Fuzzy Logic for Incidence Geometry [PDF]
The paper presents a mathematical framework for approximate geometric reasoning with extended objects in the context of Geography, in which all entities and their relationships are described by human language. These entities could be labelled by commonly

Design, Implementation, and Verification of High-Accuracy Trapezoidal Dual-Axis Sun Sensors for LEO Satellite Attitude Determination [PDF]
This paper presents a dual-axis sun sensor employing a cross-slit aperture in conjunction with a four-quadrant trapezoidal photodiode layout. The cross-slit configuration enhances angular sensitivity and resolution, while the trapezoidal photodiode ...

Optimization of hydrofoil leading-edge geometry for delaying incipient cavitation using a CFD–GA approach [PDF]
Cavitation is a common phenomenon in hydraulic machinery, which brings negative impacts such as noise, vibration, performance drop and material damage into hydraulic turbomachinery.

Velocity Increment on Incidence Angle near the Leading Edge of the Compressor Cascade
The geometry of a compressor leading edge has an important effect on the aerodynamic performance at an off-designed incidence angle. The current geometric design methods of the leading edge are usually developed based on the flow characteristics at the ...

EFFICIENT SPATIO-TEMPORAL MODELLING TO ENABLE TOPOLOGICAL ANALYSIS [PDF]
Time-dependent analysis scenarios such as heat, wind or flood analysis in cities and in landscapes need a correct and consistent modelling of geometry and topology over time.

Numerical Investigation of External Electromagnetic Field Coupling to Coplanar Waveguide [PDF]
In this paper, for the first time, effects of external electromagnetic fields on a coplanar waveguide (CPW) are numerically studied by means of the method of finite elements. Two CPW lines with different geometry and dielectric substrate permittivity are
