Excavation is an important job in mining, earth removal and general earthworks.
Excavation output (amount of work done), efficiency (cost of work done in expressions of labor and machinery) and operator safety, mainly in underground mining or in the removal of hazardous waste are constantly under pressure from industry. After decades of increasing in machine size and power, now practical limits are being approached and automation is being required for further improvements. In addition, computing and sensing technologies have reached to a phase where they can be applied to automate the excavation process.
The construction of highway, digging of trench, holes and foundation are required quick removal of the soil. Usually digging machines such as backhoe loaders also well-known as

Backhoe excavators are used mostly to excavate under the natural surface of the ground on which machine rests. A backhoe excavator is really three pieces of construction equipment combined into single unit which are known as a tractor, a loader and a backhoe as shown in Fig. 1.1. A backhoe also famous as a backhoe excavator attachment is the area of research. A backhoe is the main link mechanism of the backhoe excavator to perform excavation task. It consists of a digging bucket on the end of a two part articulated arm (Fig.
After reading the article "Rethinking our Roots" by Russ Juskalian; it touch many different topics thorough out it. One of these topics was the discovery of Little foot which all began by Ron Clarke, who was looking through mislabeled boxes that were from the 1920 's and 30 's gold rush and found a small human like ankle bone. Which lead to to excavation of the rest of the skeleton. According to Clarke ( Juskalian 2016) about little foot was that it, "was made for walking up straight and it didn 't drags it knuckles(p. 32). The next topic that was discussed was the discovery of Karabo that was discovered by Matthew Berger and how was it was structured.
In the essay “On Dumpster Diving”, the author Lars Eighner informs us about the art of dumpster diving. The writer, who speaks from personal experience of gathering things from dumpsters, prefers to be called a “scavenger” rather than “foraging” for scavenger, in the writer’s opinion, has an honorable meaning for doing something that takes skills and experience. In the beginning, Mr. Eighner demonstrates the stages that any new dumpster diver goes through. Feeling of shame and Self-hatred is the first phase which the author explains as they hate to be seen. However, after they realize how perfectly good stuff people throw in dumpsters, they become obsessed by gathering anything their hands lay on.
The extension appears to have no blunt ends and can be described as large swirls that represent the clouds in a storm or streams of water. The extension has remnants of its once vibrant blue paint still intact on the left side of the piece. If the statue is viewed directly from the front the extension appears as a thin column of rectangles stacked along the middle of the nose. However, from the side the protruding nature of the extension are apparent if observed from various standing angles. The extension flows seamlessly with the accompanying statue elements due to the it’s smoothness and overall
They shoveled loose dirt into boxes then ran it under water causing heavy minerals, like gold or silver, to sink to the bottom; this worked well in finding loose gold that washed out of the rocks. Long drives was the transportation of cattle; the job of cowboys, from ranges into cow towns.
Heavy mechanism are tractors and heavy electronic equipment. In farming they used heavy mechanisms to farm better and graze more land. As it shows in document C and D, heavy mechanisms were used a lot in order to make farmers earn more money because of how much land they can farm. The more land, the more money a farmer can earn.
The steel plow was used break through the hard topsoil of the western plains. Windmills were used to get water out from underground for people with little access to water. The mechanical reaper reduced farm labor and increased the production of wheat and other plants (Allison 149). Westward Expansion had many positive effects such as job opportunities from the Oregon trail and the California Gold Rush, and all of the land that the U.S gained during Westward

Over the course of the 1960’s James Arthur Baldwin emerged as one of the great influencers of writing regarding problems of society. James was born August 2nd, 1924 in Harlem, New York City to his single mother Emma Jones (F). James’ first novel composed was “Go tell it on the mountain” published in 1953, with multiple short stories speaking out about racial segregation and political influences on minorities of today’s world (P). James Baldwin was a late twentieth century author who presented racism, sexuality, and culture to persuade his readers to be more open to these issues and encourage them to fight for equality. Through “Sonny’s Blues” and “The Rockpile”, Baldwin expresses his concern about temptation, suffering, and isolation by making the

Due to automation and robotics, around five million jobs exist with 300,000 people estimated to already be employed in industrial robotics.
Introduction: The term 'advanced development technology ' in construction industry covers an extensive variety of present day techniques and practices that envelop the most recent improvements in materials technology, design methodology, amount studying, offices management, administrations, structural examination and design, and management skills used in construction industry. Technological advancements in different fields such as medical industry, business industry, electrical engineering, mechanical engineering, civil engineering etc. have brought many positive impacts. Fusing advanced development technology into construction industry can expand levels of value, proficiency, safety, maintainability and incentive for money. The advanced technologies in construction industry are very useful for all type of small and large scale construction projects.
Many jobs have become easier by being replaced by robots. Robot are not just the idea of talking mechanical parts as we see in futuristic movies. There are a variety of different types of robotic machines, great majority of them appear in factories and in science technology work fields. Robots in factories help replace a dangerous parts of a job. However, there have been different perspective with robots replacing jobs.
An introduction to highway building: Although there are many methods to constructing a road, all are based on the principle that geographical objects are removed and replaced with harder and more wear-resistant materials. The pre-existing rock and earth is removed by digging or explosions. Tunnels, embankments and bridge are then added when necessary. The material that the road is being constructed from is then laid by various pieces of equipment, which will be looked at in greater detail in this assignment. The construction management of roads has become increasingly more difficult as larger structures are constantly being required in increasingly short amounts of time.
