[1] The concept of return period is fundamental for the design and the assessment of many engineering works. In a multivariate framework, several approaches are available to its definition, each one yielding different solutions. In this paper, we outline a theoretical framework for the calculation of return periods in a multidimensional environment, based on survival copulas and the correspondi...

As reverse logistics is a relatively new field in supply chain management, especially in Asia, a detailed study is conducted to understand the status of companies practicing reverse logistics to support their Asia Pacific operations. This paper discusses an empirical examination of a company performing reverse logistics in Asia with Singapore being the coordination hub with the United States (U...

This paper compares the synchronicity of individual stock returns in different countries. For the US, Morck et al (2000) and Campbell et al (2001) show that the US in the post war period experienced an increase in firm specific stock return variations and thus a reduction in synchronicity. We show that a similar international trend, albeit weaker, is visible for many countries. Using both regre...

The design rainfall intensity and its return period of the combined interceptor sewer is an important factor affecting overflow (CSO) occurrence. However, we often use ratio (or multiple, n0) to sewer, equivalent ignored. In this study, a low formula modeling method was proposed estimate period. First, new event separation approach especially developed, minimum interevent time (MIET) set concen...

abstract flood is among phenomena which result considerable damages to resources and is a serious issue among hydrologists. the proper estimation of runoff is necessary for designating appropriate approaches for its control or optimal management. various problems have been reported in application of empirical models. the regional analysis of runoff with different return periods by applying wate...

Landslides, floods and secondary floods (hereinafter called phenomena) triggered by rainfall and causing extensive damage are reviewed in this paper. Damaging Hydrogeological Events (DHEs) are defined as the occurrence of one or more simultaneous aforementioned phenomena. A method for the characterisation of DHEs based upon historic data is proposed. The method is aimed at assessing DHE-related...
