A new class of ageing distributions

The class of new worse/better than used in expectation on average (NWUEA/NBUEA) distributions is proposed. It is defined by the requirement that for each age t a weighted average of mean residual lives be greater/smaller than the life expectancy at birth. The weights are the shares of ages up to t in the steady state stock which results from cohorts whose density is to be classified. The NWUEA class has a second order stochastic dominance property whose first order counterpart defines the class of new worse than used in expectation (NWUE) distributions.NWUE distribution; stochastic dominance

Fusion of hyperspectral and ground penetrating radar to estimate soil moisture

In this contribution, we investigate the potential of hyperspectral data combined with either simulated ground penetrating radar (GPR) or simulated (sensor-like) soil-moisture data to estimate soil moisture. We propose two simulation approaches to extend a given multi-sensor dataset which contains sparse GPR data. In the first approach, simulated GPR data is generated either by an interpolation along the time axis or by a machine learning model. The second approach includes the simulation of soil-moisture along the GPR profile. The soil-moisture estimation is improved significantly by the fusion of hyperspectral and GPR data. In contrast, the combination of simulated, sensor-like soil-moisture values and hyperspectral data achieves the worst regression performance. In conclusion, the estimation of soil moisture with hyperspectral and GPR data engages further investigations.Comment: This work has been accepted to the IEEE WHISPERS 2018 conference. (C) 2018 IEE

Brains of Prominent People: History, Facts and Significance

In conclusion, in the brains of outstanding right-handed people (Haeckel, Monakow, Pilsudski) the more complicated convolutional and fissural patterns were found on the left hemisphere; in those of outstanding left-handed people (Menzel, Edinger) on the right one. The second brain reported here revealed some overdevelopments on the right, others on the left hemisphere. Strangely enough, very little is known about side-differences in the average brain. It seems that the middle frontal convolution and the inferior parietal lobe are more developed on the right hemisphere, the inferior frontal convolution on the left one. Nothing is known about the handedness of the bearers of brains showing these side-differences
