NATIONAL: Kolkata’s First Underwater Metro starts its trial run below bed of Hooghly

Tunnels under the bed of river Hooghly, running 32 metres below water level, are considered an engineering marvel; Metro station at Howrah too is deepest in the country; commercial services on the stretch expected to begin later this year .

Kolkata Metro on Wednesday achieved a new milestone when a Metro rake completed a journey under the bed of river Hooghly through a tunnel 32 metres below water level.  

“P. Uday Kumar Reddy, General Manager, Metro Railway, travelled from Mahakaran to Howrah Maidan station in Rake No. MR-612 to witness this historic event. This rake crossed river Hooghly at 11:55 hrs. H.N. Jaiswal Additional General Manager, Metro Railway and MD, KMRCL [Kolkata Metro Railway Corporation Limited] as well as other senior officers of Metro Railway and KMRCL accompanied him during this journey,” a press statement by Metro Railway, Kolkata said. General Manager Reddy offered puja at Howrah station once the Metro rake reached there, the statement added.

Describing the development as a “historic event’ Mr. Reddy informed that the trial runs from Howrah Maidan to Esplanade will be conducted for the next seven months and after that regular services on this stretch will begin. It is expected that commercial services on this stretch will begin this year. 

Two Metro rakes had been taken to Howrah Maidan station from Esplanade station, for the trial runs along the 4.8-km underground section from Howrah Maidan to Esplanade. Tunnels under the bed of river Hooghly, 32 metres below the water level, are considered an engineering marvel and are part of East West Metro Project that aims to connect Howrah Maidan with Rajarhat along the 16.6-km route. The process of laying the tunnel was completed in 2017. The underwater tunnels will connect Kolkata and Howrah with a Metro station at Howrah which will be the deepest Metro station (33 metres below surface) of the country. The Metro is expected to cover the 520-metre stretch under the river Hooghly in a span of 45 seconds.

At present about 9.1 km of the East West Metro line from Salt Lake Sector V to Sealdah is operational. Services of East West Metro Railway was started in phases with first phase in February 2020 and the latest in July 2022.

INTERNATIONAL: SPACE /SCIENCE & TECHNOLOGY: 11 Teams to Represent India at the ‘NASA Human Exploration Rover Challenge 2023’ in the U.S this month.

At the NASA Rover Challenge 2023 these teams will compete against 61 others selected worldwide for the 3-day contest to be held from April 20-22.

11 Indian teams including three high school groups will participate in the prestigious ‘NASA Human Exploration Rover Challenge’ (HERC) 2023 in the  United States this month. These teams are among 61 others worldwide that will represent India at the international level and will travel to the American agency’s space & rocket centre in Huntsville, Alabama, US to take part in the three day competition from April 20-22.

The HERC Challenge demands teams to design, develop, build, and test human-powered rovers capable of traversing challenging terrain and a task tool for completion of various mission tasks, NASA explained, giving an overview about the competition.

The list of Indian teams participating this year:

Amity University, Noida, Uttar PradeshCollege/University
Birla Institute of Technology and Science, Pilani, Pilani, RajasthanCollege/University
Hindustan Institute of Technology and Science, Chennai, Tamil NaduCollege/University
KIET Group of Institutions, Ghaziabad, Uttar PradeshCollege/University
Prayatna Charitable Trust, Ahmedabad, GujaratHigh School
Punjab Engineering College, Chandigarh, PunjabCollege/University
Shiv Nadar University, Gautam Buddha Nagar, Uttar PradeshCollege/University
Tec Mantra Labs, Kurukshetra, HaryanaHigh School
Vellore Institute of Technology, Chennai, Tamil NaduCollege/University
Vellore Institute of Technology, Vellore, Tamil NaduCollege/University
Young Tinker Educational Foundation, Bhubaneswar, OdishaHigh School

Of these, VIT, Vellore, Chennai, HITS, Chennai, BITS Pilani, Rajasthan and Amity Noida, KIET Group of Institutions, Uttar Pradesh featured in the 2022 challenge as well.

Releasing a list of selected teams in October last year(full list here), NASA announced that these teams would be judged based on their ability to design and assemble a rover to traverse a course of approximately half-mile that includes 10 obstacles and 5 tasks with a simulated field of asteroid debris, boulders, erosion ruts, crevasses, and an ancient streambed. “As part of the competition, rover entries are tested to ensure they would fit into a lander storage area, a maximum 5 feet long by 5 feet tall by 5 feet in volume,” NASA said.

The weight and time criteria encourages teams to build their vehicles around its compactness, light weight, high performance, and efficiency. Teams must make real-time decisions on mission objectives – what to attempt or leave behind, driven by limited virtual oxygen supply lasting 8 minutes. The teams earn points on successful completion of these tasks and the one with the highest number of points throughout the project wins the game in each category (high school/college and universities).

Even though Indian teams did not win the overall prize in either category last year, the students are hopeful for international recognition with larger participation this year.

Akanksha Das, a member of one of the participating teams, Young Tinker Educational Foundation, expressing her enthusiasm about the contest, told news agency ANI, “…We sent a proposal to Nasa and they accepted our proposal and we followed all the guidelines. We created a lightweight Rover. In the last edition we got world rank 3, this year we hope to bring 1st position in world rank.”

INTERNATIONAL AWARD : STATISTICS : Indian-American Calyampudi Radhakrishna Rao (C.R. Rao) Wins Top Statistics Award, the ‘ 2023 International Prize in Statistics ‘ – a look back at his pioneering work

Indian-American statistician Calyampudi Radhakrishna Rao has been awarded statistics’ equivalent of the Nobel Prize.

The Indian-American statistician Calyampudi Radhakrishna Rao has been awarded the 2023 International Prize in Statistics, which is statistics’ equivalent of the Nobel Prize. It was established in 2016 and is awarded once every two years to an individual or team “for major achievements using statistics to advance science, technology and human welfare.”

Prof. Rao, who is now 102 years old, is a ‘living legend’ whose work has influenced, in the words of the American Statistical Association, “not just statistics” but also “economics, genetics, anthropology, geology, national planning, demography, biometry, and medicine”. The citation for his new award reads: “C.R. Rao, a professor whose work more than 75 years ago continues to exert a profound influence on science, has been awarded the 2023 International Prize in Statistics.”

What was Rao’s 1945 paper about?

Rao’s groundbreaking paper, ‘Information and accuracy attainable in the estimation of statistical parameters’, was published in 1945 in the Bulletin of the Calcutta Mathematical Society, a journal that is otherwise not well known to the statistics community. The paper was subsequently included in the book Breakthroughs in Statistics, 1890-1990.

This was an impressive achievement given Rao was only 25 at the time and had just completed his master’s degree in statistics two years prior.

He would go on to do his PhD in 1946-1948 at King’s College, Cambridge University, under the supervision of Ronald A. Fisher , widely regarded as the father of modern statistics.

The Cramér-Rao inequality is the first of the three results of the 1945 paper. When we are estimating the unknown value of a parameter, we must be aware of the estimator’s margin of error. Rao’s work provided a lower limit on the variance of an unbiased estimate for a finite sample. The result has since become a cornerstone of mathematical statistics; researchers have extended it in many different ways, with applications even in quantum physics, signal processing, spectroscopy, radar systems, multiple-image radiography, risk analysis, and probability theory, among other fields.

In an article published in the journal Statistical Science in 1987, the American statistician Morris H. DeGroot set out an intriguing story (corroborated by Rao’s own account) of how Rao arrived at the lower limit. Prof. Fisher had already established an asymptotic (i.e. when the sample size is very large) version of the inequality, and it seems a student had asked Rao, “Why don’t you prove it for finite samples?” in 1944. A then-24-year-old Rao did so in under 24 hours!

The second outcome of the 1945 paper was the Rao-Blackwell Theorem, which offers a method to improve an estimate to an optimal estimate. The Rao-Blackwell theorem and the Cramér-Rao inequality are both related to the quality of estimators.

A new interdisciplinary area called ‘information geometry’ was born as a result of the paper’s third finding. This field integrated principles from differential geometry into statistics, including the concepts of metric, distance, and measure. Erich L. Lehmann, a renowned statistician, said in 2008 that “this work [of Rao’s] was before its time and came into its own only in the 1980s”.

So overall, Rao’s 1945 paper made an outstanding contribution, boosting the development of modern statistics and its widespread application in modern research. In a 2008 book, Reminiscences of a Statistician: The Company I Kept, Lehmann also discussed the generative nature of the paper – i.e. the goldmine of insights that it was – and acknowledged that “several of my early papers grew out of Rao’s paper of 1945”.

How did Rao enter the field of statistics?

The Australian statistician Terry Speed claimed that the “1940s were ungrudgingly C.R. Rao’s. His 1945 paper … will guarantee that, even had he done nothing else – but there was much else.”

Indeed, one of Rao’s papers in 1948 offered a novel generic approach to testing hypotheses, now widely known as the “Rao score test”. In fact, the three test procedures – the likelihood ratio test of Jerzy Neyman and E.S. Pearson (1928), the Wald test (1943) of Abraham Wald, and the Rao score test (1948) – are sometimes called “the holy trinity” of this branch of statistics.

Rao also contributed to orthogonal arrays, a concept in combinatorics that is used to design experiments whose results are qualitatively good, as early as 1949. A 1969 Forbes article described it as “a new mantra” in industrial establishments.

Given the magnitude and relevance of his contributions, it might seem surprising that Rao entered the field of statistics by chance.

Despite scoring first in mathematics at Andhra University, a 19-year-old Rao didn’t secure a scholarship there for administrative reasons. He was also rejected for a mathematician’s job at an army survey unit because he was judged to be too young.

When he was staying at a hotel in Calcutta, he met a man who was employed in Bombay and had been sent to Calcutta to be trained at the Indian Statistical Institute. He asked Rao to apply to the institute as well. Rao did so, for a year-long training programme in statistics, hoping the additional qualification would help him land a job.

P.C. Mahalanobis, then director of the institute, replied promptly and Rao was enrolled. That marked the beginning of a four-decade-long stay at the institute. Rao retired in 1979 and afterwards settled in the U.S.

The first half of the 20th century was the golden period of statistical theory in general, and Rao is undoubtedly one of the reasons for this being the case, thanks to his mathematical ingenuity. In the words of the late mathematician Samuel Karlin, Rao’s contributions to statistical theory have “earned him a place in the history of statistics”.

Indian statisticians also owe Prof. Rao gratitude for his enormous contributions to the growth of statistics in the country, notably at the Indian Statistical Institute (where this author works). As Lehmann wrote, Rao was “the person who did the most to continue Mahalanobis’s work as a leader of statistics in India.”

GLOBAL: ECONOMY: India, China to Account for Half of Global Economic Growth in 2023: International Monetary Fund (IMF)

The period of slower economic activity will be prolonged, with the next five years witnessing less than 3 per cent growth.

The IMF chief on Thursday said that the world economy is expected to grow at less than 3 per cent this year, with India and China expected to account for half of global growth in 2023.

International Monetary Fund (IMF) managing director Kristalina Georgieva warned that a sharp slowdown in the world economy last year following the raging pandemic and Russia’s military invasion of Ukraine would continue this year.

The period of slower economic activity will be prolonged, with the next five years witnessing less than 3 per cent growth, “our lowest medium-term growth forecast since 1990, and well below the average of 3.8 per cent from the past two decades,” she said.

“Some momentum comes from emerging economies — Asia especially is a bright spot. India and China are expected to account for half of global growth in 2023. But others face a steeper climb,” she explained.

“After a strong recovery in 2021 came the severe shock of Russia’s war in Ukraine and its wide-ranging consequences — global growth in 2022 dropped by almost half, from 6.1 to 3.4 per cent,” Georgieva said.

Georgieva said slower growth would be a “severe blow,” making it even harder for low-income nations to catch up.

“Poverty and hunger could further increase, a dangerous trend that was started by the COVID crisis,” she explained.

Her comments come ahead of next week’s spring meetings of the IMF and the World Bank, where policy-makers will convene to discuss the global economy’s most pressing issues.

The annual gathering will take place as central banks around the world continue to raise interest rates to tame galloping inflation rates.

About 90 per cent of advanced economies are projected to see a decline in their growth rates this year, she said.

For low-income countries, higher borrowing costs come at a time of weakening demand for their exports, she said.

Georgieva added that while the global banking system had “come a long way” since the 2008 financial crisis, “concerns remain about vulnerabilities that may be hidden, not just at banks but also non-banks.

“Now is not the time for complacency.”

NATIONAL: TRANSPORT / RAILWAYS: The 150-year-old Chennai Central becomes India’s First ‘Silent’ Railway Station

Taking a cue from airports, the station is trading the omnipresent ‘voice’ for more inquiry booths and visual display boards.  

The 150-year-old Dr MGR Ramachandran Central railway station in Chennai went silent on Sunday, making it the first in India to do so, as it bid adieu to the public announcement system that has guided passengers to their trains for decades. Taking a cue from airports, the station is trading the omnipresent ‘voice’ for more inquiry booths and visual display boards.  

In the order announcing the change, issued on Saturday by Southern railway general manager R N Singh, officials were told to ensure all visual display boards are in working condition and to deploy sufficient staff at inquiry booths for a smooth passenger experience.

Large digital screens displaying the arrival and departure of trains in Tamil, Hindi and English have been installed at all three entry points to the station, namely, EVR Periyar Salai (MTC bus stop), suburban terminus, and Wall Tax Road (gate no 5). Concourse areas have also been covered with 40-60 inch digital boards.
