A comparison of theory and experiment for aeroelastic stability of a hingeless rotor model in hover

Theoretical predictions of aeroelastic stability are compared with experimental, isolated, hingeless-rotor data. The six cases selected represent a torsionally soft rotor having either a stiff or soft pitch-control system in combination with zero precone and droop, 5 degree precone, or -5 degree droop. Analyses from Bell Helicopter Textron, Boeing Vertol, Hughes Helicopters, Sikorsky Aircraft, the National Aeronautics and Space Administration, and the U.S. Army Aeromechanics Laboratory were compared with the experimental data. The correlation ranged from poor to fair

SENSE-project: : environmental assessment for the fruit juice industry (III)

The SENSE research project proposes a set of Key Environmental Performance Indicators (KEPI) to measure the environmental impact of the fruit juice production. The Blueprint Roadmap summarizes the policy context for the SENSE-tool and identifies opportunities and synergies between SENSE and other initiatives.Non peer reviewe

Thermodynamics of Coarse Grained Models of Super-Cooled Liquids

In recent papers, we have argued that kinetically constrained coarse grained models can be applied to understand dynamic properties of glass forming materials, and we have used this approach in various applications that appear to validate this view. In one such paper [J.P. Garrahan and D. Chandler, Proc. Nat. Acad. Sci. USA 100, 9710 (2003)], among other things we argued that this approach also explains why the heat capacity discontinuity at the glass transition is generally larger for fragile materials than for strong materials. In the preceding article, Biroli, Bouchaud and Tarjus (BB&T) [cond-mat/0412024] have objected to our explanation on this point, arguing that the class of models we apply is inconsistent with both the absolute size and temperature dependence of the experimental specific heat. Their argument, however, neglects parameters associated with the coarse graining. Accounting for these parameters, we show here that our treatment of dynamics is not inconsistent with heat capacity discontinuities.Comment: 5 pages, 2 figures. Revised version to appear in J. Chem.

Characterisation framework of key policy, regulatory and governance dynamics and impacts upon European food value chains: Fairer trading practices, food integrity, and sustainability collaborations. : VALUMICS project “Understanding Food Value Chains and Network Dynamics” funded by EU Horizon 2020 G.A. No 727243. Deliverable D3.3

The report provides a framework that categorises the different European Union (EU) policies, laws and governance actions identified as impacting upon food value chains in the defined areas of: fairer trading practices, food integrity (food safety and authenticity), and sustainability collaborations along food value chains. A four-stage framework is presented and illustrated with examples. The evidence shows that European Union policy activity impacting upon food value chain dynamics is increasing, both in terms of the impacts of policies upon the chains, and, in terms of addressing some of the more contentious outcomes of these dynamics. A number of policy priorities are at play in addressing the outcomes of food value chain dynamics. unevenness of the distribution of profit within food value chains, notably to farmers. Regulation of food safety and aspects of authenticity has been a key focus for two decades to ensure a functioning single market while ensuring consumer health and wellbeing. A food chain length perspective has been attempted, notably through regulations such as the General Food Law, and the rationalisation of the Official Controls on food and feed safety. However, there are still gaps in the effective monitoring and transparency of food safety and of food integrity along value chains, as exemplified by misleading claims and criminal fraud. This has led to renewed policy actions over food fraud, in particular. EU regulations, policies and related governance initiatives provide an important framework for national-level actions for EU member states and for EEA members. The more tightly EU-regulated areas, such as food safety, see fewer extra initiatives, but where there is a more general strategic policy and governance push, such as food waste reduction or food fraud, there is greater independent state-level activity. Likewise, there is much more variation in the application of both national and European (Competition) law to govern unfair trading practices impacting upon food value chains. This report presents the findings of a survey of members from the VALUMICS stakeholder platform, that were policy facing food value chain stakeholders across selected European countries, including both EU and EEA Member States. The survey was conducted to check the significance of the main policies identified in the mapping exercise at EU and national levels and so to incorporate the views of stakeholders in the research. The responses suggest the policy concerns identified in EU and national-level research resonate with food value chain stakeholders in participating nations. The report concludes by exploring in more detail how the themes of fairness and of transparency are being handled in the policy activities presented. Highlighted are the ways that both fairness and transparency can be extended within the existing frameworks of EU policy activity. The findings in this report provide an important context for further and detailed research analysis of the workings and dynamics of European food value chains under the VALUMICS project

Heavy meson chiral perturbation theory in finite volume

We present the first step towards the estimation of finite volume effects in heavy-light meson systems using heavy meson chiral perturbation theory. We demonstrate that these effects can be amplified in both light-quark and heavy-quark mass extrapolations (interpolations) in lattice calculations. As an explicit example, we perform a one-loop calculation for the neutral B meson mixing system and show that finite volume effects, which can be comparable with currently quoted errors, are not negligible in both quenched and partially quenched QCD.Comment: Talk presented at Lattice2004(heavy), Fermilab, June 21st-26th, 2004.
