Check the video and answer the questions.

#1 John Cage Sonatas and “Interludes for Prepared Piano, Sonata II” (1946-48)
This piece is written for piano, but certainly doesn’t sound like the traditional tone color of the piano.  Describe the tone colors that are generated by this “prepared piano.”  What is a prepared piano? How are some of the particular tone colors that you hear produced by this acoustic instrument?  What influenced Cage to invent “the prepared piano”?https://www.youtube.com/watch?v=oL_UdQf704A You can watch a short video on how to prepare a piano here: https://www.youtube.com/watch?v=myXAUEuECqQ

#2  Edgard Varese “Poème électronique” (Electronic Poem: 1958)
The first stage of music produced electronically in the twentieth-century was called “musique concrete.”  Composers recorded sounds onto audio tape, and then manipulated them in the studio to produce a fixed performance of the piece.  Varese’s Poem electronique is perhaps one of the most famous of these works.  read about it in your textbook before you listen.  Try to put yourself back in 1958 and think about the technology that was available at that time.  Listen carefully to try to discern some of the raw sound material.  How do you think this piece was received in 1958? https://www.youtube.com/watch?v=qTMSllIv2lw

#3  John Adams “Short Ride on a Fast Machine” (1986)
John Adams is most often referred to a “postminimalist” composer.  Listen to his “Short Ride in a Fast Machine” and discuss why this piece could be described as “minimalist.”  Does this piece aptly portray its title?  What specific types of musical techniques does he use in this piece to create the perpetual motion? https://www.youtube.com/watch?v=5LoUm_r7It8

#4  Kaija Saariaho “L’amour de loin” (Love from Afar: 2000)
Saariaho’s career has produced music that has used techniques of live electronics, mixed media (music, text, tape, electronics, dance, video). What is the impact of the mix of traditional instruments and electronic sounds?   How does this opera compare with the others we have studied in class, i.e. Mozart, Verdi, Wagner? https://www.youtube.com/watch?v=DKBm9mKWJVU

#5 Tania Leon “Inura” (2009)
Using the vocabulary you have learned so far in the course, describe the basic characteristics of this piece.  Explain how Leòn utilizes call and response during this movement. Discuss the role of the percussion during this movement. Be specific. https://www.youtube.com/watch?v=5WCsr4qeij4

Objective

You are to implement a simple database using a sorted file of fixed length records. The data that you are to use for testing is in file: Parks.csv Windows compatible (cr lf). This data contains the visitation records for the US National Parks from 1904 to 2016.. The goal of this assignment is to understand and practice using file management techniques to implement a database system. Your file-based database needs to handle overflow by writing records to an overflow file that contains unsorted records.

First, create a file of fixed length records from the data provided interleaved with blank records. Your file should create space for insertions by writing one blank record between each real record. Meta-information should be stored in a non-fixed length way in a separate configuration file, e.g., “Parks.config”. The config file must also store useful data like the names of the fields (for display), the number of records, and anything else you would want to add.

So, the initial file will have 764 records, half of which are blank. When a record is inserted, the file is searched (using binary search) to find the correct location. If there is a blank record where the new record needs to go, then the blank record is simply overwritten. However, if there is no empty record available in the correct location, the original file should be re-written with new blanks inserted, including after the new record. For example, if we do 3 inserts into blank records, we would now have 385 real records in our file of 764 total records. If the next insert fails, we would create a new file with 770 total records in it (the 385 real records, each with one blank record after it).

You must not read the whole data file into memory at a time

Program Description

Create a program which offers the user the following menu of operations:

1) Create new database
2) Open database
3) Close database
4) Display record
5) Update record
6) Create report
7) Add record
8) Delete record
9) Quit

WEEK 7 – DISCUSSION

In no less than 250 words, describe the difference between a fat AP and a thin AP. What is needed to deploy a thin AP? Are there any security considerations to think about between the 2 different APs?

Week 7 – Discussion

Have you or someone you know ever received a chain letter, phishing message, or some other fraudulent message via email? If so, please share this experience. Explain what type of message it was and what you did to get rid of it.(250 words)

Week 7 Assignment

• 7.1 What is the basic building block of an 802.11 WLAN?
• 7.2 Define an extended service set.
• 7.3 List and briefly define IEEE 802.11 services.
• 7.4 Is a distribution system a wireless network?
• 7.5 How is the concept of an association related to that of mobility?
• 7.6 What security areas are addressed by IEEE 802.11i?
• 7.7 Briefly describe the five IEEE 802.11i phases of operation.
• 7.8 What is the difference between TKIP and CCMP?

Lists. Trace the following c++ program showing all output in the order that it appears on the output device (presumably the screen). If anything happens that makes it impossible to accomplish an operation or the results of doing so are unpredictable, describe what happens and abort at that point.

For this program assume that the following functions (methods) are fully defined and implemnted in the appropriate header and implementation files for the List class.

– construct that creates an empty list

– empty that returns true if the list is empty, false otherwise

– insert (a,b) that inserts an integer a into the list at position b

– erase(a) that removes the integer at position a in the list

– overloading the output operator << to enable it to display all elements of a list in sequence so cout<

– overloading the assignment operator so assigning one list to another creates a deep copy of the list.

CODE BELOW

#include
using namespace std;
#include “List.h”
int main(void)
{ List sheldon_cooper;
List leonard_hofstadter;
int i, j;
cout<<"Program begins, sheldon and leonard constructed"< if (sheldon_cooper.empty())
cout<<"His friend is Raj Koothrappali"< else
cout<<"His friend is Penny"< for (i=4;i<=8;i++)
{cout<<"Inserting "< sheldon_cooper.insert(i*2-3,i-4);
cout<<" List is now ";
cout< }
leonard_hofstadter=sheldon_cooper;
j=3;
cout<<"removing position "< sheldon_cooper.erase(j);
cout< j=2;
leonard_hofstadter.insert(54,j);
cout<<"leonard is now ";
cout< cout<<"program ends, buzz off ";
return 0;
}
