抽象恶意软件构成了对网络基础架构的主要威胁,该威胁容易受到几种破坏性恶意软件攻击的影响,例如病毒和勒索软件。传统的Antimalware软件可提供有限的效率,以防止恶意软件删除,因为不断发展的恶意软件能力(例如多态性)。Antimalware仅删除了其签名的恶意软件,并且对零日间攻击无效和无助,几项研究工作利用了监督和无监督的学习算法来检测和分类恶意软件,但假阳性占上风。这项研究利用机器学习来通过采用机器学习技术(包括特征选择技术以及网格搜索超参数优化)来检测和对恶意软件进行分类。主成分分析与Chi Square结合使用,以治愈维数的诅咒。支持向量机,K最近的邻居和决策树用两个数据集分别训练模型。使用混乱矩阵,精度,召回和F1评分评估了研究模型。使用CICMALMEM数据集分别使用K最近的邻居,决策树和支持向量机获得了99%,98.64%和100%的精度,该数据集分别具有相等数量的恶意软件和良性文件,K最近的邻居无法实现误报。未来的作品包括采用深度学习和集成学习作为分类器以及实施其他超参数优化技术。关键字:恶意软件检测,功能选择,超参数调整,网格搜索,机器学习。Accuracy of 97.7%,70% and 96% was achieved with K Nearest Neighbor, Decision Tree and Support Vector Machine respectively with Dataset_Malware.csv dataset, K Nearest Neighbor achieved False Positives of 38.The Model was trained separately with default hyperparameters of the chosen algorithms as well as the optimal hyperparameters obtained from Grid Search and it was discovered that optimizing超参数和与主组件分析获得的功能和Chi Square获得的功能使用具有相等数量的良性和恶意文件(CICMALMEM数据集)的数据集训练模型,从而通过支持向量机获得了最佳性能。简介的使用互联网的使用兴起,这是一个全球互连计算机网络的网络,带来了新的风险和漏洞。网络安全面临的主要问题之一是恶意攻击(Abiola&Marhusin,2018年)。恶意软件(也称为恶意软件)是侵入性软件,其设计具有伤害的特定目标,获得
从今天的角度来看,很明显,碳捕获和存储(CCS)和碳捕获和利用率(CCU)必须在气候中立的道路上发挥作用。的原因是,某些领域的排放很难或不可能减轻。在其最新报告中,IPCC还假设,与其他降低措施一起,CCS/CCU是难以抗化的排放密集型部门的必要气候技术,如果不超过1.5度的温度升高。因此,联邦政府将有可能在德国使用这些技术。The vast majority of scientific studies into greenhouse gas neutrality which were assessed for the Federal Government's last evaluation report on the Carbon Dioxide Storage Act (report of 22 December 2022, Bundestag printed paper 20/5145) arrive at the conclusion that, from as early as 2030, it will be necessary to capture and store or utilise relevant volumes of CO 2 if climate neutrality is to be achieved by 2045.这些行业尤其如此,而不仅仅是这些行业 - 由于欧洲排放交易允许的价格上涨,其排放量很难减少并且遇到成本压力的增加,例如水泥和石灰行业,例如基本化学品工业的一部分和废物燃烧。这些部门需要在气候中立的商业活动和作为德国经济的一部分的良好未来的前景。
摘要 - 当今的商业格局的特点是竞争和动态,这将人力资源管理转变为组织的基本战略合作伙伴。员工营业额会带来影响生产力和知识管理的风险。本研究的重点是使用机器学习(ML)模型来预测员工的离职。在培训过程中,使用了一个由4410个记录和29个变量组成的数据集,在培训和评估十种模型的过程中,遵循了人工智能(AI)方法。调查结果表明,XG增强分类器(XGBC)和随机森林(RF)模型达到了最佳准确性和性能率,为98.8%和98.7%。Followed by Decision Tree Classifier (DT) with 97.6%, and the other models, such as Gradient Boosting Classifier (GBC), Ada boost Classifier (AC), Logistic Regression (LR), KN Classifier (K-NNC), SGD Classifier (SGDC), Support Vector Classifier (SVC) and Nu Support Vector Classifier (NuSVC), achieved the following费率:分别为88.4%,85.4%,84%,82.2%,83.0%,83.0%,55.0%。最后,可以得出结论,模型在预测中是有用且有效的。建议在人力资源管理策略中实施实际实施,以进行主动干预。
摘要。本文基于材料科学和资源利用的基本原理和原则。原位资源利用率(ISRU)可以充分利用太空中的材料来产生人类生存甚至星际迁移计划所需的资源。Bio-based biofuel production solutions can address human consumption in space exploration while allowing the production of fuels in a sustainable manner, with minimal inputs and producing cleaner, more environmentally friendly fuels.ISRU biofuel production can be achieved by directly converting inorganic carbon (atmospheric CO2) into target compounds as biofuels by autotrophic microorganisms, or by fixing carbon and then use将生物量或复杂底物转化为靶化合物的代谢工程,完成了两步生物燃料生产过程。在本文中,我们通过ISRU调查了在火星上生产生物燃料生产的潜在微生物细胞工厂,从而导致了一些相关的突破和发现。本文通过一系列研究推进了研究内容的发展。在本文中,我们研究并优化了基于基本燃料性能研究的新能源燃料的使用。根据先前的基础研究,本文在能源研究领域提供了一种新的思维和研究方式。
日内瓦,2024年6月14日,亲爱的先生/女士,我很高兴提名您参加IPCC范围范围会议,以获取有关IPCC二氧化碳去除技术和碳捕获技术和碳的利用率和存储的报告,并由IPCC任务组持有IPCC工作组在国家绿色绿色天然气(TFI)上(TFI),并在tive extriede(Tfi)中持续了extried extrection fornection(TFI),又有23次(tfi)ever extried ection> 30场地将很快得到确认。The IPCC Working Group III (WGIII) contribution to the Sixth Assessment Report (AR6) states that “The deployment of carbon dioxide removal (CDR) to counterbalance hard-to-abate residual emissions is unavoidable if net zero CO 2 or GHG emissions are to be achieved” and provides a summary of the role for CDR technologies in future mitigation pathways (Table TS.7).2006年IPCC准备国家库存的指南提供了估算碳捕获,利用和存储活动排放的方法,但是,经过20年后,鉴于新技术和新的经验数据的出现,及时进行了审查。

REGILIENCE aims to foster the adoption and wide dissemination of regional climate resilience pathways, following a demand-driven approach and bearing in mind the expertise and knowledge acquired, as well as the solutions available from Innovation Actions (or sister projects) ARSINOE, IMPETUS, and TransformAr and other sources. It is by definition a “Coordination and Support Action” (CSA), supporting other sister projects to amplify the reach and impact of results, coordinate actions and maximise benefits for communities impacted by climate change. The objective of the sustainability and long-term exploitation strategy is to ensure that the solutions and outcomes achieved, as well as processed developed, are utilized by relevant institutions, partners and stakeholders. Given the nature of REGILIENCE project, the focus of the exploitation strategy is not to make new solutions marketable; rather, the aim is to ensure the uptake from other European regions beyond the timeframe of the project. This means ensuring that the solutions and tools developed (both within Innovation Actions regions and REGILIENCE Focus regions) can be as much as possible visible and accessible to other European regions. It also implies maintaining and strengthening synergies and collaborations between regional authorities, institutions, communities and key stakeholders in the implementation of climate-resilient development pathways.
使用指标(例如平均平均精度(MAP,标准度量测量检测准确性)在整个交叉点(IOU)阈值从50%到95%(定义了预测和地面实现框之间的重叠),精度,召回和GPU和CPU的跨越速度。The results highlight trade-offs between model complexity and performance: smaller variants like YOLOv11-n achieved faster inference speeds (170.74 FPS on GPU and 5.86 ms on GPU), while larger models like YOLOv11-x excelled in detection accuracy and recall but at the cost of slower speeds (240.03 FPS on GPU and 4.17 ms on GPU).yolov11-s提供了最高FPS(1120.46 GPU FPS)的平衡,但准确性和回忆为中等。这些发现证明了Yolov11变体对应用程序要求的适应性,从高速实时系统到优先级检测准确性的场景。这项研究通过为yolov11变体提供详细的性能基准来推进对象检测。它提供了在不同领域中部署Yolov11的实用见解,包括物流,交付跟踪和其他需要有效且准确的对象检测的域。关键字:Yolo; Yolov11;对象检测模型;深度学习计算机视觉;神经网络;
德国发布了新的气候目标,以便到2045年达到气候中立。本文展示了到2050年的德国电力电网成本最佳能源供应系统的途径。对区域性的特殊考虑,该系统基于年度近视优化,并采用了所需的能源系统转换措施和相关的系统成本。结果指出,能源存储系统(ESS)是可再生能源集成的基础,以便进行可行的能量过渡。此外,对存储技术的投资增加了太阳能和风能技术的使用。太阳能投资高度伴随着短期电池存储的安装。长期存储技术(例如H2)伴随着风力技术的高安装。结果指出,如果氢投资的成本继续大幅降低,预计氢投资将覆盖短期电池。此外,在能量系统中ESS的强烈存在,预计将完全排除生物质能量。With the current emission reduction strategy and without a strong presence of large scale ESS into the system, it is unlikely that the Paris agreement 2° C target by 2050 will be achieved, let alone the 1.5° C Keywords: Energy Market, Energy Planning, 1.5-Degree- target, Energy Storage Systems, Grid Integration, Energy System Optimization
