Computer Vision Cubed: A Framework for Rubik's Cube Turn Classification
No full textThe niche world of competitive Rubik's Cube solving is growing. This project seeks to develop an automatic coaching platform for speedcubers' development and efficiency.
This task of presenting automatic, targeted feedback to users is broken down into two sub-problems. Leveraging machine learning techniques, this thesis presents solutions to both sub-problems.
Due to time constraints, only part of the outlined solutions are successfully implemented in the scope of this thesis. Further work is discussed and proposed
“Le masculin l’emporte sur le feminin” - Pourquoi est-ce qu’il importe: Using Word Embeddings to Quantify the Effect of French “L’Écriture Inclusive”
No full textThe French language is characterized by grammatical domination of the masculine gender over the feminine gender. It is widely posited that this grammatical gender inequality manifests itself as social gender inequality in French society. As a result, many feminist thinkers advocate for the widespread use of “écriture inclusive,” a collection of grammatical practices that seek to improve the visibility of women in the written language. Word embedding language models capture social and cultural biases in their mathematical encodings of words as vectors. These embeddings can be used to quantify social ideologies and social change. The goal of this work is to quantify the effects of “écriture inclusive” at improving gender equality. This is done through the construction of a French corpus dataset in which these writing practices appear frequently. This dataset is then used to train a word embeddings language model. The values of these word embeddings are then evaluated on the basis of their mathematical alignment with either the masculine or feminine gender. The results quantify the effects that “écriture inclusive” has on the status of women in French society and show that less masculine values are encoded in word vectors when using inclusive language word forms
Indigenous Peoples and Litigation:Strategies for Legal Empowerment
No full textAcross the globe indigenous peoples are increasingly using litigation to seek remedies for violation of their fundamental human rights. The rise of litigation is to be placed in the larger issue of increased land grabbing, natural resources exploitation and the general lack of recognition of their rights at the national level. This lack of legal rights is usually coupled with a lack of political will to address the issues faced by indigenous peoples, often leading to serious human rights violations, leaving indigenous advocates with few options but to turn to courts as a last resort to seek remedies. This article examines some of the issues faced by indigenous peoples and their advocates when engaging in human rights litigation. The goal is to offer a practice-based reflection on the encounter between courts and indigenous peoples with a specific focus on analysing strategies to ensure their legal empowerment. This is particularly important knowing the technicality, externalities and complexities of the process of litigation, and the fact that many decisions do not get implemented. In this context this article explores how the process of litigation in itself can support legal empowerment and the wider fight for justice. © 2020, The Author(s).

A parametric study of vestibular stimulation during centrifugation
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2006.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections."February 2006."Includes bibliographical references (p. 155-160).Artificial Gravity (AG) provided by short-radius centrifugation is a promising countermeasure to the health problems associated with long duration human spaceflight. Head-turns performed during centrifugation, however, trigger a disturbing vestibular response that is only qualitatively understood. In order to design an efficient incremental adaptation procedure, the present study investigates the quantitative aspect of the vestibular side effects associated with AG, in particular, the relationship among crosscoupled stimulation, vestibular response, and adaptation. We tested 20 young adults with supine right-quadrant yaw head-turns performed in a dark environment during short-radius centrifugation. We studied the changes in vestibular response and adaptation to head-turns at different levels of cross-coupled stimulation. Nine combinations of head-turn angle (20°, 40° or 80°) with centrifugevelocity (12, 19 or 30 rpm) were tested over two consecutive days.(cont.) There were four key findings: 1. All measures, except the slow-phase velocity (SPV) peak amplitude of the vestibulo-ocular reflex, decrease significantly between the two experimental days, which demonstrates that significant adaptation is achieved. 2. Large head-angles lead to longer vertical vestibulo-ocular reflex time-constants than smaller angles do, but do not lead to greater adaptation. 3. In the nose-up position, the perceived body-tilt is highly correlated with the true tilt of the gravito-inertial force at mid-chest level. 4. The SPV-peak amplitude and all subjective ratings except body-tilt show significant correlation with the intensity of the cross-coupled stimulus (CCS): the larger the CCS, the stronger the vestibular response.by Jeremie M.

Exploring the value of smart offices
No full textThis research explores the value that smart offices can provide to real estate investors. Through an extensive literature review a theoretical framework is created on the topics of smart technology, added value, the real estate investor and the real estate user. Then, three case studies are studied in depth by interviewing involved stakeholders. For each case an overview is created of what makes the building a smart building. Furthermore a connection is made between the smart technology and the way it contributes to the added values found through the literature review. In the end a Smart Value Map is created that connects smart technology, with added value and the main objectives of the investor. This way, by following the smart value map, smart technology is shown to provide value in various ways. It can improve the satisfaction of the users, it can increase the indoor environment, branding, culture. Furthermore, smart technology can be used to increase operational efficiency to reduce costs, increase adaptability and sustainability.Architecture, Urbanism and Building Science
The cross-tissue metabolic response of abalone (Haliotis midae) to functional hypoxia
No full textFunctional hypoxia is a stress condition caused by the abalone itself as a result of increased muscle activity, which generally necessitates the employment of anaerobic metabolism if the activity is sustained for prolonged periods. With that being said, abalone are highly reliant on anaerobic metabolism to provide partial compensation for energy production during oxygen-deprived episodes. However, current knowledge on the holistic metabolic response for energy metabolism during functional hypoxia, and the contribution of different metabolic pathways and various abalone tissues towards the overall accumulation of anaerobic end-products in abalone are scarce. Metabolomics analysis of adductor muscle, foot muscle, left gill, right gill, haemolymph and epipodial tissue samples indicated that South African abalone (Haliotis midae) subjected to functional hypoxia utilises predominantly anaerobic metabolism, and depends on all of the main metabolite classes (proteins, carbohydrates and lipids) for energy supply. Functional hypoxia caused increased levels of anaerobic end-products: lactate, alanopine, tauropine, succinate and alanine. Also, elevation in arginine levels was detected, confirming that abalone use phosphoarginine to generate energy during functional hypoxia. Different tissues showed varied metabolic responses to hypoxia, with functional hypoxia showing excessive changes in the adductor muscle and gills. From this metabolomics investigation, it becomes evident that abalone are metabolically able to produce sufficient amounts of energy when functional hypoxia is experienced. Also, tissue interplay enables the adjustment of H. midae energy requirements as their metabolism shifts from aerobic to anaerobic respiration during functional hypoxia.

Sharp Strichartz estimates for the wave equation on a rough background
No full textAbstract. In this paper, we obtain sharp Strichartz estimates for solutions of the wave equation gφ = 0 where g is a rough Lorentzian metric on a 4 dimensional space-time M. This is the last step of the proof of the bounded L2 curvature conjecture proposed in [3], and solved by S. Klainerman, I. Rodnianski and the author in [8], which also relie
Some computations about Kazhdan-Lusztig cells in affine Weyl groups of rank 2
No full textIn the last section of the paper "Generalized induction of Kazhdan-Lusztig cells" and in "Kazhdan-Lusztig cells in affine Weyl groups of rank 2" the author described the partition into Kazhdan-Lusztig cells of the affine Weyl groups of rank 2 for all choices of parameters. The proof of these results relies on some explicit computations with GAP. In these notes we give some details of these computations
