2. RAPID PROTOTYPING AND TOOLING
RP is an automatic process for manufacturing parts, prototypes, tools and even assemblies directly from their CAD models without the use of any cutters, tools or fixtures specific to the geometry of the object and without any human intervention anywhere in the process. A RP machine is a CNC machine with an embedded CAPP system for additive manufacturing. RP is also a “divide-and-conquer” manufacturing strategy in which a complex 3D manufacturing problem is converted into several 2D manufacturing problems which could be automated. The following are the benefits of RP:
● Rapid prototypes act as concept models for better visualization and communication.
● Marketing personnel can use rapid prototypes to assess the aesthetic appeal of the product by displaying them in showrooms.
● Rapid prototypes can be used for form, fit and functional tests.
●Transparent rapid prototypes obtained from photo-polymers are ideal specimens for stress analysis using photo-elasticity.
● Rapid prototypes can be used for wind tunnel tests.
●Assemblies can be made without joints using RP. It can make parts impossible by other manufacturing methods.
● Rapid prototypes can be sent along with the inquiries; RP models can be submitted along with the quotations.
● There are important medical applications of RP&T in conjunction with Reverse Engineering
● Rapid Tooling cuts down product ionizing time and hence sharpens the competitive edge of the organization.
● RP emerging into Rapid Manufacturing is possible in some applications.
● With an integrated approach, RP&T can shorten time to market.
Although RP&T could make the prototypes only out of proprietary non-metallic materials and the accuracy and surface finish are not adequate, direct and indirect methods are emerging to overcome these limitations. Hybrid technologies which exploit the best features of CNC and RP are also emerging. These efforts will shortly enable making objects rapidly from their CAD models automatically out of the required material with the specified quality.
The huge investments on such RP machines as well as the high cost of these prototypes can be amortized better if the same technology is able to produce tools through direct or indirect routes. It may be noted that processes like Selective Laser Sintering (SLS) and 3D Printing (3DP) are capable of producing prototypes from a wide variety of materials right from wax or polystyrene to metals. When the same technology can be extended for manufacturing parts in small batches, then it will be called Rapid Manufacturing (RM).
3. MICRO & NANOTECHNOLOGIES
The mission of the education center would be to foster a lifelong interest in Micro and Nanoscience and Technology.

5. MICRO & MINI AIR VEHICLES
MAVs can be utilized very effectively in:
● Disaster management ( Fire, floods, earthquakes, landslides, gas leaks, search and rescue)
● Defence / Security (Surveillance, Reconnaissance, communication relay, electronic warfare, mine/NBC detection, traffic control)
● Commercial (Agricultural, photography, television, cinema)
● R&D (Evaluation of new concepts)
The Concept of Micro Air Vehicles has gained increasing interest over the past few years, with the principal aim of the carrying out surveillance missions. In contrast to higher-level reconnaissance assets like satellites and high latitude UAVs, MICAVs will be operated by and for the individual soldier in the field as a platoon-level asset, providing local reconnaissance and acquire real-time visual information for a wide range of applications keeping personnel out of harm’s way by providing unprecedented situational awareness.
The Primary mission interest of MICAVs is surveillance and reconnaissance at battlefields and urban areas both day and night. These real time images provide vital information which is otherwise difficult to obtain. The advancement of sensor technology of smaller sizes has med possible missions like detection of targets of interests, biological agents, chemical compounds and nuclear materials. Envisioned civil operations are search and rescue operation in case of fire, earthquake and air sampling and gas detection – in places where it may not be possible to send humans for the job. Use of MICAV can also be very cost effective once the development unit is achieved.
6. QUANTUM WELL DEVICES
The project envisages the developmental of GaAs based Multijunction Quantum Well Infrared Photodetectors (QWIPS) using Metal Organic Chemical Vapor Deposition (MOCVD) technique. The work proposed in the present programme consists of the development of multi junction QWIPS. This project is designed for a period of 36 months, which consists of basic development and demonstration of a prototype device with a suitability of technology for the productionization. Quantum Well Infrared Photodetectors are based on NANO layers of GaAs and Al GaAs.
A QWIP element using 30 alternating nanolayers of Gallium Arsenide and Aluminum Gallium Arsenide has been fabricated successfully for the first time in India by the IISc-BEL group under the QWIP project imitated by NDRF. The good response obtained in the 3-5 micro windows was considered a major achievement by the monitoring committee which met on 26 August 2004.
Preparation and characterization of more elements are in progress to verify repeatability and fine turning of the QWIP structure.

12. STANDARDIZATION AND QUALITY
The National Design and Research Forum and the Institution of Engineers (India), Karnataka State Centre, organized a programme dedicated to “Standardization and Quality Assurance” on 14 December 2006 in collaboration with Bureau of Indian Standards and Association of Consulting Civil Engineers, India.
The programme was in two parts – first part comprised of “Lal C Verman Memorial Lecture” by Padmabhushan Dr Roddam Narasimha, Chairman, Engineering Mechanics Unit, Jawaharlal Nehru Centre for Advanced Scientific Research and the second part comprised of a half day Workshop on “The Role of Chartered Engineers in Strengthening the Revised Product Certification (ISI Mark) Schemes of BIS”.
Padmabhushan Dr Roddam Narasimha delivered a very thought provoking lecture on the theme of “Standardization” highlighting his experience in the field of aerospace structures. With specific field problems, he enumerated the importance of standardization and the fact why standardization should be flexible and should get updated as Science and Technology advances.
In the workshop which followed, the simplifications being contemplated by BIS for Product Certifications and the role of Chartered Engineers in the revised scheme were brought out, particularly by the BIS representatives. In the subsequent, interactive session, a few leading engineers from different disciplines came out with further suggestions for improvements in the proposed scheme. The programme was well attended by over 200 engineers from different disciplines.
