Film coat quality
Michael E.Aulton and Andrew M.Twitchell SUMMARY This chapter discusses the desirable properties of polymer film coats with respect to their end usage. The mechanical properties of films were discussed fully in Chapter 12 and so this chapter concentrates on other aspects of film quality such as gloss and roughness, uniformity of film thickness and defects such as cracking, edge splitting, picking, bridging and foam filling of intagliations, etc.
The employer-employee Relationship: A phenomenological Study of Retention and the Information Technology Worker In University of California data, I find evidence that observable background
characteristicsparticularly those describing the composition of the school, rather than the
individuals own backgroundare strong predictors of both SAT scores and collegiate
performance, and that much of the SATs apparent predictive power derives from its
association with these background characteristics.
Biometrics-Unique and Diverse Applications in Nature, Science, and Technology provides a unique sampling of the diverse ways in which biometrics is integrated into our lives and our technology. From time immemorial, we as humans have been intrigued by, perplexed by, and entertained by observing and analyzing ourselves and the natural world around us.
Today, space technology is used as an excellent instrument for Earth observation applications. Data is collected using satellites and other available platforms for remote sensing. Remote sensing data collection detects a wide range of electromagnetic energy which is emitting, transmitting, or reflecting from the Earth's surface. Appropriate detection systems are needed to implement further data processing. Space technology has been found to be a successful application for studying climate change, as current and past data can be dynamically compared.
In some cases, excellence was also observed when basic research, facilities, systems analysis, flight integration, and testing and evaluation were vertically integrated or when programs had achieved success over a period of 10 to 15 years and continue to do so. Key issues, findings,
Weather radar is a vital instrument for observing the atmosphere to help
provide weather forecasts and issue weather warnings to the public. The current
Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage
to most regions of the United States (NRC, 1995). This network was
designed in the mid 1980s and deployed in the 1990s as part of the National
Weather Service (NWS) modernization (NRC, 1999).

Ever since the advent of automatic computation devices,
efforts have been made to answer the question of how to
properly integrate them and take advantage of their capabilities
in education. Educational multimedia systems
promise to make learning easier, more convenient, and thus
more effective. For example, classroom teaching enriched
by vivid presentations promise to improve the motivation
of the learner. Concepts may be given a perceivable existence
in a video show and the observability of important
details can be stressed.
are of high scientific and technical quality, ONR requires that each of its departments undergo an
annual review (with a detailed focus on about one-third of the reviewed department’s programs). The
Aircraft Technology Program reviewed in this report resides within the Strike Technology Division
(Code 351) of the Naval Expeditionary Warfare Science and Technology Department (Code 35) of
The Institutional Review Board approved this retrospective
study, with a waiver of informed consent from the patients. TB outbreaks
occurred in 15 senior high schools and chest radiographs from 58 students with
identical strains of TB were analyzed by restriction fragment length polymorphism
analysis by two independent observers. Lesions of nodule(s), consolidation, or
cavitation in the upper lung zones were classified as typical TB.
The mission of the Office of Naval Research (ONR) is to maintain a close relationship with the
research and development community to support long-range research, foster discovery, nurture future
generations of researchers, produce new technologies that meet known naval requirements, and provide
innovations in fields relevant to the future Navy and Marine Corps. Accordingly, ONR supports
research activities across a broad range of scientific and engineering disciplines.
The growing evidence that human activities can affect the weather on scales
ranging from local to global has added a new and important dimension to the place of
weather modification in the field of atmospheric sciences. There is a need, more urgent
than ever, to understand the fundamental processes related to intentional and
unintentional changes in the atmosphere. The question of how well current technology,
practice, and theory are equipped to meet these broader goals of weather modification is
central to this report.
.labor, to shore up union power, or to restrict the entry of low-skilled workers into the U.S. As the growth in the college premium slowed in the mid-1990s, education- and training-related policies received less attention, but in light of more recent upturns, they may regain popularity. Studies testing the SBTC theory have produced mixed results. The early case in support of the hypothesis was based primarily on the observation of concurrent trends at the macro leve
The Two Hour Primer was created as a quick introduction to the world of S7-200 and has deliberately been kept short. It is not a substitute for the S7-200 manual. Therefore, please observe the instructions given in the S7-200 manual, especially the safety guidelines.
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as
temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass
their data through the network to a main location or sink where the data can be observed
and analysed. A sink or base station acts likean interface between users and the network.
One can retrieve required information from the network by injecting queries and gathering
results from the sink.
Statistical models are empirical. Although they are derived from observations, the
relationship described must have a basis in our underlying understanding of processes
if we are to have faith in the predictive capabilities of the model (National
Research Council 2000).
Modern electrical drive systems are composed principally of; motors, power electronics
components, transformers, analog/digital controllers and sensors or observers. The
improvements and the enormous advances in the fi eld of power electronic (semiconductor
components), converters technology and soft ware/implementation technology
have enabled advanced and complex control techniques. With these advances and robust
control algorithms improved, considerable research eff ort is devoted for developing
optimal techniques of speed and torque control for induction machines....
The regional effects on agricultural income follow from price and quantity impacts on the
input and output side. The bottom line in terms of agricultural income is crucially determined
by the impacts on revenues from raw milk and meats and related impacts on non fodder items.
While fodder activities are important for a detailed analysis, no significant effect on income
can be observed since revenues and costs tend to cancel each other.
