Introduction: Some evidence demonstrates endogenous inhibitory pathways of pain involved in the interphase (phase between early and later phase) of the formalin test. We previously showed that swimming stress modulates the pain-related behaviors during the interphase of the formalin test. In this study, we evaluated the role of the endogenous opioid system in modulating nociceptive responses of...

The validity of run-time monitoring of system goals and requirements depends on both the completeness of the requirements, as well as the correctness of the environmental assumptions. Often specifications are built with an idealized view of the environment that leads to incomplete and inconsistent requirements related to non-idealized behavior. Worse yet, requirements may be measured as satisfi...

In this chapter we shall introduce a new and practical method for two-phase flow rate measurement, which is known as flow division and separation method. As its name suggested, a two-phase flow is measured by diverting a small fraction of the total stream to a division loop and metering it with the separation means. This method has been developed in Xi’an jiaotong university since the end of la...

A challenge for any enterprise is to ensure conformance of its business processes with imposed compliance rules. The latter may constrain multiple perspectives of a business process, including control flow, data, time, resources, and interactions with business partners. However, business process compliance cannot completely be decided at design time, but needs to be monitored during run time as...

in this paper, the driver with antiwindup and fuzzy high-performance and robust pi controller has been suggested for permanent magnet synchronous motor (pmsm). this controller is suggested for the design of the robust driver for three phase pmsm and the cost reduction of its control system. it’s useful for the industrial application and automation and ultimately speed control and the improvemen...

In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...

Control charts are powerful tools to monitor quality characteristics of services or production processes. However, in some processes, the performance of process or product cannot be controlled by monitoring a characteristic; instead, they require to be controlled by a function that usually refers as a profile. This study suggests employing exponentially weighted moving average (EWMA) and range ...

The ability to perform different tasks by a serial manipulator mounted on legged robots, increases the capabilities of the robot. The position/force control problem of such a robot in the stance phase with point contacts on the ground is investigated here. A target plane with known stiffness is specified in the workspace. Active joints of the legs and serial manipulator are used to exert the de...
