In this research paper, an adaptive sliding controller designed to enhance seismic response mitigation in structural systems with prescribed performance is presented. Through comprehensive theoretical analysis and simulation studies, the efficiency of the performance function has been simulated for a one-degree-of-freedom structure.

For plate bending problems, using a plate theory to model thin plate structures is less computationally expensive than 3D modelling. The Kirchhoff-Love plate theory is appropriate for analysing thin plate structures. If the membrane deformation is ignored in the KirchhoffLove plate, each node has only one degree of freedom – the deflection.

The motion equation of a one-degree-of-freedom system when subjected to earthquakes is usually not solved by analytic methods. This problem can only be solved through the time step method, when integrating differential equations. This paper is devoted to presenting a numerical solution for a seismic analysis problem of a highway bridge pier with high damping rubber bearings under earthquakes.

The equations of state of asymmetric nuclear matter (ANM) starting from the effective potential in a one-loop approximation is investigated. It was showen that chiral symmetry is restored at high nuclear density and the liquid-gas phase transition are both strongly influenced by the isospin degree of freedom.

Recently, conventional logistic maps have been used in different vital applications like modeling and security. However, unfortunately the conventional logistic maps can tolerate only one changeable parameter. In this paper, three different generalized logistic maps are introduced with arbitrary powers which can be reduced to the conventional logistic map. The added parameter (arbitrary power) increases the degree of freedom of each map and gives us a versatile response that can fit many applications.

Computing the optimal geometric structure of manipulators is one of the most intricate problems in contemporary robot kinematics. Robotic manipulators are designed and built to perform certain predetermined tasks. There is a very close relationship between the structure of the manipulator and its kinematic performance. It is therefore important to incorporate such task requirements during the design and synthesis of the robotic manipulators.

Timber is highly anisotropic. It behaves differently in diverse directions. Tension and compression perpendicular to the grain present a low strength with respect to the ones parallel to the grain. To compensate for the lack, the self-tapping screw is an excellent choice for reinforcing the timber. This paper focuses on the notched timber beam with the experimental and numerical results. In the first part, the experimental results of the unreinforced notched beams and the screw reinforced notched beams under bending load will be presented.

The paper presents the analysis of some two-degree-of-freedom nonlinear systems under random excitation using Local Mean Square Error Criterion which is an extension of Gaussian Equivalent Linearization. The results obtained shows that the new technique can be very efficiently used not only for simple-degree-of-freedom systems as presented in the previous papers, but also for multi-degree-of-freedom ones.

In this paper, the formulation of a new six-node solid–shell element denoted (SHB6) is proposed. This prismatic element is based on a purely three-dimensional approach, and hence has displacements as the only degrees of freedom. A reduced integration scheme is adopted consisting of one-point in-plane quadrature and an arbitrary number of integration points, with a minimum number of two, distributed along the ‘thickness’ direction.

Starting in the 1980s, Nobel economist Milton Friedman played an important role, along with many other economists and public pol- icy experts, in the development of an index of economic freedom that would allow researchers to be able to measure the degree to which a country had a free market economy. Those efforts culminated in the Fraser Institute’s publication in 1996 of the first edition of Economic Freedom of the World. There have been 14 more editions published since then in what is now an annual series.

Given a particular representation of f described in Section 2.1,wemust then choose the amount of smoothness to allow for f . We examine model selection approaches that have already been used extensively by investigators in the area of time series modelling of air pollution and health data. A general strategy is to use a data-driven method and to select the number of degrees of freedom(df) which optimizes a particular criterion. For example, one approach is to choose the df which leads to optimal prediction of the mortality outcome series (e.g.

First we look up on the economic dependency as a component of economic deprivation. The dependency status of a person identified as an indicator of freedom and autonomy of an individual that reflects on the ability to transform his capability to the wellbeing (Sen 1992). The studies of the wellbeing of the elderly gives that there is high degree of dependency in the old age for both economic and Physical (Omran 1982, World Bank 1994). In the developed world, it is protected by the intuitional and social care that one way curtails the incidence of the dependency (Heslop, A. and...

Even though actual stock returns do not verify Assumption 1, it is an acceptable first-cut approximation. This means that we abstract from lead-lag effects (Lo and MacKinlay, 1990), nonsynchronous trading (Shanken, 1987), and autoregressive conditional heteroskedasticity (Bollerslev, Engle and Woooldridge, 1988). Note that most of the current estimators for the covariance matrix of stock returns also use this assumption. Future research will be devoted to relaxing it.
