    Abstract: Lithium-ion cells are widely used in various platforms, such as electric vehicles (EVs) and mobile devices. Complete and fast charging of cells has always been the goal for sustainable system operation. However, fast charging is not always the best solution, especially in view of a new finding that cells need to rest/relax after being charged with high current to avoid accelerated capacity fading. A user aware charging algorithm is proposed which maximizes the charged capacity within a user-specified available charging time (i.e., user-awareness) while ensuring enough relaxation (i.e., cell-awareness) and keeping cell temperature below a safe level.

    Abstract: Although GPS has become a standard component of smartphones, providing accurate navigation during the last portion of a trip remains an important but unsolved problem. Despite extensive research on localization, the limited resolution of a map imposes restrictions on the navigation engine in both indoor and outdoor environments. To bridge the gap between the end position obtained from legacy navigation services and the real destination, a “last-mile” navigation system is proposed to enable plug-and-play navigation in indoor and semi-outdoor environments. The system exploits the ubiquitous, stable geomagnetic field and natural walking patterns to navigate the users to the same destination taken by an earlier traveler. Unlike existing localization and navigation systems, the proposed system is infrastructure-free, energy-efficient and cost-saving.

    Abstract: Research efforts to detect and prevent possible attacks on vehicles have led to various defense schemes that are capable of preventing attacks and/or determining the presence/absence of an attack on the in-vehicle network. However, these efforts still cannot identify which Electronic Control Unit (ECU) on the in-vehicle network actually mounted the attack. Moreover, they cannot detect attacks by an adversary that impersonates ECUs injecting in-vehicle messages aperiodically. Identifying the source of an attack is essential for efficient forensic, isolation, security patch, etc. To fill these gaps, a method is presented for detecting and identifying compromised ECUs in a vehicle network.

    Abstract: A technique is presented for controlling behavior tracking by mobile apps executing on a mobile computing device. A set of profiles are managed by a privacy manager, where each profile represents a different isolated execution environment on the mobile computing device and defines a set of privacy rules governing an application while executing in an associated execution environment. Prior to launching the app, a user of the app is prompted by the privacy manager to select a profile for the app from the set of profiles. The privacy manager in turn applies the set of privacy rules associated with the selected profile to the app during execution of the app on the mobile computing device.

    Abstract: A method is presented for controlling power output by a battery in a vehicle. The method includes: measuring voltage of the battery during a sequence of vehicle events to form a time series, where each vehicle event is powered by the battery; constructing an unknown fingerprint from the voltage measurements made during the sequence of vehicle events, where the unknown fingerprint is indicative of a sequence of vehicle events; comparing the unknown fingerprint to the at least one fingerprint; receiving a start signal, where the start signal is a request to start the engine of the vehicle; and, in response to receiving the start signal and based on the comparison of the unknown fingerprint to the at least one fingerprint, outputting electric power from the battery to an electric starter motor of the vehicle.
