COMPUTATIONAL INTELLIGENCE IN NUCLEAR ENGINEERING

Approaches to several recent issues in the operation of nuclear power plants using computational intelligence are discussed. These issues include 1) noise analysis techniques, 2) on-line monitoring and sensor validation, 3) regularization o...

Sharing tactical data in a network-enabled coalition

The NATO Command, Control and Consultation Agency (NC3A) is a participant in a coalition project called the Shared Tactical Pictures (STP). The aim of STP is to develop methods and techniques to enable the sharing of a wide variety of infor...

Three-dimensional structure and formation mechanisms of Y2O3 hollow-precipitates in a Cu-based metallic glass

Recently, the high ductility of Cu-based bulk metallic glasses (BMGs) has been directly linked to the presence of Y2O3 precipitates, and surrounding crystallized areas. Nevertheless, the formation of the precipitates remains to be defined. ...

Blind Dual Watermarking Scheme Using Stucki Kernel and SPIHT for Image Self-Recovery

In this paper we propose a blind dual watermarking scheme using Set Partitioning in Hierarchical Trees (SPIHT) and Stucki Kernel halftone technique for the tamper detection and image self-recovery. The watermark consists of authentication b...

Correction to “5.8 GHz 4-Channel Beamforming Tx IC for Microwave Power Transfer”

In the above article [1], the received power in dc referred from the reference [2], which is the reference [35] in the original article [1], was incorrectly introduced. It was written as 0.2 W (dc) in the introduction of [1], ...

A Rechargeable Zinc–Copper Voltaic Battery Built from Cost-Effective Electrodes and Electrolytes

The zinc–copper (Zn-Cu) voltaic battery is the first battery made in human history, but the Cu2+ dissolution issue leads to the reaction’s irreversibility. To tackle this challenge, solid-state electrolytes, ion exchange membranes, and func...

DC-Sync: A Doppler-Compensation Time-Synchronization Scheme for Complex Mobile Underwater Sensor Networks

Time synchronization is crucial for effective collaboration among underwater sensors. However, existing synchronization protocols primarily cater to low-speed or simple motion scenarios, neglecting variations in radial velocity during messa...

A novel generalized sliding mode controller for uncertain robot manipulators based on motion constraints

To improve the trajectory tracking performance and robustness for uncertain robot manipulators, a generalized sliding mode controller (GSMC) including an ideal controller and a continuous sliding mode controller (SMC) is proposed from the s...

工频叠加操作冲击电压下预制式电缆终端破坏机理研究

工频叠加操作冲击电压是电缆运行中时常面临的情况，在该情况下高频谐波电压会使电缆终端材料介电常数发生变化，进而造成电缆终端所承受的电应力、热应力和机械应力发生改变，最终会对电缆终端的绝缘造成破坏。文中，首先建立了工频叠加操作冲击电压的数学模型，同时分析了不同冲击电压叠加相位对叠加后电压波形的影响；其次，利用有限元软件建立了35 kV预制式电缆终端的仿真模型，对仿真模型参数设置、边界条件设置以及网格剖分设置进行了详细说明；最后，仿真计算了工频叠加操作冲击电压下电缆终端应力情况，包...

ATIB: Design and Evaluation of an Architecture for Brokered Self-Sovereign Identity Integration and Trust-Enhancing Attribute Aggregation for Service Provider

Identity management is a principle component of securing online services. In the advancement of traditional identity management patterns, the identity provider remained a Trusted Third Party (TTP). The service provider and the user need to ...

A new insight on the diffusion growth mechanism of intermetallic compounds in Al-Er system

The diffusion growth of intermetallic compounds in Al-Er alloys are closely related to the properties of the alloys. The current work aims at explaining the dominance of Al3Er in the Al-Er alloys precipitation phases and the interface thin ...

Critical thickness of GaN film in controllable stress-induced self-separation for preparing native GaN substrates

Stress-induced self-separation is one of the most efficient process for preparing native GaN substrate. The control of GaN film thickness is the key point for GaN film separating from substrate completely. Considering the bowing of bilayer,...

Graph Theory-Based Approach to Accomplish Complete Coverage Path Planning Tasks for Reconfigurable Robots

Extensive studies regarding complete coverage problems have been conducted, but a few tackle scenarios where the mobile robot is equipped with reconfigurable modules. The reconfigurability of these robots creates opportunities to develop ne...

R-Local Unlabeled Sensing: A Novel Graph Matching Approach for Multiview Unlabeled Sensing Under Local Permutations

Unlabeled sensing is a linear inverse problem where the measurements are scrambled under an unknown permutation leading to loss of correspondence between the measurements and the rows of the sensing matrix. Motivated by practical tasks such...
