Due to the explosive increases of data from both the cyber and physical worlds, the demand for database support in embedded systems is increasing. Databases for embedded systems, or embedded databases, are expected to provide timely in-situ data services under various resource constraints, such as limited energy. However, traditional buffer cache management schemes, in which the primary goal is...

Working memory (WM) is a buffer that temporarily maintains information, be it visual or auditory, in an active state, caching its contents for online rehearsal or manipulation. How the brain enables long-term semantic knowledge to affect the WM buffer is a theoretically significant issue awaiting further investigation. In the present study, we capitalise on the knowledge about famous individual...

Classical buffer replacement policies, e.g., LRU, are suboptimal for database systems having flash disks for persistence, because they are not aware of the distinguished characteristics of those storage devices. We present CFDC (Clean-First Dirty-Clustered), a flash-aware buffer management algorithm, which emphasizes that clean buffer pages are first considered for replacement and that modified...

Volume holographic storage combines fast, parallel readout (because each hologram stores a large data page) with high density (because many holograms are multiplexed within the same volume). Phase-conjugate readout has been proposed as a way to eliminate the precision optics that recent demonstrations have relied upon to image the pixels of the input spatial light modulator (SLM) onto those of ...

DESIGNS FOR AN MPEG VIDEO CODER Y S Saw J M Hannah P M Grant Electrical Engineering, University of Edinburgh, Scotland Abstract In MPEG video encoding, e cient bu ering and rate control is especially crucial for constant bit rate (CBR) applications such as non-ATM (Asynchronous Transfer Mode) channels and satellite communication channels. In a CBR environment, compressed video data, which is in...

Blood samples are used as a biological source to discover biomarkers of hematological and non-hematological disorders. The present study shows the impact of different experimental conditions associated with cell lysis buffer, TRI-reagent protocol and blood cell storage buffer and their correlation with the quantity, quality and Adrenomedullin gene expression levels of total RNA when RT-PCR tech...
