Abstract:
Finding a portfolio strategy that entails optimal performance and risk diversification may be a complicated task for investors. In this thesis, we explore and evaluate the performances of several non-trivial portfolio optimization strategies, based on various measures of risk, to identify the optimal choice. Furthermore, as in contemporary papers, we will also assess whether or not trivial strategies are outperformed by those that rely on rigorous theoretical frameworks. These portfolio strategies were backtested on historic U.S. stock marketdata ranging from 2000 to 2015, to evaluate how they

Abstract:
Adaptive filters constitute an important part of signal processing. They are widely used in many applications where signal statistics are unknown to the users. One of the most popular adaptive methods is known as the least mean-squared (LMS) algorithm. It is well known for its hardware simplicity and its cost effectiveness. However, the LMS adaptive algorithm does not operate well in non-ideal environments. Leakage in the updated equation of the LMS algorithm was proven to overcome many such problems. This algorithm is known as the leaky LMS (LLMS). The LLMS is very robust to drifting phenomen

This paper investigates the effect of parameter selection for the decision feedback equalization (DFE) on communication performance through a dispersive underwater acoustic wireless channel (UAWC).

The output from the MMSE-DFE is input to the decoder to estimate the transmitted bit sequence. The main goal of this experimental simulation is to determine the best selection, such that the reduction in the computational overload is achieved without altering the performance

Abstract:
The emergence of closed-loop Brayton cycle power plants, such as the PBMR, resulted in the need to simulate start-up transients for industrial multi-stage axial flow compressors operating at subsonic conditions. This implies that the delivery pressure and power requirements must be predicted for different mass flow rates and rotational speeds while operating in the first and fourth quadrants on the compressor performance charts. Therefore, an analytical performance prediction model for subsonic multi-stage axial flow compressors had to be developed that can be integrated into a generic network

Abstract:
Millimeter-wave systems introduce a set of particular severe requirements from the antenna point of view in order to achieve specific performances. In this sense, high directive antennas are required to overcome the huge extra path loss. Moreover, each particular application introduces additional requirements. For example, in very high throughput (VHT) wireless personal area networks (WPANs) communication systems at 60 GHz band beam-steering antennas are needed to deal with high user random mobility and human-body shadowing characteristic of indoor environments. Similarly, beam-steering capabi

Abstract:
This dissertation mainly consists of three parts. The first part proposes generalized linear minimum mean-square error (GLMMSE) estimation for nonlinear point estimation. The second part proposes a recursive joint decision and estimation (RJDE) algorithm for joint decision and estimation (JDE). The third part analyzes the performance of sequential probability ratio test (SPRT) when the log-likelihood ratios (LLR) are independent but not identically distributed. The linear minimum mean-square error (LMMSE) estimation plays an important role in nonlinear estimation. It searches for the best esti

Thesis (MScAgric)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: This research study consists of three investigations with regard to ostrich (Struthio camelus var. domesticus) production, meat quality and the processing of ostrich meat into a value added meat product. The first study was conducted in order to establish whether the gradual replacement of soybean oilcake meal with cottonseed oilcake meal (CSOCM) as a protein source in the diet of slaughter ostriches would affect ostrich growth performance and meat quality. A total of 105 ostriches were divided into five feeding grou

Cette thèse porte sur la modélisation et l'evaluation d'algorithmes de transfert de charge dans des systèmes parallèles et/ou distribués. Après une synthèse des différentes approches possibles du transfert de charge et des problèmes rencontres pour leurs mises en oeuvre et leurs évaluations quantitatives, nous développons plusieurs modèles basés sur une évolution markovienne de la configuration des charges de l'ensemble des processeurs. Les indices de performance étudiés afin de comparer les valeurs obtenues avec transfert et sans transfert sont la saturation mémoire, le débit du système, la c

Abstract:
Active Queue Management (AQM) schemes are used for ensuring the Quality of Service (QoS) in telecommunication networks. However, they are sensitive to parameter settings and have weaknesses in detecting and controlling congestion under dynamically changing network situations. Another drawback for the AQM algorithms is that they have been applied only on the Markovian models which are considered as Short Range Dependent (SRD) traffic models. However, traffic measurements from communication networks have shown that network traffic can exhibit self-similar as well as Long Range Dependent (LRD) pr

Abstract:
Sage Bharata’s ancient Indian aesthetic theory of “Rasa” has for many years been the subject of research and intercultural exploration in global theatre and performance studies. While this dissertation focuses on the role of observer in performance, it more importantly explores the larger notion of consciousness. Illuminated by “Rasa” theory, this research sifts through the understanding of broader philosophical, spiritual and aesthetic issues that are so often not cohesively examined within the context of performance studies. European and Asian philosophies are linked to once again examine co

Software development is an area in which companies not only need to keep up with the latest technology, but they additionally need to continuously increase their productivity to stay competitive in the industry. One company currently facing these challenges is Storytel - one of the strongest players on the Swedish audiobook market - with about a fourth of all employees involved with software development, and a rapidly growing workforce. With the purpose of understanding how the Storytel Tech Department is performing, this thesis maps Storytel’s productivity defined through the Four Key Metrics
