In cooperative games, a key question is to find a division of payoffs to coalition members in a fair manner. Nucleolus is one of such solution concepts that provides a stable solution for the grand coalition. We study the computation of the nucleolus of a number of cooperative games, including fractional matching games and fractional edge cover games on general weighted graphs, as well as verte...

by approval of building advance-sale act in 2010, it is permitted to sell in advance the buildings to be built in future. in this act, certain rights and obligations are provided for the advance-sellers and advance-buyers. the approval of the said act is a development in the law of sale of buildings. amongst them are the requirement for official registration of any building advance-sale, statut...

Motivated by the need for succinct representations of all “small” transversals (or hitting sets) of a hypergraph of fixed rank, we study the complexity of computing such a representation. Next, the existence of a minimal hitting set of at least a given size arises as a subproblem. We give one algorithm for hypergraphs of any fixed rank, and we largely improve an earlier algorithm (by H. Fernau,...

The cochlea amplifies sound over a wide range of frequencies. Outer hair cells have been thought to play a mechanical part in this amplification, but it has been unclear whether they act rapidly enough. Recent work suggests that outer hair cells can indeed work at frequencies that cover the auditory range.

This paper presents a new approach for implementing an integrating quality, environment and security management system on the basis of three aspects: process-based approach, risk management and a global monitoring system used as integrating factors to satisfy three important levels of integration, namely, correspondence, coordination and integration. The different steps of the proposed approach...

Single fluorescent molecules (represented by spheres with a volume equal to the actual van der Waals volume of the molecule) has been embedded in a polystyrene matrix (left). Such molecules act as probes for the study of polymer nanoscale (segmental scale) dynamics in thin films deposited on a glass cover slide (right).

The advice given?although in some respects applicable more to conditions in America than to those in this country?is therefore based on sound principles and practical experience. To quote from the dust cover, the book "contains 100 real life stories covering every type of situation" within the scope of its special subject, i.e. the problems of married sons and daughters confronted with the nece...

The British government's dealings in Ireland have long been characterised by cover-ups, deceit and perfidiousness. This includes collaboration between British security forces and loyalist paramilitaries, the obstruction of legal investigations, the refusal to hold public enquiries, and the introduction of a new form of intelligence-led policing which, in many cases, allowed informers to act wit...
