Urban underground space: Solving the problems of today’s cities
No full textAbstractThe world-wide trend of increased urbanisation creates problems for expanding and newly-developing cities alike. Population increase leads to an increased demand for reliable infrastructure, nowadays combined with a need for increased energy efficiency and a higher environmental awareness of the public. The use of underground space can help cities meet these increased demands while remaining compact, or find the space needed to include new functions in an existing city landscape. In many cases, underground solutions to urban problems are only considered if all other (above ground) options have been exhausted. When underground solutions are considered and evaluated from the planning or initial project stages onwards, more optimal solutions will become possible.Use of the underground is not limited to large scale infrastructure projects. This paper also shows innovative use of the underground for commercial and residential use, storage, water conveyance and treatment, and heritage conservation, and highlights how use of underground can bring more optimal solutions for urban development
Simulated Annealing-based Ontology Matching
No full textOntology alignment is a fundamental task to reconcile the heterogeneity among various information systems using distinct information sources. The evolutionary algorithms (EAs) have been already considered as the primary strategy to develop an ontology alignment system. However, such systems have two significant drawbacks: they either need a ground truth that is often unavailable, or they utilize the population-based EAs in a way that they require massive computation and memory. This article presents a new ontology alignment system, called SANOM, which uses the well-known simulated annealing as the principal technique to find the mappings between two given ontologies while no ground truth is available. In contrast to population-based EAs, the simulated annealing need not generate populations, which makes it significantly swift and memory-efficient for the ontology alignment problem. This article models the ontology alignment problem as optimizing the fitness of a state whose optimum is obtained by using the simulated annealing. A complex fitness function is developed that takes advantage of various similarity metrics including string, linguistic, and structural similarities. A randomized warm initialization is specially tailored for the simulated annealing to expedite its convergence. The experiments illustrate that SANOM is competitive with the state-of-the-art and is significantly superior to other EA-based systems.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
Experimental observation and constitutive modelling of the shear strength of a natural unsaturated soil
No full textIncreasing frequency and intensity of extreme weather events in the Netherlands is raising attention on the unsaturated response of geo-infrastructures, promoting research projects to provide an overview of the impact of unsaturated conditions on the response of shallow soil layers and embankments, and to better address maintenance and mitigation measures. As part of this effort, we discuss the results of standard laboratory tests performed on initially unsaturated samples retrieved from the field and tested in natural conditions, as well as after controlled drying and wetting. The variation of the “undrained” (i.e. at constant water content) shear strength with the degree of saturation obtained from the laboratory tests aligns well with CPT measurements performed in the field. An elastic-plastic constitutive model with mixed isotropic-rotational hardening developed for saturated soft soils was extended to unsaturated conditions by following a robust approach previously developed for compacted clayey soils. Coupling between the mechanical and the hydraulic behaviour is provided by the water retention curve. The model nicely captures the response observed in the laboratory, until extreme dry conditions, which possibly alter the structure of the soil, the peak stress, and the brittleness after failure. The model is capable of reproducing the effects of the previous hydraulic history on the stress-strain behaviour observed from the laboratory tests over a wide range of degree of saturation
A Test Suite for Quantum Network Applications: Evaluation of the Distributed CNOT Application in its Ability to Benchmark Quantum Networks
No full textBenchmarks for quantum network systems currently are an underrepresented subject in the research field. This paper evaluates how informative a distributed CNOT gate application is, in recognizing errors in the total quantum system. The goal is to decide whether it should be included as a benchmark in a newly developed benchmark suite for quantum network systems. The application is simulated and its error rate on certain inputs is plotted against properties of the quantum network system. This way it is evaluated that the application is sensitive to certain parameters of the quantum link and quantum devices in the nodes. Additionally, a quantitative analysis on the results shows which inputs are most effective in reacting to errors in the total quantum system. That way it is possible to conclude that inputs in the x-basis are sensitive to the most parameters and that combining these results with the inputs |10⟩ or |11⟩ yields an optimal result. It can be included in a benchmark suite if it is sensitive to parameters to which non of the other applications in the suite are sensitive.CSE3000 Research ProjectComputer Science and Engineerin

Test Cell Design for the Development of a Hydrogen Internal Combustion Engine: Risk Mitigation of Hydrogen Leakages in a 20-feet Container
No full textA collaborative group comprising of the TU Delft, Deltion College and Dutch Electric Aviation Centre aim to develop a flying test bed for sustainable aviation. The collaborative group has acquired a Cessna 337F Skymaster with the intent to replace one of the engines with a retrofit hydrogen internal combustion engine. An ancillary engine will serve as test unit prior to modifying one of the engines of the Cessna 337F Skymaster. Experiments will be performed in a 20-feet container. Hydrogen may leak from a fuel pipe or through a fuel injector from the engine, consequently hydrogen may accumulate in the enclosed testing environment and a detonation occurs. CFD models of the test cell are simulated in ANSYS fluent. One may conclude that heat and hydrogen can be disposed of well, providing an optimal placement of the ventilation system and test cell elements.Aerospace Engineerin

No full textThe growing population in urban areas around the world puts tremendous stress on natural resources. In India, the urban population has increased form 18 percent to 34 percent of the total population between 1960 and 2017 and is expected to exceed the rural population at the end of 2040. The growing urban population will putt stress on the availability of natural resources. The access to water, a vital resource for human existence, is already one of the resources threatened by urban growth. Only 70 percent of people living in urban areas in India have access to safe drinking water through piped infrastructure. The urban poor regularly lack access to the official means of water distribution because they live in illegal houses. In Mumbai, the largest city in India, around 42 percent of people live in slums and depend on informal water distribution systems like water trucks, neighbor water taps, public water stands, private water shops, ground water pumps or water kiosks. If the growing population of Nala Sopara is housed in the same way as before, the consequences will be severe. An increase in flooding will mean that more people will be cut off from electricity, drinking water, work, education and healthcare. Therefore better access to drinking water and good protection from flooding are main goals for the expansion of Nala Sopara. This will not only result in better health of inhabitant and more time to spent on work, study and other activities but may also become a tool for community making. But how can the growing population on Nala Sopara be housed in a way that water does no longer cause a threat but becomes a resources for community growth and empowerment of the urban poor? This research will try to answer this question. The goal of the project is to come up with a housing design for the expanding areas of Nala Sopara that delivers a better solution against the problems related with water while also providing a comfortable living space for the inhabitants. Since these problems are not at all unique to Nala Sopara alone, the design may also provide solutions to similar regions in India and the Global South.Global Housing Mixing Mumbai:Architecture, Urbanism and Building Science
