SUPERB bunch-by-bunch feedback R&D
No full textThe SuperB project has the goal to build in Italy, in the Frascati or Tor Vergata area, an asymmetric e{sup +}/e{sup -} Super Flavor Factory to achieve a peak luminosity > 10**36 cm{sup -2} s{sup -1}. The SuperB design is based on collisions with extremely low vertical emittance beams and high beam currents. A source of emittance growth comes from the bunch by bunch feedback systems producing high power correction signals to damp the beams. To limit any undesirable effect, a large R&D program is in progress, partially funded by the INFN Fifth National Scientific Committee through the SFEED (SuperB Feedback) project approved within the 2010 budget. The SuperB project [1] has the goal to build in Italy, in the Frascati or Tor Vergata area, an asymmetric e{sup +}/e{sup -} Super Flavor Factory to achieve a peak luminosity > 10**36 cm{sup -2} s{sup -1}. In the last and current years, the machine layout has been deeply modified, in particular the main rings are now shorter and an option with high currents has been foreseen. In the fig.1 the new SuperB layout is shown. From bunch-by-bunch feedback point of view, the simultaneous presence in the machine parameters, of very low emittance, of the order of 5-10 pm in the vertical plane, and very high currents, at level of 4 Ampere for the Low Energy Ring, asks for designing very carefully the bunch-by-bunch feedback systems. The parameter list is presented in Fig. 2. The bunch-by-bunch feedback design must take care of the risky and exciting challenges proposed in the SuperB specifications, but it should consider also some other important aspects: flexibility in terms of being able to cope to unexpected beam behaviours [2], [3] legacy of previous version experience [4], [5] and internal powerful diagnostics [6] as in the systems previously used in PEP-II and DAFNE [7]

No full textUso de FMEA na melhoria da durabilidade de um acoplamento mecânico aplicado em motor de partida
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Campus Joinville. Engenharia Automotiva.Diante do cenário competitivo da indústria automotiva no Brasil e no mundo, a confiabilidade dos produtos é um dos fatores determinantes no sucesso dos mesmos. A Zen S.A. Indústria Metalúrgica está inserida neste mercado com amplo portfólio de impulsores de partida, acoplamentos mecânicos, tensionadores e polias, voltados para o mercado de reposição de peças como também para montadoras de veículos. Este trabalho trata de um projeto de melhoria de desempenho em durabilidade de um acoplamento mecânico específico, aplicado em motores de partida para automóveis da linha pesada, como motores MWM, Cummins dentre outros. Este acoplamento teve sua venda temporariamente bloqueada devido reclamações frequentes de clientes, os quais alegavam falha prematura do produto. Será apresentado todo o processo de aplicação de um FMEA voltado para geração de soluções técnicas para o produto e para o sistema de qualidade referente a este, de maneira que os eventuais custos na alteração do projeto sejam justificados por métodos científicos consistentes. O FMEA é o método mais utilizado na indústria automotiva para este fim (AIAG, 2011), uma vez que é voltada para a identificação das causas específicas de falhas, fornecendo base para ação na redução da ocorrência e severidade das mesmas e melhorando os mecanismos de detecção (BERTSCHE, 2008). Com a aplicação deste FMEA foi possível, na prática, alterar alguns parâmetros de projeto dos componentes do acoplamento mecânico, que teve seu desempenho em durabilidade mensurado em teste de bancada

BOR3D: A Use-Case-Oriented Software Framework for 3-D Object Recognition
No full textAbstract-3-D object recognition has become a major research topic. New low-cost sensors hit the market making 3-D vision affordable for anyone. On the software side, promising opensource tools and libraries have prospered recently. The most important one, regarding 3-D data processing, undoubtedly is the Point Cloud Library (PCL). From an integrator's point of view, the main benchmarks applied to such a library are the amount of use cases that can be implemented and the effort that is entailed. We have noticed that the scientific community pays little attention to these needs. We hope to change this situation by proposing a framework that is primarily inspired by the PCL. Clearly separating the roles of its users, it leaves integration to the integrators and algorithms to the specialists. This way we hope to provide a means for development teams to participate in the recent advances even if they do not have a special focus on machine vision

No full textModifications in repair and expression of potentially lethal damage (α-PLD) as measured by delayed plating or treatment with β-araA in plateau-phase Ehrlich ascites tumor cells after exposure to charged particles of various specific energies.
No full textThe ability of Ehrlich ascites tumor cells (EAT cells) to repair potentially lethal damage (α-PLD) as demonstrated by either an increase in survival after delayed plating or a decrease in survival after treatment with β-arabinofuranosyladenine (β-araA) was investigated after exposure to protons, deuterons, 3He, 4He, and heavy ions of various specific energies. A significant amount of repair or fixation was observed after delayed plating or treatment with β-araA, respectively, in cells that were exposed to protons of 6-21 MeV energy, reflecting mainly variations in the survival curve shoulder width. Four-hour treatment with 80 μM/liter β-araA resulted in an exponential survival curve for all proton energies tested. A decrease in particle energy increased killing and caused a reduction in D(q) without a significant change in D(O). The survival curve obtained after exposure of cells to 3.4 MeV protons had only a small shoulder and was only slightly modified by either delayed plating or treatment with β-araA, suggesting a decrease in the induction rate of α-PLD. Similar results were also obtained after exposure to deuterons and 4He ions. The results are interpreted as indicating the importance of the specific particle energy and the δ-electron spectrum in the induction of α-PLD. When the results of delayed plating of cells exposed to protons, deuterons, or helium ions were pooled, an exponential relationship between D(q) and penumbra radius was indicated. After exposure to 40Ar ions of 18 MeV specific energy, a shouldered survival curve was obtained, and β-araA significantly enhanced killing by modifying D(q) as well as D(O), a result that also suggests induction of repairable damage by the δ particles produced and interaction of lesions induced within the core of the ion path with penumbra lesions. Based on these results a model is proposed assuming that α-PLD results from interaction, during the course of repair, of pairs of DNA lesions induced within a distanced (i). The model assumes (a) the existence of a critical separation distance d(ic), with the property that pairs of lesions induced with separation distance shorter than d(ic) (expressed as number of base pairs) will always be expressed as lethal, and (b) the existence of a maximum separation distance d(im), with the property that pairs of lesions induced with separation distance larger than d(im) will not interact. Further, it is assumed that the interaction of lesions induced at a distance d(i) such that d(ic) ≤ d(i) ≤ d(im) depends on the postirradiation conditions employed. It is thought that d(i) decreases if cells are kept under conditions preventing proliferation (DP) and that it increases after treatment with β-araA. In both cases variation in d(i) is attributed to treatment-associated alterations in chromatin structure. The observed reduction in the induction of PLD with decreasing particle energy is interpreted as an increase in the fraction of pairs of lesions induced at distances shorter than d(ic), and a concomitant decrease in the fraction of pairs of lesions induced at distances between d(ic) and d(im). These hypothetical lesions are thought either to be located within the particle's penumbra or to arise from combinations of ionizations induced in the particle's core and its penumbra. Finally, the possibility of distinction between LET-dependent effects in D(O) and particle specific energy-dependent effects in D(q) is explored
