robotjoints.f implements the needed solution. You need to be able to look at robotjoints.f and already have a pretty good understanding how it’s all works. We will research about the each individual line in the program in just a few seconds.

!     shouldera and shoulderb are the A and B coordinates of the shoulder joint.

      elbowa = shouldera + (robotarm * sin(alphar))
      elbowb = shoulderb - (robotarm * cos(alphar))

!     Print out the results.

      print *, 'The A coordinate of the elbow joint is ', elbowa
      print *, 'The B coordinate of the elbow joint is ', elbowb
      
      end
      
!     End of file.

Take a moment to read the program and try to understand how it determines the position of the robotic elbow joint. No need to worry if you don’t “know” how to program Fortran. Using your own knowledge of the problem, you should be able to figure out, more or less, what the programs do and how they do it.

A Back Tangent Of +4% Gradient Meets With A Forward Tangent Of -3% Gradient In A Vertical Curve. Station And…

/in /by

A back tangent of +4% gradient meets with a forward tangent of -3% gradient in a vertical curve. Station and elevation of Point of Vertical Intersection (PVI) are 70+00 and 270 ft, respectively. Horizontal length of the curve is 1000 ft. Calculate the elevation and tangent offset at station 74+00. Also, calculate the station in the curve that has maximum elevation, and corresponding maximum elevation.

Ecosystem And Community Structure

/in /by

The final paper will combine the ecological concepts from the course under one analysis: ecosystem and community ecology. The overall objective is to understand how the biotic and abiotic factors influence the physical and biological structures of ecosystems and the communities within them. This knowledge is fundamental for developing effective policy, and managing wildlife and habitats.

To begin the assignment, select one of the following ecosystems. Then, address the questions below. Analyzing ecological communities can be accomplished by taking apart all of the physical and biological pieces that make up an ecological community, and then relating them back to one another in order to understand how they interact to form a functioning system. Conclude the paper with an assessment of human impacts on your selected ecosystem and how this will affect the ecology and future adaptation capabilities of the species in your community. Reference your textbook and a minimum of six scholarly sources (i.e., academic journal research articles) to provide examples and evidence that support your main points.

Before beginning the assignment, be sure to read chapters 16 through 18 on community ecology carefully and to learn more about specific ecosystems, review chapters 23 through 25 in the course text, Smith, T.M. & Smith, R.L. (2015). Elements of Ecology. 9th  edition. MA: Pearson.

Step 1: Choose one ecosystem to analyze.

Lakes and ponds

 

Step 2: Address the following points in your paper.

  • Describe the physical structure of the selected ecosystem and explain how structural factors come together to create the ecosystem. The physical structure refers to the abiotic (non-living) components—such as temperature, precipitation, bedrock, soil type, riverbed or ocean floor, boulders, and topography—that make up your ecosystem.
  • Describe the biological structure of your selected ecosystem. Explain how life forms come together to shape your ecosystem. The biological structure is how the ecosystem is shaped by plants and animals, and it includes forest levels and coral reef structures. It also includes the overall level of diversity, species composition, and dominant plant and animal species with details about niche, height, size, density, and/or function.
  • Analyze the function of the selected ecosystem by indicating how the physical and biological structures are related to the ecosystem’s productivity (i.e., the amount of biomass produced), complexity of food webs, nutrient availability, and nutrient cycling.
  • Explain the process of succession in your selected ecosystem.
  • Describe one mutualistic interaction in your selected ecosystem. Explain the role that each species has in the interaction and the resulting mutual benefits to each species population. In other words, what does each species give and what does each one get in return.
  • Describe one predator-prey (or plant-herbivore) interaction. Explain how this interaction impacts the ecological community as a whole. Evaluate the magnitude of human impact on your ecosystem. This includes how humans are affecting the physical structure and species in your ecosystem. Predict whether the species and their interactions presented in your paper will be able to adapt to these changes. For example, what would happen to pollinators in a plant-pollinator mutualism, if plants are destroyed due to urbanization?

 

Must be 8 to 12 double-spaced pages in length (not including title and references pages) and formatted according to APA style

 

  • Include an introduction stating your selected aquatic and terrestrial ecosystem followed by an overview of topics that will be discussed.
  • Include a summary of the main points discussed in the paper, with particular attention to ecosystem function and the future of your selected ecosystem.
  • Must use at least six scholarly sources (i.e., academic journal articles) in addition to the course text.

ATTCHED ARE THE CHAPTERS NEEDED. ATTACHED IS THE OUTLINE ALREADY ESTABLISHED. ATTACHED IS THE GRADING RUBICS( READ IT SO YOU KNOW WHAT NEEDS TO BE DONE) ATTACHED IS THE CORRECTIONS FOR THE OUTLINE ( READ THEM SO YOU KNOW WHAT NEEDS TO BE FIXED).  MUST USE SIX (6) SCHOLORLY RESOURCES PLUS THE ATTACHED TEXT FOR A TOTAL OF 7 RESOURCES. MUST BE DONE ON TIME AND DONE RIGHT THE FIRST TIME PLEASE!!!

SCI 201 | Assignment 3: Environmental Issues And The Industrial Revolution

Assignment 3: Environmental Issues and the Industrial Revolution

The Industrial Revolution, which began in the eighteenth century, has had an ongoing influence on society as well as the relationship between humans and their environment. With the onset of industrialization came the drastic increase in urbanization, setting up of factories in places which were once biomes, and the rapid development of land. All this occurred without assessing the long-term impact to the environment. Recognizing the importance of the Industrial Revolution era and the ongoing impact it has had on the environment is essential to learning how to help the environment and correct the damage of that era.

Using the readings for this module, the Argosy University online library resources, and the Internet, complete the following:

  • Identify three of the most environmentally negative impacts of the Industrial Revolution and justify your choices. For example, the invention of the automobile revolutionized travel in a positive manner. However, this invention is causing some of the biggest environmental problems as a result of the extensive use of oil extracted from the earth.
  • Examine how these three negative impacts changed the environment; list the mechanisms through which this happened. For example, factories caused an increase in pollution through the release of toxic waste, which led to diminished and lost fish populations in rivers.
  • Explain the effect of the environmental movement on the process of industrialization in the United States during the 1970s.
  • Identify the laws passed to help ameliorate the environmental issues in the U.S. or around the world related to these three impacts. Have any laws been passed since this movement in the 1970s? If there have been laws implemented, summarize the spirit of the law and comment on the effectiveness of the law.
  • Based on your research, examine whether the state of the environment has become worse or has improved as a result of these laws. Suggest steps to improve the environmental situation.

Support your statements with appropriate examples and scholarly references. Be sure to include an additional page for references.

Write a 4–5-page paper in Word format. Apply APA standards to citation of sources. Use the following file naming convention: LastnameFirstInitial_M1_A3.doc. For example, if your name is John Smith, your document will be named SmithJ_M1_A3.doc.

By the due date assigned, deliver your assignment to the Submissions Area.
