PURPOSE To compare the success rates, complications, and visual outcomes between silicone Ahmed glaucoma valve (AGV) implantation with 96 mm(2) (FP8) or 184 mm(2) (FP7) surface areas. METHODS This study is a retrospective review of the records from 132 adult patients (134 eyes) that underwent silicone AGV implant surgery. Among them, the outcomes of 24 eyes from 24 patients with refractory gl...
PURPOSE To evaluate the effect of preoperative intravitreal bevacizumab (IVB) injection on the surgical outcome of Ahmed glaucoma valve (AGV) implantation according to the angle status in neovascular glaucoma (NVG) eyes. MATERIALS AND METHODS This retrospective study included 70 NVG patients who underwent AGV implantation and were followed up for at least 12 months. An IVB injection before AG...
This paper presents a multi-objective genetic algorithm (MOGA) with Pareto optimality and elitist tactics for the control system design of automated guided vehicle (AGV). The MOGA is used to identify AGV driving system model and optimize its servo control system sequentially. In system identification, the model identified by least square method is adopted as an evolution tutor who selects the i...
Purpose: In this paper a new architecture and control strategy of an AGV is proposed. It is organized as follows. The system architecture is explained in section 2. Section 3 deals with the kinematics model of the AGV path, prediction and control. Section 4 describes the experiments. The conclusion and recommendation are given in section 5. Design/methodology/approach: It is a three wheels vehi...
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...
This paper presents a colored resourceoriented Petri net (CROPN) modeling method to deal with conflict and deadlock arising in Automated Guided Vehicles (AGV) systems. The work can be viewed as the continuation of some of the authors’ previous work. Some unique features in AGV systems require the further investigation into their deadlock avoidance using CROPN models. The proposed approach can e...
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...
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...
