This paper proposes a new reversible data hiding scheme for encrypted images by using homomorphic and probabilistic properties of Paillier cryptosystem. The proposed method can embed additional data directly into encrypted image without any preprocessing operations on original image. By selecting two pixels as a group for encryption, data hider can retrieve the absolute differences of groups of...

A. Winman, P. Wennerholm, and P. Juslin (2003) have admitted that J. K. Kruschke (2001a) cogently demonstrated the shortcomings of eliminative inference as an explanation of the inverse base rate effect, but they raise criticisms of Kruschke’s attentionally based explanation. First, Winman et al. pointed out that attentional shifting does not improve learning performance in Kruschke’s (1996) AD...

For the polypentapeptide of elastin, (L-Val-L-Pro-Gly-L-Val-Gly)n, and appropriate analogs when suitably cross-linked, it has been previously demonstrated that development of elastomeric force at fixed length and length changes at fixed load occur as the result of an inverse temperature transition, with the temperature of the transition being inversely dependent on the hydrophobicity of the pol...

This paper proposes a new model for null subjects, and focuses on its implications for language development. The literature on pro-drop generally considers that not allowing null subjects is, informally speaking, the "default" option in natural languages, and appeals to particular morphosyntactic mechanisms in order to account for those languages in which the subject can be omitted. Shifting th...

This paper is part 2 in a series of papers about the Discrete Fourier Transform (DFT) and the Inverse Discrete Fourier Transform (IDFT). The focus of this paper is on a fast implementation of the DFT, called the FFT (Fast Fourier Transform) and the IFFT (Inverse Fast Fourier Transform). The implementation is based on a well-known algorithm, called the Radix 2 FFT, and requires that its' input d...

In this paper, a new peak-to-average power ratio (PAPR) reduction scheme for orthogonal frequency division multiplexing (OFDM) is proposed based on the selected mapping (SLM) scheme. The proposed SLM scheme generates alternative OFDM signal sequences by cyclically shifting the connections in each subblock at an intermediate stage of inverse fast Fourier transform (IFFT). Compared with the conve...

objectives: the attentional control scale is a self- report questionnaire that assesses individual differences in attentional control. despite its extensive use, the psychometric properties of the persian version of the acs are not well understood. thus, the present study aimed at investigating the psychometric properties of the attentional control scale and its relationship with symptoms of an...
