Irregular Shapes

The revolution in the printing industry started by digital printing has resulted in the introduction of personalised production of small runs, fast job changes and short deadlines. By introducing digital printing into mainstream and production focus, even for the largest printing machine manufacturers, a new era of the graphic industry has just begun. After these significant changes in the printing process, the following process of graphic production – post-press needs to be digitalised. The initial goal is to back up the possibilities of digital printing and enable it to be applied as widely as possible to its full potential. Postpress has become a bottleneck in the digital world. One of the analogous processes, which is the focus of improvement, is the cutting of graphic materials in irregular shapes in the process of creating packaging. The use of lasers enables the digitisation of the die-cut or partial cutting post-press process. Cutting of different shapes is obtained when the laser touches the substrate and where it evaporates at that moment. A thermal process accompanies this evaporation, that to a greater or lesser extent affects the substrate to be cut. The parameters that govern laser are the subject of this paper. The development of laser cutting technology has opened various possibilities for innovations in the graphic and printing industry. Since this is still considered as new technology, extensive researches on its options are essential to reach the full potential of this technology. This paper is going to analyse the overall characteristics and use of laser technology in the graphic industry by focusing on the processing of paper materials. Indispensible to mention are the advantages and disadvantages of this technology. There are a lot of comparisons among existing technologies developed for cutting graphic materials and paper. The importance of this topic is concerning all production phases of the graphic product – from processing the raw material to cutting the final product such as packaging. Regarding that, the scope of the laser processing of the graphic materials is reviewed. The paper gives suggestions for further research and experiments regarding this topic.

Moving Average Model

The technology used in the printing industry is currently growing rapidly. Generally, the digital printing industry uses raw materials in the form of paper production. The use of paper material with large volumes is clear badly in need of purchasing large quantities of paper stock as well. The purchase of paper stocks with a constant amount at the beginning of each month for various types of paper causes a buildup or lack of material stock standard on certain types of paper. During this time the purchase and ordering of raw materials only based on the estimates or predictions of the owner. In this paper proposed forecasting will be carried out in the digital printing industry by applying the ARIMA model for each type of raw material paper with the Palembang F18 digital printing case study. The ARIMA modeling applied will produce different parameters for each materials paper type so as to produce forecasting with the Akaike Information Criterion (AIC) value averages 13.0294%.

Videos are considered the new era communication language between internet users due to the explosion of smart-phones usage and increase in internet bandwidth and storage space. This has fueled the need to develop robust video analysis techniques. Specifically, video classification presents a unique task for field researchers, as it has numerous critical applications, such as video indexing, searching, annotation and surveillance. Videos inherently embody static and dynamic information that is encoded in frames. The task is further prioritized due to the gigantic amounts of available videos in the digital world, which requires a robust way to organize these videos. Throughout literature, researchers have generally adopted three main techniques to classify videos, i.e., direct features matching, machine learning-based methods, and deep learning-based methods. Each of these methods is suitable for a specific application type. This paper is designed to assess which of the three common working approaches are better for video classification. Furthermore, the paper aims to examine whether and how these methods affect/improve video classification performance and key factors to constructing a robust video classification system. This novel research paper covers an important research gap by introducing a rigorous comparative analysis of the three methods highlighting their advantages and disadvantages and guiding field researchers. A comprehensive analysis brings the paper findings together using a benchmark group of challenging large-scale video datasets (~29k videos). This would provide field researchers with the necessary information to choose the best method for their video classification research work.

Three-dimensional (3D) printing is a recent technology, which gives the possibility to manufacture personalised dosage forms and it has a broad range of applications. One of the most developed, it is the manufacture of oral solid dosage and the four 3DP techniques which have been more used for their manufacture are FDM, inkjet 3DP, SLA and SLS. This systematic review is carried out to statistically analyze the current 3DP techniques employed in manufacturing oral solid formulations and assess the recent trends of this new technology. The work has been organised into four steps, (1) screening of the articles, definition of the inclusion and exclusion criteria and classification of the articles in the two main groups (included/excluded); (2) quantification and characterisation of the included articles; (3) evaluation of the validity of data and data extraction process; (4) data analysis, discussion, and conclusion to define which technique offers the best properties to be applied in the manufacture of oral solid formulations. It has been observed that with SLS 3DP technique, all the characterisation tests required by the BP (drug content, drug dissolution profile, hardness, friability, disintegration time and uniformity of weight) have been performed in the majority of articles, except for the friability test. However, it is not possible to define which of the four 3DP techniques is the most suitable for the manufacture of oral solid formulations, because the selection is affected by different parameters, such as the type of formulation, the physical-mechanical properties to achieve. Moreover, each technique has its specific advantages and disadvantages, such as for FDM the biggest challenge is the degradation of the drug, due to high printing temperature process or for SLA is the toxicity of the carcinogenic risk of the photopolymerising material.

successful design of folding bicycle should take into account the function, material properties, and fabrication process. There are some other factors that should be considered in anticipating the behavior of materials for folding bicycle. In order to understand the relationship between material properties and design of a folding bicycle and also for the future direction in new materials with new design, a comprehensive study on the design under different conditions are essential. Therefore, a systematic study on the relationship between material properties and design for folding bicycle has been performed. The advantages and disadvantages matrix between conventional bicycle and folding bicycle is presented for better understanding of the materials properties and design. It was found that the materials properties of the folding bicycle frame such as fatigue and tensile strength are the important properties for the better performance of the frame. The relationship between materials properties and design is not straight forward because the behavior of the material in the finished product could be different from that of the raw material. The swing hinge technique could be a better technique in the design for the folding bicycle frame.

The aim of the work was to present the issue of eco-efficiency, based on the PN-EN ISO 14045:2012 standard in relation to the production of fatty acid methyl esters (FAME). The ecoefficiency analysis takes into account economic and environmental aspects in the improvement of products and processes / technologies. Eco-efficiency considers the product and technology throughout the life cycle, from the construction phase, through use to decommissioning. The impact on the natural environment is assessed on the basis of: consumption of energy, materials, dust and gas emissions, waste and sewage. Total costs include: production costs, raw material costs, costs during the use phase including maintenance, repair and operating costs, product disposal or recycling. The eco-efficiency analysis is helpful in making decisions regarding the selection of a new product or designing a new technology, and enables the selection of the variant that is the most economical and has the least possible impact on the natural environment. These issues are particularly important in the case of biofuels. The rapid growth of their production and the European Union’s policy, which aims to increase the share of energy from renewable sources, cause concerns of many experts regarding the threats related to the production of biofuels, both for the environment and food security. In particular, efforts are made to minimize the amount of waste and residues by implementing the idea of a circular economy. This approach promotes the development of new technologies that are more environmentally friendly. Due to the regulations set out in the RED and RED II Directives, there is a chance that the biofuels will have a less negative impact on the environment. This results from the obligation to certify compliance with the sustainability criteria, which is carried out by voluntary systems recognized by the European Commission, such as the KZR INiG System.
