Abstract: Provided are a battery state estimation method and system and a recording medium for performing the method. The battery state estimation is provided by applying an ARX model and a dual extended Kalman filter. A battery state estimation system estimates a parameter of a battery model using an ARX model and estimates a battery state by applying the estimated parameter of the battery model to a dual extended Kalman filter including a state filter used to estimate a state of charge (SOC) and a weight filter used to estimate a state of health (SOH) of the battery.

Abstract: An Android dynamic loading file extraction method includes checking if at least one call of DexClassLoader, BaseDexClassLoader, PathClassLoader and openDexFile is made to a decompile code of Android Application Package (APK), hooking a dynamic loading method created in dynamic loading mechanism when the at least one call is made, extracting a dex path from the dynamic loading method, identifying if a File.delete method is invoked when the dex path is extracted, hooking the File.delete method when the File.delete method is invoked, extracting a path of the File.delete method and identifying if the path of the File.delete method is matched with the dex path, and extracting a dex file or jar file from the decompile code of APK when the path of the File.delete method is unmatched with the dex path. Accordingly, the dex file used in dynamic loading mechanism of the malicious application is extracted, and static analysis of the hidden codes is conducted using reverse engineering mechanism.

Abstract: A method and apparatus for generating a font of which style is changeable are disclosed. The disclosed method is a method for generating a font to be performed on an apparatus including a processor. The method comprises (a) setting a fixed style parameter which cannot change the style, wherein the fixed style parameter is included in style parameters, and a METAFONT consists of the style parameter and a letter drawing function, (b) generating an intermediate code based on the letter drawing function and the fixed style parameter; and (c) generating an output font by combining the intermediate code with a variable style parameter which can change the style, wherein the variable style parameter is included in the style parameter.
