  • Protocol conformance testing consists of procedures to observe an output and to check a transition state of the Implementation Under Test considered as a black box by applying an input. There are several methods to check the transition state such as Unique Input/Output(UIO) sequence. Distinguishing Sequence(DS) and Characterization Set(CS). Particularly, as a test method for a state having no UIO sequence, Partial UIO sequence method can be considered. In this paper, three properties which can be found among Partial UIO sequence and a modified algorithm using these properties are suggested.

  • A variety of different metrics has been introduced to measure the similarity of two given sequences. These widely used metrics are ranging from spell correctors and categorizers to new sequence mining applications. Different metrics consider different aspects of sequences, but the essence of any sequence is extracted from the ordering of its elements. In this paper, we propose a novel sequence similarity measure that is based on all ordered pairs of one sequence and where a Hasse diagram is built in the other sequence. In contrast with existing approaches, the idea behind the proposed sequence similarity metric is to extract all ordering features to capture sequence properties. We designed a clustering problem to evaluate our sequence similarity metric. Experimental results showed the superiority of our proposed sequence similarity metric in maximizing the purity of clustering compared to metrics such as d2, Smith-Waterman, Levenshtein, and Needleman-Wunsch. The limitation of those methods originates from some neglected sequence features, which are considered in our proposed sequence similarity metric.

  • The Fibonacci sequence is a sequence of numbers that has been studied for hundreds of years. In this paper, we introduce the modified k-Fibonacci-like sequence and prove Binet's formula for this sequence and then use it to introduce and prove the Catalan, Cassini, and d'Ocagne identities for the modified k-Fibonacci-like sequence. Also, the ordinary generating function of this sequence is stated.

  • Pan, Shen and Woo [8] introduced the concept of the G-sequence of a map. We introduce the G'-sequence of a map, which is a dual concept of the G-sequence of a map. We obtain some sufficient conditions for the all sets in the G'-sequence of a map are groups, and for the exact G'-sequence of a map.

  • We find some conditions under which G(f)-sequence of a CW-pair (X, A) is exact. And we also introduce a G(f)-sequence for a CW-triple (X, A, B) and examine when the sequence is exact.

  • 본 논문에서는 Multi-layer sequence-to-sequence 구조를 이용해 한국어 대화 시스템을 개발하였다. sequence-to-sequence는 RNN 혹은 그 변형 네트워크에 데이터를 입력하고, 입력이 완료된 후의 은닉층의 embedding에 기반해 출력열을 생성한다. 우리는 sequence-to-sequence로 입력된 발화에 대해 출력 발화를 내어주는 대화 모델을 학습하였고, 그 성능을 측정하였다. RNN에 대해서는 약 80만 발화를, MTRNN에 대해서는 5만 발화를 학습하고 평가하였다. 모델의 결과로 나타난 발화들을 정리하고 분석하였다.

  • When we design the control system used Programmable Logic Controller(PLC), we program the main algorithm by Ladder Diagram(LD) among the standard language. We can substitute the select sequence function by the unique sequence. We can implement this function by the delay time. Therefore this thesis show the select sequence function by the unique sequence and we confirmed its feasibility through actual example.
