Spatiotemporal Approach to Assess the Impact of Urbanization Policies on Urban Expansion and Sprawl Using Remote Sensing in Tiaret, Algeria

Abstract This study examines the spatial implications of urbanization policies on urban expansion and sprawl. While the shortcomings of urban containment policies have garnered considerable scholarly attention, policies promoting urbanization remain underexplored, with limited em...

Rain-Gated Retractable-Roof Control in Semi-Arid Greenhouses: Why Threshold Rules Fail and What Predictive Aperture Control Buys

Protected cultivation in semi-arid regions is irrigated almost entirely from groundwater that is frequently brackish, while rainfall is shed off the greenhouse cover and lost. Retractable-roof greenhouses make it physically possible to admit that rainfall directly to the crop, an...

Current-vector trajectory–based diagnosis of open-circuit faults in NPC inverters for SSSC applications

Abstract This paper presents an enhanced fault diagnosis method for identifying open-circuit faults in the switches of Three-Level Neutral Point Clamped (NPC) inverters integrated into Static Synchronous Series Compensator (SSSC) systems. Although previous studies have mainly foc...

Real-Time Leader-Follower UGV-UAV Cooperation: Experimental Validation and Control Analysis

Abstract This paper presents the experimental validation of a real-time leader–follower cooperative control architecture for a heterogeneous system composed of a differential-drive Unmanned Ground Vehicle (UGV) and a quadrotor Unmanned Aerial Vehicle (UAV). In the proposed framew...

Ajuga reptans L. from Romanian flora as a promising candidate for novel food applications

The increasing demand for natural ingredients with both functional and sensory properties has stimulated the exploration of underutilised plant species as potential sources for novel food applications. Ajuga reptans L. (Lamiaceae) remains relatively underexplored despite its phyt...

Advanced MPPT Optimization for PV Water Pumping with Battery Storage and MPC-Driven BLDC Motor via Swarm and Evolutionary Algorithms

Photovoltaic (PV) pumping systems offer a sustainable alternative to diesel solutions, yet their nonlinearity, intermittent irradiation, and complex motor-pump dynamics challenge energy extraction and reliability. Currently, these systems predominantly rely on classical Maximum P...

Chemical Composition and Antibacterial Activity of Lavandula spica L essential oil from Algeria

Lavandula spica L, a species within the Lamiaceae family, is a plant native to Algeria, widely recognized and utilized for various purposes. The study aimed to determine the chemical composition of the essential oil and its antibacterial evaluation. Chemical composition of the es...

Layer-aware deep feature optimization for privacy-preserving face biometrics with revocable key binding

Abstract Biometric cryptosystems designed with revocability and session-level renewability must preserve template privacy and maintain reliable authentication despite the inherent variability of biometric data. A key unresolved issue in deep biometric protection is how the embedd...
