This paper describes two open problems in planning and presents preliminary ideas that could lead to potential solutions. The problems on which the paper focuses are (1) combining top-down and bottom-up reasoning to create hierarchical plans, and (2) representing domain knowledge in domains that are unpredictable or too complex to described or reasoned about precisely. The first problem is part...

State security archives in Eastern Europe are shedding new light on the operative practices of secret services and their interaction with performance art. Surveillance, tracking, undermining, disruption, writing reports, measure plans were different methods to be carried out continuous repetitive processes. This paper argues that, through these working processes, state agencies permanently enga...

This paper presents a new methodology based on AHP and ANP (Saaty, 1980, 1996) to estimate the value and transfer fees of professional football players. The paper extends the AHP multicriteria methodology proposed by Moreno-Jiménez et al. (2010) for estimating the value of these sportsmen. The new approach multiplicatively combines the (intrinsic) value of the player (estimated by means of AHP ...

Electoral systems are complex entities composed of a set of phases that form a process to which performance parameters can be associated. One of the key points of every electoral system is represented by the electoral formula that can be characterized by a wide spectrum of properties that, according to Arrow’s Impossibility Theorem and other theoretical results, cannot be all satisfied at the s...

The lattice Boltzmann (LB) method is used to study the kinetics of domain growth of a binary fluid in a number of geometries modeling porous media. Unlike the traditional methods which solve the Cahn-Hilliard equation, the LB method correctly simulates fluid properties, phase segregation, interface dynamics and wetting. Our results, based on lattice sizes of up to 4096× 4096, do not show eviden...

We derive an exact nonlinear nonlocal macroscopic equation for the time evolution of the conserved order parameter rsr, td of a microscopic model binary alloy undergoing phase segregation: a d-dimensional lattice gas evolving via Kawasaki exchange dynamics, satisfying detailed balance for a Hamiltonian with a long range pair potential gdJsgjxjd. The macroscopic evolution is on the spatial scale...

In this paper, we reformulate the diffuse interface model of the tumor growth (S.M. Wise et al., Three-dimensional multispecies nonlinear tumor growth-I: model and numerical method, J. Theor. Biol. 253 (2008) 524--543). In the new proposed model, we use the conservative second-order Allen--Cahn equation with a space--time dependent Lagrange multiplier instead of using the fourth-order Cahn--Hil...

We study the one-dimensional Cahn-Hilliard equation with an additional driving term representing, say, the effect of gravity. We find that the driving field E has an asymmetric effect on the solution for a single stationary domain wall (or ‘kink’), the direction of the field determining whether the analytic solutions found by Leung [J. Stat. Phys. 61, 345 (1990)] are unique. The dynamics of a k...

Studies conducted after the marketing authorisation with the objective of identification, characterization or quantification of one or more risks (called PASS "Post-Authorisation Safety Studies"), have been strengthened in the past years with the implementation of the concept of risk management plans (RMPs), established in 2005 in the European regulatory framework and recently amended as part o...
