Resumen
For the rational decision of colors on the different building objects it is recommended to use optimal colors to create the best climate at industrial enterprises. For this purpose the appropriate building codes are developed. Building constructions in the industrial enterprises, which are applied fire-retardant paint, also painted in the appropriate color with tinting paste, or applying the finishing coat with that color. It is shown, that the introduction of tinting paste in the fire-retardant paint as overcoating of the fire-retardant paint leads to chaotic effect on height of foam of the intumescing coatings. The conclusions about invalidity of coloring with the fire-retardant paints in saturated tones used tinting paste without preliminary testing on the fire retardant efficiency are made. Similar conclusions are applied to the paint systems for an intumescing fire protective coatings using surface finishing.

Resumen
Ocular prosthetics are mainly created to meet the aspect of esthetic consideration. The paint application in ocular prosthetics construction is remaining an option for Prosthodontist. This study aims to examine the effect of types of paint toward iris color change of the ocular prosthetics. Three black types of paint: oil paint (Maries Oil Color, China), automotive paint (Avian, Indonesia), and acrylic paint (Sakura, Japan) were used to paint paper disc to produce 27 iris ocular prosthetics. Chromameter was used to examine the first and the final color after acrylic processing using themicrowave. The measurement results in the process using Commission Internationale de l’Eclairage. One-way ANOVA test showed significant differences between the three types of paints on ocular prosthetics (p<0.05). The LSD test revealed that oil paint groups had more significant results than the automotive paint group and acrylic paint group, while the automotive paint group did not have significant differences with the acrylic paint group (p>0.05). Thus, it is conclusive that oil paint influences the iris color change of the ocular prosthetics.

Resumen
Painting using paint powder is one of the techniques of protection against corrosion are evolving rapidly. Powder paints have aesthetic value approaching liquid paint as well as durability and relative utilization is better than liquid paint. The process of maturation of the paint powder that is only done with the process of warming at a certain temperature and a certain span of time. Standard maturation process known as maturation curve (curing folder). The difference in temperature and time against standard value ranges of risk occurrence of color change especially in white color (light). Therefore, do the research to find out the influence of temperature and time of warming up against the tendency of yellowing in white powder paint. Colour measurement is performed using a colorimeter in units of CIE Lab. Value b in CIE lab color trend show the yellowish or bluish. Temperature and time of warming up is the variable factor research determined 5.Keyword : paint powder, maturation, temperature, color. Pengecatan menggunakan cat bubuk merupakan salah satu teknik perlindungan terhadap korosi yang berkembang secara pesat. Cat bubuk memiliki nilai estetika mendekati cat cair serta daya tahan dan utilisasi yang relative lebih baik dibanding cat cair. Proses pematangan cat bubuk yang hanya dilakukan dengan proses pemanasan pada suhu tertentu dan rentang waktu tertentu. Standard proses pematangan dikenal dengan kurva pematangan (curing map). Perbedaan suhu dan waktu terhadap rentang nilai standard menimbulkan resiko terjadinya perubahan warna khususnya pada warna putih (terang). Oleh sebab itu dilakukan penelitian untuk mengetahui pengaruh suhu dan waktu pemanasan terhadap kecenderungan menguning pada cat bubuk warna putih. Pengukuran warna dilakukan dengan menggunakan colorimeter dalam satuan CIE Lab. Nilai b pada CIE lab menunjukan kecenderungan warna kekuningan atau kebiruan. Suhu dan waktu pemanasan merupakan variabel penelitian yang faktornya ditentukan 5⁰C dan 5 menit diluar kurva pematangan. Kata kunci: cat bubuk, pematangan, suhu, warna.

Resumen
The effect of leaf color on alighting behavior of Edovum puttleri Grissell was examined in a laboratory sticky-board test. Paint models mimicking the leaf top colors of eggplant, potato, and tomato and a model mimicking average underside leaf color were tested in paired comparisons. The underside leaf color mimic was the most preferred; no significant differences in landing rates occurred among any of the three leaf top color mimics. The underside leaf color mimic also was tested against two gray shades sharing the same intensity of reflectance; no significant differences were detected. The parasitoid, therefore, preferentially alighted based on the intensity and not the hue of the models. For all assays, a significant departure from randomness was found because a higher percentage of females alighted on the paint models than that which was in the colony. This suggests that parasitoids were alighting in a search for host eggs.

Resumen
This study discloses a method for painting artwork using a CO2 laser. The continuous-wave laser beam, at a predetermined heat flux and a predetermined number of laser beam passes, mixes and displaces the plurality of colored polymer-based compositions, respectively, by way of melting and vaporizing them. Experiments showed a great accuracy of colors and designed patterns between the computer aided design (CAD) drawing and what was achieved after laser discoloration. It was found that lower values of power and speed provide sufficient energy and time to make a melt pool of colors and cause their vaporization from the surface. A detailed numerical simulation was performed to obtain a detailed understanding of the physics of laser interaction with paint using ABAQUS software. The comparative analysis indicated that the top layer of paint (including yellow and green colors) melted upon increasing cutting speed and employing one laser pass. For blue and red paints, two passes of lasers are required; in the case of red color, lower laser speed is also necessary to intensify the heat. This method can be applied for making art designs on each surface color because it is based on melting and vaporization using a laser.

Resumen
Recent advancements in single-molecule-based superresolution microscopy have made it possible to visualize biological structures with unprecedented spatial resolution. Determining the spatial coorganization of these structures within cells under physiological and pathological conditions is an important biological goal. This goal has been stymied by the current limitations of carrying out superresolution microscopy in multiple colors. Here, we develop an approach for simultaneous multicolor superresolution imaging which relies solely on fluorophore excitation, rather than fluorescence emission properties. By modulating the intensity of the excitation lasers at different frequencies, we show that the color channel can be determined based on the fluorophore’s response to the modulated excitation. We use this frequency multiplexing to reduce the image acquisition time of multicolor superresolution DNA-PAINT while maintaining all its advantages: minimal color cross-talk, minimal photobleaching, maximal signal throughput, ability to maintain the fluorophore density per imaged color, and ability to use the full camera field of view. We refer to this imaging modality as “frequency multiplexed DNA-PAINT,” or fm-DNA-PAINT for short. We also show that frequency multiplexing is fully compatible with STORM superresolution imaging, which we term fm-STORM. Unlike fm-DNA-PAINT, fm-STORM is prone to color cross-talk. To overcome this caveat, we further develop a machine-learning algorithm to correct for color cross-talk with more than 95% accuracy, without the need for prior information about the imaged structure.

Both color keyed and color specific liquid primers have been used successfully in automotive paint application, reducing the use of costly topcoat materials. Generally, color keyed primer is close in color to the topcoat and is applied to the exterior surfaces of the vehicle body. Color specific primer identically matches the topcoat material color, and can be used as a replacement for topcoat on interior surfaces. Application of color powder paint primer would provide for additional cost savings, more environment-friendly manufacturing, and higher customer satisfaction. Recent technology breakthroughs have led to the technical feasibility of applying multicolor powder paint with full reclaim and therefore 100% material utilization. The field feasibility of applying multicolor powder paint in an automotive manufacturing facility is being assessed and validated by GM. More specifically, GM has developed the GM Canister Powder Paint Delivery System to meet the challenges of color powder paint application. In anticipation of multicolor powder paint application, GM is completing its Manufacturing Systems Qualification (MSQ) Process for the Canister System. Due to the newness of the enabling technology, GM is investigating all aspects of materials, process designs, facilities, operations, and people, for the implementation of color keyed/color specific powder paint primer into new GM paint shops. Similar to GM's MSQ Process, qualification requirements in the pharmaceutical and medical device industry attest to the importance of validation in the implementation of new manufacturing technology. Beyond its technical purposes, validation can serve as a bridge between development and operation. During development, formal and relational contracts with
(cont.) suppliers should be established to provide incentives for the supplier to perform throughout validation and commissioning. Involving the plant in validation along with suppliers is one means of education and thus empowerment, a key phase of organizational change as described by Professor Shoji Shiba. Leadership can use several change management techniques to help prepare the plant organization for operation of the new manufacturing technology.

Resumen
Graduate school has been a time of travel through experimentation. The journey has almost always been a search for materials and sources that match my need for working with the self-referential narrative within the framework of a process. Repeatedly, I would venture out and turn back, only to venture out again, packed with new materials and image sources, in search of a complete process. In retrospect, there have been no dead ends, only quenched curiosities that sometimes cleanly, often clumsily, lead one to the other. What is left is a series of explorations from which I can pluck similarities, clues to my core interests and methods. In the end, I believe I have found a place of clarity, where interests and process converge.

Resumen
Wooden railway sleeper inspections in Sweden are currently performed manually by a human operator; such inspections are based on visual analysis. Machine vision based approach has been done to emulate the visual abilities of human operator to enable automation of the process. Through this process bad sleepers are identified, and a spot is marked on it with specific color (blue in the current case) on the rail so that the maintenance operators are able to identify the spot and replace the sleeper. The motive of this thesis is to help the operators to identify those sleepers which are marked by color (spots), using an “Intelligent Vehicle” which is capable of running on the track. Capturing video while running on the track and segmenting the object of interest (spot) through this vehicle; we can automate this work and minimize the human intuitions. The video acquisition process depends on camera position and source light to obtain fine brightness in acquisition, we have tested 4 different types of combinations (camera position and source light) here to record the video and test the validity of proposed method. A sequence of real time rail frames are extracted from these videos and further processing (depending upon the data acquisition process) is done to identify the spots. After identification of spot each frame is divided in to 9 regions to know the particular region where the spot lies to avoid overlapping with noise, and so on. The proposed method will generate the information regarding in which region the spot lies, based on nine regions in each frame. From the generated results we have made some classification regarding data collection techniques, efficiency, time and speed. In this report, extensive experiments using image sequences from particular camera are reported and the experiments were done using intelligent vehicle as well as test vehicle and the results shows that we have achieved 95% success in identifying the spots when we use video as it is, in other method were we can skip some frames in pre-processing to increase the speed of video but the segmentation results we reduced to 85% and the time was very less compared to previous one. This shows the validity of proposed method in identification of spots lying on wooden railway sleepers where we can compromise between time and efficiency to get the desired result.

Resumen
In 21st century Scandinavia, the use of colored paint in the built environment has decreasedconsiderably. Instead, color changing LEDs can be found in many homes. In this thesis, an experimentwas set up to investigate how these two coloring methods differ and coincide with regards toemotional response and perception of materiality. Four cubicles, two painted and two colored bylight, were evaluated by ten participants. The painted cubicles were perceived as more material intheir appearance with regards to texture and color than their counterparts. A greater feeling ofnervousness, stress, and disorientation was felt in the light-colored cubicles as opposed to aheightened feeling of inspiration, excitement and calmness in the painted cubicles. Though it isimportant to remember the difference was not significant. In addition, preconceived connotations tothe color tone could be an influencing factor and so further studies on additional tones should beconducted. Lastly, benefits and drawbacks with the coloring methods were discussed.

Resumen
This project is an in-depth investigation on the impact of lighting, marking and paint schemes on the operational aspects of police vehicles. This investigation consisted of two phases that ultimately consisted of four experiments. An array of lighting and marking schemes were implemented on police vehicles in a variety of jurisdictions for evaluation. The study then investigated the change in the visibility of police officers, the public reaction to these schemes, and the operational impacts of these systems. The first phase of the project was a naturalistic observation study where the goal was to better understand how traffic behaved around traffic stops. Test vehicles were positioned in simulated traffic stops and patrol locations to determine how traffic behavior was affected by various configurations of police lighting and markings. Camera and radar systems were used to measure the changes in driver speed and when drivers responded to the move over law. Based on the results of the naturalistic studies, the impact of the lighting system on officer visibility was investigated in a controlled human factors test where the ability of a driver to see a police officer outside of their vehicle was measured in the presence of the lighting systems. The purpose of this interjected effort was to verify that the experimental schemes would not increase risk to law enforcement despite data from the first phase indicating the vehicles were more visible. A second part to that study evaluated conventional methods of bolstering an officer's visibility outside of their vehicle at night. The second phase took the findings of the first phase and implemented changes to several police vehicles from local and state agencies to be in operation for at least 18 months. This was to assess the rate of near-misses and crash rate to relate the vehicle changes to law enforcement safety. Additionally, rates of citations were assessed, and surveys offered an opportunity for law enforcement to provide their own feedback on the implementations. The lighting systems evaluated included a completely blue lighting system, an enhanced all blue lighting system with twice the light output, a red and blue system, and a single flashing blue beacon. In terms of markings, retroreflective markings along the side of the vehicle, a retroreflective contour line, chevrons on the rear of the vehicle and unmarked vehicles were evaluated. Finally, a variety of vehicle colors were used to investigate the impact of the base vehicle paint color. The results indicate that both the red and blue lighting system and the high output blue lighting system increase the distance at which drivers moved over significantly. In general, at least 95% of traffic attempted to merge away from an actively lighted police vehicle, when possible. In terms of the speed change, drivers began reducing their speed by approximately 600 m from the police vehicle. Similarly, the addition of retroreflectivity to the rear of the vehicle showed an additional benefit for causing drivers to move over sooner. However, these benefits came at a cost to the officer's visibility. When outside of their vehicle, the high output blue system significantly reduced officer detectability while the red and blue configuration only impacted detection distance by 3 meters. The investigation did find that these impacts could be overcome with retroreflective vests worn by the officers. In the second phase, a preference revealed by officers favored the red-blue configuration. They stated that this configuration provided greater comfort for them and less glare to approaching drivers. The study also revealed that the alternative configurations did not impact the operational activities of police authority.

This project evaluated how lighting, marking and paint schemes on police vehicles affected their visibility and how traffic responded to them. An observational study positioned police vehicles with alternative lighting and markings in simulated traffic stops and patrol locations to evaluate traffic behavior. Camera and radar systems were used to measure the changes in driver speed and when drivers responded to the Move Over law. A second study evaluated how the lighting systems on a police car affect the visibility of an officer at night in a traffic stop scenario. A followup experiment looked into methods for bolstering the visibility of officers at night through conventional implementations such as body worn LED lighting, the use of a retroreflective vest, or by using lighting on the police vehicle's light bar to increase illumination of the police officer. A third study took the findings of the previous experiments and outfitted 64 Virginia State Police vehicles for 18 months. Another 64 Virginia State Police vehicles participated in a control condition where no changes were made to their vehicles. Data collected included the rate of near-misses or crashes and the rates of written citations. Surveys were administered to each participating officer regarding their perception of safety and comfort and allowed their open feedback and suggestions. The lighting systems evaluated included a completely blue lighting system, an enhanced all blue lighting system with twice the light output, a red and blue system, and a single flashing blue beacon. In terms of markings, retroreflective markings along the side of the vehicle, a retroreflective contour line, chevrons on the rear of the vehicle, and unmarked vehicles were evaluated.

Resumen
A proteção de materiais com alto valor agregado contra as intempéries é de grande importância tecnológica e econômica. Atualmente, a principal defesa diante do desgaste natural destes materiais é o revestimento, seja inorgânico, orgânico ou metálico. Um revestimento pode atuar de diversas formas para proteger o material em questão, atuando como barreira física, metal de sacrifício ou proteção anódica. O desenvolvimento de revestimentos protetores de alta durabilidade e baixo custo é de suma importância para o crescimento da indústria e das cidades em todo o mundo. Diante disso, este trabalho estuda a degradação de quatro revestimentos orgânicos comerciais, de diferentes composições químicas e propriedades físicas, com o objetivo de interpretar os fenômenos que ocorrem durante os ensaios e investigar as falhas apresentadas ao longo do tempo. As análises foram realizadas com uma tinta epóxi branca, uma tinta poliuretânica branca, uma tinta alquídica branca e um verniz acrílico. Cada um dos revestimentos estudados possui um mecanismo diferente de formação do filme sobre o substrato escolhido, aço carbono, e, portanto, possui características individuais específicas. A degradação dos filmes orgânicos foi realizada com a exposição dos corpos de prova à radiação ultravioleta (UV), de forma natural e acelerada, a fim também de avaliar diferenças e o comportamento destes revestimentos As amostras em exposição natural permaneceram durante um ano em contato com radiações solares, umidade, chuva e variações de temperatura. Já as amostras em exposição acelerada foram ensaiadas em uma câmara de intempéries aceleradas de UV por até 2000 horas. A degradação dos filmes foi acompanhada durante todos os ensaios e analisada por diferentes técnicas de caracterização, tais como: DSC, FTIR, MEV, EDS, FRX, microscopia óptica, espectrofotometria de cor; ensaios mecânicos de impacto, flexibilidade, aderência, rugosidade, além de medições periódicas de espessura. Paralelamente, exposições prolongadas em câmara úmida e névoa salina foram realizadas como parâmetro de comparação. Os resultados demonstram que a tinta poliuretânica sofre menores variações de cor e brilho, após os ensaios de degradação e que o verniz acrílico é o mais afetado na maioria dos casos. A tinta alquídica sofreu alterações significativas em névoa salina, entretanto, teve melhoras em suas propriedades mecânicas após as exposições ao UV. Quanto à comparação entre o ensaio de degradação natural e o artificial, conclui-se que cada ensaio interfere de diferentes maneiras nas propriedades dos revestimentos.
The protection of materials with high added value against the weather has great technological and economic significance. Currently, the main defense against the natural wear of these materials is the coating, whether inorganic, organic or metallic. A coating can act in various ways to protect the material in question, acting as a physical barrier, sacrificial metal or anodic protection. The development of protective coatings of high durability and low cost is very important for the growth of industry and cities around the world. Therefore, in this work are studied the degradation of four organic coatings, with different chemical compositions and physical properties, in order to interpret the phenomena that occur during the tests and to investigate the failures presented over time. The analyses were performed with a white epoxy paint, a white polyurethane paint, a white alkyd paint and an acrylic lacquer. Each one of the studied coatings has a different mechanism of film formation on the chosen substrate, carbon steel, and therefore has specific individual characteristics. The degradation of the organic films was carried out by exposing the specimens to ultraviolet (UV) radiation, in a natural and accelerated way, in order to clarify their differences and establish comparisons. The samples in natural exposure remained for a year outside, in contact with solar radiation, humidity, rainfall and temperature variations The accelerated exposure samples were tested in a chamber of accelerated UV for up to 2000 hours. The films degradation were monitored during all the tests and analysed by different characterization techniques, such as: DSC, FTIR, SEM, EDS, FRX, optical microscopy, color spectrophotometry; mechanical impact tests, flexibility, adhesion, roughness, in addition to periodic thickness measurements. At the same time, prolonged exposures in humidity chamber and salt spray were performed as a parameter of comparison. The results demonstrate that the polyurethane paint undergoes smaller variations of its properties after the tests and that the acrylic varnish is the most affected in most cases. About the comparison between the natural and the artificial degradation test, it is concluded that each test interferes in different ways in the properties of the coatings.

Resumen
O dióxido de titânio, TiO2, é o pigmento branco mais importante na indústria de tintas devido à sua capacidade de refletir o espectro da radiação solar nas regiões do visível e do infravermelho. Ao refletir os comprimentos de onda da região do visível, o observador percebe a cor branca. A região do infravermelho é percebida pelo ser humano na forma de calor e a radiação ao ser refletida pelo pigmento diminui o aquecimento da superfície pintada. Neste trabalho foram investigados os aspectos morfológicos do TiO2 e avaliado o seu impacto nas propriedades ópticas de tintas base água. Quatro tipos de TiO2 foram utilizados, um de tamanho nanométrico, dois pigmentos comercias com diferentes tamanhos de partículas e o quarto obtido da calcinação do pigmento nanométrico. A calcinação objetivou a alteração da estrutura cristalina da fase anatase para rutilo do TiO2 nanométrico. Os pigmentos e carga (CaCO3) utilizados foram caracterizados através de análises morfológicas (tamanho e formato das partículas, estrutura cristalina, área superficial), absorção de óleo e espectroscopia de refletância difusa (regiões do ultravioleta, visível e infravermelho próximo). Foram produzidas tintas com diferentes teores de pigmentos (5%, 10%, 15% e 20%) As tintas foram caracterizadas através dos seguintes ensaios: viscosidade, espessura do filme seco, determinação de cor e brilho e espectroscopia de refletância difusa. Constatou-se que as propriedades ópticas das tintas são fortemente dependentes do tamanho de partícula do pigmento TiO2. A refletância da região do visível (400 a 700 nm) apresentou valores ótimos nas tintas produzidas com 15 e 20% dos pigmentos comerciais com tamanho médio de partícula entre 140 e 600 nm, produzindo um filme branco com elevada opacidade. A tinta com TiO2 nanométrico (15 a 60 nm para as partículas unitárias) apresentou baixos valores de refletância difusa nas regiões do visível e do infravermelho. As tintas produzidas com TiO2 calcinado, com elevado tamanho de partícula, refletiram mais eficientemente a região do infravermelho (700 – 2500 nm). O tratamento térmico do TiO2 nanométrico resultou num pigmento com tamanho de partícula adequado para aplicação de tintas reflexivas ao calor.
Titanium dioxide, TiO2, is the most important white pigment in coating industry due to its ability to reflect solar radiation spectrum in visible and infrared regions. When TiO2 reflects the light wavelengths in the visible region, the observer perceives the white color. The infrared region is perceived by human being in the form of heat and when the radiation is reflected by pigment decreases the heating of painted surface. In this work, the morphological aspects of TiO2 were investigated and evaluated their impact on optical properties of waterborne paints. Four types of TiO2 were used; one nanosized pigment, two commercial pigments with different particle sizes and the last one was obtained from the calcination of nanoparticles pigments. The main objective of calcination was to alter the crystalline structure of anatase phase to rutile phase of nanometric TiO2. The pigments and filler used (CaCO3) were characterized by morphological analysis (particle size distribution and shape analysis, crystalline structure, surface area), oil absorption and diffuse reflectance spectroscopy (ultraviolet, visible and near-infrared regions) Paints were prepared using different pigments concentrations (5%, 10%, 15% and 20%). The followings tests were carried out to characterize the paints: viscosity, dry film thickness, color and brightness determination and diffuse reflectance spectroscopy. It was observed that the optical properties of the paints are strongly dependent on TiO2 pigment particle size. The reflectance of the visible region (400 to 700 nm) showed better results in the paints produced with 15% and 20% of commercial pigment whose average particle size ranges were between 140 and 600 nm, producing a white film with high opacity. The paint with nanosized TiO2 showed lowest values of diffuse reflectance in visible and infrared regions. The paints formulated with calcined TiO2, pigment showing higher particle sizes, reflected more efficiently the infrared region (700 to 2500 nm). Thermal treatment of nanometric TiO2 resulted in a pigment with particle size suitable for application of heat reflective paints.

Resumen
Ce travail de thèse a contribué au développement d'un outil numérique multi-échelle capable de restituer l'aspect visuel de revêtements de peinture de carrosserie automobile à partir des caractéristiques physico-chimiques et des propriétés diélectriques des différents constituants de base ; l'objectif est la prédiction et la complète maîtrise de l'aspect visuel des matériaux. Dans cette étude, des nanoparticules d'hématite (variété α-Fe2O3), d'oxyde et d'hydroxyde de nickel de différentes formes et tailles ont été synthétisées par un procédé hydrothermal. Les particularités de ces particules en termes de morphologie, de taille et de structure ont été soulignées car elles sont susceptibles d'affecter ses propriétés diélectriques, et donc la couleur obtenue. La réponse diélectrique des particules a été mesurée par spectroscopie de pertes d'énergie des électrons (EELS). Dans un revêtement de peinture, les pigments, qui interagissent les uns avec les autres pour former des floculats, modifient la diffusion de la lumière et donc la couleur perçue. Au cours d'une deuxième phase, des revêtements de peinture « modèles », constitués de particules d'hématite dispersées dans une résine polymère, ont été élaborés. L'auto-organisation spatiale de ces nanoparticules au sein du revêtement a été décrite à partir d'images 2D enregistrées à différentes échelles d'observation. Sur la base des mesures diélectriques locales réalisées sur les nanoparticules et peintures « modèles » synthétisées dans le présent travail, des modèles aléatoires de matériaux hétérogènes ont alors été établis par le Centre de Morphologie Mathématique, pour générer une « microstructure diélectrique» 3D de ces revêtements. Sur la base de ces modèles morphologiques, les propriétés diélectriques effectives des revêtements ont été prédites; les fonctions diélectriques alors obtenues sont en bon accord avec les mesures macroscopiques réalisées par ellipsométrie
This work contributed to the development of a multi-scale numerical tool able to reproduce the visual appearance of coatings for motor vehicle bodywork from the physico-chemical characteristics and dielectric properties of various base constituents; the goal is the prediction and complete control of the visual appearance of materials. In this study, hematite nanoparticles (the α-Fe2O3 variety), nickel oxides and hydroxides of different shapes and sizes were synthesised using a hydrothermal process. The characteristics of these particles in terms of morphology, size and structure have been particularly emphasised since they are likely to affect the overall dielectric properties of the coating, and therefore the color obtained. The dielectric response of the particles was measured by electron energy loss spectroscopy (EELS). In a coating of automobile paint, pigments which interact with each other to form flocs alter the light scattering and therefore the perceived color. During a second phase, model paint coatings consisting of hematite particles dispersed in a polymer resin were developed. The volume self-organisation of nanoparticles in the coating has been described from 2D images recorded at different scales of observation. Based on our local measurements of the dielectric function at different scales of the nanoparticules and model paint that were synthetized in the present work, random models of heterogeneous materials were then established by a partner within the consortium to generate a "dielectric 3D microstructure" of these coatings. Based on these morphological models, effective dielectric properties of the coatings were predicted, and then satisfactorily compared with macroscopic measurements from ellipsometry

Resumen
Abstract In daily life, is very common to witness scenes in which it is necessary to obtain different ranges of colors in the paintings that are used either with water or oil. This range of colors comes from the fusion and homogenization of primary colors or tones. Frequently, the process of mixing and dosing are carried out by people who, by trial and error, determine the color desired by the user. Then, the quality and precision of the paint is affected and generate customer dissatisfaction, claims, waste, and low productivity. This article shows the design and start up process of an automatic mixer prototype that doses and mixes paint to create complex color shades by implementing a human-machine interface and a control stage and verification. Also, the results of this investigation shows the engineering process carried out to obtain a prototype of a functional, automatic, exact mixing machine and a homogenous and quality product that meets the customer’s requirements. Improvements that will can do and future work are included too.
