Abstract: The disclosure provides systems and methods for data analysis of experimental data. The analysis can include reference data that are not directly generated from the present experiment, which reference data may be values of the experimental parameters that were either provided by a user, computed by the system with input from a user, or computed by the system without using any input from a user. Another example of such reference data may be information about the instrument, such as the calibration method of the instrument.

Abstract: A reusable fastener that secures the zippers of a dual closed-ended zippers mechanism in the mechanism's closing position. The reusable fastener secures products that are dependent on the dual closed-ended zippers mechanism for actions of opening and closing from being unintentionally opened. While able to secure zippers of the dual closed-ended zippers mechanism in the closing position, the reusable fastener can also be easily detached. Additionally, the detachment process will not destroy the reusable fastener, enabling the reusable fastener to be reused. Furthermore, since no personally-tailored knowledge or lock-and-key is necessary to detach the reusable fastener, public and safety officials can securely reattach the reusable fastener to the zippers after inspections. The reusable fastener contains a plate that will make the reusable fastener easily identifiable. These advantages of the reusable fastener will provide users of products containing the dual closed-ended zippers mechanism a peace of mind.
