Cables have always been under consideration as a structural element because of important features such as large strength to weight ratios and long spans. Their equilibrium analysis is an important issue in this regard. But this analysis involves highly nonlinear equations arising from large deformations and material nonlinearity. Different methods have been under use for numerical analysis of s...

A hybrid method combining the FR conjugate gradient method and the WYL conjugate gradient method is proposed for unconstrained optimization problems. The presented method possesses the sufficient descent property under the strong Wolfe-Powell SWP line search rule relaxing the parameter σ < 1. Under the suitable conditions, the global convergence with the SWP line search rule and the weak Wolfe-...

There is a bewildering array of methods for estimating animal home ranges, including minimum convex polygons, bivariate ellipses, adaptive and fixed kernels, and even a Brownian bridge technique (Bullard 1991; Kernohan et al. 2001). Many people believe that the fixed kernel method using least-squares cross validation (LSCV) is the best approach currently available (Seaman and Powell 1996; Powel...

for calculation of the displacements of points in micro geodesy networks, it is essential to discover stable and unstable points. without knowing stable points, calculated displacements are due to datum deficiency. in this case, calculated displacements are not valid. there are two methods to discover stable and unstable points: a-congruency robust method b- l1 norm minimization in this study t...

In this paper, Hybridization of Cuckoo Search algorithm with Powell Search (HCSPS) is used to solve optimal reactive power problem. Cuckoo search (CS) has been recently projected as a population-based optimization algorithm and it is has so far been efficaciously applied in a variety of fields. The inertia weight of Levy flights is presented to balance the capability of global and local search....

Introduction Recently, organisations as well as academics have increasingly become aware of the need for organisations to co-operate in knowledge networks with partnering organisations that can also be seen as competitors. It is not longer just co-operation that can improve a firm’s global competitiveness, but firms will actually meet their competitors in such cooperations. Organisations need t...

For nearly two decades, restorative justice responses to youth offending have been in place in all Australian states and territories. During this time, a vast amount of research on restorative justice processes and their impact on participants has amassed. Results consistently demonstrate that participants in restorative justice processes report positive experiences and regard their justice pro...
