Self Reliance Essays - Eddic Poetry, Lokasenna,

Independence There is a period in each man's instruction when he shows up at the conviction that jealousy is obliviousness; that impersonation is self destruction; that he should take himself for better, in negative ways, as his bit; that however the wide universe is brimming with great, no part of supporting corn can come to him however through his drudge offered on that plot of ground which is given to him to work. The force which lives in him is new in nature, and none however he recognizes what that is which he can do, nor does he know until he has attempted. Not in vain one face, one character, one reality, establishes a lot of connection with him, and another none. This model in the memory isn't without preestablished agreement. The eye was set where one beam should fall, that it may affirm of that specific beam. We however half communicate, and are embarrassed about that divine thought which every one of us speaks to. It might be securely trusted as proportionate and of good issues, so it be dependably granted, yet God won't have his work made show by defeatists. A man is calmed and gay at the point when he has placed his heart into his work and given a valiant effort; in any case, what he has said or done something else, will give him no harmony. It is a redemption which doesn't convey. In the endeavor his virtuoso abandons him; no dream becomes friends with; no creation, no expectation. Confide in thyself: each heart vibrates to that iron string. Acknowledge the spot the heavenly provision has found for you, the general public of your peers, the association of occasions. Incredible men have consistently done as such, and trusted themselves honest to the virtuoso of their age, deceiving their recognition that the completely reliable was situated at their heart, working through their hands, prevailing in all their being. What's more, we are presently men, and must acknowledge in the most elevated brain the equivalent extraordinary predetermination; and not minors and invalids in a secured corner, not weaklings escaping before an upheaval, yet aides, deliverers, and sponsors, complying with the Almighty exertion, and progressing on Bedlam and the Dark. What beautiful prophets nature yields us on this content, in the face and conduct of youngsters, angels, and even savages! That partitioned and rebel mind, that doubt of a supposition since our number juggling has processed the quality and means restricted to our motivation, these have not. Their brain being entire, their eye is so far unconquered, and when we look in their faces, we are perplexed. Outset adjusts to no one: all fit in with it, so one darling normally makes four or five out of the grown-ups who babble and play to it. So God has furnished youth and pubescence and masculinity no less with its own intrigue and enchant, and made it fortunate and generous and its cases not to be put by, on the off potential for success that it will have without anyone else. Try not to think the young has no power, since he can't address you and me. Look! in the following room his voice is adequately unmistakable and determined. It appears he knows step by step instructions to address his peers. Timid or strong, at that point, he will realize how to make us seniors extremely pointless. The disregard of young men who make certain of a supper, and would scorn as much as a ruler to do or say nothing to assuage one, is the solid mentality of human instinct. A kid is in the parlor what the pit is in the playhouse; autonomous, flippant, watching out from his corner on such individuals what's more, realities as cruise by, he attempts and sentences them on their merits, in the quick, synopsis method of young men, as great, awful, fascinating, senseless, smooth, irksome. He cumbers himself never about outcomes, about interests: he gives a free, authentic decision. You should court him: he doesn't court you. Yet, the man is, in a manner of speaking, applauded into prison by his cognizance. When he has once acted or spoken with eclat, he is a dedicated individual, viewed by the compassion or the contempt of hundreds, whose expressions of love should now go into his record. There is no Lethe for this. Ok, that he could pass again into his lack of bias! Who would thus be able to dodge all vows, and having watched, watch again from the equivalent unaffected, impartial, unbribable, unaffrighted guiltlessness, should consistently be considerable. He would articulate conclusions on every single passing undertaking, which supposedly being not private, yet fundamental, would sink like darts into the ear of men, and put them in dread. These are the voices which we hear in isolation, yet they develop black out and quiet as we go into the

Genetic Engineering Essay - 993 Words

Genetic Engineering There are many manipulations that humans have done to the environment throughout history in order to benefit mankind. As technology has increased many of these manipulations have begun to take place on a larger scale resulting in more drastic changes to the environment. The first manipulations humans used to benefit themselves were farming and domestication of animals. This was very basic manipulation to the environment and did not make drastic changes to the environment. It was not until the industrial revolution that pollution and people’s negative effects on the environment became very apparent. New technology allowed for people to make changes that could possibly be irreversible upon the environment. With†¦show more content†¦Other methods of Cloning up until Dolly used cloning by splitting embryos to create twins, or using artificial insemination. One of the downsides to cloning using this method is that the clones begin to age a lot faster making it impossible t o repeat the process by making clones of clones of clones and so on. The problem arises that because there is less of a DNA strand passed on through the aged clones, the clones become more susceptible to mutation. Another negative effect of cloning is the prevention of evolution, in particular the immune system. Through sexual reproduction the evolved immune system is inherited by the offspring. Clones don’t get that new immune system. This makes clones susceptible to the same germs of the previous generation. Without sex we’d soon be toast for germs. And cloned, genetically identical cows would be sitting ducks for epidemics. (Rantala, 189) Biological warfare is one of the obviously negative effects of genetic engineering. By manipulating bacteria or viruses, a biologist can turn relatively harmless virus such as the flu into a deadly virus. If one of these altered viruses is to be released into the public, the consequences could be hundreds of times worse than the plagues that have affected humans throughout history.

How Successful Were Wolseys Domestic Policies - 1400 Words

How successful were Wolsey’s domestic policies? Law One area that Wolsey did try to reform was England’s legal system. England mainly used common law at that time however civil law was seen as more modern and was favored in southern Europe. Civil law was used in the King’s council when it acted as a court of law. As Lord Chancellor Wolsey had oversight over the legal system in England. The law awakened Wolsey’s intellectual interest. He was a judge in the Chancery Court and handled disputes over wills, contracts and property. He had successfully reformed the Star Chamber where he was determined to get rid of corruption. He made it much fairer, cheaper and more efficient and was not afraid to take on the powerful. He had the Earl of†¦show more content†¦This was because most of the people that were responsible for the enclosures were rich landowners and were also MP’s. Also in 1523 money was needed for war against France so he needed parliaments support and he made a deal with Parliament to drop the investigation in return for a Parliamentary subsidy. In 1526 Wolsey tried to reintroduce his policy after the disruption caused by the amicable grant but declarations ordering the removal of enclosures were ignored by landowners. Overall I think that Wolsey was mostly unsuccessful although he did order the rebuilding of houses and the returning of land to arable farming but the landowners just ignored this and continued with the enclosures. He was also forced to accept all existing enclosures which meant that he had failed. Finances The problem that Wolsey faces was that the parliament taxes which was fifteenths and tenths did not produce enough income for what Henry VIII wanted like war. It was expected that the king would be able to finance his living from his own income, but provision was made for additional money for war and its cost this was called fifteenths and tenths. This parliamentary tax grant was for special occasions like war. These were fixed rates that were paid by towns and boroughs but it was not enough for what Henry wanted. Wolsey was frequently under pressure to increase the crown’s income. Wolsey had found a solution to the problem when he introduced a new parliamentary tax called the Subsidy.Show MoreRelatedDomestic Policy Under Cardinal Thomas Wolsey Was a Failure How Far Do You Agree with This Statement?2564 Words   |  11 Pages‘Domestic policy under Wolsey was a failure’.

Causes of the Venezuella Refinery Complex Fire Incident Essay Sample free essay sample

The Paraguana Refinery Complex was state-owned by the Petroleos de Venezuela. S. A. ( PDVSA ) . PDVSA has long been criticized for their carelessness in industrial safety. Since 2003. PDVSA has been plagued by 79 accidents which include 6 detonations and 7 fires within the refinery composite. Despite these incidents. no major safety steps were undertaken by the company. This makes the safety criterions of PDVSA questionable. As a consequence. the carelessness of safety protocols by the PDVSA is the root cause of the Amuay refinery detonation. Lack of Maintenance In PDVSA’s 2011 study. it was found that seven out of the nine major care undertakings scheduled for Amuay had been postponed due to losing replacing parts. The continuance of unscheduled downtime therefore increased. The deficiency of care could hold besides resulted in failure of safety devices ( i. e. safety interlock system. safety valves ) .

The Effect of Video Games on Children free essay sample

The effects of videogames on children Today in the world there are many options and ways to entertain children. There are football clubs, movies, television programs, and video games. But there are many activities that are not good for children, who have ill effects on your subconscious and in the way they operate. We know that violence on television has bad effects on children. Psychologists say that there is a correlation between the aggressiveness and violence on television is as strong as the effects of smoking on your lungs. Are the effects of violence in video games as strong as the attack on television? Psychologists say that children who play violent video games are affected by violent thoughts and feelings after playing. Video games were invented in the 70s, and from there, to date, games have become very popular. Children who have between two and eighteen play video games for more than an hour each day.

These data are increasing continuously. I doubt the inventors have provided the numbers of violent games and their effects for children. In the 90s violent video games like Mortal Kombat and Street Fighter were released to the public. Now violent games like Halo, Quake, Vice City, San Andreas, Def Jam and others are top sellers, Xbox, Xbox 360 PlayStation 1, 2, 3, and staff, the Gameboy Advance and the computer include equipment consoles and games played by children. 49% of girls and 73% of children say their favorite games are violent. For many people, television and video games take away the child caught his inventiveness, he hurt his concentration and therefore their ability to learn. Furthermore it has been believed in doing sedentary activities that have serious consequences for growth, and that when audiovisual equipment damage a childs vision. Surely all these hours in front of the games have an effect on children. Craig Anderson and Douglas Gentile show that games can have a stronger effect on childrens aggression that movies and television because: 1) the games are very committed, 2) games produce violent behavior 3) children repeat these behaviors much during the game. According to psychologists, there is a significant positive correlation. Accordin to Anderson and Brad Bushman, exposure to violent video games for a short time causes a temporary increase in aggression. These games increase aggression increase through the thoughts, feelings, and aggressive actions. It was also shown that video games affect the mechanisms that control the development of an aggressive personality or aggressive behavior. Anderson has shown, that the aggressive effects occur in children who do not have an aggressive personality as much as in those with an aggressive personality. I think that these games are bad for the health and behavior of children, which make this an addiction or a fiction all the time and are thinking about that game and violent images that project there, and disrupt their concentration at all times, we must stop this situation, prohibiting children not involved with these games, so we have good people in our culture and stand as a united country, know how many hours children spend playing these teens and games-thousands of hours-but if we substitute the games of war and violence for a teaching and learning, we train men and women well prepared and ready for life. Besides being close to the TV or monitor to play and to be following the action of the game, agility ocular is streamlined, but this causes a great visual fatigue. In the hands, for example, can develop carpal tunnel tenditis or diseases of muscle type and also hearing, posture, tension muscle and even high blood pressure. Tips: * Be interested in the activities of your child after school. Make an effort to share at least 20 minutes a day with him and that time as enjoyable and educational as possible. Be careful not to waste your life behind a computer or watching television programs unsuitable for their age. * Try to spend your free time in constructive activities that promote the culture, socialization, education and fun or playing sports. * Select the video games that acquires according to the level of your childs development and content of the game, preferring that can provide educational, rather than those that only produce violence and aggression. In conclusion, violent video games have a bad effect on the subconscious of children and this effect is reflected in their aggressive behavior. The number of violent games is growing, leading to an increase in aggressive people in our culture. Something needs to change, because the effects will be very negative society also affects your health also, because it is creating visual problems, hearing of the spine and hands, but if the change for a few good people in education will train health and well prepared for life, and will form a better world in which to live, away from bad habits and tricks

Investigating a Sequence of Numbers Essay Example

Investigating a Sequence of Numbers Essay Example Investigating a Sequence of Numbers Essay Investigating a Sequence of Numbers Essay In this Mathematics Portfolio, I am going to investigate a sequence of numbers by mathematical methods which I have learnt in the I.B. Mathematics HL course. Throughout the investigation, I will include all my workings in order to let examiners know exactly how I come up with the answers. A sequence is a set of numbers with a definite order. A series is a sum of a sequence. The sequence of numbers {an}?n =1 is: 1 x 1!, 2 x 2!, 3 x 3!, The two signs outside the bracket of an represent the range of the sequence. The bottom one is where the sequence begins and the one above is where it should end. Since it is stated the sequence starts from n = 1, therefore the first term, a1 = 1 x 1!, the second term, a2 = 2 x 2! and the third term, a3 = 3 x 3! The ! sign after the numbers is called a factorial notation. The notation basically means the product of all the numbers from 1 to the number with the notation. For example: 3! = 1 x 2 x 3 = 6 5! = 1 x 2 x 3 x 4 x 5 = 120 ? n! = 1 x 2 x 3 x 4 x x n 2! x 3 = 1 x 2 x 3 = 3! = 6 ? n! x (n + 1) = (n + 1)! Going back to the investigation, to find the nth term of the sequence, the steps are shown below: a1 = 1 x 1! = 1 a2 = 2 x 2! = 2 x 1 x 2 = 4 a3 = 3 x 3! = 3 x 1 x 2 x 3 = 18 a4 = 4 x 4! = 4 x 1 x 2 x 3 x 4= 96 . . . ? an = n x n! This is because looking at the sequence, I noticed that there is a similarity in each term. For an, when n = 1, the calculation will be 1 x 1!; when n = 2, the calculation will be 2 x 2!. Therefore from this pattern, the formula to find the nth term is: an = n x n! Let Sn = a1 + a2 + a3 + a4 + + an The term Sn means the summation of all the numbers in the sequence from the first term to the nth term. The mathematical explanation is shown above. For example, a sequence of numbers is 1,2,3,4,5,6,. S1 = 1 S2 = 1 + 2 = 3 S6 = 1 + 2 + 3 + 4 + 5 + 6 = 21 In the sequence that I am investigating, I am told to find Sn for different values of n: S1 = a1 = 1 x 1! = 1 S2 = a1 + a2 = 1 x 1! + 2 x 2! = 1 + 4 = 5 S3 = a1 + a2 + a3 = 1 x 1! + 2 x 2! + 3 x 3! = 1 + 4 + 18 = 23 S4 = a1 + a2 + a3 + a4 = 1 x 1! + 2 x 2! + 3 x 3! + 4 x 4! = 1 + 4 + 18 + 96 = 119 S7 = a1 + a2 + a3 + a4 + a5 + a6 + a7 = 1 x 1! + 2 x 2! + 3 x 3! + 4 x 4! + 5 x 5! + 6 x 6! + 7 x 7! = 1 + 4 + 18 + 96 + 600 + 4320 + 35280 = 40319 By using the information above, I will try to conjecture an expression for Sn. I am going to put all the datas on a table to see if there is any significant discovery. n 1 2 3 4 5 6 an 1 4 18 96 600 4320 Sn 1 5 23 119 719 5039 n! 1 2 6 24 120 720 From the table, I noticed that an is always the difference between n! and (n + 1)! The mathematical expression is: an = (n + 1)! n! Since (n + 1)! seems useful for the investigation, I did another table too: n 1 2 3 4 5 6 (n + 1)! 2 6 24 120 720 5040 Sn 1 5 23 119 719 5039 Looking at the row of (n + 1)! and Sn, there is a constant difference of 1 between them. Therefore I added the row of Sn to the second table (in black). When n = 1, (n + 1)! = 2 ; Sn = 1 n = 2, (n + 1)! = 6 ; Sn = 5 . . . n = 6, (n + 1)! = 5040; Sn = 5039 According to what I have discovered, Sn can be express mathematically in this way: Sn = 1 x 1! + 2 x 2! + 3 x 3! + + n x n! = (n + 1)! 1 To prove that my expression is right, I am using mathematical induction to verify the given result: Pn : 1 x 1! + 2 x 2! + 3 x 3! + + n x n! = (n + 1)! 1 Pk : 1 x 1! + 2 x 2! + 3 x 3! + + k x k! = (k + 1)! 1 If Pk+1 is true the result should be (k + 1 + 1)! 1 = (k + 2)! 1 Pk+1 : 1 x 1! + 2 x 2! + 3 x 3! + + k x k! + (k + 1) x (k + 1)! = (k + 1)! 1 + (k + 1) x (k + 1)! = (k + 1)! [(k + 1) + 1] 1 = (k + 1)! (k + 2) 1 = (k + 2)! 1 ? Pk+1 is true. P1 : LHS = 1 x 1! = 1 RHS = (1 + 1)! 1 = 1 ? P1 is true. ? Pn is true for all positive integers n. Already I have derived the formula an = (n + 1)! n! from the first table. But there is still another way to derive it just from the original formula: an = n x n! = (n + 1 1) x n! = (n + 1) x n! n! = (n + 1)! n! Sn = a1 + a2 + a3 + a4 + a5 + + an = (1 + 1)! 1! + (2 + 1)! 2! + (3 + 1)! 3! + (4 + 1)! 4! + (5 + 1)! 5! + + (n + 1)! n! = 2! 1! + 3! 2! + 4! 3! + 5! 4! + 6! 5! + + (n + 1)! n! At this step, I can see that many numbers cancel out each other except (-1) and (n + 1)! as it goes on to the last term: = -1! + (n + 1)! = (n + 1)! 1 Alternatively, I have used another method to prove of my conjecture for Sn: Sn = 1 x 1! + 2 x 2! + 3 x 3! + + n x n! = (n + 1)! 1 Let cn = an + an+1 According to what I have done before, an = (n + 1)! n! ? cn = (n + 1)! n! + (n + 1 + 1)! (n + 1)! = (n + 1)! n! + (n + 2)! (n + 1)! = (n + 2)! n! To simplify it: cn = (n + 2)! n! = (n + 2) (n + 1) (n!) n! = n! [(n + 2) (n + 1) 1] = n! (n2 + 2n + n + 2 1) = n! (n2 + 3n + 1) Tn = c1 + c2 + c3 + c4 + c5 + + cn To investigate Tn for different values of n, a table is drawn below showing all the values contribute to Tn: n 1 2 3 4 5 6 an : n x n! 1 4 18 96 600 4320 an+1 : (n + 1) x (n + 1)! 4 18 96 600 4320 35280 (n + 1)! 2 6 24 120 720 5040 (n + 2)! 6 24 120 720 5040 40320 n! 1 2 6 24 120 720 cn : (n + 2)! n! 5 22 114 696 4920 39600 T1 = c1 = 1 T2 = c1 + c2 = 5 + 22 = 27 T3 = c1 + c2 + c3 = 5 + 22 + 114 = 141 T4 = c1 + c2 + c3 + c4 = 5 + 22 + 114 + 696 = 837 T5 = c1 + c2 + c3 + c4 + c5 = 5 + 22 + 114 + 696 + 4920 = 5757 T6 = c1 + c2 + c3 + c4 + c5 + c6 = 5 + 22 + 114 + 696 + 4920 + 39600 = 45357 Tn 5 27 141 837 5757 45357 Looking at the column of (n + 1)!, (n + 2)! and Tn, when I add (n + 1)! to (n + 2)!, there is a constant difference of 3 between the sum and Tn. According to what I have found out, Tn can be express mathematically like this: Tn = (1 + 2)! 1! + (2 + 2)! 2! + (3 + 2)! 3! + (n + 2)! n! = (n + 1)! + (n + 2)! 3 Tn = c1 + c2 + c3 + c4 + c5 + + cn-1 + cn ? cn = (n + 2)! n! Tn = (1 + 2)! 1! + (2 + 2)! 2! + (3 + 2)! 3! + (4 + 2)! 4! + (5 + 2)! 5! + + (n 1 + 2)! (n 1)! + (n + 2)! n! = 3! 1! + 4! 2! + 5! 3! + 6! 4! + 7! 5! + + (n + 1)! (n 1)! + (n + 2)! n! At this step, I can see that many numbers cancel out each other except (-1!), (-2!), [(n + 1)!] and [(n + 2)!] as it goes on to the last term: = (n + 1)! + (n + 2)! 1! 2! ? Tn = (1 + 2)! 1! + (2 + 2)! 2! + (3 + 2)! 3! + (n + 2)! n! = (n + 1)! + (n + 2)! 3 In conclusion, throughout the investigation, I have used different methods to find out patterns of the sequences and successfully conjecture expressions for different sequences. Moreover, to prove the conjecture, I used not only by mathematical induciton, but also another method which I carried out for the last part. The 2 main conjectures I have made is: Sn = (n + 1)! 1 Tn = (n + 1)! + (n + 2)! 3 And both of the expressions are true for all positive integers n.

A Survey on Fingerprint Mathing Algorithms

A Survey on Fingerprint Mathing Algorithms In this networked world, users store their significant and less significant data over internet (cloud). Once data is ported to public Internet, security issues pop-up. To address the security issues, the present day technologies include traditional user-id and password mechanism and a onetime password (two-factor authentication). In addition to that, using the inexpensive scanners built into smartphones, fingerprint authentication is incorporated for improved security for data communication between the cloud user and the cloud provider. The age old image processing technique is revisited for processing the fingerprint of the user and matching against the stored images with the central cloud server during the initial registration process. In this paper, various fingerprint matching algorithms are studied and analyzed. Two important areas are addressed in fingerprint matching process: fingerprint verification fingerprint identification. The former compares two fingerprint and says they are similar or not; while the latter searches a database to identify the fingerprint image which is fed in by the user. Based on the survey on different matching algorithms, a novel method is proposed. Keywords: image processing, biometrics, fingerprint matching, cloud, security Introduction Automated fingerprint recognition systems have been deployed in a wide variety of application domains ranging from forensics to mobile phones. Designing algorithms for extracting salient features from fingerprints and matching them is still a challenging and important pattern recognition problem. This is due to the large intra-class variability and large inter-class similarity in fingerprint patterns. The factors responsible for intra-class variations are a) displacement or rotation between different acquisitions; b) partial overlap, especially in sensors of small area; c) non linear distortion, due to skin plasticity and differences in pressure against the sensor; d) pressure and skin condition, due to permanent or temporary factors (cuts, dirt, humidity, etc.); e) noise in the sensor (for example, residues from previous acquisitions); f) feature extraction errors. Fingerprint identification system may be either a verification system or an identification system depending on the context of the application. A verification system authenticates a person’s identity by comparing the captured fingerprint with her/his previously enrolled fingerprint reference template. An identification system recognizes an individual by searching the entire enrolment template database for a match. The fingerprint feature extraction and matching algorithms are usually quite similar for both fingerprint verification and identification problems. Fingerprint – Identification and Verification using Minutiae Based Matching Algorithms Fingerprints are commonly used to identify an individual. Research also suggests that fingerprints may provide information about future diseases an individual may be at risk for developing. Fingerprints are graphical flow-like ridges in palm of a human. Fingerprint is captured digitally using a fingerprint scanner. Fingerprints are commonly used to identify an individual. Research also suggests that fingerprints may provide information about future diseases an individual may be at risk for developing. Fingerprints are graphical flow-like ridges in palm of a human, that are unique amongst human beings. The hardware, fingerprint scanners are becoming low cost devices. The two most important ridge characteristics are ridge ending and ridge bifurcation. Automatic fingerprint identification systems (AFIS) have been widely used. An AFIS consists of two phases: offline and online. In the off-line phase, a fingerprint is acquired, enhanced using different algorithms, where features of the fingerprint are extracted and stored in a database as a template. In the on-line phase, a fingerprint is acquired, enhanced and features of the fingerprint are extracted, fed to a matching model and matched against template models in the database as depicted in the figure 1. Among all the biometric techniques, fingerprint-based identification is the most common used method which has been successfully used in numerous applications. Comparing to other biometric techniques, the advantages of fingerprint-based identification are as detailed below: The minutiae details of individual ridges and furrows are permanent and unchanging. The fingerprint is easily captured using low cost fingerprint scanner. Fingerprint is unique for every person. So it can be used to form multiple passwords to improve the security of the systems. Flow of Diagram representing the Fingerprint Identification The above figure clearly explains the simple methodology of fingerprint verification. In off-line process, the fingerprint of all users are captured and stored in a database. Before storing the raw or original image, the image is enhanced. The fingerprint image when captured for the first time may contain unwanted data ie noise. Because our hands being the most used part of our body may contain wetness, dry, oily or grease; and these images may be treated as noise while capturing the original fingerprint. And hence, to remove the noise, image enhancement techniques like adaptive filtering and adaptive thresholding. Original Fingerprint Image. The standard form factor for the image size is 0.5 to 1.25 inches square and 500 dots per inch. In the above original image, the process of adaptive filtering and thresholding are carried out. The redundancy of parallel ridges is a useful characteristic in image enhancement process. Though there may be discontinuities in a particular ridge, we can determine the flow by applying adaptive, matched filter. This filter is applied to every pixel in the image and the incorrect ridges are removed by applying matched filter. Thereby, the noise is removed and the enhanced image is shown in figure 3. Enhanced Fingerprint Image The enhanced image undergoes feature extraction process wherein: binarization and thinning take place. All fingerprint images do not share same contrast properties as the force applied while pressing may vary for each instance. Hence, the contrast variation is removed by this binarization process using local adaptive thresholding. Thinning is a feature extraction process where the width of the ridges is reduced down to a single pixel. The resultant feature extraction is shown below figure 4. Feature Extraction After Binarization and Thinning The process of minutiae extraction is done as the last step in feature extraction and then the final image is stored in database. Operating upon the thinned image, the minutiae are straightforward to detect and the endings are found at the termination points of thin lines. Bifurcations are found at the junctions of three lines. Feature attributes are determined for each valid minutia found. These consist of: ridge ending, the (x,y) location, and the direction of the ending bifurcation. Although minutia type is usually determined and stored, many fingerprint matching systems do not use this information because discrimination of one from the other is often difficult. The result of the feature extraction stage is what is called a minutia template, as shown in figure 5. This is a list of minutiae with accompanying attribute values. An approximate range on the number of minutiae found at this stage is from 10 to 100. If each minutia is stored with type (1 bit), location (9 bits each for x and y), and direction (8 bits), then each will require 27 bits say 4 bytes and the template will require up to 400 bytes. It is not uncommon to see template lengths of 1024 bytes. Minutiae Template Now, the online process starts. At the verification stage, the template from the claimant fingerprint is compared against that of the enrollee fingerprint. This is done usually by comparing neighborhoods of nearby minutiae for similarity. A single neighborhood may consist of three or more nearby minutiae. Each of these is located at a certain distance and relative orientation from each other. Furthermore, each minutia has its own attributes of type (if it is used) and minutia direction, which are also compared. If comparison indicates only small differences between the neighborhood in the enrollee fingerprint and that in the claimant fingerprint, then these neighborhoods are said to match. This is done exhaustively for all combinations of neighborhoods and if enough similarities are found, then the fingerprints are said to match. Template matching can be visualized as graph matching that is comparing the shapes of graphs joining fingerprint minutiae. A 1:1 matching cannot be carried out and we use a threshold value – termed as match score, usually a number ranging between 0 and 1. Higher the value, higher is the match. Figure 6: Few- Matching in online process Minutiae are extracted from the two fingerprints and stored as sets of points in the two dimensional plane. Minutia-based matching consists of finding the alignment between the template and the input minutiae feature sets, that results in the maximum number of minutiae pairs. 1) Weiguo Sheng et.al In their paper, the authors proposed a memetic fingerprint matching algorithm that aimed to identify optimal global matching between two sets of minutiae. The minutiae local feature representation called the minutiae descriptor that had information about the orientation field sampled in a circular pattern around the minutiae was used by them in the first stage. In the second stage, a genetic algorithm(GA) with a local improvement operator was used to effectively design an efficient algorithm for the minutiae point pattern matching problem. The local improvement operator utilized the nearest neighbor relationship to assign a binary correspondence at each step. Matching function based on the product rule was used for fitness computation. Experimental results over four fingerprint databases confirmed that the memetic fingerprint matching algorithm(MFMA) was reliable. 2) Kai Cao et al A penalized quadratic model to deal with the non-linear distortion in fingerprint matching was presented by the above authors. A fingerprint was represented using minutiae and points sampled at a constant interval on each valid ridge. Similarity between minutiae was estimated by the minutia orientation descriptor based on its neighboring ridge sampling points. Greedy matching algorithm was adopted to establish initial correspondences between minutiae pairs. The proposed algorithm used these correspondences to select landmarks or points to calculate the quadratic model parameters. The input fingerprint is warped according to the quadratic model, and compared with the template to obtain the final similarity score. The algorithm was evaluated on a fingerprint database consisting of 800 fingerprint images. 3) Peng Shi et.al In their paper, the authors proposed a novel fingerprint matching algorithm based on minutiae sets combined with the global statistical features. The two global statistical features of fingerprint image used in their algorithm were mean ridge width and the normalized quality estimation of the whole image. The fingerprint image was enhanced based on the orientation field map. The mean ridge width and the quality estimation of the whole image were got during the enhancement process. Minutiae were extracted on the thinned ridge map to form the minutiae set of the input fingerprint. The algorithm used to estimate the mean ridge width of fingerprint, was based on the block-level on non-overlap windows in fingerprint image. Four databases were used to compute the matching performance of the algorithm. 4) Sharat Chikkerur et.al The local neighborhood of each minutiae was defined by a representation called K-plet that is invariant under translation and rotation. The local structural relationship of the K-plet was encoded in the form of a graph wherein each minutiae was represented by a vertex and each neighboring minutiae by a directed graph. Dynamic programming algorithm was used to match the local neighborhood. A Coupled Breadth First Search algorithm was proposed to consolidate all the local matches between the two fingerprints. The performance of the matching algorithm was evaluated on a database consisting of 800 images. 5) Jin Qi and Yang Sheng Wang They proposed a minutiae-based fingerprint matching method. They defined a novel minutiae feature vector that integrated the minutiae details of the fingerprint with the orientation field information that was invariant to rotation and translation. It captured information on ridge-flow pattern. A triangular match method that was robust to non-linear deformation was used. The orientation field and minutiae were combined to determine the matching score. They evaluated the performance of their algorithm on a public domain collection of 800 fingerprint images. 6) Atanu Chatterjee et.al Another method for fingerprint identification and verification by minutiae feature extraction was proposed by the above authors. Minutiae were extracted from the thinned ridges from the fingerprint images and these feature matrices were applied as input data set to the Artificial Neural Network. Post processing was done to remove false minutia. Back propagation algorithm was used to train the network. Extracted features of the input fingerprint were verified with stored trained weights and threshold values. Experiments were conducted on 160 fingerprint images and the proposed system exhibited an accuracy of 95%. 7) Tsai Yang Jea et.al A flow network-based fingerprint matching technique for partial fingerprints was introduced by. For each minutiae along with its two nearest neighbors, a feature vector was generated which was used for the matching process. Minimum cost flow (MCF) problem algorithm was used to find the one-to-one correspondence between the feature vectors and the list of possibly matched features was obtained. A two hidden layer fully connected Neural Network was proposed to calculate the similarity score. Their experiments on two fingerprint databases showed that using neural networks for generating similarity scores improved accuracy. 8) Marius Tico et.al They have proposed a method of fingerprint matching based on a novel representation for the minutiae. The proposed minutiae representation incorporated ridge orientation information in a circular region, describing the appearance of the fingerprint pattern around the minutiae. Average Fingerprint Ridge period was evaluated to select the sampling points around the minutiae. Matching algorithm was based on point pattern matching. To recover the geometric transformation between the two fingerprint impressions, a registration stage was included. The Greedy algorithm was used to construct a set of corresponding minutiae. Experiments were conducted on two public domain collections of fingerprint images and were found to achieve good performance. 9) Asker M.Bazen et. al A minutiae matching method using a local and global matching stage was presented by Asker M. Bazen et. Al. Their elastic matching algorithm estimated the non-linear transformation model in two stages. The local matching algorithm compared each minutia neighborhood in the test fingerprint to each minutia neighborhood in the template fingerprints. Least square algorithm was used to align the two structures to obtain a list of corresponding minutia pairs. Global transformation was done to optimally register the two fingerprints that represented the elastic deformations by a thin-plate spline (TPS) model. The TPS model describes the transformed coordinates independently as a function of the original coordinates. Local and global alignments were used to determine the matching score. Conclusion This paper, we presented Fingerprint identification and verification based on minutiae based matching. The original fingerprint captures is pre-processed and the pattern is stored in the database for verification and identification. The pre-processing of the original fingerprint involves image binarization, ridge thinning, and noise removal. Fingerprint Recognition using Minutiae Score Matching method is used for matching the minutiae points. Usually a technique called minutiae matching is used to be able to handle automatic fingerprint recognition with a computer system. In this literature review, nine papers are explored and an insight is obtained regarding different methods.

Multistep reserach - Research Paper Example At the same time, burning it pollutes the environment as well. The objective of this paper is to discuss various forms of transport and their impacts to the society. Transport is a primary contributor to the process of industrialization. It facilitates the movement of raw materials to manufacturers, and processed products to potential buyers. It also assists in the creation of employment opportunities, for instance, it employs drivers and pilots (Organisation for Economic Co-operation and Development 90). Thus, enhances standards of living. Transport networks and mechanisms assist greatly during emergencies and natural calamities. They provide a means through which people and property can be moved from volatile to safer areas. Air transport involves the use of planes, choppers, and air balloons. It is the most efficient means of transport when it comes to business connectivity and efficiency. It is also reliable for leisure since it offers an aerial view for diverse views and is quite fast. Reliable air transportation facilitates international tourism and faster transportation of goods, particularly perishable goods, more than any other means. Thus, it is an important instrument for economic growth. It is a fundamental instrument of globalization. This is because, it has a high capacity for enhancing integration of political, economic, social and cultural activities at an international level. It is the most expensive mode of transport, and therefore, often reserved for affluent travelers (Daley 1). In the occurrence of natural calamities air transport is usually the most convenient mode of movement of goods and people. Air transport is often affected by adverse weather conditions and is quite uneconomical for short distance movement. In terms of security, air transport accidents are usually the harshest as it normally leads to massive damage of goods and loss of life.

Do police reduce crime(Know how to use stata) Research Paper

Do police reduce crime(Know how to use stata) - Research Paper Example After a terrorist attack that took place in July 1994, Argentina, the main Jewish center in Buenos Aires, it led to all Jewish institutions receiving police protection. Hence, this hideous event initiated a police force geographical allocation that can be presumed exogenous in a crime regression. Using data on the car thefts after and before the attack, the study found out a significant effect of police on crime. The impact was observed to be local, with no impact outside the small area where the police were deployed. Introduction In the study a different approach has been presented to estimate the police on crime causal effect. Terrorists exploded a bomb on July 18, 1994 that brought down the Asociacion Mutual Israelita Argentina (A.M.I.A.), which is the key Jewish center in Argentina. This saw 85 persons dyeing and at least 300 were injured in the attack. The federal government had to assign police one week later in order to protect every Muslim and Jewish building in the country. These were done because the institutions’ geographical distribution was presumed to be ‘exogenous in a crime regression,’ this hideous event is composed of a natural experiment where the simultaneous determination of police presence and crime might be broken. The motor vehicle thefts number per block information was collected in 3 neighborhoods in Buenos Aires after and before the terrorist attack. The information includes a period of 9 month starting April 1 to December 31, 1994. Information on each Jewish institution location in these neighborhoods was also collected. There was then an estimation of the police presence effect on car theft. The estimates indicated that blocks which received police protection had substantially fewer car thefts as compared to the rest of the neighborhoods. There was no evidence that the presence of police in a certain block reduced car theft one or two blocks that was away from the buildings which were protected. There has been a major interest to identify the mechanisms where presence of police reduces crime. Is it that the presence of police results to criminal activity to be less attractive or is it that police men arrested criminals and few of them were left around to com- on car thefts? The total number of car thefts per block was used as the dependent Variable; this gave a panel with nine observations for every given block. This data on blocks without and with protected institutions enabled us to define a control and treatment group. Month fixed effects were included that controlled any aggregate shocks in the crime evolution. The main procedure utilized in this study was regression analysis. It was utilized to explain the total variation of the dependent variable, Car theft. The dependent variable was accompanied by 9 variables, which were tested against the dependent variable to determine how much of the total variation is explained. The analyses also discussed the comparison of the different regress ion models, and determine which model is the most effective. In regards to the regression analysis results, it is clearly evident that model 2 is the strongest. The independent variables including street, dummy Jews institution one block away, block distance to closest institution and dummy gas station were omitted and not included in the second model because there P value was greater than 0.05 implying the data collected was either not valid or there was no enough evidence to make

Muted Women in Virginia Woolf’s A Room of One’s Own and Elizabeth Barre

Muted Women in Virginia Woolf’s A Room of One’s Own and Elizabeth Barrett Browning’s Aurora Leigh In the predominantly male worlds of Virginia Woolf’s A Room of One’s Own and Elizabeth Barrett Browning’s â€Å"Aurora Leigh (Book I)†, the women’s voices are muted. Female characters are confined to the domestic spheres of their homes, and they are excluded from the elite literary world. They are expected to function as foils to the male figures in their lives. These women are â€Å"trained† to remain silent and passive not only by the males around them, but also by their parents, their relatives, and their peers. Willingly or grudgingly, the women in Woolf and Browning’s works are regulated to the domestic circle, discouraged from the literary world, and are expected to act as foils to their male counterparts. Without the means of securing financial independence, women are confined to the world of domestic duties. In Woolf’s A Room of One’s Own, Mary Seton’s â€Å"homely† mother is neither a businesswoman nor a magnate on the Stock Exchange. She cannot afford to provide formal education for her daughters or for herself. Without money, the women must toil day and night at home, with no time for learned conversations about â€Å"archaeology, botany, anthropology, physics, the nature of the atom, mathematics, astronomy, relativity, geography† – the subjects of the men’s conversations (26). As Woolf notes, if Mary’s mother had gone into business, there would have been no Mary. Children are financial burdens and they make heavy demands on a mother’s time. It is impossible that a mother could feed and play with their children while making money, because women are expected to raise large families; they are the ones who ca rry o... ...n. And muted the women are, in A Room of One’s Own and â€Å"Aurora Leigh†. They cannot vocalize their opinions, wants, and needs when they are confined to their homes and discouraged from joining the predominantly male literary circles. Moreover, females are expected to act as foils to the males so that the patriarchal societies may flourish. Coleridge once said that a great mind is androgynous (Woolf, 106). When the men and women can cooperate and unite their minds and bodies, Shakespeare’s gifted sister will be able to re-emerge, freeing the muted voices of these oppressed women.

Anna Avalon Character Sketch Essay

Anna Avalon, the adventurous and admirable main character of â€Å"The Leap’ written by Louise Erdich has many traits that prove her to be a very admirable woman. Her daughter is very grateful to have her as a mother. Throughout this short story, it is quite easy to see that Anna Avalon is talented, careful and brave. Considered to be â€Å"The surviving half of a blindfold trapeze act† (Pg. 190) Anna Avalon is very talented. She had previously been a performer. â€Å"Anna of the Flying Avalon’s† She had been involved in many performances and was definitely a crowd favourite, Anna had performed many â€Å"Double somersaults and heart-stopping catches† (Pg. 90) However, one day there had been a tragic accident. While seven months pregnant, lightning struck a pole resulting in three deaths. â€Å" Lightning struck the main pole and sizzles down the guy wires, filling the air with a blue radiance† (Pg. 192) Anna was the only one who survived this tragic accident, this showing her talent. Along with talented, Anna Avalon is very careful. She is an elderly lady living in New Hampshire, with sightless eyes. Although blind, â€Å"she has never upset an object or as much as brushed a magazine onto the floor. She has never lost her balance or bumped into a closet door left carelessly open. The â€Å"catlike precision of her movements’ (Pg. 190) is probably due to her early training. When caught in a house fire, Anna was willing to risk her own life in order to save her daughter. This shows that she’s a brave and courageous woman and would do anything for her child. Several years ago, Anna Avalon’s house caught on fire, when her daughter was just seven years old. The staircase to her upstairs room had been cut off by flames so everyone was outside thinking there was no rescue. â€Å"Outside, my mother stood below my dark window and saw clearly that there was no rescue. (Pg. 195) However, Anna Avalon did everything in her power to assure her daughter would be safe. â€Å"Standing there, beside Father, who was preparing to rush back around to the front of the house, my mother asked him to unzip her dress. When he wouldn’t be bothered, she made him understand. He couldn’t make his hands work, so she finally tore it off and stood there in her pearls and stockings. She directed one of the men to lean the broken half of the extension ladder up against the trunk of the tree. † (Pg. 195) Anna had well thought out a way to save her seven year old. She leaped through the icy-air and â€Å"was hanging by the backs of her heels from the new gutter†. (Pg. 195) She then tapped on the window to let her daughter know she came to rescue her. Although she was only in her underclothing, she had bigger things to worry about, such as saving her daughter. She successfully saved her daughter, showing her true heroism and bravery. Throughout â€Å"The leap’ it’s clear that Anna is very admirable. She has done many things in her life to help others and we see that she is a wonderful person. From her actions, Anna Avalon is talented, careful and brave.

Coffee Consumption The Health Benefits - 1831 Words

Coffee Consumption: The Health Benefits By: Kate Spinosa â€Å"Americans run on Dunkin†, this is a phrase that almost everyone knows or has heard in their lifetime. Over 500 billion cups of coffee are consumed annually worldwide [1]. There are on average 70 countries that grow the coffee plant for coffee production, and coffee trade is exceeding 10 billion dollars worldwide [1]. While water is the most consumed drink globally, coffee is the actually the next most consumed beverage [1].

I wanted to know the specific components of coffee that decreased risks of developing cancer and how effective this was. I found that as of 2010 there were ne arly 400 published studies of epidemiologic research on the topic of coffee and cancer [4]. This shows that there is a large amount of interest in this topic and much research dedicated to discovering findings. Coffee consumption has claims to most typically help lessen the risk of developing liver, renal, skin, ovarian, colorectal, esophagus, and pharyngeal cancer [1]. The rich phytochemisty/antioxidant component of coffee is what lowers the risk of developing cancer. One study taken showed results of a 36% decrease risk for nonmelanoma skin cancer from six or more cups of caffeinated coffee daily [1]. Malignant hepatoma (HCC) is a common form of liver cancer which can be prevented more so with coffee consumption [1]. Liver cancer is the 5th most common cancer in males and 8th in females [5]. Three separate studies showed the results of a high consumption of coffee (6+ cups) compared to a almost never consumption (1 cup) which gave a 50%, 55% and 43% reduction rate for liver cancer in subjects [5]. Between 1990 and 2003 among 147,227 subjects, 3 cohorts, and 15 case-control studies, and 11 countries, the results showed a 24% lower risk of colon cancer per cup consumed fromShow MoreRelatedHealth Benefits And Side Effects On The Consumption Of Coffee2973 Words   |  12 PagesIntroduction The consumption of coffee is an essential staple to start an early morning in the United States and worldwide (Freedman et al. 2012).
