A Lookup Table-Based Method for Estimating Sea Surface Hemispherical Broadband Emissivity Values (8–13.5 μm)

A Lookup Table-Based Method for Estimating Sea Surface Hemispherical Broadband Emissivity Values (8-13.5 μm)

Sea surface hemispherical broadband emissivity (BBE, 8–13.5 μm) is a vital parameter for calculating surface radiation budgets. Such data are currently unavailable. This paper proposes a lookup table-based method for retrieving sea surface hemispherical BBE values. The physically-based sea surface emissivity model of Wu and Smith, together with the optimal refractive index, were used to generat...

A Lookup Table Method for Optimal Transistor Network Synthesis

This paper presents a lookup table based method for switch networks and logic gates implementation. The proposed approach is able to deliver optimal transistor networks for all Boolean functions up to four inputs. Results show a new transistor count lower bound for P-class and NPN-class for four inputs logic gates.

A New Method for the Estimation of Broadband Apparent Albedo Using Hyperspectral Airborne Hemispherical Directional Reflectance Factor Values

The broadband albedo values retrieved from satellite sensors are usually compared directly to ground measurements. Some authors have noted the necessity of high spatial resolution albedo estimates to fill the gap between ground measurements and satellite retrievals. In this respect, hyperspectral airborne data with high spatial resolution is a powerful tool. Here, a new operational method for t...

Recti cation Method for Lookup-Table Type FPGA's

Field programmable gate array (FPGA) makes rapid pro-totyping an easier task, and is useful in many applications due to its growing speed and capacity. In this paper, we present a rectiication method for look-up table type FPGA's. Instead of changing the netlist of a circuit, we only modify functionality realized by look-up tables and keep the netlist equal so that there will be no change on th...
