Process Optimisation for Robotic Manufacturing System to Implement Industry 4.0
No full textTo ensure the scheduling of processes, improve accuracy, and minimize quality impairment due to vibration caused by operational difficulties. Low stiffness and inadequate accuracy are generally considered as the two primary challenges confronting current automated manufacturing technologies. When used in production, cognitive appliances flexible arms suffer dynamical accuracy considering they are extremely versatile, agile, and easily maneuverable. The machine's muscles shaking and clattering will result in poor production performance. The key problems with modern robotic machining systems are often described as low rigidity and poor accuracy. Robotic machining with process optimisation and manual programming takes responsibility for countless operational elements, allowing businesses to get a deeper knowledge of their operations. These include mechanical investigation, method improvement, and computerized supervision. Digital simulation of processes using AI and ML boosts implementation rates of effectiveness. This enables businesses to reduce process restructuring while continually refining production processes and modeling machining capabilities to increase reliability and precision
Digital twin of robotic manufacturing system for Industry 4.0
No full textThe emergence of technology known as Industry 4.0 has changed traditional production methods. Regardless of the presence of advancements such as the Internet of Things, CPS, machine learning, mutually beneficial and self-contained robots in manufacturing settings, and considering the fact that the primary goal of Industry 4.0 is to execute more interconnected, adaptable, and more sophisticated manufacturing circumstances, certain components still need better integration and implementation. The approach recommended is applicable to comparable Digital Twin technologies which get information from their real-life counterparts via sensors. Systematically incorporating additional detection devices into the workflow, the technique may be extended to various systems. Different data-driven strategies can also be applied in the assessment of the errors and misalignment anticipation procedure. Low stiffness and poor precision are typically cited as important problems for advanced robotic machining systems. Robot adjustable ammunition is exceedingly nimble and versatile, with good portability, resulting in an impairment of kinetic precision while utilized for machining. The present study focuses mostly on adjustment utilizing extra identifying and control, asynchronous information technology, and so forth. The possibilities are often limited to a robot. A digital twin of the robotic production system will be suggested in this study
High Gain Dipole Tape Antenna for IoT PocketQube/CubeSat, Satellite Applications
Full text linkThis paper presents the design and optimization of a high-gain foldable Dipole Tape Antenna tailored for IoT nanosatellite communication platforms. The increasing demand for compact, efficient, and reliable antennas in space-based applications, particularly for CubeSats and PocketQubes, necessitates innovative solutions. The proposed antenna operates at the 433 MHz RF band, addressing critical size and deployment constraints through a foldable design, enabling compact storage and expansion post-launch. Advanced simulation techniques have been employed to optimize gain (5.7 dBi), bandwidth (11.55%), and radiation efficiency, ensuring robust performance. Comparative analysis with existing designs demonstrates superior characteristics in terms of miniaturization, impedance matching, and radiation pattern stability. This research contributes to advancing space-based IoT connectivity, providing an effective solution for nanosatellite communication systems
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
