This document discusses various techniques for storing electrical energy, including batteries, compressed air, flywheels, pumped water, and hydrogen storage. It focuses on using hydrogen produced by hydrolysis as an energy storage method. When excess energy is generated, it is used to produce hydrogen through electrolysis. During energy deficits, the stored hydrogen is reconverted to electricity through fuel cells. The document outlines the benefits of hydrogen storage such as high energy density and lack of carbon emissions, as well as safety testing procedures.
Ruby is a wonderful language for rapid development, it is easy to learn, we have wonderful frameworks, an active and dynamic community. But when it comes to concurrency Ruby is plagued with problems, controversies and urban legends. A lot of people would know about green threads in Ruby, GIL and its inherent limitations. But that it only one part of the big picture. Ruby offers much more than threads to helps us with concurrency.
This presentation explores other options of writing highly concurrent applications in Ruby and options available in it. We cover topics ranging from Actor like message passing concurrency in Ruby, dataflow concurrency of how we can coordinate across different threads, Event driven methods, coroutine based concurrency which never blocks ;) and finally Software Transactional Memory. We look at lots of code, some serious looking yet colorful performance graphs comparisons, and conditions at which each of these forms are concurrency are effective and ineffective.
The document discusses computer clothing being adopted by militaries. Computer clothing, also known as wearable computers, are small portable computers integrated into ordinary clothing. The U.S. Armed Forces are adopting wearable computers attached to or integrated into a soldier's clothing. These computerized uniforms allow soldiers to track enemy targets, monitor their health, translate languages, and enhance communication and navigation. While computer clothing provides advantages like improved communication and training, it also faces challenges like short battery life and integrating many components into a lightweight package.
How to turn liquid waste into power. Heated sludge is mixed with help of sliding vane compressors by gas discharged through floor-level diffusers. Generated biogas is transferred into storage and then sent to combined heat and power unit for conversion to heat and electricity.
A gyrobus is an electric bus that uses a large flywheel instead of overhead wires to store rotational energy. The flywheel spins at up to 3,000 RPM and can power the bus for 5-6 km between 30 second to 3 minute recharging stops. Developed in the 1940s, gyrobuses faced challenges due to their large flywheel weight and complexity of controlling a spinning gyroscope within the bus. Modern power electronics and materials could help address some of the historical issues with gyrobuses.
What Counsel Should Know About Green BuildingChris Cheatham
This document summarizes a presentation on green building and surety law. It discusses how performance bonds required by green building regulations may not be appropriate instruments. It also notes potential issues that can arise from green building certification requirements, called "LEEDigation," such as disputes over a building's actual energy efficiency. The presentation provides an overview of surety law principles and analyzes different enforcement mechanisms for green building standards, recommending alternatives to performance bonds like financial security requirements.
This document presents information on electronic noses. It discusses that electronic noses are devices that detect odors and flavors using sensor arrays and pattern recognition systems, similarly to how humans sense smells. The three main parts of an electronic nose are a sample delivery system to introduce headspaces, a sensor detection system of sensors like MOS that react to volatile compounds, and a computing system to analyze the sensor responses. Electronic noses are used in various applications like research and development, quality control, and production to analyze samples and odors.

Nanowires are microscopic wires that have widths measured in nanometers, ranging from 40-50 nanometers. They have potential applications in electronics, energy storage, sensing and optoelectronics due to their unique properties. Specifically, semiconductor nanowires and carbon nanotubes have shown promise as building blocks for future nanoscale devices and circuits due to their ability to efficiently transport electrical carriers and exhibit critical device functions. However, carbon nanotubes have faced challenges in controlling their semiconducting or metallic properties and manipulating individual tubes, while nanowires allow for more rational and predictable assembly through control of their synthesis.

The advantages and applications of trenchless technology in India are also summarized.
This document provides an overview of electronic noses. It defines an electronic nose as a device that detects odors or flavors using an array of sensors that generate electrical signals in response to volatile compounds. The document then discusses the basic design of an electronic nose and how it works, comparing it to the biological nose. It also outlines common sensor technologies, applications such as medical diagnosis and food quality control, and concludes that while not as sensitive as the mammalian nose, the electronic nose is a useful analytical tool.
Biomass is a renewable energy source derived from living organisms. It can be used to generate electricity through combustion in a biomass power plant. There are different modes of biomass power generation including direct combustion, gasification combustion, mixed burning with coal. Biomass power plants provide social and economic benefits like job creation and reduced dependence on foreign energy sources. While prospects are strong in industrial sectors that produce biomass waste, challenges include securing stable long-term fuel supplies and electricity prices that support plant viability.
E-paper is a display technology that mimics the appearance of ordinary ink on paper. It was developed in the 1970s and uses microcapsules filled with charged pigment particles. When an electric field is applied, the particles move to the top or bottom, allowing the color to be changed. E-paper has advantages over LCD displays in having a wide viewing angle, being readable in sunlight, and not requiring power to hold an image. It is used in e-readers, e-newspapers, mobile displays, and could replace paper in the future.
Since the loads having the trends towards growing density. This requires the better appearance, rugged construction, greater service reliability and increased safety. An underground cable essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. The interference from external disturbances like storms, lightening, ice, trees etc. should be reduced to achieve trouble free service. The cables may be buried directly in the ground, or may be installed in ducts buried in the ground.
Energy transfer in the atmosphere and oceansmgcimariam
The document discusses various ways that energy is transferred within the atmosphere and between the atmosphere and oceans/land. It describes how the sun's radiation is absorbed, reflected, scattered, or transmitted by gases in the atmosphere. Thermal energy is also transferred via conduction, convection, and radiation. Convection currents globally distribute heat. Prevailing winds are influenced by these currents. Ocean currents similarly redistribute warm and cold water around the world through processes like the global conveyor belt. Latent heat absorption and release also influences global climate patterns.

The document discusses electronic noses (e-noses), which aim to mimic the human sense of smell. E-noses consist of sensor arrays that detect odors and pattern recognition systems that interpret the sensor readings. They have various applications in areas like environmental monitoring, quality control, and medical diagnosis. While e-noses have advantages over human smell in speed, accuracy, and ability to detect hazardous substances, challenges remain in fully replicating the human olfactory system. Future improvements to sensor arrays and neural network techniques may lead to more advanced electronic noses.
