GC: n CT: Operating the locks and dams is a continuous job as tows and recreational boats can lock through all year long as weather conditions permit. The current 9-foot channel lock and dam system was built in the 1930s with an estimated life span of 50 years. The structures
GC: n CT: The objective of my research is to develop and refine environmentally sound silvicultural practices that enhance growth, development, quality and value of both individual trees and existing hardwood stands on the major river bottoms and minor streambottoms across the southern United States. Particular emphasis is placed on
GC: n CT: More often than not, the thought of rivers conjures up the image of high water levels and even floods. However, many communities depend on the availability of water through non-regulated river systems for their water supply. Therefore, periods of low flow are critical for managing their water
GC: n CT: In tidal waters, the intersection of the plane of mean low water with the shore. In this definition, it may be assumed that plane of mean low water means a horizontal plane through the average location of the water’s surface on a tide gauge during low water.
GC: n CT: Daylighting is recognized as an important and useful strategy in the design of energy efficient buildings. It is particularly useful in hot climates since it reduces the use of artificial lighting and thus electricity demand. Luminous efficacy is the parameter used to determine outdoor illuminance. In fact,
GC: n CT: Luminous flux is energy.The energy is the total amount of light energy radiated from a light source in all directions. The luminous flux is measured in lumens and is the parameter used to describe the “brightness” of a projector. One lumen is the Luminous Flux or expressed
GC: n CT: Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Machine learning is so pervasive today that
GC: n CT: Theoretically more interesting, though much more difficult, is the automatic grammatical analysis of texts by computer. Considerable progress was made in this area by research groups working on machine translation and information retrieval in the United States, Great Britain, the Soviet Union, France and a few other
GC: n CT: It is not always easy to distinguish between research and development or demonstration system and product in the area of Machine Translation (MT) however, it is useful to distinguish between fully automatic machine translation, human-assisted machine translation and machine-assisted human translation all of which fall within the
GC: n CT: Fusion Reactors: Magnetic Confinement There are two ways to achieve the temperatures and pressures necessary for hydrogen fusion to take place: Magnetic confinement uses magnetic and electric fields to heat and squeeze the hydrogen plasma. The ITER project in France is using this method. Inertial confinement uses
GC: n CT: One of the greatest challenges facing energy harvesters is generating enough power for practical applications. One way to increase the output power is to harvest more than one type of energy. For example, although there are a variety of devices that harvest either mechanical energy or magnetic
GC: n CT: Malware creation is on the rise due to money that can be made through organized Internet crime. Originally malware was created for experiments and pranks, but eventually it was used for vandalism and destruction of targeted machines. Today, much of malware is created to make a profit
GC: n CT: The user interface is often used in the context of computer systems and electronic devices. The user interface of a mechanical system, a vechicle, or an industrial installation is sometimes referred to as the Human-Machine Interface (HMI). HMI is a modification of the original term Man-Machine Interface
GC: n CT: Manure application to agricultural land involves the addition of all the components of the manure to the soil. An appropriate balance should be maintained between agronomic requirements and negative environmental impacts. Negative impacts, that could be defined as soil pollution, have to do with the addition of
GC: n CT: Companies measure capacity in different ways using either the input, output or a combination of the two as the measure. For example, a recycling company calculates their capacity based on the amount of material they clear from the inbound trailers at their plant, while a textile company
GC: n CT: Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Objects have mechanical energy if they are in motion and/or
GC: n CT: Megawatt (MW) is a metric measurement unit of power. The megawatt is equal to one million watts S: http://www.aqua-calc.com/what-is/power/megawatt (last access: 23 December 2014) N: 1. 1900, from mega- (before vowels meg-, word-forming element often meaning “large, great,” but in precise scientific language “one million” (megaton, megawatt,
CG: n CT: Recent satellite observations have shown the existence of a persistent layer of light-scattering particles in the vicinity of the polar mesopause during the summer. The suggestion has been made that this layer consists of ice particles, and that noctilucent clouds are a sporadic manifestation of the layer near
CG: n CT: Interestingly, the mesopause can be regarded as a layer separating two distinct dynamical regions of the atmosphere: the termosphere, where atmospheric processes are governed primarily by external solor influences, and the mesosphere, which is influenced primarily by internal variability produced by upward propagating waves.

CG: n CT: To hear tech CEOs like Mark Zuckerberg or Satya Nadella talk about it, the metaverse is the future of the internet. Or it’s a video game. Or maybe it’s a deeply uncomfortable, worse version of Zoom? It’s hard to say. It’s been nearly six months since Facebook
CG: n CT: Most meteor showers are spawned by comets. As a comet orbits the Sun it sheds an icy, dusty debris stream along its orbit. If Earth travels through this stream, we will see a meteor shower. Although the meteors can appear anywhere in the sky, if you trace
GC: n CT: Methane (CO4) is the second most prevalent greenhouse gas emitted in the United States from human activities. In 2012, CO4 accounted for about 9% of all U.S. greenhouse gas emissions from human activities. Methane is emitted by natural sources such as wetlands, as well as human activities
