(2010-08-25)
Today, nanotechnology has added a new dimension to materials technology by creating opportunities to significantly enhance the properties of existing conventional materials. Polymer nanocomposites belong to one such class ...
Integrated Approach To Filter Design For Grid Connected Power Converters
(2010-12-30)
Design of filters used in grid-connected inverter applications involves multiple constraints. The filter requirements are driven by tight filtering tolerances of standards such as IEEE 519-1992–IEEE Recommended Practices ...
Comparative Evaluation Of Space Vector Based Pulse Width Modulation Techniques In Terms Of Harmonic Distortion And Switching Loss
(2010-09-14)
Voltage source inverters (VSI) are popular in variable speed induction motor drive applications. Pulse width modulation (PWM) is employed to achieve variable voltage variable frequency output from a fixed DC bus voltage. ...
Modeling Of Dust Loaded Electrical Characteristics And Collection Efficiency Of Industrial Electrostatic Precipitators
(2010-12-08)
With the increase in population and industrial growth, the need for power has increased manifold. A major share of India’s power generation is coal-based generation. Thermal power generation through coal combustion produces ...
Bidirectional Invertor With High Frequency Ac Link
(2010-09-22)
It is customary to obtain ac power from batteries through a power converter, where mains ac power is not readily available. Such a power converter is also needed in several mobile/ airborne/ space applications.

Transient Lightning Electromagnetic Field Coupling With An Airborne Vehicle In The Presence Of Its Conducting Exhaust Plume
(2010-09-03)
The indirect effects of a nearby lightning strike on an airborne vehicle with its long trailing conducting plume is not well understood. Since airborne vehicles and its payload are expensive, their loss as a result of ...
Truncated Data Problems In Helical Cone-Beam Tomography
(2010-07-19)
This report delves into two of the major truncated data problems in helical cone-beam tomography: Axial truncation and Lateral truncation. The problem of axial truncation, also classically known as the Long Object problem, ...
Straegies For Rapid MR Imaging
(2010-07-21)
In MR imaging, techniques for acquisition of reduced data (Rapid MR imaging) are being explored to obtain high-quality images to satisfy the conflicting requirements of simultaneous high spatial and temporal resolution, ...
An Algorithmic Approach To Some Matrix Equivalence Problems
(2010-06-09)
The analysis of similarity of matrices over fields, as well as integral domains which are not fields, is a classical problem in Linear Algebra and has received considerable attention. A related problem is that of simultaneous ...
Experiential Sampling For Object Detection In Video
(2010-08-26)
The problem of object detection deals with determining whether an instance of a given class of object is present or not. There are robust, supervised learning based algorithms available for object detection in an image. ...
