Today's technological changes present some powerful risks, and we should ask ourselves whether we think such changes are worthwhile – because we do have choices in the technologies we make and live by ...

Abstract: Attribute-based encryption (ABE) requires several elliptic-curve-based functions, including elliptic-curve scalar multiplication (ECSM), hashing to the curve, and pairing. Although these ...

Abstract: Topology optimizations involving evolutionary algorithms are promising approaches to solve practical engineering design problems, since their use of derivation-free algorithms makes them ...

Abstract: Extracting ground points from LiDAR point clouds is essential for constructing digital terrain models (DTMs). This article presents a filtering method with strip curve fitting, based on the ...

Abstract: This article addresses the challenge of designing robust controllers for uncertain systems subject to multiple input and state constraints. A nonlinear ...

Abstract: Multilevel Green's function interpolation method (MLGFIM) is a fast numerical method whose computational complexity is O(N log N). Since MLGFIM is based on interpolation techniques, the ...

Abstract: Efficient obstacle avoidance while controlling unmanned maritime vehicles (UMVs) is an important topic. Evading obstacles that are both time-varying and shapechanging, such as avoiding ...

Abstract: The elastic modulus is a fundamental index of material stiffness, serving as a bridge that connects the microscopic characteristics of materials to their macroscopic engineering performance.

Abstract: This paper proposes a small-signal model for constant-on-time current mode controlled (CM-COT) Buck converters. As an improvement over existing models, the proposed model considers the ...

Abstract: Pollard's rho method is a widely used probabilistic algorithm for solving the Elliptic Curve Discrete Logarithm Problem (ECDLP). To enhance its efficiency, the skew Frobenius mapping (SFM) ...
