A Survey of Crowdsourcing Methods for Commonsense Knowledge Collection

Commonsense knowledge is information that all humans own and use to interpret common situations and react to them accordingly. This kind of information is necessary for the training of artificial intelligence models to reach a performance as close as possible to human performance. Researchers have developed methods that use crowdsourcing to...

Individual versus Typical: The hidden definition of quality in the Deutscher Werkbund

At the turn of the 20th century in Germany, industrialisation led to a disconnect between the artist and their product. In response to the fears of cultural decay, the Deutscher Werkbund, an association of artists and craftsmen, was established in 1907. While its goal was to improve the quality of German design, it never officially defined the...

The potential impact of hydrodynamic leveling on the quality of the European vertical reference frame

The first objective of this paper is to assess by means of geodetic network analyses the impact of adding model-based hydrodynamic leveling data to the Unified European Leveling Network (UELN) data on the precision and reliability of the European Vertical Reference Frame (EVRF). In doing so, we used variance information from the latest UELN...

Remote Work Aided by Conversational Agents

Due to the coronavirus pandemic, remote work from home has rapidly become a necessity around the world, drastically changing the potential landscape for the future of work. Over the last couple of decades, microtask crowdsourcing has emerged as a viable means of carrying out remote online work to earn one’s living — an alternative to traditional...

A probabilistic analysis of results of co-registration of aerial and mobile laser-scanned point clouds

Over the last decades, laser scanners are becoming more and more established for the acquisition of geo-information. Depending on the sensor platform where the laser scanners are mounted, there are MLS, ALS and TLS techniques for both indoor and outdoor environments. The high-quality 3D point clouds produced from laser scanners is an important...

Towards Automated Test Case Generation Maturity

This short paper reports our observations after six editions of the JUnitContest that benchmarks automated unit test generation tools for Java programs. We discuss our experience and depict the current state-of-the-art and identify potential future research directions. We advocate the use of benchmark as a standard practice to enhance maturity...

Modelling in the service of sustainable construction

The world’s infrastructure is vital for providing accommodation and mobility for people. Although it is obvious that the construction industry has been crucial for realizing building and civil infrastructures, it is also clear that building activities have a big impact on the environment. Still growing and developing societies and economies...

Quality of the integral aircraft engine MRO chain: A case study on the Low and High Pressure Compressors at KLM Engineering & Maintenance Engine Services

This research presents a model to estimate the influence of the variance of the quality of repair steps on the EGT Margin within the serviceable limits of the overhauled modules. This model is created using literature and a single case study conducted at KLM Engineering & Maintenance Engine services (KLM E&M ES). The model is tested...

Quality assessment of airline baggage handling systems using SERVQUAL and BWM

The baggage handling system is a crucial part of ground handling operations, which significantly contributes to the overall satisfaction of passengers. Although several studies have investigated airline service quality, little attention has been paid to this crucial part of the system. This study proposes the SERVQUAL model to assess the...

How models can make a difference for a sustainable future of the building industry

Models play a vital role in science and technology and in the evolution of modern societies. They are used for describing processes and mechanisms, experimental observations, analyses and predictions. In spite of the fact that models are a reduction of reality, the achievements of modern societies are impressive and would have been...

Level of detail in 3D city models

The concept of level of detail (LOD) describes the content of 3D city models and it plays an essential role during their life cycle. On one hand it comes akin to the concepts of scale in cartography and LOD in computer graphics, on the other hand it is a standalone concept that requires attention. LOD has an influence on tendering and...

The ISPRS benchmark on indoor modelling

Automated generation of 3D indoor models from point cloud data has been a topic of intensive research in recent years. While results on various datasets have been reported in literature, a comparison of the performance of different methods has not been possible due to the lack of benchmark datasets and a common evaluation framework. The ISPRS...

Connecting with customers: A service for RIKILT Laboratory Quality Service

The world population is increasing and ageing. This causes an increasing demand for healthy and protein-rich food, putting pressure on food producers to increase their volumes. Sometimes this goes at costs of quality, or even safety. As a result more food safety incidents occur. Therefore the control of food and feed safety and quality is very...

Business Process Quality Computation: Computing Non-Functional Requirements to Improve Business Processes

Business process modelling is an important part of system design. When designing or redesigning a business process, stakeholders specify, negotiate, and agree on business requirements to be satisfied, including non-functional requirements that concern the quality of the business process. This thesis addresses the question of how to specify and...

Analysis of Risk Management Activities in the Design, Engineering, Development phases of Manufacturing Organizations

New Product or System development in a manufacturing industry is realized through the culminated efforts of different functional units, namely the Research and Development unit, the Supply Chain unit, the Design and Engineering Team, and finally the Manufacturing and Assembly units. The Design, Engineering and Development phase is a critical...

How to build a good practice software project portfolio?

What can we learn from historic data that is collected in three software companies that on a daily basis had to cope with highly complex project portfolios? In this paper we analyze a large dataset, containing 352 finalized software engineering projects, with the goal to discover what factors affect software project performance, and what...
