This is a modeling problem in Interger programming. We have a problem that dealt with different cities—some city that have factories that made an item and others that didn’t have factories. There are specific capacities on each of the routes between cities (“number of trains”). Each city had a demand of the items that had to be fulfilled. Items could be shipped to cities that are not adjacent as well (with a connection through another city/cities). We had to find a way fulfill these constraints that minimized the cost of transportation. Solution In order to approach these problems with no data, there will be demand of different items Let us suppose there are 3 items I1,I2,I3 and demands of which are D1,D2 and D3 Then the demands of all the three items must be fulfilled, items can be shipped from other cities i.e. D1 can send an item through D3, if there exists a path from D1 to D3 by connecting over other cities Please provide the constraints.

There is a surge of mergers and acquisitions among television networks, entertainment, and internet-related companies since 2010. Some have been completed, some have been stopped by regulators, and others are still in progress. How are these different from the AOL-Time Warner merger of the year 2000? Are the recent mergers and acquisitions likely to be successful? Why or why not? Solution A decade ago, America Online merged with Time Warner in a deal valued at a stunning $350 billion. It was then, and is now, the largest merger in American business history. After gaining Federal Trade Commission approval, the deal had its skeptics. AOL was the majority shareholder, and for the financials to add up, AOL would have to continue making bundles of money in advertising revenue. Before the ink was even dry on the deal, the dot-com bubble had burst, Internet stocks plummeted, and the bottom fell out of the online advertising market. To make matters worse, increased availability of high-speed Internet access cut deeply into AOL\'s dial-up revenue The merger proved poisonous for both companies and downright deadly for investors. About $100 billion in stock value was wiped out . In 2009, Time Warner spun AOL off as its own company. Today, the AOL-Time Warner marriage is the standard business school case study for the worst merger ever. It was an odd merger, where both companies retained their independence. In fact, Time Warner appears to have retained more power than AOL, even though technically, AOL bought Time Warner. There was a great potential to a merger - just imagine having the largest ISP (dial-up) with millions of internet accounts merging with one of the largest cable network providers with millions of homes connected to coaxial and then fiber networks. Yet, they could not make it work. The rumor has it that the executives of both companies after the merger (yet, again - they were never one company) went to negotiate their consumer offering, specifically, AOL over Time Warner boradband network. Nobody wanted to give up any revenue. The outcome? If you want AOL over broadband, you can pay the current price for Time Warner internet (around $45/mo back then) plus the standard AOL fee (around $20/mo). Needless to say, it was not a popular offer. AOL slowly died. Time Warner spun it off. NOW A days mergers and acquistions are going smoothly Here’s a list of examples of good mergers and acquisitions transactions: Human factors almost always have a significant impact on both a deal’s success and the amount of additional cost and effort required to recover when they were not sufficiently considered. The five human factors below differentiate successful deals: Managing human factors increases the likelihood of value being realized: people are complicated, and building a team that has the capacity and inclination to attend to them is a differentiator in an industry where many still focus on the technical elements of the deal..

Technology is advancing at an alarming rate. We now have more methods of interaction than ever before: phone, text, instant messenger, GPS, Skype, etc. Businesses today must be connected at multiple levels via multiple media in order to be competitive. Ponder and develop a strategy for future forensic applications in an increasingly digitalized and connected world. Discuss the challenges that these new media and technologies present to the forensic analyst and begin to frame some solutions. Solution Computer forensics is the practice of collecting, analysing and reporting on digital data in a way that is legally admissible. It can be used in the detection and prevention of crime and in any dispute where evidence is stored digitally. Computer forensics follows a similar process to other forensic disciplines, and faces similar issues. The phrase “digital forensics” invokes an image of law enforcement officers conducting criminal investigations. The breadth of digital forensics practices goes far beyond this narrow definition. Civil cases use forensic analysis. Large corporations and organizations use their own forensics groups to investigate internal issues, compliance, and insider threats that are rarely publicly released. Governments have forensic resources that are applied in many areas, such as military intelligence. Forensic Applications of New Analytical Technologies Multiply hyphenated techniques, such as gas chromatography/mass spectrometry with retention time locking (GC/MS/RTL), liquid chromatography/time-of-flight mass spectrometry (LC/MS/TOF), microfluidic-based capillary electrophoretic analysis of mitochondrial DNA (mtDNA), and laser ablation inductively coupled plasma mass spectrometry (LA/ICP/MS), are able to uncover forensically germane information by providing unprecedented levels of analytical selectivity and sensitivity, extracting genetic signatures from previously overlooked biological sources, and sequentially microdeconstructing samples so as to map the spatial variation and concentration of elemental constituents. These new ranges of information and rich data sets can contribute facts crucial to the reconstruction of events and thereby increase the probability of an accurate finding in the matters under investigation..

Suppose a mutant fruit fly with blue eyes was recently discovered. It is later determined that the blue eye trait is recessive to the wild-type red eye trait. What is the most common way to represent the mutant and wild-type alleles? Choices are Mutant: Bl, bl Wild-type: Bl+ , re, bl+, or wt Solution A gene is a discrete unit of DNA that codes for a particular trait (e.g., eye color). Alternate forms of a gene (e.g., brown, blue, or white eyes) are called alleles and the allele’s physical location on a chromosome is its locus (pl... loci). The following are loci of various fruit fly traits: TABLE 26.Loci of some fruit fly traits. Traits beginning with a capital letter denote the allele is dominant. yellow body 0.0 Curly wings 6.1 purple eyes 54.5 HWrinkled wings 46.0 eyeless 0.2 Diploid organisms possessing the same allele at the same locus on each homologue are homozygous for that trait; whereas, those having different alleles at a particular locus are heterozygous. For genetics studies, it is important to know which alleles are present on each homologous chromosome—that is, the genotype. For example, a fruit fly with the purple-eye allele on both chromosome-3 homologues is homozygous for purple eyes and will physically show purple eyes (i.e., it will have the purple-eye phenotype). If, however, the fruit fly has the purple-eye allele on one chromosome and the normal, red-eye allele on its homologue, then it is heterozygous for eye color. The allele appearing in the phenotype of heterozygous individuals is the dominant allele and the one hidden in the heterozygous condition is the recessive allele. Red eyes are dominant over purple eyes; therefore, flies in the example above would have the red-eye phenotype, but have a heterozygous purple-eye genotype. Recessive traits are only expressed in homozygous genotypes..

Articles must come from a reputable source (no Twitter, Facebook or Wikipedia), be submitted a copy of or link to the article must be included in the submission. Students should write a paragraph on their thoughts about stakeholder mapping. Solution Stakeholders are individuals or organizations that will be affected in some significant way by the outcome of the evaluation process or that are affected by the performance of the intervention, or both. Not all stakeholders have the same stake in the interventions and it is important to recognize the level of influence each stakeholder has on the project and its evaluation. This information will guide the data-collection process and allow you to identify the stakeholders who will serve as the main sources of data for the evaluation.

Can you think of a situation in which this knowledge would help diagnose a failure to boot? c).Why is it that the installation of Linux in a dual-boot configuration can cause problems for the Windows OS? 2. The use of solid state memory in lieu of a hard drive is starting to receive some attention. a). What benefits or drawbacks could crop up for this new type of secondary storage? b). In what way is solid state memory subject to the same failure as a hard drive? Solution A master boot record is a special sector of data at the very start of the device which is marked as bootable. It can reside on a hard disk partition, a CD / DVD, a pen drive or any other form of storage. The MBR is a small piece of executable code (usually micro instructions) that is executed at the startup by the system. The address of the MBR is fixed and during system startup, this location is accessed and read. If the MBR is found in this location, it is executed by the system, else error is thrown. The MBR primarily contains 2 things: Ans 1. Some BIOS use a different location like Compaq, which uses 0x07C0:0x0000. Although this resolves to the same memory location in read mode, it should be avoided. The Initial Program Loader (IPL) of the BIOS starts executing the MBR by passing control to this location. Prior to execution, it is setup with the following CPU registers: Ans 2..
