Smart grid is a term referring to the next generation power grid in which the electricity distribution and management is upgraded by incorporating advanced two-way communications and pervasive computing capabilities for improved control, efficiency, reliability and safety. The smart grid is a network of networks, including a variety of sub-systems. One subsystem which is at the core of smart grid systems is the Supervisory Control And Data Acquisition (SCADA) solution. The objective of the paper is to develop a method uses a hybrid of the advanced Encryption Standard (AES) and the Elliptic Curve Cryptography (ECC) to Secure SCADA in Smart Grid. Because without a secure SCADA system it is impossible to deploy the intelligent smart grid systems. Read More Read Less

Abstract Semantic similarity measures are an important part in Natural Language Processing tasks. However Semantic similarity measures built for general use do not perform well within specific domains. Therefore in this study we introduce a domain specific semantic similarity measure that was created by the synergistic union of word2vec, a word embedding method that is used for semantic similarity calculation and lexicon based (lexical)... Semantic similarity measures are an important part in Natural Language Processing tasks. However Semantic similarity measures built for general use do not perform well within specific domains. Therefore in this study we introduce a domain specific semantic similarity measure that was created by the synergistic union of word2vec, a word embedding method that is used for semantic similarity calculation and lexicon based (lexical) semantic similarity methods. We prove that this proposed methodology out performs word embedding methods trained on generic corpus and methods trained on domain specific corpus but do not use lexical semantic similarity methods to augment the results. Further, we prove that text lemmatization can improve the performance of word embedding methods. Read More Read Less

Abstract A novel design of Seven band loop antenna for the frequency range from 0.7Ghz to 6Ghz covering all Wireless systems, is described and simulated.the antenna is planar inverted F, optimized using Particle swarm optimization with nonuniforms chromosome matrix to locate the slot on the resonator part of the PIFA.The optimized antenna is simulated by both software Ansoft HFSS and computer simulation technology microwave... A novel design of Seven band loop antenna for the frequency range from 0.7Ghz to 6Ghz covering all Wireless systems, is described and simulated.the antenna is planar inverted F, optimized using Particle swarm optimization with nonuniforms chromosome matrix to locate the slot on the resonator part of the PIFA.The optimized antenna is simulated by both software Ansoft HFSS and computer simulation technology microwave studio CST). The simulation result shows that both software are in good agreement and the antenna provide a minimal gain of 3dBi and a maximal gain of 7dBi. Read More Read Less
