  • The atomizing characteristics in a spray injected from a twin fluid atomization nozzle have been investigated. The Sauter mean diameters as mean diameter are compared with wavelength calculated from the instability theory. The Sauter mean diameter are measured by the Fraunhofer diffraction theory using the Malvern particle sizer. The wavelength is calculated using the mean relative velocity instead of the exit relative velocity of nozzle. Also shadowgraphy technique is used to visualize atomization. This paper gives a possibility that the mean diameter can be predicted with the wavelength obtained by the simple instability theory.

  • This paper presents assessment of possibility on the human risk for the electromagnetic field of unbalanced two coupled three-phase transmission line using fuzzy theory. Three phase load flow program was developed which employed a Newton-Raphson method as a tool to analyze system unbalanced. This research presents a method of handling two coupled three phase transmission system unbalance analysis and unbalanced power demand as a function of voltages. As the results of case study, in case of 345[kV] T/L, the electric field intensity was 10.9540[kV/m], magnetic field intensity was 0.2567[G] in severest case. The results showed that the membership of a proposition fuzzy '10.9540 [kV/m] is hazardous' is 0.6349. As the analytic results using the fuzzy qualifier term, the membership in case of very false is 0.1379 and fairly false is 0.6124, respectively. In assessment of fuzzy measure possibility for the electromagnetic field, this paper used probability of fuzzy arid measure of fuzziness technique.

  • In relation to spatial expression, the remediation theory of Jay David Bolter & Richard Grusin shows a sufficient possibility of providing extended idea and experience through the space of critical representation. The remediation theory discussed in the scope of new media says about the existence method and the development process of media through immersion into media and awakening, and one attribute of remediation which aims at the extension of another realistic experience and recognition through various media, contains common denominators which display diversity and complexity of installation space, and use the audience as expression elements. Therefore, this study aims to apply the remediation theory in order to interpret space using more diverse and multisensory expression methods. For achieving this purpose, this study found the connection among characteristics of hypermediacy which is an axis of installation and remediation theory, and analyzed diverse cases regarding installation space and characteristics of hypermediacy, depending on external aspects of form and expression and internal aspects of experience and cognition. The method of hypermediation expression in installation space converts the recognition about the basic custom of new experience, space and representation. This means that the logic of remediation could approach space by leading to more extended form and recognition. In conclusion, the characteristics of space and the possibility of extended expression revealed in the relationship between installation space and hypermediacy logic would provide another developmental significance for research on space design.

  • In this paper, we study the Carbon/Glass hybrid laminated composite plates, where the buckling behavior is examined using an accurate and simple refined higher order shear deformation theory. This theory takes account the shear effect, where shear deformation and shear stresses will be considered in determination of critical buckling load under different boundary conditions. The most interesting feature of this new kind of hybrid laminated composite plates is that the possibility of varying components percentages, which allows us for a variety of plates with different materials combinations in order to overcome the most difficult obstacles faced in traditional laminated composite plates like (cost and strength). Numerical results of the present study are compared with three-dimensional elasticity solutions and results of the first-order and the other higher-order theories issue from the literature. It can be concluded that the proposed theory is accurate and simple in solving the buckling behavior of hybrid laminated composite plates and allows to industrials the possibility to adjust the component of this new kind of plates in the most efficient way (reducing time and cost) according to their specific needs.

  • The concept and spatial composition of office have endlessly changed according to social trend. And according to social change, members of office, namely, concept of organization has been changed. Presently, our society finds and needs appearance of office suitable for our society. According to a concept of ecological environment and a concept laying stress on human, various trials have been performed but still, stress of salaried men is treated as social issue. By having connection between psychological healing theory of Max $L{\ddot{\bar{u}}}scher$ and spatial expression elements (content : refuge, self-esteem : prospect, confidence : flow, liberty : void) as a theory, we discussed possibility of aesthetic office landscape could be developed to a type of office which could control emotion that can be a cause of stress and we intended to examine limitation and possibility through case analysis.

  • The purpose of this study was to get a possibility of maintenance architecture, which present instead of contemporary architecture through interrelation between Organic architecture and Gaia theory. Through this study to fine a interrelation part between Organic architecture and Gaia Theory as general case, and through the Gaia theory, Organic architecture being progress as new design experiment exposition. After modern time, we can have presentation of main subject which corresponds to mechanical rationalism and rising Organic architecture from Organic Holism. Organic architecture is get close to biological or ecological access to nature and environment so from and inner order could apply to architecture after that better circumstances and maintenance(sustain architecture) development could possible, although the point became more importance. In this point, Jim E. Lovelock's Gagia theory which try to proscript relationship(element of enviroment) of earth, this is pretty big deal and we can find a connection with Organic architecture in the theory.

  • This essay addresses the role of environmental aesthetics in landscape architecture : how can environmental aesthetics enrich landscape architectural theory and practice\ulcorner It begins by criticizing the predominant notions toward theory : theory as an instrumental design method, theoretical vacuum in modernism of landscape architecture, and the intimate relation of theory and practice in 18th-century England. It suggests that the expulsion of theory in landscape architectural academics and profession is nothing but an inappropriate bias. In the second place, the essay explores a remaining question : why environmental aesthetics is a part of landscape architectural theory\ulcorner I would argue that environmental aesthetics can transcend the man-nature(subject-object) dichotomy, one of heritages of Western modernity project. Here, landscape architecture meets environmental aesthetics, and both can intermediate between theory and practice. For landscape architecture is (and ought to be) a device of embodied communication, creating symbolic settings wherein an interconnection of man and nature can occur. Finally, this essay examines the aesthetics of engagement that Arnold Berleant claimed recently. This theory of aesthetic experience has a possibility of making corrections some improper conventions in landscape architectural creation and appreciation : disinterested contemplation, visual-orientedness, decoration-denteredness, and so forth. I would conclude that environmental aesthetics can be a significant theory which can correct misconceptions in landscape design and appreciation and, further, can lead contemporary practice. As the great mediator between man and nature, between theory and practice, environmental aesthetics has a profound role to play in the realm of landscape architecture, and vice versa.
