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

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

I write on a variety of topics on the Maven Coalition network of sites (Owlcation, DenGarden, TurboFuture, ToughNickel, SkyAboveUs and others). Let’s look at the example of communication as it has definitely changed the way of our daily life. Many years ago we used to communicate via writing but now we communicate by using information network like telephone, mobile phone, internet etc. The application IT has changed considerably as we can now communicate via text message, email and communicating via instant messaging on MSN messenger, Facebook and even in the form of Tweets on Twitter. So, it has significantly changed the world’s communication over time. Macs are well endowed with included software and utilities: from the very useful Preview utility that offers a quick peek at just about any file type, to the included office and media apps. You also get Apple Maps, Podcasts, Mail, Calendar, Notes, Reminders, and we … Read the rest
