The Yorkshire Dales National Park contains some of the UK’s most extensive and well-preserved prehistoric landscapes. Of particular interest are a number of coaxial field systems, which cover hundreds of hectares and exhibit significant time-depth, yet remain little studied and poorly understood in relation to comparable resources elsewhere in Britain and north western Europe. This research aims to address this situation, bringing together existing disparate source materials for the first time, alongside supplementary field observation, to develop a detailed record of the coaxial landscapes. Using a Geographic Information System to manage, interpret and interrogate the combined datasets, analysis focuses on form and character, and explores prehistoric use of the iconic landscape. The study seeks to enhance our knowledge and understanding of the landscapes’ place in space and time, setting them against the backdrop of systems elsewhere, and attempts to place them within the context of later prehistoric society. The research, conducted in association with the Yorkshire Dales National Park Authority, also informs the management and public understanding of the archaeological resource of the Dales via the Historic Environment Record.

The large-scale field-systems, ubiquitous across upland and marginal parts of the Yorkshire Dales, are insecurely dated and poorly understood. Apart from some sporadic academic interest, the archaeology of this region has yet to receive the level of scholarly attention it deserves. The research presented here involved an intensive investigation of an area near Grassington, Upper Wharfedale, UK. Detailed field analysis revealed a section of one of these field-systems to be only a single element in a complex, multi-layered prehistoric landscape, which it is proposed may have roots as far back as the early Neolithic. Contextualisation of the survey area against palynological data, radiocarbon dates and comparative material moves the date of inception of the field-systems back to the middle Bronze Age, some 1000 years earlier than is currently assumed. The combination of empirical data and theoretical ideas has allowed a relative chronology to be determined in the survey area, together with the creation of a testable hypothesis surrounding the development of Upper Wharfedale and the wider Yorkshire Dales through prehistory. A sense of place and the veneration of natural places are key themes within this landscape and it was possible through these to draw out elements of prehistoric society and to show the evolution of ideas such as land tenure and monument significance. This dual empirical-theoretical approach is novel in upland landscape archaeology in the UK and is shown here to have significant merit.

The purpose of this thesis is to elucidate the importance of the enclosure movement for the agricultural development in the area of Mälardalen, Sweden. This is done through a case study of Torstuna härad between the years 1750-1914 by sampling five points in time. By studying the long term development of land reclamation and its correlation with meadow acreage, crop rotation and animal stock the thesis argues that the the radical enclosures in the 1850’s was a course of action to regain opportunities for agricultural expansion. The most intense period of land reclamation was after the implementation of radical enclosure which brought with it a change from communal land use to private ownership. Private property rights meant a new set of advantages for the individual farmer to plan and invest and balance the arable and the meadow.

Two particular systems are the focus of the study: the Mindin-Timoshenko system, describing the vibrational motion of a plate or a beam, and the phase eld system describing the temperature and phase of a medium having two distinct physical states. The rst chapter is devoted to the study of the 1-D Mindlin-Timoshenko system with discontinuous coe cient. A Carleman inequality is obtained under the assumption of monotonicity on the beam speed. Subsequently, two applications are provided: the controllability of the control system acting on the boundary and Lipschitzian stability of the inverse problem of recovering a potential from a single measurement of the solution. In the second chapter we consider a contact problem characterized by the behavior of a two-dimensional plate whose board makes contact with a rigid obstacle. The formulation of this problem is presented by the 2-D Mindlin-Timoshenko system with boundary conditions and suitable damping terms. Concerning such system, is proved via penalty techniques, the existence of solution and that the system energy has exponential decay when the time approaches in nity. In the third chapter, the study is aimed at a nonlinear phase- eld system de ned in a real open interval. Here we present some controllability results when a single control acts, by means of Dirichlet conditions, on the temperature equation of the system on one of the endpoints of the interval. To prove the results is used the method of moments, plus a spectral study of operators associated to the system and xed point theory to deal with the nonlinearity. / Nesta tese estudamos resultados de controlabilidade, comportamento assintótico e problema inverso relacionados a alguns problemas da teoria de equações diferenciais parciais. Dois sistemas particulares são foco do estudo: o sistema de Mindin-Timoshenko, que descreve o movimento vibratório de uma placa ou viga, e o sistema de campo de fases que descreve a temperatura e a fase de um meio onde ocorrem dois estados físicos distintos. O primeiro capítulo é dedicado ao estudo do sistema de Mindlin-Timoshenko 1-D com coe ciente descontínuos. Uma desigualdade de Carleman é obtida sob a hipótese de monotonicidade sobre velocidade da viga. Posteriormente, são fornecidas duas aplicações: a controlabilidade do sistema com controles agindo na fronteira e a estabilidade Lipschitziana do problema inverso de recuperar um potencial através de uma única informação obtida sobre a solução. No segundo capítulo consideramos um problema de contato caracterizado pelo comportamento de uma placa bidimensional cujo bordo faz contato com um obstáculo rígido. A formulação deste problema é apresentada pelo sistema de Mindlin-Timoshenko 2-D com condi ções de fronteira e termos de amortecimento (damping) adequados. Sobre tal sistema, é provada, através de técnicas de penalização, a existência de solução e, posteriormente, que sua energia possui decaimento exponencial quando o tempo tende ao in nito. No terceiro capítulo o estudo é voltado a um sistema de campo de fases não-linear de nido em um intervalo aberto real. Neste espaço apresentamos alguns resultados de controlabilidade quando um único controle age, sob condições de Dirichlet, na equação da temperatura em um dos bordos do intervalo. Para provar os resultados é utilizado o método dos momentos, além de uma estudo espectral de operadores associados ao sistema e teoria de ponto xo para lidar com a não-linearidade.
