description: The Neptunian satellite system is unusual, comprising Triton, a large ($\sim2700$ km) moon on a close-in, circular, yet retrograde orbit, flanked by Nereid, the largest irregular satellite ($\sim$300 km) on a highly eccentric orbit. Capture origins have been previously suggested for both moons. Here we explore an alternative in-situ formation model where the two satellites accreted in the circum-Neptunian disk and are imparted irregular and eccentric orbits by a deep planetary encounter with an ice giant (IG), like that predicted in the Nice scenario of early solar system development. We use $N$-body simulations of an IG approaching Neptune to 20 Neptunian radi ($R_\mathrm{Nep}$), through a belt of circular prograde regular satellites at 10-30 $R_\mathrm{Nep}$. We find that half of these primordial satellites remain bound to Neptune and that 0.4-3\% are scattered directly onto wide and eccentric orbits resembling that of Nereid. With better matches to the observed orbit, our model has a success rate comparable to or higher than capture of large Nereid-sized irregular satellites from heliocentric orbit. At the same time, the IG encounter injects a large primordial moon onto a retrograde orbit with specific angular momentum similar to Triton's in 0.3-3\% of our runs. While less efficient than capture scenarios (Agnor & Hamilton 2006), our model does indicate that an in-situ origin for Triton is dynamically possible. We also simulate the post-encounter collisional and tidal orbital evolution of Triton analogue satellites and find they are decoupled from Nereid on timescales of $\sim$$10^4$ years, in agreement with Cuk & Gladman (2005).

description: This study was undertaken with the primary purpose of assessing the welfare gain to local residents resulting from olive trees. A secondary but important aim was to underline the multifunctional role of olive farming. In fact, we know that olive plantation has potentially socially benefits. In particular, it has potentially a lot of positive social effects in rural areas depending on plantation characteristics and farming practices. Therefore, the first section of this paper reviews the main features connected to the multifunctional role of olive farming. Multifunctional role of olive farming is well known in the EU, but it is still needed the institutional intervention in favour of farmers, due to the structural difficulties of olive production sector. Later sections concentrate on a survey carried out in order to estimate the economic value of the rural landscape, focusing in particular on olive trees in a hill region between Italy and Slovenia. From the conducted survey we gauged citizens’ WTP to introduce olive trees in the landscape. Survey data was collected by means of questionnaires. We applied the Contingent Valuation Method (CVM) in order to assess the citizens’ Willingness To Pay (WTP) for specific rural landscape features. The paper ends with some conclusions about the positive results obtained in olive plantation valuation questions.

description: The chemical enrichment of the Universe at all scales is related to stellar winds and explosive supernovae phenomena. Metals produced by stars and later spread at the mega-parsec scale through the intra-cluster medium (ICM) become a fossil record of the chemical enrichment of the Universe and of the dynamical and feedback mechanisms determining their circulation. As demonstrated by the results of the soft X-ray spectrometer onboard Hitomi, high resolution X-ray spectroscopy is the path to to differentiate among the models that consider different metal production mechanisms, predict the outcoming yields, and are function of the nature, mass, and/or initial metallicity of their stellar progenitor. Transformational results shall be achieved through improvements in the energy resolution and effective area of X-ray observatories to detect rare metals (e.g. Na, Al) and constrain yet uncertain abundances (e.g. C, Ne, Ca, Ni). The X-ray Integral Field Unit (X-IFU) instrument onboard the next-generation European X-ray observatory Athena is expected to deliver such breakthroughs. Starting from 100 ks of synthetic observations of 12 abundance ratios in the ICM of four simulated clusters, we demonstrate that the X-IFU will be capable of recovering the input chemical enrichment models at both low ($z = 0.1$) and high ($z = 1$) redshifts, while statistically excluding more than 99.5% of all the other tested combinations of models. By fixing the enrichment models which provide the best fit to the simulated data, we also show that the X-IFU will constrain the slope of the stellar initial mass function within $\sim$12%. These constraints will be key ingredients in our understanding of the chemical enrichment of the Universe and its evolution.

description: Motivated by the large rates of $B\rightarrow (χ_{c0}, χ_{c2}, h_c)K$ decays observed by the $BABAR$ and Belle collaborations, we investigate the nonfactorizable contributions to these factorization-forbidden decays, which can occur through a gluon exchange between the $c\bar c$ system and the spectator quark. Our numerical results demonstrate that the spectator contributions are capable of producing a large branching ratio consistent with the experiments. As a by-product, we also study the Cabibbo-suppressed decays, such as $B\rightarrow (χ_{c0}, χ_{c2}, h_c)π$ and the U-spin-related $B_s$ decay, which have so far received less theoretical and experimental attention. The calculated branching ratios reach the order of $10^{-6}$, which in within the scope of the Belle-II and LHCb experiments. Further, the $CP$-asymmetry parameters are also calculated for these decays. The obtained results are compared with the available experimental data and numbers from other predictions. We also investigate the sources of theoretical uncertainties in our calculation.

description: Through the analysis of Mariano Campo’s (1892-1976) published works and thanks to further insights offered by some unpublished manuscripts, the profile of a philosopher is outlined, whose main interest, throughout his academic and research activity, has been aesthetics. More specifically, Campo has focused on the centrality of feelings to human aesthetic experience: it is through feeling that we experience a transfiguration of reality, which happens paradigmatically when, in front of an artwork, we appreciate it as an integral whole, a totality.

description: We have found evidence for the presence of two distinct ancient stellar components (both geq 10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO Wide Field Imager (WFI) in conjunction with the VLT/FLAMES spectrograph to study the properties of the resolved stellar population of Sculptor out to and beyond the tidal radius. We find that two components are discernible in the spatial distribution of Horizontal Branch stars in our imaging, and in the [Fe/H] and v_hel distributions for our large sample of spectroscopic measurements. They can be generally described as a ``metal-poor'' component ([Fe/H]< -1.7) and a ``metal-rich'' component ([Fe/H]> -1.7). The metal-poor stars are more spatially extended than the metal-rich stars, and they also appear to be kinematically distinct. These results provide an important insight into the formation processes of small systems in the early universe and the conditions found there. Even this simplest of galaxies appears to have had a surprisingly complex early evolution.

description: The recent paper by Lee and Lee (2004) may strongly leave the impression that astronomers have established that the rotation curves of spiral galaxies are flat. We show that the old paradigm of Flat Rotation Curves lacks, today, any observational support and following it at face value leads to intrinsically flawed alternatives to the Standard Dark Matter Scenario. On the other side, we claim that the rich systematics of spiral galaxy rotation curves, that reveals, in the standard Newtonian Gravity framework, the phenomenon of dark matter, in alternative scenarios, works as a unique benchmark.

title: Mathematical modelling of under-ice melt ponds and their impact on the thermohaline interaction between sea ice and the oceanic mixed layer
Creators: name: Smith, Naomi
Publisher: name: University of Reading
Year: 2019

description: Melt water from the surface of Arctic sea ice fills hollows in the topography of the ice, forming pools of sea water that can cover up to 50% of the surface of the ice in the summer months. Since ice is a porous medium, water can percolate down from these melt ponds to the base of the sea ice, where it gathers in pools between the relatively cold, saline ocean water and the sea ice. These ponds are known as under-ice melt ponds. Freezing can occur at the interface between the under-ice melt pond and the oceanic mixed-layer, forming a sheet of ice called a false bottom. False bottoms insulate the true base of the sea ice from the ocean and their formation is a significant mechanism of Arctic sea ice summer growth. By changing the rate of basal ablation, under-ice melt ponds alter the fresh water and salt fluxes from the sea ice into the ocean. Here, we evaluate the impact of under-ice melt ponds and false bottoms on the mass balance of the sea ice and its thermohaline interaction with the oceanic mixed layer below. We present a one-dimensional thermodynamic model of the evolution of under-ice melt ponds and false bottoms, with which we found that their development insulates the sea ice above them, increasing ice thickness. We couple this to a simplified ocean mixed layer model and found that the ablation of false bottoms rapidly transfers stored fresh water to the mixed layer. Our model indicates that under-ice melt ponds could lead to sea ice several tens of centimetres thicker if they form annually, and that false bottom ablation could lead to a sudden Arctic ocean mixed layer freshening and a resulting shallowing of the order of ten metres in areas of high under-ice melt pond fraction.

description: In this article we treat the problem of nonpoint source pollution as a problem of moral hazard in group. To solve this kind of problem we consider a group performance based tax coupled to tradable permits market. The tax is activated if the group fails to meet the ambient standard. So the role of the tax is to provide an incitation to ensure that the agents provide the abatement level necessary to achieve the standard. The role of the tradable permits market is to distribute effectively this abatement level through the price of the permits which rises with the exchange of the permits.
Classical Theta Lifts for Higher Metaplectic Covering Group

Subjects: subject: Representation Theory (math.RT)

description: The classical theta correspondence establishes a relationship between automorphic representations on special orthogonal groups and automorphic representations on symplectic groups or their double covers. This correspondence is achieved by using as integral kernel a theta series on the metaplectic double cover of a symplectic group that is constructed from the Weil representation. There is also an analogous local correspondence. In this work we present an extension of the classical theta correspondence to higher degree metaplectic covers of symplectic and special orthogonal groups. The key issue here is that for higher degree covers there is no analogue of the Weil representation, and additional ingredients are needed. Our work reflects a broader paradigm: constructions in automorphic forms that work for algebraic groups or their double covers should often extend to higher degree metaplectic covers.

description: Technical and scale efficiencies are estimated for organic and non-organic dairy farms in the United States using an input distance function approach. A multinomial logit analysis is used to categorize the farms by technology. Large conventional farms outperformed smaller farms in most technology / organic / non-organic categories. There was high variability in net returns among the organics so that they did not differ significantly from the large conventional farms. The largest conventional non-organic operations and conventional organic operations tended to have the higher technical efficiencies.

Simultaneous Production of Disk and Lobes: A Single-Wind MHD Model for the Eta Carinae Nebula

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: The luminous blue variable Eta Carinae is surrounded by a complex and highly structured nebula of ejected material. The best-studied and axisymmetric components of this outflow consist of bipolar lobes (the ``homunculus'') and an equatorial ``skirt.'' Recent proper motion measurements suggest that the skirt was ejected at the same time as the lobes, contrary to the assumptions of all current theoretical models for the formation of the nebula (which use the skirt to collimate stellar winds into lobes). We present a magnetohydrodynamic (MHD) stellar wind model that produces an outflowing disk and bipolar lobes in a single, steady-state wind. The basic model consists of a wind from a rotating star with a rotation-axis-aligned dipole magnetic field. The azimuthal component of the magnetic field, generated by stellar rotation, compresses the wind toward the equator and also toward the rotation axis, simultaneously producing an outflowing disk and jet. We use numerical MHD simulations to study the wind for various amounts of stellar rotation and to show a range of wind morphologies. In order to produce wide angle lobes similar to the homunculus (which have roughly a 30 degree opening angle), a high-speed polar wind (with enhanced energy density) from the star is also required. In that case, the structure of the wind bears a remarkable resemblance to the skirt plus homunculus morphology of the Eta Car nebulae, and a significant fraction of the stellar angular momentum is carried away by the wind. Although the model assumes a steady-state wind (rather than an eruption) and thermal wind driving (rather than radiation pressure), the structure of the wind is encouraging.

description: We describe a scheme for finding quantum critical points based on studies of a non-equilibrium susceptibility during finite-rate quenches taking the system from one phase to another. We assume that two such quenches are performed in opposite directions, and argue that they lead to formation of peaks of a non-equilibrium susceptibility on opposite sides of a critical point. Its position is then narrowed to the interval marked off by these values of the parameter driving the transition, at which the peaks are observed. Universal scaling with the quench time of precision of such an estimation is derived and verified in two exactly solvable models. Experimental relevance of these results is expected.

description: A multiple regression was performed on 37 years of data to determine the impact of raising the tobacco tax on cigarettes by $.24 per pack on cigarette sales in Mississippi. The t-statistic for the slope was significant at the .05 critical alpha level, t(29) =1.69 and p=.05. Thus, we conclude that there is a positive significant relationship between taxes and sales volume. Further, about 91 of the variability in sales volume could be explained by the demand model.

description: Anion-π interactions play an important role in supramolecular chemistry. The aim of this work is to explore the effect of H-bonding between s-Triazine and separated molecules (HF)n(HCl)3-n on the strength of anion-π interaction in X−–s-Triazine–(HF)n(HCl)3-n (X− = F–, Cl– and CN–) complexes. The M06-2X/6-311++G(d,p) binding energies (BEs) were corrected by using B2PLYP, mPW2PLYP, M06-2X-GD3 and B2PLYP-GD3 functionals. The molecular electrostatic potential (MESP) analysis revealed that involving multiple binding sites in s-Triazine (TA) through N···H H-bonding can enhance the MESP value over the ring centre of TA so that for H-bonding complexes containing HF is greater than those of HCl. The BE results revealed that the stability of X−–TA–(HF)n(HCl)3-n anion-π complexes in each series increases as the number of HF involved in H-bonding increases. The results showed that the complexes owning F– anion with higher interaction energies display the strong cooperativity effects in the ternary systems. B2PLYP functional showed stronger intramolecular dispersion effects than M06-2X one. Besides, a correlation was found between BE, MESP, bond distances, natural bond orbitals (NBO) and atoms in molecules (AIM) data.

description: Individuals and households reveal their willingness to pay to enjoy environmental and natural resource services by engaging in outdoor recreation activities. The state of Alabama and the Black-Belt region possess significant recreational fishing resources whose qualities could be improved through public and private management innovations. To measure the value of such interventions, a baseline estimate of recreational fishing demand and potential for increasing the demand by on-site improvements needs to established. Using direct mail survey, count data obtained on individual angler characteristics, expenditures on fishing equipment, and destinations and expenditures on time and travel for each trip taken. In addition, the kinds and quantities of fish that anglers sought on each trip were obtained. This paper employs a full a full economic analysis based on recreation demand models—a.k.a. Travel Cost models (TCM). The travel costs’ Negative Binomial regression reveals that the average number of fishing days demanded is 33.17days, while other demographic and site characteristics have varying effects on the number of fishing days demanded.

The objective was to discover the attributes that marketing companies prefer for the naturally produced cattle they purchase, and to elicit the price premiums being offered for cattle that possess these attributes. Results of a phone survey of companies that purchase natural cattle show that 27 out of 32 companies report their willingness to pay a premium of $5.95/cwt for cattle that have never received antibiotics, ionophores, hormones or animal by-products.

description: In this paper we present results from an IRAM Plateau de Bure millimetre-wave Interferometer (PdBI) survey for CO emission towards radio-detected submillimetre galaxies (SMGs) with known optical and near-infrared spectroscopic redshifts. Five sources in the redshift range z~1-3.5 were detected, nearly doubling the number of SMGs detected in CO. We summarise the properties of all 12 CO-detected SMGs, as well as 6 sources not detected in CO by our survey, and use this sample to explore the bulk physical properties of the SMG population as a whole. The median CO line luminosity of the SMGs is = (3.8 +- 2.0) x 10^10 K km/s pc^2. Using a CO-to-H_2 conversion factor appropriate for starburst galaxies, this corresponds to a molecular gas mass = (3.0 +- 1.6) x 10^10 Msun within a ~2kpc radius, about four times greater than the most luminous local ultraluminous infrared galaxies (ULIRGs) but comparable to that of the most extreme high-redshift radio galaxies and QSOs. The median CO fwhm linewidth is broad, = 780 +- 320 km/s, and the SMGs often have double peaked line profiles, indicative of either a merger or a disk. From their median gas reservoirs (~3 x 10^10 Msun) and star-formation rates (>700 Msun/yr) we estimate a lower limit on the typical gas-depletion time scale of >40Myr in SMGs. This is marginally below the typical age expected for the starbursts in SMGs, and suggests that negative feedback processes may play an important role in prolonging the gas consumption time scale. We find a statistically-significant correlation between the far-infrared and CO luminosities of the SMGs which extends the observed correlation for local ULIRGs to higher luminosities and higher redshifts.

description: The construction of atomically-precise carbon nanostructures holds promise for developing novel materials for scientific study and nanotechnology applications. Here we show that graphene origami is an efficient way to convert graphene into atomically-precise, complex, and novel nanostructures. By scanning-tunneling-microscope manipulation at low temperature, we repeatedly fold and unfold graphene nanoislands (GNIs) along arbitrarily chosen direction. A bilayer graphene stack featuring a tunable twist angle and a tubular edge connection between the layers are formed. Folding single-crystal GNIs creates tubular edges with specified chirality and one-dimensional electronic features similar to those of carbon nanotubes, while folding bi-crystal GNIs creates well-defined intramolecular junctions. Both origami structural models and electronic band structures were computed to complement analysis of the experimental results. The present atomically-precise graphene origami provides a platform for constructing novel carbon nanostructures with engineered quantum properties and ultimately quantum machines.
Fausto A. Torrefranca e l’estetica musicale italiana d’inizio Novecento

description: At the beginning of the XX century music’s aesthetic is not an autonomous discipline with defined borders. Scholars dealing with it are neither philosophers in the strict sense nor merely historians or critics of music. In this paper, I wonder about the possibility of finding the traces of the first Italian aesthetics of music among the folds of a composite and ongoing reflection and through the study of some generally-considered musicological production also having some philosophical profile. Along this path, some figures of particular interest emerge such as that of Fausto Acanfora Torrefranca, a “non-aligned” intellectual, who firmly tried to give musical studies an aesthetic-philosophical basis, on the one hand, and a much needed rigor in the early twentieth century Italy on the other.

description: Protons are increasingly used as a surrogate for neutrons to study radiation damage of engineering alloys used in the core of a nuclear reactor, enabling high fluences in comparatively short times. However, the accelerated damage rate of protons is usually compensated by an increased irradiation temperature to assist diffusion. To better understand dose rate effects on microstructure evolution during radiation damage, recrystallized Low-Sn ZIRLO and Zircaloy-2 were proton-irradiated to 0.15 dpa at 320°C using nominal dose rates of 1.3, 2.5, and 5.2 × 10-5 dpa/s. Depth profiling using microbeam synchrotron XRD was conducted across the 30 µm deep irradiated regions for line profile analysis, enabling dislocation line density determination. We found no significant difference in dislocation density among the different dose rates for Zircaloy-2 while Low-Sn ZIRLO displayed dose rate sensitive microstructural evolution. However, Low-Sn ZIRLO exhibited a significantly lower overall dislocation density compared to Zircaloy-2 samples at all dose rates. (S)TEM analysis of the samples showed clear  loop alignment in Zircaloy-2, while this was less pronounced in Low-Sn ZIRLO. APT analysis conducted on Low-Sn ZIRLO specimens showed the early onset of irradiation induced nanoclusters of Nb, where the clusters were observed to be comparatively smaller in the sample exposed to high dose rate irradiation. Overall, the integration of different techniques has provided a more comprehensive understanding of the early-stage damage evolution under differing damage accumulation rates.

description: Producers lack information about the profitability of variable rate technology (VRT) for agricultural sprayers. An economic framework was developed to evaluate the returns required to pay for VRT investments. Payback variables included input savings, yield gains, and reduced application costs. We illustrate the framework with two example investment scenarios.
Amara è la giustizia di Radamante. Carlo Michelstaedter e l’antica discordia tra poesia e filosofia
Creators: name: Micheletti, David

description: What makes Carlo Michelstaedter’s life and work (1887 - 1910) worthy of a reflection on Italian aesthetics is his erratic attitude when taking a stance in the ancient discord between Philosophy and Poetry. This, since Plato’s times (Republic 607b-608b), as an original item, expects and transcends each historical chapter of the literary critique and each kind of philosophy of history. Michelstaedter justapoxes names such as Parmenides, Sophocles, Socrates, Christ and the Ecclesiastes in an anti-genealogical manner, that is against fathers and masters as well as sons and disciples. Everything that, in his short life, he could read and study in Latin, Greek, German and Italian, was bound to death against institutions and codes, against the family and the University, against the audience and every literary genre attended by the world in which he was born. Michelstaedter reads Parmenides’ Carminum reliquiae as a poetic emergency and sees in Socrates the one who becomes this poetry. The bold link between Parmenides’ ontology and Socrates’ dialectics constitutes the climax of an iconoclastic and anti-mimetic poiesis. Rhadamanthus’ justice (Gorgias 523e), results bitter to Michelstaedter. It discerns, that is, the original relationship of Socrates with death (a dreamless slumber) from that which was superimposed by Plato (the dream of a naked soul in the isles of the blissful); he distinguishes Socrates’ beautiful death from that which was enticed by Hegesias, the death-persuader, in the naive; he places Socrates next to Sophocles and the Ecclesiastes, against the mortal event of the birth. Socrates, in case, did not die because of the “cicuta” which parted him from the pain of living, nor because of the eternal idea that he’s been contemplating ever since with his immortal soul. He died, instead, after having become something divine and devilish, something that distracts him since his childhood from everything he is about to do, every time, and eventually leads him nowhere (Apology 31c-d). From this anti-contemplative perspective, Michelstaedter acknowledges in every philosophy intended to reconcile the absolute and relative, the rhetoric artifice aimed at concealing an original aporia which can only be dishonestly swayed, rather than overcome.

Cosmological Evolution of Flat-Spectrum Radio Quasars based on the {\it Swift}/BAT 105-month Catalog and Their Contribution to the Cosmic MeV Gamma-ray Background Radiation

description: We present a new X-ray luminosity function of flat-spectrum radio quasars (FSRQs) utilizing the latest {\it Swift}/BAT 105-month X-ray source catalog. Contrary to previous studies of FSRQs in the X-ray band, using the luminosity-dependent density evolution model, we find that FSRQs show evolutionary peaks at $z\sim1-2$ depending on luminosities. Our result is rather consistent with the evolution of FSRQs seen in the radio and GeV bands, although the number density is a factor of 5--10 smaller. We further explore the contribution of FSRQs to the cosmic MeV gamma-ray background radiation. We find that FSRQs can explain only $\sim3$\% of the observed MeV gamma-ray background fluxes around 1 MeV, indicating other populations are required. Future MeV gamma-ray observations will be keys for understanding the origin of the MeV gamma-ray background radiation.

description: A general formalism for the calculation of the differential cross section and polarization observables, for the process of deuteron electrodisintegration, is developed in the framework of relativistic impulse approximation. A detailed analysis of the general structure of the differential cross section and polarization observables for the $e^-+d\to e^-+n+p$ reaction is derived, using the formalism of the structure functions. The obtained expressions have a general nature and they hold in the one--photon--exchange mechanism, assuming P--invariance of the hadron electromagnetic interaction. The model of relativistic impulse approximation is introduced and the final state interaction is taken into account by means of the unitarization of the helicity amplitudes. A detailed description of the unitarization procedure is also presented. Using different parametrizations of the deuteron wave functions, the following polarization observables are calculated in the kinematical region of quasi--elastic deuteron electrodisintegration: the asymmetry for the scattering of longitudinally polarized electrons on a polarized deuteron target, the proton and neutron polarizations (for longitudinally polarized electron beam or vector--polarized deuteron target). The sensitivity to the neutron electric form factor is also thorougly investigated. The predictions of the model are compared with the results of recent polarization measurements and a good agreement with the existing experimental data has been obtained.

Sull’intelligibilità del sensibile. Nota al contributo di Adelchi Baratono nell’estetica italiana del primo Novecento

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico

description: The contribution examines the notion of occasionalismo sensista, or also known by the expression of formalismo sensista, that the Italian philosopher Adelchi Baratono was proposing in the ’30s and ’40s of the twentieth century. Best known for his dense volume, Il mondo sensibile. Introduzione all’estetica (1934), Baratono is among the first thinkers of his time in Italy to start a confrontation with Kantian criticism in aesthetic context, looking groundwork for an alternative route to the one proposed by the Italian Neo-idealism. In fact, against the absolutization of the subject, which Baratono ascribes, in particular, to the thought of Giovanni Gentile, he affirms the profound otherness of subject and object in front of which philosophy is bound to be wrecked. In this perspective, the “sensible world” for Baratono is in itself, regardless of the knowing subject, because everything is resolved in the “world within and around us”. In this perspective, Baratono affirms that the feeling is all this, that is something without which are neither perception nor the concept and even the idea. The feeling, therefore, far from being considered the first stage of knowledge, is the real existence.

Situated observation and participation in multiple-agent systems
Creators: name: Montgomery, Jefferson D.
Publisher: name: University of British Columbia
Year: 2009

description: A situated agent is not only embedded within its environmental system, but forms an integral and active component of the system as a whole. Accordingly, there are numerous requirements that a situated agent must meet including synchronization with and responsiveness to the system dynamics as well as appropriate and proactive operation — a non-trivial challenge made difficult primarily due to varying environment states and dynamics, difficult tasks with ambitious requirements, and noisy or ambiguous sensory and background information. This thesis addresses these issues by introducing an agent architecture with an interruptible and modular design capable of producing quality-varying solutions based on constraints. The architecture adaptively schedules deliberation processes which enables the agent to evolve its action with the natural frequency of the environment's dynamics. Resource-bounded deliberation is attained by attributing intentions to the agent, posed in the form of constraints, that influence its action. The thesis demonstrates how these constraints can be designed to achieve complex behaviours. Further, it shows that abstraction of behaviours based on a theory of intentionality provides a comfortable and tractable model not only for behaviour generation but also for behaviour recognition. The theory of intentionality is transcribed into a dynamic, probabilistic model that describes multiple, intentional agents and their environment. It is shown how the properties of intentionality, so transcribed, produce a computationally attractive model that allows real-time approximate inference. Ultimately, a novel agent is introduced for the particular multiple-agent domain of robot soccer. The agent is implemented and tested to study the reactivity of the architecture, accuracy of the environmental modelling, and effectiveness of its deliberation.
