Munchies and soft drinks will be served at 7:00 PM, the general meeting will start at 7:30 PM, followed by the program.

Abstract: Using Rational Rose RT with UML

Robert will present an example of using Rational Rose Real-Time models with the Unified Modeling Language to demonstrate socket interface techniques. Robert has also developed a Rose Real-Time Modeling Standard and associated coding standard in support of modeling efforts. Bob has also presented a series of Rose Real-Time demos and lectures showcasing different capabilities that may be implemented using the Rose Real-Time modeling tool.

Robert developed software with the Rational Rose Real-Time tool using the Unified Modeling Language for five vehicle-based subsystems. Robert developed a Rose Real-Time Modeling Standard and associated coding standard. As a Team Lead for a Software Safety Working Group performed Software Hazard Risk Assessment assigning Risk Indexes based on Mil-Std-882C and correlated with the standard software engineering Principles adopted from IEE12207/RTCA DO-178B based on Level A Catastrophic Level B Critical Hazardous, Level C Critical/Major, Level D Minor, Level E No influence. Robert also researched Software Safety Architectures depicting safety architectures using the Unified Modeling Language implementing techniques such as diverse and homogenous redundancy, and watchdog timers and software safety techniques such as partitioning and titanium wrappers.

Presenter: Robert O'Brien

Robert O'Brien has 15 plus years of technical experience in Space Systems, Air Traffic Control, Military Combat Systems, and Ground Data systems compliant to the SEI CMMI process model. He has performed many roles during this time, including lead software engineer, team mentor, process engineer, software quality engineer, software tester and software developer. Bob has significant experience with the Ada and C programming languages on various platforms including UNIX and Windows. He has several years of C++ experience as well as experience developing embedded real-time software subsystems using Rational Rose Real-Time.

Directions From Washington, DC

From the Capital Beltway (I-495),
1. Take the I-95 North exit;
2. Exit onto MD Route 32 West, at the Columbia exit (~ 10 miles);
3. Left onto U.S. Route 29 South at light (~ 2.5 miles)
4. Right onto Johns Hopkins Rd at light to go WEST (~ 1.5 miles) (There is now a new style dual-traffic circle overpass/interchange, which replaced the traffic light at this intersection. - Those travelling North on 29 from Silver Springs will be turning Right onto Johns Hopkins Road in order to make a logical Left turn to go WEST)
5. APL is located to the right, just past the service station;
6. Turn right at the sign: "Building 1 Visitor Parking";
7. Use Building 1 entrance near the flag-pole; The meeting is in the cafeteria.
