array in which the amplitudes of theantenna elements in the array are arranged according to thecoefficients of the binomial series. 20.What are the advantages of binomial array? Advantage: • No minor lobes Disadvantages: • Increased beam width • Maintaining the large ratio of current amplitude in large arrays is difficult 21. What is the difference between isotropic and nonisotropicsource Isotropic source radiates energy in alldirections but non-isotropic source radiates energy only

of propulsion from episode to episode. One example is the famous tractor beam, used by the Enterprise to capture and manipulate objects or other spacecraft outside of the ship. When solely looking at the

designed to have single load bearing rods that would pass through the fourth floor walkways supporting beams, be supported with nuts and washers and hang the second floor walkway beneath as shown in the “Original Detail” in figure 1 . Due to a late design change for apparent manufacturing issues, the change was quickly implemented to the “As Built” design shown in Figure 1.

Abstract Coherent diffraction imaging (CDI) is a type of microscopy that forms an image of an object from its diffraction pattern. At long distances, the Fraunhofer equation gives the intensities of the diffraction pattern as the complex modulus of the Fourier transform of the object’s true image.1 each spatial frequency in reciprocal space are lost, so the object’s image cannot be perfectly reconstructed. Knowing the dimensions of the object allows us to place constraints on the image so

Unfortunately, the jet fuel compromised the buildings structure by weakening the beams and ultimately contributed to the overall death toll on 9/11. The Twin Towers webbed trusses had not undergone any type of fireproof testing prior to 9/11. “Two of the world's tallest buildings have never undergone a trial by fire”. (page 69)

pass of its magnitude (Beam, 2009). The bill contained a wide variety of public health issue as well as covering every type of health coverage for the elderly and disable. “Advocate of Medicare was careful not to paint the plan as a stepping stone on the way to government-run health care—but they formulated their plan in a way that could logically be expanded to cover everyone. That meant picking a group that everyone agreed should be covered in full: senior citizens,” (Beam, 2009). “Few politicians

The first working laser was created by Theodore Maiman, who placed a ruby rod, a fully reflective mirror on one end, a partially reflective mirror on the other, with a high-intensity lamp wrapped around the ruby rod into a cylinder to create a laser beam. When the lamp was turned on, it excited the electrons in the ruby rod. Excited electrons emitted photons,

Massive. Brave. Strong. Tall. These words all describe Maxwell Kane. Maxwell Kane is a thirteen year old boy that is a big guy with an even bigger heart. He might not be the bravest person in the world, but Maxwell Kane is braver than he believes. Maxwell Kane is braver than he believes in multiple different ways. For instances, when he gets a note from Worm, his friend Rachel, he takes it and finds her. He saves her from her abusive father by breaking down a door. “But the rest of me is thinking

radiation that passes through the body, recording an image on photographic film or a special detector; various parts of the body absorb the X-rays in varying degrees” (Chest X-ray, 2016). Depending on how dense the structure impeding the flow of the beam is; X-rays are absorbed by the denser structures and not reach the film, presenting with the whitened markings; moreover, X-rays can penetrate thinner structure and reach the film, presenting with darkness. The varying degrees of absorption are represented
