Because of the elastic service capability of cloud computing platform, more and more applications are moved here, which makes efficient load balancing into a bottleneck. Considering the unique features of long-connectivity applications which are increasingly popular nowadays, an improved algorithm is proposed based on the weighted least connection(More)
This paper describes extensions to a musical score indexing program that enable it to discover sequences of notes that appear in retrograde and/or inverted form. The program was tested over a set of 50 orchestral movements by several composers of the Baroque, Classical, and Romantic periods. The retrograde and inversion discovery algorithm added an average(More)
Cloud computing also known as on demand computing is cutting edge technology today and has gained much popularity in last few years due to rapid growth in technology and internet. Cloud computing provides software, platform and infrastructure as services over the internet which can be accessed using thin client like web browser on pay-per-use basis. With(More)
We propose an effective approach to automatically identify predicate heads in Chinese sentences based on statistical pre-processing and rule-based post-processing. In the pre-processing stage, the maximal noun phrases in a sentence are recognized and replaced by " NP " labels to simplify the sentence structure. Then a CRF model is trained to recognize the(More)
—An iterative carrier frequency offset (CFO) estimation method is proposed for the physical uplink control channel (PUCCH) of 3GPP-LTE in high speed train environment. In the algorithm, the signal of one user in the received multiuser signals is separated by despreading, and the despreaded pilot signals of the user are employed in the cross-correlation(More)
In order to solve the problem of Katakana reduced to English in Japanese-English translation, we employ the phrase-based statistical machine translation model to perform Katakana phrase (or word) translation from Japanese to English. The katakana phrase is segmented into words by CRF, and then Japanese-English and English-Japanese bi-directional integration(More)
