The massive number of Internet of Things (IoT) devices connected to the Internet is continuously increasing. The operations of these devices rely on consuming huge amounts of energy. Power limitation is a major issue hindering the operation of IoT applications and services. To improve operational visibility, Low-power devices which constitute IoT networks, drive the need for sustainable sources of energy to carry out their tasks for a prolonged period of time. Moreover, the means to ensure energy sustainability and QoS must consider the stochastic nature of the energy supplies and dynamic IoT environments. Artificial Intelligence (AI) enhanced protocols and algorithms are capable of predicting and forecasting demand as well as providing leverage at different stages of energy use to supply. AI will improve the efficiency of energy infrastructure and decrease waste in distributed energy systems, ensuring their long-term viability. In this paper, we conduct a survey to explore enhanced AI-based solutions to achieve energy sustainability in IoT applications. AI is relevant through the integration of various Machine Learning (ML) and Swarm Intelligence (SI) techniques in the design of existing protocols. ML mechanisms used in the literature include variously supervised and unsupervised learning methods as well as reinforcement learning (RL) solutions. The survey constitutes a complete guideline for readers who wish to get acquainted with recent development and research advances in AI-based energy sustainability in IoT Networks. The survey also explores the different open issues and challenges.  相似文献

In India, more than 276 million children and youth were out of school for extended periods since March 2020 due to school closures in response to COVID-19. A key challenge has been how to measure the impact of responses to continuity of learning both to ensure more effective responses in the event of further disruptions, but also to help the education community conceptualize more creative and effective approaches to learning, through blended and flexible approaches. This study reflects on the findings from a UNICEF survey targeting parents and adolescents across 6 states in India, and identifies lessons learned for addressing learning inequities during future school closures. We focus on measuring three key variables – access to technology, their utilization, and perceived learning for different profiles of children. As students began learning from home, technology access rates in households were initially used to determine the estimated maximum reach of different distance learning modalities during school closures. Beyond access, we find significant variations in adolescents’ use of technology for learning purposes and their perceptions of learning, linked to the type of remote learning modality, gender, location and type of school. We discuss the implications for government strategies and policies to ensure better utilization of technologies which are available in households and to address equity gaps in learning opportunities.  相似文献

在“数字体育”背景下,运动员数据处理成为现代体育发展的关键。运动员个人数据的数据主体和数据控制者之间的权利义务分配是运动员数据处理的基础。数据主体权利的扩张和数据控制者义务的强化是《中华人民共和国民法典》和《通用数据保护条例》所遵循的基本价值导向。运动员数据处理的具体建构还应在体育领域行业化和特殊化基础上,遵循合法公平透明原则、目的限制原则、数据最小化原则、准确性原则、存储有限化原则、完整和保密原则,以此厘清运动员和数据控制者在运动员数据处理中的权利义务关系,保障运动员的数据权益。  相似文献

ABSTRACT

The Harwood Institute arrived in Youngstown, Ohio, in 1999; and today, over 18 years later, its teachings have made a profound effect upon the city. The Youngstown Public Library, through the leadership of Carlton Sears and Heidi Daniel, has wholeheartedly embraced the methods and ideology of the Harwood Institute, helping to reinvigorate and power a city working its way back to prosperity.  相似文献

摘要:运用文献资料、实地考察、逻辑分析和比较分析等研究方法,对达斡尔、鄂温克、鄂伦春族体育非物质文化遗产的相关理论及其相互关系问题进行了探讨,重点论述了其特有属性和共有属性。主要结论:概念是对象本质的外在表现和反映;本质是对象本身固有的本质属性,也是区别于其它同类事物的一种决定性因素;属性是对象体内固有的、客观存在的性质特征状态,包括对象的性质以及对象之间的关系。属性又分为特有属性和共有属性,其中特有属性来源于对象的性质,并决定着对象的本质;达斡尔、鄂温克、鄂伦春族体育非物质文化遗产的特有属性,包括健身性和公平性;共有属性包括竞争性、审美性、娱乐性、民族性、地域性、传承性和变异性。研究目的在于厘清属性及与属性相关概念之间的关系,认清和重视我国体育非物质文化遗产的文化内涵及属性特点,避免和解决在实际保护中存在的问题,为我国体育非物质文化遗产得到有效的传承与发展提供参考。  相似文献

In the light of pressing societal challenges such as climate change and resource scarcity, scholars are increasingly interested in studying policy mixes in the context of sustainability transitions. However, despite numerous conceptual advances and empirical insights, researchers still lack universal criteria or accepted heuristics for delineating policy mixes in these complex policy spaces. We address this gap by conducting an extensive review of the literature, synthesizing best practices, and developing an analytical framework that provides researchers with two archetypical methodological approaches. The top-down approach builds on the idea that the elements of a policy mix originate from an overarching strategic intent. By contrast, the bottom-up approach starts from the definition of a focal impact domain that is affected by a range of policy instruments. For each approach, we outline a systematic analytical procedure, then implement it to scrutinize how policy affects the emerging technological domain of energy storage in California. We find that each approach has particular advantages that render it useful for certain policy mix analyses. Discussing how researchers may choose between the two approaches or leverage their complementarities, we seek to provide the basis for a consistent research program building on the policy mix framework.  相似文献
