Our production and consumption patterns of electronic products exceed the limits of what one planet can handle. Prolonging product lifetimes decreases the value losses caused by the destruction of existing products and lowers the amount of e-waste. Repair is an impactful strategy to tackle the issues associated with the production and...

Schelbergen, M. (author)
The potential of utility-scale airborne wind energy (AWE) systems to contribute significantly to the energy transition hinges on their large-scale deployment, which depends on the cost-competitiveness and complementarity with conventional wind turbines. Central to the assessment of these metrics is understanding long-term energy production,...

The aeronautical sector faces challenges in meeting its net-zero ambition by 2050. To achieve this target, much effort has been devoted to exploring sustainable aviation fuels (SAF). Accordingly, we evaluated the technical performance of potential SAF production in an integrated first- and second-generation sugarcane biorefinery focusing on...

Microgels are cross-linked, colloidal polymer networks with great potential for stimuli-response release in drug-delivery applications, as their small size allows them to pass human cell boundaries. For applications with specified requirements regarding size, producing tailored microgels in a continuous flow reactor is advantageous because...

The heat capacity of technetium metal has been measured from 2.1 K to 293 K using relaxation calorimetry and the enthalpy increment up to 1700 K using drop calorimetry. The low-temperature calorimetry measurements revealed a superconducting transition temperature of T<sub>C</sub> = (7.76 ± 0.08) K. The zero-degree Debye temperature(θ<sub>E<...

We formulate standard and multilevel Monte Carlo methods for the kth moment M<sub>ε</sub><sup>k</sup>[ξ] of a Banach space valued random variable ξ:Ω→E, interpreted as an element of the k-fold injective tensor product space ⊗<sub>ε</sub><sup>k</sup>E. For the standard Monte Carlo estimator of M<sub>ε</sub><sup>k</sup>[ξ], we prove the k...

For a simple graph Γ and for unital C<sup>*</sup>-algebras with GNS-faithful states (A<sub>v</sub>,φ<sub>v</sub>) for v∈VΓ, we consider the reduced graph product (A,φ)=⁎<sub>v,Γ</sub>(A<sub>v</sub>,φ<sub>v</sub>), and show that if every C<sup>*</sup>-algebra A<sub>v</sub> has the completely contractive approximation property (CCAP) and...

A biokinetic model based on BioWin's Activated Sludge Digestion Model (ASDM) coupled with a nitrous oxide (N<sub>2</sub>O) model was setup and calibrated for a full-scale wastewater treatment plant (WWTP) Amsterdam West, in the Netherlands. The model was calibrated using one year of continuous data to predict the seasonal variations of N<sub...

In the long-term mining of geothermal resources in hot dry rock (HDR), the change of thermal stress and pore pressure will increase fracture conductivity evolution, further improving production performance. The optimization and decision-making of the development scheme based on the impact of damage from fractures have yet to be reported. The...

A dual-growth-limited continuous operated bioreactor (chemostat) was used to enhance lipid accumulation in an enrichment culture of microalgae. The light intensity and nitrogen concentration where both limiting factors resulting in high lipid accumulation in the mixed culture. Both conditions of light and nitrogen excess and deficiency were...

Sensor data and agro-hydrological modeling have been combined to improve irrigation management. Crop water models simulating crop growth and production in response to the soil-water environment need to be parsimonious in terms of structure, inputs and parameters to be applied in data scarce regions. Irrigation management using soil moisture...

The design of bespoke adaptive detection schemes relying on the joint use of multistatic/polarimetric measurements requires a preliminary statistical inference on the clutter interference environment. This is of paramount importance to develop an analytic model for the received signal samples, which is mandatory for the synthesis of radar...

Subjective scales are frequently used in the design process of head-related products to assess pressure discomfort. Nevertheless, some users lack fundamental cognitive and motor abilities (e.g., paralyzed patients). Therefore, it is vital to find non-verbal measurements of pressure discomfort and pressure pain. This study gathered the autonomic...

The synthesis of N-A-S-H gel with high Si/Al ratios (&gt;2) has been rarely reported in the literature, leaving the establishment of a reliable synthesis route as an open challenge. This paper aims to synthesize N-A-S-H gels with Si/Al ratios ranging from 1 to 3 and establish their thermodynamic database. The effects of reaction temperature,...

Despite their environmental benefits, products made from recycled materials are not readily adopted. Prior studies focused on improving consumer adoption via product attributes and marketing elements, but the impact of product appearance remains a gap in the literature. This research contributes by investigating how observability of the recycled...
