Applying an Ordinal Priority Approach Based Neutrosophic Fuzzy Axiomatic Design Approach to Develop Sustainable Geothermal Energy Source

Geothermal energy is considered a renewable,environmentally friendly,especially carbon-free,sustainable energy source that can solve the problem of climate change.In general,countries with geothermal energy resources are the ones going through the ring of fire.Therefore,not every country is lucky enough to own this resource.As a country with 117 active volcanoes and within the world’s ring of fire,it is a country whose geothermal resources are estimated to be about 40%of the world’s geothermal energy potential.However,the percentage used compared to the geothermal potential is too small.Therefore,this is the main energy source that Indonesia is aiming to exploit and use.However,the deployment and development of this energy source are still facing many obstacles due to many aspects from budget sources due to high capital costs,factory construction location,quality of resources,and conflicts of the local community.In this context,determining the optimal locations for geothermal energy sites(GES)is one of the most important and necessary issues.To strengthen the selection methods,this study applies a two-layer fuzzy multi-criteria decision-making method.Through the layers,the Ordinal Priority Approach(OPA)is proposed to weight the sub-criteria,the main criterion,and the sustainability factors.In layer 2,the Neutrosophic Fuzzy Axiomatic Design(NFAD)is applied to rank and evaluate potential locations for geothermal plant construction.Choosing the right geothermal energy site can bring low-cost efficiency,no greenhouse gas emissions,and quickly become the main energy source providing electricity for Indonesia.The final ranking shows Papua,Kawah Cibuni,and Moluccas as the three most suitable cities to build geothermal energy systems.Kawah Cibuni was identified as the most potential GES in Indonesia,with a score of 0.46.Papua is the second most promising GES with a score of 0.45.Next is the Moluccas,with a score of 0.39.However,the three least potential sites among the 15 studied sites are Lumut Balai,Moluccas and Patuha,with scores of 0.08,0.11 and 0.17,respectively.The conclusion of this study also classifies positions into groups to aid in decision-making.

Boundedness and liveness enforcement for labeled Petri nets using transition priority

This paper deals with the supervisory control problem of discrete event systems modeled by labeled Petri nets. The system is originally unbounded. First, the solvability of the problem is confirmed. A necessary condition is given and proven for the existence of a feasible priority-based controller based on the notions of liveness and transition invariants. Next, a cyclic behavior graph is constructed, which shows the reachable markings that guarantee the maximum liveness of the system within a given bound vector. Finally, an on-line control strategy is proposed to enforce boundedness and liveness to the given system by appending priority relations to transitions. The dynamic priority relation changes flexibly according to the current state of the system and enforces the system evolving in a bounded and live manner. In addition, numerical examples are studied to verify the validity of the proposed approach that remains the structure of the plant net and is efficient for on-line control.

Prevalence of Some World Health Organization Priority Organisms from an Abattoir at Kwata, Anambra State, Nigeria

The abattoir is one of the important sectors in the food industry, therefore the need for close monitoring of everything concerning it to minimize microbial contamination. The aim of the study is to identify bacteria listed as WHO priority organisms associated with meat from Kwata abattoir in Awka, Anambra state. The study was carried out over a three (3) months period from September to December 2022. Thirteen samples were collected from the floor, table, water, meat, knife and soil in the abattoir. The samples were cultured using streak and spread plate methods on MacConkey and Cetrimide agar. The isolates were identified with the following biochemical tests: catalase, oxidase, citrate and indole tests. Ampiclox levofloxacin, gentamicin, ofloxacin impenem ceftraixone, cefixime, cefuroxime and nitrofurantoin were used for sensitivity test following Kirby Bauer disc diffusion method and biofilm formation was determined using the tube method. The 75 isolates obtained were identified as follows;29.3% E. coli, 26.7% Klebsiella spp., 16% Proteus spp., and 28% Pseudomonas spp. The result of antibiotics sensitivity test interpreted using the European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints showed that (98%) of the isolates were resistant to the antibiotics used. Test for biofilm formation with 52 isolates showed 31 strong, 12 moderate and 9 weak biofilm formers. The result of this study confirms the presence of bacteria contaminants within the WHO priority list in the abattoir, as such there is need for improved handling of animals. Slaughtering, cleaning and distribution of meat should be done using aseptic procedures. .

Priority Detector and Classifier Techniques Based on ML for the IoMT

Emerging telemedicine trends,such as the Internet of Medical Things(IoMT),facilitate regular and efficient interactions between medical devices and computing devices.The importance of IoMT comes from the need to continuously monitor patients’health conditions in real-time during normal daily activities,which is realized with the help of various wearable devices and sensors.One major health problem is workplace stress,which can lead to cardiovascular disease or psychiatric disorders.Therefore,real-time monitoring of employees’stress in the workplace is essential.Stress levels and the source of stress could be detected early in the fog layer so that the negative consequences can be mitigated sooner.However,overwhelming the fog layer with extensive data will increase the load on fog nodes,leading to computational challenges.This study aims to reduce fog computation by proposing machine learning(ML)models with two phases.The first phase of theMLmodel assesses the priority of the situation based on the stress level.In the second phase,a classifier determines the cause of stress,which was either interruptions or time pressure while completing a task.This approach reduced the computation cost for the fog node,as only high-priority records were transferred to the fog.Low-priority records were forwarded to the cloud.Four MLapproaches were compared in terms of accuracy and prediction speed:Knearest neighbors(KNN),a support vector machine(SVM),a bagged tree(BT),and an artificial neural network(ANN).In our experiments,ANN performed best in both phases because it scored an F1 score of 99.97% and had the highest prediction speed compared with KNN,SVM,and BT.

高校“非升即走”制度下教师权益保障困境及破解路径

随着“非升即走”成为我国高等学校教师聘任的主流制度,高校教师的权益保障问题在人事制度改革和相关立法中的重要性和紧迫性日益凸显。结合理论研究和司法实践来看,我国高校教师面临的权益保障困境主要表现为“学术青椒”的尴尬:在“非升即走”聘用合同签订前,高校教师的法律身份模糊;在签订合同时,高校教师的主体性尤其是平等参与权缺失;在履行合同中,高校教师权利救济渠道不畅。这些问题的主要原因在于“学术锦标赛”的异化:高校人事管理的相关法律内容模糊、高校办学自主权边界不清和“非升即走”制度的价值偏离。破解“非升即走”制度下高校教师权益保障的现实困境的关键在于学术生态的优化:国家层面应明确“非升即走”聘用合同是“具有行政要素的劳动合同”的法律属性,重构高校教师“兼具公权与私权性质的特殊劳动者”的法律身份,完善高校教师聘任的相关法律体系;高校层面应重塑“非升即走”的制度价值,充分发挥制度的激励和促进作用,完善“非升即走”制度内容及配套措施,健全教师权益保障机制。

考虑电动汽车优先级需求的两阶段优化调度策略

随着光伏发电渗透率的升高,光伏出力的不确定性会影响电网的安全稳定运行。而利用电动汽车(EV)移动储能的特性可以实现EV和光伏的协同增效。本文基于EV能量调度的灵活性,构建了考虑用户充电需求的EV两阶段优化调度模型:在日前预调度阶段,建立光伏的就地消纳偏差最小、EV充电完成率最大、EV用户出行成本最小的多目标优化函数,并引入充放电系数对EV的充电行为进行优化;在实时调度阶段,负荷聚合商结合各时段EV的实际充电需求,根据调度优先级对优化后的充放电系数修正,保证EV充电的公平性,制定出最优的充放电策略。通过综合考虑EV用户对于充电完成度和充电成本的不同需求,对不同充电模式、不同权重系数进行分析,同时考虑了用户改变充电需求的情况,验证本文所提策略在降低光伏消纳偏差量、满足用户充电需求方面具有明显效果。

网联混合流高速公路车道管理及通行能力分析

为提高网联混合交通流环境下高速公路基本路段通行能力,需针对车流量、网联自动驾驶车辆(CAV)比例制定与之匹配的车道管理策略。针对低CAV比例环境下CAV专用车道闲置浪费的问题,提出了一种CAV优先车道管理策略。利用跟驰模型推导了混合交通流基本图模型,构建了人工驾驶车辆(HV)专用车道、CAV专用车道、混行车道及CAV优先车道通行能力模型,分析了高速公路不同车道组合方案适用的交通需求范围。然后,以双向4车道高速公路为例,基于SUMO仿真平台分析了CAV优先车道性能,对不同车道组合方案的通行能力和适用范围进行了仿真验证,并从效率、安全及能耗角度对车道组合方案进行了比较。结果表明:在适用性方面,CAV比例p≤0.5时,两条混行车道适用的交通需求范围最大,CAV优先车道次之,CAV专用车道最小;在效率方面,p≤0.5时,设置CAV专用车道方案的效率最差,CAV优先车道表现较好,且p越小优先车道效率提升越显著;在安全、能耗方面,设置CAV专用车道方案的能耗和安全性能较佳,CAV优先车道次之;在p>0.5时,设置CAV专用车道方案的综合表现更优;在多种车道管理方案均可行时,相比于两条混行车道方案,采取其他车道管理措施在安全、能耗上的表现均有提升;在需求D≤2500 veh/h,p≤0.5时,相比于其他车道方案,采用CAV优先车道方案既能满足通行需求、降低能耗,也能更充分地利用道路资源,综合表现均衡。

抢占式调度问题的PPTA模型与验证方法

优先级用于解决诸如在资源共享和安全设计等方面的冲突,已经成为实时系统设计中不可或缺的一部分.对于引入优先级的实时系统,每个任务都会被分配优先级,这就导致低优先级的任务在运行时可能会被高优先级的任务抢占资源,进而给实时系统带来抢占式调度问题.现有研究,缺乏一种可以直观表示任务的优先级以及任务之间的依赖关系的建模及自动验证方法.为此,提出抢占式优先级时间自动机(PPTA)并引入抢占式优先级时间自动机网络(PPTAN).首先,通过在时间自动机上添加变迁的优先级来表示任务的优先级,再利用变迁将具有依赖关系的任务相关联,从而可以利用PPTA建模带有优先级的实时任务.在时间自动机上添加阻塞位置,进而利用PPTAN建模优先级抢占式调度问题.其次,提出基于模型的转换方法,将抢占式优先级时间自动机映射到自动验证工具UPPAAL中.最后,通过建模多核多任务实时系统实例并与其他模型进行对比,说明所提模型不仅适用于建模优先级抢占式调度问题并可对其进行准确验证分析.
