The authors develop a system of differential equations describing the motion of the structural system equipped with DFP bearings. The Runge-Kutta numerical method, specifically the ode15s function in MATLAB, was used to solve these equations. The results of the calculations provide a comparison of the damping efficiency of the structural system with and without the use of DFP bearings, assessing the effectiveness of vibration isolation during an earthquake, with three components X, Y, and vertical considered.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

One of the easiest and efficient way of water conservation to solve drinking water scarcity is rooftop water harvesting. To evaluate the performance of the first flush with micromesh filter system, inflow and outflow of the rooftop water samples were analysed for pH, EC, TDS, SAL and TSS parameters. In general, the PH, electrical conductivity, and TDS of the roof water samples were within the drinking water standards and the first flush with micromesh filter system was found to reduce TDS values.

Feedback is an integral part of our lives. Try touching your fingertips with your eyes closed; you may not succeed the first time because you have broken a feedback loop that ordinarily “regulates” your motions. The regulatory role of feedback manifests itself in biological, mechanical, and electronic systems, allowing precise realization of “functions.” For example, an amplifier targeting a precise gain of 2.00 is designed much more easily with feedback than without.
