  • Fabrication Lab Report

    Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards. Printed circuit boards can be used for just about anything from power dividers to filters. Ring resonators are used to find microwave substrates produced in the ring resonators and can be antennas to circuit boards. The FR4 Ring Resonator is used for…

  • Maxwell And Faraday Research Paper

    Maxwell and Faraday- A Brief History of Electromagnetism The field of electromagnetism was established in 1819, twelve years before Maxwell was born. Hans Christian Oersted from Denmark was the first scientist who thought of the possibility that magnetism and electricity were related. He considered such a possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when…

  • Adaptive Therapy Case Study

    allowed to test the geometrical accuracy of the system on real patients. The vertebra is easily visualized on the integrated megavoltage imaging system and allows for accurate comparison of field co-ordinates with MRI co-ordinates. The system was accepting patients since around 2012. (Ref 4). The individual MRI-Linac procedures were very reproducible, on average taking 41 min (range 33–44 min) and were well tolerated by the patients. This excludes approximately 15 min of bringing…

  • Separation Technology Essay

    10754BPhotoelectric separation technology is a method to separate different materials according to the characteristic of the light reflection of material surface and has been used to separate glass of different colours. The colorless glass and colored glass contained in the waste glass should be separated according to various colors. Electric separation is a method using different electrical properties of components in high voltage electric field to separate wastes. This technology is mainly…

  • Pros And Cons Of Potential Energy

    Energy is the ability to work, more, or elicit change in matter. Energy cannot be formed or impaired; it’s always preserved. Potential energy is a kind of spared energy that objects have because of their position or configuration. Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to…

  • Sharon Begley Mapping The Mind Analysis

    With this information, the volunteers’ amygdalae lit up. The neuroscientists were able to predict that a volunteer would feel a nonexistent electric shock by “reading their mind” and mapping the brain (Begley 1992). In order to complete the functional map of the brain, technologies and devices were invented with the purpose of extending neuroscientists’ knowledge of the brain. Mapping the Brain not only emphasizes on how the brain is similar to a map with its different regions, but also on how…

  • The Importance Of Mathematical Predictionss For Hydrogen

    – equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…

  • Electromagnetic Waves Vs Mechanical Waves

    Waves are disturbances that transfer energy from one place to another without transferring the particles of a medium. Some waves must travel through matter, known as the medium (mechanical waves). And when they travel through the medium they cause the particles to vibrate. Some types of mechanical waves are sound waves and ocean waves. Electromagnetic waves, on the other hand, are waves that do not need to travel through a medium. They are disturbances in both the electric and magnetic fields.…

  • High Energy Electron Reflection Essay

    correlation of surface coverage of 2-D clusters with idealized RHEED oscillations. (Adapted from J.R. Arthur, Surface science 500 (2002) 189-217) There are similar in situ surface studies techniques used by means of optics, such as reflectance difference spectroscopy (RDS), which also known as reflectance anisotropy (RAS). This technique measures the difference in reflectance between two orthogonal polarization states of light falling at near-normal incidence on the sample surface[8]. The…

  • Argumentative Essay On Alternative Energy

    “Wind turbines turn in moving air and power an electric generator that supplies an electric current. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.” (Wind Energy Basics) Two advantages of wind energy are no matter how much is used today the same amount will be around in the future, and it is a clean form of energy that won’t pollute the earth. Two disadvantages are the cost to create it is high and it creates some noise that could be a…
