The motions of the airflow induced by the movement of an automatic guided vehicle (AGV) in a cleanroom are numerically studied by large-scale simulation. For this purpose, numerical experiments scheme based on domain decomposition method is designed. Compared with the related past research, the high Reynolds number is treated by large-scale computation in this work. A domain decomposition Lagra...

 This paper reports on a simple application of autonomous agents that cooperatively work in a multi-agent system trying to efficiently handle control in flexible manufacturing scenarios. The focus of the paper is on the simulation of scheduling and dispatching algorithms for automated guided vehicles (AGV) in flexible manufacturing systems (FMS). The paper presents a basic design management sy...

utomated guided vehicles (AGVs) have been operating effectively in factories for decades. These vehicles have successfully used strategies of deliberately structuring the environment and adapting the process to the automation. The potential of computer vision technology to increase the intelligence and adaptability of AGVs is largely unexploited in contemporary commercially available vehicles. ...

United States and European safety standards have evolved to protect workers near Automatic Guided Vehicles (AGV's). However, performance standards for AGV's and mobile robots have only recently begun development. Lessons can be learned from research and standards efforts for mobile robots applied to emergency response and military applications. Research challenges, tests and evaluations, and pr...

Automated Guided Vehicles (or AGVs for short) have become an important option in material handling. In many applications, such as container terminals, the service area is often arranged into rectangular blocks, which leads to a mesh-like path topology. Therefore, developing efficient algorithms for AGV routing on the mesh topology has become an important research topic. In this paper, we presen...

The treatment of refractory glaucoma (RG) is challenging. The commonly adopted strategy in RG treatment is a glaucoma drainage device (GDD) implantation, which despite its radical nature may not always provide the desired intraocular pressure (IOP) levels for a long term. This review is based on the scientific literature on Ahmed glaucoma valve (AGV) implantation for refractory glaucoma. The te...
