The document outlines the basic elements of short fiction stories, including characters, setting, plot, conflict, point of view, and theme. It defines these elements and provides examples. Characters can be major or minor, round or flat. The setting establishes the location and time period. The plot involves events building to a climax and resolution. Conflict can be external or internal. Point of view determines who tells the story. The theme conveys a central message or insight.
GM is pursuing an electrification strategy to reduce dependence on petroleum by developing a portfolio of advanced propulsion technologies including hybrids, plug-in hybrids, extended range electric vehicles, and fuel cell EVs. A key part of the strategy is the Chevrolet Volt, an extended range electric vehicle that can drive up to 80 km on battery only but has a gas engine range extender for an overall driving range of up to 490 km. Significant technological advancements are still needed to improve electric drive systems, batteries, power electronics, and controls to make electric vehicles more affordable and appealing to mass market buyers.
This document provides analysis questions for three poems: "There Will Come Soft Rains" by Sara Teasdale, "Meeting at Night" by Robert Browning, and "The Sound of Night" by Maxine Kumin. It asks the reader to identify examples of literary devices like alliteration in the poems and to analyze how each portrays nature and humanity's relationship to nature. It prompts comparing the poems' descriptions of nighttime settings to accompanying paintings. Finally, it asks the reader to choose a poem and analyze the view of nature represented through examples from the text.

E-mobility | Part 4 - EV charging and the next frontier (Chinese)Vertex Holdings
For the mass adoption of electric vehicle (EV) to become a reality, EV charging infrastructure must be made accessible, quick and reliable. Current signs indicate the sector is moving in the right direction – with China, Europe, US and Japan accelerating their charging infrastructure rollout plans, and notable charging network operators (i.e. ChargePoint, EVgo and Tritium) making billion-dollar exits.

1) The document discusses electric vehicles and their potential impact on energy grids. It addresses concerns that charging electric vehicles could overload grids but argues this is not the case if charging is properly managed.
2) Charging electric vehicles can be managed at multiple levels from individual charging stations to the overall grid level to avoid peak demand times and make use of excess renewable energy production.
3) With management of electric vehicle charging, the grids will be able to support electric vehicles and the vehicles will provide benefits to the grid by enabling demand response and storing energy to help integrate more renewable resources.

The document discusses the outlook and policy actions needed for electric vehicles. It argues that electric vehicles are more sustainable than gasoline vehicles, using 30% less primary energy and emitting 25% less carbon dioxide. However, for electric vehicles to spread, governments need to provide initial incentives like preferential parking and lanes, as well as building out charging infrastructure, especially for home charging. With the right policies, electric vehicle sales are predicted to increase as costs fall with higher production volumes and rising gasoline prices.
The document discusses research on hydrogen enriched natural gas (HCNG) internal combustion engines. It provides background on using HCNG as a fuel, including that adding hydrogen to natural gas can increase combustion speed and efficiency while reducing emissions. It then outlines Tsinghua University's research activities on HCNG engines, including testing systems, control strategies, and matching engines with oxidation catalysts to reduce emissions.
1) Key factors that influence lithium battery cost-effectiveness include the purchase cost per kWh, ownership costs related to cycle life and warranty, and end-of-life disposal costs.
2) Maximizing the usable energy of a battery pack is important for optimizing costs, as it allows manufacturers to increase energy capacity while maintaining or lowering the purchase cost per kWh.
3) Reliability features, proven components, standardized modular designs, and local sourcing can help reduce the ownership costs associated with battery packs over their lifetime.
The document discusses the global outlook and development of electric vehicles and their infrastructure. It covers technical roadmaps and challenges of EVs, as well as power batteries and smart grid infrastructure. The professor argues that EVs represent a disruptive industry that requires coordinated development between governments, automakers, and suppliers to establish new industrial alliances and supply chains. EVs will play a key role in achieving global sustainable development goals.
