    We study those (2,m,n)(2, m, n)-groups which are almost simple and for which the absolute value of the Euler characteristic is a product of two prime powers. All such groups which are not isomorphic to PSL2(q)PSL_2 (q) or PGL2(q)PGL_2(q) are completely classified

    World. An anthropological examination (part 2)

    Get PDF
    This paper is the second of a two-part essay that aims to examine anthropologically the category “world.” The first part argued in favor of a single-world approach and for the unavoidable centrality of personhood in the human condition. In this second part of the essay, I address the metaphysical implications of the category “world” and relate them to the process of “worlding,” thus defending the continued heuristic value of the old anthropological category of worldview. I suggest that a consideration of the Ontological Proof of God’s existence, developed by St. Anselm of Canterbury in the late eleventh century, helps us develop a comparative theory of personhood by showing how the experience of transcendence is inherent in personal ontogenesis

    Collaborative Development of Open Educational Resources for Open and Distance Learning

    Open and distance learning (ODL) is mostly characterised by the up front development of self study educational resources that have to be paid for over time through use with larger student cohorts (typically in the hundreds per annum) than for conventional face to face classes. This different level of up front investment in educational resources, and increasing pressures to utilise more expensive formats such as rich media, means that collaborative development is necessary to firstly make use of diverse professional skills and secondly to defray these costs across institutions. The Open University (OU) has over 40 years of experience of using multi professional course teams to develop courses; of working with a wide range of other institutions to develop educational resources; and of licensing use of its educational resources to other HEIs. Many of these arrangements require formal contracts to work properly and clearly identify IPR and partner responsibilities. With the emergence of open educational resources (OER) through the use of open licences, the OU and other institutions has now been able to experiment with new ways of collaborating on the development of educational resources that are not so dependent on tight legal contracts because each partner is effectively granting rights to the others to use the educational resources they supply through the open licensing (Lane, 2011; Van Dorp and Lane, 2011). This set of case studies examines the many different collaborative models used for developing and using educational resources and explain how open licensing is making it easier to share the effort involved in developing educational resources between institutions as well as how it may enable new institutions to be able to start up open and distance learning programmes more easily and at less initial cost. Thus it looks at three initiatives involving people from the OU (namely TESSA, LECH-e, openED2.0) and contrasts these with the Peer-2-Peer University and the OER University as exemplars of how OER may change some of the fundamental features of open and distance learning in a Web 2.0 world. It concludes that while there may be multiple reasons and models for collaborating on the development of educational resources the very openness provided by the open licensing aligns both with general academic values and practice but also with well established principles of open innovation in businesses

    Perfect countably infinite Steiner triple systems

    We use a free construction to prove the existence of perfect Steiner triple systems on a countably infinite point set. We use a specific countably infinite family of partial Steiner triple systems to start the construction, thus yielding 2â„”0 non-isomorphic perfect systems

    Finite scattering amplitudes in field theory

    Get PDF
    In this thesis we explore the infrared problem perturbatively in massless field theory. We review the current conventional methods and theorems that are applied in the calculation of QCD jet observables and then discuss the formulation of an alternative approach called the Asymptotic Interaction Picture (AIP). The AIP is based on a unitary transformation such that long-ranged interactions are present in the asymptotic Lagrangian and thus the states associated with this picture are no longer free Fock states but are asymptotic states containing soft and collinear interactions. Under the guidance of the AIP we are led to modifying conventional perturbation theory, cutting up amplitudes in a manner that allows for the construction of infrared finite amplitudes that are in correspondence with the asymptotic states of the AIP. We apply this formalism to several NLO corrections to QCD observables and construct dressed states who's amplitudes are finite in all regions of phase space. Using these amplitudes we compute several observables and show agreement with the conventional calculations in infrared safe regions. Higher-order calculations are then investigated in ϕ (^3)theory and the infrared pole structure is shown to behave as expected such that NNLO corrections to dressed states are obtained. Finally we present part of the NNLO correction to the dressed two-parton amplitude in QCD and show that, with several provisos, this approach may potentially be applied to the precision calculations of observables at the International Linear Collider (ILC). We therefore give a possible alternative to current subtraction methods at NNLO when no initial state radiation is present

    Searching and ranking ontologies on the Semantic Web

    Get PDF
    The number of ontologies available online is increasing constantly. Tools that are capable of searching, retrieving, and ranking ontologies are becoming crucial to facilitate ontology search and reuse. In this document, we describe OntoSearch, which is a tool for capturing and searching ontologies on the Semantic web. We also briefly describe AKTiveRank which is used to rank OWL ontologies based on certain ontology-structure analysis.

    How To MANAGE a Small Law Firm was founded by attorney RJon Robins. He quickly realized that despite having done quite well in law school, completing a prestigious 9 credit internship with the US Trustee’s Office and clerking for a Federal Bankruptcy Judge, he knew next to nothing about how to actually manage the business of a small law firm. RJon did eventually discover how to manage a small law firm and was recruited by The Florida Bar’s Law Office Management Assistance Service (LOMAS) to teach his fellow lawyers how to find, fix and avoid the sort of marketing, sales, management, staffing, and financial control problems that had plagued his law firm. As a full-time LOMAS Small Law Practice Management Advisor RJon had the unique opportunity to work with several thousand owners of solo and small law firms to diagnose the sources and help them fix the problems that plagued their law firms too. In 2008 RJon founded How To MANAGE a Small Law Firm.com which has since grown to be the largest provider of outside Managing Partner services in the Country. We are dedicated exclusively to the unique needs of the owner of a solo or small law firm. Today How To MANAGE A Small Law Firm boasts coast-to-coast Membership with ambitious and entrepreneurial lawyers hailing from all practice areas and walks of life. We even have Members in foreign Countries too

    A Modified Distortion Measurement Algorithm for Shape Coding

    Get PDF
    Efficient encoding of object boundaries has become increasingly prominent in areas such as content-based storage and retrieval, studio and television post-production facilities, mobile communications and other real-time multimedia applications. The way distortion between the actual and approximated shapes is measured however, has a major impact upon the quality of the shape coding algorithms. In existing shape coding methods, the distortion measure do not generate an actual distortion value, so this paper proposes a new distortion measure, called a modified distortion measure for shape coding (DMSC) which incorporates an actual perceptual distance. The performance of the Operational Rate Distortion optimal algorithm [1] incorporating DMSC has been empirically evaluated upon a number of different natural and synthetic arbitrary shapes. Both qualitative and quantitative results confirm the superior results in comparison with the ORD lgorithm for all test shapes, without any increase in computational complexity

    Development of a viable concrete printing process

    Get PDF
    A novel Concrete Printing process has been developed, inspired and informed by advances in 3D printing, which has the potential to produce highly customised building components. Whilst still in their infancy, these technologies could create a new era of architecture that is better adapted to the environment and integrated with engineering function. This paper describes the development of a viable concrete printing process with a practical example in designing and manufacturing a concrete component (called Wonder Bench) that includes service voids and reinforcement. The challenges met and those still to be overcome particularly in the evaluation of the manufacturing tolerances of prints are also discussed
