Blood Brothers Superstition Essays

Blood Brothers Superstition Essays Blood Brothers Superstition Essay Blood Brothers Superstition Essay Essay Topic: Play Over the past term, me and my fellow classmates have studied the play Blood Brothers by Willy Russell. The hit West-End show follows the story of two twins, separated at birth and brought up in two very different social backgrounds; one growing up in a rich family, while the other remains with his real mother in a poor family, living in the slums of Liverpool. The play explores many themes, ranging from the problems of society, to the possibility of superstition playing a massive part on life. After we watched Blood Brothers, we acted out certain scenes from the script and attempted to use various techniques to portray the story in many different ways. Blood Brothers tells the tale of Mickey and Eddie, two twins separated at birth due to a number of reasons. The first act introduces the story, and examines the events leading up to the birth. It also witnesses their first meetings as children. This part of the play is very comedic, however the frequent use of the narrator (who plays a paramount role throughout the play) quickly shifts what appears to be a funny scene into a dark and eerie one. The second act sees the reunion of the brothers, now hit with puberty, and an increasing sense of competition. Although initially positive, the story takes a turn for the worse when Mickey is badly affected by the poor economy of the 80s, and turns to crime as a source of income. He is then arrested, and falls into a deep sense of depression, despite being recently married to his teenage love, Linda (whom Eddie also shares a love of). The play comes to a climactic ending, where both brothers are killed following Mickeys mental breakdown. The play discusses (in a slightly left-wing fashion) the problems of a class system in society, and how this can tear families apart, and ruin lives. It also investigates whether superstition plays a role on life, with the narrator constantly supporting this idea. Mickey, is one of the brothers who still lives with his real mother, while Eddie grows up in a more upper-class background. The pair are very friendly to each other to start with, and their friendship grows, but then collapses towards the end. Mrs Johnstone is the real mother who was left by her husband a few years before. Mrs Lyons is the woman who Eddie is brought up to know as Mother, who like Mickey suffers a mental breakdown. These two, unlike their sons despise each other a little way into the plot. When we read the script, the very first scene we performed was opening of the play in Act One. This scene studies the events leading up to the birth of the twins, and how Mrs Johnstone could be convinced to give up one of her sons. The main reason for her seemingly cruel decision was to still be able to look after her family financially. She claims that had she only one child, she could provide enough food for everyone, however with any more it was impossible. To make this scene interesting, we used a range of different techniques. The first and most obvious was role-play, a drama medium (various ways to communicate dramatically to the audience). We did this by attempting Liverpudlean accents, doing different gestures, and moving in unique ways that we believed the characters would in real life. In this scene, I played the milkman and gynaecologist. The milkman had a very stereotypical Liverpudlean voice, and a slightly lazy posture to illustrate his boredom of delivering milk day in and day out. The gynaecologist however, was quite the opposite. He was well-spoken, and took a rather positive view on life. His movements were quick and small. The milkman, like Mrs Johnstone was fed up with life, and was feeling the hardships of life more than others. The doctor was happier, partly because of his social status. The small choice of changing some attributes contributed to showing how much class played a part on life. Another technique we used was props. We had to bring in an object that would help portray the character. I brought in an empty glass bottle that helped show the characters profession. This scene was important to the play as it laid out the path for the story to continue. One of the other groups performed the scene where Eddie becomes very angry with his mother for not allowing him to play with Mickey. They used still image to mark a specific moment. This made the scene memorable, and that point stand out. In the second act, we performed the scene where Mickey argues with Linda over why he needs his pills. The scene is very depressing, and shows how hard Mickeys life is. I played Mickey, and once again used role-play. His movements were a lot slower than in the first act, and he was much quieter. However a technique that I felt made the scene more interesting was mime. As another part of the scene was going on, I acted out silently in the background Mickey at work, trying to stop the urge to take his anti-depressants. We utilised staging, an explorative strategy to make the scene more interesting for the viewer, while still understandable. As the scene went on, we also dimmed the lights to show Mickeys mental state getting more and more disturbed and unpredictable, this is an example of an element of drama we used. This scene was one of the last parts in the play where Mickey is sane, and shows what may have led him to go mad, and kill his former best friend. One group did the final scene, where both die. This scene is ultimately tragic, but also shows the consequences certain actions can have in the future. When Mickey shoots Eddie, they used slow motion (an explorative strategy) to show the importance of that scene. Overall, the work we have done so far has greatly improved my understanding of how to perform a scripted play to the audience by also using interesting techniques to portray a certain message. The work of other groups worked impeccably well at portraying the story behind the play, as did the work of ours. The range of techniques used created memorable and believable scenes that kept the audience captivated, and wanting more. The work this term has contributed greatly to my understanding of drama, and how to appreciate as well as enjoy other pieces of work that utilise these techniques.

8 Convenient Life Hacks for the Workplace

8 Convenient Life Hacks for the Workplace How do those people at work who always seem to have the right thing to say or do in any situation do it? How do people seem so confident and polished, when you always feel like you’re falling apart at the seams? Their tricks might be simpler than you think. It’s often the littlest things that make the biggest impact. Here are some convenient life hacks, pulled from real people who’ve used them in actual offices, to help you navigate your work life and come out on top.1. Dropbox your resumeEver been caught with your pants down and not had a copy of your resume when you really needed one? If you’re on the go, you can rest assured that you can email or print your resume directly from your phone if you use a service/app like Dropbox.2. Always type in the address lastYou’re writing an important professional email. You’re nervously wording everything perfectly. Make sure you don’t accidentally hit send before you’ve had a chance to lo ok it over. Make the address part the very last thing you type in. That way you always know you’re sending out a perfect, proofread product. No accidents! You can also set up (in Gmail based clients, anyway) a 5-10 second send delay, which gives you the chance to â€Å"undo† when you’ve sent too soon.3. Be the whiteboard heroSome numpty wrote on the office whiteboard in permanent marker? Rather than stare at whatever they wrote for the rest of your career, go over each mark with a normal whiteboard marker. Something magic happens between the two ink types that will make it possible to erase both together. For bonus points, charge admission to your magic trick.4. Take a chill pillIf you’re starting to feel overwhelmed and exhausted, even before you get to work, try building 2-5 minutes to yourself into your morning routine. Just sit with a cup of water, juice, or coffee and do nothing. Don’t even strategize about your day. Just be. You’ll fee l more rested and invigorated when you actually get back to your routine.5. Pay it forward–for yourselfWe’ve all had it happen: finish a job interview, walk outside, and realize immediately all the brilliant things you should have said. Write them down! Immediately and thoroughly. Then keep them for your next interview. 99.9% of it will be reusable, and very valuable. If you don’t get this job, you’ll have a great boost for the next.6. Hold your tongueIf we screw up, or we’re five minutes late, or we don’t have the document ready, it’s a knee-jerk reaction to preemptively apologize and offer up an explanation (read: excuse). Next time, hold on to it unless you’re asked for one. They might not have even noticed you were unprepared and the excuse will only serve to highlight what you did or didn’t do. Plus, nobody wants a reputation for making tons of excuses.7. Do the dirty deedOne way to distinguish yourself at work- and make yourself a hero- is to figure out the particular task or set of tasks that everyone else seems to avoid or hates to do, and do that. Well. Your niche in the office will be secure- even indispensable. And you’ll be the most popular employee around.8. Treat others how you would treat your bossSeriously. It is a little bit about popularity. Treat all of your coworkers, even your subordinates, as though they were the ones deciding about your raises and promotions and vacation requests. You never know who will make the difference in your career as it develops.â€Å"flair:’Careers Work

Impact of Technology on Education Essay Example | Topics and Well Written Essays - 2000 words

Impact of Technology on Education - Essay Example The No Child Left Behind Act (NCLB) in US lays an added emphasis1 on the use of technology for the betterment of the sector. Information Technology is the all important offspring of Technology having its footprints on the way education is imparted or educational material is prepared or education is accepted by the intended audience. Taking care of this fact, the Campus Computing Project (CCP) happens to be one of the largest continuing study programme about the role of IT in American higher education. As internet is gradually maturing and presenting a paradigm shift in its very ideation, the infrastructure has acquired a business character, a transcontinental personality and a vending framework of wide-ranging, business, educational, scientific and personal data. Now the use of internet covers real-time computer conferencing, audio broadcasting, video broadcasting, real time telephony and of course real-time business. Education too takes a leaf out of such applications and has been able to make good use of internet and related technologies. There is increasing participation of private and public sector together with government in making technology available to different aspects of educational needs. Apple Inc. a leading company using technology and computing for its business objectives, for example has partnered in many education related schemes like; Apple Classrooms of Tomorrow (ACOT), North Central Regional Education Laboratory (NCREL), International Data Corporation (IDC) etc . which helped not only in encouraging the use of technology in education, but also made fullest use of technology in promoting the cause of education. In his famous taxonomy, Bloom (1964) identified the domains within which learning takes place. He labelled them as cognitive, affective and psychomotor. Traditionally, the concentration has been on the cognitive domain with comprehension, facts and figures acquiring the centre stage. But with technology making its impact, information society made it almost compulsory for the education providers to bring into effect, adequate amendments in their approach so that the learning process becomes far more interactive and effective. In this new approach role of student as well as the means of education became more important. In fact this theory too has been in practice for quite a while now, as is evident from what Rogers (1961) said about the learning process. Rogers (1961) stated that the only learning that significantly influences human behavior happens to be self-discovered. The IT era has helped in making the learning process more interactive, and more relevant to the fast pace developm ent of the day. Education for sustainable development therefore focuses more on how people live, work and make decisions. The learning process in general involves; Learning values and cultures: Such an education is imparted by the parents and the society in general. How the parents behave, what are the means of communication used by the parents, how effectively the parents are able to manage their time and efforts towards the children, and what kind of social upbringing is the child subjected to, are some of the major contributors towards the value education. The ethics and cultures too are picked by the students from his/ her

The Bribery Scandal at Siemens AG Case Study Example | Topics and Well Written Essays - 1500 words

The Bribery Scandal at Siemens AG - Case Study Example In relation to the issues, some people analyzed different things that they could use as ways of justification of the events of the scandals and assumed that it was not a serious issue. For instance, Siemens AG officials did not accept that they had involved themselves in a case of bribery by saying that the money went to the payment of an external consultant. Otherwise, the court determined the case that the money coincided with procurement of some equipment from various international markets during the period. One of the most notable cases in the contract scandals involved â‚ ¬6 million, which some Siemens AG management had paid to some foreign officials involved in a natural gas turbine contract, which Siemens AG wanted to win. Siemens AG had involved itself in several other scandals in Germany and in other countries between 2005 and 2006, and some other cases were under investigations and not yet clarified. In defense, the convicted employees argued that the action was not a vi olation of any law because it never was for a personal gain, and said that it was a plan to secure a productive deal the company needed, and the money was part of the bid. The defense the Siemens employees raised was a misinterpretation of the law because they based their arguments on the issue that, it is the custom of multinational companies, to establish their businesses on bribery and corruption, to win international contracts. This was a deviation from the ethical laws which requires companies to exercise what is right in coming up with business deals that are related to the work they are doing. According to business ethics for multinational companies, an action is moral if doing it does not contravene the culture or the wellbeing of the host country. Although there are differences in culture, in different places in the world, a wrong act remains so regardless of the place of origin of the doer and the people who do it and the perceived benefits to the trading company (Boatrigh t 335). In some cases, differences in culture have influenced the conduct of the people in the business relations because the individuals in the context depend on the perspective of the residents of country in which they trade. Many companies practice double standards which make them neglect some ethical standards they bear from their home countries and in conforming to the standards of the foreign countries, do illegal activities (Boatright 335). This could be the reason why Siemens AG involved itself in different scandals in various countries in order to secure some opportunities in the market, and ensure their competitiveness. Question 2 In failing to extend the term of service of Klaus Kleinfeld, who was the Chief Executive officer (CEO) of Siemens AG, the supervisory board did not do the right thing. The board generalized the issues of the scandals without a clear focus to the criminals in the management in an attempt to clean up the name of the company in the world market. Des pite the fact that the supervisory board of Siemens AG did not get anything to  implicate  directly on  Kleinfeld in any of the scandals; he was an active person in establishing the company as a profitable business (Krishna and Purkayastha 11). The way of thinking of the supervisory board members to clean up the top management without considering the personal contribution of those individuals was a bad generalization. This is because the integrity of the

Image Based Steganography Using Lsb Insertion Technique Computer Science Essay

Image Based Steganography Using Lsb Insertion Technique Computer Science Essay The Data transmitted comes in many forms and it is used for more than one application. Communications should be done secretly. Secret communication varies from level of security needed such as banks , in credit card payments and secured communication related to corporate systems .Steganography is an art of embedding a secret message into a normal message. Steganography is used in watermarking for protecting data copyrights .Unsurprisingly, methods of Steganography change because innocuous spam contents are growing frequently by embedded texts Cryptography is technique used to make secret message scribbled for third party and are normally used in WEB. The encrypted message is targeted by attackers in cryptography because it hides the message content. An another data hiding technique known as watermarking used for embedding and hiding, some symbol data or digital manifest in the digital valuable data like photo picture, digital movie, musical sound etc. Watermarking purpose is mainly used to protect ownership or copyrights of the data. In this technique, hardness of embedded evidence and hidden evidence are very small and is important. In this technique the important information is present in external information which can be seen. In the Steganography technique, confidential information made invisible for a human eye by embedding it as a dummy data such as a speech sound and a digital image. Steganography contains another research topic called as steganalysis which is used to find a stego file from the available files. Steganalysis is used in detecting suspicious image file. The suspicious image files are embedded with the crime associated information The information hiding capacity is limited in traditional Steganography. These techniques can hide 10% or less than 10% data of a carrier data. The principle of these techniques is to replace frequency components of carrier or to swap LSB bits of multivalued image with secret information. In Steganography, image is used as a carrier data and it embeds secret information in bit planes .In Steganography, replacing noise like reg ion without disturbing the image quality is termed as B.P.C.S Steganography..BPCS Steganography is known as Bit plane complexity segmentation Steganography. BACKGROUND HISTORY: Steganography is derived from a Greek word which means as a covered writing or hidden writing. In Steganography stegos means cover and grafia means writing. THEORY: Steganography used to hide confidential information from human eyes by embedding it in a carrier data such as a digital image or a speech sound. A carrier data is consists of color images having RGB color components in a multi-bit data structure. The embedded information is evoked by means of special extracting program and key .The techniques of Steganography different from file camouflage or file deception technique. File deception is used for hiding secret data in system file and it almost looks as a Steganography. But, it is a one of easy method to disguise an secret-data file as a regular file and is possible in files which have dont care option. For example, Word file or JPEG image OR MPEG will allow for adding an extra data (extension) at the end of a usual file. After adding an extra data, the JPEG image, word file or MPEG looks as original image and original sound, or document on system.People may think this is due to Steganography. The lengthy files are easily noticed by engineers. Therefore file deception and Steganography are different. The Steganography softwares that are available in the market are based on file deception. In Steganography, if output file size is increased by embedding the information then the program is called as File deception. A secret data can be made unreadable by encrypting the data. The secret data should be encrypted to make it unreadable for third party. With the help of data encryption, secret data can be safe. Data encryption depends on a data scrambling and it uses a secret key. Data encryption can create a doubt to the people that owner of the data is hiding something in an image. In data encryption we can find easily that he is hiding something in a image. Therefore encryption of data is not enough. Steganography is the solution for data encryption. There are two types of data in Steganography .they are secret data and carrier data. Secret data is very valuable when compared to the carrier data. Carrier data is a type of dummy data which is not so important but it is needed. The data which is embedded is called as stego data. If we want to recover the secret data , we can extract that data from stego data. We need a special program or a key for data extraction.. The carrier is image data which has color components of red green and blue colors in 24 bit pixel structure. The figure below shows an example of carrier image and stego image. The secret data is embedded in stego image. http://www.datahide.com/BPCSe/images/stegano-scheme.jpg Steganography is a method of hiding the secret data by fixing it in media data .For example in the figure a secret data is embedded but we cant find in which place the secret data is embedded. The data which is embedded will be very safe in the Steganography because it will hide content of the message and location of hidden image. There are many methods to embed the data .but; it is very hard to find about the method used in embedding the message.. Steganography collaborates with cryptography to embed the encrypted data safely. In Steganography, Stego data will not have any evidence about the embedded data. The Steganography user should discard the original carrier data after embedding such that it will not allow comparison of stego and original data. Embedded capacity should be larger. BPCS method is the method available method for image Steganography. If anyone detect the Steganography image, it is very difficult for him to retrieve the hidden image. There are three basic ways to hide a message in image. They are Injection, substitution and generation. Using Injection method we can find in which place data to be inserted and using substitution we can find least significant bits for hiding the message. Using generation method we can create a new file based on the hidden information. Method of implementation: Least significant bit insertion is one of the important methods of implementation. In this method , the LSB bits of byte is altered so that it form bit string and represents a embedded file. By changing the LSB bits, it will cause some small differences in color which are not noticeable to human eye. After that an image is compressed and a text message is hidden in image .In LSB method, LSB bits of the covered image are changed to form embedded information. Embedding a message into cover image will result a stego image. For normal vision, the appearance of stego image will be same as cover image because of small changes of pixel values. Therefore there is no significant difference. The embedded message is sequentially embedded in covered image so that it is simple for other third party to recuperate the message by retrieving the pixels consequently which starting from the first pixel of the image. Steganography uses a key which as a better security. It is difficult to recover the emb edded image without valid key. LEAST SIGNIFICANT BIT INSERTION Least significant bit insertion is the common technique used in Steganography. In LSB method, an image is used. An image is more than strings and string of bytes. Each byte in an image represents different colors. The last few bits in a color byte do not hold much significance as the first few bits. Therefore only two bits differ in last few bits that represent a color which is undistinguishable to human eyes. In LSB method, least significant bits of a cover image are altered such that we can embed information. The example shows how letter A is hidden in first 8 bytes of 3 pixels in a 24 bit image. Since the 8 bit letter A requires only 8 bytes to hide it, ninth byte of the 3 pixels used to hide the next character of the hidden message. Example shows that in a 24 bit image, letter A can be hidden in first 8 bytes of 3 pixels Pixels: (00100111 11101001 11001000) (00100111 11001000 11101001) (11001000 00100111 11101001) A: 01000010 Result: (00100110Â  11101001 11001000) (00100110Â  11001000 11101000) (11001001Â  00100110Â  11101001) The five underlined bits are the 5 bits which were altered. With LSB insertion technique, on an average half of the bits of an image are changed. A is a 8 bit letter and requires 8 bytes for hiding. The ninth byte of 3 pixels is used for hiding next character of secret message. The slight variations of this technique allows a message to embed into two or more least significant bits per bytes, and increases the information hidden capacity of the cover object .but cover object is degraded and easily detectable.LSB insertion is easy to implement and is also easily attacked if the modifications are done wrongly. Improper modifications in color palette and normal image calculations will demolish hidden message. Image resizing and image cropping are some examples of image manipulations. Applications of Steganography: Steganography is applicable the following areas. 1).Private communication and secret data storing. 2).Security of data. 3).Accessing the control system for distributing the digital content 4).Media data base systems. The application area of Steganography differs based on the features utilized in a system. 1).Private communication and secret data storing: The secrecy of embedded data is important in this area. Steganography provides capacity for hiding the existence of secret data and Steganography makes very hard to detect the embedded data in a image and Steganography strengthens the encrypted data. In Steganography, select a carrier data according to the size of embedded data. Carrier data should not be effective. Now embed the secret data using an embedding program with the help of a key. To recover the embedded data, an extracting program is used with a key. Before starting the communication in this case, Key negotiation is used 2).Security for a data: Steganography is used in military applications for maintaining the secret data .In military secret information should be very secure to avoid sudden attacks on them from enemies. Steganography can hide the existence of contents of data but it cannot hide the presence of data. Data should not be larger than carrier image .Steganography strengthens the secrecy of the data. Fragility of the embedded data is advantage for this application area. Embedded data can be rather fragile than robust. But embedded data is fragile in most of the Steganography programs. No one can change or tampered the data .If anyone changes or tampers the data, and then it can be easily detected by the extraction program. 3). Accessing the control system for distributing the digital content : In this application, embedded data is explained to publicize the content. Here embedded data is hidden data. Digital contents are being commonly distributed by internet. Some music companies release the music for free in some web sites and in some sites it charges for the music downloads. Digital contents are equally distributed to user who accesses the web pages. Even it is possible to send digital content to e-mail messages it takes more time. We can to upload any content on the web page; we can issue a special access key to extract the content. In Steganography a prototype of an access control system is developed for distributing the digital content through internet. This can be explained by following steps. 1).The content owner will classify his digital content in a folder and embeds the folder according to Steganography method by accessing the folder access key and uploads embedded content on web page. 2).On the web page, owner will explains the contents clearly and publicises it worldwide and gives his contact information on web page. 3).The owner will receive access request from the customer who visited that web page. Then owner creates an access key and provides it to the customer for free or charge. 4).Media database systems: In this type of application secrecy of data is not important, converting two types of data into one data is important. Photos, Pictures, movies and music will come under media data. For example the media data for a photograph will contain about the title of the photo and date and time of a photo and it also contain about the camera used to take that photograph. Data hiding in .bmp images: There are several formats exists for an digital image. .BMP, JPG, GIF are some formats .Each format is associated with advantage and disadvantages. Because of its simplicity, windows BMP file offers more advantages. It has an advantage of widely spreader and the information contained is minimum .Bmp file is a binary file.bmp file is divided into four sections such as file header, color table, image header and pixel data. To know about size of the image file header are used and also to learn where actual image data is located within the file. The Image header gives information about the image and its data format such as width and height of the image. Image header also gives information such as how many bits are used per pixel and checks whether the image data is compressed data or uncompressed data. Depending on the image data, color table will be present. When color table is not present, a set of bit masks are used to extract the color information from the image data. When dealing wi th 24-bit image, color table is not present. When dealing with 8-bit image, color table consists of 256 entries. Each entry consists of four bytes of data. In these four bytes of data, first three bytes are blue, green and red colors values .The fourth byte must be equal to zero because it is not used. In 8-bit format, each pixel is represented by single byte of the data which is index in to color table. In 24-bit format, each pixel I represented by RGB component values .The pixel data holds entire hidden data and there are changes by one pixel value either positive or negative. IMAGES IN MATLAB The data structure in MATLAB is array, it is set of real or complex elements. MATLAB suits better in representing the images. images are stored as two dimensional array or matrices where each element of matrix determines one pixel in displayed image. DIGITAL IMAGE PROCESSING Image is a two dimensional function f(x, y). Whereas x and y are spatial co-ordinates. The amplitude of f at f(x, y) is called as intensity image. Image is defined as digital image if values of f, x, y are of discrete quantities. Digital image processing is defined as a process of a digital image using a digital computer. The digital image contains finite number of elements. Each element as its location and a value and elements are called as pixels. Image plays an important role in human life. The analysis of an image depends on vision and image processing. At one end of vision there are no clear cur boundaries in continuum. Let us consider three types of process in continuum. They are low level, mid level and high level process. Low level process involves operations like reduction of noise, sharpening of image, and adjustment of contrast. Mid level operations involve segmentation, object description. These operations will be helpful in reducing a object and for classifying object. In mid-level process , inputs are images and output are extracted from input images. High level processing involves operations like ensembling of objects and some functions that are involved with human vision . Definition for an image: Image is a two dimensional function f(x,y) , x y are spatial co-ordinates. Amplitude of f at x, y is called as intensity of image. Gray scale image: It is function of two spatial co-ordinates of image plane. On image plane I(x,y) is intensity of image at x,y. Color image. Image is represented by three functions R, G, B. RGB is a three colors red green and blue. The image as continuous amplitude and is continuous with x, y. The amplitude of image should be digital for converting an image to digital image. Conversion of co-ordinate values of an image into digital values is called as sampling. Converting the values of amplitude into digital values is called as Quantisation. Coordinate convention : Sampling and quantisation result a real number matrix.The digital images are represented in two ways.By sampling f(x,y) , an image with M rows and n columns resulted and the size of that image is MxN .The coordinate values are of discrete quantities.In many books that are related to image processing it is mentioned that origin of image is at (xylem)=(0,0) .the next coordinates are at first row of image and it is given as (xylem)=(0,1).Here it is importent to keep note that (0,1) is used to signify second sample along first row. Toolbox uses the word race instead of using xylem to indicate rows and columns. Toolbox employs spatial coordinates less frequently. Image as matrices: A digital image is represented by a function F(0,0) f(0,1)f(0,N-1) F(1,0) f(1,1)f(1,N-1) F(xylem)=f(M-1,0) f(M-1,1)f(M-1,N-1) In above equation f(M-1,N-1) can be defined as a digital image. In this array , each element is called as image element and picture element. In MATLAB, digital image is represented as F(1,1) f(1,2)f(1,N) F(2,1) f(2,2).f(2,N) . . F=f(M,1) f(M,2) ..f(M,N) If f(1,1)=f(0,0) then it represents they are identical. F(x , y ) denotes that elements are located in row p and column q. Lets take an example f(8,7). Here elements are located at eight row and ninth column. In a MxN matrix, M denotes number of rows and N denotes number of columns. Here MxN matrix is called as column vector and 1xN matrix is called as row vector and 11 matrixes is defined as a scalar quantity. In matlab, matrix is stored variables A, real array, and so on .The variables in matlab matrix should contain letters and numbers. F(x,y) is a roman and Italian notation that are used in matlab for mathematical expressions. How to read image in MATLAB: The function imread is used to read an image in MATLAB. The syntax for reading an image is imread(filename).The different formats used in MATLAB are TIFF PNG JPEG XWD GIF BMP .TIFF is a tagged image file format and is represented as .tif and .tiff. PNG is a portable network graphic and it is represented as .png. JPEG is joint photograph experts group and are represented as .jpg and .jpeg. GIF is a graphic interchange format and are denoted as .gif. BMP is bitmap window and are recognised as .bmp. XWD is X window dump and are recognised as .xwd. The filename contains image file EXAMPLE : >> f = imread (8.jpg); In this command, it reads jpeg image into image array f and single quote delimits the filename of a string. In a MATLAB, semicolon is used for suppressing output and if we wont use semicolon it displays result in that line. The symbol >> denotes that starting of a command. This symbol is shown in matlab command window. In command line, path is not included in filename. Imread reads the file in a current directory. If it is not read in the current directory window, we can find that file in MATLAB search path. We can read an image from directory that includes full path or relative path in filename. Example : >>f=imread (E:jaichestxray.jpg); Therefore it reads the image from jai folder on E drive >>f=imread(.jaichestxray.jpg); Therefore it reads an image from a sub directory jai of current working directory. Current directory displays MATLAB current working directory on matlab desktop toolbar. TIFFS, JPEG, GIF, BMP, PNG, and XWD are the popular image formats and these formats are supported by imread and imwrite functions. In a image the dimensions of rows and columns are given by size of a function >>size (f) In MATLAB this function is useful in determining the size of an image. >>[M,N]=size(f); The syntax returns number of rows and columns. M is number of rows and N is number of columns and f gives the size. How to read a graphic image: In a graphic file format, imread can be used to read an image. For storing an image pixel , most of the formats uses 8 bit and are stored as class uint8 in matlab and if the file supports 16bit data , MATLAB stores image as class uint16. How to display image: The function imshow is used for displaying an image in MATLAB. The syntax for displaying a image is imshow(f,g) In the above syntax f is array of image and g is used for displaying number of intensity levels. G defaults to 256 levels if it is omitted by syntax imshow(f,{low high}).If the values are less than are equal to low then it displays as black and if values are greater than are equal to high then it displays as white. If the values are not less than and not greater than and are in between then it displays as intermediate intensity value by defaultly. Therefore the final syntax is Imshow(f,[ ]).The variables which are high will have maximum value and low variables will have minimum value. The function imshow will display positive and negative valued images. Pixval function are used for displaying the intensity values individually. Pixval function displays cursor on the image. In a figure window, Move the computer mouse on the image so that intensity values and position of cursor is displayed. The color components such as red green and blue are displayed when working with color image. The Euclidean distance of initial and cursor positions can be displayed by pixval and this can be done by clicking left side button on mouse.Click the x button for closing the window. >>imshow(f) If there is a semicolon at ending, it will not have an effect so it is exception of using semicolon. MATLAB can replace an image with new image by displaying another image using imshow. Use the function >>figure, imshow(g) for keeping first image as output second image.The statement >>imshow(f),figure , imshow(g) is used for displaying both and first and second images .If different commands delimits commas and semicolons then more than one command is written on the line. To suppress the outputs of a screen from command line , the semicolons are used. HOW TO WRITE IMAGE : The function imwrite is used for writng an image in MATLAB. The syntax for writing an image is Imwrite (f,filename).In this syntax , filename contains a string .file extension format should be a recognised format. >>imwrite(f,patient10_run1,tif) Or >>imwrite(f,patient10_run1.tif) This command is used for writing f to a TIFF file patient10_run1:.In current directory window imwrite will save the file if the file does not have information about the path. Depending on the selected file format ,imwrite is having other parameters. The most important formats are JPEG and TIFF .so it is important to focus on these two file formats.The syntax imwrite is applied to jpeg images Imwrite(f,filename.jpg,,qualityq) Here q is the integer and its value ranges between 0 and 100.In compression of jpeg image ,if the number is less than the degradation will be higher. This can be explained by the following example. Here q=25 Then the syntax is >>imwrite(f,bubbles25.jpg,quality,25) If an image is has q=15 then it has false shape which is hardly visible.this effect pronounces as q=5 and q=0.compress the image with q=25 for an expectable solution .compression can be achieved by obtaining details of image file by using imfinfo The syntax is Imfinfo filename Filename refers the complete filename of image that is stored on disk.this can be explained by following example >>imfinfo bubbles25.jpg It displays output in following way. filename: bubbles25.jpg and filemoddate :08-jan-2009 12:30:25 and filesize :13849 format:jpg format version : width : 715 height : 687 bit depth :8 color depth :grayscale format signature: comment: { } The filesize is expressed in bytes. The number of bytes in original image multiply width and height by bit depth and divide the obtained result by 8 therefore we get result as 491205.We can obtain the ratio of compression by dividing the file size.(491205/13849)=35.46 therefore compression ratio is achieved and it is 35.46.Maintain the quality of image consistently. The reduction of stoage space transmits 35times of the uncompressed data per unit time. Iminfo displays the information field and are captured by a variable for some computations. >>k=iminfo(bubbles25.jpg); Here k is assigned to a structure variable. The variable k as information and it is generated by command imfinfo. The information that is generated by imfinfo command is added to structure variable by a field that are separated from k by dot. The height and width of a image is stored in k.height and k.width Consider the structure variable k for changing the ratio of compression bubbles25.jpg >>k=imfinfo(bubbles25.jpg); >>image bytes=k.width*k.height*k.bit depth/8; >>Compression_ bytes =k.filesize; >>Compression_ ratio=35.16 Imfinfo can be used in two different ways. One method is type imfinfo bubbles25.jpg at prompt then it displays information on screen. Second method is type K=imfinfo(bubbles25.jpg) then it generates the information that are stored in k variable. The two different ways of calling the function imfinfo is an example of command_function duality. In general imwrite syntax is applied to tif images only Imwrite (g,filename.tif,compression,parameter resolution,[colres rowers] The parameter will have one of the principal values such as none it indicates no compression and pack bits indicates compression of pack bits and ccitt indicates compression of ccitt. By default ccitt is for binary images.1*2 is an array and it contains two integers that gives resolutions of row and column in dot per unit. If the dimensions of image are in inches then colres will have number of dots per inch in vertical direction and it is same for rows in horizontal direction . >>imwrite(f,sf.tif,compression,none,resolution.[300 300]) Multiply 200 dpi by ratio 2.25/1.5 then we get 30dpi to determine values of a vector.if we compute manually , we can write >>res=round(200*2.25/1.5); >>imwrite(f,sf.tif,compression,none,resolution,res) This syntax is like an argument for nearest integer. The number of pixels is not changed by using these commands but there is a change in scale of the image. These processes are useful in controlling image size without loosing its resolution. On matlab desktop , it is necessary to export images to disk. It is true with plots. In a figure window, there are two ways for exporting the contents. First method is , in a figure window select file option in menu and then choose export option. Using this option user can choose the location, format and a filename. Using print command we can obtain the control on export parameters.The command isprint-fno-dfileformat-rresno-filename. In figure window no refers to the number of a figure and file format refers to file format that are available. The resolution in dpi is referred as resno. The filename is used for assigning a file. If we type print at the prompt, MATLAB prints contents of the displayed last figure window. How to write a graphic image: In a graphic file format, imread can be used to read an image. For storing an image pixel , most of the formats uses 8 bit and are stored as class uint8 in matlab and if the file supports 16bit data , MATLAB stores image as class uint16. In a graphic image format, the function imwrite is used to write an image to graphic file .The basic syntax imwrite takes image variable and image filename. How to resize an image: The function imresize is used to change the size of image. Using the imresize function we can fix the output size Image cropping: The function imcrop is used for cropping an image. Using imcrop, we can crop the rectangular portion of an image. The imcrop function is used for displaying an image in a figure window and we can crop the image in a figure window. DATA CLASSES: The pixel values are not limited to integer values in matlab. The MATLAB supports various data classes for representing the pixel values. There are three types of data classes .they are numeric data class and char class and logical class. Char class is the ninth entry in data classes and logical data class is the last entry. The numerical calculations in MATLAB are done in double quantities so data classes encounters frequently in image processing applications. The class unit 8 is found when reading the data from a storage device and 8 bit images are commonly found .The two data classes logical data class is of less degree and unit 16 forms the primary data class. Ipt functions support all data classes. To represent a number, data class double requires 8 bytes. Uint8 and int 8 requires one byte and uint16 and int16 requires 2 bytes. The various data can be described as follows. The data class double can be described as double_precession, floating_point numbers. Uint8 ranges from [0, 255] and it is an unsigned 8bit integer and it is of one byte per element.Uint16 is a unsigned integer and ranges from [0, 65535] and it is of 2 bytes per element. Uint 32 is an unsigned integer and ranges from [0, 4294967295] and it is of 4 bytes per element. Int 8 is an 8bit signed integer and it is of 1 byte per element an d ranges from [-128,127]. Int 16 is a 16 bit signed inter whose is range is of [32768, 32767] and it is 2 bytes per element. Int 32 is a 32 bit signed integer of range [-2147483648 , 21474833647] and it is of 4 bytes per element. Single is a single_precession floating_point number with the values and ranges 4 bytes per element. Char is called as character and it ranges of 2bytes per element. Logical is a data class, whose values are 0 to 1 and it is of 1byte per element. Char data class holds characters in Unicode representation. The char string is simple 1*n array. The values of logical array are 0 and 1 .Using logical function each element is stored in the memory. TYPES OF IMAGES There are four types of images that are supported by MATLAB. They are Intensity image, binary image , indexed image , R G B image. Most of the image processing operations are performed by binary image or intensity image. Intensity image: Intensity image is a data matrix and its values are represented within some range by intensities. The Intensity image is stored as a single matrix in MATLAB In intensity image, image consists of intensity or gray scale values. Intensity images are represented by arrays in matlab. In intensity image, images are repr

Is Aristotle the Father of Logic

I believe so. Aristotle became known as the Father of Logic by demonstrating that logic was more than just an equivalent to verbal reasoning but an important tool of investigation, a way to learn everything about everything. He was the first to introduce scientific thought into daily processes. Even today, with hundreds of advances in technology and available resources, scientists find that observations he had documented two-thousand years ago are correct. For twenty years Aristotle studied with Plato and became a prominent figure at his academy. But yet after so many years of collaboration between the two, many people including Plato’s nephew Speusippus believed that Aristotle’s ideals varied greatly from Platos and indeed they did. Plato presumed that the â€Å"ideal† form of an person or animal is the result of a â€Å"sensory† world and that every man knew and understood his place in life. Whereas Aristotle believed that the â€Å"form† consisted of several characteristics together as a whole, which eventually was proven and known as DNA (deoxyribonucleic acid) as well as believing that a man should create his own place in the world. Consequently, Aristotle left the academy after Plato’s death. Several years later he developed his own school known as the Lyceum at which he taught for thirteen years in a rather peculiar fashion. His lectures were offered to those that were willing to listen as he paced up and down the peripatos outside the school. His works included a vast array of subject matter including physics, biology, psychology, politics and more. In the subject of Logic, he developed the foundation of categories, a way to classify each element of an argument. He further demonstrated that the core of logical thought is a sequence of three propositions in which the first and second imply the last, known as a syllogism. These thoughts have stood the test of time and have only been slightly revised throughout the centuries. It is believed that Aristotle wrote four-hundred books in his lifetime. However, his work was hidden from the world for many, many years when he died in 322BC. Only a portion of them were discovered in 100BC, unfortunately ruined by dampness and moths. Originally taken to Athens and then to Rome, his works gained interest and were used as textbooks by Roman scholars and are still an important influence in learning today.
