BACKGROUND The RD(50) (exposure concentration producing a 50% respiratory rate decrease) test evaluates airborne chemicals for sensory irritation and has become an American Society for Testing and Materials (ASTM) standard method. Past studies reported good correlations (R(2)) between RD(50)s and the occupational exposure limits, particularly threshold limit values (TLVs). OBJECTIVE The main ...

Given a sequence of n elements, the All Nearest Smaller Values (ANSV) problem is to nd, for each element in the sequence, the nearest element to the left (right) that is smaller, or to report that no such element exists. Time and work optimal algorithms for this problem are known on all the PRAM models 4, 6], but the running time of the best previous hypercube algorithm 9] is optimal only when ...

The paper examined the value system in Philippine firms against the backdrop of Eastern-Western cultural dynamics in East Asia. The Asian milieu presents co-existence of cultural stasis and unease -balance and tension between Eastern values and Western ideas. Successful Asian countries demonstrated their ability to blend conflicting cultures and highlight certain values in order to promote nati...

This paper develops a Bayesian analysis in the context of record statistics values from the two-parameter Weibull distribution. The ML and the Bayes estimates based on record values are derived for the two unknown parameters and some survival time parameters e.g. reliability and hazard functions. The Bayes estimates are obtained based on a conjugate prior for the scale parameter and a discrete ...

Threshold limit values (TLVs) are intended to protect workers from the severest effects of thermal stress and to establish the exposures to heat in working conditions. Earlier, acute heat strokes often occurred as a result of working in hot environments in Japan. However, acute heat strokes recently sometimes occurred in outdoor work environments such as industrial constructions and agriculture...

gerbillus nanus is a highly polytypic species exhibiting considerable geographical variation, both in external and cranial characters. in the present study, specimens were collected from different localities in the northeastern, eastern, central and southern iran. the values for external end cranial measurements have been given. the specimens present the existence of two different morphotypes o...

typographical data entry errors and incomplete documents, produce imperfect records in real world databases. these errors generate distinct records which belong to the same entity. the aim of approximate record matching is to find multiple records which belong to an entity. in this paper, an algorithm for approximate record matching is proposed that can be adapted automatically with input error...

In many record linkage applications, identifiers have to be encrypted to preserve privacy. Therefore, a method for approximate string comparison in private record linkage is needed. We describe a new method of approximate string comparison in private record linkage. The main idea is to store q-grams sets derived from identifier values in Bloom filters and compare them bitwise across databases. ...

The common property of these systems is that their internal data structure is twofold. On the one hand, they record the explicit shape of the current designed product. On the other hand, they record the identifiers of the entities that constitute the shape, the constraints between these entities and the input values involved in these constraints, thus recording a program. Providing new input va...
