With virtual meetings on the rise in the age of coronavirus, there are plenty of things you can do to ensure your meetings go without a hitch. Miguel Tovar/University of Houston

Even in the pre-pandemic world, more employees were working remotely in America than ever before. Participating in virtual meetings is the norm, at least for now. The shift came rather abruptly. Millions of Americans had only a few days to make the transition. People are now working on laptops where before they worked on double-screen desktops. Home computers proved to be less convenient to work on since work computers have files and sites already organized for easy access. There are certain things that are more effectively communicated in person than through a screen.

But in 2020, there are myriad conferencing platforms that make it easier than ever to communicate virtually. From Skype and Zoom to Teams and Slack, there is no doubt that virtual work is more convenient than ever. Here are a few tips for how you can develop a personal and professional brand through virtual meetings.

Cast from a carpeted room

When you cast yourself from an empty room with tile or wood flooring, you might notice an echo in your audio. It can sound like you're in a cathedral. Carpeted rooms create much better audio quality. If you're not interested in having your whole room redone, lay down a nice carpet on your floor. This will significantly reduce the reverberation and create a sound that is full and intimate.

Opt for a neutral background

Instinctually, one might think that a shelf full of books, plants and photos might present a professional background. They'd be correct. However, in the interest of a virtual meeting, less is more. A neutral-colored wall such as gray or white would accentuate focus on you. It would keep the viewers' eyes from wandering. Trying to figure out what books you read, who that is in your photos, or judging you from your organizational method (or lack thereof).

Consider your lighting

A dimly lit room can convey a sense of, well, creepiness. Don't be creepy. You want to exude positivity. The best way to achieve this is through nice lighting. You want to make sure your desk has enough lighting on your face to bring out the clarity of it on screen. "I suggest using two LED lights at your desk with adjustable lighting on each side your computer camera. They should face toward you so you can adjust for daylight. Even a single lamp would help."

Use your computer over your phone

I know, this sounds like it should go without saying. But it needs to be said. There are too many people doing conference calls via phone. Your phone should be your absolute last resort in a situation where your computer is down and a meeting is absolutely urgent. Using a computer allows you to take notes and provides for a more stable picture. The audio and video quality is also leagues better on a computer.

Take a tech test

Sure, you can't completely get away with not having any technical issues. But what you can do is minimize the issues you're likely to have. Test your web conferencing program well before you are slated to log on. Be sure to grant all the appropriate permissions prior to logging on for the first time. This will save you tons of time as you continually log on every time afterward. Make sure the camera is set up correctly and that the audio works. If your microphone isn't hooked up to the program, connect it. The more testing you do with your web conferencing tech the less issues you'll have when it's finally time to virtually meet.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
