French Existentialism is often condemned for its perceived quietist implications. However, closer analysis reveals a preoccupation with philosophy in the former and with art in the latter. Neither was nonsensical or meaningless, but both reveal a rich individualist ethics aimed at the amelioration of the individual and society. It is through their combined analysis that we can view and productively utilise their alignment. Offering new critical aesthetic and philosophical approaches to Dada as a quintessential part of the European Avant-Garde, this thesis performs a reassessment of the movement as a form of (proto-)Existentialist philosophy. The thesis represents the first major comparative study of Dada and Existentialism, contributing a new perspective on Dada as a movement, a historical legacy, and a philosophical field of study.

We have designed a cosine based transformation in each pixel. Thus an 800 x 600 pixel image can contain 14, to create the appropriate pixels where data could be hidden. 40,000 bits (1, 80,000 bytes) of secret data. But using just 3 bits Also the data to be hidden is not sequential but is random from this huge size of bytes is wasting space. So the main based on a password algorithm. This concept is based on both objective of the present work is to hide more than 1 bit at bytes visual and statistical. According to our design we have defined and still get results like LSB replacement (imperceptible two layers of security. Higher layers of security can be message). This objective is satisfied by building new achieved by encrypting the input data to confuse steganalysis.

Huge numbers of them utilized Whatsapp, Twitter, Instagrams, messages and other data media to share their data. The extent of data is enormous. Offering security to the data is likewise significant angle. With a specific end goal to give security numerous Cryptography approaches accessible. Out of them DNA Cryptography is a developing field. In DNA Cryptography the figure content is as DNA arrangements. There are tremendous genomic successions in the real world. Putting away of these genomes in Gene Bank is likewise troublesome.This adds up to tremendous information stockpiling costs, in this manner making the utilization of this information, for example, examination and recovery very difficult. DNA arrangement examination is valuable in differing territories, for example, crime scene investigation, medicinal research, drug store, agribusiness and so on, It is extremely important to address the capacity issue of these exponentially developing information. Present day natural science produces tremendous measures of genomic arrangement information. This is fuelling the requirement for effective calculations for grouping pressure and investigation. Information pressure and the related strategies originating from data hypothesis are regularly seen as being of enthusiasm for information correspondence and capacity. In the present paper the authors proposed the DNA Compression by splitting based on the given length and find whether the subsequence contains palindrome or not.

  • Howard Bergerson
    HOWARD BERGERSON A. ROSS ECKLER Morristown, New Jersey Howard Bergerson was born in Minneapolis on July 29, 1922 to Margaret Jeske, who six years later married Ludvick (or Louie) Bergerson. Howard served in World War 11, and moved in 195 1 to a small house in Sweet Home, Oregon, down the block from a shingle mill where he was employed for over 40 years. In 1967, Howard met Nellie, suffering from multiple sclerosis, with three young children, Gerald age 10, Earl age 8 and Merla age 4. Not wanting to see this family broken up, he married her, exhibiting a nobility of character inexplicable to many (Dave Silverman, Kickshaws editor from 1969 to 1976, wrote me "The poor fellow is the only martyr I know. And I don't even know to what!"). He found Gerald's "disruptive, destructive and criminal" tendencies were too much to deal with, even resorting to hypnosis (with some success) to modify his behavior. By the age of 15 Gerald had left home, to live with relatives. When Merla "fled the coop" in 1982, he had to get a home health aide to watch Nellie while he worked. Nellie died sometime in the 1980s; Howard later married the teenage home health aide, but this apparently did not last long. Howard himself suffered from grand ma1 epilepsy, fortunately well-controlled by medication. When Faith and I visited Howard in the summer of 1979, he was living with Nellie and Merla (the boys by then had left) in straitened circumstances. His somewhat dilapidated house was filled with books which Howard had collected over many years, piled from floor to ceiling (Faith joked that the books in the living room were helping to hold up the roof).

  • Chapter 1 Introduction
    Chapter 1: Introduction Chapter 1 Introduction 1.1. Overview An information system is protected from unauthorized access, modification and destruction by the help of information security. There are three prime concepts for information security which are integrity, confidentiality and availability. Integrity deals with the assurance of that the provided information is trustworthy as well as accurate. Confidentiality refers to the restriction of access or privacy of data though it is not same as privacy. Availability ensures the access of infromation by authorized user depending upon their needs. Cryptography is the process of transmitting information by using other forms of original information for secure communication in the presence of adversaries. Private Key cryptography applies the same key for encryption and decryption. Encrypted text and private key both are shared between sender and receiver. The keys used in receiver’s and sender’s ends may be identical or easy to be derived from one to another. Authentication is the process to validate and ensure the identity of the user. Different user authentication processes are implemented in the last two decades. CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) and OTP (One Time Password) are widely used for user authentication. CAPTCHA is a visual test on the basis of challenge and response to determine whether the user is an object or human. OTP authenticates the user for a single session or transaction. Generally, the server automatically generates the OTP which is a numeric or alphanumeric string of characters. 1 Chapter 1: Introduction Secret sharing scheme is applied for the color image where the color image is divided into N (where N is a positive integer) number of shares.

How the studio idea is specifically meaningful when applied to personal reflection d. The “uncanny” aspect of home as the essence of dwelling AIMS of the introduction: An introduction does not need to be a preview listing ideas to be encountered further in the text. Rather, it is a set-up, a preparation. With the surfeit of self-help literature that floods the market, the reader needs to make a clean break with this kind of quid pro quo thinking. The up-market ideas from psychoanalysis are not difficult; rather, they have been until recently shrouded in technical/professional jargon. The Introduction aims to set up key ideas that will serve the reader for the remainder of the reading project and to establish bonds of trust that will assure the reader that the book is not a series of gimmicks. The reader must accept the invitation to read with adequate awareness of what’s at stake. TOPICS: The peculiarly American idea that you can and should help yourself; the distortion of psychoanalysis into ego-strengthening; the studio as counterpart to the modernized factory. The unnameable: anxiety-fear, an “inner division” and an “outer projection.” The intensification of the Real in the Thing, as impossible-obscene proximity; escape is through fantasy; hence, the world of popular culture abounds in evidence of anxiety-fear’s “extimacy.” The idea of spaces inside of space; the φ as symbol of re- entry and bridge to other topics.
