In this study, a flexible and foldable frequency-reconfigurable antenna of liquid metal with cube structure is proposed. Based on the origami theory, the operating frequency of the antenna can be changed by folding the designed antenna to make it into a cube structure. The designed antenna does not have a rigid connection structure and has two modes: planer and folded modes. The re-flection coefficient of the antenna is 8.51-8.66 GHz (resonated at 8.59 GHz) and 12.54-12.83 GHz (resonated at 12.69 GHz) in the range below -10dB in the planer state and the 90° folded state, respectively. The antenna of this design has the characteristics of omnidirectional radiation, and the peak gain is 6.53 dBi. This work solves the problem of strain caused by traditional rigid materials and provides a liquid metal reconfigurable antenna that can be easily folded and used repeatedly.

In this paper, a high speed and low power double-edge triggered D flip-flop based on conditional discharge technique is proposed. By applying a scheme in the conditional discharge path, which takes the voltage difference between the internal node and the output node as the conduction condition, the circuit not only improves the circuit structure, but also reduces the power dissipation and the total power delay product. The simulation results show that the proposed D flip-flop has the correct logic function and is superior to other literatures in terms of power dissipation, delay and cost at the working frequency of 250MHz.

In Vehicular Ad Hoc Networks (VANETs), authentication is a crucial security service for both inter-vehicle and vehicle-roadside unit communications. Most of traditional protocols do not consider the impact of vehicular safety on authentication efficiency, thus implementing the same authentication process for all vehicles, which leads to large overhead and inflexible authentication. In this paper, we propose a differentiated identity authentication protocol based on vehicular safety level to reduce the authentication overhead and increase flexibility. In the proposed protocol, Roadside Unit (RSU) can choose appropriate authentication method for vehicle according to its safety level, which is evaluated by hardware safety and behavior safety. In addition, anonymous mutual authentication with key agreement is enabled by exploiting the trapdoor collision property of chameleon hash functions, thus the proposed protocol can effectively avoid the communication overhead caused by the transmission of certificates, and there is no key escrow problem. At the same time, combined with Physical Unclonable Functions (PUFs) technology, the proposed protocol can resist physical attacks. Simulation results demonstrate that the proposed protocol can not only effectively improve the flexibility of vehicular authentication, but also have advantages in reducing computation delay and communication overhead.

We proposed a novel curvature-sensitivity-enhanced optical fiber sensor realized by Bragg hollow core fiber (BHCF). The suspended hollow core fiber (SHCF) and the BHCF were connected between two single-mode fibers forming the sensor. The special construction of a four-bilayer Bragg structure provides a well-defined period interference envelope in the transmission spectrum for sensing external perturbations. Because of the different sensitivities of the interference dips, the proposed BHCF-SHCF-based sensor is able to simultaneously measure the parameter of curvature and temperature by monitoring the intensity fluctuation and wavelength shift, respectively. The highest curvature sensitivity of the proposed sensor is measured to be 0.36 dB/m-1 in the range of 1.283-3.247 m-1 with the adjusted R square value of 0.9895. Besides, the experiment of the temperature is also conducted, the results indicate the two measurands without crosstalk attributing to the different demodulation method.

This paper proposes a new digital compensation method for wideband phased array radar using nonlinear frequency modulated signal, which not only reduces the sampling rate of the echo but also obtains the low sidelobe without tapering and high-resolution range profile of the target. At the same time, the time delay differences caused by different array element positions are compensated. Computational results demonstrate both the compensation accuracy and the time-sampling efficiency of the proposed method.

There are massive electricity data in the daily management, normalization operation, troubleshooting and other aspects of the power domain, but these professional and accurate data have not been fully mined and used. Constructing a power domain knowledge map can not only help power grid companies tap the value of these massive data and realize the integration of power knowledge, but also greatly facilitate the staff's query and acquisition of power information, and improve the work efficiency of the power industry. NER (name entity recognition) is the basis for constructing knowledge graph. This paper studies name entity recognition based on dictionaries and rules. It can standardize and accurately extract electricity from unstructured text through three methods: power entity dictionary, feature character rule matching, and part-of-speech combination rule matching. Related entities provide high-quality and high-precision entities for the construction of power domain knowledge graph.

Based on the phase delay estimation of narrowband signals, a signal localization method is proposed in this paper by using a non-uniform linear array, which solves the phase wrapping problem caused by the increase of array element spacing and improves the accuracy of localization. This paper proposes an estimation algorithm for correcting the amount of wrapping and calculating the time delay in the case of nonuniform linear array approach, and gives the conditions that need to be satisfied for non-uniform array element spacing. The signal localization method improves the available array aperture for positioning and greatly reduces the number of array elements required for the same aperture compared to a general uniform linear array, thus reducing the need for subsequent signal processing equipment. A localization system is also constructed and tested. The experiments show that the method effectively improves the accuracy of localization of narrowband sound sources in open space.

Intent-driven network (IDN, also named as intent-based network, IBN) allows users to implement policies in a declarative way, instead of treating complete them in the underlying network. However, how to refine intent in natural language remains to be further researched. Although there exist emerging works on intent refinement, the problem of heterogeneous forms of intents in multiple carrier networks is still unsolved at present. As a formalized term set, ontology makes it possible to unify the various terms at the semantic level. The ontology-based architecture of IDN consists of the application layer, the intent-enabled layer, and the infrastructure layer. Users can input intent in the application layer in various ways, and the input intent can be converted into an intent tuple as . The intent-enabled layer constructs an intent ontology, on the basis of intent tuple and network configuration protocol (NETCONF) information from the infrastructure layer. In addition, the refined intent can be verified both in natural language processing (NLP) level and the semantic level. In this paper, we design an intelligent intent refinement system to accomplish intent refinement.

In Wireless Sensor Networks (WSNs), sensors collect and transmit information to the sink node through single-hop or multi-hop wireless communication links. However, the traditional static sink node solution will cause the hotspot problem due to the energy limitation of sensor nodes. To alleviate the above problem, the Unmanned Aerial Vehicle (UAV)-assisted WSNs, which employs a UAV as the sink node, is proposed to flexibly adjust the routing scheme and prolong the lifetime of sensor nodes. However, the movement of the UAV needs to adapt to the sensor nodes' energy consumption during the transmission in the WSNs, which is a challenging task. Therefore, we propose DRED, an energy-efficient data collection scheme for UAV-assisted WSNs, to control the dynamic routing and the movement of the UAV based on Deep Reinforcement Learning (DRL). The simulation results show that DRED can achieve high network performance in terms of network lifetime.

Operating cables will inevitably undergo insulation aging due to the influence of electric field, magnetic field, heat, light, moisture and other factors, and the insulation performance will be significantly reduced. Statistics show that cable joint failure is one of the important causes of cable failure. The multi-physical field coupling model adopts a variety of physical field interfaces such as electric and acoustic coupling to simulate the discharge waveforms and waveform propagation forms generated by cable joint defects. Firstly, the relationship between voltage and insulation fault is established, and the cable insulation fault is diagnosed by the electric field characteristics. In addition, the electric field characteristics are used to reflect the location of charge agglomeration area, and then the discharge signal at this location is detected to diagnose the deterioration degree of insulation materials.
