NASA approves University of Evora's project to map forest fuels via satellite

The North American Space Agency (NASA) recently approved the project “Evaluating the Usefulness of ICESat-2 Data for Wildlife Fuel Mapping»Led by Sergio Godinho, Researcher at the Remote Sensing Laboratory (EarsLab) at the Institute of Earth Sciences (ICT) at the University of Évora (UÉ), who intends to use remote sensing to develop innovative methods for mapping forest fuels and provide the necessary mapping to support planning and management of activities for prevention and suppression of forest fires.

The goal of the developed project is to test and combine a set of methodologies that allow converting the laser signal emitted and recorded by the ICESat-2 satellite into quantitative information, obtaining accurate data on the structure and quantity of vegetation on the Earth’s surface. as part of the ICESat -2 NASA Application User Program.

This satellite by NASA, launched in 2018, possesses the latest technologies to create a three-dimensional global portrait of our planet… Orbiting almost 500 km, ICESat-2 allows Extremely accurate mapping of our planet and terrain, which allows scientists to track changes in the terrain, including melting glaciers, sea level rise or changes in vegetation, based on the data obtained.

It is in this latter area that a project led by Sergio Godinho, recently approved by NASA, is included. O sensorAdvanced Topographic Laser Altimeter System (ATLAS), ICESat-2 satellite, sends laser pulses to the surface of the Earth and collects photons through a telescope, which are reflected back into space.… By registering the travel time of photons between the Earth’s surface and the telescope, ATLAS converts this time into distance traveled using a constant speed of light. Knowing the exact position of ICESat-2, using the high-precision GPS built into the system, the distance traveled by the photons is converted into height, that is, for each registered photon, it will be associated with its coordinate and height.

Based on this information Researchers will be able to reconstruct the vertical profile of vegetation, which will generate a set of variables such as crown height or crown base height, among others, and then estimate the amount of milled biomass listed above.

The project coordinator at UÉ underlines the importance of this project, which will allow, over the next 3 years:collaboration with some of the world’s best researchers and scientists in the field of LiDAR technology*from space, but it will also be a way to project the name of UÉ, making it appear as a specialized investigation of forest fires, a pressing problem of modern society.“.

About ICESat-2

The ICESat-2 Application User Program is designed to assess how ICESat-2 spaceflight can directly benefit society in various areas (forests, agriculture, biodiversity, atmosphere, etc.). For this purpose, NASA selected a number of research projects aimed at testing, calibrating and validating ICESat-2 data for various scientific applications, with a project presented by an ICT researcher being one of the award-winning projects.

Learn about the extended RAM feature coming to mobile phones and tablets |  Cell

Virtual RAM, also known as RAM Plus – is a memory expansion feature that is increasingly used in cell phones from major manufacturers. brands like Samsung e xiaomi to make the feature available on some smartphones, such as Galaxy devices in the case of the South Korean one, and some models of the POCO, Redmi and Mi series, on the Chinese side. The function uses the free part of the cell’s memory to expand the RAM and thus improve the performance of the device. OUR Apple also recently announced such a feature for ipad.

The iPhone manufacturer revealed the functionality during the presentation of new items iPadOS 16 at the beginning of June. The operating system update will bring for those devices that are equipped with M1 or M2 processors, the replacement of virtual memory. According to Apple, the update will use ipad offer up to 16GB of storage to help run the heaviest apps like phones do android.

How virtual memory works

Virtual RAM is not native to devices and became available after a software update. That is, everything will depend on how up-to-date the user’s operating system is, and even so, this is a feature that is far from being released to everyone. The available size depends on the smartphone. when Samsungfor example, Galaxy A52S can be used additionally up to 4 GB, but Galaxy A53 you can use up to 8GB more via RAM Plus.

when Applewhich provides additional memory for iPad models only ipad 11″ Pro (3rd generation), ipad 12.9″ Pro (5th gen) and ipad Air 5th generation, equipped with the giant’s own processors, will be able to use this feature. OUR xiaomi more democratic, with more than 30 compatible devices, including Xiaomi Mi 11, Redmi Note 10 Pro 5G, Poco F3 and others.

Benefits of using virtual RAM

Among the benefits of enabling virtual RAM is the ability to run multiple applications at the same time without crashing, as the system allocates storage according to the needs of the device – but, of course, within the limit set by the manufacturer. Heavier applications that require more from smartphones can be downloaded and used without delay.

Disadvantages of using virtual RAM

Despite the performance benefits, there are some limitations that the user must be aware of before enabling a significant amount of virtual RAM. First, even with the addition of RAM, the performance is not the same as the physical version. It is also not possible to disable this feature on devices that support this feature.

That is, if your phone has 128 GB of internal storage, at least 2 GB will be dedicated to the device’s virtual RAM, which will reduce the space to 126 GB. Also, using this feature to use a heavier application may result in performance degradation of other applications running in the background.

It is important to note that in order to use this function, the mobile phone must have free internal memory, that is, it cannot be occupied by files of any nature or systems. Otherwise, the function cannot be activated. on the site Samsung, the manufacturer itself warns of the limitation “RAM Plus is a technology that uses part of the smartphone’s internal memory as RAM. You must have free space on the internal memory, ”is written in small print on the manufacturer’s website.

How to find out the amount of virtual memory on your mobile

for instruments xiaomi, the path is almost the same: Settings > Advanced settings > Memory expansion and enable the function. On devices from both manufacturers, you must restart the cell phone after activating or selecting the amount of virtual RAM to use. When iPadOSYes Appledespite what has been announced, this feature will only be available when the new operating system becomes available for new devices, which should happen in the second half of the year.

This app allows you to watch YouTube videos on your Apple Watch.



The Apple Watch certainly has a range of interesting features for users, but watching YouTube content is not one of them. Or at least it wasn’t, considering there’s now a new app available that lets you do just that.

The new Apple Watch app from WatchTube allows users to use their Apple smartwatch to watch YouTube content directly. The app works on all devices running watchOS 6 or higher and can be downloaded from the App Store.

For now, WatchTube allows users to search for videos, check the history, description, and even like videos. The content is played on the small screen of the device, and the interface is also adapted for this.

The developers say that in the future they hope to launch an audio mode that will allow content to be played in the background even when the watch screen is off.

An important feature will be that users will be able to generate QR codes from videos directly from the application to quickly share them with third parties or even continue watching on a smartphone.

This app is certainly not intended to replace using YouTube on your smartphone, but it can be a fun way to quickly browse some content or even continue playing a song without using your smartphone.
