Abstract: 

1. Applications of Interfacing Nowadays, every complex manipulation of data is accomplished on a computer. A computer can handle extraordinary amounts of data. In the industry and in labwork, there is always a large amount of data to be handled and processes. The conventional way is to note the data from devices, such as the control and instrumentation panel, enter it manually in the computer and then process it. Computer interfacing has solved the problem of data acquisition. Now, the computer not only automatically acquires the data from the external hardware but is also programmed in a special way to send data to control the same devices. These devices are controlled to fulfil the machinery and production line needs.

 

Below are a few examples where computer interfacing can be used: 1. Monitor the speed of a motor and adjust it according to the requirements. 2. To monitor environmental parameters such as temperature and pressure and to keep these parameters constant or within tolerable limits. For example, cooling fans may be turned on when the temperature exceeds a certain value. 3. To turn on a machinery for a certain period of time. 4. In instrumentation, computers can replace oscilloscopes, multimeters and any measurement instrument imaginable.

Once we make an appropriate circuit and interface it with he computer, then each action is just a mouse click away.

Abstract: 

Introduction to Chaos: This introduction is a very elementary introduction to the science of chaos and gives a comprehensive, non-mathematical overview of the subject. This is an excellent starting point for the understanding of the principles of dynamical, deterministic, unpredictable systems. (Dr. Tariq Abdullah).

Science of Chaos: Video Presentation | Dr. Tariq Abdullah, our expert on chaos was there to field the questions from the viewers | 13 Oct 1999 | Children Library Complex, Lahore. This wide-screen presentation was primarily meant as a stimulant and interest-arouser. The duration of the movie was approximately 50 minutes. The fascination lay in a live display of many chaotic ensembles and interviews with the pioneers such as Mandelbrot, Lorenz, Bradley, Feiganbaum etc.

Abstract: 

The morphological properties of galaxies depend strongly on the star formation rates. One of the fundamental problems in astronomy is to determine the rates at which massive stars are forming in different types of galaxies in different environments. The spiral galaxies have been classified into three major categories based on the size of their bulge, the tightness of their spiral arms, and the resolution of individual star forming regions. These three types are Sa, Sb, and Sc galaxies. Earlier studies have suggested that star formation rates increase from Sa to Sc galaxies. We are conducting a large survey of Sa galaxies in order to determine various properties of these galaxies. Our preliminary results suggest that, contrary to the earlier results, star formation rates in these galaxies are comparable to the star formation rates in Sc galaxies. Furthermore, it seems that a significant fraction (15-20%) of these galaxies are going through a phase of interaction in the current epoch.

Lecture I: The Stellar Drama: The Birth, the Life and the Death of the Stars

How do stars evolve? Hubble Space Telescope has revolutionized stellar astronomy by capturing stunning images of stars about to be born to the remnants of massive stars that went supernovae. We will trace the history of stars from their birth to their ultimate, possibly catastrophic, demise.

Lecture II: A Tale of a Billion Galaxies

Once called the "island universes", galaxies represent a spectacle with beauty unparalleled in the universe. What are the factors that give rise to the different shapes of these galaxies? How do the nearby galaxies relate to the galaxies at the farthest reaches of space and time? Equipped with the Hubble Space Telescope, we will try to address these questions in the second part of the cosmic trilogy.

Lecture III: The Cosmic Saga: From the Big Bang to the Ultimate Fate of the Universe

How did it all start and how will it all end? Once purely in the domain of philosophy, cosmology - the study of the universe, is fast becoming an observational science. We shall look at the Big Bang Model of the universe in the light of current observations. We shall also discuss the role of dark matter and the ultimate fate of the universe.

Abstract: 

Integrated circuit industry has demonstrated phenomenal growth in transistor density and performance during the last three decades. Ever since the introduction of 1st SRAM, DRAM and microprocessor products (all fabricated by Intel Corporation ~1970), the number of transistors have roughly doubled every 2 years and microprocessor clock frequency has increased from less than 5 MHz to over 500 MHz. Moreover, this has been achieved by keeping the overall system power dissipation at acceptably low levels. These improvements have primarily been driven by improvements in process and device technology with feature size reducing to <0.25um (1/400th of thickness of human hair) on memory and microprocessor products currently available in the market. This talk will be divided into two parts. The first section will present the results from Intel's next generation microprocessor process technology generation. This technology demonstrates the highest transistor performance (i.e. highest drive current for a given off-state leakage) reported to date in literature. Moreover, this high performance has been demonstrated at ultra-low energies, with energy-delay product appreciably below the published industry trends. An SRAM product with more than 100 million transistors has been developed as a yield learning vehicle with frequency exceeding 1GHz. The 2nd part of the talk will focus on describing key bottlenecks which could limit further technology scaling during the next two decades. Alternate material options, which could delay the onset of some of the limitations, will be presented.
