The technology and cost barrier of the SSD motivated many research groups and companies to merge the SSD with low cost and large capacity storage device, Hard Disk Drive (HDD). As the NAND flash memory technology is getting more advanced, price of NAND flash memory dropped dramatically. As number of bits per cell in NAND flash memory is increasing, the price of $/GByte is reduced. This trend wi...

The relationship between precipitation deficits and extreme hot temperatures has been documented in observation and modeling studies. However, it is unclear whether and how increases in maximum temperatures will impact diurnal temperature range (DTR) extremes. Here, we used observational data sets from meteorological stations in China to examine the trends in high DTR extremes from 1971 to 2013...

This paper focuses on I/O optimizations of N-hybrid (New-Form of hybrid), which provides a hybrid file system space constructed on SSD and HDD. Although the promising potentials of SSD, such as the absence of mechanical moving overhead and high random I/O throughput, have drawn a lot of attentions from IT enterprises, its high ratio of cost/capacity makes it less desirable to build a large-scal...

Floating operation is very critical in power management in hard disk drive (HDD), during which no control command is applied to the read/write head but a fixed current to counteract actuator flex bias. External disturbance induced drift of head may result in interference of head and bump on the disk during drifting, leading to consequent scratches and head degradation, which is a severe reliabi...

One performance bottleneck of distributed systems lies on the hard disk drive (HDD) whose single read/write head has physical limitations to support concurrent I/Os. Although the solid-state drive (SSD) has been introduced for years, HDDs are still dominant storage due to large capacity and low cost. This paper proposes a caching middleware that manages the underlying heterogeneous storage devi...

OBJECTIVE To improve nutrition of malnourished children in the community, using home based treatment. METHODS A prospective cohort study was conducted in a squatter settlement of Karachi (Khuda Ki Basti). The study was conducted from August 2006 to March 2007. All children <5 years who were <-3sd weight for height were included as per WHO guidelines. After initial screening for complications,...

In today's data-driven business landscape, maintaining the resilience of digital infrastructure is paramount. One most critical components this hard disk drive (HDD). The potential for HDD failures poses a significant risk to data integrity and operational continuity. To address challenge, paper presents an innovative approach enhancing through predictive analysis using machine learning techniq...

Background: Malnutrition among under-five children is one of the paramount public health concerns in country. Objectives: This study aimed to determine relationship between nutritional status and household dietary diversity (HDD) food security (HFS). Methods: In this cross-sectional analysed 808 children’s data from 50 villages five divisions Sarawak using a multistage cluster sampling techniqu...

The interdependence between magnetization and charge transport is not a new story. For instance, anisotropic magnetoresistance (AMR), which links the value of the resistance to the respective orientation of magnetization and current, was first observed in 1856 by William Thomson, but its amplitude is weak (up to a few per cent variation in resistance on changing the relative orientation of magn...
