Spatiocolorimetric neighborhood hypergraph and Image Processing Applications : Noise Removal and Edge Detection.
2004
In this document, we are interested in image modeling by the means of the hypergraph theory. Our contribution is essentially centered on the determination of the properties resulting from this theory and on the analysis from their adequacy with image problems, particularly edge and noise detection.First, we study the image spatiocolorimetric neighborhood hypergraph representation. Three representations are respectively presented incorporating global properties, local properties and similarity functions. Then, we use the hypergraph properties generated by the representation in order to define the structural models of noise and edge. This enables us to deduce the algorithms of noise suppressi…
Angular Dependency of Hyperspectral Measurements over Wheat Characterized by a Novel UAV Based Goniometer
2015
In this study we present a hyperspectral flying goniometer system, based on a rotary-wing unmanned aerial vehicle (UAV) equipped with a spectrometer mounted on an active gimbal. We show that this approach may be used to collect multiangular hyperspectral data over vegetated environments. The pointing and positioning accuracy are assessed using structure from motion and vary from σ = 1° to 8° in pointing and σ = 0.7 to 0.8 m in positioning. We use a wheat dataset to investigate the influence of angular effects on the NDVI, TCARI and REIP vegetation indices. Angular effects caused significant variations on the indices: NDVI = 0.83–0.95; TCARI = 0.04–0.116; REIP = 729–735 nm. Our analysis high…
Genome-wide association analysis identifies six new loci associated with forced vital capacity
2014
Forced vital capacity (FVC), a spirometric measure of pulmonary function, reflects lung volume and is used to diagnose and monitor lung diseases. We performed genome-wide association study meta-analysis of FVC in 52,253 individuals from 26 studies and followed up the top associations in 32,917 additional individuals of European ancestry. We found six new regions associated at genome-wide significance (P < 5 × 10−8) with FVC in or near EFEMP1, BMP6, MIR129-2–HSD17B12, PRDM11, WWOX and KCNJ2. Two loci previously associated with spirometric measures (GSTCD and PTCH1) were related to FVC. Newly implicated regions were followed up in samples from African-American, Korean, Chinese and Hispanic in…
Redução da sobrecarga do cuidador após o treinamento supervisionado em idosos pluripatológicos e paliativos
2021
Objetivo. Conocer la relación entre el nivel de independencia de un grupo de ancianos crónicos-pluripatológicos y paliativos (ACP-P) y la sobrecarga de sus cuidadores, tras un programa de entrenamiento multicomponente adaptado al ámbito domiciliario. Diseño mixto, cuantitativo y cuasiexperimental, con medidas repetidas en el factor Entrenamiento, y dos factores de agrupación: edad (70-79 y ≥80 años) y nivel de deambulación del ACP-P (anda/no anda). Emplazamiento. Intervención realizada en la Unidad de Hospitalización a Domicilio (UHD) del Hospital General de Alicante, durante 2014-2016. Participantes. 17 pacientes ACP-P, edad media 81,6 años (DE 5,6). Intervención. 3 sesiones semanales dura…
Disfunkcionālas ģimenes ietekme uz bērnu - speciālistu un cilvēku no šādām ģimenēm viedokļi
2021
Bakalaura darbs “Disfunkcionālas ģimenes ietekme uz bērnu – speciālistu un cilvēku no šādām ģimenēm viedokļi” ir par personām, kuras ir auguši disfunkcionālā ģimenē. Darba mērķis ir noskaidrot indivīdu, kuri auguši disfunkcionālā ģimenē un speciālistu, kuri ikdienā strādā ar bērniem no disfunkcionālām ģimenēm viedokli par ietekmi, ko atstāj augšana šādā ģimenē. Darba uzdevums ir noskaidrot personu, kuri auguši disfunkcionālā ģimenē un speciālistu, kuri ikdienā strādā ar bērniem no disfunkcionālām ģimenēm viedokli par ietekmi, ko atstāj augšana šādā ģimenē, kā arī salīdzināt abu atlasītu grupu viedokļus un noskaidrot, kā personas no disfunkcionālām ģimenēm pārvar bērnībā gūto traumu. Pēc dar…

Balance confidence and functional balance are associated with physical disability after hip fracture
2012
Background. This cross-sectional study investigated the associations between balance confidence, functional balance, and physical disability among older people after hip fracture. Material and methods. The study utilizes baseline data of two randomized controlled trials (ISRCTN34271567 and ISRCTN53680197). The participants were 159 community-dwelling over 60-year-old people. Health, fracture status, the date and type of surgery, and contraindications for participation were assessed in a clinical examination. Balance confidence was assessed by the Activities-specific Balance Confidence Scale (ABC) and functional balance by the Berg Balance Scale. Physical disability was assessed by a questio…
Vulnerabilidad cognitiva a la hipocondría: intrusiones, valoraciones y creencias disfuncionales/ Cognitive vulnerability to hypochondriasis: intrusio…
2019
La hipocondría es un trastorno caracterizado por el miedo o la creencia de padecer una enfermedad grave a partir de la interpretación negativa de los signos y síntomas corporales. La confirmación por parte de un médico, después de una evaluación exhaustiva, de que el paciente no padece una enfermedad médica, no tiene como resultado una tranquilización segura y duradera. Por lo general, las personas que presentan hipocondría pueden experimentar una reducción de la ansiedad después de visitar al médico, pero esta reducción dura solo horas o días. Cuando se presenta otro síntoma, la ansiedad reaparece y el ciclo de preocupación hipocondríaca se reanuda. Además, la hipocondría se puede manifest…
On the History of Differentiable Manifolds
2012
International audience; We discuss central aspects of history of the concept of an affine dif-ferentiable manifold, as a proposal confirming the need for using some quantitative methods (drawn from elementary Model Theory) in Mathematical Historiography. In particular, we prove that this geometric structure is a syntactic rigid designator in the sense of Kripke-Putnam.
