Reliability of a dike influenced by a building: Development of a probabilistic method for slope stability of a dike containing a building inside the soil profile
No full textIn this research the reliability of dikes are studied that are influenced by the presence of buildings. Along many Dutch dikes (residential) buildings are present. These buildings may influence the reliability of the dike positevely and or negatively. In this study a probabilistic method is developed to determine the influence of a building, located inside the slope of a dike, on the macro stability. The developed method is also applied to a case-study. The method could be used as a first step for an advanced assessment of buildings located inside the soil profile of a dike.Hydraulic Structures & Flood RiskHydraulic EngineeringCivil Engineering and Geoscience

No full text‘The building life cycle in a complex and dynamic multi-stakeholder environment. Increasing the effectiveness of information with the aid of BIM at Amsterdam Airport Schiphol.’ This research is conducted to deepen the practical use of BIM. In the literature it is said that BIM is the new phenomena that will improve multiple defects within the construction sector. One of them is foreseeing the right information at the right place at the right time during the building life cycle. The aim of this research is to investigate if it is possible to optimise the information streams and if the management process within the building life cycle can be improved with the aid of BIM. This research focuses on two aspects; the fist one is the central and dynamic information administration aspect. The second one is the changes to management due to the implementation of this system. The fact that this trend causes the expected changes in practise is a question that can be asked. To find an answer a clear division will be made within this research, the two topics are Information and Management. These two topics are investigated during a test case at Amsterdam Airport Schiphol. Two optimal flowcharts will be generated and compared to give an answer to the main research question. The results will be written down in a manual that describes the manner how to use BIM in the stated environment.Design & Construction ManagementReal Estate & HousingArchitectur

Project Hue: Report and field study on the water related problems and solutions in and around the Cau Hai lagoon and the Tu Hien inlet, Vietnam
No full textThe Tam Giang-Cau Hai lagoon system, lying in the Thua Thien-Hue province in central Vietnam, is affected by a tropical monsoon climate. This among others is the reason the Cau Hai Lagoon area has a long history of floods and other water related problems. Inhabitants are very dependent on the lagoon, as the main sources of income of people living in the region are fishing, agri- and aquaculture. The project goal has been formulated as follows: Finding an economic as well as technical feasible solution to reduce the water related problems, specifically navigability, salt intrusion and floods, in and around the Cau Hai Lagoon and the Tu Hien inlet and thereby improving the economic development of the region. Concerning flood risk, navigability and salt intrusion the inlet stability and size are important aspects. Using an echo sounder the bathymetry of the inlet has been measured. The measured size of the inlet was one of the input parameters for the hydraulic model that has been set up. This basic model of the Cau Hai basin system was made to test some alternative solutions for the Tu Hien inlet. The different solutions were simulated for five different scenarios. These scenarios include average dry season conditions, average wet season conditions and multiple extreme events. The output of the model for the different alternatives was used to rate the alternatives for a couple of criteria in a Multi Criteria Analysis. Other criteria of the MCA are qualitatively rated. The most promising alternative proved to be the one including a jetty at the northern side of the Tu Hien inlet in combination with a bank protection at the other side. In this way a large part of the littoral drift is blocked, enlarging the equilibrium cross-section of the inlet. This in turn results in a better flood evacuation capacity, navigability and water quality in the lagoon. For both mentioned elements a preliminary technical design is made, resulting in the stone class needed for the armour layers, dimensions of the toe and characteristics of the filter.Hydraulic EngineeringCivil Engineering and Geoscience
Structure – Property relationships for nanofluids
No full textThis paper was presented at the 3rd Micro and Nano Flows Conference (MNF2011), which was held at the Makedonia Palace Hotel, Thessaloniki in Greece. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, Aristotle University of Thessaloniki, University of Thessaly, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute.Nanofluids refer to dilute liquid suspensions of nanoparticles in commonly used heat transfer liquids. They triggered much excitement since mid 1990s mainly owing to the claims of anomalous enhancement of thermal conductivity even at very low nanoparticle concentrations. There have been
numerous attempts to interpret the mechanism(s) that drive the displayed enhancement. A long debate within the research community supported by experimental and theoretical evidence has highlighted the nanoparticle
structuring as the dominant underlying mechanism. On the other hand the viscosity increase as a result of nanoparticle structuring raises concerns about their suitability for certain applications. This paper mainly discusses the structure – property relationship for nanofluids in microscopically static conditions
CLIL Trajectories in Colombia: Stakeholders¿ and Experts¿ Insights
No full text16 páginasThis chapter presents the results of a study carried out in schools and universities in Colombia, with a twofold purpose: (a) to identify the factors of success, sustainability and inadequacy that may have favoured and/or hindered the efficient implementation of CLIL, and (b) to determine horizons for teacher training in Colombia and the region. The study follows a mixed methods approach and makes use of semi-structured questionnaires, interviews and focus groups. The study aims to update the state of the art in the field, while shedding light on policy construction, design, implementation and quality assurance services for teacher education institutions and agents interested in improving bilingual education and CLIL. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024
