Circle Limit

The Dutch graphic artist Escher was very much interested in plane symmetry. He was fascinated by the problem of infinity and the representation of infinity on a sheet of paper. An exchange of ideas with Coxeter was the origin of the series of works called "Circle Limit". This article also describes the animation technique, which by adding time and movement to the images of Escher try to contribute to Escher's dream of reaching infinity.

Constant Force Mechanism

A means of synthesis of single-input and multiple-output port mechanisms for specified energy absorption is formulated for multiple precision points. The synthesis presented makes use of an extension of the loop closure method which includes expressions for energy absorption by linear spring elements. The configuration considered locates spring elements at two output ports of a multi-loop, planar mechanism. Economies realized for the symmetric mechanism are discussed for both one- and two-plane symmetry. Synthesis examples are included for both the general and symmetric mechanism. Special applications presented include synthesis of a constant force mechanism and synthesis of a mechanism suited to the energy absorption requirements of an automotive crashworthiness system.

Pathological Image

On the example of the work «The Great Neurosis» by the French sculptor Jacques Loysel and «Europe» by the Austrian graphic artist Alfred Kubin, it is described and analyzed how artists gave characteristics of changes in their eras, using the same visual image associated with a mental illness. It is proved that while Loysel’s artwork was associated with the latest discoveries in medicine, then Kubin’s artwork was reinterpreted in a new way, reflecting the problems and experiences of the «lost generation». From this it follows that the example of the works «The Great Neurosis» and «Europe» by Loysel and Kubin can be traced not only to evolution, but also to the introduction of the pathological image of the “hysterical body” both in the art of the XXth century and in contemporary art practices. Such a study demonstrates the relevance and signifi cance of studying the links between, as well as the analysis of the impact of mechanisms of institutions of disciplinary power on the visual arts of various eras.

The Creation

Rockets are spacecraft, missiles, or flying vehicles that get a boost through rocket reactions to fluid materials. In this film the rocket represents dreams and hopes. The process of launching a rocket is the process of reaching someone's dream. The process of launching missiles into space is not easy, but that doesn't mean it can't. This film, invites the audience to be sure of hope and dare to fight for it. The creation of this animated film is presented in the form of 2D animation without using any narration or dialogue. As a support for the atmosphere, music is created that can build an atmosphere. Not forget the 12 principles of animation applied in this animated film to strengthen and improve the artistic impression as a support of visualization. The twodimensional animation technique is intentionally used because the visual form of 2D animation has a light but easy to remember impression.

Instantaneous Values

The motions of a deeply submerged body with vertical-plane symmetry, e.g., a submarine, are commonly treated in a manner completely analogous to that used for aircraft motions. The body is assumed to have its lateral and longitudinal modes uncoupled. The small motions are described by a set of force-and-moment equations which are linear, second-order differential equations with constant coefficients. These proportionality constants ("stability derivatives") relate the forces and moments to the instantaneous values of the position, velocity, and acceleration of the body. They are generally experimentally determined in the wind or water tunnel, and the controlled or uncontrolled motions of the craft are predicted based thereon.

The Common

Abstract Part 1 of the paper presents a study of the common characteristics of both plane symmetry and axial symmetry in the theory of elasticity; viz., the form of the stress tensor and the existence of further analogous symmetries. In Part 2, the subject deals with the possibility of the existence of further analogous symmetries which are found to be possible only in some specific cases. In particular, spherical symmetry is treated. The method of obtaining the stress function of this new symmetry and the equation which this function must satisfy also are discussed, together with the stresses expressed by means of this stress function. The paper ends with a brief review of a general solution of the stress function and an example of the application of this stress function to a given problem.
