description: This paper presents a knowledge-based detection of objects approach using the OWL ontology language, the Semantic Web Rule Language, and 3D processing built-ins aiming at combining geometrical analysis of 3D point clouds and specialist's knowledge. Here, we share our experience regarding the creation of 3D semantic facility model out of unorganized 3D point clouds. Thus, a knowledge-based detection approach of objects using the OWL ontology language is presented. This knowledge is used to define SWRL detection rules. In addition, the combination of 3D processing built-ins and topological Built-Ins in SWRL rules allows a more flexible and intelligent detection, and the annotation of objects contained in 3D point clouds. The created WiDOP prototype takes a set of 3D point clouds as input, and produces as output a populated ontology corresponding to an indexed scene visualized within VRML language. The context of the study is the detection of railway objects materialized within the Deutsche Bahn scene such as signals, technical cupboards, electric poles, etc. Thus, the resulting enriched and populated ontology, that contains the annotations of objects in the point clouds, is used to feed a GIS system or an IFC file for architecture purposes.

description: В современных условиях интенсификации сельского хозяйства остро встает вопрос о со-единении его отраслей. Качественной, а главное, безопасной продукции отечественного производства в настоящее время недостаточно для удовлетворения потребностей быст-рорастущего населения. Поэтому развитие направления аквапоники – совместного выра-щивания рыбы и растений весьма актуально, особенно в условиях Краснодарского края, который располагает всеми ресурсами для успешного ведения сельского хозяйства.

description: We study forward neutrino-induced meson production off the nucleon in the resonance region. Our calculation is based on a dynamical coupled-channels (DCC) model that reasonably describes pi (gamma) N -> pi N, eta N, K Lambda, K Sigma data in the resonance region. We apply the PCAC hypothesis to the DCC model to relate the pi N reaction amplitude to the forward neutrino reaction amplitude. In this way, we give a prediction for nu N -> pi N, pi pi N, eta N, K Lambda, K Sigma reaction cross sections. The predicted nu N -> pi pi N, eta N, K Lambda, K Sigma cross sections are, for the first time, based on a model extensively tested by data. We compare our results with those from the Rein-Sehgal model that has been very often used in the existing Monte Carlo simulators for neutrino experiments. We find a significant difference between them.

description: We address binary optical communication channels based on phase-shift keyed coherent signals in the presence of phase diffusion. We prove theoretically and demonstrate experimentally that a discrimination strategy based on homodyne detection is robust against this kind of noise for any value of the channel energy. Moreover, we find that homodyne receiver beats the performance of Kennedy receiver as the signal energy increases, and achieves the Helstrom bound in the limit of large noise.

description: Since the late 90s the use of zirconia based all-ceramic restorations increases. Many manufacturing steps are necessary, like pre-sintering, soft machining (pre-sintered condition), sintering and hard machining (fully sintered) in combination with a final staining or veneering step. All these techniques, especially hard machining, are associated with the production of flaws in different scales, in conjunction with thermal and residual stresses and phase transformations. These are inter alia capable to induce failure. This work investigates the impact of hard machining on the material properties and attempts to establish a correlation to failure. © 2016 Published by Elsevier B.V.

description: Sales revenues of small and medium-sized enterprises are subject to seasonal fluctuation. This leads often to overloaded or underutilized manufacturing resources. Either way, this results in revenue losses. Therefore, companies have to optimize their resource utilization. This paper describes a new methodology for a dynamic bid price system by using correlations of revenue management in production planning to level the resource utilization. The methodology supports especially small and medium-sized enterprises, which are often affected by additional work shifts across seasons. Furthermore, the proposed method points out dependencies between costs and capacity to avoid financial losses. The method has been developed and is being tested in collaboration with two small and medium-sized enterprises. © 2017 The Authors.

From 9-IM Topological Operators to Qualitative Spatial Relations using 3D Selective Nef Complexes and Logic Rules for bodies

description: This paper presents a method to compute automatically topological relations using SWRL rules. The calculation of these rules is based on the definition of a Selective Nef Complexes Nef Polyhedra structure generated from standard Polyhedron. The Selective Nef Complexes is a data model providing a set of binary Boolean operators such as Union, Difference, Intersection and Symmetric difference, and unary operators such as Interior, Closure and Boundary. In this work, these operators are used to compute topological relations between objects defined by the constraints of the 9 Intersection Model (9-IM) from Egenhofer. With the help of these constraints, we defined a procedure to compute the topological relations on Nef polyhedra. These topological relationships are Disjoint, Meets, Contains, Inside, Covers, CoveredBy, Equals and Overlaps, and defined in a top-level ontology with a specific semantic definition on relation such as Transitive, Symmetric, Asymmetric, Functional, Reflexive, and Irreflexive. The results of the computation of topological relationships are stored in an OWL-DL ontology allowing after what to infer on these new relationships between objects. In addition, logic rules based on the Semantic Web Rule Language allows the definition of logic programs that define which topological relationships have to be computed on which kind of objects with specific attributes. For instance, a "Building" that overlaps a "Railway" is a "RailStation".

Luminosities of Carbon-rich Asymptotic Giant Branch stars in the Milky Way

Year: 2013
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Stars evolving along the Asymptotic Giant Branch can become Carbon-rich in the final part of their evolution. They replenish the inter-stellar medium with nuclear processed material via strong radiative stellar winds. The determination of the luminosity function of these stars, even if far from being conclusive, is extremely important to test the reliability of theoretical models. In particular, strong constraints on the mixing treatment and the mass-loss rate can be derived. We present an updated Luminosity Function of Galactic Carbon Stars obtained from a re-analysis of available data already published in previous papers. Starting from available near- and mid-infrared photometric data, we re-determine the selection criteria. Moreover, we take advantage from updated distance estimates and Period-Luminosity relations and we adopt a new formulation for the computation of Bolometric Corrections. This leads us to collect an improved sample of carbon-rich sources from which we construct an updated Luminosity Function. The Luminosity Function of Galactic Carbon Stars peaks at magnitudes around -4.9, confirming the results obtained in a previous work. Nevertheless, the Luminosity Function presents two symmetrical tails instead of the larger high luminosity tail characterizing the former Luminosity Function. The derived Luminosity Function of Galactic Carbon Stars matches the indications coming from recent theoretical evolutionary Asymptotic Giant Branch models, thus confirming the validity of the choices of mixing treatment and mass-loss history. Moreover, we compare our new Luminosity Function with its counterpart in the Large Magellanic Cloud finding that the two distributions are very similar for dust-enshrouded sources, as expected from stellar evolutionary models. Finally, we derive a new fitting formula aimed to better determine Bolometric Corrections for C-stars.

description: We present Herschel/HIFI observations of 30 transitions of water isotopologues toward the high-mass star forming region NGC 6334 I. The line profiles of H_2^{16}O, H_2^{17}O, H_2^{18}O, and HDO show a complex pattern of emission and absorption components associated with the embedded hot cores, a lower-density envelope, two outflow components, and several foreground clouds, some associated with the NGC 6334 complex, others seen in projection against the strong continuum background of the source. Our analysis reveals an H2O ortho/para ratio of 3 +/- 0.5 in the foreground clouds, as well as the outflow. The water abundance varies from ~10^{-8} in the foreground clouds and the outer envelope to ~10^{-6} in the hot core. The hot core abundance is two orders of magnitude below the chemical model predictions for dense, warm gas, but within the range of values found in other Herschel/HIFI studies of hot cores and hot corinos. This may be related to the relatively low gas and dust temperature (~100 K), or time dependent effects, resulting in a significant fraction of water molecules still locked up in dust grain mantles. The HDO/H_2O ratio in NGC 6334 I, ~2 10^{-4}, is also relatively low, but within the range found in other high-mass star forming regions.

description: Der Artikel beschäftigt sich mit ursprünglich babylonischen Typifizierungen „verderbter“ Könige, die sich gegen den Gott Marduk und seine heilige Stadt Babylon stellen. Dieser Typus wandert später in die biblische und frühislamische Literatur. Die Überlegungen schlagen einen Bogen von der Ermordung des assyrischen Königs Sanherib, hinweg über die berühmte Sentenz al-Bīrūnīs, daß „die Einwohner Jerusalems anscheinend jeden, der ihre Stadt zerstört, einen Nebukadnezar heißen“, bis hin zur Ermordung des letzten Sassanidenherrschers Khosrau II., welcher als bisher letzter Wiedergänger Sanheribs auf der Bühne der Weltgeschichte auf- und von ihr abgetreten ist. سنخ شناسی "شاه فاسد" در منابع شرقی باستان هانس پتر شاودیگ این مقاله به بررسی سنخ شناسی شاه "فاسد" در متون بابلی می پردازد. متونی که علیه مردوک و شهر مقدس بابل موضع گرفتند. این تصویر سنخی سپس به عهد عتیق و سپس‌تر به متون آغازین اسلامی منتقل می‌شود. غور در این باب اندیشه‌ی وجود یک خط ممتد را پیش می‌نهد. کمانی که از قتل سنخریب شاه آشوری، تا جمله‌ی معروف ابوریحان بیرونی که گفت "ساکنان اورشلیم، هر کس شهرشان را ویران کند نبوکدنصر می‌نامند"، تا قتل خسرو دوم آخرین پادشاه ساسانی - آخرین سنخریب تاریخ – کشیده می‌شود. امیدوارم این مقاله که برای چاپ در جشن‌نامه‌ی آقای پروفسون نجم‌آبادی تنظیم شده، مورد توجه ایشان واقع گردد.

description: Modern DNA sequencing technologies enable geneticists to rapidly identify genetic variation among many human genomes. However, isolating the minority of variants underlying disease remains an important, yet formidable challenge for medical genetics. We have developed GEMINI (GEnome MINIng), a flexible software package for exploring all forms of human genetic variation. Unlike existing tools, GEMINI integrates genetic variation with a diverse and flexible set of genome annotations (e.g., dbSNP, ENCODE, UCSC, ClinVar, KEGG) into a unified database to facilitate interpretation and data exploration. Whereas other methods provide an inflexible set of variant filters or variant prioritization methods, GEMINI allows researchers to compose complex queries based on sample genotypes, inheritance patterns, and both pre-installed and custom genome annotations. GEMINI also provides methods for ad hoc queries and data exploration, a simple programming interface for custom analyses that leverage the underlying database, and both command line and graphical tools for common analyses. We demonstrate the utility of GEMINI for exploring variation in personal genomes and family based genetic studies, and illustrate its ability to scale to studies involving thousands of human samples. GEMINI is designed for reproducibility and flexibility and our goal is to will provide researchers with a standard framework for medical genomics.

description: This text examines the gender gap in primary school enrollment in Pakistan. Despite government efforts, girls' enrollment remains lower due to factors such as conservative norms, safety concerns, and the perceived cost of travel. Research shows that distance plays a significant role. Low-cost private schools, with female teachers, offer a more accessible option. Ongoing research aims to reduce the gender gap in enrollment through policy interventions.

description: The high thermo-mechanical tool load during cutting of hard-to-cut material leads to an increased tool wear, which affects the surface integrity and tool life adversely. An innovative approach to counter the wear is to retract the tools flank face at a certain distance from the cutting edge. The so-called flank face modification geometrically limits the tool wear and increases the available material of the tool, which can be removed by the abrasive cutting process until a certain tool life criterion is reached. However, the flank face modification weakens the mechanical stability of the cutting edge. To avoid tool breakage due to excessive mechanical stress, this paper presents a new design approach based on static finite element simulations. Finally, experimental results show an increase in tool life up to 75% compared to conventional tools with these designed modifications.

description: The machining process affects quality and function of components. For this reason, it is an important key competence of the manufacturer. Over the past years, counterfeit products have been threatening the user and damaged the reputation of the original manufacturer. On this account, a method of fingerprinting of ground surfaces was developed in the Collaborative Research Center 653 to protect components against plagiarism. However, this method needs the measuring of every single ground surface, which means a huge expenditure of time in the production chain. If it were possible to predict the grinding surface of the grinding tool precisely, occasional measurements of the grinding tool during the setup time would be sufficient to assign the right tool to the component‘s surface and the manufacturer behind it. The presented paper is focusing on methods for the determination of the topography of grinding tools. These topographies enable the manufacturer to predict and thus identify the surface of components.

description: We present a new sample of mid L to mid T dwarfs with effective temperatures of 1100 to 1700K selected from the UKIDSS Large Area Survey and confirmed with infrared spectra from X-Shooter/VLT. This effective temperature range is especially sensitive to the formation history of Galactic brown dwarfs and allows us to constrain the form of the sub-stellar birth rate, with sensitivity to differentiate between a flat (stellar like) birth rate, and an exponentially declining form. We present the discovery of 63 new L and T dwarfs from the UKIDSS LAS DR7, including the identification of 12 likely unresolved binaries, which form the first complete sub-set from our program, covering 495 sq degrees of sky, complete to J=18.1. We compare our results for this sub-sample with simulations of differing birth rates for objects of mass 0.10-0.03Msol and ages 1-10Gyrs. We find that the more extreme birth rates (e.g. a halo type form) can likely be excluded as the true form of the birth rate. In addition we find that although there is substantial scatter we find a preference for a mass function, with a power-law index, alpha in the range -1 < alpha < 0 that is consistent (within the errors) with the studies of late T dwarfs.

A synthesis of 10 empirical studies across India, Indonesia, Nigeria, and Pakistan highlights challenges such as interlinked incentives, isomorphic mimicry in school-based management, and limited community influence. The studies show the potential for locally developed teaching methods and leveraging local capacity. Debates on education provision, curriculum values, and measurement of learning need to be reopened. Expensive randomized controlled trials have limitations in contexts lacking basic education inputs.

Modulation of electron carrier density at the n-type LaAlO3/SrTiO3 interface by water adsorption

description: We investigate energetic stability and dissociation dynamics of water adsorption at the LaAlO3 surface of the n-type LaAlO3/SrTiO3 (LAO/STO) interface and its effect on electronic properties of the interface by carrying out first-principles electronic structure calculations. In an ambient atmosphere at room temperature the configuration of 1 monolayer (ML) of water molecules including 3/4 ML of dissociated water molecules adsorbed at the surface is found to be most stable, the configuration of 1 ML of dissociated water molecules is metastable. Water molecule dissociation induces a shift-up of the valence band maximum (VBM) of the LAO surface, reducing the gap between the VBM of the LAO surface and the conduction band minimum of the STO. For the LAO/STO interface with three LAO unit-cell layers, once the coverage of dissociated water molecules reaches 1/2 ML the gap is closed, the interface becomes metallic and the carrier density at the LAO/STO interface increases with increasing the coverage of dissociated water molecules. Our findings suggest two ways to control the conductivity at the LAO/STO interface: (I) insulator-metal transition by adsorbing a mount of water at the bare surface; (II) carrier density change by the transition between the most stable and the metastable adsorption configurations for 1 ML coverage in an ambient atmosphere at room temperature.

description: This contribution presents a novel design concept of a 24 GHz radio frequency communication module. The integration of optical and electrical components is a particular challenge since the module is miniaturized in order to be integrated into any metallic workpieces. The design concept and the scope of functions of the communication unit acting as a wireless sensor node are discussed. The development of a highly integrated radio frequency circuit and the realization of through glass vias are some main aspects. The central control unit is an ultra-low power microcontroller capable of a flexible connection of sensors. By using an energy harvesting concept consisting of a solar cell with an efficiency of 40% and a supercapacitor the availability of energy is unlimited. Different lighting conditions are investigated in order to evaluate the available power of the solar cell. Furthermore, the power supply is investigated concerning voltage-current characteristics and the resulting operating time of the whole unit for a low ambient light scenario.

description: Carrier selective junctions formed by polycrystalline silicon (poly-Si) on ultra-thin silicon oxide films are currently in the spotlight of silicon photovoltaics. We develop a simple method using selective etching and conventional optical microscopy to determine the pinhole density in interfacial oxide films of poly-Si on oxide (POLO)-junctions with excellent electrical properties. We characterize the selective etching of poly-Si versus ultra-thin silicon oxide. We use test structures with deliberately patterned openings and 3 nm thin oxide films to check the feasibility of magnification by undercutting the interfacial oxide. With the successful proof of our concept we introduce a new method to access the density of nanometer-size pinholes in POLO-junctions with excellent passivation properties.
Ionized absorbers as evidence for supernova-driven cooling of the lower Galactic corona

description: We show that the ultraviolet absorption features, newly discovered in HST spectra, are consistent with being formed in a layer that extends a few kpc above the disk of the Milky Way. In this interface between the disk and the Galactic corona, high-metallicity gas ejected from the disk by supernova feedback can mix efficiently with the virial-temperature coronal material. The mixing process triggers the cooling of the lower corona down to temperatures encompassing the characteristic range of the observed absorption features, producing a net supernova-driven gas accretion onto the disk at a rate of a few Msun/yr. We speculate that this mechanism explains how the hot-mode of cosmological accretion feeds star formation in galactic disks.

description: Cyber-physical systems are found in many areas, e.g., manufacturing or smart cities. They consist of multiple components that cooperate to provide the desired functionality. This need for cooperation causes complex interactions between components, which makes developing cyber-physical systems difficult, especially systems whose component structure changes dynamically at runtime. We have created a formal, scenario-based specification method which makes it easier to develop distributed cyber-physical systems. We previously presented an approach for the distributed execution of such specifications based on naive and inefficient broadcasting. In this paper we propose a more efficient approach which uses the available network resources more economically.

An asymmetry between pushing and pulling for crawling cells

description: Eukaryotic cells possess motility mechanisms allowing them not only to self-propel but also to exert forces on obstacles (to push) and to carry cargoes (to pull). To study the inherent asymmetry between active pushing and pulling we model a crawling acto-myosin cell extract as a 1D layer of active gel subjected to external forces. We show that pushing is controlled by protrusion and that the macroscopic signature of the protrusion dominated motility mechanism is concavity of the force velocity relation. Instead, pulling is driven by protrusion only at small values of the pulling force and it is replaced by contraction when the pulling force is sufficiently large. This leads to more complex convex-concave structure of the force velocity relation, in particular, competition between protrusion and contraction can produce negative mobility in a biologically relevant range. The model illustrates active readjustment of the force generating machinery in response to changes in the dipole structure of external forces. The possibility of switching between complementary active mechanisms implies that if necessary 'pushers' can replace 'pullers' and visa versa.

description: To ensure productivity and product quality, the parameters of biotechnological processes need to be monitored. Along temperature or pH, one important parameter is the cell density in the culture medium. In this work, we present a low-cost sensor system for online cell growth monitoring in bioreactors via permittivity measurements based on coplanar transmission lines. To evaluate the sensor, E. coli cultivations are performed. We found a good correlation between optical density of the culture medium and the effective permittivity at a frequency of 1 kHz when the sensor is submerged into the culture medium. Measurements at higher frequencies additionally allow monitoring the osmolarity. Furthermore, an improved sensor was successfully used for first noninvasive measurements through the polymer wall of a disposable bioreactor.

description: Auf den Punkt ...
Das deutsche ‚Beschäftigungswunder‘ ist mit einer Zunahme von Prekaritätsrisiken einhergegangen. Atypisch Beschäftigte sind davon zwar stärker betroffen, die Arbeitsstandards für Normalarbeitnehmer/innen sind jedoch ebenfalls unter Druck geraten.

Es ist umstritten, ob Akteure und Prozess des sozialen Dialogs eher zur Entstehung und Stabilisierung der Arbeitsmarktspaltung beitragen oder ihr entgegenwirken. Ausgewählte Fallstudien dokumentieren die Schwierigkeiten, die sich dabei stellen, selbst wenn es nur um die Durchsetzung von Mindeststandards geht. Sie illustrieren zugleich, dass eine Verringerung der Arbeitsmarktspaltung möglich ist, und zwar gerade dort, wo Ressourcen und Verfahren des sozialen Dialogs noch vergleichsweise gut erhalten sind.

Weiterhin bedarf es jedoch eines stärkeren ‚Schattens der Hierarchie‘ bzw. auch direkter gesetzlicher Eingriffe, um inklusivere Unternehmensstrategien zu ‚fordern und fördern‘. Der gesetzliche Rahmen bietet bislang unzureichenden Schutz für neue und alte Gefährdungslagen.

Die Orientierung der Gesetzgebung am Gleichstellungsprinzip (equal pay/equal treatment) greift außerdem zu kurz, wenn es sich faktisch auf Mindeststandards beschränkt und zudem die spezifischen Risiken atypischer Beschäftigung nicht berücksichtigt. Zudem erfordert die wirksame Durchsetzung von Gleichstellung, dass die Nutzung atypischer Beschäftigung in einem überschaubaren und kontrollierbaren Rahmen gehalten wird.

description: Cyber-physical systems can be found in many areas, e.g., manufacturing, health care or smart cities. They consist of many distributed components cooperating to provide increasingly complex functionality. The design and development of such a system is difficult and error-prone. To help engineers overcome these challenges we created a formal, scenario-based specification language. Short scenarios, i.e., event sequences, specify requirements and the desired behaviors by describing how components may, must, or must not behave. Scenarios provide an intuitive way for creating formal assume-guarantee (GR(1)) specifications, giving engineers easy access to simulation, for validating the specified behavior, and controller synthesis, for creating controller software which is correct by construction. In this paper we present an approach for generating Programmable Logic Controller (PLC) code from a scenario-based specification. Previous code generation efforts, including our own, created large, verbose source files causing some tools, e.g., compilers or editors, to perform slowly or even become unresponsive. Our new approach creates compact files, shifting significant amounts of code from executable instructions to data, to reduce the burden on the compiler and other tools. The generated code is efficient and introduces minimal to no latency between the occurrence of an event and the system's reaction to it.

description: A new cyprinid species, Pectenocypris rubra, is described from peat swamps from central Sumatra (Indonesia). This species is only known from peat lakes upstream of the river Serkap, a tributary of the Kampar River. Pectenocypris rubra differs from the other four species of this genus in the following combination of characters: a distinct mid-lateral stripe, an oval black spot at the base of the caudal fin, scales in lateral midline 33, 7 – 8 pored lateral line scales, 202 gill-rakers on first gill arch, small dark grey symphyseal knob on lower jaw, and a long and narrow caudal peduncle.
