A method for estimating a central frequency includes defining a slice group containing a plurality of slices parallel to one another within an arbitrary imaged region in a subject, measuring a central frequency of at least one slice contained in the slice group, and estimating central frequencies of the other slices based on the measured central frequency of the at least one slice.

A method for providing a signal to a light control unit of at least one headlight of a vehicle that has a camera for acquiring a surrounding environment of a vehicle, the method including a step of determination of an interval between the vehicle and another vehicle using the camera. The method further includes a step of determination of a distance between the vehicle and the other vehicle using a camera-independent sensor. In addition, the method includes a step of plausibilization of the interval using the distance, the interval being plausibilized if a difference between the interval and the distance is smaller than a tolerance value. Finally, the method includes a step of provision the interval via an interface to a light control unit of the headlight.

The invention discloses a nuclear power plant reactor loading and unloading state simulation system and method. The system comprises a management module, a reactor workshop building module and a fuelworkshop building module; the management module is used for storing the historical storing states, fuel component serial numbers, related component serial numbers and reactor loading and unloading moving plans of a reactor core and a spent fuel storing water pool; the reactor workshop building module is arranged in a reactor workshop building, the fuel workshop building module is arranged in a fuel workshop building, and the reactor workshop building module and the fuel workshop building module are used for reading data in the management module and calculating the initial states of the reactorcore and the spent fuel storing water pool before loading and unloading; in the initial states, the reactor loading and unloading moving plans for loading and unloading are read and executed from themanagement module, and the states of the reactor core and the spent fuel storing water pool in all steps are simulated and displayed according to the loading and unloading progress; and the fuel operation states of the opposite workshop buildings are read and displayed according to information sharing of the reactor workshop building module and the fuel workshop building module. According to thenuclear power plant reactor loading and unloading state simulation system and method, accurate and quick simulation of the reactor loading and unloading process and states is achieved, and the operation efficiency is improved.

The invention discloses a method and system for realizing a trusted time stamp service based on blockchain, which belongs to the technical fields of blockchain, hyperledger fabric, and hash algorithm. The technical problem to be solved by the invention is how to realize the removal of third-party The technical solution adopted by the organization's trusted time stamp service is as follows: ①The method is as follows: super ledger fabric blockchain network construction and user registration; trusted time stamp generation: users use hash algorithm to perform hash operation on electronic data Obtain the abstract, write the relevant information of the electronic data into the blockchain, and at the same time use the transaction time of the corresponding transaction as the time point corresponding to the trusted timestamp, and then return the json structure composed of the transaction key value, transaction hash and timestamp As a trusted timestamp; trusted timestamp verification. ②The system includes a hyperledger fabric block chain network construction and user registration unit, a trusted timestamp generation unit and a trusted timestamp verification unit.
