Boeing Technical Fellow to Discuss Boomerang Aerodynamics

Boeing Technical Fellow John Vassberg will discuss the aerodynamic characteristics and flight dynamics of boomerangs at the Spring Technical Seminar at noon on Friday, Feb. 23 in the Niggli Conference Center (ECS-312). Students and faculty are invited to attend.

Dr. Vassberg will explain how blade theory can be used to expand upon a basic aerodynamic model developed in the 1960s. The new aerodynamic model is coupled with a gyroscope model for rudimentary analyses. The approach has generated significant findings regarding the radius of a boomerang’s circular flight path, the required inclination angle of its axis-of-rotation, its trim state, as well as its dynamic stability. These discoveries provide a basic understanding of how the interplay between aerodynamic forces and moments, and gyroscopic precession combine to return the boomerang to its rightful owner by way of a circular flight path.

Dr. Vassberg is Technical Lead and Chief Aerodynamicist of BCA Advanced Concepts Design Center in Southern California. He is a Boeing Technical Fellow, an AIAA Fellow, and recipient of the AIAA Aerodynamics Award in 2012 and the International Cooperation Award in 2017.

Prior to his current position, he was Chief Aerodynamicist of Boeing’s Research & Technology organization, and Principal Investigator of the Advanced Joint Air Combat System (AJACS), Speed-Agile Configuration Development (SACD) and Over-Wing Nacelle (OWN) programs. The SACD Program received the 2013 Aviation Week Laureate Award in Aero and Propulsion.

Dr. Vassberg received his PhD from the University of Southern California in 1992, and his MS and BS from Texas A&M University in 1981 and 1980, respectively, all in Aerospace Engineering.

Data Privacy Technique Discussed at IEEE Distinguished Lecture Series

If you’d like to send a private Valentine to that special someone this month, Spatial Digital Systems can help.

The Agoura Hills-based company has come up with a technique to embed your message within a separate, innocuous message to shield it from prying eyes. Donald Chang, Spatial Digital Systems’ CEO and President, demonstrated the technique before faculty and students at the IEEE Systems’ Council’s IEEE Distinguished Lecture Friday.

Called “digital enveloping,” the technique can be used to wrap a Microsoft Word document in an audio file or a real-time voice recording in an audio file. Sender and receiver would both know the technique was being used.

In Friday’s demo, the company used audio files of Chinese opera to envelop the actual message. “Like in the marketplace, there’s a lot of noise,” said Spatial Digital Senior Engineer Joe Lee. “You would not suspect there’s a message hiding inside.”

The technique could be useful for ensuring better privacy protection for data in the cloud. As the company describes it, digital enveloping relates to “transforming” an information data stream with a digital envelope stream concurrently into a multi-dimensional data structure via Wavefront multiplexing (WF muxing, K-muxing).

Top priorities are the appearance of the enveloped data and the reliability of the enclosed information data. The transformation is mathematically identical to the function of a beamforming network (BFN) for a multibeam phased array.

Spatial Digital Systems was formed in 2002 to develop smart antenna technologies for wireless communications. Chang is an expert on communications satellites, advanced satellite antennas, space-based microwave remote sensing instruments, especially in passive synthetic aperture radiometry. He has authored more than 40 technical papers, holds more than 100 U.S. patents, and has more than 50 U.S. patents pending on smart antennas, low cost spacecraft design, and satellite constellations for multimedia applications.

Chang was the recipient of Hughes’ Hyland Award in 2000 for key contributions in digital beam-forming technology. He holds a PhD and MSEE from Stanford University.

How Automation Is Changing the World, and the Workforce

At transportation terminals, automation is boosting productivity and creating safer work environments. In the medical device industry, it’s advancing product development and letting employees learn new technologies. And in aerospace, it’s leading to new manufacturing processes and a future age of autonomous aircraft.

At Thursday’s Fall Engineering Distinguished Lecture, representatives from all three industries shared how automation is changing the world—and the workforce.

“This is one of those topics that is very pertinent—automation, robotics, artificial intelligence—all the things we live with today,” said moderator Rolando Saldana, vice president of engineering at Qualcomm. “Going forward, we’re also seeing that industry is moving forward with automation. And these (speakers) are the folks who are putting together the systems.” Continue reading

Female Faculty Share their Stories

They each had a story of how they got here. An early interest in science. The influence of family members or mentors. Even a random selection in an academic catalogue.

But the CSULB female engineering faculty who shared their backgrounds with Society of Women Engineers members all had one thing in common: a passion for research.

Civil engineering Assistant Professor Pitiporn Asvapathanagul’s path included a stint working in her family’s Thai restaurant. She’d earned her undergraduate degree in environmental engineering in Thailand when her family beckoned her to move to the U.S.

Eventually, her desire to return to engineering led her to earn a master’s degree and doctorate from University of California Irvine. At CSULB since 2012, Asvapathanagul is an expert in biological water reclamation. Continue reading

CECS Introducing Colloquium Series

The Long Beach State Department of Computer Engineering and Computer Science this semester will be launching a Colloquium Series to provide a forum for industry best practices and to make research more tangible for students.

Each semester, there will be 4-5 talks by invited speakers from academia and industry, said CECS Assistant Professor Birgit Penzenstadler.

The first talk will be on Thursday, Sept 28 from 12:30-2 p.m. in VEC-110. It will feature Ph.D. candidate Jayden Khakurel, who will discuss Human-centered Design and Wearables. Continue reading

EE Remembers Lecturer Boi Tran

At its Department Graduation Monday, the CSULB Electrical Engineering Department commemorated lecturer Boi Tran’s supportive mentoring with an award in his name. Chris Hirunthanakorn (BSEE) received the Boi Tran Award, in memory of the late electrical engineering lecturer, who passed away suddenly late last year.

“It’s my honor that I’ve met and worked with Boi Tran, whose untimely passing has left a hole in our collective soul,” said Professor Anastasios Chassiakos, who described Tran as not only a very talented engineer but a trusted friend and mentor. Tran’s wife, Mindy, was present to accept the award.

Another of the department’s awards is named for the late Gerald Doski, an ever-helpful technician. The Doski Award this year went to Scott Salazar. Continue reading

MAE Department Salutes Its Alumni, Volunteers, and Graduates

Xerox VP Arnold Hackett Named CECS Distinguished Alumni

Arnold Hackett was one of nine children raised by a single parent. He is now vice president of alliance and partnership management at Xerox.

The 2001 CSULB computer science graduate said he has Xerox to thank—and also CSULB. “They helped me become what I am today,” he told students at the CECS Department Graduation.

Hackett, who earned his master’s in computer science while working at Xerox, on Monday received the CECS Distinguished Alumni Award. He was also named the Alumni Association’s College of Engineering 2017 Distinguished Alumni Award.

Hackett said a degree in computing is very powerful. “You’ve been given the tools to create and innovate and make your dreams a reality,” he said. Continue reading
