Practical formation stabilization control problems of multiple nonholonomic mobile robots have been considered in this paper. Cascaded structure of nonholonomic mobile robot system has been incorporated in the design of formation controllers. Some external perturbing signals have been injected into the consensus protocols of each robot's direction to overcome the uncontrollability of nonholonomic...
Online reputation has been proved to build trust and decrease uncertainty by prior studies with survey, panel, and experiment data. Aiming to directly measure reputation value, we adopted famous Becker-DeGroot-Marschack (BDM) auction procedure in economics to elicit subject's true willingness to pay (WTP) for product in a three-stage behavior experiment. The image of five-crown and five-heart, neither...
Time-bound hierarchical key management mechanisms are widely discussed in several environments and applications. Obviously, the collusion attacks are the serious problems in the time-bound hierarchical key management schemes. In the collusion attacks, two or more users assigned to some classes in distinct time periods collude to compute a key to which they are not entitled. Two kinds of countermeasures,...
Transformational leadership is viewed as "universal across cultures", but "the way it exert influence are culturally specific".

State Estimator (SE) relies on measurements for good solution. Whenever measurements are not available due to loss of telemetry there is a need to substitute those measurements with some pseudo measurements. Further, in situations where it is not possible to have a measurement there is a need for pseudo measurements to improve the observability in SE. This paper explains the experiences of using the...
