The invention provides a file storage method, a file search method and a file storage system based on public-key encryption with keyword search. The method comprises: receiving a user file storage request sent from a data possessor, acquiring access control attribute information for access to a user file, security level parameters and a keyword set of the user file, generating a file attribute vector of the user file by means of the access control attribute information and the keyword set, acquiring a public-secret key pair used for encrypting the file attribute vector from a pre-generated key space, encrypting the file attribute vector by means of a public key in the public-secret key pair to obtain a ciphertext corresponding to the file attribute vector, and transmitting the ciphertext corresponding to the file attribute vector and a ciphertext of the user file to a preset storage server.

A method is provided for heat transfer from a surface to a fluid. The method includes directing a first fluid flow towards the surface in a first direction and directing a second fluid flow towards the surface in a second direction. The first and second fluid flows cooperate to cool the surface.

Heat transfer apparatus and method

A power-on reset circuit includes a first circuit and a second circuit. The first circuit include a first NMOS transistor having a gate controlled by a low voltage supply VDD_L, a resistor connected between the source of the first NMOS transistor and a voltage supply VSS that is lower than VDD_L, and one or more diodes serially connected between a high voltage supply VDD_H and the drain of the first NMOS transistor. The second circuit includes a first PMOS transistor having a source connected to VDD_L, a second PMOS transistor having a source connected to the drain of first PMOS transistor, a second NMOS transistor connected between the drain of the second PMOS transistor and VSS, and an inverter configured to output a signal in response to the power on of the high voltage supply VDD_H and the low voltage supply VDD_L.
