Purpose To compare the intraocular pressure (IOP) outcomes of Ahmed glaucoma valve (AGV) surgery alone versus AGV with fluocinolone implant in uveitic glaucoma patients. Methods We identified uveitic glaucoma patients with AGV surgery alone and AGV surgery combined with fluocinolone implant from the Massachusetts Eye and Ear Ocular Inflammation Database. Demographic information, visual acuity...

PURPOSE To evaluate whether a combination of penetrating keratoplasty (PKP) or pars plana vitrectomy (PPV) and Ahmed glaucoma valve (AGV) implantation affords a level of success similar to that of AGV implantation alone. METHODS Eighteen eyes underwent simultaneous PPV and AGV, 14 eyes with PKP and AGV and 30 eyes with AGV implantation alone were evaluated. Success was defined as attainment o...

We designed and implemented a fork-type automatic guided vehicle (AGV) with a laser guidance system. Most previous AGVs have used two types of guidance systems: magnetgyro and wire guidance. However, these guidance systems have high costs, are difficult to maintain with changes in the operating environment, and can drive only a pre-determined path with installed sensors. A laser guidance system...

In multi AGV (Automatic Guided Vehicle) system, the core problem is how to plan a collision free path for each AGV, to solve the conflict between AGV and ensure the path of the path is not only the premise of path planning, but also the basis of the effectiveness of the task scheduling, so for the study of AGV system, multi AGV collision problem is also the research’s hotspot and difficult prob...

This paper focuses on the design of a highly efficient Automated Guided Vehicle (AGV) transportation system. Therefore, we attempt to construct detailed system management models that include agent cooperation, container storage scheduling, and container transportation planning. We then optimally design systems that are constructed with the use of these management models. The systems are compare...

AGV systems are now becoming widely used in automatic material handling systems. One of the issues arising in applications is routing. This paper presents a bi-directional path layout and an algorithm for routing AGVs without conflicts. Mathematical relationships among certain key parameters of path and vehicle are derived to minimize the space requirements of the layout. The routing efficiency...

Automated Guided Vehicle (AGV) systems have been frequently used as material handling equipment in manufacturing systems since the last two decades. The use of AGV systems has taken attention of practitioners and researchers. Although there are numerous studies concerning with AGV systems in literature, a few of them deal with the adaptation of these systems into JIT systems. Moreover, the faci...

We describe parallel simulations of an Automated Guided Vehicle (AGV) system for the container handling at a port. The AGV system is modelled with a time-driven approach and executed on efficient simulation engines implemented by using Cilk, a multi-threaded parallel programming language developed at MIT. The speedup results of the AGV simulation over sequential versions are documented. We also...
