I need immediate help with my SIMULINK model. I don't know why but no matter how much a increase or decrease Kc or TI, the graphs are the same. C'A0(s) is the disturbance going through G'D(s). Please check my transfer function blocks by taking the laplace transform of the equations. Any suggestions is welcome greatly! thanks

automata theory can please wright the exact language it know for example say it knows strings start 0 and end with 1 this is as example also as regular expression

Problem 1 = = = 13,600 Manometers can be used in combination with cardiovascular catheters to measure blood pressure based on height differences. In the example in Figure 1, the manometer contains two fluids: water (density p 995 Kg/m³) and mercury (density pm Kg/m³). The density of blood is p 1,060 Kg/m³. Assume that there is atmospheric pressure at the interface between mercury and air. The interface between mercury and water is at z₁ = 7 cm, the interface between water and blood is at Z2 27 cm, and the tip of the manometer at za 10 cm. Recall that the fluid statics equation is dp/dz-pg 0, when the z axis is taken pointing downwards. a. What is the gauge pressure po at the interface with air, in mmHg? (5 points) b. Calculate the gauge pressure ps at the tip of the manometer, in mmHg. (5 points) N Z37 blood ப Zz Water Mercury Zo 3=0 z Figure 1. Manometer for blood pressure measurement.
