(a) Develop a landing sequence that gives priority to those aircraft with the highest cost of slack time (excess flying time multiplied by cost per minute of flying time). For example, Flight 616’s 18.75 minutes of slack time (22 – 3.25) times $300 per minute means that if Flight 616 does not land until its time is all used up, it incurs an extra flying cost of $5,625. Make a Gantt chart showing the landing sequence and evaluate the sequence in terms of performance. Calculate mean flow time, mean lateness, and average number of planes in the system.(b) Develop a sequence using SPT as a priority rule. Make a Gantt chart showing the landing sequence and evaluate the sequence in terms of performance. Calculate mean flow time, mean lateness, and average number of planes in the system.(c) Develop a third sequence using EDD (earliest due date) as a priority rule. The plane with the least amount of flying time remaining has the highest priority. Make a Gantt chart showing the landing sequence and evaluate the sequence in terms of performance. Calculate mean flow time, mean lateness, and average number of planes in the system. Calculate the total cost associated with this sequence (flow time multiplied by cost per minute of flying time for each flight).(d) Try to develop an alternative sequence that lands all of the aircraft safely and reduces the total cost.

The following data was collected by a Civil Engineering Ph.D. student. The response variable is the number of deer-vehicle crashes given a half-mile section of highway located in Ashtabula County. The half-mile sections were supposedly scattered about the community. Find an appropriate model which will be useful in predicting the number of deer-vehicle crashes using the candidate regressor variables. Interpret your results.

X1 = number of vertical curves in the half-mile section

X2 = number of horizontal curves in the half-mile section

X3 = number of ditches in the half-mile section

X4 = number of residences in the half-mile section

X5 = number of driveways in the half-mile section

X6 = percent of half-mile section that was adjacent to forest land

There are 20 observations total.

See the data below.

Research one legal case or recent event involving a tort and one legal case or recent event related to criminal law. Each case or event should have taken place within the past two years.

Write in-depth briefs explaining your selected cases using the IRAC method.

Each case brief should be 350 to 525 words and include an explanation of how the legal concepts in the selected case can be applied within a managerial business setting including considerations such as but not limited to:

  • Insurance
  • Internal auditing and reporting procedures
  • Explaining what could have been done differently in each case to avoid or reduce harm/risk

write my assignment 5499

 cantilever hollow beam of 2 m long is shown in Figure 1. The hollow section is consisted of one rectangle and two half circles. The thickness of the outer wall is 10mm while that for the inner walls is 5mm. The dimensions of the hollow section are shown in Figure 2. The beam is subjected to torsional moment of 50kN.m and bending moment of 40 kN.m. Consider G= 83 GPa.

(1) Determine the normal and shear stresses at points A and B on the outer surface of the beam and show them on sketches.

(2) Calculate the angle of twist of the tube at point C.

(3) Calculate the principal stresses, maximum shear stress and the orientation of principal planes and shear plane at the same points as in part (1). Show also the principal stresses and the maximum shear stress on sketches.
