The thesis of this paper is that in the digital age we are moving away from words and concepts characteristic print age, towards use images symbols. I distinguish between objective symbols as mathematics, cultural poetry religion. Students must learn to move recognizing rules language internalizing norms culture, according analogy learning. Ricoeur’s theory interpretation explains passage recog...

Past research has examined the contribution of mediator-based encoding strategies (interactive imagery and sentence generation) to individual (particularly age-related) differences in associative memory exclusively in the paired-associates paradigm. In the present study, we examined young and older adults' mediator-based strategy use on source-monitoring tasks. Participants spontaneously used m...

The beta-2 adrenergic receptor (β2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with (binds) epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via a downstream Ltype calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation. Unlike other adr...

In this paper we consider noncoher ent multi symbol detection of factor graph codes over Rayleigh fading channels We use block di erential encoding together with a joint demodulation and it erative decoding algorithm to eliminate the pilot over head required for coherent detection Simulations us ing turbo codes and repeat accumulate codes show that as the length of the coherence interval increa...

the subject of womanhood is an attempt to explain why the woman is a symbol of self. i will start the paper with the story of “a’arabi and the caliph” from the view point of symbol and then i will continue with the definition of self, symbol, why the woman is a symbol of self as it is believed by mystics. the allegorical result based on najm razi’s theory shows the accompaniment of self with wi...

We present an unsupervised learning algorithm that acquires a natural-language lexicon from raw speech. The algorithm is based on the optimal encoding of symbol sequences in an MDL framework, and uses a hierarchical representation of language that overcomes many of the problems that have stymied previous grammar-induction procedures. The forward mapping from symbol sequences to the speech strea...

Lossy JPEG compression is a widely used compression technique. Normally the JPEG standard technique uses three process mapping reduces interpixel redundancy, quantization, which is lossy process and entropy encoding, which is considered lossless process. In this paper, a new technique has been proposed by combining the JPEG algorithm and Symbol Reduction Huffman technique for achieving more com...

Pattee's semantic closure principle is used to study the characteristics and requirements of evolving material symbols systems. By contrasting agents that reproduce via genetic variation with agents that reproduce via self-inspection, we reach the conclusion that symbols are necessary to attain open-ended evolution, but only if the phenotypes of agents are the result of a material, self-organiz...

Energy consumption has risen to be a bottleneck in wireless sensor networks. This is caused by the challenges faced these networks due their tiny nodes that have limited memory storage, small battery capacity, processing capability, and bandwidth. Data compression been used reduce energy improve network lifetime, as it reduces data size before can forwarded from sensing node sink network. In th...

A pattern-based cognitive communication system (PBCCS) that optimizes non-periodic RF waveforms for security applications is proposed. PBCCS is a cross-layer approach that merges the channel encoding and modulation. The transmitter encodes sequences of bits into continuous signal patterns by selecting the proper symbol glossaries. The cognitive receiver preprocesses the received signal by extra...
