Source Term Modeling of Vortex Generators

Vortex generators (VGs) are effectively used to improve the performance of the wind turbine blades by means of flow control. VGs can be represented by local geometrical disturbance on the aerodynamic surfaces. This disturbance generates vortices in the streamwise direction, energizing the boundary layer and hence delaying or suppressing the flow...

Locally go from digital to garments

The maker culture has created a dynamic in which designers are less responsible for the design and quality of the final product, but instead for the tools the consumer uses to create their own. While additive manufacturing (AM) is gaining acceptance among the general public, it is still seen as a prototyping tool instead of a high quality...

Hierarchical clustering in minimum spanning trees

The identification of clusters or communities in complex networks is a reappearing problem. The minimum spanning tree (MST), the tree connecting all nodes with minimum total weight, is regarded as an important transport backbone of the original weighted graph. We hypothesize that the clustering of the MST reveals insight in the hierarchical...

Redefining the role of designers within an urban community using digital design and localized manufacturing of wearables

The maker culture has created a dynamic in which designers are less responsible for the design and quality of the final product, but for the tools the consumer uses to create their own. While additive manufacturing (AM) is gaining acceptance among the general public, it is still seen as a prototyping tool instead of a high quality production...

The Trees and the Forest: Characterization of complex brain networks with minimum spanning trees

In recent years there has been a shift in focus from the study of local, mostly task-related activation to the exploration of the organization and functioning of large-scale structural and functional complex brain networks. Progress in the interdisciplinary field of modern network science has introduced many new concepts, analytical tools and...

Disruption of Functional Brain Networks in Alzheimer’s Disease: What Can We Learn from Graph Spectral Analysis of Resting-State Magnetoencephalography?

In Alzheimer’s disease (AD), structural and functional brain network organization is disturbed. However, many of the present network analysis measures require a priori assumptions and methodological choices that influence outcomes and interpretations. Graph spectral analysis (GSA) is a more direct algebraic method that describes network...

The correlation of metrics in complex networks with applications in functional brain networks

An increasing number of network metrics have been applied in network analysis. If metric relations were known better, we could more effectively characterize networks by a small set of metrics to discover the association between network properties/metrics and network functioning. In this paper, we investigate the linear correlation coefficients...

Emergence of modular structure in a large-scale brain network with interactions between dynamics and connectivity

A network of 32 or 64 connected neural masses, each representing a large population of interacting excitatory and inhibitory neurons and generating an electroencephalography/magnetoencephalography like output signal, was used to demonstrate how an interaction between dynamics and connectivity might explain the emergence of complex network...

Effect of tumor resection on the characteristics of functional brain networks

Brain functioning such as cognitive performance depends on the functional interactions between brain areas, namely, the functional brain networks. The functional brain networks of a group of patients with brain tumors are measured before and after tumor resection. In this work, we perform a weighted network analysis to understand the effect of...

De korrelatieparameter in de twee-dimensionale Rayleigh kansdichtheidsfunctie voor opeenvolgende golfhoogen; een vergelijking van berekeningsmethoden

In de literatuur is een aantal parameters geformuleerd waarmee getracht wordt een relatie te leggen tussen de vorm van het variantiedichtheidsspektrum van de oppervlakteuitwijking en de gegroeptheid van golfhoogten. Een vrij nieuwe parameter die hiervoor gebruikt wordt is een spektrale vormparameter K. Deze parameter is gedefinieerd op basis van...
