Recently, the development of Industrial Internet of Things has made the emergence of innovative applications which are usually computation-intensive and latency-critical. In this paper, we study the task offloading in software-defined access network, where the industrial devices and edge computing servers are connected to wireless access points. To meet applications' requirements about latency and computing capacity and realize computational load balancing, we formulate a mixed integer non-linear program problem to minimize the overall cost. First, we propose an algorithm based on convex optimization and matching theory to minimize the overhead. Then, we consider load balancing of edge servers and extend our problem with regard to overhead and load balancing cost. We adopt alternating direction method of multipliers algorithm to solve the extended problem. Finally, simulation results demonstrate the effectiveness and superiority of our proposed algorithm.

Aiming at the characteristics of unstable wind power during the ship's sailing process, this paper uses a multi-lithium battery-supercapacitor hybrid energy storage system to store electrical energy, and stabilizes the severe fluctuations in wind power. The utilization of electrical energy in the ship's power grid has been improved. Utilizing the fast charging and discharging characteristics of supercapacitors, a control strategy for supercapacitor switching charging and discharging was designed to improve the energy utilization rate.

In the context of industry 4.0, it is strategic to support factories with innovative maintenance approaches, so to avoid faults and decrease the risks of a production stop. The first step of the digitization of factories has been the collection of large amounts of data monitoring the health status of the plant. However, such data is of little use unless it is clearly correlated with information about faults occurred on the line: some faults may be sporadic, or happen only in extremely critical conditions, and thus no data may be available related to their occurrence. Artificially generating such data would force to actually damage the plant, that is of course not a viable solution. The goal of this work is to generate faulty temporal series, that reproduce the behavior of a component on the occurrence of specific faults. The innovative approach models the component of interest in Verilog-AMS (VAMS) and systematically injects the faults of interest, by keeping a direct link with the real possible cause of such faulty behavior on the plant. To prove the effectiveness of the proposed solution, the approach is applied to a direct current motor (DC motor), an electromechanical system that converts electrical energy into mechanical energy.

The centralized computing model in traditional Wireless Sensor/Actuator Networks (WSANs) can lead to large delays and unbalances, which severely restricts the adoption of WSANs in applications requiring high network performance. To address this limitation, the in-network computation model has been proposed, in which the computation capability is distributed among wireless nodes in WSANs, i.e., wireless nodes perform not only data communication but also data processing. Node placement is a primary step to build the underlaying topologies of WSANs. Nevertheless, the problem of node placement to design underlaying network topologies supporting in-network computation is still unexplored. To this end, we propose an In-network-oriented Node Placement Algorithm (INPA) to build WSANs supporting in-network computation. Moreover, we investigate the time complexity of INPA and verify the efficiency of INPA through extensive simulations.

This paper presents a method on improving water pressure monitoring using wireless passive surface acoustic wave (WP-SAW) sensor. An experimental framework acting as water pipe simulator is built. Signal processing methods such as down-conversion, quadrature sampling, average, and multi-iterative two-point simple moving average (MI-2P-SMA) are utilized for improving sensing accuracy. The results show the relative errors of temperature at all testing points are less than 1% and the relative errors of pressure at all testing points are less than 2%.

The continuous growth of the naval and offshore industries require that the processes be steady and reliable, forcing the industries to keep up and dealing with the most modern methods of development. Among these processes, the welding is one of the most commons that has been used widely in the construction of oil platforms. The welding is used in many areas, beyond the naval, it being dangerous for the welder because the surroundings contain fumes and radiation. Once the welding is an usual procedure and the surroundings of the work space can be harmful to human's health, bring more automation for the welding process can improve the productivity levels and move human operators away from danger. However in the naval industry the projects are individualized, making the process of implementation of robotic cells difficult. Using modular robots turn the weld more reliable but are not a optimal solution due it still need a human operator near the process to change the robot's parameters and detect possible errors. So, this work proposes a architecture to turn these robots into autonomous systems, being able to detect the features of the groove to be weld, perform the welding with minimum of human interference or none and inspect the final product.

AFDX is the de facto communication standard in avionics domain. It is primarily used for the transmission of critical avionic flows. The mandatory certification process requires to upper bound the end-to-end transmission delay for each critical flow. Therefore, worst-case traversal time analysis has been implemented. However, it leads to a very lightly loaded network (up to 10%) as it considers very rare worst-case situations. Introducing a QoS mechanism is often a good solution to improve network utilisation since it allows differentiating critical flows based on their constraints as well as the transmission of less/non-critical flows with bounded impact on critical ones. Deficit Round Robin is such a mechanism and it is envisioned for future avionic networks. Using this mechanism, we propose to share the bandwidth between $n$ - 1 classes for critical flows and one class for non-critical ones. Therefore the contributions of this paper are (1) to propose a quantum assignment that ensures that critical flows always respect their deadlines and maximises the bandwidth for non-critical ones and (2) to propose a heuristic for the distribution of the flows among different classes.

The industrial fault text data are the special type of short texts, and they come from the records of faults in the factory. Clustering the industrial fault text data can reduce the redundant data and find out the hidden information, which is of great significance to improve the utilization of the industrial fault text data. The industrial fault text data are unstructured and irregular, so the clustering faces quite a few challenges. This paper introduces some existing algorithms for the clustering of short texts, and the shortcomings of them are briefly analyzed. This paper indicates that the main problem of the clustering of the industrial fault text data is the contradiction between the requirements and the setup of parameters, and it leads to low accuracy when cluster the corpus of different sizes. To increase the accuracy of clustering, an improved clustering algorithm is proposed which can solve this contradiction. The results of the comparative experiments show that the improved clustering algorithm has better performance than DBSCAN in corpus of different sizes on the industrial fault text data.
