Abstract: The subject matter described herein relates to a file system with adaptive flushing for an electronic device. The file system keeps data in memory much longer and its policy for flushing in-memory write cache to storage is application-aware and adaptive. More specifically, what parts of the cached data are ready for flushing could be determined according to the access characteristic of an application. In addition, when to do flushing can be selected flexibly at least partly based on user input interactions with an application of the electronic device or with the electronic device. Further, a multi-priority scheduling mechanism for scheduling data units that are ready to be flushed could be employed, which ensures fairness among applications and further improves flushing performance.

Abstract: A framework for use in developing proximity-based social interactions (PSIs) shows energy efficiency, topology robustness, and a lessened load for group participants. Implementations of the framework may include PSI-specific application hints to aggregate and schedule pending transmissions and match delivery requirement, topology structure and maintenance schemes that provide robustness and improve efficiency, and load-distributing group dissemination protocols.

Abstract: Application testing and analysis may include performing perturbations to affect an environment associated with the application executing on a user device without affecting other applications executing on the user device. The execution of the application may be traced while the perturbations are being performed to determine an amount of resources of the user device consumed by the application and to determine whether a performance of the application was degraded.

Abstract: Some implementations disclosed herein provide techniques and arrangements to enable interactive zones. For example, some implementations detect that a user has entered a zone associated with a physical object, where the zone is created via magnetic induction. In response to detecting that the user has entered the zone, some implementations send a virtual object representation of the physical object to a user device (e.g., a wireless phone) associated with the user. The user may interact with the virtual object, including selecting a command associated with the virtual object. Selecting the command may cause the physical object to perform one or more actions. In some implementations, a result of the physical object performing the one or more actions is sent to the user device.

Abstract: Systems and methods that provide for collection of sensor data in a wireless network with a dynamically changing structure. A data collection protocol exploits the self-awareness capabilities of nodes in selection of tree structures that form the wireless network during communication with a base station. The data collection protocol can further include a topology control component (which regulates how nodes are distributed among various tree structures and associated communication channels with the base station) and data retrieval component (which coordinates among the sensors to transmit data packets containing sensor data to efficiently employ available bandwidth).
