Повний текст джерелаThis thesis work concerns the characterization effort within a cooperation project aiming at developing antimicrobial textiles for various application fields, particularly health applications and food-processing industry. The analytical approach combined different surface analysis techniques (microscopy techniques (SEM, AFM, TEM) and spectroscopy techniques (XPS, ToF-SIMS, SIMS, EELS)) to microbiological tests in order to understand the antimicrobial activity of deposits at the surface of textiles. Silver and Poly Hexamethylene Biguanide (PHMB) antimicrobial agents were deposited by plasma (PVD / PECVD) and padding, respectively. Specific constraints related to the application fields (hernia implants and clothing) were considered (minimum concentration in antimicrobial agent and resistance to industrial washing, respectively). Despite some ubiquitous contamination related to industrial processes, surface analysis techniques proved to be an essential help to develop these processes (deposit quality, influence of deposition conditions, influence of washing). Depending on the application fields, high sensitivity surface analysis at the extreme surface and in-depth distribution of the antimicrobial agent were essential to understand the antimicrobial properties of the deposits, which confirms the relevance of the multi-analytical approach used in this thesis work

Повний текст джерелаA special wafer bonding method called the Silicon Direct Bonding technique is
used to study the bonding of unipolar (n-type, <100> oriented) silicon wafers. The
primary objective of this thesis project is to find an optimum surface preparation technique
for subsequent silicon wafer bonding. Wafer cleaning and treatment methods are
investigated to understand the correlation between a high quality wafer surface and the
resulting high quality electrical conduction at the interface. Accordingly, in this project, a
preference for hydrophobic (less polar Si-OH surface) wafers is given to ensure a
minimized amount of oxide layer on the surface. Several key factors that govern the
quality of the wafer surfaces, such as the degree of hydrophobicity, HF etching time,
composition of HF etching solution and Dr water rinse, are examined with ellipsometric
and XPS measurements. An HF etching followed by a sputter etching has been selected to
pre-treat the wafer surfaces for bonding. A maximum allowable air exposure time (35
second) is also found which would allow bonding without significant re-growth of the
oxide layer. Bonding is performed under vacuum with a special mechanical fixture and the
resulting structures from a subsequent heat treatment process are examined with crack
propagation testing. Bond strength after annealing is sufficient to withstand a pull test,
however, with a 3 point bend testing, the crack propagated horizontally at the interface.

Повний текст джерелаTeknisk ytrenhet är ett obligatoriskt krav för många produktionslinor. Det är en del avkvalitetsstyrningsprocessen för att säkerställa att ytorna på de tillverkade komponenterna är friafrån föroreningar och är redo för nästa steg i produktionslinan. Projektet har tagit hänsyn till tvåolika krav relaterade till komponents renhet: för det första mäts renheten som föroreningsnivå påett prov och sedan bestäms partikelstorlekarna. En viktig faktor vid renhetsbestämning ärnärvaron av partiklar som är större än en viss gräns, som kallas de kritiska partiklarna, som måstedetekteras. Avhandlingen är inspirerad av ett problem SCANIA har (2018) i sinproduktionsanläggning i Södertälje, Stockholm. SCANIA har ett kvalitetskontrollsystem somanalyserar föroreningsnivån av få komponenter genom en tidskrävande process vilken tar timmaroch kräver dyra mikroskop, mänskligt ingripande och ett dedikerat mätrum i anläggningen. Syftetmed denna avhandling är att undersöka en alternativ teknisk renhetsövervakningsmetod genombildanalys av förorenade proverna. Med en enkel digitalkamera tas bilder på de förorenadeproverna, bearbetas och analyseras för att uppnå renhetsnivån och partikelstorleken på proven. Iöverensstämmelse med den nuvarande lösningen finns det möjlighet att implementera denföreslagna metoden i produktionslinan, vilket ger större samplingsfrekvens.

Повний текст джерелаThe purpose of this dissertation is to investigate the suitability of using a recently proposed computer processing algorithm - the watershed boundary technique for applications in computer vision systems, where on-line segmentation of the surface froth images in commercial flotation cells is required. In industrial flotation cells, the surface froth offers considerable visual information as to the grade and recovery in extraction and the concentration of minerals in raw ores. The individual bubbles that constitute the surface froth give rise to complex three-dimensional structures that are problematic to segment accurately and reliably by computer vision. Investigating an efficient technique to automatically and accurately extract these visual features in real time is therefore the main task of this research work. Past research work into this field has resulted in a number of different techniques and algorithms for the purpose of segmentation. However, these algorithms are often iterative and therefore quite slow. The technique described here is noniterative and therefore one with industrial real time processing implications. The results show that the watershed boundary technique provides a reliable method for the segmentation of surface froth structures. Minor errors which occur do not significantly influence the statistical parameters which can be determined from the segmented images. This technique is not only very successful in segmentation, but may also be implemented for real-time operation. This clearly leads to a viable new segmentation method.

Повний текст джерелаThis study was performed in the frame of the SMD-Tex Joint Doctorate project. The doctoral research activities were carried out in three mobility periods at POLITO (Italy), Ensait (France), and University of Soochow (China). This work aims to propose novel approaches for the production of biofunctional textiles. These products consist of textile fabrics which underwent special finishing treatments to confer properties that display beneficial effects to the user's health.In the last decades, pharmaceutical research has been investigating novel and more effective tools to administer a drug to the patient. The scope of these studies is to provide effective therapeutic dosages over a long time, minimizing the number of required administrations and the possible side effects. In this context, the skin has been regarded as a potential route for the release of local and systemic drugs. Such an approach is simpler and less invasive compared to other routes. Therefore, several strategies have been developed to effectively deliver drugs across the skin barrier. Among them encapsulation technology allows the incorporation of the active substances inside nanoparticles (NPs) to i) protect the drug, ii) effectively deliver it through the skin iii) control the release over time.In the present work, drug-loaded NPs were produced by employing polycaprolactone (PCL) as shell material. The produced nanoparticles were then used to finish cotton fabrics producing biofunctional textiles to be employed as wearable drug delivery devices. The flash nanoprecipitation technique (FNP) was exploited for the nanocarrier production being identified as a simple, sustainable and efficient production process. The suitability of the FNP process to produce NPs to be used in the preparation of biofunctional textiles was investigated. The PCL nanoparticles were produced by loading three different drugs in the system i.e. caffeine, melatonin, and curcumin. Such drugs are indeed considered model drugs in terms of hydrophilicity level. The latter is a key property in determining the outcome of the encapsulation process and the dermal permeation.The FNP process was run by dissolving the polymer in an organic solvent and making the solution stream collide against an antisolvent stream in a micromixer, resulting in the polymer precipitation in the form of nanoparticles. The drugs were precipitated together with the polymer upon being added either to the solvent or the antisolvent stream. For each active substance, the experimental protocols and analytical methods were adjusted to better investigated the drug-loaded NPs system. The effect of the formulation as well as the process parameters on the properties of the nanoparticles was investigated. The process was optimized to produce particles with a diameter lower than the one of skin pores. The amount of drug loaded in particles was investigated by loading capacity (LC) and encapsulation efficiency (EE). Furtherly, the NP formulations were characterized to obtain insights on their physical, chemical, and morphological properties by various analytical techniques.The particles were applied to the cotton fabric either by imbibition or impregnation methods. The effectiveness of the functionalization treatment was evaluated combining different analyses. The biofunctional properties were studied in terms of antioxidant activity, UV protection factors, and drug release. For the latter test, the Franz cell method was employed using either artificial and excised porcine skin membranes.The study showed that the FNP allows producing drug loaded PCL NPs for all the three investigated substances. The proposed finishing treatment allowed to effectively functionalize the fabric surface. The treated textiles allowed to effectively deliver the active principles to the skin with permeation profiles dependent on the drug properties. The nanoparticle finishing also imparted cotton antioxidant and UV protection properties

An optical differential detection technique for the surface plasmon resonance (SPR) sensing is proposed. In our system, we combine a method of differential detection and SPR technique. The measurement sensitivity of refractive index is about 10-5 RIU (Refractive Index Unit). There are several advantages like immediate detection and high sensitivity in our system. This technique can be applied to the small biological molecule interaction. It is expected to combine the biological molecule on bio-chip array for massive parallel screens.

The main purpose of Reverse engineering is reconstructing surface model from the real object. However, in the process of reconstructing surface model, surface connecting technique plays a decisive role, and it is hard to merge Free-from surface in traditional way, especially in complexity and irregular one. For the reason, made the traditional model Digitization by using Mathematics model is more exact and efficient, and comparing to traditional way, using CAD system to edit, design and analyze surface is easier and expeditious. This research focuses on constructing constant radius blending surface of two surfaces. It investigates the need of technique and theory in the process of constructing blending surface and the relation of trimming between blending surface and original surfaces. Trimmed surface represents the surface which has been trimmed, and then analyzing the quality of blending surface from the connecting position of blending surface and original surface and the continuity of slope. Such algorithms, including surface offset and intersection curve of surfaces and it also algorithms the timing and appropriateness of using each calculation.

According to the investigation report issued by the Water Resources Agency, Ministry of Economic Affairs, there exists continuous subsidence in the Changhua and Yunlin areas of Taiwan. This adverse situation has greatly degraded the performance of local land utilization and the livelihood of inhabitants. In order to effectively address this issue, one must monitor the changes of ground surface elevation, and the solution nowadays is the Interferometric Synthetic Aperture Radar (InSAR)technique which has the advantage of broad area coverage, high measurement accuracy, and all-weather operations. The Differential Interferometric Synthetic Aperture Radar (DInSAR) and Persistent Scatterers InSAR(PSInSAR) techniques take two or more SAR images collected from different times and viewing angles over the same geographical location into the interferometric processing where the phase differences and small changes between images are extracted to render the information on geographical changes. However, for areas where the density of stabilized radar wave scatterers is low, such as flat terrain or lush vegetation, due to few fixed structures, the DInSAR and PSInSAR techniques may not function satisfactorily. To alleviate this limitation, the present study improves the differential SAR interferometry where the SAR images are first processed using PSInSAR technique to determine Persistent scatterer candidates (PSC)and then the images are further processed using statistical analyses such as Kolmogorov-Smirnov test, Cramer-von Mises test, Anderson-Darling test and correlation coefficient to acquire Distributed scatterer candidates (DSC). By processing these scatterer candidates, the present study establishes ground subsidence displacement and velocity for the Tuku Township of Yunlin County using Sentinel-1A SAR satellite images of European Space Agency from 2016 to 2017.

Repeat-pass satellite Interferometric SAR(InSAR) is potentially a unique tool for low cost precise Digital Terrain Model(DTM) generation and large-coverage surface deformation monitoring. Differential InSAR(DInSAR) may be used to monitor centimeter-scale surface displacements over large geographic extents. However, the method has limitations set by temporal and geometric decorrelation and atmospheric inhomogeneities. We present a Persistent Scatterer(PS) InSAR method for analyzing episodic crustal deformation in non-urban environments. This method for identifying PS pixels in a series of interferograms is based primarily on coherence index and finds low-amplitude pixels with phase stability that are not identified by the existing amplitude-based algorithm. The model which considers linear velocity deformation and DTM error usually using a centre target’s range distance. This method is fit for a test area nearby a centre area, but it’s not suitable for Taiwan’s urban. Taiwan’s urban usually locate in side of SAR images, that let a centre area’s value see not suitable. We chose adaptable range distance instead the fixed value. Using this method, we identified a density of 4.1 PS/km2. Even for longer than 500 m baselines, the PSInSAR technique can help build land subsidence maps better than differential InSAR does.

In this study, a method of surface wave inspection is approached to detect an object’s surface condition. Surface wave inspection is performed by emitting ultrasonic waves along the surface of the object, and then according to the acquired property values of wave reflection, to determine whether if there is an existence of abnormal surface condition, for example, a fissure.During the employment of ultrasonic wave aiming to detect possible fissure, multiple reflective signals are returned and recorded. By analyzing these signals, formation of path composition by various waves is then formulated. Furthermore, these signals are proved to be a useful tool to double check for accuracy of the fissure height. By combining the results drawn from the above analyses, mean and standard deviation for multiple estimates are derived, as well as the confidence level. In conclusion, it follows from what has been said that, accurate fissure height derived from surface wave inspection is an applicable index for equipment safety and maintenance analyses.

Abstract Whether the skin is healthy or not, it has its unique veins, such as prematurely、irritable、wrinkle、twinge…., and even though they are in different forms, they have never been showed completely. “Rubbing film” is a technique which can more faithfully indicate the condition of the skin than SEM, for the reason that it does not have to have the procedure of gilding, but receive the message from the skin directly and turn it into an image. The quality of the image is as well as SEM, and with an easy reading procedure, the type of the skin can be discerned. This research also utilize “ Rubbing film” to reveal the skins that may be prematurely、irritable、wrinkle or twinge. Up to the present, image tools are unable to be the quantitative tools on skin researches; however, there is also a breakthrough of the defect by “Rubbing film”. It utilizes the different traits of skin as a statistical standard, and turns the standard into statistic figures, enables it to be appropriate for big or small scales and long-term or short-term researches, such as researches about the dermal difference before and after a laser surgery or long-term of using fruit acid. (This article will be described clearly in chapter 4) “Rubbing film” use polymer colloid as a sampling tool and the rubbing film can be preserved and collected for a long time after sampling, which is cannot be easily impaired. These traits are necessary terms for long-term or short-term researches. In addition, it is easy to operate, and its non-invasion trait can decrease all kinds of limit on the research. Therefore, it is very useful to the research about handling the variety of the skin which needs to be fast and accurate. As far as the dermal researchers are concerned, “ Rubbing film” is very persuasive、well-reconstructed、can be easily read and the researching result of quantification can be easily compared. Besides, it is highly objective、low cost, and it possesses an advantageous position which is superior to other tools. There are all kinds of apparatus of skin determination. In order to handle skin variety accurately, and to observe with our eyes directly, “Rubbing film” is a more convenience selection than SEM. If it can be collocate with other researching equipments, the credibility and proving power can exalt the result of the research.

SMC (Sheet Moulding Compound) is a kind of fiber reinforced plastic material. It has several features: such as high strength, light weight, and ease of forming. It has been applied to various areas, such as car body, pressure vessel, and so on. The surface of SMC may be flat or curved. Under good forming conditions, the smoothness of the surface can be properly controlled. A precision system to inspect the surface smoothness is also needed. The conventional method using profilemeter may very often scratch the surface of SMC. Besides, its speed is too slow to use. This thesis develops a non-contact measuring system for surface smoothness. By the use of a dual-axis scanner, a laser line can be projected onto the test piece, and scanned across the surface. A CCD camera is then employed to capture the image of the reflected line on a screen. The distortion of projected image can be related to the surface smoothness based on proposed mathematical model. Through image processing technique, the smoothness can be directly repressented by index value, and then classified by different grades.
