Abstract: A method and an apparatus for sharing a file with at least one peer terminal by a terminal in a Peer-to-Peer (P2P) network are provided. The method includes dividing a file allowed to be shared and generating two or more fragment files; generating file division information used for reconstructing the file allowed to be shared by using the fragment files; combining the file division information with each of the fragment files; and transmitting the combined file division information and fragment files to the at least one terminal.

Abstract: A mobile device and method are provided for controlling messaging. The method includes receiving a send request for a message from a user; analyzing a writing style of content of the message; comparing the writing style with a user behavior pattern that is pre-set for a standard writing style of the user to determine whether a non-standard writing style is detected; and withholding sending the message, upon detecting the non-standard writing style.

Abstract: A method or system for optimizing a process for producing a cast or molded product made by one or more production steps in respect of one or more predetermined parameters towards one or more optimal values, the process comprising the steps of: defining one or more technical requirements for the cast or molded product; providing a simulation of the casting or molding process; generating with each computer implemented process one or more solutions for the production step concerned that will lead to a cast product that will fulfill the technical requirements; and determining in a further computer implemented process which combination of the individual solutions results in an actual process or in a selected sub-set of production steps in which the predetermined parameter is closest to the optimal value.
