This paper reports on the corrosion performance of composite zinc layers (~ 8µm) on a steel substrate, considering the influence of nano-aggregates and Cr(III) conversion layers, compared to control (only Zn layers) conditions. The main factors, influencing the corrosion performance of Zn in this study are: a) the effect of two concentrations of...

Bij het werken aan historische tuinen heeft de landschapsarchitect niet alleen te maken met de vele tijdslagen die een ontwerp hebben veranderd in wat het nu is – ook andere disciplines spreken zich uit over de waarde en waardevolle elementen die er in voorkomen. Dat leidt tot soms starre voorschriften die de objecten geen goed doen. Een...

Formation flying is introduced as a new and innovative air transportation system for long-haul commercial flight. With this paper the operational feasibility of formation flying is addressed, both from a market demand and economic, as well as an air traffic control perspective. Preliminary results of a case study indicate that operating a newly...

The airline industry is under continuous pressure to reduce emissions and costs. This paper investigates the feasibility for commercial airlines to use formation flight to reduce emissions and fuel burn. To fly in formation, an aircraft needs to benefit from the wake vortices of the preceding aircraft. This requires a stable aerodynamic flow,...

The term genius loci—“the prevailing character or atmosphere of a place,” as the Oxford English Dictionary defines it—has long been used to interpret landscape characteristics. Lately, however, it is being used, and abused, as a justification in just about any discourse. For spatial, aesthetic, and ecological discussions and social, cultural,...

This study presents the results on the investigation of the corrosion behavior of carbon steel in model alkaline medium in the presence of very low concentration of polymeric nanoaggregates [0.0024 wt % polyethylene oxide (PEO)113-b-PS70 micelles]. The steel electrodes were investigated in chloride free and chloride-containing cement extracts....

This work reports on the electrochemical performance of low-carbon steel electrodes in model alkaline solutions in the presence of 4.9.10-4 g/l hybrid aggregates i.e. cement extract, containing PDADMAC (poly (diallyl, dimethyl ammonium chloride) / PAA (Poly (acrylic acid)/ PDADMAC over a CaO core. The main objective was to determine if the...

This work reports on monitoring chloride-induced corrosion in reinforced mortar specimens, with and without addition of polymeric nano-aggregates in the mortar mixture. The investigation is a novel approach to control steel corrosion in reinforced concrete, hereby reporting the preliminary results, related to one of the main objectives: studying...

This study presents the results from a preliminary investigation on the corrosion behavior of low carbon steel in cement extract (CE) in the presence of very low concentration polymeric nanoaggregates (PEO113-b-PS70 micelles). The steel electrodes were investigated in Cl--containing CE as corrosion medium, compared to chloride-free CE as a...

This work presents the preliminary tests on the performance of cathodic prevention (CPre) in reinforced mortar, subjected to aggressive (10% NaCl environment). Cathodic prevention is an electrochemical technique for minimizing, actually "preventing" any eventual corrosion of the steel bars in reinforced concrete. Therefore, the main objective of...

The evacuation clearance time is one of the key indicators in an evacuation plan and is determined by the expected behavior of the endangered residents and roadway network characteristics. The city of Almere has developed an evacuation plan in case of the emergency of a flooding, but assumes a normal driving behavior of the evacuees. In this...

Paper accepted for publication in the proceedings of the 25th International Conference on Software Maintenance (ICSM 2009). Code cloning is widely recognized as a threat to the maintainability of source code. As such, many clone detection and removal strategies have been proposed. However, some clones can often not be removed easily so other...

The Dutch delta is a reclamation landscape. It has undergone several transformations since the Middle Ages to become an inhabitable, beautiful and unique cultural landscape. Many factors that determine the spatial quality of the future urban landscape are directly connected with the formal properties of the polder landscape of the Dutch lowlands...

Complex systems, such as those encountered in aerospace engineering, can typically be considered as a hierarchy of individual coupled elements. This hierarchy is reflected in the analysis techniques that are used to analyze the physcial characteristics of the system. Consequently, a hierarchy of coupled models is to be used, accounting for...
