We apply genetic algorithms to Hop eld's neural network model of associative memory. Previously, using ternary chromosomes, we successfully evolved both random weight matrix and over-loaded Hebbian weight matrix to function as an associative memory. In this paper, we present a real-encoded genetic algorithm to evolve random synaptic weights to store some number of patterns as associative memory...

aim and background: one of the most important learning disabilities is spelling learning disability which is accompanied by memory problems and social skills. the main aim of present research was to review the effectiveness of cognitive-behavioral play therapy on memory and social skills of children with spelling learning disability. methods and materials: the research method of present study w...

objective: the present study aimed to compare prospective and retrospective memory impairment and attention deficit in people suffering from chronic low back pain with those cognitive functions in healthy subjects. furthermore, this study examines the relation between severity and duration of pain and prospective and retrospective memory impairment and attention deficit. methods: the research w...

lithium is a drug used for the treatment of bipolar disorder. it has several mechanisms of action, and recently it is shown that lithium can antagonize the 5-ht1b/1d serotonin receptors. sumatriptan is a 5-ht1b/1d receptor agonist used for the treatment of cluster headaches and migraine which might cause memory impairment as a potential side effect. in this study, effects of lithium on sumatrip...

Recently, Larrabee proposed a sequential test generation algorithm for combinational circuits based on boolean satisfiability and presented results on benchmark circuits in support of the viability of this approach. Parallel implementations of test generation algorithms are attractive in view of the known difficulty (NP-completeness) of the problem. In this paper we suggest parallel versions of...

Ternary content addressable memory (TCAM) is one key component in high-performance networking applications. An asymmetric TCAM cell consists of a binary content addressable memory (BCAM) bit and a mask bit. In this paper, we analyze comparison faults of the asymmetric TCAM cell based on BCAM comparison faults. Then march-like test algorithms T are proposed to cover the comparison faults of the ...

objectives: the purpose of this research was to explore the possible differences in the working memory of monolingual (persian) and bilingual  (persian-baluchi) children. we wanted to examine if there is a statistically significant relationship between working memory and bilingualism. methods: four working memory (wm) tests, assessing three wm components, were administered to 140 second grade s...

Blowfish algorithm is a block cipher algorithm, its strong, simple algorithm used to encrypt data in block of size 64-bit. Key and S-box generation process in this algorithm require time and memory space the reasons that make this algorithm not convenient to be used in smart card or application requires changing secret key frequently. In this paper a new key and S-box generation process was dev...
