Ahmed W. Al Zand, Wan Hamidon Wan Badaruzzaman, Azrul A. Mutalib and Salam Jasim Hilo
The behaviour of Concrete Filled Steel Tube (CFST) beam strengthened with Carbon Fibre Reinforced Polymer (CFRP) sheet was investigated numerically in this paper. Nonlinear analysis using ABAQUS Finite Element (FE) software to assess the behaviour of square and circular CFST beams wrapped from bottom side with U shaped of CFRP sheet using different length and multi layers. The FE models were verified accurately through successful comparison with existing experimental study done by others. The results obtained from the study show that various lengths and multiple layers of CFRP sheets directly affect the ultimate moment capacity of CFST beams, where the ultimate moment capacity of the CFST beams was improved by increasing the layers of CFRP sheets specifically for beams wrapped along 75% or more of their length. Meanwhile, CFRP delamination failure has been observed for beams wrapped along 50% of their length, where delamination failure occurred earlier with an increasing number of CFRP layers. Moreover, by increasing the wrapping length of CFRP sheet to more than 75% of the beams length did not lead to further improvement in the beams moment capacity for each specific number of CFRP layers.
3. FORCED VIBRATION OF DAM AND RESERVOIR USING SBFEM
Determination of the hydrodynamic pressure acting on dams during earthquake has been of high interest in design steps of these structures. An efficient method for the analysis of forced vibration of the dam and reservoir in different modes of the dams motion and deformation has been presented which, could be easily extended to study fluid structure interaction. The SBFEM (Scaled Boundary Finite Element Method) is utilized to model the far field sub domain while the FEM (Finite Element Method) is used to model the near field sub domain of the reservoir. Although a simple geometry of boundary conditions has been chosen, all the required necessities to extend the method to a practical case are implemented.

6. POWER QUALITY IMPROVEMENT IN Z SOURCE INVERTER FED WIND POWER GENERATION SYSTEM
This paper deals with power quality improvement of a Z source inverter fed wind power generation system, using hybrid active power filter. The Z source inverter is used as power electronic interface for voltage and frequency control. However, it introduces higher order harmonics into the system, the use of non linear load also has inherent problem of poor power quality. To overcome the problems of harmonics and reactive power hybrid active power filter is introduced between system and load. The proposed wind power generation system is modeled in MATLAB / Simulink environment. Improved performance of the system after inclusion of hybrid active power filter is demonstrated through comparison on various indices like THD, reactive power compensation, power factor etc.

Lintang Suminar, Eddi Basuki Kurniawan, Fadly Usman
Yogyakarta is a tourism city with increasing number of tourists. This result to the area surrounds points of interest turning into business and trade area. The growing business and trade sector induces the tendency to use signage for advertisement. The problem is, the existence of that many signages somehow have covered up the face of Yogyakarta as a cultural heritage. There are so many occurrences of misused signage, varied from misplaced signage to installing unauthorized signage. Furthermore, another problem occurs from the visual aspect of the city, because signage instalment affects the aesthetic of the street corridors. Therefore, a research in field of organizing signage must be conducted based on visual aspect. This research is aimed to create an organized design of signage that is appropriate according to visual aspects (colour, form, line, texture, and scale). This research is also using descriptive method in the form of policy analysis and evaluative analysis through Visual Impact Assessment. The result of this study is formed as how much the signage impacts visual aspect and then developed into an input for creating signage design and adapted to the policy.

Carbon membranes have been studied in the last few years as a promising candidate for energy efficient gas separation processes in replacing the traditional membranes such as polymeric membranes. Carbon tubular membrane can be achieved by carbonizing polymeric tubular membrane under different process parameter. Carbonization is the most important step in the fabrication of carbon membrane and can be recognized as the heart of the carbon membrane production. The preparation and characterization of carbon membranes originated from Matrimid were studied. Matrimid based carbon tubular membrane will be fabricates and characterize in terms of its gas permeation properties. The carbonization temperature during the carbon membrane fabrication was studied. The polymer solution was coated on the surface of tubular ceramic tubes by using dip coating method. The polymer tubular membrane was then carbonized under Argon atmosphere at different carbonization temperature, 600, 750, and 850oC. Pure gas permeation tests were performed using CH4 and CO2 at room temperature with pressure 8 bars. Based on the results, the highest CO2/CH4 selectivity of 87.30 was obtained for carbon membrane prepared at 850oC.
10. ARCHITECTURE, MUSIC AND PATTERN RECOGNITION THE CASE OF ANDALUSIAN ARCHITECTURE
The aim of this ongoing research project is to reach a pattern recognition process (design system) that can turn architecture to music, and turn music to architecture. In both operations, style and character will be an essential issue in the design of this process system. Based on the artistic relationship between architecture and music, we shall try to settle a mechanism for a pattern recognition audio visual system that can that can turn a certain style of architecture to a collection of melodies that truly reflects the character of that architecture. This system can also perform the inverted process that is turning a certain musical style to a collection of shapes and forms. In this regard it is important to point out to the inter relationship between the architectural design process and writing a musical note. A musician composing a melody works from above, that is from the whole to the parts. A composer does not usually put notes together in order to get some melody he envisages the character of a melody in a statu nascendi and proceeds from above as he tries to concretize it in all its part. In this respect, the articulation of the whole and the important junctures of the parts, the beginning(s), or the end(s), the composer accepted the attitude of his contemporaries, and could therefore integrate principles of architecture such as the golden section and the Pythagorean Theorem, along with principles of acoustic harmony. The melody steps of these musical golden sections (time space intervals of varying scales) can follow the rules of the Pythagorean Theorem. Originality in expression does not depend on invention of new words nor originality in poetry on invention of new measures nor in painting on invention of new colours, or new modes of using them. That means that innovation and creativity is a matter of "relationships". In architecture relationships exist in two ways, in the environment itself, and in the individual's ability to understand and relate to them. They exist at a real, concrete level where the individual is aware of them through his senses, perception, hearing, touching, etc. And the also exist at an abstract or conceptual level in the actual object. They cannot be seen or heard even though the can be described. At the end we are referring to "linguistics" as a platform that can consist architecture and music i.e. a perceptual or surface structure and a conceptual or deep structure that combines both architecture and music. Architecture and music share the unification of three realms, conceptual, objectual and perceptual. In the historical writings of ikhwan al safa, (The Brethren of Sincerity Muslim philosophers in Basra, Iraq, in the 10th century), the relationship between arts, architecture, music, astronomy, mathematics and chemistry was clearly mentioned. In this paper we had chosen Andalusian Architecture as a part of Islamic Architecture that existed in Spain (AD 711 1492). Also there is a significant retrieving and re composing for Andalusian music prepared by Al Rahbaniya in Lebanon in seventies of the 20th century, also Andalusian music is still played in Morocco, Algeria and Tunisia.
11. CONSTRUCTION OF DESIGN & DESIGN OF CONSTRUCTION
Nowadays, we are working in a stimulating scenario where the new digital technologies and the traditional design process in Architecture are definitively mixed together. We know that majority of mistakes in the phase of construction comes from the design phase and this trend looks often to come from a base concept aimed to separate, dramatically, the design activity from the construction activity. The most negative effects were detected in terms of increasing costs and of decreasing of the quality of the buildings. The new computational methodologies can enable us to obtain significant benefits in reducing the gap between designing and building. The new parametric approaches can help to highlight the centrality of the constructive detail. The concept of parameter is, at the same time, logical element and material element, therefore its nature is related to the theory and also to the practice of the Architecture. If we think to the importance of the executive detail, the parametric approach looks like the link between the "bit" and the brick. It is necessary designing the building, according its constructive logic, that is possible only trying to develop a biunique link between the two phases of the process that must be conceived as only one. To think via parametric the constructive details, means knowing that any existing design complexity can be lead back to an original constructive element, this dynamic discloses the sense of the complexity. I think that the digital fabrication represents the first real “bridge” between design and construction, because transforms a digital component in real component. The new technical and cognitive paradigms can be an efficient contribution in order to define a theoretical and practical vision in order to understand "the design of the construction" and "the construction of the design" as one. The next step of that current research will be how to move our vision from the “Architecture as ontology” to the “Architecture as taxonomy”.
12. A PEDESTRIAN WAYS RE ARRANGEMENT BASED ON STAKEHOLDER PERCEPTION IN ORDER TO EMPHASIZED USERS WALKING EXPERIENCE (CASE STUDY ENGGAL, BANDAR LAMPUNG CITY, INDONESIA)
Zenia F Sarasawati, Imma Widyawati Agustin, Johannes Parlindungan
Enggal area is a public space which consist open space, sports stadium, offices, settlement, and commercial buildings. Located in the downtown of Bandar Lampung City, Enggal is an area with high traffic of pedestrian. This research is conducted to formulate a design concept of pedetrian ways which accentuate to emphasized pedestrians walking experience when walking and also increasing society interest to walk more. To emphasised pedestrians walking experience, it consist of three main principle designs of pedestrian ways which is safety, convenience and pleasure. Collaborating with pedestrians characteristic analysis, behaviour setting analysis, pedestrian ways geometric analysis, analytical hierarchy process and multi criteria analysis which is consist of experts and the users, Enggal areas diversity index of space shown 0,86 means the research area has a high democratic value which consist of vary elements of user. Pedestrians behaviour in synomorphic and milleu captured limited walking space of pedestrians. Pedestrians who walk with their spouse don't able to walk abreast and needs change their position into parallel when they are crossing pedestrian ways with other pedestrians. Pedestrians behaviour setting shows they are in inconvenience level as a pedestrian. They need to get out from pedestrian ways to the main road in order to averse the cadgers and broken sidewalk. The concept of pedestrian ways arrangement based on stakeholder perception shows the ranking priority of every elements from safety, convenience and pleasure which is need to be prioritized such as flat and smooth pedestrian ways design, free of cadgers and the pattern of shading plants placement.
