Abstract:
A device for performing wireless communication at least one processor configured to generate a condition signal based on at least one parameter associated with the device or the wireless communication, and select at least one of a plurality of signal processing algorithms for performing at least one of a plurality of signal processing functions based on the condition signal, each of the plurality of signal processing functions being associated with the wireless communication.
Abstract:
A sensor arrangement method is provided. The method includes, in response to an event to additionally arrange a first sensor in a preset service area occurring, identifying sensing coverage and network coverage of a second sensor based on position information, state information, and network information of a pre-arranged at least one second sensor, and determining an arrangement position of the first sensor based on sensing coverage and network coverage of the second sensor, and sensing coverage and network coverage of the first sensor.
Abstract:
Provided are a data communication method using a secure element and an electronic system adopting the same. The data communication method includes: exchanging certificate information between an application processor of an electronic device and a secure element; setting up a secure channel through mutual authentication between the application processor and the secure element by using a public key and a secret key after the exchange of the certification information; and performing data communication between the application processor and the secure element through the secure channel.
Abstract:
A server and a method of controlling a group action of the server are provided. The server can determine whether a conflict occurs between a first group action that is being executed and a second group action that is requested to be executed and determine at least one conflict solution, and the method controls the execution of the group actions by the server and the determination and communication of the conflict solution. The conflict can be determined by using group action characteristics of the first group action and the second group action.
Abstract:
A fuel cell electrode catalyst including an active complex including a cerium (Ce)-nitrogen (N) bond and having an oxygen reduction activity of at least 1 milliampere per square centimeter at 0.5 volts versus a reversible hydrogen electrode.
Abstract:
A method for removing organic materials includes providing a target object having the organic materials adsorbed thereon, and an adsorbent, into a space including a non-liquid medium therein; and separating the organic materials from the target object by applying ultrasound waves to the target object having the organic materials adsorbed thereon and the adsorbent in the space, and disposing the organic materials to the adsorbent.
