A modified model designed to simulate nuclear fission sheds light on how rumors start, spread, and end. It has never been easier to spread false or misleading information online. The anonymous, impersonal nature of the internet, combined with advanced tools like artificial intelligence, makes it trivial for bad actors to manipulate the truth and challenging for everyone else to separate reality from fiction. In this modern climate of disinformation, understanding how falsehoods and rumors spread is crucial for combating them….
More than just loud bass! Loud or unpleasant driving noises can impair the enjoyment of music in the car. Some sound systems therefore dynamically adjust the volume and bass. However, individual sound preferences are not taken into account. A study from Fraunhofer IDMT in Oldenburg has now investigated the influence of background noise on the personal sound experience while driving – and shows how an adjustment of individual sound preferences once could improve the sound in the vehicle (and beyond)….
Researchers from Stanford and the American University of Beirut have developed a lightweight, portable antenna that can communicate with satellites and devices on the ground, making it easier to coordinate rescue and relief efforts in disaster-prone areas. When an earthquake, flood, or other disaster strikes a region, existing communication infrastructure such as cell phone and radio towers are often damaged or destroyed. Restoring emergency communications as quickly as possible is vital for coordinating rescue and relief efforts. Researchers at Stanford…
The system could be used for battery-free underwater communication across kilometer-scale distances, to aid monitoring of climate and coastal change. MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique, which the researchers began developing several years ago, uses about one-millionth the power that existing underwater communication methods use. By expanding their battery-free system’s communication range, the researchers have made the technology more feasible for applications such as…
European team use proprietary ‘SeaFi’ technology to send furthest wireless broadband transmission from ship-to-shore ever achieved without satellite. A team of scientists working off the west coast of Ireland have set a new world record for the furthest broadband transmission from a ship at sea back to land without satellite or cellular connection. The new record is 36.83km (19.9 nautical miles) set on Saturday, 26 May 2023, off the coast of the Aran Islands. The team based at Aran Island Research Station…
A method for personalized sound experience… Developing an audio device that offers optimum sound experience to all people is not easy. The great challenge is that each person has their own listening preferences. For this reason, the Oldenburg Branch for Hearing, Speech and Audio Technology HSA of the Fraunhofer Institute for Digital Media Technology IDMT has developed adaptive algorithms as well as intuitive methods for adjusting personal sound. Together with a customer, this technology has now been successfully integrated in…
… makes wireless communications more powerful. Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of information, thus producing unique advantages of metasurface-based wireless communications. In recent years, the proposal and development of time-domain coding metasurface (TDCM) and space-time-coding metasurface (STCM) have further enriched the electromagnetic modulation and digital process schemes and application scopes. However, most of metasurface-based wireless communication systems…
Automatic voice monitoring for the ship’s bridge. Many accidents at sea are due to errors in communication between seafarers. An automatic voice monitoring system for the ship’s bridge will ensure greater safety. With the speech recognition system and support from Fraunhofer IDMT in Oldenburg, Germany, ELNAV, a start-up company based in Split, Croatia, is developing what it calls a “Helm Order Monitor”. November 23, 2022. Communication in the maritime environment is important for safety but does not always run smoothly….
With the ART 4 … project, the artist, Bruno Wilbert, would like to increase general interest in the climate, environmental and nature conservation issues that are important to all of us, promote projects in these areas and thank people who have already shown exemplary commitment. During his extensive internet research on the topics of climate, environmental and nature conservation, he was not only impressed by the numerous fantastic projects in these areas, but also again and again by the enormous…
The Gutenberg Gait Database: Publicly accessible database provides a reference set of data to be used for the diagnosis and treatment of gait disorders / Further expansion of the database is planned. Gait disorders manifest themselves in various ways: One walks with small tripping steps, another drags a leg while walking. In one case, a foot does not roll over the sole of the foot, and in another, a foot is not lifted sufficiently but is rather dragged across the…
As digitization continues, connected devices are making their way into more and more areas of everyday life. However, these are often vulnerable to cyberattacks; in the past, many end consumers, such as users of online services, were affected in addition to industry and businesses. A German consortium of industry, university and research institutes aims to make these systems more secure thanks to light-based data transmission and computation. Over the next three years, the “Silhouette” project will develop universally applicable solutions….
Researchers at the Fraunhofer-Gesellschaft have developed an AI-driven technology that allows the perimeter advertisements shown during live broadcasts of soccer games or other events to be changed without viewers noticing. This means every TV station can show its own content on the boards. The Swiss company ViboTec AG is bringing this technology to the market. For sports fans who regularly tune in to track and field sports, soccer, or other events on their TVs, the long advertising boards on the…
Intelligibility Meter enables objective measurement and display of speech intelligibility in media productions. Scientists at Fraunhofer IDMT in Oldenburg are developing solutions to improve the intelligibility of speech in media. Algorithms for automatic measurement, evaluation and presentation of speech intelligibility facilitate the work of sound engineers in film, game and audio productions. With the implementation of intelligibility technology in Steinberg’s current production solution Nuendo, a traffic light now indicates how well the spoken words will be objectively received by listeners….
An exabyte is a multiple of a byte; specifically, it equates to 1,0006 bytes. Looking ahead to 2022, experts predict that the monthly data traffic passing…
Staff at telephone workstations are permanently confronted in their everyday work with different acoustic effects. Incoming calls vary in sound quality and…
The facts and figures of the new ship are quite impressive. “Mein Schiff 1” has a maximum passenger capacity of nearly 3,000 and accommodates 12 restaurants…
