Tunnel Boring Machine Technology: A review
In this modern era of “Construction Technology", the industry is parting with old techniques, researching for better alternatives and opting the state-of-the-art techniques for better and satisfactory output. In this review study, the various tunnel construction techniques have been discussed with special attention to TBM (Tunnel Boring Machine) technology. The study highlights the importance and practicability of modern TBM in contrast with traditional methods of tunnel boring/ underground excavations. Timeline of the technological advancements in TBMs have been discussed in detail. The study describes different types of TBMs, components, applicability in different geological conditions. The study explores, the history of TBM, its various types, excavation tools, muck management, tunneling works like tunnel lining, tail-skin seal and grouting, surveying and guidance systems, comparison of tunnel boring machine and conventional excavation techniques, various risks it is exposed to during transport, assembly, erection, testing, boring of a tunnel and disassembly. Apart from this, various challenges involved while working with TBMs have also been discussed and suitable corrective measures have been suggested. It has been observed that if the geological conditions are not identified or if known to be poor, construction workers need to carefully consider whether to use the TBM method or follow a more traditional approach. An optimal scheme should be suggested after analyzing geological conditions, construction progress, economic benefits and environmental impact. However, a number of tunnel boring machines are available with very high advancing speed and do not have many limitations. TBM technology has revolutionized underground space creation under the cities and allows easy construction of metro systems, water and sewage systems, and underground cable networks while maintaining safe and sustainable built environment. However, as different types of TBM are available, their suitability for different soil conditions revolves around the correct choice of TBM and the level of experience of the operator.

Temperature based fan speed controller
This project is a standalone automatic fan speed controller that controls the speed of an electric fan according to the temperature . It may also be used for monitoring changes in environment . The LM-35 Analog Temperature devices interfaced to analog pin of Arduino board, where it has built in ADC which convert these analog reading and displaying it on a LCD, which indicate the temperature of the device .This project is useful in process industries for maintenance and controlling of boilers temperature . This project is a self-contained automatic fan speed controller that regulates the speed of an electric fan to our specifications. This is closed due to the use of embedded technologies. The loop feedback control system is a highly effective and dependable system. A microcontroller (ATMega8 / 168 / 328) allows for dynamic and interactive control. Regulation is more rapid. The device is made possible by a liquid crystal display (LCD).pleasant to the consumer The fan and the temperature that was sensed

Water desalination using P-N sandwiched nanofluidic membranes
In this paper, a novel P-N sandwiched nanofluidic membranes, with two reservoirs connected to the P-N sandwiched nanofluidic membranes is simulated for near 100% multi-ions desalination to result clean water at fast transport of ~ 1 km/hr velocity that keeps the clean water supply going in a city. The P-N sandwiched nanofluidic membrane is electrically driven by Pt electrodes to drive the water and multi-ions similar to reverse electrodialysis (RED) method.

IoT based early flood detector and avoidance
Flooding may be a phenomenon which has attracted global attention as a results of its negative impact on the society. Developing nations like India are predicted to experience increased flood occurrences within the coming decade. The events of flooding are unlikely to vary , however, its impact on our society are often alright reduced. There are some places that are more susceptible to flooding than other places, the implementation of flood alert systems near any major water area or body of water provides critical information which will protect property and save lives.

Factors of Realism and Idealism in Indian Foreign Policy
Actors, Factors and Dynamics are the driving force of International Relations (IR). Ideologies often work as a beacon, shield or a guide for a nation while making of its foreign policy. Idealism and realism have been two most dominant ideologies of IR during 19th and 20th century. Both of them are continuously contesting to hegemonies each other since then. This research paper is an attempt to explain the continuity and explore the changes and examine the future implications of theory of idealism and realism on Indian foreign policy. The post independent Nehruvian Foreign Policy which was predominantly idealist with the pinch of realism in few instances like adopting mixed economic model and leadership of Non- Alignment Movement (NAM). The research work passes through Mrs. Indira Gandhi era, which was absolutely an era of realism in Indian foreign policy. Then Rajiv Gandhi government believed in a balance of both the ideas and maintained a status – quo. During 1990s despite of political turmoil foreign policy was guided with realism which opened Indian economy and doors of globalization. Economic considerations remained predominant factor to determine national interest. After 1998 the government under A. B. Vajpayee also followed realism as the guiding principal of foreign policy, which was continued by UPA government under Dr. Manmohan Singh till 2014. The change of regime in 2014 brought NDA government led by a strong and most popular leader Narendra Modi in power. He has made foreign policy and IR a vibrant policy area. Through his extensinve outreach to nations, leaders and people he left inedible footprints of realism in Indian foreign policy. This paper has looked into role of realism and idealism as a guiding principal in Indian foreign policy in its core (SAARC), periphery (Asia) and intruder (America, AU, EU, Latin America etc.) areas. It culminates with a possibility of extensive research in this area in future.
