Abstract

This paper sets out to investigate Chinese university students’ ELF awareness, which is conceptualised with regards to language education. The study, based on 24 semi-structured interviews, demonstrates that Chinese university students are still framing their understanding of English with the affiliation to idealised notions of monolingual origin of native English, despite being situated in a changing world where multilingual speakers of English are becoming the majority of English users and ELF is becoming a prominent communicative phenomenon. The participants’ account reveals the role of language education as the interface between language ideology and linguistic reality in China. Based on the study, this paper suggests ways of minimising the gap in ELF awareness. While this paper appreciates Chinese philosophy of education, the focus is on promoting awareness of English in relation to its sociocultural context and considering “imagined communities” in the learning so as to come to terms with sociolinguistic reality.

Abstract

This article examines the cultural practice of effecting an independent marketplace for reissued music in the United States, based on ethnographic fieldwork in Austin, Texas with independent record labels and consumers. As the music industry is not a homogenous entity (Williamson and Cloonan, 2007), I argue that the practice of legitimising an independent marketplace requires the formulation of a ‘mainstream’ market to which the independent is opposed, and the erecting of marketplace myths (Arsel and Thompson, 2010) to substantiate the independent marketplace’s claims to differ from the mainstream. Legitimising strategies (Strachan, 2007) protect the investments made by producers and consumers of goods in their marketplace. To overcome the anxiety that commodified culture is inauthentic culture, the independent marketplace for reissued music is idealised as a realm of soft capitalism that enables the commodification of cultural goods without the stigmatisation of profiteering, exploitation and ‘inorganic’ music associated with the mainstream (Negus, 1992).

Abstract

This paper presents of the optimal design of the damping devices cover of reactor hall under impact of nuclear fuel container drop of type TK C30. The finite element idealization of nuclear power plant structure is used in software ANSYS. The steel pipe damper system is proposed for dissipation of the kinetic energy of the container free fall in comparison with the experimental results. The probabilistic and sensitivity analysis of the damping devices was considered on the base of the simulation methods in program AntHill using the Monte Carlo method.

Reliable Robust Path Planning with Application to Mobile Robots

This paper is devoted to path planning when the safety of the system considered has to be guaranteed in the presence of bounded uncertainty affecting its model. A new path planner addresses this problem by combining Rapidly-exploring Random Trees (RRT) and a set representation of uncertain states. An idealized algorithm is presented first, before a description of one of its possible implementations, where compact sets are wrapped into boxes. The resulting path planner is then used for nonholonomic path planning in robotics.

Abstract

The paper presents the stages of quantitative coefficient of marine seismic researches creation for the geophysical vessels towing the geophysical seismic equipment understood as system of seismic streamers where set of geophones are installed. The quality coefficient of geophysical research works is based on the mathematical model of the deviation of the position of the arrangement of streamers geophone points with relation to their idealized position. The proposed coefficient can be used during realization of seismic researches and for short-term prediction of their quality.

Abstract

In this paper, a simple generalization of Darcy’s law is proposed for the description of hydraulic properties of anisotropic porous materials. The coefficient of permeability is defined as a scalarvalued function of orientation. The principal directions of permeability are determined from a fabric descriptor specifying the distribution of average pore size. An example is provided for identification of material parameters, which is based on an idealized “pipe network model”. A procedure for defining the anisotropy in strength properties, which incorporates a conceptually similar approach, is also reviewed and an illustrative example is provided.

Deterministic and probabilistic analysis of damping device resistance under impact loads from nuclear fuel container drop

This paper presents a deterministic and probabilistic solution of damping devices for the protection of the reinforced concrete structure of a nuclear power plant (NPP) from impact loads from a container of nuclear fuel of the type TK C30 drop. The finite element idealization of the building structure is used in space. The interaction soil-structure, as well as the fluid-structure of the deactivated basin is considered in space. A steel pipe damper system is proposed for the dissipation of the kinetic energy of the container in free fall. The Newmark integration method is used for the solution of the dynamic equations. The sensitivity and probabilistic analysis of the damping devices was realized using the AntHILL and ANSYS software.

Abstract

Since the second half of the 19th century, the notion of beauty has been gradually losing its classical meaning. More and more often, our aesthetic tastes are met by that which is violent and based on creaking dissonances. Similarly, the body of a contemporary human is perceived today in a different way than it was in ancient Rome or Greece. The attractiveness of body depends now to a lesser extent than then on the arrangement of its build, appearance, and function into a harmonious whole, reflecting the idealized world of nature. The sentimentalism of the beautiful is being replaced by the aesthetics of functional machinery, and what was until recently rejected with disgust begins to be considered desirable. Not condemning all these occurrences in advance, it is worth considering if this re-aesthetization of human body is beneficial to the humanity.

Abstract

In the present study, external restraints imposed normal to the plate during the cooling stage were determined to be effective for reduction of the angular distortion of butt-welded or fillet-welded plate. A welding analysis model under external force during the cooling stage was idealized as a prismatic member subjected to pure bending. The external restraint was represented by vertical force on both sides of the work piece and bending stress forms in the transverse direction. The additional bending stress distribution across the plate thickness was reflected in the improved inherent strain model, and a set of inherent strain charts with different levels of bending stress were newly calculated. From an elastic linear FE analysis using the inherent strain values taken from the chart and comparing them with those from a 3D thermal elasto-plastic FE analysis, welding deformation can be calculated.

Abstract

The paper g describes a model meant for analysis of the wear geometry of plain woven fabric composites. The referred model consists of a mathematical description of plain woven fabric based on Peirce’s model coupled with a stratified method for the solution of the wear geometry. The evolutions of the wear area ratio of weft yarn, warp yarn and matrix resin on the worn surface are simulated by MatLab software in combination of warp and weft yarn diameters, warp and weft yarn-to-yarn distances, fabric structure phases (SPs). By comparing theoretical and experimental results from the PTFE/Kevlar fabric wear experiment, it can be concluded that the model can present a trend of the component area ratio variations along with the thickness of fabric, but has a inherently large error in quantitative analysis as an idealized model.
