The Birth of Random-Access Memory

The Birth of Random-Access Memory

Whether you’re streaming a movie on Netflix, playing a video game, or just looking at digital photos, your computer is regularly dipping into its memory for instructions. Without random-access memory, a computer today can’t even boot up.Over the years, memory has been made up of vacuum tubes, glass tubes filled with mercury and, most recently, semiconductors.But the first computers didn’t have any reprogrammable memory at all. Until the late 1940s, every time a machine needed to change tasks, it had…

3D snapshot sensor for 3D measurements and surface inspection of large objects

Large, diffuse reflecting objects of up to 650 x 495 mm are measured using the surfaceCONTROL 3D 2500 snapshot sensor. The sensor is based on the fringe light projection principle to perform geometrical 3D measurements and 3D shape detection, as well as surface inspections. It can be used both withi Source: Micro-epsilon…

Radar Technology Pioneer Merrill Skolnik Dies at 94

Radar Technology Pioneer Merrill Skolnik Dies at 94

Merrill SkolnikFirst recipient of the IEEE Dennis J. Picard MedalLife Fellow, 94; died 27 January
Skolnik served as superintendent of the radar division of the U.S. Naval Research Laboratory in Washington, D.C., for more than 30 years. While there, he made significant contributions including helping to develop high-frequency, over-the-horizon radar; a system that can identify friend or foe during combat; and high-resolution radar techniques.
For his work in the field, he was named the first recipient of the IEEE Dennis J. Picard Medal…

Scientists achieve record efficiency for ultra-thin solar panels

A team has successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometer thick, convert light into electricity more efficiently than others as thin and pave the way to make it easier to general more clean, green energy.

AI Could Help Increase the IVF Success Rate

AI Could Help Increase the IVF Success Rate

More than 8 million people have been born worldwide with the help of in vitro fertilization since 1978. In IVF, an egg is fertilized by sperm in the lab; the resulting clump of cells is transferred into a patient’s uterus.Although IVF techniques have advanced significantly in recent decades, the average success rate is still fairly low: around 45 percent. The percentage steadily declines as women age; a 40-year-old woman has a likely success rate of about 12 percent, according to Pregnancy…

Stories of the War in Ukraine: Volodymyr

Stories of the War in Ukraine: Volodymyr

Over the past week, The Institute has made contact with some of the 400 members of the IEEE Ukraine Section to help them share their experiences during the war. This personal account was written by Volodymyr Pyliavskyi, a senior researcher at the Odessa National Telecommunications Academy in Odessa, Ukraine. “For so long I was planning to take part in IEEE conferences but due to what is happening I can’t,” Pyliavskyi told The Institute. “I am forced to to hide in the…

Explore Resources During IEEE Education Week

Explore Resources During IEEE Education Week

Education is changing fundamentally. STEM workforce shortages and a push for more diverse hiring practices have created opportunities for students and workforce professionals to explore science, technology, engineering, and math careers that might not have been available even 10 years ago. IEEE and other education providers are working to offer foundational STEM learning experiences, as well as the reskilling and upskilling opportunities required to support the workforce of the future.At the preuniversity level, students have both in-class and extracurricular opportunities to…

Materials scientists finding solutions to biggest hurdle for solar cell technology

Materials scientists have discovered the major reason why perovskite solar cells — which show great promise for improved energy-conversion efficiency — degrade in sunlight, causing their performance to suffer over time. The team successfully demonstrated a simple manufacturing adjustment to fix the cause of the degradation, clearing the biggest hurdle toward the widespread adoption of the thin-film solar cell technology.

Optimizer tool designs, evaluates, maximizes solar-powered cooling systems

Researchers have developed an optimizer tool to design, evaluate, and maximize the performance of different types of solar-powered adsorption under various operating scenarios. The tool was created using Visual Basic programming language that is easy to learn and enables rapid application development and predicted the proper material mass concentration ratios. The method calculated the cooling load, predicted maximal performance, and conducted the overall performance analysis of the cooling system. Source: Solar Energy News — ScienceDaily …
