Abstract: A system and method for detecting sensitive user input leakages in software applications, such as applications created for smartphone platforms. The system and method are configured to parse user interface layout files of the software application to identify input fields and obtain information concerning the input fields. Input fields that contain sensitive information are identified and a list of sensitive input fields, such as contextual IDs, is generated. The sensitive information fields are identified by reviewing the attributes, hints and/or text labels of the user interface layout file. A taint analysis is performed using the list of sensitive input fields and a sink dataset in order to detect information leaks in the sensitive input fields.

Abstract: Systems and methods for optimizing power flows using a harmony search, including decoupling phases in a multi-phase power generation system into individual phase agents in a multi-phase power flow model for separately controlling at least one of phase variables or parameters. One or more harmony segments from harmony memory are ranked and selected based on a utility value determined for each of the decoupled phases. A harmony search with gradient descent learning is performed to move the selected harmony segments to a better local neighborhood. A new utility value for each of the selected segments is determined based on historical performance, and the harmony memory is iteratively updated if one or more of the new utility values are higher than a utility value of a worst harmony segment stored in the harmony memory.

Abstract: Methods and systems of sensing conditions in a fiber includes launching a light beam into a fiber. A first branch of scattered light is set to a mode other than a fundamental mode. A second branch of scattered light is optically filtered to remove unscattered input light. Brillouin scattered light is coherently detected on the first branch to produce a combined temperature/strain profile of the fiber. Raman scattered light on the second branch is directly detected to produce a temperature profile of the fiber. A strain profile of the fiber is determined, using a processor, based on the combined temperature/strain profile and the temperature profile.
