Basic education plays a crucial role in uplifting disadvantaged areas from the grip of poverty. Distance learning systems are a promising option to deliver education to children who have access to none today. The main problem with the large scale deployment of such systems is either their reliance on broadband network access or their lack of interaction among students and teachers. This paper d...

The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...

When investigating the constancy of visual speed J. F. Brown 2 discovered what he called the transposition principle of velocity. In his account the constancy of visual speed and the principle of transposition occur as unrelated facts. This paper attempts to show that constancy of visual speed can be understood as a consequence of the transposition principle. When objects which move with the sa...

The space interferometer LISA will detect the gravitational wave (GW) signal from the inspiral, plunge and ringdown phases of massive black hole binary mergers at cosmological distances. From the inspiral waves, we will be able to measure the masses of the binaries’ members; from the ringdown waves, we will be able to measure the mass of the final merged remnant. A subset of detected events all...

Space-born gravitational-wave interferometers such as LISA will detect the gravitational wave (GW) signal from the inspiral, plunge and ringdown phases of massive black hole binary mergers at cosmological distances. From the inspiral waves, we will be able to measure the masses of the binaries’ members; from the ringdown waves, we will be able to measure the mass of the final merged remnant. A ...
