AI-based monkeypox detection model using Raspberry Pi 5 AI Kit
Monkeypox is a zoonotic disease that originated from monkeys and then spread to humans; this disease recently popped up globally with increased risks of spreading from human to human and clinical presentation similar to other pox-like diseases. Quick and right identification is fundamental for containment and treatment that will minimize the spread of the disease. The current conventional diagnostic techniques include PCR which takes time, and money, and often needs sophisticated laboratories that cannot be easily accessed in developing countries. This work describes the creation and application of a monkeypox detection algorithm orchestrated on the Raspberry Pi 5 AI Kit. Developed based on convolutional neural networks (CNNs), the model enables one to distinguish actual monkeypox lesions in the images. The Raspberry Pi 5 AI Kit allows for edge computing solutions to be implemented, making the entire solution mobile, affordable, and perfect for locations with low connectivity. Extensive data collection and data preprocessing were performed, and the final dataset with monkeypox and skin lesion images consisted of more than 5000 verified images. 94% accuracy was obtained by the model, making it superior to the model available in literature. The implementation proves that powerful AI technologies can be applied to low-cost hardware to become a valuable weapon in the monkeypox frontline workers’ arsenal and advance the efforts against monkeypox infections
Blockchain technologies and their application in security software development
Current factors like the rising frequency of cyber threats and vulnerabilities on centralized platforms indicate the inefficiency of conventional network security frameworks, leading to new solutions such as the blockchain. This review systematically reviews developments of blockchain technologies in the context of security software (2021-2023) to evaluate its efficacy and challenges and explore the future potential. 77 peer-reviewed papers from ScienceDirect, IEEE Xplore and Scopus; adopting the PRISMA guideline, records were screened down from 1,532 to 77. Empirical evaluations (35%), case studies (28%), and theoretical frameworks (37%) using Joanna Briggs Institute tools and the Newcastle-Ottawa Scale were used in mitigating bias. Our results show that blockchain has strengths that add to data integrity (89% of studies) and security of the Internet of Things (IoT) ecosystem (28 studies) and supply chains (15 studies). Nevertheless, blockchain-based authentication has reduced latency by 284% (342 ± 112 ms) compared to a traditional system and has tradeoffs with scalability and performance. Research is skewed towards finance (47%), missing healthcare (9%), and critical infrastructure (6%). It does not include sufficient interoperability standards, post-quantum cryptographic validation, etc. The adaptive regulations are urged for policy implications for editable blockchains and hybrid Artificial Intelligence (AI) blockchain architectures. Interoperability should be taken care of by cross-chain protocols, scalability trilemmas and real-world adversarial testing must be addressed by the researchers and practitioners must put priority on scalability. This review, in its totality, brings out the singular role of blockchain in complementing the existing security solutions instead of replacing them. It calls for cross-disciplinary involvement and partnership in harnessing technical innovation in a regulatory framework to tackle cybersecurity threats through outsider and insider security approaches

Reconfigurable metasurface based on graphene optical antennas for dynamic beam steering
Metasurface represents a transformative advancement in photonics due to its exotic abilities to control electromagnetic wave properties. The integration of graphene and metasurface propels metasurface to new heights of compact footprint, reconfigurability, and multi-functionality. In this article, a reconfigurable metasurface based on graphene optical antennas is designed as a reflective surface that controls the beam steering by tuning graphene’s Fermi energy based on the concept of a phase-shifting surface. The results demonstrated that the designed metasurface can dynamically steer the reflected beam at different reflection angles, in addition to their capability to reflect a single beam and three beams. The metasurface exhibits high gain and directivity at different reflection angles. These steering capabilities provide a potentially efficient method for developing and simplifying dynamic reconfigurable beam-steering systems
Wavelet decomposition and statistical characterization for unbalance detection in rotating systems
Vibration analysis is a crucial tool for the early detection of faults in rotating machines, as it allows for the prevention of major damage and avoids significant costs associated with these faults. This study examines the phenomenon of imbalance in rotating machines, using signals generated on a test bench at the Santander Technological Units, where specific fault conditions were replicated. The signals obtained were analyzed using wavelet decomposition, from which key characteristics were extracted, such as root mean square (RMS), peak value, kurtosis, and mean absolute value (MAV). These characteristics were then compared using box plots to evaluate the separation between signals from unbalanced machines and those in a fault-free state. This analysis allowed us to identify significant differences between the two conditions, demonstrating the effectiveness of the approach in detecting faults due to imbalance
A method of representing design solutions in complex systems through model-parametric spaces
On the side of highly complicated systems, it is necessary to have powerful frameworks that can present solution design integration and visualization in the best possible manner, dealing with clarity, scalability, and adaptability. This work aims to formulate an innovative approach for modeling design solutions using model-parametric spaces to create a systematically structured yet convenient method for dealing with multidimensional design complexities. This investigation is conducted within a mixed-method research design combining qualitative assessments of system architecture with quantitative modeling techniques to formulate parametric spaces where design variables and their interrelations are parameterized systematically. The validation of that methodology was done in a way that involves simulated operational scenarios and expert-driven evaluation, which shows the robustness and versatility of the understanding achieved using the approach in different fields of study. Results reveal the utility of model-parametric spaces in vastly increasing the interpretability, modularity, and optimization capability of complex design processes. Therefore, the study argues that this methodology framework is a solid and reasoned basis for decisions in the systems engineering domain and positively explains both research and industrial applications. These future research trajectories determined by this study include further extensive validation within actual project settings to make the developed software more applicable and impactful in the physical world
