Sine wave

photosensors, and a glass scale. The light source in conjunction with a lens creates a beam of light, which passes through a scanning reticle and then through the glass scale. That light is then picked up by photosensors, which creates a type of sine wave output, which the linear encoder interprets (Figure 5, Anaheim Automation, 2016). The level of accuracy created in this system is very high but the glass scale and…

For Hume, the idea of “reason” refers to inductive reasoning, or the ability to make associations between different things, and to recognize cause and effect. He argues that animals learn things two ways: from observation, and from instinct (Hume, pg. 71,72). Both of his ideas are persuasive, especially when looking at the behavior of chimpanzees and their use of tools. However, his argument that animals learn based on experience or observation is slightly more persuasive than his argument that…

From simple agricultural civilizations to large and advanced empires, the Classical Period, from 1000 B.C.E. to 500 C.E., was one of the most important and developmental periods in human history. During this period, several large civilizations developed in the Middle East and Asia. These civilizations made many advancements in areas such as politics, economy, technology, art, and religion. Two major civilizations that developed during the classical period were China and the Indian subcontinent.…

Morse first noticed it on the transatlantic telegraph cables transmitting messages using dots and dashes and it has not gone way since. He handled it by just slowing down the transmission. Amplitude Time Figure 8 101101 transmitted data Figure 8 shows a data sequence, 1,0,1,1,0, which wish to be sent. This sequence is in form of square pulses. Square pulses are nice as an abstraction…

Solar Energy has been in use for the last one hundred years and through its existence, it has been a technology that has been constantly and consistently updated to maximize its usage. In the present day, where the want to reduce our dependency on fossil fuels is greater than ever, solar power is becoming a more attractive alternative for people all over the world. While solar power is only responsible for a small amount of the energy created in the United States, it has been on the rise in…

91. How One Finds Humility & Courage TO FORGIVE? • Christ suggested that we must not be ever tired of FORGIVING. Many wonder if that ‘path’ is correct one. Modern Intellectual cannot accept anything at face value. Everything requires logical explanation, which is compatible with ‘Cosmic’ or ‘Natural Laws’. The ‘Reasons’, ‘Why ALWAYS to FORGIVE’ are not exemption. • First major step in right direction is to raise above ‘local’ logic. The ‘local’ logic insists that if someone did the ‘evil’ must…

When I am about to drive home after my shift, I examine my face in the rear-view mirror. If I only knew how to change, to make me a protagonist again. Looking the part would at least be a starting point. I shrug, and start the motor. One day it will be too late, but not like Jan or Tessa think when they urge me to finish school, and apply to university to read a rational subject, because my ‘too late’ takes place far beyond that. Too late means to know what life is about, to have made all…

Give Us Medical Autonomy or Give Us Death… As teenagers we cannot wait to grow up, to be able to make all those “adult” choices and finally be able to do what you want. My generation and future generations are becoming more and more eager to “grow up” and have autonomy that it might actually have us miss out on key lessons of growing up; but one area that that we are not be able to grow into is the medical world. An article from The Health Affairs shows that medical issues are increasing more…

This rib is also suitable for a variety of loading conditions. Forged ribs are manufactured using heavy press-machinery, and are used for sections where very high loads apply. Milled ribs are solid structures, manufactured by milling away excess material from a solid block of metal, and are also used where very high loads apply. The stringers on the skin panels run in the length of the wing, and so usually need to bridge the ribs. There are several methods for dealing with this problem. The…
