of a secondary battery is not enough to replace the existing engine, it still needs to have both battery-powered motor and engine to generate enough power.
Clean Diesel
The diesel car has been recognized as the main culprit of air pollution, but people are beginning to understand the diesel car in a different way. The clean diesel engine has a mechanism of compressed air and blast, and it

Abstract
In this experiment, three kinds of experiments were conducted. The first experiment, the single pendulum experiment, is to find out the change in period according to the change in the length of the string connected to the IMU ball. Through this, the measured value of the period and the theoretical value obtained by FBD were compared and the cause of the error was analyzed. The second
of the resistance read in color code. Their average error was 0.15% to 0.46%, and it was confirmed that all exist within 1%, which is the tolerance of resistance. In the second experiment, change the waveform, frequency, peak to peak amplitude, DC Offset, Voltage, and Timebase values using a function generator and oscilloscope, and compare how each parameter affects the shape of the wave.

컴퓨터가 자연적인 언어(natural language)를 처리하도록 하는 데에 있어서의 어려움에 대한 초기의 연구에서, Anthony Oettinger는 우리가 예상되는 구조(expected structure)에 기반하여 어떻게 문장을 번역하는지, 그리고 우리가 번역하며 오류를 범했을 때,

전류 값이 시간에 따라 변화하기 때문에 적분을 이용하여 면적을 계산해줘야 한다. 따라서 단순 계산이 어렵기때문에 일반적으로 전량계에 의존하여 전기량을 측정한다.

of the nozzle is raised at least 0.1mm (0.004 inch), which is equal to the thickness of good quality paper, or the supporting table is lowered an equivalent amount, and the process is repeated. In order to build an object the controlling drawing for each layer changes very slightly.
Typical standard manufacturing methods are subtractive, that is material is removed from a base form by machining
Ⅰ. Introduction
ⅰ. Background and necessity of the study
Safety management becomes a growing issue in the aspect of recent business administration. It helps to upgrade the quality of worker’s life and to reduce the financial loss.
The remarkable point is that there is little change in the strength rate, which represents damage scale from lack of labor – this labor loss is caused
