Radiation-shielding concrete: A review of materials, performance, and the impact of radiation on concrete properties
Published in: Journal of Building Engineering
Nov 15, 2024
The efficiency of radiation shielding is crucial across industries having radioactive activities, from medical facilities to nuclear power stations. Radiation-Shielding Concrete (RSC) emerges as the preferred material for its cost-effectiveness, robust mechanical performance, ease of production, and excellent radiation attenuation properties against ionizing radiations such as gamma rays, X-rays, and neutrons. This comprehensive review delves into the evolution of SCI indexed research on concre...
Response of Overhanging RC Beams Strengthened with Various Schemes of Externally Bonded CFRP Strips
Published in: Practice Periodical on Structural Design and Construction
Nov 01, 2024
This study evaluated the effectiveness of carbon fiber-reinforced polymer (CFRP) composites in strengthening RC beams for a simple span overhanging from both ends and subjected to equal concentrated forces at each end. This innovative loading configuration allows for investigating the performance of CFRP composites under pure moment within the middle span and ensuring continuity of the moment over the supports, which cannot be captured using the classical simple span with four-point loading con...
Access Control Verification in Smart Contracts Using Colored Petri Nets
Published in: Computers
Oct 22, 2024
This paper presents an approach for the verification of access control in smart contracts written in the Digital Asset Modeling Language (DAML). The approach utilizes Colored Petri Nets (CPNs) and their analysis tool CPN Tools. It is a model-driven-based approach that employs a new meta-model for capturing access control requirements in DAML contracts. The approach is supported by a suite of tools that fully automates all of the steps: parsing DAML code, generating DAML model instances, transfo...
On computation of solution for (2+1) dimensional fractional order general wave equation
Published in: Partial Differential Equations in Applied Mathematics
Oct 03, 2024
In this research article, we handle a class of (2+1) dimensional wave equations under fractional-order derivatives using an iterative integral transform due to Laplace. The concerned derivative is taken in the Caputo's sense. The proposed method is a purely algebraic manipulation approach to compute solutions without a priori knowledge of geometry and physical meaning related to the proposed problem. In fact, in this procedure, we combine two novel techniques, Laplace transforms (LT) and iterat...

This paper introduces a compact dual-element multiple-input multiple-output (MIMO) implantable antenna for high-data-rate wireless capsule endoscopy (WCE) applications. The proposed antenna works at 915 and 2450 MHz with respective fractional bandwidths (FBWs) of 23.6 and 12.14%. The two-port MIMO system consists of two triangular-shaped radiators arranged face-to-face, forming a square configuration. The edge-to-edge distance between the radiators is 0.3 mm, indicating that the radiating eleme...
