The single core Energy Recovery Ventilator (ERV) used in this study is equipped with defrost control that recirculates the exhaust indoor air, while keeps outdoor air intake damper closed. This strategy has disadvantage of reducing supplied to house, which may affect quality. First, paper presents new correlation-based models supply temperature T 2 after energy recovery during normal and operat...

The electrical power consumed by typical magnetic hard disk drives (HDD) not only increases linearly with the number of spindles but, more significantly, it increases as very fast power-laws of speed (RPM) and diameter. Since the theoretical basis for this relationship is neither well-known nor readily accessible in the literature, we show how these exponents arise from aerodynamic disk drag an...

An adaptive feedforward controller design for tracking repeatable runout (RRO) in bit patterned media recording (BMPR) is proposed for single stage hard disk drives (HDD). The technique is based on modified filtered-x least mean squares (MFXLMS) algorithm with deterministic periodic input, and a novel variable step size that boosts both the convergence rate and the steady state error. Comprehen...

The interactive capability and ease of use of Geoweb technologies suggest great potential for Aboriginal communities to store, manage, and communicate place-related knowledge. For the Métis, who have a long history of dispossession and dispersion in Canada, the Geoweb offers an opportunity in realizing the desire to articulate a coherent sense of place for their people. This paper reports on a ...

One of the bottlenecks of distributed file systems (DFS), e.g. Google File System [1] and Hadoop Distributed File System [2], is mechanical hard disk drives (HDD): their slow increase in bandwidth, slow decrease in latency, and exponential increase in capacity, have made modern storage devices quite unbalanced. Making things worse, the low bandwidth and high latency of HDD hinders the explorati...

This paper proposes controller design methods, specially for track-following control of the magnetic read/write head in a hard disk drive (HDD). The servo system to be considered is a general dual-stage multisensing system, which encompasses most of the track-following configurations encountered in the HDD industry, including the traditional single-stage system. For the general system, a robust...

The drilling length is an important parameter in the process of horizontal directional drilling (HDD) exploration and recovery, but there has been a lack of accurate, automatically obtained statistics regarding this parameter. Herein, a technique for real-time HDD length detection and a management system based on the electromagnetic detection method with a microprocessor and two magnetoresistiv...

Atopic dermatitis (AD, also known as atopic eczema) is driven by a complex relationship between genetic predisposition and environmental exposures. We sought to determine the impact of specific climatic factors on the prevalence of AD in the United states. We used a merged analysis of the 2007 National Survey of Children's Health (NSCH) from a representative sample of 91,642 children aged 0-17 ...
