Autonomic communications seek to improve the ability of network and services cope with unpredicted change, including changes in topology, load, task, physical logical characteristics networks that can be accessed, so forth. Broad-ranging autonomic solutions require designers account for a range end-to-end issues affecting programming models, contextual modeling reasoning, decentralised algorithms, trust acquisition maintenance---issues whose may draw on approaches results from surprisingly...
Context is not simply the state of a predefined environment with fixed set interaction resources. It's part process interacting an ever-changing composed reconfigurable, migratory, distributed, and multiscale
<h3>Importance</h3> Excessive antibiotic use has been associated with altered bacterial colonization and may result in resistance, fungemia, necrotizing enterocolitis (NEC), mortality. Exploring the association between exposure neonatal outcomes other than infection-related morbidities provide insight on importance of rational use, especially setting culture-negative sepsis. <h3>Objective</h3> To evaluate trend among all hospitalized very low-birth-weight (VLBW) infants across Canada rates...
Information on factors that influence parental decisions for actual human papillomavirus (HPV) vaccine receipt in publicly funded, school-based HPV programs girls is limited. We report the level of uptake first dose vaccine, and determine associated with a funded program British Columbia, Canada.All parents enrolled grade 6 during academic year September 2008-June 2009 province Columbia were eligible to participate. Eligible households identified through provincial public health information...
Immunization with a meningococcal tetravalent (serogroup ACWY) glycoconjugate vaccine is recommended for all US adolescents. However, the currently licensed poorly immunogenic in infancy, when highest rates of disease are observed.To determine immunogenicity novel CRM(197)-conjugated (MenACWY) infants.Randomized, open-label, controlled study 225 UK and 196 Canadian 2-month-olds from August 2004 to September 2006.UK infants received primary course MenACWY (at 2, 3, 4 months or 2 months)...
Abstract Pervasive computing is by its nature open and extensible, must integrate the information from a diverse range of sources. This leads to problem exchange, so sub-systems agree on shared representations. Ontologies potentially provide well-founded mechanism for representation exchange such structured information. A number ontologies have been developed specifically use in pervasive computing, none which appears cover adequately space concerns applicable application designers. We...
Sensing of the application environment is main purpose a wireless sensor network. Most existing energy management strategies and compression techniques assume that sensing operation consumes significantly less than radio transmission reception. This assumption does not hold in number practical applications. consumption these applications may be comparable to, or even greater than, radio. In this work, we support claim by quantitative analysis operational costs popular sensors, radios motes....
Wireless sensor networks (WSNs) are highly resource constrained in terms of power supply, memory capacity, communication bandwidth, and processor performance. Compression sampling, data, communications can significantly improve the efficiency utilization three these resources, namely, bandwidth. Recently, there have been a large number proposals describing compression algorithms for WSNs. These diverse involve different approaches. It is high time that individual efforts put into perspective...
Immunization of pregnant women with tetanus-diphtheria-acellular pertussis vaccine (Tdap) provides protection against to the newborn infant.In a randomized, controlled, observer-blind, multicenter clinical trial, we measured safety and immunogenicity Tdap during pregnancy effect on infant's immune response primary vaccination at 2, 4, 6 months booster 12 age. A total 273 received either or tetanus-diphtheria (Td) in third trimester provided information for analysis samples analyses; 261...
Efforts since 2001 to design self-managing systems have yielded many impressive achievements, yet the original vision of autonomic computing remains unfulfilled. Researchers must develop a comprehensive engineering approach create effective solutions for next-generation enterprise and sensor systems.
This paper presents a novel reference-free ultrasonic indoor location system. Unlike most previous proposals, the mobile device (MD) determines its own position based only on signals received at compact sensor array and sent by fixed independent beacon. No radio frequency or wired timing reference signal is used. Furthermore, system privacy aware one way in that receive-only MD from transmit-only beacons. The uses hybrid angle of arrival (AoA)-time flight (ToF) with lock algorithm to...
Social networks represent a sophisticated tool for accessing the preferences and properties of individuals groups. Thus, they potentially allow up-to-date, richly annotated contextual data to be acquired as side effect users' everyday use services. In this paper, we explore how such "social sensing" could integrated into pervasive systems. We frame survey possible approaches an integration, discuss open issues challenges facing researchers.
This paper presents a novel method for ultrasonic range estimation. The uses wideband frequency-hop spread spectrum signal to increase robustness noise and reverberation. applies cross-correlation with earliest peak search minimum variance technique correct the error in time-of-flight estimate within one wavelength of carrier before applying phase-shift subwavelength refinement. can be implemented digitally software only requires low-cost hardware transmission acquisition. Experimental...
Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems coupling and we report in this paper an empirical analysis between street network subway for two metropolitan areas London New York. We observe a similar behaviour quantities related quickest paths suggesting existence generic mechanisms operating beyond local peculiarities specific...
