Schematic illustration of production, energy cascade and dissipation in the energy spectrum of turbulence. The largest motions, or eddies, of turbulence contain most of the kinetic energy, whereas the smallest eddies are responsible for the viscous dissipation of turbulence kinetic energy.Kolmogorov hypothesized that when these scales are well separated, the intermediate …

The frequency is obtained from the period, T, which for a harmonic wave equals the zero-crossing period, i.e., the time interval between successive passages of the wave surface through the zero (average) height, in the same direction.The spectral distribution of energy, or energy spectrum when expressed in terms of frequency, F 1 (ν) = 2π F 1 (ω), is usually normalized to the total …

As global population and urbanization rates continue to rise, the energy demand in buildings, particularly for cooling, heating, and power, has surged, constituting over 30% of total energy consumption and contributing significantly to greenhouse gas emissions and environmental degradation (Keskin and Soykan, 2023) response, there is an urgent need for …
Due to the lack of the translational symmetry, calculating the energy spectrum of an incommensurate system has always been a theoretical challenge. Here, we propose a natural approach to generalize the energy band theory to the incommensurate systems without reliance on the commensurate approximation, thus providing a comprehensive energy spectrum theory …

Molecular orbitals of diatomic molecules. We shall consider a specific problem, the neutral (mathrm{H}_{2}) molecule, where electron-electron interaction is also present, and this example explains also why two electrically neutral H atoms tend to form a stable molecule, instead of remaining separated.
The electromagnetic (EM) spectrum spans many types of radiation, from long-wavelength radio waves, through infrared, visible, and ultraviolet "light" and gamma rays and x-rays.
The workflow of this study is shown in figure 1, where we first generate datasets composed of an x-ray spectrum and the corresponding virtual CT image of Gammex phantom, with a specific x-ray spectrum generated by a spectral model using spektr v.3.0. There, sinograms were produced using a material-based forward projection algorithm (MBFPA), and sequential …
To address the challenge of low effective utilization of full-spectrum solar energy by individual technological routes, the spectral splitting (SS) technique emerges as a promising solution.
Energy Spectral Density. The distribution of energy of a signal in the frequency domain is called the energy spectral density (ESD) or energy density (ED) or energy density spectrum. It is denoted by $psi (omega )$ and is given by,

In recent years, hybrid mechanical systems in which a mechanical oscillator is coupled to a microscopic quantum system, such as trapped atoms or ions, solid-state spin qubits, or superconducting devices, have stimulated great interest (see, e.g., [] for a recent review).Typical hybrid mechanical systems include quantum dots [2–4], spin systems [5, 6], …
As illustrated in Fig. 16.1, the physical basis of energy dispersive X-ray spectrometry (EDS) with a semiconductor detector begins with photoelectric absorption of an X-ray photon in the active volume of the semiconductor (Si).The entire energy of the photon is transferred to a bound inner shell atomic electron, which is ejected with kinetic energy equal to …

1 Intrinsic Spatial Resolution. Spatial resolution is a measure of the sharpness and detail of a gamma camera image. Sharp edges or small, pointed objects produce blurred rather than sharply defined images. Part of the blurring arises from collimator characteristics discussed in Sections C and D and part arises in the sodium iodide [NaI(Tl)] detector and …

Region of Fast Neutrons. The first part of the neutron flux spectrum in thermal reactors is the region of fast neutrons.. All neutrons produced by fission are born as fast neutrons with high kinetic energy.. At first, we have to distinguish between fast neutrons and prompt neutrons.The prompt neutrons can sometimes be incorrectly confused with the fast neutrons.

Taking crystal silicon solar cells as an example, the wavelength corresponding to the bandgap of silicon is 1100 nm. As presented in Fig. 1, only solar irradiance with a wavelength less than 1100 nm can be converted into electro-hole pairs by the silicon photovoltaic cells, and the rest of solar irradiance (infrared solar energy, green part in Fig. 1) is absorbed …
