  • A Coarse-Fine Time-to-Digital Converter (TDC) using the single time amplifier is proposed. A vernier delay line is used to overcome process dependency and the 2-stage time amplifier is designed to have high resolution by increasing the gain of the time amplifier. Single time amplifier architecture reduces the silicon area of the TDC and alleviates mismatch effect between time amplifiers. The proposed TDC is implemented in $0.18{\mu}m$ CMOS process with the supply voltage of 1.8 V. The measured results show that the resolution of the TDC is 0.73 ps with 10-bit digital output, although highend process is not applied. The single time amplifier architecture reduces 13% of chip area compared to previous work. By reducing the supply voltage, the linearity of the TDC is enhanced and the resolution is decreased to 1.45 ps.

  • We have developed Logic Design Training Kit for studying, actual training, designing of FPGA(Xillinx) or CPLD(ALTERA CPLD), the Digital Logic Device. This training kit has 12 matrix keys, RS232 port for serial communication and uses LED array. six FND(Dynamic), LCD as display part. That is standard specification for digital logic training kit. Special point of this kit is that we make two logic device trainig kit. This two logic device kit have more smaller and simple architecture because only uses one chip. That chip already includes a lot of functions that need for training kit, such as : complex logic circuit needed the two kind of logic devices, 16 way of system clock deviding function, serial communication interrupt....etc. We called that one chip is Center Bridge Chipset ; Xillinx FPGA Spartan2. User can select between using one device of FPGA or CPLD, or uses both them. Because of, Center Bridge Chipset has profitable architecture. it can work as Logic Device's networking with Master-Slave connection When using both logic devices.

  • The distributed digital control system has many shared common components, and a single fault in the system may have effects on not a single function. Not as in an analog system, the faults in a digital system usually make discrete and abrupt changes in its output, which are hard to be expected. To cope with these situations, the fault-tolerance is an inevitable property of a distributed control system. A distributed digital control system consists of many equipments, and each equipment can be implemented by many different technologies. The fault-tolerance has to be implemented depend-ing on the overall architecture and how each equipment is implemented. The paper analyzes and compares the strategies and tactics to add the fault-tolerances in a distributed digital control system, and studies how they can be combined appropriately.

  • One of the problems with the base station equipment is that there is a large difference between the replacement time of the hardware equipment such as the base station equipment and the radio access equipment, and the evolution period of the communication standard. Therefore, the base station communication platform must be flexible enough to handle the evolving communication standards after purchase. Recent research on reconfigurable communications platforms has focused on the efficient architecture of the communications platform to meet these requirements through software downloads while still using existing hardware. This paper presents a prototype of a base station communications platform based on the ETSI standard reconfigurable architecture. The communication platform presented in this paper is implemented as an ETSI standard reconfigurable architecture using a general-purpose DSP (Digital Signal Processor). In the implemented prototype, we verify the real-time feasibility of communication protocol updates through software reconfiguration.

  • In this study, the ex-formal expressions observed in space form of Korean modern architecture are distributed for characteristic analysis based on the period and type. The result of the study is certified by the work analysis and the result is as follows. Initially, due to the limited materials and influence of western brutalism, the works developed during 1960~70 tend to be plastic and contain expressionism. Around 1980's, the works tend to show forms of amusement and popularity. In 1990's the works show significance in deconstructive expression. From after 2000, ecological concept of architecture was introduced and organic expression started increasing Secondly, the ex-formal expressions are found to be in four different types. The organic expression is shown regardless of the period. In modern days, not only the physical properties of materials, but also the ecological concept is combined with the organic expression and is in increase. The plural expression started appearing after the 1980's and the sculptural diversity is enhancing with the addition of decorative factors or modification of geometrical form. The ex-construction and deconstructive expression show significance in some characteristics such as folding, inclination, and geometrical explosion. The free form and nonlinear expression tend to increase dramatically based on the development of structure technology as well as execution and introduce of the digital design technique.

  • The advent of BIM(Building Information Modeling) design process based on the digital media has brought innovation to the production and management of AEC industry. Accordingly the need for educating BIM professionals has been radically increased both in the real world practice and in academia. Some developed countries have already been studying and establishing the optimized curriculum in the academic architecture courses for BIM based education with multi_efforts using the digital media as design processing tools focused on educating architectural professionals with creativity and productivity. However in the domestic education systems, it is hardly found that researches and curriculums deal with the BIM education in the academia. Thus the objective of this paper is to investigate the architectural design pedagogy in the advanced digital media setting in response to the urgent need for BIM education. This study focuses on developing the curriculum based on practical adaptation of BIM programs for architectural education. It aims to provide students with the basic understanding of BIM theory and the practice of BIM tools as an instrument enhancing the creativity for architectural design. Thus this study proposes an BIM curriculum for the students who first encounter the notion and knowledge of BIM during their academic years. And the education result after the application of this curriculum has been analysed through the students questionnaires before and after the lecture.

  • Even though geographical drawbacks of Netherlands, the De Stiji Movement has been acting extensively as a composite arts movement. Furthermore, because this movement has influenced on even field of architecture, Walter Gropius, who had led to establish the modern architecture at that time, was not also able to be excluded from the influence of De Stiji movement. As a result, his works after 1922 when De Stijl movement had been acting vividly, shows a part of De Stijl style and definitely has a difference via-a-via early of his works. Therefore, this study in this point of view is on the purpose of how De Stijl Movement influenced on Gropius' works as the ideology of place and concepts in the period of both De Stijl Movement and Modern architecture style were being formed together. Especially, this study will analyze Dessau Bauhaus Building, which is the most influenced by De Stijl Style in Gropius' works, into the way of how De Stijl. was embodied to this building.
