Abstract— Biometric time and attendance system is one of the most successful applications of biometric technology. One of the main advantage of a biometric time and attendance system is it avoids "buddy-punching". Buddy punching was a major loophole which will be exploiting in the traditional time attendance systems. Fingerprint recognition is an established field today, but still identifying individual from a set of enrolled fingerprints is a time taking process. Most fingerprint-based biometric systems store the minutiae template of a user in the database. It has been traditionally assumed that the minutiae template of a user does not reveal any information about the original fingerprint. This belief has now been shown to be false; several algorithms have been proposed that can reconstruct fingerprint images from minutiae templates. In this paper, a novel fingerprint reconstruction algorithm is proposed to reconstruct the phase image, which is then converted into the grayscale image. The proposed reconstruction algorithm reconstructs the phase image from minutiae. The proposed reconstruction algorithm is used to automate the whole process of taking attendance, manually which is a laborious and troublesome work and waste a lot of time, with its managing and maintaining the records for a period of time is also a burdensome task. The proposed reconstruction algorithm has been evaluated with respect to the...

Journals and Scientific Docs

...Journals and Scientific Documents The purpose of journals and professional papers is to inform the public on a specific subject matter. These writings relate directly to a broad spectrum dependent on the edition or publication specifics. Of professional papers, several types can provide a scope of information and credibility toward a purveyance of technical or detailed information. The structure is usually even flowing and organized with particular information segments set out about the constituency of the writing. These papers, intended for publication in special interest journals, enhance the writers research, writing, and documentation capabilities as some of the information, not being his/her own will need to be accredited as if it is not, than plagiarism will be extrapolated. Journals, usually published by or for a particular subject matter or client, are detailed and accurate. There may be a UCLA journal, National Geographic Journal, or even a mechanic’s journal. The particulars of this, geared toward a particular audience and each entry, will usually comprise two titles sharing a general viewpoint for the nonprofessional and an entry specific title for the professional. The purpose of journals is to inform a group or individual of the credible elements related to a curriculum or scientific, professional, or academic scope. The writings or information in a journal may be composed of professional papers but the opposite is not the same. ...

Difference Between Journals and Diaries: -

...Difference between journals and diaries:- The difference between a diary and a journal is that a diary is where you can write down what happened during the day and keep a record of stuff. A journal is to write your own personal feelings in, and things that happened, and how they happened. A diary is a report of what happened during the day—where you ate, who you met, the details that what was happened in the office, and who took whose side. It is a like a newspaper about you. A journal is completely different. A journal is about examining your life. It’s a GPS system for your spirit. Journals lead to insight, growth, and sometimes, achieving a goal. You can keep a journal in anything that feels comfortable and that’s portable–a spiral notebook, a bind book you have put together with lokta paper, index cards held together with a rubber band. You can use a computer; keep a blog, although that doesn’t work as well for me. But things on the internet are simply not private, password protected or not. To keep a journal on paper, pick a time of day to write. Keep it regularly. It makes it easier. Try that you didn’t stuck to an exercise program because then it can nailed it into schedule at a certain time. Writing works the same way. First thing in the morning, last thing at night, while eating lunch at your desk. Write with a good pen that feels good and whose color you like. In the beginning, you may have to set a time limit. Three minutes is good. Just write whatever......

Teacher Assessments

...As a teacher it is your responsibility to not only present new material to the student but to teach them and to verify and monitor what information they are actually obtaining and processing. There are many forms of assessments that teachers can use to evaluate students understanding of lesson material. I will suggest a few methods that I will use in my secondary education mathematics classroom. The first strategy of monitoring I will discuss will be quizzes. There are multiple advantages for this form of testing. First, is that it easily produces recorded data. I can quickly grade multiple choice questions and record the students’ grade. Being able to record this grade will allow me to present scores to the parents when I am asked for a student’s progress. Another advantage to a quiz is the ability to assess both the entire class and each individual’s understanding on a topic. I will be able to look at the overall measurement and decide whether there is a need to review the topic or lesson, or if the class is ready to advance in the given studies. Also, by presenting multiple quizzes through the term the students and I can create a set format, which can help ease classroom anxiety. Another form of monitoring students’ progression through a lesson is homework. Homework can be one of the most effective methods for tracking mathematical progress. Assigning, collecting and grading homework can be a very timely way to gather information on how each student is progressing......

...Since the very beginning of my days as a student, I have despised literature. English has always been a subject that I dreaded. I do not loathe literature solely for my lack of writing skills, because I do enjoy reading, rather it’s the fact that I tend to lose my train of thought while writing an essay or while brainstorming an idea I want to address. I struggle with organizing my thoughts and making concise relationsHIPS[?][CONNECTIONS?] between literary texts and the assignments given by my teachers.

Family Dynamics

...The Dynamics of Writing and Family “Most successful men have not achieved their distinction by having some new talent or opportunity presented to them. They have developed the opportunity that was at hand." -- Bruce Fairchild Barton, advertising executive and congressman Uncle would say, "There are certain inalienable truths you must accept." So when I raged about Atheists being disqualified for holding office in Arkansas or how it's illegal to carry a bible in Singapore, he'd say, "Write it down. Let it out." I've filled four journals. On an idle Thursday, when my mind was free of frustration, I read the crumpled, yellowed pages of my black leather journal and saw a natural progression from black to color. I had precisely captured all my experiences, but in an entirely aesthetic way. From then on, every time I opened my journal, I found myself in an unfamiliar environment writing to capture a mood or scene with creative language. It was my therapeutic getaway from reality. In the summertime, every Sunday, after taking a rattling cold bus, two smoky, humid subway trains, and picking up the best peanuts on 114th street, I would arrive at Riverside Park, New York. I wrote at least one piece every time I was there and shared my work with the same old man who perused the New York Times and the same skinny college student who sunbathed in her bikini. After noting any criticism they gave, I would return home, edit and embellish each piece. ...

Business Research Methods Res/351

...Medical Journals and the Failure of Trust” the issue of pharmaceutical businesses and their research, and how it is presented is outlined. The article covers one of the largest controversies with business research conducted by GlaxoSmithKline (GSK) and how the results were skewed and then reported by many medical journals as fact, even though the research did not support what was reported. The study was GSK 329, which showed a particular drug to be effective in adolescents with depression, even though the testing showed otherwise. (Jureidini & McHenry, 2011) The biggest unethical behavior that was demonstrated by GSK, and medical journals was the skewing of results of a study. Medical journals published articles that misrepresented the findings of GSK’s research. Internal reports by the company showed that their trials of the drug had failed to benefit adolescents with depression, and positively showed that there were negative results. (Jureidini & McHenry, 2011) The internal report states that “it would be commercially unacceptable to include a statement that efficacy had not been demonstrated, as this would undermine the profile of paroxetine,” and that “to effectively manage the dissemination of data in order to minimize any potential negative commercial impact.” (Jureidini &McHenry, 2011) This indicates that they skewed the results of the study so that only selective data would be published. The authors also place blame on the medical journals that......

...that will take us briefly through the research process. Let’s pretend that we’re all taking an ENGL 1001 class this semester and that we are required to write a paper on a current event, issue, or controversy. As part of our research for the paper, we are required to complete an annotated bibliography. An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited. Our instructor has informed us that we need to use 6 total sources for our annotated bibliography: * 3 must be scholarly journal articles * 3 can be a mix of popular articles, reference sources, internet sources, images, statistical sources, etc. * The information must be current, and must not have publication dates or cover dates before the year 2000 * You must cite articles in the APA style. We know that the first thing we should do as researchers is look up the topic in a reference source to gain a bit of knowledge about the topic, become familiar with the vocabulary used to write about and discuss the topic, and to start noting the cited references included in entries that will lead us to other sources of information. Our first stop is our Reference Sources. Search for Traumatic Brain Injury in Wikipedia. Ideally, in a true research......

I did look over the project management reference guide. I better understanding of what’s expected for the capstone. The reason I didn’t get much done was because I was getting stuff ready for Christmas. Every time I thought I was finished, I’d get another call saying I need more help. I thought I’d only be busy on Thursday, but that didn’t work out. I got a call on Friday and Saturday as well. I should’ve got started yesterday but that wasn’t happening either, football Sunday. So I guess I’ll have to make it up this weekend. This project is going to be difficult. It entails a lot of work. We have to come up with a project name, which we haven’t done yet. We have to have a risk management plan, a change management plan, a quality management plan, and a project charter. All of which is going to take careful planning and a lot of research. Hopefully we will be able to come to the same conclusions on how this should be laid out, financed and implemented.

This choice has been strongly influenced by the Pediatric Therapists that I have been involved with when dealing with the special needs of my youngest child and also my own experience as a Certified Nursing Assistant. Observation and Assessment; by observing a child in a neutral or if you will there natural environments and simply documenting there active daily living skills or what is more commonly referred to in the Health Care Profession A.D.L.’s you can gain understanding of where there strengths and weaknesses are. When you observe a child within their peer group you can quickly gain an understanding if there developmental skills are lesser than or equal to others of their peer group. Take for example my son he is 41 months old and appears at first glance to be appropriately physically developed with no disabilities. Placing him within his peer group and simply observing his behavior and interactions with his peers will immediately entice you to observe him in more detail. When walking away you will notice that his knees turn inward and he appear to be dragging his right leg and walking on the inner portion of his......
