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…

depended on conductivity variation inside the material [1, 45, 46]. Furthermore, according to equations 3.5 and 3.6, space charge can be accumulated in insulation material in steady state condition due to the variation of permittivity to conductivity. As a result, by combining equation 3.2, 3.3 and 3.6, the equation of determining space charge in steady state condition can be written ∇.(ε_0 ε_r E)=∇.(ε_0 ε_r J/σ)=J.∇((ε_0 ε_r)/σ)+ (ε_0 ε_r)/σ ∇.J=J.∇ ((ε_0 ε_r)/σ)= ρ (3.7) …

Personal Philosophy After completing the leadership inventory, I came to find that I had equal amounts of each of the four leadership styles. Personally, I thought my primary leadership style was analytical and my secondary leadership style was supportive. I did not see myself as being directive or adaptive, so I was surprised at the results. By having equal amounts of all four leadership styles, I will be able to use all the different characteristics of these leadership styles to aid in my…

American Overture for Band is a level six, wind band, piece that has been played and enjoyed by advanced high school and university bands. The scoring is dense and somewhat atypical, however. Jenkins includes a sting bass, a cello, three baritone parts, three flute parts, and four clarinet and trombone parts. Jenkins includes the string bass part because is important to the texture of the piece. The tuba cues, like all the cues in the piece, are “safety doublings” and “should be played only…

CHAPTER TWO - CRITICAL ANALYSIS 2.1 Exploration Of Tonality And The Pentatonic Scale Blossoms on a Moonlit River has been written in G major, and this is known from an author’s note written above the stave and the key signature (Fig 2a). It has been written with diatonic numerical notation using the numbers 1 to 7, and the number 0 represents a rest. The piece is tonal centred, and relies on a major pentatonic scale consisting of G, A, B, D and E (Fig 2b) and this is close to the western…

For this paper, I listened the RadioLab episode on music language. I chose this one because, being a musician myself, I’ve always been interested in the psychology behind music, specifically why certain sounds can so drastically alter our emotion. After all, they’re all just vibrations. So what is it about some vibrations that make them so much more significant to us than others? This is one of the primary questions addressed in this podcast. In discussing how music affects us emotionally, the…
