Ontology alignment: Simulated annealing-based system, statistical evaluation, and application to logistics interoperability

The primary motivation of this dissertation is to investigate how to enable interoperability in the logistics domain by the aid of ontology alignment. More in detail, the primary research objective of this dissertation is To address interoperability between heterogeneous IT systems in logistics by using ontology alignment. To accomplish the...

Impact of DC Voltage Enhancement on Partial Discharges in Medium Voltage Cables: An Empirical Study with Defects at Semicon-Dielectric Interface

A scientific consensus is emerging on the benefits of direct current (DC) distribution in medium voltage (MV) power systems of ships and cities. At least 50% space savings and increased power transfer capacity are estimated with enhanced voltage DC operation of electric cables. The goal of this research is to contribute to developing the...

Interpolation in Time Series: An Introductive Overview of Existing Methods, Their Performance Criteria and Uncertainty Assessment

A thorough review has been performed on interpolation methods to fill gaps in time-series, efficiency criteria, and uncertainty quantifications. On one hand, there are numerous available methods: interpolation, regression, autoregressive, machine learning methods, etc. On the other hand, there are many methods and criteria to estimate...

Study on Governance of Urban Renewal in the UK, Hong Kong and China: the Way to Sustainability

China’s fast growth of economy and urbanization has created a world record on its own since its reform and opening-up policy in late 1970s. This drives mass demolition and reconstruction and leaves a short lifespan of existing buildings through unsustainable urban renewal. Many developed countries/regions, such as the UK and Hong Kong, have long...

Spatial planning and urban resilience in the context of flood risk: A comparative study of Kaohsiung, Tainan and Rotterdam

Spatial planning is increasingly being considered as an important mechanism in coping with flood risk due to climate change. One of the reasons for this is that engineering approaches are increasingly expensive and cannot provide complete certainty of protection against climate-related floods. The thesis examines whether and how spatial planning...

Swedish 3D Property in an International Comparison

The aim of the paper is to present the Swedish types of 3D property, how they are designed and related to each other, and to make a comparison with other types of 3D property that can be found internationally. The Swedish 3D property system is presented and compared with the international standard types of 3D property. In this comparison...

Assessment of the homogeneity of volunteered geographic information in South Africa

The potential for volunteer groups to contribute geographic data to National Mapping Agencies has been widely recognised. Several investigations have been done to determine the geometric accuracy of this data for the purposes of national mapping. Beyond accuracy, from a production perspective National Mapping Agencies will also be interested in...

Supply chain integration in the building industry: The emergence of integrated and repetitive strategies in a fragmented and project-driven industry

The building industry is a fragmented and project-driven industry with specific characteristics, which can sometimes result in negative effects. Reference has often been made to other industries, particularly manufacturing, that would function more effectively and efficiently. Major differences between both include the organisation and...

Using the private rented sector as a form of social housing

The paper considers the role of the private rented sector in supplying housing that can be defined as social housing. It will do this by considering policy initiatives in Germany, France, the USA and England that use privately owned housing to meet social needs. The operation of these initiatives will be compared. The allocation and rent...

Innovative governance of sustainable urban development: A comparative analysis

More than half of the world population lives in urban areas concentrating and increasing the magnitude of social and environmental impacts. The potential role of cities in a transition to a sustainable society started to be widely recognized after the 1992 Rio conference where the Agenda 21 program was signed. Since then, a number of urban...

THE EFFECT OF DYNAMIC LOAD ON FUEL CONSUMPTION AND EXHAUST EMISSIONS OF TSHD DURING DREDGING PROCESS

On the comparison of audio fingerprints for extracting quality parameters of compressed audio

Audio fingerprints can be seen as hashes of the perceptual content of an audio excerpt. Applications include linking metadata to unlabeled audio, watermark support, and broadcast monitoring. Existing systems identify a song by comparing its fingerprint to pre-computed fingerprints in a database. Small changes of the audio induce small...

Comparison of 5 oil-weathering models

Within the project CALPREA at RIKZ application of reliable oil spill models and oil data bases is an important issue. An oil spill model contains in general a transport module, an oil weathering module, an oil data base, and possibly a user-friendly graphical user interface. Recently, de Jong (2004) has made a study of four particle models for...

A Comparison of Four Particle Models: A Comparison of DemWaq, DREAM, GNOME and SIMPAR

This reports presents the results of a comparative study of the following four particle/fate models: 1. DemWaq, developed by RIKZ 2. DREAM, developed by Sintef (Norway) 3. GNOME, developed by NOAA (US) 4. SIMPAR, developed by RIKZ The aim was to find a suitable operational fate model to predict the behavior and distribution of calamitous spills...

Sustainable housing in Europe

There is considerable variation in the extent to which environmental measures are adopted in housing construction in various European countries. Whereas sustainable housing is dearly part of day-to-day building practice in some countries, in others the topic seldom receives serious attention. None of the environmental measures which are...
