Earlier studies on the traffic flow on freeways reveal that queue discharge rate cannot
reach as high as the free-flow capacity. This important phenomenon is called the
“Capacity drop”, which indicates that the potential freeway capacity cannot be fully
utilized when discharging traffic jams. Even though a majority of empirical and...

This paper is a follow up to DesignX, a position paper written in 2014, which introduced the design challenges of complex sociotechnical systems such as healthcare, transportation, governmental policy, and environmental protection. We conclude that the major challenges presented by DesignX problems stem not from trying to understand or address...

The aerospace industry is recently expressing a growing interest in green, safe and non-toxic propellants for the propulsion systems of the new generation of space vehicles, which is especially true in the case of Cubesat micro-propulsion systems. Demanding requirements are associated to the future missions and challenges offered by this class...

This work reports on the healing of early stage fatigue damage in ionomer/nano-particulate composites. A series of poly(ethylene-co-methacrylic acid) zinc ionomer/Fe3O4 nanoparticle composites with varying amounts of ionic clusters were developed and subjected to different levels of fatigue loading. The initiated damage was healed upon localized...

The heat storage changes (Qt) can be a significant component of the energy balance in lakes, and it is important to account for Qt for reasonable estimation of evaporation at monthly and finer timescales if the energy balance-based evaporation models are used. However, Qt has been often neglected in many studies due to the lack of required water...

The concept of the General Purpose Technology (GPT) of the late 1990s is a culmination of many evolutionairy views in innovation-thinking. By definition the GPT considers the technical, social, and economic effects of meta-technologies like steam-technology and electric technology. This paper uses Schumpeter’s concept of ’cluster on innovations’...

The unintended economic effect on society as result of individual behaviour —Adam Smith’s ‘Invisible Hand’ of economic progress in the eighteenth century — had its equivalent in technological progress. In the nineteenth century, again individual behaviour with its Acts of Innovation and Acts of Business had an unintended effect. It changed not...

Current Full Range Adaptive Cruise Control (FRACC) systems switch between separate adaptive cruise control and collision avoidance systems. This can lead to jerky responses and discomfort during the transition between the two control modes. We propose a Full Range Adaptive Cruise Control (FRACC) design integrating adaptive cruise control and...

The growth in container volumes over the last decades means an increase in container handling at terminals around the world. Notwithstanding the economic benefits, container handling causes additional pressure on the surrounding infrastructure and the environment. This is happening precisely at a time when environmental issues, in particular CO2...

A new approach for the linearization of governing equations that describe flow and transport in porous media is proposed in this work. It is based on an approximate representation of the exact physics of the problem, which is similar to an approximate representation of space and time discretization performed in conventional simulation. The...

This dissertation consists out of two rather disjoint parts. One part concerns some results on Gaussian harmonic analysis and the other on an optimization problem in optics. In the first part we study the Ornstein–Uhlenbeck process with respect to the Gaussian measure. We focus on two areas. One is on “Gaussian” analogues of classical results in...

Approximations made in traditional day-ahead unit commitment model formulations can result in suboptimal or even infeasible schedules for slow-start units and inaccurate predictions of actual costs and wind curtailment. With increasing wind penetration, these errors will become economically more significant. Here, we consider inaccuracies from...

Estimation problems in the presence of deterministic linear nuisance parameters arise in a variety of fields. To cope with those, three common methods are widely considered: (1) jointly estimating the parameters of interest and the nuisance parameters; (2) projecting out the nuisance parameters; (3) selecting a reference and then taking...

This article explores the use of a System Dynamics model as a boundary object in a case study regarding decision-making on water scarcity in South Africa. The model integrates expertise from the hydrological and ecological sciences with socio-economic information for a specific area, the Mossel Bay region. The model proved to be adaptable to...

Deriving the bed shear stresses from hydrodynamic models in breach models is challenging due to the continuous changing hydraulic head over the breach in combination with horizontal and vertical flow contractions, and the continuous rapidly changing breach geometry. Three stages can be distinguished in breach flows. Stage 1 initiates when the...
