Abstract: Provided is a method for regulating a thermal boundary conductance between a metal and an insulator, including: arranging a metal on a surface of an insulator, a contact surface between the metal and the insulator being a boundary between the metal and the insulator; and the insulator including a ferroelectric, a piezoelectric, or a pyroelectric; applying an external electric field or stress to the ferroelectric, and adjusting a magnitude of the external electric field or stress, or an included angle between a direction of the external electric field or stress with the boundary to regulate the thermal boundary conductance; or applying a stress to the piezoelectric, and adjusting a magnitude of the stress, or an included angle between a direction of the stress with the boundary to regulate the thermal boundary conductancer; or adjusting a temperature of the pyroelectric to regulate the thermal boundary conductance.

Abstract: A server to reconstruct a browsing history of a mobile device, including an internet crawling module to initiate an internet crawling application to receive a generated website signature descriptive of internet protocol (IP) addresses' access to a website and its associated resources; a transmission control protocol (TCP) reception module to receive a created signal descriptive of a TCP packet comprising IP addresses of resources received and stored on a mobile device; and a processor to compare the signature with the signal to determine if a computing device associated with the signature accessed the website associated with the signal address in order to reconstruct the browsing history.
