We prove that the SD-prenucleolus satisfies monotonicity in the class of convex games. The SD-prenucleolus is thus the only known continuous core concept that satisfies monotonicity for convex games. We also prove that for convex games the SD-prenucleolus and the SD-prekernel coincide.

In 1972, Maschler, Peleg and Shapley proved that in the class of convex the nucleolus and the kernel coincide. The only aim of this note is to provide a shorter, alternative proof of this result.

This paper studies an allocation procedure for coalitional games with veto players. The procedure is similar to the one presented by Dagan et al. (1997) for bankruptcy problems. According to it, a player, the proposer, makes a proposal that the remaining players must accept or reject, and con...

In a recent paper Leong-Huang:2010 {Journal of Applied Statistics 37, 215Ӳ33} proposed a wavelet-correlation-based approach to test for cointegration between two time series. However, correlation and cointegration are two different concepts even when wavelet analysis is used. It is known that...

The article presents the main design features and photovoltaic requirements of a FPCS (floating photovoltaic cover system) for water irrigation reservoirs whose purpose is to reduce the evaporation of water while generating electrical power. Also, a summary of installation costs and relationship...

The present paper aims to describe the experimental study developed to characterise an indirect evaporative cooling system made of polycarbonate, designed and manufactured by the Thermal Engineering Group of the University of Valladolid; as well as to introduce the main results obtained.

In this paper, changes in the Spanish personal income distribution along the period 1973-2000 are studied using the parameter estimations of the Dagum model for the state and its autonomous communities. With this aim, in the first place, a theoretical approach to the parameters of Dagum model is...
