Identity and Access Management is a business process framework that helps to manage electronic or digital identities. IAM focuses on restricting user access to critical information until and unless they are authorized to. Such authorizations are provided based on their roles and the privileges assigned to the role. To reduce both internal and external data breaches, IAM is extremely important. In recent days, it is considered as one of the most important quality parameter for all software… Show more

Hadoop implements a computational paradigm named Map/Reduce, where the application is divided into many small fragments of work, each of which may be executed or re-executed on any node in the cluster. In addition, it provides a distributed file system (HDFS) that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both Map/Reduce and the distributed file system are designed so that node failures are automatically handled by the framework. Show less

Emotions have been a point of interest for researchers for centuries since there is no definitive answer to the question “What is emotion?” Some says that emotion is an instinctive or intuitive feeling as distinguished from reasoning and knowledge. But still as emotions are difficult at best to define, our attempt is to understand the user’s emotional state and henceforth, analyze it. Hand vein thermography, being 99.25% accurate in measuring human emotions, best fits our purpose. It has… Show more

Emotions have been a point of interest for researchers for centuries since there is no definitive answer to the question “What is emotion?” Some says that emotion is an instinctive or intuitive feeling as distinguished from reasoning and knowledge. But still as emotions are difficult at best to define, our attempt is to understand the user’s emotional state and henceforth, analyze it. Hand vein thermography, being 99.25% accurate in measuring human emotions, best fits our purpose. It has minimum effect on user’s interaction without causing distress or interruption. Hand sweat and micro-perspirations are capable of processing even the most subtle emotional responses to moment to moment or minute to minute life events. Thermography brings skin temperature recording into the space age. Instead of “loading” the skin by using contact thermometers, such as thermocouples, and obtaining inaccurate temperature readings or a record of an isolated area, thermographs furnish thermal maps of large areas of skin surface without touching the subject. They not only offer pictorial representations of skin temperatures whose interpretation opens entirely new fields for the study of human emotions but also, detect minute change in temperature. Since the radiation of heat by human body is a unique characteristic of individual, unchangeable by surgery and invariant to time even in case of identical twins, it is often used for security purpose to circumvent fraudulent attempts. This paper reviews research available on hand vein thermography as a biometric and suggests a system whereby human emotions could potentially be measured during software use. Show less

Among the various types of biometric personal identification systems, DNA provides the most reliable
personal identification. Humans have 23 pairs of chromosomes containing their DNA blueprint. One member of each chromosomal pair comes from their mothers; the other comes from their fathers. Every cell in a human body contains a copy of this DNA. The large majority of DNA does not differ from person to person, but 0.10 percent of a person's entire genome would be unique to each… Show more

Among the various types of biometric personal identification systems, DNA provides the most reliable
personal identification. Humans have 23 pairs of chromosomes containing their DNA blueprint. One member of each chromosomal pair comes from their mothers; the other comes from their fathers. Every cell in a human body contains a copy of this DNA. The large majority of DNA does not differ from person to person, but 0.10 percent of a person's entire genome would be unique to each individual. This represents 3 million base pairs of DNA. Genes make up 5 percent of the human genome. The other 95 percent are non-coding sequences, (which used to be called junk DNA). In non-coding regions there are identical repeat sequences of DNA, which can be repeated anywhere from one to 30 times in a row. Short sequences of base chemicals called “short tandem repeats” or STRs, repeat over the length of the DNA molecule. The number of times these STRs repeat is unique to each individual. It is intrinsically digital and unchangeable while the person is alive, and even after his/her death. Pattern matching in a DNA sequence or searching a pattern from a large data base is a major research area in computational biology. Show less

Computers have become an essential part of our lives, both at work and at home. Lack of access to the Internet is as unthinkable in the 2010s as it was extraordinary 20 years before. While computers have helped to reduce the millions of tons of paper and other resources spent on long-term hard storage of information, computers and associated products are causing their own environmental concerns, labelled under the term electronic waste.

Computers have become an essential part of our lives, both at work and at home. Lack of access to the Internet is as unthinkable in the 2010s as it was extraordinary 20 years before. While computers have helped to reduce the millions of tons of paper and other resources spent on long-term hard storage of information, computers and associated products are causing their own environmental concerns, labelled under the term electronic waste. Fortunately, there are things we can do as a society and that are being done by manufacturers to combat the effects of e-waste. Green computing reduces the use of hazardous materials, maximize energy efficiency during the product lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. In 1992, the U.S. Environmental Protection Agency launched Energy Star, a voluntary labelling program that is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies. This resulted in the widespread adoption of sleep mode among consumer electronics. Concurrently, the Swedish organization TCO Development launched the TCO Certification program to promote low magnetic and electrical emissions from CRT-based computer displays; this program was later expanded to include criteria on energy consumption, ergonomics, and the use of hazardous materials in construction.
