Raytracing Mirror Anamorphosis

Mirror anamorphosis is characterised by a distorted projection, where the combination of a mirror and a specific viewpoint lets the observer see the undistorted image. The use of this technique and complex perspective in general has gone from being niche to becoming mainstream. Raytracing poses itself as a solution to solving the math for such...

Opportunities and challenges in the implementation of the knowledge triangle

Resilience of Incident Management in Smart Cities

The grow of urban environments caused many problems in traffic networks. On the roads in and around an urban environment many traffic incidents happen all the time, especially during rush hours or bad weather conditions. To minimize the negative impacts, an incident scene has to be cleared as soon as possible. Additional delay has been caused by...

Fan-out of 2 Triangle Shape Spin Wave Logic Gates

Having multi-output logic gates saves much energy because the same structure can be used to feed multiple inputs of next stage gates simultaneously. This paper proposes novel triangle shape fanout of 2 spin wave Majority and XOR gates; the Majority gate is achieved by phase detection, whereas the XOR gate is achieved by threshold detection. The...

Advancements in Optical Diagnostics for Experimental Aeroelasticity: Benchmarking the cylinder-foil system

Experimental aeroelasticity has been hindered by the intrusivity of measurement equipment and complexity of the experimental setups. Advancements in hardware development have been encouraging optical tracking techniques to replace cross correlation approaches in experimental aerodynamics. However, digital image correlation (DIC) is still the...

Smoothness-Increasing Accuracy-Conserving Filters for Discontinuous Galerkin Solutions over Unstructured Triangular Meshes

The discontinuous Galerkin (DG) method has very quickly found utility in such diverse applications as computational solid mechanics, fluid mechanics, acoustics, and electromagnetics. The DG methodology merely requires weak constraints on the fluxes between elements. This feature provides a flexibility which is difficult to match with...

Stable Spinning Deployment Control of a Triangle Tethered Formation System

The tethered formation system has been widely studied due to its extensive use in aerospace engineering, such as Earth observation, orbital location, and deep space exploration. The deployment of such a multitethered system is a problem because of the oscillations and complex formation maintenance caused by the space tether's elasticity and...

Quadratic splines on quad-tri meshes: Construction and an application to simulations on watertight reconstructions of trimmed surfaces

Given an unstructured mesh consisting of quadrilaterals and triangles (we allow both planar and non-planar meshes of arbitrary topology), we present the construction of quadratic splines of mixed smoothness — C¹ smooth away from the unstructured regions of T and C⁰ smooth otherwise. The splines have several useful B...

Hydrogenated Boron Phosphide THz-Metamaterial-Based Biosensor for Diagnosing COVID-19: A DFT Coupled FEM Study

Recent reports focus on the hydrogenation engineering of monolayer boron phosphide and simultaneously explore its promising applications in nanoelectronics. Coupling density functional theory and finite element method, we investigate the bowtie triangle ring microstructure composed of boron phosphide with hydrogenation based on structural and...

More Continuous Mass-Lumped Triangular Finite Elements

When solving the wave equation with finite elements, mass lumping allows for explicit time stepping, avoiding the cost of a lower-upper decomposition of the large sparse mass matrix. Mass lumping on the reference element amounts to numerical quadrature. The weights should be positive for stable time stepping and preserve numerical accuracy....

Risk based framework for assessing resilience in a complex multi-actor supply chain domain

Risk management frameworks offer excellent tools to identify and manage risks in supply chains. Existing tools can be used to evaluate impacts of countermeasures, however, analysts struggle with modelling how disruptions escalate in complex supply chain systems within a certain amount of time and across several stakeholders. On the contrary, the...

Empowering the next generation: A German wind & solar energy cooperatives business model research

During the last years the Netherlands has seen an expansion of civilian-led energy cooperatives which focus on investments into local renewable energy production, energy efficiency services and electricity sales. Although the Dutch renewable energy cooperative boom continues, many are struggling to find the right earnings model and long-term...

FLASH optimisation in clinical IMPT treatment planning: optimisation and evaluation of stereotactic lung treatment plans with proton transmission beams

Radiotherapy (RT) is an important modality in treatment against cancer. Developments in this modality are necessary for improvement of patient complications and survival. Aside from fractionation and precise irradiation, FLASH radiotherapy could be a third way to significantly increase the therapeutic window of radiotherapy.The FLASH effect is a...

Compressing Digital Illustrative Art for Mobile Games by Means of 2D Triangle Meshes

Many games played on the mobile phone have become large in download size. A significant portion thereof is due to the many textures that are involved. However, many games have art styles that include clean drawings with gradients, solid colors, and hard lines. We observe that these images’ areas may be more efficiently described by interpolating...

Unveiling the essence of the Knowledge Triangle

In order to overcome the innovation gap, the concept of Knowledge Triangle (KT) and Knowledge Triangle Integration (KTI) is gaining interest within national and European policies. It also functions as the cornerstone of the European Institute of Innovation and Technology (EIT), which has a prominent role in Europe’s Horizon2020 strategy to...
