Venue: 
Electrical Engineering Department, University of Engineering and Technology (UET), Lahore
Abstract: 

Nanotechnology, the ability to work at the atomic and molecular level, atom by atom to create materials and structures with new capabilities, will fundamentally change electronics, computers, medicine, biotechnology, and many other industries. The current research in this area is meant to explore the science of nanostructures and new materials, to develop the enabling technology for producing new classes of electronic and biological devices, and to educate the scientists and engineers who will carry this vision forward. This talk is about the prospects of Nanotechnology and the challenges in this emerging field. It is targeted to undergraduate students in Physics, Chemistry, Electrical and Mechanical Engineering. The complexity of the topic would be minimal and its level would be elementary. It would span discussion on Carbon Nanotubes, Molecular Electronics, Nano-Electromechanical Systems, Ultrathin (1.7-7nm) oxides and nitrided oxides for CMOS applications and Noise Spectroscopy.

Abstract: 

UAV's, as the name suggests, are flying vehicles without an onboard human personnel, they are either remote controlled or onboard computer guided. These are one of the most advanced weapons being used during many modern wars and peacekeeping missions. They belong to the category of unconventional warfare. By effectively employing them one may achieve strategic victory without putting human lives to risk, so they may be regarded as peaceful weapons. It is one of the areas of active research in our country which include both the equipment development as well as the software development. In the equipment development they are usually made from Aramid and Carbon fiber based epoxy matrix composites and in software development they employ high end Artificial Intelligence, Neural Networks, Image Processing, etc. So both fields require highly qualified experts. In this small session we will attempt to shed some light on the basic aspects of this smart weapon and will try to study some of the models currently developed and used in the defense industry internationally.

Quantum Computing

Making Atoms Think
Registration: 
Open to all.
Date: 
26 April, 2001
Time: 
11:00 am
Venue: 
M.Sc. Seminar Room, Electrical Engineering Department, University of Engineering and Technology (UET), Lahore
Abstract: 

The fundamental limits of silicon computing motivated the idea of quantum computing several years ago. Although technological feats have not yet been established in the arena, promise of using quantum mechanical principles, flowing naturally from a consistent attempt to understand nature, is both assuring and satisfying. This seminar will discuss how quantum omputing is different from classical computing. It will make use of a simple quantum algorithm to show the inherent superiority of quantum techniques over their classical counterparts. This will be followed by an outline of some exciting areas in quantum information theory: namely entanglement and non-locality and will show how teleportation works. Finally, some plausible physical implementations of quantum computers will be sketched. The scope of the presentation will be elementary, and mathematics will be kept to a minimum.

Microelectronics

From Transistor to Single Electron Devices
Registration: 
Open to all.
Date:

Venue: 
Electrical Engineering Department, University of Engineering and Technology (UET), Lahore
Abstract: 

Electronic devices have seen tremendous improvement since the discovery of electron. A brief history of the progress in microelectronics industry will be presented with emphasis on memory devices and information technology (IT). The limiting factors in the future progress will be discussed, and need for new concepts and devices will be established. Results of memories and logic circuits based on silicon nano-wires as single electron tunneling transistors (SETTs) will also be presented. Microelectronics research at Cavendish laboratory has resulted in a new device named PLEDM. Results are presented with the courtesy of Prof. H. Ahmed. This is shown to be a replacement of DRAM, which is currently the single largest selling electronic component. A new dimension of future microelectronics research will also be discussed.

Seven Ideas that Shook the Universe

Registration: 
Open to all.
Date:

Time: 
11:00 am
Venue: 
New Lecture Theater, University of Engineering and Technology (UET), Lahore
Abstract: 

The book "Seven Ideas that Shook the Universe" covers the development in the field of physics in a very comprehensive way. The authors have divided these developments into seven periods which are termed as the seven ideas. The author have employed a descriptive approach rather than mathematical expressions. The first idea is the "Copernician Astronomy" which covers the early developments of classical physics especially astrophysics. The second idea is the "Newtonian Physics" which covers the contributions made by Sir Isaac Newton and other scientists of his time in classical physics. Next comes "the concept of heat" which covers early developments in Thermodynamics. "Entropy" is the next topic which also covers the thermodynamics. Next is "quantum mechanics" which was our fist approach towards modern physics. The sixth idea is the "theory of relativity" which covers the special and general theories of relativity as presented by Albert Einstein. This theory revolutionized the field of physics and laid foundation stones of modern physics. The seventh and the last topic is the "Symmetry and other Modern concepts" which covers the recent advancements in modern physics including field theory, conservation laws, symmetry, virtual quantas, fundamental atomic particles and Quark Model. The authors of the book give a very comprehensive review of the developments in physics in a story like manner.

Magnetic Resonance

From Brain Tissue to Chloroform Computers
Registration: 
Open to all.
Date: 
12 April 2000
Time: 
11:00 am
Venue: 
Electrical Engineering Department, University of Engineering and Technology (UET), Lahore
Abstract: 

Nuclear magnetic resonance is a technique that exploits the inherent spin of sub-atomic particles inside the nucleus to obtain a tell-tale signature of the nucleus. This technique finds immense use in diagnostic imaging of human tissue. This presentation will be a simple approach to the physics of the phenomenon of magnetic resonance and will also touch upon the technological aspects of the imaging mechanism. Moreover, starting from its medical applications, this talk will also address other novel and esoteric applications, especially its application to quantum computers.
