Lighthouses situated on exposed rocky outcrops warn mariners of the dangers that lurk beneath the waves. They were first constructed when approaches to wave loading and structural response were relatively unsophisticated, essentially learning from previous failures. Here, we chart the evolution of lighthouses on the Wolf Rock, situated...

Delirium occurs in upto 80% of the ICU patients and is one of the most common source of morbidity and mortality in the ICU. Inattention is one of the core features of delirium and affects 97% - 100% of the delirium patients. This indicates that attention can be a good parameter for detecting delirium. In literature, it has been found that the...

Nowadays, growing up is quite different from what it was before. Around the globe the larger part of children engage in inordinate time looking at screens (Bucksch et al., 2016). The smartphone enables children to have more screen time, leading to negative consequences. Nevertheless, children still prefer this type of entertainment due to the...

This paper aims to characterize the damage mechanisms of 70 MPa Type IV hydrogen composite pressure vessels using the acoustic emission (AE) method. First, AE signals were captured during the 0–105 MPa and 0–158 MPa hydraulic tests of two vessels using multi-step loading method. Second, the AE feature parameters in time-domain and frequency...

In the Netherlands, the Delta Programme aspires to adjust spatial planning climate-proof and water-resilient, in order to be prepared for extreme weather in 2050. To achieve this ambition, municipalities, provinces, regional water authorities and central governments conduct stress tests to map out the vulnerabilities in their areas of authority...

This thesis studies how serious game developers can develop robust business models with regard to future uncertainties that these developers must be able to deal with. Twelve in-depth interviews were held with managers, owners, and entrepreneurs of serious game developers in the Netherlands to identify and describe in detail the future...

In dit onderzoek zijn twee manieren van A/B-testen met elkaar vergeleken. A/B-testen is het vergelijken van verschillende website versies om te achterhalen welke versie voor een hogere opbrengt zorgt. Consumenten krijgen afzonderlijk meerdere versies van een website te zien: versie A, versie B, versie C, et cetera. De websites verschillen op...

While the world is advancing with taller structures using engineered wood, little importance is being given to natural wood, which is abundantly available in most regions of the world. The lack of technological research using this material in its natural state has caused a drawback in its usage. Also, the dependence on engineered wood for modern...

AE faculty at TU Delft is currently developing a PocketQube satellite under the name of Delfi-PQ. Following the previous study, performed on a high level systems engineering on Delfi-PQ propulsion sub-system, there is a need to verify the propulsion sub-system's design, its final operational envelope values, and propulsion sub-system's...

The thermal cone penetration test (T-CPT) allows in situ measurement of the thermal properties of soil during a CPT-that is without withdrawing the CPT tool and introducing another tool such as a thermal needle probe. An interpretation method is presented based on one-dimensional axisymmetric analytical solutions. Numerical verification of...

Injection Bolts have been preferred for several reasons over other alternatives for the rehabilitation of old riveted steel bridges since 1970’s. More recently they have been used to obtain slip critical shear connections in new structures such as new bridges, large roofs, storm barriers and other structures exposed to cyclic loading. In...

At this time, sensor developers rely on their own circuit board designs to test new sensors. This means a lot of time and money is spent on designing the custom interface for every newly designed sensor. This report describes a way to have a configurable test bench for sensors. The system consists of a data acquisition unit and multiple circuit...

The research of this thesis is focussed on the thermal insulation and structural properties of a thin glass composite panel with 3D-printed polymeric core.<br/><br/>Aluminosilicate glass, used in this research, is only 0,5 mm thick. This aluminosilicate can be used to replace current windows and structural façade element to reduce the use of...

Multi-material compliant mechanisms have shown the potential to be utilized in the upper-limb prosthesis. The mechanisms consist of flexural and rigid parts, where the flexural components can serve as flexible joints between rigid bodies in the device (e.g., finger and finger segments). This configuration is feasible to be fabricated using a...

The world’s climate is changing. In the Netherlands one of the consequences is that water boards and municipalities are preparing for an increase in extreme precipitation. To evaluate the consequences in case of extreme precipitation all Dutch municipalities and water boards have to perform a stress test. In these stress tests the response of...

Photovoltaic (PV) solar energy is variable and not completely predictable; therefore, different energy storage devices have been researched. Among the variety of options, electrochemical cells (commonly called batteries) are technically feasible because of their maturity and stability. However, PV-battery systems face multiple challenges such as...

Additive manufacturing (AM) is currently making a transition from mainly being used for prototyping to an alternative for conventional production methods. AM provides more freedom in design geometry combined with the possibility to produce (complex) products in low quantities. As a result, the need arises for printed parts with consistent...

The dissemination of composite materials introduces applications of hybrid structures with composite and metal parts. The development of reliable methodologies to evaluate the performance of these structures is required. In this work, the mixed-mode fracture behaviour of a bi-material adhesively bonded joint is investigated. A new strain...

The behaviour of square steel tube confined reinforced concrete columns after fire exposure was studied experimentally and numerically in this paper. Eighteen stub columns were first heated following the ISO 834 standard fire including both heating and cooling phases, and were subsequently loaded to failure after cooling to ambient temperature....

Health literacy, i.e. the ability to read and understand medical text, is a relevant component of public health. Unfortunately, many medical texts are hard to grasp by the general population as they are targeted at highly-skilled professionals and use complex language and domain-specific terms. Here, automatic text simplification making text...
