The Signal

2017 General Douglas MacArthur Leadership Award Nomination CPT Seungkyu (Kevin) Kim, Network Operations Technician, HHD 41st Signal Battalion Captain Seungkyu (Kevin) Kim, assistant S3 for the 41st for the 41st Signal Battalion, 1st Signal Brigade, embodies the ideals of Duty, Honor, Country. As the assistant S3 for the most forward-deployed strategic signal battalion in the Republic of Korea, he was responsible for planning strategic communications support to UNC/CFC/USFK/8A and major…

rotates (hence the name). The stator contains electromagnetic coils connected in pairs. There are 3 sections of coils in the motor, each connected to a wire. This is where the ESC comes in to play. It takes the voltage from the PDB, combined with a signal from the flight controller and turns different sections on and off to make the motor spin in different directions. The other kind of motor is a brushed DC motor, also known as a brush motor. It uses two solid brushes to spin the motor. The…

energy stores and signals to the body when it has enough fuel and energy. Researchers concluded that it’s possible that when in the middle of a workout, one’s leptin levels fall, which could send a hunger signal to the brain’s pleasure signal in order to generate the rewarding effects of running. A different study published in the journal Cell Metabolism compared normal mice to genetically engineered mice that lacked STAT3, a leptin-sensitive protein that relays the leptin signal to release…

When you lift a heavy weight (be it yourself or a barbell), your muscles contract. That contraction begins when your nervous system sends a signal to your muscle fibers. When a movement is performed over and over again, and the muscle fibers repeatedly receive an identical signal, a more efficient neuromuscular motor pattern develops. The process by which neurons become more efficient is called myelination. Through regular practice of a movement, a fatty white substance forms a sheath around…

Another symbol that was a good symbol in the beginning of the novel but ends up being evil in the end is the signal fire. The fire symbolizes the hope of being rescued. From the very beginning of the novel, Ralph is very determined to keep the signal fire going in case a ship passes by. “We’ve got to have special people for looking after the fire. Any day there may be a ship out there.”. In this scene it shows how much Ralph wants to be rescued. The fire was a symbol of rescue. The fire starts…

device that receives a stimulus, meaurand, or any input signal such as from heat, pressure, light, motion and many more, and responds with an electrical signal. This electrical signal then will decide what will be the result of an output. Depending on the input of the stimulus, the sensor will react to it in a particular way. Sensors are attached to an electrical device and they scan the surrounding environment. Then it converts the input signals to a voltage, current or charge. This…

Introduction Atrial fibrillation (AF) is the most common heart rhythm disorder. It is an irregular and rapid heart rate caused by heart tissue giving out erratic electrical signals that can increase a person’s risk of stroke, heart failure and other heart-related complications. The risk of AF increases with age with people over the age of 40 having a 25% chance of developing AF. With the increase in aging population in Singapore, there will be higher incidence of AF. Thus there is a need to come…

send and receive signals across the world. Tesla purchased 200 acres from James Warden in 1901, in order to create a wireless telegraphy plant. Tesla then had a 187 foot tall tower built, with a 120 foot foundation in the ground. The tower was made out of timber and steel, with a sphere on top. The tower was supposed to send and receive radio, video, and energy signals from anywhere around the world. Before it could be assured that Tesla was the first one to transmit radio signals, the…

could be worn with rechargeable batteries and circuits can be implanted in the cranium, connected with an array of electrodes inserted in the visual cortex. With this method a blind person was able to vie the flashes of images, when the electrical signals were translated to the visual cortex, though the bulkiness of the device was the major drawback.5 In 1977 Custom resin prosthetic were developed and painted with precision to replicate a normal gaze. This improved the esthetics of the…

The main features of the adaptive immune response is to adapt its response to new invaders and its ability to specifically recognise and remember an invader. B cells are used in the humoral division of the adaptive immune system. Each B cell has a different antigen-binding specificity. Only one B cell is activated per antigen but the activated B cell can differentiate and secrete many antibodies with the same specificity for the original antigen. B cells express specific antigen receptors…
