We currently do materials takeoffs in-house and we are looking to outsource. Estimated time for takeoffs vary between 45 minutes to 2 hours. We are looking to pay $50 for each completed takeoff. Assignments would be ongoing. We have attached a completed Takeoff and corresponding Excel Spreedsheet to show what we need.

Maximum Power Point Tracking in Doubly Fed Induction Generator using Tip Speed Ratio Control algorithm The idea of this project is to make a simulation and evaluation for one of the MPPT algorithms during wind conversion process, which is Tip Speed Ratio Control algorithm. the type of the generator is vector control and the type of the converter is back to back (AC-AC). the parameters of both generator and wind turbine are given in the attached files in "Parameter. Pdf" the simulation must be performed in MATLAB simulator (code or Simulink ) A report that discusses the mathematics equation of the model and discussion for the obtained results are also required.

Imagine someone singing in the shower. The sound bounces around the bathroom and the shower, the sizes of which create resonances we call standing waves. Those standing waves are at particular frequencies because of what we call the speed of sound. I want to convert any given physical distance -- like the size of a shower or bathroom, or the length of a concert hall -- to the Hertz/pitch of the fundamental standing wave of both a) sound and b) light for that distance. Please provide a wee command-line program (and source code) that answers this question. I prefer Python, PHP, and Lua, in that order. Future/extra credit: Please also compute the first N pitches of the harmonic series from that fundamental.

I need data analysis with solid results. I attach the data file herewith. From the data, triangular periodic function has to be developed. NDPK concentration in x axis, absorbance in y axis. a zigzag graph comes automatically in excel graph. The graph found from data is triangular periodic graph. The triangular graph's properties have to be analyzed. The parameters of the triangular graph has to be defined and elaborated. The comparison is between- 1. Standard 2. MCF-07 breast cancer cell line 3. MDA-MB-231 breast cancer cell line No control data available. 10 ng/ml has to be used as baseline.
