Abstract: The present invention relates to a method of improving file write performance and providing availability in a hybrid storage system. When a file writing target server information request signal is received from a client, any one cache server is selected in consideration of storage spaces of cache servers, information about the selected cache server to the client is transmitted so that the client stores the file in the selected cache server. When a duplicate writing target server information request is received from the selected cache server, any one first data server is selected in consideration of storage spaces of respective data servers, information about the selected first data server is transmitted to the cache server so that the cache server stores a duplicate of the file in the first data server. Information about storage of the file and the duplicate is received, and then file metadata is stored.

Abstract: A wireless wake-up system and an operation method thereof are provided to optimize power consumption when wireless data is received. The wireless wake-up system activates a wake-up detection module and then compares a wireless input signal received through an antenna with a pre-stored reference value. If the wireless input signal is equal to the reference value, the wireless wake-up system determines that the input signal is a wake-up signal with a low bit rate, and then generates a wake-up command corresponding to the wake-up signal. Also, the wireless wake-up system activates a selected module kept in an inactive state by sending the wake-up command to the selected module. The activated module may be a microcontroller unit (MCU). When the MCU is activated, the wireless wake-up system may inactivate the wake-up detection module.

Abstract: In a retarget process modeling method, an effect according to density of patterns, and shapes or distances with respect to neighboring patterns may be sufficiently reflected while a relatively small amount of time and few costs are consumed. The retarget process modeling method involves obtaining prediction data, by a modelling calculating unit, on a test layout using a first process model, obtaining bias data based on measurement data of the test layout and the prediction data, using the bias data to check and detect corresponding features of a representative pattern affected by a photoresist (PR) flow rate, generating kernels including a PR flow kernel in consideration of a sub resolution assist feature (SRAF) pattern of the representative pattern to determine an uncalibrated model including the kernels and obtaining a second process model by fitting the uncalibrated model to the measurement data to obtain a second process model.

Abstract: An antitheft method and system for motorcycles are provided. The antitheft method and system for motorcycles authenticate an electronic identifier when power-up of a motorcycle or engine start-up is sensed and cut off the power-up or engine start-up if the power-up or engine start-up is not authenticated. An electronic control unit can generate a theft alarm signal in case of unauthenticated power-up or engine start-up. The motorcycle engine is automatically stopped if the engine is started through an illegal method, and thus the motorcycle is prevented from being stolen. Further, a user can confirm the electronic identifier and start the motorcycle without inserting a key into a key cylinder, and thus the user can start the motorcycle easily and rapidly.

Abstract: A method of reducing the influence of the spread of the transmitted light on the feature size during optical lithography is disclosed. The method comprises at least two irradiation steps. During a first irradiation the resist is exposed with the original mask, i.e., comprising substantially the pattern to be obtained in the layer. Thereafter, without developing the exposed resist, an irradiation with at least one exposure is performed whereby the resist is exposed with a second mask, being at least partly the inverse of the original mask. The exposures of the second irradiation step are defocused compared to the first irradiation.
