Abstract:

The following presents an investigation into questions of spatial direction and continuity. This includes the directing of people via a choreographed sequence of architectural spaces through a site and a building. It further investigates a concept of continuity at various scales. A proposal for an art gallery in downtown Washington DC becomes the vehicle of exploration. The urban scale of this proposal seeks a continuity of relevant existing conditions while also creating opportunities to experience the city as well as the gallery. A serpentine-like continuous band or ribbon becomes the physi

The disadvantage that women experience in patriarchal religious communities is well documented and it affects the self-validation of their personal spiritual experiences. The patriarchal domination of women’s spirituality in conservative contexts has disempowered women’s faith-experience through limiting their ways of knowing God to those that involve a masculinised paradigm. Such limitations stifle the validation of women’s self-actuated faith.

These new radar systems feature reduced noise floors, electronic beam steering, and ultra-wide bandwidths, all of which facilitate threat discrimination. However, in order to identify missile attributes such as RF reflectivity, distance, and velocity, many existing processing algorithms rely upon narrow bandwidth assumptions that break down with increased signal bandwidth.

The hippocampal formation has been implicated in spatial formation for many decades. The hippocampus proper has received the most attention but other regions of the hippocampal formation contribute largely to spatial cognition. This thesis concentrated on one such region, the postsubiculum. The postsubiculum is considered important because it contains head direction cells and because it thought to be a major input to the hippocampus, via the entorhinal cortex. This thesis aims to test the functional role of the rat postsubiculum under two types of situation: one where the rat must rely on idio

In particular, I use conclusions of relativity theory and the acquisition of mass via the Higgs field as indications of the inadequacy of i

Abstract:

Given a Cantor-type subset Ω of a smooth curve in ℝ(d+1), we construct random examples of Euclidean sets that contain unit line segments with directions from Ω and enjoy analytical features similar to those of traditional Kakeya sets of infinitesimal Lebesgue measure. We also develop a notion of finite order lacunarity for direction sets in ℝ(d+1), and use it to extend our construction to direction sets Ω that are sublacunary according to this definition. This generalizes to higher dimensions a pair of planar results due to Bateman and Katz [4], [3]. In particular, the existence of such sets

Cancer is the number two killer after cardiovascular diseases according to the World Health Organisation.

It is the goal of 3D conformal radiotherapy and intensity modulated radiotherapy (IMRT) to maximise the radiation dose to the tumour site while minimising the dose to the surrounding normal tissues. Thus the radiation beam is shaped to conform to the tumour outline by the multileaf collimator (MLC).

Abstract:

In this dissertation, sparse processing of signals for directions-of-arrival (DoAs) estimation is addressed in the framework of Compressive Sensing (CS). In particular, DoAs estimation problem for different types of sources, systems, and applications are formulated in the CS paradigm. In addition, the fundamental conditions related to the ``Sparsity'' and ``Linearity'' are carefully exploited in order to apply confidently the CS-based methodologies. Moreover, innovative strategies for various systems and applications are developed, validated numerically, and analyzed extensively for different

Abstract:

Les réseaux sociaux numériques professionnels, qualifiés ici d’espaces numériques interstitiels à thématiques professionnelles (EIP) dans cette recherche, suscitent, en raison de leur nature émergente et ambivalente, des interrogations tant sur le plan empirique que sur le plan conceptuel. A partir des observations exploratoires menées avec une démarche inductive et qualitative sur les EIP spécialisés dans la gestion des ressources humaines de la fonction publique territoriale (FPT), cette recherche propose, d’une part, une conceptualisation systémique de l’analyse du fonctionnement des EIP, e
