An accurate calibration of inertial measurement unit errors is increasingly important as the inertial navigation system requirements become more stringent. Developing calibration methods that use as less as possible of IMU signals has 6-DOF gimballed IMU in space-stabilized mode is presented. It is considered as held stationary in the test location incorporating 15 di...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

In this paper‎, ‎a computational approach is adopted for solving a multi-objective optimal control problem (MOOCP) formulation of optimal drug scheduling in human immunodeficiency (HIV) virus infected by individuals‎. ‎The MOOCP‎, ‎which uses a mathematical model of HIV infection‎, ‎has some incompatible objectives‎. ‎The objectives are maximizing the survival time of patients‎, ‎the level of D...

In this research, we study an optimal overhaul–replacement policy of a multi-degraded repairable system sold with a free replacement warranty. In the proposed replacement policy, a maintenance action and failure are dependent on a system degradation level and the system age, and hence the replacement model will provide more effective maintenance decisions. Failure of the system is modeled using...

A methodology for designing hybrid controllers for large scale, multiagent systems is presented. Our approach is based on optimal control and game theory. The hybrid design is seen as a game between two players: the control, which is to be chosen by the designer and the disturbances that encode the actions of other agents (in a multi-agent setting), the actions of high level controllers or the ...

Packet level measurement is now critical to many aspects of broadband networking, e.g. for guaranteeing Service Level Agreements, facilitating measurement-based admission control algorithms, and performing network tomography. Because it is often impossible to measure all the data passing across a network, the most widely used method of measurement works by injecting probe packets. The probes pr...

In this paper we describe methods applicable to the modeling and control of mechanical manipulation problems, including those that experience uncertain stick/slip phenomena. Manipulation in unstructured environments often includes uncertainty arising from various environmental factors and intrinsic modeling uncertainty. This reality leads to the need for algorithms that are not sensitive to unc...

Word prediction methodologies depend heavily on the statistical approach that uses the unigram, bigram, and the trigram of words. However, the construction of the N-gram model requires a very large size of memory, which is beyond the capability of many existing computers. Beside this, the approximation reduces the accuracy of word prediction. In this paper, we suggest to use a cluster of comput...

We consider nonlinear systems with input-to-output stable (IOS) unmodelled dynamics which are in the \range" of the input. Assuming the nominal system is globally asymptotically stabilizable and a nonlinear small gain condition is satissed, we propose a rst control law such that all solutions of the perturbed system are bounded and the state of the nominal system is captured by an arbitrarily s...
