Reflection Paper - 948 Words

For most people, they learn how to improve their reading and writing skills in Elementary School easily. I am one of the few that had to put more effort to improve our reading and writing. Some also may say that one event was the only event that affected their writing styles to make them to what they are now. I believe it takes more than one event to define how we behave, write, or interact. It takes multiple events to help shape how we write, such as, having extra help from the school, having a teacher sit down and talk with you, or having parents put more effort towards you practicing. I came from a Spanish speaking household and I still do to this day. Having my first language as Spanish and not English caused me to learn English later†¦show more content†¦I felt relieved and did not worry as much because I thought it was a simple warning and it would not be bad. Then she told me I could fail, that is when my worries came back but more intense. I stopped hearing everything she was saying as my mind started to drift off thinking about my parents giving me a spanking, taking my games away, grounding me, and all the other punishments they could possibly give me. It became even worse when she told me that she is going to send the grades home and that I need to have my parents sign it. When I got home I was extremely nervous to show my mom the grades. When I finally got the courage to tell her she got upset and started yelling things that I should not repeat here. After she got done yelling I promised I would try to get good grades and not be lazy so that I do not get behind. My mom decided that she will have to force me to read and practice writing because I am a lazy person. Because she knows I am lazy, she does not believe I will study and practice to bring my grades up. Every day while she was cooking she would sit me at our kitchen table and would have me read out loud for her. The book I read did not matter to her if I read a book at my grade level or higher. I do not enjoy reading books for fun so I did not have any in my room for me to choose from. My older sister is a big book nerd and enjoys reading lots of books for her free time.

Literature Review of Fault Tolerant Systems Free Essays

CHAPTER-2 PROBLEM STATEMENT Aim of the undertakingis to build Fault Tolerant System. Fault Tolerant system is a system which runs efficaciously in any status. Even if there is a mistake in the processor our system will observe it and advise to user or admin. We will write a custom essay sample on Literature Review of Fault Tolerant Systems or any similar topic only for you Order Now It will non merely notify but we are seeking that it will take mistake over the air. Triple Modular Redundancy is bosom of our system ; it detects the mistake through vote system. To build a CFTP design is a truly complex work and needs a important sum of clip to complete. In order to hold a flawless design, tonss of conditions need to be considered and all jobs should be solved in a sensible manner. Choosing constituents may take few yearss or months depending on how much information or information is collected. Decisions may still be changed at the last minute due to some unpredictable state of affairss or inevitable factors. Any alteration in the concluding design on a constituent sometimes will do a series of alterations to others. It is obvious that constructing a fully-functional CFTP does take much attempt and interior decorators have to truly understand how circuits relate each other in order to revise or debug it. Unfortunately, graduate pupils at Naval Postgraduate School merely stay a short sum of clip. A large design like CFTP is chopped into several sections and assigned to different pupils. In this clip restraints, pupils non merely necessitate t o recognize what old pupils have done but besides take up a design in advancement. Largely, pupils picking up the sections do non hold a opportunity to larn straight from pupils who have worked on this design earlier. Therefore, thesis becomes an of import interface of experience heritage between coevalss of pupils. CHAPTER-3 LITERATURE REVIEW 3.1 LITERATURE SURVEY: – 3.1.1. Lashomb’s Design Peter A. LaShomb expressed many constructs in both TMR design and FPGA choice. Traditional solutions for radiation effects were introduced including hardware redundancy, like Quadded Logic, and package betterment for mistake tolerance, like clip redundancy or package redundancy. In the TMR subdivision, RADHARD and COTS were compared in handiness, public presentation and cost. Potential benefits of those two were clearly described as good. The processor used in his TMR design was KCPSM, an 8-bit microcontroller. It was free downloaded from Xilinx’s web site and served as a readily available test-case processor while waiting handiness of other high public presentation processors. Constructing and testing of the TMR were done on Xilinx Foundation series package which was available at Naval Postgraduate School ( NPS ) . Voters and an mistake encoder were designed and explained in item. Other issues including interrupt modus operandi and memory/error accountant were left as follow- on research. In the FPGA subdivision, different FPGAs were compared in a figure of facets. Five major parametric quantities for taking a good FPGA were gate count, handiness of hardware and package, bundles ( flat-pack vs. ball-grid-array ) , re-programmability and radiation tolerance. The Xilinx XCV800 was chosen as the campaigner at that clip for future execution [ 25 ] . 3.1.2. Ebert’s Research A complete CFTP conceptual design presented was in Dean A. Ebert’s thesis. For hardware considerations, his thesis discussed why specific constituents were chosen and how french friess communicated in an incorporate circuit. More item and realistic constructs about FPGA and CFTP constellations were described than earlier and french friess were selected based on a figure of space-environment considerations. Discussion of system memory was of import and first described in this thesis. Memory constellation accountant, functional logic and glue logic were besides new thoughts ne’er talked about in old work. The TMR circuitry was non one of the chief subjects in his research, but from his work one can visualise the external connexions of the FPGA and understand the function of TMR in the CFTP procedure. Figure 4 illustrates the layout of the board he developed The CFTP will be launched into LEO orbit on two orbiters, NPSAT-1 and Mid- STAR-1, in 2006. How the Department of De fense and Navy Space Experiment Review Board ( SERB ) and the Space Test Program ( STP ) Office were involved with these two orbiters was described in his thesis. Other paperss related to plan descriptions and demands of the STP office were attached every bit appendixes as good [ 26 ] . 3.1.3. Johnson’s Implementation Steven A. Johnson [ 5 ] focused his work on TMR design. The indispensable constituents to do a circuit be fault-tolerant were identified. Circuits designed in Lashomb’s thesis could non be used due to different design architecture and the important ascent of computer-aided-design package employed. Basic constructs for building a TMR circuit were still the same, but implemented in a different manner. All processor end product signals have to be voted. Interrupt was compiled in a province diagram and used to trip the interrupt service modus operandi to rectify an mistake inside the processor.ESSDwas used to salvage the mistake syndrome in order to offer a log file for analysis. The off-chip memory for the CFTP is Von Neumann architecture. The Von Neumann architecture has merely one reference coach and one information coach. Due to this difference, aConciliatorwas designed to organize different timing restraints in order to do a proper read and compose on memory. Normally, TMR communicates withConciliatorin order to entree memory. Meanwhile, the syndrome informations is latched intoESSDirrespective of an mistake happening or non. When an mistake occurs, a signal will be sent to disrupt and starts the Interrupt Service Routine ( ISR ) . At this minute, KDLX is stalled andESSDsaves the mistake syndrome to memory throughConciliator. Then interrupTgenerates a TRAP direction to KDLX and leads the whole circuit into an mistake rectification status. When KDLX sees the TRAP direction, it jumps to a specific memory location and the plan counter value before the leap is saved in an interrupt reference registry ( IAR ) , a particular registry inside KDLX. In the mistake rectification status, the contents of all registries inside KDLX are saved to memory through electors. Then, each registry is reloaded from memory. The intent for making this measure is to rectify any incompatibilities of the registries in all three KDLX processors. Since all contents ha ve to go through electors while salvaging, any mistake inside any registry will be corrected [ 26 ] . 3.1.4. N-Modular Keun Soo Yim, et.al. [ 8 ] nowadayss fault-tolerant, programmable elector architecture for software-implementedNitrogen-tuple modular redundant ( NMR ) computing machine systems. Software NMR is a cost-effective solution for high-performance, mission-critical computing machine systems because this can be built on top of commercial off-the-shelf ( COTS ) devices. Due to the big volume and entropy of voting informations, package NMR system requires a programmable elector. Our experiment shows that voting package that executes on a processor has the time-of-check-to-time-of-use ( TOCTTOU ) exposures and is unable to digest long continuance mistakes. In order to turn to these two jobs, we present a special-purpose elector processor and its embedded package architecture. The processor has a set of new instructions and hardware faculties that are used by the package in order to speed up the vote package executing and turn to the identified two dependability jobs. We have implemented the pr esented system on an FPGA platform. Our rating consequence shows that utilizing the presented system reduces the executing clip of mistake sensing codifications ( normally used in voting package ) by 14 % and their codification size by 56 % . Our mistake injection experiments validate that the presented system removes the TOCTTOU exposures and recovers under both transient and long continuance mistakes. This is achieved by utilizing 0.7 % excess hardware in a baseline processor [ 27 ] . How to cite Literature Review of Fault Tolerant Systems, Essay examples

Essay About Survival Of The Fittest Example For Students

Essay About Survival Of The Fittest Charles Darwin felt strongly that observations made on large scale explorationssuch as his voyage on the Beagle showed conclusively that many clearly differentorganisms, animals as well as plants, were related to one another buy someunknown law. In other words Darwin was trying to prove that evolution existed.However Darwin does outline how a purely natural process of selection couldproduce similar effects, and thus explain the development of new species withoutreference to supernatural intervention. Taking that into consideration, Ibelieve that by Natural Selection Darwin is trying to portray thestruggle for existence and adaptation for survival among living things. WithNatural Selection, Darwin used this term to explain the casual mechanism, whichis responsible for the operation of his theory. He would go about and abandonhis term in favor of the term Survival of the Fittest. Although he receivedcriticism from so many of his peers for using Natural Selection, the term isquite important because virtually all biologists used it as the explanation forthe mechanism. A main reason why Natural Selection was not very popular wasbecause evolution requires enormously long periods of time, that the everydayexperience of human beings provides them with no ability to interpret suchhistories. Looking at Darwins position, Survival of the Fittest had a greatmeaning on the struggle for existence and Darwins emphasis on abundance. Firstlooking at Survival of the fittest, its a phrase that describes the outcome ofa competition where there is no possibility of predicting the outcome in advancebecause of the complexity of the conditions of the competition. It describesonly the effect or outcome of an event by its very nature and regardless of thesituation in which it is used. For example, if it were used to describe theoutcome of an auto race such as the Nascar, using the term, It will be survivalof the fittest would indicate that the victor would be unknown until theend of the race. Similarly, if discussing the survival of a business in acollapsing economy or perhaps the survival of a race of people during fiercewars would indicate that nothing would be known about the outcome until the endof the particular event. Secondly Survival of the Fittest was used extensivelybecause it was a better, more descriptive, explanation of the mechanism of whichevolution occurred. The term contains an implicit assumption that survivors arean improved form of organism compared to those, which do not survive. Althoughintelligence is a key to improvements it is not however true for the field ofbiological reproduction. There is no human intelligence available to weed outthe defectives and alter the process toward a more desirable end. As moreindividuals are produced that can possibly survive, there must in every case bea struggle for existence, either one individual with another of the samespecies, or with the individuals of distinct species, or with physicalconditions of life. Keeping that in mind, I came upon one of the greatestmysteries of biological history, the vanishing of the dinosaurs. Here Survivalof the Fittest plays a routine role because the fittest were some form ofbacteria. Does that mean that the smaller the organism the more chances of it tosurvive? A look at the fossil record shows that 99. 99% of the survivors weresimpler organisms and the survivors that we know of today are not the 0.01% ofsurvivors that are more fit from a complexity standpoint and thus prove themethodology of the theory. So what does the term fittest mean? It is speculatedthat the term fittest refers to an organism which has the bestcapability for acquiring and using all the available nutrients, all whiledeveloping or having a capability of fending off physical threats to itsexistence. However this concept would indeed be an explanation for a certaintype of organism. .u1656a888b25a51496e82b195138ed4bb , .u1656a888b25a51496e82b195138ed4bb .postImageUrl , .u1656a888b25a51496e82b195138ed4bb .centered-text-area { min-height: 80px; position: relative; } .u1656a888b25a51496e82b195138ed4bb , .u1656a888b25a51496e82b195138ed4bb:hover , .u1656a888b25a51496e82b195138ed4bb:visited , .u1656a888b25a51496e82b195138ed4bb:active { border:0!important; } .u1656a888b25a51496e82b195138ed4bb .clearfix:after { content: ""; display: table; clear: both; } .u1656a888b25a51496e82b195138ed4bb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u1656a888b25a51496e82b195138ed4bb:active , .u1656a888b25a51496e82b195138ed4bb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u1656a888b25a51496e82b195138ed4bb .centered-text-area { width: 100%; position: relative ; } .u1656a888b25a51496e82b195138ed4bb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u1656a888b25a51496e82b195138ed4bb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u1656a888b25a51496e82b195138ed4bb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u1656a888b25a51496e82b195138ed4bb:hover .ctaButton { background-color: #34495E!important; } .u1656a888b25a51496e82b195138ed4bb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u1656a888b25a51496e82b195138ed4bb .u1656a888b25a51496e82b195138ed4bb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u1656a888b25a51496e82b195138ed4bb:after { content: ""; display: block; clear: both; } READ: The Last Seven Months of Anne Frank- Willy Lindwer Essay For example, there are many coral deposits throughout theworld, some which are immense in size such as the body coral, which is currentlyin Florida. Unfortunately marine coral is really not an organism, but rather acollection of organisms. Since there are really no such organisms in existenceas described above, it must be concluded that this is not what thefittest is, in the sense of Darwins meaning. The termfittest as contained in Survival of the Fittest can only beconstrued as the organism fitter than other members of organisms falling into aspecial group. This is consistent with the descriptions used by Darwin and alsoused by most evolutionists in the explanation offered for the mechanism ofevolution. A quick look in the animal kingdom shows the rapidly reproducingFruit Fly, with a serious deficiency that being the inability to penetrate theskin of even the thinnest of fruit, and thus release the sugars which begin theprocess which produces their food. These mechanisms are available in thousandsof organisms, both in the animal and vegetable kingdoms. Many mechanisms such asin the mosquito, stingers, bee/wasp, or a dissolving fluid such as produced byother insects abound in nature. It is inexplicable in the Darwinian sense, thatsome advice or method of doing this would fail to be developed over the pasteons of their existence. It must be concluded that while they are survivors,they are not the fittest. This leads to the fact that Darwins theory has notexplained the existing spectrum of living organisms either in the initialdevelopment from the mineral state or in the highly developed state in which itexists today. In conclusion, Darwin stresses that nothing is easier than toadmit in words the truth of the universal struggle for life. Darwin also pointsthat in looking at Nature, it is most necessary to never forget that everysingle organic being around us may be said to be striving to the utmost increasein numbers. He says that each lives by a struggle at some period of its life:that heavy destruction inevitably falls either on young or old, during eachgeneration or at a recurrent intervals. We behold the fact of nature bright withgladness, we often see superabundance of food, and that the birds which are idlysinging round us mostly live on insects or seeds and thus constantly destroyinglife. Darwin makes it clear that the structure of every organic being isrelated, in the most essential yet often hidden manner, to that of all otherorganic beings, with which it comes into competition for food or residence andfrom which it has to escape, or on which it preys. This is obvious in thestructure of the teeth and talons of the tiger, and in that of the legs andclaws of the parasite, which clings to the hair on the tigers body. Afterlooking at all the examples it turns out that this is an unabated belief systemwhich underlies the study of all the physical sciences. The most important ofthese beliefs is that all phenomena in the universe are capable of beingmeasured or acknowledged, by one of the five senses of man. It ought to be notedthat to evolutionists, there is no objection to philosophy being a part ofscience and the fact that it is absolutely unthinkable to them that religion bea part of it only shows a bias of the same sort that keeps Darwins theoryalive. But we must not forget that neither philosophy nor religion is a properconsideration of the physical sciences and the theory of Charles Darwin. At lastI must say this was a fascinating project and for years to come Darwins theorywill explore many questions of nature and survival that are not yet cleared andwill solve many mysteries that we have not solved.

The Exclamation Point Avoiding Overuse

Besides the comma, there’s probably no punctuation mark more overused than the exclamation point. Marketers, pulp fiction writers and overexcited people in general just love them. Unfortunately, too many exclamation points in your copy will make your audience feel that your writing is disingenuous. As with most things, exclamation points are best used in moderation. To get people to take you seriously, it’s important to use them correctly and effectively. A few common pitfalls for exclamation point misuse are: 1. At the end of a sentence Exclamation points should generally be used alone at the end of a sentence, since they are technically terminal. It shouldn’t be followed by a question mark or period, even when the exclaimed sentence is a question. Incorrect: How did you get in there?! Correct: How did you get in there! This rule is disregarded so often that it almost feels counter-intuitive. But the exclamation mark is strong enough to stand on its own without the help of a question mark, even if you really want it to be there. 2. In the middle of a sentence Sometimes you’ll have quotations in the midst of a sentence that end with an exclamation point. When this happens, omit the comma (the exclamation point, as terminal punctuation, trumps the comma). This one is definitely consistently misused. Incorrect: â€Å"There’s a fire!,† she yelled. Correct: â€Å"There’s a fire!† she yelled. 3. When citing a title Some books have exclamation points in their titles (as mentioned above, pulp fiction writers love them). When using a title or proper noun in a sentence, the exclamation point is considered part of the title and not punctuation, so a comma afterward is necessary. Correct: I was watching the movie Them!, and it was really hokey. As you can see, exclamation points aren’t too difficult to use correctly. Pair this with discerning use to effectively deliver your message to your target audience.

From the precpective of the human cognitive abilitis are current Essay

From the precpective of the human cognitive abilitis are current computer well designed - Essay Example Here, according to Zaphiris and Ang (2009), human perception, memory, and attention are important because these are crucial in ensuring the minimal use of their efforts and interaction with technology in the ultimate aim of enhanced human-computer interaction –. (p. 2550) In the context of human-centered design, it is posited that there should be a convergence of the content information, the user, the designer, and infrastructure along with the enhancement of communication effectiveness. Norman suggested three requirements for a computer design that effectively addresses the human cognitive abilities. These are: 1) conceptual models which make invisible functions visible by using feedback, as the effect of an interaction, and explanations of its use; 2) constraints which are proactive measure to limit the choices of interaction and reduce human errors; and, 3) affordance is the perception and actual properties of the thing. It suggests how the device can be possibly operated. (cited in Zaphiris and Ang 2550) With these variables in mind, it is easy to understand how the current computing technologies are well designed. Computers are currently designed after through analysis and synthesis of individual needs, cultural practice, preferences, and, yes, cognitive ability of its users. A specific demonstration of this is computer developers’ preoccupation with usability, visibility and functionality. In developing a computer operating system, for example, companies such as Microsoft and Apple are bent on reducing errors of everyday life by designing systems that feature easy navigation system, user-friendly environments, functional interface, memorability, lack of errors and user satisfaction, among other variables. This is also shown in the way designers create interaction tasks, techniques, devices and applications. The input-output relationship that characterize

Air Pollution in the USA Essay Example | Topics and Well Written Essays - 1000 words

Air Pollution in the USA - Essay Example Air pollution is a very important topic for discussion and research since air itself is required for every creature and living thing on the surface of the planet. Not only on land but also in water since air pollution has an effect on the level of contaminants in the sea as well. Undoubtedly, air pollution levels have been rising in the recent past and the overall blame for that is given to human activity and the industrial and commercial ventures of civilization as a whole. While the effects of air pollution on the environment are often disastrous and not easily reversible, the central issue with air pollution concerns itself more with the quality of life on the planet. Since human beings are the predominant creators of air pollution and they are also the life form which objects violently to air pollution, the solution for the problem also has to come from them. There are several ways and means which are currently being utilized to prevent air pollution from becoming a mammoth problem and some of those are discussed in this paper. Method The research for this paper was conducted in the library and various electronic and manual sources were utilized to locate the information which is connected with air pollution, its effect on the environment and the means by which it can be prevented. After a quick reading of collected materials, five sources were selected for detailed examination with which the ideas and constructs presented in the paper were eventually formed. The results from the research clearly show that the largest and most significant causes of air pollution are the industrial and commercial activities of humans.
