Development of a robust haze removal algorithm: assessment using temporally invariant targetsYing Zhang; Guindon, B.; Cihlar, J.
Geoscience and Remote Sensing Symposium, 2002. IGARSS apos;02. 2002 IEEE International
Volume 1, Issue , 2002 Page(s): 101 - 103 vol.1
Digital Object Identifier 10.1109/IGARSS.2002.1024954
Summary: A robust haze-removal algorithm based on the Haze Optimized Transformation (HOT) is applied to ETM+ imagery. Its effectiveness is evaluated using temporally invariant targets identified in a multi-temporal data set of scenes of WRS-2 Path15/Row29. In the data set, clear scenes serve as 'benchmarks' against which the effectiveness of haze removal can be assessed. In the quantitative assessment, two hundred coniferous forest patches were randomly sampled and served as 'benchmark' targets since they exhibit both spatial and temporal radiometric invariance on clear data. Comparisons were made of the radiometric characteristics of the patch population in hazy vs. de-hazed and de-hazed vs. clear image pairs. Results show that image contaminated by low to moderate haze can be significantly improved. Reductions of 20 to 90% in intra-scene radiometric dispersion have been achieved with the de-hazed scenes exhibiting residual dispersion levels comparable to those of the benchmark scenes.

Doubly fed induction generator using back-to-back PWM convertersand its application to variable-speed wind-energy generation

Abstract
The paper describes the engineering and design of a doubly fed induction generator (DFIG), using back-to-back PWM voltage-source converters in the rotor circuit. A vector-control scheme for the supply-side PWM converter results in independent control of active and reactive power drawn the supply, while ensuring sinusoidal supply currents. Vector control of the rotor-connected converter provides for wide speed-range operation; the vector scheme is embedded in control loops which enable optimal speed tracking for maximum energy capture from the wind. An experimental rig, which represents a 7.5 kW variable speed wind-energy generation system is described, and experimental results are given that illustrate the excellent performance characteristics of the system. The paper considers a grid-connected system; a further paper will describe a stand-alone system

Measuring asymmetric link bandwidths in Internet using a multi-packet delay model
Yu Lin; Haitao Wu; Shiduan Cheng; Wenyan Wang; Chonggang Wang
Communications, 2003. ICC apos;03. IEEE International Conference on
Volume 3, Issue , 11-15 May 2003 Page(s): 1601 - 1605 vol.3
Digital Object Identifier 10.1109/ICC.2003.1203872
Summary: Accurate measurement of network bandwidth is crucial for many flexible Internet applications and protocols. Based on a new multi-packet delay model, this paper presents a new algorithm called ALBP (asymmetric link bandwidth probing) to measure each hop's link bandwidth in both directions in an IP network, and uses the kernel density estimator to produce a final estimate. Compared with previous techniques, ALBP can eliminate (at least partially) the errors introduced by ICMP replies through the use of interarrival time of two probing packets, and avoid the problem of error accumulation. Simulation results show that ALBP is usually more accurate than both one-packet and packet tailgating techniques, and the bandwidth consumption of ALBP is close to that of packet tailgating.
