Part A [10 points] Create a class named Case that represents a small bookbag/handbag type object. It should contain: Fields to represent the owner’s name and color of the Case. This class will be extended so use protected as the access modifier. A constructor with 2 parameters – that sets both the owner’s name and the color. Two accessor methods, one for each property. (getOwnerName, getColor) A main method that creates an instance of this class with the owner’s name set to ‘Joy’ and color set to ‘Green’. Add a statement to your main method that prints this object. Run your main method again. Is this what you think should be displayed when this object is printed? Override the toString() method and return a string. For your Case object created in the previous step the string should be: "Case Owner : Joy , Color : Green"

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
