description: This dataset was used to analyze the impact of snow cover accumulation on residential PV installations and its effect on energy production shortages, expressed as anomalies in measured daily solar irradiance. The study was conducted for 4 locations in 3 Polish cities, where meteorological measurement stations are located.

The .xlsx files contain daily data:

electricity production from photovoltaic installations in Poland obtained from PVmonitor.pl database (raw minute data was processed and converted to daily production sum), kWh/d,

solar irradiance, Wh/(m2×d),

snow cover, cm,

ambient temperature at 2 meters, ℃.

Solar irradiance, snow cover, and temperature data were obtained from the Polish Institute of Meteorology and Water Management (IMGW) database. Due to data scarcity, one month (March) was excluded for the Lodz_100789 location.

Figure 4
 Females examined: 15. 11 with complete sphragides; 3 bearing incomplete or amorphous sphragides.
 Description: Coloration—golden-brown. Shape—rounded anteriorly with two symmetrical lateral cavities, an elevated projection medially, and the sphragis curves upward and over the sterigma posteriorly, overhanging the sterigma. The tip of the sphragis is pointed and nearly touches the papillae anales. Structure—mostly solid. Scales—present, ordered, hair-like. Attached to leading edge of the overhanging posterior half of sphragis.
 Comments: We observed one female with a spermatophore attached to the sphragis outside of the female body (Fig. 4D). It is likely that there was already a sphragis in place on the female’s sterigma, and that the second male was unsuccessful in depositing his spermatophore inside the female’s reproductive tract, but still produced a complete sphragis on top of the first one.

Communicative acts of young children in structured elicitation contexts
Creators: name: MacLachlan, Shannon Lee
Publisher: name: University of British Columbia
Year: 2011

description: The relationship between communication skills over time, and the knowledge that early intervention improves a child's long-term outcome, reinforces the need for valid and reliable measures of young children's communication skills. The current study evaluated communication abilities of 34 children (1;5 - 2;0), some with and some without family history of language delay. The major purpose was to document rate, discourse type (initiation or response), mode, and speech act type in these children's communication and determine age or gender differences. A secondary objective was to determine whether standardized language test scores correlated with communicative act data. Predictions were that directives and assertives would be the most frequent speech acts and standardized language scores would correlate with speech act data. Children participated in a structured play session as part of a larger longitudinal study. An experimenter presented a series of toys and attempted to elicit communication from the child with minimal prompting. Data were audio- and video-taped, then orthographically transcribed and coded according to whether the utterance was communicative or not, where the child's focus of attention lay, whether an utterance was an initiation or response, and in what the mode and what the function of communication were. Utterance function was defined according to speech act theory, defined by Searle and Vanderveken (1985) and modified by Klincans (1991; Johnson & Klincans, 1999). Children communicated at an average rate of 8.6 utterances/ minute. Initiations increased with child age, although there was much variability among children and across activities; responses were not related to child age. Mode differed by activity, with verbalizations related to increasing child age. The most frequent speech act types were, in order, directive, assertive, and expressive, with utterances coded 'ambiguous' between directives and assertives in frequency. Significant correlations were found between speech act data and standard testing scores for: initiations and PLS-AC, verbalizations and PLS-AC, and assertives and PLS-AC, PLS-EC, and CDl scores. These results, particularly the relationship between assertives and language scores, suggest that speech act analysis can contribute to the valid and reliable evaluation of communication skills in structured contexts of children under age 2;0 and also predict some language abilities of children at this difficult-to-test age.
title: Knowledge aquisition for expert systems: inducing modular rules from examples
Creators: name: Cendrowska, Jadzia
Publisher: name: The Open University
Year: 1990

description: Knowledge acquisition for expert systems is notoriously difficult, often demanding an enormous effort on the part of the domain expert, who is essentially expected to spell out everything he knows about the domain. The task is non-trivial and can be time-consuming and tedious. Machine learning research, particularly into automatic rule induction from examples, may provide a way of easing this burden. Arguably, the most popular and successful rule induction algorithm in general use today is Quinlan's ID3. ID3 induces rules in the form of decision trees. However, the research reported in this thesis identifies some major limitations of a decision tree representation. Decision trees can be incomprehensible, but more importantly, there are rules which cannot be represented by trees. Ideally, induced rules should be modular and should capture the essence of causality, avoiding irrelevance and redundancy. The information theoretic approach employed in ID3 is examined in detail and some of its weaknesses identified. A new algorithm is developed which, by avoiding these weaknesses, induces rules which are modular rather than decision trees. This algorithm forms the basis of a new rule induction program, PRISM. Given an ideal training set, PRISM induces a complete and correct set of maximally general rules. The program and its results are described using training sets from two domains, contact lens fitting and a chess endgame. Induction from incomplete training sets is discussed and the performance of PRISM is compared with that of ID3 with particular reference to predictive power. A series of experiments is described, in which PRISM and ID3 were applied to training sets of different sizes and predictive power calculated. The results show that PRISM generally performs better than ID3 in these two domains, inducing fewer, more general rules, which classify a similar number of instances correctly and significantly fewer incorrectly.

description: In the present paper, we use a coarse-graining approach to investigate the nonlinear redistribution of free energy in both position and scale space for weakly collisional magnetised plasma turbulence. For this purpose, we use high-resolution numerical simulations of gyrokinetic (GK) turbulence that span the proton-electron range of scales, in a straight magnetic guide field geometry. Accounting for the averaged effect of the particles' fast gyro-motion on the slow plasma fluctuations, the GK approximation captures the dominant energy redistribution mechanisms in strongly magnetised plasma turbulence. Here, the GK system is coarse-grained with respect to a cut-off scale, separating in real space the contributions to the nonlinear interactions from the coarse-grid-scales and the sub-grid-scales (SGS). We concentrate on the analysis of nonlinear SGS effects. Not only that this allows us to investigate the flux of free energy across the scales, but also to now analyse its spatial density. We find that the net value of scale flux is an order of magnitude smaller than both the positive and negative flux density contributions. The dependence of the results on the filter type is also analysed. Moreover, we investigate the advection of energy in position space. This rather novel approach for GK turbulence can help in the development of SGS models that account for advective unstable structures for space and fusion plasmas, and with the analysis of the turbulent transport saturation.

title: East India patronage and the political management of Scotland 1720-1774
Creators: name: McGilvary, George Kirk
Publisher: name: The Open University
Year: 1990

description: This thesis sets out to examine and explain the use of India patronage in the government of Scotland from 1720 to 1774. The 1707 Act of Union created a complex and uncertain Scottish political world. Widespread resentment at the 1707 'betrayal' was kept simmering by pro-Jacobite sentiments and frustrations due to economic stagnation. To the Whig ministries in London the 1715 rebellion on top of all the other danger signals was alarming. The turmoil in Scotland seemed to threaten the stability and security of the fragile British state. Walpole believed the danger sufficient to warrant the strongest political management system possible there, using all the patronage that could be brought to bear. Through John Drummond, a Scottish East India Company Director, he was able to procure patronage from the Company and its Shipping interest. In Scotland these India posts were devoted to obtaining electoral support for Walpole's Argathelian backers. John Drummond and Lord Milton, as agents of the Duke of Argyll and his brother Islay, were instrumental in this. Walpole's successors at Westminster and the Argathelians in Scotland conspired to further the use of available India patronage. The flood of India favours continued until 1765 and beyond, pausing only with the implementation in 1774 of North's Regulating Act. The thesis breaks new ground in showing the existence and importance of this India patronage so early in the eighteenth century. Also, by examining the role of the Scots engrossed in the East India Company and its politics in the 1760s and early 1770s their importance as a group is uncovered. They were caught up in the struggle for power and for control of patronage within the Company, as well as that between Parliament and the Company for control of Indian territorial acquisitions.

description: The seesaw model of heavy and light Majorana neutrinos and its low-energy effective theory are studied, when the number of heavy neutrinos is equal to or less than the number of light lepton generations. We establish a general relationship between the high-energy parameters and the low-energy observables involving only the light fields. It is shown how low-energy measurements of the properties of light neutrinos suffice a priori to determine all couplings of the unobserved heavy neutrinos. CP violation is present in low-energy processes if seesaw-model leptogenesis creates the matter-antimatter asymmetry of the universe.

The efficiency of the magnetic acceleration in relativistic jets

Subjects: subject: Astrophysics (astro-ph)

description: Using steady, axisymmetric, ideal magnetohydrodynamics (MHD) we analyze relativistic outflows by means of examining the momentum equation along the flow and in the transfield direction. We argue that the asymptotic Lorentz factor is ~ mu-sigma_M, and the asymptotic value of the Poynting-to-matter energy flux ratio - the so-called sigma function - is given by sigma/(1+sigma) \~ sigma_M / mu, where sigma_M is the Michel's magnetization parameter and mu c^2 the total energy-to-mass flux ratio. We discuss how these values depend on the conditions near the origin of the flow. By employing self-similar solutions we verify the above result, and show that a Poynting-dominated flow near the source reaches equipartition between Poynting and matter energy fluxes, or even becomes matter-dominated, depending on the value of sigma_M / mu.

title: Feminist issues in education: developing a theory of class and gender relations
Creators: name: Arnot, Madeleine M.
Publisher: name: The Open University
Year: 1989

description: The twelve publications submitted for this thesis constitute a group of essays completed between 1979 and 1989 on related feminist issues in education. Each publication contributes to the overall project of developing a theory of class and gender relations in education. Three stages in the construction of this theory are identified. These are: (a) a critical evaluation of theories concerning the social and cultural reproduction of class relations in terms of their applicability to the study of gender relations. (b) the construction of a feminist theory of gender that accounts for, among other things, the historical and class specific nature of gender relations in education. (c) an analysis of contemporary policy-making at central, local and institutional levels in relation to the promotion of equal opportunities for both sexes. It is suggested that explanations of the relationship between education, the economy, the family and the state based upon male class relations cannot adequately account for the patterns of female education. A range of new concepts more appropriate for the study of gender relations is developed. These include a theory of male hegemony and the concept of gender code involving processes of recontextualisation and different modes of transmission of gender relations through schooling. These concepts are applied to an analysis of the structure and content of the secondary school curriculum, family and school cultures, coeducation and boys' education. The approach developed here is contrasted with other feminist perspectives on gender and education and consideration is given to the ways in which these perspectives have influenced educational policy and practice. The approaches to sex equality of central government are compared with those underlying teacher initiatives in this area. Finally a strategy is offered for the promotion of sex equality through school-based in-service courses focused on the personal and professional development of teachers.

description: Indonesia's potato industry is undergoing a rapid transformation, presenting producers with new and more profitable opportunities to participate in modem food retail channels. This study explores the ways producers can enter modem chains and how various channels suit the individual characteristics of different producers. We surveyed three groups of farmers in the largest potato-producing area in Indonesia. This article provides a conceptual model and an empirical analysis of the buyer­ seller relationship in the potato industry in Indonesia. Using multivariate analysis of variance (MANOVA) and linear regression methods, the study reveals that flexibility and dependence are determinate factors of trust.
title: Random close packing (RCP) of equal spheres: structure and implications for use as a model porous medium
Creators: name: Mellor, David W.
Publisher: name: The Open University
Year: 1989

description: The structure of the Finney Random Close Packing (RCP) of equal spheres has been analysed, together with the influence which such structure exerts over the capillary pressure characteristics of geometrically similar sphere packings. The analysis is centred on the simplicial, or Delaunay cell, which is an irregular tetrahedron with apices defined by four immediate neighbour sphere-centres. In terms of using RCP as a model porous medium, an individual simplicial cell is equivalent to an individual pore. A number of measured pore-size distribution parameters are presented for the Finney packing, from which it is shown from first principles that drainage-imbibition hysteresis is not an intrinsic property of the individual pore. The nature and degree of randomness which characterises the Finney packing is evaluated on two levels. First, by classifying edgelengths as either short or long, seven mutually exclusive cell classes are defined. Using the binomial theorem it is shown that cells (pores) are not random on the level of the individual cell. There are less of the extreme cells (with 6 long edges, or with 6 short edges) and more of the bland cells (with 3 short and 3 long edges) in the Finney packing than predicted on the basis of simple random expectations. Second, the distribution of cell classes within the packing is shown to be essentially homogeneously random. Evidence for extremely slight cell class clustering is found. The drainage and imbibition processes within the packing are simulated using pore-level algorithms. The algorithms utilise both the Haines' insphere approximation and the MS-P approximation for critical drainage meniscus curvature, and the cell cavity insphere radius approximation for critical imbibition meniscus curvature. Good agreement with experimental data is obtained, and the results confirm that drainage-imbibition hysteresis is a direct consequence of the connectivity between cells (pores), and is not an intrinsic property of the individual pore. Finally, the drainage and imbibition algorithms are adapted to emulate percolation theory models. The results prove that the classical bond problem of percolation theory does not adequately describe the drainage process for RCP, and that the classical site problem does not adequately describe the imbibition process for RCP.

description: This application note summarizes precisely where PDF creators should add XMP metadata to PDF 2.0 objects, and thus where PDF 2.0 processors should search for it. In most cases metadata is all about interoperability; it is only useful if creator and processor agree on syntax and semantics. In the context of PDF this also means that creator and processor must agree on where metadata is present in the often-complex internal PDF structure. Metadata locations are well defined for XMP metadata on the PDF document level and for some PDF objects, but not for all objects where metadata can occur (pages, page objects and resources such as fonts or ICC profiles). However, in almost all cases sufficient guidance can be derived from the PDF specification, albeit sometimes in an indirect way.

description: Mobile phone (MP) technologies have been widely adopted in developing countries. Previous research has shown MP use to enhance market access through information exchange and market price integration. However, the impact of MP use on several smallholder welfare aspects has barely been investigated. In particular, we are not aware of any studies that have analyzed the effects of MP use on gender equity and nutrition – two welfare dimensions of particular importance in the context of United Nations’ sustainable development goals (SDGs). We address the gap by using a two wave balanced panel data from smallholder farm households in Uganda to examine the impact of MP use on household incomes, gender, and nutrition. Using regression models, we find that, MP use is positively and significantly associated with improvements in household income, women empowerment, and dietary diversity. Gender disaggregated analysis shows that female MP use bears stronger associations. Female MP Use’s positively associated influences on dietary diversity are channeled through increased incomes and women empowerment. These effects are due to lower transaction costs and better access to information through MP use.

description: Computational requirements for deep neural networks (DNNs) have been on a rising trend for years. Moreover, network dataflows and topologies are becoming more sophisticated to address more challenging applications. DNN accelerators cannot adopt quickly to the constantly changing DNNs. In this paper, we describe our approach to make a static accelerator more versatile by adding an embedded FPGA (eFPGA). The eFPGA is tightly coupled to the on-chip network, which allows us to pass data through the eFPGA before and after it is processed by the DNN accelerator. Hence, the proposed solution is able to quickly address changing requirements. To show the benefits of this approach, we propose an eFPGA application that enables dynamic quantization of data. We can fit four number converters on an $1.5mm^2$ eFPGA, which can process 400M data elements per second. We will practically validate our work in the near future, with a SoC tapeout in the ongoing EPI project.
Text-based Localization of Moments in a Video Corpus

description: Prior works on text-based video moment localization focus on temporally grounding the textual query in an untrimmed video. These works assume that the relevant video is already known and attempt to localize the moment on that relevant video only. Different from such works, we relax this assumption and address the task of localizing moments in a corpus of videos for a given sentence query. This task poses a unique challenge as the system is required to perform: (i) retrieval of the relevant video where only a segment of the video corresponds with the queried sentence, and (ii) temporal localization of moment in the relevant video based on sentence query. Towards overcoming this challenge, we propose Hierarchical Moment Alignment Network (HMAN) which learns an effective joint embedding space for moments and sentences. In addition to learning subtle differences between intra-video moments, HMAN focuses on distinguishing inter-video global semantic concepts based on sentence queries. Qualitative and quantitative results on three benchmark text-based video moment retrieval datasets - Charades-STA, DiDeMo, and ActivityNet Captions - demonstrate that our method achieves promising performance on the proposed task of temporal localization of moments in a corpus of videos.

description: We present BUDDA (BUlge/Disk Decomposition Analysis), a new code devoted to perform a two-dimensional bulge/disk decomposition directly from the images of galaxies. The bulge component is fitted with a generalized Sersic profile whereas disks have an exponential profile. No other components are included. Bars and other sub-structures, like lenses, rings, inner bars and inner disks, are studied with the residual images obtained through the subtraction of bulges and disks from the original images. This means that a detailed structural analysis of galaxies may be performed with a small number of parameters, and sub-structures may be directly studied with no a priori assumptions. To illustrate its usefulness, we present the results obtained with a sample of 51 mostly early-type galaxies (but covering the whole Hubble sequence). These results show some of the applications in which the code may be used: the determination of parameters for Fundamental Plane and structural studies, quantitative morphological classification of galaxies and identification and study of hidden sub-structures. We have determined the structural parameters of the galaxies in our sample and found many examples of hidden inner disks in ellipticals, secondary bars, nuclear rings and dust lanes in lenticulars and spirals, and also wrong morphological classification cases.

description: Quantum speed limits are rigorous estimates on how fast a state of a quantum system can depart from the initial state in the course of quantum evolution. Most known quantum speed limits, including the celebrated Mandelstam-Tamm and Margolus-Levitin ones, are general bounds applicable to arbitrary initial states. However, when applied to mixed states of many-body systems, they, as a rule, dramatically overestimate the speed of quantum evolution and fail to provide meaningful bounds in the thermodynamic limit. Here we derive a quantum speed limit for a closed system initially prepared in a thermal state and evolving under a time-dependent Hamiltonian. This quantum speed limit exploits the structure of the thermal state and, in particular, explicitly depends on the temperature. In a broad class of many-body setups it proves to be drastically stronger than general quantum speed limits.

description: A simulation model was developed to model the optimization problem of finishing pig delivery weights. The model was developed following a participatory problem analysis of the decision problem, to align the model as much as possible with the needs and expectations of the stakeholders. It’s functioning was tested by simulating different management strategies (i.e. finishing different sex combinations), in which differences in animal performance provoke different optima at the level of the animal and of a pig place per unit of time. The model’s results align with the findings of past studies modelling the delivery weight decision problem.

description: We present a new method to extract anisotropic flow in heavy ion collisions from the genuine correlation among a large number of particles. Anisotropic flow is obtained from the zeroes in the complex plane of a generating function of azimuthal correlations, in close analogy with the theory of phase transitions by Lee and Yang. Flow is first estimated globally, i.e., averaged over the phase space covered by the detector, and then differentially, as a function of transverse momentum and rapidity for identified particles. The corresponding estimates are less biased by nonflow correlations than with any other method. The practical implementation of the method is rather straightforward. Furthermore, it automatically takes into account most corrections due to azimuthal anisotropies in the detector acceptance. The main limitation of the method is statistical errors, which can be significantly larger than with the ``standard'' method of flow analysis if the flow and/or the event multiplicities are too small. In practice, we expect this to be the most accurate method to analyze directed and elliptic flow in fixed-target heavy-ion collisions between 100 MeV and 10 GeV per nucleon (at the Darmstadt SIS synchrotron and the Brookhaven Alternating Gradient Synchrotron), and elliptic flow at ultrarelativistic energies (at the Brookhaven Relativistic Heavy Ion Collider, and the forthcoming Large Hadron Collider at CERN).

In addition, the time evolution of the spectra due to impurity adsorption is rather gradual, and the sample surface is stable even at ambient temperature, which is in contrast with previous reports on bulk Nd2-xCexCuO4 (NCCO) single crystals. The energy distribution curves show clear dispersions near the Fermi energy (EF) with some EF crossings. The resultant Fermi surface is hole-like and centered around (pi, pi), which essentially agrees with that predicted for NCCO by band calculations and also with the experimentally determined Fermi surface of optimally doped NCCO (x = 0.15).

description: We present a theoretical estimation for the cross-section of exclusive two $ρ$-meson production in two photon collision when one of the initial photons is highly virtual. The compatibility of our analysis with recent experimental data obtained by the L3 Collaboration at LEP is discussed. We show that these data prove the scaling behavior of the exclusive production amplitude. They are thus consistent with a partonic description of the exclusive process $γγ^*\toρ^0ρ^0$ when $Q^2\sim 2 - 20 {\rm GeV^2}$.

description: The provision of public goods by agriculture and forestry has been one of the major topics of the policy debate in recent decades. From an economic point of view, public intervention related to pubic goods is justified by the fact that, due to their nature, markets do not provide prices for public goods and, as a consequence, do not allow to reach an optimal level of provision. Research has tried to deal with this topic in different ways. One pathway tries to attach a value to public goods provision to support related decision making, either using monetary or non monetary techniques. In this study we try to address those issues through the identification of typologies of rural areas within Europe based on the relevance assigned by local stakeholders operating in the field of agriculture and forestry in different European countries to different bundles of public goods and bads. In this survey, the PGBs provided by agriculture and forestry that stakeholders scored the highest are considered to be a proxy of society demand for those PGBs. The results indicated that water-related issues are the most relevant environmental concerns in the context of agriculture and forestry. However, we highlighted different relevance of PGs across regions, consistently with most of the studies addressing this issue and with known evidence about the variety of different local conditions in the EU. We identified a large group of respondents attributing a greater relevance to the Public Goods with more prounonced social dimension (in particular ‘rural viability and vitality’) with respect to the more environmental. The same group of respondents also assigned a greater importance to a few environmental Public Bads (e.g. ‘Biodiversity losses’) suggesting that PGBs are perceived as linked to specific components of the Socio-Ecological Capital (e.g. water), which are qualified depending on (threshold-related) levels.

description: It is proven that for compact, connected and semisimple structure groups every degenerate labelled web is strongly degenerate. This conjecture by Lewandowski and Thiemann implies that diffeomorphism invariant operators in the category of piecewise smooth immersive paths preserve the decomposition of the space of integrable functions w.r.t. the degeneracy and symmetry of the underlying labelled webs. This property is necessary for lifting these operators to well-defined operators on the space of diffeomorphism invariant states.

Active optical fibres in modern particle physics experiments

Year: 2004
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: In modern particle physics experiments wavelength-shifting and scintillating fibres based on plastic polymers are used for tracking and calorimetry. In this review the role of photon trapping efficiencies, transmission functions and signal response times for common multimode active fibres is discussed. Numerical simulations involving three dimensional tracking of skew rays through curved fibres demonstrate the characteristics of trapped light. Of practical interest are the parametrisations of transmission functions and the minimum permissible radius of curvature. These are of great importance in today's experiments where high count rates and small numbers of photoelectrons are encountered. Special emphasis has been placed on the timing resolution of fibre detectors and its limitation due to variations in the path length of generated photons.

description: This paper investigates the impact of corporate research and development (R&D) on firm performance in the foodprocessing industry. We apply Data Envelopment Analysis (DEA) with two step bootstrapping using a corporate data for 307 food-processing firms from the EU, US, Canada and Japan for the period 1991–2009. The estimates suggest that R&D has a positive effect on the firms’ performance, with marginal gains decreasing in the R&D level as well as the performance differences are detected across regions and food sectors. R&D investments in food processing can deliver productivity gains, beyond the high-tech sectors generally favoured by innovation policy.
Inertial torque on a small spheroid in a stationary uniform flow

description: How anisotropic particles rotate and orient in a flow depends on the hydrodynamic torque they experience. Here we compute the torque acting on a small spheroid in a uniform flow by numerically solving the Navier-Stokes equations. Particle shape is varied from oblate (aspect ratio $λ= 1/6$) to prolate ($λ= 6$), and we consider low and moderate particle Reynolds numbers (${\rm Re} \le 50$). We demonstrate that the angular dependence of the torque, predicted theoretically for small particle Reynolds numbers remains qualitatively correct for Reynolds numbers up to ${\rm Re} \sim 10$. The amplitude of the torque, however, is smaller than the theoretical prediction, the more so as ${\rm Re}$ increases. For Re larger than $10$, the flow past oblate spheroids acquires a more complicated structure, resulting in systematic deviations from the theoretical predictions. Overall, our numerical results provide a justification of recent theories for the orientation statistics of ice-crystals settling in a turbulent flow.

title: Arguement in the humanities: A knowledge based approach
Creators: name: Stutt, Arthur
Publisher: name: The Open University

description: In this thesis I have a threefold purpose. I will attempt: (a) to present a generic design for a tool - the Argument Support Program - which can be of use in supporting the reasoning of archaeologists (and others especially, but not exclusively, in the humanities); (b) I will present a model of argumentation and debate as the theoretical orientation within which the model is developed; and, (c) I will suggest that this approach is a natural development of several strands of research within the artificial intelligence community. A tripartite model of argument is presented in terms of arguers, the argument structure produced and the argument domain or field. This model subsumes reasoning, interpretation and argument exchange or debate. It is maintained, further, that while this model is generally applicable, specific domains have particular styles of argument. The notion of argument style is discussed in terms of the types of reasoning used. The related concept of relevance in argument is discussed in terms of the specific tokens of these types which may be used in a particular argument. It is argued that archaeology is characterized, at least in part, by the use of argument by analogy and argument from theoretical principles or models. A design for a generic program - the Argument Support Program (ASP) - based on the theoretical principles is delineated. Details of the partial implementation of the model as a constrained debater in the domain of archaeology (ASP for archaeology or ASParch) are presented. Example runs which illustrate how the characterizing features of archaeology are dealt with are also presented as are examples of the various domain and system knowledge bases needed. The application of ASPs to other domains and areas such as literary criticism, legal reasoning and Darwinian theory is discussed. In the final chapter, the achievements and inadequacies of this research are summarized, possible reasons are presented for the inadequacies in the resulting system and future directions discussed.

description: We consider a nearly free falling Earth satellite where atomic wave interferometers are tied to a telescope pointing towards a faraway star. They measure the acceleration and the rotation relatively to the local inertial frame. We calculate the rotation of the telescope due to the aberrations and the deflection of the light in the gravitational field of the Earth. We show that the deflection due to the quadrupolar momentum of the gravity is not negligible if one wants to observe the Lense-Thirring effect of the Earth. We consider some perturbation to the ideal device and we discuss the orders of magnitude of the phase shifts due to the residual tidal gravitational field in the satellite and we exhibit the terms which must be taken into account to calculate and interpret the full signal. Within the framework of a geometric model, we calculate the various periodic components of the signal which must be analyzed to detect the Lense-Tirring effect. We discuss the results which support a reasonable optimism. As a conclusion we put forward the necessity of a more complete, realistic and powerful model in order to obtain a final conclusion on the theoretical feasibility of the experiment as far as the observation of the Lense-Thirring effect is involved.
