Context. Under conditions of simultaneous exposure to active and passive interference, the passive component decorrelates the active component of the combined interference in the receiving channels of the surveillance radar, which significantly reduces th... see more

The problem of training sample reduction is considered. A method for data reduction based on association rules is developed. The proposed method of training sample dimensionality reduction includes stages of reduction of instances, features and redundant ... see more

Contex. To ensure noise immunity of modern radar stations, two-stage space-time signal processing is used. However, withsimultaneous exposure to active and passive interference, the latter decorrelates the active interference. This significantly limits th... see more

Context. In the conditions of combined clutter and jamming radar performance is significantly degraded. This is due to the decorrelation of a point source of an active jamming by spatially distributed passive clutter. The methods of forming classified tra... see more

The problem of training sample forming is solved to automate the construction of neural network models on precedents. The samplingmethod is proposed. It automatically selects the training and test samples from the original sample without the need for down... see more

Radar effectivenes is dramatically decreasing in the case of combined interference. This is due to decorrelation of a point source jammerby spatially distributed structure of passive interference.There have been considered limitations arising from the for... see more

AbstractBackground: There is an increasing amount of blood sample rejection at primary health care facilities (PHCFs), impacting negatively the staff, facility, patient and laboratory costs.Aim: The primary objective was to determine the rejection rate an... see more

This study aimed to explore the effectiveness of a computerized training program to develop the skills of phonology awareness to activate the reading and writing abilities of a sample of talented students with learning disabilities. The sample consisted o... see more

The implementation of the commitments agreed upon in the Europe 2020 Strategy, coupled in a transversally way, the integrated development of multiple policies and work strategies in the educational, social and professional areas. In particular, and by elo... see more
