Dr. Peter Magyar (IEEE M'91, SM'04, F'07) received the Dipl. eng. and the Dr. tech. degrees from the Budapest University of Technology, Hungary, in 1967 and 1975, respectively. From 1967 to 1991, he was with the Department of Automation of the same university as an assistant professor and a research associate. From 1982, he led the Laboratory of Microprocessor Controlled Drives of the same department...
With recent advances in Internet and multimedia technology, the involvement of digital images in sexual offenses against women and children has been increasing significantly. These sexual offenses can be rapes, child sexual abuses and gang rapes. Even in one child sexual abuse case, evidence images and videos can be over 100 gigabytes. In Canada alone, Cybertip.ca received over 21,000 tips about online...
This paper presents a parametric sweep analysis discussion on proposed DC-DC boost converter circuit for low and wide voltage supply range. Analysis is initially done using computer simulation and then tested with experimental work. Results are combined and discussed in details. In this work, effect of parameter such as input voltage, switching frequency and inductance is presented in details. A linear...
Social media offers a wealth of insight into how significant events? such as the Great East Japan Earthquake, and the Nepal Earthquake affect individuals. The scale of available data, however, can be intimidating: during the Great East Japan Earthquake, over 8 million tweets were sent each day from Japan alone. Conventional word vector-based event-detection techniques for social media that use Latent...
Understanding modern data communication networks such as the Internet involves collection and analysis of data collected from deployed networks. It also calls for development of various tools for analysis of such datasets. Collected traffic data are used for characterization and modeling of network traffic, analysis of Internet topologies, and prediction of network anomalies. In this talk, I will...
Conventional PI controller has overshoot effect at the transient period of the speed response curve. Most of the controllers of Induction Motor (IM) for industrial applications have been designed based on PI controller without consideration of core loss (CL) and stray load loss (SLL). In order to obtain the precise performance of torque as well as speed and flux, the mentioned losses should be considered...
Bangladesh is agriculture based country and optimization of this sector is being hampered due to lack of electricity and high prices of diesel fuel. An alternative option to overcome this crisis would be a solar based irrigation system which is a clean and environment friendly energy. A solar irrigation system of capacity 3KW has been installed in a remote location near Mymensingh which is about 120km...
Compressed Sensing or Compressive Sampling is the process of signal reconstruction from the samples obtained at a rate far below the Nyquist rate. In this work, Differential Pulse Coded Modulation (DPCM) is coupled with Block Based Compressed Sensing (CS) reconstruction with Robbins Monro (RM) approach. RM is a parametric iterative CS reconstruction technique. In this work extensive simulation is...
QCA (Quantum-dot Cellular Automata) is the most capable future nanotechnology for computing. Defects are most likely to occur in QCA devices due to the nanoscale Faults caused by these defects must be analyzed. This paper implement the QCA combinational circuit, half adder for which fault analysis is carried out. This paper presents the fault analysis of QCA combinational circuit, half adder at layout...
Phased array antenna can produce beam with high directivity at any direction without any physical movement of the antenna array. The main drawback of this antenna is high side lobe level and grating lobe at different scanning angles that creates severe interference to proper communication. In order to mitigate such problem in array design, optimization is applied for thinning of phased array at different...
In this age of miniaturization and nanotechnology, nano sized zero dimensional particles called quantum dots are finding wide range applications. The reasons behind their growing popularity are their controllable electrical and optical properties. This control is achieved by tuning their bandgaps by changing their shape and size. But quantum effects are most prominent only within strong confinement...
About 65 million people out of 650 million with disabilities in the world require wheelchairs for mobility. Only a minority of them have access to electric wheelchairs in developing and underdeveloped nations. The count is even less when it comes to sophisticated wheelchairs. These electric wheelchairs come with joystick control which is not suitable for people with stroke and spinal cord injury....
