MHACO: A Multi-Objective Hypervolume-Based Ant Colony Optimizer for Space Trajectory Optimization

In this paper, we combine the concepts of hyper-volume, ant colony optimization and nondominated sorting to develop a novel multi-objective ant colony optimizer for global space trajectory optimization. In particular, this algorithm is first tested on three space trajectory bi-objective test problems: an Earth-Mars transfer, an Earth-Venus...

Convergence of ant colony multi-agent swarms

Ant Colony algorithms are a set of biologically inspired algorithms used commonly to solve distributed optimization problems. Convergence has been proven in the context of optimization processes, but these proofs are not applicable in the framework of robotic control. In order to use Ant Colony algorithms to control robotic swarms, we present...

Damage resistance of dispersed-ply laminates

This paper presents the design procedure of a quasi-isotropic (QI) laminate employing dispersion of ply orientations. The goal is to improve damage resistance of a laminate under low velocity impact (LVI). The LVI is treated as a quasi-static loading and instead of a plate a laminated beam is considered. Therefore, this situation simplifies the...

On infrastructure network design with agent-based modelling

We have developed an agent-based model to optimize green-field network design in an industrial area. We aim to capture some of the deep uncertainties surrounding infrastructure design by modelling it developing specific ant colony optimizations. Hence, we propose a variety of extensions to our existing work, first ideas on how to realize them...

A repository for sources about European colonial architecture and town planning (c.1850-1970): Creating a digital tool for transnational research

Building a repository on European colonial architecture and town planning

During the past two years the TU Delft Library has developed a repository to store data about architecture and town planning in the former Dutch colonies. Historical images, books, journals and archives coming from libraries and museums are scanned and stored into the repository. Information about architects, buildings and town plans and...

Reciclagem do Grande Hotel Beira Mozambique: An open building intervention for socio-economic empowerment in Mozambique

Poor economies find themselves in an almost no-win situation: They would benefit from improving the economic situations of the very poor by making them self-supporting and economically productive. However, the very poor are occupied by daily survival and thus cannot afford themselves to improve. This paper describes the status quo of a...

A generic method to optimize instructions for the control of evacuations

A method is described to develop a set of optimal instructions to evacuate by car the population of a region threatened by a hazard. By giving these instructions to the evacuees, traffic conditions and therefore the evacuation efficiency can be optimized. The instructions, containing a departure time, a destination, and a route, are created...
