PSSPR: A Source Location Privacy Protection Scheme Based on Sector Phantom Routing in WSNs [PDF]

2021 IEEE Intl Conf on Dependable, Autonomic and Secure Computing, Intl Conf on Pervasive Intelligence and Computing, Intl Conf on Cloud and Big Data Computing, Intl Conf on Cyber Science and Technology Congress (DASC/PiCom/CBDCom/CyberSciTech), 2021
Source location privacy, occupying an unshakable status in wireless sensor networks, has a profound influence on the widespread application of wireless sensor networks (WSNs). Most privacy policies that introduce phantom nodes to the source location have

Phantom maps and chromatic phantom maps [PDF]

American Journal of Mathematics, 2000
In the first part, we determine conditions on spectra X and Y under which either every map from X to Y is phantom, or no nonzero maps are. We also address the question of whether such all or nothing behavior is preserved when X is replaced with V Λ X for V finite. In the second part, we introduce chromatic phantom maps.

Construction and Evaluation of a Multipurpose Performance Check Phantom for Computed Tomography

Atom Indonesia, 2020
The use of computed tomography (CT) has become a common practice in medical diagnosis in Indonesia. Its number, however, is not matched by the availability of dedicated-performance-check phantoms. This paper aims to describe the design, construction, and

FPUS23: An Ultrasound Fetus Phantom Dataset With Deep Neural Network Evaluations for Fetus Orientations, Fetal Planes, and Anatomical Features

IEEE Access, 2023
Ultrasound imaging is one of the most prominent technologies to evaluate the growth, progression, and overall health of a fetus during its gestation. However, the interpretation of the data obtained from such studies is best left to expert physicians and
