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.

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...

We study a reaction-diffusion model that describes the growth and spread of a species along a shifting habitat gradient on which the species’ growth increases. It is assumed that the linearized species growth rate is positive near positive infinity and is negative near negative infinity. We show that the persistence and spreading dynamics depend on the speed of the shifting habitat edge c and a...

Spreading of a conservative solute in potential flow in a helical porous medium is dominated by the radial velocity distribution within the domain. Higher velocities at the inside of the helix compared to the outside leads to spreading that is balanced by transverse pore-scale dispersion. The angular moments of the concentration distribution exhibit the typical behavior of Taylor-Aris dispersio...

Dynamic diffusion MRI was used to visualize hyperacute stroke formation in the brain of a cynomolgus macaque. Under fluoroscopic guidance, a microcatheter was placed into the middle cerebral artery (MCA). The animal was immediately transferred to a 1.5T clinical scanner. Dynamic T2-weighted imaging during bolus injection of Oxygen-17 enriched water through the microcatheter mapped out the terri...

Horizontal dispersion in the surface waters of a medium-sized lake was investigated based on four experiments with ensembles of 14 to 17 drifters deployed in Lake Constance during the winter season. The experiments cover length scales between 30 and 3000 m which are typical for the grid length scales employed in 3-D models. Horizontal dispersion coefficients Kdisp were estimated to range from 0...

cortical spreading depression (csd) are associated with dramatic failure of brain ion homeostasis, efflux of excitatory amino acids from nerve cells, increased energy metabolism and changes in cerebral blood flow. there is strong clinical and experimental evidence to suggest that csd is involved in the mechanism of migraine, stroke, subarachnoid hemorrhage and traumatic brain injury. therefore,...

objective headache is a frequent symptom in children and adolescents. migraine is one of the most common types of primary headache disorders in children that at times can be extremely disabling. many clinical features of migraine in children differ from that starting in adulthood. this review discusses the epidemiology,clinical features, management, and prognosis of migraine headache in childre...

Results of cognitive psychology research are analysed to explain why it is diicult for retrieval system users to bring to mind alternative search terms. A human memory model is modiied in such a way that it produces additional search terms instead of human associations. A small experiment shows that such a spreading activation network can nd alternative terms-with a performance similar to the n...
