Nowadays, data security becomes a big issue and a challenge when sending sensitive data through the Internet. For example; sending user password, performing money transaction (e-business) using a master card, and invoking methods on a remote PC. All these activities require a secure algorithm for protecting data from hackers and thus keep information private and save. There are various methods for securing data when they are sent through the global network. Some of these techniques are based on data encryption algorithms where the text message is encrypted (scrambled) to another form that is not readable by humans. One of the encryption techniques is based on the transformation of a text into an image. In this paper, we propose a simple and a novel data encryption algorithm based on encrypting a text into a white page image (White-Page Image Encryption Algorithm or the WPI algorithm). In this paper, the proposed White-Page Image Encryption Algorithm is tested and analyzed.

This research illustrates the utilization of a new model based on artificial neural networks (ANNs) in prediction of compressibility factor (z-factor) of natural gases using experimental data based on Standing and Katz z-factor diagram. Although equations of state and empirical correlations have been applied for predicting compressibility factor, the demands for the modern, more reliable and easy-to-use models encouraged the researchers to recommend modern facilities such as intelligent systems. This investigation describes a new technique for computing z-factor of natural gases. The base of the approach is ANN in which a 2:5:5:1 structure is used as an optimum network to predict the z-factor. The statistical results show that the developed ANN is an excellent tool for estimating z-factor values; therefore, it can be confidently used for natural gases with various compositions at a specific temperature and pressure. © 2017 The Natural Computing Applications Forum

We introduce several new identities combining basic hypergeometric sums and integrals. Such identities appear in the context of superconformal index computations for three-dimensional supersymmetric dual theories. We give both analytic proofs and physical interpretations of the presented identities. © 2016 The Author(s)

CNT-water nanofluid flow over a stretching plate is examined considering heat generation and thermal radiation effects. Runge–Kutta scheme is utilized to solve the ODEs. Numerical investigation is completed by examining the various values of temperature index parameter, radiation parameter, heat generation parameter and velocity ratio parameter. Results indicated that temperature gradient augments with increase of temperature index parameter and velocity ratio parameter while it reduces with increase of heat generation parameter and radiation parameter. © 2017 Elsevier B.V.

Recently, it was realized that nonperturbative instanton effects can be generated to all orders by perturbation theory around a degenerate minima via the Dunne-Ünsal relation in several quantum mechanical systems. In this work we verify the Dunne-Ünsal relation for resonance energy levels of one-dimensional polynomial anharmonic oscillators. We show that the relation is applicable to cubic and quartic anharmonic oscillators which are genus-one potentials. However for higher order (higher genus) anharmonic potentials the relation is not satisfied and is subject to a certain extension. © 2016 American Physical Society.

ISSICEU analyses sources of stability and instability in the Caucasus regarding political regimes, civic participation, economic interdependencies and neighbourhood influences. We evaluate the implications for military, political, economic and societal security. We deliver three relevant products for EU policy formulation: We analyse and map emerging conflicts of local, regional and international dimensions and highlight crucial actors and mechanisms. We elaborate on scenarios concerning potential future security developments. We give concise policy recommendations on opportunities for the EU to influence conflict solution and long-term stability in the Caucasus societies and the whole region. ISSICEU disseminates the findings as follows: policy briefs; expert workshops in relevant EU agencies and for stakeholders in EU countries and the Caucasus; a scenario-workshop at the final stage. ISSICEU explores intra-societal frictions and their regional impact in the political regimes focussing mainly on dynamics of communal governance; the interplay of religious and state actors and practices of civic participation. We analyse inter-societal sources of (in)stability regarding economic dependencies; political and societal relations between the Caucasus and neighbourhood states. ISSICEU makes comparative analyses across sub-regions and studies aspects of inter-societal relations. We consider the historical and contemporary ties among the societies. We study the Caucasus in its diversity and cohesiveness. Cases are Armenia, Azerbaijan, Georgia, Abkhazia, South Ossetia, Nagorno-Karabakh, Dagestan, Kabardino-Balkaria, Karachay-Cherkessia and Chechnya. In the neighbourhood we focus on Turkey and Iran. ISSICEU takes theory-informed, interdisciplinary and strongly inductive approaches, able to adequately identify phenomena as they manifest themselves in the region and to give innovative policy recommendations.

There are not enough information about the fatigue characteristics of cold recycled mixes with bitumen emulsion and cement. In this research with the purpose of studying the fatigue characteristics of these mixes and determining the effects of different parameters, several laboratory recycled specimens containing CSS-1h bitumen emulsion and two types of cements (type I and I (PM) pozzolanic cement) have been prepared and tested. The main laboratory tests consisted of resilient modulus and indirect tensile fatigue test. After curing specimens in laboratory conditions, specimens were tested at three different temperatures and curing times. For each recycled specimen, studied parameters consisted of cement type, cement content, test temperature and curing time. According to obtained results, by increasing cement content and decreasing temperature, the slope of fatigue line will be decreased but no considerable change in fatigue behavior was occurred upon increasing the curing time. Furthermore, in comparison with reference specimens (i.e. specimens with no cement) and type I cement specimens, I (PM) cement had the mean fatigue behavior. At low initial strain levels, the fatigue life of I (PM) cement specimens were more than reference specimens and less than type I cement, whereas at high initial strain levels, the fatigue life of I (PM) cement specimens were more than type I cement and less than the reference specimens. © 2010 Elsevier Ltd.

Up to know, several methods have been developed to determine degree of N-acetylation, DA, for chitin and chitosan. In this article, an effort has been made to review the available literature information on the DA for the two biopolymers by different techniques of nuclear magnetic resonance, NMR (1H NMR, 13C NMR, and 15N NMR) spectroscopy. This article describes the effects of various parameters and different compounds as impurities of the original polymers (moisture, minerals, proteins, and pigments) on the accuracy of the DA values. This study allows one to choose an appropriate technique to determine the DA for the two polymers. These techniques have been compared for their performances and limitations. Among various NMR spectroscopy techniques, 1H NMR is the most sensitive and precise technique and results in the most accurate data. 13C NMR and 15N NMR techniques have been employed for entire range of the DA. © 2009 Elsevier Ltd.

Water is a major component of drinking water, beverages, and most foodstuffs. In this study, an effort has been made to employ selected properties of water for: (1) evaluation of interactions of water with other food components; (2) discussion on the effects of water properties on food and beverage products; (3) applications of water properties in food technology; and (4) comparison of water properties with corresponding properties of similar substances. This study provides the following major conclusions: (i) unusual properties of water are mostly due to its high permanent dipole moment, partial ionic character of O-H covalent bonds, and extensive hydrogen bonds; (ii) different properties of many foodstuffs are strongly related to various properties of water; (iii) the properties of food products change depending on water availability and temperature; (iv) preparation of drinking water is a prerequisite for production of any safe drinks and foodstuffs; (v) water contributes important roles in quality, flavor, and shelf-life of foods; and (vi) water is used in food industries as a fluid for heat transfer; as a medium for temperature moderation in food processing; as a solvent for sugars, salts, water-soluble vitamins, and acids; as a dispersing agent for hydrophilic food components; as a dispersed phase for emulsified products; or as a reactant for several reactions in food processing.
