Abstract – In this paper we present an algorithm for fast geolocation of hot spots from an infrared image taken from an unmanned aircraft. The input data are the position and attitude of the aerial platform, and the digital elevation model of the terrain. The down faced orientation of the camera and the stable flight of the aircraft contribute to reduce the number of floating point operations needed for geolocation. These simplifications will result on an increase of the accumulated errors, added to those of the measuring instruments. In the paper we will compare the geolocation results of the complete computational model with the proposed fast model.

Spatial smoothing and hot spot detection for CGH data using the fused lasso.
We apply the "fused lasso" regression method of (TSRZ2004) to the problem of "hot- spot detection", in particular, detection of regions of gain or loss in comparative genomic hybridization (CGH) data. The fused lasso criterion leads to a convex optimization problem, and we provide a fast algorithm for its solution. Estimates of false-discovery rate are also provided. Our studies show that the n...
متن کامل"Hot spot" on hepatic scintigraphy [Persian]
Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.
متن کاملVoltage-Based Hot-Spot Detection Method for Photovoltaic String Using a Projector
This paper proposes a voltage-based hot-spot detection method for photovoltaic (PV) string using the projector. Hot-spots form in solar cells at defects causing a high carrier recombination rate, it appears as a high reverse leakage current of p-n junctions when solar cells are partially shadowed. Using this characteristic, authors previously developed a voltage-based hot-spot detection method ...

Fatigue analysis and estimation of safe life of structures that are subjected to cyclic loadings, such as ships and offshore structures is one of the most important steps of structural design. Fatigue failure in the form of crack will start from details and propagate in structure. In steel structures these cracks will started from welds. Most of the methods for fatigue life assessment in welded...
