The Ptolemy project studies modeling, simulation, and design of concurrent, real-time, embedded systems. The focus is on assembly of concurrent components. The key underlying principle in the project is the use of well-defined models of computation that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation. A software system called Ptolemy II is being constructed in Java. The work is conducted in the Industrial Cyber-Physical Systems Center (iCyPhy) in the Department of Electrical Engineering and Computer Sciences of the University of California at Berkeley. The project is directed by Prof. Edward Lee. The project is named after Claudius Ptolemaeus, the second century Greek astronomer, mathematician, and geographer.

- Reactors: This effort is developing polyglot metalanguage for composing reactors, concurrent components that exchange timestamped messages. This language is intended for distributed systems, particularly those with time-sensitive behavior. See the Lingua Franca GitHub repository and Wiki.
- Cyber-physical systems: Models of computation with time and concurrency, metaprogramming techniques, code generation and optimization, domain-specific languages, schedulability analysis, programming of sensor networks. See the iCyPhy (industrial cyber-physical systems) consortium and early position paper and publications page for elaborations.
- Understandable concurrency: This effort focuses on models of concurrency in software that are more understandable and analyzable than the prevailing abstractions based on threads. See a 免费npv加速器官网.
- Systems of systems: This effort focuses on modeling and design of large scale systems, those that include networking, database, grid computing, and information subsystems. See for example the Kepler project, which is a scientific workflow management system.
- Semantics: Domain polymorphism, behavioral type systems, meta-modeling of semantics, comparative models of computation. See papers on semantics.
- Hybrid systems: Blended continuous and discrete dynamics, models of time, operational semantics, language design. See the paper on hybrid systems semantics and paper on semantics of mixed continuous and discrete systems.

The bioKepler suite facilitates rapid development and scalable
distributed execution of bioinformatics workflows in Kepler while
simplifying access to a wide range of bioinformatics tools executed
locally or distributedly. bioKepler 1.0 contains a set of Kepler
actors, called "bioActors", which are specialized for running
bioinformatics tools along with Kepler directors for distributed
data-parallel (DDP) execution on Hadoop and Stratosphere engines.
Additionally, over 40 example workflows demonstrating how to use these
actors and directors have been packaged in this first release of
bioKepler.
Kepler uses Ptolemy II as its execution engine. - April 28, 2013: jfmi1.0.2, a Java Wrapper for the Functional Mock-up Interface was released.

"As members of the AY09-10 MSE YALA Studio Team, Yousef AlSaeed, Ashwini Bijwe, Lyle Holsinger, and Wenjiao Wang not only acknowledged their individual cultural differences, they benefited from them. Demonstrating strong commitment, support, and personal affection for one another, they worked deliberately, cohesively for the greater team goals, yet rarely missed opportunities to recreate and enjoy each other's company socially. This extraordinary team exemplified the very essence of professionalism, collaboration, and mutually-respectful partnership."
