Title: Multi-Agent Feature based Shape Grammar Implementation for Concept Generation of Industrial Product Design

Speaker: Dr Pritee Khanna, IIITDM Jabalpur

Venue: Conference room

Date and Time: 04-06-2010 and 4:30pm

Abstract: An agent based framework for the conceptual design generation stage of the Industrial product design process is proposed. The conceptual design is characterized by the multiple design generation and evaluation of the product concepts. The framework simulates the design team paradigm. Agent based architecture offers the advantage of being flexible, extendable and distributed. Added multiplicity of the shapes is achieved through the parametric variation and morphing of the feature elements. The implementation is demonstrated using a running example of a mobile phone, as it is simple enough to demonstrate the concept as well as complex enough to incorporate the team based paradigm of the design environment. The research is an effort to develop a design system to support the automatic concept generation and evaluation for the mass customization of industrial products.

Title: Development of Cutting Tool Condition Monitoring System

Speaker: Dr H Chelladurai, IIITDM Jabalpur

Venue: Conference room

Date and Time: 07-05-2010 and 4:30pm

Abstract: Cutting tool wear monitoring in machining operations has been an active area of research for nearly last two decades. Cutting tool wear plays an important role in deciding economic strategies, product quality, tooling cost, tool-changing cost, rejection of products and productivity. Metal cutting processes are in general non-linear and stochastic in nature. It is therefore difficult to represent them as a mathematical model and they usually require simplifying assumptions. As a result, these models are not capable to represent real world metal cutting process. For an automated industry, all the machining input parameters (cutting speed, feed rate, depth of cut) are controllable except cutting tool condition. Major problem in the machining process is cutting tool wear prediction. An attempt has been made to develop neural network models through sensor signals to predict the health of a cutting tool.

Title: Form Generation for Aesthetic Product Design

Speaker: Mr S Soni, PhD student with Prof. Tandon, IIITDM Jabalpur

Date and Time: 16-04-2010 (Friday) and 4:30pm

Venue: Conference room

Abstract: The CAD has proved to be a tool of choice for various phases of the product process, but the concept generation phase of the product design is poorly suopported by the current CAD systems. The reason for this misalignment is that the mathematical representation of surface design and manipulation is oblique to the way the designers think and interact with the design space.

The CAD tools have not been able to capture the designers intention efficiently. the reason being is that the porcess is poorly understood and context dependent. The CAD tools need a different paradigm to be adapted and integrated with the concept generation phase of the product design. The present talk discussed some of these issues and preliminary solution to achieve a more cohesive integration of the CAD and the product design process.

Title: Plasmonics and Nanoantennas

Speaker: Dr Dinesh Kumar V, IIITDM Jabalpur

Date and Time: 09-04-2010 (Friday) and 4:30pm

Venue: Conference room

Abstract:

Plasmonics: The development of chip-scale electronics and photonics has led to remarkable data processing and transport capabilities that permeate almost every facet of our lives. Plasmonics is an exciting new device technology that has recently emerged. It exploits the unique optical properties of metallic nanostructures to enable routing and manipulation of light at the nanoscale. A tremendous synergy can be attained by integrating plasmonic, electronic, and conventional dielectric photonic devices on the same chip and taking advantage of the strengths of each technology.

Nanoantennas: Antennas have been used to transmit and collect radio waves since the nineteenth century, radically changing our notion of communication in the process. The more recent challenge has been to apply these ideas to electromagnetic radiation at optical frequencies. It is believed that transplanting radio frequency (RF) antenna design methods and concepts into nanoantennas working at optical frequencies may lead to a technological breakthrough in terms of bandwidth, data rate and miniaturization, when compared with antennas in the RF domain.

Title: Superjunction Power MOSFET: Breaking the Silicon Limit

Speaker: Dr P N Kondekar, IIITDM Jabalpur

Date and Time: 26-03-2010 (Friday) and 4:30pm

Venue: Conference room

Abstract: The concept of "super-junction" in power MOS technology has been a major improvement over conventional power MOS transistors. The addition of a p strip in the drift layer creating a vertical p-n junction in drift layer will drastically change the electric filed distribution and becoming flat one instead of conventional triangular, this allows to enhance the breakdown voltage and at the same time reducing the on resistance, breaking the so called silicon limit BV \alpha R_on^2.5 almost becoming a linear relation. It has resulted in a significantly better trade off relationship between the on resistance and its breakdown voltage. Super-junction structures have been designed in this work using analytical formulas and have been extended to super-junction MOS transistors. By device simulations, the on resistance and breakdown voltage are investigated for various device parameters such as doping density, cell pitch, and the drift layer thickness.

Title: Modelling and Control of Mobile Robots

Speaker: Dr P K Padhy

Date and Time: 19-03-2010 and 4:30pm

Venue: Conference room

Abstract: In this work, a new approach for stable tracking of non-holonomic wheeled mobile robot using PID controller is proposed. The major objective is to propose a control rule to find out reasonable target linear and rotational velocities of the mobile robot. The method requires the information about the position (Cartesian space and orientation) of the mobile robot only which can be obtained by any kind of positioning system. In the approach, the mobile robot, including the actuator dynamics is identified by a linear model using recursive least square method. The identified model is then used to design the PID controller to set the target linear and rotational velocities for smooth path tracking.

Title: Electromagnetic analysis and solvers

Speaker: Mr Biswajeet Mukherjee, IIITDM Jabalpur

Date and Time: 12-03-2010 (Friday) and 4:30pm.

Abstract: Computer -aided Design of passive RF and microwave components has advanced slowly but steadily over the past four decades. However, in the past decade the rising demand for highly integrated transceivers for wireless, RF and optical applications, low cost radio frequency integrated circuits (RFICs) and Multi-Gigahertz processors has generated tremendous requirement for efficient and accurate modeling of on-chip and off-chip passive components and interconnects. In system integration, the impact of packaging and signal integrity issues are other aspects that need attention to achieve proven designs/goals. Electromagnetic (EM) solvers are considered as the best tools for such analysis in RF and high speed designs and are equally important in Parasitic Extraction space.

Parasitics include interconnect parasitics as well as coupling among passive devices, interconnects themselves and ground planes. Furthermore, the layout density and GHz range operating frequency introduces numerous high frequency effects including time retardation, the skin effect, substrate effects and frequency resonances. It is essential to accurately predict parasitics and the numerous high frequency effects while designing RF circuits.

Various electromagnetic solvers are available in the current market to analyze, two dimensional (2D), two and a half dimensional (2.5D) and three dimensional (3D) structures. There is always a trade-off between the accuracy and efficiency of these solvers. Designers as well as tool developers require the knowledge of different solving algorithms, methods and the applications of 2D to 3D solvers in the design to make an exact trade-off for efficient and accurate modeling.

Title: Energy Harvesting

Speaker: Dr V K Gupta

Venue: Conference Room

Time and Date: 4:30pm and 05-03-2010 (Friday)

Abstract: Today's world is looking for alternate sources of energy. Energy is required both at macro and micro level. At micro level batteries have been the source of energy. Now, with ubiquitous computing requirements in the fields of embedded systems, wireless sensor networks and low-power electronics such as MEMS devices, an alternative source of energy is required. Also with the limited capacity of finite power sources and the need for supplying energy for a lifetime of a system, there is a requirement for self-powered devices. The process of extracting energy from the surrounding environment is termed as energy harvesting. There are various forms of energy that can be scavenged, like thermal, mechanical, solar, acoustic, wind, and wave. In this talk some of the issues related to energy harvesting are addressed.
