Abstract:

This study introduces a parametric preliminary design of central core bracing tailored for towers and tall buildings dominated by dynamic flexural vibrations and handled by accidental and serviceability deflections. In such slender systems, the determination of the core thickness is of critical importance to structural engineers, as it formally validates the pre-project stage and, subsequently, enables proper structural detailing outcomes in accordance with seismic regulations and technical standards. This issue is a real challenge, as it typically entails an unlimited number of attempted iterations and enormous computational time to converge towards the optimal values of the structural load-bearing elements. To address this problem, we introduce a streamlined methodological approach, structured as a practical guideline, aimed at defining an optimal variation of the thickness profile and facilitating accurate structural sizing. This dynamic and structural optimization is governed by the max-min formulation of the natural frequency eigenvalue. For this, two strategic zones, depending on the height of the tower, were delineated. Additionally, the construction material usage quantity constraint is imposed to ensure its optimal consumption, thereby establishing a bridge between structural design maturity and the ambitions for increasing profits and resource savings. The principal advantage of this mechanical and mathematical resolution lies in its simplicity and practicality, allowing rapid and efficient hand-use calculations. The present paper is crowned by an illustrative case study designed to evaluate the tangible benefits achieved through the dynamic modal analysis.

Abstract:

When properly excited at visible or near-infrared wavelengths, plasmonic materials display distinct with interesting appearances which could be overworked in the design and tuning of optical emission with diffusion settings at nanoscale scales. Researchers have presented a diversity of plasmonic heterostructures through scientific studies and used them to filter, transmit, detect, and detect light waves. And the amendment. In this study, implementations of modern plasmonic schemes utilized in communications are summarized. Their distinct roles have been discussed in multiple paths, including beam focusing, directing, filtering, modulation, switching, as well as reception, all of which are of paramount interest to the improvements of sixth-generation (6G) cellular networks. An optical communications system has been simulated that simulates the implementation and use of plasmonic materials to filter optical waveforms and direct the communications beam in an efficient and focused manner while reducing the data reception error rate to an excellent rate to avoid noise waves and interference for the sixth generation.

Abstract:

Quantum computing represents both a major technological advance and an existential danger to contemporary encryption systems. Shor's algorithm can efficiently factor large integers and solve discrete logarithm problems on quantum computers, thereby undermining the security foundations of contemporary public-key cryptographic systems such as RSA, Elliptic Curve Cryptography (ECC), and Diffie-Hellman key exchange. This presents a considerable barrier to the computational complexity of our current lattice-based cryptography packages. This research presents a comprehensive FPGA (field programmable gate array) solution for the standard implementation of Crystal Kyber, the NIST-standardized post-quantum cryptographic key encapsulation mechanism. Subsequently, we executed and assessed Crystal Kyber on two distinct Xilinx platforms: Kintex UltraScale+, optimised for performance, and Zynq-7000, designed for embedded processing, utilising the Vivado 2018 design suite. Through the effective deployment of lattice-based cryptography on FPGAs, we tackled the significant computational complexity inherent in lattice-based encryption by using the many-body parallel processing capabilities and the programmable design of an FPGA. This study presents a realistic architecture that utilised just 764 and 781 LUTs, 388 flip-flops, 2.5 BRAM blocks, and 1 DSP slice. In total, power analysis reveals a total power consumption of 0.436 W for Kintex UltraScale+ and 0.127 W for Zynq-7000, despite being reported between 80-330× and 50-115× better efficiency when compared to other implementations. The development of post-quantum cryptographic hardware implementation opens the door for a foundation for growth into the practical execution of post-quantum cryptographic hardware implementations in resource-constrained and power-constrained environments in adherence to NIST security protocols.

MITIGATION OF SUPRAHARMONICS IN MICROGRIDS USING PARABOLIC CARRIER-BASED PWM-CONTROLLED SHUNT ACTIVE FILTERS

Abstract:

Microgrids (MGs) are having more difficulty sustaining power quality (PQ) as renewable energy sources (RES) become more widely integrated. The issue of supraharmonics (SH), characterized by high-frequency emissions spanning from 2 kHz to 150 kHz, holds significant importance. The switching processes used in these RES power electronic converters are to blame for these harmonics. Traditional passive filters and capacitor banks are ill-equipped to deal with the dynamic changes in system characteristics that occur at the PCC. Voltage swell, unbalance, and power factor problems result from this. The Shunt Active Filter (SAF) has shown superior efficacy in mitigating harmonic issues in power systems. Nonetheless, its performance is contingent upon the rapidity and precision of its control algorithms. This paper employs the parabolic carrier-based pulse-width modulation (PWM) technique to regulate current in SAF, thereby minimizing SH. This method incorporates using a pair of positive and negative parabolic PWM carriers to control the switching states of the two switches in the converter phase leg, simultaneously constraining the current tracking error within the nonlinear parabolic region. The proposed filter is designed using the MATLAB/Simulink environment and used in a modelled MG with specified ratings. The results of the harmonic analysis showed a distortion contribution in the SH range of merely 0.03%. The minimal increase in THD when extending the analysis up to 150 kHz demonstrates the active filter’s effectiveness in suppressing SH.

A LIGHTWEIGHT EDGE-LAYER GROUP KEY AGREEMENT PROTOCOL FOR IOT USING ELLIPTIC CURVE CRYPTOGRAPHY AND SHAMIR’S SECRET SHARING

https://doi.org/10.26782/jmcms.2025.11.00007

Abstract:

A Group Key Agreement Protocol enables secure multi-party communication by establishing a common cryptographic key, which is especially critical at the edge layer of IoT networks where devices often operate in decentralized and resource-constrained environments. However, existing protocols face several challenges, including high computational overhead, single points of failure, and a lack of integrity validation during the Distribution of the Group Key. To address these challenges, we propose a lightweight edge-layer protocol that combines Shamir’s Secret Sharing Scheme (SSS) and Elliptic Curve Cryptography (ECC) for secure and efficient group key distribution among IoT edge devices. ECC (Curve25519) is used for secure peer-to-peer sharing, with key sizes that are 12 times smaller and operations that are four times faster than traditional RSA. SSS splits the group key into shares and reconstructs it using a threshold, reducing computation and eliminating the need for full key generation on each device. It also removes single points of failure because no device retains the complete key. ECC enables secure peer-to-peer exchange of encrypted shares using ChaCha20 for efficient confidentiality. ChaCha20 enhances encryption speed, performing nearly three times faster than AES on resource-constrained devices. To ensure shared authenticity and detect tampering, HMAC is applied. This offers a lightweight integrity check suitable for constrained IoT devices. The proposed protocol is quantitatively validated through entropy and key-strength analysis, confirming 128-bit equivalent security and O(n) scalability up to 100 nodes. Communication-cost evaluation demonstrates low bandwidth overhead, while formal verification using BAN Logic and ProVerif under the Dolev–Yao adversarial model establishes confidentiality, authenticity, and forward secrecy with provable resilience against replay, impersonation, and man-in-the-middle attacks.

Abstract:

This study introduces a novel system called Generalized Joint Permutation-Carrier Index Modulation Based MC-DCSK (GJPC-IM-MCDCSK) aimed at enhancing energy efficiency, spectral efficacy, and data transmission rates of GCI-DCSK technology by generating and utilizing permuted forms of the reference chaotic series with quasi-orthogonal properties to distribute the modulated bits across each operational carrier. Furthermore, rather than employing correlation detection, the receiving end of the proposed system utilizes greedy detection to streamline the process. Evaluating the data rate, spectral efficiency, and complexity of the proposed GJPC-IM-MCDCSK system against GCI-DCSK, CI-DCSK1, and MC-DCSK technologies illustrates the superior performance of the recommended design. To illustrate the proposed design's superiority, the simulated Bit Error Rate (BER) performance is evaluated for the GJPC-IM-MCDCSK scheme and compared with the GCI-DCSK, CI-DCSK1, and MC-DCSK systems under AWGN and multipath Rayleigh fading channels.

INTERVAL-VALUED OPEN SETS VIA MINIMAL AND MAXIMAL IN INTERVAL-VALUED TOPOLOGICAL SPACES

Abstract:

This study aims to develop and investigate several classes of interval-valued sets within the framework of Interval-Valued topology. Interval-Valued sets, originally proposed by Yao and later enriched through various generalizations, provide a more expressive structure for modelling uncertainty than classical or fuzzy sets. In this paper, we introduce and analyse different categories of Interval-Valued sets, particularly focusing on their weak and strong forms, and we explore how these forms influence topological behaviour. Special emphasis is placed on the study of minimal and maximal Interval-Valued open sets, pre-open sets, and semi-open sets, which serve as extremal elements in the lattice of Interval-Valued topologies. We also examine the interrelationships between various kinds of Interval-Valued closed sets and their generalized counterparts, thereby clarifying how such structures are embedded within the hierarchy of Interval-Valued topology. By establishing these connections, we provide a deeper understanding of the internal organisation of generalized closed sets in this setting. To support the theoretical results, illustrative and carefully constructed examples are presented, which highlight both the necessity and the distinctions among the introduced concepts. Overall, this work contributes to the enrichment of Interval-Valued topological theory and lays the foundation for further applications in mathematical modelling and decision-making under uncertainty.
