Aggregating bandwidth from multiple radio access technologies (RATs) provides an opportunity for network providers to enhance network capacity. This is important for serving applications that require more bandwidth than a single RAT can offer. One of the important elements of bandwidth aggregation is the selection of a suitable set of RATs to achieve efficient aggregation. In this paper, we pro...

Buffered crossbar switches are special crossbar switches with each crosspoint equipped with a small exclusive buffer. The crosspoint buffers decouple input ports and output ports, and simplify switch scheduling. In this paper, we propose a scheduling algorithm called Fair and Localized Asynchronous Packet Scheduling (FLAPS) for buffered crossbar switches, to provide tight performance guarantees...

This paper proposes a new MPEG-4 rate control algorithm for single or multiple object video sequences. The algorithm aims to achieve an accurate bit rate with the maximum picture quality while efficiently handling buffer fullness and scene change. In addition to estimating the bit budget of a frame based on its global coding complexity, the algorithm dynamically distributes the target bits for ...

Sum frequency generation (SFG) vibrational spectroscopy and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) were used to investigate the orientation of N-terminus cysteine-modified cecropin P1 (cCP1) at the polystyrene maleimide (PS-MA)/peptide phosphate buffer solution interface. The cCP1 cysteine group reacts with the maleimide group on the PS-MA surface to che...

A class of commonly asked queries in a spatial database is known as buffer queries. An example of such a query is to “find house-power line pairs that are within 50 meters of each other.” A buffer query involves two spatial data sets and a distance d. The answer to this query are pairs of objects, one from each input set, that are within distance d of each other. Given nonpoint spatial objects,...

Since 1998, StackGuard patches to GCC have been used to protect entire distributions from stack smashing buffer overflows. Performance overhead and software compatibility issues have been minimal. In its history, the parts of GCC that StackGuard has operated in have twice changed enough to require complete overhauls of the StackGuard patch. Since StackGuard is a mature technology, even seeing r...
