Adaptive Cache Allocation with Prefetching Policy over End-to-End Data Processing

Hang Qin, Li Zhu
2017 Journal of Signal and Information Processing  
Also, through the instruction cache and the failure behavior for the data cache, a prefetching policy is developed, which is combined with the data capture of the failover queue state.  ...  This scheme can make full use of the characteristics of stack space data access, adopt fast address calculation strategy, and reduce the hit time of stack access.  ...  There are two ways to deal with the data in the high-level memory location, one is a simple replacement of the original cache data, the other is to increase a certain amount of storage unit.  ...

The Implications of Visualization Ability and Structure Preview Design for Web Information Search Tasks

Honggang Zhang, Gavriel Salvendy
2001 International Journal of Human-Computer Interaction  
Structure preview is a Web site navigation menu in which each menu item serves as a link to one Web page, similar to a menu design in Microsoft Windows 95 and Windows 98.  ...  A human-centered design-structure preview-was proposed in this study.  ...  Because this was a two-factor factorial design, a two-way analysis of variance (ANOVA) was run for both variables.  ...

A Social-based Strategy for Memory Management in Sensor Networks

Basim Mahmood, Ronaldo Menezes
2016 Proceedings of the 5th International Confererence on Sensor Networks  
In this paper, we propose a novel social-based strategy for memory management in mobile sensor networks.  ...  This strategy is inspired from two concepts, namely, social capital in sociology and preferential return mechanism in human mobility.  ...  For a better understanding of how AS strategy works, a scenario is considered as follows: SCENARIO: Consider A is a device in the environment with maximum allowable items that can be stored in its memory  ...

Browsing while reading: effects of instructional design and learners' prior knowledge

Thiemo Müller-Kalthoff, Jens Möller
2006 Research in Learning Technology  
Thirty-six university students worked through a hierarchically structured two-part hypertext about the psychology of memory under two experimental browsing conditions (reduced versus free browsing).  ...  Results show that deeper-level comprehension (i.e. structural knowledge) was predicted by the interaction of experimental condition and prior knowledge, but that simply retaining facts was not.  ...  Figure 2 shows an example of a typical content page from the hypertext environment.  ...
