description: The feeding of protein in line with animal needs from regional sources is a challenge in organic pig fattening. One way to achieve this is the use of clover-grass silage, which so far has received only limited attention. In this working paper an overview and economic analysis of trials of the Thünen Institute of organic farming of feeding clover-grass silage to fattening pigs are presented. On the experimental organic farm in Trenthorst, fattening pigs are housed on straw. They were split into two groups: one group was fed clover-grass silage and a concentrate mix with reduced protein content; the control group was fed a normal mixed ration with typical protein content. The biological performance, rations and feed quantities were evaluated, supplemented with standard data for organic production from the KTBL (Kuratorium für Technik und Bauwesen in der Landwirtschaft). Subsequently, cost calculation of the trial data was carried out and compared with organic standard data without the use of roughage from KTBL. As expected for trials, daily gains, feed conversion, finishing weight, dressing percentage and feed consumption are better for both groups of the Trenthorst fattening trials, compared to the KTBL data. The two trial variants differ only very slightly in performance and costs; both groups are clearly more cost-effective than the KTBL assumptions due to lower concentrate consumption. But the feeding clover-grass silage by hand causes higher labour costs, compared to the control group. Higher prices for the other protein feeds, especially grain legumes, improve the competitiveness of clover-grass feeding, as does lack of an alternative use, if clover-grass is grown on the farm's as part of crop rotation. In summary, feeding clover-grass silage is — also financially — an interesting alternative for fattening pigs organically. For wider use on farms further improvements of labour organisation are needed. In particular, cost-effective mechanisation of feeding silage still needs to be developed.

Causality issue in the heat balance method for calculating the design heating and cooling load
Creators: name: Ghiaus, Christian
Publisher: name: arXiv
Year: 2022
Subjects: subject: Systems and Control (eess.SY)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Heating and cooling load calculation based on dynamic models is widely used in simulation software and it is the method recommended by ASHRAE and CEN. The principle is to make the heat balance for the air volume of a room space considered at uniform temperature and to calculate from this equation the load, i.e. the power needed to obtain the required indoor temperature. The problem is that, by doing so, the physical causality is not respected. If the model is approximated by a piecewise linear dynamical system, this procedure results in an improper transfer function. In order to point out this problem, a method to obtain state space and transfer function models from thermal networks is introduced. Then, the transfer function representation is employed to show that changing the physical causality results in an improper transfer function. The practical consequence is that when the space temperature has a step variation, the calculated load tends to infinity if the simulation time step tends to zero. The issue of causality may be a problem in equation-based simulation software, such as MODELICA, in which the equations do not represent causal relations: a wrong choice of the causality in a balance equation may result in improper transfer functions.

description: This article provides a new approach to analyze the issue of volatility spillovers. In particular, we investigate relationships and transmissions between implied volatilities in corn and soybean markets – two of the most important agricultural commodity markets in the United States. Using weekly average data from 2001 to 2010, we estimate a VAR model with Fourier seasonal components as exogenous variables. Results from this model indicate that volatility spillovers exist from the corn market to the soybean market, but there is no volatility spillover from the soybean market to the corn market. Impulse response functions from this model show that a standard positive shock in the implied volatility of corn has a positive impact on responses of the implied volatility of soybeans. However, responses of the implied volatility of corn to a shock in the soybean market are not significant. To examine the time invariance property of this model, we conduct three bootstrap versions of Chow tests (sample-split, break-point, and Chow forecast). All of these tests suggest significant structural break points in several time periods. To improve the accuracy of our model, we develop a threshold VAR model with four regimes that depend on previous levels of volatilities. Results from the threshold VAR model indicate that when both volatilities are relatively low, volatility spills over from the corn market to the soybean market, but when the implied volatility of soybeans is relatively high, volatility spillover effects reveal an opposite direction. Finally, using futures prices, we estimate a BEKK-GARCH model, which is commonly used to investigate volatility spillover effects. Results from the BEKK model show that volatility spillovers exist between the two markets, which is different from what we have found using implied volatilities.

description: Type-III seesaw is a simple extension of the Standard Model~(SM) with the SU$(2)_\text{L}$ triplet fermion with zero hypercharge. It can explain the origin of the tiny neutrino mass and flavor mixing. After the electroweak symmetry breaking the light neutrino mass is generated by the seesaw mechanism which further ensures the mixings between the light neutrino and heavy neutral lepton mass eigenstates. If the triplet fermions are around the electroweak scale having sizable mixings with the SM sector allowed by the correct gauge symmetry, they can be produced at the high energy colliders leaving a variety of characteristic signatures. Based on a simple and concrete realizations of the model we employ a general parametrization for the neutrino Dirac mass matrix and perform a parameter scan to identify the allowed regions satisfying the experimental constraints from the neutrino oscillation data, the electroweak precision measurements and the lepton-flavor violating processes, respectively considering the normal and inverted neutrino mass hierarchies. These parameter regions can be probed at the different collider experiments.

description: This paper examines the effect that climate has on Avian Influenza outbreak probability. The statistical analysis shows across a broad region the probability of an outbreak declines by 0.22% when the temperature rises 1 Celsius degree and increases by 0.34% when precipitation increases by 1millimeter. These results indicate that the realized climate change of the last 20 years not only has been a factor behind recent HPAI outbreaks, but that climate change is likely to play an even greater role in the future. The statistical results indicate that overall, the risk of an AI outbreak has been increased by 51% under past climate change and 3-4% under future climate change. An economic evaluation shows the increased probability of outbreaks has caused damages of about $107 million in China and $29 million in the United States due to past climate change. In the year of 2011-2030, for countries with a high proportion of chicken production, economic loss could reach $105-$146 million in China and $12-$18 million in the United Sates.

description: This paper examines the uplink user capacity in a two-tier code division multiple access (CDMA) system with hotspot microcells when user terminal power is limited and the wireless channel is finitely-dispersive. A finitely-dispersive channel causes variable fading of the signal power at the output of the RAKE receiver. First, a two-cell system composed of one macrocell and one embedded microcell is studied and analytical methods are developed to estimate the user capacity as a function of a dimensionless parameter that depends on the transmit power constraint and cell radius. Next, novel analytical methods are developed to study the effect of variable fading, both with and without transmit power constraints. Finally, the analytical methods are extended to estimate uplink user capacity for multicell CDMA systems, composed of multiple macrocells and multiple embedded microcells. In all cases, the analysis-based estimates are compared with and confirmed by simulation results.

Specifically, in this work, we will probe (a)symmetry in power between even and odd multipoles of CMB via it's angular power spectrum from Planck 2015 data. Further we also assess any specific preference for mirror parity (a)symmetry, by analysing the power contained in $l+m$=even or odd mode combinations.

Even if the central limit theorem ensures a lognormal distribution of condensation masses at birth, a power-law tail in the distribution arises due to accretion from the ambient cloud, coupled with a non-uniform (exponential) distribution of accretion times.

description: A typical private good is defined by its excludability and rivalry characteristics. Information embodied in a technology might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of this kind of information and its delivery can generate incentives for private participation. This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers’ preferences for rice seed given a set of alternatives. Farmers are considered to be consumers of seed as a production input, preferring one variety over another based on the utility they obtain from its attributes, which depends on their own social and economic characteristics, including whether or not they sell rice. Contingent methods are used to elicit preferences and willingness to pay (WTP) for rice seed. The marginal values of attributes, with and without information about the seed, are estimated with an ordered probit regression. WTP for information is derived from the analysis of WTP for rice seed. The results have implications for the best way to finance research and extension services in the areas of intervention, particularly for new rice varieties.

description: We investigate the effect of strong spin-orbit interaction on the electronic transport through non-magnetic impurities in one-dimensional systems. When a perpendicular magnetic field is applied, the electron spin polarization becomes momentum-dependent and spin-flip scattering appears, to first order in the applied field, in addition to the usual potential scattering. We analyze a situation in which, by tuning the Fermi level and the Rashba coupling, the magnetic field can suppress the potential scattering. This mechanism should give rise to a significant negative magnetoresistance in the limit of large barriers.

description: It has been often suggested that a tangible relation exists between relativistic jets in active galactic nuclei (AGN) and the morphology of their host galaxies. In particular, relativistic jets may commonly be related to merging events. Here we present for the first time a detailed spectroscopic and morphological analysis of a Seyfert galaxy, SDSS J211852.96-073227.5, at $z = 0.26$. This source has previously been classified as a gamma-ray emitting narrow-line Seyfert 1 galaxy. We re-observed it with the 6.5m Clay Telescope and these new, high-quality spectroscopic data have revealed that it is actually an intermediate-type Seyfert galaxy. Furthermore, the results of modelling the $Ks$-band near-infrared images obtained with the 6.5m Baade Telescope indicate that the AGN is hosted by a late-type galaxy in an interacting system, strengthening the suggested connection between galaxy interactions and relativistic jets.

description: Climate change continues to have major impact on crop productivity all over the world. While many researchers have evaluated the possible impact of global warming on crop yields using mainly indirect crop simulation models, there are relatively few direct assessments on the impact of observed climate change on past crop yield and growth. We use a 1979-2000 Chinese crop-specific panel dataset to investigate the climate impact on Chinese wheat yield growth. We find that a 1 percent increase in wheat growing season temperature reduces wheat yields by about 0.3 percent. This negative impact is less severe than those reported in other regions. Rising temperature over the past two decades accounts for a 2.4 percent decline in wheat yields in China while the majority of the wheat yield growth, 75 percent, comes from increased use of physical inputs. We emphasize the necessity of including such major influencing factors as physical inputs into the crop yield-climate function in order to have an accurate estimation of climate impact on crop yields.

description: This paper presents an empirical case study about farmer management of rice genetic resources in two communities of Nepal, drawing on interdisciplinary, participatory research that involved farmers, rice geneticists, and social scientists. The decision-making process of farm households is modelled and estimated in order to provide information for the design of community-based conservation programs. A bivariate model with sample selection treats the simultaneous process of whether farmers decide to plant landraces or modern varieties, and whether the landraces they choose to plant constitute genetic diversity of interest for future crop improvement. Findings show that the two landrace choices are affected by different social and economic factors. The estimation procedure demonstrates that in certain cases, however, the decision processes are interrelated. Policies to promote the conservation of local rice diversity will need to take both processes into account. Fitted equations are then used to compare the likelihood that households targeted for conservation according to one set of conservation criteria also meet other conservation criteria. Households most likely to plant landraces identified as important for crop improvement also grow richer, more spatially diverse rice varieties. In these communities, few policy trade-offs would result from employing one set of criteria instead of the other.

description: We discuss the parameter estimation of the probability of default (PD), the correlation between the obligors, and a phase transition. In our previous work, we studied the problem using the beta-binomial distribution. A non-equilibrium phase transition with an order parameter occurs when the temporal correlation decays by power law. In this article, we adopt the Merton model, which uses an asset correlation as the default correlation, and find that a phase transition occurs when the temporal correlation decays by power law. When the power index is less than one, the PD estimator converges slowly. Thus, it is difficult to estimate PD with limited historical data. Conversely, when the power index is greater than one, the convergence speed is inversely proportional to the number of samples. We investigate the empirical default data history of several rating agencies. The estimated power index is in the slow convergence range when we use long history data. This suggests that PD could have a long memory and that it is difficult to estimate parameters due to slow convergence.

description: Az agrárpolitika kiemelt céljai közé tartozik az agrártámogatások hasznosulásának növelése abban az értelemben, hogy a közvetlen támogatások az eredeti kedvezményezettek, a mezőgazdasági termelők jövedelmi helyzetét javítsák és ne a termékpálya más szereplőinél kössenek ki. A termelők jövedelmére azok a támogatásformák gyakorolják a legkedvezőbb hatást, amelyek a legkevésbé befolyásolják a piaci keresleti-kínálati viszonyokat. Ennek tudatában az elmúlt időszakban az Európai Unió egészében megfigyelhető, hogy a leginkább piactorzító hatású támogatástípusok (a termékkibocsátáson, valamint a változó inputokon alapuló támogatások) aránya lecsökkent. Ezzel szemben a piacot kevésbé befolyásoló, a termeléstől elválasztott (termelési kötelezettséggel nem járó) támogatások részaránya megnőtt. Ez a tendencia Magyarországon is megfigyelhető volt, de a helyzet így sem teljesen kielégítő. Számításaink szerint a 2006. évi közvetlen agrártámogatásoknak mindössze 52%-a gyarapította a mezőgazdasági vállalkozások jövedelmét. A legjobb hasznosulást (62%) a termelésről leválasztott, termelési kötelezettséget nem jelentő SAPS-támogatás tudta felmutatni. --------------------------- Increasing the beneficial effects of agricultural subsidies is one of the main aims of agricultural policy, in the sense of direct subsidies improving the income situation of the original beneficiaries – agricultural producers – rather than going to other actors in the product path. The most beneficial effect on producers’ income is achieved by those forms of subsidy that exert the least influence on the market’s supply and demand relationship. Knowing this, it can be seen that the proportion of subsidy types which most distort the market (subsidies based on product output and variable inputs), has decreased recently throughout the European Union. In contrast, the share of subsidies divorced from production, which influence the market to a lesser degree, has grown. This tendency can also be observed in Hungary, although this does not give a complete picture of the situation. According to our calculations only 52% of direct agricultural subsidies in 2006 actually increased the income of agricultural enterprises. SAPS subsidies, which are divorced from production and include no production obligation, proved to be the most beneficial (62%).

description: In this paper we address the interplay among intention, time, and belief in dynamic environments. The first contribution is a logic for reasoning about intention, time and belief, in which assumptions of intentions are represented by preconditions of intended actions. Intentions and beliefs are coherent as long as these assumptions are not violated, i.e. as long as intended actions can be performed such that their preconditions hold as well. The second contribution is the formalization of what-if scenarios: what happens with intentions and beliefs if a new (possibly conflicting) intention is adopted, or a new fact is learned? An agent is committed to its intended actions as long as its belief-intention database is coherent. We conceptualize intention as commitment toward time and we develop AGM-based postulates for the iterated revision of belief-intention databases, and we prove a Katsuno-Mendelzon-style representation theorem.

Developing and implementing industrial engineering methods for process improvement at Telus communications

Publisher: name: University of British Columbia

description: TELUS, a large Canadian telecommunications company primarily based in Western Canada, provides a full range of telecommunications products and services including data, Internet protocol (IP), voice and mobile wireless services. Every month TELUS processes high volumes of customer orders either for new service or changes in existing service. Within TELUS, the Assignment and Activation group processes all orders and is responsible for changes in the mainframe computers and switches as well as coordination with field service representatives that actually perform physical installations of and changes to customer equipment. The challenges faced by the order processing center include difficulty meeting current throughput and lead time requirements, as well as uncertainty regarding the metrics used for quality and process measurement. Further, increased competition in the telecommunications industry has pressured TELUS to cut costs, resulting a major workforce reduction and widespread process and service reorganization. This thesis describes the development and application of simulation to study the Assignment and Activation group. The data analysis and model development procedure is outlined and results are discussed. Although simulation model development was hindered by difficulties collecting process data, the model building and data analysis process helped identify several opportunities for improvement. The steps required to continue developing the simulation, therefore enabling more detailed questions about the process to be evaluated, are also outlined. Based on the simulation analysis it is recommended that better data collection be implemented to measure key metrics, especially processing time distributions. Putting the uncertainty in the confidence level of the processing estimates aside, this study found that improving the Auto Front End Assignable or the exception rates would have a negligible effect on throughput if the processing times are close to average. In addition, shifting the days out ahead by three days resulted in a 3% increase in on-time completions. Finally in most of the scenarios evaluated, the operator utilization appeared unrealistically high indicating a general staff shortage.

description: Topological electrons in semimetals are usually vulnerable to chemical doping and environment change, which restricts their potential application in future electronic devices. In this paper we report that the type-II Dirac semimetal $\mathbf{VAl_3}$ hosts exceptional, robust topological electrons which can tolerate extreme change of chemical composition. The Dirac electrons remain intact even after a substantial part of V atoms have been replaced in the $\mathbf{V_{1-x}Ti_xAl_3}$ solid solutions. This Dirac semimetal state ends at $x=0.35$ where a Lifshitz transition to $p$-type trivial metal occurs. The V-Al bond is completely broken in this transition as long as the bonding orbitals are fully depopulated by the holes donated from Ti substitution. In other words, the Dirac electrons in $\mathbf{VAl_3}$ are protected by the V-Al bond whose molecular orbital is their bonding gravity center. Our understanding on the interrelations among electron count, chemical bond and electronic properties in topological semimetals suggests a rational approach to search robust, chemical-bond-protected topological materials.

description: We have detected Egyptian blue pigment in the paint layer of the "Birch. Spring" painting by Robert Falk (1907); we have also found this pigment in the paints of the sketch drawn on the canvas back side. This is probably the first discovery of Egyptian blue in a 20th century work of art. We have analyzed a modern commercial Egyptian blue pigment (Kremer) and found it to be suitable as a standard for photoluminescence spectral analysis. The characteristic photoluminescence band of CaCuSi$_4$O$_{10}$ reaches maximum at the wavelength of about 910 nm. The luminescence is efficiently excited by incoherent green or blue light. The study demonstrates that the photoluminescence spectral micro analysis using excitation by incoherent light can be efficiently used for the identification of luminescent pigments in paint layers of artworks.

description: We propose the approach for a lattice investigation of light-cone distribution amplitudes (LCDA) of heavy-light mesons, such as the $B$-meson, using the formalism of parton pseudo-distributions. A basic ingredient of the approach is the study of short-distance behavior of the $B$-meson Ioffe-time distribution amplitude (ITDA), which is a generalization of the $B$-meson LCDA in coordinate space. We construct a reduced ITDA for the $B$-meson, and derive the matching relation between the reduced ITDA and the LCDA. The reduced ITDA is ultraviolet finite, which guarantees that the continuum limit exists on the lattice.

1D action and partition function for the 2D Ising model with boundary magnetic field

description: In this article we obtain some exact results for the 2D Ising model with a general boundary magnetic field and for a finite size system, by an alternative method to that developed by B. McCoy and T.T. Wu. This method is a generalization of ideas from V.N. Plechko presented for the 2D Ising model in zero field, based on the representation of the Ising model using a Grassmann algebra. In this way, a Gaussian 1D action is obtained for a general configuration of the boundary magnetic field. In the special case where the magnetic field is homogeneous, we check that our results are in agreement with McCoy and Wu's previous work, and we also compute the two point correlation functions on the boundary. We use this correlation function to obtain the exact partition function and the free energy in the special case of an inhomogeneous boundary magnetic field.

description: B udapesten és Győrben végzett négyszáz fős, megkérdezésen alapuló ökonometriai és hagyományos statisztikai feldolgozásból származó adatok alapján megállapítható, hogy az ökológiai gazdálkodásból származó termékek iránti városi fogyasztói igényt a megkérdezés helye, a megkérdezettek neme, az iskolai végzettség és a jövedelmi helyzet befolyásolta. Az ökotermék-fogyasztás elősegítése és ösztönzése, az állandó és alkalmi fogyasztók bázisának erősítése, a potenciális vásárlók megnyerése érdekében olyan célirányos ismeretterjesztő marketingprogramok megvalósítása javasolható, amelyek széles körben ismertté teszik az ökotermékek tulajdonságait, megbízhatóságát és minőségét. --------------------------- Data derived from the processing of econometric and traditional statistics based on questions put to 400 people in Budapest and Győr, shows that urban consumer demand for produce from organic farms is influenced by geographical location, gender, educational qualifications and income. In the interests of encouraging organic produce consumption, strengthening the base of regular and occasional consumers, and winning over potential new customers, we recommend implementation of a targeted, awareness-raising marketing programme that informs a wide circle of the characteristics, trustworthiness and quality of organic produce.

description: The increasing pervasive and ubiquitous presence of devices at the edge of the Internet is creating new scenarios for the emergence of novel services and applications. This is particularly true for location- and context-aware services. These services call for new decentralized, self-organizing communication schemes that are able to face issues related to demanding resource consumption constraints, while ensuring efficient locality-based information dissemination and querying. Voronoi-based communication techniques are among the most widely used solutions in this field. However, when used for forwarding messages inside closed areas of the network (called Areas of Interest, AoIs), these solutions generally require a significant overhead in terms of redundant and/or unnecessary communications. This fact negatively impacts both the devices' resource consumption levels, as well as the network bandwidth usage. In order to eliminate all unnecessary communications, in this paper we present the MABRAVO (Multicast Algorithm for Broadcast and Routing over AoIs in Voronoi Overlays) protocol suite. MABRAVO allows to forward information within an AoI in a Voronoi network using only local information, reaching all the devices in the area, and using the lowest possible number of messages, i.e., just one message for each node included in the AoI. The paper presents the mathematical and algorithmic descriptions of MABRAVO, as well as experimental findings of its performance, showing its ability to reduce communication costs to the strictly minimum required.

description: In this talk I present some of the more recent developments within the Covariant Spectator Theory. My focus will be on aspects of the derivation of gauge invariant electromagnetic three-nucleon currents which are consistent with the hadronic equations and with the basic assumptions of this framework. Important dynamical ingredients of the three-nucleon currents are also discussed, namely the three-nucleon bound state vertex function and the two-nucleon interaction model they are derived from.

A New Algebraic Approach to Perturbation Theory

description: An algebraic non-perturbative approach is proposed for the analytical treatment of Schrödinger equations with a potential that can be expressed in terms of an exactly solvable piece with an additional potential. Avoiding disadvantages of standard approaches, new handy recursion formulae with the same simple form both for ground and excited states have been obtained. As an illustration the procedure, well adapted to the use of computer algebra, is successfully applied to quartic anharmonic oscillators by means of very simple algebraic manipulations. The trend of the exact values of the energies is rather well reproduced for a large range of values of the coupling constant (g=0.001-10000).
