Three-dimensional spectral measurements of paint samples using optical coherence tomography
No full textIn this study, we describe a method for measuring the spectral reflectance of a paint layer at both the surface and in the volume of the paint layers. We first present a fringes model which illustrates the possibilities for spectral reconstruction using a Short-Time-Fourier-Transform algorithm. We investigate the remaing percentage errors and identified that there is a strong fluctuation along the wavelength range of the spectrometer. Then, we demonstrate the validity of our approach experimentally by measuring the spectral reflectance of a paint layer using a custom-made visible light optical coherence tomography system. There, we reconstruct the spectral reflectance of a paint layer by probing the surface and a depth range below the surface. Finally, we show the importance to include a wavelength sensitive correction in the reconstruction for taking into account the spectral shape of the light in the reference path of the interferometer. This work is part of the Down To The Ground project, in which the results of the OCT inspection will be used directly by a consortium of technical art historians and conservators.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.Structural Integrity & Composite
Optimizing payments in dominant-strategy mechanisms for multi-parameter domains
No full textIn AI research, mechanism design is typically used to allocate tasks and resources to agents holding private information about their values for possible allocations. In this context, optimizing payments within the Groves class has recently received much attention, mostly under the assumption that agent’s private information is single-dimensional. Our work tackles this problem in multi-parameter domains. Specifically, we develop a generic technique to look for a best Groves mechanism for any given mechanism design problem. Our method is based on partitioning the spaces of agent values and payment functions into regions, on each of which we are able to define a feasible linear payment function. Under certain geometric conditions on partitions of the two spaces this function is optimal. We illustrate our method by applying it to the problem of allocating heterogeneous items

Factors underlying migratory bat aggregations in chestnut groves
No full textDeciduous woodlands have undergone major structural changes in Europe in the course of the last century. Dense woodlands have, for instance, replaced traditionally managed, open sweet chestnut groves, and have led to biodiversity losses. Surveys carried out in the southern Alps have shown that the frequency of occurrence of the rare migratory Leisler’s bat Nyctalus leisleri in bat boxes is much higher in managed than in unmanaged chestnut groves, pointing to the importance of traditional groves as stopover sites. To identify the reasons for this habitat preference we investigated whether managed chestnut groves constitute a more appropriate foraging ground than closed stands, and whether bat boxes in managed chestnut groves offer more suitable temperature conditions for roosting. Foraging habitat selection and roost usage were investigated by means of radiotracking and temperature loggers, respectively. Foraging Leisler’s bats predominantly selected deciduous woodlands over other habitat types, but showed no distinct preference for either type of chestnut grove over other forest types. In managed chestnut groves, bats used cooler boxes than others available in the same habitat, but there was no difference in temperature between the boxes used in managed versus unmanaged groves. Our results provide no evidence that foraging opportunities or roost temperature dictate the forest-specific pattern of bat box occupancy. As an alternative explanation, we suggest that managed chestnut groves may represent optimal lekking arenas due to their open structure and high roost density. Whatever the reason for this habitat preference, partially maintaining traditional management, resulting in a semi-open, mosaic landscape, is likely key to maintaining chestnut groves attractive for this migratory bat

Undominated Groves mechanisms
No full textThe family of Groves mechanisms, which includes the well-known VCG mechanism (also known as the Clarke mechanism), is a family of efficient and strategy-proof mechanisms. Unfortunately, the Groves mechanisms are generally not budget balanced. That is, under such mechanisms, payments may flow into or out of the system of the agents, resulting in deficits or reduced utilities for the agents. We consider the following problem: within the family of Groves mechanisms, we want to identify mechanisms that give the agents the highest utilities, under the constraint that these mechanisms must never incur deficits. We adopt a prior-free approach. We introduce two general measures for comparing mechanisms in prior-free settings. We say that a non-deficit Groves mechanism M individually dominates another non-deficit Groves mechanism M' if for every type profile, every agent's utility under M is no less than that under M', and this holds with strict inequality for at least one type profile and one agent. We say that a non-deficit Groves mechanism M collectively dominates another non-deficit Groves mechanism M' if for every type profile, the agents' total utility under M is no less than that under M', and this holds with strict inequality for at least one type profile. The above definitions induce two partial orders on non-deficit Groves mechanisms. We study the maximal elements corresponding to these two partial orders, which we call the individually undominated mechanisms and the collectively undominated mechanisms, respectively.Mingyu Guo, Evangelos Markakis, Krzysztof R.
