Abstract. In this paper, we present a method for developing Java applications from Colored Control Flow Nets (CCFNs), which is a special kind of Colored Petri Nets (CPNs) that we introduce. CCFN makes an explicit distinction between the representation of: The system, the environment of the system

the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them. They provide bias signals to other brain structures whose net effect is to guide the flow of activity along neural pathways that establish the proper mappings between inputs, internal

I analyze financing policies in a firm owned by atomistic shareholders who observe neither cash flows nor management’s investment decisions. Management derives perquisites from investment and invests as much as possible. Since it always claims that cash flow is too low to fund all positive net

Petrify is a tool for (1) manipulating concurrent specifications and (2) synthesis and optimization of asynchronous control circuits. Given a Petri Net (PN), a Signal Transition Graph (STG), or a Transition System (TS) 1 it (1) generates another PN or STG which is simpler than the original

Using NetScope, a network provider can experiment with changes in network configuration in a simulated environment, rather than the operational network. In addition, the tool provides a sound framework for additional modules for network

queries. Compared to Fagin's algorithm we have developed an improved termination condition in tuned combination with a heuristic control flow adopting itself narrowly to the particular score distribution. Top-ranked results can be computed and output incrementally. We show that we can

patterns and provides a formal description of each of them in the form of a Coloured Petri-Net (CPN) model. It also identifies twenty three new patterns relevant to the control-flow perspective. Detailed context conditions and evaluation criteria are presented for each pattern and their implementation

and documented them in the pattern format. The patterns focus on the interplay between data-flow and control-flow, (i.e. the essence of Colored Petri Nets), and have been modeled using CPN Tools. The goal of the patterns is to assist and train inexperienced modelers, and to serve as a domain language

Access control mechanisms are often used with the intent of enforcing confidentiality and integrity policies, but few rigorous connections have been made between information flow and runtime access control. The Java virtual machine and the .NET runtime system provide a dynamic access control
