Representation of international students on Australian university websites: A critical multimodal discourse analysis

University websites play a pivotal role in the recruitment of international students for Australian universities, in particular at a time of fierce global competition. These websites make an interesting specialised genre for discourse analysis. This article conceptualises university websites as multimodal texts employing language and other semiotic resources such as images to represent international students in the context of shifting conceptualisations of international student education. Based on a qualitative inquiry into the webpages for international students on the official websites of three Australian universities, the article shows how the universities categorise international students and represent them in perceived activities and interpersonal relations through language and other modalities. The discursive representation of international students by the three Australian universities is discussed in relation to conceptual shifts in international student education, diversity management and multimodal discourse analysis. The article concludes with implications for international student representation and university webpage desUniversity websites play a pivotal role in the recruitment of international students for Australian universities, in particular at a time of fierce global competition.

An Automated Analyzer for Financial Security of Ethereum Smart Contracts

At present, millions of Ethereum smart contracts are created per year and attract financially motivated attackers. However, existing analyzers do not meet the need to precisely analyze the financial security of large numbers of contracts. In this paper, we propose and implement FASVERIF, an automated analyzer for fine-grained analysis of smart contracts' financial security. On the one hand, FASVERIF automatically generates models to be verified against security properties of smart contracts. On the other hand, our analyzer automatically generates the security properties, which is different from existing formal verifiers for smart contracts. As a result, FASVERIF can automatically process source code of smart contracts, and uses formal methods whenever possible to simultaneously maximize its accuracy. We evaluate FASVERIF on a vulnerabilities dataset by comparing it with other automatic tools. Our evaluation shows that FASVERIF greatly outperforms the representative tools using different technologies, with respect to accuracy and coverage of types of vulnerabilities

How Universities Introduce Themselves on the Internet: A Critical Multimodal Comparative Genre Study

This thesis reports on a study that examines Chinese universities’ self-introduction webpages in Chinese and English from a critical multimodal perspective. The study examines how the same genre provided by the same authorities is presented in the two different languages in response to the socio-cultural backgrounds, interests and goals of the two different audiences and sets of introductions. A corpus of 40 university webpages produced by different types of universities in China was analysed. Taking research in intercultural rhetoric as its starting point, the project draws on a number of different yet complementary analytical frameworks to compare the webpages produced in the two languages. In particular, it employs genre analysis, appraisal analysis, critical discourse analysis, and critical multimodal analysis to explore the relationship between the use of linguistic resources, non-linguistic resources and the socio-cultural contexts of the two sets of texts. The textual analyses are supplemented by discourse-based interviews with the people who were responsible for producing the webpages at the universities in China. The study shows how the universities shift their communication style and framing to suit the values and expectations of their different target audiences. The results of the study broaden the scope of comparative genre studies to include a context-sensitive, audience-oriented perspective, showing how contextual settings and expectations influence discourse practices at the textual, rhetorical and multimodal levels across the two sets of texts. The thesis closes by exploring implications of the research for improving sociocultural awareness of intercultural communication in translation, multi-semiotic language education, and media discourse studies across cultures

Estas páginas web constituyen un género especializado de interés para el análisis del discurso. En el presente artículo se conciben las páginas web universitarias como textos multimodales que emplean el lenguaje y otros recursos semióticos, como las imágenes, para representar a los estudiantes internacionales en un contexto cambiante sobre el concepto de la educación de estudiantes extranjeros. Basándonos en una investigación cualitativa de las secciones para estudiantes internacionales en las páginas web oficiales de tres universidades australianas, el artículo muestra cómo las universidades categorizan a estos estudiantes y los representan en actividades y en relaciones interpersonales percibidas a través del lenguaje y de otros modos semióticos. Además, se examina la representación discursiva de este grupo de alumnos en las tres universidades australianas en relación con los cambios conceptuales en la educación de los estudiantes internacionales, la gestión de la diversidad y el análisis multimodal del discurso. El artículo concluye con algunas implicaciones para la representación de los estudiantes internacionales y para el diseño de las páginas web universitaria

Optimal Design for an Extruder Head Runner Based on Response Surface Method and Simulated Annealing Algorithm

The head runner of a rubber extruder is important for controlling rubber flow and improving extrudate quality. To clarify the effect of the structure parameters of the head runner of a doubleplex tread extruder on extrudate quality and obtain high-quality rubber extrusions, a finite element model of the down head runner was established. The extrusion process was analyzed through numerical simulations, wherein the Bird–Carreau constitutive equation and Navier slip law were used along with some computational methods, such as quadratic interpolation of velocity and linear interpolation of pressure and viscosity. The Newton iteration algorithm was used for numerical calculations. The mean-square deviation of velocity (SDV) of rubber flow in the outlet cross section was selected as the evaluation objective. A Placket–Burman design was used to select three key factors—angles A and B and outlet width D—from among eight runner structure parameters affecting the velocity variance. By using central composite design (CCD), the quadratic response surface model using the three key factors was established, and the influence law of a combination of the three key factors on SDV was obtained. The response surface model was optimized using the simulated annealing (SA) algorithm, and the optimal key factors of the head runner were obtained. The optimal runner design realizes a more uniform velocity distribution in the outlet cross section. Furthermore, a comparison of the simulated flow velocities of the original and optimal head runners at different inlet flow ratios and temperatures indicates that the optimal head runner flow velocity improves the extrusion quality. Thus, an optimal runner with optimal key factors was manufactured. Test results of the rubber flow state indicated that the flow is regular and that warping disappears. The proposed optimization strategy can be used practically for improving the head runner design, shortening the product development cycle, and reducing the production cost

Concise and Efficient Multi-Identity Fully Homomorphic Encryption Scheme

Combining multi-key fully homomorphic encryption (MKFHE) and identity-based encryption (IBE) to construct multi-identity based fully homomorphic encryption (MIBFHE) scheme can not only realize homomorphic operations and flexible access control on identity ciphertexts but also reduce the burden of public key certification management. However, MKFHE schemes used to construct MIBFHE usually have complex construction and large computational complexity, which also causes the same problem for MIBFHE schemes. To solve this problem, we construct a concise and efficient MIBFHE scheme based on the learning with errors (LWE) problem. Firstly, we construct an MKFHE scheme using a new method called “the decomposition method”. Secondly, we make a suitable deformation of the current IBE scheme. Finally, we combine the above MKFHE scheme with IBE scheme to construct our MIBFHE scheme and prove its IND-sID-CPA security under the LWE assumption in the random oracle model. The analysis results show that our MIBFHE scheme can generate the extended ciphertext directly from the encryption algorithm, without generating fresh ciphertext in advance. In addition, the noise expansion rate is reduced from the polynomial of lattice dimension n and modulus q to the constant K of the maximum number of users. The scale of introduced auxiliary ciphertexts is reduced from $\tilde {O}(n^{4}L^{4})$ to $\tilde {O}(n^{2}L^{4})$ when generating the extended ciphertext

Quality Inspection Methods and Case Studies on Thematic Natural Resources Survey and Monitoring Results
