Augmented and Virtual Reality techniques for footwear

The use of 3D imaging techniques has been early adopted in the footwear industry. In particular, 3D imaging could be used to aid commerce and improve the quality and sales of shoes. Footwear customization is an added value aimed not only to improve product quality, but also consumer comfort. Moreover, customisation implies a new business model that avoids the competition of mass production coming from new manufacturers settled mainly in Asian countries. However, footwear customisation implies a significant effort at different levels. In manufacturing, rapid and virtual prototyping is required; indeed the prototype is intended to become the final product. The whole design procedure must be validated using exclusively virtual techniques to ensure the feasibility of this process, since physical prototypes should be avoided. With regard to commerce, it would be desirable for the consumer to choose any model of shoes from a large 3D database and be able to try them on looking at a magic mirror. This would probably reduce costs and increase sales, since shops would not require storing every shoe model and the process of trying several models on would be easier and faster for the consumer. In this paper, new advances in 3D techniques coming from experience in cinema, TV and games are successfully applied to footwear. Firstly, the characteristics of a high-quality stereoscopic vision system for footwear are presented. Secondly, a system for the interaction with virtual footwear models based on 3D gloves is detailed. Finally, an augmented reality system (magic mirror) is presented, which is implemented with low-cost computational elements that allow a hypothetical customer to check in real time the goodness of a given virtual footwear model from an aesthetical point of view.

La aplicación de stop-motion en arquitectura: materia y luz

Se inicia un análisis de los procesos de trabajo de stop-motion porque ayudan a comprender las diferentes escalas en arquitectura donde las maquetas se convierten en futuros prototipos de infraestructuras de edificios o de paisaje. Stop motion es una técnica de animación fotograma a fotograma de objetos estáticos mediante la manipulación de figuras de plastilina en entornos fijos con cambios de luz, color y sonido. Igual que dicha técnica reúne lo mejor del rodaje tradicional -story board, escenografía, fotografía, personajes, iluminación- la animación de maquetas de interiores sintetiza micro-procesos de mayor repercusión -habitaciones con cambios de humedad, de temperatura, de ventilación y de iluminación- incorporando efectos especiales que son procesados digitalmente en post-producción. Se construyen varios prototipos de habitación con parámetros fijos como el tamaño y la posición de la cámara y otros variables como los materiales, los personajes y la iluminación. Representan un mundo en miniatura que intenta aportar un acercamiento sensorial y atmosférico analizando la magia y la fantasía que Junichirô Tanizaki describe en la penumbra de las construcciones tradicionales japonesas y estudiando las imperfecciones de los escenarios que Tim Burton manipula en su películas de animación con una textura que las tecnologías digitales no pueden igualar. El objetivo es utilizar una escala micro para realizar unos modelos interiores donde las condiciones atmosféricas están controladas y reducidas, y tomar datos que se podrían aplicar a un proceso de modelado a escala intermedia para testar prototipos de edificios como el túnel de viento; o, finalmente, a una escala macro con maquetas de un sector de la costa o de un río donde los fenómenos meteorológicos son los protagonistas para simular inundaciones y diseñar futuras medidas de prevención y seguridad.

College Book 7, 1750-1778

This volume contains a fair copy of minutes from Corporation meetings held from Sept. 17, 1750 through April 23, 1778. It begins with an alphabetical index and contains entries related to a wide range of topics, including the challenges of operating the Charlestown ferry (due to the river freezing, fear of smallpox, and other issues); increases in "pecuniary mulcts" (fines) for breaches of specific College laws; the establishment of the Dudleian lecture; the selection and financial support of missionaries to various Indian tribes; honorary degrees awarded to Benjamin Franklin and George Washington; gifts to the library as it was rebuilt in the wake of the fire of 1764 (many entries provide the title and author of books donated); the management of land and property belonging to Harvard; Treasurers' reports and other financial accounts; changes in the College laws; gifts to the College, ranging from two Egyptian mummies to a solar microscope; the construction of the First Parish Meeting House in Cambridge and the use of adjacent College property by parishoners; rules of endowed professorships; salaries and appointments; closures due to the threat of smallpox; rules governing Commons and the College Library; reports of various Visiting Committees; class schedules, according to subject; student disorders; the establishment of a designated museum space to display "Curiosities"; the effects of the Revolutionary War on Harvard, including repeated requests to the General Court after the war for compensation for damage to College buildings; the cost of various foods and changes in what was served at Commons; and the danger of the chapel's roof, built of too-heavy slate, falling in. Also of interest are minutes from a May 5, 1761 meeting, which note that the General Court voted to pay for Hollis Professor John Winthrop to travel to Newfoundland to observe the transit of Venus "over the Suns disc."

Student mathematical notebook of William Tudor, 1795

Notebook containing the handwritten mathematical exercises of William Tudor, kept in 1795 while he was an undergraduate at Harvard College. The volume contains rules, definitions, problems, drawings, and tables on geometry, trigonometry, surveying, calculating distances, sailing, and dialing. Some of the exercises are illustrated with hand-drawn diagrams. The Menusration of Heights and Distances section contains color drawings of buildings and trees, and some have been altered with notes in different hands and with humorous additions. For instance, a drawing of a tower was drawn into a figure titled “Egyptian Mummy.” Some of the images are identified: “A rude sketch of the Middlesex canal,” Genl Warren’s monument on Bunker Hill,” “Noddles Island,” “the fields of Elysium,” and the “Roxbury Canal.” The annotations and additional drawings are unattributed.

Potential Shifts in Canadian High Arctic Sedimentary Organic Matter Composition With Permafrost Active Layer Detachments

Increased temperature and precipitation in Arctic regions have led to deeper thawing and structural instability in permafrost soil. The resulting localized disturbances, referred to as active layer detachments (ALDs), may transport organic matter (OM) to more biogeochemically active zones. To examine this further, solid state cross polarization magic angle spinning 13C nuclear magnetic resonance (CPMAS NMR) and biomarker analysis were used to evaluate potential shifts in riverine sediment OM composition due to nearby ALDs within the Cape Bounty Arctic Watershed Observatory, Nunavut, Canada. In sedimentary OM near ALDs, NMR analysis revealed signals indicative of unaltered plant-derived material, likely derived from permafrost. Long chain acyclic aliphatic lipids, steroids, cutin, suberin and lignin occurred in the sediments, consistent with a dominance of plant-derived compounds, some of which may have originated from permafrost-derived OM released by ALDs. OM degradation proxies for sediments near ALDs revealed less alteration in acyclic aliphatic lipids, while constituents such as steroids, cutin, suberin and lignin were found at a relatively advanced stage of degradation. Phospholipid fatty acid analysis indicated that microbial activity was higher near ALDs than downstream but microbial substrate limitation was prevalent within disturbed regions. Our study suggests that, as these systems recover from disturbance, ALDs likely provide permafrost-derived OM to sedimentary environments. This source of OM, which is enriched in labile OM, may alter biogeochemical patterns and enhance microbial respiration within these ecosystems.

DEMOCRACY AND CITIZENSHIP IN NORTH AFRICA AFTER THE ARAB AWAKENING: CHALLENGES FOR EU AND US FOREIGN POLICY (EUSPRING). Arab Citizenship Review No. 6, October 2014. EGYPT. The Return to Authoritarianism and the Crisis of Citizenship Rights

Citizenship and democratic rights have been shrinking in Egypt with the rise of president Abd El Fattah El Sisi, widely popular among Egyptians who fear more violence and unrest in an increasingly volatile region. In this EU Spring Policy Brief, Moataz El Fegiery examines the political landscape in the run-up of parliamentary elections, arguing that the short term is likely to see further curtailment of acquired rights, further crackdown on the opposition and consolidation of military power. In the longer term, however, it is in the interest of Egyptian society and institutions as well as of Europe to reverse the politics of exclusion and ensure that freedoms, pluralism and participation prevent the rise of extremism and political violence.

The roots of economic challenges facing Egypt in the aftermath of the 25th January revolution. Jean Monnet Occasional Paper No. 9/2014

Introduction. Since the 25th of January 2011 revolution the Egyptian economy has been suffering on all fronts. Almost all the economic indicators have been pointing towards a deteriorating situation, and in many cases have reached the trough. Yet, the economy is still surviving. This is mainly due to the unprecedented support of some of Arab Gulf countries, whose unconditional aid has helped to mitigate the deteriorating economic conditions. The economic challenges facing Egypt have been exacerbated after the 20th of January revolution mainly because of the deteriorating political and security conditions which have interrupted the functioning of the economy. Yet, this is not to say that revolution has caused these challenges. In fact, the challenges that the Egyptian has been facing have deep roots in its socio-political-economic context, which this paper aims to explain. The revolution and its aftermath have brought to the forefront challenges which have always been mitigated by short-term solutions that never dealt seriously with their roots. Moreover, the revolution has brought additional problems associated with the macroeconomic imbalances. As a result, the challenges became more complex especially in light of the need to balance the social and economic aspects. The paper proceeds as follows; in section one we pinpoint the main challenges faced by Egypt where we identify the symptoms and causes of such challenges. In section two we discuss the roots of such challenges. Finally, we conclude and provide our understanding of how Egypt is expected to face its challenges in the near future.

Egypt: Changes and Challenges of Political Transition. MEDPRO Technical Report No. 4/May 2011

Hosni Mubarak’s regime and its power system enjoyed remarkable stability for over 30 years. On 11 February 2011, after 18 days of mass protests, the Egyptian president was forced to step down, revealing the unsustainability of the political and economic system that had ensured his continuity for so long. While the revolution of January 25th led to a major success – the fall of Hosni Mubarak – Egypt’s political future is still opaque and exposed to a number of risks. This paper first highlights the factors underpinning the former stability of Mubarak’s regime; it then assesses the causes of its underlying unsustainability, leading to the anti-government popular mobilisation in January-February 2011 and the removal of Mubarak; finally the paper evaluates the prospects for a genuine democratic transition in Egypt, by looking at the main political and socio-economic challenges facing the country.

Flashlight Europe N°2–February 2015. “Europe must now get involved in a very big way”

More than three years after al-Gaddafi was overthrown, Libya has still not returned to some semblance of normality. In many places, the Libyan state exists only on paper. No less than two governments and dozens of rival tribes, all with their own militias and armed to the teeth, are trying to come to power. In the midst of this chaos “IS,” the terrorist organization, has now entered the fray. Evidence of this is provided by the brutal murder of 21 Egyptian Copts, which could trigger off a civil war that will pose a threat to the entire region and to Europe. Mirco Keilberth, an expert on Libya, explains what is going on.
