A modeling method for representing belt object deformation is proposed. Deformation of belt objects such as film circuit boards or flexible circuit boards must be estimated for automatic manipulation and assembly. In this paper, we assume that deformation of an inextensible belt object can be described by the shape of its central axis in a longitudinal direction called “the spine line” and line...

this paper presents a gaussian radial basis function neural network based on sliding mode control for trajectory tracking and vibration control of a flexible joint manipulator. to study the effectiveness of the controllers, designed controller is developed for tip angular position control of a flexible joint manipulator. the adaptation laws of designed controller are obtained based on sliding m...

We introduce the notion of a flexible 2 -cell and use it to define invariants – link groups – of 4 -manifolds. Flexible cells combine some features of both surfaces and handlebodies, therefore the link group λ(M) measures certain aspects of the handle structure of a 4 -manifold M . This group is a quotient of the fundamental group, and we construct examples of manifolds M with π1(M) 6= λ(M) . M...

this article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. the objective is to minimize the makespan for a given set of jobs in the system. this problem class is np-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. a number of test problems are randomly ge...

H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

this article is arranged based on a research plan which its goals is evaluation of the possibility of applying flexible human resource structure in industrial organizations. in this research, applying conditions of just in time (j.i.t) and flexible manufacturing systems (f.m.s) have brought up as a pioneer flexible movements in industrial units and based on based two phenomenon, the nescessity ...

conclusions temperaments can provide a basis to classify psychiatric disorders. psychiatric disorders can be placed in a spectrum based on temperaments. results four groups of temperaments were identified: high active, high flexible; high active, low flexible; low active, low flexible; and low active, high flexible. when temperament deteriorates personality, non-psychotic, and psychotic psychia...

We present the conceptual basis and a prototypical implementation of a software framework for syntactical and semantical similarities between ontology instances. Our focus comprises both the implementation of specific, ontology-based similarity measures and their flexible, efficient, and extensible combination.
