Application of Electrical Capacitance Tomography for Imaging Conductive Materials in Industrial Processes

Journal of Sensors, Volume 2019, Issue 1, 2019., 2019
This paper presents highly robust, novel approaches to solving the forward and inverse problems of an Electrical Capacitance Tomography (ECT) system for imaging conductive materials. ECT is one of the standard tomography techniques for industrial imaging. An ECT technique is nonintrusive and rapid and requires a low burden cost. However, the ECT system

Global Stabilization of Nonlinear Networked Control System with System Delays and Packet Dropouts via Dynamic Output Feedback Controller

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
The stabilization problem is investigated for a class of nonlinear discrete‐time networked control systems (NCSs). Nonideal network Quality of Services (QoS) are considered, more specifically data packet dropouts and network‐induced delays. A state feedback controller for a class of NCSs is proposed.

Operando Structural Rearrangement of Self‐Ion‐Implanted Germanium Films Enables High‐Rate Cycling in Lithium‐Ion Batteries

physica status solidi (a), Volume 223, Issue 7, 7 April 2026.
Nanostructured germanium thin‐film negative electrodes are produced by combining PECVD deposition with self‐ion implantation, enabling battery fabrication fully compatible with semiconductor processing workflows and without material removal. The resulting porous structure dynamically rearranges during high‐rate cycling, leading to improved rate ...

On X‐valued sequence spaces

International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 1, Page 47-50, 1997., 1995
Certain spaces of X‐valued sequences are introduced and some of their properties are investigated. Köthe‐ Toeplitz duals of these spaces are examined.
