A continuum model for carbonation curing of fibre-cement composites

Accelerated carbonation curing of cellulose fiber-cement composites is known to improve their durability in the form of decreased porosity and increased mechanical properties. In addition, because carbonation results in a decrease in the alkalinity of cement paste, it makes cement less aggressive towards the cellulose fibers. The properties of...

Numerical Study Of Pier-Wall Connections In Typical Dutch Urm Buildings

In recent years, the seismic risk in the north of the Netherlands has increased due to gas extraction. Since 2014, the Delft University of Technology started a research program to assess the seismic response of unreinforced masonry (URM) buildings. The Dutch URM buildings are characterized by slender piers and transverse walls. In common...

Co-simulation of energy transition in residential sectors of Chinese lower-tier cities

China is undergoing large changes to tackle carbon dioxide emissions and air pollution. While the top-down governance allows for clear setting of emission reduction targets for industrial sectors and major cities, reducing emissions in residential sectors in smaller (the so-called low-tier) cities remain challenging and often unaddressed. This...

Impact of Modelling Assumptions on the Voltage Stability Assessment of Active Distribution Grids

Renewable energy sources (RES) penetrate power grids at all voltage levels. A large number of RES units are connected to medium-voltage (MV) and low-voltage (LV) levels resulting in a significant share of overall generation. Therefore, the dynamic behavior of such distribution grids should be thoroughly examined. The goal of this paper is to...

Perceptual relational attributes: Navigating and discovering shared perspectives from user-generated reviews

Effectively modelling and querying experience items like movies, books, or games in databases is challenging because these items are better described by their resulting user experience or perceived properties than by factual attributes. However, such information is often subjective, disputed, or unclear. Thus, social judgments like comments,...

A Piece-wise Linearized Transformer Winding Model for the Analysis of Internal Voltage Propagation

In this paper, a piece-wise linearized transformer winding model is proposed for transient internal voltage distribution computations. In particular, the model is based on the linearization of the primitive non-linear, frequency dependent and invariant matrix of voltage distribution factors. This primitive matrix is utilized as a pattern from...

Object Tracking in Images of an Airborne Wide Angle FMCW Radar

Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...

3D Cadastres Best Practices, Chapter 5: Visualization and New Opportunities

This paper proposes a discussion on opportunities offered by 3D visualization to improve the understanding and the analysis of cadastre data. It first introduce the rationale of having 3D visualization functionalities in the context of cadastre applications. Second the publication outline some basic concepts in 3D visualization. This section...

Subscript-Based Geospatial Migration Dynamics

Between 2013 and 2015, over one million migrants entered Europe. Many European countries were unprepared for and overwhelmed by the rapidly unfolding, chaotic situation. To better handle future migration waves, and allow quicker exploration of government policy effects and interactions, a geospatial-based system dynamics model of migration flows...

3D Strata Objects Registration for Malaysia within the LADM Framework

This paper discusses 3D objects registration and modelling for cadastral objects within the Land Administration Domain Model (LADM) framework. A conceptual model as well as the associated technical model for the 2D and 3D objects have been proposed and developed for Malaysia. For both private and public land, the main subdivision of land in...

Numerical modelling of forces, stresses and breakages of concrete armour units

Numerical modelling has the potential to probe the complexity of the interacting physics of rubble mound armour systems. Through forward modelling of armour unit packs, stochastic variables such as unit displacement and maximum contact force per unit during an external oscillatory disturbance can be predicted. The combined finite-discrete...
