Question 6 A wastewater sample was collected after screening and grit removal step from Waterloo WWTP. The sample was analyzed in the lab. The sample was found to have the following properties: Total COD 350 mg/L Soluble COD 200 mg/L BOD, 220 mg/L VSS/TSS ratio is 0.7 Removal efficiency of the primary clarifier in the WWTP is 60% for both VSS (both nbVSS and bVSS) and FSS. Assume that biological activity is restricted in primary clarifier, and all soluble compounds pass through. The effluent from primary clarifier is further treated in active sludge Solution To calculate rb COD we use formula sCOD = rbCOD + nbsCOD Where sCOD is soluble COD = 200mg/L, so rb COD 200 = rbCOD + 50; rbCOD = 150 mg/L Now for calculating sb COD we use formula bCOD = rbCOD + sbCOD However, we don’t have bCOD [Biodegradable COD], to calculate that we use bCOD (1.7) of (BOD) bCOD = 1.6 x 220 = 352 mg/L Now bCOD = rbCOD + sbCOD 352 = 150 +sbCOD; sbCOD = 352-150 = 198 mg/L.

Herpes viruses are transmitted to humans by: A. Birds B. Fleas C. Rodents D.Rodents D. Carnivories E. None Solution 1. The correct option is d because the baby becomes cyanotic is mainly because of the insufficient supply of oxygen which is due to the impaired cardiovascular supply of the lungs. 2. the correct option is a because the blood plasma is responsible for the pH maintenance and works with lungs and kidney to maintain the pH of the body fluids by maintaining the acid and base ratio. 3. The correct option is a because the low levels of chloride level suggest that the body is losing the ions away during vomiting along wth the food particles. 4. The correct option is b because the level of enzymes that are released by the invading cells for the destruction of the proteins of the extracellular matrix which separates the cancer cells and the adjoining tissue. The level of degrading enzymes is responsible for the proliferation and escape of the cancer cell into the surrounding tissue. 5. The option is b killer t cells. 6.

Briefly describe the four categories of transit system characteristics. c. Briefly describe the various transit modes of transportation End of Problem #4 Problemi #5 (20 points) Transportation Engineering is a multidisciplinary area of study. It is a profession that carries distinct societal responsibilities. What would a comprehensive training include? Provide examples of each training tem a) b) c) d) Explain the difference between direct elasticity and cross elasticity. Give one example of each What does CBD mean? Give an example of a CBD A transportation network having the following characteristics Travel time (minutes) between nodes Nodes From 10 10 10 0 16 12 Each node represents an activity center, and each link represents travel time in minutes. Draw a link/node diagrams for the travel times and distances, if the average travel speed on all links is 30 miles per hour End of Problem #5 Solution 4. (a). There are 2 ways in general to model the dwell time at a particular stop which depends on whether the boarding and alighting processes are sequential or simultaneous. Assuming in the question given that sequential boarding and alighting takes place since only one front door is available for flow of passengers: Dw = a * A + b*B + td ; where A and B are the number of boarding and alighting passengers respectively a and b are time intervals for boarding and alighting per passenger. td is the average clearance time for opening and closing the doors. Here a= 3 sec, b=1.8sec Therefore, at Stop 1: Dw1 = 3*20 + 1.8*0 + 5 = 65 sec Stop 2: Dw2 = 3*5 + 1.8*3 + 5 = 25.4 sec Stop 3: Dw3 = 3*7 + 1.8*5 + 5 = 35 sec Stop 4: Dw4 = 3*3 + 1.8*6 + 5 = 24.8 sec Stop 5: Dw5 = 3*4 + 1.8*8 + 5 = 31.4 sec Stop 6: Dw6 = 3*2 + 1.8*7 + 5 = 23.6 sec Stop 7: Dw7 = 3*0 + 1.8*12 + 5 = 26.6 sec Total dwell time= 231.8 seconds (b). Transit system characteristics can be classified into four main categories: i. System performance elements: Contains entire set of physical performance related elements which decides the raw efficiency of the central system employed as the primary functional core unit of the transit model. This includes Service frequency, operating speed, reliability and safety measures and line and productive capacities. ii. Level of Service (LOS) is an important service parameter that affects the users drastically due to differential change in its delivery. It is a simple basic most powerful characteristic that can attract the users or provide bad experiences to them if miniscule error occurs in provider’s implementation. The factors that affect LOS are performance.

As your reward for saving the Kingdom of Bigfunnia from the evil monster “Exponential Asymptotic,” the king has given you the opportunity to earn a big reward. Behind the castle there is a maze, and along each corridor of the maze there is a bag of gold coins. The amount of gold in each bag varies. You will be given the opportunity to walk through the maze, picking up bags of gold. You may enter only through the door marked “ENTER” and exit through the door marked “EXIT.” (These are distinct doors.) While in the maze you may not retrace your steps. Each corridor of the maze has an arrow painted on the wall. You may only go down the corridor in the direction of the arrow. There is no way to traverse a “loop” in the maze. You will receive a map of the maze, including the amount of gold in and the direction of each corridor. Describe and analyze an efficient algorithm to help you pick up the most gold in this maze while traversing a path from the start to the finish.

Answer the following questions about molecule movement across a membrane. a. How is osmosis similar to simple diffusion of CO_2 across a membrane? How is it different? If an aquaporin is involved, how does this change your answer? b. Compare and contrast carrier proteins and channel proteins. Include information about both structure and mechanism of transport. c. Compare and contrast indirect and direct active transport. Give a specific example for each type of transport. Solution 5a: Osmosis is the movement of water molecules down the concentration gradiant through a semipermeable membrane. Both osmosis and simple diffusion of CO2 across a membrane occur down the concentration gradiant and are passive transport. However, osmosis transports hydrophilic water molecules while simple diffusion transports hydrophobic non polar CO2 molecules. If an aquaporin is involved, the proces would be called as facililated diffusion which refers to transport of polar, charged, hydrophilic molecules down the concentration gradiant with the help of membrane transport proteins. 5b: Carrier proteins are the transporter proteins that are actually the integral membrane proteins serving in transport of ions across the membrane. These proteins have ion binding sites and exhibit changes in shape to transport the ions. Channel proteins are the integral membrane proteins that form the hydrophilic channels for transport of polar, charged and hydrophilic substances across the membrane. They do not undergo the shape change. 5c: Direct active transport couples the exergonic chemical reaction for increasing the solute/ion concentration on one side of the membrane. The indirect active transport includes coupling of favorable downhill movement of one solute to the unfavorable uphill movement of other substance. For ex: sodium potassium pump couples ATP hydrolysis with uphill movement of sodium (direct active transport). Downhill movement of sodium coupled with uphill movement of glucose (indirect active transport)..

Hosts A through J have been connected to a switch for some time, with Host A on port 1, Host B on port 2, and so on. A user moves his system and connects Host A to interface 12. Immediately after the connection, Host A sends a unicast message to Host B. Which of the following are true? A. When the frame enters the switch, it is flooded to all interfaces. B. When the frame enters the switch, it is sent directly to interface 2, and no other. C. After this unicast message is sent, frames addressed to Host A will continue to be sent to interface 1. D. After this unicast message is sent, frames addressed to Host A will be sent to interface 12. Solution B and D are correct. Moving Host A to a different port would not affect the delivery of frames with a destination MAC for Host B—still on port 2. As the first message from Host A is received, the CAM table will update to the new port (12). A and C are incorrect. A is incorrect because only three types of frames are flooded by switches: broadcast, multicast, and frames without a matching entry in the CAM table. Since Host B is still in the CAM table, the message would be delivered appropriately. C is incorrect because the CAM table is updated to Host A’s new port number immediately after the frame enters the switch..

I have code written for this problem but I am struggling finishing it so I am hoping to see it done in a perhaps different way than how I approached it. Here is the question: Write a program which implements Huffman Encoding assuming a code alphabet of Z2, ie, binary codewords. Start with a class called HuffmanNode.java, which contains the required fields S, P, C, L, as well as a left and a right child HuffmanNode. The algorithm should proceed as follows: First, the user selects a text file, which is read into your program. Each line of the text file will have a symbol, sk S, and a probability, pk P. Each line should be written to a distinct HuffmanNode, (leaving Ck and lk blank for later). The newly semi-filled HuffmanNodes should be added, in increasing order of pk into a HuffmanNode list: an ArrayList of HuffmanNodes. Then the Huffman tree is created by following the Huffman Algorithm. After the tree is created, the tree is traversed recursively in order that the codewords and lengths may be added to the HuffmanNodes. Finally, print your symbols and codes to the screen or to a file for verification. Also, you should traverse your Huffman Tree in order to compute the average codeword length of your new code, (the ACWL(C)). Solution // C program for Huffman Coding #include #include // This constant can be avoided by explicitly calculating height of Huffman Tree #define MAX_TREE_HT 100 // A Huffman tree node struct MinHeapNode { char data; // One of the input characters unsigned freq; // Frequency of the character struct MinHeapNode *left, *right; // Left and right child of this node }; // A Min Heap: Collection of min heap (or Hufmman tree) nodes struct MinHeap { unsigned size; // Current size of min heap unsigned capacity; // capacity of min heap struct MinHeapNode **array; // Attay of minheap node pointers }; // A utility function allocate a new min heap node with given character // and frequency of the character struct MinHeapNode* newNode(char data, unsigned freq) { struct MinHeapNode* temp = (struct MinHeapNode*) malloc(sizeof(struct MinHeapNode)); temp->left = temp->right = NULL; temp->data = data; temp->freq = freq; return temp; } // A utility function to create a min heap of given capacity struct MinHeap* createMinHeap(unsigned capacity) { struct MinHeap* minHeap = (struct MinHeap*) malloc(sizeof(struct MinHeap)); minHeap->size = 0; // current size is 0 minHeap->capacity = capacity; minHeap->array = (struct MinHeapNode**)malloc(minHeap->capacity * sizeof(struct MinHeapNode*)); return minHeap; } // A utility function to swap two min heap nodes void swapMinHeapNode(struct MinHeapNode** a, struct MinHeapNode** b) { struct MinHeapNode* t = *a; *a = *b; *b = t; } // The standard minHeapify function. void minHeapify(struct MinHeap* minHeap, int idx) { int smallest = idx; int left = 2 * idx + 1; int right = 2 * idx + 2; if (left < minHeap->size && minHeap->array[left]->freq < minHeap->array[smallest]->freq) smallest = left; if (right < minH.

A researcher is studying the determinants of state-financed welfare programs in the United States such as unemployment compensation and aid to dependent children. She feels that because states in which average income is high have larger tax revenues, they are better to able to afford welfare programs. Therefore, she hypothesizes that the higher the average income in a state, the more welfare programs the state legislature will have adopted. She obtains data permitting to the average income of the residents of each state (coded low; high) and the number of welfare programs passed by each state legislature (coded; many). These data tied the following cross- tabulation. Average Income Number of Welfare Programs Low High Few 9 16 Many 11 14 In reporting her results of her study, the researcher comments about the above cross-tabulation: \"Because more states in which the average income is high (14) have passed many welfare programs that have states in which the average income is low (11), this table provides support for the hypothesis. High average income in a state tends to lead to the passage of welfare programs.\" Do you agree with the conclusion reached by this researcher? Present evidence to support your answer. Solution here we go for chi-squre test for independency of attributes Ho: there is no relationship between average income and welfare program Ha: there is dependency between average income and welfare program Average Income Number of Welfare Programs Low High total Few 9 16 25 Many 11 14 25 20 30 50 E(9)=25x20/50, E(16)=25x30/50,E(11)=20x25/50, E(14)=30x25/50 chi-square statistic=(O-E)2/E with df=1 here O are 9,16,11,14 and E are 10,15,10,15 chi-squre=0.3333 P=0.5637 since P is more than 0.05 so we say that at 5% level of significance we reject alternative hypothesis and accept null hypothesis that there is no relationship between average income and welfare program. conclusion:High average income in a state does not tend to lead to the passage of welfare programs.\".

How do government policies and/or regulations factor into changes in economic activity on both a domestic and global scale? Give a specific example of a policy or regulation that has helped economic activity. Give a specific example of a policy or regulation that has hindered economic activity. If you were an economist who was tasked with evaluating this policy or regulation, what are some ideas you would suggest for changing it in a way that would achieve the same goal but not hinder economic activity? Finally, state whether or not you enjoy these types of evaluations and if you would consider these types of responsibilities in a future career. Solution Monetary policy is by far the most powerful weapon in the government’s arsenal. Unfortunately, it is also the most imprecise. The government can do some fine control with tax policy to move capital between investments by granting favorable tax status On the whole, governments tend to go for large, sweeping changes by altering the monetary landscape. Governments are the only entities that can legally create their respective currencies. Interest rates are another popular weapon, even though they are often used to counteract inflation. They can spur the economy separately from inflation. Pumping in money feels good for a while, especially for investors who see corporate profits and share prices shooting up, but the long-term impact is an erosion of value across the board. Savings are worth less, punishing savers and bond buyers Government programs provide valuable \"public goods\" such as education and infrastructure. Inreases in government spending can bolster economic growth by putting money into people\'s pockets. I believe the policy of QE (quantiative easing) during times of recession to bring back a shattered economy in place. An automatic reversal will never happen, and it is imperative on the part of government is follow such prudent measures. I would consider these types of responsibilites in a long-term perspective. *****.
