    Computational pattern making from 3D garment models

    Full text link
    We propose a method for computing a sewing pattern of a given 3D garment model. Our algorithm segments an input 3D garment shape into patches and computes their 2D parameterization, resulting in pattern pieces that can be cut out of fabric and sewn together to manufacture the garment. Unlike the general state-of-the-art approaches for surface cutting and flattening, our method explicitly targets garment fabrication. It accounts for the unique properties and constraints of tailoring, such as seam symmetry, the usage of darts, fabric grain alignment, and a flattening distortion measure that models woven fabric deformation, respecting its anisotropic behavior. We bootstrap a recent patch layout approach developed for quadrilateral remeshing and adapt it to the purpose of computational pattern making, ensuring that the deformation of each pattern piece stays within prescribed bounds of cloth stress. While our algorithm can automatically produce the sewing patterns, it is fast enough to admit user input to creatively iterate on the pattern design. Our method can take several target poses of the 3D garment into account and integrate them into the sewing pattern design. We demonstrate results on both skintight and loose garments, showcasing the versatile application possibilities of our approach.</jats:p

    Reggio Emilia hospital installed Picture Archiving and Communications Systems (PACS) as the final step towards a completely digital clinical environment completing the HIS/EMR and 1,400 web/terminals for patient information access. Financial benefits throughout the hospital were assessed upfront and measured periodically. Key indicators (radiology exam turnaround time, number of radiology procedures performed, inpatients length of stay before and after the PACS implementation, etc.) were analyzed and values were statistically tested to assess workflow and productivity improvements. The hospital went “filmless” in 28 weeks. Between the half of 2004 and the respective period in 2003, overall Radiology Department productivity increased by 12%, TAT improved by more than 60%. Timelier patient care resulted in decreased lengths of stay. Neurology alone experienced a 12% improvement in average patient stay. To quantify the impact of PACS on the average hospital stays and the expected productivity benefits to inpatient productivity were used a “high level” and a “detailed” business model. Annual financial upsides have exceeded $1.9 millions/year. A well-planned PACS deployment simplifies imaging workflow and improves patient care throughout the hospital while delivering substantial financial benefits. Staff buy-in was the key in this process and on-going training and process monitoring are a must

    Integrative neurobiology of metabolic diseases, neuroinflammation, and neurodegeneration

    Alzheimer’s disease (AD) is a complex, multifactorial disease with a number of leading mechanisms, including neuroinflammation, processing of amyloid precursor protein (APP) to amyloid β peptide, tau protein hyperphosphorylation, relocalization and deposition. These mechanisms are propagated by obesity, the metabolic syndrome and type-2 diabetes mellitus. Stress, sedentariness, dietary overconsumption of saturated fat and refined sugars, and circadian derangements/disturbed sleep contribute to obesity and related metabolic diseases, but also accelerate age-related damage and senescence that all feed the risk of developing AD too. The complex and interacting mechanisms are not yet completely understood and will require further analysis. Instead of investigating AD as a mono- or oligocausal disease we should address the disease by understanding the multiple underlying mechanisms and how these interact. Future research therefore might concentrate on integrating these by systems biology approaches, but also to regard them from an evolutionary medicine point of view. The current review addresses several of these interacting mechanisms in animal models and compares them with clinical data giving an overview about our current knowledge and puts them into an integrated framework

    Musical settings of Apollinaire's "Bestiaire ou Cortège d'Orphée (1911) by Francis Poulenc, Louis Durey and anothers composers : Analysis and stylistic study

    Le Bestiaire ou Cortège d’Orphée (1911) d’Apollinaire attire toujours les mélodistes de notre temps. S’inscrivant dans une tradition ancestrale, les mises en musique des petits poèmes d’animaux guidés par Orphée constituent en effet un inestimable « jardin zoologique » pour les musiciens. Apollinaire imaginait-il une exploration de ce type ? Ces créations musicales à partir du Bestiaire sont-elles, à titre posthume, un hommage au poète ? Des plus célèbres, celles de Poulenc et Durey (1919), à celle de Régis Campo (2008) en passant par les recueils de Claude Ballif et Robert Caby (1945), chacune des versions donne lieu à un réinvestissement spécifique des poèmes. Dans cette étude diachronique allant de 1919 à 2008, les compositions concernées sont analysées dans leur contexte puis examinées à travers la pluralité des langages musicaux qu’elles mettent en oeuvre. Outre Poulenc et Durey, voici, par ordre chronologique, les auteurs abordés : Yves Nat (Dans vos viviers, dans vos étangs, 1943) ; Claude Ballif (Le Cortège d’Orphée, op. 1b, 1945-1948) ; Robert Caby (Cycle inédit de sept mélodies, 1945-1948) ; Robert Cornman (Le Bestiaire Alpha, 1961-1963, Le Bestiaire Bêta, 1972) ; Jean Absil (Bestiaire op. 58, 1964) ; Lionel Daunais (Bestiaire, 1978) ; plus près de nous : May Breguet (Bestiaire, 1982) ; Alain Corbellari (Bestiaire bis, 1991) ; Rachel Laurin (Bestiaire op. 22, 1992) ; enfin, John Carbon (Bestiaire, 2002) et Régis Campo (Bestiaire, 2008)The poem collection Le Bestiaire or Cortège d’Orphée (1911) by Apollinaire still attracts vocal composers of our time. Drawing on ancestral traditions, the setting to music of short poems about animals guided by Orpheus constitutes an inestimable “zoo” for musicians. Did Apollinaire imagine an exploration of this type? Are these musical creations, from Le Bestiaire onward, posthumously, homages to Apollinaire? From the most famous of animal cycles by Poulenc and Durey (1919), to that of Régis Campo (2008), as well as the collections of Claude Ballif and Robert Caby (1945) , each version gives rise to a specific reingagement with the poems. In this diachronic study from 1919 to 2008, the compositions in question are analyzed in their context and examined through the plurality of musical languages that they employ. In addition to Poulenc and Durey, here, in chronological order, are the other composers discussed: Yves Nat (Dans vos viviers, dans vos étangs, 1943); Claude Ballif (Le Cortège d’Orphée, op. 1b, 1945-1948); Robert Caby (Cycle of seven songs, 1945-1948); Robert Cornman (Le Bestiaire Alpha, 1961-1963, Le Bestiaire Bêta, 1972); Jean Absil (Bestiaire, op. 58, 1964); Lionel Daunais (Le Bestiaire, 1978); more recent, May Breguet (Bestiaire, 1982); Alain Corbellari (Bestiaire bis, 1991); Rachel Laurin (Bestiaire, op. 22, 1992); and, finally, John Carbon (Bestiaire, 2002) and Régis Campo (Le Bestiaire, 2008

    Bir dîn felsefesi mümkün müdür?

    No full text
    Din felsefesi ve bilim felsefesi deyimleri, ilki Hegel, ikincisi Comte ve o Ampere tarafından aşağı yukarı aynı tarihlerde ortaya atıldı. Fakat her ikisi de aynı derecede yaygınlaşmadı. Bilim felsefesi deyimi, haklı olarak daha çabuk kabûl gördü. Çünkü onun taşıdığı anlam daha belirgindir. Ufuk ve vokabüler belirsizliklerine rağmen bilim felsefesi, filozoflar arasında yaşama hakkını elde etti ve günümüzde, bazı mantık kitaplarının, büyük bölümünü işgal edeek derecede önem kazandı. Din felsefesi deyimi, bir ölçüde başarılı olduktan sonra şansızlığa uğradı. Bugün ona, ancak sınırlı bir kredi tanınmaktadır. Bu deyim, müphemlik arzetmekte ve üzerine tereddüdün gölgesi düşmektedir. Hegel’in ona verdiği anlam tümüyle beğenilmedi. Çünkü bu anlam, bir sistemin ayrılmaz parçasıydı. Din fel­ sefesinin, ruhun gelişmesinde oynadığı rol ve kazandığı ifadeye göre dinî feno­ men üzerine bir düşünmeyi belirtebilmesi için, bu gelişmenin kanununu tanıya­ bileceğimiz hayaline kapılmak ve Hegel olmak gerekecektir. Hegel bir din felsefesinden çok bir din "tarihi felsefesi" yaptı. Fakat formüllerin yer değiştirmesi konuyu daha çok aydınlatmaz; güçlüğü çözemez, arttırır

    Les cylindres de forme prismatique peuvent être représentés par un assemblage de bandes rectilignes. A partir de la connaissance de la matrice de transition d'une bande élémentaire, la théorie de la diffusion multiple permet le calcul de la diffraction par un cylindre prismatique. On traite d'abord le cas d'un cylindre dont la frontière est fermée (cylindre à section carrée) et l'on compare les résultats à une résolution directe par équation intégrale de Helmholtz. On présente ensuite des résultats théoriques et expérimentaux sur des réflecteurs paraboliques formés de tubes compliants.Prismatic cylinders can be represented by an assembly of strips. The transition matrix of an individual strip being known, the scattering from a prismatic cylinder can be computed using the multiple scattering theory. Cases where the boundary of the cylinder is closed (square cylinder) are first presented and the results are compared to a direct solution using the Helmholtz integral equation. Then, theoretical and experimental results on parabolic reflectors formed with compliant tubes are given
