Production Of Hydrogen

Achieving the CO2 reduction targets for 2050 requires extensive measures being undertaken in all sectors. In contrast to energy generation, the transport sector has not yet been able to achieve a substantive reduction in CO2 emissions. Measures for the ever more pressing reduction in CO2 emissions from transportation include the increased use of electric vehicles powered by batteries or fuel cells. The use of fuel cells requires the production of hydrogen and the establishment of a corresponding hydrogen production system and associated infrastructure. Synthetic fuels made using carbon dioxide and sustainably-produced hydrogen can be used in the existing infrastructure and will reach the extant vehicle fleet in the medium term. All three options require a major expansion of the generation capacities for renewable electricity. Moreover, various options for road freight transport with light duty vehicles (LDVs) and heavy duty vehicles (HDVs) are analyzed and compared. In addition to efficiency throughout the entire value chain, well-to-wheel efficiency and also other aspects play an important role in this comparison. These include: (a) the possibility of large-scale energy storage in the sense of so-called ‘sector coupling’, which is offered only by hydrogen and synthetic energy sources; (b) the use of the existing fueling station infrastructure and the applicability of the new technology on the existing fleet; (c) fulfilling the power and range requirements of the long-distance road transport.

4G Cellular Networks

The currently widely used 4G cellular networks face many challenges. The growing demand for high-resolution mobile multimedia applications is bringing these networks to their practical limits. 5G networks, the next generation of wireless communications, are standardized to ease the burden on current infrastructure by offering significantly higher data rates through increased channel bandwidth. Given the lack of accessible frequencies traditionally used for mobile communications, millimeter bandwidths (mmWave) are quite a challenging alternative. This technology is a cornerstone of upcoming 5G networks, allowing faster data speeds and much higher bandwidth than ever before, but not every 5G network will necessarily use this frequency band, at least not all the time. As with any new technology, there are unavoidable problems that need to be overcome. The purpose of the research and analysis in this article is to systematize issues and solutions related to the potential problems of spectrum sharing in mmWave frequency range, its suitability for long-distance communications, indoors, in bad weather conditions, as well as biological aspects, and relevant conclusions have been done to meet these challenges.

Almost All

In Canada, a country of vast landscapes, northern climates and relatively few people, the formal provision of education has always involved alternatives. Records going back to the late 1800s discuss pilot projects that provided education to school-aged children in remote rural areas. Correspondence education, beginning in 1919 and offered by almost all provincial authorities, depended on the post and long-distance haulage to link students and teachers (Haughey, 1990). Each new technology became a part of an educational provision that was of particular importance to secondary school students, who were unable to obtain sufficient courses at their local school to qualify for a high school diploma. More recently, the advent of computers and the Internet have transformed this alternative form of education. It has changed from one for those unable to attend classroom-based instruction to one that is being chosen by students for its adaptability and flexibility, as well as for the ongoing reasons associated with long distances to schools, unavailable courses, and family and personal circumstances. In this chapter, I review the development and present configurations of online schooling in Canada and discuss trends and issues this new form of provision has raised.

Technical Reasoning

Explaining the Future addresses the questions “will this new technology solve the problem that its inventors claim it will,” “will it succeed for any application at all,” “can we narrow down the options before we spend a lot of money on development,” and “how do we persuade colleagues, investors, clients, or readers of our technical reasoning?” Whether the person answering these questions is a researcher, a consultant, a venture capitalist, or a CTO, they will need to be able to answer them clearly and systematically. Most learn these skills only through years of experience. However, by making them explicit, this book makes the learning process more efficient and speeds its readers toward higher-level careers. First, it will provide the tools to think through matching new (and old) technologies, materials, and processes with applications: it covers the questions to ask, the resources needed to answer them, and who deserves trust. Then, it discusses analyzing the information that has been gathered in a systematic way and dealing with uncertainty. Next, there are chapters on communication, including tailoring documents to a specific audience, making a persuasive and structured technical argument, and writing an explanation that is credible and easy to follow. Finally, the book includes a case study: a real worked example that goes from an idea through the twists and turns of the research and analysis process to a final report.
