Virtual Prototyping of a Compliant Spindle for Robotic Deburring

At the current state-of-the-art, Robotic Deburring (RD) has been successfully adopted in many industrial applications, but it still needs improvements in terms of final quality. In fact, the effectiveness of a RD process is highly influenced by the limited accuracyof the robot motions and by the unpredictable variety of burr size/shape. Tool compliance partially solves the problem, although dedicated engineering design tools are strictly needed, in order to identify those optimized parameters and RD strategies that allow achieving the best quality and cost-effectiveness. In this context, the present paper proposes a CAD-based Virtual Prototype (VP) of a pneumatic compliant spindle, suitable to assess the process efficiency in different case scenarios. The proposed VP is created by integrating a 3D multi-body model of the spindle mechanical structure with the behavioural model of the process forces, as adapted from previous literature. Numerical simulations are provided, concerning the prediction of both cutting forces and surface finishing accuracy
Digital Natives: Its Characteristics and Challenge to the Library Service Quality

Digital natives which always connect to the world through their gadgets have special needs for gathering information. Do libraries which in the past can be said as the sources of information can satisfy their needs? What should libraries do, so that they can answer those needs? Those queries are the prominent questions to be answered in this paper. In this paper we describe the digital natives&#65533; charac-teristics when they use their PC and gadgets. The data were collected from 460 university students in Surabaya. We also measure the library service quality (LibQual) for five university libraries in Surabaya. Moreover, using K-means, we also clustered the respondents into two groups, i.e, the first group is the ones who attach to their gadgets, and the second group is the ones who do not attach to their gadgets. For the first groupthe library online information and for the second group, the operational service are the most important factors for measuring the LibQua
Games and Multimedia Implementation on Heroic Battle of Surabaya: An Android Based Mobile Device Application

Number of users of who use mobile devices and other handheld devices is rapidly increased (such as smartphones and tablet computers). This phenomena has changed the lifestyle of many people, especially in the ease of access to information. For example, access to any business information, political information, tourism information, as well as educational information. Education has also entered a new era, where books and other teaching materials, are not only presented using paper media but also in electronic form. Student can easily access that electronic information using computer/laptop or smartphone/tablet PC. So now, learning can be delivered in a more interesting and interactive media and model. It becomes new challenges for education, especially in teaching nation history, where education in paper material is no longer quite interesting. Therefore, new teaching media is required, that more interesting and interactive to the student. At this time, there are not many applications on mobile devices that explore education especially on heroic history of Indonesia. On the other hand, the education of heroic history become more necessary today, especially for young people. To answer this challenge, in this research we like to build an application software based on android mobile devices that contain education the history of the heroic battles 10 November 1945 in Surabaya. The application will provide the information of battle history, and also games and multimedia interactive such as sound, video streaming that built on android based mobile device. With this educational applications we expected that everyone especially young people can learning the knowledge about the history of the heroic battle 10 November 1945 Surabaya in the mobile device based on Android in interactive educational applications that provide a thorough understanding and fascinating history of the events surrounding the battle, and also exploring the historic sites in Surabaya and found fascinating city of Surabaya
FullSWOF: A software for overland flow simulation / FullSWOF : un logiciel pour la simulation du ruissellement

9 pagesInternational audienceOverland flow on agricultural fields may have some undesirable effects such as soil erosion, flood and pollutant transport. To better understand this phenomenon and limit its consequences, we developed a code using state-of-the-art numerical methods: FullSWOF (Full Shallow Water equations for Overland Flow), an object oriented code written in C++. It has been made open-source and can be downloaded from http://www.univ-orleans.fr/mapmo/soft/FullSWOF/. The model is based on the classical system of Shallow Water (SW) (or Saint-Venant system). Numerical difficulties come from the numerous dry/wet transitions and the highly-variable topography encountered inside a field. It includes runon and rainfall inputs, infiltration (modified Green-Ampt equation), friction (Darcy-Weisbach and Manning formulas). First we present the numerical method for the resolution of the Shallow Water equations integrated in FullSWOF_2D (the two-dimension version). This method is based on hydrostatic reconstruction scheme, coupled with a semi-implicit friction term treatment. FullSWOF_2D has been previously validated using analytical solutions from the SWASHES library (Shallow Water Analytic Solutions for Hydraulic and Environmental Studies). Finally, FullSWOF_2D is run on a real topography measured on a runoff plot located in Thies (Senegal). Simulation results are compared with measured data. This experimental benchmark demonstrate the capabilities of FullSWOF to simulate adequately overland flow. FullSWOF could also be used for other environmental issues, such as river floods and dam-breaks
SWASHES: A library for benchmarking in hydraulics / SWASHES : une bibliothèque de bancs d'essai en hydraulique

8 pagesInternational audienceNumerous codes are being developed to solve Shallow Water equations. Because they are used in hydraulics and environmental studies, their capability to simulate properly flow dynamics is essential to guarantee infrastructure and human safety. Hence, validating these codes and the associated numerical methods is an important issue. Analytic solutions would be excellent benchmarks for these issues. However, analytic solutions to Shallow Water equations are rare. Moreover, they have been published on an individual basis over a period of more than five decades, making them scattered through the literature. In this paper, a significant number of analytic solutions to the Shallow Water equations is described in a unified formalism. They encompass a wide variety of flow conditions (supercritical, subcritical, shock ...), in 1 or 2 space dimensions, with or without rain and soil friction, for transitory flow or steady state. An original feature is that the corresponding source codes are made freely available to the community (http://www.univ-orleans.fr/mapmo/soft/SWASHES), so that users of Shallow Water based models can easily find an adaptable benchmark library to validate their numerical methods
How to manufacture a sustainable future for 9 billion people in 2050

This is a conference paper. The definitive version is available at: http://link.springer.com/chapter/10.1007/978-981-4451-48-2_1#There is a growing body of evidence which increasingly points to serious and irreversible ecological consequences if current unsustainable manufacturing practices and consumption patterns continue. Recent years have seen a rising awareness leading to the generation of both national and international regulations, resulting in modest improvements in manufacturing practices. These incremental changes however are not making the necessary progress towards eliminating or even reversing the environmental impacts of global industry. Therefore, a fundamental research question is: ’How can we meet the long term demand of our growing global population, and in this context, what are the key challenges for the future of manufacturing industry?’ A common approach adopted in such cases is to utilise foresighting exercises to develop a number of alternative future scenarios to aid with long-term strategic planning. This paper presents the results of one such study to create a set of ’SMART Manufacturing Scenarios’ for 2050
Evolution in ecodesign and sustainable design methodologies

This is a conference paper. The definitive version is available at: http://link.springer.com/chapter/10.1007/978-981-4451-48-2_6The majority of the environmental impact of a product is decided during the design phase, and as such there has been a rapid growth in generation of methodologies and tools that aim to improve design and include sustainability considerations in product development. Although these methodologies and tools have introduced measurable benefits, in most cases they have been incremental in nature as opposed to producing radical ‘Factor X’ improvements. This highlights the need for a careful analysis of existing sustainable design methods to identify their shortcomings and to enable a greater understanding of how to unlock the full potential of design improvements. This paper provides a brief overview of the evolution of ecodesign and its extension into sustainable design. It assesses the key influencing factors of current practice and identifies a number of future research challenges, promoting the next stage in its development in which sustainability will become a ubiquitous part of the design process
Working through the layers: Curriculum implementation in language education

This chapter presents findings on English Language instruction at the lower primary level in the context of policies for curricular innovation at national, school and classroom levels. The focus is on policies which connect national and school levels, and on how they might be interpreted when implemented in multiple schools within Singapore's educational system. Referring to case studies in two schools and to individual lesson observations in 10 schools, we found much agreement with national policies in terms of curriculum (i.e. lesson content and activity selection), leading to great uniformity in the lessons taught by different teachers in different schools. In addition, we found that schools had an important mediating influence on implementation of national policies. However, adoptions and adaptations of policy innovations at the classroom level were somewhat superficial as they were more related to changes in educational facilities and procedures than in philosophies.Full Tex
User-Centred BCI Videogame Design

International audienceThis chapter aims to offer a user-centred methodological framework to guide the design and evaluation of Brain-Computer Interface videogames. This framework is based on the contributions of ergonomics to ensure these games are well suited for their users (i.e., players). It provides methods, criteria and metrics to complete the different phases required by ae human-centred design process. This aims to understand the context of use, specify the user needs and evaluate the solutions in order to define design choices. Several ergonomic methods (e.g., interviews, longitudinal studies, user based testing), objective metrics (e.g., task success, number of errors) and subjective metrics (e.g., mark assigned to an item) are suggested to define and measure the usefulness, usability, acceptability, hedonic qualities, appealingness, emotions related to user experience, immersion and presence to be respected. The benefits and contributions of the user centred framework for the ergonomic design of these Brain-Computer Interface Videogames are discussed
Exploring schools' use of natural spaces

This chapter focuses on the changing ways in which schools are using natural spaces as part of their pupils’ learning experience. We suggest that learning in natural spaces has undergone something of a renaissance in recent times, and explore the reasons that this might be so. We then examine ways in which schools and other practitioners are using outdoor spaces for play, for non-curricular and for curricular learning. The chapter draws on a range of countries for examples that show how a nation’s cultural ideas about the outdoors can be incorporated into a country’s outdoor learning, and how other ideas travel across boundaries to be interpreted in different practical ways. Within these sections, we consider different theoretical underpinnings that inform learning outside. Finally, the benefits of and challenges to outdoor learning are considered
Mixing of rhyolite, trachyte and basalt magma erupted from a vertically and laterally zoned reservoir, composite flow P1, Gran Canaria

The 14.1 Ma composite welded ignimbrite P1 (45 km3 DRE) on Gran Canaria is compositionally zoned from a felsic lower part to a basaltic top. It is composed of four component magmas mixed in vertically varying proportions: (1) Na-rhyolite (10 km3) zoned from crystal-poor to highly phyric; (2) a continuously zoned, evolved trachyte to sodic trachyandesite magma group (6 km3); (3) a minor fraction of Na-poor trachyandesite (<1 km3); and (4) nearly aphyric basalt (26 km3) zoned from 4.3 to 5.2 wt% MgO. We distinguish three sites and phases of mixing: (a) Mutual mineral inclusions show that mixing between trachytic and rhyolitic magmas occurred during early stages of their intratelluric crystallization, providing evidence for long-term residence in a common reservoir prior to eruption. This first phase of mixing was retarded by increasing viscosity of the rhyolite magma upon massive anorthoclase precipitation and accumulation. (b) All component magmas probably erupted through a ring-fissure from a common upper-crustal reservoir into which the basalt intruded during eruption. The second phase of mixing occurred during simultaneous withdrawal of magmas from the chamber and ascent through the conduit. The overall withdrawal and mixing pattern evolved in response to pre-eruptive chamber zonation and density and viscosity relationships among the magmas. Minor sectorial variations around the caldera reflect both varying configurations at the conduit entrance and unsteady discharge. (c) During each eruptive pulse, fragmentation and particulate transport in the vent and as pyroclastic flows caused additional mixing by reducing the length scale of heterogeneities. Based on considerations of magma density changes during crystallization, magma temperature constraints, and the pattern of withdrawal during eruption, we propose that eruption tapped the P1 magma chamber during a transient state of concentric zonation, which had resulted from destruction of a formerly layered zonation in order to maintain gravitational equilibrium. Our model of magma chamber zonation at the time of eruption envisages a basal high-density Na-poor trachyandesite layer that was overlain by a central mass of highly phyric rhyolite magma mantled by a sheath of vertically zoned trachyte-trachyandesite magma along the chamber walls. A conventional model of vertically stacked horizontal layers cannot account for the deduced density relationships nor for the withdrawal pattern
Barotropic tides in the Northeast Atlantic inferred from moored current meter data

Current data obtained from 7 moorings in the Northeast Atlantic in the course of many years are analysed with respect to semi-diurnal barotropic and baroclinic tides and diurnal barotropic tides. For semi-diurnal tides M2 and S2 the energy distribution is usually dominated by the barotropic mode; only in a few cases does the first-order baroclinic mode contain higher energy. Barotropic tidal ellipse orientations are found to be consistent with results from earlier tide gauge observations in this area. Significant deviations occur, however, in amplitudes. Results for the diurnal component K1 are also presented. With few exceptions, tides are found to be progressive waves in this area. The current ellipse pattern is similar to results obtained indirectly by Cartwright, Edden, Spencer et al. [1980] from tide gauge observations
Prospecting for New Questions: Integrating Geophysics to Define Anthropological Research Objectives and Inform Excavation Strategies at Monumental Sites

Geophysical data have the potential to significantly contribute to archaeological research projects when effectively integrated with more traditional methods. Although pre‐existing archaeological questions about a site may be answered using geophysical methods, beginning an investigation with an extensive geophysical survey can assist in understanding the function and archaeological potential of a site, and may even transform preconceptions about the type and spatial organisation of features that are present. In this way, these prospection tools not only accurately locate and map features to allow recovery of cultural material for identification and dating, we argue that they can go much further, allowing us to prospect for new and appropriate archaeological and anthropological research questions. Such an approach is best realised when geophysical and traditional archaeologists work together to define new objectives and strategies to address them, and by maintaining this collaboration to allow continual feedback between geophysical and archaeological data. A flexible research design is therefore essential in order to allow the methodologies to adapt to the site, the results, and the questions being posed. This methodology is demonstrated through two case studies from mound sites in southeast USA: the transitional Mississippian Washausen site in Illinois; and the Middle Woodland Garden Creek site in North Carolina. In both cases, integrating geophysical methods throughout the archaeological investigations has resulted in multiple phases of generating and addressing new research objectives. Although clearly beneficial at these two mound sites in southeast USA, this interdisciplinary approach has obvious implications well beyond these temporal and geographical areas.

Fracture testing of a self-healing polymer composite

Inspired by biological systems in which damage triggers an autonomic healing response, we have developed a polymer composite materials that can heal itself when cracked. This paper summarizes the self-healing concept for polymeric composite materials and investigates fracture mechanics issues consequential to the development and optimization of this new class of materials. The self-healing material under investigation is an epoxy matrix composite, which incorporates a microencapsulated healing agent that is released upon crack intrusion. Polymerization of the healing agent is triggered by contact with an embedded catalyst. The effects of size and concentration of catalyst and microcapsules on fracture toughness and healing efficiency are investigated. In all cases the addition of microcapsules significantly toughens the neat epoxy. Once healed, the self-healing polymer recovers as much as 90% of its virgin fracture toughness.published or submitted for publicationis peer reviewe
Evolutionary Algorithms as fitness function debuggers

International audienceAll Evolutionary Algorithms experienced practitioners emphasize the need for a careful design of the fitness function. It is commonly heard~ for instance, that "If there is a bug in your fitness function, the EA will find it". This paper presents a case study of such a situation in the domain of geophysical underground identification: some weird solutions are found by the Evolutionary Algorithm, obviously physically absurd, but fulfilling almost perfectly the geophysical criterion
Searches for transverse momentum dependent flow vector fluctuations in Pb-Pb and p-Pb collisions at the LHC

The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at sNN−−−√=2.76 TeV and p-Pb collisions at sNN−−−√=5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region |η| < 0.8 as a function of centrality and transverse momentum pT using two observables, to search for evidence of pT-dependent flow vector fluctuations. For Pb-Pb collisions at 2.76 TeV, the measurements indicate that pT-dependent fluctuations are only present for the second order flow vector. Similar results have been found for p-Pb collisions at 5.02 TeV. These measurements are compared to hydrodynamic model calculations with event-by-event geometry fluctuations in the initial state to constrain the initial conditions and transport properties of the matter created in Pb–Pb and p–Pb collisions
MSSM Baryogenesis and Electric Dipole Moments: An Update on the
  Phenomenology

We explore the implications of electroweak baryogenesis for future searches
for permanent electric dipole moments in the context of the minimal
supersymmetric extension of the Standard Model (MSSM). From a cosmological
standpoint, we point out that regions of parameter space that over-produce
relic lightest supersymmetric particles can be salvaged only by assuming a
dilution of the particle relic density that makes it compatible with the dark
matter density: this dilution must occur after dark matter freeze-out, which
ordinarily takes place after electroweak baryogenesis, implying the same degree
of dilution for the generated baryon number density as well. We expand on
previous studies on the viable MSSM regions for baryogenesis, exploring for the
first time an orthogonal slice of the relevant parameter space, namely the
(tan\beta, m_A) plane, and the case of non-universal relative gaugino-higgsino
CP violating phases. The main result of our study is that in all cases lower
limits on the size of the electric dipole moments exist, and are typically on
the same order, or above, the expected sensitivity of the next generation of
experimental searches, implying that MSSM electroweak baryogenesis will be soon
conclusively tested.Comment: 23 pages, 10 figures, matches version published in JHE
Fine Tuning in General Gauge Mediation

We study the fine-tuning problem in the context of general gauge mediation.
Numerical analyses toward for relaxing fine-tuning are presented. We analyse
the problem in typical three cases of the messenger scale, that is, GUT
($2\times10^{16}$ GeV), intermediate ($10^{10}$ GeV), and relatively low energy
($10^6$ GeV) scales. In each messenger scale, the parameter space reducing the
degree of tuning as around 10% is found. Certain ratios among gluino mass, wino
mass and soft scalar masses are favorable. It is shown that the favorable
region becomes narrow as the messenger scale becomes lower, and tachyonic
initial conditions of stop masses at the messenger scale are favored to relax
the fine-tuning problem for the relatively low energy messenger scale. Our
spectra would also be important from the viewpoint of the $\mu-B$ problem.Comment: 22 pages, 16 figures, comment adde
