description: Rotary tables as components of 4-axis measuring devices provide a quick rotary positioning in geometry measurements, but the non-trivial error motions need to be determined and compensated. This paper presents a new solution for the error mapping, which calibrates the rotary table, the 3-axis measuring device and the artifact (circular ball plate) simultaneously. Multi-measuring and approximation techniques are introduced to identify and quantify the error motions based on obtained point clouds. A mathematical model covers all the deviation sources, occurring at the movement of a rotary axis. Simulations and experimental results verify and validate the solution. The simple and flexible calibration setup together with the developed evaluation procedure enable a compensation of rotary table/axis deviations in a wide application field.

description: In dem Vortrag werden zwei kürzlich erschienene Stellungnahmen und ein Diskussionspapier der Leopoldina zur Biodiversität in der Agrarlandschaft kritisch kommentiert. Dem hier vermittelten Bild einer ursächlichen Rolle des chemischen Pflanzenschutzes beim Rückgang von Biodiversität wird entgegengehalten, dass es dafür keine hinreichenden Belege gibt. Die Kritik richtet sich gegen die einseitige Bewertung des Pflanzenschutzes allein aus dem Blickwinkel der Umweltwissenschaften. Es wird kritisiert, dass dieser verengte Blickwinkel in den Schriften der Leopoldina den unverzichtbaren Nutzen des Pflanzenschutzes und die erheblichen Verbesserungen bei der Risikoverminderung chemischer Pflanzenschutzmittelanwendungen gänzlich ausblendet. Darüber hinaus werden gravierende Verletzungen wissenschaftlicher Standards aufgezeigt, die sich in einer selektiven Zitier- und Argumentationsweise zeigen. Die bestehende Verantwortung der Leopoldina, Empfehlungen an die Politik auf der Grundlage objektiver Wissenschaft zu formulieren, wird angemahnt.

description: Die Pflanzenzüchtung erzeugt kontinuierlich genetisch verbesserte Sorten. Im Vortrag wird zunächst gezeigt, dass entgegen gängiger Paradigmen hoher Ertrag, Ressourceneffizienz und Umweltstabilität durchaus vereinbar sind. Am Beispiel der Züchtung für den ökologischen Landbau wird deutlich gemacht, wie Zuchtprozesse effizient gestaltet und Zielkonflikte aufgelöst werden können, wenn Zuchtziele eindeutig definiert sind. Etablierte Züchtungsprogramme bieten hierfür hohe Flexibilität. Erfolge bei der Nutzung von genetischen Ressourcen zur Verbreiterung der genetischen Diversität für Merkmale der Zukunft werden vorgestellt. Weiterhin wird die Bedeutung neuer Züchtungstechnologien für die genetische Verbesserung unserer Kulturpflanzen beispielhaft dargelegt und vor allem, welch hohe Bedeutung dem Feldversuch in diesem Zusammenhang zukommt.

It is the first algorithm that can build the index while implicitly sorting the sequences in the reverse (complement) lexicographical order without a separate sorting step. The implementation is among the fastest for indexing short reads and the only one that practically works for reads of averaged kilobases in length.

Holistic approximation of combined surface data

Subjects: subject: Holistic approximation

subject: 600

description: Modern micro-production processes demand fast and robust inspection techniques up to 100% inspection rates. For instance, a fast acquisition of the objects surface in the needed precision and density can be realized by optical measurement systems. In order to extract the relevant geometric quantities from the surface data of prismatic workpieces, the measured data points need to be assigned to the nominal geometric primitives, e. g. cylinder, plane or sphere. For this purpose, an automatable algorithm is desired, which assigns all measured points to the corresponding geometric elements and minimizes the measurement uncertainty. Such an optimal segmentation routine of combined geometric data can either be performed by rating neighboring measurement points based on their curvature or by a holistic approximation. Whereas the first approach is sensitive to noisy data and not able to distinguish between spheres and cylinders with certain radii, the holistic approximation in combination with further statistical methods promises an automatic detection of outliers. In order to analyze the achievable measurement uncertainty with the holistic approximation approach for an object geometry composed by three-dimensional base elements (cylinder, torus, plane), the method is applied to determine the geometric features of micro deep-drawing dies. For verification, the measured geometry of the object is simulated including uniformly distributed noise within a range of ±2.5 μm. As a result, the determined radius of the cylinder (defined to 412 μm) has a standard uncertainty due to random errors below 11 nm and an uncertainty due to systematic errors less than 1.1 nm. Furthermore, real tactile measurement data are evaluated to validate the holistic approximation. In comparison to certified analysis software, which requires a manual segmentation, the results show differences below 0.25 μm for the cylinder diameter. The increased measurement deviations are caused by assumptions of the model-based evaluation, which is essential for the automated data processing. However, the achievable uncertainty qualifies the holistic approximation for a robust and automated evaluation of geometric tolerances in the field of micro-production.

description: The purpose of this investigation is not only to collect the orality of migrants but to make their "social knowledge" (Curcio, 2017). In order to extract this social knowledge, the use of the most functional qualitative method has been resorted to being able to come into contact with nearby but "submerged" worlds. Field work has been characterized, in fact, for the involvement of 37 persons in in-depth interviews and two focus groups (one at a CAS and another at one of the migrant households). Studying the temporary nature of migrant living in such spaces meant understanding the social criticalities of contemporary space and time. The words produced by Z., or J. and many others afflicted bodies, have resigned concepts such as border, margin, zone producing a crisis in the spatial sociological tradition. The theoretical crisis produced by these speeches could be investigated as life effects produced by the "migrant areas" through an ethnographic approach (Garfinkel 1964, Goffman, 1969, De Martino 1975, Geertz 2006, Palidda 2004). Thus, the analysis of categories of mobility, segregation and resistance was defined by defining the limits and potential of migratory tactics in urban transformation and subjectivity production. This study could not foresee the examination of the access, sharing and abandonment of migrant areas that are in fact determined by the entry and exit processes of border control zone (Bigo, 2013). In this sense, the sicuritation practices (Bigo, 2013) established by the Italian authorities and the transformation - including in the field of rights - of migrant labor have been examined. Analyzing the transformations - in quantity and quality - of the migrant work of the communities of the Piana del Sele, defining also the "social housing" access criteria. In this sense, it was useful to accommodate discursive transformations in segregation practices operated by local institutions, stakeholders and private individuals in the management of migrant flows. The research work has also focused on the investigation of governance strategies and control of migrant bodies and the deepening of the resilience practices that the migrants themselves implement. It was necessary to analyze the forms of migrant labor in the late-liberal system (Raimondi 2004, Ricciardi 2004) in order to achieve the objectives listed above. Migrants become a flexible absence (Palidda 2012, R. Sennet 2002) in the specific production of contemporary work. The precarious state of "migrant work" (Raimondi 2004; Ricciardi 2004) becomes an anticipatory and constituent formula for the global process of late-liberal (Palidda 2012). [edited by author]

description: The capability of generating terajets using 3D dielectric cuboids working at terahertz (THz) frequencies (as analogues of nanojets in the infrared band) are introduced and studied numerically. The focusing performance of the terajets are evaluated in terms of the transversal full width at half maximum along x- and y- directions using different refractive indexes for a 3D dielectric cuboid with a fixed geometry, obtaining a quasi-symmetric terajet with a subwavelength resolution of ~0.46λ0 when the refractive index is n = 1.41. Moreover, the backscattering enhancement produced when metal particles are introduced in the terajet region is demonstrated for a 3D dielectric cuboid and compared with its 2D counterpart. The results of the jet generated for the 3D case are experimentally validated at sub-THz waves, demonstrating the ability to produce terajets using 3D cuboids.

Angular-Dependent Radius Measurements at Rotating Objects Using Underdetermined Sensor Systems

Subjects: subject: Inverse Problem
subject: measurement uncertainty
subject: optical radius measurement

subject: systematic and random errors
subject: 600

description: Precise and contactless shape measurements of rotating objects is important, e.g., for monitoring and controlling the manufacturing quality in lathes. For this purpose, multisensor and single-sensor approaches based on optical distance and surface velocity measurements are state-of-the-art techniques. Two- and single-sensor systems are particularly promising to measure the angular-dependent radius of the cross section of the rotating object in a scanning regime with minimal optical access. Since a comparison between the different sensor systems is missing, the potential of these underdetermined sensor systems is unclear. In addition, displacements of the rotational axis and sensor misalignments are suspected to be crucial error sources, but the error is unknown. For this reason, an error analysis is performed regarding the resulting systematic error and the random error for the two- and single-sensor systems. As a result, the different sensor systems have an equal cross-sensitivity with respect to lateral displacements of the rotational axis from the sensor axes, but the two-sensor approach has the lowest sensitivity regarding sensor misalignments. For the studied measurement conditions, the systematic error dominates the sensor noise for the two-sensor system and the single-sensor system with combined distance and velocity measurement at an object mean radius >6 mm. The smallest total measurement uncertainty is obtained with the two-sensor system. Finally, the relevance of systematic error depends on the utilization, i.e., for instance on the absolute rotor radius, the stability of the rotor axis, the sensor position, the accuracy of the sensor alignment, and the uncertainty of the distance and/or velocity measurements.
Geometry Measurement of Submerged Metallic Micro-Parts Using Confocal Fluorescence Microscopy

description: The in situ geometry measurement of microstructures in the laser chemical machining (LCM) manufacturing process places high demands on measurement systems because the specimen is submerged in a closed fluid circuit. The steep slopes of the manufactured micro-components and the general lack of accessibility hinder the use of standard techniques such as tactile measurement or conventional confocal microscopy. A technique based on confocal fluorescence microscopy shows promise for increasing the measurability on metallic surfaces with large curvatures. By applying an intensely scattering fluorescent coating to the specimen, the surface position can be determined by the change in fluorescence signal at the boundary between specimen and coating. In contrast to the currently tested thin coatings (<100 μm) the measurements in layers thicker than 1 mm, as required for in situ application at the LCM process, show distinct dependencies on the fluorescent medium in terms of concentration and index of refraction. Hence, a fundamentally different signal evaluation approach based on a physical model of the fluorescence signal is needed to extract the surface position information from the detected fluorescence intensity signal. For the purpose of validation, the measurement of a step geometry is performed under the condition of a thick fluid layer and referenced with a tactile measurement. As a result, the model-based approach is shown to be suitable to detect the geometry parameter step height with an uncertainty of 8.8 μm or a step submerged in a fluid layer with a thickness of 2.3 mm.

title: The provision of rural public transport services in Britain with particular reference to the role of local authorities in Scotland
Creators: name: Clyne, J. Fraser
Publisher: name: University of Glasgow
Year: 1979
Subjects: subject: Transportation, Area planning & development.

description: Top tier local authorities in Britain currently have an important role to play in the planning of the provision of public transport in rural areas. However, the nature of this role as it has been interpreted, particularly by certain Regional Councils in Scotland, is questioned in this study. The nature of relationships between central and local government as they exist in Scotland are considered to be a hindrance to the achievement of effective rural transport planning. Many of the difficulties experienced in this sphere could be eradicated by the extension to Scotland of the duties placed upon County Councils in England and Wales under the 1978 Transport Act, namely to prepare annual Public Transport Plans. The Scottish Bus Group as the main provider of rural transport facilities in this country is also criticised for failing to adopt an aggressive approach to the marketing of their services. The benefits accruing from the partnership between the Group and local authorities are highlighted, but the potential for greater development emerging from this relationship is shown to remain untapped. The greater responsibilities recently given to the Traffic Commissioners are also investigated and it is suggested that without an adequate research staff to provide them with the necessary analyses of local authority and Bus Group plans, the Commissioners will never fully realise their effectiveness in the rural transport planning framework. The detailed probe into the role adopted by Grampian Regional Council brings to the surface the main deficiency of current planning procedures as far as they relate to rural public transport, i.e. the failure of the local authority to adopt a consumer oriented 'needs-based' approach to the problem. Without developing suitable methodologies for defining 'needs', the impact of local authority policies on improving car-less rural residents accessibility requirements will be minimal.

description: Europäische sowie nationale agrar- und gesellschaftspolitische Weiterentwicklungsmaßnahmen des Kulturpflanzenanbaus zielen verstärkt auf zunehmende Extensivierungen ab, um den Umwelt- und Naturschutz sowie den Klimaschutz zu fördern. Dabei offenbaren sich zahlreiche Zielkonflikte in der Produktion, Versorgung sowie bei agrarstrukturellen Zielsetzungen, die sich insbesondere in vielfachen Antagonismen zwischen Klima-, Umwelt- und Naturschutz einerseits sowie der Profitabilität der landwirtschaftlichen Produktion andererseits zeigen. Vor diesem Hintergrund werden Optionen der Produktion und Vermarktung zur Inwertsetzung von Ökosystemleistungen aufgezeigt, die viele bislang erkennbare Zielkonflikte zumindest verringern können. Damit könnten die bisherigen, mit Hilfe der Steuerzahler getragenen staatlichen Leistungen durch Leistungen in Form höherer Marktpreise durch Konsumenten ergänzt werden, um ein höheres Niveau an Ökosystemleistungen zu realisieren. Zu diesen Optionen zählen z. B. Produktionsmöglichkeiten im Ackerbau ohne chemischen Pflanzenschutz, aber mit Mineraldüngereinsatz, oder auch (Bio-)Rindermastsysteme auf Basis der Weidehaltung mit regionalem Vermarktungscharakter. Viele dieser Produktionsoptionen sind jedoch kaum flächendeckend umsetzbar und erfordern besondere individuelle oder regionale Rahmenbedingungen.

description: The rising penetration of renewable energies became an important issue in the German electricity sector within the past years. In order to plan the required infrastructure for the energy distribution, a detailed knowledge about the complete geographical and temporal power generation compared to the demand is crucial. However, the available data for the renewable power generation in Germany is insufficient due to the complexity of the energy system. For this reason, a comparison between the renewable power generation and the electricity demand is presented for 95 German zip code regions based on real input data with a sample time of 15 min from renewable energy generators. For enhancing the incomplete data, different model-based data filling methods using the data of neighboured regions or additional meteorological data are introduced and compared. As a result, a number of modelling methods, based either on a heuristic model, a wind speed model or a combination of both, has been investigated, leading to similar correlation coefficients of above 80%. Finally, the obtained data set is applied for an analysis with a high spatiotemporal resolution. For three use cases the resulting optimal flow of the inter-regional power transfers is calculated.

description: The aim of the present paper is to study the dynamics of a dumbbell satellite moving in a gravity field generated by an oblate body considering the effect of the zonal harmonic parameter. We prove that the pass trajectory of the mass center of the system is periodic and different from the classical one when the effect of the zonal harmonic parameter is non zero. Moreover, we complete the classical theory show- ing that the equations of motion in the satellite approximation can be reduced to Beletsky's equation when the zonal harmonic parameter is zero. The main tool for proving these results is the Lindstedt{Poincare's technique.

description: Weak localization and weak anti-localization are quantum interference effects in quantum transport in a disordered electron system. Weak anti-localization enhances the conductivity and weak localization suppresses the conductivity with decreasing temperature at very low temperatures. A magnetic field can destroy the quantum interference effect, giving rise to a cusp-like positive and negative magnetoconductivity as the signatures of weak localization and weak anti-localization, respectively. These effects have been widely observed in topological insulators. In this article, we review recent progresses in both theory and experiment of weak (anti-)localization in topological insulators, where the quasiparticles are described as Dirac fermions. We predicted a crossover from weak anti-localization to weak localization if the massless Dirac fermions (such as the surface states of topological insulator) acquire a Dirac mass, which was confirmed experimentally. The bulk states in a topological insulator thin film can exhibit the weak localization effect, quite different from other system with strong spin-orbit interaction. We compare the localization behaviors of Dirac fermions with conventional electron systems in the presence of disorders of different symmetries. Finally, we show that both the interaction and quantum interference are required to account for the experimentally observed temperature and magnetic field dependence of the conductivity at low temperatures.

We use wavepacket propagation to study its single-mode dynamics, which also determines its multimode current for mesoscopic setups. Energy flow with or without particle transport is possible. The spectrum reveals unusual features such as nonuniform Floquet side-bands and counter-intuitive scattering. Explanations are found by examining the scattering dynamics comparatively using quantum, classical and semiclassical pictures, indicating a rich system and experimentally accessible method to explore quantum versus classical dynamics.

description: The \"Cooperative Action Leading to Launcher Innovation in Stage Toss back Operations\" (CALLISTO) is a cooperative project between DLR, JAXA and CNES for the research and development of reusable launch vehicle relevant technologies. Its goal is the development of a vertical take-off and vertical landing reusable subscale first stage demonstrator. The mission of the CALLISTO vehicle is to return to the launch pad using retro-propulsion and an Approach and Landing System (ALS) with deployable landing legs. This development leads to additional aerodynamic and aerothermal design questions compared to traditional launchers. An aerodynamic and an aerothermal database have been created to provide the relevant loads to system and product engineering teams. Since the creation of these databases the design process of the Callisto vehicle has matured and a new geometric shape of the vehicle has been designed. In this work we analyse the differences in aerodynamic and aerothermal loads between the geometries for two descent configurations. The simulations are done using Reynolds averaged Naiver Stokes methods with a Spalart-Allmaras turbulence model and frozen chemistry. We analyse the flow field as well as the surface distributions of coefficients and heat fluxes.

description: Die Landwirtschaft ist durch die Gemeinsame Agrarpolitik geprägt, welche die Sicherung der Einkommen der Landwirte mehr fördert als den Umwelt- und Naturschutz. So besteht zwischen der Produktivität und der nachhaltigen Nutzung der natürlichen Ressourcen ein Zielkonflikt. Eher extensive Landnutzungen wie der Ökolandbau können lokale Umwelt- und Naturschutz-Defizite beheben, verursachen aber aufgrund niedrigerer Erträge steigende Importe von Lebensmitteln und damit unerwünschte Verlagerungen von Umwelteffekten. Eine diversifizierte Produktion in einer vielfältigen Landschaft, die weniger restriktiv bezüglich Betriebsmittel ist und stärker auf nachhaltige Wirkung schaut, könnte diese Zielkonflikte vermindern. Nimmt man Vielfalt als Zielgröße, verändert das auch die Richtung der Agrarforschung. Dank der modernen, digital gesteuerten Landtechnik steht der Diversifizierung von Agrarlandschaften, Betrieben, Feldern und Fruchtfolgen nichts mehr im Wege. Der Einsatz von Herbiziden, Pflanzenschutzmitteln und Düngern kann ohne Ertragseinbußen gesenkt werden. Mischkulturen und agroforstähnlichen Anbausysteme werden arbeitstechnisch möglich. Solche diversifizierten Systeme haben eine höhere Land Equivalent Ratio (LER), was auf gleicher Fläche zu einer besseren Nutzung von Licht, Wärme, Wasser und Nährstoffen führt. Konsequente Vielfalt könnte die Produktionsform der Zukunft ausmachen.

description: The influence of inhomogeneous refractive index fields on particle image velocimetry (PIV) measurements is a well known problem, which leads to an unknown measurement uncertainty in, e.g., flame flows, shock waves and super sonic flows. Previous studies give only rough estimations of the measurement error due to inhomogeneous refractive index fields, and quantitative information is only available for special conditions such as a gradient of the refractive index independent of the viewing direction. Hence, the assessment of the spatial distribution of the quantitative measurement errors inside inhomogeneous refractive index distributions especially for stereoscopic and tomographic PIV is an open question. For this purpose, the flow measurement inside a hot jet flow is considered as an example, and a general analytic description of the error of the measured particle positions inside the hot jet flow is derived, numerically evaluated and finally validated by experiments. In particular, the determination of the particle position with triangulation is investigated, which is performed in stereoscopic and tomographic PIV. As a result, the measurement error is generally larger than for standard PIV without triangulation. The theoretically predicted errors of the measured particle position are validated with experiments and here amount to 11.7 µm for standard PIV and 17.3 µm for triangulation at the same distance from the center of the flow, respectively. Note that the error estimation requires the knowledge of the refractive index field that was determined by temperature measurements in the flow. Furthermore, the error analysis shows that for triangulation the measured particle position depends on the gradient and the curvature of the refractive index field, whereas for standard PIV the measured particle position only depends on the gradient of the refractive index. For the given temperature profile with a maximum temperature of 191 °C, the resulting flow velocity error is maximally 0.8 % with standard PIV, 1.7 % for the in plane and 2.9 % for the out of plane direction with stereoscopic PIV and 1.1 % with triangulation which is performed in tomographic PIV.

An extensive discussion is provided on the algorithm choice and construction, considering security factors, user experience, and the interest of various stakeholders. The project also develops an implementation in Golang expanding the existing go-crypto library, to ensure that the proposed standard can be cleanly implemented, and to measure the actual performance on real desktop and mobile devices. The performance data is then carefully analyzed to provide insights on the expected differences in user experience and the necessary changes to the OpenPGP applications.

description: BackgroundAlthough engineered nanomaterials (ENM) are currently regulated either in the context of a new chemical, or as a new use of an existing chemical, hazard assessment is still to a large extent reliant on information from historical toxicity studies of the parent compound, and may not take into account special properties related to the small size and high surface area of ENM. While it is important to properly screen and predict the potential toxicity of ENM, there is also concern that current toxicity tests will require even heavier use of experimental animals, and reliable alternatives should be developed and validated. Here we assessed the comparative respiratory toxicity of ENM in three different methods which employed in vivo, in vitro and ex vivo toxicity testing approaches.MethodsToxicity of five ENM (SiO2 (10), CeO2 (23), CeO2 (88), TiO2 (10), and TiO2 (200); parentheses indicate average ENM diameter in nm) were tested in this study. CD-1 mice were exposed to the ENM by oropharyngeal aspiration at a dose of 100μg. Mouse lung tissue slices and alveolar macrophages were also exposed to the ENM at concentrations of 22–132 and 3.1-100μg/mL, respectively. Biomarkers of lung injury and inflammation were assessed at 4 and/or 24hr post-exposure.ResultsSmall-sized ENM (SiO2 (10), CeO2 (23), but not TiO2 (10)) significantly elicited pro-inflammatory responses in mice (in vivo), suggesting that the observed toxicity in the lungs was dependent on size and chemical composition. Similarly, SiO2 (10) and/or CeO2 (23) were also more toxic in the lung tissue slices (ex vivo) and alveolar macrophages (in vitro) compared to other ENM. A similar pattern of inflammatory response (e.g., interleukin-6) was observed in both ex vivo and in vitro when a dose metric based on cell surface area (μg/cm2), but not culture medium volume (μg/mL) was employed.ConclusionExposure to ENM induced acute lung inflammatory effects in a size- and chemical composition-dependent manner. The cell culture and lung slice techniques provided similar profiles of effect and help bridge the gap in our understanding of in vivo, ex vivo, and in vitro toxicity outcomes.Electronic supplementary materialThe online version of this article (doi:10.1186/s12951-014-0047-3) contains supplementary material, which is available to authorized users.
