We report four cases in which a pericardium (Tutoplast) plug was used to repair a corneoscleral fistula after Ahmed Glaucoma Valve (AGV) explantation. In four cases in which the AGV tube had been exposed, AGV explantation was performed using a pericardium (Tutoplast) plug to seal the defect previously occupied by the tube. After debridement of the fistula, a piece of processed pericardium (Tuto...

This paper presents a flexible framework to simulate transport systems based on automated guided vehicles (AGVs). The used perform the simulation also serves implement different policies and algorithms in global control system. For all mobile platforms, regardless of their application, there is great interest having model environment. However, tend be complex, with many needing execute tasks at...

Automated guided vehicles (AGVs) form a large and important part of the logistics transportation systems in today's industry are widely used. One main problems control AGV is routing problem, where all robots attempt to execute their allocated tasks without congestions with other robots. This complex problem variety solutions exist literature this purpose. possible solution that not investigate...

This paper investigates an improved genetic algorithm on multiple automated guided vehicle (multi-AGV) path planning. The innovations embody in two aspects. First, three-exchange crossover heuristic operators are used to produce more optimal offsprings for getting more information than with the traditional two-exchange crossover heuristic operators in the improved genetic algorithm. Second, dou...

The Automated Guided Vehicles (or AGVs for short) have become an important option in the container handling process. We present a parallel simulation system for the study of AGV routing schemes. We model the AGV system based on a time-driven approach and execute the model on an efficient simulation engine implemented by using Cilk, a parallel programming language developed at MIT. We will elabo...

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...

In the era of Industry 4.0, as main force intelligent logistics systems, multi-Automated Guided Vehicle (AGV) systems have developed rapidly. At present, multi-AGV are a research hotspot, where task allocation key technology is being paid much attention. this study, new scheme for proposed based on distributed framework. The AGVs can autonomously select tasks, plan paths, and communicate with i...
