Disclosed is a photosensitive resin composition that provides an excellent water developability, drying property, and image reproducibility. Further, a method of making the optical sensor is provided. The function of these switches is to periodically reverse the polarity of voltage across the inductors. The warm air narrowed at the blowing port obtains an increased air velocity thereof. The first predicted value of the designated rock or fluid property is adjusted in response to the difference to create a second predicted value of the designated rock or fluid property, wherein the second predicted value generally reduces the difference.
