What is decarbonization.

Decarbonization is a process of

reduction or elimination of carbon dioxide from energy resources.

Why do we need it.

For the climate to stabilize the world need total decarbonization. Currently, we are on the track of making the global average temperature rise for 2-celsius degrees and above. Considering the melting of the glaciers, the water level of the seas has risen 6 meters since the world was industrialized and the average temperature is 2-celsius degrees higher. If carbon emissions won’t be stopped, average warming will increase to 3-celsius degrees, which will result in flooding many cities, including Miami, Shanghai, Osaka, Rio De Janeiro (the equivalent of 275 million people losing their home).

Ways of decarbonization.

Companies are trying to decarbonize the economy, which results in changes in their business models and many new technologies emerging. Renewable sources of energy are prioritized over fossil fuels. New energy carriers have been created, energy efficiency has been improved, emissions are being reduced.

Companies are taking steps to decarbonize the economy, including increasing electrification, usage of renewable energy, or intensifying energy efficiency measures, which are still a big challenge for the coming years. However, most of the companies declare being fully carbon-neutral by 2050.

Sector overview.

Surface Technology in the chemical Industry | Aalberts ST

The chemical industry is built on hydrocarbons, however, decarbonizing it would have a profound effect on the world. New technologies make it possible to use CO2 as a feedstock for chemicals and plastics. Moreover, Waste-to-hydrogen plants are being built.

The oil and gas market is currently in crisis, considering low demand caused by the global pandemic and excess supply from the recent oil price war. Decarbonizing may be prioritized by some companies in the short term, though difficult market conditions may encourage companies to experiment with it more and create new business models.

The power, utilities and renewables sector is moving the fastest towards decarbonization as it is a key attribute of customer engagement. They are largely working to expand their renewable energy portfolios. They increase the efficiency of their thermal power plants and improve energy efficiency in buildings.

The mining and metals sector relies mainly upon electrification and renewables. Most of the companies design their decarbonization strategies based on proven solutions and applying them globally to their facilities.

Telehealth

Reading Time: 2 minutes

Medicine and healthcare has developed greatly in the recent times. It has become inseperable aspect of our lives. In current times it is so advanced that it prolongs lives on earth and enables reaching an average of 72 years of life expectancy. With technology advancement medicine is constantly perfected. Today healthcare can be provided remotly which was called telehealth service.

Using digital information and communication technology devices, we are able to supervise one’s state of health without having to meet in person. The main goals of telehealth are enabling access to healthcare to people in isolated communities, making service more dynamic and time saving, improve coordination between patient and specialists. Many clinics provide service of telecare by managing a patient portal. Thanks to it, you can communicate easily with your doctor or nurse. You can also schedule appointments, show your previous visits results, or even request prescription refills.

Virtual appointments are one of the reasons telehealth exists. It allows a person to attend an appointment with doctor through videoconference. Thanks to that, people may recieve care when regular appointment isn’t required or possible. For example treating a minor illness doesn’t require you to leave your aparment, merely describing your state through a device to a doctor. Moreover your doctor is able to conduct a consultation with a specialist instantly if needed. After loging in to a web-service, you are being asked a series of questions based on which a nurse determines what kind of care should you recieve and if it can be managed virtually or if your state should be furtherly inspected. Despite the fact that the service is convinient it has some disadvantages including not being able of being treated by your doctor, lack of in-person evaluation or the computer driven decision making model may not preprocess correctly your medical history in case it is complex.

In the times of global pandemic telehealth service takes an important part in healthcare. As previously it served only as a way of convenience for patients, now it is crucial and is developed dynamicly. Thanks to remote diagnosis, patients do not risk being infected with SARS-CoV, as they do not leave their house or make any direct contact.

In my opinion telehealth service is not developed enough to replace a regular appointment. However in times of COVID-19, when aspect of remoteness is heavily prioritized in many services, it may come to that telehealth will be sufficient way of healthcare.

Image creator program GauGAN

Reading Time: 3 minutesWHAT IT IS
Created by NVIDIA Research GauGAN project is a program which allows you to turn simple paintings into photorealistic pictures using AI technology.

HOW IT WORKS
GauGAN gives you blank space to draw on, where each brush type is labeled with different type of environment like sand, grass, sky, ocean. Option of changing daytime is also available. Then AI converts the sketch filling into desired elements basing on online pictures database. Using GANs technology program creates credible outcome. In the process two neural networks are used where one is called generator and the latter one discriminator. Generator creates image that later is corrected by discriminator in terms of authenticity.

GANs SYSTEM
Gaugan is using GANs (Generative Adversarial Networks). These are neural networks that cooperate in the process of deep learning, by competing with eachother. E.g one is creating a fake cat picture, while the other one determines whether it is real or fake. This eliminates the need for human to correct the AI and automatizes the process. This way human effort in advancing neural networks is minimized.

USE IN WORLD
In the future the application can help proffesions which require creating world representations like architects, urban planners or game developers. It would allow them to preview the outcome of their work with minimal effort and prevent from committing to bad ideas.

INSIGHTS
Current state of the project may be impressive but its very restrictive. The fact that you are allowed to use only certain labels which resemble specific parts of environment is disappointing and prevents from exploiting maximum potential of creativity. The most obvious way of solving that problem would be adding more labels but connecting elements from various types of environments could corrupt the final landscape. E.g covering a desert with a snow or placing a star on the dirt background would distort the picture, because AI would have no data to refer to. Project’s advancement is dependent purely on describing parts of the world with new algorithms and putting them to the GANs test.

 

EXAMPLES – Here are some masterpieces I’ve created.

REALISTIC EXAMPLE – easy to make, low chance of corruption

CORRUPTED EXAMPLE – elements added to habitat in which they not occure will distort the picture. Here is a house in the middle of the ocean with a bridge connected to a pile of mud above.
