A Multimodal and Pragmatic Analysis of the Environmental-Friendly Corporate Identity of Apple

As environmental problems become increasingly serious, people are more aware of the importance of the environmental protection. Accordingly, companies have realized the necessity and significance of constructing an environmental-friendly identity. Environmental-friendly corporate identity is currently receiving an increasing amount of attention in the literature on corporate identity construction. The present study has continued that focus by investigating the environmental-friendly corporate identity of Apple. The new product conference, which is held online by Apple in October, 2020 is chosen as the research material. The present study is different from previous research on new product conferences or corporate identities, for it offers a multimodal analysis of the data within the framework of the Relevance Theory. The purpose of the study is to explore how Apple constructed its environmental-friendly corporate identity while rationalizing its announcement in the new product conference. Findings from the study indicate that the environmental-friendly corporate identity of Apple is constructed in the new product conference through the interplay of main modes, such as language, visual images, gaze and gestures. The findings of the study not only contribute to prove the feasibility of multimodal analysis of the new product conference under the Relevance Theory, but also shed light on the studies of environmental-friendly corporate identity construction

Automation System Vibration Analysis Taking Environmental Factors into Consideration

This paper aims to investigate the vibration behavior of a propulsion system subjected to hull deformations ina two dimension circumstance. As known that large scale ships have great developments in recent years which could cause much severer conditions among the interaction between the propulsion system and ship hull. Excited forces from thesea waves could make the ship hull deformed which further cause drastic vibrations of the shaft system. As a result, the malfunctions of shaft propulsion system are potential existed as the vibrations of the shaft always exceed its maximum allowable values.This paper establishes a simplified model of the large ship propulsion-hull system to analyze the vibration behavior of the ship propulsion system subjected to the ship hull deformations. The hull deformations were obtained as the excited forces under different sea conditions. Then base on the simplified 2D model, the effects of propeller, supports stiffness, the location of hull excitations, the amplitude of excitations are discussed.

Reduced fidelity approach for quantum phase transitions in spin-1/2 dimerized Heisenberg chains

We use reduced fidelity approach to characterize quantum phase transitions in the one-dimensional spin-1/2 dimerized Heisenberg chain in the antiferromagnetic case. The reduced fidelity susceptibilities between two nearest-neighboring spin pairs are considered. We find that they are directly related to the square of the second derivative of the ground-state energy. This enables us to conclude that the former might be a more effective indicator of the second-order quantum phase transitions than the latter. Two further exemplifications are given to confirm the conclusion is available for a broad class of systems with SU(2) and translation symmetries. Moreover, a general connection between reduced fidelity susceptibility and quantum phase transitions is illustrated.Comment: 6 pages, 2 figure
