Opis:
Today’s companies are able to automate the enforcement of Environmental, Health and Safety (EH&S) duties through the use of workflow management technology. This approach requires to specify activities that are combined to workflow models for EH&S enforcement duties. In order to meet given safety regulations these activities are to be completed correctly and within given deadlines. Otherwise, activity failures emerge which may lead to breaches against safety regulations. A novel domain-specific workflow meta data model is proposed. The model enables a system to detect and predict activity failures through the use of data about the company, failure statistics, and activity proxies. Since the detection and prediction methods are based on the evaluation of constraints specified on EH&S regulations, a system approach is proposed that builds on the integration of a Workflow Management System (WMS) with an EH&S Compliance Information System. Main principles of the failure detection and prediction are described. For EH&S managers the system shall provide insights into the current failure situation. This can help to prevent and mitigate critical situations such as safety enforcement measures that are behind their deadlines. As a result a more reliable enforcement of safety regulations can be achieved.

Opis:
A model-based controller architecture for Fault-Tolerant Control (FTC) is presented in this paper. The controller architecture is based on a general controller parameterization. The FTC architecture consists of two main parts, a Fault Detection and Isolation (FDI) part and a controller reconfiguration part. The theoretical basis for the architecture is given followed by an investigation of the single parts in the architecture. It is shown that the general controller parameterization is central in connection with both fault diagnosis as well as controller reconfiguration. Especially in relation to the controller reconfiguration part, the application of controller parameterization results in a systematic technique for switching between different controllers. This also allows controller switching using different sets of actuators and sensors.

Opis:
The standard Bond method is the most acceptable method for designing and selecting ball/rod mills described by their basic parameter called work index (Wi). The standard Bond method is a tedious time consuming procedure requiring at least 7 – 10 grinding cycles, so that many researchers have tried to simplify this method to be able to perform a rapid calculation of a work index. This study aims to develop a new approach toward estimating the Bond ball mill work index (BBWI) by applying a series of kinetic grinding tests with Bond standard mill. Establishing a series of relationships between grinding parameters and Bond equation parameters, this approach is fast and practical due to eliminating laboratory control steps while reducing the number of milling steps. In this scope, thirteen ore samples were used to compare Wi values obtained by standard Bond method with those of the proposed kinetic approach. The kinetic periods were determined as 0.33, 1, 2, 4 and 8 minutes. The results of kinetic tests were found to be logical and acceptable as they were so close to the values obtained by Bond standard method, for all samples error was ≤ 2.60%. It was therefore concluded that the proposed approach could be considered as a simple yet practical alternative for the standard Bond method.

Opis:
We consider the Hamiltonian of a three-electron quantum dot composed of parabolic confinement plus the Coulomb terms. Instead of using the Jacobi coordinates, we apply a unitary transformation to this system. To avoid the complexity, the Taylor expansion of the effective potential is introduced into the problem and thereby a solution is found for the eigenvalues of the corresponding three-body Schrödinger equation in terms of the Wigner parameter.

Opis:
The main objectives of the article are connections between geomorphologic conditions and hydrogenous sites in the Kurpie-Mazurian outwash. The analysis of different kinds of connections allows to specify four hydroecologic systems referring to hydrological feeding types. The first system is connected with topogenous type of hydrological feeding widespread in outwash plains. Wetland areas mostly of the post lacustrine origin are situated in geomorphologically diversified, shallow melt-out depressions. The second system is connected with river valleys and with fluviogenous type of hydrological feeding. Fluvial processes significantly modify water conditions in the outwash. As a consequence of modification the movement of ground water increases and also hydrogenous sites diversify. The third system is connected with soligenous type of feeding. It is situated in the neighbourhood of dune areas. The last system of the hydrogenic sites is formed by ombrogenic type of hydrologic feeding. Those peatlands are usually situated in drainless depressions in dune areas and watersheds. The analysis of diversity of hydrogenous sites in the outwash area with relatively homogenous lithologic conditions indicates that prevailing topogenous type of hydrological feeding is transformed locally by the presence of dunes and rivers. Geomorphologie and hydrographic factors are very important in modification of water conditions as well as in formation of hydroecologic systems.
