A comparative study of point clouds semantic segmentation using three different neural networks on the railway station dataset

Point cloud data have rich semantic representations and can benefit various applications towards a digital twin. However, they are unordered and anisotropically distributed, thus being unsuitable for a typical Convolutional Neural Networks (CNN) to handle. With the advance of deep learning, several neural networks claim to have solved the...

Monolithic photonic integration technology platform and devices at wavelengths beyond 2 μm for gas spectroscopy applications

In this paper a generic monolithic photonic integration technology platform and tunable laser devices for gas sensing applications at 2 μm will be presented. The basic set of long wavelength optical functions which is fundamental for a generic photonic integration approach is realized using planar, but-joint, active-passive integration on...

Monolithically integrated widely tunable laser source operating at 2 μm

We present a widely tunable extended cavity ring laser operating at 2 μm that is monolithically integrated on an indium phosphide substrate. The photonic integrated circuit is designed and fabricated within a multiproject wafer run using a generic integration technology platform. The laser features an intracavity tuning mechanism based on...

Value Exploration of ‘the Internet of Things’ for Fashion Retail

The market share of physical retailers is in decline as they are having trouble competing with pure online players. Meanwhile, Philips Lighting is looking for solutions that offer more than mere functional light in an increasingly LED-based industry, to give retailers a competitive advantage over their rivals. This project was set out to explore...

Cultural heritage in urban redevelopment projects: A framework to analyse collaborative strategies

Due to technological, economic and spatial developments, various inner-city industrial areas have lost their former use and their original economic value. Many of these areas have elements of cultural-historical value. Preserving this cultural heritage means managing it for the benefit of current and future generations, and –by doing so -...

Efficient remeshing and analysis views for integration of design and analysis

Design and analysis of products are two separate disciplines, nowadays supported by computers, that frequently need to interact. The first is also known as computer-aided design, and is about the complete digital specification of products, in particular their geometry. Analysis is the process of simulating the physical behaviour of a product...

What determines nearshore sandbar response?

Nearshore sandbars appear with various patterns which may change over time. From observations, these changes seem to be related to changes in hydrodynamic conditions, although observed length scales could not be related directly to occurring wave conditions. The current work investigated the role of both the concurrent and previous hydrodynamics...

Coping with uncertainties in the rail sector

A method is developed that deals with uncertainties concerning the possible future train services and to what extent different infrastructure alternatives accommodate these train services. A case study is done for the rail line The Hague - Rotterdam. Amongst other methods, a policy analysis approach, a traffic modeling program and a net present...

Efficient tetrahedral remeshing of feature models for finite element analysis

Finite element analysis is nowadays widely used for product testing. At various moments during the design phase, aspects of the physical behaviour of the product are simulated by performing an analysis of the model. For each analysis, a mesh needs to be created that represents the geometry of the model at that point. In particular during the...
