Solution 1

a) Introducing slack variables, S1, S2, and S3 the given linear programming problem can be written in standard form as

Max 3A + 4B + 0S1+ 0S2+ 0S3

Subject to

-1A + 2B + S1 = 8

1A + 2B + S2 = 12

2A + 1B + S3 = 16

A, B, S1, S2, S3 ≥ 0

b) The feasible region is the shaded region OCDFG in the following graph.

image1.png

The coordinates of the feasible region and the corresponding objective function value is shown in the following Table

Extreme point Coordinates (A, B) Objective function
 

 A B 3A + 4B
O 0 0 0
C 8 0 24
D (20/3) = 6.67 (8/3) = 2.67 (92/3) = 30.67
F 2 5 26
G 0 4 16

Since the objective function is maximum at D, the point D is optimal.

Thus, the optimal solution is A = 20/3 and B = 8/3 and the optimal value of the objective function is 92/3 = 30.67.

c) At the optimal solution A = 20/3 and B = 8/3,

-1A + 2B + S1 = 8 implies -(20/3) + 2(8/3) + S1 = 8, that is (4/3) + S1 = 8 or S1 = 20/3.

1A + 2B + S2 = 12 implies (20/3) + 2(8/3) + S2 = 12, that is 12 + S2 = 12 or S2 = 0.

2A + 1B + S3 = 16 implies 2(20/3) + (8/3) + S3 = 16, that is 16 + S3 = 16 or S3 = 0

Thus, the values of the slack variables S1 is 20/3 and S2 and S3 are 0 at the optimal solution.

Solution 2

a) The decision variables are

X = Number of units purchased in the stock fund

Y = Number of units purchased in the money market fund

Since each unit invested in the stock fund has a risk index of 8, and each unit invested in the money market fund has a risk index of 3; the total risk index is 8 X + 3Y

Thus, an objective function that will minimize the total risk index for the portfolio is

Minimize 8 X + 3 Y

Since each unit of stock fund costs $50 and each unit of money market fund costs $100, the constraint corresponding to the available funds is

50 X + 100 Y ≤ 1,200,000

Since the annual income from stock fund is ($50)(10%) = $5 and the annual income from the money market fund is ($100)(4%) = $4, the constraint corresponding to the annual income is

5 X + 4 Y ≥ 60,000

Since at least $300,000 to be invested in the money market, at least ($300,000/$100) = 3,000 units must be invested in the money market. Thus, the constraint corresponding to the minimum units in money market is

Y ≥ 3,000

Finally, the non-negativity constraints, X, Y ≥ 0.

Thus, the linear programming problem is

Min 8 X + 3 Y

Subject to

50 X + 100 Y ≤ 1,200,000 (Funds available)

5 X + 4 Y ≥ 60,000 (Annual income)

Y ≥ 3,000 (Minimum units in money market)

X, Y ≥ 0

The Excel Solver output of the linear programming problem is shown below:

Data           Results  
  X Y       LHS Slack/Surplus
Objective 8 3 sign RHS   62000  
Constraint 1 50 100 < 1200000   1200000 0
Constraint 2 5 4 > 60000   60000 0
Constraint 3 0 1 > 3000   10000 -7000
               
Results X Y          
Variables 4000 10000          
Objective       62000      

Therefore, the optimal solution is X = 4,000 and Y = 10,000 and the minimum total risk index = 62,000.

Thus, Innis should purchase 4000 units in the stock fund and 10000 units in the money market fund to minimize the total risk index for the portfolio.

b) The annual income corresponding to the optimal investment strategy is

Annual Income = 5 X + 4 Y = 5(4000) + 4(10000)

= 20000 + 40000

= 60000

c) If the client desires to maximize the annual return, he should invest everything in the stock fund.

Solution 3

The decision variables are

X = Number of gallons of regular gasoline produced

Y = Number of gallons of premium gasoline produced

Since the profit contributions are $0.30 per gallon for regular gasoline and $0.50 per gallon for premium gasoline; the total profit contribution is 0.30 X + 0.50 Y.

Thus, the objective function is

Maximize 0.30 X + 0.50 Y

Since each gallon of regular gasoline contains 0.3 gallons of grade A crude oil and each gallon of premium gasoline contains 0.6 gallons of grade A crude oil, the constraint corresponding to the available Grade A crude oil is

0.30 X + 0.60 Y ≤ 18,000

The constraint corresponding to the production capacity is

X + Y ≤ 50,000

The constraint corresponding to the demand for the premium gasoline is

Y ≤ 20,000

Finally, the non-negativity constraints, X, Y ≥ 0.

Thus, the linear programming model is

Max 0.30 X + 0.50 Y

Subject to

0.30 X + 0.60 Y ≤ 18,000 (Availability of Grade A crude oil)

X + Y ≤ 50,000 (Production Capacity)

Y ≤ 20,000 (Demand for Premium)

X, Y ≥ 0

b) The Excel Solver output of the linear programming problem is shown below:

Data           Results  
  X Y       LHS Slack/Surplus
Objective 0.3 0.5 sign RHS   17000  
Constraint 1 0.3 0.6 < 18000   18000 0
Constraint 2 1 1 < 50000   50000 0
Constraint 3 0 1 < 20000   10000 10000
               
Results X Y          
Variables 40000 10000          
Objective       17000      

Therefore, the optimal solution is X = 40,000 and Y = 10,000 and the minimum total profit contribution = $17,000.

Thus, 40,000 gallons of regular gasoline and 10,000 gallons of premium gasoline should be produced to maximize the total profit contribution.

c) From the Excel solver output, the slack variables for constraints 1, 2 and 3 are respectively S1 = 0, S2 = 0, and S3 = 10000.

The slack variable for constraint 1, S1 = 0 means that all available grade A crude oil is used.

The slack variable for constraint 2, S2 = 0 means that total production capacity is used.

The slack variable for constraint 3, S3 = 10000 means that Premium gasoline production is 10,000 gallons less than the maximum demand.

d) The binding constraints are those constraints whose slack variables are zero. Therefore, Grade A crude oil availability and Production capacity are the binding constraints

Solution 4

The decision variables are

X = Time allocated to regular customer service during the two-week period

Y = Time allocated to new customer service during the two-week period

Since technicians require an average of 50 minutes for each regular customer and 1 hour = 60 minutes for each new customer, a technician can handle 60/50= 1.2 regular customers and 60/60 = 1 new customer in one hour, so that the total number of customers contacted during the two-week period is 1.2 X + Y.

Thus, the objective function is

Maximize 1.2 X + Y

Since a maximum of 80 hours of technician time is available over the two-week planning period, the constraint corresponding to the available technician time is

X + Y ≤ 80

The constraint corresponding to the cash flow requirement (revenue) is

25 X + 8 Y ≥ 800

Since the technician time spent on new customer contacts must be at leas 60% of the time spend on regular customer contacts, the constraint corresponding to this requirement is

Y ≥ 0.60 X

Or – 0.60 X + Y ≥ 0

Finally, the non-negativity constraints, X, Y ≥ 0.

Thus, the linear programming model is

Max 1.2 X + Y

Subject to

X + Y ≤ 80

25 X + 8 Y ≥ 800

– 0.60 X + Y ≥ 0

X, Y ≥ 0

b) The Excel Solver output of the linear programming problem is shown below:

Data           Results  
  X Y       LHS Slack/Surplus
Objective 1.2 1 sign RHS   90  
Constraint 1 1 1 < 80   80 0
Constraint 2 25 8 > 800   1490 -690
Constraint 3 -0.6 1 > 0   0 0
               
Results X Y          
Variables 50 30          
Objective       90      

Therefore, the optimal solution is X = 50 and Y = 30 and the maximum number of customers contacted = 90.

Thus, HTC should allocate 50 hours to regular customer service and 30 hours to new customer service to maximize the total number of customers contacted during the two-week period.

Solution 5

a) The feasible region is CBF

b) The co-ordinates of the point C are obtained by solving the equations 6X – 2Y = 3 and X+Y = 3. Solving these equations we get Point C (9/8, 21/8) = (1.125, 2.625)

The co-ordinates of the point B are obtained by solving the equations 6X – 2Y = 3 and -2X+3Y = 6. Solving these equations we get Point B(3/2, 3) = (1.5, 3).

The co-ordinates of the point F are obtained by solving the equations -2X+3Y = 6 and X+Y = 3. Solving these equations we get Point F(3/5, 12/5) = (0.6, 2.4).

The coordinates of the feasible region and the corresponding objective function value is shown in the following Table

Extreme point Coordinates (X, Y) Objective function
 

 X Y -3X + 6Y
C 1.125 2.625 12.375
B 1.5 3 13.5
F 0.6 2.4 12.6

Since the objective function is maximum at B, the point B is optimal.

c) The optimal solution is X = 1.5 and Y = 3 and the optimal objective function value is 13.5.

d) The binding constraints are 6X – 2Y ≤ 3 and -2X + 3Y ≤ 6.

e) Introducing slack variables S1, S2, and surplus variable S3, the linear program in standard form is

Max -3X + 6Y + 0S1+ 0S2 + 0S3

Subject to

6X – 2Y + S1 = 3

-2X + 3Y+ S2 = 6

X + Y – S3 = 3

X, Y, S1, S2, S3 ≥ 0

f) At the optimal solution X = 1.5 and Y =3,

6X – 2Y + S1 = 3 implies 6(1.5) – 2(3) + S1 = 3, that is 3 + S1 = 3 or S1 = 0.

-2X + 3Y+ S2 = 6 implies -2(1.5) + 3(3) + S2 = 6, that is 6 + S2 = 6 or S2 = 0.

X + Y – S3 = 3 implies 1.5 + 3 – S3 = 3, that is 4.5 – S3 = 3 or S3 = 1.5

Thus, the values of the slack variables S1 and S2 at the optimal solution are both 0 and the value of the surplus variable S3 at the optimal solution is 1.5.

Unit VIII Problem Solving Worksheet

This assignment will allow you to demonstrate the following objectives:

Describe thermodynamic concepts and their applications.

Extend the first law of thermodynamics to various daily life activities.

Identify the maximum efficiency of a heat engine.

Explain the role of latent heat while phases are changing.

Instructions: Choose 8 of the 10 problems below. Show your work in detail. Answer the questions directly in this template. Before doing this, it is highly recommending that you thoroughly review the four examples in the Unit Lesson.

The efficiency of a Carnot engine is e=1-Tc/TH, where Tc is a temperature of the cold reservoir and TH is a temperature of the hot reservoir. What is the condition to have 100% efficiency? Hint: What is the mathematical condition for Tc/TH to be zero.

Suppose the work done to compress a gas is 100 J. If 70 J of heat is lost in the process, what is the change in the internal energy of the gas? Hint: Use the first law of thermodynamics. The internal energy of a system changes due to heat (Q) and work (W): U=Q-W. The change in internal energy is equivalent to the difference between the heat added to the system and the work done by the system. Think if the work done is to the system or by the system. This determines the sign of W.

An engine’s fuel is heated to 2,000 K and the surrounding air is 300 K. Calculate the ideal efficiency of the engine. Hint: The efficiency (e) of a Carnot engine is defined as the ratio of the work (W) done by the engine to the input heat QH : e=W/QH. W=QH – QC, where Qc is the output heat. That is, e=1-Qc/QH =1-Tc/TH, where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir. The unit of temperature must be in Kelvin.

Mr. White claims that he invented a heat engine with a maximum efficiency of 90%. He measured the temperature of the hot reservoir as 100o C and that of cold reservoir as 10o C. Find the error that he made and calculate the correct efficiency. Hint: The efficiency (e) of a Carnot engine is defined as the ratio of the work (W) done by the engine to the input heat QH : e=W/QH. W=QH – QC, where Qc is the output heat. That is, e=1-Qc/QH =1-Tc/TH, where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir. The unit of temperature must be in Kelvin.

How much energy is needed to change 100 g of 0o C ice to 0o C water? The latent heat of fusion for water L=335,000 J/kg. Hint: The heat (Q) used to change from one phase to another phase of the matter is Q=mL, where L is the latent heat. Its unit is J/kg.

It was determined in the 19th century that the normal human body temperature is 98.6o F. A more recent study found that it is 98.2o F. Express the difference in the temperature in Celsius. Hint: Use the converting formula between Fahrenheit and Celsius scales: F=9/5C +32. Be careful about the unit.

Suppose 0.5 kg of blood flows from the interior to the surface of John’s body while he is exercising. The released energy is 2,000 J. The specific heat capacity of blood is 4,186 J/kgo C. What is the temperature difference between when the blood arrives at the body surface and returns back to the interior of the body? Hint: Use the formula regarding heat Q, specific heat capacity c, mass m, and temperature change dT. Q= cm dT. Please look at p.290 in our textbook. Also, review Example 1 with its solution in Study Guide.

A student does 1,000 J of work when she moves to her dormitory. Her internal energy is decreased by 3,000 J. Determine the heat during this process. Does she gain or lose her heat? Hint: Use the first law of thermodynamics. The internal energy of a system changes due to heat Q and work done W: U=Q-W. Also, look at a similar case, Example 3 with its solution in Study Guide.

In a construction site, 2 kg of aluminum shows the increment of temperature by 5oC. Ignoring the work, what is the change in the internal energy of the material? The specific heat capacity of aluminum is 900 J/kg oC. Hint: The internal energy of a system changes due to heat Q and work done W: U=Q-W. If we ignore, the work, the internal energy U is identical to the heat Q of the system. We know that relation between heat Q, specific heat capacity c, mass m, and temperature change dT; Q= cm dT. That is, U=Q=cm dT.

The input heat of a Carnot engine is 3,000 J. The temperature of a hot reservoir is 600 K and that of a cold reservoir is 300 K. What is the work done? Hint: The efficiency e of a Carnot engine is defined as the ratio of the work done, W, by the engine to the input heat QH : e=W/QH. W=QH – QC, where Qc is the output heat. That is, e=1-Qc/QH =1-Tc/TH, where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir. The unit of temperature must be in Kelvin.

Use the formula, e=1-Tc/TH. Please review the Example 4 with its solution in Study Guide. Once you evaluate, you can find the work done of the system using the formula, e=W/QH

Discusion -01-Epid

/in /by

Discussion 1-3 EPid ( two pages)

Because it draws from other fields such as biostatistics and social sciences, epidemiology is described as being interdisciplinary. From which aspects of other disciplines do you feel epidemiology borrows? In what ways does epidemiology differ from those disciplines? When responding to your classmates, provide additional connections between epidemiology and other disciplines. Support your response with specific examples.

Response one

Epidemiology and Other Disciplines

Epidemiology is the “study of the distribution and determinants of health and disease, morbidity, injuries, disability, and mortality in populations” (Friis & Sellers, 2014, p. 743).  Epidemiology was first developed to understand causes of certain diseases such as smallpox and polio among humans. It now also includes the study of factors associated with non-transmissible diseases like cancer. It is described as interdisciplinary as it borrows elements from many other disciplines including microbiology and sociology. Epidemiology utilizes microbiology to help understand specific disease agents and modes of transmission. Microbiological techniques are borrowed to help in revealing sources of outbreaks and to determine sources. Sociology is equally important in epidemiology to aid in the study of social conditions and disease processes. Social sciences also assist epidemiologists in providing different methods on sampling such as measurement, questionnaire development, design, and delivery (Friis & Sellers, 2014). “Social factors have become more important precisely because epidemiological and biomedical knowledge has shifted the causes and consequences of disease from fate, accident, and bad luck to factors that are under some human control” (Link, 2008, p. 367).

Epidemiology differs from other disciplines in its perspective on groups or populations rather than individuals. It contrasts diseases and characteristics relative to different time periods, different places or different groups. It also differs from the physical sciences because it does not investigate the biological mechanism leading from exposure to disease. Epidemiologists can identify modifiable conditions that contribute to the health outcome without also identifying the biological mechanism or agent that lead to the outcome. An example of this is the improvements of environmental hygiene that reduced infectious diseases like cholera, that was possible before the identification of the actual bacteria (Ahrens, Krickeberg, & Pigeot, 2005).

Epidemiological studies are crucial to preventing, controlling and eradicating diseases. The research helps us to understand the incidence and prevalence of diseases, the cost of illness, and the burden of disease on society (Friis & Sellers, 2014). I have attached an article that I read about the role of mathematical modeling and prediction in infectious disease epidemiology that I felt was interesting and relevant to our Epidemiology course.

Questions To Answer

/in /by

READ CAREFULLY !!! YOU MUST watch the videos in order to answer the 4 questions.

You need to listen to video lectures on Line, Shape and Space.  You’ve also need to view the approx. 12 minute video segments on Vija Celmins, Doris Salcedo, and Julie Mehretu.  I will post a LINKS for all the lectures and videos at the bottom. Again you must see them in order to answer the following questions.

Answer the following questions (MINIMUM OF 550 WORDS)

1)  Which artist’s work did you find most interesting?  Why?

2)  How did her work relate to the ideas of Shape or Space in Chapter 4?  Both in technical terms, but also conceptually.

Be specific here by using vocabulary from the textbook.  I’m looking for you to be able to apply the language and concepts from the book to the specific works shown in the videos.  Can you expand on the just the actual presence of shape and space and apply these formal elements to their main concept?  Make sure you cite specific works from the video.

3)  How did her work relate to the ideas of Line in Chapter 3?  Both in technical terms, but also conceptually.

Again, be specific by using the terminology from the textbook.  Also, see if you can push the formal element of line to apply to the main concept of the artist.

4)  Compare your answers to questions 1 – 3 with one of the other two artists.  Did this other artist use Shape, Space, or Line differently?  How?

Make sure you cite specific works from the video.

YOU MUST CITE SPECIFIC WORKS FROM THE VIDEO ONLY or the book !
