As Koizumi (2000) and Fukui and Sakai (2006) observe, however, “multiple long-distance scrambling” improves significantly if the scrambled element forms an intonational phrase, though we rather argue that the relevant phonological phrase is not an intonational phrase but a major phrase (aka “intermediate phrase”). The boundary of a major phrase is often marked by a pause or glottalization. The ...
We explore the possibility of accounting for scrambling patterns in German using multidimensional grammars. The primary desirable characteristic of this approach is that it employs elementary structures with a single uniform component and combining operations which operate at a single point in the derived structure. As a result, we obtain an analysis that is much closer in spirit to ordinary TA...

For the two last decades, people have tried to provide practical electronic cash schemes, with more or less success. Indeed, the most secure ones generally suffer from inefficiency, largely due to the use of restrictive blind signatures, on the other hand efficient schemes often suffer from serious security drawbacks. In this paper, we propose both a new tool providing scalable anonymity at a l...
At present, the existing single-pixel position-scrambling technique is not sensitive to chaotic sequence used, and adjacent-pixel position scrambling has difficulty ensuring a good effect speed at same time. In this paper, stage-merging algorithm proposed, which combines two-stage process can complete dual of pixel value It only improves speed, but also greatly effects. Then, image encryption d...
A novel image encryption method is proposed by utilizing random phase encoding in the fractional Fourier domain to encrypt two images into one encrypted image with stationary white distribution. By applying the correct keys which consist of the fractional orders, the random phase masks and the pixel scrambling operator, the two primary images can be recovered without cross-talk. The decryption ...
Korean Combinatory Categorial Grammar (KCCG) is an extended combinatory categorial grammar formalism that can capture the syntax and interpretation of the \relative free" word order, long distance scrambling and other characteristics of Korean. The KCCG formalism can uniformly handle word order variation among arguments and adjuncts within a clause as well as in complex clauses and across claus...
Peak to average Power Ratio (PAPR) is the major drawback of orthogonal Frequency Division Multiplexing (OFDM) systems. Since OFDM is the indispensable technology for 4G wireless schemes, great attention is given to PAPR reduction. Some of the techniques classified under signal distortion and signal scrambling already existing to meet the needs, but their effectiveness is still a question for re...
