Abstract

The viscosity of bitumen is extremely high at ambient temperature and in order to produce and transport the bitumen, it is necessary to reduce its viscosity. In this regard various n-alkane with different surface tension dilutes bitumen. This study features the application of artificial neural network for prediction of surface tension of branched alkanes. Modeling results showed that the both models are accurate and effective in prediction of surface tension of branched alkanes. However, the results were compared with experimental data and it was found that the estimated surface tension by ANN-MLP is more accurate than radial basis function network. [ABSTRACT FROM AUTHOR]

Abstract

A compressed Qubits image steganography based on an optimized adaptive neural networks is proposed in this paper, to solve many problems related to adjustment, size and recognition. that are considered inefficient in image information concealing. We used M-PSO algorithm to determine an optimal target vales of the adaptive neural networks to obtain low noise and high accuracy when the results trained. However, our proposed scheme can separately conceal secret message and the content of cover file.

164. EEIRI: Efficient Encrypted Image Retrieval in IoT-Cloud.

Abstract

One of the best means to safeguard the confidentiality, security, and privacy of an image within the IoT-Cloud is through encryption. However, looking through encrypted data is a difficult process. Several techniques for searching encrypted data have been devised, but certain security solutions may not be used in IoT-Cloud because such solutions are not lightweight. We propose a lightweight scheme that can perform a content-based search of encrypted images, namely EEIRI. In this scheme, the images are represented using local features. We develop and validate a secure scheme for measuring the Euclidean distance between two descriptor sets. To improve the search efficiency, we employ the k-means clustering technique to construct a searchable tree-based index. Our index construction process ensures the privacy of the stored data and search requests. When compared with more familiar techniques of searching images over plaintexts, EEIRI is considered to be more efficient, demonstrating a higher search cost of 7% and a decrease in search accuracy of 1.7%. Numerous empirical investigations are carried out in relation to real image collections so as to evidence our work. [ABSTRACT FROM AUTHOR]

180. Using E-Connection and Description Logic for Formalizing and Analyzing High-Level Petri Net

Abstract

High-level Petri net has been used by more and more researchers for its high-level formalism. In order to facilitate the interoperability between different researchers and tools, we propose a novel logical approach, which is based on description logic and epsiv-connection, to formalizing and analyzing high-level Petri net (HLPN). First, HLPN-ontology (high-level Petri net ontology) is partitioned into algebra-ontology and structure-ontology for reuse and easy analysis. Then, algebra-ontology and structure-ontology are combined with epsiv-connection to express HLPN-Ontology in a compact way. The result of money changing service experiment, which is represented with high-level Petri net, shows that it is more efficient to analyze high-level Petri net with the approach discussed in this paper. The effect of using description logic and epsiv-connection is better than that of using Petri net markup language (PNML), which is an XML-based interchange format but it is not machine-processable.

Abstract

Recently, Zhang and Lu provided a quantum search algorithm based on partial adiabatic evolution, which beats the time bound of local adiabatic search when the number of marked items in the unsorted database is larger than one. Later, they found that the above two adiabatic search algorithms had the same time complexity when there is only one marked item in the database. In the present paper, following the idea of Roland and Cerf [Roland J and Cerf N J 2002 Phys. Rev. A 65 042308], if within the small symmetric evolution interval defined by Zhang et al., a local adiabatic evolution is performed instead of the original “global one, this “new algorithm exhibits slightly better performance, although they are progressively equivalent with M increasing. In addition, the proof of the optimality for this partial evolution based local adiabatic search when M = 1 is also presented. Two other special cases of the adiabatic algorithm obtained by appropriately tuning the evolution interval of partial adiabatic evolution based quantum search, which are found to have the same phenomenon above, are also discussed.
