In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...

Recent rapid technological advances (including high-capacity fiber-optic cables) in the telecommunications industry have introduced numerous opportunities for services other than traditional voice transmission. Disruptions in service for these high capacity systems can be (and have been) disastrous. For these reasons, network reliability is critical. This thesis studies the problem of topologic...

based on the notion of micro-structure in linear elasticity presented by mindlin, a newextended continuum mechanics (ecm) formulation is derived which can be utilized to model thematerial behavior at atomic scale. an attempt has been made to present a formulation capable ofproducing the molecular dynamics (md) simulation results with less computational effort. to thisend, some new kinematical v...

Aetideidae is a calanoid copepod family dominant in the mesopelagic layer of Arctic Ocean for which little ecological information available because species identification, especially early copepodite stages, difficult. In this study, we developed identification flow whole stages five sympatric aetideid copepods ( Chiridius obtusifrons , Gaetanus tenuispinus G. brevispinus Aetideopsis minor and ...

Abstract. Radiosonde descent profiles have been available from tens of stations for several years now – mainly Vaisala RS41 radiosondes. They compared with the ascent profiles, ECMWF short-range forecasts and co-located radio occultation retrievals. Over this time, our understanding data has grown, comparison also shed some light on radiosonde data. The fall rate is very variable an important f...

The paper is focused on the equations of the optimal guidance for planar Lunar ascent. We point out some computational and graphical aspects.

In this article, we obtained a formula in close form for the multivariate generating function of {A(n,d,j)}n,d,j, where A(n,d,j) denote number permutations length n with d descents and j as first letter. addition to this, by series calculations generatingfunctionology, confirm recent enumerative conjecture Wang Zhang ballot permutations, which are any prefix descent is not more than ascent numb...
