What does the “we don’t understand how artificial intelligence takes decisions” statement mean?
Specialized media sometimes publishes similar headlines to the title of the present article. For instance 1, 2, 3, 4, 5 or 6. They are all referred to deep learning, which is a part of artificial […]
Simulating particle physics in a quantum computer
Particle physics is an interesting and complicated field of study. Its theoretical framework, the Standard Model, was developed during the second half of the twentieth century and it opened he possibility to explaining the behavior of the basic blocks of […]
Negotiating Wi-Fi channels to improve bandwidth in surveillance networks
Security in residential and public areas is a matter of great importance for many people. This is why some Internet providers are offering surveillance systems as a value-added service. Such surveillance systems have recently shifted from CCTVs to IP-based cameras, […]
Semiconductor devices: Transistors (2) – Applications
Amplifying Voltage
If we place a large resistor in a circuit containing a transistor we can amplify the incoming voltage, since according to Ohm’s law voltage is equal to current times resistance. So a current crossing a small resistance corresponds […]
System of quadrotors for the transportation of deformable linear objects
Nowadays, the industry is centering their efforts on the development of single aerial robots carrying single objects, such as the widely-known drone of Amazon for delivering packages, which was followed by some national post-office services. However, other approaches go a […]
A working molecular electronic switch
A visionary perspective of molecular electronics is the use of single molecules as functional entities in electronic devices. In this context, some of the most important components are molecular switches, which are molecules that can be interconverted reversibly between at […]
Wearable biosensors, the next level in the information age
They say that Information is power. Probably because having the knowledge, when the data are correct, it is essential to anticipate the right move that will lead to success. Today, several decades into the information age seems to be no […]
When brain and machines blend
A review of the book: The brain electric: The dramatic high-tech rage to merge minds and machines by Malcolm Gay
Flying cars, self-tying shoes or a fully functional hoverboard are only a few examples of the inventions which, according to […]
An acoustic quantum bus
At a fundamental level the term “quantum computing” implies de use of quantum effects that have no classical analogue to process information. In a “classical computer” information is held in bits, which can have two alternative values (0 and 1). […]
