Certain example embodiments relate to using Complex Event Processing (CEP) techniques for statistical analysis of cache behavior and parameters, e.g., in connection with large, potentially heterogeneous data sets (e.g., “Big Data”). A dedicated stream mining operator registers a listener to a cache and receives notifications on cache operations. For selected element attributes, a first model estimates the probability density functions of the attribute values, delivering well-defined estimates of the attribute value distributions. A second model analyzes the time elements stay in the cache (“validity”). Validity is combined with the attribute value distribution. A meaningful analysis model (Cache Element Model) can be derived by combining additional summary statistics for the validity with the attribute value distribution, describing how long elements stay in the cache for attribute values of a specific region, and how the values are distributed. It may be used to inform administrative tasks such as, optimization of cache parameters.

Methods, systems and computer program products for tracking a client's usage of one or more services provided by one or more servers. A client generates and sends one or more metering packets to a census service. Each metering packet includes a time element indicating the client's usage of the one or more services. The time element may include a charged time portion and a free time portion. An authentication element may be included with each metering packet so that the census service can determine whether or not a given metering packet is genuine. A login service communicates to the client whether or not usage should be tracked and indicates a time interval to expire between subsequent metering packets. A session identifier in each metering packet allows multiple sessions to be tracked simultaneously. Upon receiving metering packets, the census service discards redundant metering packets and updates a usage database accordingly.

A method for target acquisition and tracking of a moving station or target (e.g., an unmanned aerial vehicle) for carrying out free space optical communications uses an “elapsed time”-based approach to determine the position of the moving station at any future time, based on the time difference since the moving station's last known position. For example, the vehicle may be for purposes of reconnaissance, where the optical link provides a secure and high-bandwidth communications pathway between the moving station and a ground station. A mathematical model of the moving station's expected periodic flight path is combined with position and time elements to accurately predict the future position of the moving station for target re-acquisition. The model is a cubic spline interpolation of known flight path waypoints. The system may also employ multiple waypoints in initial acquisition, by alternating acquisition attempts over several waypoints instead of “staring” at a single waypoint.

Original digital audio signals are represented as PCM sample values wherein the distance between the values corresponds to the sampling frequency. Digital signals can have a length that is an integer multiple only of this time element. In particular coded digital audio signals are processed block-based, leading to a total length that is a multiple only of the block unit. According to the invention, information about the exact length of the original signal is transferred together with the encoded audio information. Additionally, an information value can be transferred that represents the total encoder and / or decoder delay. The decoder extracts these items of information and adjusts the total length of the decoded signal by cutting off samples from the decoded program or track.
