The post-war period has witnessed the emergence of new towns in a number of countries in Southeast Asia. The new town development in Malaysia started with Petaling Jaya (PJ) as a satellite town in 1953 to accommodate the rapid growing population of Kuala Lumpur (KL). Shah Alam (SA), Subang Jaya (SJ) are all located in the Klang Valley and act as an important social and economic development hub in the nation. New towns have been designed in accordance with the British town planning principles, which were based on the model of a modern ideal city. They constituted a new regional character because they were developed taking into consideration factors such as local technologies as well as site and, climatic conditions. The initial goal of the new town construction and planning, which focused basically on resettling squatters, was later changed to focus on the improvement of the quality of living. This phenomenon was related to the emergence of the middle class, which had grown rapidly ever since. With the public agencies, the private sectors have played an important role in providing viable and sustainable human units of settlement that address the new design issues of new town planning. The goal of this study is to identify the identity of the recent new town planning principles of Malaysia, how they were developed over time and how they were regionalized and transformed in a cultural and regional context. For the analysis, we chose 3 new towns which are located in Klang Valley and which are representative recent projects of two major housing development companies in Malaysia. To identify the planning principles, we analyzed these projects in the viewpoint of the urban space, street system, and housing blocks and units.

The terminology management is absolutely necessary for maintaining the efficiency of thesaurus. This is because the creating, differentiating, disappearing, and other processes of the descriptor become accomplished dynamically, making effective management of thesaurus a very difficult task. Therefore, a device is required for accomplishing methods to construct and maintain the thesaurus. This study proposes the methods to construct the thesaurus management using the basic elements of a topic map which are topic, occurrence, and association. Second, the study proposes the methods to represent the basic and specific instances using the systematic mapping algorithm and merging algorithm. Also, using a hub document as a standard, this study gives the methods to expand and subsitute the descriptors using the topic type. The new method applying fixed concept for double layer management on terms is developed, too. The purpose of this method is to fix the conceptual term which represents independent concept of time and space, and to select the descriptor freely by external information circumstance.

France is known to be making particular efforts to maintain its traditional urban architectural culture by diverse measures including the implementation of urban policies. However, France is facing up to the need to pursue modern urbanization in keeping with the requirements of the current times. Thus, this paper examines with what priority France is attempting to reflect in its current urban policies its determination to retain its urban architectural tradition and to recreate its capital city of Paris as a future European hub city. To that end, the paper first seeks to analyze Paris' policies for urban architecture from diachronic perspectives in a bid to determine Paris' urban architectural culture. Second, the study attempts to examine within the purview of the paradigm of contemporary urban architectural designs how Paris is pursuing the two conflicting purposes of the preservation of tradition and modern urbanization through the Paris Local Urbanization Plan (or Plan Local d'Urbanisme [PLU]). First, the findings indicate that Paris is applying the principle of a sustainable development plan in all fields of environment, economy and society. In terms of environmental sustainability, Paris is trying to improve the life quality of its citizens through the establishment of efficient mass transportation systems and the expansion of its green belt areas. In terms of social sustainability, Paris is implementing policies to ensure social diversity through housing policies. Also, in terms of economic sustainability, Paris is trying to expand employment and bolster its urban functions by conserving commercial activities and developing peripheral urban areas. Second, the findings indicate that Paris' policy of recovering its traditions takes priority over that of creating a sustainable city.

Baku, the capital of Azerbaijan, has seen a boom in construction in recent years. The old Baku city has been rapidly transforming into a new hub of high-rise buildings and lively cultural centers hosting the Euro Vision Song Contest in 2012 and European Games in 2015. A major population shift to Baku from its suburbs and the countryside has resulted in the doubling of Baku's population in the 4 years between 2009 and 2013. As of January 2013, Baku's population reached four million people, 43% of the citizens in Azerbaijan according to The State Statistical Committee of Azerbaijan. With this trend, the city needs more high-rise buildings to accommodate rapidly increasing demands for more housing and business space. Until the Azerbaijan Seismic Building Code was published in 2010 and became effective, many different seismic criteria, in terms of building codes and seismic intensities, were used for all new high-rise projects in Baku. Some designers used the SNIP (Russian) code with seismic level 9 or level 8 with 1 point penalty. Others used the Turkish code with Seismic Zone 1, UBC 97 with Zone 2 through 4, or IBC with Sa = 0.75 g through 1.0 g. The seismic intensity is now clarified with the Azerbaijan Seismic Building Code. However, the Azerbaijan Seismic Building Code is appropriate for low-rise buildings applications but may be inappropriate for high-rise project applications. This is because the code-defined response spectrum yields unrealistically conservative seismic forces for high-rise buildings with long periods, as compared to those determined by other internationally accepted building codes. This paper provides observations and recommendations for code-based seismic load assessment of high-rise buildings in the Baku area.

The free vibration of a spinning flexible disk-spindle system supported by hydro dynamic bearings (HDB) in an HDD is analyzed by FEM. The spinning flexible disk is described using Kirchhoff plate theory and von Karman non-linear strain, and its rigid body motion is also considered. It is discretized by annular sector element. The rotating spindle which includes the clamp, hub, permanent magnet and yoke, is modeled by Timoshenko beam including the gyroscopic effect. The flexible supporting structure with a complex shape which includes stator core, housing, base plate, sleeve and thrust pad is modeled by using a 4-node tetrahedron element with rotational degrees of freedom to satisfy the geometric compatibility. The dynamic coefficients of HDB are calculated from the HDB analysis program, which solves the perturbed Reynolds equation using FEM. Introducing the virtual nodes and the rigid link constraints defined in the center of HDB, beam elements of the shaft are connected to the solid elements of the sleeve and thrust pad through the spring and damper element. The global matrix equation obtained by assembling the finite element equations of each substructure is transformed to the state-space matrix-vector equation, and the associated eigen value problem is solved by using the restarted Arnoldi iteration method. The validity of this research is verified by comparing the numerical results of the natural frequencies with the experimental ones. Also the effect of supporting structures to the natural modes of the total HDD system is rigorously analyzed.

This paper presents a finite element method to analyze the free and forced vibration of a hard disk drive (HDD) considering the flexibility of a spinning disk-spindle with fluid dynamic bearings (FDBs), an actuator with pivot bearings, an air bearing between head-disk interface and the base with complicated geometry. Finite element equation of each component is consistently derived with the satisfaction of the geometric compatibility of the internal boundary between each component. The spinning disk, hub and FDBs are modeled by annular sector elements, beam elements and stiffness and damping elements, respectively. The actuator am, E-block, suspension and base plate are modeled by tetrahedral elements. The pivot bearing in the actuator and the air bearing between head-disk interfaces are modeled by the stiffness element with five degrees of freedom and the axial stiffness, respectively. A global matrix equation obtained by assembling the finite element equations of each substructure is transformed to a state-space matrix-vector equation, and both damped natural frequencies and modal damping ratios are calculated by solving the associated eigenvalue problem with the restarted Arnoldi iteration method. Modal and shock testing are performed to show that the proposed method well predicts the vibration characteristics of a HDD.

An optimization procedure for the design of a ventilation axial-flow fan is presented in this paper. Flow analyses of the preliminary fan are performed by solving three-dimensional Reynolds-averaged Navier-Stokes equations via a finite-volume solver with the shear-stress transport turbulence model as a turbulence closure. Three variables, the hub-to-tip ratio and the stagger angles at the mid and tip spans, are selected for the optimization. The Latin-hypercube sampling method as a design-of-experiments technique is used to generate twenty-five design points within the design space. and the weighted average surrogate models, WTA1, WTA2, and WTA3, are applied for find optimal designs. The results show that the efficiency is considerably enhanced.
