Optimization of Pulsed-field Gel Electrophoresis Procedure for Bacillus cereus

In order to develop a rapid and reliable method for B. cereus genotyping, factors influencing PFGE results, including preparation of bacterial cells embedded in agarose, lysis of embedded cells, enzymatic digestion of intact genomic DNA, and electrophoresis parameters allowing for reproducible and meaningful DNA fragment separation, were controlled.

A Particle Swarm Optimization Algorithm for a 2-D Irregular Strip Packing Problem

Two-Dimensional Irregular Strip Packing Problem is a classical cutting/packing problem. The problem is to assign, a set of 2-D irregular-shaped items to a rectangular sheet. The width of the sheet is fixed, while its length is extendable and has to be minimized. A sequence-based approach is developed and tested. The approach involves two phases;optimization phase and placement phase. The optimization phase searches for the packing sequence that would lead to an optimal (or best) solution when translated to an actual pattern through the placement phase. A Particle Swarm Optimization algorithm is applied in this optimization phase. Regarding the placement phase, a combined algorithm based on traditional placement methods is developed. Competitive results are obtained, where the best solutions are found to be better than, or at least equal to, the best known solutions for 10 out of 31 benchmark data sets. A Statistical Design of Experiments and a random generator of test problems are also used to characterize the performance of the entire algorithm.

Review: Recent Developments in the Uncertainty-Based Aero-Structural Design Optimization for Aerospace Vehicles

With the increasing demands of aircraft design,the traditional deterministic design can hardly meet the requirements of fine design optimization because uncertainties may exist throughout the whole lifecycle of the aircraft. To enhance the robustness and reliability of the aircraft design, Uncertainty Multidisciplinary Design Optimization( UM DO) has been developing for a long time. This paper presents a comprehensive reviewof UM DO methods for aerospace vehicles,including basic UM DO theory and research progress of its application in aerospace vehicle design. Firstly,the UM DO theory is preliminarily introduced,with giving the definition and classification of uncertainty as well as its sources corresponding to the aircraft design. Then following the UM DO solving process, the application in different coupled disciplines is separately discussed during the aircraft design process,specifically clarifying the UM DO methods for aerostructural optimization. Finally,the main challenges of UM DO and the future research trends are given.

Design of Vehicle Routing by Integrating Optimization and Simulated Annealing Approach

The vehicle routing problem (VRP) can be described as the problem of designing the optimal delivery or collection routes from one or several depots to a number of geographically scattered customers, subject to load constraints. The routing decision involves determining which of the demand s will be satisfied by each vehicle and what route each vehicle will follow in s erving its assigned demand in order to minimize total delivery cost. In this pap er, a methodology for the design of VRP by integrating optimization and simulate d annealing (SA) approach is presented hierarchically. To express the problem of vehicle routing, a new mathematical formulation is first conducted. The objecti ve function involves both the delivery cost and the vehicle acquisition cost wit h load constraints. A heuristic is then proposed to solve this problem by using SA procedure in conjunction with any solution procedure of travelling salesman p roblem (TSP). The initial configuration is arranged as one vehicle route ser ving one customer. The SA searching procedure is then developed to combine custo mer to any one of the vehicle routes existed in the system if the capacity and c ost are attractive. An important concept of this proposed heuristic is that it attempts to minimize total number of vehicle required in the system on the b asis of the fixed cost and the variable cost view points. In addition, this appr oach can be easily adapted to accommodate many additional problem complexities.

Research on the Operation Mechanism of Claim in Civil Procedure Law and the Applications on Court Trial Way Reform

In this paper, we conduct research on the operation mechanism of claim in civil procedure law and the applications on the court trial way reform. The ultimate goal of the rule of law lies in identifying and protecting the rights of citizens. Way to protect the rights of citizens is diverse, but the judicial relief is the most basic and important form of insurance. Everyone can “into” the court and get the impartiality of the judicial relief, is a measure of a country judicial level height and the rule of law implementation degree of important yardstick. Judicial system and judicial procedure to build and build a better, if the subject of litigation rights are not being met and the safeguard, can’t get through the door and it is the legislators and legal scholars over the many efforts are meaningless, under this basic condition, we propose the new perspective on the corresponding issues that is necessary.

个人信息保护公益诉讼制度建构路径优化——基于实体法与程序法交互方法

个人信息保护公益诉讼兼具实体法与程序法双重属性,基于实体法或程序法单一维度的制度建构将会陷入“一元观”困境。实体法与程序法交互为个人信息保护公益诉讼程序建构提供一种实体法关照。通过优化最具交互特征的三个支点:受案范围、责任形式和证明责任,不仅能够促进个人信息保护公益诉讼制度建构的二元论,也有利于推动实体法与程序法的一体化衔接,实现司法程序正义与实质正义。其一,从实体法维度,将“不特定多数人”公共利益说作为基础,增加“规模性”与“无差别性”的标准,解决受案范围“众多个人权益”的程序判断难题。其二,从程序法维度,通过诉讼信托的方式,允许原告受让惩罚性赔偿请求权,解决惩罚性赔偿这一责任形式缺乏实体适用空间难题。其三,从交互维度,一方面承认法官裁量分配证明责任,解决“规范说”在新型复杂案件的实体失范难题;另一方面设定证明责任减轻的请求权基础,解决裁判失度的程序适用难题。

高比例光伏接入的配电网分布式运行优化技术

高渗透率光伏和储能并网的现代配电网具有规模庞大、设备众多、运行工况复杂多变的特点,传统的集中式优化方法不再适用。与此同时,有载调压变压器、并联电容器等均为传统离散设备,导致配电网有功无功功率协调优化模型呈现非凸特性,而当前通用分布式算法仅适用于求解凸模型。为解决该问题,提出了计及模型非凸特性的配电网分布式有功无功功率协调优化方法。以提高配电网运行经济性为目标,利用随机规划理论进行光伏有功功率不确定性刻画,建立配电网分布式随机有功无功功率协调优化模型。针对所建模型的非凸特性提出基于交替寻优过程的分布式算法,实现该模型可靠求解。最后通过PG&E69节点系统进行算例分析,验证了所提分布式有功无功功率协调优化方法的有效性以及分布式算法的可靠性。

民事终结本次执行程序的制度嬗变与程序完善

民事终结本次执行程序源于法院执行实践,是法院为无可供执行财产或财产无法强制执行案件设置的一种暂时性退出机制,该制度形成之初强调“清理积案”的工具功能而忽视了自身的系统性构建,以2015年施行《中华人民共和国民事诉讼法》解释为分界点,该制度在经历了碎片化、内部体系化、外部体系化的阶段后,逐渐演化为重要的执行监管手段。2022年《中华人民共和国民事强制执行法(草案)》中进一步明晰了其适用条件和效力,但该制度仍面临着财产查明倚重职权调查、财产报告“违法过剩”引起制度空转、穷尽财产调查措施、可供执行财产认定标准有待明确、异化为“准结案”等现实问题。基于实务中存在的问题,文章明确制度设计理念、科学设定法院与执行当事人间的权利义务分工,提出终结本次执行程序的优化设想,以期提高司法执行的工作质效。

我国国家机构组织法的体系优化

国家机构组织法的立法模式有综合法模式、专门法模式和“基本法+单行法”这三种理想类型。我国各大国家机构组织法在制定之初选择的立法模式并不统一,这意味着各大国家机构组织法与其行为法、程序法、人员法的关系存在显著差异。改革开放四十多年来,各大国家机关的组织形态、职权范围及其相互关系均发生了相当大的变化,但组织法的修改却带着强大的立法惯性,未能随着各部专门法的制定而与时俱进,导致各大国家机构组织法与其行为法、程序法、人员法之间存在不少重复、错位乃至冲突。未来组织法和相关法律的修改,有必要强化国家机构组织法的体系化,统筹各大国家机构组织法与相关法律的关系,从组织法的功能定位、体例结构和具体内容三个层面对我国各大国家机构组织法体系进行整体优化。

应急响应程序时效性评估方法研究

突发事件应急响应效果评估是提高应急响应能力和水平的重要手段。由于突发事件的突发性、机理复杂、信息不完全以及应对具有时间窗口等,多指标综合评估和仿真方法一般难以满足实际的评估需求。为此,采用构造时效性评估函数的方法,既能在不完全信息下借助专家经验进行评估,又能反映应急响应程序中一环扣一环的影响关系。基于前期研究,本研究构造了一种新型的时效性评估函数,构造算例验证了函数的有效性,且使得函数最优性质的分析更简便,为应急准备、应急响应相关决策问题提供理论依据。

某矿巷道支护工序优化

为解决某矿围岩破碎、巷道锚网支护设施损坏严重、返修频率高等问题,应用爆破振动和围岩与支护相互作用机理分析了支护失效的原因,提出了“掘到哪儿,支到哪儿,喷到哪儿”的喷锚网优化支护工序。即新掘进的巷道及时清理浮石以后,首先采用素喷一层厚度50~100 mm的混凝土,然后进行钢网和锚杆支护,最后再喷一层厚度50~100 mm的混凝土。经过可行性分析和现场工业试验,证明可在不改变原支护工艺和支护材料的基础上,通过调整和优化施工顺序,可以提高支护效果,维护巷道围岩稳定,比现行支护工序节约86142.71元,研究成果可供同类矿山参考借鉴。
