In this paper, the comparison and analysis of PTI and IEEE data formats are conducted. and the algorithm and the developed program for data conversion between these data formats are proposed. PTI and IEEE data formats are widely used as the input data form of the software program for power systems. However, they are composed of different formation with each other. So, it is necessary to convert between two formats in order to use more programs with different input data format. Numerical results of the power flow calculation of the test system show that developed program is effective and useful.

In this paper, we develop a descriptor based on binary ECG conversion system that supports the conversion of a binary ECG format into XML-based HL7 aECG for the interoperability of ECG. HL7 aECG is a XML based standard for interoperability of ECG waveform. For the conversion of variety of ECG formats, we propose a binary ECG description mechanism. In order to describe binary ECG more efficiently, we develop a XML-based Binary ECG Description (BED) Language. One of the powerful features of using the XML-based ECG Description mechanism is that ECG data can read from various formats without the modification of source code of conversion system, and consequently it reduces conversion system maintenance costs.

ATSC (Advanced Television System Committee)에서는 18가지의 DTV (Digital Television)를 위한 동영상 포맷들을 제정하였다. ATSC 포맷들은 스캔 포맷, 크기 포맷, 프레임율 포맷 등의 적당한 조합들이다. 효과적인 MPEG-2 트랜스코딩을 위해서는 이런 포맷들 간의 변환도 지원할 수 있어야 한다. 여러 포맷 변환들 중에서 특히 스캔 포맷 변환은 프레임율과 크기 변화가 함께 일어나기 때문에 상대적으로 구현하기가 힘들다. 스캔포맷 변환으로 픽쳐 타입도 함께 변하기 때문에 트랜스코더의 움직임 추정부 (motion estimation; ME)에 상당한 연산량 부담을 주게 된다. 이런 문제를 해결하기 위해 본 논문은 스캔포맷 변환을 지원하는 MPEG-2 동영상 트랜스코딩을 위한 고속 움직임 추정 알고리즘을 제안한다. 먼저, 트랜스코더의 수신단은 입력 비트열로부터 재 부호화(re-encoding)에 적합한 후보 움직임 벡터들을 추출한다. 그런 다음. 가중치 중간값 선택기(weighted median selector)를 이용하여, 여러 후보 움직임 벡터들 중에서 최적의 움직임 벡터를 선택한다. 모의 실험 결과는 제안한 움직임 추정 알고리즘이 전역 탐색 기법(Full Search Algorithm: FSA)에 비해 현저하게 적은 연산량을 가지면서, FSA와 거의 동일한 PSNR 성능을 가짐을 증명한다.

The purpose of format conversion is to convert a wide range of personal computer video formats into a target format. Circuits for the conversion have been developed by means of interpolation techniques, such as zero-order interpolation, bilinear interpolation, and bisigmoidal interpolation. This paper proposes a scan converter using cubic splines. The converter was modeled in VHDL on Max+PlusII and implemented with an FPGA chip. The circuit gives much better conversion performance than a scan converter with zero-order or linear interpolation.

Circuits for the conversion have been developed by means of interpolation techniques, such as zero-order interpolation, bilinear interpolation, and bisigmoidal interpolation. This paper proposes a scan converter using cubic splines. The converter was modeled in VHDL, simulated on Max+plus Ⅱ , and implemented with an FPGA chip. The circuit gives much better conversion performance than a scan converter with zero-order or linear interpolation techniques according to simulation results and implementation.

메타데이터 개념에 관한 혼란을 살펴보고 개념 변화의 이유에 대하여 알아보았다. 이종 메타데이터 포맷에 관하여 새로운 포맷의 생성 이유, 그들의 특징, 특히 MARC 포맷과 관련하여, 그리고 이들의 변환 및 통합 방법과 문제점을 배경연구로 조사하였다. 이종 메타데이터의 통합 틀로서 RDF와 메타데이터 레지스트리를 조사하고 비교하였다. 이 두 방법은 서로 경쟁적인 접근방식이 아닌 상호보완적인 관계를 가진다고 결론 내렸다.

To allow for a quick conversion of the proprietary sequence data from various sequencing platforms, sequence format conversion toolkits are required that can be easily integrated into workflow systems. In this respect, a format conversion tool, as well as quality conversion tool would be the minimum requirements to integrate reads from different platforms. We have developed the Pyrus NGS Sequencing Format Converter, a simple software toolkit which allows to convert three kinds of Next Generation Sequencing reads, into commonly used fasta or fastq formats. The converter modules are all implemented, uniformly, in Java GUI modules that can be integrated in software applications for displaying the data content in the same format.

General-purpose MPEG-2 video transcoders must be able to achieve any conversion between 18 ATSC (Advanced television system committee) video formats for DTV (digital television), e.g., scan format, size format, and frame rate format conversion. Especially, scan format conversion is hard to implement because frame rate and size format conversion often happen together. This paper proposes a fast motion estimation(ME) algorithm for MPEG-2 video transcoding supporting scan format conversion. Firstly, we extract and compose a set of candidate motion vectors (MV's) from the input bit-stream to comply with the re-encoding format. Secondly, the best MV is chosen among several candidate MV's by using a weighted median selector. Simulation results show that the proposed ME algorithm reduces significantly transcoding complexity with a minor PSNR degradation.
