Abstract

As a group, the individual investors are bigger than other groups of investors in Indian stock markets, such as institutional investors, corporate investors etc., in terms of both number and value of trades in Indian stock markets. Our research indicates that the investment and trading decisions of the individual investors are driven by psychological biases well-documented in psychology literature, rather than by rational investment motives. We also identify the nature of the biases. A dominant bias is to consider zero return a natural threshold for their investments. As a result of the biases, the individual investors systematically lose to institutional investors, resulting in a massive wealth transfer. Our research findings are based on evidence from actual trading records of all investors in the National Stock Market (NSE) over a long period.

Abstract

Till the 16th century Europe and India had a similar level of development. Both the continents were under a deep religious influence. But In the 16th century Europe went in a different direction, in that the sphere of Religion got separated from philosophy and science, and the age of Rationalism emerged. In Europe this crucial intellectual change paved the way toModernity. This did not happen in India. Modernity, basically a European phenomenon, propagated three fundamental Ideas: Freedom, Equality and Individualism based on the principle of rationality.

India’s entry into scientific Modernitywas hampered by the caste barriers of Brahmanism, whichdid not allow any social institution, which has public participation. Therefore, till the arrival of the British,India could not cultivate the idea of University, which promotesmass education and opens its gates to all members of the society. At the most, India remained at the level of Gurukul, which wasmeant only for the privileged class. It ignored the areas of science and technology.Whereas all European languages have the status of “knowledge language”, no Indian language is capable of writing a Ph.D. thesis in natural sciences, engineering or medicine. Particularly the indigenous scientific and technical expertise of the Indian artisans and its scientific and technical vocabulary was never accepted and therefore not included in the dictionary. This exclusion of the Indigenous knowledge has created a deep social bias against our skilled workers like blacksmiths, cobblers, barbers, masons, carpenters, farmers etc. Unlike in Europe their professions are looked down upon by the upper castes reminding us of the controversy over the title of Shah Rukh Khan’s film called “Billu the Barber”, protesting against the epithet ‘Barber’, which has acquired an inner meaning of an abuse to the community of hair dressers. Due to this epithet the members of this community are made to feel ashamed of their legitimate and creative profession. This social injustice needs to be addressed through critical reflection and affirmative action.

Abstract

Students, especially those who opt for technological courses aspire to develop some good outcome from their education. Institutes of technologies also claim of imparting knowledge that is more practical in nature and has application of theories. However for a long time, students are trained for monotonous jobs which can be applied for a factory setup and has very less association with the day-to-day problems, requirements, and business opportunities existing in our society. Such opportunities are harnessed by industries from outside India. Through Design we can train students to harness such opportunities in society as well as engage them in work which is not monotonous in nature along with imparting practical education. Design trains students how to devise and produce objects, artifacts, interactions and systems in response to economic, technical and social needs and desires. It is a rich combination of experiences in imaginative creativity, the humanities and the sciences, with an aptitude of application of the knowledge for benefit of people. Such courses cover design education in general. Students can further be nurtured in the field of Product Design, Automobile Design, Interaction Design, and Design for special needs, Film and video Design, Animation Design.

Abstract

The speaker discusses basics of climate system, global energy balance, trends in greenhouse gases, observed changes in the present climate system, details of the Earth System Models, associated Physics and numerical methods, and future climate change projections. The Earth’s climate system is in equilibrium as the incoming solar radiation is balanced by the out-going long wave radiation from the earth. Any imbalance of this equilibrium can change the global energy balance and can cause changes in different components of the climate system. Due to anthropogenic activities like industries, concentrations of greenhouse gases like Carbon dioxide, methane, nitrous oxide are increasing. This increase of greenhouse gases causes trapping of out-going long wave radiation that increases surface air temperatures, thus global warming. Associated with the global warming, there are many changes in different components of the climate system as we have observed from instrumental data. As greenhouse gases are further increasing, we should expect further warming and thus many associated devastating consequences. Climate scientists use Earth System Models to understand the past and future climate. Earth System Models are mathematical models which use the dynamics and physics of different components of the Earth System, like atmosphere, hydrosphere, lithosphere, cryosphere and biosphere. The physical processes are included in the model using parameterization methods. The climate change simulations are made using Earth System Models with the help of large high performance computers.

Abstract

The total losses of medium voltage power semiconductor devices are dominated by switching losses. Operating at very low switching frequency is therefore mandatory. Low switching frequency can be achieved by using multilevel inverter topologies, optimal pulsewidth modulation techniques and, at very high power, by using series connected inverter circuits rather than series connected devices. The latter generate additional losses in their voltage balancing circuits. Parallel connected devices lead to higher currents, and consequently to higher losses. Using these guidelines, various inverter topologies are discussed. Optimal pulsewidth modulation can be achieved by off-line optimized pulse patterns, combined with online optimization at transients. An alternative approach is predictive control which is presently attracting the interest of many researchers. A predictive algorithm directly generates the firing pulses of the inverter as part of a closed loop current control system, thus eliminating a pulsewidth modulator. A gate pulse is generated whenever a predefined current error is exceeded. That error is computed as the difference between reference and actual current space vector. The next switching state is then determined such that maximum time elapses until the error vector exceeds its limit again. This minimizes the switching frequency and also the switching losses. Overmodulation and a smooth transition to full-wave operation produces maximum inverter output voltage. The error vector is represented here in a rotor field oriented coordinate system and different error magnitudes are permitted in the respective axes.

Abstract

The talk's focus is on India's competitive capabilities in global markets, particularly those dealing with Technology. Strategic Advantages enable a country to enjoy market success, or even dominance, in the long-term. In our contemporary world, Technology is the key to achieve Strategic Advantages in global markets. The basic types of Strategic Advantages obtained and enjoyed through the relevant Technologies – not just through their market perception (more dominant in the short-term) but in their experienced reality (more valuable for the long-term) – are all ultimately based on the fundamental principle of Value Differentiation. Cost Leadership, Unique or Distinctive Functionalities, Value for Money, Market Entry Timing, Market Niche Choices, Strategic Alliances, etc., or any combination of these, which are widely discussed in the literature, are all specific modes and manifestations of Value Differentiation. For realizing competitive advantages we must carefully choose and understand the Markets we wish to compete in and the Value needs of Customers in those Markets. Concurrently, in the larger context of different basic human necessities, viz., safety and security, health and wellness, education, housing, clothing, communication, transportation, entertainment, adventure, etc., we must identify the scope for strategic advantages that can be realized through Technologies. A deeper understanding of Value will then enable us to correctly identify the competitive components embedded in Technologies that we must imagine, conceive, develop and sell successfully in global markets through systematic, effective R&D and Product management practices.

Abstract

Ever since Charles Darwin published his seminal book, “On the Origin of Species by means of Natural selection” in 1859 the question has been asked how humans evolved. Over the last 150 years, the picture of human evolution has become increasingly clear, with its origin being in Africa some 2.5 million years ago, starting with an ape-like species called the Australopithecines (“Southern Ape”), and evolving through many stages of the genus Homo (“Man”) till our own species called Homo sapiens (“Intelligent Man”). The last stage of this evolution, which involved the disappearance of archaic human types like the Neanderthals, is still a subject of much controversy.

Abstract

We are in a connected world but the connection is insecure. We want to communicate with each other but we are poles apart. Finally we want to exchange information but no one else should know on the same. The insecurity in the network allows one to impersonate as someone else and this calls for addressing a fundamental issue in a communication network. How do I know I am talking to intended person? Equivalently, how do I convince the other party that I am indeed the person I am claiming the one to be .... In sum, in remote communications, identification of the parties are as important as the messages that are communicated. Our focus is on identification or establishing the identity of an entity. So, there are Provers and Verifiers. One of the basic concerns of Prover is that his act of convincing Verifier should not enable the Verifier to impersonate as Prover to a third party!! How do we address this issue? One of the ingenious, award winning solutions devised for the above conundrum is called "Zero Knowledge protocols". This talk aims to explain this concept to a broader class of audience.

Abstract

The spectacular splendour of lightning becomes an hazard of nature at times. The phenomenon, as old as this earth, is common in other planets of the universe too. It has always been attracting scientists, especially the physicists, all over the world to study, understand and evolve methods to tame this natural phenomenon in order to overcome its harmful effects. The development and propagation of lightning discharge and the mechanism of every damage caused by lightning is unfortunately still not well understood hence not thoroughly explained. This presentation attempts to describe the mechanism of the development of lightning as studied and understood by the investigations made in high voltage engineering laboratories. It explains the preference of locations for the lightning to strike upon and the types of damage it can cause depending upon the location and the situation. Methods of protection from lightning are also explained. Ball Lightning, a phenomenon related to lightning but not known very widely, is described. Case analyses of the incidents of lightning strikes and ball lightning investigated by the author are presented.

Abstract

Safety critical structures such as those in aerospace, nuclear, automobile and bridges need continuous monitoring to ensure no damages initiate and propagate leading to catastrophic failures. Structural Health Monitoring (SHM) is the field which emerged from this crucial requirement and is highly inter-disciplinary. The developments in Micro- and Nano sensors/systems made such an approach feasible. The field needs expertise in computational methods, novel materials, non-destructive testing (NDT), sensors and computer science. In aerospace vehicles the measurements are carried out in flight by HUMS (Health Usage Monitoring System) and the fatigue damage is estimated at critical locations. Off-line SHM primarily depends on NDT for damage detection and tolerance limits to assess the health of the structure. This activity is of considerable importance to maintenance and repair operators. Thus the SHM activity can be viewed as comprising of diagnosis and prognosis. Diagnosis deals with damage detection and prognosis analysis depends on damage growth. The design philosophy used for several decades based on Fracture Mechanics, Fatigue and Damage Tolerance is now leading to SHM/IVHM (Integrated Vehicle Health Monitoring). Besides describing the broad scope of this field, the lecture also presents some recent work on non-linear prognosis analysis of cracks in fastener structural joints.

Abstract

The all-too-familiar chirp of field crickets is actually a song that male crickets sing to attract mates. Surprisingly, this rather loud song is not produced by vocal chords of crickets; it is produced by very well coordinated motions and vibrations of an ensemble of clever natural transducers. These purely mechanical transducers with critical micro-scale features must work with clockwork precision to produce songs with a few KHz central frequency in a specific frequency band allocated to the particular species (yes, crickets have spectrum allocation too!). The song production unit uses another transducer as a frequency multiplier to convert the slow wing beat frequency into a high frequency impulse train. The impulse train, in turn, forces the harp—a thin triangular part of the wing—into resonance, modulating the subsequent motion into a beat pattern to produce the characteristic song. In this talk, I will unravel the orchestra of the transducers behind the song production that we have been studying for several years. Our study involves a careful finite element model of the harp, measurement of its material properties using sophisticated experimental techniques such as nano-indentation and atomic force microscopy, multiple simulation runs to get the vibration response of the harp, and finally, a comparison of the sound produced by the model with the sound recorded from the field crickets. The uncanny resemblance of the sound and the comparison of the frequency content provide enough evidence for trusting the model. We subsequently use our model to discover a scaling law that crickets seem to use for “spectrum allocation”. The scaling law predicts geometric scaling for the harp structure that the evolutionary processes seem to have used for crickets of different sizes in order to enable them to produce songs with frequencies unique to the species. The underlying design principles for low frequency driving, frequency multiplier, and vibration amplifier have bearing on micro scale devices and are likely to be used for development of efficient MEMS loudspeakers.

Abstract

The Institutional education in engineering started from the requirements of firmly establishing colonial rule of the British Government with all its economic benefits. After independence, IITs were set-up to lead postgraduate education and research in engineering but it could not find time from ‘global’ problems to address either national or local problems of Indian society. Twenty first century has brought significant changes in the industrial scenario demanding new types of engineers, who should be ‘smart creative’. The curriculum needs to evolve to incorporate such elements as required in the making of suchengineers. The delivery of the curriculum through teaching must result in appropriate transformational learning so that a students may become ‘smart creative’.

Abstract

The Nobel Prize in Chemistry (2014) was awarded to Erik Betzig, Stefan W. Hell and W. E. Moerner for their pioneering work on single-molecule imaging and super-resolution fluorescence microscopy. 1-3 Fluorescence microscopy, before this breakthrough invention, was just limited to the diffraction limited optical barrier, even for nm-sized objects. This development is expected to revolutionize, especially in biology and medicine, the quantitative dynamic description of the cellular components that define the phenotypes of all life forms. In this seminar, we will provide a general understanding of the principle of super-resolution microscopy and its real-world application.

Abstract

In this popular talk, we will give an overview of the exciting new field of Brain Machine Interfaces (BMI). The goal of BMIs is to "read" the mind of a person albeit in a limited sense. For example, by recording signals from the brain, one attempts to infer what kind of motor action a person wishes to perform. This research is interdisciplinary in nature and involves neuroscience, mathematics, robotics, signal processing etc. This research can be applied to help paralyzed patients, amputees and others.

Abstract

In our everyday 3‐dimensional world, we are continuously interacting with 2‐dimensional surfaces, and they play a major role in our lives. For example, the cleanliness of optical lenses, the feel of fabrics, the resistance of biomedical implants towards bacteria, the speed of computer hard disks, automotive exhaust catalysts, self‐ cleaning windows, and even the wear of car brake pads are all governed by their surface functionality. The worldwide market for functional surfaces exceeds $100 billion per annum (US Department of Energy), and a key driver is the added value that can be imparted to commercial products by tailoring their surface properties (quite often by just changing the few outermost atomic layers – high value / low volume manufacturing). In order to generate such surfaces, there exists no shortage of methods, however such techniques suffer from drawbacks including substrate‐specificity (cannot be easily adapted to different materials or geometries) and environmental concerns associated with the utilization of solvents, strong acid / base media, and heat. An innovative scientific solution will be described which addresses these issues and yields remarkable levels of surface functionality at low cost with negligible waste. This has entailed building a multi‐disciplinary approach (physics, chemistry, biology, engineering, and computer science) in order to develop a wide spectrum of targeted end‐user applications; these include liquid‐repellency, rewritability, cell tissue engineering, adhesion, gas barrier, tribology, anti‐fouling, opto‐chirality, catalysis, inkjet printing, antibacterial, drug release, water purification, DNA computers, and nano‐actuation. This fundamental research has led to the filing of 38 patent families and the establishment of 3 start‐up companies (Surface Innovations Ltd, Dow Corning Plasma Ltd, and P2i Ltd – winner of 2012 International Business Award for 'Most Innovative Company in Europe').

Abstract

The existence of astrophysical black-holes as an end-state for massive stars is a striking finding of Einstein’s theory of general relativity. This lecture introduces basic concepts that characterize black-holes, viz. their Schwarzschild Radius, Event Horizon, Hawking Radiance, etc.. The formation of black-holes through gravitational collapse by overcoming of the quantum degeneracy pressures will be discussed. The types and classification of black-holes based on their mass and energy content will be introduced. The Four Laws of Black-Hole Mechanics formulated by Bardeen et al. (1973) & their similarity with the 4 Laws of Thermodynamics will be enunciated. Thereafter, thermodynamic (energy & entropy) analysis of the simplest Schwarzschild black-hole fed by the Cosmic Microwave Background Radiation (CMBR) will be introduced (Mahulikar & Herwig, 2012, 2013). The lecture will finally give a glimpse of the current research on this topic at IIT-Mandi, on the proposed new relation between black-hole’s negentropy and its event horizon (Mahulikar, 2014).

Abstract

According to ITRS-2011, one of the most prominent challenges for promoting EUVL are the requirements for improvements in resist performance like sensitivity, resolution, etch resistance and line edge roughness (LER) to fulfill the demands of high-volume production. The chemically amplified resists (CARs) can limit the ultimate minimum half pitch resolution due to acid diffusion problems and post exposure instability especially for features at 16 nm and below. For this reason, recently attention has focused on the development of non-chemically amplified resists (n-CARs) for future lithography nodes.

One such approach being investigated by us is the development of polymeric non-CA negative photoresists for sub 16 nm technology. Novel n-CAR negative resists were synthesized and characterized for EUVL applications, as they are directly sensitive to radiation without utilizing the concept of chemical amplification. The n-CARs achieved 20 and 16 nm L/2S, L/S patterns to meet the ITRS requirements. High resolution patterning of designed polymer resists was carried out using 20 KeV e-beam and EUV lithography. High resolution features at 13.5 nm obtained at BMET tool Berkeley will be presented as well as fragmentation dynamics under EUV at the Synchrotron Light Source (103.5 eV) at Campinas Sao Paulo Brazil. These new negative tone resist provide a viable path forward for designing non-chemically amplified resists that can obtain higher resolutions than current chemically amplified resists at competitive sensitivities.

Abstract

Foreign policy is a country's policy, conceived, designed, and formulated, to safeguard and promote her national interests, in her external milieu, in the conduct of relations with other countries, bilaterally and multilaterally. It seeks to turn the external environment conducive to the country's goals, through building widest possible international cooperation. The two principal foreign policy goals are security and prosperity. Foreign policy transcends all various areas of interaction - ever on the rise.

In foreign relations, diplomacy and tact are the first line of defense, whereas force and military the last resort. In a democratic polity, the three important sources of input for foreign policy formulation are the executive and the bureaucracy, the legislature, and independent public opinion including the media.

India had an age old indigenous foreign policy tradition, but not consistently all through. The major interregnum was the British colonial rule, but the freedom movement helped revive it, led by Nehru and others, who evolved among others the non-alignment concept, to safeguard India's strategic autonomy and enlightened self-interests, aimed at helping the nation-building without distractions, and ensuring peace and security. The principal tenets of India's foreign policy towards these objectives, and to project her as an open, inclusive, and responsible member of the global community, are moored in her civilisational beliefs of peace, tolerance, and One World.

The end of the Cold war and India's economic reforms around 1990, in a new rapidly evolving international landscape, opened up new significant opportunities for India, even in the face of new and major challenges. The new situation warranting a paradigm shift in the international cooperation pattern underscored a much bigger role for a country like India in collective tackling of these challenges. The spurt in capital and trade flows was directly beneficial too. India had arrived at a most favorable juncture in her quest to develop. The developing countries now followed India's lead and the developed countries sought her counsel and cooperation. India emerged as a major voice in global decision-making and management, and as a bridge and balancing power in the emerging global strategic architecture. Repeatedly India reached out swiftly particularly to the neighbours to provide assistance, in emergencies and otherwise too. India has demonstrated her ability to contribute to regional and global peace and security, to social and economic progress, all through true democratic governance. The civil nuclear cooperation agreements concluded with USA and others in recent years was a major success of India's foreign policy, ending the long nuclear apartheid against her, but without diluting India's firm opposition against nuclear weapons on a universal basis. Today India has formal diplomatic relations with most nations, with her relations with the major powers having acquired strategic depth and self-sustaining mutuality of interest.

In her neighbourhood, India is a particular factor for stability and peace, in her effort to construct an overarching vision for the region, developing friendly and cooperative relations with all her neighbours, and creating stakes in each other's prosperity and stability, predicated on India's greater responsibility in the process as the largest country and the strongest economy in the region, while encouraging all countries to be sensitive to one another's vital concerns. Recent times have witnessed particularly significant advances in regard of these, and in meeting the challenges, with Pakistan and China, as well as with Bhutan, Nepal, Sri Lanka, Bangladesh, Maldives, Afghanistan, and Myanmar. SAARC represents India's commitment to the region's progress and socio-economic development.

Further beyond, India has pursued policies to create new cooperation opportunities and partnerships in the Asia-Pacific, West Asia, Africa, Latin America, and through new significant groupings such as BRICS. India's development cooperation and partnerships have evolved, too, extending credits, technical and other cooperation to a large number of countries, to the tune of well exceeding one billion dollar annually. International terrorism, a major threat to peace and stability, has posed particular challenge to India; India's leadership and initiatives to build more effective international cooperation against terrorism, as well as weapons of mass destruction, have scored some significant successes. India has a steadfast commitment to the UN and its objectives, playing a most active and constructive role, in various multilateral fora. In order to address the glaring deficiencies and inequities of the global governance, India has been in the vanguard for reforms, particularly of the UN and its Security Council, offering herself as a new Permanent Member, which has drawn a very wide support, even though the process is yet not near a satisfactory conclusion. Global warming and climate change are another major global concern where India's role to evolving a global consensus, on the basis of equity and fairness, has been widely welcomed. An important role of India's foreign policy remains to ensure welfare and well being of the 30-million strong Indian Diaspora, and fostering their stronger links with the mother country.

Today's world needs a new international consensus, predicated on multilateralism, democracy, and inclusive participation, tolerance, understanding and acceptance, to deal with a variety of new and complex challenges. India will continue to strive to build an enabling order, based on equity and reality. The rapid qualitative change in India's foreign policy perspectives are also a positive development for international peace and stability. India would be an indispensable player in strengthening peace, stability and prosperity everywhere.

Abstract

What is light? How does it travel from one point to another?

How does light travel from one point to another? Mach’s Principle was the motivating idea for Einstein to develop the General Theory of Relativity. The General Theory predicts that light travelling in the Celestial space would bend while passing close to the Sun. On a terrestrial scale, light bends when passing from one medium to the other or travelling through inhomogeneous media. Is there a common principle followed in both cases? In order to explore this possibility, we develop a general discussion by asking the question that in going from one point to another, weather (a) light travels in a straight line, or (b) it chooses the shortest path, or (c) it chooses a path to reach the target point in the minimum time (Fermat's Principle).Through a description of some surprisingly simple experiments we conclude that light always chooses the shortest path as it does in outer celestial space as enunciated by Einstein. In this description, the length scales change but the time intervals remain the same as light passes from one medium to another. This is a refreshingly new way of looking at the refraction of light.

“What is light?” Is it a stream of particles called `Corpuscles' as proposed by Newton or is it a wave as described by Huygens? Once again, we depend on a very simple experiment done by almost every science high school student to conclude that light certainly does not consist of the ‘Corpuscles’ described by Newton. We consider next the Einstein’s concept that light can be considered as a stream of particles called ‘Photons’ and show that this picture is also in agreement with the experimental results of the same simple experiment. We thereby confirm the dual nature of light. The discussion leads us to a refreshingly new visualization of Nature as consisting of finite mass Newtonian particles as well as the Zero mass Boson called ‘Photon’. In this way we ascribe the discovery of the Zero of the mass scale to Satyendra Nath Bose.

We mention some more mysteries of light and conclude by discussing that incorporation of concepts and principles have the potential of generating more interest and discussion among the students than by simply enunciating the Laws of Physics and facilitating their use in problem solving.

Birla award, the Prix Janssen of the French Astronomical Society and an Associate of the Royal Astronomical Society of London. He is Fellow of the three national science academies as well as of the Third World Academy of Sciences. Apart from his scientific research, Narlikar has been well known as a science communicator through his books, articles, and radio/TV programmes. For these efforts, he was honoured by the UNESCO in 1996 with the Kalinga Award.

Narlikar recently broke new grounds in space research. Since 1999 he has been heading an international team in pioneering experiments designed to sample air for microorganisms in the atmosphere at heights of up to 41 km. Biological studies of the samples collected in 2001 and 2005 led to the findings of live cells and bacteria, thus opening out the intriguing possibility that the Earth is being bombarded by microorganisms some of which might have seeded life itself here.

Narlikar was decorated Padmabhushan in 1965, at the young age of 26. In 2004 he was awarded Padmavibhushan. In 2011, the Government of the State of Maharashtra gave him the State’s highest civilian honour of Maharashtra Bhushan.

Abstract

This talk will begin by a historical introduction to the topic of cosmology describing how as a scientific discipline it has sought to emphasize facts. The present big bang cosmology, often described as the ‘standard model’ also started that way. However, of late several speculative elements have entered the subject. These, like inflation, non-baryonic matter and dark energy will be briefly described. It will be argued that the last word in the subject has not yet been said and there should be room for alternative ideas.

Topic: The Internet without IP addresses - A new approach to the Internet Architecture

Abstract

There has been concern over many years about the growth of the Internet and the ability of the Internet Protocol to provide new functionality that was not part of its original design. For example, concerns over scalability have been related to routing table growth in the default free zone (DFZ). Additionally, users would like to have harmonised functionality, such as mobile hosts and networks, packet-level security, and multi-homing. Many of the solutions for dealing with scalability and new functionality have been designed and implemented in isolation, as engineering retro-fits to the core IP functionality, and so do not operate well when used together. We take a fresh approach to the architecture of the Internet, looking at the general concept of naming to provide scalability and harmonised functionality. This talk will introduce the Identifier Locator Network Protocol (ILNP) as a way of realising this new architectural approach. The architectural change with respect to the current Internet will be explained, as well as an outline of how the new architecture can be engineered for today's networks.
