In this paper, we study the design and control of automated guided vehicle (AGV) systems, with the focus on the quayside container transport in an automated container terminal. We first set up an event-driven model for an AGV system in the zone control framework. Then a number of layouts of the road network (guide-path) are carefully designed for the workspace of the AGVs in a container termina...
Cardiac regenerative therapies utilizing human induced pluripotent stem cells (hiPSCs) are hampered by ineffective large-scale culture. hiPSCs were cultured in multilayer culture plates (CPs) with active gas ventilation (AGV), resulting in stable proliferation and pluripotency. Seeding of 1 × 106 hiPSCs per layer yielded 7.2 × 108 hiPSCs in 4-layer CPs and 1.7 × 109 hiPSCs in 10-layer CPs with ...
Automatic Guided Vehicles (AGVs) are unmanned vehicles that can transport loads in a warehouse. AGVs are instructed by on-board AGV control software. As multiple AGVs operate in a decentralized manner in the warehouse environment, conflicts may arise. Consequently, it is crucial to test thoroughly whether the AGV control software actually handles the potential conflicts in the appropriate way. ...
BACKGROUND To describe, a yet non-documented complication of GDI surgery (glaucoma drainage incision surgery)--anterior to posterior segment migration of Ahmed Glaucoma Valve (AGV) tube. CASE PRESENTATION We report a young 9 year old boy, diagnosed with refractory glaucoma with Reiger anomaly. History included of poor vision in both eyes, left more than right with glare since childhood. He un...
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. ...
In a competitive business environment, producing goods on time plays a very important role. In addition to regular control complexities in manufacturing environments, some unforeseen technical problems may affect the efficiency of production. The breakdown of automated guided vehicles (AGV) during manufacturing is one of these problems. This problem generally requires an instantaneous solution ...
PURPOSE To report the short-term efficacy and safety of the transfer of an Ahmed(™) glaucoma valve (AGV™) tube from the vitreous into the anterior chamber, in a patient with neovascular glaucoma who had undergone pars plana AGV(™) implantation and ultimately needed a silicone oil tamponade. CASE A 41-year-old male with proliferative diabetic retinopathy in both eyes was referred to us for tre...
This contribution presents a novel approach to address the scheduling of resource-constrained flexible manufacturing systems (FMSs). It deals with several critical features that are present in many FMS environments in an integrated way. The proposal consists in a constraint programming (CP) formulation that simultaneously takes into account the following sub-problems: (i) machine loading, (ii) ...
دراین تحقیق ابتدا یک مدل ریاضی جدید (modm) 1 برای برنامه ریزی همزمان agv 2ها و ماشین آلات پیشنهاد می گردد که این مدل جدید دارای سه تابع هدف از نوع کمینه سازی است . این اهداف عبارت اند ازحداقل سازی گستره زمانی تولید و زمان حرکت agv ها ، کمینه سازی انحراف معیار متغییرهای تعداد دفعات استفاده از هر کدام از ماشین آلات و حداقل سازی انحراف معیار متغییر تعداد دفعات حرکت مستقیم agv ها بین دو ماشین مفروض...
An excellent navigation, guidance, and control (NGC) system had a high impact on trajectory tracking the following scenarios. Both scenarios will include heading, tangent, velocity parameters in computation. However, design problem is not new issue unmanned surface vehicle (USV) autonomous ground vehivle (AGV) due to this constraint faced by many researchers since early these autonomy developme...
