This paper investigates the optimal design of wireless powered fog computing networks, where a hybrid access point integrated with fog computing function (F-HAP) first charges an Internet of Things (IoT) device via wireless power transfer (WPT), and then the IoT device uses the harvested energy to compute real-time updates locally or offload the updates to the F-HAP for computing. For such a system, an age-energy aware cost function is defined to evaluate the system performance, based on which, an optimization problem is formulated to explore the minimum age-energy aware cost by jointly optimizing the time assignment, the transmit power, the computing frequency, as well as the computing mode selection, such that the given data processing task can be completed. Since the problem is non-convex with the discrete binary variable, variable substitution and Karush-Kuhn-Tucker (KKT) conditions are applied to solve it and some closed-form results on the optimal solution are derived. Numerical results show that the transmit power has much greater effects on the age-energy performance of the fog offloading mode than on that of the local computing mode. Moreover, when the IoT device is relatively close to the F-HAP, fog offloading is a better choice; Otherwise, local computing should be selected.

As a rising branch of advanced oxidation processes, persulfate activation has attracted growing attention. Unlike catalysts that have been widely studied, the selection of persulfate is previously overlooked. In this study, the affecting factors of persulfates were studied. The effect of target pollutant properties on superior persulfate species (the species with a higher degradation efficiency) was investigated by multiwalled carbon nanotube (MWCNT)/persulfate catalytic systems. Innovatively, the E (or vertical ionization potential (VIP)) value of the target pollutant was proposed to be an index to judge the superior persulfate species, and the threshold is VIP= 6.397-6.674 eV, E= -8.035∼- 7.810 eV, respectively. To be specific, when the VIP of phenolic compounds is higher (or E of phenolic compounds is lower) than the threshold, the catalytic performance of peroxymonosulfate would be higher than that of peroxydisulfate. Moreover, the effects of coexisting cations on peroxydisulfate superior species were further investigated. It was illustrated that the hydrated cation radius of coexisting cations would influence the pollutant degradation efficiency under some circumstances. This study provides a new approach to improve the cost of persulfate activation systems and promotes the underlying downstream application of persulfate activation systems.

KAGRA is the 2.5th generation gravitational wave detector in Japan. There are two unique features in KAGRA detector, one is the underground environment and the other is the cryogenics. Those two features would be the essential technique toward the next generation detector. Toward the observation, we installed various environmental monitors such as accelerometers, magnetometers, seismometers, microphones, temperature and humidity monitors, air pressure monitors, voltage monitors and so on. In addition to this, we established the portable environmental monitoring system for detector noise hunting. Those environmental monitors are also used for the R&D studies for the future gravitational wave detectors.. In this talk, we will present the investigation of the environmental noise at KAGRA detector and current status of the noise hunting using environmental monitors. © Copyright owned by the author(s) under the terms of the Creative Commons.

Organic pollutants removal from water is pressing owing to the great demand for clean water. Oxidation processes (OPs) are the commonly used method. However, the efficiency of most OPs is limited owing to the poor mass transfer process. Spatial confinement is a burgeoning way to solve this limitation by use of nanoreactor. Spatial confinement in OPs would (i) alter the transport characteristics of protons and charges; (ii) bring about molecular orientation and rearrangement; (iii) cause the dynamic redistribution of active sites in catalyst and reduce the entropic barrier that is high in unconfined space. So far, spatial confinement has been utilized for various OPs, such as Fenton, persulfate, and photocatalytic oxidation. A comprehensive summary and discussion on the fundamental mechanisms of spatial confinement mediated OPs is needed. Herein, the application, performance and mechanisms of spatial confinement mediated OPs are overviewed firstly. Subsequently, the features of spatial confinement and their effects on OPs are discussed in detail. Furthermore, environmental influences (including environmental pH, organic matter and inorganic ions) are studied with analyzing their intrinsic connection with the features of spatial confinement in OPs. Lastly, challenges and future development direction of spatial confinement mediated OPs are proposed.

This paper formulates and studies the problem of controlling a networked SIS model using a single input in which the network structure is described by a connected undirected graph. A necessary and sufficient condition on the values of curing and infection rates for the healthy state to be exponentially stable is obtained via the analysis of signed Laplacians when the control input is the curing budget of a single agent. In the case when the healthy state is stabilizable, an explicit expression for the minimum curing budget is provided. The utility of the algorithm is demonstrated using a simulation over a network of cities in the northeastern United States.

Vehicles were operating as platoon is a fundamental approach to solve the problem of road traffic efficiency. When a vehicle travels in the two-lane highway, it could overtake only by using the opposing lane. The platoon makes the ego vehicle face the problem of overtaking, which not only interfering with the traffic efficiency improving but also adding the risk of collision. In order to solve this problem, a step-by-step VOPDS (vehicle overtakes the platoon based on driving style) algorithm was proposed, in which an optimal speed matching scheme by researching the relationship between the speed of vehicles before the slot, the speed of vehicles behind the slot, the speed of vehicle joining a platoon and the required safety slot was designed. Also, a Hierarchical Constrained Multi-objective Optimization Method Based on Improved Particle Swarm Optimization is proposed, which provides the optimized speed guidance strategy for the vehicle overtaking a platoon model. In order to make the speed guidance information be accepted by drivers, this paper got driver behavior characteristics statistics by using open-source driving-simulation tool CARLA, through experiments. The algorithm-simulation results imply that the improved particle swarm optimization algorithm has stronger robustness and faster convergence than the traditional algorithms, optimized results which be more in line with drivers' driving style showed an improved both overall operating efficiency and comfortable for single vehicle overtaking a platoon scenario. © 2019 IEEE.

The DC transformers (DCTs) can achieve flexible power flow control in the ring-type and meshed-type multi-terminal DC grids with less loss. However, due to the limited power flow control range of the DCTs, the power flow controller (PFC) is expected to boost the system's controllability. Unlike the conventional DCTs, this paper proposes an embedded DC power flow controller (e-DCPFC) formed by a PFC and an input-series-output-parallel (ISOP) DCT. This device has the features of multiple ports and extended bidirectional power flow control capability. The operational principle of the e-DCPFC is analysed in detail. And a modified input voltage sharing (m-IVS) control strategy is proposed in this paper. This control scheme not only maintains the input capacitor voltage balanced of the ISOP structure but also controls the power of the extra ports provided by the e-DCPFC. The feasibility and effectiveness of the proposed topology and control strategy are verified via MATLAB simulation mode.

This paper describes control design considering magnetic flux characteristic uncertainty for magnetic levitation system with magnetic flux and current feedback. The position of the levitated object is calculated from the hall voltage and current of the electromagnet. We show the uncertainty for magnetic flux characteristic and design the stabilizing controller by proportional feedback with the hall voltage and current. Moreover, we tried to design servo controller by two-degree-of-freedom control by using a finite number of frequency response (FNFR) model including the uncertainty and confirmed the validity of the proposed method by experiment results. © 2019 The Institute of Eleclrical Engineers of Japan.

Biochar has been frequently used as a persulfate (PS) activator due to its attractive properties, but dissolved organic matter (DOM) derived from the non‑carbonized part of biochar has received less attention, not to mention its specific role and impact in biochar/PS systems. In this study, wheat straw, municipal sludge, and swine bone were selected as the representative feed stocks of biochar. Subsequently, these three types of biochar were adopted to explore the roles of DOM in biochar/PS systems. Although the composition and amount of DOM derived from different biochar were discrepant, they exhibited similar effect in biochar/PS systems. To be specific, the pore-clogging effect of DOM on biochar suppressed the adsorption capacity and catalytic performance of the three biochar. Furthermore, the removal of DOM decreased the environmental risk of these biochar/PS systems and enhanced the stability of the involved biochar. With respect to the variation in degradation mechanism, the removal of DOM increased the proportion of electron transfer pathway in unison, but the diminution in the roles of O and O was more remarkable in bone-derived-biochar/PS systems. Additionally, the toxicity test illustrated that the leakage and accumulation of DOM were toxic to Chlorella sp., and the DOM from sludge-derived-biochar presented the highest toxicity. Overall, this study analyzes the roles of DOM derived from different biochar in biochar/PS systems and evaluates their environmental risk, which contributes to a comprehensive understanding of the fate of DOM derived from biochar.
