IIT-BHU study validates fairness of Random Number Generators in online card games
The team used the globally recognised 'Dieharder' statistical test suite, a benchmark for RNG quality, to assess thousands of card distribution sequences.These tests evaluated multiple aspects of randomness, including uniformity, independence and unpredictability.The findings showed that RNGs passed 97.34% of all Dieharder tests for 53-card games and 98.25% for 106-card games.P-value distributions were largely uniform in both cases, with only minimal clustering at the edges, which is consistent with theoretical expectations.'These results demonstrate a high level of statistical conformity and provide reassurance about the robustness of RNG implementations in digital card games,' said Dr Biswas. 'In games such as online rummy, the underlying randomness must be beyond reproach.'FIRST ACADEMIC VALIDATION OF REAL-WORLD RNG DATAThis is the first time in the skill-based Real Money Gaming and wider global gaming industry that an independent academic body has analysed actual gameplay RNG data.The IIT-BHU team conducted multiple Dieharder tests, such as the Birthday Spacing Test, Bitstream and Rank Tests, Parking Lot and Minimum Distance Tests, and DNA and OPSO/OQSO Tests.The results consistently confirmed no detectable bias or predictability in RNG outputs.REGULATORY AND INDUSTRY SIGNIFICANCEThe report highlights the regulatory importance of these findings. RNGs in digital gaming are subject to audits under standards like NIST and the British Remote Technical Standards.The IIT-BHU study confirms that the tested systems meet these benchmarks.RummyCulture, which previously earned RNG certifications from iTech Labs (ISO 17025 certified), sees the study as a reaffirmation of its commitment to fair play.According to the platform, such independent validations help maintain ethical standards, boost player trust, and ensure sustainable growth for the online gaming industry.- Ends

IIT Delhi's new method to cut textile waste, recycle discarded denims to good quality garments
New Delhi: A team of researchers from IIT Delhi has developed a new method to recycle denim waste to knitted garments without compromising quality. The findings will also help reduce textile waste -- the discarded textiles and clothing after their use -- which end up in landfills. India accumulates around 3.9 million tonnes of domestic post-consumer textile waste annually, of which only 4 per cent is recycled. Those recycled lose fibre strength and face variability in colour and quality. However, with the novel method, the IIT researchers found that up to 50 per cent of recycled yarns can be used in knitted clothing without deteriorating the feel of the product. 'To reduce the roughness of recycled yarns, a softening treatment was applied to the fabric, which ensured that the tactile feel of the final product is the same as that of virgin products, said Prof Abhijit Majumdar, Dept. of Textiles and Fibre Engineering, IIT Delhi. 'We have demonstrated our work with denim waste, and it can be extended with any other textile waste,' he added. In the study, detailed in the Journal of Cleaner Production, the team recycled waste denim into yarns, ensuring minimum damage to the fibre properties by optimising the process conditions. Recycled yarns were then blended into knitted fabric using the seamless whole garment technology. Knitted garments were produced, varying the recycled yarn content from 25 per cent to 75 per cent. Another key aspect of this research was to quantify the environmental benefits through life cycle assessment (LCA) in the Indian context. Analysis by the IIT Delhi team showed that around 30-40 per cent of environmental impacts can be mitigated in terms of greenhouse gas emission, acid rain, and fossil fuel depletion, whereas for ozone layer depletion, it is around 60 per cent. As the use of recycled fibres could reduce the use of virgin cotton, the pesticides, fertilisers and water used for cultivation can also be saved. Among the processes involved, the cotton cultivation stage itself contributes 24 per cent to global warming, making the virgin yarns less environment-friendly. 'The research team is now exploring the possibility of recycling textile waste materials multiple times,' added Prof B.S. Butola, Dept. of Textile and Fibre Engineering, IIT Delhi.

Video: IIT Hyderabad tests AI-based software to operate driverless buses within its campus
The Indian Institute of Technology (IIT) Hyderabad's Technology Innovation Hub on Autonomous Navigation (TiHAN) has created artificial intelligence-based software to operate driverless buses within its campus. The system is being used to transport students and faculty members between various locations inside the institute. According to TiHAN officials, the autonomous vehicle currently operates only within campus limits and not on public roads. Since its deployment, the bus has transported more than 10,000 passengers. Around 90 per cent of users have provided positive feedback, the team said. The technology relies on an array of sensors and can be adapted to different types of vehicles, ranging from electric to internal combustion engine models. The service has drawn interest from other educational institutions and the Telangana state government, which are exploring potential applications. Developers noted that the technology may be suitable for deployment at airports, large educational campuses, or industrial sites, where traffic conditions are relatively predictable. In an effort to adapt the system for Indian road conditions, TiHAN has undertaken extensive data collection. This includes trials with a specially equipped sport utility vehicle (SUV) travelling from Hyderabad to Jammu. The project, called 'Safari', covered approximately 4,000 kilometres in one direction, with the return trip bringing the total to about 8,000 kilometres. During the journey, the team passed through nearly 35 cities, gathering information on different road types, traffic patterns, and environmental conditions. The collected data is being used to train and fine-tune the autonomous navigation algorithms, with the aim of improving performance in diverse weather and traffic situations. TiHAN engineers stated that the system has been tested successfully in controlled environments, but further evaluation in uncontrolled, real-world conditions is necessary before any broader commercial roll-out can be considered. Officials involved in the project also highlighted the potential safety benefits of autonomous technology, particularly in reducing road accidents and fatalities. However, they emphasised that rigorous trials and regulatory approvals will be required before the technology can be introduced for general use beyond controlled premises.

IIT-I's AI system to forecast air quality in Indian cities
Indore: The Indian Institute of Technology (IIT) Indore has developed AeroVision , a weather forecast system designed to predict air quality for the next six days in Indian cities and towns. By analysing 12 years of hourly air quality data alongside weather and atmospheric information, the system forecasts levels of six key pollutants-PM2.5, PM10, CO, SO₂, NO₂, and O₃-with accuracy consistently above 95%. Developed by Prof. Manish Kumar Goyal and his research team, including Kuldeep Singh Rautela from the Department of Civil Engineering, AeroVision utilises advanced artificial intelligence technologies such as Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM), and Gated Recurrent Units (GRU). The system also collects weather data including temperature, rainfall, wind speed, air pressure, and humidity, as well as atmospheric conditions like the vertical dispersion of pollution and hours of sunshine. Professor Suhas Joshi, director of IIT Indore said, "AeroVision is a step towards empowering citizens with the ability to foresee and mitigate the health impacts of air pollution. By providing reliable, location-specific forecasts, it aligns with our vision of using science and technology for societal well-being and sustainable living." The data is gathered hourly from a 25-kilometre grid across various regions. Professor Goyal added, "This system converts complex pollution data into a simple, colour-coded Air Quality Index (AQI) following Indian standards, along with health warnings and activity recommendations. It enables individuals, communities, and policymakers to plan outdoor activities, take preventive health measures, and respond to pollution events in advance." The AQI operates similarly to a traffic light system: Green (0-50) indicates good air quality, Yellow (51-100) is moderate but requires caution for sensitive individuals, Orange (101-200) is unhealthy for sensitive groups, Red (201-300) is unhealthy for everyone, and Purple (301+) is very unhealthy, advising avoidance of outdoor activities.
