but the 9 year old ticket has opened it up to a more diverse crowd. this weekend can be seen as a test for the summer to come for many travelers. it's a welcome chance to explore new areas and get a change of scenery and all for 9 euros. well, that's all for now off next, this shift 11 in the digital age. thanks a lot for your time. stay with us as small. coming up every journey begins with the 1st step and every language with the 1st word, louis pinnacle. rico is in germany to learn german. why not learn with him? simple online, on your mobile and free to shop d w e learning course, nikos vague. german made easy about us issue when i arrived here, i slept with a sick of people in

a room and it was harsh. fair. i even got white, harris and lemming. the gym and language head. yeah, i love this kid to me and they don't listen to nikki to interact with you want to know their story, the migrants verified and reliable information for migrant. with imagine there was a butcher replica of orth and we could use it to test all important decisions and that possible consequences for humanity. actually, it already exists, but does it do the work or is it just fun and games? why we need data to twins? i'll a topic on shift today, ah, shoot in a digital twin is a vessel copy of a physical object and it's programmed to behave realistically. for example,

a cause performance could be tested on a virtual road without having to build the vehicle. first, virtual copies of factories could even be used to optimize work flows of the all planning and testing in the virtual world saves an enormous amount of money resources and time. digital twins are being used in the growing number of applications. they could even make nuclear power plants safer. a cyber attack on a nuclear power plant. a horse scenario, conflicts between russia and nato surrounding the war and ukraine have renewed fears of this threat. based on api i information news agencies have reported that russian hackers have been scanning power plants for weak spots for years. scientists at the idaho national laboratory are therefore testing the 1st ever digital twin of a mini reactor. it can spot irregularities in the reactor immediately.

the twins are living virtual model that mirrors a physical asset to predict an act on that asset autonomous digital training to be used to prevent a director accident because a digital twin would have insights and predictions into that accident and long before happens and be able to see the conditions in the rector environment that would be leading towards that type of situation. alert users take no physical actions to prevent that kind of accident to ensure the digital twin behaves just like a physical nuclear power plant. the operating data from especially design test reactor, we're fed into the model every detail, even the tiniest valve was copied apart from preventing cyber attacks. the digital

twin can also detect signs of where in the used to test upgrades before they're built into the physical plant. the digital twin exchanges data with its physical counterpart in real time and is trained to react to the demands of modern energy policy. by using artificial intelligence. production could be curved automatically once sufficient energy from renewable sources is available. the goal is to build a framework and a pattern that we can apply to look lots of different reactors and lots different energy system pipes across the space. and one of the ideas of that is that a nuclear reactors can be a key part of that integrated energy system, right? generating thermal and electrical power currently is fully automated. energy management only exists in the test lab in idaho. but in many other research areas in industries, digital twins are already indispensable. today. digital twins are far from being

a vision for the distant future. for some businesses, they are essential, like the company unlimited to morrow, it specializes in 3 d printed prosthesis prosthesis used to be extremely expensive, especially for children who need new ones as they grow. but now, they as a solution, check this out. together with his team engineer easton, le chappelle from colorado designs individual arm prostheses in order to keep this process as simple and affordable as possible. they use software that creates a digital twin for each customer's individual prosthesis. or model relies on sunday and 3 d scanners to our users, or a family member or friend with scan the residual them. we collect that 3 d data and geometry and, and start creating sockets. the socket is how the device attaches to the person as really emerging man, a machine. it's not only an attachment mechanism to

a human body, but as lined with muscle sensors. so a child out of the box after 10 or 15 minutes of training, they can actually start moving their hands over 50000000 people in the world today have had an amputation, but only about 5 percent of them have access to medical treatment. using digital twins can make production quicker and more affordable. aaron frankl from siemens who produces the technical equipment and programs needed for this, sees it as a great opportunity. digital twins are important in remarkable because they give designers and engineers and manufacturers superpowers. and, and these superpowers enable these, this community to, to be able to create a turn new ideas and new innovations and physical products faster than they can with conventional methods. thanks to the software. unlimited to morrow can now

bring together the construction simulation and production processes in a digital environment. this way, individual prostheses can be customized undelivered in no time. this amazing story would not have been possible without a digital twin. now, that's what i called progress. the fact that digital models basically have no limits in size also fascinates me with enough computing power. anything could theoretically be copied digitally, really anything, even our planet. busy earth now has a twin, a digital twin. it's currently being developed in u. s. tech company and video as virtual reality. omnivorous in video simulation platform is used to study galactic winds or predict how hurricanes develop the simulations. we're going to scale of 10 to 100 kilometers,

which does not cover the full spectrum of global environmental issues. more data is needed to make predictions on global climate. based on the ai supercomputer, cambridge to earth, to is the software behind earth digital twin blue. it might be the 1st to have sufficient computing power to simulate global weather and to accurately copy our earth to a meter lou, it makes predictions $4.00 to $5.00 orders of magnitude faster. what takes a classical numerical simulation a year. now takes minutes. oh, this new supercomputer is currently being fed data. soon the data streams will be connected nurse to could then make global weather predictions and help us

understand which developments lead to increasingly devastating storms and trouts. the question is it, will it help us understand if we do carbon emissions, how it's going to affect the climate? and absolutely, you'll be able to do those types of things. but you'll also be able to understand other scenarios if something's taking place in one part of the world. how will it affect something else in the other part of the world? things like that. there's so many things that are, that are happening across the globe that we just don't understand all at once. and having a digital twin will allow us to kind of look at it from a bigger picture and understand the ramifications of something that might happen in antarctica. to the rest of the planet and videos, idea is to force governments to change the climate policy by visualizing the consequences of not acting. now. it's a multi year, very heavy investment project, but what we will have at the end of that is a digital twin of the earth that allows us to understand climate change. we will be

able to understand how the climate can be affected by things, whether it's things that we're doing now or we can understand what happened in the past that affected it. you could project what it's going to be like in the future. you could understand how different things are going to affect it without having to do it in the physical world. if digital twins could help science convince even the most stub on climate change deny, that would be amazing. we need to finally act. one approach is ecological building . amsterdam in the netherlands, is home to one of the world's most modern and energy efficient office buildings at the edge. they used digital twins to, oh, in this building sensors records almost everything such as temperature, brightness, movement. this information is then analyzed to understand how spaces are really being used. this is supposed to minimize energy consumption, explain sondra gritty from real estate tech company edge to base and have a digital version of this building in the cloud. where we can basically read

everything which is going on in the building and we can also run simulations. we can understand what if the weather will be like this. what would be happening in that regards that the potential of this digital twin during the lifecycle is to optimize the energy use during operation. but ecological building also requires real estate companies to start thinking about what comes after the building. that edge, they save all information on the construction in a digital data bank. they're the digital twin which is related to the material use in the building we've, as he stored all that information. so that an owner, when selling the building to another owner, would have all this information so that if the building is dismantled at some point, we can easily find all the information of what could be reused. and where could it be result that material gets in your life wall and it all looks great too. bye. now the i didn't twins of cars, buildings, factories, nuclear power plants and entire planets. but there are also the little things alive

. thanks to sensors and computerized ventilation and irrigation systems. smart green houses create high deal growing conditions for plants. the soil, air and lighting can be identical everywhere around the world. new data is constantly being collected. only having this set of data doesn't mean anything. you have to transfer that data into information, actionable insights, but to really understand how a plan growth was all the physiology in it. and really try to mimic that and improve it. that's where artificial intelligence combined with knowledge that is already there, can really improve the products and a plan. and even better way to do that is with a plant digital twin. that way there's no need for actual food production or arable land. one of the superpowers that the digital twin provides, the engineering community, is to be able to look into the future. and we can now ask questions about this

physical object that is in physical yet to determine if it's going to meet the expectations that we have. and that's quite incredible. this knowledge could help 5 starvation in the world. and the examples we've just seen showed that digital twins are helpful in finding solutions to humanities, most pressing challenges. how does flying affect the climate? how can we protect nuclear power plants from cyber attacks? how can we produce more sustainably? digital twins are the perfect testing ground for all these questions. i'm really excited to see what new insights we will gain from our digital earth. how about you? which digital twin would you be interested in? let us know on youtube or on d. w dot com. good bye, and soon, ah, help

with into the conflict with sebastian. how worry go. russia spies about the progress of the war? the small volumes of investigative journalists was managed to pierce the veil of secrecy among them. i'm very proud gotta founder and they said they are going through our website. with tract rushes and tele do services. it's really difficult for psychological eval. i'm flick zill because on the bottom, but on dealing with a cell play mother is going to spend the rest of her life behind bars for murdering her 3 dot. call me back with him. psychosis is an awful illness to him. but there is

a nightmare. in 30 minutes on d, w, a live and on demand. hot gas in language courses with video and audio. any time, anywhere. the d w media center now into its 2nd month, the war in ukraine has failed to give russia the quick victory of warranty. and there are signs of growing discontent among the political and security elite back in moscow. a small band of investigative journalists is managed to pierce the veil of secrecy around those official among them. address hold data founder and editor of the tour of website which tracks russia's intelligence services. he's my guest this week from london. how worry.
