The layered sodium transition metal oxide, NaTMO2 (TM = metal), with a binary or ternary phases has displayed outstanding electrochemical performance as new class of strategy cathode materials for sodium-ion batteries (SIBs). Herein, an in-depth phase analysis developed Na1-x TMO2 materials, Na0.76 Ni0.20 Fe0.40 Mn0.40 O2 P2- and O3-type (NFMO-P2/O3) is offered. Structural visualization on atomic scale also provided the following findings are unveiled: i) existence mixed-phase intergrowth...
The electromechanical brake (EMB) is a key component of the brake-by-wire (BBW) system generating clamping force between pad and disk through an electric motor mechanical transmission. Control has significant impact on performance. In this paper, EMB control developed that addresses several major challenges in practical implementation. Firstly, nonlinear model including DC motor, planetary gear set, ball screw, built. particular, novel introduced based linear transform two polynomial...
A bimodal redox-active ionic liquid electrolyte for high energy density supercapacitors was fabricated by the redox reaction of halide ions and size variation ions.
Ferroelectric columnar liquid crystals (FCLCs) with switchable bistable axial polarizations are promising candidates for high‐density ferroelectric random‐access memory (FeRAM). However, FCLCs simultaneously exhibiting uniform polarization arrangement and switching at room temperature (RT) remain elusive. Herein, we report an RT‐operable FCLC based on a C3‐symmetric star‐shaped mesogen polar linkers. Two CLCs, 1 2, were synthesized incorporating 1,2,3‐triazole amide linkers, respectively....
While vehicle to everything (V2X) communication enables safety-critical automotive control systems better support various connected services improve safety and convenience of drivers, they also allow attack surfaces increase dynamically in modern vehicles. Many researchers as well hackers have already demonstrated that can take remote the targeted car by exploiting vulnerabilities in-vehicle networks such Controller Area Networks (CANs). For assuring CAN security, we focus on how...
The violation of data integrity in automotive Cyber-Physical Systems (CPS) may lead to dangerous situations for drivers and pedestrians terms safety. In particular, cyber-attacks on the sensor could easily degrade accuracy consistency over any other attack, we investigate attack detection identification based a deep learning technology wheel speed sensors CPS. For faster recovery physical system with cyber-attacks, estimation specific value is conducted substitute false data. To best our...
The controller area network (CAN) is the de facto standard for in-vehicle networks. Numerous vehicles are equipped with a CAN networking of electronic control units. Since has no intrinsic secured identification protocol, however, it vulnerable to security attacks. In this paper, we propose convolution neural (CNN)-based message source identifier. proposed scheme uses physical characteristics bus channel, can be implemented without modification protocol.
Lithium vanadyl phosphate has seven different crystallographic phases. Among them, α‐LiVOPO 4 is chosen because of its relatively high energy density and redox voltage 3.9 V compared to the other phosphates. In this study, Ti 4+ ‐doped α‐LiV 1− x OPO ( = 0.00, 0.003, 0.005, 0.007, 0.01) was prepared using a sol–gel method increase structure stability electrochemical performance. The triclinic with space group P ‐1 confirmed by X‐ray diffraction, Fourier‐transform infrared spectroscopy,...
Abstract We report a three-dimensional (3D) molecular orientation control of liquid crystal organic semiconductor (LC-OSC) based on the long-range ordering characteristic an LC material. To this end, synthetic LC-OSC molecule, MeOPh-BTBT-C8, with fluidic nematic (N) phase that is essential for alignment over large area and smectic E (SmE) showing high ordering, was prepared. A simple flipping sandwich cell made material between top bottom substrates have uniaxial–planar degenerated as well...
Given the increased amount of data traffic in in-vehicle networks with more systems now included vehicles, enormous amounts research have recently focused on providing reliable and inexpensive quality service for communication systems. To support high-speed processing while maintaining backward compatibility controller area network (CAN) systems, turbo (TURBO CAN) was proposed, combining standard baseband CAN signal a passband modulated signal. In this paper, we demonstrate both an...
In the age of smart and connected vehicles, there are significant issues in providing security for in-vehicle networking. Many efforts networks still insufficient to build a lightweight mechanism. Typically, it comes from limitations Controller Area Network (CAN) protocol common network. We propose authentication method based on one-way hash chain CAN. addition, we identify three technical challenges be addressed proposed present our key idea address them.
This paper proposes the design of various end effectors for first aid robots. There is a growing demand special robots that perform rescue operations on behalf people in dangerous areas such as disasters or wars. In addition, when injuries occur, treatment also necessary. this paper, we user and system requirements performing propose effector suitable work.
