Apply the Double-Weight Neural Network to Dynamic Power Management

This paper expounds a data-fitting algorithm for the double-weight neural network,and presents a new algorithm for the system's power management on the base of that.The double-weight neural network learns knowledge from the past idle periods of the system,and predicts the lengths of the coming idle periods.As a result of that,the system can switch its running states and re- duce the power dissipation according to the predictive values.The results of the experiments prove that this algorithm shows a better performance in increasing the right rate of shutting down and reducing the power consumption than other traditional ones.

A review of closed-loop reservoir management

The closed-loop reservoir management technique enables a dynamic and real-time optimal production schedule under the existing reservoir conditions to be achieved by adjusting the injection and production strategies. This is one of the most effective ways to exploit limited oil reserves more economically and efficiently. There are two steps in closed-loop reservoir management： automatic history matching and reservoir production opti- mization. Both of the steps are large-scale complicated optimization problems. This paper gives a general review of the two basic techniques in closed-loop reservoir man- agement; summarizes the applications of gradient-based algorithms, gradient-free algorithms, and artificial intelligence algorithms; analyzes the characteristics and application conditions of these optimization methods; and finally discusses the emphases and directions of future research on both automatic history matching and reservoir production optimization.

Improving the Performance of Urban Waste Management Systems in the Context of a Closed-Loop Supply Chain

The saving of non-renewable energies, as well as the reduction of emissions into the environment, are two crucial objectives of industrial production. The recovery of post-consumer products associated with the use of end-of-life products is part of a context of optimization of these objectives. This recovery maximizes the use of resources from end-of-life products in a circular logic while recording the environmental footprint. This study considers a recycling strategy adapted to the need and urgency to reduce greenhouse gas emissions caused by global warming. The proposed model aims to optimize the profits of the circular manufacturing strategies while minimizing operational costs (collection, sorting, recycling), transport, GHG emissions and recycling. In this paper, a compromise between the gains of CM and the costs associated with it was studied. The robustness of the designed model was tested using a case study based on real-world scenarios. A sensitivity analysis was carried out to study the impact of the emission cost on the overall objective, considering the two options currently offered to industries. The obtained results support companies to take the ecological aspect into account and integrate sustainable development into their strategic axes for their logistics supply chains.

Application of improved PSO to power transmission congestion management optimization model

The parameters of particles were encoded firstly, then the constraint conditions and fitness degree were processed, and the calculation steps of the improved PSO algorithm were presented. Finally, the issues with the adoption of the improved PSO algorithm were solved and the results were analyzed. The results show that it is beneficial to obtaining the optimal solution by increasing the number of particles but that will also increase the operation time. On the aspects of solving continuous differentiable non-linear optimization model with equality and inequality constraints, the optimization result of PSO algorithm is the same as that of the interior point method. Compared with genetic algorithms (GA), PSO algorithm is more effective in the local optimization, and unlike GA, it will not be early maturity. Meanwhile, PSO algorithm is also more effective in the boundary optimization than genetic algorithm.

Double-balloon endoscopic retrograde cholangiopancreatography for patients who underwent liver operation: A retrospective study

BACKGROUND Double-balloon endoscopic retrograde cholangiography (DB-ERC) is widely performed for biliary diseases after reconstruction in gastrointestinal surgery,but there are few reports on DB-ERC after hepatectomy or living donor liver transplantation (LDLT).AIM To examine the success rates and safety of DB-ERC after hepatectomy or LDLT METHODS The study was performed retrospectively in 26 patients (45 procedures) who underwent hepatectomy or LDLT (liver operation:LO group) and 40 control patients (59 procedures) who underwent pancreatoduodenectomy (control group).The technical success (endoscope reaching the choledochojejunostomy site),diagnostic success (performance of cholangiography),therapeutic success(completed interventions) and overall success rates,insertion and procedure(completion of DB-ERC) time,and adverse events were compared between these groups.RESULTS There were no significant differences between LO and control groups in the technical [93.3%(42/45) vs 96.6%(57/59),P=0.439],diagnostic [83.3%(35/42) vs83.6%(46/55),P=0.968],therapeutic [97.0%(32/33) vs 97.7%(43/44),P=0.836],and overall [75.6%(34/45) vs 79.7%(47/59),P=0.617] success rates.The median insertion time (22 vs 14 min,P <0.001) and procedure time (43.5 vs 30 min,P=0.033) were significantly longer in the LO group.The incidence of adverse events showed no significant difference [11.1%(5/45) vs 6.8%(4/59),P=0.670].CONCLUSION DB-ERC after liver operation is safe and useful but longer time is required,so should be performed with particular care.

Intelligent Information Management in Aquaponics to Increase Mutual Benefits

Aquaponics are feedback and two player systems, in which fish and crops mutually benefit from one another and, therefore require close monitoring, management and control. Vast amount of data and information flow from the aquaponics plant itself with its huge amount of smart sensors for water quality, fish and plant growth, system state etc. and from the stakeholder, e.g., farmers, retailers and end consumers. The intelligent management of aquaponics is only possible if this data and information are managed and used in an intelligent way. Therefore, the main focus of this paper is to introduce an intelligent information management (IIM) for aquaponics. It will be shown how the information can be used to create services such as predictive analytics, system optimization and anomaly detection to improve the aquaponics system. The results show that the system enabled full traceability and transparency in the aquaponics processes (customers can follow what is going on at the farm), reduced water and energy use and increased revenue through early fault detection. In this, paper the information management approach will be introduced and the key benefits of the digitized aquaponics system will be given.

基于动态优化周期的风光氢储耦合系统改进能量管理策略

电/氢混合储能对离网风光发电系统的功率调节能力起到不可忽视的作用,但未充分考虑能量管理的综合性能。针对上述问题,提出了一种基于动态优化周期的改进能量管理策略。首先,以系统运行成本最小为目标进行日前优化。然后,在日内滚动优化的过程中自适应调节权重因子,合理协调短期功率平抑和长期状态优化,并对滚动优化周期进行动态调节,在减少冗余调节的同时,提升控制器的实时响应能力。最后,在实时校正层分别使用逐次变分模态分解和双层模糊控制对混合储能功率进行初次分配和二次分配,充分利用混合储能的运行特性并提升系统鲁棒性。算例分析表明,与传统策略相比,改进能量管理策略可使系统运行成本、能量失衡率和计算时间分别降低38.3%、63.1%和57.9%,提高了系统能量管理的经济性、可靠性和实时性。
