Fragility surfaces give the probability of failure for structural or non-structural systems as a function of two parameters, the earthquake magnitude and epicentral distance. These parameters provide a unique characterization of the ground motion. In contrast, the current characterization of the ground motion by a single parameter, e.g., the Peak Ground Acceleration (PGA), can be unsatisfactory...

The functional independence measure (FIM) is used to determine the degree of disability that patients experience and the progress that they make through programs of medical rehabilitation. Rasch analysis is a statistical technique for constructing interval measures from ordinal data that was applied to derive FIM measures. The major factors that are taken into account to produce FIM measures ar...

Despite all the recent work in the area of risk measurement, there is still a number of theoretical, as well as practical, questions left unanswered. The one we focus on in the present paper deals with the problem one faces when the maturity (horizon, expiration date, etc.) associated with a particular risky position is not fixed. We take the view that the mechanism used to measure the risk con...

Recently, due to the increasing importance of reducing severe vehicle accidents on roads (especially on highways), the automatic identification of road surface conditions, and the provisioning of such information to drivers in advance, have recently been gaining significant momentum as a proactive solution to decrease the number of vehicle accidents. In this paper, we firstly propose an informa...

Resource allocation problems are concerned with the allocation of limited resources among competing activities so as to achieve the best performances. However, in systems which serve many users there is a need to respect some fairness rules while looking for the overall efficiency. The so-called Max-Min Fairness is widely used to meet these goals. However, allocating the resource to optimize th...

a r t i c l e i n f o We investigate how team and individual performances of players in the National Basketball Association respond to variations in intra-team pay inequality. By breaking down team dispersion into conditional and expected components, we find that expected pay dispersion has a positive effect on team and individual performance. We find that team and individual performances are e...

Financial returns exhibit stylized facts such as leptokurtosis, skewness and heavy-tailness. Regarding this behavior, in this paper, we apply multivariate generalized hyperbolic (mGH) distribution for portfolio modeling and performance evaluation, using conditional value at risk (CVaR) as a risk measure and allocating best weights for portfolio selection. Moreover, a robust portfolio optimizati...
