On Smooth Isolated Curves in General Complete Intersection Calabi-Yau Threefolds
This dissertation studies existence/non-existence of smooth and isolated curves in general complete intersection Calabi-Yau (CICY) threefolds. There are three parts. In the first part, we use Knutsen's technique to prove some existence results on smooth isolated curves in general CICY threefolds. …

The role of training in the human resource department of the south african parliament
… evaluated for four main reasons. These are: The non-existence of a training policy, lack of funds, non-existence of trainers and poor evaluation. All these factors need more attention at both organisational and employees level. This study aims to identify the key obstacles for effective training. …

Estimation in Truncated Exponential Family of Distributions
… well known problem in statistical inference. The non-existence of the maximum likelihood estimator (m.l.e.) with positive probability in certain truncated distributions is not well known. To mention a few results in the literature:</p> <p>(i) Deemer and Votaw 1955 show that the maximum likelihood …

Identifying Perfect Nonlocal Games
This thesis is about nonlocal games. These “games” are really interactive tests in which a verifier checks the correlations that can be produced by non-communicating players. We study the class of commuting operator correlations: correlations which can by produced by players who make commuting …

New Methods for Finding Non-Left-Orderable and Unique Product Groups
… we present techniques for proving a group to be non-left-orderable or a unique product group. These methods involve the existence of a mapping from the group to R which obeys a left-multiplication criterion. By determining the existence or non-existence of such a mapping, the desired information …

The impact of transport infrastruture in the econolic growth of South Africa
… latter. On the contrary, the findings revealed a non-existence of causal relationship between economic growth and transport infrastructure (roadways and airways), though the theoretical framework demonstrates a link between them. The findings also revealed a non-existence of a causality …

An investigation of relationships between graph theory and coding theory
The problem of the existence of perfect and nearly perfect codes over finite alphabets is generalised in two directions. This thesis is concerned with the existence and combinatorial properties of completely regular codes in distance-regular graphs. One of the main tools is the generalisation of …

Countable inductive limits
… As an example we can consider the proof of the non-existence of a countably infinite dimensional metrisable barrelled space.

The Truncated Cauchy Distribution: Estimation of Parameters and Application to Stock Returns
… problem addressed in this dissertation is the existence and estimation of the parameters of a truncated Cauchy distribution. It is known that when a number of distributions with infinite support are truncated to a finite interval that the maximum likelihood estimator of the scale parameter …

Symbiotic: The Human Body and Constructs of Nature
… and interchangeable, and how they pertain to the non-existence of a pure natural world. Through sculpture, I explore the essence of these two entities by considering constructs of nature, as well as where the human body fits in within these categories.

Nullità e inesistenza del provvedimento amministrativo: profili statici e dinamici del rapporto alla luce del nuovo codice del processo
… to analyze the difference between invalid and non-existent case from a general perspective. With this goal in mind, I began this study and research analyzing the most reliable contribution of civil law. The initial approach, profoundly linked to civil law, was, in my opinion, necessary due to …

Negation and Aspect: A comparative study of Mandarin and Cantonese varieties
… Cantonese mau5 consistently offer a situation non-existent reading, while Mandarin bù and Hong Kong Cantonese m4 always involve a modality reading (habitual or volitional). Based on the relative distribution of negation and different types of adverbs, Chapter 4 suggests that all standard …

Multiple Solutions on a Ball for a Generalized Lane Emden Equation
… exponents involved and their consequences on the existence and non existence of radial solutions on a unit ball in n dimensions. We extend the analysis to the phase plane for a clear understanding of the behavior of solutions and the relationship between their existence and the growth of nonlinear …

Class and ethnicity : the politics and ideologies of the Greek community in South Africa, circa 1890-1924
… absence of intra-ethnic conflict stems from the non-existence of antagonistic social relations amongst different social strata of the same ethnic group. It also supports the .hypotheses that the diffusion of ideologies and politics predominating in the country of origin of the immigrants plays a …

Semilinear elliptic partial differential equations with the critical Sobolev exponent
… variational methods and results from linear and non-linear functional analysis are applied to solving certain types of semilinear elliptic partial differential equations (PDEs). The ultimate goal is to prove results on the existence and non-existence of solutions to the Semilinear Elliptic PDEs …
