Ž . Fuzzy Cognitive Maps FCMs is a new approach in modelling the behaviour and operation of complex systems. FCMs are proposed to be used in the modelling of control systems and particularly in the modelling of the upper part or supervisor of a hierarchical control system. The description and the formulation of FCM are examined, moreover a process control problem is presented and its model and ...
In this paper, a fuzzy control strategy (FCS) for an anaerobic wastewater treatment process is proposed in order to reject large disturbances on input substrate allowing a high methane production. This strategy is composed of: i) a state observer, which is based on a principal components analysis (PCA) and Takagi-Sugeno (TS) algorithm; it is designed to estimate variables hard to measure: bioma...
Hierarchical carbon-nanotube (CNT)-based composites have significant potential to expand the performance and functionality of aerospace composite structures. Notably, circumferentially aligned CNT arrays have previously been grown on woven alumina filaments to form a "fuzzy fiber" reinforced plastic (FFRP) architecture with demonstrated improvements in interand intra-ply mechanical properties a...
supervisors have critical role in the provision of support in workplace. the present study examined degree of perceived supervisor support related to experienced physical symptoms and psychological distress among employees of isfahan steel company, isfahan, iran. the sample included of 189 employees of the company in 2011 who completed questionnaires about supervisor support, physical symptoms ...
Brief Abstract We review the issues involved in building a special-purpose chip for performing RSA encryption/decryption, and review a few of the current implementation efforts.
We used a rigorous case study methodology to examine one supervisory dyad's work together during one semester. We used the "best-worst" strategy of several recent researchers, multiple sources of qualitative and quantitative process data, and the perspectives both of the participants and of observers. A number of findings provide hypotheses to guide future research. For example. Session 2 was i...
The first line supervisor has been identified as having a critical role in the management of safety. This paper presents the results of a study that investigated the attitudes, behaviours and skills that influences of their subordinates level of safety. The majority of supervisors indicated that they had positive safety management attitudes and that they displayed high levels of positive safety...
A particular characteristic of a manufacturing system concerns the complexity and the presence of uncertainties along with the difficulties in building analytical models that capture the system in all its important aspects. Hence, simulation remains one of the most widely used tools to fill this need. The objective of this article is related to the potential improvement of computer simulation a...
The work we describe here is aimed at assisting out-patients affected by insulin dependent diabetes mellitus with an advisory/control algorithm. This advisory/control algorithm incorporates expert knowledge about the treatment of this disease by using Mamdani type fuzzy logic controllers to regulate the blood glucose level (BGL). We proposed two-level architecture for control system. The goal o...
introduction : students’ satisfaction of their supervisor is very important in the process of writing a thesis; while satisfaction is present, favorable outcomes could be expected. this study compared graduate students’ satisfaction of their supervisors from various departments. materials and methods: in this descriptive cross-sectional study conducted in 2013, 90 graduate students who had ente...
