  • The field of industrial electronics covers a plethora of problems that must be solved in industrial practice. Electronic systems control many processes that begin with the control of relatively simple devices like electric motors, through more complicated devices such as robots, to the control of entire fabrication processes. An industrial electronics engineer deals with many physical phenomena as well as the sensors that are used to measure them.

  • The research in this paper seeks ways for manufacturing companies to accomplish projects in real time with less cost. This paper describes a new model using critical success factors of implementing projects in small- and medium-sized enterprises (SMEs). The factors in the conceptual model were identified in past studies and are validated from interviews with 20 project managers in the electronics industry in Iran. Several prior researches have suggested critical success factors for reducing time and cost in the development of a new product. These factors are...

  • The ultrasonic transducer behaves as a ‘speaker’ in send mode (from 40 to 50 kHz). The electronics of the ultrasonic transducer produces electrical pulses to set the piezoceramic element in motion (conversion of electrical energy to mechanical energy). The piezoceramic element is located on the inside of the outer diaphragm. The outer diaphragm vibrates in line with the resonance frequency and produces ultrasonic waves. The short pulse sequences hit an obstacle and are bounced back (reflected).

  • In a time when digital electronics is becoming more complex and less accessible to students and low-end project and product developers, microcontrollers have become the tools of choice for learning about electronics and programming as well as providing the capabilities needed to create sophisticated applications cheaply and easily. If you were to look through any electronics magazine, you would discover that almost every example application uses a microcontroller (often abbreviated to just MCU) to provide a user interface, sequence operations, and respond to changing inputs.

  • The World is confronted with a plethora of potentially disruptive technologies – some, such as nanotechnology, will inevitably challenge our cherished social, economic and industrial stability over the next two decades. Rational design and manufacture of materials properties through nanostructure control will profoundly affect the food we eat, the sources of water and power we use, our health services, our national security, housing, transportation, etc. Precisely what will be the ultimate effect of these disruptions is still unclear.

  • The subsequent survey in the second demonstration, regarding the use of electronic music in a screening of Haxan: Witchcraft Through the Ages, yielded similar results. The survey found that 78.1 percent of the new group saw the elec- tronic music as enhancing their engagement with the film. A further 18.7 percent found that the music detracted, while only 3.1 percent remained neutral. In con- trast, only 50 percent of these students would have found a piano or organ score beneficial, while only 46.8 percent would have benefited from a symphonic score....

  • We study how the trapping time of an electron in a circular graphene quantum dot depends on the electron’s angular momentum and on the parameters of the external Gaussian potential used to induce the dot. The trapping times are calculated through a numerical determination of the quasi-bound states of electron from the two-dimensional Dirac-Weyl equation. It is shown that on increasing the angular momentum, not only the trapping time decreases but also the trend of how the trapping time depends on the effective radius of the dot changes.
