DIFFERENCE BETWEEN ANALYSTS AND STATISTICIANS In today’s digital landscape, data has become one of the biggest and most important assets for almost all organizations. Data can be fetched from anywhere and it’s actually transforming the way we live. Statistics and analytics are two branches of data science. Analysts specialize in exploring what’s in your data, statisticians focus more on inferring what’s beyond it. Let’s have a look at basic analytics? Try googling the weather. Whenever you use a search engine, you’re doing basic analytics. You’re pulling up weather data and looking at it. What expert analysts do? They’re all about taking a huge unexplored dataset and mining it for inspiration. Analysts are lightning-fast coders who can surf vast datasets quickly, they are data storytellers. Their mandate is to summarize interesting facts and to use data for inspiration. In some organizations those facts and that inspiration become input for human deci...

What is green cloud? Green cloud is a word that refers to the possible environmental benefits that IT services delivered over the internet can offer. Green means environment-friendly while the cloud represents the internet service, delivery model.  Green computing is defined as the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems such as monitors, printers, storage devices, and networking and communications systems-efficiently and effectively with insignificant or no impact on the environment. Goals of green cloud computing The main goal of Green Computing is to adopt those Information Technical products that creates minimal carbon footprint. The goals of green computing are similar to green chemistry like to: a)      Minimize energy consumption. b)      Purchasing green energy The steps that lead to fulfilling of these goals include bui...

BIOMETRICS: We live in a world today, in which technology moves at a very rapid pace. Many of these technological advances can be used to make our everyday lives easier and safer. One of these new technologies is Biometrics .   Biometrics is the process of measuring a person’s physical properties. This would include measuring things like fingerprints, retinas, vein structure on the back of the hand i.e. hand geometry, voice pattern , facial recognition, and many other things. It is a very important topic because it would create better security precautions for certain places that need to be secure. Biometrics will make our society safer by only allowing authorized people out of secure facilities and by keeping the unauthorized people out. Biometrics is used in many places and there is a bright future for them.  Coca Cola has recently replaced the time card system with hand scanning machines.  Facial Recognition system at IGI, Delhi. Biometric attendanc...

Brain-Computer Interface (BCI)  are devices that enable its users to interact with computers by mean of brain-activity only, this activity being generally measured by ElectroEncephaloGraphy (EEG).Electroencephalography (EEG) is a physiological method of choice to record the electrical activity generated by the brain via electrodes placed on the scalp surface.Functional magnetic resonance imaging (fMRI) measures brain activity by detecting changes associated with blood flow. The reason a BCI works at all is because of the way our brains function. Our brains are filled with neurons, individual nerve cells connected to one another by dendrites and axons. Every time we think, move, feel or remember something, our neurons are at work. That work is carried out by small electric signals that zip from neuron to neuron as fast as 250 mph . The signals are generated by differences in electric potential carried by ions on the membrane...

Amazon NHS Association An association for elderly people, blind people and other patients who cannot easily search for health advice on the internet to access the information through the AI-powered voice assistant Alexa.  Recently, Matt Hancock announced a new collaboration between the NHS and Amazon, which paired expert medical advice by NHS with amazon’s market-leading Alexa device. People who need medical information can get advice directly from NHS which is more accurate, reliable and safe. Privacy campaigners have expressed their concern for the data, they said that the data could be stored and used to sell targeted ads aimed at customers. Silkie Carlo, director of Big Brother Watch, said: “Amazon’s Alexa records what people say, stores recordings in data centres we know nothing about and exploits our data for profit. This scheme will likely result in people being profiled and targeted by data brokers based on their deeply personal health concerns”. ...

Watch out for that bird! Imagine you are skydiving, you are visiting one of the most beautiful countries in the world and you want to share that experience with your loved ones and friends. Why not send a postcard? Oh wait, you’re already back from the trip by the time that postcard has reached, or it got lost in the mail. If only there was an alternative. This isn’t 1990. You have a platter of platforms to share your adventure. Webster’s dictionary defines social media as-“ forms of electronic communication (such as websites for social networking and microblogging) through which users create online communities to share information, ideas, personal messages, and other content (such as videos).”In simple words, social media, are various public platforms where people can share their views, stories, etc. with the help of various mediums. Starting with websites such as MySpace, Orkut, and Facebook, etc. it is now estimated that there are about 200 social media websites in ...

WILL HUMANS BECOME CYBORGS IN FUTURE? Cyborgs are amongst us already. Not those that exist in our imaginations or movies, but a more efficient variety that is different from the non-modified humans. As part of the growing ‘transhumanist’ movement, people have also implanted sensors into their bodies in order to push the limits of human experience. As new technologies such as artificial intelligence and 3D printing bring ever more possibilities, are we about to lose the bound ary between human and machine? WHAT EXACTLY IS A CYBORG? The word cyborg is an abbreviated version of ‘cybernetic organism’.  A cyborg is a living being having both cellular and mechanical/electrical parts that either repair or improve the organism’s functioning.  Robots and droids do not fall into this category. People with the most common technological implants, such as prosthetic limbs, pacemakers, and cochlear implants, can also be considered cyborgs. People who receive organ implants...
