The increasing number of home burglaries highlights the necessity for more advanced security solutions. Traditional security systems primarily focus on perimeter defences, which may not be sufficient in preventing intruders who have already entered the premises. This study introduces an innovative anti-theft flooring system designed to strengthen home security by providing an additional layer of protection beyond standard alarms. The system is activated when the homeowner is away, enabling real-time monitoring and instant alerts to ensure a rapid response.

A refrigerator compressor was implemented with a PID controller and temperature settings to control tarpaulin sealing machine capabilities. The sealing process was optimized for various tarpaulin materials through pressure and temperature combinations. For HDPE, optimal welding was achieved at 100 Psi and 140°C, yielding 6.22 N/m² weld strength with 3.2 Amps consumption. LDPE required 70 Psi and 115°C for 0.81 N/m² strength using 2.7 Amps, while PVC needed 80 Psi and 125°C for 1.80 N/m² strength consuming 2.9 Amps. The system was designed as a cost-effective alternative to conventional machines for sealing tents, canopies, billboards, and shop covers..

Seismic vulnerability of soft storey and vertical irregular structures is a significant issue in structural engineering. Structures with open ground storeys, mass irregularity, and discontinuity have greater risks during earthquakes, mainly because of the concentration of forces and large displacement at certain storey levels. This review consolidates evidence from a series of investigations, with prominent features of seismic analysis of soft storey and irregular structures including modeling approaches, performance parameters, and code standards. The observations suggest the implementation of design solutions like shear walls, bracing, and strengthening of stiffness distribution to enhance seismic resilience. Suggestions are also given for future study directions with special emphasis on superior analytical approaches and hybrid structural measures.

In this study, we propose an optimized voltage control system and a maximum power point tracking (MPPT) approach for proton exchange membrane fuel cells (PEMFC) using fuzzy logic control (FLC) integrated with multi-objective particle swarm optimization (MOPSO). PEMFCs are known for their potential in clean energy applications, but one of the key challenges is to efficiently regulate the output voltage while ensuring that the system operates at its maximum power point. This work addresses the nonlinearity and dynamic characteristics of PEMFCs by leveraging fuzzy logic, which is adept at handling uncertainties and providing robust control in complex systems.......

Cultural heritage assets consist part of the history and the identity of civilizations. The prevalent method of construction up to the early 20th century for cultural heritage (CH) buildings was unreinforced masonry (URM) structures.These structures are particularly exposed to seismic and climate change risk, because they were conceived according to empirical rules, considering only gravitational loads. The devastating impacts of natural hazards due to climate change and seismic events of the last century, especially in the Mediterranean region with earthquake prone countries........

HFO-1234yf (2,3,3,3-tetrafluoropropene) is a recently launched refrigerant, which is proposed to substitute HFC-134a in air-conditioning and refrigeration systems. HFO-1234yf has a very low global warming index with an atmospheric lifetime 500 times lower than HFC-134a and has similar properties. It ensures minor changes in components if retrofitting is applied. Thermodynamic properties play an important role in developing thermal systems, either refrigeration or power systems. The fundamental equation of state provides the best solution to approximate thermodynamic properties in an area not covered by the experiments of HFO-1234yf.........

Distributed PV power generation poses challenges to grid scheduling and stable operation due to the intermittent, nonlinear, and nonstationary characteristics of power output[1]. Traditional prediction methods rely on artificial features and a single model, which are difficult to capture complex spatio-temporal correlations; the classical Extreme Learning Machine is highly efficient in training, but suffers from limited generalization performance and insufficient deep feature extraction. In this study, we propose an improved ELM prediction method that integrates deep feature learning and adaptive optimization, and constructs a framework of "data denoising - hierarchical feature extraction - parameter optimization" to improve prediction accuracy and robustness.

A platform has been developed for the measurement, transmission, and real-time data processing of various physical, chemical, biological, and other water quality parameters in river systems. The platform continuously monitors and collects data, comparing measured values against legally defined water quality standards in a unified and integrated manner. It provides real-time information to support natural resource management. Water parameters are monitored using an industrial SCADA (Supervisory Control and Data Acquisition) system. The monitoring system consists of a central station, a local station, and multiple mobile monitoring units........

This study explores a sustainable wastewater treatment solution using microalgae species Chlorella vulgaris and Scenedesmus obliquus in an Inverse Fluidized Bed Reactor (IFBR). The system was designed to treat high-strength industrial effluent sourced from the Rourkela Steel Plant. Performance was assessed through BOD and COD reduction under both sterilized and non-sterilized conditions. Over a 7-day treatment cycle, the algae-IFBR system achieved up to 77.05% COD and 78.13% BOD removal in non-sterilized wastewater, indicating the synergistic potential of algae and native microbial communities.........

Heavy metal contamination in water bodies poses a serious threat to ecosystems and human health. This study investigates the potential of rice husk, an agricultural waste product, as a low-cost and sustainable biosorbent for the removal of lead (Pb2+), copper (Cu2+), and zinc (Zn2+) from synthetic wastewater. Two forms of rice husk—Grounded Rice Husk (GRH) and Carbonized Rice Husk (CRH)—were prepared and evaluated for their adsorption capacity under varying conditions. Characterization was performed using SEM and XRF analyses to assess morphological and elemental properties.........
