We have created a show about the Solar System, freely available for both planetariums and home viewing, where objects in space are represented with sound as well visuals. For example, audience listens to stars appear above European Southern Observatory's Very Large Telescope they hear planets orbit around their heads. The aim of this is that it can be enjoyed understood, irrespective level visi...

this study sought to investigate the impact of teaching speech acts and role relations through authentic audio-taped and video-taped materials on the level of iranian efl learners’ pragmatic competence. to this end, 55 intermediate learners were ed and randomly assigned to two experimental groups: the audio-taped group and the video-taped group. during the treatment, the audio-taped group recei...

Image encryption is an active and challenging research area. This article proposes a transposing and scrambling image encryption algorithm based on improved hyper-chaotic sequence to provide enhanced security for encrypted image transmission. The algorithm processes the hyper-chaotic sequence according to the pixel information, which makes the keys be sensitive to original image. Then we apply ...

This article considers unbiased estimation of mean, variance and sensitivity level of a sensitive variable via scrambled response modeling. In particular, we focus on estimation of the mean. The idea of using additive and subtractive scrambling has been suggested under a recent scrambled response model. Whether it is estimation of mean, variance or sensitivity level, the proposed scheme of esti...

Bo'ković (2004) argues that what defines scrambling in languages such as Japanese is its ‘‘undoing’’ property (Saito 1989). Bo'ković (2004) and Bo'ković and Takahashi (1998) argue that this ‘‘undoing’’ property shows the way for scrambling to count as a last-resort operation, instead of being purely optional as is widely believed. In this article, I give empirical evidence that ‘‘undoing’’ does...

Existing analyses of German scrambling phenomena within TAG-related formalisms all use non-local variants of TAG. However, there are good reasons to prefer local grammars, in particular with respect to the use of the derivation structure for semantics. Therefore this paper proposes to use local TDGs, a TAG-variant generating tree descriptions that shows a local derivation structure. However the...

We present a theoretical analysis of one-time key based phase scrambling for image matching using phase-only correlation (POC). Phase scrambling is used for visual information protection of templates. The effect of scrambling on POC values is analyzed. As a result, the peak value, which is used as a measure of signal congruence, of the POC between nonscrambled signals can be estimated by observ...
