Little Screen, Big Document

Yes, you can read through piles of long documents on your little smartphone. It can be a painful experience, however, particularly if you’re trying to do more than read straight through—browsing, skimming, and annotating are particularly tough. But admit it—you’d really like to take all your reading with you on your smartphone or pad computer. So we have good news for you: Help is coming. Here are three things that will soon make reading big documents on small devices a little less painful. (And you can see more here, here and here.)

Smaller, Cheaper Flow Batteries Throw Out Decades-Old Designs

A new approach holds promise for storing intermittent renewable energy at scale

Liu’s lab in the School of Chemical and Biomolecular Engineering (ChBE) developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery.

Georgia Institute of Technology

By replacing the traditionally flat electrodes and membranes in a flow battery cell with wire electrodes and tubular membranes, researchers have shrunk the battery cell size by 75 percent. This reduction in footprint and complexity could cut the cost of flow batteries, an important front-runner to store renewable energy on the grid.

Solar and wind power are growing faster than ever, according to the International Energy Agency. Making these intermittent energy sources a regular part of the grid without causing instabilities will require batteries to store energy on a large scale.

Flow batteries are a promising technology for that. Unlike lithium-ion batteries, which store energy in solid electrodes, flow batteries store chemical energy in liquid electrolytes that sit in tanks. This stored charge is converted into an electric current (and vice versa) in a power module, which is a stack of electrochemical cells.

Learn How Global Configuration Management and IBM CLM Work Together

In this presentation we will build the case for component-based requirements management

To fully support Requirements Management (RM) best practices, a tool needs to support traceability, versioning, reuse, and Product Line Engineering (PLE). This is especially true when designing large complex systems or systems that follow standards and regulations. Most modern requirement tools do a decent job of capturing requirements and related metadata. Some tools also support rudimentary mechanisms for baselining and traceability capabilities (“linking” requirements). The earlier versions of IBM DOORS Next supported a rich configurable traceability and even a rudimentary form of reuse. DOORS Next became a complete solution for managing requirements a few years ago when IBM invented and implemented Global Configuration Management (GCM) as part of its Engineering Lifecycle Management (ELM, formerly known as Collaborative Lifecycle Management or simply CLM) suite of integrated tools. On the surface, it seems that GCM just provides versioning capability, but it is so much more than that. GCM arms product/system development organizations with support for advanced requirement reuse, traceability that supports versioning, release management and variant management. It is also possible to manage collections of related Application Lifecycle Management (ALM) and Systems Engineering artifacts in a single configuration.
