Commercial prosthetic feet weigh about 25% of their equivalent physiological counterparts. The human body has a tendency to overcome the walking asymmetry resulting from the mass imbalance by exerting more energy. A two link passive walking kinematic model, with realistic masses for prosthetic, physiological legs and upper body, has been proposed to study the gait pattern with unbalanced leg masses. The 'heel to toe' rolling contact has significant influence on the dynamics of biped models. This contact is modelled using the roll-over shape defined in the local co-ordinate system aligned with the stance leg. The effect of rollover shape curvature and arc length has been studied on various gait descriptors such as average velocity, step period, inter leg angle (and hence step length), mechanical energy. The bifurcation diagrams have been plotted for point feet and different gain values. The insight gained by studying the bifurcation diagrams for different gain and length values is not only useful in understanding the stability of the biped walking process but also in the design of prosthetic feet. It is proposed that the stiffness and energy release mechanisms of prosthetic feet be designed to satisfy amputee's natural gait characteristics that are defined by an effective roll-over shape and corresponding ground reaction force combinations. Each point on the roll-over shape is mapped with a ground reaction force corresponding to its time step. The resulting discrete set of ground reaction force components are applied to the prosthetic foot sole and its stiffness profile is optimised to produce a desired deflection as given by the corresponding point on the roll-over shape. It is shown that the proposed methodology is able to provide valuable insights in the guidelines for selection of materials for a multi-material prosthetic foot.

This thesis examines the double-voiced representations of disability and illness in several works by Montgomery, the <i>Emily</i> trilogy (1923, 1925, 1927), the novel <i>The Blue Castle </i>(1926), the novella <i>Kilmeny of the Orchard </i>(1910), and two short stories, <i>The Tryst of the White Lady</i> (1922) and <i>Some Fools and a Saint</i> (published in 1931 but written in 1924). Although most of Montgomerys fiction in some way discusses illness and disability, often through secondary characters with disabilities, these works in particular feature disability as a central issue and use their heroes and heroines disabilities to impel the plots. While with one voice these works comply with conventional uses of disability in the love story genre, with another they criticize those very conventions. Using disability theory to analyze the fictions double voice, my thesis reveals that the ambiguity created by the internal conflict in the texts evades reasserting the binary relationship which privileges ability and devalues disability. <p> This thesis uses disability theory to examine the double-voiced representation of disability in the fiction of L.M. Montgomery. Bakhtin describes the double voice as an utterance which has two speakers at the same time and expresses simultaneously two different intentions: the direct intention of the character who is speaking and the refracted intention of the author (324). In this thesis, however, I perceive the double voice not as the difference between the voices of the speaking character or narrator and of the authors intention. Instead, I will approach the double voice as simultaneous expressions of conflicting representations, whether or not the author intends them. These voices within the double voice internally dialogue with each other to reflect changing social attitudes toward disability. By applying disability theories, such as those by critics David Mitchell and Sharon Snyder, Susan Sontag, Martha Stoddard Holmes, and Rosemarie Garland Thomson, that assess how texts invoke disability as a literary technique, this thesis shows that the narrative structure of Montgomerys fiction promotes the use of disability as a literary and social construct, while its subtext challenges the investment of metaphoric meaning in disability.
