To identify the cause of edge waves and to minimize them, which are frequently occurring on the steel pipe manufacturing site, the shape of the edge part of skelp has been confirmed according to a design variable and operating condition. In particular, parametric studies were carried out on the variation in the thickness of skelp, tskelp, the roll gap between upper and bottom rolls, troll, at the forming stage 1, Forming 1, the roll shape, toffset, of the Forming 1, and the material property of skelp to study the generation of edge waves, because these parameters have been determined by field engineers extemporaneously without any physical estimation. For this purpose, the roll design and operating conditions used in the field were applied to the finite element analysis model, and the distribution of contact force between the rolls and skelp, and the distribution of effective plastic strain on the skelp were investigated. The fact that adjusting to tskelp and troll arbitrarily without changing to the roll shape can cause not only the edge waves but also the center waves, was carried out. Especially, the edge waves were reduced without the irregular contact pressure by changing the surface of the upper roll that is offset by target tskelp in the normal direction of the surface of the bottom roll in the Forming 1, when the target thickness is tskelp. Moreover, there is no significant difference in the vertical load applied to the rolls when high-strength steels are used or when low-strength steels are used, it is necessary to predict the local maximum and minimum of contact pressure between the skelp and rolls and the shape of the upper roll of the Forming 1 should be modified to decrease irregular contact pressure instead of any design modifications.

Study of equivalence classes of links up to n-moves plays an important role in the theory of invariants based on the skein relation and, in particular, skein modules. In this paper, we consider Nakanishi's 4-move conjecture [12]. The modification of the conjecture to 2-component link (homotopically trivial links) is a question proposed by Kawauchi [10]. We define a new invariant of links which is preserved by 4-moves and analyze its potential strength. In particular, we show that our invariant allows us to obtain results of [8, 9, 13] concerning 4-moves.

Using Chebyshev polynomials, C. Frohman and R. Gelca introduced a basis of the Kauffman bracket skein module of the torus. This basis is especially useful because the Jones–Kauffman product can be described via a very simple Product-to-Sum formula. Presented in this work is a diagrammatic proof of this formula, which emphasizes and demystifies the role played by Chebyshev polynomials.

Denne artikel giver et overblik over morfemets rolle i menneskelig sprogprocessering på basis af teoretisk morfologi, psykolingvistik og undersøgelser af dansk ordgenkendelse. Jeg beskriver først hvordan teoretisk morfologi arbejder ud fra enten morfembaserede eller ordbaserede modeller, trods problemer med både morfemet og ordet som teoretiske størrelser. Efterfølgende ser jeg på to relaterede men dog adskilte psykolingvistiske traditioner der begge fokuserer på morfologi: for det første den såkaldte datidsdebat der står mellem på den ene side modeller der skelner skarpt mellem regelmæssige og uregelmæssige ord, og på den anden side modeller der postulerer den samme processeringsmekanisme for alle typer ord; for det andet en bredere ordgenkendelseslitteratur der, i modsætning til datidsdebatten og dens fokus på engelske bøjningsformer, undersøger forskellige sprog og forskellige typer morfologi. Dernæst opsummeres resultaterne fra en række eksperimenter om dansk ordgenkendelse som overordnet set tyder på en funktionel rolle for morfologien. Samtidig viser forskelle mellem forskellige typer ord, komplekse frekvenseffekter og effekter af det lydlige signals overlap med andre ord i sproget et komplekst billede af morfologiens rolle. Til slut opsummeres morfologiens funktionelle rolle i sprogprocesseringen, og de videre perspektiver opridses med en opfordring til et kritisk blik på psykolingvistikkens traditionelle metoder og på både ordet og morfemet som teoretiske størrelser.

AbstractWe study the problem of the amplification of an ultra-short seed pulse via stimulated Raman backscattering (SRB) from a long pump pulse (assumed to have an envelope with a constant amplitude), in an underdense plasma. The SRB interaction couples the pump light wave to a daughter light seed wave propagating in the opposite direction, scattered off an electron plasma wave. In recent numerical simulations, it has been observed that besides stimulated Raman backward scattering (SRBS) and stimulated Raman forward scattering, other high-frequency kinetic instabilities can occur when modified distribution functions exist during the evolution of the system. In particular, we showed the prominent role played by kinetic electrostatic electron nonlinear (KEEN) waves (Afeyan et al., 2004). We continue this work by applying a relativistic Vlasov–Maxwell code to study stimulated KEEN wave scattering (SKEENS) and its role in the SRBS short pulse amplification processes. An analysis of the full spectrum of waves participating in the amplification processes is presented. The absence of spurious noise in grid-based Vlasov codes allows us to follow the evolution of the system with a kinetic (collisionless) description. This affords us a glimpse at the intricate phase-space structures such as trapped particle orbits, which coexist and interact nonlinearly in the electron distribution function.

Annotation:

Brazilian discussions of race between 1880 and 1940 were partly a use of European scientific theory to rationalise the native system of colour discrimination. When scientific orthodoxy turned against ‘race’ between 1920 and 1945, much of the intellectual racism of Brazil also dispersed. Quite rightly, most intellectual histories of race in Brazil stress a disjuncture around 1930. However, from the 1870s onward, and most clearly after abolition, there was also a medical-psychiatric strand to ‘race’ that can be unravelled from the rest of the skein. Part of racial thinking in Brazil reflected the general medicalisation of social thought that began when early-nineteenth-century physicians called for hygienic reforms within upper-class families to protect children from hereditary or environmental contaminations. The Spencerian and Comtean positivist social science that became fashionable in Brazil after 1870 also contributed to medicalisation. It saw society as an organism, and compared the role of the social scientist to the role of the physician: to examine symptoms of disease and propose therapies. From the 1880s through the 1920s, the national ailment that the medicalised social thought of Brazil most often diagnosed, an ailment that connected individual health to national well-being, was degeneration.

Annotation:

Human cytomegalovirus (HCMV) UL53 belongs to a family of conserved herpesvirus genes. In this work, the expression and localization of the UL53 gene product was analysed. Results obtained showed that pUL53 is a new structural protein. In infected human fibroblasts, pUL53 localizes in cytoplasmic perinuclear granular formations together with other structural viral proteins. In the nucleus, pUL53 forms patches at the nuclear periphery and co-localizes with lamin B at the internal nuclear membrane level. Immunoelectron microscopy studies have disclosed that nuclear pseudo-inclusions are labelled, whereas nucleocapsid formations within the intranuclear skein are negative. Furthermore, the mature virus particle maintains pUL53 at its tegumental level. These data suggest that pUL53 could be involved either in nucleocapsid maturation or in the egress of nucleocapsids from the nucleus to the cytoplasm through the nuclear membrane, a role compatible with the function hypothesized for UL31, its positional homologue in herpes simplex virus type 1.

Cryptography has distinct paramount significance in interconnected environment where whether we concern about ‘Computer-Security,’ ‘Information-Security,’ ‘Network-Security’ etc., doesn’t matters and, ingredients of this particular branch of computer science viz. ‘Encryption/Decryption’ systems, ‘Hash-Functions,’ ‘Digital-Signatures’ etc. also playing vital role from years in order to manage ‘Confidentiality,’ ‘Integrity’ and ‘Authenticity’ of resources. The Encryption/Decryption Cryptosystems managing the Confidentiality and Hash-Functions are fully devoted towards to look after the Integrity, Authenticity either alone or with Digital Signature schemes. There is a huge list of ‘Hash-Algorithms’ available with us to provide dedicated services (i.e., security) depends on how complex is to break it. Few renowned names are MD5, Blake, CRUSH, Grøstl, HAIFA, JH, Lake, SHA, Skein, Whirlpool etc., Keyed/Un-keyed constructions having its own justifiable capabilities. So in this direction we’re proposing a new secure keyed Hash-Function especially for military services where security is major concern apart from resource utilization which not only fulfilling basic properties but also providing justifiable services in order to manage integrity/authenticity of resources.

This chapter draws out some common threads from the history of emotions in Chinese literature. The first of these threads is orthodoxy. Specific Chinese traditions—and here Confucianism is the case in point—dictated the rules of proper behavior: these rules were considered to regulate even the emotions. The second thread is context. Whether, or how, an emotion was expressed was a product of the venue (textual or otherwise) in which it was to be described or expressed. The third thread is the role of the formula (or, the formulaic) in emotion and its expression, or how we understand professions and descriptions of emotion that are expressed via stock phrases.

This chapter focuses on Marga Richter's success with her modern dance scores and MGM music recordings during the period 1951–1960. After graduating from Julliard Graduate School, Richter moved to an apartment on 308 West 107th Street. In New York City, she was able to attend fine traditional and new music concerts, visit museums, and partake in the cultural life of the city. However, earning a living was a significant concern. Fortunately, Richter's music had drawn the attention of choreographer James Waring. This chapter first considers Richter's studies in New York and her marriage to Alan Skelly before turning to her early modern dance, piano, and orchestral works as well as compositions for children. It also examines Richter's beliefs and views on women's roles, along with her teaching pieces. Finally, it looks at Richter's concert music compositions commissioned by Edward Cole for recording by MGM, including Sonata for Piano (1954), Lament for string orchestra (1956), and Aria and Toccata for viola and string orchestra (1957).

Annotation:

Niobium’s role in the production of oil and gas transmission pipelines steels has gained significant importance in recent years. The economical movement of gas and oil to the marketplace from remote and rugged locations requires transmission pipelines to be designed to operate at higher pressures with improved toughness over a variety of temperature ranges. With the increased demand for energy resources continuing to grow, traditional plate mills, hot strip mills along with Steckel mills around the world are processing skelp for API pipe. The capabilities of these mills can be quite varied. Consequently, a variety of operational considerations and practices have put additional focus on Nb for its ability to retard recrystallization at elevated temperatures. This ability has added a new form of processing skelp for API pipe called High Temperature Processing or HTP. This new use of Nb in higher strength API oil and gas transmission pipeline steels allows a producer to create a ferrite/acicular ferrite microstructure without the traditional molybdenum alloy based design. The HTP Nb microalloy approach has benefits including reduced operating cost per ton, ease of rolling and welding, excellent low temperature toughness properties and high strength. This processing technique for API X70 and X80 is gaining acceptance as major pipeline projects are now applying this technology. In addition, X100 properties have been achieved with a combination of the traditional X80 alloy design and the newer employed HTP alloy design. This paper will discuss Nb’s role in meeting the increased strength requirements related to operating at higher pressures, improved low temperature toughness (TCVN > 200 J@−40 °C), microstructural demands and processing capability improvements for traditional plate, strip, and Steckel mill technology. The use of the new HTP concept in high strength API production will also be introduced.
