What is nanotechnology?
Nanotechnology is a multidisciplinary branch on engineering involving study of materials at a length scale of 1-100 nm. One nanometer is a billionth of nanometer. For reference, a sheet of paper is 100 thousand times thicker than a nm and a human hair is 70 thousand times thicker than a nm. Nanotechnology involves synthesis, imaging, modeling, and manipulating materials at this length scale. The materials properties at this length scale are very different than the bulk scale properties of materials. The difference between bulk properties and nanoscale properties is due to the different nature of physics theories. At nanoscale the quantum effects govern the properties of the materials unlike at the bulk scale where classical mechanics govern the behavior of material properties. Because of this difference, the materials designed using nanotechnology demonstrate unprecedented properties and scientist are taking advantage of nanoscale phenomena to bring useful and innovative applications.
Carbon nanotubes are one of the most researched nanomaterials because of their excellent mechanical, electrical and thermal properties. It consists of carbon atoms covalently bonded in a cylindrical crystalline lattice. A single wall carbon nanotube consists one cylinder of carbon atoms while multiwall carbon nanotubes have many concentric cylindrical lattices of carbon atoms. Single walled carbon nanotubes (SWCNTs) are much lighter yet many times stronger than steel making them the strongest known material. The Young’s modulus of SWCNTs is in order of 1 TPa, where as carbon fibers have 800 GPa and glass fibers have 70 GPa. CNTs have average breaking strength of 30 GPA whereas carbon fiber about 6 GPa and high strength steel about 3 GPa. Continue reading

As electricity demands are increasing day by day causing unbalance in the present grid system which results in various causes like load shedding, unbalance voltage etc. which ultimately affects the consumers.
Though government has taken series of steps to increase the generation capacity, it has lagged behind electricity demand and in addition to this, almost 25 -30% generated power is lost due to theft and other technical and non-technical factors. The major part of this loss occurred in the distribution sector, which is most daunting sector due to its complexity, interface with public at large with different needs & expectations. These high losses are neutralizing all other efficiency and improvement initiatives, which are the biggest challenges for distribution sector. The need to improve this sector was realized and step had taken to reduce high transmission & distribution (T&D) losses, control the theft / pilferage and rationalize the tariff.
The adaptation of smart grid offers a potential to revolutionize electricity supply system more effectively. Smart grid is a platform that integrates, monitor and operate electrical system in an automated fashion and provides a better use of existing network with basic automation systems followed by its upgradation. In India, challenges for implementation of smart grid are high transmission & distribution (T&D) losses, power theft, inadequate grid infrastructure, low metering efficiency and lack of awareness. The adoption of smart grid in India is a necessity not a luxury and will have following priorities. Continue reading

Summary: Ethics and professional values are the most precious for professionals such as Engineers, Doctors, Lawyers, and Tax consultants. Since civilizations, India has been recognized for high ethical, professional and human values. However, after arrival of foreign rulers as well neo-rulers post-independence, there has been sharp decline and degradation in ethical and professional standards among Indian youths. The important reasons for degradation of ethical standards may be attributed to values in the university such as privatization of higher education system, delay in reinforcement of minimum technical education standards, easy access to large pool of information available through internet; values in the community such as excess exposure to social and digital media resources, declining human values among family and youths, limited mentoring support from family, and values in the world community such as over dependence on material wealth. The situation got further compounded as values in the world community got extremely high social recognition, and thus excessive increasing the market demand of professions such as engineers, doctors, managers, and lawyers. This article explores new possibilities and means for high professional values for technical education in India. The author suggests several possibilities to recover lost glory of Indian civilization, and establish once again modern Bharat based on high standards in human values and ethics, simplicity of living, and freedom of professional expression.
The Technical education landscape is changing rapidly due to establishment of large number of private universities and academic institutions in India during last 10-years. Indian higher education system needs massive expansion up to 1500 universities during next 5 years, in order to attain a gross enrolment ratio of 15% of the population, as desired by Government of India. In spite of last 6-decades of sustained efforts, India has just 160 central universities, 320 state universities, 210 private universities, and 12,800 technical institutions. The academic quality of these universities and institutions varies due to poor compliance of academic standards as laid down by regulatory agencies. Just one-third of universities and one-fifth of technical institutions in India have been accredited either by National Academic and Accreditation Council (NAAC) or National Board of Accreditation (NBA).

As computer networking becomes an increasingly routine part of our daily lives, the jobs of computer networking specialists and administrators become more important. It is the job of the computer-networking specialist to keep the networks working. Once a network goes down, many businesses cease to function until it returns to normal. Computer networks have become the communications backbone of large and small businesses.
Networking is changing the world of consumer electronics, biomedicine, industrial automation, supercomputing, cloud computing and defence. With the advent of Ethernet-enabled sensors and controllers, companies are increasingly looking at hooking their factory floor to their executive offices and beyond. Enterprise management is another widespread application made possible by networking. Continue reading
Technology is changing at fast pace and is finding its place in daily lives, be it using GPS to reach destination, searching of a recipe, uploading your experiences of a tour, watching a movie, sharing photograph or viewing and trusting other’s experiences whom you do not know before buying a product. Education is also not untouched. Blended learning includes combining face-to-face instruction deliveries with computer-mediated teaching and learning. Question arises to what extent Technology can support engineering education in today’s scenario. Gone are the days when usage of technology in education meant usages of slides with bulleted points typed in them.
There are varieties of ways to embrace it in education. Avenues of collaborations are opened up at a wide scale with the advent of technologies. With technology, faculties and students have a variety of learning tools at their smart tops, be it laptop or smart phones. Abundant credible literature is available online in video as well as text format that can be utilized by both teachers and students. Faculties along with delivering content face to face also apprises of students about relevant resources on internet, video lectures of distinguished faculties and eminent scientists. In best universities in Jaipur, Quality presentations prepared by faculties with appropriate animations can make their job easier in explaining concepts. Learning Management Systems facilitates topic wise uploading of Lecture Materials, Detailed Tutorials, Practice Exercises and Supplements to understand the topic. Students after attending face-to-face class can browse the content multiple times at own pace and need. Students can also submit solutions to assignments online, where in faculties can keep track of dates of submission, put their comments and also demand revised submission, maintaining the track of revisions of assignment.

Are we living in a “Connected World”? Yes, to some extent! One should not wonder after hearing such conversations. The technological advancements in recent times has made it possible that in today’s world wherever we go, whatever we do…we are connected! How has it become possible? With the advancement in the design and development of Information Technology (IT) content, Internet Protocol, Computing Hardware, Communication Devices (wired / wireless) etc. it has become possible to remain connected to our near and dear ones either being at home, in an office, in a supermarket, while traveling etc. Of course there is much to be done! The technology has become an integral part of our day-to-day life without which we would feel isolated. Recent progress in the Internet-of-Things (IoT) technology, whereby one can control certain devices even from remote locations could make our lives even more comfortable and improve the quality of life. But, there are numerous challenges associated with the companies operating in these sectors in terms of recruiting quality manpower (researchers, scientists, application developers, skilled technicians etc.).
Even though some declining trend has been noticed in the Information Technology sector (IT party is over. Now’s the time to reinvent or die, by Ravi Venkatesan, 31st May, Sunday Times, Times of India) a bright future looks still ahead for those who are mobile and web application developers, data scientists and engineers and not to be forgotten the cyber security experts. Furthermore, in the context of India, the Government of India’s (GOI) flagship program like “Digital India Project” would create over five crore jobs according to the Telecom Minister Ravishankar Prasad (12th June, 2015 address to students at Shri Ram College of Commerce, New Delhi). This indicates that we need to create manpower in the above mentioned areas to meet the challenges of future. Continue reading
What makes Engineering Institute as ‘Best Engineering Institute’? Is it only excellent placement data or only passing percentage of Engineering graduates? In previous years, most of the Engineering aspirants used to judge the Engineering Institute based on its placement history. Now days, the focus is shifted from placements to sustainable placements or recruiters’ feedback. In this way, alumni are playing a very important role at this stage. The question arise that Why? and How? Alumni are the brand ambassadors of any educational Institute and if excellent feedback by corporate world creates a sustainable industry interface with such Institution. Those successful alumni also share very positive feedback of an Institute. Alumni performance at the company is affected by several factors in which the major factor is the skills that they had adapted during their studies.
As per an article published in Business Today recently and as per reports published in various newspapers reveal that only about 30 per cent graduates in India are job worthy. In case of Engineering graduates it is reported that their employability worth lies somewhere between 20 to 25 per cent. Many academicians feel it could be still lower. It is therefore important to dwell upon the possible reasons which cause low employability of Indian graduates in general and Engineering graduates in particular. The international ranking of higher education Institutions in India and their failure to enter the list of top 200 Institutions of the world, and the low employability of Indian graduates has started all across the country. This is due to the theoretical nature of course curriculum at B. Tech level. The Institutes claims about most updated curricula, excellent laboratories, etc. but as per the reports, the focus on providing quality education is lost and the need has been realized to look into this issue seriously.
Higher Education sector has witnessed a tremendous increase in the number of Universities/University level Institutions & Colleges since Independence. The number of Universities has increased 34 times from 20 in 1950 to 677 in 2014. More specifically if we talk about technical institutions, their number has gone up from 1,511 colleges in 2006-07 to an astoundingly high 3,345 in 2014-15.
India now ranks second after China in terms of enrolment of students. The government has set a target to achieve a Gross Enrolment Ratio (GER) of 30% by 2020. But, the question arises, that is it sufficient to increase the number only?
It is true, that given with scale and complexity of the higher education challenges, the government on its own cannot single-handedly tackle all the issues but at the same time we all have to accept that majority of private technical institutions in India are Lacking in infrastructure, sufficient laboratory equipment, trained faculty, Research & Development, industry oriented curricula and theory- practical balance. They are producing large number of graduates with technical degrees but with no technical skills and who is not industry deployable. Continue reading
Mr Manish Gupta* from Pratap Nagar Jaipur wanted to get her daughter admitted in an undergraduate program in one of the best Engineering Colleges in Jaipur. Ms Shreya Gupta* studied in one of the best CBSE schools in the Mansarovar area in Jaipur city and achieved A1 grade in recently concluded 10+2 exams. Although Jaipur is emerging as the top choice for engineering aspirants due to existence of prestigious institutions such as MNIT Jaipur, LNM-IIT Jaipur, and JK Lakshmipat University Jaipur, in addition to several other Universities. As Rajasthan Pre-Engineering Test (RPET) will not be held this year, it is becoming even more challenging to choose right engineering college. Like Mr Manish Gupta, there are several parents and students seeking possibility of admission for their wards. Are you interested to study engineering and technology program in Jaipur? Or are you looking for a value based engineering college in Rajasthan? If yes then, how to choose a best engineering college in Rajasthan or best engineering college in Jaipur? It has been observed that our choices are often based on what others are choosing and not what we like? Or what we wish to become in future? Or what excites us as an individual? Or where I want to reach professionally in industry after 10-years or 20-years?
So the question remains, how to choose the best institute of engineering and technology (IET)? Actually, one may consider the ranking of an IET or University given by an independent agency. However, the anonymousness, exhaustiveness, and transparency of these accreditation agencies remains questionable.
