Platform for chip designing

Calcutta:

IIT Kharagpur is exploring the possibility of using a platform developed by a group of researchers at the University of California, Berkeley, that can be freely used for designing semiconductor chips.

In the foreseeable future, Digital India will need application-specific chips in every conceivable domain but today only a handful of companies have the ability to design integrated circuits (IC).

Inspired by the success of open source software, SiFive, a US-based company, aims to change the ecosystem of chip design by promoting OpenSilicon – a platform where pre-designed open source components can be stitched together to design customised ICs.

The OpenSilicon platform already provides the open source RISC-V processor developed by the researchers at UC Berkeley.

Recently, SiFive hosted an academic symposium at a city hotel, where cost-effective ways to design and fabricate semiconductor chips were discussed threadbare. The symposium was attended by professors from IIT Kharagpur.

Later, the academics explained the significance of the conclave.
Designing semiconductor chips require sophisticated and expensive software tools or CAD tools and years of experience. Chip fabrication costs are astronomical. For any start-up that wants to get into custom chip designing, the costs and skill requirements are difficult to overcome.

“It is a promising initiative. Offering open source pre-designed components through a cloud-based design framework has the potential to bring down the design cost. Also, bundling multiple custom ICs in a single fabrication cycle can help in sharing the fabrication costs among the partners,” said Pallab Dasgupta, dean, Sponsored Research and Industrial Consultancy, IIT Khargpur.

Dasgupta is also a professor in the department of computer science and engineering with years of experience in electronic design automation.

The IIT has an advanced chip design laboratory since 2000, which has successfully designed and tested more than 100 chips with its fabrication partners. It carries out research for top global semiconductor and EDA companies.

SiFive is aiming to let more start-ups use its platform to minimise the cost of developing semiconductor chips and rid the chip design industry of the proprietary regime of a handful of wealthy companies, said Yunsup Lee, co-founder and chief technology officer (CTO) of SiFive.

“India is home to some of best research and educational institutions in the world. We are honoured to host presentations from the academic luminaries who are on the frontlines of innovation and research in the areas of machine learning, hardware verification, circuit design and more,” said Yunsup, who delivered a lecture at the symposium.

When Metro asked him to explain what prompted the company to hit upon the concept of looking beyond the proprietary regime, Yunsup, who has done his PhD from UC Berkeley, where he co-designed the RISC-V ISA and the first RISC-V microprocessors with Andrew Waterman, said: “At the University of California, Berkeley, we believe in taking the technology to a larger pool of users so the technology can do greater good. This was developed during our student days. With this motto in mind, we are touring 20 cities across the globe to popularise the concept.”

IIT Kharagpur director Partha Pratim Chakrabarti, who attended the session, said: “The concept they have floated is innovative. We are holding talks about a tie-up that the company has proposed.”

Machines, made in school

The teenagers from Bijoygarh Higher Secondary School for Girls had never seen a remote-controlled car before. Neither had they heard of artificial intelligence. So they were extremely happy unravelling the wonders of science in the Atal Tinkering Laboratories (ATL) of Salt Lake School.

ATL is an initiative under Atal Innovative Mission, programmed by Niti Aayog, or the National Institution for Transforming India, a policy thinktank of the central government. Under the scheme, the government provides selected schools with grants to set up science laboratories. The idea is to encourage entrepreneurship through self-employment and to develop scientific interest in students. Over 2,000 schools in India have established laboratories under this initiative, including 68 in West Bengal. Salt Lake School is one of them.

The ATL lab in our school was inaugurated in December by the vice chancellor of Jadavpur University, Suranjan Das. Since then, and even before that, 20 students of our school have been working hand-in-hand to create products of scientific importance with utmost precision and dedication.

For many months, ATL had been an intra-school platform, enlightening students on the importance of robotics, cloud computing, programming, coding, artificial intelligence and more.

Finally we opened doors to students of other schools, in observance of ATL Community Day, to commemorate the birth anniversary of B.R. Ambedkar. Our school worked with Maya Foundation, a non-profit NGO that works to create awareness regarding menstrual health of adolescent girls and for the downtrodden sections of rural Bengal. They helped us welcome 12 girls from Bijoygarh. Some students of Salt Lake Point School also attended the exhibition.

As head boy of our school, I watched over my juniors working hard to make the event a success. “Innovation for all” was our motto and we gave it our best shot. My juniors demonstrated remote-controlled cars, which can be used for fire detection, and if fitted with small cameras, can help in investigation purposes. The remote was a mobile phone, and many of the girls from Bijoygarh tried operating it themselves.

The sight of their excited faces at the sight of the moving car was perhaps my moment of the day.

Aditya Mitra, a budding scientist from our school, demonstrated his hand-made laptop. He had built it with spare parts of other electronic gadgets. “Khub bhalo,” was the general reaction from guests, when I asked them to comment on the expo. They interacted with our students and enquired about making the gadgets and the principles working behind them.
The students from Salt Lake Point School were curious and eager too. “There are so many things we didn’t know earlier,” said one of them. “It has been a wonderful experience, getting to see and learn so much.”

Our students, too, were happy to showcase their hard work and explain the intricacies of their machines.

The exhibition was preceded by the inauguration ceremony, attended by scientist Chittaranjan Sinha. Speaking to the students, he emphasised on the importance of scientific innovation and new thinking to sustain our environment and asked us to help society on a wider scale. He encouraged students by telling stories from the lives of Acharya P.C. Roy and Acharya J.C. Bose. “India today is in the grip of grave disarray with superstitious beliefs reigning. Only scientific and rational thinking can save the nation,” he said.

MLA Sujit Bose spent time with us too and congratulated the students and the management for organising the event. Our principal, Sugata D’Souza delivered the vote of thanks and emphasised that this ATL laboratory shall be the nucleus for the development of a scientific temper in students of schools in our region.

How Cannabis Jumped from ‘Colonial Science’ to Western Medicine – in Calcutta

William Brooke O’Shaughnessy’s investigations at a Calcutta hospital into the potential of medical marijuana were the first in modern medicine.

In 1833, a twenty-four-year-old Edinburgh graduate arrived in India, an Assistant Surgeon in the East India Company. He had failed to acquire a license under the London College of Physicians and Surgeons, but had already established himself as an exciting young medical researcher, authoring an important paper on cholera following an outbreak in Europe. This man was William Brooke O’Shaughnessy, an Irish physician who would – over the next few years working in India – make significant contributions to the history of research in electricity, telegraphy, pottery, and, his primary discipline, medicine

The colonial peripheries had no shortage of impressive polymaths, but what sets O’Shaughnessy apart is the manner in which, while conducting research in his many areas of interest, he not only tapped into elaborate local knowledge networks and structures but also rigorously documented them, thoroughly crediting his sources both bibliographic and human. O’Shaughnessy also stands out on account of what was, arguably, his most significant contribution to medicine: the claim that cannabis could be used as a medicinal drug.

As an intoxicant cannabis was fairly common in India, as O’Shaughnessy noted, but he demonstrated its potential use in a medical context, particularly as an anaesthetic. The papers on his experiments with the plant were published in the Journal of the Asiatic Society of Bengal in late 1839 — and were also read in front of the Medical and Physical Society of Calcutta in October of that year. In them, we find detailed records of his prescient experiments and a fine example of his unique style of research.

His first series of cannabis experiments were conducted on an unfortunate menagerie of animals (amongst others, fish, vultures, and storks) and also, perhaps not without controversy today, a few children — all subjected to various preparations and extracts of Cannabis Indica. The first experiment, for instance, involved administering “ten grains of Nipalese [sic] Churrus, dissolved in spirit” to a “middling sized dog”. O’Shaughnessy’s breathless notes read: “In about half an hour he became stupid and sleepy, dozing at intervals, starting up, wagging his tail as if extremely contented, he ate some food greedily, on being called to he staggered to and fro, and his face assumed a look of utter and helpless drunkenness.”

O’Shaughnessy then proceeds to try variants of these initial treatments on a number of maladies. He describes the effect on four cases of patients suffering from rheumatism, a case of hydrophobia, on cholera and tetanus, before issuing a warning about the delirium that may be occasioned by inappropriate dosage. Some of the reports wouldn’t be out of place as descriptions of a merry stoner’s night in (minus the video games). One rheumatism sufferer, to whom “half a grain of Hemp resin was given in a little spirit … became talkative and musical, told several stories, and sang songs to a circle of highly delighted auditors, ate the dinner of two persons …, sought also for other luxuries I can scarcely venture to allude to, and finally fell soundly asleep, and so continued till the following morning”. Perhaps not unsurprisingly the next day the patient “begged hard for a repetition of the medicine”.

Elsewhere O’Shaughnessy describes a somewhat surreal episode in which a rheumatism patient administered with cannabis enters a state of “catalepsy”, whereupon his rigid limbs could be moved only with the help of medical staff, who could place them in “every imaginable attitude” where they would remain “no matter how contrary to the natural influence of gravity” — all the while the patient remaining completely “insensible”. The commotion of events ended up rousing a second patient, similarly dosed, who became “vastly amused at the statuelike attitudes” he witnessed, and then proceeded, after a sudden “loud peal of laughter” to exclaim that “four spirits were springing with his bed into the air”. After a subsequent “uncontrollable” fit of the giggles this second patient then took up the strange condition of the first, his arms and legs “remain[ing] in any desired position”. Despite the slightly chaotic scenes, within a day or so both patients were much relieved of their rheumatism, and in three days completely cured.

Interestingly, it is while recording a failed treatment of hydrophobia that O’Shaughnessy notes one of the fundamental arguments for this medicine: even if it failed at curing the actual root of the illness, “at least one advantage was gained from the use of the remedy — the awful malady was stripped of its horrors”. If the illness was terminal, at least cannabis could enable the physician to “strew the path to the tomb with flowers”.

The argument is not unfamiliar today, and indeed, in a prescient echo of more recent advocates of cannabis’ legalisation, O’Shaughnessy also downplays the drug’s supposed negative effects compared to other certain popular legal narcotics.

As to the evil sequelae so unanimously dwelt on by all writers, these did not appear to me so numerous, so immediate, or so formidable, as many which may be clearly traced to over-indulgence in other powerful stimulants or narcotics, viz. alcohol, opium, or tobacco.

The interest of O’Shaughnessy’s medical students was also clearly piqued. He reports that several ended up experimenting on themselves and describes in detail one particular auto-experiment by a “retiring lad of excellent habits” which, twenty minutes after ingestion, led to the “most amusing effects I ever witnessed”.

I found him enacting the part of a Raja giving orders to his courtiers; he could recognize none of his fellow students or acquaintances; all to his mind seemed as altered as his own condition; he spoke of many years having passed since his student’s days; described his teachers and friends with a piquancy which a dramatist would envy; detailed the adventures of an imaginary series of years, his travels, his attainment of wealth and power. He entered on discussions on religious, scientific, and political topics, with astonishing eloquence, and disclosed an extent of knowledge, reading, and a ready apposite wit, which those who knew him best were altogether unprepared for. For three hours and upwards he maintained the character he at first assumed, and with a degree of ease and dignity perfectly becoming his high situation. A scene more interesting it would be difficult to imagine. It terminated nearly as rapidly as it commenced, and no headache, sickness, or other unpleasant symptom followed the innocent excess.

In and amongst these colourful accounts, O’Shaughnessy’s paper is peppered with references to other instances in which his fellow medical men had employed the administration of cannabis to alleviate patients’ symptoms. The list includes his cousin Richard O’Shaughnessy, Dr Bain of the Police Hospital, Mr O’Brien of the Native Medical Hospital, and not least, James Esdaile (another Edinburgh student, best known for his experiments with mesmerism at the Hooghly Imambarah College, which he recorded in his 1851 book Mesmerism in India). The historian Shrimoy Roy Chaudhury feels that it was the “conquest of pain in surgery” that granted British medicine historical credibility in India. Hemp played a key role in this. And veterinary science got involved as well — among notable experimenters in this field being the firm Hughes and Templar, who claimed to have cured three out of “five cases of horses suffering from tetanus” with the hemp resin.

Before setting out the details of his experiments, O’Shaughnessy offers a background to the drug in four sections: its botanical character, popular uses, historical details, and medicinal properties. But he does all this with a little help from his friends: some regular and some, as that other great “generalist” Sherlock Holmes would call them, irregular. The network, as the following series of annotations to O’Shaughnessy’s article will demonstrate, is an incredibly wide and diverse one.

For the historical and statistical data he thanks the following: “the distinguished traveller the Syed Keramut Ali, Mootawulee [guardian] of the Hooghly Imambarrah”, “Hakim Mirza Abdul Razes of Teheran”, Pandit Madhusudan Gupta, “the celebrated Kamalakantha Vidyalanka [sic], the Pandit of the Asiatic Society”, and Mr DaCosta.

Syed Keramut Ali, former Great Game “Newswriter” under Arthur Conolly in Kandahar, helped O’Shaughnessy with Persian references and a few manuscripts. Additional translation help may have also come from “Mr Da Costa”, which is presumably Lewis Da Costa, a polyglot and a prolific translator serving as Assistant Persian Translator to the Government of India in the 1840s. O’Shaughnessy wished also to appeal to Hindu authorities and the most obvious names listed in this regard are Madhusudan Gupta – celebrated as the first Indian to dissect a cadaver (though recent histories have justifiably questioned this claim) – and Kamalakantha Vidyalanka, who was appointed teacher of Rhetoric at the Sanksrit College and became part of the British judicial system as a pundit.

Vidyalanka appears to have had no direct link with medicine but provides O’Shaughnessy with a number of obscure Sanskrit references to the use of hemp, including a prohibition for Brahmins in particular found in the texts of Manu.

While reaching out to his scholarly friends on the one hand, O’Shaughnessy also sought advice from the Deputy Superintendent of Police, Mr McCann, on official surveys regarding the consumption of “gunjah”. But if he wanted to know about the daily lives of his consumers, he needed someone “irregular”. For such purposes he tapped into the experience of one Ameer, “the proprietor of a celebrated place of resort for Hemp devotees in Calcutta, and who is considered the best artist in his profession.” For understandable reasons, that is all we ever learn regarding the identity of Ameer.

It is perhaps thanks to Ameer, that O’Shaughnessy’s report is so able to display an exceptionally close knowledge of the uses of the various extracts. While Sidhee, Subjee and Bang (“used with water as a drink”) is “chiefly used by the Mahomedans of the better classes”, Sidhee (“ground, mixed with black pepper, and a quart of cold water”) is the “favourite beverage of the Hindus who practice this vice”. Gunjah, on the other hand, is “used for smoking alone”, and one rupee weight mixed with dried tobacco, “suffices for three persons”, although you find “four or five persons usually join in the debauch”. The demography is curious, especially in the case of Majoon, (a hemp confection which is “a compound of sugar, butter, flour, milk, and Sidhee or Bang”) which is consumed by all classes, “including the lower Portuguese or ‘Kala Feringhees,’ and especially their females”.

For interested parties let it be known, O’Shaughnessy has provided ample details to try out your own nineteenth-century recipes. He distinguishes between each type of extract and offers specific descriptions of how they are prepared, although the one which he recommends in greatest detail is meant for medicinal use only. Inadvertently he also maps availability of the finest quality of each kind — sourcing his churrus as he did from Nepal, thanks to Dr. A. Campbell of the Bengal Medical Service, a man with the dubious distinction of changing the course of Darjeeling’s history when as Superintendent he oversaw a huge population rise between 1839 and 1849. The first part of the article also offers a rare glimpse into the contemporary consumption habits — an account that differs in tone and content from the usual official surveys.

If we discard the binary model often used to understand the exchange of knowledge (scientific, legal, or otherwise) between the colonial centres and peripheries, and turn to the idea of networks (as the historian Kapil Raj, for instance, has done), we realize that the networks that produce knowledge are much more complex than they appear at first glance. In W. B. O’Shaughnessy we have someone who is rigorous in noting down all the different sources of information that he taps into, and we realize that, upon closer inspection, even the nodes of a network give way to many other interconnected webs.

In the thirty-one-page Report on the Investigation of Cases of Real and Supposed Poisoning (1841), found in the National Library of India (Kolkata), we see our doctor sitting in the centre of another web of intrigue. After a call out, people sent O’Shaughnessy items ranging from “the remains of a chapattee, which is said to have been the cause of death of Dasi Bania” to “a stomach…and the small intestines with the contents thereof, all stated to have been removed from the body of a man” found dead in the Native Hospital.

O’Shaughnessy, who was Chemical Examiner to the Government, received mails from persons in different posts in the British government from all over Bengal. He would send back his reports with details of his chemical analysis, opining whether there may have been foul play. He often struggled with forms of poison (often with the common bish which is available at any Calcutta market) that were not yet recognized by Western medicine.

Table from O’Shaughnessy’s Report On The Investigation Of Cases Of Real And Supposed Poisoning (1841). Credit: Report on the investigation of cases of real and supposed poisoning.

O’Shaughnessy’s language seems to anticipate at times the medico-forensic phrasings of Conan Doyle’s Dr. Watson. He begins Case 12 thus:

These are by far the most interesting cases which I have ever met with. The respectability of the individuals implicated; the extraordinary period which elapsed during which the bodies were exposed, without coffins, to the destroying influences of the heat and rains of Bengal; the curious changes which the poison underwent…constitute an array of circumstances scarcely surpassed in medico-legal interest by any but those of the celebrated Laffarge trial.

This was not his first encounter with the science of criminal activity. In 1830, a young O’Shaughnessy arrived in London, struggling to find permanent employment. Soon after, urged by the editor of The Lancet, he published an article on “Poisoned Confectionary”, the result of an extensive study. Along with a Dr. Green, he purchased “at several shops, different specimens of coloured confectionary, and of colourless articles wrapped in stained paper.” Each colour was analyzed rigorously. The yellow, for instance, was understood to be a result of adulterating the candies with either “gamboges, massicot, Naples yellow, the chromate of lead, or vegetable lakes.” A report on the study was published in an 1831 issue of The Medico-chirurgical Review and Journal of Practical Medicine, in which the writer remarks: “Dr. O’Shaughnessy is evidently a clever chemist, and his industry appears equal to his talent in the department of human knowledge”.

The Journal of the Asiatic Society of Bengal published in the span of a few months two other experiments performed by O’Shaughnessy. In 1839 he reports on his use of the Galvanic battery for the “successful destruction of the wreck of the Equitable at Fultah Reach”, where the Sydney-bound ship “leaden with wheat, rice, rum, &c.,” had touched on the sand below and turned over “in six to seven fathoms of water”. The first one, however, anticipates his later work on telegraphy — a form of communication that would be taken seriously only after 1847, with Lord Dalhousie’s appointment as governor general.

At the Botanical Gardens in Shibpur (he already had cordial relations with the persons in charge, such as Nathaniel Wallich), he experimented with the first telegraph circuit. After laying the cables, the two ends starting and ending where he positioned himself, he used to a pair of modified watches “of the cheapest kind”. (This is before his visit to England where he learnt of the Morse.) “Round the second hand was placed a card dial laid off with three concentric circles divided each into twenty parts.” He omitted “vowels and superfluous letters” (reminiscent of today’s SMS truncations), and using this he successfully sent across messages. Each signal took about three minutes to transmit, and both watches were “then allowed to run to No. 1 or zero, and stopped”.

It is in his work on the telegraph system – and particularly his role in rebuilding it after it was largely destroyed in the Indian Rebellion of 1857 – that we can see more clearly the dubious nexus between such scientific projects and the endeavours of colonialism, a connection made more explicit at moments of political crisis. As far as O’Shaughnessy’s contribution to medicine is concerned, its correlation with colonial power is perhaps not as obvious. Yet it does contribute, even if unintentionally to the larger discourse of knowledge/power, relating to what Shiv Visvanathan and Ashis Nandy call the “industrial grid”.

Western medicine, through sheer claim of objectivity, marginalised, traditional, and subsequently, “folk medicine”, while at the same time deriving its legitimacy on foreign soil from references to indigenous texts and social practices, through Sanskrit and Perso-Arabic scholars and local practitioners. In this regard O’Shaughnessy was no exception. Rather than thinking only of centres (individual or institutional) of knowledge production in the colonies, we’d do better than to focus more on the complexity of networks and exchanges – the go-betweens, as Kapil Raj calls them – who played such a key role in the production of the colonial sciences. It is here, in light of such an approach, that the detailed notes left behind by William Brooke O’Shaughnessy prove so invaluable, offering a rare and honest glimpse into how such networks functioned.

Students innovate wheelchair that climbs stairs, med box with alert

Kolkata :

A wheelchair that can climb stairs, a medicine dispenser that sends out reminders to users, and a walking stick that helps people with visual impairment mavigate with the help of audio messages. These were among 30 innovations that students at 24 institutions in eastern India demonstrated at a CII meet on innovation and startups in the city.

Conscious of the difficulty that the elderly and infirm experience in climbing stairs, students at JIS College of Engineering presented a wheelchair designed to climb stairs, with the help of three sets of wheels that work in tandem. Another innovation was Urja, a multi-purpose electric source, presented by Anish Kumar Sarangi from Silicon Institute of Technology, Bhubaneswar. The device can be used as a portable power source, a high-frequency mosquito repellent, a passive water filter, an LED light and a USB port, from which mobiles can be charged or USB fans can be operated. “Nearly two out of every 10 people in Asia and almost 300 million people in India do not have access to electricity. The challenge is to bring power to them.” Sarangi said.

“CII has formed innovation clubs at different colleges. Commercially viable projects are selected by the jury. Those projects, along with their prototypes, are displayed and some of them adapted in industries. We focus on four main fields: agriculture, education, finance and health,” said Dipankar Chakrabarti, co-chairman, CII Eastern Region Startup & Innovation Taskforce.

Students at Sudhir Chandra Sur Degree Engineering College have created an automatic medicine dispenser for which an app has been developed. Once the medicine schedules are fed into the dispenser the machine can deliver tablets or syrup at the correct time.

Among the other innovations was a solar AC proposed by Narula Institute of Technology. Its students have also proposed smart gloves that can translate gestures into speech to facilitate easier communication by people with speech impairment.

Jadavpur University students have proposed a light, portable, durable and fire-proof cabin that can be used by armed forces at the border.

MCKV Institute of Engineering presented a walking stick and a safety app that gets triggered when a ring worn by the user comes in contact with the mobile. The stick is fitted with GPS and guides the user —a visually impaired person—with audio directions.

Software Technology Parks of India additional director and officer in-charge Manjit Nayak felt most proposals had the potential to be developed into products. “A Class XII student from Bihar came up with a wireless device with which one can remotely control a tractor,” he said.

Students unite over water of the world

Chowringhee:

A study on quality of water brought together schoolchildren from Calcutta and Kentucky.

Students of 10 schools from Calcutta, Durgapur, Kharagpur, Ranchi and Guwahati studied the quality of water from various sources and the Kentucky students assessed the impact of coal mines on water. They presented their projects at American Center on Friday.

Ten schools from eastern India and 12 from Kentucky tested samples from 121 water bodies, including rivers, wetlands, ditches, canals, wells and ponds in their own areas. The findings were shared with the community to discourage contamination of water.

The project titled Exploring Water Quality in Eastern India and Kentucky was launched by the US consulate general in Calcutta, in collaboration with University of Kentucky and Association of Social and Environmental Development,

“We hope the participants will take the lead in championing positive social change regarding water quality and conservation,” said Jamie Dragon, director, American Center.

The students of Belfry High School investigated water in 10 wells near coal mines.

“We will present a proposal to the Environmental Protection Agency in the US because well water is not regulated,” said Haridas Chandran, physics teacher at Belfry.

The students of DAV Model School, Durgapur, checked the pH level of Barakar river water and its residual chlorine content. One of the findings was that storing the water for long is not recommended because the absence of residual chlorine can trigger a significant growth of microbes.

“We carried out some tests in the school laboratory and the rest on river banks,” said Soumit Das, Class XII.

Garden High School worked on wetlands and Sri Sri Academy on water quality of Hooghly.

Carol Hanley, who guided the students in India and Kentucky, said they had to choose a waterbody that had both cultural and scientific significance.

“We call this community- based science so that science becomes real,” said Hanley, the director, College of Architecture, Food and Environment, University of Kentucky.

Software developed by N Bengal techie helps check Oz shark attacks

Shark Spotter has been deployed in 11 beaches in north New South Wales such as Byron Bay, Ballina (picture for representation only)

Jalpaiguri :

Remember Jaws, the 1975 Hollywood thriller on a giant man-eating great white shark that struck terror on fictional resort town Amity Island? In beaches across Australia, the Steven Spielberg reel horror is real with the country recording the largest number of unprovoked shark encounters with humans after the United States.

Now several Australian beaches have deployed a technology co-developed by a technologist from north Bengal that uses artificial intelligence to seek out sharks based on aerial footage from drones and warn swimmers to get out of the water quickly.

Dubbed as Shark Spotter, the software uses an algorithm capable of using video footage streamed from drones to detect sharks and alert swimmers. “The Shark Spotter is the world’s first, non-destructive technology able to detect sharks and other potential threats using real-time aerial video imagery. The new algorithm is 90% accurate in distinguishing sharks from other marine life. Human spotters from fixedwing aircraft or helicopter have accuracy of 12%-18%,” said Nabin Sharma, a lecturer at the University of Technology Sydney, who along with Michael Blumenstein developed the software that is making waves Down Under.

Shark Spotter has been deployed in 11 beaches in north New South Wales such as Byron Bay, Ballina, where shark attack was a major problem. And they have already saved lives. Shark attack reports from these beaches have declined significantly, prompting authorities in beach towns in the US and Europe to also consider the technology.

The Shark Spotter technology has won in three major categories (Research & Development Project of the year, Artificial Intelligence or Machine Learning Innovation of the year and Community Service Markets) in the Australia Information Industry Association, iAward 2018, New South Wales.

Sharma did his schooling in Holy Child School, Jalpaiguri, before graduating from Ananda Chandra College in the town. He then did Master of Computer Application (MCA) and Bachelor of Science from Siliguri Institute of Technology, before doing his PhD from the School of ICT, Griffith University. He is currently a lecturer with the School of Software, University of Technology Sydney (UTS).

Of more than 500 known shark species, 26 have been involved in unprovoked attacks on humans. Of these, Australia has 22 shark species. Australia records an average 1.5 deaths per year from shark .

TCS is largest employer in Bengal

Calcutta:

TCS has emerged as the largest employer in the private sector in Bengal, having close to 40,000 people on the rolls spread across 15 locations in Calcutta.

The company, India’s largest by market capitalisation, has added 10,000 people in the last 33 months alone. It is expected to add another 2,000 this year .

Even as automation, digital disruption and just-in-time recruitment may potentially tamper the pace of addition of workforce across the company, TCS executives said Calcutta will continue to maintain its share of the overall pie.

The company has close to 3,95,000 people on the rolls as on March 31, 2018 across 50 countries, but mostly in India.

Ajoyendra Mukherjee, executive vice-president and global head of human resources of TCS, said the company has given 20,000 offer letters to students in campuses across the India.

In Bengal, the company has gone to 40 engineering colleges last year, offering employment to nearly 2,000 students. Apart from TCS, Bandhan Bank, RP-SG Group and ITC are some of the large private sector employers in the state.

The special economic zone in Rajarhat now houses the largest facility for TCS in the city. It employs around 17,000 people, operating at 90 per cent of the capacity.

The IT behemoth has 2.5 million square feet space in this 40 acre sprawling campus, out of the 4 million square feet it has across Calcutta, including leased and owned space. The city is one among the top four locations for TCS in India.

The campus still has the space to add at least one million square feet and create at least 10,000 more jobs.

According to Suresh G Menon, vice president and general manager – eastern region of TCS, banking financial, utilities, retail are some of the core areas Calcutta focuses on. “We are 10 per cent of TCS now,” he said.

Tapering curve

Mukherjee said the company’s headcount would not grow at the same pace as revenue like in the past, due to multiple factors, such as automation in the IT world and cost push. The company recorded 7,700 net addition last year.

“Analytics, IoT (Internet of Things) and automation are changing the entire delivery process. We are going for hiring in an agile way which is on-demand,” Mukherjee explained.

IIT robot goes the distance

Robot-driven vehicle, Eklavya

Kharagpur:

A robot-driven vehicle called Eklavya won IIT Kharagpur the runner-up position in the Intelligent Ground Vehicle Competition at Oakland University in Rochester, Michigan, recently.

The robots were ranked according to the distance they covered in the designated arena while keeping to the lanes given by GPS coordinates, all the while avoiding obstacles on the way.

Eklavya, designed by the Kharagpur institute’s autonomous ground vehicle (AGV) team, covered 260 feet, said an official of the institute.

The AGV team is a multidisciplinary research group.

“For prototype purposes, we work on Eklavya which is a three-wheeled, front-driven and front-steered electric vehicle fitted with cluster wheels,” an official of the institute said.

Work for building the robot started in December last year under the supervision of Debasish Chakravarty, a professor of mining engineering at IIT Kharagpur.

“Students were required to work on image perception, simultaneous localisation and mapping, path planning algorithm, mechanical design and electronic design to come up with the robot-driven vehicle,” Chakravarty said.

Rahul Krantikiran, one of the five members of the participating team, said they were asked to cover a distance of 600 feet.

“We covered a distance of 260 feet. Though the time was not specified, I think we took around 2.5 minutes to 3.2 minutes to cover the distance. The only team that could outperform us was the team from CART (Center for Applied Research and Technology), Inc. from Bluefield State College, US,” said the student of computer science and engineering.

The team is exploring whether Eklavya can be fitted to an existing fuel-run vehicle.

“It requires advanced research. If it can be fitted to fuel-driven car, it will gain popularity,” Chakravarty said.

Seven teams from India, including ones from IIT Kanpur and IIT Madras, took part in the competition held from June 1 to 4.
