소음원의 중첩에 따른 SPL의 증가
오토바이 1에서 발생하는 소음을 L_1, 오토바이 2에서 발생하는 소음을 L_2라 하고, 오토바이 1과 오토바이 2에서 동시에 발생하는 소음을 L_(1+2)라 하면 다음과 같은 관계가 성립한다.
L_(1+2)=10log(〖10〗^(L_1/10)+〖10〗^(L_2/10) )

method, along with an improvement in the yield. Two major parameters were controlled to optimize the growth properties of the gold nanorods, namely their kinetics and anisotropic growth. In the case of the first parameter, we observed that slowing the growth of the Au nanorods increases their aspect ratio. In other words, anisotropic growth can be facilitated at low temper- ature. Recently, it ha

Part 1:
A. Describe the cost flow assumptions used in average cost, FIFO and LIFO methods of inventory valuation.
-The average cost method assumes cost of goods sold and ending inventory consist of a mixture of all the goods available for sale. The average unit cost applied to goods sold or to ending inventory is not simply an average of the various unit costs of purchases during the pe
two decades, cardiovascular mortality rates have declined in many high-income countries. At the same time cardiovascular deaths and disease have increased at an astonishingly fast rate in low- and middle-income countries. There are various kinds of heat disease like coronary heart disease, cardiomyopathy, hypertensive heart disease, and so on.

methods that can be measure Young's modulus with reliability and reappearance are needed to develop the new materials i.e. composite and thin film materials.
In general, there are twomethods to measure the Young's modulus. The first one is called the 'static method' that is the way to measure the deformation strain that are corresponded to applied force using the strain gage. In other way, 'k
