In this paper a method to extend discrete uninorms and nullnorms on the finite chain L = {0, . . . , n}, to uninorms and nullnorms defined on the set of discrete fuzzy numbers whose support is a set of consecutive natural numbers contained in L is presented. Some basic properties of discrete uninorms and nullnorms are preserved by this extension method and the structure of these kinds of aggreg...

Random-effects meta-analyses are very commonly used in medical statistics. Recent methodological developments include multivariate (multiple outcomes) and network (multiple treatments) meta-analysis. Here, we provide a new model and corresponding estimation procedure for multivariate network meta-analysis, so that multiple outcomes and treatments can be included in a single analysis. Our new mu...

A probabilistic approach for damage detection is presented using noisy incomplete input and response measurements that is an extension of a Bayesian system identification approach developed by the authors. This situation may be encountered, for example, during low-level ambient vibrations when a structure is instrumented with accelerometers that measure the input ground motion and structural re...

The spectrum of possible parameters of symmetric configurations is investigated. We propose some new constructions, mainly based on Finite Geometry and on extension methods. New parameters are provided, both for general symmetric configurations and for cyclic symmetric configurations. For several values of k, new upper bounds on the minimum integer E such that for each v≥ E there exists a (cycl...

We discuss the issue of conditioning on events with probability zero within an imprecise-probabilistic setting, where it may happen that the conditioning event has lower probability zero, but positive upper probability. In this situation, two different conditioning rules are commonly used: regular extension and natural extension. We explain the difference between them and discuss various techni...

Background. Chronic rotational instability of the knee after damage to the anterior cruciate ligament (ACL) fairly quickly produces undesirable secondary changes in the joint. Concomitant damage may affect the meniscus or the articular cartilage of the femoral condyle. The purpose of our study was to compare outcome in patients who had undergone one-stage surgical repair of damage to the ACL an...

this study examines iranian agricultural researchers’ attitudes regarding collaboration with extension workers and the variables associated with the researchers’ attitudes. data were obtained using a questionnaire developed by agricultural research centers of charmahal and bakhtiari, isfahan, safiabad and khuzestan in 1998. the findings re-vealed that the researchers’ attitudes towards collabor...

Understanding accumulated damage effects is essential when undertaking deep underground rock engineering, as complex in situ environments and intense engineering disturbances realistically affect the physical mechanical properties of rocks. Accumulated mainly causes extension micro-cracks sprouting specific defects rocks, altering microstructural parameters. In this investigation, loading unloa...
