description: We examine the theta-expansion of the eleven-dimensional supervielbein. We outline a systematic procedure which can be iterated to any order. We give explicit expressions for the vielbein and three-form potential components up to order ${\cal O}(þ^5)$. Furthermore we show that at each order in the number of supergravity fields, in a perturbative expansion around flat space, it is possible to obtain exact expressions to all orders in theta. We give the explicit expression at linear order in the number of fields and we show how the procedure can be iterated to any desired order. As a byproduct we obtain the complete linear coupling of the supermembrane to the background supergravity fields, covariantly in component form. We discuss the implications of our results for M(atrix) theory.

description: The financial support under the Common Agricultural Policy in Poland is increasing and it is additionally supported by domestic payments. It should accelerate the convergence between incomes in polish farms in relation to EU average. The main aim of this article was to examine the farm incomes in Poland against a background of EU-15 member states using data that is available in FADN database. Such a profitability is lower in comparison with EU-15, both gross and net. It depends not only on direct payments but also on general economic situation and production structure in polish agriculture. The incomes of farmers households still remain lower in comparison with the national average. They are characterised by higher variability, dependent on agricultural commodity prices and supply-demand relations. The reinforcing of the family agriculture model that provides social and ecological functions will be possible if aid instruments are maintained. / Synopsis. Wsparcie finansowe rolnictwa w ramach Wspólnej Polityki Rolnej w Polsce wzrasta i dodatkowo zasilana jest przez płatności krajowe. Powinno to przyspieszyć konwergencję dochodów gospodarstw polskich w relacji do średniej unijnej. Celem artykułu było zbadanie dochodowości polskich gospodarstw rolnych na tle krajów UE-15 mierzonej wielkościami dostępnymi w bazie FADN. Dochodowość ta jest niższa w porównaniu do krajów UE, zarówno w ujęciu brutto, jak i netto. Uzależniona jest ona nie tylko od dopłat unijnych, ale także od ogólnej koniunktury gospodarczej oraz struktur wytwórczych polskiego rolnictwa. Dochody ludności rolniczej w Polsce pozostają niższe w porównaniu do przeciętnej ogólnokrajowej. Charakteryzują się też większą zmiennością, zależną m.in. od cen surowców rolnych i relacji popytowo- podażowych. Wzmacnianie rodzinnego modelu rolnictwa, realizującego też funkcje społeczne i ekologiczne, wymaga utrzymania mechanizmów pomocowych.

description: Precipitation and dissolution are prime processes in carbonate rocks and being able to monitor them is of major importance for aquifer and reservoir exploitation or environmental studies. Electrical conductivity is a physical property sensitive both to transport phenomena of porous media and to dissolution and precipitation processes. However, its quantitative use depends on the effectiveness of the petrophysical relationship to relate the electrical conductivity to hydrological properties of interest. In this work, we develop a new physically-based model to estimate the electrical conductivity by upscaling a microstructural description of water-saturated fractal porous media. This model is successfully compared to published data from both unconsolidated and consolidated samples, or during precipitation and dissolution numerical experiments. For the latter, we show that the permeability can be linked to the predicted electrical conductivity.

Counter terms of unnatural parity at next-to-leading order with unknown couplings are important to acommodate the results both to the experimental decay width and the photon spectrum. The presence of these coefficients does not allow for a determination of the number of colors from these decays.

Visualizing the design and construction of roadway system : a case study
Creators: name: Beheshtian, Seyed Mahdi
Publisher: name: University of British Columbia
Year: 2010

description: Effective planning and scheduling of construction operations is critical for the success of any construction project. Visualization tools provide engineers with more understanding of and insight into construction project information. The main objective of this research is to investigate the capabilities of existing state-of-the-art software to create realistic visualizations of the design and construction of transportation systems. This research was funded by the Ministry of Transportation, which requires realistic visualizations of their transportation projects to communicate with different stakeholders. The research focused on part of the South Fraser Perimeter Road project, whch is part of the Gateway Program. The project included a four-lane, 490m bridge and approaches to the bridge. To provide a visualization of the construction process, I utilized existing 4D (3D + time) modeling tools. In this method, a 3D model of the bridge is connected to the construction schedule to create an animation of the construction process that represents how and when the structure will be built. I also utilized landscape visualization software to enhance the realism of the project surroundings. During the course of this project, I learned many lessons regardug the capabilities of the software tools. The process of 3D modeling should be accomplished with constant connection with the designer and client, and the 3D design process should be planned beforehand. Also, the scale and position of each object and its relation to other objects in the 3D model should be carefully considered before exporting to 4D software. In the 4D modeling process, the schedule should be reviewed thoroughly before connecting each task to the 3D objects in the 4D model. Finally, 4D modeling software has limited rendering power. To create truly realistic renderings requires more powerful software tools, whch currently have limited compatibility with 4D software. In this case study, I found that although there is room for improvement, existing technologies are capable of creating effective visualizations of the construction process that are helpful in communicating to a variety of stakeholders. However, significant work is needed to develop visualizations that are capable of realistically representing the project environment.

description: The accretion induced neutron star magnetic field evolution is studied through considering the accretion flow to drag the field lines aside and dilute the polar field strength, and as a result the equatorial field strength increases and is buried inside the crust. The main conclusions of model are as follows: (i) the polar field decays with increasing the accreted mass; (ii) The bottom magnetic field strength of about $10^8$ G can occur when neutron star magnetosphere radius approaches the star radius, which depends on the accretion rate as $\mdot^{1/2}$; (iii) The neutron star magnetosphere radius decreases with accretion until it reaches the star radius, and its evolution is little influenced by the initial field and the accretion rate after accreting $\sim 0.01 \ms$, which implies that the magnetosphere radii of neutron stars in LMXBs would be homogeneous for Z sources and Atoll sources if they accreted the comparable masses. As an extension, the physics effects of the possible strong magnetic zone in the X-ray neutron stars and recycled pulsars are discussed. Moreover, The strong magnetic fields in the binary pulsars PSR 1831-00 and PSR 1718-19 after accreting about half solar mass in the binary accretion phase, $8.7\times10^{10}$ G and $1.28\times10^{12}$ G, respectively, can be explained through considering the incomplete frozen flow in the polar zone. As a model's expectation, the existence of the low magnetic field ($\sim 3\times 10^{7}$ G) neutron stars or millisecond pulsars is suggested.

Ordinary Skyrmions resemble polyhedral shells, whereas the Hopf-type solutions of the Skyrme-Faddeev model look like closed loops, possibly linked or knotted. By looking at the minimal-energy solutions in various topological classes, and for various values of the parameter, we see how the polyhedral Skyrmions deform into loop-like Hopf Skyrmions.

description: The aim of the paper was to make a typology of European Union countries based on the variables characterizing and/or determining the level of use of veterinary services. The research was conducted with the use of comparative analysis, and the typological groups of European Union countries were separated by Ward’s method. On the basis of the analysis of relevant economic indicators four typological groups (types) of European Union countries were separated. It may be noted that the value of veterinary services is related to the size of the livestock, which naturally induces the necessity of the use of these services, as well as the intensity of livestock production. In addition, the degree of use of veterinary services is determined by the level of economic development of the country, and agriculture. Hence, the role of these services in agriculture in highly developed countries, where there is a greater propensity to use external services, is significant. / Synopsis. Celem artykułu było utworzenie typologii krajów Unii Europejskiej w oparciu o zmienne charakteryzujące i/lub determinujące poziom korzystania z usług weterynaryjnych. Badanie wykonano z zastosowaniem metody analizy porównawczej, a grupy typologiczne krajów Unii Europejskiej wyodrębniono metodą Warda. Na podstawie analizy wartości wskaźników mających znaczenie ekonomiczne i statystyczne, wyodrębniono cztery grupy typologiczne (typy) państw Unii Europejskiej. Można zauważyć, że wartość usług weterynaryjnych jest związana z wielkością pogłowia zwierząt gospodarskich, które w naturalny sposób narzuca konieczność korzystania z tych usług oraz z intensywnością produkcji zwierzęcej. Ponadto stopień korzystania z usług weterynaryjnych wynika z poziomu rozwoju gospodarczego państwa, a tym samym i rolnictwa, stąd istotne znaczenie tych usług w rolnictwie krajów wysoko rozwiniętych, w których występuje większa skłonność do korzystania z usług zewnętrznych.

There are many motives in mergers and acquisitions. The study focused on the motives and benefits of processes concentration, explained by the theory of transaction costs. It was shown that transaction costs can be reduced through mergers and acceptance, which leads to internalization of the company's activities. In addition, transnational corporations improve their global efficiency by conducting fiscal policy and optimization of the tax burden. / Synopsis.

description: Many state-of-the-art technologies developed in recent years have been influenced by machine learning to some extent. Most popular at the time of this writing are artificial intelligence methodologies that fall under the umbrella of deep learning. Deep learning has been shown across many applications to be extremely powerful and capable of handling problems that possess great complexity and difficulty. In this work, we introduce a new layer to deep learning: the fuzzy layer. Traditionally, the network architecture of neural networks is composed of an input layer, some combination of hidden layers, and an output layer. We propose the introduction of fuzzy layers into the deep learning architecture to exploit the powerful aggregation properties expressed through fuzzy methodologies, such as the Choquet and Sugueno fuzzy integrals. To date, fuzzy approaches taken to deep learning have been through the application of various fusion strategies at the decision level to aggregate outputs from state-of-the-art pre-trained models, e.g., AlexNet, VGG16, GoogLeNet, Inception-v3, ResNet-18, etc. While these strategies have been shown to improve accuracy performance for image classification tasks, none have explored the use of fuzzified intermediate, or hidden, layers. Herein, we present a new deep learning strategy that incorporates fuzzy strategies into the deep learning architecture focused on the application of semantic segmentation using per-pixel classification. Experiments are conducted on a benchmark data set as well as a data set collected via an unmanned aerial system at a U.S. Army test site for the task of automatic road segmentation, and preliminary results are promising.

description: The article attempts to identify the most important determinants of development for the meat and poultry industries in Poland after accession to the European Union and the prospects of development for these two industries. The most important factors influencing the dynamic development of the meat and poultry industry in our country in the last decade undoubtedly included Poland's accession to the European Union, and the related opening of a large and wealthy market for our food. Appropriate preparation of the processing plants for open competition and the use of existing competitive advantages were also significant. The Polish meat industry and poultry industry in particular have made good use of the opportunity for dynamic development and expansion to foreign markets that opened up for them in 2004. / Synopsis. W artykule podjęto próbę wskazania najważniejszych determinant rozwoju przemysłu mięsnego i drobiarskiego w Polsce po przystąpieniu do Unii Europejskiej oraz perspektyw rozwoju obydwu branż. Do najważniejszych czynników mających wpływ na szybki rozwój przemysłu mięsnego oraz drobiarskiego w naszym kraju w minionej dekadzie, zaliczyć można wejście Polski do Unii Europejskiej, a w ślad za tym otwarcie dużego i zamożnego rynku zbytu na naszą żywność. Nie bez znaczenia było też odpowiednie przygotowanie samych zakładów przetwórczych do otwartej konkurencji oraz wykorzystanie posiadanych przewag komparatywnych. Polski przemysł mięsny, a zwłaszcza drobiarski dobrze wykorzystały szansę do szybszego rozwoju i ekspansji na rynki zagraniczne, jaka się przed nim otworzyła po 2004 roku.

description: We discuss how the geometric theory of differential equations can be used for the numerical integration and visualisation of implicit ordinary differential equations, in particular around singularities of the equation. The Vessiot theory automatically transforms an implicit differential equation into a vector field distribution on a manifold and thus reduces its analysis to standard problems in dynamical systems theory like the integration of a vector field and the determination of invariant manifolds. For the visualisation of low-dimensional situations we adapt the streamlines algorithm of Jobard and Lefer to 2.5 and 3 dimensions. A concrete implementation in Matlab is discussed and some concrete examples are presented.

description: The first-principles description of liquid water using ab initio molecular dynamics (AIMD) based on Density Functional theory (DFT) has recently been found to require long equilibration times, giving too low diffusivities and a clear over-structuring of the liquid. In the light of these findings we compare here the room-temperature description offered by two different exchange correlation functionals: BLYP, the most popular for liquid water so far, and RPBE, a revision of the widely used PBE. We find for RPBE a less structured liquid with radial distribution functions closer to the experimental ones than the ones of BLYP. The diffusivity obtained with RPBE for heavy water is still 20% lower than the corresponding experimental value, but it represents a substantial improvement on the BLYP value, one order of magnitude lower than experiment. These characteristics and the hydrogen-bond (HB) network imperfection point to an effective temperature ~3% lower than the actual simulation temperature for the RPBE liquid, as compared with BLYP's ~17% deviation. The too long O--O average nearest-neighbor distance observed points to an excessively weak HB, possibly compensating more fundamental errors in the DFT description.

description: This study examines and compares the energy consumption of 15 residential buildings by evaluating the energy bills of the past seven years (2011-2017). The resulting consumption data are compared with the calculated demand values from the respective energy certificates. The informative value of the energy performance certificates is checked in this way and analyzes of deviating results are made. Furthermore, the energy costs for heating and hot water are taken from the bills and then the influence of various parameters and characteristics of the objects on their total costs are examined. The examined residential buildings are located in the metropolitan area of Vienna and form a mix of different building and energy classes, years of construction, size of apartment and number of residential units per object or component. In the present study, the consumption data of 1348 apartments, which are divided into a total of 49 components, are statistically recorded and evaluated. These objects provide a overview of the consumption behavior of the residential buildings themselves, as well as the user behavior of the respective units and are to be understood as a survey of the current consumption situation and the resulting costs.

description: The aim of the study was to identify and examine an elasticity of relations between production factors (land, labour, capital) and incomes gained by using the above mentioned factors at farms of four macro-regions FADN, i.e.: Pomorze and Mazury, Wielkopolska and Śląsk, Mazowsze and Podlasie, Małopolska and Pogórze. Production function models of Cobb-Douglas (C-D) were assessed for every macro-region for years: 2010, 2011 and 2012. The survey shows that in all macro-regions as well as in all surveyed years, elasticity coeffi cient of total net added value was higher than 1 which means increasing incomes in scale. Increase of net added value in three among four surveyed macro-regions depended mainly on land factor while labour input (excluding Mazowsze and Podlasie where labour factor was important) and fi xed assets factor appeared to be of least importance.

description: A possibility of the crystalline state of nuclear matter is discussed in a medium--modified Skyrme model. The interaction energy per nucleon in nuclear matter is evaluated by taking into account the medium influence on single nucleon--skyrmion properties and the tensor part of the nucleon--nucleon potential, and by using a variational method of Hartree--Fock type including zero--point quantum fluctuations. It is shown that in this approach the ground state of nuclear matter has no crystalline structure due to quantum fluctuations as well as medium modifications of hadron properties.

description: The aim of the study was to evaluate the changes in the number of plants and fl owers wholesale companies in Poland. Analyses focused on the number of fi rms engaged in wholesale trade and the structure of employment in these companies. The investigations also included the location of the analysed companies in relation to the number of people in each voivodeship. Research period covered the years 2002-2012. The fi rst year of the analysed period was referred to as of 100%. The dynamics of changes and average annual changes in the number of existing companies and start-ups were analysed. The Główny Urząd Statystyczny yearbooks, and i.a. the ones of the Polska Klasyfi kacja Działalności [the abbreviation in Polish: PKD], served as data sources. The performed investigations reveal that the number of fi rms of the discussed line of business in the investigated period increased very clearly and this rise took the form of a linear trend. What is more, the number of the wholesale companies in particular voivodeships matched the agglomerations of consumers.
Reactive molecular dynamics at constant pressure via non-reactive force fields: extending the Empirical Valence Bond method to the isothermal-isobaric ensemble

description: The Empirical Valence Bond (EVB) method offers a suitable framework to obtain reactive potentials through the coupling of non-reactive force fields. However, most of the implemented functional forms for the coupling terms depend on complex spatial coordinates, which precludes the computation of the stress tensor for condensed phase systems and prevents the possibility to carry out EVB molecular dynamics in the isothermal-isobaric (NPT) ensemble. In this work, we make use of coupling terms that depend on the energy gaps, defined as the energy differences between the participating non-reactive force fields, and derive an expression for the EVB stress tensor suitable for computations. Implementation of this new methodology is tested for a model of a single reactive malonaldehyde solvated in non-reactive water. Computed densities and classical probability distributions in the NPT ensemble reveals a negligible role of the reactive potential in the limit of low concentrated solutions, thus corroborating the validity of standard approximations customarily adopted for EVB simulations.

description: The term defect tolerance is widely used in literature to describe materials such as lead-halides which exhibit long non-radiative lifetimes of carriers despite possessing a large concentration of point defects. Studies on defect tolerance of materials mostly look at the properties of the host material and/or the chemical nature of defects that affect the capture coefficients of defects. However, the recombination activity of a defect is not only a function of its capture coefficients alone but are also dependent on the electrostatics and the design of the layer stack of a photovoltaic device. Here we study the influence of device geometry on defect tolerance by combining calculations of capture coefficients with device simulations. We derive generic device design principles which can inhibit recombination inside a photovoltaic device for a given set of capture coefficients based on the idea of slowing down the slower of the two processes (electron and hole capture) even further by modifying electron and hole injection into the absorber layer. We use the material parameters and typical p-i-n device geometry representing methylammonium lead halide perovskites solar cells to illustrate the application of our generic design principles to improve specific devices .

description: The domestic windows in the exterior building facade play a significant role in sound insulation against outdoor airborne noise. The prediction of their acoustic performances is classically carried out in laboratory according to standard ISO 10140. In this work, a 3D elasto-acoustic finite element model (FEM) is proposed to predict the sound reduction index of three different glazing configurations of domestic window, which are compared to laboratory measurements. Two acoustic cavities with rigid-boundaries on both sides of the window are used to simulate respectively the diffuse field on the source side and the pressure field on the receiver side. By using a simplified FEM for the double glazed windows, the sound reduction index is calculated from the difference between the source and receiving sound pressure levels in the one-third octave band from 100 to 500 Hz.
Tachyon Dynamics in Open String Theory

description: In this review we describe our current understanding of the properties of open string tachyons on an unstable D-brane or brane-antibrane system in string theory. The various string theoretic methods used for this study include techniques of two dimensional conformal field theory, open string field theory, boundary string field theory, non-commutative solitons etc. We also describe various attempts to understand these results using field theoretic methods. These field theory models include toy models like singular potential models and p-adic string theory, as well as more realistic version of the tachyon effective action based on Dirac-Born-Infeld type action. Finally we study closed string background produced by the `decaying' unstable D-branes, both in the critical string theory and in the two dimensional string theory, and describe the open string completeness conjecture that emerges out of this study. According to this conjecture the quantum dynamics of an unstable D-brane system is described by an internally consistent quantum open string field theory without any need to couple the system to closed strings. Each such system can be regarded as a part of the `hologram' describing the full string theory.

description: Purported signatures of collective dynamics in small systems like proton-proton (pp) or proton-nucleus (p-A) collisions still lack unambiguous understanding. Despite the qualitative and/or quantitative agreement of the data to hydrodynamic models, it has remained unclear whether the harmonic flows in small systems relate to the common physical picture of hydrodynamic collectivity driven by the initial geometry. In the present work, we aim to address this issue by invoking a novel concept of Event Shape Engineering (ESE), which has been leveraged to get some control of the initial geometry in high-energy heavy-ion collisions. We utilise ESE by constructing a reference flow vector, $q_{2}$ that allows to characterise an event based on it's ellipticity. Applying this technique on a data set, simulated from a 3+1D viscous hydrodynamic model EPOS3, we study the event-shape dependent modifications to some of the bulk properties like, inclusive transverse momentum ($p_{T}$) spectra and $p_{T}$-differential $v_{2}$ for p-Pb collisions at 5.02 TeV. Selecting events on the basis of different magnitudes of reference flow vector $q_{2}$, we observe a hint of event-shape induced modifications of $v_{2}$ as a function of $p_{T}$ but, the inclusive $p_{T}$-spectra of charged particles seem to be insensitive to this event-shape selection.

Out-of-plane seismic performance of unreinforced clay brick masonry walls

Publisher: name: University of British Columbia

description: Given sufficient anchorage to the diaphragms, out-of-plane walls in unreinforced masonry buildings have been shown to crack above mid-height and rock as two rigid bodies. This study investigates the sensitivity of the rocking response to the type of ground motion and the quality of the wall construction. A parametric study using a nonlinear-elastic single-degree-of-freedom model suggests that buildings located on firm ground sites are less likely to experience out-ofplane wall failures compared with buildings located on soft soil sites. Shake table tests were conducted on four full-scale multi-wythe walls with a height-to-thickness (h/t) ratio of 12, varying construction quality, and using three different ground motions. All walls experienced cracking at approximately peak ground acceleration (PGA) of the 2005 National Building Code of Canada (NBCC) level for Vancouver, but exhibited a stable rocking behaviour without collapse beyond a ground motion 1.5 times the 2005 NBCC level. Simple analytical methods were used to calculate the un-cracked wall stiffness, maximum force on an un-cracked wall, cracking strength, and the maximum total force acting on a cracked wall. These results compared well with those observed in the tests. Finally, a rigid body numerical model was developed using the commercially available software, Working Model. The results obtained using this model compared well to the full-scale tests, accurately predicting the maximum relative displacement at the crack location for the scaled ground motions used in the testing program.
