Marking the path forward with milestones.

Milestones and the Future for Cooperative Extension

Milestones like the centennial of the Cooperative Extension system are significant in any organization. Milestones measure progress along a path, but can also give reassurances that travelers are on the right track. As Extension moves into the next century, we must continuously ask ourselves if it is focused and on the right path. What are some guiding principles that we need to follow? What ar...

A Flexible Integrated Forward/ Reverse Logistics Model with Random Path-based Memetic Algorithm

Due to business and environmental issues, the efficient design of an integrated forward/reverse logistics network has recently attracted more attention from researchers. The significance of transportation cost and customer satisfaction spurs an interest in developing a flexible network design model with different delivery paths. This paper proposes a flexible mixed-integer programming model to ...

Backward and forward path following control of a wheeled robot

A wheeled mobile robot is one of the most important types of mobile robots. A subcategory of these robots is wheeled robots towing trailer(s). Motion control problem, especially in backward motion is one of the challenging research topics in this field. In this article, a control algorithm for path-following problem of a tractor-trailer system is provided, which at the same time provides the ab...

Path Following and Velocity Optimizing for an Omnidirectional Mobile Robot

In this paper, the path following controller of an omnidirectional mobile robot (OMR) has been extended in such a way that the forward velocity has been optimized and the actuator velocity constraints have been taken into account. Both have been attained through the proposed model predictive control (MPC) framework. The forward velocity has been included into the objective function, while the a...
