Skripsi ini membahas mengenai kehadiran skin yang dinamis pada arsitektur yang rigid. Melalui penerapan konsep pakaian pada perspektif fashion ke dalam arsitektur. Dimana pakaian dan skin memiliki irisan pada fungsinya, yaitu merupakan lapisan terluar atau kulit kedua yang berperan sebagai pelindung. Diskusi dinamika skin sebagai permukaan terluar pada arsitektur kerap hanya berelasi dengan performa arsitektur itu sendiri tanpa terhubung dengan sekitarnya. Sifat dinamis dapat terjadi melalui interaksi skin terhadap elemen lingkungan sekitar. Elemen lingkungan sekitar berperan sebagai stimulan yang akan mengidentifikasi sifat dinamis pada skin. Stimulan dapat berupa nature element dan culture element yang sifatnya selalu berubah dan tidak dapat dipastikan. Stimulan bersifat selalu berubah, sehingga ketika skin dapat merespon stimulan tersebut menghasilkan dynamic response yang merupakan performa transformatif. Performa transformatif bekerja secara terus-menerus hingga membentuk kualitas temporal dalam arsitektur. Studi ini mengeksplorasi adaptasi tersebut melalui studi kasus dari respon skin bangunan The Bund Finance Centre terhadap angin dan respon proyeksi visual warna Evoke pada fasad bangunan Katedral York Minster terhadap kebisingan sekitar. Skin yang terus bertransformasi dan menghasilkan bentuk ataupun kualitas temporalitas baru. Transformasi yang terjadi pada skin mengungkapkan bahwa bangunan dapat merespon perubahan lingkungan secara real-time melalui skin. Pemahaman akan transitory skin mampu memperlihatkan bahwa memiliki keterhubungan temporal dengan sekelilingnya yang kemudian dapat menghadirkan kemampuan elemen-elemennya untuk berinteraksi dan beradaptasi dengan perubahan lingkungan sekitar. ......This study discusses the presence of dynamic skin in rigid architecture through the application of clothing concepts from a fashion perspective. Both clothing and skin share a functional overlap as the outermost layer or second skin, acting as a protective barrier. Discussions on the dynamics of skin as the outer surface in architecture often focus solely on the architecture's performance without considering its connection to the surrounding environment. The dynamic nature of the skin can occur through its interaction with the surrounding environmental elements. The surrounding environmental elements act as stimuli that identify the dynamic properties of the skin. These stimuli can take the form of natural and cultural elements, which are constantly changing and unpredictable. As the stimuli are always changing, when the skin can respond to these stimuli, it produces a dynamic response, resulting in transformative performance. Transformative performance operates continuously to shape temporal qualities within the architecture. This study explores such adaptation through case studies of the skin response of The Bund Finance Centre to wind and the visual projection response of Evoke's color on the facade of York Minster Cathedral to surrounding noise. The continuously transforming skin generates new forms or temporal qualities. The transformations occurring in the skin reveal that buildings can respond to environmental changes in realtime through their skin. Understanding the transitory skin demonstrates its temporal connection to its surroundings, enabling its elements to interact and adapt to changes in the surrounding environment.

Statics and dynamics of rigid bodies presents an interdisciplinary approach to mechanical engineering through a close evaluation of the statics and dynamics of rigid bodies, presenting a concise introduction to both. This volume bridges the gap of interdisciplinary published texts linking fields like mechatronics and robotics with multi-body dynamics in order to provide readers with a clear path to understanding numerous sub-fields of mechanical engineering. Three-dimensional kinematics, rigid bodies in planar spaces and numerous vector and matrix operations are presented in order to provide a comprehensive understanding of mechanics through dynamics and rigid bodies.

This book contains a unique description of the nonholonomic motion of systems of rigid bodies by differential algebraic systems. Nonholonomic Motion of Rigid Mechanical Systems from a DAE Viewpoint focuses on rigid body systems subjected to kinematic constraints (constraints that depend on the velocities of the bodies, e.g., as they arise for nonholonomic motions) and discusses in detail how the equations of motion are developed. The authors show that such motions can be modeled in terms of differential algebraic equations (DAEs), provided only that the correct variables are introduced. Several issues are investigated in depth to provide a sound and complete justification of the DAE model. These issues include the development of a generalized Gauss principle of least constraint, a study of the effect of the failure of an important full-rank condition, and a precise characterization of the state spaces. In particular, when the mentioned full-rank condition is not satisfied, this book shows how a new set of equivalent constraints can be constructed in a completely intrinsic way, where, in general, these new constraints comply with the full-rank requirement. Several equivalent DAE formulations are discussed and analyzed thoroughly. The value of these DAE models rests upon the premise that they are more accessible than others to an effective numerical treatment. To substantiate this, a numerical algorithm is presented and numerical results for several standard problems are included to demonstrate the efficiency of this approach.
