Title: Cellular Internet of Things Versus Cell-Free Internet of Things

Abstract: With the proliferation of Internet of things (IoT) applications, the massive machine-type connections bring great challenges to traditional cellular networks, wherein cell-boundary devices with severe path-loss and inter-cell interference normally suffer from poor performance. By contrast, cell-free massive MIMO is a promising technique to support massive MTCs, since its user-centric architecture can shorten the distance between devices and access points, and boost the network coverage performance significantly. The key research topics and several promising solutions will be introduced.

Title: Research on life prediction of supercapacitor based on improved long-term and short-term memory neural network

Abstracts: Long short-term memory neural network optimized based on hybrid genetic algorithm is proposed to predict the remaining useful life of supercapacitors. First, determine the input variables of the deep neural network. By analyzing the structural characteristics between the electrode and the solution, and the characteristics and laws of the movement of internal charges, the energy storage mechanism of the supercapacitor is studied, and the influencing factors of the supercapacitor performance aging are obtained. The input variables of the neural network model are determined according to the influencing factors of the performance aging of the supercapacitor, in order to achieve accurate prediction of the remaining useful life of the supercapacitor. Secondly, two tests are designed to obtain supercapacitor aging data. A large amount of data is the basis of high precision for life prediction, to fully reflect the aging condition of the power supply under different running environment, this paper uses different charge and discharge strategies based on different temperatures and voltages to perform a steady-state cycle life test and Hybrid Pulse Power Characteristic test on the supercapacitors to make the measured data more real and effective.

TitleBandit Algorithms for Channel Selection in Remote State Estimation

AbstractWe consider a remote state estimation problem where, at each discrete time instant, a wireless sensor has several different communication channels to choose from. These channels are unreliable and introduce random packet dropouts in the communication between the sensor and the remote estimation system. To achieve satisfactory estimation performance, the best channel needs to be selected. A key difficulty of the situation at hand is that the channel dropout probabilities are unknown. We study the case where both learning of the channel reception probabilities and state estimation are carried out simultaneously. Methods for choosing the channels based on techniques for multi-armed bandits are presented and shown to ensure stability of the remote estimator. Furthermore, we define the performance notion of estimation regret, and derive bounds on how it scales with time for the considered algorithms.

Title: Swarm Intelligence for Dynamic Optimization Problems

AbstractSwarm intelligence (SI) in biology represents the property that the collective behavior of a swarm of agents that interact locally with their environment causes coherent functional global patterns to emerge. SI algorithms are optimization algorithms inspired from the SI phenomena in biology, such as ant foraging and bird flocking, and have been applied in different fields. Most SI algorithms have been developed to address stationary problems. However, many real-world problems are dynamic optimization problems (DOPs) that are subject to changes over time. DOPs have attracted a growing interest from the SI community in recent years due to the importance in the real-world applications of SI algorithms. This talk will first briefly introduce the concepts of SI and DOPs, review the enhancement strategies integrated into SI algorithms to address DOPs, and then describe several detailed case studies on SI methods for DOPs. Finally, some conclusions will be made and the future work on SI for DOPs will be briefly discussed.

Title: Preparation and Thermal Characteristics of Nano-based PCMs

Abstract: To address the low thermal conductivity of the PCMs, nanoparticles are widely recommended to suspend in the base fluids. Different mass fractions of nanoparticles dispersed in the base PCMs. The dispersion stability of the nanofluids employed as PCMs has been clearly ascertained by means of the sedimentation photograph and particle size analyzer. The thermophysical properties of the nanofluids, like phase change temperature and latent heat, have been measured by differential scanning calorimetry. The thermal stability and reliability analyses were studied to evaluate the performance of the nanofluids for long-term operation. The effects of the concentration of nanoparticles and operating temperature of the PCMs on the viscosity of the nanofluids have been investigated. The laser flash analyzer has been used to ascertain the thermal conductivity enhancement of the nanofluids for all mass fractions of nanoparticles.
