Abstract: A system and method for processing a secure financial transaction using a Commercial off-the-shelf (COTS) or Internet of Things (IoT) device is provided. The method comprises requesting a Trusted Application Manager (TAM) to verify the COTS/IoT device identity and executing an application on a COTS/IoT device. Upon verification, TAM installs a Trusted Application (TA) in a Trusted Execution Environment (TEE) of the COTS/IoT Device. Further, initiating a resonance response when a tag is within a predetermined distance from the COTS/IoT device with TA installed, and receive the tag information from the tag. Finally, processing a secure financial transaction using the COTS/IoT device based on the received tag information by accessing the TEE. The COTS/IoT device includes a distributed ledger, and which comprises information corresponding to at least one of COTS/IoT device ownership, manufacture, and usage information.

Abstract: A low Reynolds number airfoil for a wind turbine blade, the airfoil having a leading edge 101, a trailing edge spaced from the leading edge 101, a chord 120 defined as a straight line joining the leading edge 101 and the trailing edge, a chord 120 length defined as distance between the trailing edge and the point on the leading edge 101 where the chord 120 intersects the leading edge 101 wherein the airfoil comprises a camber 121 between 5% to 7% of the chord 120 length, the camber 121 is disposed within a distance of 17% of the chord 120 length from the leading edge 101 and a thickness of the airfoil not greater than 7% of the chord 120 length.
