Disclosed herein are systems and methods for profile-based forecasting with dynamic profile selection. Speed differentiation is provided by a differential that includes a differential gear assembly supported within a differential case. An exemplary formula and a suitable machine for manufacturing are also disclosed. Functional data may be stored in a functional information database and linked to the PNR by a functional element stored in the PNR that identifies a location of the functional data in the functional information database. The present invention further provides a method of accurately and stably analyzing the amount and ratio of oxidized and reduced albumin in a sample solution, and an albumin standard accurate and controlled quantitative analysis of albumin. The data includes wheel speed, road inclination, moisture associated with a surface of the braking system, and audio associated with the road.
