Row-level airflow management refers to improving cold aisle and hot aisle separation. It’s typically done once you’ve made improvements at the rack level (e.g. blanking panels) and raised floor level (e.g. brush grommets). When we talk to data center operators about improving airflow efficiency at the row, they’ll jump ahead to containment a little too quickly. The fact is, there are several areas in the row that can be addressed without engaging in a full-blown containment initiative.
As disruptive forces transform the power and utilities sector, many companies are turning to digital technologies and a more innovative mindset to thrive in the new era. Those that don’t seize the opportunity to evolve risk being left behind or displaced by more agile players.
Multifamily is just seeing the beginning of the impact that IoT will have, and second generation solutions will bring significant benefits to property owners, managers and maintenance staff. Three trends include smarter security systems, healthier environments, and improved response time from property managers and maintenance staff.
While the benefits and Return on Investment (ROI) of smart buildings are well documented for tenants, building owners and operators, similar information for cities are limited at best. In addition, cities measure the benefits and ROI of smart buildings differently, and look beyond financial metrics. Part One of this two part article provides an understanding of the types of things that cities care about, and leads to a new set of metrics for evaluating the ROI of smart buildings.
Wavefront shaping has revolutionized the spatial control of coherent light beams thanks to the use of spatial light modulators (SLM) in disordered systems such as biological tissue, white paint or multimode fibers. Different approaches have been developed to control the propagation of coherent light that has experienced scattering, such as iterative optimization, optical phase conjugation, and the measurement of the optical transmission matrix.
Listed here are statements from providers of products and services to the information and communications technology (ICT) industry, about their business-continuity status amid the COVID-19 pandemic. The list is in alphabetical order. We’ll update it as we become aware of changes or additions.
Expanded beam connectors have a high tolerance for dirt and debris, but EB fiber optic systems are not immune to contamination. They should be cleaned routinely but standard fiber optic cleaning tools simply will not work. The CleanStixx™ EB swab can clean 1.2mm and larger EB connectors. The porous, thermally-sintered, variable-density polymer tip fits over the lens of the EB connector and removes dust, liquids and finger prints delivering a fast, reliable fiber optic network
To handle higher bandwidth, improve network density, and prepare for future upgrades, more data center designers and network managers are moving to multi-fiber push-on connections or MPOs in their fiber network infrastructure. This White Paper provides an overview of all things MPO, including fiber counts, color coding, cleaning, and polarity considerations.
NASA uses simulation software to design spacecraft, predict satellite orbits, and train astronauts. But modeling and simulation are powerful tools that can generate valuable information anywhere they can be applied. In the early 2010s, a group at the Jet Propulsion Laboratory (JPL) successfully used simulation software to model the data transmissions, storage, and processing within and among all the sub-systems on a hypothetical spacecraft. The team wanted to predict the performance of a possible replacement for outdated, inefficient spacecraft data networks.
