This paper presents a Raspberry Pi-based autonomous photovoltaic cleaning system that employs a dual-gate protocol combining YOLOv8n visual defect detection and INA219 electrical sensing to safely trigger water cleaning only for dusty panels with verified structural integrity, thereby maximizing power recovery while preventing unnecessary maintenance on damaged modules.
This paper proposes a fractional-order sliding mode control strategy for magnetic levitation systems that integrates fractional-order linear-quadratic-regulator theory with a half-derivative sliding condition and sigmoid-based smoothing to achieve robust, chattering-free target tracking with enhanced stability and performance compared to conventional integer-order methods.
This study employs a geometrical-physical approach to demonstrate that the reconstructed internal architecture of the Delphic Tholos, unlike the Epidaurian Thymele, possesses acoustic properties compatible with ritual instrumental performance, specifically supporting a diatonic framework associated with the aulos.
This comparative engineering study synthesizes evidence from California's high-penetration solar housing to propose a phased regulatory and technical roadmap for implementing native DC residential distribution in Peru, aiming to capture 9–20% energy savings from reduced conversion losses while addressing current gaps in Peru's AC-centric electrical codes and safety standards.
This paper highlights the superior performance of the advanced In-52MSS filler metal over traditional In-52 in nuclear welding applications due to its enhanced resistance to ductility dip cracking and hot cracking, while also validating locally developed, economically viable analogues that maintain stable properties across extreme temperatures.
This paper synthesizes evidence from Chile, New Zealand, and Japan to propose a circular-economy-based seismic retrofit protocol for Peru's vulnerable social housing, demonstrating that recycled-rubber elastomeric isolators and friction dampers offer a technically feasible, low-cost alternative to conventional solutions despite the need for local environmental validation.
This paper proposes NSET-Andes, a physics-informed federated edge digital-twin framework that adapts high-fidelity seismic monitoring methodologies from instrumented Tokyo towers to Peru's vulnerable, undocumented building stock by embedding structural dynamics models into a latency-resilient, bandwidth-efficient training loop, while establishing a normative roadmap for future empirical validation in Andean emerging economies.
Pokala HealthIntel is a no-PHI public-source healthcare evidence review workspace that ensures review claims remain auditably linked to explicit metadata and source boundaries, demonstrating a validated, low-latency system for organizing and verifying public health data artifacts without providing clinical decision support.
This structured narrative review synthesizes laboratory evidence on acrylic resin selection and lamination protocols for lower-limb prosthetic sockets while proposing an integrated, geometrically explicit mechanistic model for estimating resin quantities, ultimately highlighting the need for prospective clinical validation and standardization to improve structural integrity and patient outcomes.
This paper presents the design, machine learning-assisted optimization, and experimental validation of a 2.6 GHz single-element switched-beam antenna that utilizes a Random Forest algorithm to accurately predict beam direction and reflection coefficient, enabling reliable eight-direction beam switching for 5G sub-6 GHz applications.
