identification may result in unreliable prediction for complex systems where our understanding of the physics of the system is insufficient. Here we used a non-parametric approach as control of walking in humans is a complex task involving many degrees of freedom. We chose to perturb the system using visual perturbations as the input since the optic flow has a profound effect on the perception of speed. We measured muscle activations and kinematics as the output of the system. In linear time invariant (LTI) systems the relationship between the input and the output could be described in the frequency domain through frequency response functions (FRFs). In these systems an input with the frequency of f1 creates an output at frequency f2. The gain function of FRFs describes the relationship between input and output amplitudes and the phase function describes the timing information (i.e. lead or lag). Periodic systems like locomotion however are not LTI. Close to their point of operation these…
Fundamental Theorem of Calculus The Fundamental Theorem of Calculus evaluate an antiderivative at the upper and lower limits of integration and take the difference. This theorem is separated into two parts. The first part is called the first fundamental theorem of calculus and states that one of the antiderivatives of some function may be obtained as the integral of the function with a variable bound of integration. The second part of the theorem, called the second fundamental theorem of…
John Gutmann was one of America’s most distinctive photographers. Gutmann was born in Germany where he became an artist. He later fled Germany due to the Nazi’s because he was a Jew. Gutmann moved to San Francisco and re-established himself as a photojournalist captivating the lives of Americans. He mainly took photographs of people who were imperfect like himself because of his Jewish nationality. Gutmann targeted the poor, circus folk, the gay community and the rich. Two of Gutmann’s works are…
The fundamental theorem of Calculus: The fundamental theorem of calculus asserts the interrelated properties of integration and differentiation. It says that a function when differentiated, can be brought back by integrating (anti-derivative) or a function when integrated, can be brought back by differentiation. First theorem: Let f be a function that is integrable on [a,x] for each x in [a,b], then let c be such that a≤c≤b and define a new function A as follows, A(x)=∫_c^x▒f(x)dt, if a≤x≤b.…
the equation & based off what I did I'm assuming that his possible answer came out not to be an real answer to his problem & that is mainly because the equation itself is not true when eighty one is inserted for the letter x in the default problem. Okay so basically for this particular problem we have to think of f of x as basically the y value if that makes sense. So this would mean that if you use addition for the number two & + to the letter y we will see the function go up by two. The…
Story evaluation The story that will be evaluated is one entitled “Man was paid $2 500 to conceive a child with his neighbor’s beauty queen wife, but failed after 3 months trying”. Firstly, there is doubt in the story due to the source which is responsible for sharing the news. The source is a website known as 9GAG, which does not have any reputable evaluation system, and anyone is free to post a story he or she wants. However, judging by the comments on the post, many individuals assume the…
Educating is used when explaining the basic concepts of JP to Mrs. Hansen and coaching occurs when she transfers these concepts to cooking spaghetti bolognaise. The OT also adapts the JP strategies to suit Mrs. Hansen’s lifestyle. By making the intervention more relevant and motivating for Mrs. Hansen, the OT also employs their skills of engagement. To further this intervention, collaboration and consultation between Mrs. Hansen and the OT are needed to discuss the use of assistive devices…
Furthermore a 4-6 month rehabilitation plan was prescribed following surgery to reduce pain, limit swelling, restore range of motion (ROM), and regain maximal function. The patient hopes to resume full basketball activity within 6 months post surgery and to prevent…
Francisco Gutierrez 03.03 Linear Functions 1. The equation we have is 2x+3y=1200. The first thing you would need to do in the equation is subtract 2x to both sides. 2x cancels out and now we subtract 2x and 1200. You would end up getting 3y=2x-1200. Then finally, you would have to divide everything by -3. Your final answer for this question is y=-2/3x+400. Your slope is -2/3 and your y-intercept is 400. 2. So we know that our slope is -2/3 and the y-intercept is 400. You have one point on the…
New Balance is moving into a toning market with a pair of attractive shoes that has hidden balance technology. The purpose is to present, “Why walk when you can tone your body”, when you’re simply just walking or even doing your everyday chores. True Balance shoes promises 29% muscle activation and 10% calorie burn. Many women are getting intrigued with the idea of losing weight by these shoes from the percentages, but what if they percentages were lower. Would you still buy them? Even though,…
