Caractérisation des propriétés radiatives des nanoparticules de suie en présence de composés organiques / Characterization of the radiative properties of soot nanoparticles in the presence of organic compoundsLefevre, Guillaume 16 October 2018 (has links)
Les particules de suie, issues de la combustion incomplète, peuvent, en fonction des conditions de combustion, contenir une part plus ou moins importante de composés organiques (OC/TC). Par ailleurs, dès lors que ces nanoparticules sont émises dans l'atmosphère, des composés organiques volatiles peuvent s'adsorber, formant une gangue autour de ces agrégats fractals. L'impact de cette composition initiale ou de ce « vieillissement atmosphérique » sur les propriétés morphologiques et radiatives de ces particules n'est pas bien connu. Ceci a un impact sur les modèles radiatifs climatiques mais aussi sur l'interprétation des signaux délivrés par les différents diagnostics optiques pouvant être utilisés pour la métrologie des aérosols. En particulier, ce travail vise à juger de la pertinence de l'usage de diagnostics optiques pour caractériser les particules de suie en conditions atmosphériques. Afin d'étudier l'impact des composés organiques initialement présents dans la particule ou adsorbés en post-combustion sur leurs propriétés radiatives, nous avons étudié en laboratoire des suies produites par une flamme de diffusion (miniCAST) pour différentes richesses globales et avons ajouté un revêtement organique d'acide. Dans le but de générer en laboratoire une couche d'acide oléique sur des particules de référence, un dispositif de « coating » a été mis en œuvre et qualifié. Les particules ainsi générées et recouvertes ou non, ont été caractérisées en masse (mesures TEOM), en taille (mesures SMPS) et morphologiquement (densité effective). L'épaisseur de coating ainsi que la restructuration morphologique causée par l'ajout d'une gangue de matière organique ont ainsi été quantifiées. Les propriétés radiatives, ont été mesurées par extinction spectrale (Turbidimétrie) et diffusion (diffusion angulaire et spectrale). Un effort particulier a été mené pour que des mesures expérimentales puissent valider des résultats de calculs numériques préexistants. Par ailleurs, ces différentes techniques de mesures (optiques et non optique) ont conduit à la généralisation de la théorie Rayleigh Debye Gans for Fractal Aggregates (RDG-FA) à des particules de type agrégats fractals polydispersés recouverts d'un revêtement organique (RDG-CFA). Ceci permettant d'appréhender de façon phénoménologique l'impact du coating sur les propriétés radiatives et d'entrevoir une implantation plus aisée dans les codes de simulation climatique ou pour l'interprétation des mesures optiques dans l'atmosphère. Enfin, une attention particulière a été portée sur la technique d'incandescence induite par laser (LII) afin d'étudier la faisabilité de l'application de cette technique aux particules organiques ou ayant interagi avec les composés atmosphériques au cours de leur vieillissement. / Soot particles resulting from incomplete combustion may contain a more or less important part of organic compounds (OC / TC), depending on the combustion conditions. Moreover, once these nanoparticles are emitted into the atmosphere, volatile organic compounds can adsorb, forming a coating around these fractal aggregates. The impact of the initial composition or the atmospheric aging on the morphological and radiative properties of these particles is not well known. This has an impact on the radiative climate models but also on the interpretation of the signais delivered by the different optical diagnostics that can be used for aerosol metrology. In particular, this work aims to evaluate the relevance of the use of optical diagnostics to characterize soot particles in atmospheric conditions. In order to study the impact of organic compounds initially present in the particle or adsorbed in post-combustion on their radiative properties, we have studied soot produced by a diffusion flame (miniCAST) for different global richnesses and added an organic acid coating. In order to produce an oleic acid layer on reference particles, a coating device has been implemented and qualified. Particles thus generated, coated or not, were characterized in mass (TEOM measurements), in size (SMPS measurements) and morphologically (effective density). The coating thickness as well as the morphological restructuring caused by the addition of an organic coating was thus quantified. The radiative properties were measured by spectrally resolved light extinction and scattering (angular and spectrally resolved). A special effort was made to allow experimental measurements to validate pre-existing numerical results. Moreover, these different measurement techniques (optical and non-optical) have led to the generalization of the Rayleigh Debye Gans for Fractal Aggregates (RDG-FA) theory to particles of the polydispersed fractal aggregate type coated with an organic layer (RDG-CFA). This allows to understand phenomenologically the impact of a coating on the radiative properties and to permit an easier implementation in climate simulation codes or for the interpretation of optical measurements in the atmosphere. Finally, special attention was paid to the laser induced incandescence technique (LII), to study the applicability of this technique to organic particles or having interacted with atmospheric compounds during their aging processes.

Deformation of phospholipid vesicles in an optical stretcherDelabre, Ulysse, Feld, Kasper, Crespo, Eleonore, Whyte, Graeme, Sykes, Cecile, Seifert, Udo, Guck, Jochen 09 December 2019 (has links)
Phospholipid vesicles are common model systems for cell membranes. Important aspects of the membrane function relate to its mechanical properties. Here we have investigated the deformation behaviour of phospholipid vesicles in a dual-beam laser trap, also called an optical stretcher. This study explicitly makes use of the inherent heating present in such traps to investigate the dependence of vesicle deformation on temperature. By using lasers with different wavelengths, optically induced mechanical stresses and temperature increase can be tuned fairly independently with a single setup. The phase transition temperature of vesicles can be clearly identified by an increase in deformation. In the case of no heating effects, a minimal model for drop deformation in an optical stretcher and a more specific model for vesicle deformation that takes explicitly into account the angular dependence of the optical stress are presented to account for the experimental results. Elastic constants are extracted from the fitting procedures, which agree with literature data. This study demonstrates the utility of optical stretching, which is easily combined with microfluidic delivery, for the future serial, high-throughput study of the mechanical and thermodynamic properties of phospholipid vesicles.

Renderingstidsjämförelse mellan One-way data bindning, Virtual DOM och Two-way data bindning, Real DOM inom e-handel / Rendering time comparison between One-way data binding, Virtual DOM and Two-way data binding, Real DOM in e-commerceÖstholm, Caroline January 2023 (has links)
Under de senaste åren har webbapplikationsarkitekturen utvecklats för att möta webbapplikationsanvändarnas krav på sömlösa användarupplevelser (Aggarwal & Verma, 2018). Teknikval och ramverk påverkar prestandan för e-handelswebbplatser vilket i sin tur påverkar användarupplevelsen och e-handelsföretagens lönsamhet (Camilleri, 2021). Ett tekniskt experiment genomfördes för att jämföra teknikkombinationerna One-way data bindning, Virtual DOM och Two-way data bindning och Real DOM för ramverken ReactJS och Angular. Resultatet från de olika mätserierna visade på att hypotesen om att ReactJS med dess teknikkombinationer har en snabbare renderingstid, endast stämmer när en (1) produkt renderas ut i kundvagnen. Men när fler produkter renderas ut i kundvagnen falsifieras hypotesen då Angular med dess teknikkombinationer har en snabbare renderingstid. För framtida arbete skulle ytterligare mätningar behöva genomföras där fler antal produkter testasför att se vart gränsen går för teknikvalen utifrån antalet renderade element, men också att genomföra mätningar i fler webbläsare.

Validation of a new iPhone application for measurements of wrist velocity during actual work tasks / Validering av en ny iphone-applikation för mätning av handledshastighet under verkliga arbetsuppgifterAbaid, Mohammed Abderhman January 2023 (has links)
The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. Therefore, there is a need to develop user-friendly risk assessment methods for wrist angular velocity measurements. This master thesis aimed to validate the accuracy of a newly developed iPhone application (App), "ErgoHandMeter," for wrist velocity in actual work tasks, by comparing the “ErgoHandMeter” to standard electrogoniometers. The project study was performed with four participants, two females and two males, from three jobs performing actual work tasks. The total angular velocity obtained by the mobile application was compared with the angular velocity data from the standard electrogoniometer. The total angular velocities obtained from the smartphone and the goniometer were computed at the 10th, 50th and 90th percentile for the four subjects. The 50th percentile of goniometer-flexion velocity (G-flex) was 7.4 ± 5.4°/s, for the goniometer-total (G-tot) 8.7 ± 6.5)°/s and for App 7.2 ± 4.9°/s. The correlation coefficient for the 50th percentile of goniometer-flexion (G-flex) parameter and smartphone application was 0.994. For the goniometer-total (G-tot) and the application, it was 0.993. In a Bland-Altman plot the mean difference between G-flex and App for the 50th percentile was -0.18 °/s and for G-tot and App was -1.54 °/s, i.e. the App was lower in average. The limit of the agreement between G-Flex and App, and G-tot and App stayed within two standard deviations. For G-Flex and App (mean+1.96SD) was 1.34 °/s, (mean-1.96SD) was -1.71 °/s, while for G-tot and App (mean+1.96SD) was 1.89 °/s, (mean-1.96SD) was -4.96 °/s, indicating an adequate agreement between the two methods. A limitation was that the included occupations were all relatively low velocity. However, in conclusion, the results indicate that the two methods agree adequately and can be used interchangeably. / Genombrottet inom mobiltekniken och utvecklingen av smarttelefoner med sensorer som t.ex. tröghetsmätningsenheter (IMU) har gjort det möjligt att få exakta och tillförlitliga uppgifter om vinkelhastigheten för olika objekt. De tillgängliga tekniska sensorerna för handledsrörelser, t.ex. elektrogoniometrar, är dyra, tidskrävande och de samplade signalerna kräver ett särskilt datorprogram för att analyseras. Det finns därför ett behov av att utveckla användarvänliga riskbedömningsmetoder för mätningar av handledens vinkelhastighet. Syftet med detta examensarbete var att validera noggrannheten hos en nyutvecklad iPhone-applikation (App), "ErgoHandMeter", för handledshastighet i verkliga arbetsuppgifter, genom att jämföra "ErgoHandMeter" med vanliga elektrogoniometrar. Projektstudien genomfördes med fyra deltagare, två kvinnor och två män, från tre yrken som utförde verkliga arbetsuppgifter. Den totala vinkelhastigheten som erhölls av mobilapplikationen jämfördes med vinkelhastighetsdata från standardelektrogoniometern. De totala vinkelhastigheterna som erhållits från smarttelefonen och goniometern beräknades vid den 10:e, 50:e och 90:e percentilen för de fyra försökspersonerna. Den 50:e percentilen för goniometer-flexionshastigheten (G-flex) var i genomsnitt 7,4°/s och för goniometertotalen (G-tot) 8,7°/s. Korrelationskoefficienten (r) för den 50:e percentilen för goniometer-flexionsparametern (G-flex) och smartphone-applikationen var 0,994. För goniometer-total (G-tot) och applikationen var r 0,993. I en Bland-Altman-plot var den genomsnittliga skillnaden mellan G-flex och appen för den 50:e percentilen -0,18°/s och för G-tot och appen -1,54°/s (App var lägre än Gon). Medelvärdet för differensen mellan G-Flex och App och G-tot och App ligger inom två standardavvikelser. För G-Flex och App (medelvärde+1,96SD) var 1,34 °/s, (medelvärde-1,96SD) var -1,71 °/s, medan för G-tot och App (medelvärde+1,96SD) var 1,89 °/s, (medelvärde-1,96SD) var -4,96 °/s. Vilket tyder på en tillräcklig överensstämmelse mellan de två metoderna. En begränsning var att de inkluderade yrkena alla hade relativt låg hastighet. Sammanfattningsvis visar dock resultaten att de två metoderna stämmer väl överens och kan användas på ett utbytbart sätt.
