AI, ML and IoT Integrated Vertical Farming

Vertical farming is not a new concept, but recent technological advancements have made it more viable and efficient. This method leverages technology to grow crops indoors, often in skyscrapers, warehouses, or shipping containers, using vertically stacked trays to maximize space. The controlled environment agriculture (CEA) model underpins vertical farming, utilizing advanced technologies like artificial intelligence (AI), machine learning (ML), and the Internet of Things (IoT) to monitor and tailor growing conditions to the crops’ needs. The global community is facing mounting challenges to food security, particularly with the projected population reaching 10 billion by 2050. Traditional agricultural practices are increasingly constrained by issues such as land scarcity, water depletion, and

Defibrillator Medical Device

A defibrillator is a medical device designed to restore a normal heartbeat by sending an electric pulse or shock to the heart. It is commonly used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart’s beating if the heart suddenly stops. There are different types of defibrillators, including automated external defibrillators (AEDs), implantable cardioverter-defibrillators (ICDs), and wearable cardioverter-defibrillators (WCDs). AEDs are often found in public places and can be used by laypersons with minimal training. ICDs and WCDs are typically used for patients with a high risk of sudden cardiac arrest due to underlying

Top-Down vs. Bottom-Up Nanofabrication

What is Top-Down Nanofabrication? Top-down nanofabrication is a method in which bulk materials are progressively reduced to create nanoscale structures. This approach can be likened to a sculptor carving out a statue from a template by removing material, rather than building up from the atomic level. One of the most significant techniques within this method is photolithography, where short wavelength light or electrons (in the case of e-beam lithography) are used to pattern a photoresist. Subsequent etching processes, such as chemical, plasma, or reactive ion etching, then remove the material beneath the photoresist to form the desired nanostructure. Etching plays a crucial role in top-down nanofabrication. This process involves removing
