Reduction

This paper proposes an efficient method to determine entire reducts of incomplete decision tables according to the relational database approach. In the complex case, this algorithm has exponential computational complexity. However, this algorithm has polynomial computational complexity in the different cases of databases.

This paper examines the types of fraud in the financial affairs of public corporations and the way they deal with them and ultimately the right to judicial review. The results of the investigations showed that after proving any crime and issuing a lower court judgment, there is a right for the offender to seek authority from the authorities in order to obtain a reduction in the punishment. The multiplicity of judicial procedures is a mechanism and tool for correcting a mistake or probable judicial error.

Responding to the needs of shareholders and investors, earning profit and income and covering current expenses are the hugest goals of each economic unit. Banks and financial institutions also have these rules. Perhaps the most important thing for them is calculating and understanding the cost of money.

This thesis explores the problem of wasteful fashion consumption in light of the current need for individuals to develop a sustainable way of living. The Agenda 21 report from the Rio Earth Summit (1992) determined that sustainable consumption is an issue to be addressed in terms of resource conservation, waste reduction and a reduction of production pollutants. To date, in Australia, there are no policies or strategies in place to reduce wasteful consumption from the consumer’s perspective and it is this research and policy deficit that this thesis research addresses.

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

The overall aim of this study is to determine the most effective way to reduce the radiation dose to the breast during non-breast related CT scans, whilst still maintaining a suitable image quality. This study will attempt to compare the doses and noise of various protocols that can be used for dose reduction, including tube current modulation, bismuth breast shields and manual reduction of tube current.

The main aims of the project were to firstly find out or identify barriers that are inhibiting builders from installing greywater systems and secondly to identify and formulate strategies to reduce or eliminate the barriers identified. The main barriers for builders are; high cost, government regulations, lack of builder awareness or knowledge, and low client demand.

Poverty and inequality are among the most discussed topics in Economics. This thesis aims to investigate the empirical relationship between financial inclusion, poverty and gender inequality. Using unique cross-country panel and survey data sets, three hypotheses are tested: (1) microfinance is an effective tool for poverty reduction; (2) women’s participation in microfinance contributes to improvements in gender equality; and (3) financial inclusion has a positive effect on household income in China.

In addition to the physical parameters such as magnetization intensity distribution, the volume and the shape of the magnetized material, directions of the magnetization and the ambient field, the distance between the observation surface and the causative sources significantly affects the shape and the amplitudes of the magnetic anomalies. Aeromagnetic surveys are performed using either a draped surface or a constant elevation plane above sea level. These surveys can easily reconnoiter large territories in a short time.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.
