Crystallization in suspensions of hard spheres: a Monte Carlo and molecular dynamics simulation study
2011
The crystallization of a metastable melt is one of the most important non-equilibrium phenomena in condensed matter physics, and hard sphere colloidal model systems have been used for several decades to investigate this process by experimental observation and computer simulation. Nevertheless, there is still an unexplained discrepancy between the simulation data and experimental nucleation rate densities. In this paper we examine the nucleation process in hard spheres using molecular dynamics and Monte Carlo simulation. We show that the crystallization process is mediated by precursors of low orientational bond-order and that our simulation data fairly match the experimental data sets.
Hiding in plain view: Colloidal self-assembly from polydisperse populations.
2016
We report small-angle x-ray scattering (SAXS) experiments on aqueous dispersions of colloidal silica with a broad monomodal size distribution (polydispersity 18%, size 8 nm). Over a range of volume fractions the silica particles segregate to build first one, then two distinct sets of colloidal crystals. These dispersions thus demonstrate fractional crystallization and multiple-phase (bcc, Laves AB$_2$, liquid) coexistence. Their remarkable ability to build complex crystal structures from a polydisperse population originates from the intermediate-range nature of interparticle forces, and suggests routes for designing self-assembling colloidal crystals from the bottom-up.
Depletion-induced percolation in networks of nanorods.
2006
Above a certain density threshold, suspensions of rod-like colloidal particles form system-spanning networks. Using Monte Carlo simulations, we investigate how the depletion forces caused by spherical particles affect these networks in isotropic suspensions of rods. Although the depletion forces are strongly anisotropic and favor alignment of the rods, the percolation threshold of the rods decreases significantly. The relative size of the effect increases with the aspect ratio of the rods. The structural changes induced in the suspension by the depletant are characterized in detail and the system is compared to an ideal fluid of freely interpenetrable rods.

How does an allowance for a non-working younger partner affect the retirement behaviour of couples?
2021
AbstractWe examine the effect of the partner allowance (PA) in the Dutch pension system on the retirement decisions of couples using administrative data. PA was paid to people who receive the public old-age pension with a partner younger than the state pension age (SPA) and with a low own income. PA worked as a financial incentive to retire earlier, especially for the younger partners. As of 1 April 2015, new old-age pensioners are no longer entitled to this allowance. We estimate the effect of this reform on the retirement behaviour of each spouse. To account for the fact that at the same time, another reform essentially put an end to generous early retirement arrangements, we compare sing…
Static output-feedback controller design for vehicle suspensions: an effective two-step computational approach
2014
In this study, a novel two-step methodology is applied in designing static output-feedback controllers for a class of vehicle suspension systems. Following this approach, an effective synthesis of static output-feedback controllers can be carried out by solving two consecutive linear matrix inequality optimisation problems. To illustrate the main features of the proposed design strategy, two different static output-feedback H 8 controllers are designed for a quarter-car suspension system. The first of those controllers uses the suspension deflection and the sprung mass velocity as feedback information, whereas the second one only requires the sprung mass velocity to compute the control acti…
Notional defined contribution pension schemes: Why does only Sweden distribute the survivor dividend?
2015
The aim of this paper is to analyse the role of the survivor dividend in notional defined contribution (NDC) pension schemes. At present, this feature can only be found in the Swedish defined contribution scheme. We develop a model that endorses the idea that the survivor dividend has a strong basis for enabling the NDC scheme to achieve financial equilibrium and that not including the dividend is a non-transparent way of compensating for increases in longevity and/or legacy costs from old pension systems. We also find that the average effect of the dividend remains unchanged for any constant annual rate of population growth, that contribu-tors who reach retirement age always get a higher r…
Influence of pillar 3 of pension system on retirement pensions level in Poland : will voluntary part of system enable decent life in old age?
2021
PURPOSE: The aim of this paper is the comparative analysis of the general saving ways included in pillar 3 of the pension system and showing their potential effectiveness from the perspective of the pension system participant. Will the resources allocated by the instruments of the voluntary pension system part significantly improve the level of the future pension? Will they allow a more decent life for an average Polish citizen in the period of the old age?

Prestacions no contributives
2020
El document exposa les pensions no contributives de jubilació i invalidesa. Al estar concebudes per a persones amb situació de manca de recursos que no complixen els requisits per accedir a pensions de la Seguretat Social en règim contributiu, s'expliquen els requisits d'acces i les incompatibilitats amb altres prestacions i subsidis propies del sistema de Serveis Socials. This paper sets out the non-contributory retirement and disability pensions. Being designed for people with a lack of resources who do not have the requirements to access Social Security pensions in the contributory system, the access requirements and incompatibilities with other benefits and subsidies specific to the Soc…
