    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.

    Hello,I am currently working on my Dissertation for the MSc in engineering. My project is about a Battery Pulse Charging (fast-charging) technology. Therefore, I need to model a Lithium Battery to investigate the charging performance and heat-development. The modeling should be done with Matlab Simulink.However, my background is in mechanical engineering and I have no experience with this softwares. I need support for the modeling the Charging system circuit.The battery that should be modeld is a NCR-18650 Panasonic. I want to simulate the following.- Charging the Battery at very high current pulses. The pulse has a short duration (the duration should be adjustable, e.g. between 0.01sec - 2sec)- Between the pulse is a pause of some seconds, in order to cool down the battery.- I want so show a graph of the Voltage and the current during charging- And I want to show a graph of the Temperature during the charging process. This is dependent on the internal resictance of the battery.-The Idea behind it is to optimise to pulse and the pause duration in order not to overheat the battery. Two related papers are atteched. Thank you in advance.Regards,Leo

Panel A analyzes the relationship between CGQ and ROA, panel B analyzes the relationship between CGQ and ROE, and panel C analyzes the relationship between CGQ and stock returns. As ROA and ROE are based on an annual basis, the corresponding CGQ should be on an annual basis as well. Therefore, CGQ in panel C should be on a daily basis as stock returns are. And the regression will be implemented through SPSS. we need 5 paper to confirm the ordersand proposal of 3500 words due by 10-JulyFull dissertation of 14500 words due by 1-sept.with each stage progress need to revise and carry on with satisfactory progress made

    I would like somebody to write a programming code in MATLAB for this fairly simple task, its to model an insulin regimen, that simply takes a value of an impulse in insulin U unit and the plots the insulin flow concentration over time Iex (U/min). Don&quot;t get put down on the unfamiliar units the regimen works fairly the same as when you take your meal (this is the impulse) and then your blood glucose starts increasing over time and decrease at the end (the concentration). This involves a coupled partial differential equation of which I&quot;m not at all very familiar with. There are 2 types of insulin which is Rapid Acting (R) and Long Acting (L) insulin, the former will produce a rapid response while the latter with a steady and longer response. This depends as well on the value of insulin which varies between 3 to 20 U/ml. The plot should follow fairly or more or less the plot in Figure 3.15 in &quot;Insulin Regimen&quot; paper attached with the correct unit of time (minutes/hours) and exogenous insulin flow Iex (U/min).I attach the papers which explains all the parameters and constants. One named &quot;Insulin Regimen&quot; is already sufficient for this task but I attach as well the original paper referred from it named &quot;Comprehensive Pharmacokinetics&quot;. They only need a proper programming, an impulse and you should get the simulated graph shown in the article when modelling this. I prefer that with the code I can set the input to be just the type of insulin whether it is R or L and value of insulin applied.It&quot;s very doable, I have done it with the carbohydrate regimen but I don&quot;t have much time for this one especially since I don&quot;t know much about PDEs.Please do ask anything if you are unsure.Thanks a lot and I appreciate anyone who can help with this.
