Naguib Mahfouz and the 21st Century
After the Nobel laureate survived the attempted assassination on him in November 14th, 1994, Mahfouz couldn’t write for about 3 months and even after rehab he couldn’t write for more than 30 minutes a day, all because of the assassin stabbing him in the neck which damaged the nerves of his right hand, his writing hand, which had an important role in delivering all of his great novels, short stories and articles, specially his weekly column in al-Ahram newspaper. But as a great writer, to be forced to work for only half an hour each day is just torture, and as a result he had to rearrange his priorities, so he kept it for his literary writings, and turned his weekly column into an interview with Mohamed Salmawy in which Salmawy would bring up a subject and see what Mahfouz had in mind about ...
Analog vs. Digital
In a world full of Analog signals and waves, some engineers got mad and decided to transcend to a more certain level of true and false, or in digital terms, 1 and 0. Sound, temperature, light intensity, power and most of the natural phenomena we interact with on daily basis can all be represented by analog signals, or to be more specific, have a continuous curve relation between its dependent and independent variables. But what if we decided to draw a line? Between what we consider is acceptable and not acceptable? A barrier that separates what we can work with and what we can’t accept at all? Now that is digital. If we were to construct a circuit consisting of a sensor, a deciding mind and an acting hand to measure the room temperature and to turn on the AC if the temperature dropp ...
The Embedded Systems Series – Part 2
In part 1, we had a brief insight about embedded systems and tackled some misconceptions about it. In this article we will considered the career options for embedded engineers and have a study case of cell phones as an example for an embedded system. 2.Careers in Embedded Systems As you may have recognized that we can’t consider embedded engineers as hardware-only guys or software-only guys, but they must comprise a skill set of both levels even if they are specialised in one of these levels in their embedded careers. Most embedded engineers are graduates of EE or CS department, so if you rely on what you study in college only, you might end up with only half what is required to be a good embedded engineer. Embedded Engineers write software that controls the VLSI chips. Embed ...
Adaptive Traffic Signals Control
“When it feels; it deals.” One day, I was on my way to a very important interview. I left home very early to arrive on time. I was wondering, when the traffic will be smooth and stop wasting our time! When I arrived home, I started to search for a solution. Luckily, I found a scientific solution that civil engineers applied in America. This solution is called “Actuated Traffic Signals Control”. The idea simply is: Each intersection contains detectors, which record the traffic volume and send a signal to the controller with the actual information. The controller changes the phase lengths to correspond to this signal without affecting on other intersections. This system depends on historical data in designing the phase lengths. This system is divided into two ...
Success Begins at Sixty: A Biography of the Founder of KFC
Best known for founding the fast-food chain Kentucky Fried Chicken, Colonel Harland David Sandars was born in 1890, in Indiana State in the United States.
