Abstract:

The subgradient projector plays an important role in convex optimization, since the subgradient projection algorithm is a classical method for solving convex feasibility problems. This motivates us to explore fundamental properties of the subgradient projector. One can define the subgradient projector of a convex function via a selection of the subdifferential operator. This opens the door to define the subgradient projector of nonconvex functions by using the Mordukhovich limiting subdifferential operator. This thesis offers a systematic study of the subgradient projector. First, motivated by

Abstract:

This work builds up on the greatest minds of Cambridge Holography: Adrian Cable, Edward Buckley, Jonathan Freeman, and Christoph Bay. Cable and Buckley, developed an OSPR algorithm which was the first to provide high-quality real-time hologram generation using general-purpose hardware while Freeman designed a method to correct arbitrary aberrations. As ingenious as the method was, the calculations were extensively lengthy. Addressing this issue, a variant of OSPR suited for correcting spatially-varying aberration is presented. The algorithm combines the approaches of Cable, Buckley and Freeman

Abstract:

The current established historiography of the field of project management dates back to the 1950s and there is little known about the development of this field prior to the Second World War. Critical scholars within this field have challenged the timeline for project management. This historical research provides evidence of project practices prior to the twentieth century by introducing the activities of projectors, who are currently unacknowledged within the field of project management. The title of projector was assigned to initiators and/or promoters of the idiosyncratic activities that com

Abstract:

The miniaturization of projection technology has enabled a new class of lightweight mobile devices with embedded projectors. Projection engines as small as a postage stamp are currently being embedded in thousands of mobile devices. Mobile projector-based devices differ in very fundamental ways from the display-based devices we commonly use. Mobile projectors can be carried with the user and project imagery into almost any space, projected content is visible to multiple users and supports social interaction, physical objects and surfaces can be augmented with projected content, and embedded pr

The Veo+ projector is using a cooling system that consists of fan and blowers. This system is cooling the electronic components of the device and the lamp of the projector, however extracting a high noise. To lower this noise the rpm speeds (rotational speed) of the fan and blowers should be decreased. Thus, lowering the speed will result in higher temperature values in whole system (inside the device). While lowering the speed, the higher temperature values should be kept within the thermal design specifications of the electronic components. The purpose of this thesis work is to find an optim

Abstract:

Quantum systems with variables in the ring Z(d) are considered, and the concepts of weak mutually unbiased bases and mutually unbiased projectors are discussed. The lines through the origin in the Z(d) x Z(d) phase space, are classified into maximal lines (sets of d points), and sublines (sets of d(i) points where d(i)vertical bar d). The sublines are intersections of maximal lines. It is shown that there exists a duality between the properties of lines (resp., sublines), and the properties of weak mutually unbiased bases (resp., mutually unbiased projectors).

Abstract:

<p>Quantum sl_3 projectors are morphisms in Kuperberg's sl_3 spider, a diagrammatically defined category equivalent to the full pivotal subcategory of the category of (type 1) finite-dimensional representations of the quantum group U_q (sl_3 ) generated by the defining representation, which correspond to projection onto (and then inclusion from) the highest weight irreducible summand. These morphisms are interesting from a topological viewpoint as they allow the combinatorial formulation of the sl_3 tangle invariant (in which tangle components are labelled by the defining representation) to be

Abstract:

碩士<br>國立臺灣大學<br>資訊工程學研究所<br>92<br>Over the past few years a considerable number of studies have been made on building large, high-resolution displays. The aim of this thesis is to build a seamless large-scale display system by tiling multiple projectors with the help of a pan-tilt-zoom camera. It adds to the display world by combining different techniques to create a large, high-resolution, and low-cost display system. This research takes two tasks into consideration when producing the seamless display: (1) the geometric calibration and (2) the photometric calibration. Here, I develop a vision

Abstract:

Yes<br>Random sets are used to get a continuous partition of the cardinality of the union of many overlapping sets. The formalism uses Möbius transforms and adapts Shapley's methodology in cooperative game theory, into the context of set theory. These ideas are subsequently generalized into the context of finite-dimensional Hilbert spaces. Using random projectors into the subspaces spanned by states from a total set, we construct an infinite number of continuous resolutions of the identity, that involve Hermitian positive semi-definite operators. The simplest one is the diagonal continuous res

Abstract:

碩士<br>國立高雄應用科技大學<br>機械與精密工程研究所<br>104<br>A compact projection system, using separated RGB LEDs as light sources, is designed mainly by cementing fly-eye arrays on the surfaces of X-cube prism, which is helpful for not only shrinking the system volume but also increasing the energy efficiency by reducing the reflection loss on optical surfaces. For constructing the initial first-order design of the illumination component, the focal lengths and dimensions of corresponding elements are solved by the optical invariant principle. The next step is to compare the influence on the uniformity for conde

Abstract:

碩士<br>國立中央大學<br>光電科學研究所<br>99<br>In this thesis, the modulations on LEDs driving current and duration ratio of RGB-LED-array as light source for pico-projector display were proposed. The light source that we use in this study is OSRAM LE ATB S2W. We perform our light source in consideration of three orientations, power consumption, brightness, and color temperature. Two designs for different projection types, low power-consumption and high brightness, are proposed. Both types are designed to achieve color temperature of 6500K. For a low-power-consumption type, the light source is able to suppl
