A New Quadratic CUK-Based Step-Up DC/DC Converter Without Right Hand Plane Zero [PDF]

International Journal of Industrial Electronics, Control and Optimization
In this paper, a new transformerless high step-up DC/DC converter with low input current ripple for renewable energy generation systems. This introduced circuit is based on a conventional quadratic boost converter with a CUK circuit.

Classification of Watermelon Seeds Using Morphological Patterns of X-ray Imaging: A Comparison of Conventional Machine Learning and Deep Learning

Sensors, 2020
In this study, conventional machine learning and deep leaning approaches were evaluated using X-ray imaging techniques for investigating the internal parameters (endosperm and air space) of three cultivars of watermelon seed.

Structure‐preserving interpolation of quadratic‐bilinear systems via regular multivariate transfer functions

PAMM
AbstractFor the accurate modeling of real‐world phenomena, high‐dimensional nonlinear dynamical systems are indispensable. Quadratic‐bilinear nonlinearities are of particular importance since many systems with general nonlinearities can be remodeled into this form.

Multivariate Nonnegative Quadratic Mappings [PDF]

In this paper we study several issues related to the characterization of speci c classes of multivariate quadratic mappings that are nonnegative over a given domain, with nonnegativity de ned by a pre-speci ed conic order.In particular, we consider the ...

Comparison of empirical methods for estimation of quadratic transfer functions of low-frequency hydrodynamic loads

Ocean Engineering
This study compares three methods for estimating quadratic transfer functions (QTFs) of low-frequency hydrodynamic loads on floating structures from experiments: Cross-Bi-Spectral (CBS) analysis, Regression-Based (RB) estimation, and Harmonic Probing of Nonlinear Auto-Regressive eXogenous models (NARX-HP).

Beam search heuristics for quadratic earliness and tardiness scheduling [PDF]

In this paper, we present beam search heuristics for the single machine scheduling problem with quadratic earliness and tardiness costs, and no machine idle time. These heuristics include classic beam search procedures, as well as filtered and recovering

Asset Pricing Under The Quadratic Class [PDF]

We identify and characterize a class of term structure models where bond yields are quadratic functions of the state vector. We label this class the quadratic class and aim to lay a solid theoretical foundation for its future empirical application.
