description: Der Einfluss des sog. Early-Age-Movement (EAM) – d. h. der durch Wind und Wellengang bedingten zyklischen Relativverschiebung zweier durch Hochleistungsbeton (sog. Grout-Material) zu verbindenden Stahlbauteile von Offshore-Windenergieanlagen – auf die rheologischen Eigenschaften des Grout-Materials ist bislang nur unzureichend erforscht. Ein aktueller Ansatz, der eine Kombination aus rotatorischen und oszillatorischen Scherversuchen darstellt, wurde im Rahmen dieses Beitrages verwendet, um den Einfluss des EAM auf die Rheologie von Grout-Materialien quantitativ zu erfassen. Weiterhin wird der Einfluss aus dem EAM auf die Druckfestigkeit des erhärteten Grout-Materials beschrieben. Es konnte festgestellt werden, dass mit geringerem Wassergehalt ein beschleunigter Anstieg der rheologischen Eigenschaften eintritt. Dies wird auf den geringeren Partikelabstand in der Suspension des Grout-Materials mit geringerem Wassergehalt zurückgeführt. Darüber hinaus tritt mit größerem Oszillationswinkel eine beschleunigte Zunahme der rheologischen Eigenschaften ein, was auf Agglomerations- und Entlüftungsprozesse zurückzuführen ist. Letzteres erhöht die Druckfestigkeit des erhärteten Grout-Materials.
description: The influence of the phenomenon Early-Age-Movement (EAM) on the rheological properties of grout is vastly unexplored so far. A new approach, which represents a combination of rotational and oscillatory shear tests, was used in order to investigate the influence of EAM on the rheology of grout. Furthermore, the influence of EAM on the compressive strength of hardening grouts was investigated. It could be shown that the lower the water content of the grout, the more accelerated an increase in rheological properties is. This was ascribed to the reduced interparticle distance with reduced water content. In addition, a greater oscillation angle leads to an accelerated increase in rheological properties, which is concluded to result by extrinsic agglomeration processes superimposed by a deaeration of the grout. The last effect results in a greater compressive strength of the hardened grout.

description: While existing face recognition systems based on local features are robust to issues such as misalignment, they can exhibit accuracy degradation when comparing images of differing resolutions. This is common in surveillance environments where a gallery of high resolution mugshots is compared to low resolution CCTV probe images, or where the size of a given image is not a reliable indicator of the underlying resolution (eg. poor optics). To alleviate this degradation, we propose a compensation framework which dynamically chooses the most appropriate face recognition system for a given pair of image resolutions. This framework applies a novel resolution detection method which does not rely on the size of the input images, but instead exploits the sensitivity of local features to resolution using a probabilistic multi-region histogram approach. Experiments on a resolution-modified version of the "Labeled Faces in the Wild" dataset show that the proposed resolution detector frontend obtains a 99% average accuracy in selecting the most appropriate face recognition system, resulting in higher overall face discrimination accuracy (across several resolutions) compared to the individual baseline face recognition systems.

description: The Erlang Truncated (ETE) distribution is modified and the new lifetime distribution is called the Extended Erlang Truncated Exponential (EETE) distribution. Some statistical and reliability properties of the new distribution functions have been characterized based on two non-adjacent generalized and dual generalized order statistics. Moreover, we show that these characterization properties provide a beneficial strategy to predict future events, which are based on past or current events and on an arbitrary distribution function. A characterization in statistics is a specific distributional property of a statistic that uniquely identify related parametric family of distributions. In statistical applications, the researchers usually want to verify whether the data that they are dealing with belong to a certain family of DFs. Therefore, the researchers have to rely on a characterization of the assumed distribution and check if the corresponding conditions are satisfied.

description: The inert higgs model is a minimal extension of the Standard Model that features a viable dark matter candidate, the so-called inert higgs ($H^0$). In this paper, we compute and analyze the dominant electroweak corrections to the direct detection cross section of dark matter within this model. These corrections arise from one-loop diagrams mediated by gauge bosons that, contrary to the tree-level result, do not depend on the unknown scalar coupling $λ$. We study in detail these contributions and show that they can modify in a significant way the prediction of the spin-independent direct detection cross section. In both viable regimes of the model, $\mh

description: In order to qualify residual stress relaxation as an indicator of mechanical overloading of machined parts, an individually designed residual stress profile has to be allocated. Even though numerous investigations have been carried out in the past, residual stress profiles cannot be predicted to a satisfactory degree. For this reason, essential studies on the reproducibility of residual stress profiles for several external cylindrical turning parameters are conducted and it is demonstrated that identical residual stress profiles can be induced successfully. Subsequently, specimens with defined residual stress profiles are loaded in bending tests with various numbers of test cycles. The amount of residual stress relaxation in the specimen's surface layer is measured to determine the influence of theapplied load on the stress relaxation. By applying single tensile and compressive loads below and above thematerial's yield and ultimate strength, the stress relaxation can be evaluated in detail.

The multi-scale model is realized by coupling a mechatronic simulation model implemented in Matlab/Simulink and a transient 2D-CFD model realized with the Finite Element-software Ansys using the Flotran solver. The complex behavior of the fluidic system between two control tasks could be observed. The permission for large movements of the slide is solved using an appropriate remeshing concept.

description: Molecular nitrogen is one of the key species in the chemistry of interstellar clouds and protoplanetary disks and the partitioning of nitrogen between N and N2 controls the formation of more complex prebiotic nitrogen-containing species. The aim of this work is to gain a better understanding of the interstellar N2 photodissociation processes based on recent detailed theoretical and experimental work and to provide accurate rates for use in chemical models. We simulated the full high-resolution line-by-line absorption + dissociation spectrum of N2 over the relevant 912-1000 Å wavelength range, by using a quantum-mechanical model which solves the coupled-channels Schrödinger equation. The simulated N2 spectra were compared with the absorption spectra of H2, H, CO, and dust to compute photodissociation rates in various radiation fields and shielding functions. The effects of the new rates in interstellar cloud models were illustrated for diffuse and translucent clouds, a dense photon dominated region and a protoplanetary disk.

A Generation-based Text Steganography Method using SQL Queries
Creators: name: Bassil, Youssef
Publisher: name: arXiv
Year: 2012
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Cryptography and Steganography are two techniques commonly used to secure and safely transmit digital data. Nevertheless, they do differ in important ways. In fact, cryptography scrambles data so that they become unreadable by eavesdroppers; while, steganography hides the very existence of data so that they can be transferred unnoticed. Basically, steganography is a technique for hiding data such as messages into another form of data such as images. Currently, many types of steganography are in use; however, there is yet no known steganography application for query languages such as SQL. This paper proposes a new steganography method for textual data. It encodes input text messages into SQL carriers made up of SELECT queries. In effect, the output SQL carrier is dynamically generated out of the input message using a dictionary of words implemented as a hash table and organized into 65 categories, each of which represents a particular character in the language. Generally speaking, every character in the message to hide is mapped to a random word from a corresponding category in the dictionary. Eventually, all input characters are transformed into output words which are then put together to form an SQL query. Experiments conducted, showed how the proposed method can operate on real examples proving the theory behind it. As future work, other types of SQL queries are to be researched including INSERT, DELETE, and UPDATE queries, making the SQL carrier quite puzzling for malicious third parties to recuperate the secret message that it encodes.

description: The room temperature spontaneous reduction of HAuCl4 in ethylene glycol in the presence of pre-formed ZnO nanoparticles is investigated by UV-vis spectroscopy. Analysis by HRTEM demonstrated that the synthesized nanostructures consist of small ZnO nanoparticles (5.0 nm) in contact with bigger (15 nm) spherical Au nanoparticles. The electronic communication between Au and ZnO blocks is confirmed by UV excitation of the colloid. These experiments indicate that ZnO nanoparticles efficiently transfer the electrons to Au nanoparticles in contact, inducing a 15 nm blue shift in the plasmon band. Titration experiments using the methylviologen couple (MV2+/MV center dot+) are presented and analyzed to quantify the enhancement in the electron storage capability in the new nanostructure and the negative shift in the Fermi level caused by the Au loading in ZnO.

description: Today’s life is a age of modern life, and in the modern life for any kind of business setup, customer service, pricing, stocking strategies and trade credit financing schemes are effective, essential and survival parameters to grow the business. In this paper, we have developed, an economical order quantity model for imperfect quality product by considering retailer’s stock sensitive demand of product under trade credit financing policy. Further in this paper we have studied the Learning effect on screening process on every batch of imperfect quality product. Under the trade credit financing scheme, we have considered that, the supplier proposes to the retailer, a fixed credit time period for payment and retailer also offers to his customers to a fixed credit time period of payment. Finally an appropriate total profit function per unit time has been derived under the various trade credit financing periods of payment including various expenditure and other related parameters. A sensitivity analysis has been done to verify the optimum results and also a numerical example has been given to verify the model’s outputs.

Comparing the central branch with all other branches, we find that the central branch, among all the avatars of the Wilson fermion, is the most suitable candidate for exploring near conformal lattice field theories.

description: Die Mischungsstabilität von Beton stellt eine wichtige Frischbetoneigenschaft dar, um insbesondere unter herausfordernden Betonierbedingungen eine zielsichere Herstellung von Betonbauteilen sicher-zustellen. Jedoch existiert aktuell kein geeignetes Prüfverfahren, um die Mischungsstabilität im Rahmen des Bauprozesses quantitativ zu erfassen und zu bewerten. Der vorliegende Beitrag zeigt, dass der aus dem Bereich der Selbstverdichtenden Betonen bekannte „Auswaschversuch“ so modifiziert werden kann, dass er auch für übliche Rüttelbetone geeignet ist. Entscheidend hierfür ist die Berücksichtigung und genaue Definition der eingebrachten Rüttel-einwirkung, um eine Reproduzierbarkeit und Vergleichbarkeit der Prüfergebnisse sicher zu stellen. Erste Vergleichsuntersuchungen zeigen, dass mit Hilfe der Prüfergebnisse bei vergleichbarer Rütteleinwirkung auch eine Prognose der Sedimentation im Bauteil möglich ist.
description: The stability of concrete represents an important feature of fresh concrete in order to ensure a targeted production of concrete components, especially under challenging processing conditions. However, there exists currently no suitable test method to test and evaluate the mixing stability of fresh concrete during the construction process. The present article shows that the "washout-test", known from the field of self-compacting concrete, can be transferred to conventional concrete. Decisive for this is the consideration and exact quantification of the vibrations introduced during the test and ensuring a reproducibility and comparability of the test results. Initial comparative investigations between construction components and results of the test method show that with comparable vibration a forecast from test results to sedimentation in the component is also possible.
Dynamical barriers of pure and random ferromagnetic Ising models on fractal lattices

description: We consider the stochastic dynamics of the pure and random ferromagnetic Ising model on the hierarchical diamond lattice of branching ratio $K$ with fractal dimension $d_f=(\ln (2K))/\ln 2$. We adapt the Real Space Renormalization procedure introduced in our previous work [C. Monthus and T. Garel, J. Stat. Mech. P02037 (2013)] to study the equilibrium time $t_{eq}(L)$ as a function of the system size $L$ near zero-temperature. For the pure Ising model, we obtain the behavior $t_{eq}(L) \sim L^α e^{β2J L^{d_s}} $ where $d_s=d_f-1$ is the interface dimension, and we compute the prefactor exponent $α$. For the random ferromagnetic Ising model, we derive the renormalization rules for dynamical barriers $B_{eq}(L) \equiv (\ln t_{eq}/β)$ near zero temperature. For the fractal dimension $d_f=2$, we obtain that the dynamical barrier scales as $ B_{eq}(L)= c L+L^{1/2} u$ where $u$ is a Gaussian random variable of non-zero-mean. While the non-random term scaling as $L$ corresponds to the energy-cost of the creation of a system-size domain-wall, the fluctuation part scaling as $L^{1/2}$ characterizes the barriers for the motion of the system-size domain-wall after its creation. This scaling corresponds to the dynamical exponent $ψ=1/2$, in agreement with the conjecture $ψ=d_s/2$ proposed in [C. Monthus and T. Garel, J. Phys. A 41, 115002 (2008)]. In particular, it is clearly different from the droplet exponent $θ\simeq 0.299$ involved in the statics of the random ferromagnet on the same lattice.

description: Constrained Willmore surfaces are critical points of the Willmore functional under conformal variations. As shown in [5] one can associate to any conformally immersed constrained Willmore torus f a compact Riemann surface Σ, such that f can be reconstructed in terms of algebraic data on Σ. Particularly interesting examples of constrained Willmore tori are the tori with constant mean curvature (CMC) in a 3-dimensional space form. It is shown in [14] and in [16] that the spectral curves of these tori are hyperelliptic. In this paper we show under mild conditions that a constrained Willmore torus f in the 3-sphere is a CMC torus in a 3-dimensional space form if its spectral curve has the structure of a CMC spectral curve.

description: Tribodiagnostics deals with the problems of lubrication, friction and analysis of oils in technical fluids. Based on the results of parameter monitoring and chemical analysis of the oil, it is possible to determine the impending failure of the entire system very accurately. Today, this relatively young field of technical diagnostics is gradually becoming very viable and its results are fully in line with classical vibroacoustic diagnostics or thermodiagnostics. It is used in all mechanical systems containing oil systems. This is one of the methods of non-disassembly technical diagnostics, which is based on the knowledge that the lubricant after a certain period of use in the lubrication system reflects the condition of the equipment and the conditions in which this equipment was operated.

description: In this work, luminescent CdSe@CdS dot-in-rod nanocrystals, CdSe@CdS/ZnS nanorods as well as CdSe–CdS core–crown nanoplatelets were transferred into aqueous phase via ligand exchange reactions. For this purpose, bifunctional thiol-based ligands were employed, namely mercaptoacetic acid (MAA), 3-mercaptopropionic acid (MPA), 11-mercaptoundecanoic acid (MUA) as well as 2-(dimethylamino)ethanthiol (DMAET). Systematic investigations by means of photoluminescence quantum yield measurements as well as photoluminescence decay measurements have shown that the luminescence properties of the transferred nanostructures are affected by hole traps (induced by the thiol ligands themselves) as well as by spatial insulation and passivation against the environment. The influence of the tips of the nanorods on the luminescence is, however, insignificant. Accordingly, different ligands yield optimum results for different nanoparticle samples, mainly depending on the inorganic passivation of the respective samples. In case of CdSe@CdS nanorods, the highest emission intensities have been obtained by using short-chain ligands for the transfer preserving more than 50% of the pristine quantum yield of the hydrophobic nanorods. As opposed to this, the best possible quantum efficiency for the CdSe@CdS/ZnS nanorods has been achieved via MUA. The gained knowledge could be applied to transfer for the first time 2-dimensional CdSe–CdS core–crown nanoplatelets into water while preserving significant photoluminescence (up to 12% quantum efficiency).

description: Beton ist der weltweit meist verwendete Baustoff und eines der meist produzierten Güter überhaupt. Seine Produktion in solch großen Mengen erfolgt jedoch unter erheblichen Eingriffen in die natürliche Umwelt, die sowohl signifikante Beiträge zu den anthropogenen CO2-Emissionen wie auch regionale Verknappungen der mineralischen Betonausgangsstoffe beinhalten. Ökobetone müssen sowohl eine verbesserte CO2-Bilanz aufweisen wie auch gegenüber Schwankungen in der Qualität ihrer Ausgangsstoffe robust sein, das heißt die für sie bestimmten Frisch- und Festbetoneigenschaften mit hoher Sicherheiz erzielen. Die granulometrischen Eigenschaften der Ausgangsstoffe und die Zusammensetzung der Gesteinskörnungen spielen hierfür eine zentrale Rolle. Dieser Beitrag erläutert Ansätze zur Entwicklung rheologisch robuster Ökobetone.
description: Concrete is the most used construction material and one of the most produced goods of all. Its production in such large quantities causes great environmental impacts, including significant contributions to anthropogenic CO2-emissions and a decrease in the regional availability of high quality constituent materials. Green concretes must demonstrate an improved CO2-balance over their lifecycle and yet also be robust against variations in the quality of their constituent materials, meaning the desired properties of the concretes must be achieved with a high level of certainty. The granulometric properties of the aggregates are central to this challenge. This paper explains development procedures for rheologically robust concrete mixtures.

description: Leibniz entertained various conceptions of infinitesimals, considering them sometimes as ideal things and other times as fictions. But in both cases, he compares infinitesimals favorably to imaginary roots. We agree with the majority of commentators that Leibniz's infinitesimals are fictions rather than ideal things. However, we dispute their opinion that Leibniz's infinitesimals are best understood as logical fictions, eliminable by paraphrase. This so-called syncategorematic conception of infinitesimals is present in Leibniz's texts, but there is an alternative, formalist account of infinitesimals there too. We argue that the formalist account makes better sense of the analogy with imaginary roots and fits better with Leibniz's deepest philosophical convictions. The formalist conception supports the claim of Robinson and others that the philosophical foundations of nonstandard analysis and Leibniz's calculus are cut from the same cloth.

description: This study proposes and investigates the weighted intervened exponential distribution, which is demonstrated as a generalized extension of the intervened exponential distribution. The form of the weighted intervened exponential distribution is obtained by considering a specific non-negative weighted function. The probability density function and cumulative density function of the proposed model are given, and its generalized form of reliability function and the hazard rate function is also derived. By choosing a different set of parametric values, the graphical demonstrations of the probability density function of weighted intervened exponential distribution are given where it acquires different curve shapes. The weighted intervened exponential distribution density function is then further studied in the limited form as a special case called the length-biased intervened exponential distribution. Along with the distribution of order statistics, stochastic ordering, stress-strength reliability, and entropy measure, several distributional and reliability aspects of the length-biased intervened exponential distribution are derived. For estimating the unidentified parameters of the length-biased variant, the most suggested approach known as the maximum likelihood estimation technique is implemented. To explore the behavior of the parameter estimates for various sample sizes, a sample data generation technique is required to carry out the process. Since the quantile function of the length biased intervened exponential distribution is not in closed form. So, the alternative data generation algorithm is employed which is known as the acceptance-rejection algorithm technique, and a Monte-Carlo simulation study is done. The absolute average bias and mean square error of the estimated parameters of the length-biased version model are calculated and it is noticed that both the calculated measures decrease simultaneously on increasing the sample size. In order to determine if the model is appropriate, a real-life time-to-event data set is examined as an example, and length biased distribution is juxtaposed with several other common available lifetime distributions for comparison purposes.

description: The adsorption of water and deuterium oxide on TiO2 surfaces was investigated in the dark as well as under UV(A) irradiation using in situ ATR-FTIR spectroscopy under oxygen and oxygen free conditions. Adsorption of H2O–D2O mixtures revealed an isotopic exchange reaction occurring onto the surface of TiO2 in the dark. Under UV(A) irradiation, the amount of both OH and OD groups was found to be increased by the presence of molecular oxygen. Furthermore, the photocatalytic formation of hydroperoxide under oxygenated condition has been recorded utilizing Attenuated Total Reflection Fourier Transformed Infrared (ATR-FTIR) spectroscopy which appeared as new band at 3483 cm−1. Different possible mechanisms are discussed in terms of the source of hydroxyl groups formed and/or hydration water on the TiO2 surface for the photocatalytic reaction and photoinduced hydrophilicity.

description: Background: In the field of Plastic Reconstructive Surgery the development of new innovative matrices for skin repair is in urgent need. The ideal biomaterial should promote attachment, proliferation and growth of cells. Additionally, it should degrade in an appropriate time period without releasing harmful substances, but not exert a pathological immune response. Spider dragline silk from Nephila spp meets these demands to a large extent. Methodology/Principal Findings: Native spider dragline silk, harvested directly out of Nephila spp spiders, was woven on steel frames. Constructs were sterilized and seeded with fibroblasts. After two weeks of cultivating single fibroblasts, keratinocytes were added to generate a bilayered skin model, consisting of dermis and epidermis equivalents. For the next three weeks, constructs in co-culture were lifted on an originally designed setup for air/liquid interface cultivation. After the culturing period, constructs were embedded in paraffin with an especially developed program for spidersilk to avoid supercontraction. Paraffin cross-sections were stained in Haematoxylin & Eosin (H&E) for microscopic analyses. Conclusion/Significance: Native spider dragline silk woven on steel frames provides a suitable matrix for 3 dimensional skin cell culturing. Both fibroblasts and keratinocytes cell lines adhere to the spider silk fibres and proliferate. Guided by the spider silk fibres, they sprout into the meshes and reach confluence in at most one week. A well-balanced, bilayered cocultivation in two continuously separated strata can be achieved by serum reduction, changing the medium conditions and the cultivation period at the air/liquid interphase. Therefore spider silk appears to be a promising biomaterial for the enhancement of skin regeneration.

description: Farb- und Helligkeitsunterschiede an glatten Sichtbetonflächen werden von einer Vielzahl von Einflussfaktoren beeinflusst. In der Planungsphase von Sichtbetonbauteilen wird die Farbe zumeist indirekt z. B. durch Verweis auf vergleichbare Bauwerke oder über Erprobungsflächen aus Beton eingegrenzt. Eine objektive und quantitative Festlegung findet jedoch nicht statt. Im Gegensatz dazu wird in vielen anderen Industriezweigen, wie z. B. der Automobil- oder Lebensmittelindustrie aber auch bei der Zementherstellung, die Lichtspektroskopie bzw. Farbmessung bereits erfolgreich zur quantitativen Farbmessung für Qualitätssicherungszwecke eingesetzt. Im vorliegenden Beitrag werden Einflüsse der Ausgansstoffe sowie einzelner betontechnologischer Eigenschaften auf die resultierende Farbe von Sichtbetonflächen systematisch und quantitativ mittels Lichtspektroskopie ermittelt und bewertet. Ferner wird die prinzipielle Eignung des Messverfahrens zur Anwendung in der Planungsphase glatter Sichtbetonflächen diskutiert.
description: Colour and luminance differences on exposed concrete are influenced by a large number of factors. In the planing phase the colour is usually specified by referencing to other – similar – structures or by providing hand samples. However, an objective and quantitative assessment does not take place. In contrast, in many other industries such as automotive or food industry but also in cement production, the light spectroscopy or colour measurement is already successfully used for quality control purposes with both colour and luminance being quality criteria. In the present paper the influence of the raw materials and concrete properties on the resulting colour of exposed concrete surfaces is systematically und quantitatively determined and evaluated by light spectroscopy. Furthermore, the application of the measuring method for use in the planning phase of smooth exposed concrete surfaces is evaluated.

description: The Jaynes-Cummings model describes the coupling between photons and a single two-level atom in a simplified representation of light-matter interactions. In circuit QED, this model is implemented by combining microwave resonators and superconducting qubits on a microchip with unprecedented experimental control. Arranging qubits and resonators in the form of a lattice realizes a new kind of Hubbard model, the Jaynes-Cummings-Hubbard model, in which the elementary excitations are polariton quasi-particles. Due to the genuine openness of photonic systems, circuit QED lattices offer the possibility to study the intricate interplay of collective behavior, strong correlations and non-equilibrium physics. Thus, turning circuit QED into an architecture for quantum simulation, i.e., using a well-controlled system to mimic the intricate quantum behavior of another system too daunting for a theorist to tackle head-on, is an exciting idea which has served as theorists' playground for a while and is now also starting to catch on in experiments. This review gives a summary of the most recent theoretical proposals and experimental efforts in this context.
