Abstract:

The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. The products decorated by In-Mold Roller are protected from water and fading. These kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate the potential use of combining In-Mold Roller with digital inkjet printing in 3D decoration, e.g. in personalized printing services. The study results found show that digital inkjet printing to the PET film and then transfer to the ABS, the solid ink densities (SIDs) of primaries would increase. The tone values increases (TVIs) from highlight and middle (around 0~60%) were generally higher than those in shadows. The shapes and sizes of color gamut were also varied according to different kinds of digital UV inkjet printing processes. Moreover, after transferred, the color gamut became smaller.

Abstract:

María Luz Morales pertenece a una generación de periodistas y escritoras recientemente descubiertas por los investigadores. Precursora del periodismo cultural, su prolífica obra la convierte en un referente en la historia del periodismo. El propósito de este trabajo es recopilar las crónicas tituladas Charlas publicadas en la sección «La Mujer, el Niño y el Hogar» de El Sol, además de estudiar su aportación a la modernización de la mujer por la vía de la cultura. Para ello se ha consultado El Sol entre 1926 y 1931 en la Hemeroteca Digital de la Biblioteca Nacional, revisado la literatura científica y efectuado un análisis de contenido. El análisis revela que, si bien los temas coinciden con los contenidos habituales de las revistas femeninas, sin embargo, difieren en el enfoque. El eje temático de las crónicas gira en torno a la literatura escrita por mujeres, literatura infantil, lectura, teatro y moda. La autora fomenta la promoción cultural de la mujer y reclama para ella una consideración intelectual de igualdad

Abstract:

As the infrastructure of the internet continues to expand, networked computational surveillance becomes an essential practice of territorial and biopolitical control. The feedback loop between information technologies and global structures of power creates new territorial and biopolitical regimes that sanction the mobility of people and information across Earth. These new ‘techno-territories’ lead to the emergence of new agents of power, who weave virtual and material worlds together in order to exercise control over these new spaces and the bodies that flow through them. This article discusses the emergence of ‘digital hunters’ as both subjects and objects of power through a discursive analysis of AZ: move and get shot (2011-2014) and The Virtual Watchers (2016), two artworks by Joana Moll based on research into crowdsourced surveillance systems at the US/Mexico border. Through a discussion of these projects I trace the emergence of digital hunting as a new practice of territorial control through networked images, as citizens are militarized through participatory architectures of surveillance and social media.

Abstract:

This research applies 3D mesh mold-flow analysis to analyze the SD (Secure Digital) card. It aims at temperature of the mold and plastic. The proper mold filling temperature is found by simulation analysis to improve the short shot situation, and seeks the cause of warping via various processed conditions. SD memory card clip has a big variation in thickness. Due to the bigger flow resistance the plastic is difficult to reach thinner portion, even hot plastic is also difficult to supply. The temperature of plastic goes down as a result of the cold mold cavity. Thus, the plastic does not reach certain portions before solidifying. The cooling system of injection machine was controlled by constant temperature oil cooling. This study explored the optimum injection condition by utilizing experiment to control the temperature of the plastic, the temperature of mold, the packing pressure process and so on. It is valuable to companies which utilize injection mold applications.

Abstract:

Purpose In this paper, the effects of the adhesive and curing agent contents on the tensile strength, bending strength, gas evolution and gas permeability of three-dimensional printed sand molds are studied. A strength model of the three-dimensional printed sand molds is proposed. The multi-material composite sand mold forming test is carried out. In addition, the mesostructure of the sand mold is studied. Design/methodology/approach The performances of three-dimensional printed sand mold such as tensile strength, bending strength, gas evolution and gas permeability are studied using the standard test methods. The mesostructure of the sand mold is studied by digital core technology. Findings A sand mold strength model based on the resin adhesive content, curing agent content and sand mold compactness are obtained. Two types of multi-material composite three-dimensional printed sand molds are proposed. An increase in the curing agent content in the sand mold widens the mesoscopic characteristic size distribution of the sand mold, and large-sized mesostructures appear, resulting in a decrease in the sand mold bearing capacity. Practical implications Process parameters that affect the performance of three-dimensional printed sand mold are revealed. The sand mold bearing curve provides a reference for the ultimate design of three-dimensional printed sand mold. Originality/value The paper deals with experimental work on the performance and mesostructure of multi-material composite three-dimensional printed sand mold with different contents of adhesive and curing agent. That gives a perspective on future designs of sand mold based on these principles.

Abstract:

The NI LabVIEW is a software for real-time data processing and it is widely used for process control in industry. It has a lot of additional libraries and modules which extend its functions and support its applications in many different areas. Vision Builder and Vision Assistant are modules in NI LabVIEW which support image acquisition and processing. These modules are used for the purpose of the current research in order develop an algorithm to analyze mold distribution in blue cheese. Eight trademarks of blue cheese are used for comparative analysis of mold distribution. Every sample is cut with special cheese slicer in order to evaluate its mold distribution. The samples are captured with digital camera and images are processed in NI LabVIEW environment. Coefficient of mold (ratio of pixels with mold to all pixels in cut surface of cheese) is calculated for nine regions of interest on every picture. This coefficient is used for statistical analysis of mold distribution. It is observed that cheese which have low quantity of mold are presented with non-even mold distribution and cheese which have high quantity of mold are presented with almost even mold distribution. The results show that the upgraded experimental setting could be successfully applied for mold distribution analysis of blue cheese and the LabVIEW environment and its software modules Vision Builder and Vision Assistant could be effectively applied for fast and accurate evaluation of mold quantity and distribution in blue cheese.

Abstract:

The microfluidics field is at a critical crossroads. The vast majority of microfluidic devices are presently manufactured using micromolding processes that work very well for a reduced set of biocompatible materials, but the time, cost, and design constraints of micromolding hinder the commercialization of many devices. As a result, the dissemination of microfluidic technology—and its impact on society—is in jeopardy. Digital manufacturing (DM) refers to a family of computer-centered processes that integrate digital three-dimensional (3D) designs, automated (additive or subtractive) fabrication, and device testing in order to increase fabrication efficiency. Importantly, DM enables the inexpensive realization of 3D designs that are impossible or very difficult to mold. The adoption of DM by microfluidic engineers has been slow, likely due to concerns over the resolution of the printers and the biocompatibility of the resins. In this article, we review and discuss the various printer types, resolution, biocompatibility issues, DM microfluidic designs, and the bright future ahead for this promising, fertile field.

Abstract:

In 21th century, the product upgrading becomes faster and faster. The development of varieties of production needs rapid manufacturing technology. The rapid fabrication of sand mold & core is the key of rapid casting. In this paper, the rapid manufacturing technology without pattern was applied to produce the complicated sand molds & cores of pump case. The digital precision forming technology without pattern casting was selected to mill the outer sand mold. And the Selective Laser Sintering (SLS) technology was used to print the sand core. So the complicated sand molds and cores were fabricated rapidly without pattern. As a typical digital manufacturing technology, the rapid manufacturing technology without pattern has a variety of benefits such as short cycle, low cost, flexibility and so on. The technology that combines the sand milling and SLS provides a high-efficiency method for the Single and small batch castings.

Abstract:

Expecting that media and/or digital technologies “do” things (Verbeek), we are called upon to take a stance on them, theoretically as well as practically. Media literacy represents one such stance—we are prodded to be literate about media—but there are others. To this extent media literacy is a lens through which we look at issues and that shapes what we see. This becomes particularly clear when we consider another lens, namely, that of media health. While media literacy suggests a rather pragmatic way of doing, making do with what is on offer, the image of media health dramatically alters the starting point: media are seen here as affecting us, even to the extent that we become sick and need to be cured. This image or model of media as somehow related to disease and health is developed in varying degrees of explicitness in the work of Bernard Stiegler and Marshall McLuhan among others. In this paper, we investigate the differences between the media literacy and media health models from a meta vantage point and ask how the lens determines how we view and understand certain problems in relation to media/technologies. We do this by deploying a metaphor ourselves, namely that of mold. Our models are molds. They are understood as a “frame or model around or on which something is formed or shaped,” but the connotations of fungal growth helping organic decay and of soil and earth are also at stake. Depending on which meaning we prefer, it might turn out that we do not need to choose between our molds/models: they are interconnected, like mold. On a more theoretical level, we link up the media literacy and media health approaches to two major strands in philosophy of technology, namely to the pragmatist/postphenomenological and transcendentalist/critical streams respectively.

Abstract:

Based on the principles of conventional oedometer tests, half mold consolidation apparatus which attained Chinese Patent Certificate of New and Practical Device was designed for non-saturated soil's micro-observation with axial drainage conditions. By half mold consolidation tests, we could get similar stress-strain curves at different water content, which could illustrate the feasibility of the new apparatus. Besides, on the application of DPDM (the digital photogrammetry for deformation measurement) technology, the deformation fields of the silty clay were analyzed under monotonic increasing load, which could obviously show the macro mechanics properties by digital image analysis. According to the distribution of deformation fields, the analyzing area could be divided into three parts from top to bottom sequence: soil in top area subsided with upper porous-stone in balance; the deformation in the central area was changing the most whereas there had always been inapparent changes near down porous-stone. Such study could put forward a new conception for the development of conventional soil tests, which could be helpful to further establish the theoretical constitutive model for silty clay.

Abstract:

The fast-growing incidence of skin cancer, especially melanoma, is the guiding principle for intense development of various digital image-capturing devices providing easier recognition of melanoma by dermatologists. Handheld and digital dermoscopy, following of mole changes with smartphones and digital analysing of mole images, is based on evaluation of the colours, shape and deep structures in the skin moles. Incorrect colour information of an image, under- or overexposed images, lack of sharpness and low resolution of the images, can lead to melanoma misdiagnosis. The purpose of our study was to determine the colour error in the image according to the given lighting conditions and different camera settings. We focused on measuring the image quality parameters of smartphones and high-resolution cameras to compare them with the results of state-of-the-art dermoscopy device systems. We applied standardised measuring methods. The spatial frequency response method was applied for measuring the sharpness and resolution of the tested camera systems. Colour images with known reference values were captured from the test target, to evaluate colour error as a CIELAB (Commission Internationale de l’Eclairage) ΔE*ab colour difference as seen by a human observer. The results of our measurements yielded two significant findings. First, all tested cameras produced inaccurate colours when operating in automatic mode, and second, the amount of sharpening was too intensive. These deficiencies can be eliminated through adjusting the camera parameters manually or by image post-production. The presented two-step camera calibration procedure improves the colour accuracy of captured clinical and dermoscopy images significantly.

Abstract:

In this essay the author discusses the benefits of introducing digital making tools into the glass artist’s practice-based research, both on a professional and student level. Using an example from his personal creative practice as a case study, the author outlines not only the practical benefits of using digital technology, but how when combined with traditional hot-worked glass techniques the synthesis can produce art objects that would otherwise be impossible using either digital or manual means alone. He argues that it is the possibility of inventing novel approaches to art making that can motivate glass artists and students to embrace digital means of making, rather than relying on appeals to practicality and efficiency alone. Includes a description of producing blown glass sculptures that combine fused water-jet cut sheet glass with traditional mold blowing and glass sculpting techniques.

What’s more, these kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate potential usages of combining In-Mold Roller with digital UV inkjet printing in 3D decoration, e.g. in personalized printing services. Study results found that when the coverage and the resolution of inkjet printing become higher, the SIDs will become higher as well. When transferred to ABS, SIDs in each combination will increase. Each combination of inkjet conditions, with the isolation of white ink, color differences are less variant. TVIs of white ink decrease 30% to 40% halftone and display in “M” type. In print contrast, C and K colors of each combination are better than M and Y colors. After transferred into print contrast, each combination of PC will be higher about 2 to5. When transferred to ABS, color variances of each combination are not huge, and color differences are about 3to5.

Abstract:

The mechanical properties of molded pulp materials are the basis of the structural optimum design of molded pulp products. Therefore, the correlations between Poisson’s ratio and fiber structure, molding process, and thickness were found for materials including wood pulp, bamboo pulp, sugarcane pulp, white mixed pulp, black mixed pulp, recycled corrugated board pulp, and recycled newspaper pulp by the uniaxial tensile test and digital image correlation method. The fiber structures of the selected molded pulp materials were investigated by scanning electron microscopy. The results revealed Poisson’s ratios of wood pulp, bamboo pulp, sugarcane pulp, white mixed pulp, black mixed pulp, recycled corrugated board pulp, and recycled newspaper pulp to be 0.169, 0.108, 0.202, 0.120, 0.166, 0.098, and 0.044, respectively. Microstructural investigation further revealed that Poisson’s ratios of molded pulp materials were related to the fiber structure and drying method. The pulp material dried outside mold under lower pressure and temperature had a smaller Poisson’s ratio, while that dried inside mold under higher pressure and temperature had a larger Poisson’s ratio. The layered phenomenon of the molded pulp materials was also found by scanning electron microscopy images: the outer layer was denser than the inner layer. These results can provide guidance for the numerical simulation analysis and optimal design of molded pulp products.

Abstract:

The rapid monitoring of total fungi, including air and surface fungal profiling, is an important issue. Here, we applied air and surface sampling, combined with digital image quantification of surface mold spots, to evaluate the contribution of surface fungi to airborne fungal concentrations. Cladosporium, Penicillium, Aspergillus, and yeast often appeared in the air or on wall surfaces during sampling. The indoor/outdoor concentration ratios (I/O ratios) demonstrated that the airborne concentrations of commonly found fungal genera outdoors were higher than those indoors (median I/O ratio = 0.65–0.91), excluding those of Penicillium and yeast. Additionally, the surface density (fungal concentration/area) of individual fungi showed no significant correlation with the airborne concentration, excluding that of Geotrichum. However, if a higher surface ratio (>0.00031) of mold spots appeared in the total area of an indoor environment, then the concentrations of Aspergillus and Geotrichum in the air increased significantly. Our results demonstrated that the airborne concentration of indoor fungi is significantly correlated with the outdoor concentration. A higher density of surface fungi does not necessarily contribute to a high fungal concentration in the air. In contrast to fungal density, quantification of the surface fungal area is recommended to assess the risk of surface fungi propelling into the air.

Abstract:

Three procedures for producing new ways to visualize landforms as maps or images derived from Digital Elevation Models (DEMs) are given. One procedure is used to create a highly detailed circular gray scale image from an azimuthal distribution. A second procedure utilizes the principles associated with x-ray tomography for the construction of a volumetric map from DEM cross-sectional ‘slices’. The conversion of a DEM to a Digital Distance Model (DDM) comprises the third procedure, to provide ‘side-looking’ views of the DEM in a variety of map formats including stereograms. DEMs generated from Mars Orbital Laser Altimeter (MOLA) data were used to produce illustrations utilizing the three procedures.

Abstract:

The camera shell is analyzed by using Finit Element Method (FEM) to judge reliability of the structure. Static structural and explicit dynamics analysis are conducted. The results provide valuable reference for the structural optimization design. Three schemes for injection mold are developed. Injection moulding process of the shell is simulated by applying Moldflow. The volumetric shrinkage, shrink mark index, total deformation, fill time and clamping force are analyzed. The results show that combining Moldflow with FEM method can not only shorten the construction period, but also ensure the molding quality.

Abstract:

One of the drawbacks of using 3D printers in educational environments is that the creation time of each piece is high and therefore it is difficult to manufacture at least one piece for each student. This aspect is important so that each student can feel part of the manufacturing process. To achieve this, 3D printers can be used, not to make pieces, but to make the molds that students use to create replicas. On the other hand, for a mold to be used to make several pieces, it is convenient to make it with flexible material. However, most used material for 3D printers (PLA) is very rigid. To solve this problem, this article designs a methodology that allows the use of low-cost 3D printers (most common in school environments) with flexible material so that each mold can be used to manufacture parts for several students. To print flexible material with low-cost printers, it is necessary to adapt the machine and the print parameters to work properly. This article analyzes the changes to be made with a low cost 3D printer and validates the use of molds in school environments. A pilot test has been carried out with 8 students of the subject of Typography, in the School of Art and Superior of Design of Tenerife. During the activity, the students carried out the process of designing a typography and creating digital molds for 3D printing with flexible material. The designs were made using free 3D modeling programs and low-cost technologies.

Abstract:

Abstract Micro structured optical plastics components are intensively used, i.e. in consumer electronics, for optical sensors in metrology, innovative LED-lighting, or laser technology. Injection molding has been proven successful for the large-scale production of these parts. However, the production of these parts still causes difficulties due to challenges in the molding and demolding of plastics parts created with laser-structured mold inserts. A complete molding of the structures often leads to increased demolding forces, which then cause a breaking of the structures and a clogging of the mold. An innovative approach is to combine physical vapor deposition (PVD)-coated, laser-structured inserts and a variothermal molding process to create functional micro structures in a one-step process. Therefore, a PVD coating is applied after the laser-structuring process in order to improve the wear resistance and the anti-adhesive properties against the plastics melt. In a series of molding trials with polycarbonate (PC) and polymethyl methacrylate (PMMA) using different coated molds, the mold temperature during injection was varied in the range of the glass transition and the melt temperature of the polymers. Subsequently, the surface topography of the molded parts was evaluated by digital three-dimensional laser-scanning microscopy. The influence of the molding parameters and the coating of the mold insert on the molding accuracy and the demolding behavior were analyzed. It was shown that micro structures created by ultra-short pulse laser ablation can be successfully replicated in a variothermal molding process. Due to the mold coating, significant improvements could be achieved in producing micro structured optical plastics components.

Abstract:

The purpose of this paper presents the optical properties of microstructure of lightguiding plate for micro injection molding (MIM) and micro injection-compression molding (MICM). The lightguiding plate is applied on LCD of two inch of digital camera. Its radius of microstructure is from 100μm to 300μm by linearity expansion. The material of lightguiding plate uses the PMMA plastic. This paper uses the luminance distribution to make a comparison between MIM and MICM for the optical properties of lightguiding plate. The important parameters of process for optical properties are the mold temperature, melt temperature and packing pressure in micro injection molding. The important parameters of process for optical properties are the compression distance, mold temperature and compression speed in micro injection-compression molding. The process of micro injection-compression molding is better than micro injection molding for optical properties.

Abstract:

In resin transfer molding, mold filling is governed by the flow of resin through a preform which is considered as an anisotropic porous media. The resin flow is usually described by Darcy's law and the permeability tensor must be obtained for filling analysis. When the preform is composed of more than two layers with different in-plane permeability, effective average permeability should be determined for the flow analysis in the mold. The most frequently used averaging scheme is the weighted averaging scheme, but it does not account for the transverse flow between adjacent layers. A new averaging scheme is suggested to predict the effective average permeability of the multi-layered preform, which accounts for the transverse flow effect. When the flow in the mold is unsaturated, the effective average permeability is predicted by using the predicted mold filling time and transverse permeability. The new scheme is verified by measuring the effective permeability of the multi-layered preforms which consist of glass fiber random mats, carbon fiber woven fabrics, aramid fiber woven fabrics. Fluid flow through the preform composed of more than two layers with different in-plane permeability shows different flow fronts between layers. The difference in the flow front advancement is observed with a digital camcorder. The predicted flow front is compared with the experimental results and shows a good agreement. It is expected that the effective average permeability can be used for modeling the resin flow through the multi-layered preform.

Abstract:

Integrating digital media into classroom practice requires consideration on many levels, how young people access and engage with digital media at the level of media, mode and genre is complex and may redefine how literacy practices in the classroom are perceived. Young people use digital media in their everyday literacy practices and a failure to embrace new technologies in the classroom may lead to a disjuncture between their everyday and college-assessed literacy practices. Following an analysis of communicative interactions that looked at multi-layered media, modes and their affordances, this paper offers insights from recent research. It looks carefully at the congruence and incongruences that exists between the two literacy practices with the aim to offer rich insights into meaning making in what are comparatively new, digital literacy practices. A major conclusion is that some assessment tasks do have congruence with young people’s everyday literacy practices but at times they either do not take account of the students ‘funds of knowledge’ (Moll et al.,1992) to the full which is likely to cause confusion and possible under performance.
