3. How is the purchasing and receiving function supposed to work for the Food and Beverage category – i.e., how is it designed to operate? What steps are different from the other categories? Again, a process flow map is helpful along with a specific example of something they might buy (i.e., salmon from Alaska or oranges from CA). Be sure to include the relationship with Safeway and how that works.

Find a 13-bit burst error polynomial that cannot be detected by the CRC-8 check. The burst error polynomial must have the form E(x) = x^12 + … + 1, and the terms x^k for k = 1, 2, …, 11 can have a coefficient of either 0 or 1. Here is a 13-bit burst error polynomial that can be detected: x^12 + x^8 + x^2 + x + 1. The CRC-8 generator polynomial is x^8 + x^2 + x + 1. (By a 13-bit burst error we mean that there has been a burst of energy that causes noise on the communication channel during the span of 13 bits. For example, the energy may drive the voltage to a high value for all 13 bits. Some of those bits might have been 1’s (and represented by the high voltage), so the energy does not cause those bits to be in error. So, assume the first and thirteenth bits are incorrect, and the bits in between those two end points may or may not be in error.)

1. You are the director of operations of a large airport. Discuss the above statement showing how far it is reflected in your day to day work. 2. The Information Super-highway is widely used in modern airports. Discuss how the Information Super-highway is useful in the following domains: a) Communication b) Security

We want to develop a sales system for a mobile shop. The system should keep information about the mobile phones available at the shop. the system should allow the user the ADD new mobile phones, one at a time, along with their features. The system should also allow to search mobile phones , update their information, and delete them (one by one). Try to provide different criteria for search. When the system starts, it should load the information about the mobile phones forma file. if the file doesn't exist, the system should create the file. The system should provide a (console based) menu to interact with it. The system not use any arrays and all the changes should be reflected in the file.

Describe the three main types of referential actions (cascade, restrict, set null). How do you use these in your work?

I have a problem with the code for my project. I need the two clients to be able to receive the messages but the code I have done only the server receives the messages. I need the clients to be able to communicate with each other directly not throught the server.

The requirements of this "local chat" program must meet are:

1. The chat is performed between 2 clients and a server.

2. The server will first start up and choose a port number. Then the server prints out its IP address and port number.

3. The client then will start up and create a socket based on the information provided by the server.

4. Now the client and the server can chat with each other by sending messages over the network.

5. The client/server MUST be able to communicate with each other in a continuous manner. (e.g. One side can send multiple messages without any replies from the other side)

6. There is no requirement on what language you use to implement this project, but your program should call upon the socket API for UDP to realize the functionality.

7. You should demonstrate your project using two machines (one for the client and one for the server. Pick your virtual machine as the client to communicate with your actual machine, which is server in our project).

8. You need to open at least 2 cmd window in your virtual machine to demonstrate multiple machine communicate with your server machine (actual machine)

Considering Google Maps as a graph, list four possible weights that can be associated with edges of the graph.

​B) McDonald’s has been promoting that it is serving its quarter pounder using fresh beef​ (after 4 decades of using frozen​ patties). This was done to bring back diners who have been lost to​ competitors; however franchise owners had expressed concerns about food​ safety, costs, storage . . . Examine this change from an operations management perspective explaining the types of issues operations managers likely had to address for it to be successful​ – and why you think it may​ (or may​ not) be worth it.

What encryption/decryption and hashing algorithms are used in PGP and how are they used?

write at least 500 words of your explanation and reference.

The demand for a good (X) is estimated to be Q x = 2,200 - 2 Px + 4Py - .1M + .5A x , where A x represents the amount of advertising spent on X and the other variables have their usual interpretations. Suppose the price of good X is $550, good Y sells for $40, the company utilizes 3,000 units of advertising, and consumer income is $20,000.

a. Calculate the own price elasticity of demand at these values of prices, income, and advertising. Is demand elastic, inelastic, or unitary elastic?

b. Calculate the cross price elasticity of demand at these values of prices, income, and advertising. Is demand elastic, inelastic, or unitary elastic?

c. Calculate the income elasticity of demand at these values of prices, income, and advertising. Is demand elastic, inelastic, or unitary elastic?
