A software performance-analysis and installation method includes estimating performance of a system including a software component to be installed on the system and determining, based on the estimated performance, whether to install the software component in a current configuration. According to the invention, unison strings can be mechanically linked or coupled to align portions of their oscillatory patterns. The region specifying unit specifies a region where the superimposed sheet is represented in the second image data, based on a region where the deleted differential image data is. The vertically-integrated greenhouse involves the use of a dynamic movable array of plant trays as a mechanical shading device. The semiconductor element is connected to a conductive layer on a supporting board via a plurality of convex-shaped outside connection terminals provided on the outside connection terminal pad and a connection member; and the connection member commonly covers the convex-shaped outside connection terminals. A motor 202 is provided which additionally provides torque to the differential 206 during gear changes of the transmission 212 to minimize the affects of clutch shudder from an engine clutch 210.
