Computer Simulation

As part of the project process, I anticipate having you

· Provide a recorded presentation for the class. This recording will be made available to all students in the class.

· Deliver a recorded presentation for the class of your final project report.  This, too, will be made available to all students in the class.

· Submit a written final project report

You should create a well-thought out proposal for a computer simulation/modeling study that you will conduct and report on, both orally and written.

The study you perform should be ambitious, unique and novel.  You may attempt something strange that no one has tried before, or you may choose to research a previous modeling effort that someone else has performed and suggest a significant enhancement of that effort.  I think that browsing through the many problems in your textbook will give you lots of ideas.  Also, general reading of newspapers and journals might give you ideas.  Recently I was reading an article, Got a minute? Global attention span is narrowing, study reveals, that was based on a modeling study.

Although you should choose something challenging and ambitious, you should also be very realistic.  We often overestimate what we’re capable of learning and exploring in a limited period of time.  It’s often useful to have a bold vision, but to also have some “off ramps” in mind in case you run into too many unanticipated problems.

Your project proposal should be submitted in PDF format and should include the following

· A brief abstract of what you want to do

· Background information about the problem and the value of a new model that allows the lay-reader to understand without having to dig deep into other literature.  At the same time, should include references to more detail.

· An initial summary of

· What information you want to produce and how you will verify and validate it

· What kinds of simplifying assumptions you think you will need to make

· What kinds of variables and parameters you think you will need to consider

· How you will implement the actual model – methods, languages

· How you will verify that the model works for your assumptions

· How you will test the model against the “real world.”

· A preliminary timeline, problems you are worried about, and some possible “alternative plans” (preferably still related to your original modeling idea) in case the problems become overwhelming (I like to call these a “Plan B”).

· A bibliography (with citations in the above text) of references you used to research the proposal

Summary of what to submit

You should submit, long before the deadline, a single PDF file that consists of

  • Your      project proposal in PDF format
  • final project report
  • A      link to your recorded YouTube presentation for the class of your final project      (again, this link will be made available to everybody in this course).

Note: Your work must be unique and no plagiarism. In such case you will be graded zero marks.

R Studio Assignment

Objective: Utilize Naïve Bayes to predict the flight delay. Given the FlightDelay.csv file, use Naïve Bayesian Analysis model to determine whether the various flights experience delay or arrive at their destination on time. We start by clicking the “install” on your R plot window (as shown below) to type and install the following packages: naivebayes, dplyr, ggplot2, and psych; one at a time. After the installation of all the packages, load them into the memory through these commands: > library (naivebayes) > library (dplyr) > install.packages(ggplot2) > library (psych) Next, we load the .csv file and check the statistical properties of the csv file as follow: > setwd(“C:/RData”) # your working directory > tumor <- read.csv(“FlightDelay.csv”) # loading the file > str(FlightDelay) # check the properties of the file . . . continue from here! Important Note: • You need to split your data into test-data (tdata) and validated-data (vdata). • Use tdata to build Naïve Bayes’ model and use vdata to predict your model. • The dependent variable (y) of the model is delay. • The independent variables are dest, origin, carrier, deptime, weather, & dayweek. • Show your conclusion.

Week 2 A

There are various instructional strategies to use when teaching a new literacy concept to students. The I Do, We Do, You Do (IWY) method is a common best practice that can be adapted during instruction. This practice includes direct instruction (I Do), guided practice (We Do), and independent practice (You Do).

Research various instructional strategies specific to concepts of print and phonemic awareness to teach new literacy concepts. Include the IWY method in your research. Describe how this strategy is implemented in grade levels K-8 and how it is effective as an instructional strategy in the classroom.

In 500-750 words, create a literacy instructional plan for how you will apply the IWY method in your future classroom when introducing new literacy concepts.

In your plan, be sure to address the following in your reflection:

  1. How the IWY model supports the introduction of new literacy concepts.
  2. How the IWY model creates and supports student engagement of typical and atypical students.
  3. How the IWY model supports differentiation to meet the diverse needs of students.
  4. Include any gaps that may be present in the IWY model.
  5. How you will use the IWY model in your future professional practice.

Support your findings with a minimum of three scholarly resources.

“Presentation Speech”

Your supervisor recently announced that you and a colleague, Bruce, will have an opportunity to meet with the company’s CEO in 2 hours and deliver a presentation on your team’s current project. Due to the short notice, Bruce believes your presentation should be an impromptu speech (delivered without notes or plan); however, you disagree with him. Under these circumstances, which type of speech do you believe you and Bruce should deliver? Choose one of the options below and share the justification you would use to persuade Bruce.

  1. Extemporaneous speech (carefully prepared and rehearsed)
  2. Manuscript speech (written out word for word and read to audience)

Designer Bag Bingo – New Choices Fundraiser

CSS. It’s a web designer’s playpen. With so many colors, type settings, layout options, and responsive possibilities, it’s easy to turn a stylesheet into a million line nightmare. However, with a few simple actions you can clean up the mess so the CSS works with you, not against you. A few weeks ago, frontend developer Julie Cameron came through our virtual Treehouse office and bestowed some wisdom we still can’t shake. So now I’m sharing it with you all!

It’s only natural. Entanglement happens.

The cascade. It’s a blessing and a curse. It’s often the case that when you change the styling of one element, other elements inadvertently get restyled. Misuse of !important makes the cascade come to a screeching halt, and leaves you with inconsistencies from one element styling to the next. As websites get bigger or more developers start working on the codebase,

the CSS tends to grow as well. Without a plan, it becomes the Wild Wild West (wickey wild, wicky wicky wild wild wild west…Will Smith isn’t gonna get you out of this one).

  • Modular – You can get to the point of building a page without writing a single line of CSS.
  • Predictable – It doesn’t matter where you put the component, it’ll behave the same and look the same. It’s easy to write the code. You have systems in place for naming it. It’s more intuitive to write.
  • Maintainable – It’s quick and easy to deal with. It won’t break other things on the site.
  • Scalable – It’s hard to break and easy to build onto.
  • Dry – It eliminates the need for copy and paste duplication in the CSS.
  • Organized – There’s a place for everything.

Separation of container from content means that objects should look the same no matter where you put them. In other words, avoid location-dependent styles. For example, if you’re styling an h2 like this…
