Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.
The Lockheed P-80 Shooting Star is the first jet fighter used operationally by the United States Army Air Forces (USAAF) during World War II. [1] Designed and built by Lockheed in 1943 and delivered just 143 days from the start of design, two pre-production models saw limited service in Italy just before the end of World War II.
The RF-80's were responsible for the daylight operations; the RB-26s for night photography. In June 1952, the 117th was involved in Exercise 'June Primer'. This exercise took place in an area bordered by a line drawn from Cherbourg to Geneva in the east and in the west by the Swiss, Austrian and Russian occupation zone borders.
Motion capture of two pianists' right hands playing the same piece (slow-motion, no-sounds) [1] Two repetitions of a walking sequence recorded using motion capture [2]. Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people.
Interactive Scenario Builder (Builder) is a modeling and simulation, three-dimensional application developed by the Advanced Tactical Environmental Simulation Team (ATEST) at the Naval Research Laboratory (NRL) that aids in understanding radio frequency (RF) and electro-optical/infrared (EO/IR) propagation.
An RF enclosure or a cage that goes around the electrodes and open areas is used to protect the operator from injury including radio frequency radiation. [1] Automated machines can be semi-automatic (requiring the operator to manipulate the parts) or fully automatic (where the machine is responsible for loading, transporting, and manipulating ...
Some omnidirectional cameras contain wide-angle lenses on the front and rear to facilitate the recording of 360-degree video. 360-degree video is typically recorded using either a special rig of multiple cameras, or using a dedicated camera that contains multiple camera lenses embedded into the device, and recording overlapping angles simultaneously.
The rule also applies to the movement of a character as the "line" created by the path of the character. For example, if a character is walking in a leftward direction and is to be picked up by another camera, the character must exit the first shot on frame left and enter the next shot frame right. A jump cut can be utilized to denote time. If ...
