my method. Then I was able to map each curve onto a color-labeled point in a 2D graph. This made it easy to see which curves are similar or dissimilar to each other, which was the purpose of the project.

I\'ve done a lot of tutoring, homework consulting, and test/exam assistance in several college subjects: maths (Calculus 1,2,3, Algebra, Linear Algebra, Differential Equations, Complex Variables, Probability), Physics (Mechanics, Thermodynamics, Electromagnetism), Mechanical Engineering (Statistics, Vibrations), Polymer Science. With my help, my employers were usually able to raise their grade to 90% to 100%. See the reviews for some projects that I completed.

Within this project (see https://www.freelancer.com/jobs/Matlab-Mathematica/discrete-optimization-using-mathematica/), I wrote Mathematica codes to implement 5 different financial math models described in scholarly papers such as http://mpra.ub.uni-muenchen.de/21913/\\n. My codes made possible automatic portfolio optimization with the account of nonstationary market behavior.

In this large project ($1500, see https://www.freelancer.com/jobs/Excel-Mathematics/Convert-math-proofs-Excel-formulas/) I converter over a dozen of advanced math equations from scholarly journal articles (such as http://onlinelibrary.wiley.com/doi/10.1002/fut.20291/abstract) to easy-to-use Excel calculators. The user would not need to use any specialized computational platform, but simply enter his market data into an Excel spreadsheet and have all calculations on pricing VIX futures done for him by Excel automatically.

Project for cugamelover -- 6
He's the best:) Always professional...Always on time [05 October, 2016] Have turned to him many times now, and every time he has been a clear communicator who is quick to respond and produces what I need...No matter what the job is, I offer it to him before making it public first. [24 August, 2017] Never lets me down! [18 March, 2018] Made quick work of it as always!...He is highly skilled with Excel.
