Linking patterns of physical and chemical organic matter fractions to its lability in sediments of the tidal Elbe river

Degradability of organic matter in river sediments differs in relation to origin and age. In order to explain previously observed spatial patterns of organic matter degradability and stabilization, this study investigated sediment organic matter (SOM) properties along a tidal Elbe river transect using dissolved organic matter (DOM) fractions,...

Microgrid planning based on computational intelligence methods for rural communities: A case study in the José Painecura Mapuche community, Chile

Microgrids (MGs) are sustainable solutions for rural zone electrification that use local renewable resources. However, only careful planning at the start of an MG project can ensure its future optimal operation. In this paper, a novel methodology for MG planning by using the uncertainty characterization of renewable resources and demand is...

Joint Method of Moments (JMoM) and Successive Moment Cancellation (SMC) Multiuser Time Synchronization for ZP-OFDM-Based Waveforms Applicable to Joint Communication and Sensing

It has been recently shown that zero padding (ZP)-orthogonal frequency-division multiplexing (OFDM) is a promising candidate for 6G wireless systems requiring joint communication and sensing. In this paper, we consider a multiuser uplink scenario where users are separated in power domain, i.e., non-orthogonal multiple access (NOMA), and use...

Working towards an AI-­based clustering of airports, in the effort of improving humanitarian disaster preparedness

In the past few years, the frequency of onset natural disaster has been rising, causing significant damage to communities and infrastructure around the world. When it happens, airports in the region affected have to rapidly adjust and evolve from serving regular passengers to becoming a humanitarian hub, that handles a massive surge in both...

Counter the Fast Building Refresh Rate: The Leverhouse as a social office

This graduation project will be focussing on revitalising the CBD North- East Midtown by using the current building stock respectively the Lever House along Park Avenue designed by SOM Architects. This building is also caught by the large migration to Hudson Yards as more than 50 percent of the building is vacant. A planned raise of lease due to...

Design exploration of quantitative performance and geometry typology for indoor arena based on self-organizing map and multi-layered perceptron neural network

During the early design process, simulations allow numeric assessment and 3D models allow visual inspection for qualitative criteria. However, exploring different design alternatives based on both is challenging. To support the design exploration of quantitative performance and geometry typology of various design alternatives during the early...

Design Space Exploration of a Neuromorphic ECG Classification System using a Spiking Self-Organizing Map

The Self-Organizing Map (SOM) is an unsupervised neural networktopology that incorporates competitive learning for the classicationof data. In this thesis we investigate the design space of a system incorporating such a topology based on Spiking Neural Networks (SNNs), and apply it to classifying electrocardiogram (ECG) beats. We present novel...

Integrating the Multi-Functional Space and Long-Span Structure for Sports Arena Design: A design exploration process based on design optimization and self-organizing map

The multi-functional space of sports arena is highly related to the long-span structure. To support the integration of these two aspects, design optimization combining parametric modeling, performance simulations, and searching algorithm can be used. However, optimization is powerful in dealing with quantitative performance, but for some soft...

Load estimation for microgrid planning based on a self-organizing map methodology

This study presents a novel load estimation method for isolated communities that do not receive energy or only receive it for a limited time each day. These profiles have been used to determine the installed capacity of generating units for microgrid electrification projects. The social characteristics and lifestyles of isolated communities...

Narekenen Deltagoot, Minersom ten gevolge van de opgelegde belastingen

Bij het ontwerp van de asfaltbekleding die in 1991 in de Deltagoot is beproefd, bestond het huidige rekenmodel GOLFKLAP nog niet. Er werd gewerkt met een dimensioneringswijze gebaseerd op een lijnlast. Bij de analyse van de metingen zijn indertijd wel golven nagerekend, in die zin dat de gemeten drukken zijn geschematiseerd en met die belasting...

Multidisciplinary design optimization of wing shape with nacelle and pylon

A Multidisciplinary Design Optimization (MDO) system for a wing with nacelle and pylon is developed. The present MDO system is based on the integration of Computational Fluid Dynamics (CFD) codes and NASTRAN based an aeroelastic-structural interface code. The Kriging model is employed to save the computational time of objective function...
