RETRACTED ARTICLE: Psychological predictors behind the intention to drink and drive among female drivers: Application of extended theory of planned behavior
No full textWe, the Editor and Publisher of Traffic Injury Prevention, have retracted the following article: Ankit Kumar Yadav. Psychological predictors behind the intention to drink and drive among female drivers: Application of extended theory of planned behavior. Traffic Injury Prevention. 2020. https://doi.org/10.1080/15389588.2019.1703961. The author has requested the retraction of his article due to an error in one of the collected psychological measures. During data extraction, the responses for ‘attitude’ and ‘intention’ measures were switched and may have influenced the findings from the developed regression model and its results. As a result, the Editor and Publisher have agreed to retract the article in full. We have investigated and have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.</p

ABSTRACT
In this paper, we have suggested rectifications in differential cryptanalysis of ultra-lightweight block cipher PRESENT reduced to 16 rounds. We have shown that proposed differential attack by Wang [3] on 16 round PRESENT can recover at the most 30 subkey bits, although the author has claimed to recover 32 bits of subkey for last two rounds. We have also computed data complexity and success probability for recovering 30 subkey bits accordingly by the differential attack on 16 round PRESENT.

Tamper Localization Approach for Reversible Watermarking Algorithm Based on Histogram Bin Shifting
Get PDFReversible watermarking is a process which is used to authenticate the multimedia content. It checks the integrity of the digital data in order to recover the original data without any distortion. Industries like as medical services, military organization and legal services which are dealing the sensitive data where the minimal alteration is difficult to be tolerated is the application domain of Reversible watermarking. In this thesis, we have proposed a Tamper localization approach for histogram bin shifting based Reversible watermarking algorithm,where original image can be obtained from the watermarked image without any distortion. Tamper localization approach finds out the tampered region of the image, which is used for the selective rejection of the cover image. General application of reversible watermarking procedure says that the entire image gets rejected at receiver side due to the hash mismatch and authentication failure. By using our approach when the hash mismatch occurs the selected part of the image is rejected. This will reduce the re-transmission overhead on the communication channel and limited bandwidth is required due to small sub-part of re-transmission of the image. Here we are taking the advantage of the multiple minimum and maximum points of the histogram for embedding purpose. This will increase the embedding capacity. We have embedded the hash into smaller sub-part of the image until embedding is possible. The hash is generated through the some known cryptographic hash function such as SHA or MD5. This will help us to find out the tampered region at the receiver end while extracting the hash, in the case of hash mismatch occur in cover image which will lead to selective rejection of the cover images
Applicability of the Global Land Evaporation Amsterdam Model Data for Basin-Scale Spatiotemporal Drought Assessment
No full textDrought directly impacts the living organisms and environment, and thereby, its assessment is essential. Different drought indices require different data, which can be obtained based on models or in-situ measurements, demanding a significant amount of effort. Using remotely sensed (RS) data from satellites can facilitate this data acquisition. Nowadays, more and more satellite techniques are rising, highlighting the need to assess the accuracy of their data and the reliability of the results obtained by employing them. The Wet-environment Evapotranspiration Precipitation Standardized Index (WEPSI) has shown good performance in drought monitoring and assessment, especially for agricultural purposes. This chapter employs the Global Land Evaporation Amsterdam Model (GLEAM) data to investigate its applicability in the Lempa River basin drought assessment using WEPSI. In this order, evaluated data obtained from the Water Evaluation and Planning system (WEAP) were used as the basis for comparison. Precisely, a comparison was made with GLEAM and WEAP-based data as well as WEPSI time series based on these two datasets. The results show a relatively high similarity between these two datasets and calculated WEPSI drought indices. This validates the good performance of GLEAM-based data in drought monitoring and assessment based on WEPSI.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Water Resource

No full textEPR, optical absorption and superposition model studies of Cr3+
Get PDFElectron paramagnetic resonance (EPR) study of Cr3+ doped cesium tetrabromozincate (CTBZ) single crystal is done at room temperature. The hyperfine structure for Cr53 isotope is also obtained. Two magnetically inequivalent sites for Cr3+ are observed. The spin Hamiltonian parameters are evaluated as: D = 234×10-4cm-1, E = 69×10-4cm-1, g = 2.0104, A = 80×10-4 cm-1 for site I and D = 235×10-4 cm-1, E = 70×10-4cm-1, g = 2.0061, A = 82×10-4cm-1 for site II, respectively. The optical absorption spectra are recorded at room temperature. The energy values of different orbital levels are determined. The values of various parameters obtained are: B = 602 cm-1, C = 2504 cm-1, Dq = 1870 cm-1, h = 1.63 and k = 0.21, where B and C are Racah parameters, Dq is crystal field parameter, and h and k are nephelauxetic parameters, respectively. Theoretical zero-field splitting (ZFS) parameters for Cr3+ at two sites in CTBZ are evaluated using superposition model and microscopic spin Hamiltonian theory. The theoretical ZFS parameters are in good agreement with the experimental values
