Designing scheduling algorithms that are simple to implement along with the process for servicing packets with low computation complexity is necessary to provide Qualityof-Service (QoS) for high-speed wireless *** ordinary frame-based scheduling algorithms are well-known for providing fair service with constant time complexity (O(1)),however,they have limitations of not being able to properly handle location-dependent burst errors in wireless *** utilize the advantage of frame-based scheduling algorithms,we propose a new Compensation Model which is based on Leadlag Model,to provide smooth compensation,so that frame-based scheduling algorithms can guarantee fairness and reduce delay in error-prone wireless *** the analytical model and simulation studies,we show that frame-based scheduling algorithms with Compensation Model can provide smaller delay bound and better fairness in wireless *** belief is that the proposed frame-based scheduling algorithm (WFRR) based on the graceful Compensation Model can be a strong candidate for the scheduling algorithm in high speed wireless networks since the proposed algorithm has low computational complexity,is simple to implement,and has the ability to handle channel errors.

Sensor operation in harsh environments up to 1000C requires robust packages including stable electrodes and protective coatings. We have developed nanostructured ultra-thin (2 electrode structures grown by e-beam co-evaporation that operate at temperatures approaching 1000C. X-ray diffraction (XRD), resistivity, and electron microscopy (EM) studies indicate incorporation of ZrO2 within the film delays recrystallization, maintaining a stable morphology. We have also developed ultra-thin (2/N2/Ar mixtures. The SiAlON films are amorphous and extremely smooth (

This paper proposes an unsupervised approach to automatically interpret noun compounds using semantic similarity. Our proposed unsupervised method is based on obtaining a large amount of robust evidence for NC interpretation. In order to obtain evidence sentences for semantic relations (SRs), we first acquired sentences containing both a head noun and its modifier in the form of SR defi-nitions. Then we determined the semantic relations represented in the sentences by looking at the nouns in the test instances (noun mapping) and verbs in the SR definitions (verb mapping). In the noun mapping, we measured the similarity between nouns in test instances and nouns in the collected sentences. In the verb mapping, we mapped the verbs of sentences onto those in the SR definitions. Finally, we built a statistical classifier to interpret noun compounds and evaluated it over 17 SRs defined in [1].

Demodulate-and-forward (DmF) is an attractive approach when using cooperative diversity schemes in networks where only nodes with strict complexity constraints are allowed,such as sensor networks. In using DmF,the relay only demodulates,but does not decode,the received signal from the source node. Coding can be used at the relay to improve the performance over the relay-destination link. In unrelated work,relay selection has been shown to achieve full diversity order with low overhead by choosing the best relay node out of a pool of available relays to assist the source. A simple heuristic scheme for relay selection while using DmF is available,but this involves the exchange of channel parameters between the nodes,hence increasing the overhead. In this paper,we propose the use of the Bhattacharyya parameter (BP) to facilitate relay selection. The use of BP has the distinct advantage of incorporating the specific coding scheme used while retaining low computation load. As illustrated in our simulation results,the use of BP provides frame error rates quite similar to that obtained from exhaustive search. We should note that this BP-based relay selection scheme can also be applied to cooperation schemes where decoding is performed at the relay.
