Initially the infinitesimal generators and symmetry reduction, which were obtained by applying the Lie group method on the negative-order Kadomtsev–Petviashvili equation, have been used for constructing the reduced equations. In particular, the traveling wave solutions for the negative-order KP equation have been derived from the reduced equations as an invariant solution. Finally, the extended improved (G′/G) method and the extended tanh method are described and applied in constructing new explicit expressions for the traveling wave solutions. Many new and more general exact solutions are obtained.

A major challenge is handling and processing enormous amount of data and images for either image storage, data transfer, or image analysis. To help address this challenge, this study explores and proposes image compression techniques using non-adaptive linear interpolation and wavelet transform algorithms. The effect and implication of image compression are investigated in the close-range photogrammetry as well as in realistic structural health monitoring applications. For this purpose, images and results from three different laboratory experiments and three different structures are utilized. The first experiment uses optical targets attached to a sliding bar that is displaced by a standard one-inch steel block. The effect of image compression in the photogrammetry is discussed and the monitoring accuracy is assessed by comparing the one-inch value with the measurement...

This study aims to treat the tramadol hydrochloride (TH) in different water resources in Egypt. The identification and quantification of TH was explored using LC/MS/MS instrument. The study proposed kaolinite/ZnO nanocomposite (K/ZnO) as a new solution for TH treatment. The characterization study showed that the highest photodegradation activity was achieved in the case of K/ZnO40%. The photodegradation kinetics and thermodynamics are investigated. The obtained results reveal that Pseudo-first order model is well fitted with a correlation coefficient (0.990). Moreover, the positive values of ΔH˚ and ΔS˚ show that the photodegradation process is an endothermic reaction. Positive value of free energy indicates that the adsorption process is not spontaneous.

Nearly fifth of these accidents are caused by distracted drivers. Existing work of distracted driver detection is concerned with a small set of distractions (mostly, cell phone usage). Unreliable ad hoc methods are often used. In this paper, we present the first publicly available dataset for driver distraction identification with more distraction postures than existing alternatives. In addition, we propose a reliable deep learning-based solution that achieves a 90% accuracy. The system consists of a genetically weighted ensemble of convolutional neural networks; we show that a weighted ensemble of classifiers using a genetic algorithm yields a better classification confidence. We also study the effect of different visual elements in distraction detection by means of face and hand localizations, and s...

Although social networks have become a valuable resource for mining sentiments, there is no previous research investigating the layman's sentiment towards Spanish words of Arabic etymology related to Islamic terminology. This study aim at analyzing Spanish words of Arabic origin related to Islam. A random sample of 4586 out of 45860 tweets was used to evaluate general sentiment towards some Spanish words of Arabic origin related to Islam. An expert-predefined Spanish lexicon of around 6800 seed adjectives was used to conduct the analysis. Results indicate a generally positive sentiment towards several Spanish words of Arabic etymology related to Islam. By implementing both a qualitative and quantitative methodology to analyze tweets' sentiments towards Spanish words of Arabic etymology, this research adds breadth and depth to the debate over Arabic linguistic influence on Spanish vocabulary.

Hence, this paper traces some of these ideas in Ibn Taymiyya’s Khalq al-rūḥ, in which he asserts the soul’s origination rather than its eternity, so as to uphold the idea of God’s essence. This paper consists of two parts. Part I problematizes Khalq in light of previous research, presents the sources of the study, and addresses some concepts that are significant for appreciating the development of its main argument. The five major arguments that Ibn Taymiyya invokes to justify his viewpoint shall be reconstructed from Khalq. Likewise, some of the ambiguities surrounding his identification of those who hold opposite views shall be resolved. Part II provides an annotated translation of Khalq. İbn Kayyim’in meşhur eseri Kitâbu’r-Rûh akademik ilgiye konu olmasına rağmen, hocası İbn Teymiyye’nin ruhla ilgili görüşleri henüz incelenmemiştir. Bundan do...

Autoregressive integrated moving average (ARIMA) models are employed to benchmark evolutionary models. The results reveal that the GEP technique outperforms traditional statistical techniques in predicting oil prices. Further, the GEP model outperforms the NN and the ARIMA models in terms of the mean squared error, the root mean squared error and the mean absolute error. Finally, the GEP model also has the highest explanatory power as measured by the R-squared statistic. The results of this study have important implications for both theory and practice.

This paper presents a novel face representation that combines both shape and texture information for gender classification. We propose extracting the Scale Invariant Feature Transform (SIFT) descriptors at specific facial landmarks positions, hence encoding both the face shape and local-texture information. Moreover, we propose a decision-level fusion framework combining this Landmarks-SIFT with Local Binary Patterns (LBP) descriptor extracted for the whole face image. LBP is known of being tolerant against uncontrolled image capturing conditions. Competitive correct classification rates for both controlled (97% for FERET) and uncontrolled (95% and 94% for LFW and KinFace) benchmark datasets were achieved using our proposed decision-level fusion.

The consequences on selenoprotein biosynthesis of overexpressing either the wild type or a mutant tRNA(Ser)Sec lacking the modified base, isopentenyladenosine, in its anticodon loop were examined by introducing multiple copies of the corresponding tRNA(Ser)Sec genes into

Examination of these structures (I–VI) reveals that all possess an aromatic moiety and terminal amine binding sites (Glennon et al., J Med Chem 32(8):1921–1926, 1989). In the present investigation a new series of aryloxyalkylamines (4, 5, 8,
