Abstract. Climate is usually considered to depend on a large number of parameters, this being essentially a functional in multi-dimensional parameter space. We propose a low-dimensional model of a climate where the temperature field on a thermally conducting planet depends on the external energy input and very limited number of internal parameters, like thermal conductivity and reflectivity. Eq...

The note “Beskrivelse af et bærbart instrument til måling af vejbelægningers refleksionsegenskaber” (in Danish) explains that the two values of the reduced luminance coefficient, r1 and r2, of a road surface lead to the both of the characteristic values for the reflection properties of road surfaces. These are the specular factor S1 and the average reflection measured by either the average lumi...

Microwave coagulation therapy (MCT) has been employed mainly for treatment of small size tumors. In the treatment, thin microwave antenna is inserted into the tumor and microwave energy heats up the tumor up to at least 60 degrees C for generation of enough coagulated volume including the target tumor. During the microwave radiation, reflection coefficient of treatment antenna changes significa...

An ultra-wideband (UWB) microstrip filter with a fractional bandwidth (FBW) of more than 100% is designed and demonstrated. This UWB microstrip-filter design is based on a circuit model for an optimum short-circuited stub transmission-line filter whose unit Figure 4 Reflection coefficient of the ultra-thin absorber: (a) simulated reflection coefficient; (b) measured reflection coefficient; (c) ...

In a previous paper the authors analyzed and discussed the specular reflection coefficient of a plane boundary comprised of a plate, a compliant layer, and a fluid. The analysis showed that a negligible specular reflection coefficient may be derived provided specific resonance conditions are met. The resonance of concern is that between the surface mass of the plate and the surface stiffness of...

A cylindrical treatment of the configuration of small molecules in solution has been proposed. Cylindrical dimensions were obtained from Fisher-Hirschfelder molecular models, and these dimensions were used in an analysis of three sets of reflection coefficient values from the literature. The correlation between solute dimensions and the reflection coefficient was subjected to both statistical a...
