Hidden systems : water, electricity, the internet, and the secrets behind the systems we use every day
\"What was the first message sent over the internet? How much water does a single person use every day? How was the electric light invented? For every utility people use each day, there's a hidden history below the surface - a story of intrigue, drama, humor, and inequity. This graphic novel provides a guided tour through the science of the past - and how the decisions people made while inventing and constructing early technology still affect the way people use it today. Full of art, maps, and diagrams, Hidden Systems is a thoughtful, humorous exploration of the history of science, and what needs to be done now to change the future.\"-- Provided by publisher.

Infrastructure and employment creation in the middle east and north africa
This study assesses the potential for job creation through infrastructure investment in the Middle East and North Africa. The region has experience in making the most of infrastructure investments, but maintaining and spreading the momentum in infrastructure will be important to support future growth and job creation. To do so, policymakers will have to recognize that there are large differences in initial conditions across the region in terms of starting stock, needs, fiscal commitments, private sector participation and job creation potential. Overall, the regions infrastructure needs through 2020 are quite large and estimated at about 106 billion dollars per year or 6.9 percent of the annual regional GDP. The differences in infrastructure and maintenance needs across sub-regions are also impressive, with developing oil exporters expected to require almost 11 percent of their GDP annually, while the oil importing countries and the GCC oil exporters expected to need approximately 6 and 5 percent of their GDP, respectively. Investment and rehabilitation needs are likely to be especially high in the electricity and transport sectors, particularly roads. Rehabilitation needs are expected to account for slightly more than half of total infrastructure needs. While oil exporters will be able to meet their national infrastructure needs if they maintain investment spending at rates prevailing in the 2000s, oil importers will fall short. The infrastructure sector has the potential to contribute to employment creation in MENA. The region could generate 2.0 million direct jobs and 2.5 million direct, indirect and induced infrastructure-related jobs just by meeting estimated, annual investment needs. However, the potential varies greatly across countries, and infrastructure alone will not resolve MENAs unemployment problem. Going forward, decisions on what
types of public spending to expand and what to downsize in order to achieve balanced budgets will have important implications for jobs. In designing country specific solutions, governments will have to tackle predictable challenges: the governance of job creation, the proper targeting and fiscal costs assessment of subsidies needed to create jobs, the design and fiscal costs of the (re)training programs needed and the expectations on the job creation effects of infrastructure.

Africa's power infrastructure : investment, integration, efficiency
This study is a product of the Africa Infrastructure Country Diagnostic (AICD), a project designed to expand the world's knowledge of physical infrastructure in Africa. The AICD provides a baseline against which future improvements in infrastructure services can be measured, making it possible to monitor the results achieved from donor support. It also offers a more solid empirical foundation for prioritizing investments and designing policy reforms in the infrastructure sectors in Africa. The book draws upon a number of background papers that were prepared by World Bank staff and consultants, under the auspices of the AICD. The main findings were synthesized in a flagship report titled Africa's infrastructure: A time for transformation, published in November 2009. Meant for policy makers, that report necessarily focused on the high-level conclusions. It attracted widespread media coverage feeding directly into discussions at the 2009 African union commission heads of state summit on infrastructure.

The construction of Bert fusion model of speech recognition and sensing for South China electricity charge service scenario
Electric charge service and management is an important part of electric power work. The effective recovery of the electric charge relates to the smooth development of daily work and continuous improvement of the operation and management of power supply enterprises. With the large-scale implementation of the card prepayment system, the problem of electricity customers defaulting on electricity charges has been solved to a large extent, but some large electricity users still fail to pay electricity charges on time. Therefore, under the current situation of power grid development, it is still necessary to strengthen the service and management of electricity charges to promote efficient recovery of electricity charges. Speech recognition technology has increasingly become the focus of research institutions at home and abroad. People are committed to enabling machines to understand human speech instructions and hope to control the machine through speech. The research and development of speech recognition will greatly facilitate people's lives shortly. The development of 5G technology and the proposal of 6G technology make the interconnection of all things not only a hope but also a reality. To realize the interconnection of all things, one of the key technical breakthroughs is the development of a new human–computer interaction sensing system. Under the guidance of relevant theories and methods, this paper systematically analyzes the user structure, electricity charge recovery management and service system, existing problems and causes in South China, and clarifies the necessity of design and application of electricity charge service system in South China power supply companies. The experimental data and empirical analysis results show that the optimized Bert fusion model can provide more digital support for the power supply companies in South China in terms of electricity charge recovery efficiency, management level system improvement, and electricity charge service.

Credibility Theory-Based Information Gap Decision Theory to Improve Robustness of Electricity Trading under Uncertainties
In the backdrop of the ongoing reforms within the electricity market and the escalating integration of renewable energy sources, power service providers encounter substantial trading risks stemming from the inherent uncertainties surrounding market prices and load demands. This paper endeavors to address these challenges by proposing a credibility theory-based information gap decision theory (CTbIGDT) to improve robustness of electricity trading under uncertainties. To begin, we establish credibility theory as a foundational risk assessment methodology for uncertain price and load, incorporating both necessity and randomness measures. Subsequently, we advance the concept by developing the CTbIGDT optimization model, grounded in the consideration of expected costs, with the primary aim of fortifying the robustness of electricity trading practices. The ensuing model is then transformed into an equivalent form and solved using established standard optimization techniques. To validate the efficacy and robustness of our proposed methodology, a case study is conducted utilizing a modified IEEE 33-node distribution network system. The results of this study serve to underscore the viability and potency of the CTbIGDT model in enhancing the effectiveness of electricity trading strategies in an uncertain environment.

Urban Energy Policies and the Governance of Multilevel Issues in Cape Town
The multiscalar challenges associated with urban energy policies are the cause of extensive interaction among multiple levels of government and social forces. However, these multilevel systems of action tend to reflect complex and unstable power and resistance patterns rather than stable co-operation processes. Thus, in this paper, a multilevel governance perspective is used as a starting point for understanding where and how multilevel interactions arise in an energy system as well as which issues are creating political conflict and the related consequences for the governance of urban energy policies. This approach is illustrated through a case study of Cape Town, which exemplifies a situation of conflicting policy and agendas at different levels of government, thus creating a great dispersion of initiatives across different scales. Integrating these initiatives within a broader coherent framework, however, is not only a technical matter. As urban energy policies deal with multilevel issues, they imply negotiating dynamic and complex compromises between different types of organisations and authorities while shaping their governance is also a matter of politics.

Infrastructure in Latin America and the Caribbean : recent developments and key challenges
This book reviews Latin America's experience with infrastructure reform over the last fifteen years. It argues that the region's infrastructure has suffered from public retrenchment and unrealistic expectations about private involvement. Poor infrastructure now hampers productivity, growth, and poverty reduction. Addressing this requires more and better spending, and acceptance that governments remain central to infrastructure provision and supervision, although the private sector still has an important role to play.

Power for all
India has led the developing world in addressing rural energy problems. By late 2012, the national electricity grid had reached 92 percent of India s rural villages, about 880 million people. In more remote areas and those with geographically difficult terrain, where grid extension is not economically viable, off-grid solutions using renewable-energy sources for electricity generation and distribution have been promoted. The positive results of the country s rural energy policies and institutions have contributed greatly to reducing the number of people globally who remain without electricity access. Yet, owing mainly to its large population, India has by far the world s largest number of households without electricity. More than one-quarter of its population or about 311 million people, the vast majority of whom live in poorer rural areas, still lack an electricity connection; less than half of all households in the poorest income group have electricity. Among households with electricity service, hundreds of millions lack reliable power supply.

Real option valuation of a decremental regulation service provided by electricity storage
This paper is a quantitative study of a reserve contract for real-time balancing of a power system. Under this contract, the owner of a storage device, such as a battery, helps smooth fluctuations in electricity demand and supply by using the device to increase electricity consumption. The battery owner must be able to provide immediate physical cover, and should therefore have sufficient storage available in the battery before entering the contract. Accordingly, the following problem can be formulated for the battery owner: determine the optimal time to enter the contract and, if necessary, the optimal time to discharge electricity before entering the contract. This problem is formulated as one of optimal stopping, and is solved explicitly in terms of the model parameters and instantaneous values of the power system imbalance. The optimal operational strategies thus obtained ensure that the battery owner has positive expected economic profit from the contract. Furthermore, they provide explicit conditions under which the optimal discharge time is consistent with the overall objective of power system balancing. This paper also carries out a preliminary investigation of the ‘lifetime value’ aggregated from an infinite sequence of these balancing reserve contracts. This lifetime value, which can be viewed as a single project valuation of the battery, is shown to be positive and bounded. Therefore, in the long run such reserve contracts can be beneficial to commercial operators of electricity storage, while reducing some of the financial and operational risks in power system balancing.

Remittances and development : lessons from Latin America
Workers' remittances have become a major source of financing for developing countries and are especially important in Latin America and the Caribbean, which is at the top of the ranking of remittance receiving regions in the world. While there has been a recent surge in analytical work on the topic, this book is motivated by the large heterogeneity in migration and remittance patterns across countries and regions, and by the fact that existing evidence for Latin America and the Caribbean is restricted to only a few countries, such as Mexico and El Salvador. Because the nature of the phenomenon varies across countries, its development impact and policy implications are also likely to differ in ways that are still largely unknown. This book helps fill the gap by exploring, in the specific context of Latin America and Caribbean countries, some of the main questions faced by policymakers when trying to respond to increasing remittances flows. The book relies on cross-country panel data and household surveys for 11 Latin American countries to explore the development impact of remittance flows along several dimensions: growth, poverty, inequality, schooling, health, labor supply, financial development, and real exchange rates.
