  • The purpose of this study is to investigate the problems of the rapidly increasing voice interface and to find out what results will be obtained when the new gesture interaction is applied to the product, and to suggest the improvement method for a better user experience. Through the literature review, I have conducted a theoretical review on the changes in the product interface used in the product and the difference between them, and then conducted in-depth interviews on the 20-30 users who used voice recognition as a product trigger. As a result, it was concluded that the decline in the reliability of accuracy leads to a decrease in the preference of voice recognition interactions and an needs of appropriate interface for the functional aspect of non-relavancy in physical distance as a product trigger. This study is meaningful in that it has found a problem with the study of the product trigger interface and suggested improvement measures, and hope to be helpful in follow-up study.

  • 본 논문에서는 고속도로 전용차로에서의 운행기준을 위반한 차량을 검지하는 시스템을 제안한다. 다인승 탑승차를 별도의 차로로 통행하도록 하여 혼잡도를 해소하겠다는 정책을 시행하고 있으며, 9인승 이상 차량에 6인 이상 텁숭자를 다인승 통행차량으로 정의하며, 이러한 기준을 만족하지 않는 차량을 자동 검지하는 시스템이다. 트리거 신호 검지기와 4조의 적외선 카메라로 차량 내부 촬영하고 결과 이미지를 분석하여 자동으로 다인승 차량을 판별하여 운행 위반을 검지한다. 테스트 결과 주야간에 관계없이 80% 이상의 우수한 검지율을 나타내었다.

  • In this paper, we propose hardware prefetch mechanism with an efficient cache replacement policy by giving priority to the trigger block in which a spatial region and producing a spatial region by using the displacement field. It could be taken into account the sequence of the program since a history is based on the trigger block of history record, and it could be quickly prefetching the instructions or data address by adding a stored value to the trigger address and displacement field since a history is stored as a displacement value. Also, we proposed a method of replacing at random by the cache replacement policy from the low priority block when the cache area is full after giving priority to the trigger block. We analyzed using the memory simulator program gem5 and PARSEC benchmark to assess the performance of the hardware prefetcher. As a result, compared to the existing hardware prefecture to generate the spatial region using a bit vector, L1 data cache miss rate was reduced about 44.5% on average and an average of 26.1% of L1 instruction misses occur. In addition, IPC (Instruction Per Cycle) showed an improvement of about 23.7% on average.

  • We have constructed and studied a laser system which consists of a multiplex spark gap with 8 couples of spark gaps and a multiple parallel plate capacitor type Blumlein transmission line circuit. In this laser system, the length of the laser tube, the length of the multiplex spark gap and the total thickness of the transmission line circuit are chosen to be 520 mm. The experimental results show that one couple of spark gaps cannot give a uniform and complete lasing through the whole laser tube. All the more, a multiplex spark gap could not perform completely and synchronously. However, a multiplex spark gap in found to contribute to the increase of laser output power and the laser has performed the best when the location is three quarters of the laser tube length.

  • Since the telemetry performance using the time-delayed data dissipates the wireless channel resources, we propose the spectral efficient retransmission scheme in this paper. In the proposed scheme, the telemetry data is retransmitted based on triggered memory to improve the spectral efficiency. The proposed scheme minimizes the error caused by multipath fading, antenna pattern as well as the error caused by the flight events. In the flight simulation data, we show the proposed scheme improves the telemetry performance based on spectral efficient retransmission.

  • 최근 소프트웨어 사용자의 요구사항이 빠르게 변화하고 있으며, 그에 따른 소프트웨어 규모도 커지고 있다. 소프트웨어 개발 업체들은 적은 개발비용으로 사용자의 기대를 만족시키는 고품질의 소프트웨어를 단기간에 출시하고자 많은 노력을 기울이고 있으며, 소프트웨어 제품과 프로세스들에 대해서 제언하고 예측할 수 있는 능력을 확보하고자 노력하고 있다. SPICE 모델에 따른 소프트웨어 프로세스 개선은 소프트웨어 개발 업체의 개발 및 관리 문제점을 해결하는데 사용되고 있으나 개선을 위한 지침의 부족으로 개선 실행에 어려움을 보이고 있다. 이어 본 논문에서는 SPICE 모델에 따른 소프트웨어 프로세스 심사 결과의 개선 항목을 잠재적인 결함으로 간주하고, GQM 방법론에 의해서 소프트웨어 프로세스 개선을 수행함으로써 조직의 비전과 목표 프로세스 능력을 달성할 수 있도록 제안한다. 또한, 결함 제거를 위한 트리거를 구축하고, 개선 사항과 타 프로세스와의 연관성을 분석하여 효과적인 프로세스 개선을 유도하고자 한다.

  • In this study, we carried out transient radiation experiments for identify failure situation by a transient radiation effect on DC/DC converter device due to high energy ionizing radiation pulse induced to electronic device. This experiments were carried out using a 60 MeV electron beam pulse of the LINAC(Linear Accelerator) facility in the Pohang Accelerator Laboratory. In this experiment, we has found that the latch-up phenomena could be checked in more than $1.0{\times}10^8$rad(si)/sec condition.

  • This paper presents a novel ultrasonic sensor system to overcome limited distance detection range that can be measured only more than 30cm by single ultrasonic transducer. This is accomplished by separation of receiving capacitive ultrasonic transducer from transmitting capacitive ultrasonic transducer. And hardwares and software of the system are described in detail. The system makes very close range as well as long range detect by wireless precisely. Frequency of trigger pulse is 10Hz, but it is very low frequency for transmitting data in wireless module. Therefore, for triggering between receiver and transmitter, an algorithm for mixing and distinguishing trigger pulse from carrier pulse by software is proposed. The system is designed by common microprocessor 8051. The performance of the proposed method has been assessed through two types. The first, transmitting and receiving transducer are put on both sides. And then, distance of two point is measured as far as 0mm. Secondly, transmitting transducer send out ultrasonic pulse and measure the time of flight(TOF) until a first echo from an object detected by the detached receiving transducer. The distance between the detached transducers and a reflecting object is measured as far as 7cm. Images of measured ultrasonic waves and TOF for two methods presented to prove effectiveness of results.

  • The research of vehicle license plate recognition has been widely studied for the smart city project. The license plate recognition can be hard due to the geometric distortion and the image quality degradation in case of capturing the driving car image at CCTV without trigger signal on the road. In this paper, the high performance vehicle license plate recognition system using edge-based segment image is introduced which is robust in the geometric distortion and the image quality degradation according to non-trigger signal. The experimental results of the proposed real time license plate recognition algorithm which is implemented at the CCTV on the road show that the plate detection rate was 97.5% and the overall character recognition rate of the detected plates was 99.3% in a day average 1,535 vehicles for a week operation.
