Distribution and Dispersion00:54

Distribution and Dispersion

22.6K
To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

Cable Subjected to a Distributed Load

842
The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.

Viral Structure00:56

Viral Structure

66.5K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Transformers in Distribution System

180
Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Uniform Depth Channel Flow01:27

Uniform Depth Channel Flow

199
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...

Secondary Distribution01:25

Secondary Distribution

159
Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Area of Science:

  • Computer Science
  • Networking
  • Mobile Computing

Background:

  • Mobile multimedia services are increasingly important for high-quality video streaming.
  • Vehicular ad-hoc networks (VANETs) require robust video streaming for safety and infotainment.
  • High vehicle mobility poses significant challenges to seamless video packet distribution and quality of service (QoS)/quality of experience (QoE).

Purpose of the Study:

  • To address the limitations of existing schemes in supporting mobile video streaming in VANETs.
  • To propose a novel video packet distribution scheme for enhanced QoS and QoE in VANETs.
  • To improve data caching and seamless packet forwarding for real-time video services.

Main Methods:

  • Introduced the 'Clone' scheme integrating vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications.
  • Defined 'current network quality information' (CNQI) to assess node data forwarding capabilities (delivery ratio, delay).
  • Selected access points ('clones') based on CNQI and vehicle trajectory for caching; optimized packet distribution and synchronized data delivery.

Main Results:

  • The proposed Clone scheme effectively disseminates video packets for streaming services in VANETs.
  • Experimental results demonstrate superior performance in terms of QoS and QoE compared to existing methods.
  • The scheme successfully addresses challenges related to vehicle mobility and ensures continuous video packet distribution.

Conclusions:

  • The Clone scheme provides a viable solution for high-quality video streaming in VANETs.
  • Integration of V2V and V2I communication, along with intelligent caching, significantly enhances streaming performance.
  • The approach offers a promising direction for improving infotainment and safety applications in connected vehicles.
