The National Frontiers of Engineering Symposium was launched by the INAE in 2006 as one of its annual flagship events. It brings together young and outstanding engineering professionals (aged ~30-45 years) from industry, universities, and research organizations to deliberate upon emerging and leading-edge research and development work in the domain of engineering and technology. Convening engineering professionals and technologists from various fields and providing a platform for braintorming the contemporary and futuristic issues related to frontiers areas translational research and innovation. The desired mode of interaction may include collaborative work, complementary development of new techniques and approaches, and establishment of contacts among the next generation of leaders in engineering. The format of the symposia encourages both formal and informal discussion in groups as well as one-on-oneformat. Speakers may be advised to focus their talks on current cutting-edge research in their respective disciplines to colleagues outside their field and to address questions such as: What are the major research problems and distinctive tools used? What are the current limitations in advancing and possible ways to overcome these limitations?
The 12th National Frontiers of Engineering (12NatFoE) Symposium was held for 2 days (17-18 September 2018) conducted through evenings. There are three segments to the Symposium.
Since Newton’s discovery of composite nature of white light in 1664, remote sensing in all ranges of wavelength has been used to study the properties of terrestrial/ extra-terrestrial surface and environment. Conventional techniques of surface/ sub-surface investigation involve detailed field mapping, sampling and extensive chemical and mineralogical analyses. However, remote sensing techniques offer quick, non-destructive, up-to-date and accurate information from spaceborne/airborne sensors. In earth science, remote sensing has been widely used for lithological mapping, structural interpretation and to aid in prospecting for ores and hydrocarbons. In addition, remote sensing has been proven an important source of information in developing a decision support system for susceptibility, preparedness and mitigation during the event of a natural disaster.

Cyber security is an essential requirement in the digital world. How well secured are one's personal data on the Internet is the most pressing question by users today. Cyber security is responsible for protection of data on the Internet from attack, damage, misuse, and economic espionage. India ranks third in terms of the number of Internet users in the world and this number is expected to increase manifold by the year 2020. It is expected that by the year 2020, the number of online shoppers, e-commerce transactions, and travel transactions will increase exponentially along with the inclusion of a large number of new rural users. With such increase of users, the number of cyber crimes is also increasing dramatically. Hence, it is becoming necessary to provide solutions for protection of users' data from its inherent vulnerabilities over the Internet.

Additive Manufacturing (AM) is used for manufcturing three dimensional parts with the help of computer technology by adding
layer-upon-layer of material. Different parts were made from plotymer, melattic, material with soft robots, flexible materual,
ceramis, and concrete etc. AM technique can be used to develope very complex parts which is difficult through conventional
manufacturing processes. As per ASTM standard, AM techniques are classified in seven groups as
→ Stereo-lithography (SL)
→ Stereo-lithography (SL)
→ Powder Bed Fusion (PBF)
→ Material extrusion (Fused deposition modelling FDM)
→ Material jetting (MJ) 3-D Printing
→ Binder Jetting (BJ) 3-D Printing
→ Selective Laser Sintering (SLS) or SLM (selective laser melting )
→ Directed energy deposition (DED)
During the session, basic idea of additive manufacturing is explanied and detailed information about selective laser melting (SLM ) and FDM type additive manufacturing with industrial robotics technology is presented. Digitial file writing or coding for additive manaufcaturing required is also discussed. Application of 3-D Printing in medical device development with example are presented.
Very high end technology utilizing laser technology to cure layer-upon-layer of photopolymer resin (polymer that changes properties when exposed to light). The build occurs in a pool of resin. A laser beam, directed into the pool of resin, traces the cross-section pattern of the model for that particular layer and cures it. During the build cycle, the platform on which the build is repositioned, lowering by a single layer thickness. The process repeats until the build or model is completed and fascinating to watch. Specialized material may be needed to add support to some model features. Models can be machined and used as patterns for injection molding, thermoforming or other casting processes.
Process oriented involving use of thermoplastic (polymer that changes to a liquid upon the application of heat and solidifies to a solid when cooled) materials injected through indexing nozzles onto a platform. The nozzles trace the cross-section pattern for each particular layer with the thermoplastic material hardening prior to the application of the next layer. The process repeats until the build or model is completed and fascinating to watch. Specialized material may be need to add support to some model features. Similar to SLA, the models can be machined or used as patterns. Very easy-to-use and cool.
Multi-Jet Modeling is similar to an inkjet printer in that a head, capable of shuttling back and forth (3 dimensions-x, y, z)) incorporates hundreds of small jets to apply a layer of thermopolymer material, layer-by-layer.
This involves building a model in a container filled with powder of either starch or plaster based material. An inkjet printer head shuttles applies a small amount of binder to form a layer. Upon application of the binder, a new layer of powder is sweeped over the prior layer with the application of more binder. The process repeats until the model is complete. As the model is supported by loose powder there is no need for support. Additionally, this is the only process that builds in colors.
Somewhat like SLA technology Selective Laser Sintering (SLS) utilizes a high powered laser to fuse small particles of plastic, metal, ceramic or glass. During the build cycle, the platform on which the build is repositioned, lowering by a single layer thickness. The process repeats until the build or model is completed. Unlike SLA technology, support material is not needed as the build is supported by unsintered material.
Increasingly, interdisciplinary engineering skills, clinical knowledge and practical perspective are required to solve healthcare challenges. To support diagnosis and therapy, it is necessary to research and develop both the theoretical potential of clinical data and wearable medical devices. Clinical decision support systems help physicians make sense of clinical big datasets obtained from patients. These systems would analyze and provide physicians with meaningful reports so that appropriate therapies can be implemented. Another requirement in today’s fast paced world is the requirement of self-health monitoring, mobility and preventive medicine. Wearable medical instrumentation can enable this by reducing monitoring cost, providing reliable biomarkers and tools for long-term health monitoring.
