Archival storage Researchers at Harvard University and Northwestern University propose a method of long-lived archival data storage using low-weight molecules. DNA has been explored as a method of archival storage, but the researchers argue that it is inadequate, as the DNA macromolecule is large and requires skilled, repetitive labor to encode and read. Instead, the researchers turned... » read more

Internet of Things Verizon Communications launched its nationwide narrowband Internet of Things network, saying it covers more than 92% of the U.S. population. “There is a whole universe of smart solutions needing scalable and affordable connections,” Jeffrey Dietel, senior vice president of business marketing and products, said in a statement. “By launching our NB-IoT network, Verizon i... » read more

The Limits Of Energy Harvesting
By Ed Sperling and Kevin Fogarty - 09 May, 2019 - Comments: 4

Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

End-To-End Cell–Pack–System Solution: Rechargeable Lithium-Ion Battery
By Ansys - 08 May, 2019 - Comments: 0

Industry has become more interested in developing optimal energy storage systems as a result of increasing gasoline prices and environmental concerns. A major application for energy storage use is hybrid electric vehicles (HEVs) and electric vehicles (EVs). The rechargeable energy storage system is a key design issue, as it dominates overall vehicle performance. The system as a whole must deliv... » read more

Internet of Things Combining artificial intelligence with unmanned aerial vehicles could provide a quicker and safer alternative to inspecting roadways for cracks, potholes, and other damage, according to a paper posted on arvix.org. “[M]anual visual inspection [is] not only tedious, time-consuming, and costly, but also dangerous for the personnel. Furthermore, the detection results are alwa... » read more

Predicting battery life Researchers at Stanford University, MIT, and Toyota Research Institute developed a machine learning model that can predict how long a lithium-ion battery can be expected to perform. The researchers' model was trained on a few hundred million data points of batteries charging and discharging. The dataset consists of 124 commercial lithium iron phosphate/graphite cells... » read more

Power/Performance Bits: Feb. 5
