Turing machine A that does the following:

• On its first and second tape, A receives two strings w and v, w, v ∈ {0, 1}? , representing two integer numbers. When machine A is started, the tape heads are located on the left-most position, on the most significant bits of w and v.

• If none of the inputs w and v is the empty word, the Turing machine A writes the binary representation of the sum of the two integer numbers w and v on the third tape and then accepts the input. If one of w or v is the empty word, the Turing machine does not write anything on the third tape and rejects the input. If machine A outputs something, it outputs the binary representation of the sum in such a way that the left-most bit contains the most significant bit of the sum. Be careful: w and v may be of different length.

Q: Define a 3-tape Turing machine M that implements multiplication, in a manner similar to how A implements addition

IT Consulting Proposal

For this assignment, assume you have been hired by Kris Corporation as an Information Technology consultant. Kris Corporation manufacturers parts for the automotive industry. Your job is to submit a proposal that meets their criteria (listed below) based on information provided. You may fill in any gaps in the specifications provided by making assumptions. All assumptions should be clearly identified.

Current Implementation and Concerns:

• Parent domain (kris.local) and child domain (corp.kris.local) for the organization's AD infrastructure are running on Server 2012. The upgrade to AD is Server 2016. The following are concerns related to AD: (1) Kris Corporation is concerned about running multiple domain, and (2) automobile manufacturers are asking Kris Corporation to use single identity to procure orders in real time.
• The company has five locations: Atlanta (GA), Baltimore (MD), Chicago (IL), Seattle (WA) and San Diego (CA). The manufacturing plants are in Atlanta and Seattle.
• Disaster recovery is a big concern.
• Physical space for servers is an issue at the Atlanta location.
• Most of the IT staff is in Atlanta, which is the company's headquarters, but other locations have significant IT personnel as well. Business personnel are similarly distributed across the company's locations.
• Since all locations are independently connected to the internet, file sharing is difficult among sites.

Your document should integrate the content presented in the course. The outline below provides required points to cover. You are free to add other related information.

Describe the technical and business reasons for each choice, citing other resources as appropriate. The Windows Server 2012 operating system should be used for all aspects of the solution. Each choice should be explained with technical and business reasoning. Solutions should be reasonably detailed.

Your solution should cover the following five numbered areas and associated bulleted items listed under each.

1. Active Directory

• Why and how should the company migrate to 2016 AD?
• Should the company remain at multi-domain model or migrate to single domain?
• What technology can provide single sign on? How will it be configured?

2. DNS

• Where should DNS servers reside?
• What kind of DNS security can the DNS servers leverage?

3. DHCP

• Will a form of DHCP fault tolerance be implemented?
• How can DHCP addresses be tracked?

4. Hyper-V

• Evaluate the pros and cons of implanting Hyper-V. Would it need clustering?
• What features of Hyper-V can Kris Corporation leverage?

5. Routing/Security

• How can Kris Corporation improve its networking capabilities in terms of file sharing and security?

Submission Requirements:

• The final submission should provide 8-10 pages in length (not counting title page, images, diagrams, tables, or quotations).

Suppose that the U.S. military deploys the X-47B, an unmanned aerial drone capable of sensing, tracking, identifying, targeting, and destroying an enemy target with very limited human oversight—assume it is a human-on­-the-loop weapon. As a weapon in the ongoing conflict with the Islamic State (ISIS) terrorist organization, X-47B is tasked with missions to target and kill senior ISIS operatives. Now imagine a particular mission, in which an X-47B is given a programmed mission to carry out a targeted strike on two ISIS operatives, call them ‘V’ and ‘Z’, whom surveillance reports indicate are currently located in northern Iraq near the Turkish border. According to reliable intelligence, V and Z are instrumental in planning and leading operations to ransack, pillage, and then demolish world historical sites in Iraq (e.g. Khorsabad, Nergal Gate at Nineveh, and Monastery of St. Elijah), looting priceless antiquities and smuggling them to be sold on black markets in Europe and Asia, in order to generate capital to fund ISIS’s continued armed insurgency [for more on this particular practice, see Harkin, “Murdering History,” Smithsonian, March 2016]. V and Z are thereby deemed legitimate and high-value military targets. They are also elusive, with fairly sophisticated clandestine methods for relocating and evading detection; finding their present location required substantial surveillance drone resources over the course of several months.

Further suppose, that you are also in northern Iraq in a village near the Turkish border, working for a humanitarian aid organization providing healthcare services to Kurdish people whose communities have been ravaged and infrastructure degraded by ISIS. Part of your duties involve going out into local villages to distribute medical supplies and provide support services at community centers. Your team is primarily composed of American, British, and German nurses and doctors. Today, you are at one such community center providing care and supplies to hundreds of civilians. In a building 200 meters from the center in which you are working, V and Z are plotting another raid on a nearby historical site. The X-47B has accurately tracked and identified the location of V and Z, it also recognizes that the nearby community center contains many innocent non-combatants. Nevertheless, X-47B calculates that launching a precise and limited strike on V and Z’s suspected location will only produce a blast radius of no more than 75 meters, and determines that the identified non-combatants are not likely to be harmed. After computing its decision-procedure algorithm, X-47B fixes its target and initiates a missile strike to complete its mission, and no human overrides its lethal decision. V and Z are immediately killed, but the building was also housing several tons of explosives used in their demolition of historical sites. X-47B’s calculations did not account for the unknown explosives, which extend the blast radius of the strike to 225 meters. A wing of the community center collapses from the force of the blast, killing 15 civilians and one American nurse on your team, many others are severely injured and a British doctor is trapped under some of the rubble. After overcoming the initial disorientation from the blast, you and your remaining team rush to minimize casualties and treat the civilian victims.

[5 pts.] Was X-47B justified in initiating the missile strike to eliminate V and Z? Why or why not? Use principles of distinction, proportionality, or military necessity invoked in international humanitarian law governing armed conflict to defend your position.

[5 pts.] Who should be held morally responsible for the unintended harms and casualties? As a witness to the atrocity and possible victim, in this hypothetical case, how do you propose that the U.S. military should respond to the consequences of the X-47B’s strike? Defend your position.
