Publicly Verifiable Secret Sharing Scheme with Provable Security against Chosen Secret Attacks

open access: yesInternational Journal of Distributed Sensor Networks, 2013
Secret sharing is an important aspect of key management in wireless ad hoc and sensor networks. In this paper, we define a new secure model of secret sharing, use the Lagrange interpolation and the bilinear cyclic groups to construct an efficient ...

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

open access: yesStructural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Bilinear Interpolation Image Scaling Processor for VLSI Architecure

open access: yesInternational Journal of Reconfigurable and Embedded Systems (IJRES), 2014
We introduce image scaling processor using VLSI technique. It consist of Bilinear interpolation, clamp filter and  a sharpening spatial filter. Bilinear interpolation algorithm is popular due to its computational efficiency and  image quality. But resultant image consist of blurring edges and aliasing artifacts after scaling. To reduce the blurring and

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

open access: yesStructural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Phenology of migrating game birds in Italy based on citizen science data

open access: yesWildlife Biology, EarlyView.
Studying the timing of the seasonal movements of migratory birds, known as migration phenology, is crucial for managing and conserving migratory bird populations. This is particularly important for migratory game bird populations in Europe because, according to the EU, migratory birds should not be hunted during their breeding season or during return ...

Visual Positioning Detection of EMU Brake Pad Based on Deep Learning

open access: yesChengshi guidao jiaotong yanjiu
[Objective]With the continuous development of the rail transit industry, its operation scale and safety requirements are constantly increasing. To address the issues of low efficiency, missed and false detections in the manual inspection of EMU (electric
