description: The flexural behavior of carbon fibre reinforced polymer (CFRP) reinforced concrete (RC) beams is investigated in this paper. For flexural strengthening of RC beams, total ten beams were cast and tested over an effective span of 3000 mm up to failure under monotonic and cyclic loads. The beams were designed as under-reinforced concrete beams. Eight beams were strengthened with bonded CFRP fabric in single layer and two layers which are parallel to beam axis at the bottom under virgin condition and tested until failure; the remaining two beams were used as control specimens. Static and cyclic responses of all the beams were evaluated in terms of strength, stiffness, ductility ratio, energy absorption capacity factor, compositeness between CFRP fabric and concrete, and the associated failure modes. The theoretical moment-curvature relationship and the load-displacement response of the strengthened beams and control beams were predicted by using FEA software ANSYS. Comparison has been made between the numerical (ANSYS) and the experimental results. The results show that the strengthened beams exhibit increased flexural strength, enhanced flexural stiffness, and composite action until failure. In this investigation CPRP strengthened beam gives appreciable ductility when compared to control beam.

description: At the peak of the extraordinary rise in interest rates in May, rates on long-term Treasury bonds were about one percentage point above the level at the end of April, The shift in the demand for Treasury bonds in May is broadly similar to the shift in the demand for dollars in the summer of 1979; almost every day brought a lower price than the day before. Shifts of this kind usually terminate when the anxiety that produced them is resolved.

description: In the activated carbon industry, high-temperature Steam Pipes are used in Rotary Kilns to activate charcoal. High temperature steam is used in rotary kiln to activate charcoal in activated carbon industry, steam pipe is inserted in the kiln under high temperature conditional environment. Excessive heat Steam, which is constantly and uniformly distributed across the activation region, is at the centre of the activation phase. The aim of this research is to look into the fractures that occur in the steam pipe during the process in the heat affected region. Two types of pipes were analysed using the finite element analysis method: those with straight holes and those without. To investigate the failure, total deformation, equal stress, and temperature distributions were calculated. A pipe's maximum holding time during the process will cause fractures to form, reducing the pipe's lifespan. Periodical cleaning and clinker removal of the pipe will increase the life of a pipe and the same time production of the respective product should not be affected.
Fermionic Minimal Dark Matter in 5D Gauge-Higgs Unification

description: We propose a Minimal Dark Matter (MDM) scenario in the context of a simple gauge-Higgs Unification (GHU) model based on the gauge group SU(3) x U(1)' in 5-dimensional Minkowski space with a compactification of the 5th dimension on S^1/Z_2 orbifold. A pair of vector-like SU(3) multiplet fermions in a higher-dimensional representation is introduced in the bulk, and the DM particle is identified with the lightest mass eigenstate among the components in the multiplets. In the original model description, the DM particle communicates with the Standard Model (SM) particles only through the bulk gauge interaction, and hence our model is the GHU version of the MDM scenario. There are two typical realizations of the DM particle in 4-dimensional effective theory: (i) the DM particle is mostly composed of the SM SU(2)_L multiplets, or (ii) the DM is mostly composed of the SM SU(2)_L singlets. Since the case (i) is very similar to the original MDM scenario, we focus on the case (ii), which is a realization of the Higgs-portal DM scenario in the context of the GHU model. We identify an allowed parameter region to be consistent with the current experimental constraints, which will be fully covered by the direct dark matter detection experiments in the near future. In the presence of the bulk multiplet fermions in higher-dimensional $SU(3)$ representations, we reproduce the 125 GeV Higgs boson mass through the renormalization group evolution of Higgs quartic coupling with the compactification scale of 10-100 TeV.

description: Commodity conversion assets play important economic roles. It is well known that the market value of these assets can be maximized by managing them as real options on the prices of their inputs and/or outputs. In particular, when futures on these inputs and outputs are traded, managing such real options, that is, valuing, hedging, and exercising them, is analogous to managing options on such futures, using risk neutral valuation and delta hedging methods. This statement holds because dynamically trading portfolios of these futures and a risk less bond can replicate the cash °ows of these assets. This basic principle is not always appreciated by managers of commodity conversion assets. Moreover, determining the optimal operational cash °ows of such an asset requires optimizing the asset operating policy. This issue complicates the real option management of commodity conversion assets. This chapter illustrates the application of this approach to manage a hydrocarbon cracker, a specific commodity conversion asset, using linear programming and Monte Carlo simulation. The discussion is based on a simplified representation of the operations of this asset. However, the material presented here has potential applicability to the real option management of more realistic models of hydrocarbon cracking assets, as well as other energy and commodity conversion assets.
Conditions on supersymmetry soft-breaking terms from GUTs

description: We study the effect of integrating out the heavy fields in a supersymmetric GUT which does not contain small mass parameters in the limit of exact supersymmetry. The trilinear ($A$) and bilinear ($B$) coefficients of the supersymmetry soft-breaking terms of the low-energy effective theory are related in a simple and model-independent way to those of the underlying theory. {}From these relations, we obtain the bound $|B|\ge 2$, which, together with the requirements of stability of the potential and electroweak symmetry breaking, imposes severe constraints on the space of allowed supersymmetric parameters. In models based on supergravity with a flat Kähler metric, we obtain $B=2$, instead of the relation $B=A-1$ usually used in phenomenological applications. The low-energy theory contains also a supersymmetric mass term $μ$ for the two Higgs doublets, which is of the order of the supersymmetry-breaking scale.

description: We investigate the detection prospects for gravitational lensing of three-dimensional maps from upcoming line intensity surveys, focusing in particular on the impact of gravitational nonlinearities on standard quadratic lensing estimators. Using perturbation theory, we show that these nonlinearities can provide a significant contaminant to lensing reconstruction, even for observations at reionization-era redshifts. However, we show how this contamination can be mitigated with the use of a "bias-hardened" estimator. Along the way, we present an estimator for reconstructing long-wavelength density modes, in the spirit of the "tidal reconstruction" technique that has been proposed elsewhere, and discuss the dominant biases on this estimator. After applying bias-hardening, we find that a detection of the lensing potential power spectrum will still be challenging for the first phase of SKA-Low, CHIME, and HIRAX, with gravitational nonlinearities decreasing the signal to noise by a factor of a few compared to forecasts that ignore these effects. On the other hand, cross-correlations between lensing and galaxy clustering or cosmic shear from a large photometric survey look promising, provided that systematics can be sufficiently controlled. We reach similar conclusions for a single-dish survey inspired by CII measurements planned for CCAT-prime, suggesting that lensing is an interesting science target not just for 21cm surveys, but also for intensity maps of other lines.

description: Based on an interpretation of the literature of phencyclidine (PCP) together with an examination of the relevant models or prototype structures, this research has attempted to design and synthesize a rigid analog of the phencyclidine structure. The parent ring systems suggested for this study were the 1-arnino and 2-arninornethyltetralins, 10 and, 12.

Several organic compounds, based on this design, have been prepared by classical examples of reductive alkylation reactions of the corresponding 2-hydroxyciethylene-1-tetralones, 11.., and by the condensation and subsequent reductive alkylation of the 1-arninotetralin, 9. These arninomethyltetralones, 28, 29 and 30, together with an example of a substituted 1-arninotetralin, 32, have been prepared and properly characterized using classical analytical and spectral techniques. These compounds are illustrated below.

The biological evaluation of these compounds remains incomplete due to the general insolubility of the respective hydrochlorides of arninomethyltetralone. Based on the preliminary data obtained from intraperitoneal injections of three of these compounds, 28, 29., and, 32, as well as intracerebroventricular injections, all in mice, it would appear that these compounds do not possess any PCP agonist or antagonist activity.

description: We report time-domain observation of vacuum Rabi oscillations in a single quantum dot strongly coupled to a nanocavity under incoherent optical carrier injection. We realize a photonic crystal nanocavity with a very high quality factor of >80,000 and employ it to clearly resolve the ultrafast vacuum Rabi oscillations by simple photoluminescence-based experiments. We found that the time-domain vacuum Rabi oscillations were largely modified when changing the pump wavelength and intensity, even when marginal changes were detected in the corresponding photoluminescence spectra. We analyze the measured time-domain oscillations by fitting to simulation curves obtained with a cavity quantum electrodynamics model. The observed modifications of the oscillation curves were mainly induced by the change in the carrier capture and dephasing dynamics in the quantum dot, as well as the change in bare-cavity emission. This result suggests that vacuum Rabi oscillations can be utilized as a highly sensitive probe for the quantum dot dynamics. Our work points out a powerful alternative to conventional spectral-domain measurements for a deeper understanding of the vacuum Rabi dynamics in quantum dot-based cavity quantum electrodynamics systems.

description: Sand Columns (SC) commonly known as Sand Compaction Piles (SCP) now has been vastly used for reinforcing the range of soft soils. The installation of sand columns improves the ultimate bearing ability of soft soil, accelerates stabilisation, prevents liquefaction in loose sandy soils, and provides lateral resistance to horizontal movement. The aim of this study is to create small scale laboratory models to investigate the effects of floating columns in clayey soil with silty deposits. The laboratory experiments were carried out on a circular column with a diameter of 37 mm, and the results of the treated and untreated ground were compared. The effects of sand columns on soils with varying shear strengths (low-medium-high), slenderness ratios (L/D), and loading patterns are studied. By varying the spacing between the columns, the group effect was also investigated. The stiffness of composite ground was calculated by loading the entire area of the test model, and the axial ability of the sand column was determined by loading the column area alone. According to the findings of the current report, a sand column will significantly improve the engineering properties of soft clayey soil. The group effect was also investigated, and it was discovered that raising the distance between the columns reduces group efficiency. As the distance between the columns is increased, the axial potential of the sand columns decreases.

description: We describe a new algebraic technique for enumerating self-avoiding walks on the rectangular lattice. The computational complexity of enumerating walks of $N$ steps is of order $3^{N/4}$ times a polynomial in $N$, and so the approach is greatly superior to direct counting techniques. We have enumerated walks of up to 39 steps. As a consequence, we are able to accurately estimate the critical point, critical exponent, and critical amplitude.

description: We have experimentally investigated the density of states (DOS) in Nb/Ni (S/F) bilayers as a function of Ni thickness, $d_F$. Our thinnest samples show the usual DOS peak at $\pmΔ_0$, whereas intermediate-thickness samples have an anomalous ``double-peak'' structure. For thicker samples ($d_F \geq 3.5$ nm), we see an ``inverted'' DOS which has previously only been reported in superconductor/weak-ferromagnet structures. We analyze the data using the self-consistent non-linear Usadel equation and find that we are able to quantitatively fit the features at $\pmΔ_0$ if we include a large amount of spin-orbit scattering in the model. Interestingly, we are unable to reproduce the sub-gap structure through the addition of any parameter(s). Therefore, the observed anomalous sub-gap structure represents new physics beyond that contained in the present Usadel theory.

description: During the period 1966.5 - 2006.2 the 15GHz and 8GHz lightcurves of 3C454.3 (z=0.859) show a qsasi-periodicity of ~12.8 yr (~6.9 yr in the rest frame of the source) with a double-bump structure. This periodic behaviour is interpreted in terms of a rotating double-jet model in which the two jets are created from the black holes in a binary system and rotate with the period of the orbital motion. The periodic variations in the radio fluxes of 3C454.3 are suggested to be mainly due to the lighthouse effects (or the variation in Doppler boosting) of the precessing jets which are caused by the orbital motion. In addition, variations in the mass-flow rates accreting onto the black holes may be also involved.

L'oléiculture traditionnelle ne peut survivre qu'en améliorant les revenus de l'oléiculteur et en reconnaissant son rôle multifonctionnel. L'Italie est le deuxième producteur d'huile d'olive de l'Union européenne et l'Ombrie peut être considérée comme l'une des régions les plus intéressantes en raison de la qualité de sa production d'huile d'olive extra vierge couplée à sa mise en valeur des savoirs traditionnels et de l'environnement local. L'industrie régionale d'huile d'olive regroupe environ 30 000 exploitations oléicoles couvrant environ 27 000 ha et comprenant 270 huileries. La phase de production de l'huile d'olive comprend l'extraction de l'huile et de sous-produits supplémentaires (eau, grignons et peaux). La gestion des sous-produits est très importante. Les déchets de l'huile d'olive ont un impact important sur les sols et les eaux, en raison de leur phytotoxicité élevée (phénols, lipides et acides organiques). D'autre part, ces déchets peuvent être potentiellement précieux.

description: The knowledge of the downlink (DL) channel spatial covariance matrix at the BS is of fundamental importance for large-scale array systems operating in frequency division duplexing (FDD) mode. In particular, this knowledge plays a key role in the DL channel state information (CSI) acquisition. In the massive MIMO regime, traditional schemes based on DL pilots are severely limited by the covariance feedback and the DL training overhead. To overcome this problem, many authors have proposed to obtain an estimate of the DL spatial covariance based on uplink (UL) measurements. However, many of these approaches rely on simple channel models, and they are difficult to extend to more complex models that take into account important effects of propagation in 3D environments and of dual-polarized antenna arrays. In this study we propose a novel technique that takes into account the aforementioned effects, in compliance with the requirements of modern 4G and 5G system designs. Numerical simulations show the effectiveness of our approach.

description: Many urban development projects today are complex high-rise buildings that face specific challenges such as municipal building ordinances and limitations, adjoining public and residential areas, narrow sidewalks and streets, and underground utilities, all of which necessitate careful planning and tight schedules. A major challenge for such projects is developing practical schedules that enable them to reach contractual completion dates while working with limited resources and budgets. The present scheduling software products used in construction projects, such as Primavera P6, Microsoft Project, and others, are not actually used as a scheduling tool in realistic construction projects, which depend on Microsoft Excel or a bar-chart instead. This is due to the fact that current scheduling systems are unable to include a more user-friendly schedule format, such as two-way multiple overlapping relationships. In 2010, the BDM (beeline diagramming method) was proposed as a new networking technique to address this shortcoming. However, in a traditional schedule computation method, two-way multiple overlapping relationships produce the loop. Construction schedules can be a useful tool for managing, controlling, and supporting the complex processes involved in any construction projects. This paper discusses the two-way multiple overlapping relationships loop phenomenon in a BDM network, suggests solutions, and then shows a realistic implementation of two-way multiple overlapping relationships in a specific project.

description: The incorporation of rational expectations into economic models is widely recognized as one of the more significant advances in economic theory during the past decade. The advances are methodological—improvements in the methods economists use to derive the implications of dynamic models and the treatment of unanticipated changes. Many of the substantive benefits of the methods remain in the future, however. The reason is that the models used to illustrate rational expectations typically endow people with more information than they usually have.

description: We consider $Z^d$, with d bigger or equal to three. We investigate the vacant set of random interlacements in the strongly percolative regime, the vacant set of the simple random walk, and the excursion set above a given level of the Gaussian free field in the strongly percolative regime. We derive asymptotic upper and lower exponential bounds for the large deviation probability that the adequately thickened component of the boundary of a large box centered at the origin in the respective vacant sets or excursion set leaves in the box a macroscopic volume in its complement. We also derive geometric information on the shape of the left-out volume. It is plausible, but open at the moment, that certain critical levels coincide, both in the case of random interlacements and of the Gaussian free field. If this holds true, the asymptotic upper and lower bounds that we obtain are matching in principal order for all three models, and the macroscopic holes are nearly spherical. We heavily rely on the recent work arXiv:1706.07229 by Maximilian Nitzschner and the author for the coarse graining procedure, which we employ in the derivation of the upper bounds.

description: Obstacle avoidance is an important concept to be considered when a robotic system is installed in an environment. Obstacles within the working space of a robotic system can prevent the robot from performing the tasks assigned to it properly; hence, the designer of the robotic system must program the robot to follow an emergency strategy that enables it to avoid any contact with a probable obstacle anywhere anytime within the working space of the robot. For mobile robots, this task is relatively easier to accomplish since these robots have the flexibility to change their routes and take alternatives that are free of obstacles. For fixed robotic manipulators the situation is much more complex because in this case the only way to avoid an obstacle is to change the spatial configuration of the robotic manipulator which requires a sophisticated solution for the inverse kinematics problem of such redundant robotic systems. This is not an easy task however. In this paper, we are only concerned with obstacle avoidance techniques and present a real-time obstacle avoidance method for fixed, highly redundant robotic manipulators that combines the benefits of both global and local techniques in that it can be used for both static and dynamic environments with a reduced computational effort.
Rational and Irrational Bubbles

description: The subject of this conference is an esoteric issue in rational expectations, general equilibrium modeling. The issue arises because it is not possible to show that models of this kind converge to a unique, stationary equilibrium or dynamic equilibrium path. There are potentially multiple equilibria, and among them are some in which prices of assets or output do not converge to finite values. Prices can explode. A technical reason why a model may have bubble solutions is that there may not be an infinitely lived rational decision-maker who breaks the bubble.

description: We present the results of detailed nuclear shell model calculations of the spin-dependent elastic cross section for neutralinos scattering from \si29 and \ge73. The calculations were performed in large model spaces which adequately describe the configuration mixing in these two nuclei. As tests of the computed nuclear wave functions, we have calculated several nuclear observables and compared them with the measured values and found good agreement. In the limit of zero momentum transfer, we find scattering matrix elements in agreement with previous estimates for \si29 but significantly different than previous work for \ge73. A modest quenching, in accord with shell model studies of other heavy nuclei, has been included to bring agreement between the measured and calculated values of the magnetic moment for \ge73. Even with this quenching, the calculated scattering rate is roughly a factor of 2 higher than the best previous estimates; without quenching, the rate is a factor of 4 higher. This implies a higher sensitivity for germanium dark matter detectors. We also investigate the role of finite momentum transfer upon the scattering response for both nuclei and find that this can significantly change the expected rates. We close with a brief discussion of the effects of some of the non-nuclear uncertainties upon the matrix elements.

description: Magnetic reconnection is the most likely mechanism responsible for the high temperature events that are observed in strongly magnetized locations around the temperature minimum in the low solar chromosphere. This work improves upon our previous work ["Magnetic Reconnection in Strongly Magnetized Regions of the Low Solar Chromosphere", The Astrophysical Journal 852, 95 (2018) ] by using a more realistic radiative cooling model computed from the OPACITY project and the CHIANTI database. We find that the rate of ionization of the neutral component of the plasma is still faster than recombination within the current sheet region. For low $β$ plasmas, the ionized and neutral fluid flows are well-coupled throughout the reconnection region resembling the single-fluid Sweet-Parker model dynamics. Decoupling of the ion and neutral inflows appears in the higher $β$ case with $β_0=1.46$, which leads to a reconnection rate about three times faster than the rate predicted by the Sweet-Parker model. In all cases, the plasma temperature increases with time inside the current sheet, and the maximum value is above $2\times10^4$~K when the reconnection magnetic field strength is greater than $500$~G. While the more realistic radiative cooling model does not result in qualitative changes of the characteristics of magnetic reconnection, it is necessary for studying the variations of the plasma temperature and ionization fraction inside current sheets in strongly magnetized regions of the low solar atmosphere. It is also important for studying energy conversion during the magnetic reconnection process when the hydrogen-dominated plasma approaches full ionization.

description: We describe a new algebraic technique, utilising transfer matrices, for enumerating self-avoiding lattice trails on the square lattice. We have enumerated trails to 31 steps, and find increased evidence that trails are in the self-avoiding walk universality class. Assuming that trails behave like $A λ^n n^{11 \over 32}$, we find $λ= 2.72062 \pm 0.000006$ and $A = 1.272 \pm 0.002$.

Weak-strong uniqueness for the general Ericksen-Leslie system in three dimensions

description: We study the Ericksen-Leslie system equipped with a quadratic free energy functional. The norm restriction of the director is incorporated by a standard relaxation technique using a double-well potential. We use the relative energy concept, often applied in the context of compressible Euler- or related systems of fluid dynamics, to prove weak-strong uniqueness of solutions. A main novelty is that the relative energy inequality is proved for a system with a nonconvex energy.

description: This review summarises the safe production of osmium and its compounds and its functionality from both the chemistry and materials perspectives. Osmium (Os) is one of the platinum group metals. A review of the available data shows that there is a lot of potential for osmium (II) compounds to be used for traffic signalling as molecular signal gates using electrochemical generated power. Osmium (II) compounds can also be used for biomedical applications on the development of anti-cancer drugs. Organic compounds of osmium have also been found to possess excellent electrochemical properties which are useful for redox flow battery. This review of osmium and its compounds possess a variety of correlated properties with a potential to put an emergent demand on osmium for various applications. The results proved that Os complexes have excellent electrochemical properties and has rendered Os complexes as “smart complexes”.

description: Nonequilibrium many-body dynamics is becoming one of the central topics of modern condensed matter physics. Floquet topological states were suggested to emerge in photodressed band structures in the presence of periodic laser driving. Here we propose a viable nonequilibrium route without requiring coherent Floquet states to reach the elusive magnetic Weyl semimetallic phase in pyrochlore iridates by ultrafast modification of the effective electron-electron interaction with short laser pulses. Combining \textit{ab initio} calculations for a time-dependent self-consistent reduced Hubbard $U$ controlled by laser intensity and nonequilibrium magnetism simulations for quantum quenches, we find dynamically modified magnetic order giving rise to transiently emerging Weyl cones that are probed by time- and angle-resolved photoemission spectroscopy. Our work offers a unique and realistic pathway for nonequilibrium materials engineering beyond Floquet physics to create and sustain Weyl semimetals. This may lead to ultrafast, tens-of-femtoseconds switching protocols for light-engineered Berry curvature in combination with ultrafast magnetism.

description: Query optimization problems for expensive predicates have received much attention in the database community. In these situations, the output to the database query is a set of tuples that obey certain conditions, where the conditions may be expensive to evaluate computationally. In the simplest case when the query looks for the set of tuples that simultaneously satisfy two expensive conditions on the tuples and these can be checked in two different distributed processors, the problem reduces to one of ordering the condition evaluations at each processor to minimize the time to output all the tuples that are answers to the query. We improve upon a previously known deterministic 3-approximation for this problem: In the case when the times to evaluate all conditions at both processors are identical, we give a 2-approximation; In the case of non-uniform evaluation times, we present a 8/3 -approximation that uses randomization. While it was known earlier that no deterministic algorithm (even with exponential running time) can achieve a performance ratio better than 2, we show a corresponding lower bound of 3/2 for any randomized algorithm.
