This paper is about the relation between contrast and ‘prominent positions’ − i.e. onsets, stressed syllables, and root-initial syllables.1 A number of works have assumed that only one of the three logically possible relations between contrast and prominent positions exists: namely that contrasts in non-prominent positions are always a subset of those in prominent positions. This situation is i...

Predictive accuracy is the sum of two kinds of uncertainty–natural variability and modeling uncertainty. This paper addresses the quantification of predictive accuracy of complex simulation models from two perspectives. First, it recognizes that there is a difference between variability and modeling uncertainty; the former can not be reduced with more test information, while the latter can. We ...

Boolean games offer a compact alternative to normal-form games, by encoding the goal of each agent as a propositional formula. In this paper, we show how this framework can be naturally extended to model situations in which agents are uncertain about other agents’ goals. We first use uncertainty measures from possibility theory to semantically define (solution concepts to) Boolean games with in...

background: hyperbilirubinemia, or jaundice, is a life threatening disorder in newborns. it is a multifactorial disorder with many symptoms. generally, the physiological jaundice is the most prevalent type however in some regions pathological jaundice is also common. this review article focuses on a brief introduction to jaundice, its types and causes, measuring the bilirubin level, clinical ap...

background: in spite of being vital to save the patients' life, blood transition may be dangerous and even fatal, too the aim of this study was to investigate the side effects (complications) of blood transfusion in the educational hospitals of qazvin. m aterials and methods: this is a descriptive cross sectional and practical study that was carried out in 2010. in this study, all the patients ...

early prediction of ongoing hemorrhage may reduce mortality via the earlier delivery of blood products, adequate orientation of the patient in a dedicated highly specialized and trained infrastructure, and by earlier correction of acute traumatic coagulopathy. we identified 14 scores or algorithms developed for the prediction of ongoing hemorrhage and the need for massive transfusion in severe ...

a survey of tissue oxygenation differences in intensive care patients with blood transfusion     haghighimoghadamy [1] *, valizadeh ma [2] , feizi a [3]     received: 26 dec, 2011 accepted: 7 mar, 2012     abstract   background & aims : greater than 75% patient that hospitalized in intensive care units has anemia. blood transfusion in icu is not recently and about 40-70% patients in intensive c...

Real options modeling, which extends the ability of option pricing models to evaluate real assets, can be used to evaluate risky projects because of its capacity to handle uncertainties. This research utilizes possibility theory to represent private risks of a project, which are not reflected in the market and hence are not fully evaluated by standard option pricing models. Using a transformati...

| The introduction of a notion of independence in possibility theory is a problem of long-standing interest. The deenitions that have up to now been given in the literature face some diiculties as far as interpretation is concerned. Also, there are inconsistencies between the deenition of independence of measurable sets and possibilistic variables. After a discussion of these deenitions and the...
