INTELLIGENCE AGAINST TERRORISM: I thank everybody for visiting my website. This is the 100th article on my website. For this important occasion, I have chosen a topic that is the talk of the town. Everybody worldwide is concerned about rise of terrorism and this article is a small step to eradicate terrorism using our intelligence. _______ _______ Prologue: In February 2001, CIA director George Tenet publicly testified to Congress that “the threat from terrorism is real, it is immediate, and it is evolving.” Furthermore, “Osama bin Laden and his global network of lieutenants and associates remain the most immediate and serious threat.” Nevertheless, the Intelligence Community gave no specific warning of the September 11, 2001 attacks. Although all observers grant that terrorist groups are very difficult targets and that undetected movements of small numbers of their members in an open society cannot realistically be prevented, serious questions remain. Look at […]
INTERNET OF THINGS (IoT): _______ _______ Prologue: The phrase “Internet of Things” was coined by Kevin Ashton an expert on digital innovation in 1999 as the title of a corporate presentation he made at his place of employment, Proctor & Gamble. During his time there, Kevin Ashton came up with the idea of putting a RFID (Radio Frequency Identification) tag on each lipstick and having them communicate with a radio receiver on the shelf to track sales & inventory, and signal when restocking was needed. He theorized that such data collection can be used to solve lots of problems in the real world. The Internet is continuously changing and evolving. The main communication form of present Internet is human to human. The Internet of Things (IoT) can be considered as evolution of Internet that realizes machine-to-machine (M2M) learning. The first version of Internet was about data created by people, […]
DRIVERLESS CAR: _____ _____ Prologue: Karl Benz invented the automobile in 1885. Later that year Benz took it out for the first public test drive and he crashed into a wall. Car crash trend continues till date. In spite of stronger cars, extra seat belts, and air bags, 1.25 million people are killed on the world’s roads every year. What could have prevented the accident? The obvious answer is that you could have — by paying attention. Driver error is the most common cause of traffic accidents, and with cell phones, drunken driving, in-car entertainment systems, more traffic and more complicated road systems, it isn’t likely to go away. But if drivers aren’t going to concentrate on the road, who is? If technology continues on its current course, your car will do the concentrating for you. Automakers are developing complex systems that allow cars to drive themselves. Machines are much […]
ZIKA: ______ _____ Prologue: On 18 April 1947, a rhesus monkey that researchers identified as 766 ran a fever of 39.7°C, about 2°C higher than normal. The monkey was part of a study hunting for yellow fever virus and was living in a cage on a platform built into the tree canopy in the 1.5-kilometer-long Zika Forest, which runs adjacent to an arm of Lake Victoria in Uganda. Three days later, the investigators took a blood sample from Rhesus 766 and injected it into the brains of Swiss albino mice. The mice “showed signs of sickness” after 10 days, and the researchers harvested their brains, from which they isolated a “new filterable transmissible agent.” Come January of the following year, the same researchers trapped mosquitoes from these canopy platforms and took them to the lab, hoping to isolate yellow fever virus. Others had shown that one of these species they […]
SWEATING: _____ _____ Prologue: Sweating is an essential and natural biological process that starts soon after we are born. Sweat is a weak salt solution produced by the sweat glands of skin. These are distributed over the entire body but are most numerous on the palms and soles. Since the time of the ancient Greeks, the significance of sweating has been recognized, whereas our understanding of the mechanisms and controllers of sweating has largely developed during the past century. Heat dissipation is vital for our survival during exercise and heat stress. In humans, the primary mechanism of heat dissipation, particularly when ambient temperature is higher than skin temperature, is evaporative heat loss secondary to sweat secretion from sweat glands. Normally humans produce as much as one liter of sweat per day; however most of this evaporates as soon as it is produced so we don’t notice it. The body produces […]
