etically engineered killer hounds patrolling the grounds of the FORTRESS OF MISERY. Fortunately, Captain Proton has a piece of bone to whittle into a flute (assume this is a tube open at both ends). A sound with a frequency of 23015 Hz will disable the Killer hounds. Assuming a speed of sound of 334 m/s, how long must the flute be so that its fundamental frequency will disable the Killer Hounds? (3 points) 2. The delivery entrance of the FORTRESS OF MISERY is guarded by a Destructo-Bot that is programmed not to respond to any sound less than 50 dB in relative intensity. Captain Proton will set off a small explosion 10.0 m from the Bot. How much power must the explosion’s sound carry in order to exceed 50 dB at the Bot’s position. Assume that I0 is 1.0*10-12¬¬ W/m¬2. Surface area of a sphere = 4πr2. (5 points) that is due tonight

ution, regression, decision trees Past paper has 5 questions (attached), we will have 4. Complexity of questions will be reduced slightly for decision trees and regression. Visualisation question – written in word file or hand-written and scanned or photographed. Normal distribution: Sketch using online normal distribution visualisation applet (add notes around this to discuss if necessary) or sketch by hand and scan or photograph. For mathematical workings, use formulae sheet, copy, paste and adapt, or scan / photograph your workings and upload. Decision tree – use Office smart shapes, or sketch by hand and scan or photograph. If formulae are required, then use formula sheet, copy, paste and adapt. Regression – written in word file or hand-written and scanned or photographed. MCDA – written in word file or hand-written and scanned or photographed. Remember if they appear, decision trees and regression will be a little less technical than they have been in the past. (To allow more of a buffer with regards to time available to complete and upload). Visualisation and MCDA questions will be more general (strengths and weaknesses, key messages, make some recommendations). Exam questions will be set so as to minimise practical and logistical difficulties in uploading answers.

eation of several BST functions * We have to use Valgrind * We have to create a memory struct that provides a compare function for insertion * The above needs to contain two fields of unsigned int, representing memory address and size int memory_addr_cmp(const void* x, const void* y){ //TODO return 0; } By the instructions: "This function takes two arguments, const void* x and const void* y, you will need to cast both of them to type "memory*", and make comparisons. If x is less than y, return -1. If x is greater than y, return 1. If they are equal, return 0;" Also per the instructions, concerning the BST functions "Note, in particular, that there are two separate structus - the node struct that describes information for a single node in the tree, and a bst struct, that holds the root pointer and a function pointer to the comparison function being used for this tree. When you first create the tree, you pass in the comparison function, and this will be used for all functions that need it thereafter. Therefore, after that, you don't need to specify the comparison function to bst-level functions. The stored function pointer is then passed to the node-level functions." So then we have to create allocation and initialization functions for both the BST and one for the node. * nod_insert, BST_insert then inorder_traversal
