determination of the optimum loading path (internal pressure- axial feeding) to restrict the bursting, buckling and wrinkling through tube hydroforming process is necessary to produce an acceptable tube. in this paper, the wrinkling and fracture criteria are implemented to an finite element code devoted to the simulation of tube hydroforming processes. using the ansys parametric design language...

In this paper, we estimate the efficiency of Metropolitan, Municipal and District Assemblies (MMDAs) in Ghana, investigate impact fiscal decentralization on local public goods services delivery by MMDAs. Using data from composite budgets all 216 MMDAs, employ both non-parametric parametric frontier methods to carry out study. The results with regard our two indicators indicate that autonomy pro...

Nowadays, one of the most important topics in risk management of banks, financial, and credit institutions is credit risk management. In this research, the researchers used survival analytic methods for credit risk modeling in terms of the conditional distribution function of default time. As a practical task, the authors considered the reward credit portfolio of Tose'e Ta'avon Bank of Guilan P...

Considerable attention has been devoted to environmental assessment and monitoring, primarily by physical and biological scientists, and more recently by social scientists. However, population growth and global change have resulted in an imperative to assess the resiliency of the environment to adapt to large scale changes and to continue to produce goods and services for future generations (su...

Often the probability of responding depends directly on the outcome value. This case can be treated by postulating a parametric model for the distribution of the outcomes before nonresponse and a model for the response mechanism. The two models define a parametric model for the joint distribution of the outcomes and response indicators, and therefore the parameters of these models can be estima...

To manage the operation of modern single-use products, it is necessary to evaluate their preservation indicators as uncontrolled, non-repairable, and maintenance-free objects. Data for assessing its parameters are considered one-time censored samples with continuous monitoring, which does not correspond mode storage products during operation. Under conditions limited volumes samples, problemati...
