Kinematics

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…

Animation is the method of taking still images and presenting them in rapid succession to create the illusion of motion. The contrast between animation and video is video takes constant movement and splits it up into frames. You have many different types of animation. Usually the main ones used are Traditional animation, Stop animation and Computer Generated animation. Traditional animation is created by drawing every frame by hand. Then these frames are coloured and scanned onto a computer and…

The concept of indeterminacy was proposed by a new generation of architects in the sixties and seventies as a way to assume and address the problem with the uncertainty of change during the life of a building. Seminal ideas, proposed in the sixties by the Archigram and its allies, promoted a novel architecture sympathetic to uncertainty, incompleteness and emergent situations. This shift in architectural discourse was further developed in the Seventies through proposing indeterminate kinetic…

The following first source focusses on precisely what it implies, barefoot running. The video clip compares the advantages of running with and without shoes. The video inaugurates with the author Ruben Meerman stating that due to absence of shoe usage in humans for hundreds and thousands of years, ‘some’ people may think that running without shoes how humans should be running by default (Meerman, 2012.) What catalyst has most likely attempted to do is provide these people with a second point of…

Title: 2-D Kinematics Purpose: The purpose of this experiment was to determine and relate the distance of a nerf-gun with a dart shooting out of it at an angle of 45 degrees. In addition, find the displacement and average acceleration of the dart as it shoot out of the nerf-gun. Hypothesis: If the dart is shooting out of the nerf-gun with choosing a small angle, then the distance will become larger, because if shooting at a right angle the dart is going to go straight up and then fall, but…

Weight Lifting Shoes As all knows that the apparel of an sports person varies according to the sports they plays. It is very much obvious when one talks about the shoes. For example the spiked shoes are mainly contrived for playing baseball. It is quiet impossible for anyone to play football with the spiked shoes that are meant for playing baseball. So it is very much apparent for weightlifting that there should be a different kind of shoes. It has been considered in the world of sports that…

together: passing the sting steadily through the hole, making sure it doesn’t come off its axle and that the weight was steady. We repeated this five times then calculated the average of the five trials for each photogate. Continuing, we used the third kinematic equation of one dimensional motion (v22=v12+2aΔx) to calculate the acceleration (working out to be a=v22-v12/2Δx). We chose to use this equation because we only know the speed times, as well as, the difference in distance from photogate…

Cover Page  Warm-Up: The paper presents the concept of the bubble lens which is actually a new targeted acquisition strategy which treats the restrictions associated with the Bubble Cursor in order to boost the speed as well as precision concerning obtaining little; compact targets precisely the targets in which the Bubble Cursor tends to degenerates towards the point cursor. As part of an initial research, we discover the Bubble Cursor carried out inadequately once targets experienced a…

Virginia, Harvard University, and the Italian Olympic Committee, all gave admirations of the practice of running barefoot. The benefits they found were “namely, having foot strikes at the midfoot, less overall impact on the body and better all-body kinematics – while offering caveats about safety, duration and transition from heel-striking to more natural running” (Metzler). Bill Gillford, capitalizes a little more when he tells of his running experiences with Christopher McDougall in his…

2-D VS 3-D Analysis Mechanical work and predicted energy expenditure was also quantified. A secondary purpose was to compare kinematic and kinetic calculations between 2-D and 3-D analyses for both sumo and conventional deadlifts. Two 60-Hz video cameras recorded 12 sumo and 12 conventional style lifters during a national powerlifting championship. Parameters were quantified at barbell liftoff (LO), at the instant the barbell passed the knees (KP), and at lift completion. Unpaired t-tests (P…
