Dynamic RCS Simulation Using Active Frequency Selective Surface

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper introduces a target RCS simulation method based on active frequency selective surface (AFSS) echo power modulation, which is both cost‐effective and real‐time. By employing the AFSS echo power modulation model, we define the RCS parameters for the AFSS reflector and establish the theoretical relationship between modulation parameters and RCS

Three Decades of Coronary Artery Bypass Grafting in Octogenarians: Clinical Outcomes and Long‐Term Survival

Journal of Cardiac Surgery, Volume 2025, Issue 1, 2025.
Background Despite the rapid growth of the elderly patients presenting for coronary artery bypass grafting (CABG), long‐term outcomes for patients over 80 years of age are incompletely understood. We set out to investigate clinical outcomes and long‐term survival for octogenarian CABG patients across 3 decades.

Localization of Jet Engine Position from HRRP-JEM Images of Aircraft Targets Using Eccentricity of Complex-Valued Signals [PDF]

, 2013
2005년에 처음 소개된 HRRP-JEM(High Resolution Range Profile-Jet Engine Modulation) 영상은 항공기 표적에 탑재된 제트 엔진의 장착 위치를 추정함으로써 레이더 표적 인식을 수행한다. 본 논문에서는 복소 신호의 이심률을 기반으로 HRRP-JEM 영상에서 제트 엔진 위치를 추정하기 위한 새로운 접근법을 제시한다. 복소 신호의 이심률은 HRRP-JEM 영상을 구성하는 어떤 거리 성분(range bin)에서의

Radar HRRP Target Recognition Based on Stacked Autoencoder and Extreme Learning Machine [PDF]

, 2018
A novel radar high-resolution range profile (HRRP) target recognition method based on a stacked autoencoder (SAE) and extreme learning machine (ELM) is presented in this paper. As a key component of deep structure, the SAE does not only learn features by

Point-HRRP-Net: A Deep Fusion Framework via Bi-Directional Cross-Attention for Space Object Classification Using HRRP and Point Cloud

Remote Sensing
High-Resolution Range Profile (HRRP)-based space object classification is severely limited by aspect sensitivity. Inspired by the intrinsic complementarity between HRRP and LiDAR point clouds, this work investigates the feasibility and effectiveness of ...

Validity of different algorithmic methods to identify hospital readmissions from routinely coded medical data

Journal of Hospital Medicine, Volume 19, Issue 12, Page 1147-1154, December 2024.
Abstract Background Hospital readmission rates are used for quality and pay‐for‐performance initiatives. To identify readmissions from administrative data, two commonly employed methods are focusing either on unplanned readmissions (used by the Centers for Medicare & Medicaid Services, CMS) or potentially avoidable readmissions (used by commercial ...
