Observation of Dynamic State Parameters and Yaw Stability Control of Four-Wheel-Independent-Drive EV

Vehicle yaw stability control is an important part of the active safety of electric vehicles. In order to realize the yaw stability control of vehicles, this paper takes 4-WID electric vehicles as the research object, studies the nonlinear estimation of the state parameters of the lateral stability dynamic system and the yaw stability control strategy. The vehicle state parameter estimation strategy, based on the unscented Kalman filter (UKF) algorithm and the model predictive control algorithm, are designed to control the vehicle yaw stability, which realizes the safe and stable driving of the vehicle. Through CarSim–Simulink joint simulation and hardware-in-the-loop (HIL) experiments based on MicroAutoBox, the effectiveness and real-time performance of the designed control strategy are fully verified, which accelerate the development process of the vehicle controller, and realizes the safe and stable driving of the vehicle.

Improving Safety of Shielding Chambers Equipped with Viewing Windows

The article describes and proves the possibility of increasing the protection against neutron radiation for personnel by means of immersion liquid without major changes in the design of the equipment used and without reducing the safety of the radiation object. Studies of the components properties of the protection glass and the immersion liquid have shown that the properties of the immersion liquid reduce the dose rate of neutron radiation significantly compared to the protection glass, which is used for the main protection against ionizing radiation when working with uranium-plutonium fuels. The use of two-layer protection in viewing windows allows reducing the dose rate of mixed gamma-neutron radiation to values that do not exceed the safe radiation dose for personnel when working with an ionizing radiation source, which in this case is 50 kg of uranium-plutonium fuel

Citra Inferioritas Tenaga Kerja Wanita (TKW) Indonesia di Saluran Berita Sabq.Org Saudi Arabia

This article is the result of research, one of which is the lack of discourse studies, especially the representation of the news object studies in electronic newspapers. News about woman employees in Saudi Arabia was chosen because there have been many cases that occurred in Saudi Arabia. Several cases such as starting from illegal migrant workers, trafficking, prostitution, suicide, and various legal circumstances that befall Indonesian workers, how the news of women employee is written on Sabq.org newspaper, one of the leading online publications in Saudi Arabia. All cannot be separated from the media representation or depiction of an object. Representatives of woman employees will be dissected based on contextual illustration-writer-text-context reader theory by Sara Mills. The qualitative method of Critical Discourse Analysis was chosen as a means for collecting data. The technique of analyzing data used in this study is using the framework of Sara Mills's analysis related to the position of subject and object of the news. The research findings showed that Sabq.org portrays woman employees poorly, marginalizes minority groups by not showing woman employees in the news, dominant groups represent their presence, establishing ideology of dominant groups (employee) and tends to be gender-biased. Artikel ini dilatarbelakangi minimnya kajian wacana, khususnya representasi pada objek kajian berita pada surat kabar elektronik (SKE). Berita tentang Tenaga Kerja Wanita (TKW) di Arab Saudi menjadi pilihan karena alasan banyaknya kasus yang terjadi pada TKW di Arab Saudi, mulai dari TKI ilegal, kasus trafficking, prostitusi TKW, bunuh diri dan beragam kasus hukum yang menimpa buruh migran wanita Indonesia. Bagaimana wacana TKW digambarkan dalam berita Sabq. Org, salah satu koran online terkemuka di Arab Saudi tidak lepas dari representasi atau penggambaran media atas suatu objek. Representasi TKW akan dibedah dengan teori ilustrasi konteks penulis- teks-konteks pembaca dari Sara Mills. Metode kualitatif Analisis Wacana Kritis (critical discourse analysis) dipilih sebagai alat mencari data. Teknik analisis penelitian ini menggunakan kerangka analisis Sara Mills terkait posisi subjek-objek berita. Hasil dari penelitian ini adalah Sabq.Org menggambarkan TKW dengan buruk, memarjinalkan kelompok minoritas (TKW) dengan tidak menampilkan TKW dalam pemberitaan, kehadirannya diwakili oleh kelompok dominan, memapankan ideologi kelompok dominan (majikan) dan cenderung bias gender.

Modernism and Middlebrow through the Eyes of Object Studies

This chapter argues that an object-orientated approach puts texts from a range of cultural registers into dialogue with one another and fruitfully reconfigures how a high modernist work like Virginia Woolf’s Three Guineas might be read on its own. After providing examples of how a range of British and American authors and illustrators (including Rachel Ferguson, Winifred Kirkland, James Joyce, Bert Thomas, and Woolf) represent second-hand attire, the chapter examines the new tools and resources available to scholars that make a research project organized around objects possible. The chapter concludes by examining challenges to object-oriented study, including the difficulty of determining the range and scope of a project and the resistant qualities of things themselves. A gown designed by Sarah Fullerton Monteith Young, a court dressmaker who produced the garments worn by Virginia and Vanessa Stephen when they made their society debut, serves as an example of what we can and cannot know about objects and the people who possessed them.

Forward modeling of galaxy kinematics in slitless spectroscopy

Context. Slitless spectroscopy has long been considered a complicated and confused technique. Nonetheless, with the advent of Hubble Space Telescope (HST) instruments, characterized by a low sky background level and a high spatial resolution (most notably WFC3), slitless spectroscopy has become an adopted survey tool to study galaxy evolution from space. Aims. We aim to investigate its application to single-object studies to measure not only redshift and integrated spectral features, but also spatially-resolved quantities such as galaxy kinematics. Methods. We built a complete forward model to quantitatively compare actual slitless observations. This model depends on a simplified thin cold disk galaxy description – including flux-distribution, intrinsic-spectrum, and kinematic parameters – and on the instrumental signature. It is used to improve redshifts and constrain basic rotation curve parameters, meaning the plateau velocity v0 (in km s−1) and the central velocity gradient w0 (in km s−1 arcsec−1). Results. The model is tested on selected observations from 3D-HST and GLASS surveys to estimate redshift and kinematic parameters on several galaxies measured with one or more roll angles. Conclusions. Our forward approach makes it possible to mitigate the self-contamination effect, a primary drawback of slitless spectroscopy, and therefore has the potential to increase precision on redshifts. In a limited sample of well-resolved spiral galaxies from HST surveys, it is possible to significantly constrain galaxy rotation curve parameters. This proof-of-concept work is promising for future large slitless spectroscopic surveys, such as Euclid and WFIRST.

Fashion parades – for men only: Multiple tailor Hepworths, designer Hardy Amies and the marketing of men’s suits in Britain in the 1960s

This article will examine the use of male fashion shows as a marketing and promotional tool by British high street multiple tailor Hepworths in the 1960s as part of their design collaboration with women’s fashion designer and couturier Hardy Amies. The partnership successfully brought the concept of the branded designer label to British men for the first time and was a major initiative for the menswear industry as it highlighted and consolidated a design ethos which strongly emphasized men’s fashion. Drawing on a wide range of primary source material including oral history interviews with two male models who worked for Hepworths and Amies; object studies of surviving garments; and film and images of the shows, this article will explore the significant and innovative approach to selling men’s fashionable tailoring taken by this mid-market menswear company. It also provides a broader understanding of the history of men’s fashion during this period, a narrative which is dominated by the concept of the peacock revolution, by demonstrating Hepworths’ important contribution to everyday men’s fashion in post-Second World War Britain.
