Risk evaluation model for radiation protective countermeasures based on fuzzy entropy weight
On the basis of establishing a risk assessment index system, a model for assessing the risk of radiation protective countermeasures is proposed by introducing a fuzzy mathematics method and entropy weight theory, and the risk order of the radiation protective countermeasures is ranked by their entropy weight coefficients, which solves the decision problem of uncertain and fuzzy indexes in the risk assessment index system and could provide the decision-making basis for commanders in the process of nuclear accident rescue. The illustrative case study shows that the model could use the inherent information of the indexes adequately, and makes risk assessment for radiation protective countermeasures more reasonable, practicable and scientific.
Fuzzy and Hierarchy Decision Model for Nuclear Power Station Accident Emergency and its Application
Considering the complexity in the decision-making at nuclear power station accident emergency, an optimization model for the nuclear accident emergency scheme is established with the application of hierarchic analyzing and fuzzy decision and the comprehensive analysis of multiple objectives for the decision-making. The model has been used in one real emergency decision-making, and the result shows that its reasonableness and operability has been improved.
List of the described Coleoptera ofTasmania.
The Coleoptera of Tasmania have never been considered as 
a whole since the time of Erichson, and no list or 
catalogue of the species has ever been compiled. About 
10,000 species have now been recorded from Australia and 
Tasmania, of which scarcely 400 have been described from 
Tasmania. A very imperfect knowledge of what species 
are confined to the island exists, as species supposed only 
to occur there, are constantly being found in Victoria and 
New South Wales, and even sometimes in Western Australia 
and Queensland; on the other hand, Tasmanian 
collectors frequently obtain mainland species which have 
never been recorded from Tasmania. 
I have considered it advisable, therefore, to prepare a 
list of the species hitherto recorded from Tasmania, adding 
to the list such species as I have seen in Tasmanian collections, 
or have myself taken in Tasmania. In this list, 
the genera and families are placed as far as possible in the 
order in which they appear in Masters' "Catalogue of the 
Described Coleoptera of Australia;" the species are placed 
alphabetically. All known synonyms have been omitted.
