According the CNN take about the safest airlines, we know that commercial aviation is one of the most heavily monitored industries in the world and statistically the much-cited comparison bears out: you are much less likely to die in an airplane crash than in a car accident. Moreover, in these days, for safety sensitive to the social atmosphere, the safety is the most important ar
1. What are anabolic steroids?
(1) Definition and structure of anabolic steroids
Anabolic steroids - or more precisely, anabolic-androgenic steroids are synthetic derivatives of testosterone.
The effects of anabolic-androgenic steroids mimic those of testosterone. Natually synthesized hormones, such as testosterone, are types of lipids. they have a four-ring carbon skeleton and are synthe
FunctionGenerator)
함수발생기(FunctionGenerator)의 원리를 이해하고, 그 작동법을 익힌다. 또한, 이 과정을 통해 함수 발생기에서 발생한 파의 파형을 관찰하고, 함수 발생기로 다양한 값의 전압을 발생시킨 후 이 발생 전압을 측정한다. (주파수 및 크기 확인)

DC Offset, Voltage, and Timebase values using a functiongenerator and oscilloscope, and compare how each parameter affects the shape of the wave. It was analyzed by dividing it into 5 cases. In the third experiment, the resonance frequency and damping ratio of the RLC circuit were calculated using the Bode Analyzer, and the Gain-Frequency graph and Phase-Frequency graph were derived.
In this project, solutions to second order linear recurrence equations with constant coeffi- cients have been investigated. We have used generating functions to derive the general solution to the homogeneous equation and we show that in general the particular solution is complicated to find. By limiting the right hand side (RHS) in the equation to a polynomial-exponential family of functions we c
