Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

The concept of probabilistic design is quite pervasive across the engineering disciplines because of its implication on engineering design decisions. Typically, assumptions and simplification of engineering and other related natural processes are often idealistic and do not consider uncertainties inherent in those processes and phenomenon (be they mechanical, chemical, electrical, biological, etc). There is also the tendency to assume that the situation is either deterministic or qualitative or both. Under certain circumstances such assumptions may suffice. However, in the realm of engineering design, such assumptions and simplifications are not acceptable as uncertainties are unavoidable in almost all engineering analyses and design activities. Thus, any recommendations that are formulated without proper identification and assessment of the inherent risks and uncertainties would not only be invalid but would paint a wrong picture of the situation under consideration.

The purpose of this course therefore is to present the fundamental concepts of probability and statistics from the perspective of engineering practice. As part of the learning objective, the course would demonstrate:

The role of probability and statistics in engineering design decisions, and
The concepts of variability

Additionally, the student will be able to:

Develop an appreciation of the notion of events, the sample space and the real line.
Understand the notion of enumeration and counting techniques that are applicable in probability and statistics analyses.
Explore the meaning of density and mass functions with respect to their relationship to random variables.
Discover some of the common discrete and continuous distributions that are employed in describing engineering problem situations and scenarios

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

The concept of probabilistic design is quite pervasive across all engineering disciplines because of its implication on engineering design decisions. Quite often because of the complexity of the processes and the difficulty in explicating the inherent relationships, assumptions about engineering and other related natural processes are simplified and so do not consider uncertainties inherent in those processes and phenomenon. Safety factors and safety margins have often been employed to overcome the need for probabilistic designs. Under certain circumstances such assumptions may suffice. However, in the realm of engineering design, such assumptions and simplifications may not be acceptable as uncertainties are unavoidable in almost all engineering analyses and design activities. Therefore any recommendation developed without proper identification and assessment of the inherent risks and uncertainties would not only be invalid but would paint an unrealistic and unrepresentative picture and thus could jeopardize public safety.

This second course in the series focuses on an important area of engineering analyses and design, namely Statistical Inference. Statistical Inference is about how we analyze data and use the information to make decisions about a given engineering problem. The process of explicating the complexities of the data to yield information that would eventually be used to make design or mission decisions is known as inference or more appropriately Statistical Inference. If we examine the relationship between the population and the sample (as we did in the first course) we note that there is sort of a symbiotic (parent-population, offspring-sample) relationship between the two. Probability deals with the population with its parameters (parent values) while Statistical Inference deals with the sample and its statistic (values computed from the sample and used to estimate the population or universe parameters). The following areas would be covered in the course but not necessarily in the order shown:

The Point Estimates for the Mean and the variance.
The Central Limit Theorem (CLT) and its role in estimating parameters of a population.
Sampling distributions for means and variances with variance both known and unknown
Sampling distribution for two means & two variances with variance known and unknown
Point Estimator, Interval Estimators and Tests of Hypothesis
Error of estimation and the effect on sample size (n).
Type I and Type II errors and the effect on ample size n
Confidence Intervals for one means and one variances
Confidence Intervals for two means and two variances

Due to the nature of the materials, a significant number of numerical examples have been included to provide better insight into the materials presented. At the end, the engineer should feel well equipped to explore the important area of Statistical Inference and what it offers with regards to Engineering design decisions.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Design of experiment is an activity that every Engineer should take very seriously. Engineers are called upon every day to make decisions regarding programs, processes and systems that have significant implications on the safety and well-being of society, be they chemical processes, the environment, infrastructure, machinery and equipment, and others. And while Engineers are known for sound and fact based judgment, those laudable qualities and characteristics may not be enough and may not serve them well in certain circumstances. This is especially true when they are called upon to make decisions regarding variables and factors whose underlying distributions are stochastic and thus have uncertain, albeit questionable, predictability. Handling these situations requires an understanding of the formal schemes and structures necessary to deal with variability, bias, and randomness.

This is the first of a two-course sequence in this subject area. As the prerequisite to the second course, it provides the Engineer with the rudimentary, but necessary, toolkit needed to plan, design and analyze basic engineering experiments and to make recommendations about design and operational decisions. It sets the stage for the second course, where more robust and higher level designs are explored, including Factorial designs, Fractional designs, Nested designs, Confounding schemes and Regression Analysis. The second course also addresses a fundamental problem of design, namely cost and resource utilization, and also the all important issue of missing values. While the two courses are not strictly about mathematics and statistics, they do utilize those subject matters to further elucidate how to plan, design, and analyze engineering experiments. Some of the areas covered in this course include:

The Role of Experiments in the Engineering Design Process
The Role of Statistics and Probability in Engineering Design
Purpose and Nature of Planned Experiments
Important Issues in Planned Experiments
The Effects of Changes in the Independent Variables
The Effect of Noise in An Experiment
Restrictions on Randomization
Single Factor Experiments including Model Analysis
Randomized Block Designs
Latin and Other Designs
Incomplete Block Designs

Course Description:

Design of experiment is an activity that every Engineer should take very seriously. Engineers are called upon everyday to make decisions regarding programs, processes and systems that have significant implications on the safety and well being of society, be they chemical processes, the environment, infrastructure, machinery and equipment, and others. Engineers are known for sound and fact based judgment but while those qualities and characteristics are laudable, they may not be enough and may not serve them well. This is especially true when they are called upon to make decisions regarding variables and factors whose underlying distributions are stochastic and thus have uncertain and questionable predictability. Handling these situations requires an understanding of the formal schemes and structures necessary to deal with variability, bias, and randomness.

This second course, in the two-course sequence, focuses on some of the more practical issues that engineers encounter during the design and analysis of experiments. This course focuses on more robust and higher level designs such as Factorial designs, Confounding Schemes Fractional designs, Fixed and Random factors, Expected Mean Squares, Nested or Hierarchical designs, and Regression Analysis. The course also addresses, with realistic examples, some of the common problem in design of experiments, namely, missing data or missing values. It also provides practical justification for confounding, which arises due to the physical limitation as it relates to acquiring all the needed data. It addresses the issue of cost and resource utilization where fractional factorial designs are used because the cost to run full higher order designs is prohibitive. The course has a very practical bent and while there are theoretical foundations undergirding the material, the course itself utilizes basic arithmetic for computation and analysis. Some of the areas covered in the course include:

The Role of Experiments in the Engineering Design Process
Missing Values for Randomized Block and Latin Designs
Factorial Designs for 2^f and 3^f
Confounding Schemes for 2^f and 3^f
Fractional Factorial Designs for 2^f and 3^f
Modeling of Fixed and Random Effects and Expected Mean Square (EMS)
Nested/Hierarchical Designs

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Metal plated wood trusses are engineered products that are manufactured in a controlled environment and are now used extensively in the wood frame construction industry. Wood trusses provide the architect or building designer greater flexibility in the design of the structure than conventional framed (stick-built) construction. The design is not as limiting with regard to bearing wall locations which enables longer spans and greater ability to shape complicated roof and ceiling profiles. These pre-manufactured wood trusses facilitate a quicker construction schedule and an overall lower cost.

Wood, a renewable resource, has a great deal of manufacturing flexibility. Wood members are easily formed into standard framing sizes, cut into appropriate lengths with odd angles if necessary, and attached to form the wood structure. However, wood is more susceptible than steel or concrete to damage due to internal defects, handling issues, and long term deterioration. Design or manufacturing errors, shipping damage, miscommunication, and change orders are possible causes for the inadequacy of a wood truss for a specific application and therefore a repair or modification of the pre-manufactured wood truss is required. The purpose of this document is to address various repair techniques that could be used to correct damage to the wood members or metal plates, reinforce trusses that do not meet the required specified design loads, or adjust the truss profile or member location to meet other design requirements.

This course is the second part in a three part series which consists of a total of 11 chapters between all three parts. Chapters 1 through 3 provide an introduction to the terms, concepts, and process involved in truss repairs. Chapters 4 through 11 contain actual truss repairs to provide instruction through the use of example. These chapters are broken down as follows:

Part 1: Introduction and Simple Repair Concepts — Five Chapters

Chapter 1 — Definitions
Chapter 2 — Repair Design Concepts
Chapter 3 — Wood Truss Repair Connections
Chapter 4 — Member Damage and Defects
Chapter 5 — Plate Damage

Part 2: Moderate Truss Repairs - Four Chapters

Chapter 6 — Manufacturing Errors
Chapter 7 — Stubs and Extensions
Chapter 8 — Minor Modifications
Chapter 9 — Major Modifications

Part 3: Complex Truss Repairs - Two Chapters — Current Part

Chapter 10 — Volume Ceiling Changes
Chapter 11 — Girders and Truss Loading.

It is highly recommended to complete Parts 1 and 2 before attempting Part 3. The techniques developed in the earlier chapters provide a good basis for the complex truss repairs presented in Part 3

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

The American National Standards Institute (ANSI) defines Quality Assurance (QA) as "All of those planned or systematic actions necessary to provide adequate confidence that an item will perform satisfactorily in service". A more operational definition of quality is the one that defines as: "Fitness for Use" This points to the inescapable fact that it is the customer rather the producer or manufacturer that determines what quality is or should be.

There is a tendency to think of quality as a recent development or phenomenon. However, the basic idea of making a quality product with high degree of uniformity has been around for as long as man has made a product the idea that statistics may be instrumental in assuring the quality of manufactured products goes as far back as the advent of modern production. The widespread use of statistical methods in problems of quality control is even more recent. Many problems encountered in the manufacturing or of product and services and the associated supply chains exhibit process characteristics and as such are amenable to statistical treatment or analysis. Statistical Process/Quality control refer to three special techniques:

Process/Qualitycontrol,
Acceptance control,
Parameter design and the establishment of tolerances.

The course places emphases on the significance of process control rather than inspection as a means of reducing rework and nonconformance. Many experts agree that inspection (especially human inspection) does not add value to quality and thus is a necessary but non-value adding activity.

This first in a two-course sequence will focus on Process/Quality control with emphasis on:

Historical review of Statistical Process/Quality Control
Cost of Quality (Cost of Poor Quality)
Quality Auditing Process
The difference between Quality of Design and Quality of conformance
Differences and similarities between SQC and SPC
Total Quality Management (TQM)
The Three Gurus of TQM
Lean Six Sigma
Off-line Control and On-Line Control
Shewhart Control Charts--Interpreting Shewhart Control Charts
Process Capability Evaluation

The second course will focus on acceptance sampling and will explore some of the Military and Commercial Standards that have been developed to aid acceptance control.

349-Engineering Economics Made Easier with MS Excel

(4.7) 115 Reviews

Add Course to Cart

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

When we submit engineering proposals, we often have to overcome a number of physical limitations in order to come up with the "best" way of solving a problem.But we should also ask ourselves, "Is this the most economical way of solving the problem?"

We must be able to speak both our "technical language" and the "language of managers" (paraphrasing slightly from quality guru Joseph Juran). Managers are concerned with the bottom line and want to ensure that resources are being used in the best way possible. As engineers, we too have a similar responsibility as we protect the welfare of the public.

The field of engineering economics, formerly known as engineering economy, estimates the costs and potential savings of proposals, and then determines if the proposals make "money-sense". Because the value of money today is not the same as money in the future, we must account for the time value of money, and calculate the proposal's "net present value" based on a rate of return desired by the organization.

Back in those engineering economy days, we often would have to go to tables of numbers and look up the correct "factors" to use to calculate present values and future values. We would have to "interpolate" from the tables if we were to use an interest rate of 7.5% (because the tables skipped from 7% to 8%).It was difficult to "back into" a rate of return for a proposal, or to estimate how long it may take to recoup an investment based on a desired rate of return. (Dare I mention slide rules?)

When you take this course, you will see that MS Excel has quite a few functions that will speed through calculations involving present value, future value, annuities, rates of return, and others. Woven throughout the course are engineering, business, and personal illustrations to help you better relate to the time value of money and the rate of return.

Engineering economics is not easy. But after completing this course, you should be able to see how Excel can make it "easier".

The FREE Microsoft Excel® spreadsheet that accompanies this course will be available for download after purchase. You will need Excel version 1997 or later to open the file.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Modern computing technologies and Big data have significantly changed the discourse on data mining and data efficacy. In any system where quantities change, it is of interest to look at the effects if any, of the system variables. Indeed, there may be a relationship (in our case statistical relationship) which may be approximated by a simple mathematical relationship. At other times, the mathematical or functional relationship may be complicated. Still there may be situations where there does not seem to be meaningful relationships between the variables and yet we might want to express or relate those variables by some sort of mathematical equations.

Regression Analysis is one of the most important statistical techniques used for data mining applications. It is a statistical methodology that helps estimate the strength and direction of the relationship between two or more variables, more specifically regressor and response variables and provides detailed insight that can be applied to further improve system outcomes. The importance of regression analysis lies in its singular focus on data which means numbers and figures that ultimately define a business entity. In Regression Analyses, two types of variables are of major concern, namely the regressor or predictive variables also known as independent variables, and the response variable.

The independent or predictor variable is one that is not random but is controlled (sometimes observed such as the amount of rainfall on a plot of land when the interest is on the effect of rainfall on crop yield) during an experiment. The dependent or response variable cannot be controlled but is rather measured as an outcome of the manipulation (or observation in the case of rainfall) of the independent variable and thus is a random variable. In this course, we will focus primarily on the following elements of Regression Analyses, namely:

Parameters & Estimates
Probability Distribution of the Parameters
Covariance between two variables
Simple hypothesis tests involving parameters including one- and two-sided t and F tests
Confidence Interval for the parameters
Orthogonal Columns, Diagonal and Symmetric Matrices
Estimation of model R2, Adjusted R2, (?? or r) to assess data efficacy
Coefficient of Variation (CV)
Multicollinearity and Variance Inflation Factors

Course Description:

Vertical pumps, also called vertical suspended pumps, are common for a variety of applications. For example, the largest pump station in the world uses vertical pumps to move flood waters. Vertical well pumps supply groundwater that is treated as drinking water to a large portion of population. That tap water or bottled water nearby you right now probably started its journey with a vertical pump.

This course explains several types of vertical pumps and then walks through the pump selection process, including comparing pump curves. After completing this course, you should have the basic knowledge and skills for vertical pump selection. A spreadsheet is included for performing hydraulic calculations and plotting curves.

The following topics are covered:
•    Advantages of vertical pumps
•    Types of vertical pumps
•    Choosing the number of pumps
•    Creating a system curve

Course Description:

All engineers need a “Back to the Basics!” course and that is exactly what this course provides. The purpose of this course is to utilize the laws associated with basic direct current (DC) theory to find resistances, currents, and voltages at any given point within a circuit. This course is suitable for all engineers of any discipline. It explains the fundamentals of DC circuit theory. Whether you are a civil or mechanical engineer and are interested in learning a little about circuit theory, or if you are an electrical or computer engineer and would like to brush up on the basics, then this course is appropriate for you.

Electric circuits range from very simple circuits containing one or more resistive components and a voltage source (such as a battery and a light bulb contained in a flashlight) to very elaborate, complicated circuits (such as the microprocessor circuit card inside your mobile phone). This course provides a basic introduction to DC resistive circuits and their purpose.

The course explains the fundamental relationship between voltage, current, and resistance, known as Ohm’s Law, in an electric circuit. It explains power dissipation in a resistive element, voltage and current dividers, series and parallel circuits, and different circuit analysis techniques.

Course Description:

You will encounter digital circuits multiple times in any given day. Digital circuits have infiltrated society in ways unheard of only a few decades ago. They are everywhere and seem to be in everything. Without them we would have no microprocessors. Without microprocessors we would have no computers or smartphones or sophisticated fifth-generation fighter jets or even something as simple and convenient as a coffee maker that brews the coffee before we wake up that shuts off automatically when we forget to turn it off. Maybe we could still design a coffee maker with an analog clock with a mechanical switch that will shut off the hot plate when the clock advances forward past a mechanical set point, but the point is that these little devices (digital circuits) are commonplace and here to stay.

Digital circuits are comprised of tiny little on/off switches called transistors. The transistor is the building block of all digital circuits. This revolutionary little switching device was invented in 1947 and its creators were awarded the Nobel Prize in Physics a few years later, and rightly so. Only a few other inventions have impacted and affected our lives in so many ways.

Transistors can be organized into logic gates. The most basic gates are AND, OR and NOT. With these fundamental gates, all other gates can be built. Boolean algebra describes logic gates in symbolic form which gives a designer the ability to design a complicated logic circuit using math by forming equations. These equations are directly transformed into logic symbols and into a logic circuit. Connecting several logic gates together forms something called combinational logic. With this combinational logic, adders can be fabricated as well as encoders, decoders, multiplexers and demultiplexers. A multiplexer is a device that allows one input to be selected from several inputs. An arithmetic logic unit (ALU) is a multiplexer which is at the heart of a microprocessor's core.

This course is intended to be a review of the basics of digital logic starting with the binary numbering system, hexadecimal numbering system, logic gates, and logic circuits. This course will go over the basic logic gates, adders, decoders, encoders, multiplexers, and demultiplexers. This course has a lot of sample problems and teaches by showing examples.

Learning Objectives
