Joint phase error estimation and sparse scene restoration algorithms for frequency agile radar

IET Radar, Sonar & Navigation, 2021
Frequency agile radar (FAR) systems have been demonstrated to have outstanding performance in electronic counter‐countermeasures (ECCM). With increased bandwidth in which FAR can switch carrier frequency, the phase errorswill appear at the corresponding ...

Joint numerical range and its generating hypersurface

Linear Algebra and its Applications, 2010
The authors consider the joint numerical range \(W(H_1, \dots, H_n)\) of \(m\)-tuples of Hermitian matrices. Associated with an~\(m\)-tuple \(H_1, \dots, H_n\) there is the homogeneous polynomial \[ F(y_0,\dots, y_m) = \det (y_0I_n+ y_1H_1 + \dots + y_mH_m), \] which may be looked upon as a~hyperbolic form with respect to the point \((1, 0, 0, \dots, 0)

Numerical Shear Tests on the Scale Effect of Rock Joints under CNL and CND Conditions

Advances in Civil Engineering, 2020
The scale effect of rock joint shear behavior is an important subject in the field of rock mechanics. There is yet a lack of consensus regarding whether the shear strength of rock joints increases, decreases, or remains unchanged as the joint size ...

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

Fractal Model of Contact Thermal Stiffness

Machines, 2022
The continuity, self-similarity, and self-affinity of a microscopic contact surface can be described by the Weierstrass–Mandelbrot (W–M) function in fractal theory. To address the problems that the existing normal contact load fractal model does not take

Characterisation of contact pressure distribution in bolted joints [PDF]

, 2006
The quantification of contact area and pressure distribution in a bolted joint is essential information, as it determines the integrity of the coupling. Current bolted joint design standards are based on analytical solutions of the pressure distribution,

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
