Résumé :

Abstract. Photogrammetry and Laser-Scanning are usually considered as complementary. Integration of these two observation methods has the potential to blend their individual advantages. The resulting benefit is likely to be higher in drone airborne mapping, which payload capacity (and thus the quality of the embedded IMU) is limited. Thus, the trajectory computed by the IMU is subject to important time-dependent errors: even if the global attitude is less adequate, it is self-coherent locally. For this reason, we propose a close integration of Photogrammetry with Laser-Scanning based on the correction of time-dependent error of the trajectory with the help of the image observations acquired by the camera. Apart from the trajectory, this hybridization requires optical correspondences between image and Laser measurements. Such full set of input data is rigorously fused together in a Bundle-Adjustment in order to better determine the trajectory, and thus the resulting point-cloud. The presented theory was practically evaluated in an airborne case against a reference solution.

Résumé :

In this study, zinc vanadate/reduced graphene oxide (Zn3V2O8/rGO) composite has been synthesized via a simple approach. Advanced characterization techniques (powder X-ray, scanning electron microscopy, energy dispersive X-ray spectroscopy and ultraviolet-visible (UV-vis) spectroscopy) have been used to authenticate the formation of Zn3V2O8/rGO composite. Subsequently, Zn3V2O8/rGO was applied as photo-catalyst for hydrogen generation using photo-catalysis. The Zn3V2O8/rGO photo-catalyst exhibited a good hydrogen generation amount of 104.6 µmolg−1. The Zn3V2O8/rGO composite also demonstrates excellent cyclic stability which indicated better reusability of the photo-catalyst (Zn3V2O8/rGO). This work proposes a new photo-catalyst for H2 production application. We believe that the presence of synergistic interactions was responsible for the improved photo-catalytic properties of Zn3V2O8/rGO composite. The Zn3V2O8/rGO composite is an environmentally friendly and cost-effective photo-catalyst and can be used for photo-catalytic applications.

Résumé :

2009 - 2010
La ricerca si applica allo studio di decorazioni compositive a matrice geometrica originate dalle mutevoli combinazioni di forme elementari: la divisione regolare del piano con forme chiuse che lo ricoprono completamente, senza sovrapporsi e senza mai lasciare spazi vuoti. Operando su di esso, si inizia a quantificarlo, individuando ogni sua singola parte: la misurazione conduce alla scomposizione in forme elementari di figure complesse. Nello sviluppo di tali configurazioni, il problema della replica è sempre presente, dalla mera idea progettuale fino alle azioni di restauro, in quanto dalla ripetitività delle singole parti – fondamento del suo stesso esistere – prende origine l’intera composizione. Si è cercato, quindi, a partire da un’attenta analisi delle leggi simmetriche che dettano le logiche generative del disegno ornamentale, per una ben precisa canonizzazione di temi e motivi, di identificare gli schemi geometrici che consentano il controllo razionale della decorazione tramite l’individuazione dei procedimenti della iterazione in serie. Non si restituisce semplicemente il dettaglio così come ci appare, ma la scomposizione teorica dell’opera permette di individuare, nella successiva ricomposizione grafica, la natura e la posizione di ogni singolo elemento: uno sguardo critico che guida a una corretta e realistica riproduzione. I modelli formali tendono a divenire così modelli geometrici, simbolo di una struttura più profonda, che è possibile cogliere con l’aiuto di precisi schemi topologici. Attraverso i casi studio esaminati, ed in particolare in funzione del sistema decorativo riscontrato, è stato possibile individuare procedure metodologiche di rilievo ritenute idonee ad esplicitare il processo geometrico di base al fine di facilitare la successiva fase di replica sia in ambiente digitale che fisico e di favorire una funzionale sistematizzazione dell’ornato. In particolare si è ricorso ad un’innovativa metodologia, detta di photo scanning, che permette l’acquisizione simultanea di nuvole di punti e di texture. E così, nota la legge armonica che domina l’intera composizione, definita dal movimento rigido di un modulo predefinito su di un reticolo piano, la decorazione può facilmente riprodursi partendo dalla semplice unità quale entità che può essere, con l’utilizzo di macchine a controllo numerico, reiterata meccanicamente. La procedura è stata applicata a casi studi idonei per analizzare i principi della ripetibilità in serie e delle operazioni di laboratorio; ciò ha consentito, grazie alla ri-progettazione digitale e alla produzione con gli strumenti della tecnologia a controllo numerico, di codificare la riproducibilità tecnica, immateriale e materiale, del decoro architettonico. Le procedure e le strumentazioni descritte possono essere un potente metodo per il controllo, la verifica e il monitoraggio del decoro architettonico, permettendo di realizzare database metrici interattivi in grado di fornire in qualsiasi momento informazioni sull’oggetto rilevato. Impostare un modello di schedatura dei rivestimenti geometrici costituisce uno strumento di catalogazione funzionale sia alla tutela e alla fruizione del bene immobile, sia alla definizione di un metodo di approccio allo studio dei gruppi di simmetria. Si sarà così in grado di stabilire l’origine degli schemi decorativi, i percorsi di distribuzione, lo sviluppo di tendenze locali. [a cura dell'autore]

Résumé :

It was found that laser modified wood surfaces can be bonded together to create a wood composite without the need of any additive. This bonding method removes the need of applying adhesive, potentially lowers cost, and eliminates off gassing of petroleum resins, creating a wood product with many eco-friendly attributes. This body of work outlines a) initial chemical analysis of the laser modified surface b) its bond strength and c) the optimization of factors that control the strength of the bond. Surface chemical analysis on laser modified wood was conducted using photo acoustic Fourier transform infrared spectroscopy (PA-FTIR) and X-Ray photoelectron spectroscopy (XPS). Light microscopy and scanning electron microscopy were utilized for surface topology analysis.Differential scanning calorimetry (DSC) quantified the thermal properties of the modified wood surface. Screening of multiple factors that would contribute to surface modification and adhesion was performed utilizing mechanical testing. Optimization of significant factors that affect bond strength was determined statistically utilizing a design of experiment approach. Chemical analysis of the laser modified surface revealed changes in the carbonyl and aromatic regions indicating modification of the hemicellulose and lignin components, intensifying with increasing laser modification.The C1/C2 ratios found via XPS revealed that one or more of the following is occurring: more extractives have moved to the surface, condensation reactions among lignin units, and the loss of methoxy and breakage of aryl ether linkages occurred.Microscopy images showed color changes to a darker caramel color with a smoothing of surface topology, suggesting the occurrence of the softening and/or melting of wood polymers. DSC verified chemical and/or physical changes in the wood with the modified material now having a glass transition temperature between 130-150°C.DOE found that laser parameters (power and focus) as well as hot press parameters (temperature and pressure) were significant in optimizing the bond. The impact of the study is the first documentation of the ability to laser modifies wood surfaces and subsequently bond them together. The ability of the wood polymers at the surface to undergo flow at elevated temperature is implicated in the adhesion mechanism of the laser modified wood.

Résumé :

La mise en place, l'étalonnage et l'utilisation d'un nouveau banc expérimental basses températures basé sur une technique photothermique appelée photo pyroélectricité (PPE) sont décrits dans ce manuscrit. Les échantillons que nous avons étudiés en utilisant ce nouvel instrument sont le glycérol, le 1,2 propanediol et leurs mélanges binaires avec l'eau. Ce sont des cryoprotecteurs bien connus (CPAs) utilisés dans la cryoconservation, qui est une technique de préservation des cellules et tissus vivants en les refroidissant à des très basses températures. Le but ultime de la cryoconservation est d'éviter ou de maîtriser la formation de glace et d'atteindre un état vitreux ou amorphe. La vitesse de refroidissement, de chauffage et la concentration des CPAs utilisés sont les paramètres clés qui déterminent la formation de la glace. Par conséquent, l'étude des propriétés thermiques, en particulier près de la transition vitreuse (Tg) des solutions binaires des CPAs avec de l'eau est très importante pour comprendre leur comportement lors du refroidissement. La PPE a été utilisée pour étudier l'effusivité et le temps de relaxation ∝ caractéristique de la transition vitreuse. Le Tg et la fragilité (m) ont été déterminés à partir des données de la PPE en utilisant le modèle d'Havriliak Negami. L'état vitreux présente une très grande viscosité, de l'ordre de 10¹² Pa.s au voisinage du Tg. Le Tg et m peuvent être calculés à partir de l'évolution de la viscosité en fonction de la température ou par calorimétrie différentielle à balayage (DSC). Ainsi, des études à l'aide de ces deux techniques ont été menées et les résultats ont été comparés avec les données de la PPE
The construction, calibration and application of a new low temperature instrument based on a photothermal technique called photo pyroelectricity (PPE) is described in this manuscript. The samples we studied using the new PPE instrument were glycerol, 1,2 propanediol and their binary mixtures with water. These liquids are well known cryoprotectants (CPAs) used in cryopreservation, which is a technique to preserve the living cells and tissues from biological degradation by cooling to sub zero temperatures. The ultimate goal in cryopreservation is to avoid or control the ice formation and attain a glassy or amorphous state.The rate of cooling and heating and the concentration of the CPAs used are the key parameters that determine the ice formation. Therefore, studying the temperature dependent thermal properties especially near their glass transition temperature (Tg) of the binary solutions of CPAs with water at different concentrations are highly important to understand their behavior while cooling. The PPE technique was used to study the effusity and the ∝ relaxation time near the glass transition phenomenon. The Tg and fragility (m) were determined from the PPE data using the Havriliak Negami model. The glassy state has a characteristic property of very high viscosity, of the order of 10¹² Pa.s at Tg. The Tg and m can be calculated from the temperature evolution of viscosity or from Differential Scanning Calorimetry (DSC) measurements. Therefore, viscosity and DSC studies were conducted on the samples and were compared with PPE data

Résumé :

Light-addressable potentiometric sensors (LAPS) and scanning photo-induced impedance microscopy (SPIM) have been extensively applied as chemical sensors and biosensors. This thesis focuses on the investigation of LAPS and SPIM for electrochemical imaging based on two different semiconductor substrates, silicon on sapphire (SOS) and indium tin oxide (ITO) coated glass. Firstly, SOS substrates were modified with 1,8-nonadiyne self-assembled organic monolayers (SAMs), which served as the insulator. The resultant alkyne terminals provided a platform for the further functionalization of the sensor substrate with various chemicals and biomolecules by Cu(I)-catalyzed azide alkyne cycloaddition (CuAAC) 'click' reactions. The CuAAC reaction combined with microcontact printing (μCP) was successfully used to create chemical patterns on alkyne-terminated SOS substrates. The patterned monolayers were found to be contaminated with the copper catalyst used in the click reaction as visualized by LAPS and SPIM. Different strategies for avoiding copper contamination were tested. Only cleaning of the silicon surfaces with an ethylenediaminetetraacetic acid tetrasodium salt (EDTA) solution containing trifluoroacetic acid after the 'click' modification proved to be an effective method as confirmed by LAPS and SPIM results, which allowed, for the first time, the impedance of an organic monolayer to be imaged. Furthermore, the 1,8-nonadiyne modified SOS substrate was functionalized and patterned with an RGD containing peptide, which was used to improve the biocompatibility of the substrate and cell adhesion. By seeding cells on the peptide patterned sensor substrate, cell patterning was achieved. Single cell imaging using LAPS and SPIM was attempted on the RGD containing peptide modified SOS substrate Finally, an ITO coated glass substrate was used as a LAPS substrate for the first time. The photocurrent response, the pH response, LAPS and SPIM imaging and its lateral resolution using ITO coated glass without any modification were investigated. Importantly, single cell images were obtained with this ITO-based LAPS system.

Résumé :

L’intérêt croissant pour l’étude de la morphogénèse des côtes à falaises a permis de mieux appréhender les environnements méso/macrotidaux, mais en délaissant les environnements microtidaux. Pour cette raison, nous proposons d’étudier, à partir d’une approche exploratoire multi-échelle, la dynamique érosive des côtes à falaises en Méditerranée à travers l’exemple de la région Provence-Alpes-Côte d’Azur. Le choix de ce territoire s’est justifié en réponse à une problématique relative à la gestion des risques côtiers identifiée par le Conseil-Régional-PACA qui a financé ce travail doctoral. Les principaux objectifs visent à caractériser d’une part l’ampleur relative des occurrences érosives en fonction de la variabilité temporelle des forçages météo-climatiques, et d’autre part le degré du contrôle géologique sur la morphologie côtière. Toute la difficulté de l’étude réside donc dans l’optimisation des fenêtres d’observation afin de distinguer les comportements érosifs. Nous proposons donc de tester l’apport de quatre méthodes permettant de définir si l’érosion se produit de manière (1) continue à l’échelle annuelle (levés LiDAR embarqués depuis un bateau), (2) chronique à l’échelle séculaire (orthophotographies aériennes) et (3) exceptionnelle voir (4) catastrophique sur les temps propres à l’Holocène et au Quaternaire (datations aux cosmogéniques in situ 36Cl et analyses morphométriques). Au regard des résultats mesurés et interprétés, il apparaît que l’activité gravitaire produite au cours du XXe siècle (érosion moyenne de l’ordre du cm.an-1) est très faible par rapport aux environnements méso/macrotidaux
Increasing interest in studying rocky cliff coastline morphogenesis allowed a better understanding of meso/macrotidal environments, but let microtidal environments apart. Thus we propose studying the dynamic of cliff coastlines erosion in Mediterranean in the South-East of France, through a multi-scale explorative approach. This doctoral work was supported by the region Provence-Alpes-Côte d’Azur, which identified a problematic in relation with coastal hazard management. The main objectives aim at characterizing on one hand how the temporal variability of meteorologic and climatic forcings affects the magnitude of erosion, and on other hand to which extent the geological setting controls the coastline morphology. The great challenge of this work therefore consists in optimizing the observation range in order discriminate erosive behaviours. Thus we propose assessing the contribution of four methods in determining whether erosion takes place (1) continuously at annual scale (boat-borne laser scanning surveys), (2) chronic at secular scale (aerial orthophographies)and (3) exceptional even (4) catastrophic over the characteristic timescales of Holocene and Quaternary (cosmic ray exposure dating from in-situ 36Cl and morphometric analysis). The interpretation of the results shows that erosion rate observed through the XXth century (order of magnitude of cm.y-1) is very low compared to meso/macrotidal environments. However at timescales ranging from pluri-secular (0.29 ka BP) to pluri-millenar (6.8 ka BP), exceptional storms surges of +3 NGF could initiate an erosion process resulting in the formation of horizontal shore platforms

Résumé :

Jádrem této disertační práce bylo studovat optické a elektrické charakteristiky tenkovrstvých elektroluminiscenčních součástek řízených střídavým proudem (ACTFEL) a zejména vliv procesu stárnutí luminiforů na jejich optické a elektrické vlastnosti. Cílem této studie měl být příspěvek ke zvýšení celkové účinnosti luminoforů, vyjádřené pomocí jasu, účinnosti a stability. Vzhledem k tomu, že současnou dominantní technologií plochých obrazovek je LCD, musí se další alternativní technologie plošných displejů porovnávat s LCD. Výhodou ACTFEL displejů proti LCD je lepší rozlišení, větší teplotní rozsah činnosti, větší čtecí úhel, či možnost čtení při mnohem vyšší intenzitě pozadí. Na druhou stranu je jejich nevýhodou vyšší energetická náročnost, problém s odpovídající barevností tří základních barev a podstatně vyšší napětí nutné pro činnost displeje. K dosažení tohoto cíle jsme provedli optická, elektrická a optoelektrická měření ACTFEL struktur a ZnS:Mn luminoforů. Navíc jsme studovali vliv dotování vrstvy pomocí KCl na chování mikrostruktury a na elektroluminiscenční vlastnosti (zejména na jas a světelnou účinnost) ZnS:Mn luminoforů. Provedli jsme i některá, ne zcela obvyklá, měření ACTFEL součástek. Vypočítali jsme i rozptylový poměr nabitých barevných center a simulovali transportní charakteristiky v ACTFEL součástkách. Studovali jsme vliv stárnutí dvou typů ZnS:Mn luminoforů (s vrstvou napařenou či získanou pomocí epitaxe atomových vrstev) monitorováním závislostí svítivost-napětí (L-V), velikost vnitřního náboje - elektrické pole luminoforu (Q-Fp) a kapacitance-napětí (C-V) ve zvolených časových intervalech v průběhu stárnutí. Provedli jsme krátkodobá i dlouhodobá měření a pokusili jsme se i o vizualizaci struktury luminoforu se subvlnovým rozlišením pomocí optického rastrovacího mikroskopu pracujícího v blízkém poli (SNOM). Na praktickém případu zeleného Zn2GeO4:Mn (2% Mn) ACTFEL displeje, pracujícího při 50 Hz, jsme také studovali stabilitu svítivosti pomocí měření závislosti svítivosti na napětí (L-V) a světelné účinnosti na napětí (eta-V). Přitom byl zhodnocen význam těchto charakteristik. Nezanedbatelnou a neoddělitelnou součástí této práce je i její pedagogický aspekt. Předložený text by mohl být využit i jako učebnice pro studenty na mé univerzitě v Lybii.

Résumé :

More and more studies have been conducted in the field of architectural survey: the development and the optimization of new technologies, are greatly expanding the range of application, reaching more properly engineering areas. Strong standardization of infographics technologies the way of restitution of the artifacts is changing: no more - and not only - bi-tridimensional productions, but conceptual analysis and representations that go beyond the simple “visual” aspect of the work on which we investigate. However, we encounter new and important problems about the standards to be followed and the reliability and compatibility of the implemented procedures and methodologies. The aim of this chapter is the definition of a documentation able to guarantee the scientific survey operations, a decay of the errors and an adequate graphical output, combining the direct survey to the photo scanning technique applying this methodology to the survey of Sant'Angelo Fasanella bridge in province of Salerno.

Résumé :

This chapter describes different methods and devices that can be used in optical scanning systems (OSS), especially applied to structural health and monitoring (SHM) in order to reduce the interference and losing of resolution in the measurements of the displacements and coordinates calculated by the OSS of a specific structure to be monitored. The principal parts of the OSS are a photo-detector, non-rotating emitter source of light, a DC electrical motor, lens, and mirror. All the measurements and experiments have been realized in a controlled environmental; the optical noise was simulated with a similar intensity than the intensity of the reference signal of the emitter source. Applying analogue filters has disadvantages because part of signal with important information for the performance of the system is removed, but particularly the components will often be too costly. However, there are digital filters and techniques of computational statistics that can solve these problems.

Résumé :

Developing 3D digital models of artefacts, monuments, excavations and historic landscapes as part of digital documentation is becoming common in the field of heritage management, virtual tourism, immersive Due to the present pandemic situation with restricted social distancing; gallery, library, archive, and museum (GLAM) industries are facing an incremental burden on both their income and visitor traffic, which is affecting their survival. As a way out, we can see some GLAM institutes are trying to expand their collections on digital platforms for showcasing and promoting virtual visits. Numerous online portals and repositories are evolving for archiving, sharing, and trading 3D models are also evolving to support this digital vibe. This chapter explains the basics of photogrammetry and its development workflow, including data acquisition (photo shooting), data processing and a few post-processing tools. visualisation and scientific research. Such 3D reconstruction or 3D data acquisition form a laser scanning process involves high costs, manual labour and substantial expertise. On the other hand, Image-based 3D modelling photogrammetry software offers a comparatively inexpensive alternative and can handle the task with ease. Besides, documenting heritage artefacts with free and open-source software (FOSS) in supporting photogrammetry is getting popular for quality data production.

Résumé :

As you walk into the current University of Wisconsin-Madison’s Department of Forest and Wildlife Ecology, on the second floor of Russell Laboratories, you’ll see it is a far cry from Leopold’s 424 Farm Place, next to the university cow barns. Even so, resting just outside the department’s office door is a handmade Leopold Bench—one of those simply designed pieces with crossed-plank legs holding up a plank seat and back. As the Environmental Protection Agency’s Landscaping site states: “To spy a Leopold bench in someone’s yard is to know something about the family who there resides. … Its form, resting alone under a tree or in congregation around a fire-pit, reminds us of Leopold’s thoughtfulness.” This handmade blond bench, though, is over a half-century old. It was a gift to the Professor from his department—and wood-burned into it are the names of Aldo’s secretaries and graduate students for him to remember them by, and now for us to do the same. The department, of course, has changed radically since Aldo unexpectedly left. It web page displays a photo of Aldo in the upper corner and lists twenty-two faculty members, four of whom are women (which he would have liked). The fields of expertise presented at first seem like Leopold methods and topics on steroids: forest biometry, forest genetics, molecular ecology, forest remote sensing, spatial analysis, modern climate change. Other specialties are perspectives he had already been integrating into his thinking and planning: landscape ecology, forest ecosystem ecology, tree physiology, forest and environmental history, conservation biology, land use/land cover change, hydrology, population dynamics, conservation management extension, resource policy, ecosystem management, society and natural resources. Scanning the expertise of the emeritus and affiliate faculty, you can see even further outgrowths of Leopold’s far-ranging, integrated thinking and imagining: forest pathology, natural resource and land economics, biogeochemistry, international forestry, development planning, recreation management, economic forecasting, forest soils, human behavior and resource management, nutrient and carbon cycling in forest, nursery, and urban ecosystems.
