A city desires to determine the impact of a new subdivision on solid waste collection services. The subdivision will add 150 new houses. A two- person crew will collect the wastes twice a week, using 24-m^3 manually based loaded compactor trucks. The allowable container size is 014 m^3 it is estimated that there will be 3.2 persons per household and that each person will dispose of 2.5 kg of waste daily. Determine the number of containers that will be needed per household, the average container utilization factor, and the weekly labor requirement in person-days. The compaction ratio for the collection vehicle is 2.5 the average density of the solid wastes in the containers is 120 kg/m^3 the disposal site is located 25 km away and the haul time constants a and b are 0.08 h/trip and 0.015 h/km, respectively. Collection is during an 8-h day, collection is at curbside except for elderly persons (about 5 percent) who receive backyard service

Thinking Critically 10.3 >> UNPROFESSIONAL CONDUCT paper proposed a new syndrome with two conditions: chronic intestinal disease and the loss of behavioral skills that had already been acquired as part of normal child development. Out of 12 cases in the paper parents of eight of the children associated the behavioral problems with the administration of the MMR vaccine. While the paper clearly stated that no association between the MMR and the condition had been proved, the implication was there, and that was apparently enough to set off a media storm. Parents began to question the composition of the vaccination itself (specifically the thimerosal compound), and the jus- ulication for administration of all three vaccines in one dose at such a young age. Inevitably, many parents started to choose not to vaccinate their children. In Britain, 91 percent of age-eligible children were vaccinated in 1998. By 2004 that number had fallen to 80 percent which, doctors warned, was far below the 90 percent rate needed to keep the cepwater Horizon At the age of 14 months old, most children in North America and Europe receive a triple vaccination against three diseases: measles, mumps, and rubella (also known as German measles). Abbreviated as MMR, the vaccination has come under increased scrutiny over the past two decades for concerns over a potential link between MMR and autism (a neural disor- der affecting behavioral and cognitive skills). Concerned par- ents have become vocal advocates on both sides of the argu- ment. On one side, parents of autistic children believe that MMR, or specifically the preservative agent thimerosal (a mer- cury-containing chemical compound), causes significant intesti- nal problems and behavioral changes shortly after administra- tion of the vaccination. On the other side of the debate, parents are concerned that a choice not to vaccinate exposes children FatCamera/E+/Getty Images to diseases that have long been controlled in our population. This debate over a connection between MMR and autism began in earnest in 1998 after the publication in the British medical journal The Lancet of a research paper by Dr. Andrew Wakefield of the Royal Free Hospital in London. The diseases under control CHAPTER 10: MAKING IT STICK: DOING WHAT’S RIGHT IN A COMPETITIVE MARKET Despite reassurances from the Medical Research Council in Britain and the U.S. Institute of Medicine that there was no evidence of a link between MMR and autism, emotions continued to escalate.

Question 1.1: Consider the disjoint-set forest that is created after calling MAKE-SET for each vertex in Kruskal’s algorithm. Prove or disprove that the number of edges in that forest remains constant until the end of the algorithm. Question 1.2: Give a minimum order, minimum size, connected, undirected graph G=(V,E) on at least two vertices, and a nonnegative weight function w on edges for showing that the disjoint-set forest obtained when the Kruskal’s algorithm terminates is not necessarily such that all the vertices have the same parent. Question 1.3: Prove or disprove that Dijkstra’s algorithm returns a correct result in the case where G has some negative-weight edges, but no strictly negative-weight cycles. Question 1.4: Prove or disprove that when Dijkstra’s algorithm is applied from a source vertex s , then every shortest path p= with v 0 ​ =s and v k+1 ​ =x for any vertex x∈V reachable from s is such that every edge (v i ​ ,v i+1 ​ ) of p has been relaxed before edge (v j ​ ,v j+1 ​ ) of p for all 0≤i

EXPERT ANSWER 1.1The part of Kruskal’s algorithm that make a disjoint set of each vertex of a graph is given as follows:For each vertex v in graph GMake-Set(v)Make-Set(v): Make-Set(v) makes a disjoint set for vertex v such that the set contains only v in it.Thus, the above for loop creates a disjoint forest of n …
