Reconstructed Ballistic Data Versus Wax Regression-Rate Intrusive Measurement in a Hybrid Rocket
Burning tests of a laboratory-scale hybrid rocket engine were carried out with gaseous oxygen and a microcrystalline-wax-based fuel to look into the feasibility of using an intrusive resistor-based sensor for measuring the fuel regression rate. This initial screening was driven by the need for real-time control of the oxidizer-to-fuel ratio in altering-intensity swirling-flow-type hybrid rocket engines aiming at performance optimization. A traditional ballistic reconstruction technique was critically revised in order to build up a framework for comparison with the measured data; with the measured aft-chamber pressure and oxygen mass flow rate time histories, the fuel regression rate and port diameter were reconstructed over the firing by estimating the combustion efficiency with the constraint that calculated and measured fuel mass consumed are equal. This technique invariably suffers from the issue of presenting multiple solutions for the fuel mass flow rate in the proximity of the optimum mixture ratio, for which a novel variable-efficiency approach is proposed. Reconstructed data show that regression rate is nearly constant in each firing, yielding dependence upon the port diameter other than the mass flux. Resistor-sensor raw data displayed large deviation from the ballistic results for the slower burning rate of the sensor support. A detailed analysis is presented

Japanese Modernism And Cine-Text : Fragments And Flows At Empire\u27s Edge In Kitagawa Fuyuhiko And Yokomitsu Riichi
This article notes that Kitagawa Fuyuhiko\u27s writings from the 1920s and 1930s, together with the contemporaneous works of prose author Yokomitsu Riichi, are strongly marked by the confluence of the literary and the cinematic. Kitagawa and Yokomitsu\u27s engagement with film was not limited to a fascination with the precision, objectivity, or mobility of the “camera eye.” Rather, it extended to the entire ability of the cinematic apparatus to capture the temporality of objects in motion, and of the ability of the filmmaker to organize segments of space into a new synthetic whole. The article explores this confluence through a brief examination of four instances of “cine-text”: Kitagawa\u27 poetry collection War, Yokomitsu\u27 novel Shanghai, the concept of literary formalism Yokomitsu proposed around the year 1930, and the theory of the “prose film” that Kitagawa unveiled in the following decade
Treatment Choice, Mean Square Regret and Partial Identification
We consider a decision maker who faces a binary treatment choice when their
welfare is only partially identified from data. We contribute to the literature
by anchoring our finite-sample analysis on mean square regret, a decision
criterion advocated by Kitagawa, Lee, and Qiu (2022). We find that optimal
rules are always fractional, irrespective of the width of the identified set
and precision of its estimate. The optimal treatment fraction is a simple
logistic transformation of the commonly used t-statistic multiplied by a factor
calculated by a simple constrained optimization. This treatment fraction gets
closer to 0.5 as the width of the identified set becomes wider, implying the
decision maker becomes more cautious against the adversarial Nature
The Whereabouts of "Falling" Stories\n―About the modernist YOKOMITSU Riiich and KITAGAWA Fuyuhiko
pdfYOSHIDA Seiichi evaluated YOKOMITSU Riichi and KITAGAWA Fuyuhiko because in Japanese literature “the novels of the 20th century” started with the former and the latter created “the spirit and style of poetry in the 20th century”. Not only YOKOMITSU and KITAGAWA had many common points - their fathers were railroad engineers, both of them had a connection in Otsu, Shiga Prefecture, for instance - but they also influenced each other in the concept of literature and admitted each other. That can be proved from the letter from YOKOMITSU to KITAGAWA, possessed in National Institute of Japanese Literature. In this letter YOKOMITSU praised KITAGAWA’s new prose poem Pigs, because this showed “a scene like a novel”. This poem, expressing the situation dynamically and visually, in which a freight train that carries pigs ran off the rails on the embankment and fell in the bottom of a valley, reminds of a thrilling movie scene. This really raised his honor, who also acted as a film critic later. Wanting to observe is that the motif of ‘falling’ or ‘tumbling down’ has appeared in Pigs, which also appears quite frequently in YOKOMITSU’s works. The construction whose story is cut off by the ‘fall’ of a character is fully pointed out by earlier studies about YOKOMITSU, however, also in KITAGAWA's work, poems that shockingly express the impact of the fall and the malfunction of the body sensation are seen here and there. Such a motif can be comprehended as a literary experiment for eliminating pathos thoroughly and expressing a sense of speed, or can be understood by relating to the view of life and death or difference between an artistic ideal and reality which are inside the author. If based on the fact that many of the Russian Revolution Dramas in the same era was performed using stairs, however, there may be the necessity which considers this motif of ‘falling’ as a cultural phenomenon beyond the individual intention . In The Battleship Potemkin, one of the classics in the film history, the director Sergei Eisenstein made the crowd fall by the famous ‘Odessa Steps’ sequence, too.
In this presentation, I would like to pay attention to the motif of YOKOMITSU and KITAGAWA who are called the modernist of Japanese literature, and reexamine the influence that the ‘fall’ gives to the whole story, also considering drama and movie in the same era.conference pape
THE IMAGE OF WOMEN IN JAPANESE CULTURE BASED ON WORKS KITAGAWA UTAMARO
У публікації розглянуто образ жінки в японській культурі на основі робіт Кітаґава Утамаро. Зазначено, що Кітаґава Утамаро майстерно зображує жінку, роблячи акцент на зачісці, одязі, обличчі та руках. Все це ставало предметом естетизму, виробленого художником, у своїх роботах автор виділяв не окремі особистості чи соціальні стани, а красу, формуючи свій власний образ жінки. Перед нами постають картини із буденного життя японських пані, проте вони самі наділені неземною легкістю, елегантністю, чуттєвістю та смаком. The publication examines the image of women in Japanese culture based on the works of Kitagawa Utamaro. It is noted that Kitagawa Utamaro skilfully portrays a woman, focusing on hair, clothing, face and hands. All this became the subject of aestheticism, developed by the artist, in his works the author did not single out individual personalities or social classes, but beauty, forming his own image of a woman. We are presented with pictures of the everyday life of Japanese ladies, but they are are themselves endowed with unearthly lightness, elegance, sensuality and taste

Robust Bayesian Inference in Proxy SVARs
We develop methods for robust Bayesian inference in structural vector autoregressions (SVARs) where the parameters of interest are set-identified using external instruments, or ‘proxy SVARs’. Set-identification in these models typically occurs when there are multiple instruments for multiple structural shocks. Existing Bayesian approaches to inference in proxy SVARs require researchers to specify a single prior over the model’s parameters, but, under set-identification, a component of the prior is never revised. We extend the robust Bayesian approach to inference in set-identified models proposed by Giacomini and Kitagawa in press[a] – which allows researchers to relax potentially controversial point-identifying restrictions without having to specify an unrevisable prior – to proxy SVARs. We provide new results on the frequentist validity of the approach in proxy SVARs. We also explore the effect of instrument strength on inference about the identified set. We illustrate our approach by revisiting Mertens and Ravn (2013) and relaxing the assumption that they impose to obtain point identification
