    CERN's clubs are planning to celebrate the Organization's 50th anniversary by organising a variety of special events. It's raining projects! CERN's clubs have chosen to celebrate the Organization's Golden Jubilee, each in its own style, by organising a whole host of anniversary events. While the Cine-Club continues to screen films made in the Member States on Thursday evenings, other clubs are organising special races and tournaments to honour CERN's 50th year. The CERN Rugby Club led the way in early April when it hosted a children's tournament which brought the Laboratory firmly into the view of its many young participants. On 24 April, the Cycling Club moves to centre stage as it takes its members on a unique 50-km discovery trip around the countryside above the tunnel of the future LHC. The Croquet Club, the Running Club, the Horse Riding Club and the Golf Club will all be joining the party in May and June. After that, football, softball, cycling, pétanque and sailing are just some of the items on a sp...

    Full Text Available The joined wing concept is an unconventional airplane configuration, known since the mid-twenties of the last century. It has several possible advantages, like reduction of the induced drag and weight due to the closed wing concept. The inverted joined wing variant is its rarely considered version, with the front wing being situated above the aft wing. The following paper presents a performance prediction of the recently optimized configuration of this airplane. Flight characteristics obtained numerically were compared with the performance of two classical configuration airplanes of similar category. Their computational fluid dynamics (CFD models were created basing on available documentation, photographs and some inverse engineering methods. The analysis included simulations performed for a scale of 3-meter wingspan inverted joined wing demonstrator and also for real-scale manned airplanes. Therefore, the results of CFD calculations allowed us to assess the competitiveness of the presented concept, as compared to the most technologically advanced airplanes designed and manufactured to date. At the end of the paper, the areas where the inverted joined wing is better than conventional airplane were predicted and new research possibilities were described.

    1972-01-01

    Requirements for advanced aircraft have led to more extensive use of titanium alloys and the resultant search for joining processes which can produce lightweight, high strength airframe structures efficiently. As a result, electron beam welding has been investigated. The following F-14A components are now being EB welded in production and are mainly annealed Ti-6Al-4V except for the upper wing cover which is annealed Ti-6Al-6V-2Sn: F-14A wing center section box, and F-14A lower and upper wing covers joined to wing pivot fitting assemblies. Criteria for selection of welding processes, the EB welding facility, development work on EB welding titanium alloys, and F-14A production and sliding seal electron beam welding are reported.

The author presents a brief history of the phenomenon; Flemish separatism is seen in the context of the European integration and in comparison with other separatist movements. Having been articulated politically in 1990s, Flemish separatism is now an inherent part of the right-wing populist party programs: of the Flemish Bloc program (since 2004 it is Flemish Interest as an independence appeal, and of the New Flemish Alliance program as a call for further state reforming, aiming at the creation of a confederative system. A number of Flanders independence plans have been elaborated, whose authors posit that it is not Flanders that should quit the federation, but Belgium should officially disintegrate into two parts (because only in this case the French-speaking part of the country will not become the sole heir of the federation. The separatists usually see the EU as an institutional barrier; however, its role is acknowledged in the strengthening of regions’ position in the entireEurope. The elements that should keep the Belgian federation intact are not de facto functioning properly; however, gaining full independence would only fix the de jure already existing administrative and political split, and would also create a number of administrative problems. That is why the percentage of the Flemish independence proponents has declined recently, and the Belgian federation is now in a certain “break-even point” that can be distorted by the right-wing populist parties.

    Full Text Available Latest developments of the global economic crisis but also the way people use to build their perception on their own identity brought interesting developments in the political sphere. Thus, Belgian right wings parties have amplified the identity discourse. Belgian political crisis is an interesting example in terms of political reconciliation. The problem became so acute that makes discussion on Belgian state dissolution/dividing to be almost trivial. Interrogation on problems like: should regionalization be a priority? Which will be the future of federal state concepts? It is the question about social solidarity or about autonomy and regional development? What kind of news can occur in institutional organization? The problem is not really the way the two communities (Flemish and Walloons can live together separately in a federation, each speaking its own language, building a separate culture, having own perception of things. The most difficult to manage is the problem of economic redistribution. This and no other disagreements made the issue of the Belgian state segregation to be worthy of discussion. Centrifugal dynamics that happen in Europe lately are signs of rethinking their identity. The idea of confederalism in the case study on Belgium appears to be a possible solution to the crisis problem and generate a new and radical reform of the state.

  16. The South Has Risen Again: Thoughts on the Tea Party and the Recent Rise of Right-Wing Racism.

    2016-01-01

    This paper examines the significance of racism in fueling the recent rise of the Tea Party and related Right-Wing political groups and activity. It briefly explores some of the history of racism in this country that has been directed toward African Americans and how it has influenced political developments from Colonial times to the present. It suggests that this racist resurgence can be seen, in part, as a re-enactment of the trauma of the Civil War by the descendants, and those who identify with them, who were on the losing side of that conflict.

  19. “I joined the Party to keep ourselves out of the System.” Neo-Pagan Survival Strategies in Socialist Hungary

    Directory of Open Access Journals (Sweden)

    Csáji László Koppány

    2017-01-01

    Full Text Available The paper presents a Hungarian Ethno-Pagan group (Bolyanest which was established in 1979, active in and around Budapest. In the early 80s the group was a forum for New Age-like ideas: Gaia cult, esoteric concepts, natural-based peace-campaigns, yoga, Reiki and other theories about nature, love, humanity, human potentials and peace. The author analyses how this group shifted slowly from the New Age to the Neo-Pagan characteristics during the 80s. The group had a complex survival strategy, which contained several conscious and instinctual responses to the communist system. One of these was the use of espionage: having an informer within the police from among their membership to provide reports that were to benefit the movement. Another strategy was that some members joined the Socialist Party to reassure the communist authorities of their loyalty. The Hungarian society considered communism as a field of parallel realities: one was the communist system‘s narratives, and the other was the society‘s private discourses. Beside these, Bolyanest members created a third reality: the group‘s own value-system and narratives. The cognitive ability to alternate between the realities was also an important key to survival.

  20. The issue of Romania’s joining the First World War in the vision of the leaders of the political parties – the National Liberal Party and the Conservative Party

    2017-12-01

    Full Text Available Romania's entry into the First World War was preceded by fierce diplomatic battles between the two warring parties – the Entente and the Triple Alliance – regarding its involvement in the conflict on one side or the other. No less dramatic was the internal struggle waged by representatives of civil society - writers, doctors, engineers, historians, leaders of political parties, both ruling and opposition. They were brought up in the spirit of nationalism and spiritual and moral values, formed on the basis of the national liberation struggle of the 19th century. Each of them motivated entry into the war, defending his own interests, trying to get as much political dividends as possible, sometimes taking unfavorable decisions, ignoring the real economic and military potential of the Romanian state. What seemed simple at first glance turned out to be in fact an equation with many unknowns. Today we know the result - the disappearance from the political map of several empires and the emergence of other political systems and regimes, more severe, which will determine the fate and history of many peoples, including Romanian.

  1. The dynamics of radical right-wing populist party preferences and perceived group threat: A comparative panel analysis of three competing hypotheses in the Netherlands and Germany.

    Berning, Carl C; Schlueter, Elmar

    2016-01-01

    Existing cross-sectional research considers citizens' preferences for radical right-wing populist (RRP) parties to be centrally driven by their perception that immigrants threaten the well-being of the national ingroup. However, longitudinal evidence for this relationship is largely missing. To remedy this gap in the literature, we developed three competing hypotheses to investigate: (a) whether perceived group threat is temporally prior to RRP party preferences, (b) whether RRP party preferences are temporally prior to perceived group threat, or (c) whether the relation between perceived group threat and RRP party preferences is bidirectional. Based on multiwave panel data from the Netherlands for the years 2008-2013 and from Germany spanning the period 1994-2002, we examined the merits of these hypotheses using autoregressive cross-lagged structural equation models. The results show that perceptions of threatened group interests precipitate rather than follow citizens' preferences for RRP parties. These findings help to clarify our knowledge of the dynamic structure underlying RRP party preferences. Copyright © 2015 Elsevier Inc. All rights reserved.

  2. Aeroservoelastic Wind-Tunnel Tests of a Free-Flying, Joined-Wing SensorCraft Model for Gust Load Alleviation

    2011-01-01

    A team comprised of the Air Force Research Laboratory (AFRL), Boeing, and the NASA Langley Research Center conducted three aeroservoelastic wind-tunnel tests in the Transonic Dynamics Tunnel to demonstrate active control technologies relevant to large, exible vehicles. In the first of these three tests, a full-span, aeroelastically scaled, wind-tunnel model of a joined-wing SensorCraft vehicle was mounted to a force balance to acquire a basic aerodynamic data set. In the second and third tests, the same wind-tunnel model was mated to a new, two-degree-of-freedom, beam mount. This mount allowed the full-span model to translate vertically and pitch. Trimmed flight at -10% static margin and gust load alleviation were successfully demonstrated. The rigid body degrees of freedom required that the model be own in the wind tunnel using an active control system. This risky mode of testing necessitated that a model arrestment system be integrated into the new mount. The safe and successful completion of these free-flying tests required the development and integration of custom hardware and software. This paper describes the many systems, software, and procedures that were developed as part of this effort. The balance and free ying wind-tunnel tests will be summarized. The design of the trim and gust load alleviation control laws along with the associated results will also be discussed.

  4. Radical Right-Wing Parties in Former Communist Countries: Challenges to Liberal Democracy or a Socio-Economic Protest?

    Directory of Open Access Journals (Sweden)

    Vedran Obućina

    2011-01-01

    Full Text Available Economic and social crises provide an opportunity for protest parties to raise their voices and to win new positions in the political arena. Many analysts deem that the parties of the radical Right gained momentum exactly with the protests by citizens against globalisation, economic deprivation and the impact of the economic crisis. A more detailed study of the radicalisation of politics reveals that the simplification of this thesis does not have a particularly strong justification. In the absence of clear methodologies, political scientists and other social scientists seek to formulate theories based on empirical research. One of the frequent theoretical frameworks is the attitude of populist parties toward the socio-economic situation in the country. According to this thesis, in the period of a global crisis, the percentage of voters of radical political options increases, mostly out of protest, and not as an anti-systemic phenomenon. This paper also examines the situation in Central Europe, as well as the outcomes of this year's elections in Hungary, Latvia and Slovakia as countries with a strong radical Right. By analysing the cases of these countries, the author seeks to establish whether the socio-economic theory can be applied, or whether these countries are facing greater challenges to liberal democracy posed by the far-right pole.

    Full Text Available We focus on a form of joining conversations among multiple parties in service-oriented applications where a client may asynchronously join an existing conversation without need to know in advance any information about it. More specifically, we show how the correlation mechanism provided by orchestration languages enables a form of conversation joining that is completely transparent to clients and that we call 'blind-date joining'. We provide an implementation of this strategy by using the standard orchestration language WS-BPEL. We then present its formal semantics by resorting to COWS, a process calculus specifically designed for modelling service-oriented applications. We illustrate our approach by means of a simple, but realistic, case study from the online games domain.

    A workshop to obtain input from industry on the establishment of the Precision Joining Center (PJC) was held on July 10--12, 1991. The PJC is a center for training Joining Technologists in advanced joining techniques and concepts in order to promote the competitiveness of US industry. The center will be established as part of the DOE Defense Programs Technology Commercialization Initiative, and operated by EG G Rocky Flats in cooperation with the American Welding Society and the Colorado School of Mines Center for Welding and Joining Research. The overall objectives of the workshop were to validate the need for a Joining Technologists to fill the gap between the welding operator and the welding engineer, and to assure that the PJC will train individuals to satisfy that need. The consensus of the workshop participants was that the Joining Technologist is a necessary position in industry, and is currently used, with some variation, by many companies. It was agreed that the PJC core curriculum, as presented, would produce a Joining Technologist of value to industries that use precision joining techniques. The advantage of the PJC would be to train the Joining Technologist much more quickly and more completely. The proposed emphasis of the PJC curriculum on equipment intensive and hands-on training was judged to be essential.

    2012-10-16

    A method of joining dissimilar materials having different ductility, involves two principal steps: Decoration of the more ductile material's surface with particles of a less ductile material to produce a composite; and, sinter-bonding the composite produced to a joining member of a less ductile material. The joining method is suitable for joining dissimilar materials that are chemically inert towards each other (e.g., metal and ceramic), while resulting in a strong bond with a sharp interface between the two materials. The joining materials may differ greatly in form or particle size. The method is applicable to various types of materials including ceramic, metal, glass, glass-ceramic, polymer, cermet, semiconductor, etc., and the materials can be in various geometrical forms, such as powders, fibers, or bulk bodies (foil, wire, plate, etc.). Composites and devices with a decorated/sintered interface are also provided.

    Full Text Available In the contemporary family law, parents are obliged to arrange the joined implementation of the parenting rights either by their own will or through the help of their lawyers and/or mediators. This institute of mutual agreement is known as joined custody or joined implementation of the parenting right after the divorce of the marriage. This institute makes it possible for parents who live separately to arrange their custody rights in the most convenient way for the child. With a joined custody agreement, the parents accept the obligation to implement all the rights and duties that constitute the parenting right even in case of their separation. Through not dividing their rights from their obligations and with the aim of being closer to the needs of the child, the institute of joined custody helps avoid the feelings of hostility and disagreement in regard to the judicial decision which gives permanent custody to one of the parents. This institute is incorporated in the family law of many countries (Sweden, Norway, Finland, Denmark, UK, France, Italy, Germany, Belgium, Switzerland, Hungary, Czech Republic, USA and Australia. This article aims to emphasize the need to introduce in the family law of RM an explicit provision for joined and responsible custody after the divorce in order to achieve the best interest of the child. There is a joined initiative of parents who live separately from their children who request the amendment of the Family Law of RM in this direction.

    A pulsed joining tool includes a tool body that defines a cavity that receives an inner tubular member and an outer tubular member and a pulse joining cartridge. The tubular members are nested together with the cartridge being disposed around the outer tubular member. The cartridge includes a conductor, such as a wire or foil, that extends around the outer tubular member and is insulated to separate a supply segment from a return segment. A source of stored electrical energy is discharged through the conductor to join the tubular members with an electromagnetic force pulse.

    1998-09-01

    Both fundamental and practical aspects of ceramic joining are understood well enough for many, if not most, applications requiring moderate strengths at room temperature. This paper argues that the two greatest needs in ceramic joining are for techniques to join buried interfaces by selective heating, and methods for joining ceramics for use at temperatures of 800 to 1,200 C. Heating with microwave radiation or with high-energy electron beams has been used to join buried ceramic interfaces, for example SiC to SiC. Joints with varying levels of strength at temperatures of 600 to 1,000 C have been made using four techniques: (1) transient liquid phase bonding; (2) joining with refractory braze alloys; (3) joining with refractory glass compositions; and (4) joining using preceramic polymers. Joint strengths as high as 550 MPa at 1,000 C have been reported for silicon nitride-silicon nitride bonds tested in four-point flexure.

  7. Fast and scalable inequality joins

    KAUST Repository

    Khayyat, Zuhair

    2016-09-07

    Inequality joins, which is to join relations with inequality conditions, are used in various applications. Optimizing joins has been the subject of intensive research ranging from efficient join algorithms such as sort-merge join, to the use of efficient indices such as (Formula presented.)-tree, (Formula presented.)-tree and Bitmap. However, inequality joins have received little attention and queries containing such joins are notably very slow. In this paper, we introduce fast inequality join algorithms based on sorted arrays and space-efficient bit-arrays. We further introduce a simple method to estimate the selectivity of inequality joins which is then used to optimize multiple predicate queries and multi-way joins. Moreover, we study an incremental inequality join algorithm to handle scenarios where data keeps changing. We have implemented a centralized version of these algorithms on top of PostgreSQL, a distributed version on top of Spark SQL, and an existing data cleaning system, Nadeef. By comparing our algorithms against well-known optimization techniques for inequality joins, we show our solution is more scalable and several orders of magnitude faster. © 2016 Springer-Verlag Berlin Heidelberg

  20. Low Reynolds Number Wing Transients in Rotation and Translation

    Jones, Anya; Schlueter, Kristy

    2012-11-01

    The unsteady aerodynamic forces and flow fields generated by a wing undergoing transient motions in both rotation and translation were investigated. An aspect ratio 2 flat plate wing at a 45 deg angle of attack was driven over 84 deg of rotation (3 chord-lengths of travel at 3/4 span) and 3 and 10 chord-lengths of translation in quiescent water at Reynolds numbers between 2,500 and 15,000. Flow visualization on the rotating wing revealed a leading edge vortex that lifted off of the wing surface, but remained in the vicinity of the wing for the duration of the wing stroke. A second spanwise vortex with strong axial flow was also observed. As the tip vortex grew, the leading edge vortex joined the tip vortex in a loop-like structure over the aft half of the wing. Near the leading edge, spanwise flow in the second vortex became entrained in the tip vortex near the corner of the wing. Unsteady force measurements revealed that lift coefficient increased through the constant-velocity portion of the wing stroke. Forces were compared for variations in wing acceleration and Reynolds number for both rotational and translational motions. The effect of tank blockage was investigated by repeating the experiments on multiple wings, varying the distance between the wing tip and tank wall.

    Hot Isostatic Pressing (HIP) is investigated as a technique for joining the cermet WC-15% Co to itself. Encapsulation of the specimens prior to HIPing was carried out using steel encapsulation, glass encapsulation and self encapsulation. The bonds were evaluated using a four point bend method. It is shown that the glass and steel encapsulation methods have a number of inherent problems which make them inappropriate for near net shape processing. In contrast the novel self encapsulation method, described for the first time in this communication, is both simple and effective, producing joined material with bulk strength. The concept of self encapsulation is potentially widely applicable for joining composite materials.

Those questions cover: the ideology of green political parties, their number and influence, both in general and in Serbia. The first part of work is generally speaking about political parties - their definition, ideology, role and action. Main thesis in this work is that green political parties, by their appearance, were something new on the political scene. But quickly, because of objective and subjective reasons, they were changing original ideas and were beginning to resemble to all other political parties. In this way, they lost their vanguard and political alternativeness.

  8. Parties heed (with caution)

    Fisher, Justin

    2011-01-01

    Despite comprehensive reform (Political Parties, Elections and Referendums Act) and recent review (Phillips Review in 2007) of party finance in Britain, public opinion of party finance remains plagued by perceptions of corruption, undue influence from wealthy donors, carefree and wasteful spending and, more generally, from the perception that there is just ‘too much money’ in politics. In this article we argue that knowledge of and attitudes to party finance matter, not least because advocates of reform have cited public opinion as evidence for reform. However, because attitudes to party finance are part of a broader attitudinal structure, opinion-led reforms are unlikely to succeed in increasing public confidence. Using data generated from YouGov’s online panel (N=2,008), we demonstrate that the public know little of the key provisions regulating party finance and attitudes to party finance can be explained along two underlying dimensions – Anti-Party Finance and Reformers. As such, we consider whether parties and politicians should be freed from the constraints of public opinion in reforming party finance. PMID:29097904

From this departure we seek out an alternative variable by posing...... the question: Do party brands influence voting behavior? Currently, we do not know because the two research fields of voting behavior and party brands are currently not explicitly linked.

In this light, the article first distinguishes the brand concept from related...

    Kelloway, E Kevin; Francis, Lori; Catano, Victor M; Dupré, Kathryne E

    2008-07-01

    Labor strikes are often seen as battles for public support. Members of the public are asked to show respect for a strike by refusing to cross the picket line or by joining strikers on the picket line. Such public support may affect the morale of strikers and influence the strike's duration. Despite the perceived importance of the public in labor disputes, members of third parties have not been considered in previous strike research. In 2 studies, the authors show that a new measure of third-party strike support is unidimensional and highly reliable. In both cases, union attitudes and perceptions of distributive justice were significant predictors of support for strike action. Those who are more supportive of unions in general and believe that the contract offered to the strikers was unfair were more likely to support the strike by engaging in such actions as conversing with strikers, writing letters, and refusing to cross the picket line.

  17. Chrysler Upset Protrusion Joining Techniques for Joining Dissimilar Metals

    Energy Technology Data Exchange (ETDEWEB)

    Logan, Stephen [FCA US LLC, Auburn Hills, MI (United States)

    2017-09-28

    The project goal was to develop and demonstrate a robust, cost effective, and versatile joining technique, known as Upset Protrusion Joining (UPJ), for joining challenging dissimilar metal com-binations, especially those where one of the metals is a die cast magnesium (Mg) component. Since two of the key obstacles preventing more widespread use of light metals (especially in high volume automotive applications) are 1) a lack of robust joining techniques and 2) susceptibility to galvanic corrosion, and since the majority of the joint combinations evaluated in this project include die cast Mg (the lightest structural metal) as one of the two materials being joined, and since die casting is the most common and cost effective process for producing Mg components, then successful project completion provides a key enabler to high volume application of lightweight materials, thus potentially leading to reduced costs, and encouraging implementation of lightweight multi-material vehicles for significant reductions in energy consumption and reduced greenhouse gas emissions. Eco-nomic benefits to end-use consumers are achieved primarily via the reduction in fuel consumption. Unlike currently available commercial processes, the UPJ process relies on a very robust mechanical joint rather than intermetallic bonding, so the more cathodic material can be coated prior to joining, thus creating a robust isolation against galvanic attack on the more anodic material. Additionally, since the UPJ protrusion is going through a hole that can be pre-drilled or pre-punched prior to coating, the UPJ process is less likely to damage the coating when the joint is being made. Further-more, since there is no additional cathodic material (such as a steel fastener) used to create the joint, there is no joining induced galvanic activity beyond that of the two parent materials. In accordance with its originally proposed plan, this project has successfully developed process variants of UPJ to enable

  3. Lightning fast and space efficient inequality joins

    KAUST Repository

    Khayyat, Zuhair

    2015-09-01

    Inequality joins, which join relational tables on inequality conditions, are used in various applications.

    Full Text Available The first modern political parties were formed at the end of the 18th century and have, from those times up to now, undergone 4 developing phases; each of the phases is bound to ideal-type political party model: cadre parties, mass parties, catch-all parties and cartel parties. Each of these party models differentiates in various characteristics: party foundation, number of members, and way of leading the election campaigns, but also in ways of financing. This paper describes the above mentioned 4 phases of political parties’ development and 4 phases of parties' finances development; it will be analysed in detail positive and negative sides of each of the models of party financing.

    Reported herein is the final report on a U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) project with industry cost-share that was jointly carried out by Oak Ridge National Laboratory (ORNL), ExxonMobil Upstream Research Company (ExxonMobil), and MegaStir Technologies (MegaStir). The project was aimed to advance the state of the art of friction stir welding (FSW) technology, a highly energy-efficient solid-state joining process, for field deployable, on-site fabrications of large, complex and thick-sectioned structures of high-performance and high-temperature materials. The technology innovations developed herein attempted to address two fundamental shortcomings of FSW: 1) the inability for on-site welding and 2) the inability to weld thick section steels, both of which have impeded widespread use of FSW in manufacturing. Through this work, major advance has been made toward transforming FSW technology from a “specialty” process to a mainstream materials joining technology to realize its pervasive energy, environmental, and economic benefits across industry.

    Science.gov (United States)

    van de Wardt, Marc; Berkhout, Joost; Vermeulen, Floris

    2017-06-01

    This study introduces a population-ecological approach to the entry and exit of political parties. A primary proposition of population ecology is that organizational entry and exit depends on the number of organizations already present: that is, density. We propose that political parties mainly experience competition from parties in the same ideological niche (left, centre, right). Pooled time-series analyses of 410 parties, 263 elections and 18 West-European countries largely support our expectations. We find that political parties are more likely to exit when density within their niche increases. Also there is competition between adjacent ideological niches, i.e. between centrist and right-wing niches. In contrast to our expectations, neither density nor institutional rules impact party entry. This raises important questions about the rationale of prospective entrants.

  20. Inflatable Wing Deployment Sequence

    2001-01-01

    The deployable, inflatable wing technology demonstrator aircraft's wings begin deploying following separation from its carrier aircraft during a flight experiment conducted by the NASA Dryden Flight Research Center, Edwards, California. Wing deployment time is typically on the order of a third of a second, almost faster than the human eye can see. Three successful flights of the I2000 inflatable wing aircraft occurred. During the flights, the team air-launched the radio-controlled (R/C) I2000 from an R/C utility airplane at an altitude of 800-1000 feet. As the I2000 separated from the carrier aircraft, its inflatable wings 'popped-out,' deploying rapidly via an on-board nitrogen bottle. The aircraft remained stable as it transitioned from wingless to winged flight. The unpowered I2000 glided down to a smooth landing under complete control.

    The Labour leadership contest of 2015 resulted in the election of the veteran Left-wing backbencher, Jeremy Corbyn, who clearly defeated the early favourite, Andy Burnham. Yet Corbyn enjoyed very little support among Labour MPs, and his victory plunged the PLP into turmoil, particularly as he was widely viewed as incapable of leading the Party to victory in the 2020 general election. Given that, much of the established academic literature on Party leadership contests emphasises the ability to...

  4. From left to right: processing acronyms referring to names of political parties activates spatial associations.

    Science.gov (United States)

    van Elk, Michiel; van Schie, Hein T; Bekkering, Harold

    2010-11-01

    In line with previous studies, showing that abstract concepts like "power" or "god" implicitly activate spatial associations, in the present study we hypothesized that spatial associations are coactivated during the processing of acronyms referring to names of political parties as well. In four studies, it was found that the reading of these acronyms was accompanied by the implicit activation of spatial left-right associations. That is, participants responded faster to left-wing parties by means of a left-hand button press and vice versa for right-wing parties (Experiments 1 to 3), and participants responded faster when a political acronym was presented at the side of the screen corresponding to the political orientation of the acronym (Experiment 4). Interestingly, a correlation was observed between the effect size for left-wing parties and participants' political preferences, suggesting that the reaction time effects reflect the perceived distance of a party to one's own political orientation. Together these findings indicate that spatial representations activated in response to political acronyms do not simply reflect lexical-semantic associations or spatial metaphors, but representations of parties' political orientation relative to one's own sociopolitical position.

  6. Efficient Joins with Compressed Bitmap Indexes

    Energy Technology Data Exchange (ETDEWEB)

    Computational Research Division; Madduri, Kamesh; Wu, Kesheng

    2009-08-19

    We present a new class of adaptive algorithms that use compressed bitmap indexes to speed up evaluation of the range join query in relational databases. We determine the best strategy to process a join query based on a fast sub-linear time computation of the join selectivity (the ratio of the number of tuples in the result to the total number of possible tuples). In addition, we use compressed bitmaps to represent the join output compactly: the space requirement for storing the tuples representing the join of two relations is asymptotically bounded by min(h; n . cb), where h is the number of tuple pairs in the result relation, n is the number of tuples in the smaller of the two relations, and cb is the cardinality of the larger column being joined. We present a theoretical analysis of our algorithms, as well as experimental results on large-scale synthetic and real data sets. Our implementations are efficient, and consistently outperform well-known approaches for a range of join selectivity factors. For instance, our count-only algorithm is up to three orders of magnitude faster than the sort-merge approach, and our best bitmap index-based algorithm is 1.2x-80x faster than the sort-merge algorithm, for various query instances. We achieve these speedups by exploiting several inherent performance advantages of compressed bitmap indexes for join processing: an implicit partitioning of the attributes, space-efficiency, and tolerance of high-cardinality relations.

  8. Authenticated join processing in outsourced databases

    KAUST Repository

    Yang, Yin

    2009-01-01

    Database outsourcing requires that a query server constructs a proof of result correctness, which can be verified by the client using the data owner\\'s signature. Previous authentication techniques deal with range queries on a single relation using an authenticated data structure (ADS). On the other hand, authenticated join processing is inherently more complex than ranges since only the base relations (but not their combination) are signed by the owner. In this paper, we present three novel join algorithms depending on the ADS availability: (i) Authenticated Indexed Sort Merge Join (AISM), which utilizes a single ADS on the join attribute, (ii) Authenticated Index Merge Join (AIM) that requires an ADS (on the join attribute) for both relations, and (iii) Authenticated Sort Merge Join (ASM), which does not rely on any ADS. We experimentally demonstrate that the proposed methods outperform two benchmark algorithms, often by several orders of magnitude, on all performance metrics, and effectively shift the workload to the outsourcing service. Finally, we extend our techniques to complex queries that combine multi-way joins with selections and projections. ©2009 ACM.

The current focus is on identification of the most effective joining methods for scale-up to large tube assemblies, including joining using SiC produced in situ from chemical precursors. During FY 1996, a new microwave applicator was designed, fabricated and tested that provides the capability for vacuum baking of the specimens and insulation and for processing under inert environment. This applicator was used to join continuous fiber-reinforced (CFCC) SiC/SiC composites using a polymer precursor to form a SiC interlayer in situ.

  17. The Finns Party: Euroscepticism, Euro Crisis, Populism and the Media

    Directory of Open Access Journals (Sweden)

    Juha Herkman

    2017-03-01

    Full Text Available In many European countries, populist right-wing parties have been most noticeable representatives of Euroscepticism. In Finland, the Finns Party (Perussuomalaiset has been a constant promoter of organisational Euroscepticism through its leader, Timo Soini. The party broke through in Finland’s ‘big bang elections’ of 2011, when the most debated issue was the European economic crisis, which was dominated by Eurosceptic Soini. Research concerning the relationship between the media, populism and Euroscepticism usually focus on national or European Parliament elections. This study analyses the media portrayal of the Eurosceptic Finns Party during times other than elections, focusing on the Finland’s overall Euro crisis press coverage in 2010–2012. The analysis shows that the populist Finns Party has been a minor player in that coverage, which was dominated by the Euro positive political and economic elites. Differences between newspapers indicate that journalistic routines and political context direct media coverage toward particular framings, even when the media proclaims itself politically independent and neutral.

    Ericsson, L. E.; Reding, J. P.

    1976-01-01

    On present day high performance aircraft, a large portion of the lift is generated by leading edge vortices generated by flow separation off the highly swept leading edges of the lifting surfaces employed. It has been shown in an earlier paper how the vortex effects can be superimposed on a modified slender wing theory to give the unsteady longitudinal characteristics of sharp-edged delta wings up to very high angles of attack. The present paper extends the previous analysis to include the effects of leading edge roundness and trailing edge sweep on the aerodynamic characteristics. The paper also derives analytic means for prediction of the yaw stability of slender wings and the first order effects of Mach number. Universal scaling laws are defined for rapid preliminary design estimates of the slender wing lift and rolling moment. The results indicate that simple analytic tools can be developed to predict the aeroelastic characteristics of the space shuttle ascent configuration with its complicated flow field and aeroelastic cross-couplings.

  3. Trajectory similarity join in spatial networks

    KAUST Repository

    Shang, Shuo

    2017-09-07

    The matching of similar pairs of objects, called similarity join, is fundamental functionality in data management. We consider the case of trajectory similarity join (TS-Join), where the objects are trajectories of vehicles moving in road networks. Thus, given two sets of trajectories and a threshold θ, the TS-Join returns all pairs of trajectories from the two sets with similarity above θ. This join targets applications such as trajectory near-duplicate detection, data cleaning, ridesharing recommendation, and traffic congestion prediction. With these applications in mind, we provide a purposeful definition of similarity. To enable efficient TS-Join processing on large sets of trajectories, we develop search space pruning techniques and take into account the parallel processing capabilities of modern processors. Specifically, we present a two-phase divide-and-conquer algorithm. For each trajectory, the algorithm first finds similar trajectories. Then it merges the results to achieve a final result. The algorithm exploits an upper bound on the spatiotemporal similarity and a heuristic scheduling strategy for search space pruning. The algorithm\\'s per-trajectory searches are independent of each other and can be performed in parallel, and the merging has constant cost. An empirical study with real data offers insight in the performance of the algorithm and demonstrates that is capable of outperforming a well-designed baseline algorithm by an order of magnitude.

    Venture, a kit airplane designed and manufactured by Questair, is a high performance lightplane with excellent low speed characteristics and enhanced safety due to NASA technology incorporated in its unusual wing design. In 1987, North Carolina State graduate students and Langley Research Center spent seven months researching and analyzing the Venture. The result was a wing modification, improving control and providing more usable lift. The plane subsequently set 10 world speed records.

    A dynamic quantum private comparison protocol based on the single photons in both polarization and spatial-mode degrees of freedom is proposed. In this protocol, any two parties of n( n ≥ 4) parties can compare their private information with the help of others n - 2 parties. And any party can join in the protocol to take part in the comparison of n parties. Correctness analysis shows that the proposed protocol can be used to compare their information correctly. Security analysis shows that the proposed protocol can resist the general active attacks from an outside eavesdropper. And it can overcomes the problem of information leakage.

    The pursuit of a high lift force for insect-scale flapping-wing micro aerial vehicles (FMAVs) requires that their artificial wings possess biomimetic wing features which are close to those of their natural counterpart. In this work, we present both fabrication and testing methods for artificial insect wings with biomimetic wing morphology and mechanical properties. The artificial cicada (Hyalessa maculaticollis) wing is fabricated through a high precision laser cutting technique and a bonding process of multilayer materials. Through controlling the shape of the wing venation, the fabrication method can achieve three-dimensional wing architecture, including cambers or corrugations. Besides the artificial cicada wing, the proposed fabrication method also shows a promising versatility for diverse wing types. Considering the artificial cicada wing's characteristics of small size and light weight, special mechanical testing systems are designed to investigate its mechanical properties. Flexural stiffness, maximum deformation rate and natural frequency are measured and compared with those of its natural counterpart. Test results reveal that the mechanical properties of the artificial cicada wing depend strongly on its vein thickness, which can be used to optimize an artificial cicada wing's mechanical properties in the future. As such, this work provides a new form of artificial insect wings which can be used in the field of insect-scale FMAVs.

    2005-06-01

    This report presents results of research on advanced joining techniques for ferritic oxide-dispersion strengthened alloys MA956 and PM2000. The joining techniques studied were resistance pressure welding (also known as pressure forge welding), transient liquid phase bonding, and diffusion bonding. All techniques were shown to produce sound joints in fine-grained, unrecrystallized alloys. Post-bond heat treatment to produce a coarse-grained, recrystallized microstructure resulted in grain growth across the bondline for transient liquid phase and diffusion bonds, giving microstructures essentially identical to that of the parent alloy in the recrystallized condition. The effects of bond orientation, boron interlayer thickness, and bonding parameters are discussed for transient liquid phase and diffusion bonding. The report concludes with a brief discussion of ODS joining techniques and their applicability to GEN IV reactor systems.

    Full Text Available The focus of this article is on how different parties use its party newspapers as instruments of political communication, in the current political context, particularly in Portuguese press. As is to be expected, the newspapers reproduce the party’s vision and help disseminate their leaders’ political ideals and proposals. There are, however, significant differences in the history and format of each publication, in terms of the way the political message is put across and the scope of the subjects addressed. This article is based on a content analysis technique, through a categorical qualitative and quantitative systematization. The expected results are centered on the discussion about the communication strategies of ideologically different party newspapers which are visible in front pages. Moreover, this study is expected to contribute to the discussion about personalization in politics, focusing and considering in particular party newspapers. This is a subject that has been scarcely investigated in communication studies and in political science, despite the presence and ideological place of party newspapers in the past and at present. The aim of this article is to make a contribution toward demonstrating and boosting the interest of this important support to party life and politics.

    2017-03-01

    We describe an approach for the discrete and reversible assembly of tunable and actively deformable structures using modular building block parts for robotic applications. The primary technical challenge addressed by this work is the use of this method to design and fabricate low density, highly compliant robotic structures with spatially tuned stiffness. This approach offers a number of potential advantages over more conventional methods for constructing compliant robots. The discrete assembly reduces manufacturing complexity, as relatively simple parts can be batch-produced and joined to make complex structures. Global mechanical properties can be tuned based on sub-part ordering and geometry, because local stiffness and density can be independently set to a wide range of values and varied spatially. The structure's intrinsic modularity can significantly simplify analysis and simulation. Simple analytical models for the behavior of each building block type can be calibrated with empirical testing and synthesized into a highly accurate and computationally efficient model of the full compliant system. As a case study, we describe a modular and reversibly assembled wing that performs continuous span-wise twist deformation. It exhibits high performance aerodynamic characteristics, is lightweight and simple to fabricate and repair. The wing is constructed from discrete lattice elements, wherein the geometric and mechanical attributes of the building blocks determine the global mechanical properties of the wing. We describe the mechanical design and structural performance of the digital morphing wing, including their relationship to wind tunnel tests that suggest the ability to increase roll efficiency compared to a conventional rigid aileron system. We focus here on describing the approach to design, modeling, and construction as a generalizable approach for robotics that require very lightweight, tunable, and actively deformable structures.

    2016-01-01

    This book presents the latest advances in mechanical and materials engineering applied to the machining, joining and modification of modern engineering materials. The contributions cover the classical fields of casting, forming and injection moulding as representative manufacturing methods, whereas additive manufacturing methods (rapid prototyping and laser sintering) are treated as more innovative and recent technologies that are paving the way for the manufacturing of shapes and features that traditional methods are unable to deliver. The book also explores water jet cutting as an innovative cutting technology that avoids the heat build-up typical of classical mechanical cutting. It introduces readers to laser cutting as an alternative technology for the separation of materials, and to classical bonding and friction stir welding approaches in the context of joining technologies. In many cases, forming and machining technologies require additional post-treatment to achieve the required level of surface quali...

  18. Fundamentals of metals joining with lasers

    Energy Technology Data Exchange (ETDEWEB)

    Jellison, J.L.

    1991-01-01

    The intrinsic characteristic of a laser as a metals joining heat source is high intensity (high irradiance). Other advantages stem from the ability to optically manipulate the beam and the inertness of light. Optimal application of laser technology to metals joining is supported by a fundamental understanding of the physics of the process. The interaction of the laser beam with metals is highly materials and process dependent. Metals joining with lasers in a absence of an understanding of beam-materials interactions would appear to be a highly unpredictable process. This is because of the complexity of beam-material interactions. For example, absorptivity varies by more than an order of magnitude as a function of alloy, temperature, oxide thickness, and laser wavelength. Also, in most laser welding and brazing processing, evaporation of metal creates a significant plume, and beam-plume interactions can markedly alter the spatial distribution of energy at the plume-metal interface. The probability of the beam being absorbed by the plume increases with the square of the wavelength, whereas the propensity for scattering of the beam by particles in the beam is inversely proportional to wavelength. Also, the beam can be refracted due to thermal and compositional gradients in the plume. In selecting a laser process for a given application, understanding each of these physical effects and others is helpful. In many ways, the physics of metals joining with lasers is only qualitatively understood at the present time. This paper overviews the present understanding of the process and identifies areas where research is required to clarify our process understanding.

    Wolkenstein, Fabio

    2016-01-01

    Contemporary scholarship on intra-party democracy pays a great deal of attention to aggregative procedures like primaries or membership ballots but widely ignores deliberative procedures within parties. This article begins by highlighting why scholars should care about deliberation within parties......, discussing several functions intra-party deliberation is said to serve in the democratic theory literature. It then goes on to explore the deliberative credentials of political discussion between party members, drawing on group interviews with party members in two Social Democratic parties in Germany...... and Austria. Two issues are investigated: the preconditions for deliberation among party members and their justificatory patterns. The results of the analysis suggest that parties can be genuine vehicles of deliberation, and thus point towards a research programme on intra-party democracy that differs quite...

  11. Agrarian Peasant Question as a Reflection of Ukrainian Parties Ideology at the Beginning of the 20th Century: Historiographic Discourse

    Directory of Open Access Journals (Sweden)

    Dmytro Kudinov

    2014-08-01

    Full Text Available The keenness and acuity of the agrarian and peasant question, which should be conceived as conscious problem of land scarcity, legal status of peasant social stratum, of peasant agrarians and peasant labourers made political parties at the beginning of the 20th century to work out their visions of crisis situation overcoming in the countryside. The necessity to be armed with own opinion on this matter concerned both Russian and national parties in the Russian Empire. The author suggests reviewing agrarian concepts of various parties as the measure of their referring to either to left wing or liberal political parties. Such concept statement is investigated in frames of historiographic discourse with involvement of original documents, which permits to make sense of the stated issue. The participants of the historiographic dialogue are mostly represented by contemporary scientists, who study the agrarian components of Ukrainian parties platforms at the beginning of the 20th century.

  15. Numerical Characterization of a Composite Bonded Wing-Box

    Smeltzer, Stanley S., III; Lovejoy, Andrew E.; Satyanarayana, Arunkumar

    2008-01-01

    The development of composite wing structures has focused on the use of mechanical fasteners to join heavily-loaded areas, while bonded joints have been used only for select locations. The focus of this paper is the examination of the adhesive layer in a generic bonded wing box that represents a "fastenerless" or unitized structure in order to characterize the general behavior and failure mechanisms. A global/local approach was applied to study the response of the adhesive layer using a global shell model and a local shell/solid model. The wing box was analyzed under load to represent a high-g up-bending condition such that the strains in the composite sandwich face sheets are comparable to an expected design allowable. The global/local analysis indicates that at these wing load levels the strains in the adhesive layer are well within the adhesive's elastic region, such that yielding would not be expected in the adhesive layer. The global/local methodology appears to be a promising approach to evaluate the structural integrity of the adhesively bonded structures.

    In this article we present a theoretical construction of spacetimes with a thin shell that joins two different local cosmic string geometries. We study two types of global manifolds, one representing spacetimes with a thin shell surrounding a cosmic string or an empty region with Minkowski metric, and the other corresponding to wormholes which are not symmetric across the throat located at the shell. We analyze the stability of the static configurations under perturbations preserving the cylindrical symmetry. For both types of geometries we find that the static configurations can be stable for suitable values of the parameters. (orig.)

    2011-01-01

    Objective Test the hypothesis that glass-bonding of free-form veneer and core ceramic layers can produce robust interfaces, chemically durable and aesthetic in appearance and, above all, resistant to delamination. Methods Layers of independently produced porcelains (NobelRondo™ Press porcelain, Nobel BioCare AB and Sagkura Interaction porcelain, Elephant Dental) and matching alumina or zirconia core ceramics (Procera alumina, Nobel BioCare AB, BioZyram yttria stabilized tetragonal zirconia polycrystal, Cyrtina Dental) were joined with designed glasses, tailored to match thermal expansion coefficients of the components and free of toxic elements. Scanning electron microprobe analysis was used to characterize the chemistry of the joined interfaces, specifically to confirm interdiffusion of ions. Vickers indentations were used to drive controlled corner cracks into the glass interlayers to evaluate the toughness of the interfaces. Results The glass-bonded interfaces were found to have robust integrity relative to interfaces fused without glass, or those fused with a resin-based adhesive. Significance The structural integrity of the interfaces between porcelain veneers and alumina or zirconia cores is a critical factor in the longevity of all-ceramic dental crowns and fixed dental prostheses.

    Full Text Available The increasing utilisation of different material groups (plastic, metal, ceramics in our advanced construction provides many benefits, but the fastening process is a challenge. LAMP (Laser assisted metal plastic joining is a new technique in fastening technology. It means an alternative process from the existing techniques like using adhesives, screwing, riveting etc. The authors have been dealing with this technology for years. In this research work some important thermal phenomena were analysed in order to understand the process of joining more thoroughly. The temperature of the steel partner was measured in case of different laser settings and experimental situations with two measuring techniques: thermocouple and infrared camera. The results show the effect of different influencing factors during heating and the applicability of different measuring methods. The received temperature values can be compared to the characteristic temperature of PMMA polymer (decomposition temperature in order to determine the root cause of bubble forming in the polymer material. From the result the differences between the different applied laser pulse mode for the heating was also determined and it was possible to measure the heating rate during the laser process.

    The objectives of this exploratory research were to (1) explore the characteristics and risks associated with college theme parties, (2) assess differences in risk associated with college theme parties compared to non-theme parties and (3) to assess differences in risk associated with risqué theme parties as compared to non-risqué theme parties. We used a mixed methods design. Results are presented from three exploratory studies of alcohol consumption in college theme parties: (1) four qualitative focus groups of students who have attended such events, (2) a web-based survey and (3) a multi-level (observational, survey, breath blood alcohol samples) study of 226 college parties, 29 of which were themed events. Focus group participants included a convenience sample of 17 college students aged 18-24 years; participants for the web survey included a convenience sample of 407 college students; participants for the multi-level study of college parties included 1725 randomly selected individuals at college parties. Themes tended to be highly sexualized. Compared to non-themed parties, theme parties have been observed to be more rowdy, louder, involve drinking games, feature kegs and feature hard liquor. Themed parties are associated with heavy drinking and are consistent with environments sought by heavy drinkers. As a result, themed parties are marked by a greater number of alcohol-related problems. Further research is needed to understand more clearly the risks involved in themed and risqué themed events.

  10. The Europeanisation of Slovak Political Parties

    Full Text Available The aim of the study is to analyse the Europeanisation of Slovak political parties in the various stages of the transition and transformation of the political system of Slovakia before and after the entry into the European Union. Methodologically, the paper is based on the concept of Ladrech, who divided five areas of research to suit the study of the impact of the Europeanisation on political parties and their politics. Visible can be changes in political programmes, organisational changes, a formula of party competition, relations between parties and government, relations beyond the national party system (a new look at transnational cooperation between political parties. Our research proved that the Europeanisation has been visible at all stages of development, with varying degrees of intensity and in various forms since the signing of the association agreement with the European Union. Its effect was important already in the stage of the society transition when it helped the return of Slovakia on the path of democratic development. In the two stages of development, Europeanisation created an individual line of cleavage of political parties, affected the rivalry of political parties, and thus a party system model. Unambiguously, it was reflected in political programmes of all parties, and an important role was played by the incorporation of political parties in the European political parties, by their cooperation and coordination of their policies. The election in the European Parliament was an important turning point in completion of programme orientations of political parties.

  11. Automated measurement of Drosophila wings

    Directory of Open Access Journals (Sweden)

    Mezey Jason

    2003-12-01

    Full Text Available Abstract Background Many studies in evolutionary biology and genetics are limited by the rate at which phenotypic information can be acquired. The wings of Drosophila species are a favorable target for automated analysis because of the many interesting questions in evolution and development that can be addressed with them, and because of their simple structure. Results We have developed an automated image analysis system (WINGMACHINE that measures the positions of all the veins and the edges of the wing blade of Drosophilid flies. A video image is obtained with the aid of a simple suction device that immobilizes the wing of a live fly. Low-level processing is used to find the major intersections of the veins. High-level processing then optimizes the fit of an a priori B-spline model of wing shape. WINGMACHINE allows the measurement of 1 wing per minute, including handling, imaging, analysis, and data editing. The repeatabilities of 12 vein intersections averaged 86% in a sample of flies of the same species and sex. Comparison of 2400 wings of 25 Drosophilid species shows that wing shape is quite conservative within the group, but that almost all taxa are diagnosably different from one another. Wing shape retains some phylogenetic structure, although some species have shapes very different from closely related species. The WINGMACHINE system facilitates artificial selection experiments on complex aspects of wing shape. We selected on an index which is a function of 14 separate measurements of each wing. After 14 generations, we achieved a 15 S.D. difference between up and down-selected treatments. Conclusion WINGMACHINE enables rapid, highly repeatable measurements of wings in the family Drosophilidae. Our approach to image analysis may be applicable to a variety of biological objects that can be represented as a framework of connected lines.

    The applicability of new nonlinear theoretical techniques is demonstrated for supersonic wing design. The new technology was utilized to define outboard panels for an existing advanced tactical fighter model. Mach 1.6 maneuver point design and multi-operating point compromise surfaces were developed and tested. High aerodynamic efficiency was achieved at the design conditions. A corollary result was that only modest supersonic penalties were incurred to meet multiple aerodynamic requirements. The nonlinear potential analysis of a practical configuration arrangement correlated well with experimental data.

    2011-12-01

    The present research focuses on the party related drinking behaviors of college students and explores the differences in these behaviors based on students' host status (i.e. party host vs. party attendee). Furthermore, we examine if the differences in party hosts and attendees' drinking behaviors vary as a function of the party location (on-campus vs. off-campus). Multiple regression analyses were conducted using data from 3796 undergraduates at a Midwestern University. Findings revealed a significant interaction between host status and party location, such that student party hosts reported significantly greater drink consumption and related consequences as compared to party attendees, only when the party was organized off-campus. For parties organized on-campus, student hosts reported lower drink consumption as compared to attendees. College-based preventive interventions should target students likely to host off-campus parties due to their high risk for involvement in heavy drinking. Copyright © 2011 Elsevier Ltd.

    An aircraft has wings configured to twist during flight. Inboard and outboard propulsion devices, such as turbofans or other propulsors, are connected to each wing, and are spaced along the wing span. A flight controller independently controls thrust of the inboard and outboard propulsion devices to significantly change flight dynamics, including changing thrust of outboard propulsion devices to twist the wing, and to differentially apply thrust on each wing to change yaw and other aspects of the aircraft during various stages of a flight mission. One or more generators can be positioned upon the wing to provide power for propulsion devices on the same wing, and on an opposite wing.

    Butterfly wings are live organs embedded with multiple sensory neurons and, in some species, with pheromoneproducing cells. The proper function of butterfly wings demands a suitable temperature range, but the wings can overheat quickly in the sun due to their small thermal capacity. We developed an infrared technique to map butterfly wing temperatures and discovered that despite the wings' diverse visible colors, regions of wings that contain live cells are the coolest, resulting from the thickness of the wings and scale nanostructures. We also demonstrated that butterflies use behavioral traits to prevent overheating of their wings.

    Wood, Richard M.; Bauer, Steven X. S.

    1992-01-01

    A wing-design study was conducted on a 65 degree swept leading-edge delta wing in which the wing geometry was modified to take advantage of the naturally occurring flow that forms over a slender wing in a supersonic flow field. Three-dimensional nonlinear analysis methods were used in the study which was divided into three parts: preliminary design, initial design, and final design. In the preliminary design, the wing planform, the design conditions, and the near-conical wing-design concept were derived, and a baseline standard wing (conventional airfoil distribution) and a baseline near-conical wing were chosen. During the initial analysis, a full-potential flow solver was employed to determine the aerodynamic characteristics of the baseline standard delta wing and to investigate modifications to the airfoil thickness, leading-edge radius, airfoil maximum-thickness position, and wing upper to lower surface asymmetry on the baseline near-conical wing. The final design employed an Euler solver to analyze the best wing configurations found in the initial design and to extend the study of wing asymmetry to develop a more refined wing. Benefits resulting from each modification are discussed, and a final 'natural flow' wing geometry was designed that provides an improvement in aerodynamic performance compared with that of a baseline conventional uncambered wing, linear-theory cambered wing, and near-conical wing.

  20. How Do Wings Generate Lift?

    Indian Academy of Sciences (India)

    lation viscosity is required. A wing is seen as a body that locally disturbs the otherwise uniform flow. The disturbances in veloc- ity and pressure caused are such that they aid to generate lift but damp down to zero far away from the wing. The momentum the- orem connects these ideas and explains how the reaction force to.

    The stiffness of insect wings is typically determined through experimental measurements. Such experiments are performed on wings removed from insects. However, the wings are subject to desiccation which typically leads to an increase in their stiffness. Although this effect of desiccation is well known, a comprehensive study of the rate of change in stiffness of desiccating insect wings would be a significant aid in planning experiments as well as interpreting data from such experiments. This communication presents a comprehensive experimental analysis of the change in mass and stiffness of gradually desiccating forewings of Painted Lady butterflies (Vanessa cardui). Mass and stiffness of the forewings of five butterflies were simultaneously measured every 10 min over a 24 h period. The averaged results show that wing mass declined exponentially by 21.1% over this time period with a time constant of 9.8 h, while wing stiffness increased linearly by 46.2% at a rate of 23.4 {mu}N mm{sup -1} h{sup -1}. For the forewings of a single butterfly, the experiment was performed over a period of 1 week, and the results show that wing mass declined exponentially by 52.2% with a time constant of 30.2 h until it reached a steady-state level of 2.00 mg, while wing stiffness increased exponentially by 90.7% until it reached a steady-state level of 1.70 mN mm{sup -1}.

  19. Beetle wings are inflatable origami

    Science.gov (United States)

    Chen, Rui; Ren, Jing; Ge, Siqin; Hu, David

    2015-11-01

    Beetles keep their wings folded and protected under a hard shell. In times of danger, they must unfold them rapidly in order for them to fly to escape. Moreover, they must do so across a range of body mass, from 1 mg to 10 grams. How can they unfold their wings so quickly? We use high-speed videography to record wing unfolding times, which we relate to the geometry of the network of blood vessels in the wing. Larger beetles have longer unfolding times. Modeling of the flow of blood through the veins successfully accounts for the wing unfolding speed of large beetles. However, smaller beetles have anomalously short unfolding times, suggesting they have lower blood viscosity or higher driving pressure. The use of hydraulics to unfold complex objects may have implications in the design of micro-flying air vehicles.

  20. AERODYNAMICS OF WING TIP SAILS

    2006-06-01

    Full Text Available Observers have always been fascinated by soaring birds. An interesting feature of these birds is the existence of few feathers extending from the tip of the wing. In this paper, small lifting surfaces were fitted to the tip of a NACA0012 wing in a fashion similar to that of wing tip feathers. Experimental measurements of induced drag, longitudinal static stability and trailing vortex structure were obtained.The tests showed that adding wing tip surfaces (sails decreased the induced drag factor and increased the longitudinal static stability. Results identified two discrete appositely rotated tip vortices and showed the ability of wing tip surfaces to break them down and to diffuse them.

  7. Insect wing membrane topography is determined by the dorsal wing epithelium.

    Science.gov (United States)

    Belalcazar, Andrea D; Doyle, Kristy; Hogan, Justin; Neff, David; Collier, Simon

    2013-01-01

    The Drosophila wing consists of a transparent wing membrane supported by a network of wing veins. Previously, we have shown that the wing membrane cuticle is not flat but is organized into ridges that are the equivalent of one wing epithelial cell in width and multiple cells in length. These cuticle ridges have an anteroposterior orientation in the anterior wing and a proximodistal orientation in the posterior wing. The precise topography of the wing membrane is remarkable because it is a fusion of two independent cuticle contributions from the dorsal and ventral wing epithelia. Here, through morphological and genetic studies, we show that it is the dorsal wing epithelium that determines wing membrane topography. Specifically, we find that wing hair location and membrane topography are coordinated on the dorsal, but not ventral, surface of the wing. In addition, we find that altering Frizzled Planar Cell Polarity (i.e., Fz PCP) signaling in the dorsal wing epithelium alone changes the membrane topography of both dorsal and ventral wing surfaces. We also examined the wing morphology of two model Hymenopterans, the honeybee Apis mellifera and the parasitic wasp Nasonia vitripennis. In both cases, wing hair location and wing membrane topography are coordinated on the dorsal, but not ventral, wing surface, suggesting that the dorsal wing epithelium also controls wing topography in these species. Because phylogenomic studies have identified the Hymenotera as basal within the Endopterygota family tree, these findings suggest that this is a primitive insect character.

  8. The niche party concept and its measurement.

    Science.gov (United States)

    Meyer, Thomas M; Miller, Bernhard

    2015-03-01

    The concept of the niche party has become increasingly popular in analyses of party competition. Yet, existing approaches vary in their definitions and their measurement approaches. We propose using a minimal definition that allows us to compare political parties in terms of their 'nicheness'. We argue that the conceptual core of the niche party concept is based on issue emphasis and that a niche party emphasizes policy areas neglected by its rivals. Based on this definition, we propose a continuous measure that allows for more fine-grained measurement of a party's 'nicheness' than the dominant, dichotomous approaches and thereby limits the risk of measurement error. Drawing on data collected by the Comparative Manifesto Project, we show that (1) our measure has high face validity and (2) exposes differences among parties that are not captured by alternative, static or dichotomous measures.

  11. Evaluating the Upset Protrusion Joining (UPJ) Method to Join Magnesium Castings to Dissimilar Metals

    Energy Technology Data Exchange (ETDEWEB)

    Logan, Stephen [FCA US LLC, Auburn Hills, MI (United States)

    2016-02-24

    This presentation discusses advantages and best practices for incorporating magnesium in automotive component applications to achieve substantial mass reduction, as well as some of the key challenges with respect to joining, coating, and galvanic corrosion, before providing an introduction and status update of the U.S. Department of Energy and Department of Defense jointly sponsored Upset Protrusion Joining (UPJ) process development and evaluation project. This update includes sharing performance results of a benchmark evaluation of the self-pierce riveting (SPR) process for joining dissimilar magnesium (Mg) to aluminum (Al) materials in four unique coating configurations before introducing the UPJ concept and comparing performance results of the joints made with the UPJ process to those made with the SPR process. Key results presented include: The benchmark SPR process can produce good joints in the MgAM60B-Al 6013 joint configuration with minimal cracking in the Mg coupons if the rivet is inserted from the Mg side into the Al side; Numerous bare Mg to bare Al joints made with the SPR process separated after only 6-wks of accelerated corrosion testing due to fracture of the rivet as a result of hydrogen embrittlement; For the same joint configurations, UPJ demonstrated substantially higher pre-corrosion joint strengths and post-corrosion joint strengths, primarily because of the larger diameter protrusion compared to smaller SPR rivet diameter and reduced degradation due to accelerated corrosion exposure; As with the SPR process, numerous bare Mg to bare Al joints made with the UPJ process also separated after 6-wks of accelerated corrosion testing, but unlike the SPR experience, the UPJ joints experienced degradation of the boss and head because of galvanic corrosion of the Mg casting, not hydrogen embrittlement of the steel rivet; In the configuration where both the Mg and Al were pretreated with Alodine 5200 prior to joining and the complete assembly was powder

  12. Wing rotation and lift in SUEX flapping wing mechanisms

    Mateti, Kiron; Byrne-Dugan, Rory A.; Tadigadapa, Srinivas A.; Rahn, Christopher D.

    2013-01-01

    This research presents detailed modeling and experimental testing of wing rotation and lift in the LionFly, a low cost and mass producible flapping wing mechanism fabricated monolithically from SUEX dry film and powered by piezoelectric bimorph actuators. A flexure hinge along the span of the wing allows the wing to rotate in addition to flapping. A dynamic model including aerodynamics is developed and validated using experimental testing with a laser vibrometer in air and vacuum, stroboscopic photography and high definition image processing, and lift measurement. The 112 mg LionFly produces 46° flap and 44° rotation peak to peak with 12° phase lag, which generates a maximum average lift of 71 μN in response to an applied sinusoidal voltage of 75 V AC and 75 V DC at 37 Hz. Simulated wing trajectories accurately predict measured wing trajectories at small voltage amplitudes, but slightly underpredict amplitude and lift at high voltage amplitudes. By reducing the length of the actuator, reducing the mechanism amplification and tuning the rotational hinge stiffness, a redesigned device is simulated to produce a lift to weight ratio of 1.5.

    Full Text Available Après octobre 1988 et la mise en place d’une « nouvelle formule politique » qui consacre le pluripartisme, l’identité berbère devient en Algérie, un enjeu majeur des stratégies partisanes de deux partis : le Front des forces socialistes et le Rassemblement pour la culture et la démocratie. Le premier est ancien et a participé à l’émergence dans les années 1980 du Mouvement culturel berbère. Le second est issu de ce mouvement et s’institutionnalise en parti à la faveur de l’instauration du multipartisme en 1989. L’analyse porte donc sur les stra­tégies identitaires déployées par ces deux formations rivales. Concurrentes auprès des autorités publiques et en termes d’ancrage territorial, elles déploient un discours culturaliste et localiste bien qu’elles se situent dans le champ politique national. Réalisée à la fin des années 1990, elle questionne en dernier ressort les diverses attitudes adoptées par ces entrepreneurs politiques berbéristes aux buttes aux pièges de l’enfermement régional et ethnique : dans quelle mesure peuvent-elles dépasser ce cadre régional et constituer une alternative démocratique viable en Algérie ?

  14. Weather conditions and political party vote share in Dutch national parliament elections, 1971-2010

    Science.gov (United States)

    Eisinga, Rob; Te Grotenhuis, Manfred; Pelzer, Ben

    2012-11-01

    Inclement weather on election day is widely seen to benefit certain political parties at the expense of others. Empirical evidence for this weather-vote share hypothesis is sparse however. We examine the effects of rainfall and temperature on share of the votes of eight political parties that participated in 13 national parliament elections, held in the Netherlands from 1971 to 2010. This paper merges the election results for all Dutch municipalities with election-day weather observations drawn from all official weather stations well distributed over the country. We find that the weather parameters affect the election results in a statistically and politically significant way. Whereas the Christian Democratic party benefits from substantial rain (10 mm) on voting day by gaining one extra seat in the 150-seat Dutch national parliament, the left-wing Social Democratic (Labor) and the Socialist parties are found to suffer from cold and wet conditions. Cold (5°C) and rainy (10 mm) election day weather causes the latter parties to lose one or two parliamentary seats.

    A comparative evaluation of fixed-geometry and variable-sweep wing designs, a fixed delta wing, and oblique wings with a single body or two bodies suggests that an oblique wing is preferable in a transonic transport aircraft in terms of gross weight, fuel consumption, and aircraft noise, and also shows an acceptable aeroelastic stability. Further studies are, however, needed to develop the full potential of the oblique-wing concept, including its economic implications.

    Friese, Bettina; Grube, Joel W

    2014-12-01

    This study explores which youth are more likely to have parties at home, what factors are associated with the presence of alcohol at parties, and who supplies the alcohol. We collected data in 2011 and 2012 through telephone interviews with 1,121 teens living in 50 mid-sized California cities. Overall, about a quarter of teens reported having had a party at their house in the past 12 months, of whom 39 % reported that there was alcohol at their last party. Multiple sources supplied alcohol for most parties. Seventy-two percent of those having a party stated that at least one of their parents knew about their last party, and 64 % reported that a parent was home at least part of the time. Seventy percent of youth who hosted a party with alcohol said that their parent(s) definitely knew that there was alcohol at the party, 24 % replied that their parent(s) probably knew, and only 5 % said that their parent(s) did not know that there was alcohol at the party. Logistic regression analyses indicated that youth with parents who host parties at home are themselves more likely to host parties at home. Having alcohol at a party was positively related to the age of the teen and the number of guests attending, and was negatively related to parents' awareness of the party. However, we found no relationship between whether a parent was at home at the time of the party and whether it included alcohol. These findings suggest that teens who have parties with alcohol at home have parents who know that there is alcohol at the party, even though only a small number of parents provided alcohol for the party.

  19. Drag Performance of Twist Morphing MAV Wing

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Morphing wing is one of latest evolution found on MAV wing. However, due to few design problems such as limited MAV wing size and complicated morphing mechanism, the understanding of its aerodynamic behaviour was not fully explored. In fact, the basic drag distribution induced by a morphing MAV wing is still remained unknown. Thus, present work is carried out to compare the drag performance between a twist morphing wing with membrane and rigid MAV wing design. A quasi-static aeroelastic analysis by using the Ansys-Fluid Structure Interaction (FSI method is utilized in current works to predict the drag performance a twist morphing MAV wing design. Based on the drag pattern study, the results exhibits that the morphing wing has a partial similarities in overall drag pattern with the baseline (membrane and rigid wing. However, based CD analysis, it shows that TM wing induced higher CD magnitude (between 25% to 82% higher than to the baseline wing. In fact, TM wing also induced the largest CD increment (about 20% to 27% among the wings. The visualization on vortex structure revealed that TM wing also produce larger tip vortex structure (compared to baseline wings which presume to promote higher induce drag component and subsequently induce its higher CD performance.

    Non-homologous end joining (NHEJ) is the dominant DNA double strand break (DSB) repair pathway and involves several NHEJ proteins such as Ku, DNA-PKcs, XRCC4, Ligase IV and so on. Once DSBs are generated, Ku is first recruited to the DNA end, followed by other NHEJ proteins for DNA end processing and ligation. Because of the direct ligation of break ends without the need for a homologous template, NHEJ turns out to be an error-prone but efficient repair pathway. Some mechanisms have been proposed of how the efficiency of NHEJ repair is affected. The type of DNA damage is an important factor of NHEJ repair. For instance, the length of DNA fragment may determine the recruitment efficiency of NHEJ protein such as Ku [1], or the complexity of the DNA breaks [2] is accounted for the choice of NHEJ proteins and subpathway of NHEJ repair. On the other hand, the chromatin structure also plays a role of the accessibility of NHEJ protein to the DNA damage site. In this talk, some mathematical models of NHEJ, that consist of series of biochemical reactions complying with the laws of chemical reaction (e.g. mass action, etc.), will be introduced. By mathematical and numerical analysis and parameter estimation, the models are able to capture the qualitative biological features and show good agreement with experimental data. As conclusions, from the viewpoint of modeling, how the NHEJ proteins are recruited will be first discussed for connection between the classical sequential model [4] and recently proposed two-phase model [5]. Then how the NHEJ repair pathway is affected, by the length of DNA fragment [6], the complexity of DNA damage [7] and the chromatin structure [8], will be addressed

    One challenge in adapting welding processes to dissimilar material joining is the diversity of melting temperatures of the different materials. Although the use of mechanical fasteners and adhesives have mostly paved the way for near-term implementation of dissimilar material systems, these processes only accentuate the need for low-cost welding processes capable of joining dissimilar material components regardless of alloy, properties, or melting temperature. Friction stir scribe technology was developed to overcome the challenges of joining dissimilar material components where melting temperatures vary greatly, and properties and/or chemistry are not compatible with more traditional welding processes. Although the friction stir scribe process is capable of joining dissimilar metals and metal/polymer systems, a more detailed evaluation of several aluminum/steel joints is presented herein to demonstrate the ability to both chemically and mechanically join dissimilar materials.

    1991-01-01

    A scissor-wing configuration, consisting of two independently sweeping-wing surfaces, is compared with an equivalent fixed-wing geometry baseline over a wide Mach number range. The scissor-wing configuration is shown to have a higher total lift-to-drag ratio than the baseline in the subsonic region primarily due to the slightly higher aspect ratio of the unswept scissor wing. In the transonic region, the scissor wing is shown to have a higher lift-to-drag ratio than the baseline for values of lift coefficient greater than 0.35. It is also shown that, through the use of wing decalage, the lift of the two independent scissor wings can be equalized. In the supersonic regime, the zero lift wave drag of the scissor-wing at maximum sweep is shown to be 50 and 28 percent less than the zero lift wave drag of the baseline at Mach numbers 1.5 and 3.0, respectively. In addition, a pivot-wing configuration is introduced and compared with the scissor wing. The pivot-wing configuration is shown to have a slightly higher total lift-to-drag ratio than the scissor wing in the supersonic region due to the decreased zero lift wave drag of the pivot-wing configuration.

  15. How to hold an ethical pox party.

    Science.gov (United States)

    Jamrozik, Euzebiusz

    2017-10-25

    Pox parties are a controversial alternative to vaccination for diseases such as chickenpox. Such parties involve parents infecting non-immune children by exposing them to a contagious child. If successful, infection will usually lead to immunity, thus preventing infection later in life, which, for several vaccine-preventable diseases, is more severe than childhood infection. Some may consider pox parties more morally objectionable than opting out of vaccination through non-medical exemptions. In this paper, I argue that this is not the case. Pox parties involve immediate risk of harm for children and reduce future harms, whereas opting out of vaccination places children at long-term risk of harms that increase with time, at least for some pathogens. Regarding harm to others through onward transmission of infection, this can be easily prevented in the case of pox parties-given the relatively controlled timing of infection-by quarantining attendees after the party, whereas opting out of vaccination involves risks to others that are more difficult to control. I defend three criteria for an ethical pox party: (1) that the disease is sufficiently low risk, (2) that parents consent to their child's attendance and (3) that children exposed to infection are quarantined and isolated appropriately. I argue that, if these criteria are met, pox parties are morally preferable to non-vaccination; such parties involve less risk to non-consenting others and, for some pathogens in some cases, even involve less risk for the children who participate. Thus, policies that permit non-medical exemption to vaccination should also permit ethical pox parties. Alternatively, if pox parties are not permitted, then vaccination should be mandated for those without medical contraindication. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  16. Solid State Joining of Dissimilar Titanium Alloys

    Science.gov (United States)

    Morton, Todd W.

    Solid state joining of titanium via friction stir welding and diffusion bonding have emerged as enablers of efficient monolithic structural designs by the eliminations fasteners for the aerospace industry. As design complexity and service demands increase, the need for joints of dissimilar alloys has emerged. Complex thermomechanical conditions in friction stir weld joints and high temperature deformation behavior differences between alloys used in dissimilar joints gives rise to a highly variable flow pattern within a stir zone. Experiments performed welding Ti-6Al-4V to beta21S show that mechanical intermixing of the two alloys is the primary mechanism for the generation of the localized chemistry and microstructure, the magnitude of which can be directly related to pin rotation and travel speed weld parameters. Mechanical mixing of the two alloys is heavily influenced by strain rate softening phenomena, and can be used to manipulate weld nugget structure by switching which alloy is subjected to the advancing side of the pin. Turbulent mixing of a weld nugget and a significant reduction in defects and weld forces are observed when the beta21S is put on the advancing side of the weld where higher strain rates are present. Chemical diffusion driven by the heat of weld parameters is characterized using energy dispersive x-ray spectroscopy (EDS) and is shown to be a secondary process responsible for generating short-range chemical gradients that lead to a gradient of alpha particle structures. Diffusion calculations are inconsistent with an assumption of steady-state diffusion and show that material interfaces in the weld nugget evolve through the break-down of turbulent interface features generated by material flows. A high degree of recrystallization is seen throughout the welds, with unique, hybrid chemistry grains that are generated at material interfaces in the weld nugget that help to unify the crystal structure of dissimilar alloys. The degree of

  18. A Modeling Approach for Plastic-Metal Laser Direct Joining

    Science.gov (United States)

    Lutey, Adrian H. A.; Fortunato, Alessandro; Ascari, Alessandro; Romoli, Luca

    2017-09-01

    Laser processing has been identified as a feasible approach to direct joining of metal and plastic components without the need for adhesives or mechanical fasteners. The present work sees development of a modeling approach for conduction and transmission laser direct joining of these materials based on multi-layer optical propagation theory and numerical heat flow simulation. The scope of this methodology is to predict process outcomes based on the calculated joint interface and upper surface temperatures. Three representative cases are considered for model verification, including conduction joining of PBT and aluminum alloy, transmission joining of optically transparent PET and stainless steel, and transmission joining of semi-transparent PA 66 and stainless steel. Conduction direct laser joining experiments are performed on black PBT and 6082 anticorodal aluminum alloy, achieving shear loads of over 2000 N with specimens of 2 mm thickness and 25 mm width. Comparison with simulation results shows that consistently high strength is achieved where the peak interface temperature is above the plastic degradation temperature. Comparison of transmission joining simulations and published experimental results confirms these findings and highlights the influence of plastic layer optical absorption on process feasibility.

    A method of joining at least two parts includes steps of dispersing a joining material comprising a multi-phase magnetic metal-aluminum powder at an interface between the at least two parts to be joined and applying an alternating magnetic field (AMF). The AMF has a magnetic field strength and frequency suitable for inducing magnetic hysteresis losses in the metal-aluminum powder and is applied for a period that raises temperature of the metal-aluminum powder to an exothermic transformation temperature. At the exothermic transformation temperature, the metal-aluminum powder melts and resolidifies as a metal aluminide solid having a non-magnetic configuration.

    Full Text Available This paper is focused on innovative cold joining technologies for connecting tubes and fixing tubes to sheets. The proposed technologies are based on the utilization of plastic instability waves in thin-walled tubes subjected to axial compression and may be seen as an alternative to conventional joining technologies based on mechanical fixing with fasteners, welding and structural adhesive bonding. Besides allowing connecting dissimilar materials and being successfully employed in fixture conditions that are difficult and costly to achieve by means of conventional joining the new proposed technologies also cope with the growing concerns on the demand, lifecycle and recycling of materials.

    This article theorises and empirically assesses some important intra-organisational implications of maximising democratic equality in political parties both between followers and members and between members and elites. They include weak member commitment, passivity of the rank-and-file membership...... and – depending on party structure – high levels of internal conflict. To substantiate the arguments, two parties that implement principles of democratic equality in their organisations are examined: the Swedish and German Pirate parties. These cases show, first, that while organisational structures implementing...... norms of equality allowed them to rapidly mobilise a considerable following, the same structures systematically reduced their capacity to consolidate support in the longer term – a weakness that might eventually put these parties' survival at risk. Second, they show that differences in the extent...

    A new telescope, the Australian Square Kilometre Array Pathfinder (ASKAP), has joined the search for energetic and elusive fast radio bursts. And in just a few days of looking, its already had success!Elusive TransientsThe Parkes radio telescope, which has detected all but five of the fast radio bursts published to date, has a very narrow field of view. [CSIRO]Fast radio bursts are mysterious millisecond-duration radio pulses that were first discovered around a decade ago. Since that time particularly in recent years weve made some progress toward the goal of localizing them. Were now fairly convinced that fast radio bursts come from outside of the galaxy, and yet theyre enormously bright orders of magnitude more luminous than any pulse seen from the Milky Way.Better identification of where these mysterious bursts come from would help us to determine what they are. But so far, weve discovered only around 30 such bursts, despite the fact that theyre estimated to occur at a rate of 3,000 events per day across the whole sky.Why are they so hard to find? Due to their short duration, effective detection would require instantaneous coverage of a very large fraction of the sky. The Parkes radio telescope which has detected all but five of the fast radio bursts published to date has a field of view spanning less than a square degree,significantly limiting our ability to rapidly survey for these transients.FRB 170107s band-averaged pulse (top) and dynamic spectrum (bottom). [Bannister et al. 2017]A New Array in TownA new player is now on the scene, however, and its already had huge success. ASKAP is a wide-field radio telescope made up of an array of 12-meter antennas. Using phased-array-feed technology, ASKAP is able to instantaneously observe an effective area of 160 square degrees an enormous field compared to Parkes 0.6 square degrees! This capability significantly increases our chances of being able to detect fast radio bursts.In a new study led by Keith Bannister

    1993-01-01

    The provisions of this project call for the design of the structure of the wing and carry-through structure for the Viper primary trainer, which is to be certified as a utility category trainer under FAR part 23. The specific items to be designed in this statement of work were Front Spar, Rear Spar, Aileron Structure, Wing Skin, and Fuselage Carry-through Structure. In the design of these parts, provisions for the fuel system, electrical system, and control routing were required. Also, the total weight of the entire wing planform could not exceed 216 lbs. Since this aircraft is to be used as a primary trainer, and the SOW requires a useful life of 107 cycles, it was decided that all of the principle stresses in the structural members would be kept below 10 ksi. The only drawback to this approach is a weight penalty.

    Full Text Available Until now there has been a dearth of qualitative research on right-wing extremist organizations. We know little about the daily routines of "doing politics" in these specific life-worlds. There is also little research concerning the gendered substructure of right-wing extremist parties. Many of the studies that have been done focus on women's roles in such organizations, but the vast majority of its members and supporters, namely men, are seldom analyzed. In his excellent study, Oliver GEDEN explores a rather difficult field of research, examining in which way one of the most successful right-wing extremist parties in Europe, the Freedom Party of Austria, is constructing masculinity. GEDEN not only analyzes the masculinity discourse in two party periodicals, he also conducts group discussions with party officials in order to reconstruct what masculinity means to them in their everyday lives. Furthermore, he reflects about the specific conditions of doing qualitative research on right-wing extremist organizations, particularly on the handling of access restrictions and the requirements of research ethics.

  6. Aerodynamic control with passively pitching wings

    Science.gov (United States)

    Gravish, Nick; Wood, Robert

    Flapping wings may pitch passively under aerodynamic and inertial loads. Such passive pitching is observed in flapping wing insect and robot flight. The effect of passive wing pitch on the control dynamics of flapping wing flight are unexplored. Here we demonstrate in simulation and experiment the critical role wing pitching plays in yaw control of a flapping wing robot. We study yaw torque generation by a flapping wing allowed to passively rotate in the pitch axis through a rotational spring. Yaw torque is generated through alternating fast and slow upstroke and and downstroke. Yaw torque sensitively depends on both the rotational spring force law and spring stiffness, and at a critical spring stiffness a bifurcation in the yaw torque control relationship occurs. Simulation and experiment reveal the dynamics of this bifurcation and demonstrate that anomalous yaw torque from passively pitching wings is the result of aerodynamic and inertial coupling between the pitching and stroke-plane dynamics.

    Potential applications of SiC include components for advanced turbine engines, tube assemblies for radiant burners and petrochemical processing and heat exchangers for high efficiency electric power generation systems. Reliable methods for joining SiC are required in order to cost-effectively fabricate components for these applications from commercially available shapes and sizes. This manuscript reports the results of microwave joining experiments performed using two different types of SiC materials. The first were on reaction bonded SiC, and produced joints with fracture toughness equal to or greater than that of the base material over an extended range of joining temperatures. The second were on continuous fiber-reinforced SiC/SiC composite materials, which were successfully joined with a commercial active brazing alloy, as well as by using a polymer precursor.

  8. Study on the Hinge-joined Plate Method

    Full Text Available In order to verify and perfect the theory of hinge-joined plate method and make it serve the bridge design better, this paper was written based on an actual bridge, and the ANSYS finite element model was established. Compared the hinge-joined plate method results with the analysis results and through the investigation and data analysis, it could be found that the assumption that the hinge-joined plate theory for the board lateral force transmission is reasonable, but the assuming hinge joints that only withstand shear stress and just have the shear checking is unreasonable. At the same time, this paper also proved that the strength reduction getting from the old and new concrete interface should be taken into account when using the hinge-joined plate method to calculate the transverse distribution coefficient and the effects on overall stiffness that the joint depth and thickness of deck pavement to the beam bridge.

    The main objective of this project was to develop reliable, low-cost techniques for joining silicon nitride (Si{sub 3}N{sub 4}) to itself and to metals. For Si{sub 3}N{sub 4} to be widely used in advanced turbomachinery applications, joining techniques must be developed that are reliable, cost-effective, and manufacturable. This project addressed those needs by developing and testing two Si{sub 3}N{sub 4} joining systems; oxynitride glass joining materials and high temperature braze alloys. Extensive measurements were also made of the mechanical properties and oxidation resistance of the braze materials. Finite element models were used to predict the magnitudes and positions of the stresses in the ceramic regions of ceramic-to-metal joints sleeve and butt joints, similar to the geometries used for stator assemblies.

    This article analyses what makes political candidates run a party-focused or personalised election campaign. Prior work shows that candidates face incentives from voters and the media to personalise their campaign rhetoric and promises at the expense of party policy. This has raised concerns about...... the capacity of parties to govern effectively and voters’ ability to hold individual politicians accountable. This article builds on the literature on party organisation and considers the possible constraints candidates face from their party in personalising their election campaigns. Specifically, we argue...... that party control over the candidate nomination process and campaign financing constrains most political candidates in following electoral incentives for campaign personalisation.

  18. Mediterranean Left-Wing Populism: The Case of SYRIZA

    2017-04-01

    Full Text Available Until recently the increasing impact of the right-wing populist parties in Europe was quite impressing. Several of these parties gained significant electoral power but expediently they collapsed while others were consecrated electorally. With SYRIZA’s electoral victory in Greece, the emergence of PODEMOS in Spain and of the Five Star Movement in Italy - which includes several aspects of a left-wing populism - and the coalition between social-democrats and radical left in Portugal, the creation of a peculiar left populism has been evolved, especially in the Mediterranean part of Europe. High electoral percentages and consequently, their involvement in government through partisan organization professionalism and charismatic leadership, are main characteristics of these parties. Another crucial factor, regardless of their ideological roots, is the anti-European rhetoric, even if it existed only for some period in the past. For instance, SYRIZA in Greece, intensely criticized the present European structure but at the same time promised that Greece will remain to the EU and the Eurozone. Furthermore, it appeared as a political entity that promised, with a demagogic way, to overcome the obvious principle of state continuation, by denying to implement the agreement that the previous governments have signed with Greece’s partners. Eventually, this promise was converted into a trap as left-wing SYRIZA in government, was finally succumbed to the strong demand for adherence and implementation of all the previous agreements. Thus, SYRIZA failed both ideologically and practically. Apart from the diverse ideological and political illusions that characterize this type of populism, another characteristic is the deficit in specific policy substance. This deficit has been transformed into a large gap in terms of strategic program priorities and options. Thus, it turns out that SYRIZA’s rise to power was based on versatility and on a high degree of classless

    Dragonfly wings are highly corrugated, which increases the stiffness and strength of the wing significantly, and results in a lightweight structure with good aerodynamic performance. How insect wings carry aerodynamic and inertial loads, and how the resonant frequency of the flapping wings is tuned for carrying these loads, is however not fully understood.

  1. Of "Cocktail Parties" and Exoplanets

    Waldmann, I. P.

    2012-03-01

    The characterization of ever smaller and fainter extrasolar planets requires an intricate understanding of one's data and the analysis techniques used. Correcting the raw data at the 10-4 level of accuracy in flux is one of the central challenges. This can be difficult for instruments that do not feature a calibration plan for such high precision measurements. Here, it is not always obvious how to de-correlate the data using auxiliary information of the instrument and it becomes paramount to know how well one can disentangle instrument systematics from one's data, given nothing but the data themselves. We propose a non-parametric machine learning algorithm, based on the concept of independent component analysis, to de-convolve the systematic noise and all non-Gaussian signals from the desired astrophysical signal. Such a "blind" signal de-mixing is commonly known as the "Cocktail Party problem" in signal processing. Given multiple simultaneous observations of the same exoplanetary eclipse, as in the case of spectrophotometry, we show that we can often disentangle systematic noise from the original light-curve signal without the use of any complementary information of the instrument. In this paper, we explore these signal extraction techniques using simulated data and two data sets observed with the Hubble Space Telescope NICMOS instrument. Another important application is the de-correlation of the exoplanetary signal from time-correlated stellar variability. Using data obtained by the Kepler mission we show that the desired signal can be de-convolved from the stellar noise using a single time series spanning several eclipse events. Such non-parametric techniques can provide important confirmations of the existent parametric corrections reported in the literature, and their associated results. Additionally they can substantially improve the precision exoplanetary light-curve analysis in the future.

    Development of robust and cost effective method of joining dissimilar materials can provide a critical pathway to enable widespread use of multi-material design and components in mainstream industrial applications. The use of multi-material components such as Steel-Aluminum, Aluminum-Polymer allows design engineers to optimize material utilization based on service requirements and often lead weight and cost reductions. However producing an effective joint between materials with vastly different thermal, microstructural and deformation response is highly problematic using conventional joining and /or fastening methods. This is especially challenging in cost sensitive high volume markets that largely rely on low–cost joining solutions. Friction Stir Scribe technology was developed to meet the demands of joining materials with drastically different properties and melting regimes. The process enables joining of light metals like Magnesium and Aluminum to high temperature materials like Steels and Titanium. Additionally viable joints between polymer composites and metal can also be made using this method. This paper will present state of the art, progress made and challenges associated with this innovative derivative of Friction Stir welding in reference to joining dissimilar metals and polymer/metal combinations.

    Full Text Available The Joint International Forum of Political Parties, Think Tanks and NonGovernmental Organizations of the BRICS took place in Fuzhou, China on 10–12 June 2017. The event was hosted jointly by the International Department of the Central Committee of the Communist Party of China, the China Council for BRICS Think Tank Cooperation and the China NGO Network for International Exchanges.For the first time in the story of BRICS cooperation the countries’ representatives witnessed the renewed format of the BRICS Academic Forum – two traditional tracks (academic conference and civil track were supplemented by the assembly of political parties. Taking its turn in chairing the multinational BRICS association in 2017, China proposed this new Forum format and joined together three dialogues that had grown out of the BRICS Academic Forum, which took place now for the ninth time.1 Another innovation on China’s part was the outreach format – representatives of 28 countries, including Indonesia, Malaysia, the Philippines, Cambodia, Egypt, Nigeria, Ethiopia, Kenya, Argentina, Chile and Mexico among others took part.The Joint International Forum was a truly large-scale international event – 37 political parties of 26 countries, 105 think tanks, and over 400 representatives of 79 civil society organizations were in attendance.2The Forum participants engaged in separate deliberations at the BRICS Academic Forum on “Pooling Wisdom and New Ideas for Cooperation,” the BRICS Civil Society Organizations Forum on “Stronger People-to-People Bond for Better Cooperation,” and the BRICS Political Parties Dialogue on the “Guiding Role of Political Parties in Promoting Cooperation.” The Forum was a complete success with broad consensus.

    Fuchs, Alexander N.; Wirth, Franz X.; Rinck, Philipp; Zaeh, Michael F.

    Structural lightweight construction is increasingly utilized in the aerospace and automotive industry. Hybrid structures have great potential, especially with regard to load-specific component layouts. Usually, a surface pre-treatment is applied prior to joining dissimilar materials to improve bonding mechanisms such as form closure. In previous studies pulsed wave (pw) lasers were used for structuring metals. This paper presents the results of aluminum pre-treatment via a continuous wave (cw) single-mode fiber laser: macroscopic and microscopic structures were generated on the aluminum surface; the samples were joined with glass fiber reinforced polyamide using Friction Press Joining (FPJ), a method for joining metals and thermoplastic polymers in lap joint configuration. Using these new methods for surface structuring, shear strength was increased by 40% compared to previous studies with pw lasers.

  15. Parties heed (with caution): Public knowledge of and attitudes towards party finance in Britain.

    Science.gov (United States)

    vanHeerde-Hudson, Jennifer; Fisher, Justin

    2013-01-01

    Despite comprehensive reform (Political Parties, Elections and Referendums Act) and recent review (Phillips Review in 2007) of party finance in Britain, public opinion of party finance remains plagued by perceptions of corruption, undue influence from wealthy donors, carefree and wasteful spending and, more generally, from the perception that there is just 'too much money' in politics. In this article we argue that knowledge of and attitudes to party finance matter, not least because advocates of reform have cited public opinion as evidence for reform. However, because attitudes to party finance are part of a broader attitudinal structure, opinion-led reforms are unlikely to succeed in increasing public confidence. Using data generated from YouGov's online panel (N=2,008), we demonstrate that the public know little of the key provisions regulating party finance and attitudes to party finance can be explained along two underlying dimensions - Anti-Party Finance and Reformers. As such, we consider whether parties and politicians should be freed from the constraints of public opinion in reforming party finance.

  16. Third-party punishers are rewarded, but third-party helpers even more so.

    Science.gov (United States)

    Raihani, Nichola J; Bshary, Redouan

    2015-04-01

    Punishers can benefit from a tough reputation, where future partners cooperate because they fear repercussions. Alternatively, punishers might receive help from bystanders if their act is perceived as just and other-regarding. Third-party punishment of selfish individuals arguably fits these conditions, but it is not known whether third-party punishers are rewarded for their investments. Here, we show that third-party punishers are indeed rewarded by uninvolved bystanders. Third parties were presented with the outcome of a dictator game in which the dictator was either selfish or fair and were allocated to one of three treatments in which they could choose to do nothing or (1) punish the dictator, (2) help the receiver, or (3) choose between punishment and helping, respectively. A fourth player (bystander) then sees the third-party's decision and could choose to reward the third party or not. Third parties that punished selfish dictators were more likely to be rewarded by bystanders than third parties that took no action in response to a selfish dictator. However, helpful third parties were rewarded even more than third-party punishers. These results suggest that punishment could in principle evolve via indirect reciprocity, but also provide insights into why individuals typically prefer to invest in positive actions. © 2015 The Author(s).

  17. Social and situational characteristics associated with adolescents' drinking at party and non-party events.

    2017-12-05

    We investigated social and situational characteristics associated with adolescents' drinking at party and non-party events and whether these associations vary by party location (homes versus other locations). Ecological momentary assessment data were obtained over two weekends from 149 adolescents in California (46% female, M age=16.4years), using smartphone surveys administered early and late in the evening and the following morning. We assessed whether, where, and with whom adolescents drank alcohol. Social contexts with more people (RRR=1.05, p≤0.005) and with mixed gender composition (RRR=3.15, p≤0.05) were positively associated with increased risks of alcohol use at parties, but not at non-party events. Conversely, social contexts with friends were positively associated with alcohol use at non-party events (RRR=4.32, p≤0.005), but not at parties. Perceived access to alcohol was associated with increased risks for alcohol use at both party and non-party events, but the association was stronger for alcohol use at parties than non-parties (RRR=1.85, pparties not in homes (RRR=11.29, p≤0.05), and perceptions of getting caught by parents or police were negatively associated with non-party alcohol use in homes (RRR=0.57, p≤0.005). This study identified social-ecological contexts of underage drinking parties, which are high risk settings for heavier drinking and other alcohol-related problems. Findings can inform context-based interventions to target these high-risk settings, whether at homes or other locations. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Spark plasma sintering and spark plasma joining of refractory ceramics

    Science.gov (United States)

    Hoefer, Jeffrey Andrew

    Consolidation of refractory ceramics such as boron carbide (B4C) and silicon carbide (SiC) by conventional sintering techniques (pressure-less sintering, hot pressing, hot isostatic pressing etc.) can prove challenging due to the high temperatures required for sintering. Typically sintering additives are used in order to decrease sintering temperature, but at the sacrifice of purity. Typically B4C requires sintering temperatures above 2000°C without the use of additives, while SiC is generally considered not sinterable without additives, and requires temperatures above 2000°C even with additives. Spark Plasma Sintering (SPS) has emerged as a technology that can reduce the sintering temperature considerably compared to more conventional techniques. The simultaneous application of pressure, heat, and current can reduce sintering temperatures without the use of sintering aids to 1600°C and 2000°C for boron carbide and silicon carbide respectively. One shortcoming of SPS, however, is the difficulty in producing complex shapes. Therefore, for carbide materials such as B4C and SiC, which are difficult to machine, the ability to produce complex shapes is worthy of investigation. One means of creating complex shapes is by joining simple shapes. Joining of monolithic ceramics, in particular SiC, has been achieved, however in all cases an intermediate joining material is used (Ti foil, Silica Powder etc.). Joining of materials using SPS, or as it is called, Spark Plasma Joining, can eliminate the need for an intermediate joining material, producing a high purity and high strength joint. This study investigates SPS of 3 different B4C Powders, as well as SPS joining of simple shape monolithic SiC. Sintering parameters such as temperature, pressure, time, and heating rate are all considered. Influence of sintering parameters on density, grain size, mechanical strength, and joint quality is investigated in detail.

    Full Text Available Today’s political sociologists are once again interested in the study of the crisis of mass-based parties, anti-politics and anti-parliamentarism, crisis in the authority of the political class, prevailing corporate interests within republican institutions, and populism. Political sociology however, takes the party, as a construct of political sociology alone, without consideration upon its militancy and action, as the party, which objectifies the foundation of a State, and as a result the party becomes, simply an historical category. We approach the problem of the modern state from many angles; analysing the nature of a political party as such; the ideological dangers of determinism and spontaneism which a party necessarily must struggle with; the type of non-administrative internal regime which is necessary for a party to be effective and so on. The problem we seek to elaborate is the specific character of the collective action that makes possible the passage from a sectored, corporate and subordinate role of purely negative opposition, to a leading role of conscious action towards not merely a partial adjustment within the system, but posing the issue of the State in its entirety. In developing this theme – as a study of the real relations between the political party, the classes and the State – a two-fold consideration is devoted to the study of Machiavelli and Marx: first from the angle of the real relations between the two, as thinkers of revolutionary politics, of action; and secondly from a perspective which would derive from the Marxist doctrines an articulated system of contemporary politics, as found in The Prince.

  7. Movements in Parties: OccupyPD

    Full Text Available When the United States activists called for people to Occupy#everywhere, it is unlikely they were thinking of the headquarters of the Italian centre-left party. Parties and movements are often considered to be worlds apart. In reality, parties have been relevant players in movement politics, and movements have influenced parties, often through the double militancy of many of their members. OccupyPD testifies to a continuous fluidity at the movement-party border, but also to a blockage in the party’s interactions with society that started long before the economic crisis but drastically accelerated with it. In this paper we present the OccupyPD Movement as a case of interaction between party politics and social movement politics, and in particular between the base membership of a centre-left party and the broader anti-austerity movement that diffused from the US to Europe adopting similar forms of actions and claims. Second, by locating it within the context of the economic and democratic crisis that erupted in 2007, we understand its emergence as a reaction towards politics in times of crisis of responsibility, by which we mean a drastic drop in the capacity of the government to respond to citizens’ requests. To fulfil this double aim, we bridge social movement studies with research on party change, institutional trust and democratic theory, looking at some political effects of the economic crisis in terms of a specific form of legitimacy crisis, as well as citizens’ responses to it, with a particular focus on the political meaning of recent anti-austerity protests. In this analysis, we refer to both quantitative and qualitative data from secondary liter-ature and original in-depth interviews carried out with a sample of OccupyPD activists.

    This paper aims at analyzing school parties from interaction spaces and principals’ narratives in six schools in the state of Jalisco. A party is a ritual where participants share symbols related to imaginary –hence the importance of conducting an analysis for understanding institutions as a symbolic framework. A core argument is that established actors are configured from symbolic practices in the institutional space (schools). The repetition of these practices awash with symbolism leads to ...

    2016-01-01

    Full Text Available The paper presents an overview of results for wing-body interference, obtained by the author for varied wing-body combinations. The lift-curve slopes of the wing-body combinations are considered. In this paper a discrete vortices method (DVM and 2D potential model for cross-flow around fuselage are used. The circular and elliptical cross-sections of the fuselage and flat wings of various forms are considered. Calculations showed that the value of the lift-curve slopes of the wing-body combinations may exceed the same value for an isolated wing. This result confirms an experimental data obtained by other authors earlier. Within a framework of the used mathematical models the investigations to optimize the wing-body combination were carried. The present results of the optimization problem for the wing-body combination allowed to select the optimal geometric characteristics for configuration to maximize the values of the lift-curve slopes of the wing-body combination. It was revealed that maximums of the lift-curve slopes for the optimal mid-wing configuration with elliptical cross-section body had a sufficiently large relative width of the body (more than 30% of the span wing.

  12. Optimization of Conical Wings in Hypersonic Flow

    Triantafillou, S. A.; Schwendeman, D. W.; Cole, J. D.

    A method of calculation is presented to determine conical wing shapes that minimize the coefficient of (wave) drag, CD, for a fixed coefficient of lift, CL, in steady, hypersonic flow. An optimization problem is considered for the compressive flow underneath wings at a small angle of attack δ and at a high free-stream Mach number M∞ so that hypersonic small-disturbance (HSD) theory applies. A figure of merit, F=CD/CL3/2, is computed for each wing using a finite volume discretization of the HSD equations. A set of design variables that determine the shape of the wing is defined and adjusted iteratively to find a shape that minimizes F for a given value of the hypersonic similarity parameter, H= (M∞δ)-2, and planform area. Wings with both attached and detached bow shocks are considered. Optimal wings are found for flat delta wings and for a family of caret wings. In the flat-wing case, the optima have detached bow shocks while in the caret-wing case, the optimum has an attached bow shock. An improved drag-to-lift performance is found using the optimization procedure for curved wing shapes. Several optimal designs are found, all with attached bow shocks. Numerical experiments are performed and suggest that these optima are unique.

  13. Periodic and Chaotic Flapping of Insectile Wings

    CERN Document Server

    Huang, Yangyang

    2015-01-01

    Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of energy in the insect flight system. Here, we explore the intrinsic self-oscillatory behavior of an insectile wing model, consisting of two rigid wings connected at their base by an elastic torsional spring. We study the wings behavior as a function of the total energy and spring stiffness. Three types of behavior are identified: end-over-end rotation, chaotic motion, and periodic flapping. Interestingly, the region of periodic flapping decreases as energy increases but is favored as stiffness increases. These findings are consistent with the fact that insect wings and flight muscles are stiff. They further imply that, by adjusting their muscle stiffness to the desired energy level, insects can maintain periodic flapping mechanically for a range of operating condit...

  14. Topology of Vortex-Wing Interaction

    McKenna, Chris; Rockwell, Donald

    2016-11-01

    Aircraft flying together in an echelon or V formation experience aerodynamic advantages. Impingement of the tip vortex from the leader (upstream) wing on the follower wing can yield an increase of lift to drag ratio. This enhancement is known to depend on the location of vortex impingement on the follower wing. Particle image velocimetry is employed to determine streamline topology in successive crossflow planes, which characterize the streamwise evolution of the vortex structure along the chord of the follower wing and into its wake. Different modes of vortex-follower wing interaction are created by varying both the spanwise and vertical locations of the leader wing. These modes are defined by differences in the number and locations of critical points of the flow topology, and involve bifurcation, attenuation, and mutual induction. The bifurcation and attenuation modes decrease the strength of the tip vortex from the follower wing. In contrast, the mutual induction mode increases the strength of the follower tip vortex. AFOSR.

  15. Modeling interactions between political parties and electors

    2017-09-01

    In this paper we extend some recent results on an operatorial approach to the description of alliances between political parties interacting among themselves and with a basin of electors. In particular, we propose and compare three different models, deducing the dynamics of their related decision functions, i.e. the attitude of each party to form or not an alliance. In the first model the interactions between each party and their electors are considered. We show that these interactions drive the decision functions toward certain asymptotic values depending on the electors only: this is the perfect party, which behaves following the electors' suggestions. The second model is an extension of the first one in which we include a rule which modifies the status of the electors, and of the decision functions as a consequence, at some specific time step. In the third model we neglect the interactions with the electors while we consider cubic and quartic interactions between the parties and we show that we get (slightly oscillating) asymptotic values for the decision functions, close to their initial values. This is the real party, which does not listen to the electors. Several explicit situations are considered in details and numerical results are also shown.

    2014-01-01

    This study examines the effect of situational variables on whether third parties intervene in conflicts in barroom settings, and whether they are aggressive or not when they intervene. Based on research on bystander intervention in emergencies, we hypothesized that third parties would be most likely to become involved in incidents with features that convey greater danger of serious harm. The situational variables indicative of danger were severity of aggression, whether the aggression was one-sided or mutual, gender, and level of intoxication of the initial participants in the conflict. Analyses consist of cross-tabulations and three-level Hierarchical Logistic Models (with bar, evening, and incidents as levels) for 860 incidents of verbal and physical aggression from 503 nights of observation in 87 large bars and clubs in Toronto, Canada. Third party involvement was more likely during incidents in which: (1) the aggression was more severe; (2) the aggression was mutual (vs. one-sided) aggression; (3) only males (vs. mixed gender) were involved; and (4) participants were more intoxicated. These incident characteristics were stronger predictors of nonaggressive third party involvement than aggressive third party involvement. The findings suggest that third parties are indeed responding to the perceived danger of serious harm. Improving our knowledge about this aspect of aggressive incidents is valuable for developing prevention and intervention approaches designed to reduce aggression in bars and other locations.

  18. Shape and Structural Optimization of Flapping Wings

    Science.gov (United States)

    Stewart, Eric Colby

    This dissertation presents shape and structural optimization studies on flapping wings for micro air vehicles. The design space of the optimization includes the wing planform and the structural properties that are relevant to the wing model being analyzed. The planform design is parameterized using a novel technique called modified Zimmerman, which extends the concept of Zimmerman planforms to include four ellipses rather than two. Three wing types are considered: rigid, plate-like deformable, and membrane. The rigid wing requires no structural design variables. The structural design variables for the plate-like wing are the thickness distribution polynomial coefficients. The structural variables for the membrane wing control the in-plane distributed forces which modulate the structural deformation of the wing. The rigid wing optimization is performed using the modified Zimmerman method to describe the wing. A quasi-steady aerodynamics model is used to calculate the thrust and input power required during the flapping cycle. An assumed inflow model is derived based on lifting-line theory and is used to better approximate the effects of the induced drag on the wing. A multi-objective optimization approach is used since more than one aspect is considered in flapping wing design. The the epsilon-constraint approach is used to calculate the Pareto optimal solutions that maximize the cycle-average thrust while minimizing the peak input power and the wing mass. An aeroelastic model is derived to calculate the aerodynamic performance and the structural response of the deformable wings. A linearized unsteady vortex lattice method is tightly coupled to a linear finite element model. The model is cost effective and the steady-state solution is solved by inverting a matrix. The aeroelastic model is used to maximize the thrust produced over one flapping cycle while minimizing the input power.

This thesis examines the Labour Party in opposition since 1979, using a theoretical framework informed by Anthony Giddens' structuration theory. Based on a dialectical notion of the structure and agency linkage, a two-tiered framework is constructed which at on...

  20. New Joining Technology for Optimized Metal/Composite Assemblies

    Directory of Open Access Journals (Sweden)

    Holger Seidlitz

    2014-01-01

    Full Text Available The development of a new joining technology, which is used to manufacture high strength hybrid constructions with thermoplastic composites (FRP and metals, is introduced. Similar to natural regulation effects at trees, fibers around the FRP joint become aligned along the lines of force and will not be destroyed by the joining process. This is achieved by the local utilization of the specific plastic flow properties of the FRT and metal component. Compared with usual joining methods—such as flow drill screws, blind and self-piercing rivets—noticeably higher tensile properties can be realized through the novel process management. The load-bearing capability increasing effect could be proved on hybrid joints with hot-dip galvanized steel HX420LAD and orthotropic glass—as well as carbon—fiber reinforced plastics. The results, which were determined in tensile-shear and cross-shear tests according to DIN EN ISO 14273 and DIN EN ISO 14272, are compared with holding loads of established joining techniques with similar joining point diameter and material combinations.

  1. Experimental optimization of wing shape for a hummingbird-like flapping wing micro air vehicle.

    2017-03-06

    Flapping wing micro air vehicles (MAVs) take inspiration from natural fliers, such as insects and hummingbirds. Existing designs manage to mimic the wing motion of natural fliers to a certain extent; nevertheless, differences will always exist due to completely different building blocks of biological and man-made systems. The same holds true for the design of the wings themselves, as biological and engineering materials differ significantly. This paper presents results of experimental optimization of wing shape of a flexible wing for a hummingbird-sized flapping wing MAV. During the experiments we varied the wing 'slackness' (defined by a camber angle), the wing shape (determined by the aspect and taper ratios) and the surface area. Apart from the generated lift, we also evaluated the overall power efficiency of the flapping wing MAV achieved with the various wing design. The results indicate that especially the camber angle and aspect ratio have a critical impact on the force production and efficiency. The best performance was obtained with a wing of trapezoidal shape with a straight leading edge and an aspect ratio of 9.3, both parameters being very similar to a typical hummingbird wing. Finally, the wing performance was demonstrated by a lift-off of a 17.2 g flapping wing robot.

  3. Similitude relations for buffet and wing rock on delta wings

    1997-08-01

    Vortex flow phenomena at high angles of incidence are of great interest to the designers of advanced combat aircraft. The steady phenomena (such as steady lift and pitching moments) are understood fairly well, whereas the unsteady phenomena are still uncertain. This paper addresses two important unsteady phenomena on delta wings. With regard to the frequency parameter of the quasi-periodic excitation caused by vortex bursting, a new correlation is established covering a range of sweep back from 60 to 75°. With regard to the much lower frequency parameter of limit-cycle rigid-body wing-rock, a new experiment shows conclusively that although the motion is non-linear, the frequency parameter can be predicted by quasi-steady theory. As a consequence, for a given sweep angle, the frequency parameter is inversely proportional to the square root of the inertia in roll. This is an important observation when attempting to extrapolate from model tests in wind tunnels to predict the wing-rock characteristics of aircraft.

  4. Identifying Islamist Parties Using Gunther and Diamond’s Typology

    Directory of Open Access Journals (Sweden)

    Raja M. Ali Saleem

    2014-08-01

    Full Text Available Recent democratization in the Muslim-majority countries (MMCs has led to a surge in interest in the Islamist (or Islamic parties. Research on these parties has, however, been plagued by the lack of agreement on identifying these parties. Analysis of various ways used to identify/define Islamist parties shows shortcomings. This article tries to resolve the conundrum by identifying these parties within a comparative framework, that is, Gunther and Diamond party typology. Two major types of Islamist parties are identified and placed within the Gunther and Diamond typology. This solution has two advantages. First, discussions on Islamist parties can now become more grounded, restricting analysts from labeling any conservative party in the MMCs as Islamist. Second, Islamist parties can be part of the general discussion on political parties in the literature, and inclination to regard them as singular or exceptional, because of their link with Islam, is discouraged.

  5. Advances in Solid State Joining of High Temperature Alloys

    Ding, Jeff; Schneider, Judy

    2011-01-01

    Many of the metals used in the oil and gas industry are difficult to fusion weld including Titanium and its alloys. Solid state joining processes are being pursued as an alternative process to produce robust structures more amenable to high pressure applications. Various solid state joining processes include friction stir welding (FSW) and a patented modification termed thermal stir welding (TSW). The configuration of TSWing utilizes an induction coil to preheat the material minimizing the burden on the weld tool extending its life. This provides the ability to precisely select and control the temperature to avoid detrimental changes to the microstructure. The work presented in this presentation investigates the feasibility of joining various titanium alloys using the solid state welding processes of FSW and TSW. Process descriptions and attributes of each weld process will be presented. Weld process set ]up and welding techniques will be discussed leading to the challenges experienced. Mechanical property data will also be presented.

    2014-12-01

    Full Text Available This paper is about the importance of modern left-wing European politics in the process of construction of European Union. In our paper, we have tried to discern the main elements of the contemporary European left-wing, focusing on that which may currently be considered the essence of the offer of the left-wing political parties: the European societal model. The European societal model lies at the heart of most European, but also Transatlantic, intellectual debates. It is an ongoing process, which is still quite far from the final agreement stage. The European Socialists (Social- Democrats claim the avant-garde of the construction and modernization of the European societal model. This model constitutes an important political and even ideological bet – in a global context – for the European left-wing. Political, as the left-wing desires to prove the superiority of their pan- European views in relation to the Neo-liberals and the non-Conservatives who either oppose integration or promote incoherent projects. Ideological in a global context, as the European left-wing desires to prove the superiority of the European societal model/European model of life over the North American one, symbol of the neo-liberal mundialization.

    2011-04-01

    Full Text Available The Romanian government has announced plans to join the eurozone by 2015. Currently, the leu is not yet part of ERM II but plans to join in 2010-2012. The economic advantages of the monetary union grow with expansion of the Euro zone. There is also a high level of skepticism; the main fear about the Euro is the inflation –that is considerable promoted by the Euro currency’s exchange rate in comparison with 2002; another restraint is due to member states inability to establish their own interest rates. The IMF arose the option of joining the Euro zone criteria relaxing. A one-sided Euro’s joining was suggested by International Monetary Fund on March-April 2009, in a confidential report mentioned by The Financial Times as the emergent states in Central and Eastern Europe to be able to pass to the unique currency, but not being represented in the Central European Bank Board. By its side, CEB considers that emergent states of the European Union must not pass to the unique currency unilaterally, because such a fact could under-mine the trust in Euro currency worldwide. This option would hardly deepen the macroeconomic controversies inside the Euro zone and would contradict the previous conditions already imposed. An acceptable solution could be the fastening of emergent countries joining the Exchange Rate Mechanism 2, after they are aware of risks arisen by such a step. The European Commission endorses in the Convergence Report on 2010 that Romania doesn’t meet any criteria needed by passing to the unique European currency, respectively: prices stability; budget position of the government; stability of exchange rate; interest convergence on long run and there are also law impediments. Our paper discusses arguments for a faster passing to the Euro currency versus arguments for a late joining the Euro currency in Romania.

    Joining by upset bulging is a mechanical joining method where axial load is applied to a tube to form two revolving bulges, which clamp the parts to be joined and create a force and form fit. It can be used to join tubes with other structures such as sheets, plates, tubes or profiles of the same or different materials. Other processes such as welding are often limited in joining multi-material assemblies or high-strength materials. With joining by upset bulging at room temperature, the main drawback is the possible initiation of damage (cracks) in the inner buckling zone because of high local stresses and strains. In this paper, a method to avoid the formation of cracks is introduced. Before forming the bulge the tube is locally heated by an induction coil. For the construction steel (E235+N) a maximum temperature of 700 °C was used to avoid phase transformation. For the numerical study of the process the mechanical properties of the tube material were examined at different temperatures and strain rates to determine its flow curves. A parametrical FE model was developed to simulate the bulging process with local heating. Experiments with local heating were executed and metallographic studies of the bulging area were conducted. While specimens heated to 500 °C showed small cracks left, damage-free flanges could be created at 600 and 700 °C. Static testing of damage-free bulges showed improvements in tensile strength and torsion strength compared to bulges formed at room-temperature, while bending and compression behavior remained nearly unchanged. In cyclic testing the locally heated specimens underwent about 3.7 times as many cycles before failure as the specimens formed at room temperature.

    Full Text Available This article based on the study of the theory and practice of party­building in Ukraine examines the role of party leader in the political process and the establishment of parties, implementation of the political power, the development of political consciousness and the formation of modern political elite of our country. It is alleged that party leader – a reputable, recognized in its political environment, the person chosen to lead the party and the ability of citizens to consolidate around a common goal, most effectively represent the interests of a particular social group. It is stated that the defining feature of the phenomenon of party leadership is that under conditions of constant political development and irreversibility of democratic transformations in Ukraine part of leaders of political parties in fact is a powerful talent pool for senior government officials, local government agencies and other administrative institutions. The process of creating games as an integral part of the political process is characterized by a certain way, the mechanism of action of consciousness and culture in the public sphere, which deals with political parties. Regularities component of modern political elite of the party elite acts ­ governing the range of persons in the political party headed by its leader that are directly involved in strategic decision­making, policy formulation of this power, as well as its participation in the political process. We study the classification model of national political parties and the institutions of the party leadership. It is proposed to assess the level of correlation of the party leaders and the general dynamics of the civil society in Ukraine. It is stated that at this time a fundamental change in Ukrainian Party elite has not happened yet. However, there is a long evolution of the institute of the party leadership – a rather difficult process of internal and external, objective and subjective, economic

    1992-11-01

    The development of joining techniques for fusion reactor divertors has been undertaken at ENEA (Italian Agency for Energy, New Technologies and the Environment) IFEC Saluggia. Joints were made by the diffusion bonding technique between graphite composite material with DS copper and with molybdenum TZM alloy, respectively. The inter-layers, when necessary, were obtained by metallization with an electronic gun. The same technique is employed in joining Be/SS, DS copper/Be, TZM/Be and graphite/Be for the first wall or plasma facing components of fusion reactors. In this case, a suitable inter-layer material can avoid the problems occuring with the more traditional brazing processes.

    Steady-state creep and joining of alumina/zirconia composites containing alumina volume fractions of 20, 60, and 85% have been investigated between 1,250 and 1,350 C. Superplasticity of these compounds is controlled by grain-boundary sliding and the creep rate is a function of alumina volume fraction, not grain size. Using the principles of superplasticity, pieces of the composite have been joined by applying the stress required to achieve 5 to 10% strain to form a strong interface at temperatures as low as 1,200 C.

    Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast, wings flapping at high angles of attack generate stable leading edge vorticity, which persists throughout the duration of the stroke and enhances mean aerodynamic forces. Here, we show that aerodynamic forces can be controlled by altering the trailing edge flexibility of a flapping wing. We used a dynamically scaled mechanical model of flapping flight (Re approximately 2000) to measure the aerodynamic forces on flapping wings of variable flexural stiffness (EI). For low to medium angles of attack, as flexibility of the wing increases, its ability to generate aerodynamic forces decreases monotonically but its lift-to-drag ratios remain approximately constant. The instantaneous force traces reveal no major differences in the underlying modes of force generation for flexible and rigid wings, but the magnitude of force, the angle of net force vector and centre of pressure all vary systematically with wing flexibility. Even a rudimentary framework of wing veins is sufficient to restore the ability of flexible wings to generate forces at near-rigid values. Thus, the magnitude of force generation can be controlled by modulating the trailing edge flexibility and thereby controlling the magnitude of the leading edge vorticity. To characterize this, we have generated a detailed database of aerodynamic forces as a function of several variables including material properties, kinematics, aerodynamic forces and centre of pressure, which can also be used to help validate computational models of aeroelastic flapping wings. These experiments will also be useful for wing design for small

  16. Centurion in Flight with Internal Wing Structure Visible

    1998-01-01

    The lightweight wing structure and covering of the Centurion remotely piloted flying wing can be clearly seen in this photo of the plane during one of its initial low-altitude, battery-powered test flights in late 1998 at NASA's Dryden Flight Research Center, Edwards, California. Centurion was a unique remotely piloted, solar-powered airplane developed under NASA's Environmental Research Aircraft and Sensor (ERAST) Program at the Dryden Flight Research Center, Edwards, California. Dryden joined with AeroVironment, Inc., Monrovia, California, under an ERAST Joint Sponsored Research Agreement, to design, develop, manufacture, and conduct flight development tests for the Centurion. The airplane was believed to be the first aircraft designed to achieve sustained horizontal flight at altitudes of 90,000 to 100,000 feet. Achieving this capability would meet the ERAST goal of developing an ultrahigh-altitude airplane that could meet the needs of the science community to perform upper-atmosphere environmental data missions. Much of the technology leading to the Centurion was developed during the Pathfinder and Pathfinder-Plus projects. However, in the course of its development, the Centurion became a prototype technology demonstration aircraft designed to validate the technology for the Helios, a planned future high-altitude, solar-powered aircraft that could fly for weeks or months at a time on science or telecommunications missions. Centurion had 206-foot-long wings and used batteries to supply power to the craft's 14 electric motors and electronic systems. Centurion first flew at Dryden Nov. 10, 1998, and followed up with a second test flight Nov. 19. On its third and final flight on Dec. 3, the craft was aloft for 31 minutes and reached an altitude of about 400 feet. All three flights were conducted over a section of Rogers Dry Lake adjacent to Dryden. For its third flight, the Centurion carried a simulated payload of more than 600 pounds--almost half the lightweight

  17. Effects of wing locations on wing rock induced by forebody vortices

    Directory of Open Access Journals (Sweden)

    Ma Baofeng

    2016-10-01

    Full Text Available Previous studies have shown that asymmetric vortex wakes over slender bodies exhibit a multi-vortex structure with an alternate arrangement along a body axis at high angle of attack. In this investigation, the effects of wing locations along a body axis on wing rock induced by forebody vortices was studied experimentally at a subcritical Reynolds number based on a body diameter. An artificial perturbation was added onto the nose tip to fix the orientations of forebody vortices. Particle image velocimetry was used to identify flow patterns of forebody vortices in static situations, and time histories of wing rock were obtained using a free-to-roll rig. The results show that the wing locations can affect significantly the motion patterns of wing rock owing to the variation of multi-vortex patterns of forebody vortices. As the wing locations make the forebody vortices a two-vortex pattern, the wing body exhibits regularly divergence and fixed-point motion with azimuthal variations of the tip perturbation. If a three-vortex pattern exists over the wing, however, the wing-rock patterns depend on the impact of the highest vortex and newborn vortex. As the three vortices together influence the wing flow, wing-rock patterns exhibit regularly fixed-points and limit-cycled oscillations. With the wing moving backwards, the newborn vortex becomes stronger, and wing-rock patterns become fixed-points, chaotic oscillations, and limit-cycled oscillations. With further backward movement of wings, the vortices are far away from the upper surface of wings, and the motions exhibit divergence, limit-cycled oscillations and fixed-points. For the rearmost location of the wing, the wing body exhibits stochastic oscillations and fixed-points.

  18. Flexible Wing Model for Structural Sizing and Multidisciplinary Design Optimization of a Strut-Braced Wing

    Gern, Frank H.; Naghshineh, Amir H.; Sulaeman, Erwin; Kapania, Rakesh K.; Haftka, Raphael T.

    2000-01-01

    This paper describes a structural and aeroelastic model for wing sizing and weight calculation of a strut-braced wing. The wing weight is calculated using a newly developed structural weight analysis module considering the special nature of strut-braced wings. A specially developed aeroelastic model enables one to consider wing flexibility and spanload redistribution during in-flight maneuvers. The structural model uses a hexagonal wing-box featuring skin panels, stringers, and spar caps, whereas the aerodynamics part employs a linearized transonic vortex lattice method. Thus, the wing weight may be calculated from the rigid or flexible wing spanload. The calculations reveal the significant influence of the strut on the bending material weight of the wing. The use of a strut enables one to design a wing with thin airfoils without weight penalty. The strut also influences wing spanload and deformations. Weight savings are not only possible by calculation and iterative resizing of the wing structure according to the actual design loads. Moreover, as an advantage over the cantilever wing, employment of the strut twist moment for further load alleviation leads to increased savings in structural weight.

  19. Role of wing morphing in thrust generation

    Directory of Open Access Journals (Sweden)

    Mehdi Ghommem

    2014-01-01

    Full Text Available In this paper, we investigate the role of morphing on flight dynamics of two birds by simulating the flow over rigid and morphing wings that have the characteristics of two different birds, namely the Giant Petrel and Dove Prion. The simulation of a flapping rigid wing shows that the root of the wing should be placed at a specific angle of attack in order to generate enough lift to balance the weight of the bird. However, in this case the generated thrust is either very small, or even negative, depending on the wing shape. Further, results show that morphing of the wing enables a significant increase in the thrust and propulsive efficiency. This indicates that the birds actually utilize some sort of active wing twisting and bending to produce enough thrust. This study should facilitate better guidance for the design of flapping air vehicles.

  20. Constraints on the wing morphology of pterosaurs.

    Science.gov (United States)

    Palmer, Colin; Dyke, Gareth

    2012-03-22

    Animals that fly must be able to do so over a huge range of aerodynamic conditions, determined by weather, wind speed and the nature of their environment. No single parameter can be used to determine-let alone measure-optimum flight performance as it relates to wing shape. Reconstructing the wings of the extinct pterosaurs has therefore proved especially problematic: these Mesozoic flying reptiles had a soft-tissue membranous flight surface that is rarely preserved in the fossil record. Here, we review basic mechanical and aerodynamic constraints that influenced the wing shape of pterosaurs, and, building on this, present a series of theoretical modelling results. These results allow us to predict the most likely wing shapes that could have been employed by these ancient reptiles, and further show that a combination of anterior sweep and a reflexed proximal wing section provides an aerodynamically balanced and efficient theoretical pterosaur wing shape, with clear benefits for their flight stability.

  2. Parties, rituals and symbolisms in schools

    Directory of Open Access Journals (Sweden)

    Ana Cecilia Valencia Aguirre

    2015-07-01

    Full Text Available This paper aims at analyzing school parties from interaction spaces and principals’ narratives in six schools in the state of Jalisco. A party is a ritual where participants share symbols related to imaginary –hence the importance of conducting an analysis for understanding institutions as a symbolic framework. A core argument is that established actors are configured from symbolic practices in the institutional space (schools. The repetition of these practices awash with symbolism leads to daily rituals or micro rituals that are ratified in institutions. Methodologically, interviews and non-participant observation in school interaction spaces were used. Based on the findings, it may be stated that the nuclear family, rooted in the Christian image in which authority is a central point, becomes a fundamental factor in shaping institutional life as well as the imaginary linked to school parties.

  15. Improved Joining of Metal Components to Composite Structures

    Semmes, Edmund

    2009-01-01

    Systems requirements for complex spacecraft drive design requirements that lead to structures, components, and/or enclosures of a multi-material and multifunctional design. The varying physical properties of aluminum, tungsten, Invar, or other high-grade aerospace metals when utilized in conjunction with lightweight composites multiply system level solutions. These multi-material designs are largely dependent upon effective joining techAn improved method of joining metal components to matrix/fiber composite material structures has been invented. The method is particularly applicable to equipping such thin-wall polymer-matrix composite (PMC) structures as tanks with flanges, ceramic matrix composite (CMC) liners for high heat engine nozzles, and other metallic-to-composite attachments. The method is oriented toward new architectures and distributing mechanical loads as widely as possible in the vicinities of attachment locations to prevent excessive concentrations of stresses that could give rise to delaminations, debonds, leaks, and other failures. The method in its most basic form can be summarized as follows: A metal component is to be joined to a designated attachment area on a composite-material structure. In preparation for joining, the metal component is fabricated to include multiple studs projecting from the aforementioned face. Also in preparation for joining, holes just wide enough to accept the studs are molded into, drilled, or otherwise formed in the corresponding locations in the designated attachment area of the uncured ("wet') composite structure. The metal component is brought together with the uncured composite structure so that the studs become firmly seated in the holes, thereby causing the composite material to become intertwined with the metal component in the joining area. Alternately, it is proposed to utilize other mechanical attachment schemes whereby the uncured composite and metallic parts are joined with "z-direction" fasteners. The

    Political parties are indispensable for the functioning of liberal democracies. However, the political parties of many transitional and developing countries are not functioning well. This fact has led to increasing donor support to political parties. However, due to the political sensitivity of the issue, donors are not supporting political parties directly. There are two indirect methods for party support. One is support for broadening democracy, assuming that this will also strengthen polit...

  19. Veins improve fracture toughness of insect wings.

    Directory of Open Access Journals (Sweden)

    Jan-Henning Dirks

    Full Text Available During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect's flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material's resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04±0.25 MPa√m. However, the cross veins increase the wing's toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 µm. This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically 'optimal' solution with high toughness and low weight. The vein pattern found in insect wings thus might inspire the design of more durable and lightweight artificial 'venous' wings for micro-air-vehicles. Using the vein spacing as indicator, our approach might also provide a basis to estimate the wing properties of endangered or extinct insect species.

  20. The function of resilin in honeybee wings.

    2015-07-01

    The present work aimed to reveal morphological characteristics of worker honeybee (Apis mellifera) wings and demonstrate the function of resilin on camber changes during flapping flight. Detailed morphological investigation of the wings showed that different surface characteristics appear on the dorsal and ventral side of the honeybee wings and the linking structure connecting the forewing and hindwing plays an indispensable role in honeybee flapping flight. Resilin stripes were found on both the dorsal and ventral side of the wings, and resilin patches mostly existed on the ventral side. On the basis of resilin distribution, five flexion lines and three cambered types around the lines of passive deformation of the coupled-wing profile were obtained, which defined the deformation mechanism of the wing along the chord, i.e. concave, flat plate and convex. From a movie obtained using high-speed photography from three orthogonal views of free flight in honeybees, periodic changes of the coupled-wing profile were acquired and further demonstrated that the deformation mechanism is a fundamental property for variable deformed shapes of the wing profile during flapping flight, and, in particular, the flat wing profile achieves a nice transition between downstrokes and upstrokes. © 2015.

    Different from studies of butterfly wings through additive modification, this work for the first time studies the property change of butterfly wings through subtractive modification using oxygen plasma etching. The controlled modification of butterfly wings through such subtractive process results in gradual change of the optical properties, and helps the further understanding of structural optimization through natural evolution. The brilliant color of Morpho butterfly wings is originated from the hierarchical nanostructure on the wing scales. Such nanoarchitecture has attracted a lot of research effort, including the study of its optical properties, its potential use in sensing and infrared imaging, and also the use of such structure as template for the fabrication of high-performance photocatalytic materials. The controlled subtractive processes provide a new path to modify such nanoarchitecture and its optical property. Distinct from previous studies on the optical property of the Morpho wing structure, this study provides additional experimental evidence for the origination of the optical property of the natural butterfly wing scales. The study also offers a facile approach to generate new 3D nanostructures using butterfly wings as the templates and may lead to simpler structure models for large-scale man-made structures than those offered by original butterfly wings. © 2015 WILEY-VCH Verlag GmbH & Co.

    The Tea Party, which gained prominence in the USA in 2009, advocates limited government and low taxes. Tea Party organisations, particularly Americans for Prosperity and FreedomWorks, oppose smoke-free laws and tobacco taxes. We used the Legacy Tobacco Documents Library, the Wayback Machine, Google, LexisNexis, the Center for Media and Democracy and the Center for Responsive Politics (opensecrets.org) to examine the tobacco companies' connections to the Tea Party. Starting in the 1980s, tobacco companies worked to create the appearance of broad opposition to tobacco control policies by attempting to create a grassroots smokers' rights movement. Simultaneously, they funded and worked through third-party groups, such as Citizens for a Sound Economy, the predecessor of AFP and FreedomWorks, to accomplish their economic and political agenda. There has been continuity of some key players, strategies and messages from these groups to Tea Party organisations. As of 2012, the Tea Party was beginning to spread internationally. Rather than being a purely grassroots movement that spontaneously developed in 2009, the Tea Party has developed over time, in part through decades of work by the tobacco industry and other corporate interests. It is important for tobacco control advocates in the USA and internationally, to anticipate and counter Tea Party opposition to tobacco control policies and ensure that policymakers, the media and the public understand the longstanding connection between the tobacco industry, the Tea Party and its associated organisations.

    Future quantum information networks will consist of quantum and classical agents, who have the ability to communicate in a variety of ways with trusted and untrusted parties and securely delegate computational tasks to untrusted large-scale quantum computing servers. Multipartite quantum entanglement is a fundamental resource for such a network and, hence, it is imperative to study the possibility of verifying a multipartite entanglement source in a way that is efficient and provides strong guarantees even in the presence of multiple dishonest parties. In this Letter, we show how an agent of a quantum network can perform a distributed verification of a source creating multipartite Greenberger-Horne-Zeilinger (GHZ) states with minimal resources, which is, nevertheless, resistant against any number of dishonest parties. Moreover, we provide a tight tradeoff between the level of security and the distance between the state produced by the source and the ideal GHZ state. Last, by adding the resource of a trusted common random source, we can further provide security guarantees for all honest parties in the quantum network simultaneously.

    Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

  1. Biaxial mechanical characterization of bat wing skin.

    2015-04-21

    The highly flexible and stretchable wing skin of bats, together with the skeletal structure and musculature, enables large changes in wing shape during flight. Such compliance distinguishes bat wings from those of all other flying animals. Although several studies have investigated the aerodynamics and kinematics of bats, few have examined the complex histology and mechanical response of the wing skin. This work presents the first biaxial characterization of the local deformation, mechanical properties, and fiber kinematics of bat wing skin. Analysis of these data has provided insight into the relationships among the structural morphology, mechanical properties, and functionality of wing skin. Large spatial variations in tissue deformation and non-negligible fiber strains in the cross-fiber direction for both chordwise and spanwise fibers indicate fibers should be modeled as two-dimensional elements. The macroscopic constitutive behavior was anisotropic and nonlinear, with very low spanwise and chordwise stiffness (hundreds of kilopascals) in the toe region of the stress-strain curve. The structural arrangement of the fibers and matrix facilitates a low energy mechanism for wing deployment and extension, and we fabricate examples of skins capturing this mechanism. We propose a comprehensive deformation map for the entire loading regime. The results of this work underscore the importance of biaxial field approaches for soft heterogeneous tissue, and provide a foundation for development of bio-inspired skins to probe the effects of the wing skin properties on aerodynamic performance.

  2. Advanced wing design survivability testing and results

    Bruno, J.; Tobias, M.

    1992-01-01

    Composite wings on current operational aircraft are conservatively designed to account for stress/strain concentrations, and to assure specified damage tolerance. The technology that can lead to improved composite wing structures and associated structural efficiency is to increase design ultimate strain levels beyond their current limit of 3500 to 4000 micro-in/in to 6000 micro-in/in without sacrificing structural integrity, durability, damage tolerance, or survivability. Grumman, under the sponsorship of the Naval Air Development Center (NADC), has developed a high-strain composite wing design for a subsonic aircraft wing using novel and innovative design concepts and manufacturing methods, while maintaining a state-of-the-art fiber/resin system. The current advanced wing design effort addressed a tactical subsonic aircraft wing using previously developed, high-strain wing design concepts in conjunction with newer/emerging fiber and polymer matrix composite (PMC) materials to achieve the same goals, while reducing complexity. Two categories of advanced PMC materials were evaluated: toughened thermosets; and engineered thermoplastics. Advanced PMC materials offer the technological opportunity to take maximum advantage of improved material properties, physical characteristics, and tailorability to increase performance and survivability over current composite structure. Damage tolerance and survivability to various threats, in addition to structural integrity and durability, were key technical issues addressed during this study, and evaluated through test. This paper focuses on the live-fire testing, and the results performed to experimentally evaluate the survivability of the advanced wing design.

    The ability to effectively join materials with vastly different melting points like Aluminum-Steel, Polymer composites - metals has been one of the road blocks in realizing multi-material components for light weighting efforts. Friction stir scribe (FSS) technique is a promising method that produces continuous overlap joint between materials with vastly different melting regimes and high temperature flow characteristics. FSS uses an offset cutting tool at the tip of the FSW pin to create an insitu mechanical interlock between material interfaces. With investments from Vehicle Technology office, US DOE and several automotive manufacturers and suppliers PNNL is developing the FSS process and has demonstrated viability of joining several material combinations. Details of welding trails, unique challenges and mitigation strategies in different material combinations will be discussed. Joint characterization including mechanical tests and joint performances will also be presented.

    Full Text Available The semisolid metal joining (SSMJ process or thixojoining process has recently been developed based on the principles of SSM processing, which is a technology that involves the formation of metal alloys between solidus and liquidus temperatures. Thixojoining has many potential benefits, which has encouraged researchers to carry out feasibility studies on various materials that could be utilized in this process and which could transform the production of metal components. This paper reviews the findings in the literature to date in this evolving field, specifically, the experimental details, technology considerations for industrialization, and advantages and disadvantages of the various types of SSMJ methods that have been proposed. It also presents details of the range of materials that have been joined by using the SSMJ process. Furthermore, it highlights the huge potential of this process and future directions for further research.

    As a public health problem, suicidal behavior demands a community-level response, including government action. We aimed to test whether support for suicide prevention in the United States has been independent from political party affiliation (Democrat and Republican). Actions from both political parties have supported suicide prevention efforts. The only differences in support based on party affiliation showed greater support from the Democrat Party in one instance, and the Republican Party in the other. The results were consistent with the hypothesis that degree of support for suicide prevention cannot be predicted solely by political party. © 2017 The American Association of Suicidology.

    Full Text Available Though nationalism has always been strong in Iceland, populist political parties did not emerge as a viable force until after the financial crisis of 2008. On wave of the crisis a completely renewed leadership took over the country’s old agrarian party, the Progressive Party (PP, which was rapidly transformed in a more populist direction. Still the PP is perhaps more firmly nationalist than populist. However, when analyzing communicational changes of the new postcrisis leadership it is unavoidable to categorize the party amongst at least the softer version of European populist parties, perhaps closest to the Norwegian Progress Party.

    Party nationalisation, defined as the homogeneity of party strength across a country, has recently become a major issue in research. Even though territory is a salient political question in the post- communist countries in Europe, party nationalisation in these countries has been neglected...... by the literature so far. This article presents data on party nationalisation for 20 countries over the period 1990–2007. It shows that the nationalisation of party systems in post-communist democracies is closely related to the territorial structure of social divisions, except for cases where the electoral systems...... provide for a high degree of nationalisation, or where super-presidentialism inhibits the creation of strong nationalised parties....

    The possibility of intra-party democracy appearance as a sustainable and well played phenomena can only be based on the formation of political parties as a competitive and dynamic structures that have a high degree of internal relationships and a clear understanding of a common goal that is shared by both the governing parties and the basis of parties and ordinary party members. Distribution of party members in top management, middle functional rank and ordinary members is an obvious consequence of the organizational functioning of any extensive and systematic organization.

    Strathman, Joseph; Watkins, Steve E.; Kaur, Amardeep; Macke, David C.

    2016-04-01

    An instrumented composite wing is described. The wing is designed to meet the load and ruggedness requirements for a fixed-wing unmanned aerial vehicle (UAV) in search-and-rescue applications. The UAV supports educational systems development and has a 2.1-m wingspan. The wing structure consists of a foam core covered by a carbon-fiber, laminate composite shell. To quantify the wing characteristics, a fiber-optic strain sensor was surface mounted to measure distributed strain. This sensor is based on Rayleigh scattering from local index variations and it is capable of high spatial resolution. The use of the Rayleigh-scattering fiber-optic sensors for distributed measurements is discussed.

  18. Party Membership and Intra-Party Democracy: How Do Members React to Organizational Change within Political Parties? The Case of Belgium

    Full Text Available Facing a crucial legitimacy crisis, many Western European political parties have recently undergone various forms of organizational changes by adopting procedures for increasing intra-democracy: internal ballots, internal referenda, primary elections and so on. Direct democracy is now used in a wide range of decision-making procedures such as candidate and leadership selection (Cross and Katz, 2013. These reforms have pro-vided new opportunities for participation to party members. What happens to more traditional elements of party internal structures when such instruments of intra-party democracy are adopted? And more specifically, how are such changes perceived by the party base? This paper explores the attitudes and behaviors of members with regard to intra-party democracy procedures. On the basis of a case study (Belgium and of an original dataset, the paper explores the political consequences of intra-party democracy. We show that members’ satisfaction with the party and their degree of previous internal activism affect the level of involvement in intra-party democracy activities. However, the dissatisfaction of the party base vis-à-vis of the membership role is growing. Intra-party democratization seems to limit the organizational function of the grass-roots membership to a ‘cheerleading’ role.

    2014-08-01

    Interfacial joining (bonding) is a widely accepted welding process and one of the environmentally benign technologies used in industrial production. As the bonding temperature is lower than the melting point of the parent materials, melting of the latter is kept to a minimum. The process can be based on diffusion bonding, pressure welding, friction welding, ultrasonic bonding, or brazing-soldering, all of which offer many advantages over fusion welding. In addition, surface technologies such as surface modification, spraying, coating, plating, and thin-film formation are necessary for advanced manufacturing, fabrication, and electronics packaging. Together, interfacial joining and surface technology (IJST) will continue to be used in various industrial fields because IJST is a very significant form of environmentally conscious materials processing. The international symposium of IJST 2013 was held at Icho Kaikan, Osaka University, Japan from 27-29 November, 2013. A total of 138 participants came from around the world to attend 56 oral presentations and 36 posters presented at the symposium, and to discuss the latest research and developments on interfacial joining and surface technologies. This symposium was also held to commemorate the 30th anniversary of the Technical Commission on Interfacial Joining of the Japan Welding Society. On behalf of the chair of the symposium, it is my great pleasure to present this volume of IOP Conference Series: Materials Science and Engineering (MSE). Among the presentations, 43 papers are published here, and I believe all of the papers have provided the welding community with much useful information. I would like to thank the authors for their enthusiastic and excellent contributions. Finally, I would like to thank all members of the committees, secretariats, participants, and everyone who contributed to this symposium through their support and invaluable effort for the success of IJST 2013.

  2. XML Structural Join Based on Extended Region Coding

    Science.gov (United States)

    Yang, YANG; Hai-ge, LI

    XML has become a standard technology in exchange of a wide variety of data on web and internet for its structure, label, portability and expansibility. To efficiently query XML documents has been the primary urgent task. At the present time, most of XML index and query are based on encoding the XML document tree, so all kinds of XML encoding schemes are proposed, and region coding is the mainstream coding and used most commonly, such as Dietz coding, Li-Moon coding, Zhang coding, Wan coding, etc. The paper proposes an extended region coding based on region coding. Preorder XML document tree, and take preorder numerical orders of a node's all descendants as the region. When carrying out structural join, if preorder numerical order of a node is in this region, structural relation can be ensured. So this extended region coding can help effectively judge structural relation and the XML document tree needn't be traversed. Furthermore, the better structural join algorithms of XML path queries have received considerable attention recently, and some researchers have proposed some fine algorithms to solve the problem. Stack-Tree-Desc algorithm is one of these fine algorithms, it need separately scan ancestor list and descendant list one time to decide ancestor/descendant structural relation, but some unneeded join nodes still be scanned. For this reason, if some element nodes of ancestor list and descendant list which don't need participate in structural join can be jumped, the query efficiency is enhanced. Therefore, based on Stack-Tree-Desc algorithm an improved algorithm which introduces index structure to avoid scanning unwanted nodes, so ordered scanning is unnecessary, the consuming time of query shortens accordingly. And this improved algorithm can quickly judge structural relation based on extended region coding presented in this paper. Experiment is conducted to test the effectiveness of the extended region coding and the Indexed Stack-Tree-Desc algorithm

    Full Text Available Whereas the first digital revolution of science by digitisation changed the scientific practices of data collection, analysis and reporting of results, the second digital revolution, i.e. open science, will also challenge the current roles of researchers, research organisations, libraries and publishers. From the early days of development, research libraries have joined different networks and been among the most active stakeholders working towards open science. Cohesive networks are needed for coordinated actions and support, whereas bridging networks can provide new approaches and novel information. The Finnish Open Science and Research Initiative is presented in this paper as an example of joining networks, motivating individuals and organisations to deliver high-quality services, infrastructures and competence building to promote a transition towards open science. This paper also presents milestones such as the publication of the academic publishing costs of Finnish research organisations and the maturity level of open science operating cultures in HEIs. Based on the experience of the Finnish open science initiative, joining different networks at the national level on an open mode of operation can significantly speed up the transition towards the era of open science.

They can, however, offer an opportunity for a positive resolution. Relationships in a workplace are generally better and stronger between people who have been able to reach a positive resolution of their disagreement, than they are between people who get along moderately well. However, in disputes involving two antagonistic parties, people often forget that there is actually a third party behind the scenes: the institution. It is sometimes surprising to see that even people holding management responsibilities or hierarchical positions in projects fight each other, and completely forget that they are accountable for the good functioning of CERN.

    Full Text Available Our task is to reflect upon Wagar's idea of a world party. In case such reflections are affected by the recent historical situation of the collapse of communism/existing socialism in 1989 and the implications this has for visions of progressive politics going into the 21st century. This event colors most political thinking, although for many the response has been that existing socialism was not real socialism, or that existing socialism was but the Stalinist deformation that, if avoided in the future, the 1917 project could again be resumed and human history and social relations remade anew. I don't see it that way. What existing socialism stood for in terms of the role of a vanguard party taking state power for the larger good is, now after the fall, I think off the board as a realistic program that can be sold to anyone.

    Full Text Available How to efficiently mimic the wing shape and kinematics pattern of an able hovering living flier is always a concern of researchers from the flapping wing micro aerial vehicles community. In this work, the separate or combined optimizations of wing geometry or/and wing kinematic parameters are systematically performed to minimize the energy of hovering flight, firstly on the basis of analytically extended quasi-steady aerodynamic model by using hybrid genetic algorithm. Before the elaboration of the optimization problem, the parametrization description of dynamically scaled wing with non-dimensional conformal feature of insect-scale rigid wing is firstly proposed. The optimization results show that the combined optimization of wing geometry and kinematic parameters can obtain lower flapping frequency, larger wing geometry parameters and lower power density in comparison with those from other cases of optimization. Moreover, the flapping angle for the optimization involving wing kinematic parameters manifests harmonic shape profile and the pitch angle possesses round trapezoidal profile with certain faster time scale of pitch reversal. The combined optimization framework provides a novel method for the conceptual design of fundamental parameters of biomimetic flapping wing micro aerial vehicle.

  11. Habitat variation and wing coloration affect wing shape evolution in dragonflies.

    Habitats are spatially and temporally variable, and organisms must be able to track these changes. One potential mechanism for this is dispersal by flight. Therefore, we would expect flying animals to show adaptations in wing shape related to habitat variation. In this work, we explored variation in wing shape in relation to preferred water body (flowing water or standing water with tolerance for temporary conditions) and landscape (forested to open) using 32 species of dragonflies of the genus Trithemis (80% of the known species). We included a potential source of variation linked to sexual selection: the extent of wing coloration on hindwings. We used geometric morphometric methods for studying wing shape. We also explored the phenotypic correlation of wing shape between the sexes. We found that wing shape showed a phylogenetic structure and therefore also ran phylogenetic independent contrasts. After correcting for the phylogenetic effects, we found (i) no significant effect of water body on wing shape; (ii) male forewings and female hindwings differed with regard to landscape, being progressively broader from forested to open habitats; (iii) hindwings showed a wider base in wings with more coloration, especially in males; and (iv) evidence for phenotypic correlation of wing shape between the sexes across species. Hence, our results suggest that natural and sexual selection are acting partially independently on fore- and hindwings and with differences between the sexes, despite evidence for phenotypic correlation of wing shape between males and females. © 2013 The Authors.

    In this study, the unsteady flow and acoustic characteristics of a three-dimensional (3D) flapping wing model of Tibicen linnei cicada at forward flight condition are numerically investigated. A single cicada wing is modelled as a membrane with prescribed motion reconstructed from high-speed videos of a live insect. The numerical solution takes a hydrodynamic/acoustic splitting approach: the flow field is solved with an incompressible Navier-Stokes flow solver based on immersed boundary method and the acoustic field is solved with linearized perturbed compressible equations (LPCEs). The 3D simulation allows examination of both directivity and frequency composition of the flapping wing sound in the full space. Along with the flexible wing model, a rigid wing model that is extracted from the real motion is also simulated to investigate the effect of wing flexibility. The simulation results show that the flapping sound is directional; the dominant frequency varies around the wing. The first and second frequency harmonics show different radiation patterns in the rigid and flexible wing cases which are demonstrated to be highly associated with wing kinematics and loadings. Furthermore, the rotation and deformation in the flexible wing is found to help lower the sound strength in all the directions. . © 2017 IOP Publishing Ltd.

    Currently, flapping wing unmanned aerial vehicles (a.k.a., ornithopters or robotic birds) sustain very short duration flight due to limited on-board energy storage capacity. Therefore, energy harvesting elements, such as flexible solar cells, need to be used as materials in critical components, such as wing structures, to increase operational performance. In this paper, we describe a layered fabrication method that was developed for realizing multifunctional composite wings for a unique robotic bird we developed, known as Robo Raven, by creating compliant wing structure from flexible solar cells. The deformed wing shape and aerodynamic lift/thrust loads were characterized throughout the flapping cycle to understand wing mechanics. A multifunctional performance analysis was developed to understand how integration of solar cells into the wings influences flight performance under two different operating conditions: (1) directly powering wings to increase operation time, and (2) recharging batteries to eliminate need for external charging sources. The experimental data is then used in the analysis to identify a performance index for assessing benefits of multifunctional compliant wing structures. The resulting platform, Robo Raven III, was the first demonstration of a robotic bird that flew using energy harvested from solar cells. We developed three different versions of the wing design to validate the multifunctional performance analysis. It was also determined that residual thrust correlated to shear deformation of the wing induced by torsional twist, while biaxial strain related to change in aerodynamic shape correlated to lift. It was also found that shear deformation of the solar cells induced changes in power output directly correlating to thrust generation associated with torsional deformation. Thus, it was determined that multifunctional solar cell wings may be capable of three functions: (1) lightweight and flexible structure to generate aerodynamic forces, (2

    Full Text Available Abstract: In Hungary and Slovakia during 2010-2015 there has been an increase in xenophobic attitudes in society; rightwing and extremist groups are activating there as well. The purpose of this article is to compare the most signifi cant factors which encourage xenophobia. Previously we have identifi ed the types of right-wing organizations and found out their electoral characteristics. We assume that the activities of right-wing extremist organizations infl uence the formation of xenophobic social practices in Hungary and Slovakia, which arise from the range of factors. In this article we used empirical data gained as a result of public opinion polls conducted by the leading research centers in Hungary and Slovakia, by international organizations, as well as statistics of public authorities and civil society institutions. By means of factor analysis, we identifi ed the main directions and forms of activity of right-wing radicals; determined the value of socio-economic dynamics of the country's development; characterized the attitude of society, the law and the ruling elite to the problems of xenophobia and right-wing radicalism. Among the most infl uential factors we identifi ed: open propaganda of nationalist ideas; constitutional priority of the ethnic majority interests; parliamentary status of rightwing parties; condoning the activities of right-wing radicals by the ruling elite, the courts and the police. The comparison of factors stimulating xenophobic practices in Hungary and Slovakia didn’t confi rm the hypothesis of common signifi cant infl uence of the economic crisis, lack of education and political passivity on the formation of xenophobic practices among young people. The professional frustration of provincial youth discovered itself as a cumulative socioeconomic factor.

    2002-09-01

    Full Text Available This paper describes the origin and evolution of two Chilean political parties (the Radical Party and the Christian Democrat Party through the analysis of the social networks that originated and composed them. The aim of this study is to propose a model of national political cultures on the basis of the structure of social networks related to power and of the symbol system, which legitimizes it. The structure of social networks, horizontal and vertical, are based on reciprocal or redistributive forms of exchange, on what is being exchanged and on the articulation between networks. In every society there are symmetrical and asymmetrical exchanges, which produce horizontal and vertical networks. These networks interact among themselves to form the social fabric. The dominance of some over others and how they combine, delineate the character of the political culture (authoritarian vs. egalitarian. Chile is a multiparty country within which there are cohorts of horizontal groups of friends, who informally exercise a central control over their members and create invisible boundaries setting them apart from others, in which leadership is under constrains. The result is both a strong presidential system based on an almost fanatic legitimacy, combined with factionalism and a strong parliamentary system.

    Full Text Available  The task of calculation of optimum circulation distribution along wingspan of complex shape wings is considered. For solving this problem Glauert-Trefts’s equation and its modifications are used. Calculations are carried out for both sweptback and forward-swept wings. It is shown that optimum circulation distribution depends on the sweep angle χ and  on the chord b(z distribution along wingspan. Some aerodynamic coefficients such as induced drag coefficient CDi and pitching moment coefficient CmZ are calculated for wings of different shape. The comparison of wings performances is done. In order to obtain the minimum wing induced drag with the given lift force it is very important to determine how the circulation should change along the wingspan. Results obtained by E. K. Karafoli G.F. Burago and others are used. A set of theoretical generalizations and modifications of formulas for aerodynamic coefficients are obtained. These results permit to compare aerodynamic performances of sweptback and forward-swept wings. Modified Glauert-Trefts’s integral-differential equation is formulated for wings of complex shape.

    Drosophila melanogaster is an important organism used in many fields of biological research such as genetics and developmental biology. Drosophila wings have been widely used to study the genetics of development, morphometrics and evolution. Therefore there is much interest in quantifying wing structures of Drosophila. Advancement in technology has increased the ease in which images of Drosophila can be acquired. However such studies have been limited by the slow and tedious process of acquiring phenotypic data. We have developed a system that automatically detects and measures key points and vein segments on a Drosophila wing. Key points are detected by performing image transformations and template matching on Drosophila wing images while vein segments are detected using an Active Contour algorithm. The accuracy of our key point detection was compared against key point annotations of users. We also performed key point detection using different training data sets of Drosophila wing images. We compared our software with an existing automated image analysis system for Drosophila wings and showed that our system performs better than the state of the art. Vein segments were manually measured and compared against the measurements obtained from our system. Our system was able to detect specific key points and vein segments from Drosophila wing images with high accuracy.

  3. Novel Control Effectors for Truss Braced Wing

    Science.gov (United States)

    White, Edward V.; Kapania, Rakesh K.; Joshi, Shiv

    2015-01-01

    At cruise flight conditions very high aspect ratio/low sweep truss braced wings (TBW) may be subject to design requirements that distinguish them from more highly swept cantilevered wings. High aspect ratio, short chord length and relative thinness of the airfoil sections all contribute to relatively low wing torsional stiffness. This may lead to aeroelastic issues such as aileron reversal and low flutter margins. In order to counteract these issues, high aspect ratio/low sweep wings may need to carry additional high speed control effectors to operate when outboard ailerons are in reversal and/or must carry additional structural weight to enhance torsional stiffness. The novel control effector evaluated in this study is a variable sweep raked wing tip with an aileron control surface. Forward sweep of the tip allows the aileron to align closely with the torsional axis of the wing and operate in a conventional fashion. Aft sweep of the tip creates a large moment arm from the aileron to the wing torsional axis greatly enhancing aileron reversal. The novelty comes from using this enhanced and controllable aileron reversal effect to provide roll control authority by acting as a servo tab and providing roll control through intentional twist of the wing. In this case the reduced torsional stiffness of the wing becomes an advantage to be exploited. The study results show that the novel control effector concept does provide roll control as described, but only for a restricted class of TBW aircraft configurations. For the configuration studied (long range, dual aisle, Mach 0.85 cruise) the novel control effector provides significant benefits including up to 12% reduction in fuel burn.

    Using entanglement of assistance, we establish a general polygamy inequality of multi-party entanglement in arbitrary dimensional quantum systems. For multi-party closed quantum systems, we relate our result with the monogamy of entanglement to show that the entropy of entanglement is an universal entanglement measure that bounds both monogamy and polygamy of multi-party quantum entanglement.

    The evolution of butterfly wing colouration is strongly affected by its multiple functions and by the correlated evolution of wing colour elements. Both factors may prevent local adaptation to ecological conditions. We investigated one aspect of wing colouration, the degree of dorsal wing

  15. Numerical analysis of supersonic transport wings

    OpenAIRE

    Yamazaki, Tetsuo; Uchida, Takashi; 山崎 哲夫; 内田 隆志

    1992-01-01

    Numerical analysis of supersonic transport wings was carried out. The drag reduction obtained by warped wing design technique is from 0.0006 to 0.0010 in supersonic cruise condition. It is also clarified that the drag reduction by use of Euler analysis is less than that by the linear method, because the flow mechanism in supersonic region is essentially non-linear. Finally it is shown that cranked arrow wing-body configuration has the best lift to drag ratio in supersonic cruise condition in ...

  16. The plane problem of the flapping wing

    Science.gov (United States)

    Birnbaum, Walter

    1954-01-01

    In connection with an earlier report on the lifting vortex sheet which forms the basis of the following investigations this will show how the methods developed there are also suitable for dealing with the air forces for a wing with a circulation variable with time. The theory of a propulsive wing flapping up and down periodically in the manner of a bird's wing is developed. This study shows how the lift and its moment result as a function of the flapping motion, what thrust is attainable, and how high is the degree of efficiency of this flapping propulsion unit if the air friction is disregarded.

    Holst, Terry L.; Olsen, Thomas H.; Kwak, Dochan (Technical Monitor)

    2001-01-01

    The wing-body aerodynamics data base consists of a series of CFD (Computational Fluid Dynamics) simulations about a generic wing body configuration consisting of a ogive-circular-cylinder fuselage and a simple symmetric wing mid-mounted on the fuselage. Solutions have been obtained for Nonlinear Potential (P), Euler (E) and Navier-Stokes (N) solvers over a range of subsonic and transonic Mach numbers and angles of attack. In addition, each solution has been computed on a series of grids, coarse, medium and fine to permit an assessment of grid refinement errors.

    Science.gov (United States)

    2001-01-01

    Inflatable Wing project personnel prepare a deployable, inflatable wing technology demonstrator experiment flown by the NASA Dryden Flight Research Center, Edwards, California. The inflatable wing project represented a basic flight research effort by Dryden personnel. Three successful flights of the I2000 inflatable wing aircraft occurred. During the flights, the team air-launched the radio-controlled (R/C) I2000 from an R/C utility airplane at an altitude of 800-1000 feet. As the I2000 separated from the carrier aircraft, its inflatable wings 'popped-out,' deploying rapidly via an on-board nitrogen bottle. The aircraft remained stable as it transitioned from wingless to winged flight. The unpowered I2000 glided down to a smooth landing under complete control.

Implementation of the joining method with respect to the construction of modular cellular structures that comprise BMG Composites is also discussed.

  20. AFM Study of Structure Influence on Butterfly Wings Coloration

    Directory of Open Access Journals (Sweden)

    Dinara Sultanovna Dallaeva

    2012-01-01

    Full Text Available This study describes the structural coloration of the butterfly Vanessa Atalanta wings and shows how the atomic force microscopy (AFM can be applied to the study of wings morphology and wings surface behavior under the temperature. The role of the wings morphology in colors was investigated. Different colors of wings have different topology and can be identified by them. AFM in semi-contact mode was used to study the wings surface. The wing surface area, which is close to the butterfly body, has shiny brown color and the peak of surface roughness is about 600 nm. The changing of morphology at different temperatures is shown.
