    • Adaptive distance sampling 

      Pollard, John (University of St Andrews, 2002) - Thesis
      We investigate mechanisms to improve efficiency for line and point transect surveys of clustered populations by combining the distance methods with adaptive sampling. In adaptive sampling, survey effort is increased when ...
    • Alfvén waves in low-mass star-forming regions 

      Martin, Clare E. (University of St Andrews, 1999) - Thesis
      Low-mass star-forming regions have a lifetime which is greater than their dynamical time and must therefore be, in an average sense, in mechanical equilibrium. The work presented here proposes that an equilibrium exists ...
    • An algebraic formulation of asmptotically separable quantum mechanics 

      McLean, R. G. Derek (University of St Andrews, 1984) - Thesis
      This thesis explores the possibility of an algebraic formulation of non-relativistic quantum theory in which certain paradoxes associated with non-locality may be resolved. It is shown that the localisation of a free quantum ...
    • Algorithms for subgroup presentations: computer implementation and applications 

      Heggie, Patricia, M. (University of St Andrews, 1991) - Thesis
      One of the main algorithms of computational group theory is the Todd-Coxeter coset enumeration algorithm, which provides a systematic method for finding the index of a subgroup of a finitely presented group. This has been ...
    • Alternating direction implicit methods for partial differential equations 

      Fairweather, Graeme (University of St Andrews, 1966) - Thesis
    • Alternating direction methods for hyperbolic systems 

      Gourlay, A. R. (University of St Andrews, 1966) - Thesis
    • Application of the Todd-Coxeter coset enumeration algorithm 

      Campbell, C. M. (Colin Matthew) (University of St Andrews, 1975) - Thesis
      This thesis is concerned with a topic in combinatorial group theory and, in particular, with a study of some groups with finite presentations. After preliminary definitions and theorems we describe the Todd-Coxeter coset ...
    • Approximate methods in high speed flow 

      Burnside, Robert R. (University of St Andrews, 1962) - Thesis
      In many problems arising in the theory of compressible flow, the equations characterising the solution of the system are so intractable that recourse must be made to some approximate method which allows the essential ...
    • The Arabic translation of Theodosius's Sphaerica 

      Martin, Thomas J. (University of St Andrews, 1975) - Thesis
      The thesis "The Arabic Translation of Theodosius's Sphaerica" is an edition of the Istanbul manuscript Topkapi Seray Ahmet III 3464.2. Included is a comparative apparatus of the Greek and Arabic texts showing possible ...
    • Aspects of current sheet theory 

      Tur, T. J. (University of St Andrews, 1977) - Thesis
      Current sheets are widely believed to play an important role in astrophysics when regions of magnetic flux are in motion. Several models based on the formation of current sheets have been proposed to explain such phenomena ...
    • Aspects of magnetic field theory in solar and laboratory plasmas 

      Lothian, Robert M. (University of St Andrews, 1990) - Thesis
      Using the Magnetohydrodynamic model, two problems in the behaviour of magnetic field structures are investigated. Firstly, the stability of tokamak equilibria to coupled tearing modes is calculated. Secondly, the equilibrium ...
    • Aspects of MHD wave propagation in solar atmospheric studies 

      Mundie, Cheryl Ann (University of St Andrews, 1998) - Thesis
      The theme of this thesis is ideal linear MHD wave propagation in structured media, using models relevant to structures in the solar atmosphere. We derive dispersion relations governing the ideal linear MHD modes for ...
    • Aspects of natural convention and of non-linear hydridynamic stability 

      Usher, J. R. (University of St Andrews, 1974) - Thesis
      In Part I of this thesis, steady and time-dependent, natural-convection similarity flows with mass transfer are discussed. Similarity flows for natural convection on families of two-dimensional bodies with closed lower ...
    • Aspects of solar coronal stability theory 

      De Bruyne, Peter J. J. (University of St Andrews, 1991) - Thesis
      Solar coronal stability theory is a powerful tool for understanding the complex behaviour of the Sun's atmosphere. It enables one to discover the driving forces behind some intriguing phenomena and to gauge the soundness ...
    • Aspects of the MHD stability of coronal and laboratory plasmas 

      Clifford, Leo J. (University of St Andrews, 1993) - Thesis
      The magnetohydrodynamic (MHD) model is a simple mathematical model that treats a plasma as a perfectly conducting fluid acted upon by magnetic and pressure-driven forces. Many instabilities in plasmas can be predicted using ...
    • The asymptotic distribution and robustness of the likelihood ratio and score test statistics 

      Emberson, E. A. (University of St Andrews, 1995) - Thesis
      Cordeiro & Ferrari (1991) use the asymptotic expansion of Harris (1985) for the moment generating function of the score statistic to produce a generalization of Bartlett adjustment for application to the score statistic. ...
    • Automated theorem proving for mathematics : real analysis in PVS 

      Gottliebsen, Hanne (University of St Andrews, 2002) - Thesis
      Computer Algebra Systems (CASs), such as Maple and Mathematica, are now widely used in both industry and education. In many areas of mathematics they perform well. However, many well-established methods in mathematics, ...
    • Automatic S-acts and inverse semigroup presentations 

      Dombi, Erzsebet Rita (University of St Andrews, 2005) - Thesis
      To provide a general framework for the theory of automatic groups and semigroups, we introduce the notion of an automatic semigroup act. This notion gives rise to a variety of definitions for automaticity depending on the ...
    • Automatic semigroups : constructions and subsemigroups 

      Descalco, L. (University of St Andrews, 2002) - Thesis
      In this thesis we start by considering conditions under which some standard semigroup constructions preserve automaticity. We first consider Rees matrix semigroups over a semigroup, which we call the base, and work on the ...
    • Basic magnetic field configurations for solar filament channels and filaments 

      Mackay, Duncan Hendry (University of St Andrews, 1997) - Thesis
      The three-dimensional magnetic structure of solar filament channels and filaments is considered. A simple analytical potential model of a filament channel is setup with line sources representing the overlying arcades and ...
