Quitting Basic Military Training (BMT) is a problem in the Dutch Armed Forces. Previous research focused on physical factors. Yet, contemporary research focuses on psychosocial characteristics, study skills, and quality of life factors associated with recruits’ intention to quit BMT. We combined several factors to identify the key factors...

Op verzoek van de CvIO is de DM25 rookhandgranaat getest om rough handling tijdens gebruik op de man te simuleren. De resultaten tonen aan dat repeterende Hard Drop belasting (val van +/- 1.5 m op harde ondergrond) kan leiden tot kraken, volledige verwijdering van de veiligheidshefboom en inslag van de slagpin op de ontsteker. Er wordt...

When a droplet is brought in contact with an undercooled surface, it wets the substrate and solidifies at the same time. The interplay between the phase transition effects and the contact-line motion, leading to its arrest, remains poorly understood. Here we reveal the early solidification patterns and dynamics of spreading hexadecane droplets....

Due to natural depletion many mature fields are currently suffering from productivity issues due to halite precipitation in the North Sea. Main actions to prevent or solve this type of scaling issues include increasing flowing pressures (topside choking or velocity strings), but often considered easiest and most economical are fresh water washes...

Definitive screening designs permit the study of many quantitative factors in a few runs more than twice the number of factors. In practical applications, researchers often require a design for m quantitative factors, construct a definitive screening design for more than m factors and drop the superfluous columns. This is done when the number of...

In this study, an impact strength measurement method based on high speed photography, that has been developed for testing porous concrete, was introduced. In the experiments, a drop weight impact test set-up instrumented with a high speed camera was used. The impact strength analyses were conducted using impedance mismatch method, where the wave...

Liquid loading is the mechanism that is associated with increased liquid hold-up and liquid back flow at lower gas flow rates in gas production wells. In laboratory, most liquid loading experiments are performed at fixed gas and liquid rates (mass flow controlled). In the field, the well behavior is a coupled well-reservoir system in which the...

This paper proposes methods for verification of (m, k)-firmness properties of control applications running on a shared TDMA-scheduled processor. We particularly consider dropped samples arising from processor sharing. Based on the available processor budget for any sample that is ready for execution, the Finite-Point (FP) method is proposed for...

In this contribution a model-based analysis of the application of bounded acceleration in traffic flow is considered as a cause for the capacity drop. This is performed in a Lagrangian formulation of the kinematic wave model with general vehicle specific characteristics. Unconstrained overtaking is presumed, which allows a demonstration to be...

We present guidelines for the configuration of industrial scale chromatographic separationof small molecules. We compared the performance of different axial packed beds, chan-neled monoliths and a continuous monolith assuming silica as base material. The calculatedmass transfer rates were used to calculate the height of a theoretical plate (HETP...

Fog is a significant factor affecting the public traffic because visibility is reduced to a large extent. Therefore the determination of optical visibility in fog from radar instruments has received much interest. To observe fog with radar, high frequency bands (millimeter waves) have the best option. A 35 GHz cloud radar at the Cabauw...

This investigation explores the possibilities to reduce the pressure drop of a single-channel micro-evaporator. The availability of micro-technology to create three-dimensional structures at a micro-meter scale opens opportunities to better control process conditions in once-through boilers. However, process miniaturization possesses some...

In this study experiments are conducted on the flow within a horizontal pipe with two closed side branches of equal length. This configuration is referred to as "quasi-cross configuration" as the distance between the two closed side branches is much smaller than the acoustic wavelength of the first acoustic mode. Focus is placed upon...

Emission of solvent and its degradation products from a typical absorption-desorption based Post Combustion CO2 Capture (PCCC) process is inevitable and thus, an area of growing concern. Recently, it has been pointed out that emissions can also occur by means of aerosol droplets. Conventional counter-measures such as a water wash and a demister...

Concomitant crystallization leads to process intensification through the synergistic combination of the partial processes of particle formation and encapsulation within a single process step. Both cooling and electrospray crystallization in multi-component solutions were used to create (sub-)micron sized particles of different crystalline...

Full flexible use of inkjet printhead units in printing systems requires consistent generation of drops with any given volume and velocity at any moment and place desired. True drop-on-demand is currently hampered by physical phenomena in the printhead. These are residual vibrations and crosstalk resulting from conventional jets. This chapter...

Porous concrete is used in many applications that require permeability, noise absorption or thermal insulation. However, its response under dynamic loading is generally not considered. Porous concrete has a characteristic of forming multiple cracks and subsequently fracturing into small fragments when exposed to impact loading. Therefore, with...
