Abstract: Embodiments of a system and method for generating a shaped cyclic time-domain waveform are generally described herein. In some embodiments, a first transform may be performed on an input symbol vector to generate a transformed input vector in a transform domain. The transformed input symbol vector may be expanded to generate an expanded symbol vector. At least some elements of the expanded symbol vector may be weighted with a weighting vector selected for pulse shaping to generate a weighted symbol vector. A second transform may be performed on the weighted symbol vector to generate an output symbol vector for subsequent processing and transmission. The second transform may be an inverse of the first transform and may comprise a greater number of points than the first transform.

Abstract: The systems and methods of the invention modulate atmospheric gases to temporarily increase the amount of atmospheric particles in the path of the debris, in order to decelerate the debris and accelerate natural orbital decay to the point of atmospheric re-entry. In one aspect of the invention, clearing the space debris includes propelling a plume of atmospheric gases substantially orthogonal to the path of the debris such that the debris collides with the gaseous plume as it passes through the plume. Increased atmospheric drag from the gaseous particles of the plume in the path of the debris obstructs a forward propagation of the debris and gradually decelerates the debris, leading eventually to atmospheric recapture. Embodiments of the invention can be employed in any number of applications, including without limitation, clearing debris in the low-earth orbit (LEO) which is particularly susceptible to debris build-up, de-orbiting non-refuse payloads front orbits, and clearing debris from geosynchronous orbits.

Abstract: Embodiments of a system and method for managing transceiver resources in a wireless network are generally described herein. In some embodiments, a transceiver resource manager (MXRM) dynamically adapts the number of transceivers to an offered load. A node computes the number of transceiver it needs based on queue depth and queue usage. MXRM then shares the number of the transceivers to be requested, A, with next-hop neighbors. A node assigns X transceivers such that X is the maximum of their own A value and the highest A value they receive if they are next-hop targets. MXRM processes requests for additional transceivers from nodes and previous-hop neighbors such that the sender-receiver pair assigns a compatible number of transceivers. MXRM is also used to drive frequency assignments to increase capacity along the traffic flows. Therefore, MXRM adapts transceiver assignments to the traffic paths.

Abstract: A method for secure comparison of encrypted symbols. According to one embodiment, a user may encrypt two symbols, share the encrypted symbols with an untrusted third party that can compute algorithms on these symbols without access the original data or encryption keys such that the result of running the algorithm on the encrypted data can be decrypted to a result which is equivalent to the result of running the algorithm on the original unencrypted data. In one embodiment the untrusted third party may perform a sequence of operations on the encrypted symbols to produce an encrypted result which, when decrypted by a trusted party, indicates whether the two symbols are the same.

Abstract: An approach to segmentation or clustering of a set of elements combines separate procedures and uses training data for those procedures on labeled data. This approach is applied to elements being components of an image of text (e.g., printed or handwritten). In some examples, the elements are connected sets of pixels. In images of text, the clusters can correspond to individual lines. The approach provides improved clustering performance as compared to any one of the procedures taken alone.

Abstract: A method includes receiving a process request, identifying a current state of a device in which the process request is to be executed, calculating a power consumption associated with an execution of the process request, and assigning an urgency for the process request, where the urgency corresponds to a time-variant parameter to indicate a measure of necessity for the execution of the process request. The method further includes determining whether the execution of the process request can be delayed to a future time or not based on the current state, the power consumption, and the urgency, and causing the execution of the process request, or causing a delay of the execution of the process request to the future time, based on a result of the determining.
