This paper reduces the delay in wireless transmission of electrocardiogram (ECG) data while protecting their essential elements to produce a clinically usable trace. The ECG data are divided into nine layers according to the signal amplitude resoluti

Application launch times can be reduced by using low-capacity solid-state drives (SSDs) in combination with the conventional magnetic hard disk drives (HDDs). We propose a storage tiering scheme for a logically integrated hybrid disk that eliminates

Data generation rates of sensors are rapidly increasing, reaching a limit such that storage expansion cannot keep up with the data growth. We propose a new big data archiving scheme that handles the huge volume of sensor data with an optimized lossy

The quality-adjustable nature of sensor data and gradually decreasing access pattern foster a new data archiving scheme that can cope with rapidly increasing data generation rates by sensors. We propose a scalable quality management of massive sensor

Application loading speed can be improved by timely prefetching disk blocks likely to be needed by an application. However, existing prefetchers -- if they are not specialized to a particular application -- incur high overheads and are poor at identi

Active storage devices further improve their performance by executing “intelligence functions,” such as prefetching and data deduplication, in addition to handling the usual I/O requests they receive. Significant research has been carried out to

BACKGROUND AND PURPOSE: High-resolution MR imaging can depict intracranial arterial atherosclerotic plaques. Our aim was to evaluate the relationship between the degree of enhancement of MCA plaques on contrast-enhanced high-resolution MR imaging and

We propose a code scratchpad memory (SPM) management technique with demand paging for embedded systems that have no memory management unit. Based on profiling information, a postpass optimizer analyzes and optimizes application binaries in a fully au

Various broadcast schemes have been proposed to reduce the data access time of mobile clients. However, they are based either on the mobile users' data access frequencies or on the semantic relations of the data. In this paper, we present a hybrid da

An efficient mobile video streaming system needs to cope with unstable network bandwidth and limited battery life. We propose a novel streaming system which jointly considers picture quality, bit-rate and energy consumption. Reducing the spatial reso
