  • This study is intended to suggest methodologies in theory that is dedicated to improve existing features in BlM tool sets and introduce a new horizon for developing new features in the future so that more functionality can be provided to the work process of architect. To be more utilized of BlM tool sets in a useful way, it is important to make sure to program a calculation method used in the design process which is based on the information provided by architect, such as design item with detailed process and transformed parametric information on warranty data. Finding pros and cons in the usability from the well-known 3D modeling applications and taking highly usable UI features from the existing applications, and using a common wording were carried out. Design architect identifies reusable parametric information and then finds an algorithm between each items so that BlM tool sets can contribute to design field in the future. Therefore, the formula has been developed for the items considering business aspects and architecturing size in the preliminary-design, and design aspects in the schematic design with idendifying inputs and outputs that is necessary to become fixed factors.

  • Recently, as the heterogeneous network (HetNet) has been deployed widely to support various kinds of Radio Access Networks(RANs) with a combination of Macro, Pico, and/or Femto cells, research and standardization efforts have been very active regarding the concept of Licensed Shared Access (LSA) for supporting spectrum sharing. In order for a mobile device to efficiently support the spectrum sharing, the mobile device shall be reconfigurable, meaning that its radio application code has to be adaptively changed in accordance with the hopping of desired spectral band. Especially, Working Group 2 (WG2) of Technical Committee (TC) Reconfigurable Radio System (RRS) of European Telecommunications Standards Institute (ETSI) has been a main driving force for developing standard architecture for Multi-mode Mobile Device (MD) that can be applied to the LSA system. In this paper, we introduce the Multi-mode MD architecture for supporting LSA-based spectrum sharing. An implementation of a test-bed of Multi-mode MD is presented in order to verify the feasibility of the standard MD architecture for the purpose of LSA-based spectrum sharing through various experimental tests.

  • This paper presents an efficient demapper architecture based soft-decision using the phase-section for Digital Video Broadcasting via satellite, Second Generation (DVB-S2). To achieve the satisfactory performance under a very low SNR conditions with the efficient hardware resource utilization, we propose a simple soft-decision demapper architecture using comparators to compare the phase of symbols and memories. The proposed architecture can decrease about 81% of the hardware resource, satisfying the BER requirements of DVB-S2. It has been thoroughly verified with an FPGA board and R&S(R)SFU (Rohde&Schwarz SFU-K108) broadcaast test equipment.

  • This paper presents new DSP (Digital Signal Processor) instructions and their hardware architecture for high-speed FFT. the instructions perform new operation flows, which are different from the MAC (Multiply and Accumulate) operation on which existing DSP chips heavily depend. The proposed DPU (Data Processing Unit) supporting the instructions shows two times faster than existing DSP chips for FFT. The architecture has been modeled by the Verilog HDL and logic synthesis has been performed using the 0.35 ${\mu}m$ standard cell library. The maximum operating clock frequency is about 144.5 MHz.

  • Dependability-critical systems, such as digital instrumentation and control systems in nuclear power plants, necessitate engineering techniques and tools to provide assurances of their safety and reliability. Determining system reliability at the architectural design phase is important since it may guide design decisions and provide crucial information for trade-off analysis and estimating system cost. Despite this, reliability and system engineering remain separate disciplines and engineering processes by which the dependability analysis results may not represent the designed system. In this article we provide an overview and application of our approach to build architecture-based, dynamic system models for dependability-critical systems and then automatically generate dynamic fault trees (DFT) for comprehensive, tool-supported reliability analysis. Specifically, we use the Architectural Analysis and Design Language (AADL) to model the structural, behavioral and failure aspects of the system in a composite architecture model. From the AADL model, we seek to derive the DFT(s) and use Galileo's automated reliability analyses to estimate system reliability. This approach alleviates the dependability engineering - systems engineering knowledge expertise gap, integrates the dependability and system engineering design and development processes and enables a more formal, automated and consistent DFT construction. We illustrate this work using an example based on a dynamic digital feed-water control system for a nuclear reactor.

Research methods and settings of the range to study on the Extension of User Experience are as follows: First, establish digital space's characteristics comparing digital space at the structural change-points in modern society. Second, experience's approch way through the digital media in the contemporary space. And understand the concept about a variety of User Experience. Third. to classify the elements of access control for the user experience. Experience is being expanded through the generation process. Fourth, investigate analysis of the case studies, focused on the architecture and space design_Media installations that appear in the city park, the city's landmark buildings facade, the building facade by offering commercially applied for brand marketing_ announced through the media recently. Also, it is to look at the physical elements through digital media and to analyze the applicability of the public space.

  • Lighting simulation is becoming increasingly more important as a method for design and evaluation. There is a wide range of packages that provide the accuracy and the usability in lighting simulation. Relux developed by Relux Informatik AG, Switzerland, Relux offers users innovative and high-performance light planning software with open interfaces and simultaneous access to the latest product data from luminaire and lamp manufacturers. The goals of this report is to explore some of the lighting simulation issues relating to Relux. It is hoped that it will provide some background information that will enable a designer and engineer to make some informed judgements on the potential of the current state-of-the-art in computer prediction of lighting in buildings and how this may be used to assist in building design.

  • The purpose of this study is to propose an integrated curriculum for architectural studio in university to implement BIM process. There have been several BIM education methods occurred in school, but most of them are not successive courses but independent events. To integrate BIM into architectural curriculum successfully, it needs continuous and gradual approach. This study is proceeded by the research of precedent and analysis of key factors in foreign school program. Also fundamental objectives of the current domestic architectural curriculum are categorized to match the BIM process and functionality. As a result of this study, the new architectural design education process integrated with milestone of BIM tool is proposed.
