Streamlining river groynes: Laboratory experimentsin schematised geometry under submerged flow conditions

Groynes are hydraulic structures commonly applied in the Dutch rivers. Depending on the water depth, groynes can be emerged or submerged. When a groyne is emerged, it has two main functions: maintaining the water depth in the main channel and preventing the river from eroding its bank. When the discharge in the river increases, the groynes...

Preliminary design of a flood abatement control zone (ZAC) in the region of Murcia, Spain

The coastal area of the Murcia region in Spain experiences more frequent and more intense flash floods caused by inland heavy rainfall due to climate change. This results in high water levels in towns and cities, leading to risk of loss of life and many financial damages. Currently the region is vulnerable, because there are no hydraulic...

Thermodynamic, Transport and Structural Properties of Deep Eutectic Solvent Mixtures Relevant to Capture and Conversion of CO2 to Value Added Products: A Molecular Dynamics Study

The current industrial application of carbon capture utilization and storage (CCUS) is limited due to technological drawbacks such as high energy demand and environmental pollution. Ionic liquids (ILs) and deep eutectic solvents (DESs) are considered promising alternative solvents for the capture of carbon dioxide (CO2). DESs are often...

Westfort Park: a strategy for a community upgrade

The former leprosarium Westfort in South Africa is a very valuable place, but under pressure because of the poor squatters using the institution grounds as living place and the urban sprawl of Pretoria, reaching the borders of the site. A plan for the current community and the heritage structures is needed to secure its future. My plan is based...

From emergency department to acute medical unit: Optimizing the patient experience journey by design

In the medical world the focus is shifting from a clinical perspective towards a user experience perspective. The Leids University Medical Centre has the vision to put the patient central. Therefore in this project the patient experience was optimized by design within the current Integral Patient Logistics Project at the Acute Medical Unit at...

Finding infinitely many even or odd continued fractions by introducing a new family of maps

A new family of continued fractions expansions is introduced by combining two existing family's (2-expansions and flipped expansions). This new family has infinitely many mappings with the property that for every x the digits are only even or only odd. Apart from a whole range of examples, convergence is proved and ergodicity is studied. By...

The influence of biofilm development on the effective gas permeability in hydraulic fractures

Shale gas is natural gas captured in low permeable shale formations, to be able to produce this gas the permeability of the reservoir needs to be enhanced. Hydraulic fracturing is used in low permeable reservoirs to increase the permeability and make gas production possible. Fracking fluid is pumped in the reservoir at high pressure to create...

Wat is de invariante maat van de gegeneraliseerde kettingbreukafbeelding?

In deze scriptie word numeriek de invariante maat gegeven van de gegeneraliseerde kettingbreuk. Resultaten als constante van Khinchine worden vervolgens berekend voor de gegeneraliseerde kettingbreuk. Ook worden convergentie bewijzen gegeven voor zowel de reguliere kettingbreuk als de gegeneraliseerde kettingbreuk. Verdere eigenschappen over de...

Zwembad "De Vosse": Hoe het zwemseizoen te verlengen… …en tóch buiten te kunnen zwemmen?

Zwembad “De Vosse” is een openluchtzwembad in de gemeente Hillegom. Het bad is geopend in de maanden mei, juni, juli en augustus. Bij mooi weer trekt het jaarlijks meer dan 50.000 bezoekers, aangezien het een van de weinige openluchtbaden in de regio is. Voor de exploitatie is het wellicht gunstiger als het bad gedurende een langere periode...
