The hierarchical system of distributed objects work control

The common attribute of the geo-distributed systems (GS) is the way of their organization. The structure of GS is usually an up-down depended hierarchy where the processes of their inter work control are implemented as two sides (up-down, down-up) information exchange. As a result, the subcomponents of typical GS are in some distance from each other. The main clue of GS manager is the quality of information process flow and a medium of data exchange. The state of art of data describes technologies, e.g. XML (eXtensible Markup Language) [1, 2, 3] and the progress of the Internet interoperabilitation, especially in Web Services [4], gives for the designers some new opportunities of application design. In this way, the layer of data interchange of GS subcomponents will migrate to the next/new level of abstraction. Its consequence is ability of reorganization of the controlled object structures and modelling of dimensions extends.This article presents a model of hierarchical system of distributed objects work control (HCS). The model is based on a cube of data repository and dedicated web serviced methods. This model is used in the investigations of the electric energy consumption control by the author

BDEF : the behavioral design data exchange format

BDDB is a Behavioral Design Data Base that manages the design data produced and consumed by different behavioral synthesis tools. These different design tools retrieve design data from BDDB, manipulate the data, and then store the results back into the data base. BDDB thus needs to address the following two issues: (1) a design data exchange approach and (2) customized design data interfaces. To address the first issue, we have developed a textual description format for describing design data objects and relationships. This language, referred to as the Behavioral Design Data Exchange Format (BDEF), is used as common format for exchanging design data between BDDB and the design tools in the behavioral synthesis environment. To address the second issue, we have developed a behavioral object type description language (generally referred to as schema definition language) for describing the global data structures required by design tools as well as the desired design subviews of this global BDDB design information. One design view class, namely, BDEF, is the topic of this report.In this report we give a formal definition of the BDEF format. Then we describe a comprehensive example of applying BDEF to the behavioral synthesis domain. That is, we present the complete BDEF syntax for the Extended Control/Data Flow Graph Model (ECDFG), which is the design representation model used by most behavioral synthesis tools in the UCI CADLAB synthesis system. We also present several example descriptions of designs using this ECDFG model. A parser/graph compiler from BDEF into the generalized ECDFG design representation as well as a BDEF generator from the ECDFG data structures into the BDEF format have been implemented

BINet: Multi-perspective Business Process Anomaly Classification

In this paper, we introduce BINet, a neural network architecture for real-time multi-perspective anomaly detection in business process event logs. BINet is designed to handle both the control flow and the data perspective of a business process. Additionally, we propose a set of heuristics for setting the threshold of an anomaly detection algorithm automatically. We demonstrate that BINet can be used to detect anomalies in event logs not only on a case level but also on event attribute level. Finally, we demonstrate that a simple set of rules can be used to utilize the output of BINet for anomaly classification. We compare BINet to eight other state-of-the-art anomaly detection algorithms and evaluate their performance on an elaborate data corpus of 29 synthetic and 15 real-life event logs. BINet outperforms all other methods both on the synthetic as well as on the real-life datasets

Discrete event simulation tool for analysis of qualitative models of continuous processing systems

An artificial intelligence design and qualitative modeling tool is disclosed for creating computer models and simulating continuous activities, functions, and/or behavior using developed discrete event techniques. Conveniently, the tool is organized in four modules: library design module, model construction module, simulation module, and experimentation and analysis. The library design module supports the building of library knowledge including component classes and elements pertinent to a particular domain of continuous activities, functions, and behavior being modeled. The continuous behavior is defined discretely with respect to invocation statements, effect statements, and time delays. The functionality of the components is defined in terms of variable cluster instances, independent processes, and modes, further defined in terms of mode transition processes and mode dependent processes. Model construction utilizes the hierarchy of libraries and connects them with appropriate relations. The simulation executes a specialized initialization routine and executes events in a manner that includes selective inherency of characteristics through a time and event schema until the event queue in the simulator is emptied. The experimentation and analysis module supports analysis through the generation of appropriate log files and graphics developments and includes the ability of log file comparisons

Translating semantic web service based business process models

We describe a model-driven translation approach between Semantic Web Service based business process models in the context of the SUPER project. In SUPER we provide a set of business process ontologies for enabling access to the business process space inside the organisation at the semantic level. One major task in this context is to handle the translations between the provided ontologies in order to navigate from different views at the business level to the IT view at the execution level. In this paper we present the results of our translation approach, which transforms instances of BPMO to instances of sBPEL

VSS : a VHDL synthesis system

This report describes a register transfer synthesis system that allows a designer to interact with the design process. The designer can modify the compiled design by changing the input description, selecting optimization and mapping strategies, or graphically changing the generated design schematic. The VHDL language is used for input and output descriptions. An intermediate representation which incorporates signal typing and component attributes simplifies compilation and facilitates design optimization. The compilation process consists of two phases. First, a design composed of generic components is synthesized from the input description. Second, this design is translated into components from a particular library by a mapper and optimized by a logic optimizer. Redesign to new technologies can be accomplished by changing only the component library
