Use Of Information Systems On The Life Of Data - 910 Words

Use of Information Systems in the Life of Data Is there a way to differentiate between whether we know something presented in an Information System, whether we believe it, or simply have a piece of information. And further, is an information system a valid tool for moving our thinking up the hierarchy. Actions and decision are what matter most when you are traversing the DIKW hierarchy. There are many actions that can be taken, and decisions that can be made by information systems. In fact some might argue that certain decisions can only effectively be made with the assistance of technology. Humans have gone thousands of years without information systems and have derived knowledge out of practice and experience. The invention (discovery?) of Information Systems has only accelerated the speed and effectiveness of knowledge creation, transfer, and management. Decision Support Systems are prominent information systems used to aid in decision making within an organization. These systems take a variety of input and aid management in an organization in deciding between certain decisions. When there are conflicting results provided by both a decision support system and a human, you must make the decision as to which one is providing more credible results. HERE IS SOME MORE INFORMATION ABOUT THAT The tools we use today to aid in this conversion of data are extremely vast.

Definition and Examples of Subordinate Clauses

In  English grammar, a subordinate clause is a  group of words that has both a subject and a verb but (unlike an independent clause) cannot stand alone as a sentence. Also known as a dependent clause. Contrast this with a main clause and coordinate clause. Subordinate clauses are usually attached to main clauses or embedded in matrix clauses. Pronunciation: Suh-BOR-din-it Exercises Exercise in  identifying adverb clausesPractice identifying independent and dependent clauses Examples and Observations Whenever you find yourself on the side of the majority, it is time to pause and reflect.(Mark Twain)That spring, when I had a great deal of potential and no money at all, I took a job as a janitor.(James Alan McPherson, Gold Coast, 1969)Memory is deceptive because it is colored by todays events.(Albert Einstein)Bailey and I did arithmetic at a mature level because of our work in the store, and we read well because in Stamps there wasnt anything else to do.(Maya Angelou,  I Know Why the Caged Bird Sings, 1969)If you cant leave in a taxi you can leave in a huff. If thats too soon, you can leave in a minute and a huff.(Groucho Marx, Duck Soup)If a free society cannot help the many who are poor, it cannot save the few who are rich.(John F. Kennedy)When you lose your laugh, you lose your footing.(Ken Kesey)Every book is a childrens book if the kid can read.(Mitch Hedberg) Grammatical Juniors Subordinate clauses are grammatical juniors, dependent on the main clause for complete sense. They are not subordinate in any other way; they need not be stylistically inferior, and indeed may be more informative than the main clause they depend on, as in this example: If you go on with a diet that consists exclusively of cottage cheese, dry toast, and Brazil nuts, I shall worry. The main clause is I shall worry: it is, I think, rather feeble in view of what precedes it, a sad anticlimax to what was promising to be a fairly arresting sentence. But although that previous clause is much more interesting in every other way, it remains grammatically subordinate: it could not stand on its own.(Richard Palmer, Write in Style: A Guide to Good English, 2nd ed. Routledge, 2002) Types of Subordinating Conjunctions Finite clauses are introduced by a subordinator, which serves to indicate the dependent status of the clause together with its circumstantial meaning. Formally, subordinating conjunctions can be grouped as follows: simple conjunctions: when, whenever, where, wherever, because, if, unless, until, while, as, althoughconjunctive groups: as if, as though, even if, even though, even when, soon after, no soonercomplex conjunctions:: there are three subclasses: (i) derived from verbs . . .: provided (that), granted (that), considering (that), seeing (that), suppose (that), supposing (that), so (that)(ii) containing a noun: in case, in the event that, to the extent that, in spite of the fact that, the day, the way(iii) adverbial: so/as long as, as soon as, so/as far as, much as, now (that) Angela Downing,  English Grammar: A University Course. Routledge, 2006) Subordinate Clauses in Poetry When I heard the learn’d astronomer;When the proofs, the figures, were ranged in columns before me;When I was shown the charts and the diagrams, to add, divide, and measure them;When I, sitting, heard the astronomer, where he lectured with much applause in the lecture-room,How soon, unaccountable, I became tired and sick;Till rising and gliding out, I wander’d off by myself,In the mystical moist night-air, and from time to time,Look’d up in perfect silence at the stars.(Walt Whitman, When I Heard the Learn’d Astronomer. Leaves of Grass)

Vampire Academy Chapter 1 Free Essays

string(50) " I could see the silhouettes of trees and bushes\." ONE I FELT HER FEAR BEFORE I heard her screams. Her nightmare pulsed into me, shaking me out of my own dream, which had had something to do with a beach and some hot guy rubbing suntan oil on me. Images – hers, not mine – tumbled through my mind: fire and blood, the smell of smoke, the twisted metal of a car. We will write a custom essay sample on Vampire Academy Chapter 1 or any similar topic only for you Order Now The pictures wrapped around me, suffocating me, until some rational part of my brain reminded me that this wasn’t my dream. I woke up, strands of long, dark hair sticking to my forehead. Lissa lay in her bed, thrashing and screaming. I bolted out of mine, quickly crossing the few feet that separated us. â€Å"Liss,† I said, shaking her. â€Å"Liss, wake up.† Her screams dropped off, replaced by soft whimpers. â€Å"Andre,† she moaned. â€Å"Oh God.† I helped her sit up. â€Å"Liss, you aren’t there anymore. Wake up.† After a few moments, her eyes fluttered open, and in the dim lighting, I could see a flicker of consciousness start to take over. Her frantic breathing slowed, and she leaned into me, resting her head against my shoulder. I put an arm around her and ran a hand over her hair. â€Å"It’s okay,† I told her gently. â€Å"Everything’s okay.† â€Å"I had that dream.† â€Å"Yeah. I know.† We sat like that for several minutes, not saying anything else. When I felt her emotions calm down, I leaned over to the nightstand between our beds and turned on the lamp. It glowed dimly, but neither of us really needed much to see by. Attracted by the light, our housemate’s cat, Oscar, leapt up onto the sill of the open window. He gave me a wide berth – animals don’t like dhampirs, for whatever reason – but jumped onto the bed and rubbed his head against Lissa, purring softly. Animals didn’t have a problem with Moroi, and they all loved Lissa in particular. Smiling, she scratched his chin, and I felt her calm further. â€Å"When did we last do a feeding?† I asked, studying her face. Her fair skin was paler than usual. Dark circles hung under her eyes, and there was an air of frailty about her. School had been hectic this week, and I couldn’t remember the last time I’d given her blood. â€Å"It’s been like? ­more than two days, hasn’t it? Three? Why didn’t you say anything?† She shrugged and wouldn’t meet my eyes. â€Å"You were busy. I didn’t want to – â€Å" â€Å"Screw that,† I said, shifting into a better position. No wonder she seemed so weak. Oscar, not wanting me any closer, leapt down and returned to the window, where he could watch at a safe distance. â€Å"Come on. Let’s do this.† â€Å"Rose – â€Å" â€Å"Come on. It’ll make you feel better.† I tilted my head and tossed my hair back, baring my neck. I saw her hesitate, but the sight of my neck and what it offered proved too powerful. A hungry expression crossed her face, and her lips parted slightly, exposing the fangs she normally kept hidden while living among humans. Those fangs contrasted oddly with the rest of her features. With her pretty face and pale blond hair, she looked more like an angel than a vampire. As her teeth neared my bare skin, I felt my heart race with a mix of fear and anticipation. I always hated feeling the latter, but it was nothing I could help, a weakness I couldn’t shake. Her fangs bit into me, hard, and I cried out at the brief flare of pain. Then it faded, replaced by a wonderful, golden joy that spread through my body. It was better than any of the times I’d been drunk or high. Better than sex – or so I imagined, since I’d never done it. It was a blanket of pure, refined pleasure, wrapping me up and promising everything would be right in the world. On and on it went. The chemicals in her saliva triggered an endorphin rush, and I lost track of the world, lost track of who I was. Then, regretfully, it was over. It had taken less than a minute. She pulled back, wiping her hand across her lips as she studied me. â€Å"You okay?† â€Å"I? ­yeah.† I lay back on the bed, dizzy from the blood loss. â€Å"I just need to sleep it off. I’m fine.† Her pale, jade-green eyes watched me with concern. She stood up. â€Å"I’m going to get you something to eat.† My protests came awkwardly to my lips, and she left before I could get out a sentence. The buzz from her bite had lessened as soon as she broke the connection, but some of it still lingered in my veins, and I felt a goofy smile cross my lips. Turning my head, I glanced up at Oscar, still sitting in the window. â€Å"You don’t know what you’re missing,† I told him. His attention was on something outside. Hunkering down into a crouch, he puffed out his jet-black fur. His tail started twitching. My smile faded, and I forced myself to sit up. The world spun, and I waited for it to right itself before trying to stand. When I managed it, the dizziness set in again and this time refused to leave. Still, I felt okay enough to stumble to the window and peer out with Oscar. He eyed me warily, scooted over a little, and then returned to whatever had held his attention. A warm breeze – unseasonably warm for a Portland fall – played with my hair as I leaned out. The street was dark and relatively quiet. It was three in the morning, just about the only time a college campus settled down, at least somewhat. The house in which we’d rented a room for the past eight months sat on a residential street with old, mismatched houses. Across the road, a streetlight flickered, nearly ready to burn out. It still cast enough light for me to make out the shapes of cars and buildings. In our own yard, I could see the silhouettes of trees and bushes. You read "Vampire Academy Chapter 1" in category "Essay examples" And a man watching me. I jerked back in surprise. A figure stood by a tree in the yard, about thirty feet away, where he could easily see through the window. He was close enough that I probably could have thrown something and hit him. He was certainly close enough that he could have seen what Lissa and I had just done. The shadows covered him so well that even with my heightened sight, I couldn’t make out any of his features, save for his height. He was tall. Really tall. He stood there for just a moment, barely discernible, and then stepped back, disappearing into the shadows cast by the trees on the far side of the yard. I was pretty sure I saw someone else move nearby and join him before the blackness swallowed them both. Whoever these figures were, Oscar didn’t like them. Not counting me, he usually got along with most people, growing upset only when someone posed an immediate danger. The guy outside hadn’t done anything threatening to Oscar, but the cat had sensed something, something that put him on edge. Something similar to what he always sensed in me. Icy fear raced through me, almost – but not quite – eradicating the lovely bliss of Lissa’s bite. Backing up from the window, I jerked on a pair of jeans that I found on the floor, nearly falling over in the process. Once they were on, I grabbed my coat and Lissa’s, along with our wallets. Shoving my feet into the first shoes I saw, I headed out the door. Downstairs, I found her in the cramped kitchen, rummaging through the refrigerator. One of our housemates, Jeremy, sat at the table, hand on his forehead as he stared sadly at a calculus book. Lissa regarded me with surprise. â€Å"You shouldn’t be up.† â€Å"We have to go. Now.† Her eyes widened, and then a moment later, understanding clicked in. â€Å"Are you? ­really? Are you sure?† I nodded. I couldn’t explain how I knew for sure. I just did. Jeremy watched us curiously. â€Å"What’s wrong?† An idea came to mind. â€Å"Liss, get his car keys.† He looked back and forth between us. â€Å"What are you – â€Å" Lissa unhesitatingly walked over to him. Her fear poured into me through our psychic bond, but there was something else too: her complete faith that I would take care of everything, that we would be safe. Like always, I hoped I was worthy of that kind of trust. She smiled broadly and gazed directly into his eyes. For a moment, Jeremy just stared, still confused, and then I saw the thrall seize him. His eyes glazed over, and he regarded her adoringly. â€Å"We need to borrow your car,† she said in a gentle voice. â€Å"Where are your keys?† He smiled, and I shivered. I had a high resistance to compulsion, but I could still feel its effects when it was directed at another person. That, and I’d been taught my entire life that using it was wrong. Reaching into his pocket, Jeremy handed over a set of keys hanging on a large red key chain. â€Å"Thank you,† said Lissa. â€Å"And where is it parked?† â€Å"Down the street,† he said dreamily. â€Å"At the corner. By Brown.† Four blocks away. â€Å"Thank you,† she repeated, backing up. â€Å"As soon as we leave, I want you to go back to studying. Forget you ever saw us tonight.† He nodded obligingly. I got the impression he would have walked off a cliff for her right then if she’d asked. All humans were susceptible to compulsion, but Jeremy appeared weaker than most. That came in handy right now. â€Å"Come on,† I told her. â€Å"We’ve got to move.† We stepped outside, heading toward the corner he’d named. I was still dizzy from the bite and kept stumbling, unable to move as quickly as I wanted. Lissa had to catch hold of me a few times to stop me from falling. All the time, that anxiety rushed into me from her mind. I tried my best to ignore it; I had my own fears to deal with. â€Å"Rose? ­what are we going to do if they catch us?† she whispered. â€Å"They won’t,† I said fiercely. â€Å"I won’t let them.† â€Å"But if they’ve found us – â€Å" â€Å"They found us before. They didn’t catch us then. We’ll just drive over to the train station and go to L.A. They’ll lose the trail.† I made it sound simple. I always did, even though there was nothing simple about being on the run from the people we’d grown up with. We’d been doing it for two years, hiding wherever we could and just trying to finish high school. Our senior year had just started, and living on a college campus had seemed safe. We were so close to freedom. She said nothing more, and I felt her faith in me surge up once more. This was the way it had always been between us. I was the one who took action, who made sure things happened – sometimes recklessly so. She was the more reasonable one, the one who thought things out and researched them extensively before acting. Both styles had their uses, but at the moment, recklessness was called for. We didn’t have time to hesitate. Lissa and I had been best friends ever since kindergarten, when our teacher had paired us together for writing lessons. Forcing five-year-olds to spell Vasilisa Dragomir and Rosemarie Hathaway was beyond cruel, and we’d – or rather, I’d – responded appropriately. I’d chucked my book at our teacher and called her a fascist bastard. I hadn’t known what those words meant, but I’d known how to hit a moving target. Lissa and I had been inseparable ever since. â€Å"Do you hear that?† she asked suddenly. It took me a few seconds to pick up what her sharper senses already had. Footsteps, moving fast. I grimaced. We had two more blocks to go. â€Å"We’ve got to run for it,† I said, catching hold of her arm. â€Å"But you can’t – â€Å" â€Å"Run.† It took every ounce of my willpower not to pass out on the sidewalk. My body didn’t want to run after losing blood or while still metabolizing the effects of her saliva. But I ordered my muscles to stop their bitching and clung to Lissa as our feet pounded against the concrete. Normally I could have outrun her without any extra effort – particularly since she was barefoot – but tonight, she was all that held me upright. The pursuing footsteps grew louder, closer. Black stars danced before my eyes. Ahead of us, I could make out Jeremy’s green Honda. Oh God, if we could just make it – Ten feet from the car, a man stepped directly into our path. We came to a screeching halt, and I jerked Lissa back by her arm. It was him, the guy I’d seen across the street watching me. He was older than us, maybe mid-twenties, and as tall as I’d figured, probably six-six or six-seven. And under different circumstances – say, when he wasn’t holding up our desperate escape – I would have thought he was hot. Shoulder-length brown hair, tied back in a short ponytail. Dark brown eyes. A long brown coat-a duster, I thought it was called. But his hotness was irrelevant now. He was only an obstacle keeping Lissa and me away from the car and our freedom. The footsteps behind us slowed, and I knew our pursuers had caught up. Off to the sides, I detected more movement, more people closing in. God. They’d sent almost a dozen guardians to retrieve us. I couldn’t believe it. The queen herself didn’t travel with that many. Panicked and not entirely in control of my higher reasoning, I acted out of instinct. I pressed up to Lissa, keeping her behind me and away from the man who appeared to be the leader. â€Å"Leave her alone,† I growled. â€Å"Don’t touch her.† His face was unreadable, but he held out his hands in what was apparently supposed to be some sort of calming gesture, like I was a rabid animal he was planning to sedate. â€Å"I’m not going to – â€Å" He took a step forward. Too close. I attacked him, leaping out in an offensive maneuver I hadn’t used in two years, not since Lissa and I had run away. The move was stupid, another reaction born of instinct and fear. And it was hopeless. He was a skilled guardian, not a novice who hadn’t finished his training. He also wasn’t weak and on the verge of passing out. And man, was he fast. I’d forgotten how fast guardians could be, how they could move and strike like cobras. He knocked me off as though brushing away a fly, and his hands slammed into me and sent me backwards. I don’t think he meant to strike that hard – probably just intended to keep me away – but my lack of coordination interfered with my ability to respond. Unable to catch my footing, I started to fall, heading straight toward the sidewalk at a twisted angle, hip-first. It was going to hurt. A lot. Only it didn’t. Just as quickly as he’d blocked me, the man reached out and caught my arm, keeping me upright. When I’d steadied myself, I noticed he was staring at me – or, more precisely, at my neck. Still disoriented, I didn’t get it right away. Then, slowly, my free hand reached up to the side of my throat and lightly touched the wound Lissa had made earlier. When I pulled my fingers back, I saw slick, dark blood on my skin. Embarrassed, I shook my hair so that it fell forward around my face. My hair was thick and long and completely covered my neck. I’d grown it out for precisely this reason. The guy’s dark eyes lingered on the now-covered bite a moment longer and then met mine. I returned his look defiantly and quickly jerked out of his hold. He let me go, though I knew he could have restrained me all night if he’d wanted. Fighting the nauseating dizziness, I backed toward Lissa again, bracing myself for another attack. Suddenly, her hand caught hold of mine. â€Å"Rose,† she said quietly. â€Å"Don’t.† Her words had no effect on me at first, but calming thoughts gradually began to settle in my mind, coming across through the bond. It wasn’t exactly compulsion – she wouldn’t use that on me – but it was effectual, as was the fact that we were hopelessly outnumbered and outclassed. Even I knew struggling would be pointless. The tension left my body, and I sagged in defeat. Sensing my resignation, the man stepped forward, turning his attention to Lissa. His face was calm. He swept her a bow and managed to look graceful doing it, which surprised me considering his height. â€Å"My name is Dimitri Belikov,† he said. I could hear a faint Russian accent. â€Å"I’ve come to take you back to St. Vladimir’s Academy, Princess.† How to cite Vampire Academy Chapter 1, Essay examples

Number Stairs Essay Example

Number Stairs Essay Part 1: To investigate the relationship between the stair total and the position of the stair shape on the grid, for other 3-step stairs. The number in the bottom left corner of the stair shape labels the position of the stair shape. The aim of this part of the investigation is to find a formula to work out the s-total (stair total) by knowing the s-number (stair number).45353625262725 + 26 + 27 + 35 + 36 + 45 = 194s-number = 25s-total = 1942111121231 + 2 + 3 + 11 + 12 + 21 = 50s-number = 1s-total = 502212132342 + 3 + 4 + 12 + 13 + 22 = 56s-number = 2s-total = 562313143453 + 4 + 5 + 13 + 14 + 23 = 62s-number = 3s-total = 622414154564 + 5 + 6 + 14 + 15 + 24 = 68s-number = 4s-total = 68Another observation here is that in each column of the stair shape, the difference between these rows of numbers in the same column, is 10. (Apart from the last column, which only consists of 1 number.) The difference between these numbers is 10 because in the grid, each row contains 10 numbers.Table of Results:s-numbers-total150+ 6256+ 632+ 646825194To go from one term to the next, simply add 6 each time. However, this does not show the relationship between the s-number and the s-total. This sequence (adding/subtracting a number each time), is known as an arithmetic sequence. A formula to find out the relationship between the s-number and the s-total is: first term + common difference x ( n 1 ). The first term here is 50, and the common difference is 6.50 + 6(n 1)= 50 + 6n 6= 6n + 442515165675 + 6 + 7 + 15 + 16 + 25 = 74(6 x 5) + 44 = 74s-number = 5s-total = 742616176786 + 7 + 8 + 16 + 17 + 26 = 80(6 x 6) + 44 = 80s-number = 6s-total = 8046363726272826 + 27 + 28 + 36 + 37 + 46 = 200(6 x 26) + 44 = 200s-number = 26s-total = 200After testing the formula to see if it works, a proof must be presented to show that it works for any s-number (with a few exceptions see Conclusion). If the s-number is represented as n:nAs mentioned in the aim, the bottom left corner square is the s-num ber (or in this example, known as nnn + 1n + 2Because the numbers in the grid increases by 1 each time, I can say that the two numbers, in the same row, increases by 1, thus the diagram; n + 1 and n + 2.n+20n+10nn + 1n + 2As mentioned previously, the numbers in the same column have a difference of 10. Thus, n + 10 and n + 20 as shown in the diagram. I can then show: (v)n+20n+10nn + 1n + 2If I add all these values (inside the squares) together:n + (n + 1) + (n + 2) + (n + 10) + (n + 11) + (n + 20)= 6n + 44*Proof 1: Note that there are 6 ns in this equation, because there are 6 squares.Thus, I have proven that my formula 6n + 44 works for every stair shape in that grid size. I can carry this investigation further by investigating the relationship between the stair totals on other number grids.Part 2: To further investigate the relationship between the stair totals and other step stairs on other number grids. I have decided to investigate the relationship between the stair totals on ot her number grids when the s-number stays constant because it will be easier to observe the relationship between the s-grid (stair number grid) and the s-total.7451231 + 2 + 3 + 4 + 5 + 7 = 22s-grid = 3s-total = 229561231 + 2 + 3 + 5 + 6 + 9 = 26s-grid = 4s-total = 2611671231 + 2 + 3 + 6 + 7 + 11 = 30s-grid = 5s-total = 3013781231 + 2 + 3 + 7 + 8 + 13 = 34s-grid = 6s-total = 34Table of Results:s-grids-total322+ 4436+ 4530+46341050In the table, it shows that the s-total increases by 4 each time as the s-grid increases by 1. (When g = grid size,) this is because:n+2gn + gn+g+1nn + 1n + 2; Previously, I noticed that the difference between each row in the same column is the grid size.n + (n + 1) + (n + 2) + (n + g) + (n + g + 1) + (n + 2g)= 6n + 4g + (4)**Note: 6n + 4g because there are 4gs in the formula (as shown above).Now that I have found out the relationship between the s-number, s-grid, and the s-total, I can carry this investigation further by investigating the relationship betw een the other step stairs, s-number, s-grid, and s-totals.I will investigate the relationship between the s-number, s-total, s-grid and s-shape (stair shape). The s-shape will be investigated by enlargement; 1 square increase in length, and 1 square increase in width.nThe s-number remains at the bottom left corner of the stair shape. Instead of 6 squares, there are 10. Based on my previous observations, I can predict the relationship between this s-shape, the s-number, s-grid, and the s-total as: 10n + 10g + 10.I can check my prediction:n+3gn+2gn+2g+1n+gn+g+1n+g+2nn+1n+2n+3n+(n+1)+(n+2)+(n+3)+(n+g)+(n+g+1)+(n+g+2)+(n+2g)+(n+2g+1)+(n+3g)= 10n + 10g + 10I shall investigate the next stair shape, which will have a height of 5 squares, and a width of 5 squares, a total of 15 squares.n+4gn+3gn+3g+1n+2gn+2g+1n+2g+2n+gn+g+1n+g+2n+g+3nn+1n+2n+3n+4n+(n+1)+(n+2)+(n+3)+(n+4)+(n+g+)+(n+g+1)+(n+g+2)+(n+g+3)+(n+2g)+(n+2g+a)+(n+2g+2)+(n+3g)+(n+3g+1)+(n+4g)= 15n + 20g + 20Observation: I have noticed that the number of squares in each stair shape has a link with triangle numbers. For example: a triangle number sequence is as follows:When the stair shape size was 3, it has 6 squares. When the stair shape size was 4, it has 10 squares, and when the stair shape size was 5, it has 15 squares. Just like the diagram on the previous page, the pattern for the stair shape size is the same pattern as triangle numbers. This is because the stair shape is a triangle:s-sizeno. of squares23+ 336+ 4410+ 5515+ 6621I can predict the number of squares they are for any s-size, following the triangle number sequence.The formula for the triangle number sequence is:(Where s is the s-size.)I should test this formula to check if it works. I shall try it on an s-size of 7.7+ 6+ 5+ 4+ 3+ 2+ 1Number of squares in this diagram: 28Since I have successfully tested out that the relationship between the s-size and the number of squares in that s-size is the same as triangle number sequence; thus the formula to work out the s-total when the s-number, s-grid, and s-size is known, can be currently worked out as:s-total = (Note: X is the unknown)In this case, I have used the Xs twice, only because they are of equal value. By putting the s-size value and the formula in a table, I could see why I used the Xs twice in the formula.s-sizeformula36n + 4g + 4410n + 10g + 10515n + 20g + 20The co-efficient has the same value as the constant.I then needed to find to how to find out the co-efficient and the constant. Because there doesnt seem to have a constant difference between the co-efficient, I shall use the method changing differences to find the formula for the co-efficient. There is a formula to find the changing difference known as the Gregory Newton Formula.Firstly, I would need to find the value of the co-efficient when the s-size is 0. Obviously, if the s-size is 0, the s-total will be 0, as there are no squares to add up its value. To show how I worked out the difference in order to use th e Gregory Newton Formula, I made a table of differences:s-sizeX1st Difference2nd Difference3rd Difference4th Difference00+ 010+ 1+ 1+ 121+ 2+ 0+ 3+ 134+ 3+ 0+ 6+ 1410+ 4+ 10520After producing the table of differences, I was able to carry out the Gregory Newton Formula and found out how to find X:However, I must test this formula to see if it works. I shall test it out on an s-size of 6.n+5gn+4gn+4g+1n+3gn+3g+1n+3g+2n+2gn+2g+1n+2g+2n+2g+3n+gn+g+1n+g+2n+g+3n+g+4nn+1n+2n+3n+4n+5n+(n+1)+(n+2)+(n+3)+(n+4)+(n+5)+(n+g)+(n+g+1)+(n+g+2)+(n+g+3)+(n+g+4)+(n+2g)+(n+2g+1)+(n+2g+2)+(n+2g+3)+(n+3g)+(n+3g+1)+(n+3g+2)+(n+4g)+(n+4g+1)+(n+5g)= 21n + 35g + 35It appears that this section of the formula works. Now the new current formula is:s-total =Important: However, this formula has its limitations. For example, the step stair may be placed on a certain area that causes the step stair to be off the grid. This means that the formula cannot calculate the s-total as there are no numbers off the grid. Per haps another limitation can be found if it cannot calculate negative numbers.I shall test it out on an s-size of 7, s-grid of 8, and the s-number is 20.6860615253544445464736373839402829303132332021222324252620 + 21 + 22 + 23 + 24 + 25 + 26 + 28 + 29 + 30 + 31 + 32 + 33 + 36 + 37 + 38 + 39 + 40 + 44 + 45 + 46 + 47 + 52 + 53 + 54 + 60 + 61 + 68= 1064Now to test the formula out on negative numbers:1314151617187891011121234560-1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17(-12)+(-13)+(-14)+(-6)+(-7)+(0)= -52It appears that negative numbers do not work with this formula, thus the formula is limited to positive integers and that the stair shape must not have any part of it exceeding the grid. However, the formula works excluding the limitations. In conclusion, the relationship between the s-number, s-grid, s-size, and s-total is:s-total =(With certain restrictions as mentioned above)However, this formula can be simplified because as previously mentioned, the Xs were in 2 parts of the formula, thus it can be simplified. The first part of the equation where the formula for triangle number lies, can also be simplified to:An extention of this investigation, could be to investigate the relationship between negative numbers, or transformation of the stair shape.

Abortion is a right choice. essays

Abortion is a right choice. essays We live in a nation built on the idea of freedom, freedom of choice and freedom of expression, yet we are not free. After all, different people have different attitudes toward abortion. Like wise, the oppositions of society create constricts for women seeking abortions. They maintain that since the unborn child in the womb is a human life, abortion is a kind of guilt, which deprives of a human right to life. Certainly, they go on to point out that abortion should be banned by the law in order to protect these human lives. Of course, the main questions that everyone must face are which areas of behavior to leave to private choice and which to regulate in the interest of virtuous. However, abortion is a very serious and complex issue. This issue will not just end with laws. Therefore, the fact of the conflict is not being concern of its legal status abortion is still going to exist. Notably, still have women who are going to seek them with the help of men to arrange them. Moreover, wit h the doctors and some not qualified who will still perform them. It cannot be denied, this is reality because before 1973 a lot of women died from illegal abortions. Currently, abortion is legal, however, if histories were to repeat itself, and abortions are considered illegal once again, the results would be appalling. Not only would women turn to insalubrious secretive abortions and self induced abortions, the psychological pain and scars would be considerably more awful than those of a legal abortion. In a word, every woman is permitted to the right of privacy in dealing with her own body if women are to be denied this right, history will repeat itself jeopardizing the lives of millions of women. Formerly, legalizing abortion will guide women to have safe conditions, with qualified doctors and proper care. By the same reason, if abortions were no longer an option, womens health issues would arise. Even though, the government will still be able to ...

Using the PHP Rand() Functions to Generate Random Numbers

Using the PHP Rand() Functions to Generate Random Numbers The rand() function is used in PHP to generate a random integer. The rand() PHP function can also be used to generate a random number within a specific range, such as a number between 10 and 30. If no max limit is specified when using the rand() PHP function, the largest integer that can be returned is determined by the getrandmax() function, which varies by operating system.   For example, in Windows, the largest number that can be generated is 32768. However, you can set a specific range to include higher numbers. Rand() Syntax and Examples The correct syntax for using the rand PHP function is as follows: rand(); or rand(min,max); Using the syntax as described above, we can make three examples for the rand() function in PHP: ?phpecho (rand(10, 30) . br);echo (rand(1, 1000000) . br);echo (rand());? As you can see in these examples, the first rand function generates a random number between 10 and 30, the second between 1 and 1 million, and then third without any maximum or minimum number defined. These are some possible results: 20442549830380191 Security Concerns Using Rand() Function The random numbers generated by this function are not cryptographically secure values, and they should not be used for cryptographic  reasons. If you need secure values, use other random functions such as random_int(), openssl_random_pseudo_bytes(), or random_bytes() Note: Beginning with PHP 7.1.0, the rand() PHP function is an alias of mt_rand(). The mt_rand() function is said to be four times faster and it produces a better random value. However, the numbers it generates are not cryptographically secure. The PHP manual recommends using the  random_bytes() function for cryptographically secure integers.

Pride and Prejudice Essay Example | Topics and Well Written Essays - 1000 words

Pride and Prejudice - Essay Example Elizabeth had asserted her love, and her experience can also be useful for women today. Austen's use of irony in her novel offers important insights to her attitude about life through the experiences of her characters. This paper will discuss what Jane Austen had to say about women, class mobility, and marriage based in the experiences of Elizabeth Bennet in Pride and Prejudice. In addition to that, the nature of Elizabeth Bennet's experience and lessons she "learned" from it will be estimated. The experience of women today and that of Elizabeth Bennet will be analyzed, as well as the reasons of Elizabeth Bennet's experience relevance for women position in our days. 2. Elizabeth Bennet is one of the main protagonists in Austen's Pride and Prejudice. Her experience in the novel is largely influenced by her nature and her personality, as well as appropriate traits of her character which allowed her to win her real love and destiny. Elizabeth is the second daughter in the family of the Bennets and the most clever and intelligent among them. Her positive traits allowed her to resist current bourgeois norms and traditions and to be higher than these norms. Mr Darcy noticed her charm and evaluated her as a woman who had interesting and unique individuality, but at their first meet they didn't had any romantic feelings towards each other - so, first impression can be not true. Darcy said that "She is tolerable, but not so handsome enough to tempt me; I am in no humour at present to give consequence to young ladies who are slighted by other men" (Chapter 3, p.7). It happened because of Elizabeth Bennet's pride and Darcy's prejudice about her social bac kground. So, in that moment Jane Austen depicted about the common social norms which were spread between men and women in that time, and those norms often asserted women to marry men who would provide high social status for their future wives. There are some characters in the novel who made different obstacles towards the relationships development between Elizabeth and Darcy, such as Mrs Bennet, Lady Catherine, Miss Bingley and Wickham, and the motifs which these people followed interfered to romantic relationships between Elizabeth and Darcy. Lady Catherine tried to control Darcy who was her nephew, Mrs Bennet tried to get married her daughters, including Elizabeth, by all means, and it led to numerous foolishness displayed by Mrs Bennet. Wickham deceived Elizabeth telling her that Darcy had taken his money, and that caused her mistrust to Darcy: "How abominable! I wonder that the very pride of this Mr. Darcy has not made him just to you! If from no better motive, that he should no t have been too proud to be dishonest - for dishonesty I must call it" (Chapter 16, p.60). So, Austen has showed that there are many obstacles for people who love each other to be together, and that there are some women whose motifs for marriage are not love but social class advantages. The author tried to show that love and true affections of those who really love each other are able to be higher than any obstacles. But the author also showed that social class and aspiration towards money and success can be a basis for marriage for
