Software Architecture UML Component Diagram

We applied object-oriented analysis and design techniques, using the Unified Modeling Language (UML) as the design and communication tool. • Analysis & Design: − Developing a solution using the

UML component model and sequence diagram to design the architecture and model the communication requirements between the components. • Implementation: − Implementing of the software system that authorizes user access based on time and location.

TAMIU students work to transform Texas through undergraduate research

Three students from Texas A&M International University (TAMIU) made their mark during the online research day held Feb. 23–24. This year's theme, "Transforming Texas Through Undergraduate Research," highlighted students' work engaged in research for Texas legislators and how it impacts the state.

Marshal Moncivais, Miguelangel Treviño,

and Carlos Delgado submitted their poster "Software for Incorporating Time and Location into Access Control Decisions" under Dr. Mustafa Al Lail, an assistant professor of computer science and engineering, School of Engineering. The virtual presentation described an increasing dependency on digital technology, the importance of data security, and a model using software development technologies. "I congratulate our students on their selection for this statewide research recognition," said TAMIU president Dr. Pablo Arenaz. "This type of facultystudent research collaboration is a distinction of our undergraduate program. These opportunities are a core element in our strategic plan that focuses on creating a transdisciplinary and collaborative research environment that fosters discovery, educates our students and community, and generates substantive solutions for a changing global society."

decades ago, HACU has grown from 18 charter members to 500-plus member institutions. Dr. Antonio R. Flores has led HACU for the last 25 years. During his tenure, he has helped the association increase federal funding for Hispanic-serving institutions (HSIs). More than $4 billion has been allocated to them over the years, according to HACU. Additionally, HACU's National Internship Program has made over 13,000 internship placements since its inception. "Tremendous progress has been made through the years to serve Hispanics in higher education, but as more Hispanic-Serving Institutions emerge, so too does the need to advocate for improved funding support for HSIs," Flores said.

Juntos perseveramos (Together we persevere): NASA's first planetary landing with an official transmission in Spanish

On Feb. 18, Diana Trujillo hosted the first-ever Spanish-language NASA transmission of a planetary landing for the Perseverance rover. Trujillo, who came to America at 17 with only $300, is currently flight director for Mars 2020 Perseverance. "Here at NASA, I have many friends from Mexico, Puerto Rico, Cuba, Spain, and other countries, but we need more Latinos to accompany us on the missions to come," said the aerospace engineer at the NASA Jet Propulsion Laboratory. The Spanish-language NASA transmission included a video with middle school girls who shared their dreams of becoming engineers, spacesuit designers, rocket builders, and astronauts on missions to Mars. "We want to say to Latinas who are interested in pursuing space sciences that here we are, here is Diana, here I am. We are many, willing to connect with you, in serving as mentors, in putting this community bond that all Latinos have to connect with. We are here to encourage you and encourage us to fulfill our goals and dreams," said Yajaira Sierra-Sastre, a materials science and nanotechnology scientist. She dreams of being the first Puerto Rican astronaut. Recently, Sierra-Sastre was selected to be part of a simulated mission to Mars. "In a decade, when those samples that Perseverance is going to collect return to Earth, it will be many of the boys and girls who look at us today, geologists, biologists, or physicists who must analyze them," she added.
