Fermi Level Dynamics01:12

Fermi Level Dynamics

735
The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Incomplete Dominance01:43

Incomplete Dominance

30.0K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Reliability and Validity

14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Levels of Communication II: Organizational, Public, and Group Dynamics

3.0K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

What is Energy?04:10

What is Energy?

59.2K
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

52.1K
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...

Área de la Ciencia:

  • Ingeniería de Sistemas de Energía
  • Ingeniería de Fiabilidad
  • Ciencias Ambientales

Sus antecedentes:

  • Los sistemas de energía integrados a nivel de parque (PIES) implican interacciones dinámicas complejas y multiescala entre subsistemas de electricidad, gas, térmica y de edificios.
  • Las evaluaciones de fiabilidad existentes a menudo pasan por alto las respuestas transitorias críticas y los impactos a largo plazo en la salud humana de las interrupciones del suministro de calor.

Objetivo del estudio:

  • Desarrollar un método novedoso de evaluación de fiabilidad para PIES que incorpore la dinámica transitoria y las consideraciones de salud humana.
  • Abordar las limitaciones de los métodos actuales incluyendo los impactos de escenarios extremos como las interrupciones del suministro de calor.

Principales métodos:

  • Se utilizó la simulación cuasi-estacionaria para modelar los comportamientos dinámicos de los sistemas de electricidad, gas, calefacción y edificios.
  • Se desarrollaron modelos simplificados cuasi-estacionarios para la demanda de energía y la evolución de la temperatura interior en condiciones extremas.
  • Se formuló un nuevo índice de fiabilidad que considera la inercia térmica de la red de calefacción urbana y la tolerancia a la temperatura de los ocupantes.

Principales resultados:

  • El método propuesto mejora la precisión y la interpretabilidad de las evaluaciones de fiabilidad de PIES.
  • Se tendió con éxito el puente en la evaluación de los impactos en la salud de los usuarios durante eventos extremos.
  • Se confirmó que la dinámica térmica de los edificios influye significativamente en la fiabilidad general de PIES.

Conclusiones:

  • El método de simulación cuasi-estacionaria proporciona un marco integral para la evaluación de la fiabilidad de PIES.
  • La incorporación de la salud de los ocupantes y la inercia térmica de los edificios conduce a evaluaciones de fiabilidad más realistas.
  • Las características térmicas de los edificios son un factor crítico para garantizar la fiabilidad de PIES, especialmente en condiciones adversas.
