in this paper, a stochastic multi-depot multi-objective vehicle routing problem (vrp) is studied. based on observations in real-world problems, we develop an aspect of the problem, such as stochastic availability of routes. to solve the problem in this situation, a two-objective mathematical model is developed, in which the related objective functions are: (1) minimizing transportation costs an...

Statistical tolerance analyses are usually performed to ensure the functional capabilities of a product, which underlies deviations. Therefore, several tolerance analysis techniques are available, whereas the vector-chain-based tolerance analysis is well-known and widely used. However, this technique is limited concerning the consideration of geometrical deviations, like the deformation of part...

The paper presents: (1) a graph-based theoretical background to refactoring a correct heterogeneous meta-program into its k-stage representation; (2) the refactoring method; (3) refactoring experiments with tasks taken from different domains, including real world tasks, such as meta-programs to teach Computer Science (CS) topics using educational robots. Refactoring meta-programs by staging ena...

Effective learning merely does not imply manipulation of information, which is integrated into an existing knowledge base, but rather, directing attention to what one has assimilated, understanding relationship between new information and what is already known, understanding the process which facilitated this and being aware that something new has actually been learnt. This article deals with t...

context resilience can be seen as an adaption to stress, such as that caused by health problems or disease, that attenuates the negative effects of stress. the present research performed a systematic review and meta-analysis to study resilience scores among adults diagnosed with chronic physical diseases. evidence acquisition electronic databases, including persian language (scientific informat...

background praziquantel, an antischistosomal compound, is used as first-line drug for chemotherapy of schistosoma japonicum since 1984. in this article, we conducted a systematic review and mete-analysis to evaluate the efficacy and safety of different dosages of praziquantel (pzq) for treatment of schistosoma japonicum. evidence acquisition: a number of six articles published in peer-reviewed ...

abstract background: research shows that the age at menarche, as an essential element in the reproductive health of women, had been decreasing in the 19th and 20th centuries, and shows a huge variation across different countries. there are numerous studies performed in iran reporting a range of age at menarche. thus, this meta-analysis aimed to determine the overall mean age at menarche of the ...

Historically, demonic possession and act of spirits were suspected to explain the strange symptoms of epilepsy. Even nowadays, not all symptoms of epilepsy are clear. Some epileptic semiology's are very bizarre reflecting the little we know about human brain. Focal non motor seizures are subjective experiences. Frontal hyper motor seizures can be wrongly diagnosed as agitations. Absence attacks...

This paper investigates the development of an effective heuristic to solve the set covering problem (SCP) by applying the meta-heuristic Meta-RaPS (Meta-heuristic for Randomized Priority Search). In Meta-RaPS, a feasible solution is generated by introducing random factors into a construction method. Then the feasible solutions can be improved by an improvement heuristic. In addition to applying...

This paper is devoted to empirical investigation of novel multi-level ensemble meta classifiers for the detection and monitoring of progression of cardiac autonomic neuropathy, CAN, in diabetes patients. Our experiments relied on an extensive database and concentrated on ensembles of ensembles, or multi-level meta classifiers, for the classification of cardiac autonomic neuropathy progression. ...
