The following paper describes a concept for a grasping application which utilizes technologies from the fields of distributedcomputing, robotics and Digital Twins in the sense of Industry 4.0. Hereby, the goal of the application is to have a computer vision system detect toy bricks which a robot has to pick and pass to a user. The application is divided into loosely coupled and distributed services that communicate with one another using a message broker.
A distributed wireless communication system consists of multiple nodes. Due to the diversified resources and environmental conditions for each node, a consensus-based algorithm can be used to solve the conflicts in th...

We present a simple algorithmic framework for designing efficient distributed algorithms for the fundamental symmetry breaking problem of Maximal Independent Set (MIS) in the sleeping model [Chatterjee et al, PODC 2020]. In the sleeping model, only the rounds in which a node is awake are counted for the awake complexity, while sleeping rounds are ignored. This is motivated by the fact that a node spends resources only in its awake rounds and hence the goal is to minimize the awake complexity. Our framework allows us to design distributed MIS algorithms that have O (polyloglog(n)) (worst-case) awake complexity in certain important graph classes which satisfy the so-called adjacency property. Informally, the adjacency property guarantees that the graph can be partitioned into an appropriate number of classes so that each node has at least one neighbor belonging to every class. Graphs that can satisfy the adjacency property are random graphs with large clustering coefficient such as random geometric graphs as well as line graphs of regular (or near regular) graphs. We first apply our framework to design two randomized distributed MIS algorithms for random geometric graphs of arbitrary dimension d (even non-constant). The first algorithm has O(polyloglog n) (worst-case) awake complexity with high probability, where n is the number of nodes in the graph.' This means that any node in the network spends only O(polyloglog n) awake rounds;this is almost exponentially better than the (traditional) time complexity of O(log n) rounds (where there is no distinction between awake and sleeping rounds) known for distributed MIS algorithms on general graphs or even the faster O(root log n/log log n ) rounds known for Erdos-Renyi random graphs. log log n However, the (traditional) time complexity of our first algorithm is quite large-essentially proportional to the degree of the graph. Our second algorithm has a slightly worse awake complexity of O(d polyloglog n), but achieves a sig

In the domain of safety critical real-time computing, the ever increasing demand for processing power and robust safety guarantees has fueled the development of solutions to support the development of multicore and multi-CPU distributed software architectures. These architectures offer the potential for achieving enhanced computational power by exploiting the high-level of hardware parallelism, but they also raise significant challenges in ensuring temporal guarantees, such as the absence of deadlocks and race conditions, compliance with time budgets, etc. In this paper we present our ongoing work of developing a workflow for developing multi-CPU software applications from high level requirements down to the integrated system. The workflow is supported by several models and is specified with the FTG+PM formalism. We illustrate the workflow using two industrial applications from the aeronautical domain.

Microseismic detection events are critical in monitoring subsurface activities, including hydraulic fracturing, enhanced oil recovery, carbon dioxide, or natural gas geological storage and reservoir characterization, to guarantee safe and efficient energy extraction. This presents significant challenges as it generates large amounts of data. Despite the recent machine learning techniques being increasingly integrated into fiber-optic distributed acoustic sensor (DAS) systems to enhance their intelligent recognition capabilities, there is still a need to solve this. In some research, it has been observed that computational speed is time-consuming and overfitting, thus necessitating a more extensive investigation of this analysis. This study proposes a novel approach using DAS data to enhance microseismic event detection's precision, overfitting issue, and interpretability. This approach utilizes a specifically designed neural network architecture. The deep learning approach is highly effective for the real-time management of the substantial amounts of data recorded by DAS equipment. Three phases of research methodology are proposed. The contribution of this research is that spiking neural network architecture for microseismic detection will bring advancements in microseismic monitoring.
