Performance investigation on different form factor embedded heat pipe and pulsating heat pipe heat spreaders

Proceeding of International Heat Transfer Conference 17, 2023
Addressing the thermal management challenge of high-performing power electronics is imperative for standardization. While the performance of a conduction plate heat spreader is limited, passive heat spreading alternatives like Embedded Heat Pipes (EHP ...

Modular Large Array for Liver Cancer Imaging in Handheld Form Factor

IUS, 2021
Hepatocellular carcinoma is difficult to diagnose reliably using ultrasound in patients with thick abdominal walls. An important consideration for improving diagnosis in these patients is increased contrast to noise resolution (CNR) which is directly ...

The Smallest Form Factor Monopole Antenna with Meandered Radiator for WLAN and WiMAX Applications

Journal of the Institution of Electronics and Telecommunication Engineers, 2020
The demand for designing antennas having multiband operations along with very compact dimensions is increased recently. Compact and low-profile antennas are required which can be used with multiple communication standards in a portable device.

Passenger detection in cars with small form-factor IR sensors (Grid-eye)

Electronics System-integration Technology Conference, 2020
In this paper, an experiment of passenger detection in cars is presented. A small and cost-effective, commercial IR sensor was used to investigate the possibility of detecting people in the different seats of the car.

On the dynamic form factor of an electron liquid

Solid State Communications, 1974
Abstract The mean field theories of an electron liquid at metallic densities, which go beyond the RPA, and which have been fairly successful so far, are shown to be inadequate when tested against phenomena involving high frequencies. It is also shown that by making a simple Gaussian ansatz for the imaginery part of the response function, χ″(q,ω), and

Electron form factors of deformable nuclei

Soviet Physics Journal, 1987
Using the smallness of the deformation parameter of the nucleus, we obtain simple explicit expressions for the form factors of electroexcitation of the low-lying rotation-vibration states of light, deformable, even-even nuclei. The expressions satisfactorily describe the experimental data on the excitation of collective nuclear states by the inelastic ...

Magnetic form factor for itinerant-electron systems

Physical Review B, 1994
First-principles calculations of the itinerant-electron magnetic form factor for ferromagnets which include both the spin and orbital contributions have been completed for ferromagnetic nickel and iron. To our knowledge, these are the first calculations of this type for 3[ital d] ferromagnets.

Absorptive form factors for high-energy electron diffraction [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 1990
The thermal diffuse scattering contribution to the absorptive potential in high-energy electron diffraction is calculated in the form of an absorptive contribution to the atomic form factor. To do this, the Einstein model of lattice vibrations is used, with isotropic Debye-Waller factors.

Electron-scattering form factors for the giant dipole resonance [PDF]

Journal of Physics G: Nuclear and Particle Physics, 1995
Using a previously developed formalism based on the generator coordinate method, the longitudinal- and transverse-excitation form factors for the giant dipole resonance are obtained. Although microscopically established, that approach can provide analytic and compact expressions for some selected closed-shell nuclei.
