Art has always been a witness to its time. The art of our century has lived through two world war. In that time Friedensreich Hundertwasser was born to a half Jewish family in Vienna in 1928. He lived and died as a painter, architect, designer, ecologist, writer, innovator... etc. He was impressed form Gustav Klimt, who pioneered the Viennese Secession which was the Austrian expression of the Art-Nouveau mouvement and inspired by the works of Egon Schiele from an early date. His style as an architect was heavily influenced by Antonio Gaudi and some of the Jugendstil architects. Although his architectural work is comparable to Gaudi in its biomorphic forms and use of tile, but is currently renowned for his unique styling. His character as follows; First, Bold color - His use of color is bold, and he has a strong sense of which color work well together. Second, Curved line & Spiral - It's the primary shapes in his works against the tyranny of ugliness and the iron rule of its straight line. Spiral reveal as a transautomaism. Third, Harmony with nature - His work is the creator of beauty, of nature of harmony, peace of joy, against the contradictions of our post-industrial society. He represented these various characteristics in his works. Hundertwasser first achieved notoriety for his boldly-colored painting, he is more widely renowned today for his revolutionary architectural designs.

There is a shround of mystery surronnding Gaudi. In all probability, the first mist preventing us from gaining acess to his work is the intrinstic mysteriousness of all genius and, at the end of the day, of all human spirit. The situation is complicated by the well-known fact that Gaudi wished to creat an aura of silence around his persona, while, at the same time as maintaining this secretiveneness - in other words, the annihiliation of his fundamental values-gave expression and symbolisation to his moods and incerdible mental power. On a piece of land on the Muntanya Pelada, in the Barcelona district of La Salut, Eusebi G$\ddot{u}$ell Wanted to build an urbanisation inspired by the concepe of the garden city. in this he sought to return to nature, health and an escape from the insalubrous industrial city. Gaudi worked on the construction of this park between 1900 and 1914, and even moved his home there in 1906. An outstanding feature of park G$\ddot{u}$ell is the integration of architecture with nature. In other to save the natural slopes, Gaudi built viaducts from brick pillars, which he covered with stone obtained from the excavation.

In this study, finite element modeling and material property tests are performed for the finite element analysis of rubber isolator parts which support the engine and isolate the vibration. As a result of the P direction analysis of the rubber isolator parts, the static stiffness in the P direction was 44.2 kg/mm, which is well within the error of 5% as compared with the test result of 46.1 kg/mm. The static stiffness of the rubber isolator parts in the Q direction was calculated to be 7.9 kg/mm, which is comparable to the test result of 8.6 kg/mm, with an error of less than 8%. As a result of the analysis on the Z direction, the static stiffness was calculated as 57.7 kg/mm, and the test results were not available. Through this study, it is expected that the time and cost for prototype development can be reduced through nonlinear finite element analysis for rubber isolator parts.

Photoinduced electron transport process in nature such as photoelectric conversion and long-range electron transfer in photosynthetic organisms are known to occur not only very efficiently but also unidirectionally through the functional groups of biomolecules. The basic principles in the development of new functional devices can be inspired from the biological systems such as molecular recognition, electron transfer chain, or photosynthetic reaction center. By mimicking the organization of the biological system, molecular electronic devices can be realized $artificially^{1)}$. The nano-fabrication technology of biomolecules was applied to the development of nano-protein chip for simultaneously analyzing many kinds of proteins as a rapid tool for proteome research. The results showed that the self-assembled protein layer had an influence on the sensitivity of the fabricated bio-surface to the target molecules, which would give us a way to fabricate the nano-protein chip with high sensitivity. The results implicate that the biosurface fabrication using self-assembled protein molecules could be successfully applied to the construction of nanoscale bio-photodiode and nano-protein chip based on electrical detection.

Architecture is a shelter for society whose social pattern requires a specific form to accord with its material and spiritual needs. Providing a truly acceptable architecture requires our deeper understanding of cultural tradition - mythic values - not only because myth is an interpreted and configured form of 'thing' through man's second nature, such as his subjective and objective consciousness -'self-revelation of the absolute'- but also because, in the world of mythical imagination, a fragment of substantial reality -'thing'- becomes an equivalent mode to the signification, and emerges as 'its independent spiritual form' and 'the characteristic force of the logos.' In this sense, myth of place and myth behind tectonic form are the most essential sources for comprehending people's relationship to the world of inner and conscious experience. The recent efforts of modern architects to achieve cultural continuity should begin with re-interpretation and configulation of the myths behind describable material culture, especially artistic imagination inspired by deeper understanding of the myth of place. Myth provide artists with a creative inspiration, as they did in the past.

In this paper, alternative dynamic features for speech recognition are proposed. The goal of this work is to improve speech recognition accuracy by deriving the representation of distinctive dynamic characteristics from a speech spectrum. This work was inspired by two temporal dynamics of a speech signal. One is the highly non-stationary nature of speech, and the other is the inter-frame change of a speech spectrum. We adopt the use of a sub-frame spectrum analyzer to capture very rapid spectral changes within a speech analysis frame. In addition, we attempt to measure spectral fluctuations of a more complex manner as opposed to traditional dynamic features such as delta or double-delta. To evaluate the proposed features, speech recognition tests over smartphone environments were conducted. The experimental results show that the feature streams simply combined with the proposed features are effective for an improvement in the recognition accuracy of a hidden Markov model-based speech recognizer.

Smart manufacturing (SM) considered as a new trend of modern manufacturing helps to meet objectives associated with the productivity, quality, cost and competiveness. It is characterized by decentralized, distributed, networked compositions of autonomous systems. The model of SM is inherited from the organization of the living systems in biology and nature such as ant colony, school of fish, bee's foraging behaviors, and so on. In which, the resources of the manufacturing system are considered as biological organisms, which are autonomous entities so that the manufacturing system has the advanced characteristics inspired from biology such as self-adaptation, self-diagnosis, and self-healing. To prove this concept, a cloud machining system is considered as research object in which internet of things and cloud computing are used to integrate, organize and allocate the machining resources. Artificial life tools are used for cooperation among autonomous elements in the cloud machining system.

Compound eyes in nature present intriguing topics in physiological optics due to their unique optical scheme for imaging. For example, a bee's eye has thousands of integrated photonic units called ommatidia spherically arranged along a curvilinear surface so that each unit points in a different direction. The omni-directionally arranged ommatidium collects incident light with a narrow range of angular acceptance and independently contributes to the capability of wide field-of-view (FOV) detection. Artificial implementation of compound eyes has attracted a great deal of research interest because the wide FOV exhibits a huge potential for medical, industrial, and military applications. So far, imaging with a FOV over $90^{\circ}$ has been achieved only with fisheye lenses which rely on bulky and expensive multiple lenses and require stringent alignment. In this talk, we will discuss about the spherical 3D arrangement of the photonic structures of biologically inspired artificial compound eyes in a small form-factor to have and the functional and anatomical similiarity with natural compound eyes.

In this paper, an approach to dynamic systems control is addressed based on exploiting the potential features of the new nonlinear neural oscillator. Neural oscillators have recently enabled robots to exhibit natural dynamics using their robustness and entrainment properties. To technically accomplish this objective, the neural oscillator should be connected to the robot joints under the sensory feedback. This also requires the neural oscillator to adapt to the non-periodic nature of arbitrary input patterns. However, even in the most widely-used Matsuoka oscillator, when an unknown quasi-periodic or non-periodic signal is applied, its output signal is not always closely entrained. Therefore, current neural oscillators may not be applied to the precise control of the dynamic systems response. We illustrate the enhanced entrainment properties of the new neural oscillator by numerical simulation and show the possibility for implementation to control a variety of dynamic systems. It is verified that the oscillator can produce rhythmic signals for generating actuator signals which can be naturally modified by incorporating sensory feedback to adapt to outer circumstances.

A methodology based on Teaching Learning-Based Optimization (TLBO) algorithm is proposed for optimum design of reinforced concrete retaining walls. The objective function is to minimize total material cost including concrete and steel per unit length of the retaining walls. The requirements of the American Concrete Institute (ACI 318-05-Building code requirements for structural concrete) are considered for reinforced concrete (RC) design. During the optimization process, totally twenty-nine design constraints composed from stability, flexural moment capacity, shear strength capacity and RC design requirements such as minimum and maximum reinforcement ratio, development length of reinforcement are checked. Comparing to other nature-inspired algorithm, TLBO is a simple algorithm without parameters entered by users and self-adjusting ranges without intervention of users. In numerical examples, a retaining wall taken from the documented researches is optimized and the several effects (backfill slope angle, internal friction angle of retaining soil and surcharge load) on the optimum results are also investigated in the study. As a conclusion, TLBO based methods are feasible.
