PMO conceptualization for engineering and construction businesses

Over the last decade many organizations began to recognize that the implementation of Project Management (PM) practices was a necessity rather than an option. In order to improve the success of projects, organizations have been adopting specialized structures (normally called PM Offices or PMOs) that carry out the management of projects in a coordinated and centralized way. In recent years, several PMO models and functions have been proposed by many authors. The major challenge for most organizations is to decide which specific functions in a particular context should be implemented. In fact, PMO's roles and functions, though standardized and clearly defined in literature, vary in practice. The main goal of this research was to propose a set of functions for a supportive PMO in an engineering and construction company. For example, develop and implement a PM methodology, provide a set of tools to support PM, and develop PM competences.info:eu-repo/semantics/publishedVersio

Clifford Simulation: Techniques and Applications

Despite the widespread belief that quantum computers cannot be efficiently simulated classically, efficient simulation is known to be possible in certain restricted regimes. In particular, the Gottesman-Knill theorem states that Clifford circuits can be efficiently simulated. We begin this thesis by reviewing and comparing several known techniques for efficient simulation of Clifford circuits: the stabilizer formalism, CH form, affine form, and the graph state formalism. We describe each simulation method and give four different proofs of the Gottesman-Knill theorem. Next we review a recent work [15], which shows that restricting the geometry of Clifford circuits can lead to a further speedup. We give an algorithm for simulating Pauli basis measurements on a planar graph state in time $\widetilde{O}(n^{\omega/2})$, where $\omega < 2.373$ is the matrix multiplication exponent. This algorithm achieves a quadratic speedup over using Clifford simulation methods directly. As an application of this algorithm, we consider a depth-$d$ Clifford circuit whose two-qubit gates act along edges of a planar graph and describe how to sample from its output distribution or compute an output probability in time $\widetilde{O}(n^{\omega/2}d^\omega)$. For $d= O(\log n)$, both of these results are quadratic speedups over using Clifford simulation methods directly. Finally, we extend these simulation algorithms to universal circuits by using stabilizer rank methods. We follow a previously known gadgetization procedure [9] to show that given a depth-$d$ Clifford+$T$ circuit with $t$ $T$ gates and whose two-qubit gates act along edges of a planar graph, we can sample from its output distribution in time $\widetilde{O}(2^{0.7926t}n^{5/2}t^{6} d^3)$ and can compute output probabilities in time $\widetilde{O}(2^{0.3963t}n^{3/2}t^{6} d^3)$. Previous work [9,6], applied to the case $d=O(\log n)$, gives algorithms for sampling in time $O(2^{0.3963t} n^6 t^6)$ and computation of output probabilities in time $O(2^{0.3963t}n^3t^3)$. Our sampling algorithm offers improved scaling in $n$ but poorer scaling in the exponential term, while our algorithm for computing output probabilities offers improved scaling in $n$ with identical scaling in the exponential term

Rights and Representation: Media Narratives about Disabled People and Their Service Animals in Canadian Print News

Canadian news coverage is reflecting and shaping an evolution of thought about how we must publicly account for animals’ roles in the disability rights movement. Through a textual analysis of 26 news media articles published between 2012 and 2017, this research demonstrates that the media play a key role in reporting on discrimination, yet media narratives about service animals and their owners too often fail to capture the complexity of policies and laws that govern their lives. In Canada, there is widespread public confusion about the rights of disabled people and their service animals. This incertitude is relevant to both disability and animal oppression. This research identifies nine frames within the media narratives, as well as evaluating perspectives from critical animal studies in the news articles. These frames, which emerge in the media reports, in their descriptions of human and (less often) animal rights, illustrate public confusion surrounding these rights. The confusion is inevitable given the many laws in Canada that govern service animals. Thus, to give context to the news coverage, this article also surveys the legal protections for disabled people who use service animals in Canada, and suggests that until the news media understand the legalities surrounding service animals, they will not be well equipped to fulfil their role of informing the public. This is a lost opportunity in light of the media’s potential role as a pivotal tool to educate the public about disability and animal rights
