A process-oriented event-based programming language

Proceedings of the 6th ACM International Conference on Distributed Event-Based Systems, 2012
We present the first version of PEPL, a declarative Process-oriented Event-based Programming Language based on the recently introduced Dynamic Condition Response (DCR) Graphs model. DCR Graphs allow for specification, distributed execution and verification of pervasive, event-based workflow and business processes by declaring condition, response ...

Low-Throughput Event-Based Image Sensors and Processing

2023 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2023
This paper presents new kinds of image sensors based on TFS (Time to First Spike) pixels and DVS (Dynamic Vision Sensor) pixels, which take advantage of non-uniform sampling and redundancy suppression to reduce the data throughput. The DVS pixels only detect a luminance variation, while TFS pixels quantized luminance by measuring the required time to ...

Event-Based Business Process Editor and Simulator

2011
The growing of business market dictates new requirements of agility to the business process environment. An event-driven approach can deal with this issue since an event can be defined as a significant change in the state of a system or an environment.

An Event-Based Framework for Process Inference

Proceedings of the AAAI Conference on Artificial Intelligence, 2011
We focus on a class of models used for representing the dynamics between a discrete set of probabilistic events in a continuous-time setting. The proposed framework offers tractable learning and inference procedures and provides compact state representations for processes which exhibit variable delays between events.

Event-Based Monitoring of Process Execution Violations

2011
Process-aware information systems support business operations as they are typically defined in a normative process model. Often these systems do not directly execute the process model, but provide the flexibility to deviate from the normative model. This paper proposes amethod for monitoring control-flow deviations during process execution.

On the Stability of an Event-based PI Controller for FOPDT processes

IFAC Proceedings Volumes, 2012
This paper deals with the stability of an event-based proportional-integral controller. In particular, necessary and sufficient conditions on the controller parameters for the existence of equilibrium points without limit cycles are given for a first-order-plus-dead-time process.

Complex Event Processing for Event-Based Process Querying

2019
Process querying targets the filtering and transformation of business process representations, such as event data recorded by information systems. This paper argues for the application of models and methods developed in the general field of Complex Event Processing (CEP) for process querying. Specifically, if event data is generated continuously during

Design of an event-based feedforward strategy for SOPTD processes

IEEE Conference on Decision and Control and European Control Conference, 2011
An event-based method to perform the set-point following task for second order processes with time delay (SOPTD) is investigated in this work. The aim of the research is to extend an event-based controller that has been tested previously in processes responding to the first-order with time delay (FOPTD) model. The controller is based on feedforward and

Point process models for event-based speech recognition

Speech Communication, 2009
Several strands of research in the fields of linguistics, speech perception, and neuroethology suggest that modelling the temporal dynamics of an acoustic event landmark-based representation is a scientifically plausible approach to the automatic speech recognition (ASR) problem. Adopting a point process representation of the speech signal opens up ASR

A model-driven approach for event-based business process monitoring

Information Systems and e-Business Management, 2013
Today event-driven business process management has matured from a scientific vision to a realizable methodology for companies of all sizes and shapes. However, leveraging the power of complex event processing for supporting business process monitoring is cumbersome because of the complicated modeling of rules and alerts as well as key performance ...
