FYFT M-series Unmanned Blimp
FYFT M-series unmanned blimps are Chinese UAVs developed by Qingdao Co., Ltd. Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an M4 series blimp is 11 meter long, then it is named M4-1100, because 11 meter is equal to 1100 millimeter. M-series unmanned blimps are intended for military and para-military use with M stands for Military. The greatest difference between M-series and other unmanned blimps for civilian use such as S-series unmanned blimps for aerial survey is that for military application, data link is added to provide real-time or near real-time transmission of information gathered so troops can respond in a timely manner, as opposed to civilian versions where information is downloaded and evaluated after the UAVs have landed.

FYFT P-Series Unmanned Blimp
FYFT P-series unmanned blimps are Chinese UAVs developed by Qingdao Co., Ltd. Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an A1 series blimp is 11 meter long, then it is named A1-1100, because 11 meter is equal to 1100 millimeter. P-series unmanned blimps are intend for law enforcement applications, and P stands for Police. The greatest difference between P-series and other unmanned blimps for civilian use such as S-series unmanned blimps for aerial survey is that for law enforcement application, data link is added to provide real-time or near real-time transmission of information gathered so police can respond in a timely manner, as opposed to civilian versions where information is downloaded and evaluated after the UAVs have landed.

FYFT S-Series Unmanned Blimp
FYFT S-series unmanned blimps are Chinese UAVs developed by Qingdao Co., Ltd. Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an S1 series blimp is 11 meter long, then it is named S1-1100, because 11 meter is equal to 1100 centimeters. S-series UAV is intended for aerial survey / photography / cinematography, with S stands for Survey.

Gait Analysis in Neurorehabilitation
Gait analysis can be performed through laboratory systems, non-wearable sensors (NWS), and/or wearable sensors (WS). Using these tools, physiotherapists and neurologists have more objective measures of motion function and can plan tailored and specific gait and balance training early to achieve better outcomes and improve patients’ quality of life.

Galileo Probe
The Galileo Probe was an atmospheric-entry probe carried by the main Galileo spacecraft to Jupiter, where it directly entered a hot spot and returned data from the planet. The 339-kilogram (747 lb) probe was built by Hughes Aircraft Company at its El Segundo, California plant, and measured about 1.3 meters (4.3 ft) across. Inside the probe's heat shield, the scientific instruments were protected from extreme heat and pressure during its high-speed journey into the Jovian atmosphere, entering at 47.8 kilometers (29.7 mi) per second. It entered Jupiter on December 7, 1995, 22:04 UTC and stopped functioning at 23:01 UTC, 57 minutes and 36 seconds later.

Gallium Nitride High-Electron-Mobility Transistor
In recent years, GaN-based devices have been widely used in a variety of application fields. GaN-based high-electron-mobility transistors (HEMTs) are superior to conventional silicon (Si) based devices in terms of switching frequency, power rating, thermal capability and efficiency, which are crucial factors to enhance the performances of advanced power converters. This paper addresses some fundamental issues concerning intrinsic features of GaN material and key technology in practical application of GaN-based power switching devices.

Galvanic Anode
A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive electrode potential) than the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure. The loss (or sacrifice) of the anode material gives rise to the alternative name of sacrificial anode.

Game Theory Models to Support Manufacturing Systems
Game theory is a branch of mathematics that studies strategic decision making in situations where multiple agents interact with each other. It provides a framework for analyzing and predicting the behavior of players in competitive and cooperative scenarios. Game theory is a powerful tool for analyzing strategic decision making in various contexts.
