The weather radar–based object-oriented convective storm tracking is a standard approach for analyzing and nowcasting convective storms. However, the majority of current storm-tracking algorithms provide nowcasts only in a deterministic fashion wit

This paper proposes a method for classifying the severity of individual convective storms with real-time weather radar and lightning location data. The algorithm is based on a statistically initialized fuzzy logic model with human-oriented linguistic

Convective storms cause several types of damage, including economic and ecological losses, every year. This paper focuses on an automatic hazard-level determination of convective storms based on a largely unused information source: real-time emergenc

Testing measurements against quantiles of their distributions is a basic quality control technique. Unfortunately, the methods for the empirical quantile computation require usually ordered observations, which is not feasible for on-line use in large

Automated quality control is a necessity for meteorological measurement networks because of an ever-increasing number of measurements. One of the basic quality control tests is to check that the observations fall into a range of acceptable values. Th

Flotation is one of the most important mineral concentration techniques. It is known that the appearance of the froth in the flotation cells tells much about the state of the flotation process. A machine vision measurement device was used to compute

This paper takes a unified approach to the downlink transmission power control, while a transmission beamforming is applied in the base station. The proposed scheme is based on the estimation of signal-to-interference-and-noise-ratios (SINRs) by ante

This paper examines Kalman filtering and three suboptimal methods in the case of delayed and out-of-sequence measurements in networked or wireless systems. The motivation for suboptimality for Kalman filtering stems from the low computational resourc

Maintenance and repairing of widely distributed and large scale networks of sensors and actuators can easily become overwhelming – physically and financially. This applies especially, if the units are located so that performing the maintenance oper

In widely distributed measurement systems, the first guess for the station measurement quality control is to compare the measurement to the neighbor stations. The basic degree of neighborness is often determined by the inverse distance of the measure
