Effects of aromatic on soot characteristics of aviation fuel surrogates in diffusion flames
Authors: Hong Thong Duc , Fujita Osamu
Published: November 2018

Co-annular smoke-free laminar diffusion wick-fed flames of dodecane and its blended with various amounts of propylbenzene of 10, 20, 25 vol.% have been used to study soot formation characteristics. Dodecane and propylbenzene are selected as the surrogates for paraffin class and aromatic class of aviation fuel. A light extinction method is adopted to determine the total soot volume (TSV) as a function of flame height (Hf) and fuel mass consumption rate (FMCR). An empirical model has been built to predict soot formation of dodecane and propylbenzene (Do/PB) mixtures as the function of two variables of FMCR and concentration of propylbenzenet (%PB). TSVs of Do/PB mixtures increase with increasing Hf, FMCR and %PB. The effect of Hf, FMCR and %PB on soot formation are respectively expressed as the quadratic, power law and linear functions. The result of current work creates a database for optimizing the trade-off impacts of aromatic in aviation fuel. This information is of high importance when blending aromatic to bioparaffins, which is produced from triglycerides and fatty acids in the vegetable by hydrotreating process, for using as a fuel in aircraft engines.

In a diversity of rescue scenarios, operations to response to climate change, flood and storm control, search and rescue should be quick and capable over complicated environment. The ability of hovercrafts is to hover above land, and water, even during flood and landslide conditions, is a lifesaving asset to both victims and rescuers from mentionned rescue zones. Due to their unique capability to safely access any areas that no other rescue vehicle can reach, hovercraft are used in a diversity of rescue scenarios with performances appropriated with required tasks. The search and rescue activities in recent floods and storms show that to build domestic hovercrafts is great significant. This paper aims at general issues about the hovercraft designs to meet the domestic demands.

The processes of heat-humidity treatment (cooling with dehumidification) of air in a two-stage air cooling system at the inlet of a gas turbine unit applying a combined type heat-energized refrigeration mechanism, which consists of an absorption lithium-bromide high-temperature refrigeration mechanism to approximately 15 °C and a refrigerant ejector low-temperature refrigeration mechanism to 10 °С and below, which transform the heat of exhaust gases from gas turbine unit to the cold with the production of condensate in air cooling system as a by-product of air cooling has been analyzed. The analysis was carried out for the climatic conditions of the south of Ukraine. The heat removal from the condensers and the absorber of the heat-energized refrigeration mechanism are carried out with open wet cooling towers. Based on the distribution of the heat load on the steps of the two-stage air cooling system and the heat coefficients of the heat-energized refrigeration mechanisms, the project load on the cooling towers was determined and their number was selected. Based on the results of modeling of the operation of the air cooling system at the inlet of the gas turbine unit, were obtained data from the current and total amount of condensate that falls in the air cooling system during the condensation of water vapor, which is always contained in moist air, as well as the amount of water needed to feed an open cooling tower. In this case, only water losses due to mechanical removal (without taking into account its evaporation in cooling towers) were considered, which poses the problem of separation of droplet moisture from the aerosol mixture. As a result of comparing the amount of water needed to feed the cooling towers, on the one hand, and the amount of condensate obtained in the process of air cooling at the inlet of the gas turbine unit, on the other hand, was demonstrated that it is possible to partially satisfy the necessary water needs for cooling towers. A scheme of two-stage air cooling system at the inlet of a gas turbine unit with absorption lithium-bromide and refrigerant ejector refrigeration mechanism and wet cooling towers is proposed, to discharge heat from heat-energized refrigeration mechanisms, to produce condensate as a by-product of air cooling, and apply it to feed cooling towers

The subjects of the study are methods and devices of generating gas mixtures with a specified accuracy and a high repeatability of the component dosing. The purpose of the article is to develop an algorithm for controlling the fuel mixture generation system for precision thermal pulse treatment. In that behalf, the research tasks are the improvement of the critical hole method with reference to the thermal pulse treatment and the methodology development of parameters assigning for mixture generation system ensuring high accuracy and repeatability of the dosing of its components and heat flows in thermal pulse treatment. The following results are obtained. The method of dynamic mixture formation based on the method of critical holes is proposed. Its special advantage is that during the filling of the chamber, the components of the fuel mixture expire from the pre-filled intermediate pressure vessels with the controlled volume without the application of any regulating devices. The technique for choosing the diameters of critical apertures, the volumes of intermediate tanks and the initial pressure in them, providing accuracy of components dosing at the level 0,01 % is developed. The technical solutions that allow to stabilize the value of heat flow during thermal pulse treatment, considering the operation dynamics of the valves in the mixture generation system and the variable temperature of the chamber walls are proposed. The following conclusions are formulated. The method of generating fuel mixtures for precision thermal pulse treatment based on the method of critical holes is proposed. It is characterized by the fact that during the mixture formation, the free exhaust of gases from pre-filled intermediate tanks is applied. The developed procedure for calculating the parameters of the mixture generator on the basis of the proposed method makes it possible to determine the ratio of the areas of the critical holes, the volumes of the tanks, the initial pressure in them and the time of filling the chamber according to the given composition and pressure of the mixture at normal temperature. The algorithm for controlling the generation of a mixture for precision thermal pulse processing is developed. The necessity of controlling the opening and closing speed of the gas supply valves is shown taking into account the required ratio of the areas of critical holes. To ensure a stable value of heat fluxes during cyclic thermal pulse treatment, it is shown that it is necessary to simultaneously monitor the charge mass and the pressure in the chamber when the fuel mixture is supplied, followed by correcting the treatment time according to the calculated initial temperature of the fuel mixture

The first stage of providing selectivity of devices for analyzing the spectrum of polyharmonic signals observed against the background of parametrically uncertain Gaussian noise is considered: detection, measurement of the number of discrete components of the spectrum of the real process. Model representations and requirements formulated in the set part of the problem to be solved correspond to the concepts and problems of the current state of diagnostic practice, which is associated with the study of the characteristics of vibration processes of various units. In particular, information on the number and levels of harmonics in operating conditions is a sign of defects in the work and the degree of their development. In the framework of the statistical theory of many alternative solutions using the criterion of the likelihood ratio proposed method for solving the problem of detection and estimating the number of harmonic components of the spectrum of a time-limited real process. On the basis of the developed methodology, the rule of making decisions with a given degree of reliability in favor of any of the hypotheses put forward about the number of harmonic components of the spectrum of the real signal observed against the background of parametrically uncertain Gaussian noise is synthesized. It is proved that in the considered model representations in solving this type of statistical problems it is advisable to focus on the analysis in the interference subspace of the correlation matrix of observations. A distinctive feature of the synthesized decision-making rule: meets the methodology of maximum likelihood, critical statistics is formed on the basis of the characteristic value of the correlation matrix of observation, standard computational operations are applied for implementation. The distribution density of critical statistics is tabulated. This makes it possible to "a priori" to set the required value of the significance level. Certification of the synthesized test-decision-making rules in favor of the proposed hypothesis about the prevailing number of harmonic components in the spectrum of the process is carried out at the level of digital statistical modeling. As the initial data were given: q – the value of the significance level (0.05; 01); P – noise power; the number of harmonic components N=2. In experimental studies, the amplitude of the second harmonic varied from 0 to the amplitude of the first harmonic. The results of the modeling analysis of the relationship between the number of correct decisions (made hypotheses) from changes power the second harmonic at a given ratio of signal/noise. The obtained performance characteristics of the algorithm confirmed the theoretical conclusions of the research.

Considering the long negative influence of the human factor on flight safety, ICAO has been orienting the leadership and specialists of state aviation administrations and airlines to the proactive prevention of this phenomenon, demanding flight safety effective management "by indicators". These indicators in terms of professional activity of air traffic controllers (ATC) are defined: the relation to the risk (the main decision-makers and controversial estimates of SOP's violations), levels of claims, preferences systems, and dangerous behavior strategies, operational thinking and decision making that, in contrast to formally computational methods reflect the implementation of the methodology of psychological decision theory and cognitive psychology. The main decision-making dominants (inclination, disinclination, and indifference to risk) are revealed in the process of proactive decision by the controllers of closed decision-making tasks by constructing, with the help of special artificial lotteries and a limited number of points, the utility functions of the continuity of aircraft separation standards in the horizontal plane. For the separation standard S = 20 km, the proportion of students-controllers (n = 128 persons) of inclined (INC), indifferent (IND) and disinclined to risk (D) was detected: INC:IND: D ↔ 5: 18: 105 ↔ 3.9%: 14.1%: 82.0% ↔ 1: 3.6: 21, which indicates their desire to avoid failures in their professional activities. Therefore, the quantitative indicator of demonstrated risk aversion increases with the complication of the separation standard (reducing the distance between aircraft). For the separation level S = 10 km it is established: INC:IND: D ↔ 5: 8: 115 ↔ 3.9%: 6.3%: 89.8% ↔1: 3.6: 21. In professional controllers (n = 70 persons), for the separation standard S = 20 km, the ratio of persons with different dominance of decision-making was found: IND: INC ↔ 9: 25: 36 ↔ 12.9%: 35.7%: 51.4 % ↔1: 2.8 : 4, which indicates an overwhelming demonstration of their motivation to achieve success in the same working conditions. The motivation increases with the complexity of the separation standard: for S = 10 km it is established: D: IND: INC ↔ 4: 18: 48 ↔ 5.7%: 25.7%: 68.6% ↔ 1: 4.5: 12. It is recommended to apply the obtained results during the organization of the person-oriented training of young dispatchers aiming at developing stable skills for making rational risk decisions.

Depression is an unfavorable condition for the elderly. When depression goes untreated, elderly can isolate themselves even allowed to end his life. Spiritual Emotional Freedom Technique (SEFT) and Keroncong music allegedly can be used as complementary therapy for elderly depression. This study aimed to determine the difference effect of Spiritual Emotional Freedom Technique (SEFT) and Keroncong music on elderly depression at Jombang geriatric service unit in Pare Kediri. The method used was a quasi-experimental, with a pretest and posttest design. In this study, respondents were grouped into two groups, SEFT intervention group (n=10) and Keroncong music Intervention  group (10). In both groups was given four  therapy sessions, within four weeks, each session is given therapy for 30 minutes.. In this study it was found that the decrease of score depression between pretest and posttest at SEFT therapy (p = 0,008) and keroncong music therapy (p = 0,01). By unpaired t test, posttest obtained, the p value (p=0,760) >0.05 so that there is no significant difference between the posttest score in the SEFT Therapy group and the keroncong music therapy  group. It can be concluded that SEFT and keroncong music  reduce depression in elderly, but no more effective between SEFT and keroncong music reduce depression in elderly.

The shifting representation of Japan in Belgian comics, in fifteen years after WWII (1945-1960)
Authors: Lefèvre Pascal
Published: November 2018

This paper focuses on how Japan was represented in the most popular Belgian comics at a particular period in time, right after the Second World War and just before the image of Japan as an economic superpower (that exported many commodities to Europe or the USA) became widespread from the 1960s on.
Within the field of European comics, Belgian comics played a crucial role in the decades after the war with major artists such as Hergé, Franquin, Jacobs, Vandersteen and many others. Moreover, the Belgian comics industry attracted many artists from other countries and exported her products to various countries (especially France). The comics published in dailies, journals and albums formed at that time an important means of entertainment for the youngsters (television started only in the 1950s in Belgium). Furthermore, the Belgian comics culture is interesting since it involves two different traditions: a French language one and a Dutch language one.
In various stories, published between 1945 and 1960, we find representations of Japan. On the whole, two basic approaches of the Japanese Otherness stand out:

the “Yellow Peril”, strongly referring to the last World War (for instance Jacobs Blake et Mortimer, Le Secret de l’espadon, Hubinon & Troisfontaines, Charlier Buck Danny, Les Japs attaquent). Usually these comics were drawn in a more realistic style.
the “touristic ancient or exotic Japan” without any reference to WWII (for instance Vandersteen Suske en Wiske, De Stemmenrover, Will & Rosy Tif et Tondu, Le Fantôme du samouraï). Usually comics of this approach combine adventure and humour.

The first kind of comics is typically for the comics produced in the first years after war, while the second kind is rather typical for the late 1950s. So, even in this brief period of 15 years already an important shift of the image of Japan is noticeable, from a belligerent enemy to an exotic and touristically interesting culture. The paper will offer a more detailed analysis of some examples and formulates some possible explanations for this shift.

Mutual Images, the journal, is the intellectual offspring of a small cultural and academic society officially registered in France in 2014. Two young French scholars, Aurore Montoya and Maxime Danesin (who are now the President and Vice-President of Mutual Images), after a very fruitful academic year 2010-11 spent as visiting students at K?nan University (K?be, Japan), decided to take a bold and stimulating intellectual initiative. They therefore embarked in the design and organisation of an interdisciplinary workshop for students and young academics, dedicated to the theme of “mutual images” between Japan and Europe in the fields of arts, social sciences, anthropology, cultural studies, visual media, and literature. As the venue of the workshop’s first edition in 2013, they chose K?nan University itself, thanks to the kind and enthusiastic cooperation of their former professors there.

Twice hypervisual: Expanding on North American and Western European critiques of the Visual via Azuma Hiroki’s theory of postmodern hypervisuality
Authors: O'Brien Dylan Hallingstad
Published: November 2018

In this article, I contend that attending to the intersections of embodiment and cultural experience is especially fruitful in considering Azuma Hiroki’s postulation of hypervisuality. Putting hypervisuality into dialogue with North American and Western European work on the visual, and senses more broadly, I argue, offers a chance to see how the culturally and historically contextual privileging of sight and processes of representation coincide to help produce a modality of narrative engagement that conflates an individual’s singular reading with the potentiality for such a reading’s universal experience.While Azuma Hiroki’s D?butsuka suru posutomodan: otaku kara mita nihon shakai (2001) has often been considered in Anglophone reception as a work examining a specific Japanese subculture, I turn in this article to his theory of the ‘hypervisual,’ and place it into relation with work on the cultural contours of the visual. Herein, I place such an idea of hypervisuality in relation work that is critical of North American and Western European cultural elevation of the visual as the most valued sense and preeminent way of knowing. Together, I hold, these bodies of work push us further towards an understanding of processes of interpretation and narrative engagement in the present.

Interrogating self and other: Mutuality in the visual art of prewar Japan
Authors: Hartley Barbara
Published: November 2018

In pre-war Japan, the visual artist often played a complicit role in the circulation of dominant imperialist and militarist discourses. Yokoyama Taikan (1868-1958) and Fujita Tsuguharu (1886-1968), for example, produced images extolling Yamato military might. This ‘might’ is evident both in the metonym of Yokoyama’s soaring Fuji-san images, often with rising sun ascendant, and in the more realist representation of Fujita’s Soviet tanks under assault at Nomonhan by ‘triumphant’ Japanese troops. Some pre-war and war-time visual art, however, resists being viewed as a conventional ‘hagiography of Japan.’ This, paradoxically, is especially the case in images depicting sites occupied by Japanese military and capital interests. These images, in fact, often reveal the highly tenuous nature of the discursively constructed border that divided the naichi Japanese self and the gaichi colonised other. Rather they convey a sense of mutual subjectivity in which the agency of the ‘other-ed’ subject insists on asserting itself. This presentation will provide a detailed examination of three pre-1945 works of visual art and consider how these uncover the mutuality inherent in old notions of self and other in pre-war Japan. The first is a 1937 image entitled ‘K?nan no haru’ (Jiangnan Spring) by Arishima Ikuma (1882-1974), a scene from the rural environs of Shanghai featuring two young women in Chinese dress and an Imperial Army soldier mounted on a white horse. The second is a 1942 image entitled ‘Shimai heizaz?’ (Sisters Sitting Side-by-Side), painted in Beijing by Umehara Ry?zabur? (1888-1986). The third is a 1944 work by Tsuruta Gor? (1890-1969) entitled ‘Shiganhei no wakare o tsugeru Taiwan no hitobito’ (People of Taiwan Farewelling the Volunteer Troops) which depicts indigenous people of Taiwan saluting as their countrymen depart for war. Each image confirms the precarious nature of Japanese discursive practice, revealing instead a mutual interplay that refuses dominance of one subject over the other.
Spaces of sympathy: The role of Asia in contempo-rary Japanese popular cinema
Authors: Hudson Seán
Published: November 2018

This paper provides an overview of two discourses in the study of Japanese popular film, while also bringing the two into conversation with one another in relation to their constructions of “Japan” and “Asia” as conceptual spaces. The discourse known as “victims’ history” is discussed first, drawing on a few relevant films as examples of how the war period is articulated in terms of Japanese suffering. The contemporary political implications of this apparatus within Japanese film are explored. For example, films such as Grave of the Fireflies (1988, Hotaru no Haka) have been internationally lauded for their pacifist stance, despite the fact that this pacifism is, I argue, constituted by the same victims’ narrative that sustains feelings of distrust towards Japan’s East Asian neighbours. In other words, we must consider these films not only in terms of passive victimisation, but also in terms of active erasure. The second discourse considered is that of “New Asianism”, or the modern boom in representations of Asia in popular films. Various commentators have forcibly challenged the idea that the internationalization of Japanese cinema (from the late 1980s to the present), both in terms of industry and narrative representation, has had a decolonizing effect on the Japanese cultural sphere. On the contrary, these films are accused of the exoticisation and Othering of Asia, and I argue they are therefore similar to victims’ history films in their positioning of Asia “outside” of the space of subjectivity.

Welcome to the fourth volume of Mutual Images.
 
This is the output of our fifth yearly international workshop, which our research association organised and held at Nagoya University (Japan) on 22 and 23 April, 2017. This workshop was organised in collaboration with G30 Japan-in-Asia Cultural Studies Program (JACS) from Nagoya University, directed by Kristina Iwata-Weickgenannt. This collaboration led to a geographical delimitation of both the workshop and this volume that differ from previous events and publications done by Mutual Images Research Association. In the previous volumes, the articles explored mainly the “images” bridging between Japanese and European cultures. For this volume, we seek to consider the representations between Japan and Asia. However, as it will become apparent with the articles that compose this volume, Europe is omnipresent. The relationship between Japan and Asia also goes through Europe as another “Other”. The concepts of Selfness and Otherness in and between Japan, other Asian nations and Europe are the common grounds that link the articles.

Primitive selves: Koreana in Japanese colonial gaze, 1910 – 1945 – E. Taylor ATKINS
Authors: Dischinger Kara
Published: November 2018

In 2010, E. Taylor Atkins published his book Primitive Selves: Koreana in Japanese Colonial Gaze, 1910-1945, seeking to make sense of the seemingly recent Japanese enthusiasm for Korean culture. As a historian of modern Japanese and Korean cultural history who focuses mainly on transnational popular culture, Atkins sought to prove that the twenty-first century South Korean, or hallyu, wave is not without historical precedent. This book positions itself within historical Japanese Imperial scholarship, focusing on cultural history rather than military or policy. Instead of concentrating on how the Japanese Imperial gaze of Korean culture shaped Korea through the imposition of Japanese culture onto the colonies, Atkins instead emphasises how the Japanese gaze on the Korean peninsula worked to shape the identity of the metropole, highlighting the importance of transnational flows on the creation of Self. The result is an interesting view into the complexities in the current and historical cultural connections between Japan and the Korean peninsula. Primitive Selves (2010), offers the reader a comprehensive and well researched look into the historical Japanese fascination with the Korean culture and traditions, something that continues to be relevant in an increasingly globalised world.
In his very detailed introduction, Atkins explains [...]
Rewriting History in manga: Stories for the nation –Nissim OTMAZGIN & Rebecca SUTER (Eds)
Authors: Hood Christopher
Published: November 2018

Workshops work. Many edited collections start life as papers and ideas presented at workshops. Rewriting History in Manga’s origins, according to text in the Acknowledgements, were in a workshop held at the University of Sydney in August 2012. One can imagine, from both the discussion in the book and from my own experience at workshops, that the project may have started from some ideas about testing new ground without necessarily knowing if it would, or could, lead to anything more significant. Not all research does go onto chapters in books, articles in journals or other outputs. That is the nature of research. The workshops are necessary as a mechanism for people to come together and test the water. And sometimes, the water is well and truly tested and from that it is possible to develop a coherent and interesting study. Rewriting History in Manga does this and reveals why workshops are so valuable.
Edited collections can work too. Whilst monographs arguably remain the gold standard, there has been [...]

Published: November 2018

In each touristic city waste management system has to overcome the impact of visitors. Dubrovnik, famous as popular touristic destination, particularly notices tourists visiting city. Therefore potential impact of waste management in touristic cities, such as Dubrovnik, is presented. The paper includes estimation of yearly waste production by inhabitants and tourists visiting those city. Waste digestion is a method for biogas production. On the basis of the preceding estimation combined-cycle installation generating heat and electricity is proposed. The model combines Brayton cycle with low temperature Kalina model based on Rankine cycle. Literature analysis presents state of the art in this field. The simulation is prepared in Cycle-Tempo. Numerical analyses lead to technical issues, which have to be taken into consideration during waste utilization with such installation. Thus benefits and threats are discussed. The presented analysis assesses the maximal electric gain, which subsequently should consider waste preparation and purification
