Rwanda is a country in central Africa known as “the land of a thousand hills.” The troublesome topography combined with the heavy rainy season from March to May makes any travel, even by car, nearly impossible. So how do people across the country get access to basic healthcare? Lots of countries in Africa and across the world organize healthcare facilities into three basic tiers: hospitals, healthcare centers, and rural outposts. Few people regularly have access to hospitals since most of the population lives in rural areas. So what’s happening to improve Rwandan healthcare?
Recent studies have shown that an always present but generally ignored component in almost every vehicle can leave the user vulnerable to hacking attacks.
Damon McCoy, an assistant professor of computer science and engineering at the NYU Tandon School of Engineering, along with a few students from George Mason University, conducted what is believed to be the first comprehensive security analysis of its kind. They found that MirrorLink, a system with rules that allow vehicles to connect to smartphones, contained an easily accessible liability.
Over the past few years, there has become more devastating terrorist threats across the world which brings technology into question when dealing with airport security. Airport security has not only become much more serious in dealing with passengers through security but very aware of what technology is being used to detect any harmful items that could lead to terrorism.
Once you arrive, it all starts with a long procedure that might seem grueling. Waiting in line for your passport to be stamped, then going through a whole security guard system with full-body scanners. It might seem ridiculous to take off your two year’s shoes because there could be a explosive liquid inside, but that is the world we are living in today. According to the executive director of UK rights group Privacy International, Gus Hosein, “People increasingly expect to be treated like cattle at airports.” Technology has been evolving in airports in the same way like any other technology company. But, this doesn’t mean it is always working. Security and screening methods have quickly adapted to change threats around the world even though it might not seem like these scanners are working.
Airport security has become one of the least popular aspects of travel according to a passenger survey conducted y the International Air Transport Association(IATA). Driving seems like an easier alternative for families who want to wake up and bring whatever they choose in their bags. The use of full-body scanners has been the biggest complaint by passengers in airports. Airports are trying to make this process as efficient and painless as they can without being scrutinized.
Dealing with MRIs at the airport when checking luggage is a whole other problem. But that might change quickly according to scientists at Los Alamos National Laboratory in New Mexico, who have come up with a system called MagRay, based on the scanning technology developed for medical applications. This will improve traffic flow in airports by letting passengers bring liquids in their carry on baggages without having to throw them away.
There are many improvements that are constantly being made in airports to reduce stress from threats or identity stealing. This definitely leads passengers to feel more safe and relaxed while navigating through their travels. Even if superior scanners and smarter systems may seem intense this can lead airport security such as guards to become less evident and make your family have a nice flight home.
On the Student Help Desk, we have a special login to check “tickets” that teachers have put in, and then are “assigned” to us and we can work on them.
As we all know, when we help people to solve their technology problems, there are a bunch of different kind of tickets we need to solve. I am really interested about that because it is really useful in our life. Further more, when we are shadowing with Mr. Laurence, we solve these kind of problems in school. So I want to learn more about that.
A large scale denial of service attack (aka a “DDoS”) has most likely affected your browsing on your favorite websites today. Such sites, such as Twitter, Netflix, Amazon, Paypal, or even Reddit, have been attacked. A DDoS attack, according to USA Today, is when “someone, or a group of people, floods a particular site or service with large amounts of fake traffic in an attempt to overwhelm the system and take it offline.”
The issues have been addressed, and mostly pertained to the East Coast. All should be back online now. For more information click here. Have a wonderful weekend!
Over the years, scientists and researchers have created robots that abilities range from being able to vacuum your living room carpet, to detecting human emotions. Kengoro is a new robot built by a group of Japanese researchers from the University of Tokyo’s JSK lab. The robot is defined as a humanoid; having an appearance or character that is similar to that of a human. Kengoro’s stamina is incomparable to that of other two-legged machines.
Humans generate heat when they preform tasks, so to cool off, their bodies perspire. In robots, overheating can lead to failure. Kengoro can move almost exactly the way humans can with its motors of which it has over a hundred. With these motors generating a lot of heat, the researchers were determined to find a way to cool the robot off. Some common ways were using water pumps, fans, radiators, and heat sinks. However, they wanted a energy conserving, efficient cooling system.
The University of Tokyo lab presented the machine at the Institute of Electrical and Electronics Engineers/Robotics Society of Japan International Conference on Intelligent Robots and Systems, under the title “Skeletal Structure with Artificial Perspiration for Cooling by Latent Heat for Musculoskeletal Humanoid Kengoro.” University of Tokyo’s Toyotaka Kozuki said in an interview with IEEE, “Our concept was adding more functions to the frame, using it to transfer water, release heat, and at the same time support forces.” In order to do this, the team built a water circulation system into the robot’s skull. This system allowed the water to go around the motors to cool them. The water would then evaporate from the heat.
Scientists are now exploring ways to apply this research to clothing. The tiny holes could be used to develop a new type of fabric for increased breathability.
Factory workers in the early 1900’s feared their jobs would be replaced when Ford invented the assembly line, and a lot of them did. Many factory jobs are now becoming obsolete. Few people work in factories except for the people who fix the machines and the drivers who transport the finished goods. But now that machines are becoming more and more advanced and Google is developing a self-driving car, will those jobs exist in 50 years?
Lots of other jobs are being replaced by machines all over the world, such as the ATM you get your money from, vending machines, or the machine answering customer calls for a big company. Robots are now being used in hospitals to transport goods and run errands. Nurses and staff now working in hospitals with the TUG robots report that they now have more time to work with patients and that having more time results in better patient care.
How can robots replace people if they can’t act exactly like people? As of now at least robots are made to follow a specific set of instructions. They can’t recognize facial expressions, detect sarcasm, or be creative. Will people want to watch robots act in plays and movies or have machines clean their teeth? Many people are opposed to change and wouldn’t want to support a robot-based future. Will big companies like Honda and Google still want to make robots accessible to everyone if they think there is a market that wont buy them?
It’s safe to say that for now your job is probably safe. However, looking several years into the future, some might gain popularity among robots and machines. When thinking about what you might want to do for the rest of your life, consider looking into something technology related if you want a steady income.
