Optimal Characteristics of Inspection Vehicle for Drive-by Bridge Inspection
Hurtado, A. Calderon, Atroshchenko, E., Chang, K. C., Kim, C. W., Alamdari, M. Makki
Drive-by inspection for bridge health monitoring has gained increasing attention over the past decade. This method involves analysing the coupled vehicle-bridge response, recorded by an instrumented inspection vehicle, to assess structural integrity and detect damage. However, the vehicles mechanical and dynamic properties significantly influence detection performance, limiting the effectiveness of the approach. This study presents a framework for optimising the inspection vehicle to enhance damage sensitivity. An unsupervised deep learning methodbased on adversarial autoencoders (AAE)is used to reconstruct the frequency-domain representation of acceleration responses. The mass and stiffness of the tyre suspension system of a two-axle vehicle are optimised by minimising the Wasserstein distance between damage index distributions for healthy and damaged bridge states. A Kriging meta-model is employed to approximate this objective function efficiently and identify optimal vehicle configurations in both dimensional and non-dimensional parameter spaces. Results show that vehicles with frequency ratios between 0.3 and 0.7 relative to the bridges' first natural frequency are most effective, while those near resonance perform poorly. Lighter vehicles require lower natural frequencies for optimal detection. This is the first study to rigorously optimise the sensing platform for drive-by sensing and to propose a purpose-built inspection vehicle.
Privacy in the Age of AI: A Taxonomy of Data Risks
Billiris, Grace, Gill, Asif, Bandara, Madhushi
Artificial Intelligence (AI) systems introduce unprecedented privacy challenges as they process increasingly sensitive data. Traditional privacy frameworks prove inadequate for AI technologies due to unique characteristics such as autonomous learning and black-box decision-making. This paper presents a taxonomy classifying AI privacy risks, synthesised from 45 studies identified through systematic review. We identify 19 key risks grouped under four categories: Dataset-Level, Model-Level, Infrastructure-Level, and Insider Threat Risks. Findings reveal a balanced distribution across these dimensions, with human error (9.45%) emerging as the most significant factor. This taxonomy challenges conventional security approaches that typically prioritise technical controls over human factors, highlighting gaps in holistic understanding. By bridging technical and behavioural dimensions of AI privacy, this paper contributes to advancing trustworthy AI development and provides a foundation for future research.
How China is challenging Nvidia's AI chip dominance
How China is challenging Nvidia's AI chip dominance The US has dominated the global technology market for decades. But China wants to change that. The world's second largest economy is pouring huge amounts of money into artificial intelligence (AI) and robotics. Crucially, Beijing is also investing heavily to produce the high-end chips that power these cutting-edge technologies. Last month, Jensen Huang - the boss of the global AI chip industry leader, Nvidia - warned that China was just nanoseconds behind the US in chip development.
Poland scrambles jets as Russia strikes western Ukraine
Russia pounded Ukraine with missile and drone attacks overnight on Saturday and into Sunday morning, focusing on the major western city of Lviv. Ukraine's neighbour Poland scrambled fighter jets in order to ensure the safety of Polish airspace, the Polish military confirmed. Allied Nato aircraft were also deployed. Lviv's regional head Maksym Kozytskyi said two people were killed in strikes in the region, and two more injured. Elsewhere, Russia again targeted Ukraine's power plants - and one was struck in an overnight attack on Zaporizhzhia, where the mayor said one person died and more than 73,000 people were without electricity.
At least 30 injured in Russian strike on railway station, Zelensky says
At least 30 people have been injured following a Russian drone strike on a railway station in north-east Ukraine, Ukrainian President Volodymy Zelensky has said. In a post on X, he said that preliminary reports indicated train staff and passengers were at the site of the strike in the city of Shostka, in the Sumy region. Emergency services are on the scene and have begun helping people, he said, adding that information regarding the injured was still being established. He also posted a video showing a damaged train carriage on fire. The Russians could not have been unaware that they were targeting civilians.
OpenAI launch of video app Sora plagued by violent and racist images: 'The guardrails are not real'
'In a video documented by 404 Media, SpongeBob was dressed like Adolf Hitler.' 'In a video documented by 404 Media, SpongeBob was dressed like Adolf Hitler.' OpenAI launch of video app Sora plagued by violent and racist images: 'The guardrails are not real' OpenAI launched the latest iteration of its artificial intelligence-powered video generator on Tuesday, adding a social feed that allows people to share their realistic videos. OpenAI's own terms of service for Sora as well as ChatGPT's image or text generation prohibit content that "promotes violence" or, more broadly, "causes harm". In prompts and clips reviewed by the Guardian, Sora generated several videos of bomb and mass-shooting scares, with panicked people screaming and running across college campuses and in crowded places like New York's Grand Central Station. Other prompts created scenes from war zones in Gaza and Myanmar, where children fabricated by AI spoke about their homes being burned. One video with the prompt "Ethiopia footage civil war news style" had a reporter in a bulletproof vest speaking into a microphone saying the government and rebel forces were exchanging fire in residential neighborhoods.

'Delivery robots will happen': Skype co-founder on his fast-growing venture Starship
'Delivery robots will happen': Skype co-founder on his fast-growing venture Starship C ity dwellers around the world have long been used to rapid delivery of takeaway food and, increasingly, groceries. But what they are not entirely used to - yet - is the sight of a robot pulling up to their front door. The co-founder of Skype, Ahti Heinla, believes his new venture is about to change that. Heinla is the chief executive of Starship Technologies, a startup that, he claimed, is able to operate deliveries run by trundling robots at a small profit - and cheaper than a human delivery driver, even in small towns and villages where delivery has not previously been viable. "We've solved everything that there is to solve," Heinla said over lunch at a London hotel.
