This paper demonstrates a biologicallyand psychologicallyinspired human-like computational memory focusing on the retrieval mechanisms – Spreading Activation and Compound Cue for a companion agent’s episodic memory (EM) that helps the agent to manage it’s memory more efficiently and enable it to have a more natural interaction with the user.

This paper presents the analysis on the optimal settings of the spreading parameters of the spreading activation technique. The method is applied on the knowledge graph, an information representation technique that combines collaborative and content-based information. The evaluation of the recommendation technique is based on recommendation lists. The involved measures are precision, recall and...

Modelling interactions on complex networks needs efficient algorithms for describing processes a detailed level in the network structure. This kind of modelling enables more realistic applications spreading processes, metrics, and analyses communities. However, different real-world may impose requirements implementations their efficiency. We discuss transmission interrelations. Two pseudo-algor...

Recent information diffusion research has often focused on social networking sites like Facebook and Twitter, such as the analysis of reposting or hashtags as trends go “viral.” Partially due to its more private nature, email has been less popular of late. However, email’s near universal adoption as a means of online communication, its prevalence in commercial and academic environments, and the...

flood spreading has an effective role in the soil improvement and fertility, ground water storage, revival of vegetation and prevention of fluent sands movement. one of the main problem of flood spreading projects is the entrance of sediment to the spreading systems and sedimentation in it. sediment reduces the efficiency of the flood spreading system and after awhile lose its efficiency.the ma...

Spread spectrum systems are employed for the secure transmission of digital information which is achieved through spreading the signal in frequency domain. Pseudo-Noise (PN) sequences are conventionally used for this spectrum spreading and de-spreading process. However, the PN sequences are not truly random in nature and follow a deterministic pattern. Though the suitability of random sequences...

In this paper, we present a RF directional modulation technique using a switched antenna array for physical layer secure communication. The main idea is that a switching scheme of the switched antenna array is designed according to a spreading sequence for the purpose of spreading spectrum of the transmit signal. The transmit signal is associated with the spreading sequence and the direction of...

General definitions of spreading and coding are given based on the notion of Shannon bandwidth introduced by Massey (1994), with the goal of distinguishing these operations for signaling with bandwidth redundancy. These definitions are shown to lead to a separation result: every bandwidth redundancy scheme can be expressed as a concatenation of coding followed by spreading. The coding-spreading...
