The dust-free installation training system for Gas-Insulated Metal-Enclosed Switchgear (HGIS) is a key technology for the safe operation of the power system. This paper addresses the shortcomings of existing training methods and proposes a dust-free ...

This work addresses the problem of intelligent reflecting surface (IRS) assisted target sensing in a non-line-of-sight (NLOS) scenario, where an IRS is employed to facilitate the radar/access point (AP) to sense the targets when the line-of-sight (LOS) ...

In this paper, we introduce a sub-Nyquist sampling-based receiver architecture and method for wideband spectrum sensing. Instead of recovering the original wideband analog signal, the proposed method aims to directly reconstruct the power spectrum ...

Document layout analysis (DLA) is the task of detecting the distinct, semantic content within a document and correctly classifying these items into an appropriate category (e.g., text, title, figure). DLA pipelines enable users to convert ...

Low payload capacity is a flaw in pixel exchange-based reversible data hiding schemes. In order to improve it, this paper proposes a triangular pixel pair structure, which requires fewer pixels than a traditional 2 × 2 pixel block. At the same time, the ...

Proxy blind signature is a cryptographical technique and allows a proxy signer to produce a proxy blind signature on behalf of original signer, in such a way that the authority learns nothing about the message that is being signed. The unforgeability is ...

This paper describes and deduces the theory of Haar-like features, Integral image and AdaBoost algorithm, which were proposed by Paul Viola, and then researches its improvement. We combine Microsoft Visual C++6.0 with OpenCV Function library to develop ...

Anonymous authentication is an important means of authorizing a user without identification. It serves as a breakthrough to enhance the privacy of the user and yet preserve the security of the system. Due to limited bandwidth, permanent connections ...

High-quality boron nitride nanotubes were synthesized by annealing porous precursor in flowing NH₃ gas at 1150°C. The porous precursor B₁₈Ca₂(MgO)₉ was produced by self-propagation high-temperature synthesis (SHS) method using Mg, B₂O₃, and CaB₆ as the ...

In software coding practices, buffer overflow is most frequently used as a means of intrusion. Typically, an attacker is able to affect a successful intrusion by causing buffer overflow in the stack frame of a function call, thereby causing the valid ...

Recently, Das et al. proposed a dynamic ID-based remote user authentication scheme using smart cards. Liao et al. pointed out some weaknesses of Das et al.’s scheme, and presented an improved scheme. However, an impersonate attack on Liao et al.’s ...

In some cases, it is not necessary for anyone to be convinced a justification of signer’s signature. Motivated by the above case, in this work we propose a provably secure convertible limited verifier signature scheme which based on the CDH assumption ...

Recently, Seung-Hyun et al proposed a nominativeproxy signature scheme for mobile communication.However, we show that the scheme hasn't non-repudiation,note that a malicious original signer canforge the proxy signer to sign on any message. Finally,we ...
