The Distributional Stress-Energy Quadrupole [PDF]

, 2020
We investigate stress-energy tensors constructed from the delta function on a worldline. We concentrate on the quadrupole which has up to two partial or derivatives of the delta function.

Circular Geodesics in a New Generalization of q-Metric

Universe, 2022
This paper introduces an alternative generalization of the static solution with quadrupole moment, the q-metric, that describes a deformed compact object in the presence of the external fields characterized by multipole moments.

RF and Surface Properties of Superconducting Samples [PDF]

, 2011
The surface resistance Rs of superconducting cavities can be obtained from the unloaded quality factor Q0. Since Rs varies strongly over the cavity surface its value must be interpreted as averaged over the whole cavity surface.

Optimization of Ultrafast Proteomics Using an LC-Quadrupole-Orbitrap Mass Spectrometer with Data-Independent Acquisition

, 2022
Proteomics has become an increasingly important tool in medical and medicinal applications. It is necessary to improve the analytical throughput for these applications, particularly in large-scale drug screening to enable measurement of a large number of

MODEL OF THE FLAT FAIRING ANTENNA DIELECTRIC LAYER WITH AERODYNAMIC HEATING

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2023
To protect the antenna systems of modern aircraft, radio-transparent dielectric fairings are widely used. At low flight speeds, when designing and evaluating the characteristics of the fairing-antenna, it is assumed that the dielectric constant is a ...

Compact, Broadband, and Omnidirectional Antenna Array for Millimeter-Wave Communication Systems

Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021
In this paper, a millimeter-wave printed quadrupole antenna is proposed. It consists of two symmetric printed dipoles that make the quadrupole radiating power omnidirectionally.

Thermal quadrupole method with internal heat sources [PDF]

, 2012
A new method based on the thermal quadrupoles technique for heat transfer modelling in multilayered slabs with heat sources is proposed. Classical thermal quadrupoles use hyperbolic functions and numerical problems occur according to the argument value ...
