If you wish to refresh your memory on granger causality, please read the following Wikipedia link: https://en.m.wikipedia.org/wiki/Granger_causality If you wish to refresh your memory on convergent cross mapping (CCM), please read the following Wikipedia link: https://en.m.wikipedia.org/wiki/Convergent_cross_mapping And please read the following link for an example of how CCM is applied to infer whether causation is bidirectional, unidirectional or etc: http://www.uvm.edu/~cdanfort/csc-reading-group/sugihara-causality-science-2012.pdf Below HERE ARE THE SIX Questions, divided into part 1 and part 2: PART 1 Question 1 A study is conducted to examine the relationship between median magnesium intake (X) and %all cause mortality (Y). Please read the study found on the following link: http://m.jn.nutrition.org/content/144/1/55.long?view=long&pmid=24259558 Analyse X and Y using granger causality. Based on your analysis, does X cause Y, or does Y cause X, or neither? Show the steps of the granger causality calculation which you used to arrive at your conclusion. Question 2 Using convergent cross mapping (CCM), analyse X and Y again. Based on CCM analysis, does X cause Y, or does Y cause X, or neither? Show your CCM calculation steps Question 3 Using CCM again, please state whether the causal relationship between X and Y is bidirectional, transitive, unidirectional, externally forced, or neither (no causal relationship) and the CCM calculations which you use to arrive at your conclusion. PART 2 Question 4 A study is conducted to examine the relationship between Resting heart rate (X) and %all cause mortality (Y). Please read the study found on the following link: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1446757/ Analyse X and Y using granger causality. Based on your analysis, does X cause Y, or does Y cause X, or neither? Show the steps of the granger causality calculation which you used to arrive at your conclusion. Question 5 Using convergent cross mapping (CCM), analyse X and Y again. Based on your analysis, does X cause Y, or does Y cause X, or neither? Show your CCM calculation steps Question 6 Using convergent cross mapping (CCM) again, please state whether the causal relationship between X and Y is bidirectional, transitive, unidirectional, externally forced or neither (no causal relationship) and the CCM calculations which you use to arrive at your conclusion.

For many years we have used my excel sheet to calculate prices on out steel buildings, now we want to make that excel sheet into a price configurator and put it on our website. The configurator should be able to: -Calculate price on the building based on the excel sheet - There shall be possible to add accesories to the building, doors, windows, gates etc. - Graphical animate the building based on the user input - The user shall be able to create an account, and there the user can see the projects he has calculatet earlier. - We want to be able to change prices in the backend. - The program shall be able to produce dfx files of the building. - User shall be able to save their project/building. So that they later can login and modify this project. - Administrator shall be able to open a project that is made by the user and modify it. - User shall be able to print the project, with drawings and prices. - Program shall animate the building based on the input of the user. 2d is most important, but 3d would also be nice. - Drag and drop placement of windows, doors and gates. - Program does not need to work on mobile devices. We have made 2 prototypez of the program. The program is made with unity. What is missing in the programs is: - more detailed graphics - Backend - DFX files - Has made to many compromises in the prototype. Please contact us for link to the prototype. For inspiration we have looked at : http://www.hts-industrial.com/configurator/ http://www.astron.biz/en/building-configurator/ http://buildingconfigurator.histruct.com/Component3D/?componentPrototypeName=Configurator_AgriculturalBuilding.fcc - This very advanced. It is not necessary for us to have it this advanced, still it would be nice.
