Electrical engineering may seem like a boring profession, especially if the first person that comes to mind is the public utility repairman who fixed the neighborhood power grid. I think the radiation will be same or a little more as normal use of mobile phones. The latest solution to the problem of getting video onto mobile phones has come from Samsung. Samsung is producing a special chip which can be installed in a variety of devices including portable video players, lap top computers, and of course mobile phones. A device with this special chip set in it will be able to receive special over he air digital TV signals that are broadcast exclusively for viewing on mobile devices. Right now the plan is for local TV stations to broadcast the digital TV signals for mobile devices (including phones) along side a separate transmission for full sized TV’s. It’s not clear … Read the rest

Businesses allocate a lot of resources in making sure that their systems are secure. Apple includes good parental controls in macOS with Screen Time, and the system that already has a sterling reputation for security has been hardened even further in the latest Catalina version, which keeps the OS and user data on separate partitions. It also provides icons similar to macOS. You can maybe even consider it a Linux clone of macOS. RIOT software by Raytheon can search for the location information embedded within pictures you post. Then it can create a timeline and map, showing where you were and when. If you have a habit of taking pictures and posting them, or if someone traveling with you is doing the same, you could be found via this information even if your phone’s GPS is turned off and there is no OnStar GPS device in your car. However, RIOT … Read the rest

A hobby is a non profitable human choice of act for passing leisure time. But the persistent attacks using any potential or unpatched vulnerabilities of the operating system are leveraged by hackers for their nefarious ends. So the Windows operating system does not come with some inherent flaws that make it more vulnerable than other platforms. It’s just that malicious hackers will try to target Windows over Linux or macOS because of the higher probability of successful attacks, just because of the attack surface and the number of users. Great article. However I don’t think we should fear the technology. Technology is good think but we have to target little but more our behavior, our mental state. If we become a man as we suppose to be, then technology comes as a blessing. But with our today evil mental state I agree with you, we should fear the technology. The … Read the rest

The basic definition of the work an engineer is to apply the principles of science and mathematics to develop economical solutions to technical problems. While wireless capsule technology using tiny cameras are currently the only option for capturing images inside the three- to 10-meter-long small intestine, current devices cannot be tracked in the gut precisely, making it impossible for doctors to pinpoint the site of a cancer, polyp, or hemorrhage. Involuntary movements of the small intestine make it further difficult to determine the capsule’s progress. 4 MAC address spoofing: Most of the time, an ISP registers the client’s MAC address for service and billing services. This can be circumvented easily by MAC spoofing, and it is trivially easy in pfSense, where MAC spoofing is as simple as typing in a different MAC address for a network interface. This can be handy if you want to force the ISP’s DHCP server … Read the rest

Well said that the ‘contemporary society is nothing but a technology juggernaut’ and the phenomena is driven and shouldered by engineers. While other technological inventions may have had already been developed prior to the foundation of science, “technology” is not yet a proper term for such. The word technology, after all, is always correlated with science and both science and technology are mutually inclusive to one another, strictly speaking in terminologies. Computers of today, however advanced they may seem, have had its origins in humble beginnings. Socializing: People access the Internet to socialise and to connect with other people with similar interests. The rise of social media has played a big role in making the Internet more popular than ever. Using the new technique, a neuroscientist can order a design which the engineering team can transform into a computer model which feeds instructions to the printer. The printer then applies … Read the rest

Advanced Engineering Mathematics Book for III semester students. Sensors are specialized electronic devices that detect changes in quantities such as temperature , electrical power levels, chemical concentrations, physical position, fluid flow, or mechanical properties like velocity or acceleration When a sensor responds to change, it usually requires a transducer to convert the quantity the sensor has measured into electrical signals that are translated into printouts, electronic readouts, recordings, or information that is returned to the device to control the change measured. Specialized resistors and capacitors are sometimes used as combined sensors and transducers. Variable resistors respond to mechanical motions by changing them to electrical signals. The thermistor varies its resistance with temperature; a thermocouple also measures temperature changes in the form of small voltages as temperatures are measured at two different junctions on the thermocouple. Usually, sensors produce weak electronic signals, and added circuits amplify these. But sensors can be … Read the rest

The history of gadgets spans as far back as humanity itself – since hominids began creating tools to make their lives easier. So here are a few ideas for projects. The simplest experiment with electricity might be an exploration of conductors versus insulators. A conductor is simply a material through which electricity will flow with little resistance; an insulator prevents electricity from flowing. This can be tested by creating a simple circuit with a battery and a light bulb. If a material completes the circuit, the light bulb will luminesce, indicating that it is a conductor. Most metals are conductors, while most nonmetals are insulators. Therefore, it will not be a surprise to see that silver and copper are conductors, while cotton and glass are insulators. However, you may be surprised by the results of lead (a metal) or graphite (a non-metal). Epoxy molding engineering plastics mainly include epoxy molding … Read the rest

Solar energy holds the best promise for a future without electric bills, and enough electricity to power any device needed, anywhere. They’ve become the ultimate customer-employee model and have completely shifted the course of traditional employment. Without Uber, you wouldn’t have Airbnb and other customized, personal services. In terms of visual appeal, Linux has already come a long way. My Ubuntu PC, with the Beryl windows manager installed, is already more visually engaging than any Windows Vista or Mac OS X machine. What’s left to do is to make Beryl less painful to install.

If you are a Windows user like most people out there than you might have been thrilled after you heard that Microsoft came out with a brand-new operating system and that this operating system promised to solve many of the issues found in Windows Vista while improving on its look and performance. Some people who have postural kyphosis may benefit from pain relief by strengthening their abdominal muscles. Exercises like the abdominal press may provide some amount of correction to a dowager’s hump over time, but the AAOS reports that significant changes are not likely. To maximize results, use a variety of machines and workouts that target your entire body, and don’t be afraid to try new types of equipment. There are several exercise machines that are forgotten or overlooked because people don’t know how to use them. Cardio equipment like the upper-body ergometer, rowing machine and stepmill can still … Read the rest

Advanced Engineering Mathematics Book for III semester students. Before you add an video file to your web page, it’s important to understand that videos are different from images – a single video file can take up hundreds of MB (or even GB) of your web server storage space. The current global epoch is sometimes called the ‘information age’. The internet has made information and knowledge more accessible than it has ever been, and many commentators have written about how this is empowering ordinary people. It may be, however, that it is government and big business who are the most empowered – and at our expense. News summary of the monthly magazine, ‘Scientific India’.
