High-speed scanning in human memory.

چکیده
When subjects judge whether a test symbol is contained in a short memorized sequence of symbols, their mean reaction-time increases linearly with the length of the sequence. The linearity and slope of the function imply the existence of an internal serial-comparison process whose average rate is between 25 and 30 symbols per second.

Design of a Multiplier for Similar Base Numbers Without Converting Base Using a Data Oriented Memory
One the challenging in hardware performance is to designing a high speed calculating unit. The higher of calculations speeds in a computer system will be pointed out in terms of performance. As a result, designing a high speed calculating unit is of utmost importance. In this paper, we start design whit this knowledge that one multiplier made of several adder and one divider made of several su...

متن کاملScanner Detection Based on Connection Attempt Success Ratio with Guaranteed False Positive and False Negative Probabilities
Since the link rate is very high up to 40Gbps these days, scanning packets can spread very fast. At this high speed, only a small chance of missing on-going scanning activity can lead to catastrophic results. Thus, fast and accurate detection of scanners is a very important problem. High-speed packet processing usually requires high-speed memory, SRAM, and the size of SRAM is very limited compa...
متن کاملExamining the link between information processing speed and executive functioning in multiple sclerosis.
Slowed information processing speed (IPS) is frequently reported in those with multiple sclerosis (MS), and at least 20% are compromised on some aspect of executive functioning also. However, any relationship between these two processes has not been examined. The Sternberg Memory Scanning Test, Processing Speed Index (WAIS-III), Delis Kaplan Executive Function System (D.KEFS), and Working Memor...
متن کاملEffects of alpha-mangostin on memory senescence induced by high glucose in human umbilical vein endothelial cells
Objective(s): Hyperglycemia induces cellular senescence in various body cells, such as vascular endothelial cells. Since the vessels are highly distributed in the body and nourish all tissues, vascular damages cause diabetes complications such as kidney failure and visual impairment. Alpha-mangostin is a xanthone found in mangosteen fruit with protective effects in met...
