George de Bothezat and his contribution into the world aviation and astronautics

The article dedicated the life and scientific way of George de Bothezat, the first Doctor of Sciences in the field of aviation. Together with Nikolay Zhukovsky, Igor Sikorsky, Stephen Timoshenko, Alexander Fan-der-Flit, and Alexey Lebedev, he was one of the organizers of the Air Fleet of the Russian Empire. He is the author of various inventions: gyroscopic sight and other types of aviation equipment. We analyze works by G. Bothezat on the impulse theory of propellers. In particular, the scientist derived formulas for ensuring the flight stability of airplanes and helicopters. He developed training ballistic tables, which allowed making corrections for the speed of the flight and the direction of the wind. We briefly describe a biography of G. Bothezat, focusing on the student period of his life in Kharkiv, Ukraine, and the reasons for G. Bothezat’s departure to the United States in 1918. It is stated that it was there that his talent as a designer and creator of helicopters of the original system was disclosed in the best way. In 1922, George Bothezat obtained the financial support of the American government to build a workable helicopter model without prototypes and experiments, only based on the results of calculations. The reasons why G.Bothezat did not manage to achieve the launch of the serial production of helicopters are analyzed. We also mention the activities of the company founded by G.Bothezat, which was engaged in the production of fans of a new type for the US Navy. The Bothezat system fans were installed at the Rockefeller Center in New York as well as in American tanks. It is emphasized that I. Sikorsky also used the works by G.Bothezat in his research. It is stated that the flight trajectory calculated by G.Bothezat in air and airless space was used in the development of the American program of a manned landing on the Moon using the “Apollo” system.

Phenomenon of fandom consumption in k-pop commodity through the army community

The appearance of ARMY as a loyal fans is a response to what BTS has to offer as a K-Pop idols. Aside being a fan, their consumption behavior is inevitable. Along with the development of media technology and as a result of pop culture commodities, fans create its own meaning and culture as an active actor of consumption. This research provides an overview of the way consumption culture is formed in ARMY fandom and how it affects most significant aspects in their life. The researcher also wants to examine related to the concept of free fan labor that fans holds such an important role at maintaining the fan production culture in the web and benefit the K-Pop industry to broaden their market globally. This research uses a qualitative method. Then the researcher collects data by interviewing six informants who have consume BTS merchandise continuously with purposive sampling technique. The result of this research showed that fans consistently interpret the goods they consumed, the value they generate from their sense of closeness to BTS members. This research also demonstrated regarding fans becoming “free” fan labor with their own eagerness, along with the fan production culture results to the personalize customization into their own interest as an active and loyal costumer, with the exchange of pleasure they got from actively interact and exchanging feedback with another fans in the cyberspace.

Old Plays, New Narratives

When a theatrical performance is digitally broadcast live to cinemas, the limitations of temporal and spatial specificity are removed and the theatrical experience is simultaneously opened up to a wider audience and inherently altered. One such production, Coriolanus (Donmar Warehouse, 2013-14), starring an actor with a particularly enthusiastic online fan community, was broadcast to cinemas by National Theatre Live, where fans recorded it on digital devices, extracted clips and produced animated gifs, which they captioned to reinterpret the play, sharing them online, removed from their original context. The transformation of theatre texts to cinemas to social media platforms raises exciting questions related to how fans interact with culture both as consumers and as producers of new media texts. How do the different transformations (technical and actively fan-produced) affect both the narrative and the cultural experience? How do new texts function as surrogates for, and extensions of, the ‘official' narrative, as well as new interactive narratives in their own right? This paper addresses these questions in the context of a specific theatrical event as it crossed the boundary from a live, co-located experience first into cinema, and then into interactive hypertexts and memes. Drawing on theories of fandom and participatory culture, as well as post-Web 2.0 analyses of Internet behaviours, the paper examines fan production of new media texts and how they both transmit and transform the source narrative via interpretation, re-interpretation, and misinterpretation.

Modelling and intelligent prediction of sound quality for high-voltage fans on fuel cell vehicles

Since fuel cell vehicles have much higher heat dissipation requirements, 350-V high-voltage fans are adopted instead of traditional 12-V cooling fans, generating more aerodynamic noise. The installed fans are required to possess not only low sound pressure level but also good psychoacoustic performance. This paper is aimed at solving the complex correlation between subjective sound quality evaluation results and objective psychoacoustics parameters and establishing a sound quality prediction model for high-voltage fans. The noise signals of two high-voltage fans operating on a fuel cell vehicle under different running conditions are collected by an artificial head and preprocessed to acquire seven objective parameters. Then the subjective evaluation experiment on the annoyance of the noise samples is carried out based on pair-wise comparison method. A sample group of 23 adults is selected and a graphical user interface is programmed for test guiding. The subjective annoyance scores of the noise signals are obtained after data processing and effectiveness verification. By analyzing the tested results, the correlations between the subjective score and each of the single psychoacoustic parameters are summarized. Two sound quality prediction models are established by multiple linear regression and backpropagation neural network respectively, and the training results of the two methods are verified and compared, proving the reliability of neural network training results. With the established models, the sound quality of the high-voltage fans can be estimated effectively without complex subjective tests, contributing to improving the acoustic performance of fan products.

Periphery fandom: Contrasting fans’ productive experiences across the globe

The article introduces the concept of periphery fandom, a concept that is new in the debate on consumer culture, to interrogate global fan community productive experiences from various geographical locations. Periphery fandom is defined as a sub-ordinated fan community experience, where members are deprived of access to their objects of fandom. Periphery fandom also refers to a fan productive experience that is detrimental to the fan community ethos. This notion of periphery fandom is underpinned by insights from fandom studies, brand community scholarship, and core and periphery theories. Using adult fans of LEGO as an example, this article demonstrates the character of periphery fandom. By contrasting the data gathered from 2014 to 2019 during UK, Japan, USA, and Brazil LEGO fan events, this study reveals how fans’ divergent productive practices and community experiences are influenced by their geographical location. Moreover, the fan productive experiences from the periphery further hinder their creative expressions and visibility, creating a more fragmented global brand fandom landscape. This study overall advances a contribution to the fandom debates by contrasting fan production and fan brand experiences.

Environmental impacts of implementing basket fans for heat abatement in dairy farms

Health and welfare impairments in dairy cows have been described to increase environmental impacts of milk production due to their negative effect on cow productivity. One of the welfare problems is heat stress, which is gaining importance even in temperate regions. While improving animal welfare may reduce emissions, the mitigation potential depends on the environmental costs associated with specific intervention measures. Taking abatement of heat stress as an example, the aim of the present study was to estimate the effect of implementing mechanical ventilation devices on the contribution potential of milk production to global warming (GWP), terrestrial acidification (TAP) and freshwater eutrophication (FEP). Environmental impacts of two modelled production systems located in alpine and lowland production areas of Austria were estimated before and after the implementation of basket fans, using life cycle assessment. Region-specific climate data were retrieved to determine the number of days with heat stress and to evaluate heat stress-induced productivity shortfalls in the baseline scenario (Sbasic). In the intervention scenario with increased ventilation (Svent), this decline was assumed to be eliminated due to the convective cooling effect of fans. For Sbasic, mean GWP, TAP and FEP impacts were estimated at 1.2 ± 0.09 kg CO2-, 21.1 ± 1.44 g SO2- and 0.1 ± 0.04 g P-equivalents per kg milk, respectively. Independent from the production system, in Svent, implementation of fans did not result in significant environmental impact changes, except for FEP of the alpine system (+5.9%). The latter reflects the comparatively high environmental costs of additional cooling regarding FEP (+2.3%) in contrast to GWP (+0.4%) and TAP (+0.1%). In conclusion, the estimated overall effects of mechanical ventilation on GWP, TAP and FEP of milk production were minor and the model calculations point to the potential of heat stress abatement to at least outweigh the environmental costs associated with fan production and operation. To confirm this trend, further assessments are needed, which should be based on primary data regarding the effectiveness of fan cooling to improve cow productivity, and on emission calculation schemes that are sensitive to environmental factors such as wind speed and temperature.

Validation of the Lattice Boltzmann Method for Simulation of Aerodynamics and Aeroacoustics in a Centrifugal Fan

Due to the fact that legal and market requirements are becoming stricter, fan noise reduction, in addition to energy efficiency, represent a challenge for fan product designers. Most experimental studies are associated with trial-and-error approaches. Therefore, numerical methods are mostly preferable. However, the quantitative prediction of the noise emitted by radial fans via numerical simulations remains challenging. The Lattice Boltzmann method (LBM) is a relatively new approach that promises a direct calculation of the aerodynamics coupled with the aeroacoustics. This article presents an LBM simulation of a centrifugal fan using the commercial Lattice Boltzmann Code SIMULIA PowerFLOW of Dassault Systèmes. The simulation model includes both the fan impeller and the spiral housing. In accordance with the experimental setup, the fan was mounted in a test bench to analyze four different operating points. The results of the LBM simulation were validated by experimental measurements. Flow information in terms of pressure rise and efficiency of the centrifugal fan as a function of the flow rate are in a good agreement. Considering the acoustic spectra and the blade passing frequency, the simulation was able to precisely predict the noise of the centrifugal fan. The simulation results are also used to visualize the flow and acoustic field inside of the fan to detect noise-generating flow features. By evaluating the filtered pressure fluctuation in the fluid volume and on the wall, four main noise sources of the centrifugal fan can be identified.

Il fumetto digitale tra sperimentazione e partecipazione : il caso Homestuck = Digital comics halfway between experimentation and participation : the example of Homestuck

Digital comics that try to maximize the affordances of their medium seem to be condemned to in-betweenness: their strength (leveraging on unusual narrative potentials) often becomes their limit, and authors are hardly able to free themselves from the role of niche experimenters and open up to audience participation. A significant exception, however, is Homestuck, a gigantic webcomic by Andrew Hussie. Strongly connected to videogame culture and the very nature of the internet, Homestuck features animations, sounds, embedded flash games, and so on. The webcomic resulted in various transmedial branches (a videogame spin-off and several friendsims, a multi-volume soundtrack, a book epilogue) and an ongoing intermedial adaptation in book format. It has equally managed, over the years, to consolidate an extremely lively community active both in its interactions with the author (with a constant exchange of ideas and an endless readiness to subsidize his projects), in its interpretation of the canon production, and in providing an amazing extent of fan production. This contribution aims to analyze Homestuck as a possible mediation between the two inclinations (experimental and participated) of digital comics.

Application of Gray Relational Analysis and Computational Fluid Dynamics to the Statistical Techniques of Product Designs

During the development of fan products, designers often encounter gray areas when creating new designs. Without clear design goals, development efficiency is usually reduced, and fans are the best solution for studying symmetry or asymmetry. Therefore, fan designers need to figure out an optimization approach that can simplify the fan development process and reduce associated costs. This study provides a new statistical approach using gray relational analysis (GRA) to analyze and optimize the parameters of a particular fan design. During the research, it was found that the single fan uses an asymmetry concept with a single blade as the design, while the operation of double fans is a symmetry concept. The results indicated that the proposed mechanical operations could enhance the variety of product designs and reduce costs. Moreover, this approach can relieve designers from unnecessary effort during the development process and also effectively reduce the product development time.

Copyright Disclaimers in Fan Media: Cultural Practice and Legal Relevance

Disclaimers are used in diverse contexts of popular culture and for a wide range of purposes. With digitisation in general and the rise of participatory fan culture in particular, copyright disclaimers have become a familiar and common means of communication. In this paper, we define them as paratextual media of cooperation. The practice of disclaiming seeks to establish mutually accepted conditions for publishing works that owe their existence to different stakeholders. Embedded in empirical legal studies, our paper is based on our own empirical research and a thorough legal assessment of findings through the lens of German copyright law. Our qualitative study on disclaimers in fan fiction highlights a distinction between “vertical” forms of disclaimer usage addressing the copyright holders and creators of a reference work, and “horizontal” forms directed to either the potential readers or other fan fiction authors. While in general fan-made disclaimers are of no significant relevance from the perspective of German law, a closer look reveals a stronger impact in cases where creators and copyright holders publicly articulate attitudes towards fan production and/or set specific conditions. Beyond the law, as a practice, disclaiming is part of the nexus of informal rules and community ethics which guide users’ actions.

Fans Make Art: Authoring and Creativity in the Production of Fanvideos

The research aims to analyze how Brazilian produce fanvideos based on successful pop culture franchises. For such, assumes that fans are prosumers of pop culture in a context of participatory culture and that fanvideos are user-generated content propitiated by Web 2.0 technologies. A total of 257 fanvideos posted between April 2006 and February 2018 were analyzed through Interpretive Content Analysis. Five types of fanmade productions were identified: fandub, fanart, fan animation, fan music and fanfiction. Such production demonstrates that fanvideos reveal the fans' desire to make art, what occurs both as a way for the fans relate to the franchises they admire, as well as to express themselves based on them. By doing this, they wide the scope and the narrative possibilities of the franchises through intra- and inter-textualities in relation to the universe of pop culture and their own daily experiences. The research presents an original approach to user-generated content in association to fan production and the notion of prosumption. As limitation, the study is delimited to the Brazilian production of fanvideos. Future similar research could be carried out in other countries, as well as regarding other fan productions.

Some Bounds of Eigenvalues for Hadamard Product and Fan Product of Tensors

In this paper, some new upper bounds on the spectral radius of Hadamard product of nonnegative tensors are given. To show their sharpness, the comparisons among these bounds, including the existing one by Sun et al. (Linear Multilinear Algebra 66:1199–1214, 2018), are performed. We also present some lower bounds on the minimum eigenvalue of Fan product of irreducible strong $${{\mathcal {M}}}$$ -tensors and their sharpness under different conditions are investigated. Some numerical examples are provided to illustrate our theoretical results.

Produções e produtos culturais na sala-de-aula: uma análise crítico-dialógica do fandom de Harry Potter e da franquia Meu Malvado Favorito

This article aims to think of cultural productions, transformed into consumer products, in the classroom, as dialogic strategies of critical formation. The proposal is to reflect on the presence of these productions and products from two iconic works of the cultural industry for their virality: Harry Potter and Despicable Me - the world's largest fandom community and the success of minions, specifically in Brazil. The theoretical foundation is based on Bakhtinian studies in dialogue with critical theory. Harry Potter will be thought through the production of fans and Despicable Me in the fields from the image of the minions. It is intended to think about the relationship between school and society, as well as about the constitution of school life as a citizen formation, and this is its relevance.

‘I’m never gonna stop watching it’: The paradox of parasocial break-ups in a post-object era

In this article, we propose an understanding of parasocial relationships, in which fans build an affective relationship with characters and television programmes, as fandom’s emotional interior. Rather than being structured by fan productivity and community, parasocial relationships exist in a private, intimate space as fans develop deep emotional bonds with characters. When a series concludes, fans must therefore reconcile the dissolution of these relationships in a personal way, a process called the parasocial break-up. However, the current media landscape fosters the sense that the fan object is never truly ‘over’, which tempers the negative emotions of the parasocial break-up. Interviews with fans of The Office revealed that this process is paradoxical, as fans assert both the devastation of loss and the agency of denying that loss.

Manufacturing Defect Detection in Ceiling Fans using Image processing

During manufacturing process of ceiling fans there may be possibility that any step of manufacturing process can be skipped or improper completion due to malfunctioning of the system. In manufacturing process of fans, the outer plate, stator, rotor, axle and other parts are manufactured and assembled. If the winding machine is not working properly and improper windings is done and no-one can acknowledge that winding machine is not working properly then the whole batch should be designed with defect and this will surely create negative impact on the production process of the industry. So this proposed work will overcome this problem. This paper guides to detect whether the windings are proper or not and detection is carried out by taking picture of armature-windings. If there is any problem in the windings then our system will generate an alert so that other armatures can be protected from failures. Manual results are not so accurate all the time but in manufacturing process we need high accuracy. For this skilled labor is required and for skilled labor we have to pay more, this automated system reduce the need of skilled labor. If fan manufacturing industries use this image processing system then this will be very helpful in increasing production of fans within the completion time with more accuracy

Brualdi-type inequalities on the minimum eigenvalue for the Fan product of <i>M</i>-tensors

In this paper, we focus on some inequalities for the Fan product of $ M $-tensors. Based on Brualdi-type eigenvalue inclusion sets of $ M $-tensors and similarity transformation methods, we establish Brualdi-type inequalities on the minimum eigenvalue for the Fan product of two $ M $-tensors. Furthermore, we discuss the advantages of different Brualdi-type inequalities. Numerical examples verify the validity of the conclusions.
