Unit 10 Lab 1 Building a New Structure Problem Analysis
Ryan
11/13/
Fiber optic cable was once reserved for high-performance needs, but today it’s turning up in all kinds of networks. If you’re familiar with copper cable, you’ll quickly discover that fiber optic cable is a completely different animal. Not only is the installation process different for fiber, but also the troubleshooting process. Fiber optic cable is also far more fragile than copper cable, so there are more potential causes of trouble. I’ll discuss common fiber optic cable problems and how to diagnose and repair them.
The most common causes of fiber optic malfunctions
Anyone who’s ever done network troubleshooting knows it’s a complicated process, so it’s helpful to know where to start looking for a problem. To help you make an educated guess about the cause of your network’s troubles, here are some of the most common fiber optic cable problems with their possible causes: * Broken fibers because of physical stress or excessive bending * Insufficient transmitting power * Excessive signal loss due to a cable span that’s too long * Excessive signal loss due to a contaminated connector * Excessive signal loss due to faulty splices or connectors * Excessive signal loss due to having too many splices or connectors * Faulty connection of fiber to the patch panel or in the splice tray
Typically, if a connection is completely dead, it’s because of a break in the cable. However, if the connection is intermittent, there are several possible causes: * The cable’s attenuation may be too high because of poor quality splices or too many splices. * Things like dust, fingerprints, scratches, and humidity can contaminate connectors. * There is low transmitter strength. * There are bad connections in the wiring closet.

...Master plan Questions What body system/s does the virus attack? Would it have a different effect on Ancients? How can/does it spread, exactly? Where did it originate? How long can it last outside of a host’s body? Does it effect animals other than humans? Is this virus related to the one that killed off a large chunk of the Cetra population? Now, what did you say the symptoms were again? What is this virus called? Ideas Worldwide spread of plague, total annihilation Bad because no more people equals no more RP Good because death and destruction are fun. Possibility: Unlikely A few more characters are introduced, claiming they’re scientists. They go to ShinRa, offering the cure. They turn out to be part of a vast colony of hidden Cetra, the likes of which have never been seen before. Possibility: Possible The plague spreads planetwide until a cure is developed or other forces step in Possibility: Almost certain Tace, Meus, and Laeta, (DNA possibly affected by virus) reappear, vowing their revenge on Lacri/Selen and Risus for abandoning them Possibility: Good Risus dies, but Lacri survives (If Tace, Meus and Laeta are effected, then Lacri gets the effect twice as badly.) Possibility: Good Mina gets sick, tries to hide it, and ends up almost dying before someone, preferably Lisone, cures her Cons: Lame Possibility: Maybe Virus is cured before Lacri and Risus’ death.

In the last three paragraphs of Chapter 13 of Survival in Auschwitz, Primo Levi describes a man called Kuhn praying aloud, “thanking God that he has not been chosen” in “the great selection of October 1944.” In the title story of This Way for the Gas, Ladies and Gentlemen Tadek writes of “naked, sweat drenched men” crowding the barrack aisles, and “directly beneath me [. . .] a rabbi” reading from a Hebrew prayer book and “wailing loudly, monotonously” (Penguin, p. 31).

The Self According to Brecht

...survive. He strives to show how it is possible to be moral, however in the struggle for survival within society morality often becomes the victim to what needs to be done. This conflict between morality and necessity is personified in Shen Te and Shui Ta. Shen Te, the good woman of Setzuan, is instinctively kind hearted and incapable of refusing to help anyone in need. In the beginning of the play, despite her poverty she gives up her client for the night in order to board the three Gods that need a place to stay. As a reward for her kindness, the Gods give Shen Te one thousand silver dollars “Isn't it true she might do better if she had more money?" (Brecht 1941) and she uses the money to buy a tobacco shop. She is immediately assailed by some of the townspeople for help, beginning with Mrs. Shin the previous owner of the tobacco shop and then by the elderly couple (who had first boarded her when she arrived in Setzuan) and their extended family who move into the shop. Being overwhelmed, Shen Te withdraws and Shui Ta enters. Shui Ta is able to impose his authority on the parasites that descended upon the tobacco shop in a way that Shen Te could not, “You won’t find Miss Shen Te. She has suspended her hospitable activity for an unlimited period. There are too many of you. She asked me to say: this is a tobacco shop, not a gold mine” (Brecht, 1941). He prepares the shop for business, negotiates an appropriate price for the...

Mark 5, Lord of the Storm

...Tell the story: Mark 5:21-43 Pray Central truth we can learn from today’s story: In moments of desperation: God is there listening and responding even if it’s not on our timetable Let’s look at these two people: Jairus and the nameless woman 1) Jairus’ desperate situation Leader of the synagogue- had declared Jesus to be public enemy #1 So Jairus coming to Jesus shows his desperation- this probably will cost him many of his friends and maybe even his job, but he doesn’t care because his daughter is dying We know from Luke’s account that this girl is his only daughter- she’s 12 years old- so they’ve had 12 years of joy together and her life is about to begin- in this society, 12 was when you might get engaged and should’ve been an exciting time, but she’s sick- she’s dying. She needs Jesus. And so does her father. 2) Woman’s desperate situation Woman is complete opposite of Jairus- she was a social and religious outcast because of a disease- most likely a uterian cyst- that has caused her to bleed for 12 years- so she’s had 12 years of pain and disgrace- in this society, she didn’t have a life because of her illness OT law said she was unclean so that means she couldn’t partake in any religious ceremonies at Jairus’ synagogue. But it also meant that if she was married- she couldn’t have sex with her husband and if she wasn’t married, she probably wasn’t going to get married because she wasn’t supposed to be touched Not just sexually- any touch. That means...

New Urbanism

...because of the way they lend themselves to both oversimplification (unfinished sur faces) and open- ended abstract ion (“Memorabilit y as an Image”), Brutalism is often employed today as nothing more than a vague epithet lobbed at vast expanses of postwar institutional building; its associations with art practice are, more frequently than not, left out entirely. The purpose of dedicating this issue to New Brutalism, then, is both to reconsider its theses and to reevaluate its work and writings, while at the same time amending and supplementing earlier histories of the moment, which have emphasized the pop aspects of the work. 2 In doing so, we hope to recapture something of New Brutalism’s latent critical potential. As Theo Crosby wrote in the January 1955 issue of Architectural Design, New Brutalism positioned itself against the “contemporary”—“its veneer of ‘modern’ 1. Alison and Peter Smithson, “House in Soho, London,” Architectural Design (December 1953), p. 342; and Reyner Banham, “The New Brutalism,” Architectural Review 118 (December 1955), pp. 354–61, both of which are reprinted in this issue.

Personal Style Inventory

...an extrovert has been a great asset to me at my work at Target. On a normal 8 hour shift I come into contact with well over a hundred guests and will most likely interact with at least 30-40 asking where something is or if we have a particular product. As it is the Christmas season now I need to be extremely helpful with guest as well as be outgoing enough to ask a puzzled looking guest if I can “help them find anything today?” As well as the many guests I help, I have many coworkers; we have many new hired on because of the holidays, and many I don’t know their names. In order to work most efficiently and effectively, I need to introduce myself constantly so there is no confusion with “hey you’s.” Being an extrovert definitely helps with this kind of working environment. Of course, with how many guests and coworkers I come into contact there are plenty who are introverts and slow the process. Although being extroverted has helped me greatly in my retail job, it hasn’t helped me so much in day-to-day talking with people and a lot of sales associates. I know I tend to ramble a lot and when I’m making a purchase I tend to think aloud and give out more information then I really intend or need too. I recently purchased a laptop computer at best buy and the sales associate there had asked me what I would most likely be using it for, and instead of giving him a simple answer I instead told him a story about what kind of computer my friends at work were talking about and whether...

Molecular Gastronomy

...same? Many believe it represents a new culinary genre that those “out there” chefs do. Reactions to this new culinary movement range from enthusiasm, buoyant with foam sauces and bubbling liquid nitrogen, to perplexed looks or mutterings of disapproval. Some people’s understanding about molecular gastronomy appears to be free-form dots scattered over the culinary map, perhaps it’s time to connect those dots. Molecular gastronomy can be defined as the fusion of food science and culinary arts. New technologies and natural texturing agents can now be used to deconstruct any dishes and cocktails, enabling one to serve mojito bubbles and martini bites, as well as balsamic vinegar pearls and chocolate spaghettis. Molecular Gastronomy has become the name of the scientific discipline co-created by Nicholas Kurti and Herve This, based on exploring the science behind traditional cooking methods. Herve This identified five goals of this new science: “(1) to collect and investigate old wives’ tales about cooking; (2) to model and scrutinize existing recipes; (3) to introduce new tools, products, and methods to cooking; (4) to invent new dishes using knowledge from the previous three aims; and (5) to use the appeal of food to promote science.” Molecular gastronomy was born in 1988, when two scientists, Nicholas Kurti and Herve This, decided to investigate culinary transforma¬tions. This described molecular and physical gastronomy as the physics and chemistry behind the preparation of...

The Black Death

...blood. Nurses are madly dashing around from person to person, trying to aid them as much as possible, while our top doctors are desperately racing against time to find some sort of remedy; the hospital is in mass chaos I tell you, mass chaos! I just can’t take it anymore, seeing so many faces that were once smiling and laughing all of twenty-four hours ago to now being masked with such desolate fear and misery. I want to leave this place, just like Dr. Kamish and Dr. Maveroh and about ten more of our staff members that deserted our hospital did. It would be better than hiding in this old closet that I’m in now, which reeks of must and unused cleaning supplies. Although, the stench of dirt and Windex couldn’t possibly smell as bad as the vile odor of the sick and decaying people outside; I don’t want to go out there. I’m petrified. If I go back out there, I could get sick myself, and leave behind my husband and kids. But I can’t stay in here. It’s wrong. I’m going to go out there right now and try to do my best to help the people that have fallen ill during this grave time, the grimmest time of my life. -Sue * * * Dear Journal March 20, 1348 Yesterday at work was one of the most horrifying sights that I have ever had to witness.

Me I Am

...This week was a difficult one for me, a lot of new concepts and a lot of information was thrown at me but with the media tools I used this week it made it a little easier to get through this week and hopefully the next couple of weeks. One media that helped me in this week’s assignments was the direct chat section on the schools web page. Being able to be in communications with other students helped me understand some sections of this week that I did not understand. It also allowed me to bounce ideas and calibrate on this week’s assignment. Using the discussion board is great but being able to instantly communicate with our team allows us to work better with each other. Another media that helped me big time as the E-book, using the eBook from book shelf makes it easier to navigate back and forth between section and the highlighting section helps keep track of things that I might have to go back and read again or to highlight important section that I think will be needed. I believe this will come in handy later on down the line when it comes time to take the final. These two media tools where very useful this week as this week for some reason felt a little more challenging to me, being able to reach out to team members and have parts that where a little fuzzy helped somewhat clarify certain sections of the chapter. One last media tool or study tool that was very important to my self was the UOF app, I am not always able to be in front of my PC so being able to get on this app from...
