AI Alignment Dialogues: An Interactive Approach to AI Alignment in Support Agents
No full textThis project proposes a different way of looking at AI alignment, namely by introducing AI Alignment Dialogues. We argue that alignment dialogues have a number of advantages in comparison to data-driven approaches, especially for behaviour support agents, which aim to support users in achieving their desired future behaviours rather than their current behaviours. The advantages of alignment dialogues include allowing the users to directly convey higher-level concepts to the agent and making the agent more transparent and trusted. Interactive Intelligenc

The new cultural city: The future of Tainan city in Taiwan’s metropolitan development process
No full textWith the construction of high-speed railway in 2007, and the establishment of five direct controlled municipalities along the west coast of Taiwan in 2010, theses changes offer opportunities to redirect and redefine the role of Tainan and its spatial strategy. The project first discuss the possible morphology for south region. With serious analysis to tackle on the possible relationship between Tainan and Kaohsiung thus to re-identify the role of Tainan city. The analysis and the references made me to decide to use culture-led urban regeneration as the strategy to revitalize Tainan’s potentiality, solve city’s social and economic problems. At the same time to strengthen the complimentary relationship between Tainan and Kaohsiung. First, Tainan city scale strategy will be presented together with serious infrastructure planning. By achieving multimodal transport city to prepare a better condition for the following intervention. When step into the design parameter, tackle on neighborhood scale and discuss the issue of what kind of regeneration can revitalize local culture resources and attract the clustering of creative cluster.complex citiesUrbanismArchitectur
New Bridge Keepers
No full textThe project concerns a minimal spatial design that re-invents the watersystem in South-Holland by connecting waterways with roads through social use. The water system of Holland functions not only as a very imporant structure to keep our feet dry, as well as a vital transport organ and recreational layer. Because of the developments in the past century, the water system is mainly taken over by train and car infrastructures. As a result, vacancy and water systems correlate (such as: bridge control houses). The intertwinement of the Dutch water system with the geo-morphological, natural, social-economical and historical context of the Netherlands make the intersection of the water and ways (bridge) an interesting occasion to (re)root the urban layer (the Randstad) with its underlaying context. How can vacant areas be transformed into a valuable resource for this problem? In this thesis, a design solution will be presented that will clearify and reintergrate this lost connection.Landscape ArchitectureUrbanismArchitecture and The Built Environmen
Sand movement by wind
No full textSand movement on the coast by wind action can be a major factor in some areas, yet very little is known about the basic mechanisms of movement by wind. With the growing use of artificial placement of sand material for beach restoration and protection, movement of sand by wind in the area shoreward of the waterline has become more and more a matter of concern. The need for greater knowledge in this area has recently been emphasized by proposed plans for the rehabilitation of vast offshore sand island areas along the eastern seaboard. This report discusses some earlier experimental results in wind tunnels, and describes and compares results obtained from new wind tunnel tests. Work by another investigator, directly related to the author's work, has been included in an addendum. This latter work extends the investigation to smaller sand size range and suggests that different relationships for threshold shear velocity for sand movement obtain for the smaller sand size distributions. Of particular interest are tests on the influence of moisture content on sand movement. The experimental date clearly demonstrate that as the sand moisture content increases, the value of the threshold shear velocity of sand movement may also materially increase. Quantitative expression of this effect is obtained
