  Power Electronics in Smart Grid The biggest technological revolution in the last decade is “Smart Grid”. As compared to the conventional grid, smart grid is automated, highly integrated, technology driven and modernised grid. In coming years smart grid will have a key role in transforming the electrical networks, its topology and power system operation. Energy efficiency, electricity supply and sustainability are the foundation pillars of smart grid technology. The reliability of electric supply has become the utmost priority of consumers in developed as well as developing countries throughout the world. Through smart grid implementation, monitoring, control and real time measurement of generation, transmission and distribution of electrical energy has become possible and hence reliability of electric supply is improved. Smart grid has the potential to reduce the carbon footprints by integration of renewable energy sources, energy storage and plug-in hybrid electric vehicles with...

 3D bioprinting describes the use of 3D-printing techniques to combine cells, growth factors (proteins or hormones) and biomaterials to create biomedical parts that precisely imitate natural tissue characteristics. This technology utilises a layer-by-layer method to deposit materials called bioinks and creates tissue-like structures that can later be used in the fields of medical and tissue engineering. Though this application of three-dimensional printing is in its infancy, Israeli scientists have already created the world’s first 3D-printed heart using human cells. While this artificial heart doesn’t beat and is only the size of a rabbit’s, it represents a significant step in the ongoing efforts to improve treatment for heart disease — one of the biggest killers in the Western world. 3D bioprinting’s potential is enormous. In the near future, doctors may have the ability to print artificial skin cells for burn wound victims.

  Delta  has announced its new EV charging management system, Delta Grid EVM, an innovative platform featuring artificial intelligence (AI) capabilities and seamless integration with energy infrastructure (solar energy and energy storage), is enhancing the power stability and operating efficiency of EV charging sites across the world. Electrical safety, billing, and day-to-day management are critical issues to support the rapid growth of EV charging infrastructure in residential and commercial buildings since most buildings did not conceived the capacity for setting up chargers at the time of construction. A scheduling system powered by an AI model prevents exceed demand contract or overloading, allowing existing buildings to provide charging services without significant renovation. Delta Grid EVM is also the leading solution in the industry to incorporate EV charging, solar energy and energy storage into a single platform. Since its launch, Delta Grid EVM has not only added v...

  A Supervisory Control and Data Acquisition (SCADA) system is  an enterprise-level software whose main task is to monitor and control an electrical grid system based on the information it collects from the substations within that system . SCADA systems are mainly used for the implementa tion of monitoring and control system of an equipment or a plant in several industries like power plants, oil and gas refining, water and waste control, telecommunications . Components of Typical SCADA System The major components in SCADA system are Remote Terminal Units (RTUs)   RTU is the main component in SCADA system that has a direct connection with various sensors, meters and actuators associated with a control environment.  These RTUs are nothing but real-time  programmable logic controllers (PLCs)  which are responsible for properly converting remote station information to digital form for modem to transmit the data and also converts the received signals from ma...

 Brain-computer interfaces (BCIs) are devices that enable signals from the brain to direct external activity, such as moving a cursor or prosthetic limb. BCIs work by measuring the brain’s electrical activity using a monitoring method called electroencephalography (EEG), which involves placing electrodes on the scalp surface. For individuals who have experienced a debilitating loss of motor control, the pursuit of this assistive technology by researchers offers a crucial ray of hope. Though brain-to-computer technology may sound futuristic, the first human to be successfully implanted with a BCI was way back in 2004, when a quadriplegic named Matthew Nagle received a device called BrainGate that allowed him to move a cursor across a screen. Since that momentous moment, the capabilities of modern BCIs have advanced to such an extent that a number of ethical questions have been raised, ranging from privacy to loss of humanity. For example, if a BCI device misreads an invasive thought...

  An electric traction system is  the type of traction system that uses electrical energy for the movement of vehicle at any stage .  The electric traction system is classified into two groups as − Self-contained vehicles or locomotives  An  electric traction system  is the type of traction system that uses electrical energy for the movement of vehicle at any stage. The electric traction system is classified into two groups as − Self-contained vehicles or locomotives (Ex. – battery-electric drive and diesel-electric drive) Vehicles or locomotives which receive electric power from a distribution network or suitably placed substations (Ex. - railway electric locomotives, tramways and trolleybuses, etc.) Here, we described different  types of electric traction systems  along with their advantages and disadvantages  Straight Electric Traction System In the straight electric traction system, either DC series motor or single phase AC series motor o...

 Nanorobotics is an emerging field of technology that involves creating tiny surgical robots whose components are roughly the size of a nanometre (equivalent to one-billionth of a metre or one-millionth the length of an ant). With their microscopic size, these burgeoning technologies will enable scientists to manipulate biological matter at an atomic or molecular level — with seismic implications for our ability to effectively fight diseases. In surgery, medical nanobots will be introduced into the body in a minimally invasive way via the vascular system or other cavities. Programmed or directed by a human surgeon, they would perform crucial functions such as searching for pathogens. Because nanobots are capable of recording vital signs such as temperature and blood pressure, it’s thought this technique will enable doctors to diagnose, test and monitor microorganisms, tissues and cells in the bloodstream. Nanotechnological innovation in healthcare recently had a huge breakthrough: ...

  New customized P47 sensor variant from PiL for ultrasonic level and distance measurement in robust stainless steel housing with optional deflection angle With a new model variant of the proven sensor series P47,  PiL Sensoren GmbH  underlines its flexibility in the development of customized special solutions. The high-precision ultrasonic sensors are predestined for basic applications such as distance and level measurements in the measuring range up to 5,000mm and ensure reliable detection of even small objects due to their sound intensity. For demanding industrial applications with limited installation space, PiL has now produced a special version of the sensor for distances from 50mm to 500mm at the request of a customer. Instead of the conventional plastic housing, this sensor variant is equipped with a robust M18 stainless steel housing as well as a 90° deflection angle and complete shielding. The manufacturer offers the ultra sonic device optionally with fixed or c...

                                               Energy storage analysis sustainable infrastructure and the future of energy storage Sustainability agenda-driven changes at an industrial scale are probably most visible in the transition of the energy sector. In view of this, the power system of the future is unlikely to be solely reliant on infrastructure that spins up in faraway power stations in response to demand for electricity. Solar and wind energy, captured and turned into electricity when the sun shines and when the wind blows will be stored until is it needed. And energy storage is going to be pushed to the edge of the network. Interest and investment in energy storage is rising. Some systems being proposed are new and some based on existing (and in the case of kinetic energy, ancient) technologies. Many may be small in scale, but some of tho...
