COP 3530, Discrete Data Structures and Algorithms, Summer 1999, Homework 2 :: UFL Florida Computer Programming Homework

Class Notes: Data Structures and Algorithms Summer-C Semester 1999 - M WRF 2nd Period CSE/E119, Section 7344 Homework #2 -- Due Fri 28 May 1999 : 09.30am * Question 1. Assume that an n-element array (vector) a contains distinct integers arranged in no particular order. Write an algorithm to find the value and location of (a) the mean of a and (b) the value v in a closest to the mean. Note: If v equals the mean, then v is the value closest to the mean. Example. If a = (1,2,3,5,4,6,7,9), then the mean equals 37/8 = 4.625. The value 5, which is in the fourth location (i = 4), happens to be the value closest to the mean. Answer: FindMean(a : array [1..n] of int): { sum = 0; posmean = -1, posclose = -1 for i = 1 to n do: sum = sum + a[i] endfor mean = float(sum) / n mdif = 9E13 for i = 1 to n do: dif = abs(a[i] - mean) if (dif if (dif = 0) then

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant, the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC, plenum, plenum cable, and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets.Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations. This system is mostly used in data centers. 3. Patch Cords: a short cord with a plug at each end, or a plug at one end and a pair of clips at the other, used for temporarily connecting two pieces of equipment or signal paths. 4. Connectors: A device for holding two parts of an electrical conductor in contact. 5. Conduit: A tube or duct for enclosing electric wires or cable. 6.Racks: A computer rack (commonly called a rack) is a metal frame used to hold various hardware devices such as servers, hard disk drives, modems and other electronic equipment. Some may refer to a rack as â€Å"LAN or network furniture† as resembles a shelving structure where components can be attached vertically, stacked on top of one another. A computer rack can also be called a relay rack or open rack. 7. Punch-Down Blocks: is a type of electrical connection often used in telephony. It is named because the solid copper wires are â€Å"punched down† into short open-ended slots which are a type of insulation-displacement connectors.These slots, usually cut crosswise (not lengthwise) across an insulating plastic bar, contain two sharp metal blades which cut through the wire's insulation as it is punched down. These blades hold the wire in position and make the electrical contact with the wire as well. 8. Consolidati on Points: an optional device for interconnecting horizontal cables between the Horizontal Cross-Connect and the Telecommunications Outlet or MUTOA within a structured cabling system. 9. Crimpers: A tool used to crimp, to join two pieces of metal 10.Fish Tape : a flat tempered spring-steel tape or wire used in pulling electric wire and cables (as into conduit runs) —called also snake wire 11. Continuity Tester: is an item of electrical test equipment used to determine if an electrical path can be established between two points;[1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus 12. Category 5e/6 Cable : cabling is used as a cabling infrastructure for 10BASE-T (Ethernet), full duplex 100BASE-TX (Fast Ethernet) and 1000BASE-T (Gigabit Ethernet, or GbE) networks.The Cat 5e standard provides performance of up to 100 MHz and can be used up to a maximum length of 100 meters. 13. Binder Groups: A group of wire pairs bound together, usually by some sort of color-coded plastic tape or thread. In a large twisted pair cable, there may be many pairs combined into binder groups of 25 pairs for ease of connectivity management. Each pair within a binder group is uniquely color-coded for further ease of management. See also cable and wire. 14. Hybrid/Composite Cable : composite cable A communications cable having both optical and metallic signal-carrying components.Note 1: A cable having optical fiber(s) and a metallic component, e. g. , a metallic twisted pair, used solely for conduction of electric power to repeaters, does qualify as a composite cable. Note 2: A cable having optical fiber(s) , plus a metallic strength member or armor, does not qualify as a composite cable. Hybrid †¢An optical communications cable having two or more different types of optical fibers, e. g. , single-mode and multimode fibers. 15. Pulling Cable : The act of pulling the wires, as of a puppet; hence, se cret influence or management, especially in politics; intrigue 6. Wavelengths of Light: The length of a single cycle of a wave, usually measured from crest-to-crest. For electromagnetic waves 17. EMI : is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device. 18. Optical-Fiber Strand : Is this referring to the actual pure glass on the middle of the fiber 19. Index of Refraction : the ratio of the velocity of light in a vacuum to that in a medium. 0. wordnetweb. princeton. edu/perl/webwn 21. Cable Jacket : The outer protective coating which covers the core of the cable.. 22. Cladding Size : A metal coating bonded onto another metal under high pressure and temperature. 23. Multifiber Cables : Fiber optic Cable bearing many fibers independently sheathed and capable of carrying unrelated signals. They often surround a central strength member, a nd can be either loose- or tight-buffered. One standard configuration is a 12-fiber cable. 24. Differential Mode Delay: 25.In an optical fiber, the variation in propagation delay that occurs because of the different group velocities of different modes. Synonym multimode group delay. 26. Chromatic Dispersion : In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency,[1] or alternatively when the group velocity depends on the frequency. Media having such a property are termed dispersive media. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength-dependent nature, or group-velocity dispersion (GVD) to emphasize the role of the group velocity

Questions to Ask in a Grad School Admissions Interview

An invitation to interview at the graduate program of your choice is an amazing opportunity to let the graduate committee get to know you - but the purpose of the grad school admissions interview is also for you to learn about the graduate program. All too often applicants forget that they too are conducting an interview. Take advantage of the opportunity an admissions interview offers you good questions that will gather the information that you need to determine if this is the right program for you. Remember that you are interviewing the graduate program - you must choose the program that is right for you.   Asking good questions not only tells you what you need to know about a graduate program, but it tells the admissions committee that you are serious. Good, genuine, questions can impress admissions committees. Questions to Ask During a Graduate Admissions Interview What characteristics are specific to this program and distinguish it from competitors? (Be sure to refer to specific characteristics)Where are recent alumni employed? What do most students do after graduation?What types of financial aid are offered? What criteria are used for choosing recipients?Are there any scholarships or fellowships available? How do I apply?Are there teaching opportunities, such as teaching assistantships and adjunct positions?Do most students publish an article or present a paper before graduation?What applied experiences are included in the program (e.g., internships)? Ask for examples of internship placements.What is the relative importance of admissions test scores, undergraduate grades, recommendations, admissions essays, experience, and other requirements?Does the department prefer applicants immediately out of undergraduate programs or do they prefer applicants with work experience? If they prefer or require experience, what kind of experience are they lo oking for?How are mentoring and advising relationships established? Are advisors assigned?How long do most students take to graduate? How many years of coursework? How long do most students take to complete their dissertations?Do most students live near campus? What is it like to live in this area as a graduate student?How closely do students work with faculty? Is it common for students and faculty to publish together?How long does the average student take to complete a dissertation, roughly?How is the dissertation process structured? Are committee members assigned?
