Capacity planning by Network Traffic Prediction

Accurate capacity planning is essential to ensure uninterrupted services and network stability through peak hours for the transport core network of KPN. This involves a trade-off between minimizing the risks of capacity shortages and costs of capacity expansions. High network loads are occurring more frequently and their magnitude is increasing....

Quantifying volume loss from rock penetration in sand during subsea rock installation, using a fallpipe vessel

In the field of offshore engineering, subsea rock installation has emerged as a pivotal technique. As offshore operations extend to greater water depths, the deployment of a versatile fallpipe has become a cornerstone for precise rock particle placement. A comprehensive determination of the overall rock material volume required for installation...

From Human Walking to Bipedal Robot Locomotion: Reflex Inspired Compensation on Expected and Unexpected Downsteps

Humans and other biological bipedal walkers are extraordinarily agile and robust. This is especially apparent when certain features of the environment are unknown such as unexpected downsteps (for example, suddenly walking off the side-walk or not expecting the last stair when descending). Humans can negotiate these downsteps ---both expected...

Design validation and calculation of a self-supporting and foldable solar panel system using FEA

The potential for the production of green energy in the Netherlands is insufficiently utilized. The cause for this problem is the insufficient bearing capacity of industrial roofs for the installation of solar panels using ballast. This required ballast exceeds the bearing capacity of the roof structure, or exceeds the bearing capacity of the...

Spatially explicit WEF modelling in transboundary river basins: A new methodology to study the value of cooperation in regional water management

Water, energy and food resources are fundamental for human survival and are critical for supporting economic development. However, ensuring adequate supply is a major concern for the entire world, specifically in some countries and regions. Under the pressure of population growth, economic development, international trade, urbanization,...

Collective migration and phenotypic plasticity in cancer metastasis: Conflicting views or complementary mechanisms?

Cancer metastasis, the spread of cancer to distant organs, is the major cause of cancerrelated mortality. Hence, understanding the mechanisms underlying cancer metastasis is crucial to improve clinical interventions. Despite intensive efforts, the driving mechanisms remain ill-understood due to the difficulties posed by studying the different...

Analysing residential heating technology trade-offs to influence decision making of municipalities using a GIS-model

The heating transition goals of the Netherlands are ambitious. To reach the goal of an 80% reduction of CO2 emission by 2050, the total residential heat consumption would need to be drastically cut down. The Dutch government is leaning towards implementing large-scale heating networks and reusing waste heat from non-renewable industry. However,...

Business model innovation in European SMEs: thriving configurations and performance implications

For many years, Business Model Innovation (BMI) has been recognized by academics as key to improve competitiveness and innovativeness. While more than ninety percent of the large corporates conduct some degree of BMI, BMI has barely reached Small and Medium enterprises (SMEs). Increasing the use of BMI in SMEs is believed to boost the economic...

Optimization of Non-Planar Wing Aircraft Configurations: Accounting for Low Speed Mission Segments

Air traffic is expected to grow over the next few decades, which will cause the global fuel consumption to increase. Reducing the drag of an aircraft will result in a reduction of the fuel consumption. Non-planar configurations may offer a solution to reduce the drag while maintaining the performance of today’s aircraft. The aim of this study is...

Feasibility study of a novel load alleviation system on the UH-60A Blackhawk helicopter

Formation flight in civil aviation

A model has been developed to demonstrate the value of a decentralized approach to formation flight routing. In the considered scenario, formation flight is an in-flight option. While centralized approaches are well covered in the literature, anticipating the use of formation flight before take-off, decentralized approaches have received less...

Een dokdeur voor Barendrecht

In bouwdok Barendrecht worden sinds 1966 elementen gestort voor afzinktunnels. AI die tijd is voor het openen en sluiten van het dok een deel van het dijklichaam tussen Oude Maas en Bouwdok afgegraven en weer opgebouwd. Deze operatie kost elke keer 3,6 miljoen gulden. Het hier gepresenteerde onderzoek bekijkt de mogelijkheden voor een goedkoper...

Bengkulu Harbour Project

The Indonesian government is stimulating development of areas outside Java to increase the food production of the country and to decrease the population density on Java. Also the Bengkulu district on the west coast of Sumatra has to be developed. Important for development is a good infrastructure, and in an archipelago like Indonesia sea...
