  • Unhygienic Sabarmati water forces triathlon to indoor pool

    Triathletes on the thirty sixth National Games had been to swim within the Sabarmati River to compete for over 750 metres in open waters, along with biking 20 kilometres and working 5km. But they are going to now swim throughout the confines of an Olympic-size pool — 50 metres in size — on the Indian Institute of Technology, Gandhinagar as a substitute.

    The purpose: the green-coloured water of the Sabarmati river, described by organisers as ‘unhygienic and infectious’ that would end in swimmers getting infections.

    Since July, when the Indian Olympic Association (IOA) introduced Gujarat because the host of the National Games, Amdavad Municipal Corporation officers had performed a number of exams to verify the standard of the Sabarmati water.

    “The results showed the quality of water wasn’t nice at all. And since the water is very polluted, it was suggested the event should not be held here,” Virendra Nanavati, the vice-president of the Gujarat State Olympic Association, advised The Indian Express. “We argued that in rowing (the other sport that’s being held at the venue), they put boats in the water and people don’t come directly in contact with it. That’s not the case in swimming and we’d risk infecting people if they swam in the water.”

    Nanavati added that as drainage water is launched into the river, it made the venue unsuitable. “We hoped that it would get better once the monsoon began, assuming that the water will get washed and cleaned. But nothing really happened,” Nanavati, additionally a veteran swimming administrator, stated.

    Hence, on the final second, the triathlon venue was moved to Gandhinagar.

    The triathlon consists of three segments: 750m swim, 20km biking and 5km street race.

    According to triathlon competitors supervisor Harish Prasad, the water high quality check is carried out routinely and a last check is completed roughly a fortnight earlier than the beginning of the occasion. The water, he stated, “need not be consumable but it should not harm the athlete”.

    Ahmedabad’s riverfront had emerged as a really perfect location to host the triathlon as a result of it additionally has an ideal promenade to transition from one phase of the race to a different and is in shut proximity to roads that can be utilized for biking and working.

    Porbandar, which held a triathlon nationwide championship again in 2007, emerged as an alternate. However, conducting the races there would have posed the organisers with the logistical drawback of accommodating a whole lot of individuals in a small metropolis. It would even have meant increasing the Games to seven cities — from six — which might’ve been one other hurdle.

    Other areas weren’t thought-about, in response to a Sports Authority of Gujarat official, due to the state authorities’s crocodile conservation venture. Many rivers and lakes throughout Gujarat, the official stated, are infested with the reptile, making it unsafe to conduct swimming races there. And even when there have been crocodile-free venues, an excellent street for biking wasn’t simply accessible from the water physique.

    It reached a degree in early September the place the game was nearly dropped from the Games programme.

    A special problem

    While it’s not unprecedented to carry triathlon swimming races in a swimming pool, it’s unusual since all prime races are held in open waters, together with on the Olympic Games.

    From October 9 to 11, a complete of 32 males from 23 states and 30 ladies from 16 states will compete within the triathlon on the National Games. Two athletes will occupy one lane and leap into the pool in two waves to keep away from congestion. Each must swim 15 laps of the pool.

    Pratap Mohan, father and coach of certainly one of India’s prime triathletes Pragnya, stated swimming in open waters is rather a lot harder. “In open water, the swimmer has to find his or her own line to swim, making it that much more challenging,” Mohan stated. “And in a pool, you also get a push from the wall every 50m, which adds to the speed.”

    The problem to conduct this occasion, nevertheless, didn’t finish with the provision of fresh water. The street outdoors the IIT campus, the place the organisers hoped to conduct the biking race, was uneven and bumpy, making it dangerous to carry the race.

    However, inside 10 days, the stretch of roughly 5km was relaid by the town administration. “In a short span, with the help of everyone, we could get everything in place, including the relaying of the road just outside the campus for the cycling race. That will eventually help the people who live here,” Prasad stated.

  • C-DAC, IIT Gandhinagar unveil Param Ananta, India’s newest supercomputer

    The Centre for Development of Advanced Computing (C-DAC) and the Indian Institute of Technology, Gandhinagar have collectively unveiled a brand new supercomputer in part two of the central authorities’s National Supercomputing Mission (NSM). Called Param Ananta, the supercomputer is able to providing peak efficiency of 838 teraflops.

    Sanctioned in October 2020, Param Ananta will provide IIT Gandhinagar with elevated capability for analysis initiatives in numerous fields, together with machine studying, information science, computational fluid dynamics, bioengineering and extra.

    According to a press release by the Ministry of Electronics and Information Technology (Meity), the supercomputer has a blended set of CPU and GPU nodes, together with excessive throughput storage and excessive bandwidth reminiscence modules. It can be stated to supply direct contact liquid cooling expertise to extend efficiency effectivity, though it isn’t clear as to what efficiency per watt does it provide.

    The supercomputer will rank behind C-DAC’s Param Siddhi-AI, which as of November 2021 was the 102nd strongest supercomputer on the earth — with peak efficiency functionality of three.3 petaflops.

    With Param Ananta, India now has 15 supercomputers disclosed to the general public, with mixed efficiency functionality of 24 petaflops.

    The announcement curiously comes on the identical day when USA’s Frontier supercomputer, run by the Oak Ridge Leadership Computing Facility, was formally ranked as essentially the most highly effective supercomputer on the earth. The latter outperformed Fugaku, now the second strongest supercomputer and operated by Japan’s Riken Centre for Computational Science, to take the highest spot.

    Frontier has been labelled because the world’s first ‘true’ exascale supercomputer, able to producing total computing energy in a number of exaflops. In direct comparability, C-DAC and IIT Gandhinagar’s newest Param Ananta supercomputer gives a fraction of the online efficiency functionality that the world’s strongest publicly recognized supercomputer can produce at present.

    The official checklist of the world’s high 500 supercomputers shall be printed in Hamburg, Germany on June 1.

  • IIT Gandhinagar develops framework to cut back injury to energy transmission programs throughout cyclones

    By PTI

    NEW DELHI: Researchers on the Indian Institute of Technology (IIT), Gandhinagar, have developed a complete framework that may scale back the injury to energy transmission programs in coastal areas below cyclone situations.

    The workforce used damage-cum-wind pace information of Cyclone Fani in Odisha to develop a fragility mannequin for towers, which helps assess the performance of the community and the affect of strategic interventions on the identical.

    According to the workforce, they discovered that essentially the most environment friendly technique may very well be to choose a fraction of towers from the very best wind pace zones (in line with the Indian requirements) which might be related to substations serving a big inhabitants.

    Strengthening towers nearest to the coast might considerably assist scale back the variety of towers broken throughout a cyclone, however its resultant influence on the affected inhabitants will not be as vital.

    The examine outcomes revealed {that a} larger variety of strengthened towers or a larger degree of strengthening in them based mostly on tailored and environment friendly reinforcement prioritisation methods in a selected area results in higher performance of energy transmission programs.

    The analysis workforce additionally discovered that strengthening the towers in a transmission line related to necessary substations (significance was quantified by way of inhabitants served by the substation) near the shoreline led to most enhancement in efficiency, which means lesser inhabitants is affected, they claimed.

    “This is a first of its kind research work because here we were able to consider a large-scale network, its relationship with the coastline, a suitable context-specific fragility curve for the towers, and realistic cyclone scenarios in a reasonable manner, which led to interesting insights into strengthening strategies for the power transmission network of Odisha. The framework can be useful for cost-effective strengthening of transmission tower networks of other coastal states of India as well, such as West Bengal, Andhra Pradesh, Tamil Nadu, Gujarat, and Maharashtra,” stated, Manish Kumar, Associate Professor at IIT Gandhinagar.

    “The towers can be prioritised differently if a different performance metric is selected. Structural strengthening that would lead to the shift in the fragility curves considered in this study can be based on wind-tunnel tests and/or computational fluid dynamics analyses, which will further optimise the resources. This approach may also be relevant for transmission lines associated with some power plants that may require a shutdown in the event of damage to the lines,” he added.

    The researchers noticed that the loss in performance of transmission towers relies upon significantly on the situation of the landfall of the cyclone.

    The injury was larger if the landfall was near a area with many substations within the neighborhood.

    This remark emphasises the necessity to think about the orientation of the community with respect to the shoreline and the practical properties of cyclones.

    Researchers additionally famous that the lack of performance in energy transmission may very well be affected significantly by the trail of a cyclone earlier than making landfall.

    “A simulated cyclone trajectory indicated that it could damage towers even up to 300 km apart from each other, which further underscores the need to perform such studies on a holistic scale. The framework developed by the team helps in prioritising the towers that should be strengthened to minimise the overall losses in functionality in a cost-effective manner,” he stated.

    The workforce thought of two broad facets to determine towers for precedence strengthening which have been identification of a geographical area and foundation for prioritisation inside that geographical area.

    Each intervention recommended by the workforce is exclusive from one another by way of number of a geographical area, the premise for prioritising the towers, the variety of towers to strengthen, and the extent of strengthening thought of.

    “In post-disaster scenarios, decision-makers always face a constraint on 3Ms, i.e. Manpower, Money (budget), and Materials. Hence, there is a need to supplement the bird-eye view with the component level view to identify the right set of components that should be reinforced and strengthened to minimise damage after natural calamities,” stated Udit Bhatia, Assistant Professor of Civil Engineering at IITGN.

    “Changing climate scenarios and upward trend in frequency and magnitudes of cyclones as a consequence of increasing Sea Surface Temperature put our coastal infrastructure at a greater risk. While our understanding of these hazards has increased significantly in recent years, still a lot needs to be done on the adaptation side. Our framework brings us one step closer to possible solutions that stakeholders and infrastructure managers can invest in,” added Bhatia.
