Mathematical Formulas - includes linear algebra

Fixed-Price - Expert (\$\$\$) - Est. Budget: \$25 - Posted
Hi There, I am looking for someone to work out some mathematical formulas for me. I would like to know all the formulas used on this website - http://www.trickybet.net/lay-calculator. Some of the formulas are quite basic and some a little more complex – for example linear algebra. I also have a few extra formulas related to the website that I would like to know. Please let me know whether this is something you can do and how long it would take.

Analytically minimize operational costs, equipment cost and to short payback period of investment

Fixed-Price - Intermediate (\$\$) - Est. Budget: \$250 - Posted
Looking for experience industrial engineer or specialist in operation research to solve minimization problem. Background: This work aim is to minimize operational costs, equipment cost and to short payback period of investment. Scope of work: 1. Analytically solve the model (marked with yellow), which means to show which optimal S1 and S2 minimize the PBP while taking in consideration the constraint. If it is required- show convexity, linearity and infinity of the functions. * 2. Analytically show and explain in which scenarios of minimum PBP: S1<S2, S1>S2, S1=S2.* 3. Optional (or should be priced separately): To write MATLAB code for demonstrating by sensitivity analysis both operational and capacity planning stages: a. The whole equations for operational stage will be supplied, including excel file with all indexed "i" parameters (8760 hours in one year). Those parameters should be imported to MATLAB to matrix. b. Graph 1: Sensitivity analysis for "hi" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps (i.e 0.7h, 0.8h…1.3h) influences on the annual production by sub-system 1 and by sub-system-2 "X1, X2". c. Graph 2: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the production hours "i" of isubsystem-1 and isubsystem-2. d. Graph 3: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the payback period. e. Graph 4: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the equipment capacity S1 and S2. f. Graph 5: Sensitivity analysis for "hi" values: to check on the operational stage how the values of "h" 0.7-1.3 by 0.1 steps influences on the savings . *every step should be shown with explanations and any math phrase should be typed by "Math type".

Survey Analysis + Holisitic Marketing Strategy

Hourly - Intermediate (\$\$) - Est. Time: Less than 1 month, Less than 10 hrs/week - Posted
What we need is someone who is not only skilled in analyzing data, but knows how to apply it strategically to various digital marketing channels in a holistic fashion. All of the difficult work of creating a survey, obtaining statistically significant results, cleaning, visualizing the data, etc has been done. We just need someone who can tell us how to use the data to meet our goals. This will take some back and forth with me, and creating more visualizations within Qualtrics. It might also mean comparing the results with our AdWords data. I need someone who can really listen to my rather unique concerns and help us get what we are intuitively after. Background: I manage the strategy for EarthSharing.org an outreach website aimed at creating more people who believe that land value tax is a desirable and important policy for ending poverty and saving the environment. I need someone to first compare our existing survey results, preferably using Qualtrics, to the academic theories of Dan Kahan, a professor at Yale. The theory is called Cultural Cognition, which puts respondents into 4 buckets. This theory is useful because of its power to predict how people will answer many questions about society, beyond the 5 questions in the survey. We already have broken the responses into these 4 buckets the best we can, but I can't help but feel that we need to dig deeper. We currently receive \$40K in free advertising from Google AdWords for being a non-profit. We also have a newsletter. We have data from all of these activities. We need a 2nd opinion on our overall marketing strategy. We are juggling two goals, to identify as large of a chunk of society as possible who is likely to be interested in our ideas and to better market to them. Our other goal is to influence people in the San Francisco Bay Area who will attend our events and perhaps donate to our cause in a variety of ways.
