We present the wireless routing protocol (WRP). In WRP, routing nodes communicate the distance and second-to-last hop for each destination. WRP reduces the number of cases in which a temporary routing loop can occur, which accounts for its fast convergence properties. A detailed proof of correctness is presented and its performance is compared by simulation with the performance of the distribut...

Dibenzofuran degrading bacteria were enriched from various environmental sources. A mutualistic mixed culture of strain DPO 220 and strain DPO 230 was characterized. Strain DPO 220 alone showed limited growth with dibenzofuran as sole source of carbon and energy (td greater than or equal to 4.5 h). A labile degradation product, C12H10O5, and salicylate were isolated from the culture fluid. Sali...

Staggered SAR is an innovative synthetic aperture radar (SAR) concept, where the pulse repetition interval (PRI) is continuously varied. This, together with digital beamforming (DBF) in elevation, allows high-resolution imaging of a wide continuous swath without the need for a long antenna with multiple azimuth apertures. Criteria for the design of sequences of PRIs and data processing strategi...

This paper presents the description and performance tests of an L-band microwave radiometer with Digital Beamforming (DBF), developed for the Passive Advanced Unit (PAU) for ocean monitoring project. PAU is an instrument that combines, in a single receiver and without time multiplexing, a microwave radiometer at L-band (PAU-RAD) and a GPS-reflectometer (PAU-GNSS-R). This paper focuses on the PA...

We give an alphabet-independent optimal parallel algorithm for the searching phase of three-dimensional pattern-matching. All occurrences of a three dimensional pattern P of shape mmm in a text T of shape n n n are to be found. Our algorithm works in log m time with O(N= log(m)) processors of a CREW PRAM, where N = n 3. The ideas from 3] are used. Surprisingly, the extension of the two dimensio...

Understanding and accounting for gender performance differences on high stakes examinations has become a particular concern for educational researchers to ensure test fairness for all examinees. In the context of second/foreign language proficiency testing, research (Ryan and Bachman, 1992) suggests that males and females do not react differently at the item level. However, as Nandakumar (1993)...
