In linear wireless sensor networks, if the nodes can listen and receive packet at any time, a better balance between energy consumption and delay can be achieved by using opportunistic relay (such as TE-OR). In order to further reduce the network power consumption, the nodes need to be properly in a dormant state, which will affect the performance of opportunistic relay. Taking TE-OR algorithm as an example, this paper studies the effect of sleep on opportunistic relay. The simulation results show that in order to achieve the delay performance of the TE-OR algorithm without sleep, the duty cycle should reach more than 60%. In addition, it is difficult to optimize the energy consumption and delay performance simultaneously for the opportunistic relay with sleep. © 2018, Springer Nature Switzerland AG.

As for a pipe-line system subjected to complex operations, an approach is proposed to synthesize the controller via Petri nets (PNs) such that the plant is run as concurrently as possible and the loads of equipments are balanced. A P-timed and labeled PN is designed to model the whole process of a pipe-line system, where tasks, including transporting material from one tank to another and cleaning tank, are represented by operational places, and level sensors amounted in tanks are represented by labels assigned to transitions. Further, monitor places are designed to resolve the conflict relations among tasks due to the shared valves and pipes. An method is presented to translate an PN controller into a CIF3 (Compositional Interchange Format) model, which can be converted into a PLC program in the CIF3 tool. A beer filtration plant is taken as an example to illustrate the approach, and its simulation experiments are carried out to verify the theoretic results.

Entirely real eigenvalues emerge for non-Hermitian systems if their Hamiltonians are symmetric or antisymmetric under the parity-time (PT ) operations. This fact has led to many unconventional discoveries such as loss-induced lasing, sensor response enhancement and topological energy transfer. One merit of anti-PT systems is free of any gain, but nonlinear medium is still required in recent efforts on making and utilizing anti-PT devices. Here, counterintuitively, we propose to achieve a linear anti-PT device by combining dissipative optical coupling and the Sagnac frequency shifts of counterpropagating lights in a spinning resonator. Anti-PT symmetry and its spontaneous breaking can be well controlled by tuning the spinning velocity of the resonator. Compared with its Hermitian counterpart, 6 times enhancement of optical isolation and 2 orders enhancement of sensing response can be achieved by breaking the anti-PT symmetry. Configured as a new platform to study enhanced light-matter interactions, anti-PT resonators can also be used in such a wide range of fields as anti-PT lasers, anti-PT gyroscopes and anti-PT topological or chiral photonics.

Accurately monitoring health condition of individual lithium-ion (Li-ion) cells such as state of charge (SOC) and state of health (SOH) in multicell batteries is crucial to build high-performance and safety-critical battery systems. However, this involves considerable computational burden to embedded battery management systems (BMSs), as number of battery cells increases. This paper proposes an efficient on-board health monitoring method for multicell Li-ion battery systems consisting of large number of cells using the proposed Gaussian process clustering. The Gaussian process clustering method first preprocesses all cell voltages using Z-score standardization and classifies a normal cell cluster and an abnormal cell cluster using outlier scoring vector. Then, a representative of the normal cell cluster and abnormal cells are carefully monitored using the threads of a condition monitoring algorithm. Instead of using cell-based method for all cells in a pack, the proposed method can significantly reduce the computation cost for onboard implementation. We show the usefulness of the proposed health monitoring algorithm through simulation results. © 2018 IEEE.

In this paper, a novel distributed control strategy addressing a (feasible) psycho-social-physical welfare problem in islanded Direct Current (DC) smart grids is proposed. Firstly, we formulate a (convex) optimization problem that allows prosumers to share current with each other, taking into account the technical and physical aspects and constraints of the grid (e.g., stability, safety), as well as psycho-social factors (i.e., prosumers’ personal values). Secondly, we design a controller whose (unforced) dynamics represent the continuous time primal-dual dynamics of the considered optimization problem. Thirdly, a passive interconnection between the physical grid and the controller is presented. Global asymptotic convergence of the closed-loop system to the desired steady-state is proved and simulations based on collected data on psycho-social aspects illustrate and confirm the theoretical results.

This paper presents distributed event-triggered control and communication strategies for a group of autonomous agents to achieve consensus over unreliable communication channels. Communication is unreliable in the sense that the broadcast channel from one agent to its neighbors can drop the event-triggered packets of information, where the transmitting agent is unaware that the packet was not received and the receiving agents have no knowledge of the transmitted packet. Additionally, packets that successfully arrive at their destinations may suffer from time-varying communication delays. In this paper, we consider directed graphs, and also consider the general case of relaxed consistency on the packet dropouts and the delays. Relaxing consistency means that the delays and dropouts for a packet broadcast by one agent can be different for each receiving node. We show that even under this challenging scenario, agents can reach consensus asymptotically while reducing transmissions of measurements based on the proposed event-triggered consensus protocol. In addition, positive inter-event times are obtained which guarantee that Zeno behavior does not occur. © 2018 by the American Institute of Aeronautics and Astronautics, Inc.

Max-Min Fair Sensor Scheduling: Game-Theoretic Perspective and Algorithmic Solution

We consider the design of a fair sensor schedule for a number of sensors monitoring different linear time-invariant processes. The largest average remote estimation error among all processes is to be minimized. We first consider a general setup for the max-min fair allocation problem. By reformulating the problem as its equivalent form, we transform the fair resource allocation problem into a zero-sum game between a "judge" and a resource allocator. We propose an equilibrium seeking procedure and show that there exists a unique Nash equilibrium in pure strategy for this game. We then apply the result to the sensor scheduling problem and show that the max-min fair sensor scheduling policy can be achieved. Copyright © 2019, The Authors. All rights reserved.

Two main problems are addressed in this paper. The first one is the model identification for a commercial unmanned aircraft system (UAS): the Parrot Mambo multicopter. The second one aims at synthesizing a robust controller for guaranteeing the stability of the X and Y translational dynamics of this UAS. To accomplish these goals, we first collect input-output data from a set of real-time flight experiments. Next, by applying an extended least square (ELS) algorithm to the data, a group of dynamic models are identified. Due to uncertainties, the obtained models are similar in nature but exhibit parametrical variations. For this reason, from the set of identified models, a unique nominal (i.e., average) parameter-dependent linear model is built, which also takes into account the minimum and maximum values defining the model parametrical variations. Finally, a static linear controller is synthesized for the dynamics of interest, guaranteeing global stability for every model. The identification results and the performance of the closed- loop controller are validated in a set of numerical simulations, demonstrating the effectiveness of the proposed modeling and control approaches.

Computational prediction of the interaction between human leukocyte antigen (HLA) and peptide (pHLA) can speed up epitope screening and vaccine design. Here, we develop the TransMut framework composed of TransPHLA for pHLA binding prediction and AOMP for mutated peptide optimization, which can be generalized to any binding and mutation task of biomolecules. Firstly, TransPHLA is developed by using a Transformer-derived self-attention model to predict pHLA binding, which is significantly superior to 11 previous methods on pHLA binding prediction, neoantigen and human papilloma virus vaccine identification. For vaccine design, the AOMP program is then developed to automatically optimize mutated peptides to search for mutant peptides with higher affinity to the target HLA and with high homology to the source peptide. Among 3660 non-binding pHLAs, 3630 were successfully mutated. Of these, 94% were verified by the IEDB recommended method, and 88% have homology higher than 80% to the source peptide. © 2021, CC BY.
