This paper describes the use of a printing circuit technology to generate hydrophilic channels in a filter paper. Pattern was first designed using Protel soft, and printed on a blank paper. Then, the pattern was transferred on a sheet copper using a thermal transfer printer. The sheet copper with pattern was dipped in a ferric trichloride solution to etch the whole pattern of the sheet copper. At last, the etched sheet copper was coated with paraffin, then with a filter paper and heated at the other side of the sheet copper with an electric iron. The melting paraffin penetrated full thickness of the filter paper and formed a hydrophobic “wall”. Colorimetric assays for the presence of protein and glucose were demonstrated in the paper-based device. The work is helpful for researching paper-based microfluidic devices for monitoring health and detecting disease.

The combustion characteristics of the mixtures, which are made from different proportions of paper mill sludge and coal, were studied by the thermogravimetric analysis (TG-DTG) at different heating rates. The results showed that there were obviously three temperature zones in the paper mill sludge combustion curves, which is respectively corresponding to two devolatilization stages and a fixed carbon combustion stage. In these stages, the weight of sludge was lost promptly. When the proportions of sludge – coal blends were rather different, ignition point obviously shifted to the larger proportions, and DTG curve was more closed to the larger proportions. During the combustion process of the mixture, the paper mill sludge and the coal had basically maintained their own devolatilisation characteristics. And the comprehensive combustion characteristic index S of sludge-coal blend declined, demonstrating that higher volatility had better combustion characteristics. As the heating rate and the proportions of coal increasing, total weight loss rate increased, while burnout index Cbraised.

Rich mineral paper (RMP) has the advantage of being energy efficient, clean and creating no pollution during its production processes, with low production costs, and enjoying naturally complete biodegradability, fully compatible with the emerging demands for energy efficient carbon reducing features and the trend for environmentally green solutions, so if this media can replace traditional paper uses to become a new print media, tremendous environmental efficacy can be expected. So this study aims to discuss the print quality performance characteristics of RMP applications in large print run offset printing operations. The study deploys True Experimental Study methodology, with use of the digital printing test target of Graphic Arts Technical Foundation (GATF), with flat offset printing on traditional coated paper and eco-friendly RMP, printing 800 sheets of each, with systematic random sampling of 35 samples for the study. Quality determinations rely on X-rite i1 Pro for elucidation of the printing quality characteristics for solid ink density, TVI, contrast, gray balance, and color gamut measurement. The results of this study indicate the KCMY solid ink density and contrast of the eco-friendly RMP were less than traditional coated paper; TVI value was higher than traditional coated paper; color gamut performance was less than the traditional coated paper. Optimal gray balance combination for RMP was determined as follows: 7% tone with C7M3Y4, 30% tone with C30M28Y26, 60% tone with C60M58Y5, and 80% tone with C80M76Y66. The study suggests that ink particularly suitable for RMP uses remains in need of development. Additionally, the study found that use of RMP in the paper machinery indicated transverse and longitudinal tensile strength is slightly inferior to the traditional coated paper, resulting in unsmooth surfaces post-printing, for which it is recommended that RMP makers should consider paper machinery structural aspects when pursuing future research on modifying solutions for greater printing efficacy with RMP.

The impact of coated paper printability for image quality on the high-fidelity digital printing was studied in this paper. Compared with the traditional printing technology, high-fidelity digital printing technology is more likely to expand the color gamut, maintain the original tone linear and produce vivid image. The performance of coated paper to a large extent determines the image quality. In order to get high-quality printed matters, the mechanism of the coated paper printability influencing on the performance on high-fidelity digital printing is need to be researched in-depth. The printability of coated paper was studied from several aspects in this paper, including the structural properties, roughness, optical properties, absorption etc, the relationships between these properties and printing color, dot reproduction performance were also studied. Based on the previous theoretical and practical studies, the printability evaluation system of coated paper on high-fidelity digital printing was established initially. On digital printing, accurate color management technology also affects the printing quality as the performance of coated paper, so the advanced color management technology was also used in the current study. The results showed that the pore structure and the absorbent of coated paper were the most important factors for affecting the printing quality, and the roughness and optical properties of coated paper also had a certain impact.

With the gradually maturing super-speed inkjet printing technology, people are pursuing steadier and higher speed as well as better quality presswork for the sake of increasing economic benefit. To provide an overview of the velocity fluctuation of the inkjet machine platform and the cyclical fluctuation of the incremental encoder, external clock and corresponding internal clock were applied separately to print the equally spaced lines under the same platform speed. Then a magnifier was used to measure distance between the lines, according to which the velocity fluctuation mentioned above can be obtained. Thus conclusion can be drawn from the fluctuation analysis that the velocity cycle of platform is 60mm, however, number of those produced by the incremental encoder is up to 3, including 60mm influenced by the platform, 300mm produced by the perimeter of encoders pressure wheel and 600mm produced by the circumference of dance roller. Furthermore, dance roller contributes more influence on narrow coated paper. Through this research, inkjet technician can do directional compensation for every factors to reduce the fluctuation.

The quality of product of manufacturing industries depends on dimension accurately and surface roughness quality. There are many types of surface defects and levels of surface roughness quality. Ironing process is one type of metal forming process, which aims to reduce the wall thickness of the cup-shaped or pipes products, thus increasing the height of the wall. Manually surface inspection procedures are very inadequate to ensure the surface in guaranteed quality. To ensure strict requirements of customers, the surface defect inspection based on image processing techniques has been found to be very effective and popular over the last two decades. The paper has been reviewed some papers based on image processing for defect detection. It has been tried to find some alternatives of useful methods for product surface defect detection of ironing process.

This paper presents the performance investigations of the spatial domain image watermarking for camera-captured images on different types of printers and printable materials. We examine the effects of our previous watermarking method based on the modification of image pixels on three types of printers, i.e. inkjet, laser and photo printers, and four different types of printing papers, i.e. uncoated, matte, glossy and semi-glossy papers. In the experiments, the DSLR camera is used as tool to capture the printed watermarked images, while the image registration technique based on projective transformation is used to diminish the RST and perspective distortions in the captured image. The performances in terms of extracted watermark accuracy at equivalent watermarked image quality on different types of printers and printing papers are measured and compared.

When we think of paper-folding, we usually think first of the name that is usually associated with it: origami. But in the field of architecture, origami is more than just imagining an animal or flower which is what this word usually brings to mind. In architecture, we extend the meaning to take in the real essence of the word – that of great structural and constructional loads. The basic unit of origami – the fold – allows us to start manipulating space and even to create space itself. Paper-folding, with its spatial modelling potential, is to three-dimensionality what drawing is to two-dimensionality. It is after all an ancient Japanese art which encapsulates the advantages of intuitive thinking and fast modelling, once the basic elements of folding are known. Heino Engel (2001) in his book “Structural Systems”, describes intensive studies on types of structures which derive from this systematization. And the architect Ming Tang often uses structures in his projects which clearly originate in the concept of origami, and he correlates these structures with sustainable materials. The architect Michael Hansmeyer manages to incorporate all the beauty of the action of folding with the help of a computer, where the final result is a shape that approaches a real application at an architectural level. Over time, there have been numerous people who have found a relationship between the harmony and proportions of paper-folding and their own studies and projects. What is missing is a single point where clear concepts on the possibilities of folding and the results of those who have experimented with it can be brought together. This cataloguing, which is being carried out in this Master’s dissertation, is intended to be a contribution to the design method in architecture, through which the architect may achieve spatial dexterity over a piece of paper.

This paper describes simulation of combustion characteristics under high ambient and high injection of biodiesel combustion by using CFD simulation. Diesel engine performance and emissions is strongly couple with fuel atomization and spray processes, which in turn are strongly influenced by injector flow dynamics. The principal objective of this research is to seek the effect of temperature and pressure on the spray characteristics, as well as fuel-air mixing characteristics. Experiments were performed in a constant volume chamber at specified ambient gas temperature and pressure. This research was continued with injecting diesel fuel into the chamber using a Bosch common rail system. Direct photography technique with a digital camera was used to clarify the real images of spray pattern, liquid length and vapor penetration. The method of the simulation of real phenomenon of diesel combustion with optical access rapid compression machine is also reviewed and experimental results are presented. The liquid phase of the spray reaches a maximum penetration distance soon after the start of injection, while the vapor phase of the spray continues to penetrate downstream. The condition to which the fuel is affected was estimated by combining information on the block temperature, ambient temperature and photographs of the spray. The increases in ambient pressure inside the chamber resulting in gain of spray area and wider spray angle. Thus predominantly promotes for a better fuel-air mixing. All of the experiments will be conducted and run by using CFD. The simulation will show in the form of images.
