the efficiency measurement is a subject of great interest. the majority of studies on dea models have been carried out using radial or non-radial approaches regarding the application of dea for the efficiency measurement. this paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

there are many situations for statistical process in which we have both random and vagueinformation. when uncertainty is due to fuzziness of information, fuzzy statistical control charts play animportant role in the monitoring process, because they simultaneously deal with both kinds of uncertainty.dealing with fuzzy characteristics using classical methods may cause the loss of information and ...

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...

background and aim: approaches to professional health care have changed along with changes in health measures and progression of chronic diseases. patient participation is an international golden standard in new nursing paradigm. despite the importance of patient participation and its routine usage in professional care, this concept is not clear, especially in social and cultural context of ira...

a bstra ct     background: patients’ compliance to treatment is an important indicator for evaluating the successful management in chronic illnesses. despite the fact an applicable definition of compliance is required to suitable intervention and research, this concept is not clear and there is no consensus concerning its meaning, definition, and measurement. the aim of this study was to explor...

The analysis, veri cation, and control of hybrid automata with nite bisimulations can be reduced to nite-state problems. We advocate a time-abstract, phasebased methodology for checking if a given hybrid automaton has a nite bisimulation. First, we factor the automaton into two components, a boolean automaton with a discrete dynamics on the nite state space B and a euclidean automaton with a co...

Hybrid automata are a powerful formalism for modeling and verifying hybrid systems, that combine continuous and discrete behavior. A common problem for hybrid systems is the good parameters problem, which consists in identifying a set of parameter valuations guaranteeing a certain good behavior of a system. We introduce here HyMITATOR, a tool for efficient parameter synthesis for hybrid automat...

introduction : due to the importance of laser light penetration and propagation in biological tissues, many researchers have proposed several numerical methods such as monte carlo, finite element and green function methods. among them, the monte carlo method is an accurate method which can be applied for different tissues. however, because of its statistical nature, monte carlo simulation requi...

abstract. in this paper, we implement numerical solution of differential equations of frac- tional order based on hybrid functions consisting of block-pulse function and rationalized haar functions. for this purpose, the properties of hybrid of rationalized haar functions are presented. in addition, the operational matrix of the fractional integration is obtained and is utilized to convert compu...
