at central wavelength ~790nm, and τFWHM pulse duration is ~ 22 fs (in intensity) at 1mJ., in a gas filled hollow core fiber (HCF). Hence, these pulses are focused by a bi-convex lens (f=1.8 m) into the hollow core fiber entrance. The beam size at the focus is ~ 200 µm. The converging beam enters the HCF apparatus chamber, which is schematically illustrated in Figure 3a, through a ~0.5mm fused silica (anti-reflection coated) entrance window mounted in far distance (~80 cm) to reduce the self-phase modulation. The Ne gas pressure has been adjusted inside the chamber to ~2.2bar, in order to yield the broadest spectra. This broadband spectrum exits the capillary through a thin (~0.5 mm) UV-grade fused silica window, which is mounted at Brewster’s angle of ~790 nm at the end of the HCF`s chamber, in order to provide efficient transmission over a broad spectral…
In the article, The Role of Definition, the author discusses how a mere definition can affect the way a student will interpret information. A definition can contain concepts that are difficult to understand and will hamper a student’s ability to learn. As math in the classroom progresses, The National Council of Teachers of Mathematics recommends that the students create their own definitions of for mathematical terminology with the modification from a teacher. This is done to get the student to…
“Geometries in Cold Welded Steel.” This artwork was presented by the artist Tom Duchscher. Duchscher has been teaching design, sculpture, and ceramics at MJC for the past 40 years. His work has been exhibited throughout northern California and pacific northwest. For the past four decades Duchscher has dealt with the exploration of geometric forms and has focused on the element of line. This has allowed him to create illusionary and actual phenomenon. The use of linear parallel in his artwork has…
This can be seen when the different races speak straight into the camera about they hate other races. It can also be seen when Lee himself looks into the camera and says, “You’re all racists”. Lee also uses different lighting to expose the extreme heat that the characters are faced with. Overall, Lee produced his film by exploiting pre and post classical Hollywood cinema techniques by using music and facing the camera on the characters in different angles and using close up shots. Having…
drive and pull out a few feet if this happens. Now your car is at an angle, so let the car reverse in a staright line. You should be looking over your right shoulder. You can have one hand on the 12 mark of the steering wheel and the other hand on the passenger seat. Turn the wheel quickly to the left with two hands. If you don’t turn the wheel all the way to the left, you might end up getting to close to the curb or hitting it. You can check this by looking at your side-view mirror, if it looks…
because reflective markers were added on the bony landmarks of their hip (greater trochanter) knee (lateral epicondyle) ankle (lateral malleolus) and toe (5th metatarsal). Trials runs were given to the participants before the testing, to familiarize with the experiment. Additional time measures were noted of every trial and divided it by the distance (4.5 m) in order to calculate the speed in meters per second (m/s). Experimental Protocols: For the Motion analysis system, the QualisysOgus 3+…
isosceles triangle the base angles are congruent , so that means that angle Q is equal to angle P, since angle Q is 45 degrees, angle P is also 45, and because a triangle has 180 degrees, the remaining angle(O1) must be 90 degrees. This proves that the triangle PO1Q, is a right triangle, and…
figure 2, the blue lines represent the two shapes of the building. The orange represent the overall area that we can work to remodel in. The green lines represent the sidewalks that will connect both buildings. The bottom blue shape has four sides, the top and bottom side are parallel to each other and so are the side sides. The side sides are also congruent. Now since there is four sides in the shape, that means all 4 interior angle equal to 360 degrees. Each angle in the shape is equal to 90…
In this lab we will explain how to deduce the equation landing position of the ball thrown by the robotic arm stand. We must create the equations in terms of the radius, height, arm rotation speed, and release angle. The equations must be made with those variables because, those variables are what can change where the ball will land in the cup, and will make the equation more useful to the client. To make sure the equation will remain accurate we have to keep track of all the units throughout…
how large and almost powerful nature was around them. He did this in a couple ways. One way is the tree to the right of them is drawn closely to them. By doing so it shows just tall and magnificent this tree is compared to the sixe of the horse, the boy, and the man. Another made nature seem large and powerful is by having the mountain range in the background. You have the tree close to them to show one example of how large nature is and then in the distance with almost no detail you have a…
