As opposed to the classical voting system (one person one decision one vote) a new voting system is deÞned where agents are endowed with a given number of votes that can be distributed freely between a prearranged number of issues that have to be approved or dismissed. Its essence relies on allowing voters to express the intensity of their preferences in a simple and applicable manner. From a m...

The k-majority game is played with n numbered balls, each coloured with one of two colours. It is given that there are at least k balls of the majority colour, where k is a fixed integer greater than n/2. On each turn the player selects two balls to compare, and it is revealed whether they are of the same colour; the player’s aim is to determine a ball of the majority colour. It has been correc...

Brain stimulation techniques are important in both basic and clinical studies. Majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. Low intensity focused ultrasound (LIFU) seems to be a proper candidate for dealing with such deficiencies. This review recapitulates studies which explored the effects of LIFU on brain str...

Abstract The study of electoral system reform is often focused on consolidated democracies. This special issue reforms in the Mediterranean region selects both democracies and moderate authoritarian systems. It analyses under aspects how they deal with dilemma between improving ‘governability’ by majoritarian instruments versus increasing proportionality representation. While governability also...

In this paper we study space-efficient deterministic population protocols for several variants of the majority problem including plurality consensus. We focus on space efficient majority protocols in populations with an arbitrary number of colours C represented by k-bit labels, where k = dlogCe. In particular, we present asymptotically space-optimal (with respect to the adopted k-bit representa...

The human visual system is able to accurately determine the color of objects irrespective of the spectral power distribution used to illuminate the scene. This ability to compute color constant descriptors is called color constancy. Many different algorithms have been proposed to solve the problem of color constancy. Usually, some assumptions have to be made in order to solve this problem. Algo...
