Let a_0 = 0. Using equations 2 and 3, after canceling terms, ∫_"0" ^"T" ▒〖"f" ("x" )" " "sin" ⁡〖"πkx" /"T" 〗 " dx= " 〗 "b" _"k" "T" "b" _"k" "= " "1" /"T" ∫_"0" ^"T" ▒〖"f" ("x" ) "sin" ⁡〖"(" "πkx" ⁄"T" ")" 〗 "dx" 〗 The process to derive "a" _"k" was much simpler than deriving "b" _"k" , since I simply multiplied the original equation by "cos" ⁡〖"πmx" /"T" 〗 and then used the orthogonality conditions. "f" ("x" )"=" "a" _"0" "+" ∑_"k=1" ^"∞" ▒("a" _"k" "cos" ⁡〖"πkx" /"T" 〗 "+" "b" _"k"

Menu, select Open Activity and open the file simple harmonic motion. [The files are located inside “My documents”, “Mechanics”]. Calibrate the Sensor In this part, only the motion sensor is acquiring data. The force sensor functions solely to provide a means to suspend the spring and mass. With the spring-mass system stationary, select Start. Data will be taken for 5 seconds, then stop automatically. The graph is displayed in the Simple Harmonic Motion graph window should not have large spikes.

and due to these loads power quality is being deteriorated. The supply voltage is distorted due to harmonic currents drawn from the supply by nonlinear loads. Distorted currents and voltage cause the user’s equipment to not work properly, conductors will overheat and may decrease the efficiency and life of the equipment. Usually a passive LC power filter is employed to wipe out the current harmonics

musical devices that the composers use are similar, the way they use these musical devices are completely different. I would argue that Schubert and Schoenberg bring the text to life through the accompaniment, through the voice, and through their harmonic structure in their own unique ways. In “The Elf King” by Schubert,

on the final note). At the time, these intervals dominated the harmonic and melodic structures because of the musicians’ natural ability

Viennese composer Franz Schubert is often regarded as a master composer of songs. He is also known for creative and unexpected movement between keys in his compositions. Dying at a tragically young age, Schubert managed to release an enormous body of works, publishing over two-hundred songs while alive. Despite this already impressive output of songs, nothing stopped Schubert from composing symphonies, chamber music, and solo works as well. Close analysis of his music reveals how skillfully Schubert

be a higher note. Closed-end air can be many things; ranging from brass instruments, woodwind instruments, organ pipes, and flutes. These closed-end air columns cannot produce an even harmonic. It has a 1st harmonic, 3rd harmonic, and fifth harmonic. These harmonics are can be understood as, the 2nd harmonic being twice that of the 1st, and the 4th being four times that of the 1st . Sound is a wave, and a wave can be remembered as a medium, carrying energy from one point to another. The sound

ii. Experiment 7 The first part of this experiment involved calculating the wave speed of traveling waves on a string that was bounded on both sides (i.e. one side bounded by a clamp, and the other by a pulley) for three different tensions being applied. The wave speed was calculated using two different methods: 1. By calculating the tension that was being applied to the string, T=(m_1+m_2 )g, where m_1 is the mass of the hanging weight, and m_2 is the mass of the portion of the string hanging

increase in distributed generation especially PV resources in the grid, this paper puts up a discussion on impacts of high PV penetration level on distribution grid. High penetration of PV can cause problems such as reverse power flow, voltage rise, harmonics etc. This paper also discusses potential measures to mitigate these problems. Keywords – Distributed generation (DG), photovoltaics (PV), distribution network I. INTRODUCTION Due to growing environmental concerns, adoption of policies favoring renewables

Modren HVDC systems are having many advantages than HVAC sytems. Two AC systems are connected using a new VSC-MMC based Hybrid HVDC system in this paper which gives many advantages than the conventional HVDC systems and LCC-VSC Hybrid systems. The proposed system gives the fast dynamic response by using different control stratagies. The active and reactive power is controlled and the dc line voltage is maintained constant at inverter station. Under steady state and transient conditions the system
