Newly-designed high-rise buildings, both in China and abroad, have demonstrated new innovations from the creative concept to the creative method. from the creative concept to the creative method. At the same time, digital technology has enabled more design freedom in the vertical dimension. "Twisting" has gradually become the morphological choice of many city landmark buildings in recent years. The form seems more likely to be driven by the interaction of aesthetics and structural engineering. Environmental performance is often a secondary consideration; it is typically not simulated until the evaluation phase. Based on the research results of "DigitalFUTURE Shanghai 2017 Workshop - Wind Tunnel Visualization", an approach that can be employed by architects to design environmental-performance buildings during the early stages has been explored. The integration of a dynamic form-finding approach (DFFA) and programming transforms the complex relationship between architecture and environment into a dialogue of computer language and dynamic models. It allows the design to focus on the relationship between morphology and the surrounding environment, and is not limited to the envelope form itself. This new concept of DFFA in this research consists of three elements: 1) architectural form; 2) integration of wind tunnel and dynamic models; and 3) environmental response. The concept of wind tunnel testing integrated with a dynamic model fundamentally abandons the functional definition of the traditional static environment simulation analysis. Instead it is driven by integral environmental performance as the basic starting point of morphological generation.

Seats in autonomous vehicles must be able to rotate to fully utilize the interior space. Generally, ultra-high strength steel is used for the rotation module because it should have high strength and high rigidity. In addition, the rotating parts are difficult to form because they have complex shapes. In this study, the upper plate of the rotating module, whose complex shape makes it difficult to form, was formed by applying the hot stamping method. The drawing method and the form-drawing method, which are generally used to form components of complex shapes, were compared. We showed that the form-drawing method increased the degree of freedom of the material flow to improve the formability, thus enabling the forming of the plate. In addition, the die and blank shapes were found to be important factors in determining the success of the hot stamping. The validity of the analysis results was confirmed through forming analysis and experiments.

Fine art and fashion have influences on each other since both of them are the part of a culture. The similar patterns of fine art and fashion can be found either in the same period or in the different time. To find out this fact in the forms or content, this study researched into the fine art and fashion of 1960s and into recent year's fashion to see the revivals. In 1960s, fine art and fashion laid emphasis on the materiality of material itself, therefore both fine art and fashion have the tendency of formlessness and disorder in form. It ran be said that the socio-cultural background of this phenomenon in 1960s was mainly caused by the young generation called Hippies. They became a large influential social group that has a huge impact on overall culture in 1960s. As a result, this study firstly found that the fine art and fashion had common formative features and content in 1960s. Secondly, fashion since 1990 repeats the similar features in form like the Post-minimal tendency in fine art in 1960s. The similar features can be described as: artworks have the tendency of the formlessness and disorder in appearances; various materials were newly used to form a work, which had never been used in traditional artworks; new methods such as hanging, layering and knotting were applied to show the maximum expression of the materiality. However, unlike the fashion of 1960s, the Post-minimal tendency in fashion since 1990s doesn't symbolized freedom or peace, or opposition to the war anymore. Instead, only the formative elements were revived and reproduced and the formless tendency became one of the recent fashion trends.

본 논문의 목적은 2018년부터 넷플릭스에서 상영된 <블랙 미러: 밴더스내치>의 형식적 특성에 대해 알아보고 그것의 의미를 해석하는 것이다. 이 콘텐츠는 시청자에게 사건 진행을 선택할 수 있도록 하고 이에 따라 각기 다른 결말이 나타나기 때문에 일종의 상호작용적 서사로 볼 수 있다. 그러나 여러 가지 방식으로 상호작용이 제한되는 경우도 있어서 수용자는 선택의 자유를 충분히 누리지 못한다. 또한 여러 결말에서 공통적으로 <블랙 미러> 시리즈에 전형적인 테크놀로지 비판의 주제가 나타나는데, 그래서 <밴더스내치>를 전통적 서사의 일종으로 간주할 수도 있다. 이러한 이중적인 서사의 상황 때문에 사용자의 선택 가능성과 작가의 서사적 권위는 충돌하게 된다. 그리고 그 충돌로 말미암아 복잡한 형식이 발생하는데, 그것은 비선형적 상호작용성과 선형적 서사 형식 사이의 중간적인 것이며, 혹은 두 가지가 융합된 결과이다. 그리고 그것을 메타렙시스 또는 제4의 벽을 파기하는 형식과 같은 자기반영의 형식으로 이해할 수 있다. 본 논문에서는 이러한 특수한 형식을 통해 성찰적 상호미디어성, 즉 일종의 융합 형식을 통한 미디어의 자기성찰이 이루어질 수 있음을 설명해 보고자 한다.

This work proposes a theoretical and numerical study on the behavior of a tapered shaft rotor made of composite materials by the classical version h and the version p of the finite element method. Hierarchical form functions are used to define the model. The purpose of this paper is to determine the expressions of the kinetic and potential energies of the tree necessary for the results of the equations of motion. A comparison between the version h and the p version of the finite element method of the functions of polynomial and trigonometric hierarchical forms with six degrees of freedom per node, of a composite tapered and cylindrical shaft which rotates at a constant speed about its axis. It is found that when the number of functions of form (the version p) is increased, the solution converges. It is also observed that the conicity of the shaft increases the rigidity with respect to a uniform shaft having the same mechanical properties. The numerical simulation allowed us to determine the natural frequencies and the critical speeds of the composite shaft systems are compared with those available in the literature and the effectiveness of the methods used are discussed.

A novel flexibility-based beam-foundation model for inelastic analyses of beams resting on foundation is presented in this paper. To model the deformability of supporting foundation media, the Winkler-Pasternak foundation model is adopted. Following the derivation of basic equations of the problem (strong form), the flexibility-based finite beam-foundation element (weak form) is formulated within the framework of the matrix virtual force principle. Through equilibrated force shape functions, the internal force fields are related to the element force degrees of freedom. Tonti's diagrams are adopted to present both strong and weak forms of the problem. Three numerical simulations are employed to assess validity and to show effectiveness of the proposed flexibility-based beam-foundation model. The first two simulations focus on elastic beam-foundation systems while the last simulation emphasizes on an inelastic beam-foundation system. The influences of the adopted foundation model to represent the underlying foundation medium are also discussed.

The transition from "More-of-Less" markets (economies of scale) to "Less-of-More" markets (economies of scope) is supported by advances of disruptive manufacturing and reconfigurable-supply-chain management technologies. With the prevalence of cyber-physical manufacturing systems, additive manufacturing technology is of great impact on industry, the economy, and society. Traditionally, backbone structures are built via bottom-up manufacturing with either pre-fabricated building blocks such as bricks or with layer-by-layer concrete casting such as climbing form-work casting. In both cases, the design selection is limited by form-work design and cost. Accordingly, the tool-less building of architecture with high design freedom is attractive. In the present study, we review the technological trends of additive manufacturing for construction-scale additive manufacturing in particular. The rapid tooling of patterns or molds and rapid manufacturing of construction parts or whole structures is extensively explored through uncertainties from technology. The future regulation still has drawbacks in the adoption of additive manufacturing in construction industries.

This paper is to analyze how Walt Whitman developed the theme and structure of Leaves of Grass with his ideal of democratic vistas. Whitman established his identity as an inspired poet, having faith in the divinity of man based on transcendental belief. After being awakened to the transcendental truth, he practiced his own common world view--his democratic vistas. Whitman searched for the unity with nature and identified his self with "common man and his nation." The poetry expresses "cosmological and national ideology" dedicated to the creation of an ideal nation united in eternal freedom and peace. By portraying common cosmic and national theme in terms of his individual personality, he brought various paradoxical and controversial ideas into one thing, namely "democracy", fusing diversity into unity. As in the symbol of the grass, there is a unity in variety reflected by democracy in a cosmological and political compound. With the form of free verse, he could express his liberal unrestrained and mystical thoughts of democracy. This new form has been associated with the poet's strong consciousness of the need for modernization in his country. He willingly assumed "the role of prophet and public voice for American democrat" with the rolling catalogues and I-persona which formed a sense of the common man and common things of America. Whitman pioneered a democrat literature with simple and dynamic tone and style. He successively pursued the democratic vistas in his Leaves of Grass.

In this paper, a new kinematic structure of a parallel manipulator with six Cartesian degrees of freedom is proposed. It consists of a platform which is connected to a fixed base by means of 3-PPSP(parameters P, S denote the prismatic, spherical joints) subchains. Each subchain has a link which is concected to a passive prismatic joint at the one end and a passive spherical joint at the other. The spherical joint is then attached to perpendicularly arranged prismatic actuators which are fixed at the base. The spherical joint is then attached to perpendicularly arranged prismatic actuators which are fixed at the base. This arrangement provides a basis to control all six Cartesian degrees of motion of the platform in space. Due to its efficient architecture, the colsed-form solutions of the inverse and forward kinematics can be obtained. As a consequence, this new kinematic structure can be servo controlled using simple inverse kinematics becaese forward kinematics allows for measuring the platform's position and orientation in Cartesian space. Furthermore, the proposed structure provides an effective functional workspace. Series of simulations are performed to verify the results of the kinematics analyses.
