A 7-step method (with 25 sub-steps) to assess risk of air pollutants is introduced. These steps are: pre-considerations, sampling, statistical analysis, exposure matrix and likelihood, doseresponse matrix and likelihood, total risk evaluation, and discussion of findings. All mentioned words and expressions are wellunderstood; however, almost all steps have been modified, improved, and coupled i...

%e explore possible muon-number-nonconserving processes in gauge theories in which the right-handed muon and electron appear along with neutral heavy leptons in SU(2) U(1) doublets. The same mechanism which gives a mass to the electron and muon is expected to mix the left-handed neutral leptons with the neutrinos. In the simplest case, this leads to a rate for p, ~ey 25 times larger than previo...

In recent works, we have studied linear predictive models constrained by time-domain filters. In the present study, we will study the one-dimensional case in more detail. Firstly, we obtain root-exchange properties between the roots of an all-pole model and corresponding constraints. Secondly, using the root-exchange property we can construct a novel matrix decomposition A RA = I, where R is a ...

The long chain has been an important concept in the design of flexible processes. This design concept, as well as other sparse designs, have been applied by the automotive and other industries as a way to increase flexibility in order to better match available capacities with variable demands. Numerous empirical studies have validated the effectiveness of these designs. However, there is little...

Recent work has emphasized the substantial benefits offered by easily searchable, digitized, two sided matching platforms through decreased search costs and reduction of market frictions, but paid relatively limited attention to their negative social welfare implications. In this paper we investigate if the availability of such platforms for the solicitation of casual sex has influenced the inc...

+ explain the implications of the ageing of our population for the prevalence and incidence of dementia + describe the different types of dementia and the difficulty in distinguishing between them + summarize the incidence and prevalence of dementia, regionally and worldwide + identify risk factors for the development of dementia + explain that dementia is associated with both disability and mo...

In the probabilistic approach tb uncertainty management the input knowledge is usually represented by means of some probability distributions. In this paper we assume that the input knowledge is given by two discrete conditional probability distributions, represented by two stochastic matrices P and Q. The consistency of the knowledge base is analyzed. Coherence conditions and explicit formulas...

background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...

Groups of Small and Medium Enterprises (SME) back each other and form guarantee network to obtain loan from banks. The risk over the networked enterprises may cause significant contagious damage. To dissolve such risks, we propose a hybrid feature representation, which is feeded into a gradient boosting model for credit risk assessment of guarantee network. Empirical study is performed on a ten...
