Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

What is Energy?04:10

What is Energy?

58.9K
The universe is composed of matter in different forms, and all forms of matter contain energy.  The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free Energy01:21

Free Energy

52.0K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Free Energy Changes for Nonstandard States

13.6K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

Área de la Ciencia:

  • Ciencias de la Computación
  • Ingeniería de Redes
  • Comunicación Inalámbrica

Sus antecedentes:

  • La eficiencia energética es un desafío importante en las Redes de Sensores Inalámbricos (WSN), especialmente con el tráfico de red fluctuante.
  • Los protocolos existentes como S-MAC y T-MAC tienen limitaciones debido a ciclos de suspensión fijos y problemas de suspensión temprana, lo que dificulta la adaptabilidad.

Objetivo del estudio:

  • Introducir un novedoso protocolo MAC de ciclo de trabajo de suspensión (SD-MAC) para WSN.
  • Ajustar dinámicamente los períodos de escucha activa en función del tráfico de red en tiempo real para reducir la escucha inactiva y mejorar la utilización de la energía.
  • Mejorar el rendimiento general de la red, incluido el ahorro de energía, el rendimiento y la fiabilidad.

Principales métodos:

  • Desarrolló el protocolo SD-MAC con un mecanismo de programación consciente del tráfico con ciclos de trabajo sintonizables.
  • Realizó simulaciones exhaustivas utilizando el simulador de red NS-2.
  • Evaluó métricas de rendimiento que incluyen el consumo de energía, el retraso de acceso al medio y la tasa de entrega de paquetes en diversos escenarios de tráfico.

Principales resultados:

  • SD-MAC logró hasta un 10% más de ahorro de energía en comparación con T-MAC.
  • Demostró un mayor rendimiento que T-MAC.
  • Superó a varios protocolos MAC recientes en consumo de energía, retraso de acceso al medio y tasa de entrega de paquetes.

Conclusiones:

  • SD-MAC mejora eficazmente la eficiencia energética y la escalabilidad en las Redes de Sensores Inalámbricos.
  • El ajuste dinámico del ciclo de trabajo del protocolo resulta beneficioso, especialmente en entornos de tráfico bajo a medio.
  • SD-MAC ofrece una solución fiable para aplicaciones WSN con restricciones de energía.
