Summary
We propose femto-cloud and Floating Fog to enhance aerial internet connectivity and enable complex onboard services by aggregating passenger devices and utilizing ship-based resources. This improves internet access for flights over water.
Area of Science:
- Computer Science
- Networking
- Wireless Communication
Background:
- Millions of passengers fly daily with multiple internet-connected devices, often idle during flights.
- Onboard devices lack resources for complex services like machine learning or AR/VR.
- Current satellite internet for flights is unreliable and slow.
Purpose of the Study:
- To present the utility of femto-cloud for aggregating onboard devices for aerial users.
- To propose an adaptive beamforming solution for reliable aerial internet provisioning.
- To introduce Floating Fog, an extension of fog computing for maritime environments, to support delay-sensitive and resource-intensive services.
Main Methods:
- Utilizing idle onboard devices for multi-device resource aggregation (femto-cloud).
- Developing adaptive beamforming techniques for enhanced aerial internet connectivity.
- Extending fog computing to ships at sea (Floating Fog) with beamforming transceivers.
Main Results:

01:11Buoyancy and Stability for Submerged and Floating Bodies
2.1K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

When an object is placed in a fluid, it either floats or sinks. All objects in a fluid experience a buoyant force. For example, a metal ball sinks, while a rubber ball floats. Similarly, a submarine can sink and float by adjusting its buoyancy. The concept of buoyancy raises several interesting questions. For instance, where does this buoyant force come from? How much buoyant force is required to make an object sink or float? Do objects that sink get any support at all from the...

When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

01:18Boundary Layer Characteristics
241
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...
