description: The growth of the poultry industry in Arkansas has exploded in the past decade. As a result, approximately 1.5 million tons of litter are produced every year. Concerns about possible contamination of ground and surface water from land applications of poultry litter have been raised. This paper compares four policy scenarios in terms of their efficiency and practicality to manage land applications of poultry litter. The results indicate that a litter tax per ton of litter applied could achieve the same level of litter control as that of a land tax on litter applications, but at a lower tax rate.

description: Scalable memories that can match the speeds of superconducting logic circuits have long been desired to enable a superconducting computer. A superconducting loop that includes a Josephson junction can store a flux quantum state in picoseconds. However, the requirement for the loop inductance to create a bi-state hysteresis sets a limit on the minimal area occupied by a single memory cell. Here, we present a miniaturized superconducting memory cell based on a Three-Dimensional (3D) Nb nano-Superconducting QUantum Interference Device (nano-SQUID). The major cell area here fits within an 8*9 μm^2 rectangle with a cross-selected function for memory implementation. The cell shows periodic tunable hysteresis between two neighbouring flux quantum states produced by bias current sweeping because of the large modulation depth of the 3D nano-SQUID (~66%). Furthermore, the measured Current-Phase Relations (CPRs) of nano-SQUIDs are shown to be skewed from a sine function, as predicted by theoretical modelling. The skewness and the critical current of 3D nano-SQUIDs are linearly correlated. It is also found that the hysteresis loop size is in a linear scaling relationship with the CPR skewness using the statistics from characterisation of 26 devices. We show that the CPR skewness range of π/4~3π/4 is equivalent to a large loop inductance in creating a stable bi-state hysteresis for memory implementation. Therefore, the skewed CPR of 3D nano-SQUID enables further superconducting memory cell miniaturization by overcoming the inductance limitation of the loop area.

description: We study the motion of a compressible perfect liquid body in vacuum. This can be thought of as a model for the motion of the ocean or a star. The free surface moves with the velocity of the liquid and the pressure vanishes on the free surface. This leads to a free boundary problem for Euler's equations, where the regularity of the boundary enters to highest order. We prove local existence in Sobolev spaces assuming a "physical condition", related to the fact that the pressure of a fluid has to be positive.

Demand and Price Analysis

description: A model of the domestic demand for eggs was estimated from quarterly data over the period 1987 through 1995, incorporating an index of consumer dietary cholesterol concerns and generic advertising efforts by the American Egg Board and the California Egg Commission. Empirical results indicated that most of the observed change in egg demand could be explained by dietary cholesterol concerns. Simulating the model in a constant elasticity supply framework demonstrated that advertising efforts over the past several years have resulted in net benefits to egg producers largely when considering inelastic supply responses. However, considering trade bias reduces these benefit-cost ratios substantially.

description: U.S. agricultural conservation policy has focused on a range of potential policy instruments centered on voluntary approaches tied into Depression-era commodity programs. Entering the twenty-first century, conservation policy is at a crossroads between more coercive regulatory policies, more costly voluntary programs, and more facilitative market-oriented policies. What are the pitfalls, advantages, disadvantages, and tradeoffs along these paths?

description: A large dam model is an object of study of this paper. The parameters $L^{lower}$ and $L^{upper}$ are its lower and upper levels, $L=L^{upper}-L^{lower}$ is large, and if a current level of water is between these bounds, then the dam is assumed to be in normal state. Passage one or other bound leads to damage. Let $J_1$ $(J_2)$ denote the damage cost of crossing the lower (upper) level. It is assumed that input stream of water is described by a Poisson process, while the output stream is state-dependent (the exact formulation of the problem is given in the paper). Let $L_t$ denote the dam level at time $t$, and let $p_1=\lim_{t\to\infty}\mathbf{P}\{L_t= L^{lower}\}$, $p_2=\lim_{t\to\infty}\mathbf{P}\{L_t> L^{upper}\}$ exist. The long-run average cost $J=p_1J_1+p_2J_2$ is a performance measure. The aim of the paper is to choose the parameter of output stream (exactly specified in the paper) minimizing $J$.

description: Human-Robot Collaboration (HRC) is rapidly replacing the traditional application of robotics in the manufacturing industry. Robots and human operators no longer have to perform their tasks in segregated areas and are capable of working in close vicinity and performing hybrid tasks -- performed partially by humans and by robots. We have presented a methodology in an earlier work [16] to promote and facilitate formally modeling HRC systems, which are notoriously safety-critical. Relying on temporal logic modeling capabilities and automated model checking tools, we built a framework to formally model HRC systems and verify the physical safety of human operator against ISO 10218-2 [10] standard. In order to make our proposed formal verification framework more appealing to safety engineers, whom are usually not very fond of formal modeling and verification techniques, we decided to couple our model checking approach with a 3D simulator that demonstrates the potential hazardous situations to the safety engineers in a more transparent way. This paper reports our co-simulation approach, using Morse simulator [4] and Zot model checker [14].

Subjects: Demand and Price Analysis

description: The Northeast Interstate Dairy Compact has been established to regulate milk prices. Simulation models show impacts on Vermont farms of alternative milk prices and accelerated productivity growth. Enhancing prices (by $0.85/cwt) improves financial performance the most, while impacts of doubling growth in milk production/cow (to 2.6% per year) and setting a price floor (which reduces the standard deviation of the price by 19% and raises prices $0.12/cwt) are substantially smaller. These impacts are inversely related to farm profitability. However, impacts on larger farms are not proportionately larger than those on smaller farms. Reducing price variability has smaller impacts than the $0.12/cwt price increase.
Generalized MDL approach for data summarization
Creators: name: Zhou, Xiaodong
Publisher: name: University of British Columbia
Year: 2009

description: There are many applications that identify some data of interest. Usually, such applications just return a set of records that satisfy the criteria applied. However, such results cannot provide enough information for the user. A concise description is more preferable than the individual data. Minimum Description Length (MDL) is a well-known approach to handle such problems. In this thesis, we extend the MDL principle to the Generalized MDL (GMDL) principle by including some "do not care" data. We apply the MDL and GMDL principles to solve the problem of data summarization both in the spatial case and in the hierarchical case. For the spatial case, we improve one current top-down algorithm for high-dimensional data. We also study the GMDL problem for the hierarchical case and find that there exists a unique, non-redundant, and bluemaximal MDL covering. We propose MDL-Tree and GMDL-Tree algorithms to find MDL covering and GMDL covering respectively in the hierarchical case. The experimental results show that GMDL coverings have a much shorter description than MDL covering in the hierarchical case.

description: Robots are soon going to be deployed in non-industrial environments. Before society can take such a step, it is necessary to endow complex robotic systems with mechanisms that make them reliable enough to operate in situations where the human factor is predominant. This calls for the development of robotic frameworks that can soundly guarantee that a collection of properties are verified at all times during operation. While developing a mission plan, robots should take into account factors such as human physiology. In this paper, we present an example of how a robotic application that involves human interaction can be modeled through hybrid automata, and analyzed by using statistical model-checking. We exploit statistical techniques to determine the probability with which some properties are verified, thus easing the state-space explosion problem. The analysis is performed using the Uppaal tool. In addition, we used Uppaal to run simulations that allowed us to show non-trivial time dynamics that describe the behavior of the real system, including human-related variables. Overall, this process allows developers to gain useful insights into their application and to make decisions about how to improve it to balance efficiency and user satisfaction.

title: Modeling the Contagion Effect of Foreclosures Within the Real Estate Market by Use of Agent-Based Modeling and Simulation
Creators: name: Gangel, Marshall William
Publisher: name: Old Dominion University Libraries
Year: 2011

description: Over the last several years, the US financial and real estate markets have experienced a significant recession. During this downturn, the number of real estate foreclosures rose drastically. Recent studies have empirically demonstrated a reduction in real estate values due to foreclosures. The observed reduction in the average value of real estate properties has been labeled the foreclosure contagion effect. The foreclosure contagion effect impacts healthy neighboring properties that surround the foreclosed property as a function of time and distance.

This study uses an agent-based modeling and simulation (ABMS} approach to explore the contagion effect of foreclosures. For this research, the agents are defined as individual properties that are given rules and attributes which instruct them when and how to act within their environment. The agents use their current state, the environment, and the actions of other property agents as input to their rule sets.

The simulation is studied via parametric analysis to understand the relationships between model variables and their effect on the system. Several emergent behaviors are discovered during the analysis of the simulation results. These emergent behaviors illustrate the relationships between the average property values, foreclosure contagion discount, amount of time foreclosures remain on the market, and interest rates. The findings of this research demonstrate that ABMS is a valid method to study the contagion effect of foreclosures within the real estate market.

description: The atmospheric structure of Mira variables is considerably influenced by pulsation. Molecular absorption lines in the near-infrared (NIR), especially second overtone CO lines, show therefore a characteristic behaviour in time-series of high-resolution spectra. We computed synthetic CO line profiles based on a new dynamic model atmosphere and derived radial velocities (RVs) from the Doppler shifted lines. For the first time, we could quantitatively reproduce observations of the very typical, discontinuous RV curves.

description: Robots are often so complex that one person may not know all the ins and outs of the system. Inheriting software and hardware infrastructure with limited documentation and/or practical robot experience presents a costly challenge for an engineer or researcher. The choice is to either re-build existing systems, or invest in learning the existing framework. No matter the choice, a reliable system which produces expected outcomes is necessary, and while rebuilding may at first appear easier than learning the system, future users will be faced with the same choice. This paper provides a method to allow for increased documentation of the robotic system, which in turn can be used to contribute in overall robot reliability. To do this we propose the identification of a robot's core behaviors for use in Capability Analysis Tables (CATs). CATs are a form of tabular documentation that connect the hardware and software inputs and outputs to the robot's core behaviors. Unlike existing methods, CATs are flexible, easy to build, and understandable by non-expert robot users. We demonstrate this documentation method with an experimental example using an Unmanned Aerial Vehicle (UAV).

DNA properties investigated by dynamic force microscopy

description: In this work, we show that by varying the experimental conditions, the driving amplitude, a dynamic force microscope allows DNA properties to be selectively imaged. The substrate on which the DNA is fixed is a silica surface grafted with silanes molecules ended with amine groups. Use of small oscillation amplitudes favors the attractive interaction between the tip and the sample, while use of large amplitudes renders the contribution of the attractive interaction negligible. Particularly, at small amplitudes, the images show that the attractive interaction is strongly enhanced along the DNA. This enhancement is found to be amenable with a model considering a narrow strip of randomly oriented dipoles on each side of the molecule. This work should provide new insights on the DNA interaction and conformational changes with localized charges.

description: In this paper, by defining off-shell amplitudes as off-shell CHY integrals, and redefining the longitudinal operator, we demonstrate that the differential operators which link on-shell amplitudes for a variety of theories together, also link off-shell amplitudes in the similar manner. Based on the algebraic property of the differential operator, we also generalize three relations among color-ordered on-shell amplitudes, including the color-ordered reversed relation, the photon decoupling relation, the Kleiss-Kuijf relation, to off-shell ones. The off-shell CHY integrals are chosen to be in the double-cover framework, thus, as a by product, our result also provides a verification for the double-cover construction.

description: This paper develops an integrated model for analysing regional economic development and structural change in agriculture. The input-output method allows the detailed description of a regional economy. Based on this description, regional growth pole sectors can be identified that are potential leverage points for growth oriented development strategies. Dynamic simulation tests the long term effects of such a development strategy. Model results show that external demand is the main driving force behind regional economic growth. However, development strategies for lagging rural areas have to be coupled to development strategies for regional centres. Only if the rural areas surrounding regional centres become an important asset for the development of these centres can rural areas be stabilised.

description: Given the complexity of real-world, unstructured domains, it is often impossible or impractical to design models that include every feature needed to handle all possible scenarios that an autonomous system may encounter. For an autonomous system to be reliable in such domains, it should have the ability to improve its competence online. In this paper, we propose a method for improving the competence of a system over the course of its deployment. We specifically focus on a class of semi-autonomous systems known as competence-aware systems that model their own competence -- the optimal extent of autonomy to use in any given situation -- and learn this competence over time from feedback received through interactions with a human authority. Our method exploits such feedback to identify important state features missing from the system's initial model, and incorporates them into its state representation. The result is an agent that better predicts human involvement, leading to improvements in its competence and reliability, and as a result, its overall performance.

description: The groundwater resource, the drinking water areas and the surface water quality can be protected by measures, e.g. by reductions of pesticide and nutrient applications, conversion of arable land to grasslands or forests etc. The objective of the paper is to estimate the benefits of groundwater protection by the valuation method choice experiments. This method allows for separate estimation and comparison of the different attributes connected to groundwater protection i.e. the effects on drinking water and surface water quality as compared to the benefits from cleaning and treatment of polluted drinking water to make it suitable for drinking water consumption. The results indicate that the benefits are significant, and that the willingness to pay for protection of the groundwater exceeds that from purification.

description: Occurrence of cattle disease known as Bovine spongiform encephalopathy (BSE) has caused great fluctuations in production and consumption of beef meat in the European Union. Croatia does not have enough cattle to meet demands of domestic market. However, there is not one case of BSE in cattle reported in Croatia to date. This fact can be used as an advantage on the beef meat market, presupposing that Croatia has implemented quality programs to increase number of cattle. Research results show that 70% of examinees consume beef at least once a week up to several times a month, and 70.5% have not reduced beef consumption after the disease occurred.

Moreover, two explicit examples are given for which timelike and null geodesics can never be closed.

description: An agricultural sector model for ex ante policy analysis is developed and applied for the simulation of alternative implementations of the Agenda 2000 Mid Term Review (MTR). The model uses an adapted version of Positive Mathematical Programming allowing simultaneous modelling of individual farms. It applies farm level calibrated quadratic cost functions to a sample of the Farm Accountancy Data Network to account for the large variability among farms. The farm level approach is important for the evaluation of the MTR, because MTR policy instruments rely on differences between farms. Extending the model for coping with the MTR implies three important elements: i) modelling the activation of decoupled direct payment entitlements, ii) simulating the modulation and iii) the transfers of direct payment entitlements. While most MTR analysis's focus on the first element, the current paper also tries to deal with the two last elements of the MTR.

description: This paper describes exploratory experiments to validate the possibility of programming autonomous robots using an agent-oriented programming language. Proper perception of the environment, by means of various types of sensors, and timely reaction to external events, by means of effective actuators, are essential to provide robots with a sufficient level of autonomy. The agent-oriented programming paradigm is relevant with this respect because it offers language-level abstractions to process events and to command actuators. A recent agent-oriented programming language called Jadescript is presented in this paper together with its new features specifically designed to handle events. Exploratory experiments on a simple case-study application are presented to show the validity of the proposed approach and to exemplify the use of the language to program autonomous robots.

Provided that inducement hypothesis implies a long run relationship an error correction model (ECM) is estimated to separate long-run effect, that is technological innovation, from short-run effects, that is factors substitution. The results corroborate the induced innovation hypothesis and underline the importance of private R&D in Italian agriculture.

description: We use recent observations of type Ia Supernova (SN Ia) rates to derive, on robust empirical grounds, the distribution of the delay time (DTD) between the formation of the progenitor star and its explosion as a SN. Our analysis finds: i) delay times as long as 3-4 Gyr, derived from observations of SNe Ia at high redshift, cannot reproduce the dependence of the SN Ia rate on the colors and on the radio-luminosity of the parent galaxies, as observed in the local Universe; ii) the comparison between observed SN rates and a grid of theoretical "single-population" DTDs shows that only a few of them are possibly consistent with observations. The most successful models are all predicting a peak of SN explosions soon after star formation and an extended tail in the DTD, and can reproduce the data but only at a modest statistical confidence level; iii) present data are best matched by a bimodal DTD, in which about 50% of type Ia SNe (dubbed "prompt" SN Ia) explode soon after their stellar birth, in a time of the order of 10^8 years, while the remaining 50% ("tardy" SN Ia) have a much wider distribution, well described by an exponential function with a decay time of about 3 Gyr. This fact, coupled with the well established bimodal distribution of the decay rate, suggests the existence of two classes of progenitors. We discuss the cosmological implications of this result and make simple predictions. [Abridged]

description: This paper is an extraction of some results achieved in a comprehensive study of Russia's transition in its regional as well as sectoral dimension. Thereby, the transition process between 1993 - 2000 has been approximated by aggregated developments of productivity, technical change, and technical efficiency which all have been calculated by a Stochastic Frontier Analysis (SFA). The obtained results have been analyzed with respect to any institutional circumstances in a second analytical step. Based on that, in a third step, some political call for actions have been specified as well as addressed according to regional/federal responsibility. The study has shown a notable heterogeneity within the considered regional as well as sectoral transition paths. Occasionally, the individual trends even diverge and provide, however, a growing economic polarization among Russia's regions. Background of these trends are, above all, spatial divergent institutional conditions caused by various reform implementations and/or reform strictness. Hence, the crucial call for political action had to be addressed regionally. At federal level, just coordinating and flanking measures have been mentioned. Altogether it can be summarized: The necessary pre-conditions for a successful transition in Russia seem to be given. But there is apparently a need in some regions for an adequate individual adjustment as well as, sometimes, for a sustainable stimulus in order to trigger a change. Hence, the particular embodiment of the regional transition path, the political initiative, and, therefore, any success on Russia's way from a 'planned towards a market economy' are incumbent on the regions. Admittedly, those have to be aware of own potentials. The regions should develop their individual chances actively and, however, try to turn specialties into benefits. Since this will be successful, it can be a source of substantial growth at regional as well as at federal level.
Interactive directed exploration for mobile robots

description: A mobile robot is often required to function intelligently within a dynamic environment with only partial knowledge of that environment. The robot is usually equipped with an exploration module that allows it to increase its knowledge of its surroundings by exploring unknown regions but it is often difficult for the robot to decide which are the most interesting places to visit first. In our experience the robot spends too much of its time exploring uninteresting regions. Existing robot control systems allow a user to intervene using a GUI program accepting input through a mouse and keyboard. In this thesis we improve on the method of human-robot interaction by building a system for guiding the robot during the exploration phase, using the more natural means of speech and vision. To build a robust system we chose to implement a behavior-based control architecture. The entire system consists of a large number of different behaviors (software modules) running on a number of different computers connected over a LAN. There are distinct behaviors for speech recognition, user finding, speech synthesis, sound localization, safe navigation, map building and high level reasoning. Using this interface, a person can get the robot's attention by calling its name. He can then direct the robot to a location to explore using a combination of verbal commands and hand gestures. We will show how the developed system will provide us with a platform for future research in human-robot interaction and behavior-based robot controllers.

description: Milgram's reality-virtuality continuum applies to interaction in the physical space dimension, going from real to virtual. However, interaction has a social dimension as well, that can go from real to artificial depending on the companion with whom the user interacts. In this paper we present our vision of the Reality-Artificiality bidimensional Continuum (RAC), we identify some challenges in its design and development and we discuss how reliable interactions might be supported inside RAC.

description: This paper analyzes the strategic effects of national regulatory decisions on labeling of GM products and identifies the determinants of the noncooperative Nash equilibrium labeling regimes in a small number of producing countries that have adopted the GM technology. Analytical results show that the equilibrium labeling regimes depend on (i) the distribution of consumer preferences and the level of consumer aversion to GM products; (ii) the segregation and labeling costs in these countries; (iii) the relative productive efficiency and the cost effectiveness of the GM technology; (iv) the structure of the trading sector; (v) the market power of the life science companies; and (vi) the strength of intellectual property rights in these countries.

description: This paper presents the results of a large-scale study in the Spanish F&DI aimed to identify the motivators, perceived costs, and benefits of implementing ISO 9000 standards. Results indicate the increasing importance of ISO 9000 standards as a strategic tool in the Spanish F&DI with an increasing number of F&D companies seeking ISO 9000 certification. Despite being a recent strategic option among Spanish F&D companies latest figures show a total of 1,754 firms being ISO 9000 certified (a significant increased from a total of 4 firms in 1993)

description: An analytical framework is proposed for analysis of environmental good production by farmers in the case of price uncertainty. Environmental good production contracted by means of agri-environmental agreements is treated as a risk less option in the farmer's production activities portfolio. Efficient frontiers were generated using mathematical programming farm level models of suckler cow farms in Monts du Cantal, in France. It was demonstrated that for a DARA risk averse farmer: 1) the agreement payment level is not without impact on the farming intensity on parcels not subscribed under the corresponding argi-environmental programme, 2) a lump sum payment matters under uncertainty, 3) the overall impact of the lump sum payment on environmental good production depends on the type of jointness in production of agricultural and environmental goods, and on the level of uncertainty.

description: Long-term autonomy requires autonomous systems to adapt as their capabilities no longer perform as expected. To achieve this, a system must first be capable of detecting such changes. In this position paper, we describe a system architecture for BDI autonomous agents capable of adapting to changes in a dynamic environment and outline the required research. Specifically, we describe an agent-maintained self-model with accompanying theories of durative actions and learning new action descriptions in BDI systems.

description: The reliable operation of micro and nanomechanical devices necessitates a thorough knowledge of the water film thickness present on the surfaces of these devices with an accuracy in the nm range. In this work, the thickness of an ultra-thin water layer was measured by distance tunnelling spectroscopy and distance dynamic force spectroscopy during desorption in an ultra-high vacuum system, from about 2.5 nm up to complete desorption at 1E-8 mbar. The tunnelling current as well as the amplitude of vibration and the normal force were detected as a function of the probe-sample distance. In these experiments, a direct conversion of the results of both methods is possible. From the standpoint of surface science, taking the state-of-the-art concerning adsorbates on surfaces into consideration, dynamic force spectroscopy provides the most accurate values. The previously reported tunnelling spectroscopy, requiring the application of significantly high voltages, generally leads to values that are 25 times higher than values determined by dynamic force spectroscopy.
