Data processing techniques for ion and electron-energy distribution functions

Discharge Cathode Electron Energy Distribution Functions in a 40-cm NEXT-type Ion Engine*

Electron energy distribution functions (EEDF’s) are presented over a two-dimensional array of locations in the discharge chamber of a 40-cm diameter ring-cusp ion thruster. The EEDF’s are obtained using two different techniques illustrating comparable results. A distinct difference in the EEDF’s measured through the double layer potential gradient, which transitions between the low-potential di...

Parton distribution functions at the Electron-Ion Collider1

High-statistics deep-inelastic scattering at the EIC can elucidate several open questions about the structure of nucleons and nuclei that cannot be answered solely by measurements at the Large Hadron Collider. These questions include avor composition of PDFs; nuclear correction factors; e ect of isospin violation on the PDFs; and behavior of the longitudinal structure function FL at the boundar...

Data processing for atomic resolution electron energy loss spectroscopy.

The high beam current and subangstrom resolution of aberration-corrected scanning transmission electron microscopes has enabled electron energy loss spectroscopy (EELS) mapping with atomic resolution. These spectral maps are often dose limited and spatially oversampled, leading to low counts/channel and are thus highly sensitive to errors in background estimation. However, by taking advantage o...

با توجه به گسترش روز افزون تقلب در حوزه بیمه به خصوص در بخش بیمه اتومبیل و تبعات منفی آن برای شرکت های بیمه، به کارگیری روش های مناسب و کارآمد به منظور شناسایی و کشف تقلب در این حوزه امری ضروری است. درک الگوی موجود در داده های مربوط به مطالبات گزارش شده گذشته می تواند در کشف واقعی یا غیرواقعی بودن ادعای خسارت، مفید باشد. یکی از متداول ترین و پرکاربردترین راه های کشف الگوی داده ها استفاده از ر...
