Representation and approximation of the outer inverse AT,S(2) of a matrix A
, 2000 In this paper, we establish a basic representation and a representation theorem for the outer inverse AT,S(2) of a matrix A, which is the matrix X satisfyingXAX=X,R(X)=TandN(X)=S.We develop several specific representations and iterative methods for AT,S ...

Flexible Krylov Methods for Edge Enhancement in Imaging
Journal of Imaging, 2021 Many successful variational regularization methods employed to solve linear inverse problems in imaging applications (such as image deblurring, image inpainting, and computed tomography) aim at enhancing edges in the solution, and often involve non ...

A class of outer generalized inverses
Linear Algebra and its Applications, 2012 The notion of the Drazin generalized inverse in associative rings and semi-groups, introduced by the author of the present article [Am. Math. Mon. 65, 506--514 (1958; Zbl 0083.02901)] is as follows: Let \(S\) be a semigroup. An element \(b \in S\), is called the Drazin inverse of \(a\) if \(ab=ba,b=bab\) and \(a^{k+1}b=a^k\) for some nonnegative ...

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, EarlyView.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Vibration Cascade Control for Motor-Driven Deep-Sea Robot Cable System with Actuator Fault
Journal of Marine Science and Engineering, 2022 In this paper, we investigated the cascade controller of a motor-driven deep-sea robot cable system (MDRCS), which consists of the outer loop system and the inner loop system connected by a motor thrust with unknown factors, typically forming a crucial ...
