The symmetric difference (disjunctive union/disunion) of sets A and B (A ^ B) is the set of all elements that are in set A or in set B but not both. Symmetric difference is also commutative, meaning A ^ B == B ^ A.
The difference (subtraction) of sets A and B (A – B) is the set of all elements that are in set A and not in set B. Subtraction is not commutative meaning A – B != B – A.
The intersection of sets A and B (A ∩ B) is the set of all elements that are contained in both A and B. Note again that the result is still a set (no duplicates). Intersection is also commutative, meaning A ∩ B == B ∩ A.
A set is a collection of elements in which there are no duplicates. The union of sets A and B (A ∪ B or A + B) is the set of all elements that are contained in either A or B (or both). Note that the result is still a set (no duplicates) even if an element is in both A

We are happy to welcome Ezra, son of Levi, as the most recent addition to the One Fact team and the xtUML modeling community. He was born January 21 weighing 7 pounds 1 ounce and 21 inches long.
The BridgePoint development team communicates every day using messaging apps. We have one messaging channel open to the entire community. It was on skype for a few years. Recent changes to skype in combination with improvements to google hangouts have caused us to decide to move this community chat to google hangouts. Join the conversation

MT-CPS’18 3d International Workshop on Monitoring and Testing of Cyber-Physical Systems Porto, Portugal, USA 10 April 2018 Co-located with CPS Week https://sites.google.com/asu.edu/mtcps2018 DESCRIPTION Cyber-physical systems (CPS) are integrations of heterogeneous collaborative entities that interact among themselves and with their physical environment. CPS exhibit complex and unpredictable behaviors, thus making their correctness and robustness analysis a

The presentations from xtUML Day in Linköping in October have been published on xtuml.org (here).
Sometimes it is good to relax, enjoy the Autumn weather and reconnect with colleagues. Our dear friend and long-time BridgePoint engineer, Heba, visited 1F headquarters from Cairo, Egypt. We enjoyed a distinctly Indiana experience at a farm and wandered through an 18 acre corn maze.
