Semantically-Driven Flexible Division in Fuzzy Object Oriented Models

چکیده
Fuzzy Databases have been a fertile research area that has produced a wide variety of remarkable solutions for the storage and manipulation of imperfect information. Proposals can be found in the three most relevant data models: relational, object-oriented, and object-relational. Query capabilities have been especially studied in the context of the relational data model, while in object models many problems continue being a matter of research. In this paper, we focus on the resolution of “division queries” (in its relational sense) in an object oriented data model. As we will see, the presence of fuzzily described objects in the database make necessary to use suitable operators that take into account the resemblance that governs the comparison in the underlying reference universe. We also analyze the role of cardinality in this kind of queries. Keywords— Division, Quotient, Fuzzy, Object-Oriented, ObjectRelational, Database.

Integer-order Versus Fractional-order Adaptive Fuzzy Control of Electrically Driven Robots with Elastic Joints
Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...
متن کاملManipulation Control of a Flexible Space Free Flying Robot Using Fuzzy Tuning Approach
Cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. During such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. Therefore, to design and dev...
متن کاملA new non oriented models for calculating the efficiency of decision-making units in the presence of flexible variables
In assessing the relative efficiency of decision-maker units by classical Data Envelopment Analysis (DEA) models, the status of the data is determined from the input or output points of views. In real issues, there are some data whose statuses are debatable. Some decision making units consider them as input to achieve higher efficiency while some other decision making units consider them ...
