A Sustainable Urban Mobility Plan (SUMP) is a strategic plan that aims to develop sustainable transport systems in urban areas. It outlines measures to enhance mobility while minimizing the impact on the environment and improving quality of life for residents. Here are key components and objectives of a SUMP: 1. **Comprehensive Approach**: SUMPs take a holistic view of urban transport, integrating various modes of mobility (public transport, cycling, walking, car-sharing, etc.) and considering the interconnections between them.
A graphometer is an instrument used for measuring and laying out angles, primarily in surveying and construction. It typically consists of a circular protractor that allows for the precise measurement of angles, often combined with a sighting mechanism for taking bearings and aligning features accurately. Graphometers can be used to determine horizontal and vertical angles, making them useful in various applications such as land surveying, architecture, and engineering projects.
An inclinometer, also known as a tilt sensor or tilt meter, is a device used to measure the angle of tilt or inclination of an object relative to a reference plane, typically the vertical or horizontal plane. Inclinometers can be used in various applications across multiple fields, including: 1. **Geotechnical Engineering**: To monitor the stability of slopes, embankments, and structures, ensuring they do not tilt dangerously or shift in position.
Molecular symmetry refers to the spatial arrangement of atoms in a molecule and how that arrangement can exhibit symmetrical properties. It is a key concept in chemistry that helps in understanding the physical and chemical properties of molecules, including their reactivity, polarity, and interaction with light (such as in spectroscopy).
The First-Hitting-Time Model is a concept used in various fields, including probability theory, stochastic processes, and queuing theory, to describe the time taken for a stochastic process to reach a specified state for the first time. This model is particularly useful in analyzing systems where events occur randomly over time. ### Key Concepts: 1. **Stochastic Processes**: A stochastic process is a collection of random variables representing a process that evolves over time.
Hypertabastic survival models refer to a class of statistical models used to analyze time-to-event data, particularly when the data exhibits complex behavior that cannot be adequately captured by traditional survival analysis models like the Cox proportional hazards model or exponential survival models. The term "hypertabastic" itself is not widely recognized in mainstream statistical literature, so it may be a specialized or newer term that has emerged in specific research contexts.
The Kaniadakis Weibull distribution is a generalized form of the Weibull distribution that is derived from the Kaniadakis formulation, which is designed to accommodate certain statistical properties particularly relevant in non-extensive statistical mechanics and complex systems. In general, the classic Weibull distribution is characterized by its shape and scale parameters and is commonly used to model reliability data and life data analysis.
Reliability theory of aging and longevity is a conceptual framework that applies principles from engineering reliability analysis to the biological processes of aging and lifespan. This approach treats the human body (and other living organisms) as a complex system composed of many components that can fail over time. It draws on the idea that just as machines have a certain probability of failure based on their design, materials, and use, biological organisms also exhibit rates of decline and failure over their lifetime.
Statistical assembly refers to a theoretical framework in statistical mechanics that deals with systems composed of a large number of particles, which can be described in terms of probabilistic distributions and statistical properties. In this context, "assembly" typically refers to the configuration of particles, energies, and other properties within a system. There are several types of statistical assemblies used to model different physical systems: 1. **Microcanonical Ensemble**: This is used for isolated systems with fixed energy, volume, and number of particles.
Biodiesel is a renewable, biodegradable fuel made from organic materials, primarily vegetable oils, animal fats, or recycled cooking grease. It can be used as an alternative to conventional diesel fuel derived from petroleum. The production of biodiesel typically involves a process called transesterification, where fats or oils react with an alcohol (usually methanol or ethanol) in the presence of a catalyst to form fatty acid methyl esters (FAME) and glycerin.
Green vehicles refer to environmentally friendly transportation options that are designed to reduce negative impacts on the environment compared to traditional vehicles that rely on fossil fuels. The term encompasses a variety of technologies and concepts aimed at promoting sustainability in transportation. Here are some key types of green vehicles: 1. **Electric Vehicles (EVs)**: These vehicles are powered entirely by electric batteries and produce zero tailpipe emissions. They are charged using electricity from various sources, ideally renewable energy.
Road congestion charge schemes are urban transportation management strategies designed to reduce traffic congestion in busy areas by imposing a fee on vehicles entering certain zones during peak hours. The primary goals of these schemes are to improve traffic flow, decrease air pollution, enhance public transport usage, and encourage the use of alternative modes of transportation, such as walking, cycling, or carpooling. ### Key Features of Road Congestion Charge Schemes: 1. **Charges**: Drivers must pay a fee when entering designated congestion zones.
ERating, or Emotional Rating, is typically used to assess the emotional impact or sentiment of a piece of content, such as text, audio, or video. This rating can be generated using various methods, including user feedback, machine learning algorithms, or sentiment analysis tools, to gauge how a specific content resonates emotionally with its audience. The term may also be used in various contexts, so its specific meaning can differ depending on the industry or application.
Road space rationing is a traffic management strategy used to reduce congestion and improve the efficiency of road transport systems. It involves limiting the amount of road space available for vehicles, often by implementing measures that restrict usage based on specific criteria. The aim is to encourage alternative modes of transportation, such as public transit, biking, or walking, and to optimize the flow of traffic.
Bioethanol for sustainable transport refers to ethanol produced from biological materials (biomass) that is used as a renewable fuel for vehicles. It is considered a sustainable alternative to fossil fuels because it can be produced from various plant materials, including sugarcane, corn, wheat, and other agricultural waste. Here are some key aspects of bioethanol in the context of sustainable transport: ### 1.
Carpooling is a transportation arrangement where multiple people share a vehicle to travel together to a common destination or along a similar route. This practice can reduce the number of vehicles on the road, lower transportation costs, decrease travel time, and minimize environmental impact by reducing emissions. Carpooling can happen informally, such as friends or coworkers driving together, or through organized platforms and apps that connect riders and drivers.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
