Temperature Dependent Robust Control Of Hard Disk Drives Using Parameter Varying Techniques
… tracks that are less than 100 nm wide. Modern HDDs use a dual-state actuator to position the transducer onto these tracks. Since the tracks are extremely narrow, a high performance controller is required to reject disturbances from various sources and maintain the position of the transducer on …

Household food security and dietary diversity in the context of an agricultural and market development program in Guatemala
… food security (ELCSA), and dietary diversity (HDDS) in 372 households (271 P4P; 101 control) using a cross-sectional design and mixed-methods. Most Significant Change (MSC) methodology was used to characterize participants' experiences in a subset sample of 57 households (46 P4P; 11 control). …

The role of heat assisted magnetic recording in future hard disk drive applications
… market for ultrahigh areal density HAMR-based HDDs. HAMR-based HDD for portable applications could very well be a disruptive technology in the magnetic recording industry. Companies that intend to profit from this technology need to invest on its development and must try to be first-to-volume …

Constraining a historical black carbon emission inventory of the United States from 1960-2000
… pattern over 1960-2000. Heating Degree Days (HDDs) data are applied to estimate seasonal residential emissions. However, even the adjustment for HDDs does not fully explain the trend in seasonal variation of the measurement. Also, the mismatch of modeled BC and measurement in New Jersey …

Disturbance attenuation with multi-sensing servo systems for high density storage devices
… in magnetic recording demonstrations for future HDDs (Hard-Disk Drives) are projected to exceed 500,000 TPI (Tracks-Per-Inch) in the year 2007 and are still increasing. However due to the renowned superparamagnetic limitation in magnetic recording physics, data storage industries are also looking …

Factors affecting the food security status and participation in food security intervention programmes in Maphumulo
… security, the Household Dietary Diversity Score (HDDS) and Household Food Consumption Score (HFCS) measures were employed. Food consumption pattern were characterized by a low average HDDS of 3.1 in “One Home One Garden” group and 3.67 in non- participating households. However, the majority (65%) …

Design of a permanent magnet generator for a sustainable wind energy capture and storage system
… magnets (PMs) from discarded hard disk drives (HDDs). The PM configuration inherently produces a non-uniform air gap flux-density distribution and the pole pitches of the PMs are relatively small. This would result to an unbalanced generator output and a number of stator inter-connecting leads, …

An investigation of the relationships among homegardens, dietary diversity, and the nutritional status of children aged 0 to 5 in Indian households
… of homegardens too. Household dietary diversity (HDDS) is positively associated with the household crop diversity and presence of homegardens in the household. The results of this study show that the short term nutritional status weight-for age scores (WAZ) of children in the ages 0 to 5 is …

Rethinking Update-in-Place Key-Value Stores for Modern Storage
… for the performance characteristics of HDDs, LSMs provide good write performance by emphasizing sequential access to storage. However, this approach negatively impacts read performance: LSMs must employ expensive compaction jobs and memory-consuming Bloom filters in order to achieve …

Factors Contributing to Child Malnutrition in the Informal Settlement of Inanda Area, eThekwini Municipality.
… households were severely food insecure. The HDDS analysis showed that most child caregivers’ households had low dietary diversity (deemed food insecure). Where cereal roots and fat foods were the main dietary components. A greater proportion of child caregivers’ households had no water and …

Geometrical control of domain walls and the study of domain wall properties of materials with perpendicular magnetic anisotropy
Magnetic based devices such as hard disk drives (HDDs) are widely used in the computer industry because of their high memory capacity, non-volatility and low cost compared to semiconductor-based solid state disk drives (SSDs). However, they also suffer from low energy efficiency and low speed, due …

Smallholder agriculture and food and nutrition security: a study from south-eastern Tigray, Ethiopia
Smallholder agriculture is the mainstay of the economy of Tigray, northern Ethiopia. Households located in the food insecure south-eastern zone rely on agriculture for their livelihood. Supplementary income is obtained from a range of off/non-farm activities. Households in the area consume a …
