In solar power system, the height and azimuth of the sun are important parameters which control generated power magnitude. The tracking method that controls the daily generation magnitude according to latitude and longitude using the two axles is often used in the existing sunlight tracking system today. In this two-axle PV track control system, the self-load is concentrated on one FRAME. It is influenced of the regular load, snow load and the wind load, etc. It is difficult to set up the system in the conventional building. This research is a development about the small-scale economy track device of independent load-dispersing solar generation system. The position tracking algorithm is through the new coordinates transformation calculating the height and azimuth of the sun.

피크용 분산전원은 계통의 전체 운영비용을 줄일 수 있고, 대기용 분산전원은 수용가의 신뢰도를 향상시킬 수 있다. 피크용 분산전원과 대기용 분산전원은 해석하는데 있어서 다른 모델링을 세워야 하고 그에 따라 다른 방식으로 해석해야 하는데 이를 구현하기 위해서는 Monte-Carlo시뮬레이션 기법이 적합하다고 할 수 있다. 본 논문에서는 순차적 시뮬레이션 기법을 통해 두 가지 분산전원의 영향을 신뢰도 지수로 표현하고 이를 통해 두 가지 분산전원의 장단점을 살펴보도록 하겠다.

Using random numbers to represent uncertainty and unpredictability is essential in many industries. This is crucial in disciplines like computer science, cryptography, and statistics where the use of randomness helps to guarantee the security and dependability of systems and procedures. In computer science, random number generation is used to generate passwords, keys, and other security tokens as well as to add randomness to algorithms and simulations. According to recent research, the hardware random number generators used in billions of Internet of Things devices do not produce enough entropy. This article describes how raw data gathered by IoT system sensors can be used to generate random numbers for cryptography systems and also examines the results of these random numbers. The results obtained have been validated by successfully passing the FIPS 140-1 and NIST 800-22 test suites.

High strength concrete increasingly used in various countries. Recently, great attetion is also paid to the high strength concrete in this country. To promote the actual application of high strength concrete, several series of high strength concrete have been made and applied to actual structures. The mechanical properties and the temperature rise due to generation of hydration heat have been also studied. The present study provides a firm base for the actual application of high strength concrete in the field.

In this paper an automated hole-finding method for overset grids is introduced which uses recursive octree-cell division. A graphic program which enables the user to do the hole-cutting with ease is also introduced. Using this program it was found that a proper combination of the level of octree division and vector calculation should be used for efficient and fast hole finding.

This paper treats with the design and fabrication of a frequency synthesizer for the generation of intermediate frequency of a HF band transceiver. The synthesizer is designed to control frequencies using a phase-locked loop and it is shown that method improved the performance of frequency accuracy and locking time then that of the crystal-reference system.

As the manufacturing capacity needs for large size LCD TV shifts very fast into next generation, equipment manufactures face more challenges in development of the systems which can accommodate productivity, reliability and high process quality requirements from the panel makers. AKT committed to continue its contribution to the growth of the LCD market by providing excellent PECVD products. The cost containment and performance improvement are key challenges for large size processing equipment development and this presentation discusses various challenges and AKT's solutions in developing large size PECVD equipment beyond Gen. 8.

The main objectives of this dissertation is to propose a forth generation index C for the case where the target value T is not equal to the midpoint of the specification limits (i.e. asymmetric tolerances), and show that this index is more sensitive compared to the standard PCI's in detacting small shifts of the process mean from the target value. In conclusion, in this dissertation , a new methods for estimating a measure of process capability for non-normally distributed variable data is proposed using the percentage nonconforming.
