    The PDF file is available on “Resonance Line Broadening of Alkali Metals in a Pyrotechnic Flame “. The PDF contains details of application of Radiative Transfer Equation to predict Radiative Power of a flare composition along with its physical properties. The PDF has a code in Appendix written in Basic, which has been successfully developed in Fortran and in Matlab. The Fortran code is for the input file generation, which will be used by the Matlab code, whereas the Matlab code predicts the Radiative Power of the flare using the methodology given in Radiative Transfer Model as in PDF.Some of the documentation is done upto 80-90% in respect of Power point presentation and a report is made on the same documentation, the report is 80-90% complete,An Expert is required to revise the documentations in respect of Project_1 and complete the documents i.e. Power Point Presentation and Report document in Word Format….In respect of roject_2, Power Point Presentation is available for the expert to a understand the procedure used to develop the Fortran code, An expert is required to write a report on Project_2. The PDF is also available which will give details of theory and numerical calculation process. Expert may refer the PDF also. Expert has to write a report on functioning of the fortran code as described in PDF.Documentation will be similar to PDF provided in respect of both the Projects , only expert has to revise it and understand it and make it understandable to reader in easy way + Explain the method followed by the code with justification of theory of PDF files.

    Below are the information for the Kalman filter assignment. The question 1 consist of a theoretical part where from the y and z positions and the y and z components of velocity, the state vector and measurement vector needs to be writen. For a kinematic propagation model, the matrices needs to be determined, measurement model, propagation covariance and measurement covariances as well.Every aspect needs to be mathematically developped (for an easy understanding)An example of the of what is required is given page 37 (slides 162 to 164) but it need further explanation.of the &quot;Sensor & data fusion&quot; ch4-6-2014&quot; Question 2 consist of creating a Kalman filter in Matlab following the algorithm example given in page 28 (Slide 145) or page 48 (Slide 184) Justifying the use of that method over the algorithm 1 (The Matlab code must be also explained briefly). Then using the data given on the file SDF2013a.txt prove that it is working. Question 3 Add rate to the measurement vector previously found and justify teh revised filter design (including initialisation) and evaluate the effect of the change on the position estimates obtained with the data of SDF2013b.txt. Assume the range rate measurement model is R(dot) = - z(dot)sin alpha, where sin alpha =0.13100062Question 4. The north-south motion can be approximated by simple harmonic motion with angular frequency omega = 2 Pi / Tday, where Tday = 86164 s (1 sidereal day). Use this to develop a model for a dynamics-based propagation model of the z and dz/dt components, modify the filter of part 3 with this change, and then use the new filter to re-process the data of SDF2013b.txt. Show and discuss the results.

    A Reaction Wheel Pendulum is a standard topic in most physics courses because it includes some physical subjects such as the simple harmonic motion, the period of oscillation, the acceleration of gravity, the center of mass, the moment of the inertia and momentum. The reaction wheel pendulum adopted in this project has a motorized propeller at the center of wheel so it can lift the pendulum after given voltage. This concept of pendulum system is useful and can be applied in real life. The reaction wheel pendulum system has many applications such as measurement, scholar tuning, coupled pendulum and entertainment.The control problem in driven pendulum system is controlling the pendulum behavior, such as the stability, rise time and overshoots with adjusting the given voltage.LQR controller is Linear-quadratic (LQ) state- feedback regulator for state-space system, appropriate matrix Q and R to enable system to achieve optimal stability by modifying weights in the matrix Q and R corresponding variables. The purpose of this project is to design LQR for stabilizing a reaction wheel pendulum. The pendulum with this controller reaches a steady-state angle with desired transient response.

    I have a casted metal fitting at the end of a hydraulic hose that I want to reproduce. It is not a shelf item. I assume its a hydraulic hose fitting that was a limited design but I would like to (produce) or make this fitting. Please see the attached pictures. As not to waste time I&quot;d like someone to work on this that has experience making CASTED METAL MOLDS. The most important thing here is I need to have the hose end pictured in the attachments. The problem with this fitting is its very cheaply made and falls apart usually a year or 2, the fitting breaks away from the hose. I need a fitting with the same specs but a much stronger design to connect to the hose. I need to be able to make the entire assembly using my own swedging machine.VERY IMPORTANT --(Winning bidder must be able to provide details on how to attach the new fitting). This fitting is used as a return so not a lot of pressure runs through it but it must be able to handle the heat and pressure. Rumors are the main hoses carry 1600 psi, not sure what the psi pressure is on the return lines.I will supply the winning bidder with a model of the hose and a roll of thermoplastic hose I am not looking for speed but I am looking for a workable design. Last thing, I had someone working on this project that wanted to charge me $40/each for a working design. That&quot;s insane. That part here in the US would be about $5-7 each. Please bid accordingly.
