you are asked to write a formal essay (1500
words) on one of the following topics. As with your first assignment,
there are no formulas for how to go about tackling each of these
concepts. That is, you are free to find your own way, as long as you can
demonstrate a real engagement with the course materials and with the
issues we have been discussing in lectures and seminar.
1. “..your ancestor did not think of time as absolute and uniform” (Borges,
“Garden of Forking Paths” 100, Coursepack 69)
Write a comparative essay on the topic of time using at least two
of the readings (or the film) we have discussed in the “Time and
Space” section of the course.

Microcontrollers

Project: SPI controller using DAC slave and PIC slave to change the speed of two motors, read the speed of one of these motors and control 8 actuators

Students set up SPI link with serial DAC SPI Slave and PIC16f877a SPI master.

A motor controller uses a driver circuit that amplifies an analogue signal sent from a microcontroller though a SPI enabled slave DAC chip and an SPI enabled slave PIC16f877a.

The master microcontroller is in idle mode and
If the master receives a signal from a PC via its USART indicating that motor 1 should undergo a change in speed, the master moves into change speed of motor 1 mode, the next signal the master receives from the USART indicates the speed the master will set the SPI DAC at (which controls the speed of motor 1), the master then enters its idle mode again and waits to receive a signal from the USART.
If the master receives a signal from a PC via its USART indicating that motor 2 should undergo a change in speed, the master moves into change speed of motor 2 mode, the next signal the master receives from the USART indicates the speed the master will set the SPI DAC at (which controls the speed of motor 2), the master then enters its idle mode again and waits to receive a signal from the USART.
If the master receives a signal from a PC via its USART indicating that the master should read the speed of motor 1, the master then enables the PIC16f877a slave and sends a signal to the slave indicating it wants into read speed of motor 1, the PIC16f877a slave performs an ADC and loads the SPI buffer with the result of the ADC. When the masters sends a second SPI signal to the slave, the slaves ADC result is transferred into the master. The master should display the speed of motor 1 by sending a signal to the PC using the USART notifying the user of the speed of motor 1.
If the master receives a signal from a PC via its USART indicating that the master should write to 8 linear actuators connected to pins on port D (8 LEDs connected to port D, the master then enables the PIC16f877a slave and sends a signal to the slave indicating that it wants to change the status of the 8 actuators in the system. The master then performs a second write to the PIC16f877a slave and sends a value for the status of 8 actuators in the system; the PIC16f877a slave uses the second value from the master and writes this value to port D. The slave should also place the value it has written to port D in its SSPBUF and when the master performs a third write to the slave SPI, the value in the slaves SSPBUF should be transferred back to the master. The master should display this value on the PC using the USART notifying the user of the status of 8 sensors connected to port D.

Virtualization and Cloud Computing

Write a 5-7 page paper about virtualization. This paper should demonstrate well-thought out, well-research ideas and information. The information should flow well together, and make sense! A helpful suggestion is to have someone to read it who knows absolutely nothing about the topic. If they understand it, you have written a good paper.

There are three parts to this research:

Define virtualization in simple terms and explain why it is an important technology. A couple of paragraphs will be fine.

Include what is meant by cloud computing and how it relates to virtualization. Again, a couple of paragraphs will be fine.

Finally, compare desktop virtualization solutions offered by each of the three top virtualization companies: VMWare, Citrix and Hyper-V. Include a discussion about advantages and disadvantages of each product. Be sure to limit this research to desktop virtualization!

Phonemes and the International Phonetic Alphabet

Before you begin this assignment it will be necessary to have read the section of the chapter covering language (Chapter Nine) concerning Descriptive Linguistics.  You will also want to consult your notes from the lecture on Descriptive Linguistics, as I will cover all of the information necessary to successfully complete this assignment.  If you missed the class during which I covered this information you will need to borrow the notes of a friend or come see me during office hours.

 

Part One:  Phonemes and the International Phonetic Alphabet

the first portion of the assignment you will need to translate the first 20 words of your paragraph into the symbols of the International Phonetic Alphabet.  You may need to do a bit of research to find the symbols you need to express this.  This link (http://en.wikipedia.org/wiki/International_Phonetic_Alphabet_chart_for_English_dialects) will take you to the Wikipedea page for the IPA symbols used by the various English dialects.  To assist you in entering this for submission you can use the following website to type your answers: http://ipa.typeit.org/full/.  Then simply paste your results into a .doc, .docx, or .rtf file.  You should also include the text you are translating so we can compare the two easily when we grade your assignment.

 

Example for part one:  The two sentences below have been translated into IPA so that you can see how your own efforts should look.

 

The text to be translated:      My name is Christian Petersen.  I am a college instructor.

After translation:                  maɪ neɪm ɪz kɹɪstt͡ʃʌn pʰitʰɹsʌɴ. aɪ æm eɪ kʰɑlɪd͡ʒ ɪɴstɹʌktoɹ.

Part Two: Morphemes, Bound & Free

For the second part of the assignment, you will need to identify the morphemes for the first 40 words of the first complete paragraph on the page you were assigned. Keep in mind that free morphemes must be related to the original word.  For example the word “firetruck” consists of two free morphemes “fire” and “truck,” but “some” is a single morpheme despite the fact that “so” and “me” could be considered individual free morphemes.  This is because the meaning of “some” is not based on the morphemes “so” and “me.”  You should also include the text you are translating so we can compare the two easily when we grade your assignment.

 

Example for Part Two:  Here is an example to help you format your assignment.

The capture would be performed robotically, and the relocated asteroid would become a destination for astronauts to explore—and, possibly, for space entrepreneurs to mine.

TheF captureF wouldF beF performF/edB robotF/icB/allyB, andF theF reB/locateF/dB asteroidF wouldF becomeF aF destinationF forF astronautF/sB toF exploreF—andF, possiblyF, forF spaceF entrepreneurF/sB toF mineF.

Forged insurance contracts sold to deceased by ins...

An insurance agent approaches a businessman and proposes to sell him a life insurance policy. Businessman agrees and consents to provide his financial information and a medical check up. Both medical check up and financial statements are provided to the insurance representative who comes back after about a month with an insurance contract and is paid the first premium. The insured dies soon after in a car accident. The insurance company refuses to pay ” claiming that the insurance contract had actually not been approved and the one given to the client was a forged contract drawn up by their representative”. How many cases can you provide as precedence to make the judge rule for the claimants.
