Abstract: Various examples include an apparatus to characterize substrate and film thicknesses of the substrate and films formed thereon. The apparatus uses one or more wavelengths of light from a light source (e.g., a swept laser) to interrogate the substrate. The light is directed substantially orthogonally to an upper surface of the substrate. A polarizer and an analyzer element are coupled between the light source and the substrate. Therefore, the polarizer and the analyzer are both located in the beam propagation path from the light source to the substrate. An optical detector is arranged substantially orthogonally to the upper surface of the substrate. The optical detector receives light returned back from the substrate. The apparatus is capable of determining the thickness of the substrate and one or more films contained thereon, regardless of substrates having optical anisotropies, such as chiral characteristics or stress-induced films. Other apparatuses and methods are also disclosed.

The server communicates with a connector grid server to retrieve the user's accessible documents. The connector grid server determines the electronic file IDs that are accessible to the user based on the accessibility policy. The server instructs a digital library server to download the electronic files containing the requested trade data. The digital library server retrieves and downloads the electronic files based on the file IDs. The webserver renders a GUI displaying the electronic files on an electronic client device operated by the user. Upon receiving the confirmation response from the user, the server instructs the digital library server to update the trade status.

Abstract: A fluid-induced vibration energy harvesting apparatus with a non-rotating bluff body is provided. The apparatus does not use a common design method of rigidly securing a bluff body to an elastic beam in a design of the bluff body, but adopts a manner of connecting the bluff body and the elastic beam through a rotating shaft and a connecting shaft. Because a kinematic pair at a connection position is a rotating pair, the bluff body will only vibrate transversely and will not rotate, thereby achieving an effect of increasing an amplitude at the same frequency, and finally realizing an increase of converted electric energy and improving the conversion efficiency.

Abstract: The present invention provides a transaction method and a node design in a blockchain system. A client initiates a transaction by using an SQL write command including transaction data or queries transaction data by using an SQL query command. A node parses an SQL command, executes a simulated transaction, and checks block data based on a transaction result of the simulated transaction after obtaining the block data. After the check succeeds, the node converts the block data into an SQL write command used to write the block data, thereby writing the block data to an RDB database. In embodiments of the present invention, an RDB data block is connected to the blockchain system, so that data query and processing capabilities of the blockchain system are improved.
