The rebirth of an old system that is illuminating remote villages in India: the hydraulic wheel

by

While the big cities They have opted for self -consumption through solar panels and even wind turbinesmany remote areas of the world still fight to have a renewable system. However, in Kashmir, they have found a cheap, effective and inspired solution in the past: the hydraulic wheel. An old advance. Surely the name of the hydraulic wheel will not come a direct image to the head, but if I describe a inn away from an village in the central European area, which had a large wheel shape that spinned with the water can be more enlightening. The fact is that they were important during the industrial revolution To perform mechanical tasks such as milling or hammering. However, its use began to decrease with the expansion of burning fossil fuels and the development of electricity. However, like fashions, everything comes back, and more if the original idea was good. So with the rise of renewable energies, hydraulic wheels have resurfaced as a viable option to produce electricity in a clean and continuous way in remote and impoverished areas. A new clean source. Initial investments in renewables usually have a high cost that not everyone can afford. But what if they turn to an old energy system? That is what a group of researchers from the Technical University of Munich thought that They have managed to install A hydraulic wheel in a town of Kashmir, India. The wheel in question measures about two meters and lets the stream water pass to produce electricity. In this way, it provides an uninterrupted energy source to the community, so it does not need centralized power, which was previously a problem with frequent cuts. In addition, the hydraulic wheel is accompanied by the use of other renewable energy systems, including the Decentralized microredwhich allows the inhabitants of the people to enjoy energy independence and resilience before a possible blackout. Self -sufficient One of the highlights of the hydraulic wheel is its high efficiency, reaching the 85% energy conversion. As for the assembly cost of this system, it is relatively low, around $ 1,000, so it makes them accessible to different impoverished rural communities. In addition, the design is available on the Internet for free. Only in rural areas. Hydraulic wheels are designed for rural and remote areas, specifically in communities that need a continuous and reliable energy source. This type of system offers a simple and economical way to generate electricity without depending on fossil fuels or intermittent energy sources. In addition, its environmental impact is minimal, since they do not emit carbon and, According to studiesdamage to aquatic life is reduced. While this type of technology has limitations and is not suitable for all contexts, its potential to improve the energy self -sufficiency of small communities could make a considerable difference. More for the world. The benefits of this technology are not limited to Kashmir. A similar system has been implemented in Nepal and a prototype has been developed in Tegernsee, Germany. In addition, in Northern Ireland, a hydraulic wheel has been restored with an old mill in Fermanagh County, which now supplies electricity to a restaurant.

An AI system will process a data flood

by

Madrid and other parts of Spain are being filled with cameras with artificial intelligence (AI). The City Council of the aforementioned city has been expanding its ambitious video surveillance system, focusing on points of great influx of public roads. But the expansion of these technologies does not stop there. In parallel, Renfe is developing an intelligent security system, where algorithms play a key role. Cameras in more than 400 vicinity stations. The rail transport company The installation has ended of an intelligent video surveillance system in 415 seasons of vicinity throughout Spain. The same has several pieces, among which IP cameras, CCTV recorders, video analytics servers and, as we said, algorithms of AI that give life to what they have called “spaces of high predictive security.” How does the new Renfe smart video surveillance system work? Traditional video surveillance systems depend on human supervision: it is the operators who must identify situations that require intervention. However, technology is reliefing this load when analyzing images in real time and sending automatic alerts to security centers when necessary. In the case of Renfe, the cameras are connected to the analytical servers of each station, in charge of detecting maximum afor and agglomerations. In addition, they allow identifying those who try to sneak into the accesses, falls in platforms or roads, fires and acts vandalism such as graffiti or damage to the furniture. The alerts arrive directly to the 24 -hour Safety Center of Renfe, promising to speed up the response to incidents. The rail operator recognizes that her security system had been obsolete. Although it had thousands of cameras spread over hundreds of stations, they lacked the technology necessary to integrate into the new monitoring system. To solve this limitation, the RS3 project (Renfe Smart Security Station) was launched, whose first phase has just concluded and whose second phase will begin in March. A millionaire investment. The project has a budget of more than 32 million euros and aims to modernize 597 stations distributed among the 12 Cercanías and Rodalies nuclei. The first phase, already completed, has been an investment of 25.8 million euros, while the second, which will cover the renewal of the systems in 182 additional stations, will have a budget of 6.5 million euros. Financing comes from the NextGeration funds of the European Union. What about the data collected? Every time there is talk of data collection, the doubt about the impact on user privacy arises. This makes sense if we take into account that European legislation is very strict in this regard. Renfe’s new video analytics system manages a large amount of data, but the company says it has taken measures to comply with the existing regulations. The system collects video images anonymously. Does not capture or record audio. Nor is biometric data. Processing is performed automatically with AI. The data collected are eliminated after “milliseconds.” In the case of the standard video surveillance system, the images are preserved last a maximum period of one month. The company’s privacy policy for your video analytics system states that users can exercise their rights, including the right to oblivion, opposition, suppression or limitation of data processing, sending an email to rights.viajeros@renfe.es. In addition, it offers A detailed map with the stations that already have the new security system.

“Eye of God” is your autonomous driving system and will be free in all your cars

by

Do we want our cars to drive alone? It is one of the great questions about which the automotive market seems to turn. Companies, of course, seem to be clear about the answer: yes. Beyond the obligations of the European Union in security matters (which already forces to ride assistants such as emergency braking or lane change alert), it is clear that efforts for Offer highly assisted systems in driving They are there. The manufacturers have been highlighting the functions for an automated vehicle parking for some time. From Online parking lotsuntil they square the car in a minimum space Based on burning wheelthrough vehicles that Remember the path they have circulated and thus save really narrow spaces or cars that They function like a robb In a parking lot. But it is Tesla and especially Chinese manufacturers who seem to be more interested in demonstrating to what extent they have the best semi -automatic driving systems. They believe there is a huge business to explode and Byd has just knew an important blow to Tesla. Autonomous driving as a differential value From Tesla they have tired of selling us autonomous driving as the great business of the future for the company. His Tesla Cybercabthe attempt to put a completely autonomous robotaxi on the street that lacks flyers and pedals, is the most obvious attempt. But this is just the tip of the iceberg. The company has been selling its semi -automated driving functions for years with promiseseven that now they see very complicated to fulfill and that They will cost Tesla a good money. Elon Musk has made his Autopilot and the Full self driving Be a sufficient value to opt for Tesla rather than for the competition. In the United States, promoting the system is key because they aspire to make vehicles themselves in automatic mode (under supervision) help them improve the system they are developing for their robotaxis. They believe that they can get a huge database to which Cruise or Waymo never arrived. But where there really is a really bloody battle in economic terms it is in China. In fact, Musk himself has made all possible efforts For Tesla to be allowed to map the streets to develop their autonomous driving systems. They are aware that in a market where the price is being differential and Chinese brands continue to tighten stronglya good performance of these systems is differential to sell as a key incentive before a future purchase. Obviously, they are not the only ones who believe it. During the presentation of Xiaomi Su7the Chinese company focused an important part of its efforts on demonstrating the autonomous capabilities of its car. Not only taught how the car reads the environment, they came to demonstrate how the vehicle It worked with absolute autonomy within a public parking lotI found a space where to park and maneuver between different obstacles. That same demonstration of strength (or higher) is what has made byd with the presentation of its “Eye of God”. The most surprising thing has not been that they sell the automated driving functions of their cars, they have also made an important announcement: incorporate it for free to all their vehicles. A missile in Tesla’s flotation line that sought to make these systems a business added to its vehicles, A way to profitable with permanent subscriptions or purchases at high prices these services. Until now, Byd only had this service in its middle and high -end vehicles but The company has announced which will be available for free in all its electric cars, from the economic Byd Seagullone of the electric models best selling in the country. During the announcement, Wang Chuanfu, founder of Byd, mentioned That automated driving functions have become basic safety equipment, at the seat belt or airbag level. The Chinese company also confirmed that it was integrating models of Deepseek in its functions controlled by artificial intelligence to improve the autonomous capacity of vehicles. The announcement is A bomb within the Chinese market. The local market is leaving aside the classic characteristics that have attracted cars to focus on advanced functions such as deeper infotainment systems or autonomous driving. Xpeng either Child They have tried to position their products as advanced vehicles in this regard without achieving profitability. Xiaomi, as we said, He showed these functions in the presentation of its first electric car. Incorporating these services in an electric car that, at direct change, is sold for less than 10,000 euros in China is a declaration of intentions and can be an important impulse to sales, something that the Chinese state seeks that has continued to expand the aid to the purchase of these cars with the aim of keeping alive an industry that is manufacturing much more of the vehicles you can buy while trying to continue promoting the consumption of citizens Faced with the slowdown in growth.

This is how this silent (and advanced) system called XProtect works

by

Malware is not an exclusive threat to PCs. Macs can also become infected. For this reason, there are different third-party security solutions, such as Bitdefender, Intego, Malwarebytes or Avast, among others. What not many people know is that Apple computers have, for more than a decade, had a integrated antivirus called XProtect. XProtect It has been running silently in the background since it landed on Mac OS Unlike Windows Defender, there are no icons in the menu bar, nor do we have an application to manually perform system scans. How does XProtect work on macOS? The Apple ecosystem has a variety of protection measures, and XProtect is one of them. If we focus on macOS, the Mac operating system, Apple tries to avoid the malware from the App Store. The company reviews the applications so that no malicious software lives in its store, but let’s be honest, we don’t always use the App Store. Computers have always given us the freedom to install any compatible external software. To address the issue of external threats, Apple has a certification mechanism, where developers who do not use the App Store to distribute their applications can obtain a trusted certificate for macOS. Apple does not take this task lightly. Scans the applications and grants the certificate only when it cannot find known malware. Once this instance is passed, developers receive a certificate that they can attach to their application so that the target system can verify it, even when it does not have an Internet connection. At this point we find another of the protection measures. This is Gatekeeper, which looks for that certificate in the application that the user is trying to open or install. If the program does not have the corresponding certificate, the system warns users that they are trying to use software that cannot be verified. Since not all developers go through the certification processwe can ignore that message to use the application in question. Sometimes we will have to allow the installation of applications from the App Store and well-known developers from System settings > Privacy and security > Security > Allow applications from… XProtect is responsible for preventing the execution of malicious software. If for any reason the protection measures mentioned above have been violated, XProtect is responsible for preventing the execution of malicious software for the first time or detecting malware that has been executed on the computer. This integrated antivirus uses YARA signatures that are automatically updated periodically. XProtect comes into action at three key moments: when opening an application for the first time, when modifying an application in the file system, and when updating security signatures. If you detect known malware, blocks it immediatelynotifies the user and offers the option to send the software in question to the recycle bin. XProtect’s scope does not end there. Apple has improved the system to address problems that certain infections can cause. Once malicious software is removed, the built-in antivirus continues to scan for threats using a behavioral analysis engine. Of course, it does not have the ability to restart the computer. How do you update macOS built-in antivirus? XProtect updates automatically. However, you can buy if the system is installing the updates automatically. To do this, click the apple icon in the toolbar and then go to System settings > Software Update. Then tap the information icon under Security Answers. In the Automatic Updates category make sure the Install security responses and system files switch is turned on. So am I completely sure now? Although macOS has a solid security system, it is important to clarify that no system is 100% secure. In the world of cybersecurity it is often said that what is sought is to increase the level of difficulty for cybercriminals. And we achieve this in many ways. Integrated system tools are only part of this. The security features of the applications themselves, our security practices and, if necessary, third-party security tools also come into play. The level of difficulty varies according to the needs of each user. For example, for a long time iPhones and Macs can activate Isolation Mode. This is an extreme solution, but it is a good example of what it means to put higher barriers. This mode limits the functionality of applications, web pages, and certain system features. As a result, we obtain a more protected system, but much less useful than in its standard configuration.
