Mingione, Fabio (author)
Reaction wheels are often the main contributor to microvibrations on satellites. These vibrations are a source of pointing errors and therefore need to be limited as much as possible. The miniaturization trend in the space industry and universities fostered the production of very small reaction wheels, suited to Cubesat and PocketQube scales. A...

Enriched finite element methods have gained traction in recent years for modeling problems with material interfaces and cracks. By means of enrichment functions that incorporate a priori behavior about the solution, these methods decouple the finite element (FE) discretization from the geometric configuration of such discontinuities. Taking...

Turbomachinery design is increasingly carried out by means of automated workflows based on high-fidelity physical models and optimization algorithms. The parametrization of the blade geometry is an essential aspect of such workflows because it defines the design space in which an optimal solution can be found. Currently, parametrization...

The digitalization of the product design process has become the new norm in the engineering design with the development of different CAD software, design analyses tools, and rapid prototyping techniques. More holistic approaches in the product design analyses include modeling of the manufacturing technologies and the entire logistics...

The objective of this research is to explore the possibilities in the use of digital twins towards the maintenance and operation of tunnels. This is explored by looking at the end users of the technology, to profile their needs and requirements and consider a digital twin design that focuses on this. This research is the start of a human centred...

Long Range Wide Area Network (LoRaWAN) covers the needs of energy-constrained IoT-devices for operational longevity and extended communication range in a best-effort fashion. However, Lo- RaWAN’s minimalist design cannot handle the traffic from dense deployments with more than a few hundred devices connected to a single gateway, since each LoRa...

Routing design of aircraft Electrical Wiring Interconnection System (EWIS) is time-consuming and error-prone. A solution, which automatically routes the EWIS inside the aircraft Digital MockUp (DMU), has been proposed and presented in the previous publications. The DMU, however, includes over-detailed features, which hardly influence the...

With the global increase in passenger traffic and growing popularity of long-haul routes over the Asia Pacific region and Atlantic Ocean, the possibility for hypersonic transport could become an attractive option to reduce flight time over long distance from 16-20 hours down to around 4-5 hours. In this thesis, a Multi-Disciplinary Optimisation...

This work is a study into the channel throughput produced by a single channel LoRaWAN gateway under various traffic load conditions. The use of CSMA protocols has been proposed in heavy traffic conditions when ALOHA protocol starts to fail. Three network scenarios - Centralized, Distributed and Hybrid were envisioned in which p-CSMA and np-CSMA...

Digitalization helps companies to become more efficient, therefore new developments should be followed closely. One of these developments is the use of 3D models. An increasing amount of information can be processed by the 3D models. This research will look into one of these developments: Model Based Definition. With Model Based Definition (MBD)...

Fugro GeoServices is currently storing their CAD models of the Petrochemical Industry as attributes of 2D lines in a spatial DBMS. This solution works well for web visualization, but not for performing analyses in 3D. The main objective of this graduation project is to create a 3D spatial DBMS with solid CAD geometries as input. The difficulty...

The goal of this thesis is to investigate the effect of digital design media on the design process of the industrial designer, and the designing of physical objects. Thereupon an educational approach to the practice of shaping objects was developed, which integrates theory about creativity, design methodology, and the application of new...

We present the preliminary results of a work in progress which aims to obtain a software system able to automatically generate a set of diverse 3D building models with a medium level of detail, that is, more detailed that a mere parallelepiped, but not as detailed as a complete geometric representation of the building. Each building model is...

Design activity is pervasive as it is increasingly expanding into all sectors and every day it is increasingly difficult to anticipate the often unpredictable changes resulting from new inventions and changes in technology, tools, methods and social customs using current design systems, and at the same time we need to preserve and store...

In this paper we examine the strategies used in 3D modeling for their efficiency. Our study explores the underlying cognitive process that drives design thinking as well the choice of strategies for using specific features in a given CAD software. We take a cognitive task analysis approach to examine our question. Of a total sample of 19...

Although 3D cadastre web map offer benefits to, among others, planning and disaster management application domains, they pose some technical constraints to be implemented using current web technologies. Some technical constraints may include field data processing, data compatibility and browser limitations. One of technical solutions in support...
