In line with the critical comments formulated in relation to the S-shape global solar radiation estimation method, the original formula was improved via a 5-step procedure. The improved method was compared to four-reference methods on a large North-American database. According to the investigated error indicators, the final 7-parameter S-shape method has the same or even better estimation effic...

Imagine a tracking agent P who wants to follow a moving target Q in d-dimensional Euclidean space. The tracker has access to a noisy location sensor that reports an estimate Q̃(t) of the target’s true location Q(t) at time t, where ||Q(t)−Q̃(t)|| represents the sensor’s localization error. We study the limits of tracking performance under this kind of sensing imprecision. In particular, we invest...

For hyperspectral image research, spectral characteristic retainment is more important than the spatial details retainment, so it is necessary to evaluate the spectral influence of hyperspectral image compressed sensing. In this paper, the researchers select a hyperspectral remote sensing image PROBE CHRIS with abundant coastal wetland ground objects to analyze spectral fidelity of wavelet tran...

This paper presents some developments in query expansion and document representation of our Spoken Document Retrieval (SDR) system since the 1998 Text REtrieval Conference (TREC-7). We have shown that a modification of the document representation combining several techniques for query expansion can improve Average Precision by relative to a system similar to that which we presented at TREC-7 [1...

Determining the quality of an ongoing interaction in the field of Spoken Dialogue Systems is a hard task. While existing methods employing automatic estimation already achieve reasonable results, still there is a lot of room for improvement. Hence, we aim at tackling the task by estimating the error of the applied statistical classification algorithms in a two-stage approach. Correcting the hyp...

this paper presents mathematical models of thin layer forced convection solar drying of cuminum cyminum using two drying methods (mixed and indirect) at different operating conditions. the average initial moisture content of the seeds for all tests was about 43% d.b. and the drying was performed continuously, in each test, for a uniform period of 90 minutes drying time in a solar cabinet dryer ...
