Itâs the End-of-Line for NDE: A Need for In-Line NDE in Advanced Composites Manufacturing
Nondestructive inspections currently play, and will continue to play, a critical role in the manufacturing of composite materials by identifying parts that pass/fail quality targets at the end of the production line. However, there is an urgent need for a paradigm shift to enable high volume composite manufacturing by supplementing end-of-line NDE tools with in-line NDE technologies to inform process decision making. This new approach has the potential to significantly reduce scrap and increase throughput while reducing part variation. The key to in- line NDE is to harness process dynamics by exploiting measurement signatures for diagnosing changes in the material state including deviations or flaws in the material. This talk will discuss case studies in which process signatures in the manufacture of composites are monitored for the purpose of in-line NDE to inform the process. Case studies will focus on carbon fiber manufacturing whereby NDE is used during the process to identify tow form and flaws including broken filaments
Seasonal Occurrence of the White Shark, Carcharodon carcharias, in Waters off the Florida West Coast, with Notes on its Life History
The white shark, Carcharodon carcharias, is considered rare in the Gulf of Mexico; however, recent longline captures coupled with historical landings information suggest that the species occurs seasonally (winter-spring) within this region. We examined a total of seven adult and juvenile white sharks (185-472 em total length) captured in waters off the west coast of Florida. Commercial longline fisheries were monitored for white sharks during all months (1981-94), but this species was captured only from January to April. All white sharks were captured in continental shelf waters from 37 to 222 km off the west coast of Florida when sea surface temperatures ranged from 18.7° to 21.6°C. Depths at capture locations ranged from 20 to 164 m. Fishing gear typically used in Gulf of Mexico offshore fisheries may not be effective at capturing this species, and the apparent rarity of white sharks in this area may be, in part, a function of gear bias
Mercury Levels in Marine and Estuarine Fishes of Florida 1989â2001. 2nd edition revised
The Florida Fish and Wildlife Conservation Commissionâs Florida Marine Research Institute (FWC-FMRI) has
examined total mercury levels in muscle tissue from a variety of economically and ecologically important species
as part of an ongoing study to better understand mercury contamination in marine fishes.The FWC-FMRI Mercury
Program is one of the most comprehensive programs in the United States for monitoring mercury levels in
marine and estuarine fishes. Because mercury, a toxic metallic element, has been shown to bioaccumulate in fish
tissue, humans consuming fish can potentially consume significant levels of mercury.We examined the concentration
of total mercury in 6,806 fish, representing 108 species from 40 families. Species represented all major trophic
groups, from primary consumers to apex predators.The majority of individuals we examined contained low concentrations
of mercury, but concentrations in individual fish varied greatly within and among species. Species
with very low mean or median mercury concentrations tended to be planktivores, detritivores, species that feed
on invertebrates, or species that feed on invertebrates and small fish prey.Apex predators typically had the highest
mercury concentrations. In most species, mercury concentration increased as fish size increased. Sampling
in Florida waters is continuing, and future research relating mercury levels to fish age, feeding ecology, and the
trophic structure of Floridaâs marine and estuarine ecosystems will help us better understand concentrations of
this element in marine fishes. (64pp.
Landscape versus Swampland for Higher Derivative Gravity
We survey recent studies of Gauss-Bonnet gravity and its dual conformal field
theories, including their relation to the violation of the Kovtun-Starinets-Son
viscosity bound. Via holography, we can also study properties such as
microcausality and unitarity of boundary field theory duals. Such studies in
turn supply constraints on bulk gravitational theories, consigning some of them
to the swampland.Comment: 2 pages, prepared for the Proceedings of the Cargese Summer School

PEACH PRICES IN CALIFORNIA IN THE PRESENCE OF TECHNOLOGICAL CHANGE IN THE AGRICULTURAL PESTICIDE INDUSTRY
The potentially adverse effects of pesticides in wide use are causing concern to grow in the agricultural community. Minimizing the risks to human health and the environment created by agricultural pesticides has become a very important issue. The United States Environmental Protection Agency (EPA) has set a high priority on registering safer pesticides. According to the EPA, more than 1 billion pounds of active pesticide ingredients are used in the United States each year. Americans are exposed to pesticides every day through food consumption, cleaning products, and home and work environments. The agricultural pesticide industry has experienced an influx of changes during the past decade. Two of the primary changes affecting the pesticide industry are the introduction of new technology and EPA regulatory changes. On the regulatory front, the EPA requires manufacturers to register and test pesticides before they appear on the market. By 2006, the EPA will review old pesticides to ensure that they meet new safety requirements. These regulatory initiatives have contributed to the industry drive to develop safer and more "environmentally friendly" products for use in agricultural pest control. Technological changes consist of the introduction of new pesticides that are considered to be safer for both humans and the environment. As new technologies and regulatory initiatives are undertaken to ensure an improvement in both the safety of human health and the environment, one must consider how these changes may affect consumers. Specifically, an analysis should be conducted to determine whether or not the technological and regulatory changes have an effect on consumer prices. The recent developments in the agricultural pesticide industry provide several reasons to believe structural change has been occurring in economic relationships that determine peach prices in California. Therefore, we use a vector autoregressive (VAR) model to forecast peach prices by allowing parameters to vary with time. VAR models differ from standard econometric analyses of structural relationships in that they do not apply the usual exclusion restrictions to specify a priori which variables appear in which equations. Instead, a set of distributed lag equations is used to model each variable as a function of other variables in the structural system (Bessler, 1984). The objective of this paper is to forecast peach prices and evaluate dynamic relationships in the peach industry in the presence of technological and regulatory change. A VAR model that explicitly recognizes structural change will be used to forecast peach prices in California. Changes in dynamic relationships between peach prices and relevant economic variables will be considered.Demand and Price Analysis,
Bells of Saint Mary\u27s
The bells of St. Marry\u27s at sweet eventide,Shall call me beloved, to come to your side,And out in the valley in south of the sea, I know you\u27ll be waiting, yes waiting for me.
RefrainThe Bells of St. Mary\u27s,Ah! hear they are callingThe young loves-- true lovesWho come from the sea,And so my beloved,When red leaves are falling,The Love-bells shall ring out- ring outFor you and me.The Bells of St. Mary\u27s, Ah! hear they are callingThe young loves- the true lovesWho come from the sea,And so, my beloved,When red leaves are falling,The love-bells shall ring out- ring outFor you and me.
At the porch of St. Mary\u27s I\u27ll wait there with youIn your soft wedding dress with its ribbons of blue,in the church of St. Mary\u27s sweet voices shall sing,For you and me dearest the wedding bells ring.(to Refrain
