Diffusion‐Weighted Imaging for the Evaluation of the Sacroiliac Joint in Pediatric Patients
Arthritis Care &Research, EarlyView.Objective Maturational signal in the sacroiliac joint (SIJ) of skeletally immature youth is often misinterpreted as inflammation. Diagnostic tools that improve specificity are greatly needed. Apparent diffusion coefficient (ADC) values from diffusion‐weighted imaging (DWI), when used with standard imaging, may enhance diagnostic accuracy.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

A novel procedure to adjust the equivalent circuit parameters of photovoltaic modules under shading [PDF]
, 2020 6noCommercial PhotoVoltaic (PV) modules generally consist of a number of PV cells ranging between 60 and 96. The solar cells in a PV module are connected in series and partitioned in 3 or 4 strings, each protected by a bypass diode.

Cabling Constraints in PV Array Architecture: Design, Mathematical Model and Cost Analysis
IEEE Access, 2020 In this article, cabling constraints of different photovoltaic (PV) configurations is addressed in three steps: 1) a cable selection criterion is developed in accordance with metric system defined by American Wire Gauge (AWG); 2) a mathematical model is ...
