“…Communication through a Message Oriented Middleware can also provide characteristics such as loose coupling and better performance [15]. Among the ones that exist in the market, the RabbitMQ solution [16] (which was chosen to be used in the pilot described in this paper) is an open source solution that supports multiple communication protocols, is proven to be very reliable and well tested, allows for flexible routing, and supports several topologies.…”

-The reliability and safety of industrial machines depends on their timely maintenance. The integration of Cyber Physical Systems within the maintenance process enables both continuous machine monitoring and the application of advanced techniques for predictive and proactive machine maintenance. The building blocks for this revolution -embedded sensors, efficient preprocessing capabilities, ubiquitous connection to the internet, cloud-based analysis of the data, prediction algorithms, and advanced visualization methods -are already in place, but several hurdles have to be overcome to enable their application in real scenarios, namely: the integration with existing machines and existing maintenance processes. Current research and development efforts are building pilots and prototypes to demonstrate the feasibility and the merits of advanced maintenance techniques, and this paper describes a system for the industrial maintenance of sheet metal working machinery and its evolution towards a full proactive maintenance system.

The amount profile is a sequence of (m ∈ N >0 ) consecutive slices, P (f ) = s (1) Figure 2 illustrates FO f = ( [1,5], [3,5], [2,3] An FO captures all possible amount demands and/or supplies of a device for a given time horizon. However, during the scheduling process, an FO is assigned to a specific amount at a specific time resulting in an assignment of the FO defined as follows: Definition 2.…”

Abstract-The flexibility of individual energy prosumers (producers and/or consumers) has drawn a lot of attention in recent years. Aggregation of such flexibilities provides prosumers with the opportunity to directly participate in the energy market and at the same time reduces the complexity of scheduling the energy units. However, aggregated flexibility should support normal grid operation. In this paper, we build on the flex-offer (FO) concept to model the inherent flexibility of a prosumer (e.g., a single flexible consumption device such as a clothes washer). An FO captures flexibility in both time and amount dimensions. We define the problem of aggregating FOs taking into account grid power constraints. We also propose two constraintbased aggregation techniques that efficiently aggregate FOs while retaining flexibility. We show through a comprehensive evaluation that our techniques, in contrast to state-of-the-art techniques, respect the constraints imposed by the electrical grid. Moreover, our techniques also reduce the scheduling input size significantly and improve the quality of scheduling results.

“…XMPP was originally designed for instant messaging (IM), but has been used as a core enabling technology for multi-player games (Lee, 2004), Internet of Things (IoT) (Schuster et al, 2014), as well as cloud computing (Bernstein et al, 2009) and grid computing (Albano et al, 2015) (see (Hornsby and Walsh, 2010) for an overview). It has thus been demonstrated that the XMPP protocol can be used in a wide variety of applications where the common denominator is connecting humans and/or systems, often with real-time constraints and on a massive scale.…”

Abstract:The study of human behavior must take into account the social context, and real-time, networked experiments with multiple participants is one increasingly popular way to achieve this. In this paper a framework based on Python and XMPP is presented that aims to make it easy to develop such behavioral experiments. An illustrative example of how the framework can be used is also presented. This example is a real experiment, which is currently gathering data in the lab.
