Relationships between the coefficient of thermal conductivity (CTC) and the strength properties of wood were investigated.Small clear test specimens were prepared from beech, fir, and pine wood.CTC values of the test specimens were measured based on the ASTM C 1113-99 hot-wire method.Wood density and some mechanical properties were then determined
The surface of read more the Moon and planets have been covered with loose soil called regolith, and there is a risk that the rovers may stack, so it is necessary for them to recognize the traveling state such as its posture, slip behavior, and sinkage.There are several methods for recognizing the traveling state such as a system using cameras and
Hybrid filter bank (HFB) is widely used in frequency-interleaved analog-to-digital converters, but traditional HFB structures suffer various degrees of imperfections.This paper presents a new-structure HFB based on power complementary pair.The socialstudiesscholar.com proposed architecture only needs M-1 analog analysis filters in M-channel frequen
