Résumé :

Virtual machines are today at the core of a very large portion of the code that runs our everyday lives. Their relative performance and characteristics are of high significance for society indirectly and few other are as impactful as the JVM. In this thesis, we examine the possibility to speed up stack tracing on HotSpot and OpenJDK by implementing a return barrier. The barrier is implemented by overwriting the return program counter on the top frame with a function that re-installs itself on the frame below every time it’s executed. Because of this, the barrier acts as a “low water mark” and

Résumé :

This thesis examines the predictive ability of models for forecasting inflation and financial market volatility. Emphasis is put on evaluation of forecasts and the usage of large data sets. Variety of models are used to forecast inflation, including diffusion indices, artificial neural networks, and traditional linear regressions. Financial market volatility is forecast using various GARCH-type and high-frequency based models. High-frequency data are also used to obtain ex-post estimates of volatility, which is then used to evaluate forecasts. All forecast are evaluated using recently p

Résumé :

In fisheries, advice for the management of fish populations is based upon management quantities that are estimated by stock assessment models. Fisheries stock assessment is a process in which data collected from a fish population are used to generate a model which enables the effects of fishing on a stock to be quantified. This study determined the effects of various data sources, assumptions, error scenarios and sample sizes on the accuracy with which the age-structured production model and the Schaefer model (assessment models) were able to estimate key management quantities for a fish resou

Résumé :

Most empirical studies in nance use data on a daily basis which is obtained by retaining the last observation of the day and ignoring all intraday records. However, as a result of the increased automatization of nancial markets and the evolution of computational trading systems, intraday data bases that record every transaction along with their characteristics have been stablished. These data sets prompted the development of a new area of research ( nance with high frequency data), and in 1980 a literature based on the mechanisms of trading began (forms of trading, rules on securities

This research was mostly based on static linear models or derivatives thereof such as the Efficient Market Hypothesis, the Capital Asset Pricing Model and the Arbitrage Pricing Theory. This study project takes an interesting look at a contemporary capital market hypothesis, which is fundamentally based on a non-linear statistical model.

Résumé :

Small pelagics dynamics are characterised by extreme variability owing to environmental factors, fishing and natural mortality. Because of highly-fluctuating dynamics, it is difficult to evaluate the stock status through models. To assess these evaluation difficulties, a model comparison framework based on the Management Strategy Evaluation (MSE) approach has been developed and tested in the Gulf of Cadiz anchovy stock. We have used a minimum realistic model (MRM) as operating model, including well documented environmental drivers for this stock to simulate abundance indexes and catches, and

Résumé :

Dolphinfish (Coryphaena hippurus) is a pelagic species that is ecologically and commercially important in the western Atlantic region. This species has been linked to dominant oceanographic features such as sea surface temperature (SST) frontal regions. This work first explored the linkages between the catch rates of dolphinfish and the oceanography (satellite-derived SST, distance to front calculations, bottom depth and hook depth) using Principal Components Analysis (PCA). It was demonstrated that higher catch rates are found in relation to warmer SST and nearer to frontal regions. This

Résumé :

The role of inland fisheries as contributors to local and national economies in developing African countries is well documented. In South Africa, there is increasing interest in inland fisheries as vehicles for achieving national policy objectives including food security, livelihoods provision, poverty alleviation and economic development but there is surprisingly little literature on the history, current status, and potential of inland fishery resources. This lack of knowledge constrains the development of management strategies for ensuring the biological sustainability of these resources and

In all data sets investigated, no change in the value of the mark accounts for more that half the observations.
