Figure in state-space where the output is OL(t). 8. Show that the system in the previous Figure in the text yields a fourth-order transfer function if we relate the displacement of either mass to the applied force, and a third-order one if we relate the velocity of either mass to the applied force. 9. Find the state-space representation in phase-variable form for each of the system shown in the Figure. 10. For each system shown in the Figure, write the state equations and the output equation for the phase-variable representation. 11. Represent the following transfer function in state space. Give your answer in vector-matrix form. 12. Find the transfer function G(s)=Y(s)/R(s) for each of the following systems represented in state space. 13. Use MATLAB to find the transfer function, G(s)=Y(s)/R(s), for each of the following systems represented in state space. 14. Repeat problem 13 using MATLAB, the Symbolic Math Toolbox, and Eq.

Gyros are used on space vehicles, aircraft, and ships for inertial navigation. The gyro shown in the Figure is a rate gyro restrained by springs connected between the inner gimbal and the outer gimbal (frame) as shown. A rotational rate about the z-axis causes the rotating disk to precess about the x-axis. Hence, the input is a rotational rate about the z-axis, and the output is an angular displacement about the x-axis. Since the outer gimbal is secured to the vehicle, the displacement about the x-axis is a measure of the vehicle’s angular rate about the z-axis. The equation of motion is: Jxd2Oxdt2+DxdOxdt+KxOx=JwdOzdt Represent the gyro in state space. 16. A missile in flight as shown in the Figure, is subject to several forces, thrust, lift, drag, and gravity. The missile flies at an angle of attack, a, from its longitudinal axis, creating lift. At the same time, the manipulator must provide sufficient force to perform the task. In order to develop a control system to regulate these forces, the robotic manipulator and the target environment must be modeled. Assuming the model in the Figure, represent in state-space the robotic manipulator and its environment under the following condition. a. the manipulator is not in contact with its target environment. b. the manipulator is in constant contact with its target environment. 22. In the past, Type-1 diabetes patient need to inject themselves with insulin three to four times a day. New delayed-action insulin analogues such as insulin Glargine require a single daily dose. A similar procedure to the one described in Pharmaceutical drugs absorption case study of this chapter is used to find a model in concentration time evolution of plasma for insulin Glargine. For specific patient State space model matrices are given by: Where the state vector is given by a. Find the system’s transfer function. b. Verify the result using MATLAB. 23. A linear, time invariant model of the hypothalamic-pituitary-adrenal axis of the endocrine system with five state variables has been proposed as follows: 4. In this chapter, we described the state-space representation of single input single output systems. In general, systems can have multiple inputs and multiple outputs. An autopilot is to be designed for a submarine in the Figure to maintain a constant depth under severe wave disturbances. We will see that this system has two inputs and two outputs and thus the scaler u becom es a vector, u, and scaler y becomes a vector, y, in the state equations. 25. Experiments to identify precision grip dynamics between the index finger and the thumb have been performed using a ball-drop experiment. A subject holds a device with a small receptacle into which an object is dropped, and the response is measured. Assuming a step input, it has been found that the response of the motor subsystem together with the sensory system is with the form: Convert this transfer function into a state-space representation. 26. State-space representation are, in general, not unique. One system can be represented in several possible ways. For example, consider the following systems: Show that these systems will result in the same transfer function.

Why I Dislike Popular Kids Essay

Why I Dislike Popular Kids Essay Free Online Research Papers Remember when you were young, in middle school, and there were all these preps? Well, I have a problem with the preps in my school. First of all, I have always wanted to be popular throughout my whole life. I have tried so hard to become popular, and nothing that Ive tried has worked at all. All of the preps in my school think that theyre better than everyone else, and they think that theyre the hottest things in the world. Well, theyre not. And most of them tell me that Im weird, that I need to get a life, and that I need to get better friends. Ive tried to get better friends, but I guess the only kind of friends Ill ever have are skanks. Second of all, most preps wont like you unless youre in a sport or youre totally gorgeous. Besides the girls being popular, there are guys that are popular too. Boys, now if there is a blonde girl that is popular, of course, they are going to want to date them. Boys think theyre all cool too just because they play football or baseball. Some are cool and nice, but most of them are jerks. If youre not popular, theres no point in trying hard to be popular, because it isnt going to get you anywhere. Thirdly, the clothing. Preps wear clothes like Aeropostale, Hollister, AbercrombieFitch, and American Eagle. If you wear these brands of clothing, theyll think youre cool. I wear Aeropostale and Hollister clothes sometimes, too, and yet, Im still not popular. But wearing these brands of clothing doesnt make you who you really are. They just make you look like a total prep. They have their moments though, too. Sometimes, when Im talking to one of the popular kids in one of my classes, at first, theyll listen, but then theyll stare off into space and dont even pay half attention to what youre saying. In conclusion, I learned that popularity isnt going to get you anywhere in life. All it does is just make you a total snob, and nobody wants to be around a total snob, especially me. I also learned that I dont need to be popular to have cool friends or a hot boyfriend. All I need is to have a nice personality and be friendly, and then Id get more friends. But preps are snobs and I just dont feel like wasting my time on them.

Industrial Revolution Essay Example | Topics and Well Written Essays - 250 words - 1

Industrial Revolution - Essay Example d politics, thereby stimulating varied other disempowered and marginalized sections of the society to strive for empowerment and a fair share in the national income. Capital emerged as the pivotal factor of production. This led to a greater polarization of opinion on both sides that are the labor and the capitalists, thereby both sections getting more organized and politicized. One negative thing about Industrial Revolution was that it envisaged earth as an external resource to serve as a fodder for the industrial engine of growth. In the long run it not only resulted in an irreversible depletion of natural resources and the commensurate pollution, but led to the contemporary challenges like global warming. There is no denying the fact that the map set by Industrial Revolution is not absolutely relevant in the current times marked by the emergence of new priorities like sustainable development and corporate social
