Abstract: In some embodiments, a method receives a statement graph for a procedure that is used to access data and determines a set of producer statements and a set of consumer statements in the statement graph. A producer statement produces a variable for a consumer statement, and the consumer statement consumes the variable from the producer statement. The method optimizes the statement graph to generate an optimized procedure by moving an operator from a consumer statement to a producer statement or by moving an operator from a producer statement to a consumer statement. The optimized procedure is output based on the optimized statement graph.

Abstract: A mechanism for changing a rack stroke of a steering system includes a limiter that is rotated by a motor, a stopper that limits the rack stroke by contacting the limiter, and a controller that controls the motor based on vertical motion of a wheel. The limiter includes one or more first spiral slopes. The stopper includes one or more second spiral slopes in contact with the first spiral slopes. The limiter may be ring-shaped. The first spiral slopes may be disposed along the circumference of the limiter. The limiter may further include one or more rotation stopping blocks which protrude between the spiral slopes. The stopper may include a center body that is rotatably inserted between the rotation stopping blocks, and one or more protrusions that radially protrude from the center body. The second spiral slopes may be disposed on the protrusions.
